The naturally microstructure-bioinspired piezoresistive sensor for human-machine interaction and human health monitoring represents an attractive opportunity for wearable bioelectronics. However, due to the trade-off between sensitivity and linear detection range, obtaining piezoresistive sensors with both a wide pressure monitoring range and a high sensitivity is still a great challenge. Herein, we design a hierarchically microstructure-bioinspired flexible piezoresistive sensor consisting of a hierarchical polyaniline/polyvinylidene fluoride nanofiber (HPPNF) film sandwiched between two interlocking electrodes with microdome structure. Ascribed to the substantially enlarged 3D deformation rates, these bioelectronics exhibit an ultrahigh sensitivity of 53 kPa, a pressure detection range from 58.4 to 960 Pa, a fast response time of 38 ms, and excellent cycle stability over 50 000 cycles. Furthermore, this conformally skin-adhered sensor successfully demonstrates the monitoring of human physiological signals and movement states, such as wrist pulse, throat activity, spinal posture, and gait recognition. Evidently, this hierarchically microstructure-bioinspired and amplified sensitivity piezoresistive sensor provides a promising strategy for the rapid development of next-generation wearable bioelectronics.

Gualou Xiebai Banxia decoction ameliorates Poloxamer 407-induced hyperlipidemia.

Biosci Rep 2021 Jun;41(6)

Department of Operational Medicinal Research, Tianjin Institute of Environmental and Operational Medicine, Tianjin 300050, China.

Ethnopharmacological Relevance: Gualou Xiebai Banxia (GLXBBX) decoction is a well-known traditional Chinese herbal formula that was first discussed in the Synopsis of the Golden Chamber by Zhang Zhongjing in the Eastern Han Dynasty. In traditional Chinese medicine, GLXBBX is commonly prescribed to treat cardiovascular diseases, such as coronary heart disease and atherosclerosis.

Objective: The present study aimed to examine GLXBBX's preventative capacity and elucidate the potential molecular mechanism of Poloxamer 407 (P407)-induced hyperlipidemia in rats.

Materials And Methods: Both the control and model groups received pure water, and the test group also received a GLXBBX decoction. For each administration, 3 ml of the solution was administered orally. To establish hyperlipidemia, a solution mixed with 0.25 g/kg P407 dissolved in 0.9% normal saline was injected slowly into the abdominal cavity. At the end of the study, the rats' plasma lipid levels were calculated using an automatic biochemical analyzer to evaluate the preventative capability of the GLXBBX decoction, and the serum and liver of the rats were collected.

Results: The GLXBBX decoction significantly improved P407-induced hyperlipidemia, including increased plasma triglycerides (TGs), aspartate aminotransferase (AST) elevation, and lipid accumulation. Moreover, GLXBBX decoction treatment increased lipoprotein lipase (LPL) activity and mRNA expression of LPL. Furthermore, GLXBBX significantly suppressed the mRNA expression of stearoyl-CoA desaturase (SCD1).

Conclusion: GLXBBX significantly improved P407-induced hyperlipidemia, which may have been related to enhanced LPL activity, increased LPL mRNA expression, and decreased mRNA expression of SCD1.

Protective effect of aldehyde dehydrogenase 2 against rat corneal dysfunction caused by streptozotocin-induced type I diabetes.

Exp Biol Med (Maywood) 2021 May 8:15353702211013308. Epub 2021 May 8.

Traditional Chinese Medicine (TCM) Department, General Hospital of Western Theater Command, Chengdu 610083, PR China.

Aldehyde dehydrogenase 2 plays a pivotal role in detoxifying aldehydes, and our previous study revealed that aldehyde dehydrogenase 2 could alleviate diabetic retinopathy-associated damage. We aimed to characterize the potential role of aldehyde dehydrogenase 2 in diabetic keratopathy. Twenty-four rats with streptozotocin-induced (60 mg/kg, single intraperitoneal injection) type 1 diabetes mellitus (T1DM) were divided the T1DM group and the T1DM + Alda1 (an activator of aldehyde dehydrogenase 2) group (5 mg/kg/d, intraperitoneal injection, 1/2/3 months), while an additional 12 healthy rats served as the control group. Corneal morphology was examined and at one, two, and three months after T1DM induction. Additionally, serum inflammatory factors were measured by ELISA, and the expression of corneal vascular endothelial growth factor A (VEGF-A) and aldehyde dehydrogenase 2 was measured by immunofluorescence staining. Corneal cell death was evaluated by terminal-deoxynucleotidyl transferase-mediated nick end labeling (TUNEL) staining. Slit lamp analysis showed that the area of corneal epithelial cell injury in the T1DM + Alda1 group was significantly smaller than that in the T1DM group at one and two months after T1DM induction (all <0.05). OCT analysis and HE staining showed that the central corneal thickness (indication of corneal edema) and the epithelial keratinization level in the T1DM + Alda1 group was evidently decreased compared with those in the T1DM group (all <0.05). The serum inflammatory factors interleukin-1 and interleukin-6 were significantly upregulated in the T1DM group compared with the T1DM + Alda1 group at three months after T1DM induction (all <0.05), while there were no differences in SOD or TNF-α levels among all groups. Furthermore, corneal VEGF-A expression and corneal cell death in the T1DM + Alda1 group were dramatically reduced compared to those in the T1DM group (all <0.05). In conclusion, the aldehyde dehydrogenase 2 agonist Alda1 attenuated rat corneal dysfunction induced by T1DM by alleviating corneal edema, decreasing corneal cell death, and downregulating corneal VEGF-A expression.

Dexmedetomidine attenuates lipopolysaccharide-induced acute liver injury in rats by inhibiting caveolin-1 downstream signaling pathway.

