Comparative prospective randomized study of minimally invasive transpiriformis approach versus conventional posterolateral approach in total hip arthroplasty as measured by biology markers.

Int Orthop 2021 07 27;45(7):1707-1717. Epub 2021 May 27.

Department of Orthopedics, The Third Hospital of Mianyang, Sichuan Mental Health Center, No. 190 The East Jiannan Road, Mianyang, 621000, China.

Background: Minimally invasive surgery is becoming increasingly common, but evidence of the advantages of the minimally invasive transpiriformis approach in total hip arthroplasty is limited. Therefore, our single-centre randomized controlled trial evaluated the benefits of this approach versus the posterolateral approach.

Methods: Forty-nine patients undergoing the minimally invasive transpiriformis approach and 57 patients undergoing the posterolateral approach total hip arthroplasty were analyzed. The operative time, length of hospital stay, incision length, and peri-operative data related to the surgery were recorded. In both groups, serum CRP, IL-6, HGb, Hct, MB, CK-MB, and CK levels, Harris hip scores, and VAS scores were recorded.

Results: Patients who underwent the minimally invasive transpiriformis approach had a smaller surgical incision (9.10 ± 0.94 vs. 15.56 ± 1.20 cm, P = 0.00) and shorter hospital stay (6.20 ± 1.54 vs. 12.26 ± 2.97 days, P = 0.00) than those who underwent the posterolateral approach. Serum levels of CRP, IL-6, MB, CK-MB, and CK were also lower. According to the Harris hip score, the minimally invasive transpiriformis group showed significant improvement at one week and one month after surgery.

Conclusion: Compared to the posterolateral approach, the minimally invasive transpiriformis approach for total hip arthroplasty provided rapid functional recovery, elicited a significantly reduced post-operative inflammatory response, and caused less muscle damage.

Newly graduated nurses' perceptions of work environment: A cross-sectional study in China.

Int J Nurs Pract 2021 Apr 10:e12929. Epub 2021 Apr 10.

Nursing Department, The First Affiliated Hospital of Kunming Medical University, Kunming, China.

Aim: To assess the attitudes of newly graduated nurses in China toward their work environment and identify the factors affecting their perception.

Background: Newly graduated nurses are the primary supply to cover the nursing shortage, but their stressful transition into clinical work has contributed to high turnover for decades. Although serving as a source of stress, the work environment can also be a source of support for new nurses.

Methods: A total of 2361 new nurses at 31 tertiary hospitals in 20 provinces were surveyed from June to November 2018, using the Chinese version of the Practice Environment Scale-Nursing Work Index. Basic information and their perception about work environment were collected.

Results: New nurses rated their work environment with an overall score of 84.67 (12.85). Multiple linear regression identified that education level, monthly income, hospital type and location, participation (or not) in standardized training programmes and having (or not) a mentor/preceptor were factors significantly associated with their perception of the work environment.

Conclusion: The perception of newly graduated nurses in China was mainly positive overall. Nursing managers may take full advantage of factors affecting the perception of work environment to support newly graduated nurses better, to help their retention and transition.

Summary Statement: What is already known about the topic? Newly graduated nurses experience transition shock at the beginning of their work. Supportive work environments can help successful transition. What this paper adds? Newly graduated nurses are not fully supported in their work environment. Staffing and resource inadequacy were the poorest environmental factors. Residency programmes had the most impact on the perceptions of newly graduated nurses about their work environment.

Implications For Nursing Practice: These results can guide nursing managers to support the newly graduated nurses better in their transition process, thus helping retention of nursing human resource.

Tranexamic acid safely reduces hidden blood loss in patients undergoing intertrochanteric fracture surgery: a randomized controlled trial.

Eur J Trauma Emerg Surg 2020 May 15. Epub 2020 May 15.

Department of Orthopedics, The Third Hospital of Mianyang, Sichuan Mental Health Center, No. 190 The East Jiannan Road, Mianyang, 621000, China.

Purpose: To investigate the efficacy and safety of intravenous tranexamic acid (IV-TXA) in patients undergoing intertrochanteric fracture surgery.

Methods: A total of 122 patients were included in this double-blinded trial and equally randomized to receive 1 g of IV-TXA or normal saline 10 min before incision and 3 h later. The primary efficacy outcome was calculated hidden blood loss (HBL). The secondary efficacy outcome was allogeneic erythrocyte transfusion rate during hospitalization. Safety outcome was a composite of thromboembolic events including deep venous thrombosis (DVT) up to 90 days. A meta-analysis combining this study with previous randomized controlled trials in hip fracture surgery (total sample size: 1112 patients) was also conducted.

Results: The mean HBL in TXA group (640.96 ± 421.63 ml) was significantly lower than that in placebo group (1010.11 ± 398.96 ml, P < 0.001). The rate of erythrocyte transfusions was 29.5% in TXA group and 60.7% in placebo group (P = 0.001). The incidence of thromboembolic events at 90 days was 4.9% in TXA group and 1.6% in placebo group (P = 0.619). The updated meta-analysis showed that IV-TXA significantly reduced erythrocyte transfusion in hip fracture surgery (risk ratio 0.60, 95% confidence intervals 0.53-0.68), and IV-TXA caused no increased risk of thromboembolic events (risk difference 0.01, 95% confidence intervals - 0.02-0.04).

