Background: Xin-Ji-Er-Kang (XJEK) as a herbal formula of traditional Chinese medicine (TCM) has shown the protective effects on myocardial function as well as renal function in mouse models of myocardial infarction.

Hypothesis/purpose: We investigated the effects of XJEK on cardiovascular- and renal-function in a heart failure mouse model induced by high salt (HS) and the associated mechanisms.

Study Design: For the purpose of assessing the effects of XJEK on a hypertensive heart failure model, mice were fed with 8% high salt diet. XJEK was administered by oral gavage for 8 weeks. Cardiovascular function parameters, renal function associated biomarkers and XJEK's impact on renin-angiotensin-aldosterone system (RAAS) activation were assessed. To determine the underlying mechanism, the calpain1/junctophilin-2 (JP2)/sarcoplasmic reticulum Ca ATPase (SERCA2a) pathway was further studied in AC16 cells after angiotensin II-challenge or after calpastatin small interfering RNA (siRNA) transfection.

Results: Mice on HS-diet exhibited hypertensive heart failure along with progressive kidney injury. Similar to fosinopril, XJEK ameliorated hypertension, cardiovascular-and renal- dysfunction in mice of HS-diet group. XJEK inhibited HS-induced activation of RAAS and reversed the abnormal expression pattern of calpain1and JP2 protein in heart tissues. XJEK significantly improved cell viability of angiotensin II-challenged AC16 cells. Moreover, XJEK's impact on calpain1/JP2 pathway was partly diminished in AC16 cells transfected with calpastatin siRNA.

Conclusion: XJEK was found to exert cardiovascular- and renal protection in HS-diet induced heart failure mouse model. XJEK inhibited HS-diet induced RAAS activation by inhibiting the activity and expression of calpain1 and protected the junctional membrane complex (JMC) in cardiomyocytes.

Effects of oligomeric grape seed proanthocyanidins on L-NAME-induced hypertension in pregnant mice: Role of oxidative stress and endothelial dysfunction.

Phytother Res 2018 Sep 31;32(9):1836-1847. Epub 2018 May 31.

Department of Pharmacology, Basic Medical College, Anhui Medical University, Hefei, 230032, China.

The aim of this study was to investigate the effects of Grape Seed Proanthocyanidins (GSP) on Nω-Nitro-L-arginine methyl ester-induced hypertension in pregnant mice. Fifty Kunming mice were randomized into control, control + GSP, model, and model + GSP. Three weeks later, the artery systolic blood pressure was examined and the related pathological changes were detected. Aorta relaxation function was assessed by aorta ring apparatus. Blood urea nitrogen and serum creatinine were measured by an automatic biochemistry analyzer. Colorimetric analysis, enzyme-linked immunosorbent assay, immunofluorescence, and western blot were applied to detect related indicator in serum, cardiac, and kidney tissues. The results showed that GSP treatment for 3 weeks could improve cardiovascular and kidney remodeling indexes and decrease blood urea nitrogen and serum creatinine content in serum, as well as could ameliorate oxidative stress status and endothelial dysfunction. Therefore, it is for the first time found that GSP exerts protective effect against Nω-Nitro-L-arginine methyl ester-induced hypertension in pregnant mice, which provided a theoretical basis for potential application in the clinic.

Objective: To investigate the role of ROG, GATA3 and T-bet in the progression of chronic hepatitis B (CHB).

Methods: The mRNA levels of ROG, GATA3 and T-bet in peripheral blood mononuclear cells (PBMCs) from 135 patients with CHB (including 45 mild cases, 42 moderate cases, and 48 severe cases) and 15 healthy control subjects were detected by real-time quantitative PCR.

Results: The levels of T-bet mRNA in the PBMCs were significantly higher in CHB patients than in the healthy controls (P<0.05), and also differed significantly between the 3 groups of CHB patients (P<0.05). ROG mRNA levels were significantly higher in severe cases of CHB than in the healthy controls and mild and moderate CHB cases (P<0.05), but were similar among the latter 3 groups (P>0.05). The mRNA level of GATA3 in the PBMCs were significantly higher in moderate and severe CHB cases than in the healthy controls and mild CHB cases (P<0.05). The T-bet/GATA3 ratio was significantly greater in the 3 CHB groups than in the control group (P<0.05) but comparable between the 3 CHB groups (P>0.05). ROG levels were not correlated with GATA3 levels or T-bet/GATA3 ratio in the CHB cases.

Conclusions: The mRNA levels of ROG, GATA3 and T-bet in the PBMCs are obviously up-regulated in CHB patients and these 3 genes may participate in the progression of CHB. ROG plays an important role in correcting and maintaining the new balance of Th1/Th2.

Influence of chronic HBV infection on superimposed acute hepatitis E.

World J Gastroenterol 2013 Sep;19(35):5904-9

Si-Hong Cheng, Li Mai, Feng-Qin Zhu, Xing-Fei Pan, Hai-Xia Sun, Hong Cao, Xin Shu, Wei-Min Ke, Gang Li, Qi-Huan Xu, Department of Infectious Diseases, the Third Affiliated Hospital of Sun Yat-sen University, Guangzhou 510630, Guangdong Province, China.

Aim: To investigate the influence of chronic hepatitis B virus (HBV) infection [based on the status of hepatitis B e antigen (HBeAg), HBV DNA, and cirrhosis] on superimposed acute hepatitis E.

Methods: A total of 294 patients were recruited from the Department of Infectious Diseases of the Third Affiliated Hospital, Sun Yat-sen University, from January 2003 to January 2012. The patients were classified into two groups: an HBV + hepatitis E virus (HEV) group (a group with chronic HBV infection that was superinfected with acute hepatitis E, n = 118) and an HEV group (a group with acute hepatitis E, n = 176). We retrospectively analyzed and compared the clinical features of the two groups. Statistical analyses were performed using the χ(2) test or Fisher's exact test for categorical variables and the Student's t test for continuous variables. A P value < 0.05 was considered statistically significant.

Results: The peak values of prothrombin time, serum total bilirubin, and Model for End-Stage Liver Disease scores were significantly higher in the HBV + HEV group. More patients in the HBV + HEV group had complications (39.8% vs 16.5%, P = 0.000) and developed liver failure (35.6% vs 8.5%, P = 0.000). Additionally, the mortality of the HBV + HEV group was significantly higher (20.3% vs 7.4%, P = 0.002). Further analysis of the HBV + HEV group showed that there were no significant differences in complication occurrence, liver failure incidence, or mortality between patients with different HBeAg and HBV DNA statuses. However, in patients with underlying cirrhosis, complication occurrence and liver failure incidence significantly increased. In total, 12.7% of the patients in the HBV + HEV group received anti-HBV treatment, but this therapy failed to reduce mortality in patients who developed liver failure.

Conclusion: The presence of underlying cirrhosis in chronic HBV infection results in more severe clinical outcomes with superimposed acute hepatitis E. Anti-HBV treatment cannot improve the prognosis of liver failure caused by HBV-HEV superinfection.