Biosci Rep 2021 Mar;41(3)

Department of Anesthesiology, Huzhou Maternal and Child Health Care Hospital, Huzhou, Zhejiang Province, China.

Objective: The aim of the present study is to investigate the anti-injury and anti-inflammatory effects of dexmedetomidine (Dex) in acute liver injury induced by lipopolysaccharide (LPS) in Sprague-Dawley rats and its possible mechanism.

Methods: The acute liver injury model of male rats was established by injecting LPS into tail vein. The mean arterial pressure (MAP) of rats was recorded at 0-7 h, and lactic acid was detected at different time points. Wet/dry weight ratio (W/D) was calculated. Pathological changes of rat liver were observed by HE staining. ALT and AST levels in serum were detected. The activities of myeloperoxidase (MPO) and superoxide dismutase (SOD) in liver tissue homogenate and the levels of IL-1β and IL-18 in serum were detected by ELISA. Protein levels of Caveolin-1 (Cav-1), TLR-4 and NLRP3 in liver tissue were tested by immunohistochemistry method. The expression of Cav-1, TLR-4 and NLRP3 mRNA in liver tissue was detected by quantitative polymerase chain reaction (qPCR) to explore its related mechanism.

Results: Compared with NS group, serum lactic acid, W/D of liver tissue, MPO, SOD, IL-1β and IL-18 were significantly increased and MAP decreased significantly in LPS group and D+L group. However, compared with NS group, D group showed no significant difference in various indicators. Compared with LPS group, MPO, SOD, IL-1β and IL-18 were significantly decreased and MAP was significantly increased in D+L group. D+L group could significantly increase the level of Cav-1 protein and decrease the level of TLR-4 and NLRP3 protein in liver tissue caused by sepsis. The expression of Cav-1 mRNA was significantly up-regulated and the expression of TLR-4 and NLRP3 mRNA was inhibited in D+L group.

Conclusion: Dex pretreatment protects against LPS-induced actue liver injury via inhibiting the activation of the NLRP3 signaling pathway by up-regulating the expression of Cav-1 by sepsis.

Recent advances of dual FGFR inhibitors as a novel therapy for cancer.

Eur J Med Chem 2021 Mar 23;214:113205. Epub 2021 Jan 23.

Personalized Drug Therapy Key Laboratory of Sichuan Province, Department of Pharmacy, Sichuan Academy of Medical Sciences & Sichuan Provincial People's Hospital, School of Medicine, University of Electronic Science and Technology of China, Chengdu, Sichuan, 610072, China. Electronic address:

Fibroblast growth factor receptor (FGFR) includes four highly conserved transmembrane receptor tyrosine kinases (FGFR1-4). FGF and FGFR regulate many biological processes, such as angiogenesis, wound healing and tissue regeneration. The abnormal expression of FGFR is related to the tumorigenesis, tumor progression and drug resistance of anti-tumor treatments in many types of tumors. Nowadays there are many anti-cancer drugs targeting FGFR. However, traditional single-target anti-tumor drugs are easy to acquire drug resistance. The therapeutic effect can be enhanced by simultaneously inhibiting FGFR and another target (such as VEGFR, EGFR, PI3K, CSF-1R, etc.). We know drug combination can bring problems such as drug interactions. Therefore, the development of FGFR dual target inhibitors is an important direction. In this paper, we reviewed the research on dual FGFR inhibitors in recent years and made brief comments on them.

RBM10 regulates human TERT gene splicing and inhibits pancreatic cancer progression.

Am J Cancer Res 2021 1;11(1):157-170. Epub 2021 Jan 1.

Department of Pharmacy, The General Hospital of Western Theater Command of PLA Chengdu 610083, China.

Dysregulation of alternative splicing of hTERT gene to generate full-length Htert (hTERT-FL) that reactivate telomerase has been recognized as a major pathological alteration in pancreatic cancer (PrCa). Mechanism about the factors that regulate hTERT-FL splicing is lacking. Through bioinformatics approach, we focus on a candidate splicing factor RBM10, which leads to a switch in hTERT transcripts to generate a function-less isoform hTERT-s in PrCa, suppressed both telomerase activity and subsequent telomere shortening. RBM10 expression is negatively associated with PrCa progression. Gain or loss of RBM10 also significantly changed PrCa cell proliferation in vitro and in xenografts. RNA-IP and RNA pull-down assays reveal that RBM10 promotes the exclusion of exons7 and 8 which results in the production of TERT-s transcripts. This study may increase knowledge about potentially targetable cancer associated splicing factors and provide novel insights into therapeutic approach in PrCa.

Chinese medicinal plants for the potential management of high-altitude pulmonary oedema and pulmonary hypertension.

Pharm Biol 2020 Dec;58(1):815-827

Department of Central Laboratory, The General Hospital of Western Theater Command, Chengdu, Sichuan, P. R. China.

Context: Despite the abundance of knowledge regarding high-altitude pulmonary edoema (HAPE) and high-altitude pulmonary hypertension (HAPH), their prevalence continues to be on the rise. Thus, there is an urgent need for newer safe, effective, and relatively economic drug candidates. China is particularly known for the use of medicinal plants.

Objective: This review summarizes the medicinal plants used for HAPE and HAPH in the past 30 years, as well as some potential plants.

Methods: Publications on HAPE and HAPH from 1990 to 2020 were identified using Web of Science, PubMed, SCOPUS, Springer Link, Google Scholar databases, Chinese Clinical Trial Registry and CNKI with the following keywords: 'medicinal plants,' 'hypoxia,' 'high altitude pulmonary edema,' 'high altitude pulmonary hypertension,' 'pathophysiology,' 'mechanisms,' 'prevention,' 'treatment,' 'human,' 'clinical,' 'safety,' and 'pharmacokinetics.'