Conclusion: IV-TXA could effectively reduce the HBL and allogeneic erythrocyte transfusion requirements in patients undergoing intertrochanteric fracture surgery without an increase of thromboembolic events including DVT.

Trial Registration: Clinical trials: safety and efficiency of tranexamic acid in hip fracture patients. Date of registration: August 31, 2018.

Pichia kudriavzevii retards fungal decay by influencing the fungal community succession during cherry tomato fruit storage.

Food Microbiol 2020 Jun 16;88:103404. Epub 2019 Dec 16.

State Key Laboratory of Food Nutrition and Safety, Key Laboratory of Food Nutrition and Safety, Ministry of Education of China, College of Food Engineering and Biotechnology, Tianjin University of Science and Technology, Tianjin, 300457, PR China. Electronic address:

In this study, P. kudriavzevii was isolated and identified as an effective antagonistic yeast, which could significantly inhibit the rotting rate, weight loss, and delay the color change, with no effect on total soluble solids (TSS), titratable acid (TA), or firmness during cherry tomato storage. High-throughput sequencing was used to survey the effect of P. kudriavzevii on fungal community throughout cold storage. The results showed that the biological succession of predominant pathogens was disrupted by P. kudriavzevii. The abundance of Botrytis and Alternaria was higher in the control than upon P. kudriavzevii treatment at 28 d, but some yeast genera such as Naganishia, Wickerhamomyces, and Cutaneotrichosporon at 14 d, Pichia and Sporidiobolus at 21 d, and Cystofilobasidium at 28 d, had relatively higher abundances in P. kudriavzevii treatments than the control. Oddly, as an antagonist agent, P. kudriavzevii was not the dominant population, indicating that altering the course of succession of the fungal community may be an effective mechanism of antagonistic yeast. Furthermore, the total network correlation analysis of fungal community revealed that the community development was more dependent on similarities in function than on taxonomic relationships.

Is intravenous tranexamic acid effective and safe during hip fracture surgery? An updated meta-analysis of randomized controlled trials.

Arch Orthop Trauma Surg 2019 Jul 14;139(7):893-902. Epub 2019 Jan 14.

Department of Orthopedics, The Third Hospital of Mianyang (Sichuan Mental Health Center), No. 190 The East Jiannan Road, Mianyang, 621000, China.

Introduction: The efficacy and safety of intravenous (IV) tranexamic acid (TXA) during hip fracture surgery remain controversial. This meta-analysis aimed to assess the efficacy of IV-TXA administration during hip fracture surgery for reducing the transfusion requirement and blood loss as well as its safety regarding the risk of thrombolysis.

Materials And Methods: PubMed, EMBASE, Web of Science, and the Cochrane Library Database were systematically searched for randomized controlled trials (RCTs) that focused on the efficacy and safety of IV-TXA in patients during hip fracture surgery. The primary outcome was the transfusion requirement. Secondary outcomes included total blood loss (TBL), deep vein thrombosis (DVT), and total thromboembolic events (TTEs). Risk ratio (RR), risk difference (RD), and mean difference (MD) for dichotomous and continuous data outcomes were determined from the meta-analysis. Data were analyzed using Rev Man 5.3.

Results: Altogether, 11 RCTs were included (total sample size 892 patients). IV-TXA significantly reduced the transfusion requirement [RR 0.60, 95% confidence interval (CI) 0.38-0.93, P = 0.02] and TBL (MD 326.64 ml, 95% CI - 462.23 to - 191.06, P < 0.00001) vs. cosntrol group. IV-TXA caused no increased risk of DVT (RD 0.02, 95% CI - 0.01 to 0.04, P = 0.13) or TTEs (RD 0.02, 95% CI - 0.01 to 0.05, P = 0.12).

Conclusion: Available evidence indicates that IV-TXA efficaciously reduces TBL and transfusion requirements during hip fracture surgery without significantly increasing the risk of TTEs including DVT.

Highly Sensitive p + n Metal Oxide Sensor Array for Low-Concentration Gas Detection.

Sensors (Basel) 2018 Aug 17;18(8). Epub 2018 Aug 17.

State Key Laboratory of Chemical Resource Engineering, Beijing University of Chemical Technology, North Third Ring Road 15, Beijing 100029, China.

Nowadays, despite the easy fabrication and low cost of metal oxide gas sensors, it is still challenging for them to detect gases at low concentrations. In this study, resistance-matched p-type Cu₂O and n-type Ga-doped ZnO, as well as p-type CdO/LaFeO₃ and n-type CdO/Sn-doped ZnO sensors were prepared and integrated into p + n sensor arrays to enhance their gas-sensing performance. The materials were characterized by scanning electron microscopy, transmittance electron microscopy, and X-ray diffractometry, and gas-sensing properties were measured using ethanol and acetone as probes. The results showed that compared with individual gas sensors, the response of the sensor array was greatly enhanced and similar to the gas response product of the p- and n-type gas sensors. Specifically, the highly sensitive CdO/LaFeO₃ and CdO/Sn-ZnO sensor array had a high response of 21 to 1 ppm ethanol and 14 to 1 ppm acetone, with detection limits of <0.1 ppm. The results show the effect of sensor array integration by matching the two sensor resistances, facilitating the detection of gas at a low concentration.