Results: We found 26 species (from 20 families) out of 5000 plants which are used for HAPE and HAPH prevention or treatment. Linn. (Crassulaceae) is the most widely utilized. The most involved family is Lamiaceae, which contains 5 species.

Discussion And Conclusions: We mainly reviewed the medicinal plants and mechanisms for the treatment of HAPE and HAPH, and we also assessed related toxicology experiments, pharmacokinetics and bioavailability. Potential medicinal plants were also identified. Further research is needed to determine the pharmacological effects and active ingredients of these potential medicinal plants.

Effect of hand-ear acupuncture on chronic low-back pain: a randomized controlled trial.

J Tradit Chin Med 2019 08;39(4):587-598

Traditional Chinese Medicine Department, The General Hospital of Western Theater Command, Chengdu 610083, China.

Objective: To evaluate the effect of hand-ear acupuncture on chronic low-back pain (cLBP).

Methods: This was an open, randomized and controlled trial in The General Hospital of Western Theater Command, Sichuan Province. The trial was registered with ClinicalTrials.gov, NCT02260284. All the 152 participates with cLBP were randomly assigned to hand-ear acupuncture (n = 54), standard acupuncture (n = 50), or usual care groups (n = 48). Eighteen treatments were provided over 7 weeks. Back-related dysfunction and symptom severity were assessed by the Roland-Morris Disability Questionnaire (RMDQ) and the Visual Analogue Scale (VAS), which were collected at baseline, 2 months and 6 months post to the treatment.

Results: At 6 months, the RMDQ scores improved by 7.74 points of hand-ear acupuncture group. Significant improvement of VAS and RMDQ was observed in hand-ear acupuncture group (P < 0.001), but no significant changes of RMDQ were observed in both standard acupuncture group and usual care group. We also observed an overall efficacy rate of 88.89% in hand-ear acupuncture group, as evaluated by Diagnosis and Curative Effect Standard for Symptom pattern of Traditional Chinese Medicine, which was much higher than 45.84% in the usual care group (H = 16.000, P < 0.001).

Conclusion: Both of the hand-ear acupuncture and standard acupuncture modes have beneficial and persistent effectiveness against cLBP compared with the usual care. Furthermore, hand-ear acupuncture is significantly more effective than the standardized acupuncture, especially in the long term.

Long noncoding RNA Crnde attenuates cardiac fibrosis via Smad3-Crnde negative feedback in diabetic cardiomyopathy.

FEBS J 2019 05 1;286(9):1645-1655. Epub 2019 Mar 1.

Department of Pharmacy, The General Hospital of Western Theater Command, Chengdu, China.

Diabetic cardiomyopathy (DCM)-ventricular dysfunction in the absence of underlying heart disease-is a common complication of diabetes and a leading cause of mortality associated with the disease. In DCM, cardiac fibrosis is the main cause of heart failure. Although it is well-established that the transforming growth factor-beta signaling pathway plays a part in inducing cardiac fibrosis in DCM, details of the molecular mechanism involved remain elusive. Therefore, it is crucial to study the gene reg;ulation of key signaling effectors in DCM-associated cardiac fibrosis. A recently emerged hotspot in the field of gene regulation is the role of long noncoding RNAs (lncRNAs). Recent evidence indicates that lncRNAs play a critical role in cardiac fibrosis; however, in DCM, the function of these regulatory RNAs have not been studied in depth. In this study, we identified a conserved cardiac-specific lncRNA named colorectal neoplasia differentially expressed (Crnde). By analyzing 376 human heart tissues, it was found that Crnde expression is negatively correlated with that of cardiac fibrosis marker genes. Moreover, Crnde expression was shown to be enriched in cardiac fibroblasts (CFs). Overexpression of Crnde attenuated cardiac fibrosis and enhanced cardiac function in mice with DCM. Further, in vitro experiments showed that Crnde negatively regulates the myofibroblast differentiation of CFs. The expression of Crnde was activated by SMAD family member 3 (Smad3), shedding light on the underlying molecular mechanism. Interestingly, Crnde also inhibited the transcriptional activation of Smad3 on target genes, thereby inhibiting the expression of myofibroblastic marker genes in CFs. Overall, our data provide valuable insights into the development of potential anti-cardiac fibrosis strategies centered on lncRNAs, for the treatment of DCM.

The Effect of Puerarin on Carotid Intima-media Thickness in Patients With Active Rheumatoid Arthritis: ARandomized Controlled Trial.

Clin Ther 2018 10 21;40(10):1752-1764.e1. Epub 2018 Sep 21.

Department of Traditional Chinese Medicine, Rheumatology Center of Integrated Medicine, Chengdu Military General Hospital, Chengdu, China. Electronic address:

Purpose: Cardiovascular and diabetic complications are the main causes of death in patients with rheumatoid arthritis (RA). Puerarin has potential protective effects against subclinical atherosclerosis and insulin resistance, but the clinical evidence is still not sufficient to draw definitive conclusions. Therefore, we performed the clinical trial to assess the effect of puerarin on carotid intima-media thickness (CIMT) in RA.

Methods: This is an open, controlled, randomized, and parallel-group comparison study of 119 patients with a definite diagnose of active RA. All 119 consecutive patients with RA receiving routine antirheumatic care were randomized to receive treatment with (n = 60; 16 males and 44 females; mean age, 52.97 years; 95% CI, 49.78-56.15 years) or without (n = 59; 17 males and 42 females; mean age, 54.05 years; 95% CI, 50.03-58.07 years) 400mg of puerarin. The effects of both interventions on CIMT, homeostasis model assessment of insulin resistance (HOMA-IR) value, and possible adverse events were assessed and compared at entry, 12 weeks, and 24 weeks. The collected data were processed and assessed using ANCOVA, paired t test, repeated-measure ANOVA, one-way ANOVA, Pearson's χ test, Fisher exact test, Kaplan-Meier survival analysis, Pearson correlation, and LOESS (locally weighted smoothing) regression analysis.

Findings: No significant adverse effects occurred concerning the use of puerarin, and both interventions were generally well tolerated in all the patients. A tiny but significant decrease of CIMT was observed in puerarin-treated patients at 24 weeks (-0.003 mm; 95% CI, -0.005 to -0.001vs 0.019 mm; 95% CI, -0.002 to 0.040; P < 0.001). At 24 weeks, insulin resistance was indicated with more pronounced improvement in the puerarin group versus the control group (homeostasis model assessment, -0.40; 95% CI, -0.47 to -0.33vs -0.05; 95% CI, -0.08 to -0.01; P < 0.001). Correlation analysis indicated an interaction between the parallel reductions in CIMT and insulin resistance in the puerarin group (r = 0.878, P < 0.001) but not in the control group.

Implications: In the study, 24 weeks of treatment with 400mg of puerarin exerted a significant effect against CIMT progression in patients with active RA, which may be associated with the improvement of insulin resistance. Puerarin holds promise as a drug candidate for the prevention and treatment of cardiometabolic comorbidities in patients with active RA. However, more strictly designed trials, such as double-blind and placebo-controlled trials, are still required. ClinicalTrials.gov identifier: NCT02254655.

Prognostic significance of preoperative neutrophil-to-lymphocyte ratio and platelet-to-lymphocyte ratio in patients with glioma.

EXCLI J 2018 28;17:505-512. Epub 2018 May 28.

Department of Pharmacy, Chengdu Military General Hospital, Chengdu 610083, People's Republic of China.

The neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) have been recognized as inflammatory markers and used as prognostic makers in various cancers. The present study sought to investigate the prognostic role of NLR and PLR in Chinese patients with glioma. Clinical data, including NLR, PLR and overall survival (OS), were collected from 112 patients who underwent surgery to treat primary glioma. Kaplan-Meier survival analysis as well as uni- and multivariate Cox regression were performed to examine potential associations of preoperative NLR and PLR with OS. Among all patients, mean NLR was 3.80±1.48 and mean PLR was 183.60±81.38. NLR increased with increasing WHO tumor grade (p < 0.05), but PLR did not (p > 0.05). Patients with NLR ≥ 4 had significantly shorter mean OS (20.75±7.68 months) than patients with NLR < 4 (26.91±7.50 months; p < 0.001). Similarly, patients with PLR ≥ LR had significantly shorter OS than patients with PLR < 200 (p = 0.007). Univariate Cox analysis identified the following parameters as significantly associated with worse OS: NLR (≥ 4), PLR (> 200), tumor size (≥ 5 cm), WHO grade (III/IV), and Karnofsky Performance Status (< 70). Multivariate analysis identified only NLR > 4 as an independent predictor of OS (HR 1.932, 95 % CI 1.011 to 3.694, p = 0.046). Our results suggest that at least in Chinese patients, increased preoperative NLR and PLR are associated with worse OS, and NLR may be an independent risk factor to identify glioma patients with poor prognosis. These results should be validated and extended in larger clinical studies.

Mangiferin Enhanced Autophagy via Inhibiting mTORC1 Pathway to Prevent High Glucose-Induced Cardiomyocyte Injury.

Front Pharmacol 2018 17;9:383. Epub 2018 Apr 17.

Department of Pharmacy, Chengdu Military General Hospital, Chengdu, China.

Mangiferin functions as a perfect anti-oxidative compound in the diabetic heart, however, the exact mechanism remains to be elucidated. Here, we show the cardioprotective effect of mangiferin under high glucose-induced cardiotoxic condition mainly contributed to enhanced autophagy via suppressing mTORC1 downstream signal transduction. Primary neonatal rat cardiomyocytes were cultured to detect myocytes injury, autophagy, and related signal transduction under different doses of glucose and mangiferin treatment. High glucose (30 mM) reduced autophagic flux, and increased myocyte apoptosis and death compared with normal glucose (5.5 mM) as determined by variation of autophagy markers LC3-II, p62, parkin, GFP-LC3, or mRFP-LC3 fluorescence puncta, cell viability, cleaved caspase 3, cleaved PARP apoptosis indices, reactive oxygen species (ROS), MAO, and PI death indices. Conversely, mangiferin inhibited hyperglycemia associated oxidative stress by reducing ROS, MAO, cleaved caspase 3, and cleaved PARP generation, reestablishing cell viability, mitochondrial membrane potential, and enhancing autophagic flux, thereby preventing myocytes from high glucose-induced toxicity. Furthermore, cardioprotection with mangiferin was potentially related to the decreased mTOR phosphorylation and suppression of mTORC1 downstream signaling pathway. These data indicated the valuable effects of mangiferin on regulation of cardiac autophagy and pointed to the promising utilization for hyperglycemia control.

Mangiferin attenuates blast-induced traumatic brain injury via inhibiting NLRP3 inflammasome.

Chem Biol Interact 2017 Jun 25;271:15-23. Epub 2017 Apr 25.