Polychlorinated biphenyls and polybrominated diphenylethers in soils from planted forests and adjacent natural forests on a tropical island.

Environ Pollut 2017 Aug;227:57-63

State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China. Electronic address:

Transformation from natural forests to planted forests in tropical regions is an expanding global phenomenon causing major modifications of land cover and soil properties, e.g. soil organic carbon (SOC). This study investigated accumulations of POPs in soils under eucalyptus and rubber forests as compared with adjacent natural forests on Hainan Island, China. Results showed that due to the greater forest filter effect and the higher SOC, the natural forest have accumulated larger amounts of POPs in the top 20 cm soil. Based on correlation and air-soil equilibrium analysis, we highlighted the importance of SOC in the distribution of POPs. It is assumed that the elevated mobility of POPs in the planted forests was caused by greater loss of SOC and extensive leaching in the soil profile. This suggests that a better understanding of global POPs fate should take into consideration the role of planted forests.

Elevated mobility of persistent organic pollutants in the soil of a tropical rainforest.

Environ Sci Technol 2015 Apr 27;49(7):4302-9. Epub 2015 Mar 27.

†State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China.

Semivolatile persistent organic pollutants (POP) are bioaccumulative and toxic contaminants. Their global distribution depends on source distribution, atmospheric transport, degradation, and the exchange with ocean and land surfaces. Forests are crucial terrestrial reservoirs due to the commonly envisaged high capacity of their surface soils to store and immobilize airborne contaminants bound to soil organic matter. Our results show that POPs can be unexpectedly mobile in the soil of a tropical rainforest due to fast litter turnover (leading to rapid POP transfer to the subsoil) and leaching rates exceeding degradation rates especially for more hydrophobic congeners. Co-transport in association with leaching fine particulate and dissolved organic matter appears as a relevant driver of this PCB export. A markedly different distribution pattern is displayed in this soil in comparison to soils of colder environments with lower overall storage capacity. These findings show that biogeochemistry of organic matter degradation and weathering can influence POP soil fate. Because tropical forests represent 60% of the global terrestrial productivity, the highlighted dynamics might have an implication for the general distribution of these contaminants.

Spatial distribution of old and emerging flame retardants in Chinese forest soils: sources, trends and processes.

Environ Sci Technol 2015 Mar 19;49(5):2904-11. Epub 2015 Feb 19.

State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences , Guangzhou 510640, China.

The levels and distribution of polybrominated diphenylethers (PBDEs), novel brominated flame retardants (NBFRs) and Dechlorane Plus (DP) in soils and their dependence on environmental and anthropological factors were investigated in 159 soil samples from 30 background forested mountain sites across China. Decabromodiphenylethane (DBDPE) was the most abundant flame retardant (25-18,000 pg g(-1) and 5-13,000 pg g(-1) in O-horizon and A-horizon, respectively), followed by BDE 209 (nd-5900 pg g(-1) and nd-2400 pg g(-1) in O-horizon and A-horizon, respectively). FRs distributions were primarily controlled by source distribution. The distributions of most phasing-out PBDEs, DP isomers and TBPH were in fact correlated to a population density-based index used as proxy of areas with elevated usage and waste of FR containing products. High concentrations of some NBFRs were however observed in industrialized regions and FR manufacturing plants. Strongly positive correlations were observed between PBDEs and their replacement products suggesting similar emission pattern and environmental behavior. Exposure of mineral subsoils depended on precipitations driving leaching of FRs into the soil core. This was especially evident for some emerging BFRs (TBE, TBPH, and TBB etc.) possibly indicating potential for diffuse groundwater contamination.

Does an analysis of polychlorinated biphenyl (PCB) distribution in mountain soils across China reveal a latitudinal fractionation paradox?

Environ Pollut 2014 Dec 13;195:115-22. Epub 2014 Sep 13.

State Key Laboratory of Organic Geochemistry, Guangzhou Institute of Geochemistry, Chinese Academy of Sciences, Guangzhou 510640, China. Electronic address:

Organic and mineral soil horizons from forests in 30 mountains across China were analysed for polychlorinated biphenyl (PCB). Soil total organic carbon (TOC) content was a key determinant of PCB distribution explaining over 90% of the differences between organic and mineral soils, and between 30% and 60% of the variance along altitudinal and regional transects. The residual variance (after normalization by TOC) was small. Tri- to tetra-CB levels were higher in the South in relation to high source density and precipitation. Heavier congeners were instead more abundant at mid/high-latitudes where the advection pattern was mainly from long range transport. This resulted in a latitudinal fractionation opposite to theoretical expectations. The study showed that exposure to sources with different characteristics, and possibly accumulation/degradation trends of different congeners in soils being out-of-phase at different latitudes, can lead to an unsteady large scale distribution scenario conflicting with the thermodynamic equilibrium perception.