Department of Pharmacy, Chengdu Military General Hospital, No.270, Rongdu Avenue, Jinniu District, Chengdu 610083, Sichuan, People's Republic of China. Electronic address:

There is growing evidence that Mangiferin possess therapeutic benefit during neuroinflammation on various brain injury models due to its anti-inflammatory properties. It is reported that inflammatory plays a crucial role in the pathogenesis of secondary injury induced by the blast-induced traumatic brain injury (bTBI). However, the role of mangiferin in bTBI is yet to be studied. In our study, the potential effect of mangiferin in the duration of bTBI was examined first. Fortunately, the amelioration of cerebral cortex damage was found in rats suffering bTBI after mangiferin administration. Furthermore, the detail mechanism of mangiferin's beneficial actions in bTBI was also studied. The results revealed that mangiferin might alleviate brain damage in rats with bTBI by inhibiting the NOD-like receptor family, pyrin domain-containing 3 (NLRP3) inflammasome activation, which was accompanied by mangiferin's inhibition of oxidative stress and pro-inflammatory cytokines production. Therefore, this research allows us to speculate that, for first time, NLRP3 is involved in the anti-inflammatory effect of mangiferin in the cerebral cortex, and mangiferin could be a potential therapy drug for bTBI.

Effect of Sanhuangyilong decoction plus methotrexate on tumor necrosis factor alpha and interferon gamma in serum and synovial fluid in rheumatoid arthritis patients with symptom pattern of damp heat obstruction.

J Tradit Chin Med 2016 10;36(5):625-33

Objective: To investigate the effect of Sanhuangyilong decoction plus methotrexate (MTX) on Interferon gamma (IFN-γ) and tumor necrosis factor alpha (TNF-α) in the serum and synovial fluid of rheumatoid arthritis (RA) patients with damp-heat-obstruction symptom pattern, Sanhuangyilong decoction and the role of TNF-α and IFN-γ in the development of RA.

Methods: RA inpatients with damp-heat-obstruction symptom pattern (partly with knee joint effusion) were selected as the research subjects. Before the treatment, healthy subjects and osteoarthritis (OA) patients with knee joint effusion were assigned to the serum control group and the synovial fluid control group, respectively; during the treatment, RA patients with damp-heat-obstruction symptom pattern were divided into two groups: one is combined group that was administered Sanhuangyilong decoction plus MTX; the other group was MTX group that received MTX only. The expression levels of TNF-α and IFN-γ in the serum and synovial fluid were measured with enzyme-linked immunosorbent assay (ELISA) before and after the treatment, and the peripheral blood levels of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and disease activity score in 28 joints (DAS28) were determined.

Results: Before treatment, the serum levels of TNF-α and IFN-γ in the RA patients with dampheat- obstruction symptom pattern were higher than those in healthy control group (P < 0.05).The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those in the serum of the RA patients (P < 0.05). The expression levels of TNF-α and IFN-γ in the synovial fluid of the RA patients were higher than those of the synovial fluid of the osteoarthritis patients (P < 0.05). The expression of TNF-α and IFN-γ in the serum and synovial fluid of the RA patients had no correlation with the inflammatory activity index ESR, CRP, or DAS28 (P > 0.05). After 2 weeks of treatment, the expression level of TNF-α and IFN-γ in the combined group had increased, although the difference was not statistically significant (P > 0.05); in contrast, ESR, CRP, and DAS28 decreased, and the difference was statistically significant (P < 0.01). After 4 weeks of therapy, TNF-alpha and IFN-γ, ESR, CRP, and DAS28 in the combined group decreased compared with the before-treatment levels (P < 0.01). After 2 w of treatment, the differences in the TNF-α and IFN-γ expression levels in the combined group were not statistically significant (P > 0.05) compared with that in the MTX group, although there were statistically significant differences in the ESR, CRP, and DAS28 (P < 0.05). After 4 weeks of treatment, differences in TNF-α, IFN-γ, ESR, CRP, and DAS28 in the combined group compared with MTX group were statistically significant (P < 0.01).

Conclusion: TNF-α and IFN-γ might be involved in the development of RA. The RA patients with damp-heat-obstruction symptom pattern show better benefits from the treatment of Sanhuangyilong decoction plus MTX, and the treatment is superior to that of using MTX only.

Background: After receiving the 25 April 2015 Nepal earthquake relief mission, a fully self-sufficient Rescue Center of Trauma set up quickly in downtown Kathmandu by Chengdu Military Medical Team of PLA P. R. China.

Methods: The medical team consisted of 68 members and 40 tons of supplies, which was equivalent to a small hospital. The medical area and living area were constructed with tents. Operating areas were converted from eight simple bungalows. The main purpose of the Rescue Center of Trauma was to save those earthquake survivors who needed surgery.

Results: From 30 April to 10 May, 35 cases of orthopaedic internal fixation and external fixation operations were completed in the Rescue Center of Trauma. Surgery involved a total of 27 patients. All of the 27 orthopaedic surgery patients received treatment without any serious complications, including internal fixation failure, infection, amputation, limb deformities, limb dysfunction, or skin necrosis.

Conclusions: Trauma infection rates are usually higher after an earthquake. Due to poor conditions, implementation of orthopaedic surgery at a field hospital is limited due to a lack of blood, equipment, and drugs. Infection control remains a key determinant of the success of surgery. Effective measures to control infection include strict environmental disinfection, extending the sterilizing time of fixation devices and supplies, doubling the number and time of washing and disinfection, and rational use of antibiotics based on past experience.

Mangiferin suppressed advanced glycation end products (AGEs) through NF-κB deactivation and displayed anti-inflammatory effects in streptozotocin and high fat diet-diabetic cardiomyopathy rats.

Can J Physiol Pharmacol 2016 Mar 3;94(3):332-40. Epub 2015 Nov 3.

d Department of Traditional Chinese Medicine, Chengdu Military General Hospital, Chengdu, China.

Given the importance of the aggregation of advanced glycation end products (AGEs) and cardiac inflammation in the onset and progression of diabetic cardiomyopathy (DCM), our objective in this study was to demonstrate the cardioprotective effect of mangiferin, an antidiabetic and anti-inflammatory agent, on diabetic rat model. The DCM model was established by a high-fat diet and a low dose of streptozotocin. DCM rats were treated orally with mangiferin (20 mg/kg) for 16 weeks. Serum and left ventricular myocardium were collected for determination of inflammatory cytokines. AGEs mRNA and protein expression of nuclear factor kappa B (NF-κB) and receptor for AGEs (RAGE) in myocardium were assayed by real-time PCR and Western blot. ROS levels were measured by dihydroethidium fluorescence staining. NF-κB binding activity was assayed by TransAM NF-κB p65 ELISA kit. Chronic treatment with mangiferin decreased the levels of myocardial enzymes (CK-MB, LDH) and inflammatory mediators (TNF-α, IL-1β). Meanwhile, NF-κB is inhibited by the reduction of nuclear translocation of p65 subunit, and mangiferin reduced AGE production and decreased the mRNA and protein expression of RAGE in DCM rats. Our data indicated that mangiferin could significantly ameliorate DCM by preventing the release of inflammatory cytokines, and inhibiting ROS accumulation, AGE/RAGE production, and NF-κB nuclear translocation, suggesting that mangiferin treatment might be beneficial in DCM.

A contrast study of the traumatic condition between the wounded in 5.12 Wenchuan earthquake and 4.25 Nepal earthquake.

Chin J Traumatol 2015 ;18(3):157-60

Chengdu Military General Hospital, Chengdu 610083, China.

Purpose: 5.12 Wenchuan earthquake and 4.25 Nepal earthquake are of the similar magnitude, but the climate and geographic environment are totally different. Our team carried out medical rescue in both disasters, so we would like to compare the different traumatic conditions of the wounded in two earthquakes.

Methods: The clinical data of the wounded respectively in 5.12 Wenchuan earthquake and 4.25 Nepal earthquake rescued by Chengdu Military General Hospital were retrospectively analyzed. Then a contrast study between the wounded was conducted in terms of age, sex, injury mechanisms, traumatic conditions, complications and prognosis.

Results: Three days after 5.12 Wenchuan earthquake, 465 cases of the wounded were hospitalized in Chengdu Military General Hospital, including 245 males (52.7%) and 220 females (47.3%) with the average age of (47.6±22.7) years. Our team carried out humanitarian relief in Katmandu after 4.25 Nepal earthquake. Three days after this disaster, 71 cases were treated in our field hospital, including 37 males (52.1%) and 34 females (47.9%) with the mean age of (44.8±22.9) years. There was no obvious difference in sex and mean age between two groups, but the age distribution was a little different: there were more wounded people at the age over 60 years in 4.25 Nepal earthquake (p<0.01) while more wounded people at the age between 21 and 60 years in 5.12 Wenchuan earthquake (p<0.05). The main cause of injury in both disasters was bruise by heavy drops but 5.12 Wenchuan earthquake had a higher rate of bruise injury and crush injury (p<0.05) while 4.25 Nepal earthquake had a higher rate of falling injury (p<0.01). Limb fracture was the most common injury type in both disasters. However, compared with 5.12 Wenchuan earthquake, 4.25 Nepal earthquake has a much higher incidence of limb fractures (p<0.01), lung infection (p<0.01) and malnutrition (p<0.05), but a lower incidence of thoracic injury (p<0.05) and multiple injury (p<0.05). The other complications and death rate showed no significant differences.

Conclusion: Major earthquakes of the similar magnitude can cause different injury mechanisms, traumatic conditions and complications in the wounded under different climate and geographic environment.When an earthquake occurs in a poor traffic area of high altitude and large temperature difference, early medical rescue, injury control and wounded evacuation as well as sufficient warmth retention and food supply are of vital significance.

Effect of sanhuangwuji powder, anti-rheumatic drugs, and ginger-partitioned acupoint stimulation on the treatment of rheumatoid arthritis with peptic ulcer: a randomized controlled study.

J Tradit Chin Med 2015 Jun;35(3):273-80

Objective: To observe the efficacy and safety of oral sanhuangwuji powder, anti-rheumatic drugs (ARDs), and ginger-partitioned acupoint stimulation at zusanli (ST 36) on the treatment of rheumatoid arthritis (RA) complicated by peptic ulcer.

Methods: This prospective randomized controlled study included 180 eligible inpatients and outpatients randomly assigned to an ARD treatment (n.= 60), ginger-partitioned stimulation (n = 60), or combination treatment (n = 60). Patients assigned to the ARD group were given oral celecoxib, methotrexate, and esomeprazole. Patients assigned to the ginger-partitioned stimulation group were given ginger-partitioned acupoint stimulation at zusanli (ST 36) in addition to the ARDs. Patients in the combination treatment group were given oral sanhuangwuji powder, ginger-partitioned acupoint stimulation at susanli (ST 36), and ARDs. All patients were followed up for 2 months to evaluate clinical effects and safety. The study was registered in the World Health Organization database at the General Hospital of Chengdu Military Area Command Chinese People's Liberation Army (ChiCTR-TCC12002824).

Results: The combination treatment group had significantly greater improvements in RA symptoms, laboratory outcomes, and gastrointestinal symptom scores, compared with the other groups (P < 0.05). The peptic ulcer healing rate in the combination treatment group was significantly greater than that in the ARD treatment group (χ2= 16.875, P < 0.05) and the ginger-partitioned stimulation group (χ2= 6.171, P < 0.05).

Conclusion: Combination treatment with ginger-partitioned acupoint stimulation at zusanli (ST 36), oral sanhuangwuji powder, and ARDs had a better clinical effect for RA with complicated peptic ulcer, compared with ARD treatmentalone or in combination with ginger-partitioned acupoint stimulation.

Cinnamaldehyde prevents endothelial dysfunction induced by high glucose by activating Nrf2.

Cell Physiol Biochem 2015 5;36(1):315-24. Epub 2015 May 5.

Department of Cardiology, The First Affiliated Hospital, Chengdu Medical College, Chengdu, China.

Background/aims: It is well documented that hyperglycemia-induced oxidative stress is an important causative factor of endothelial dysfunction. Cinnamaldehyde (CA) is a key flavor compound in cinnamon essential oil that can enhance the antioxidant defense against reactive oxygen species (ROS) by activating NF-E2-related factor 2 (Nrf2), which has been shown to have a cardiovascular protective effect, but its role in endothelial dysfunction induced by high glucose is unknown.

Methods: Dissected male C57BL/6J mouse aortic rings and HUVECs were cultured in normal glucose(NG 5.5 mM) or high glucose(HG 30.0 mM) DMEM treatment with or without CA (10 µM).

Results: Treatment with CA protected the endothelium relaxation, inhibited ROS generation and preserved nitric oxide (NO) levels in the endothelium of mouse aortas treated with high glucose . CA up-regulated Nrf2 expression, promoted its translocation to the nucleus'and increased HO-1, NQO1, Catalase and Gpx1 expression under high glucose condition. The increased level of nitrotyrosine in HUVECs under high glucose was also attenuated by treatment with CA. Dihydroethidium (DHE) and DAF-2DA staining indicated that CA inhibited the ROS generation and preserved the NO levels in HUVECs, but these effects were reversed by Nrf2-siRNA in high glucose conditions.

Conclusion: Our results indicated that CA protected endothelial dysfunction under high glucose conditions and this effect was mediated by Nrf2 activation and the up-regulation of downstream target proteins. CA administration may represent a promising intervention in diabetic patients who are at risk for vascular complications.

Characterization of a novel orthoreovirus isolated from fruit bat, China.

BMC Microbiol 2014 Nov 30;14:293. Epub 2014 Nov 30.

Background: In recent years novel human respiratory disease agents have been described for Southeast Asia and Australia. The causative pathogens were classified as pteropine orthoreoviruses with a strong phylogenetic relationship to orthoreoviruses of bat origin.

Results: In this report, we isolated a novel Melaka-like reovirus (named "Cangyuan virus") from intestinal content samples of one fruit bat residing in China's Yunnan province. Phylogenetic analysis of the whole Cangyuan virus genome sequences of segments L, M and S demonstrated the genetic diversity of the Cangyuan virus. In contrast to the L and M segments, the phylogenetic trees for the S segments of Cangyuan virus demonstrated a greater degree of heterogeneity.

Conclusions: Phylogenetic analysis indicated that the Cangyuan virus was a novel orthoreovirus and substantially different from currently known members of Pteropine orthoreovirus (PRV) species group.

Phage-display library biopanning and bioinformatic analysis yielded a high-affinity peptide to inflamed vascular endothelium both in vitro and in vivo.

J Control Release 2014 Jan 14;174:72-80. Epub 2013 Nov 14.

Key Laboratory of Functional Proteomics of Guangdong Province, Department of Pathophysiology, Southern Medical University, 510515 Guangzhou, PR China. Electronic address:

Vascular inflammation is considered the primary pathological condition occurring in many chronic diseases. To detect the inflamed endothelium via imaging analysis or guide the drug to target lesions is therefore important for early diagnosis and treatment of vascular inflammatory diseases. In this study, we obtained a novel peptide NTTTH through high throughout biopanning and bioinformatic analysis. In vitro studies indicated that NTTTH homologs could especially target inflamed vascular endothelial cells, as imaging quantitative analysis indicated that the mean of integrated optical density (MIOD) and mean of stained area (MSA) were significantly higher versus control (P<0.05). In vivo studies showed that, after intravenous injection of enhanced green fluorescent protein (EGFP)-labeled NTTTH homologs into the lipopolysaccharide (LPS)-inflamed mice for 30min, NTTTH homologs were distributed in highly vascularized and inflamed organs like liver and kidney. As a control, little fluorescence could be detected in mice injected with EGFP alone. Cryosection showed that NTTTH homologs especially targeted inflamed vasculatures but not normal ones. We did not detect fluorescence signal in either normal or inflamed mice which were injected with EGFP alone. The results suggested the role of NTTTH homologs in guiding the targeted binding of EGFP to inflamed vasculature and the potential usage for imaging detection and drug delivery.

Scube regulates synovial angiogenesis-related signaling.

Med Hypotheses 2013 Nov 8;81(5):948-53. Epub 2013 Sep 8.

Rheumatology Center, PLA General Hospital of Chengdu Military Area Command, Chengdu, Sichuan Province, PR China; National TCM Rehab Center, PLA General Hospital of Chengdu Military Area Command, Chengdu, Sichuan Province, PR China; Key Laboratory of Functional Proteomics of Guangdong Province, Department of Pathophysiology, Southern Medical University, Guangzhou, Guangdong Province, PR China. Electronic address:

Angiogenesis is particularly driven in the synovial microenvironment of Rheumatoid arthritis (RA), and considered as the fundamental cause for the persistent injury and chronic damage. Therefore, exploring the pathomechanism of synovial angiogenesis may provide promising prospects for vascular-targeting treatment of RA. The noval family of Scube proteins is confirmed to overlap significantly in structure characterized by epidermal growth factor (EGF)-like domains and CUB (complement subcomponents C1r/C1s, Uegf, bone morphogenetic protein-1) domain. As secreted glycoprotein and peripheral membrane protein, Scube increases its serum level in response to stimuli of inflammation and hypoxia. In rheumatoid angiogenesis-related signaling system defined by hedgehog (Hh), transforming growth factor (TGF)β and bone morphogenetic protein 2 (BMP2), Scube1 and 2 antagonize BMP2 signaling, suppressing BMP2-induced phospho-Smad1/5/8 level in vivo. Scube3 functions as an endogenous TGFβ receptor ligand, increasing Smad2/3 phosphorylation, and thus upregulates target genes involved in angiogenesis. Via obligate assistance of Scube1 and 3, Scube2 plays a center role to recruit dually lipid-modified Hh transferred from Dispatched A (DispA), increasing Hh secretion by promoting its solubility. These findings support the hypothesis that Scube may regulate synovial angiogenesis may be the ideal vascular targets for anti-rheumatic treatment of RA.

Replication of british rheumatoid arthritis susceptibility Loci in two unrelated chinese population groups.

Clin Dev Immunol 2013 3;2013:891306. Epub 2013 Sep 3.

Department of Oncology, Chengdu Military General Hospital, Chengdu 610083, China.

Previous genome-wide association study by WTCCC identified many susceptibility loci of common autoimmune diseases in British, including rheumatoid arthritis (RA). Because of the genetic heterogeneity of RA, it is necessary to replicate these susceptibility loci in other populations. Here, three SNPs with strong RA association signal in the British were analyzed in Han Chinese, and two SNPs (rs6457617 and rs11761231) were genotyped in the test cohort firstly. The rs6457617 was significantly associated with RA in the test cohort. The individuals bearing the homozygous genotype CC had 0.39-fold risk than these bearing the wild-type genotype TT (P = 0.004, OR 0.39, [95% CI 0.21-0.74]). And the protective effect of allele C was confirmed in another validation cohort with 1514 samples (P genotye CC/TT = 5.9 ×  10(-10), OR 0.34, [95% CI 0.24-0.48]). The rs6457617 can be used as a tagSNP of HLA-DQA1∗03 which encoded MHC-II α chain. Since MHC restriction is important for primary T-cells in positive selection and negative selection stages, MHC protein polymorphisms may be implicated in shaping the T-cell repertoire, including the emergence of a T-cell clone involved in the inflammatory arthritis.

Mangiferin mitigates diabetic cardiomyopathy in streptozotocin-diabetic rats.

Can J Physiol Pharmacol 2013 Sep 22;91(9):759-63. Epub 2013 Aug 22.

Department of Pharmacy, Chengdu Military General Hospital, Chengdu, China.

The purpose of this study was to investigate the cardioprotective effect of mangiferin on diabetic cardiomyopathy (DCM). The DCM model was induced by a high-fat diet and a low dose of streptozotocin. We evaluated the characteristics of DCM by serial echocardiography, electron microscopy, histopathologic analysis of cardiomyocyte fibrosis area, and Western blot analysis of matrix metalloproteinase-2 (MMP-2) and MMP-9 expression. Rats with DCM showed severe left ventricular dysfunction and cardiac fibrosis. Mangiferin mitigated DCM and prevented the accumulation of myocardial collagen. These anatomic findings were accompanied by significant improvements in cardiac function. Based on these results, we conclude that mangiferin has a therapeutic effect on DCM and improves cardiac function.

Histomorphological researches on large porous hydroxyapatite cylinder tubes with polylactic acid surface coating in different nonskeletal sites in vivo.

J Biomed Mater Res A 2012 May 18;100(5):1203-8. Epub 2012 Feb 18.

Department of Orthopedics, 452nd Hospital of Chinese PLA, Chengdu, Sichuan, People's Republic of China.

Porous hydroxyapatite (HA) ceramic cylinder tubes coated with polylactic acid on the exposed surfaces were implanted in four nonskeletal sites (omentum, peritoneum, vastus lateralis, and side of femur). Six months postoperatively, proper amount of Chinese ink was injected to dye the implanting areas. Decalcified and nondecalcified sections were observed under inverted microscope. The results showed that the soft tissues around the HA cylinder tubes in peritoneum, vastus lateralis, and side of femur groups appeared visible black. Some small blacked vascular architectures were also discernible. However in omentum group, only small number of blacked vessels existed. Histological observations indicated that vascularization and ossification occurred in peritoneum, vastus lateralis, and side of femur groups. In omentum group, there was no any sign of vascularization and ossification. A conclusion could be made in this study that excepting bones and muscles, parietal peritoneum could serve as a potential spot for culturing histoengineering hydroxyapatite (HA)-polylactic acid (PLA) ceramic bone substitutes.

J Tradit Chin Med 2003 Sep;23(3):163-7

Department of Endocrine, First Hospital, Tianjin College of Traditional Chinese Medicine, Tianjin 300193.

Unlabelled: In order to observe the therapeutic effects of Huatan Yigan Decoction ([symbol: see text] Decoction for resolving phlegm and replenishing the liver) on antidiabetic-induced hepatopathy, 129 cases were divided into two groups, 72 cases in the treatment group were administrated with Huatan Yigan Decoction and 57 cases in the control group with the liver-protecting drugs. Their liver function, plasma prothrombin time (PT), blood urea nitrogen and symptoms of the patients before and after treatment were observed during the three therapeutic courses.

Results: The total effective rate and cured rate of the treatment group manifested an obvious difference in comparison with those of the control group (P < 0.05 or P < 0.01). Even though the liver function, blood urea nitrogen (BUN) and symptoms in both groups were improved markedly, these indicators in the treatment group were improved more markedly than those in control group (P < 0.01). No adverse effect was found during the treatment.

Conclusion: Huatan Yigan Decoction shows a repair action on hepatic injury.
