Assessing perceived quality of primary care under hospital-township health centre integration: A cross-sectional study in China

Since the new round of health care reform in 2009, the vertical integration of hospitals and primary health institutions has become widely implemented in China as an efficient method for improving quality of primary care. This study aimed to answer the following questions: (a) What is the perceived quality of township health centres (THCs) under integration? (B) What differences could be observed among the three typical integration models, namely, private hospital-THC integration, public hospital-THC integration, and loose collaboration? Two rounds of cross-sectional surveys were conducted from November 2016 to June 2018. The Chinese version of the Primary Care Assessment Tool was used to evaluate perceived quality of sample THCs, and 1118 adult patients were interviewed in total. Multiple linear regressions were employed to compare the quality scores between two survey rounds and among different integration models after controlling for potential confounders. The results revealed that the quality of care significantly improved under private hospital-THC integration as observed by comparing two survey rounds, while no change or slight changes were observed in the other two models. The difference observed among the three models was that the perceived quality of THCs integrated with private hospitals was worse than that of THCs integrated with public hospitals and THCs under loose collaboration, while no significant difference was observed between public hospital-THC integration and loose collaboration. Increased attention should be given to highlighting the tight integration between hospitals and THCs and the different roles played by private and public hospitals in the current reform.     

模拟诊疗在留学生心血管内科实习带教中的应用研究

目的　探讨模拟诊疗在留学生心血管内科实习带教中的应用效果。方法　将35名留学生随机编号，分成试验组和对照组。试验组18名学生分成3组（每组6名）进行模拟诊疗教学，对照组17名学生进行常规实习。通过填写评价单和相关的临床能力测试对两组教学效果进行评价。选用SPSS 19.0软件进行t检验。结果　参与模拟诊疗教学的留学生均希望在各科实习中多采用此方法。在临床能力测试方面，试验组学生在病史采集[（22.16±2.17）vs.（20.33±2.03）]、体格检查[（23.05±1.79）vs.（19.78±2.05）]及回答问题[（23.50±1.47）vs.（19.56±1.92）]方面均优于对照组，差异有统计学意义（P<0.05）。但是在病历书写方面，两组差异无统计学意义（P>0.05）。结论　利用高仿真的模拟诊疗教学手段，弥补了留学生在实习期间不能充分接触患者的缺陷，有助于提高其临床操作技能、增强医患沟通能力等医学职业素养。     

Clinical assessment of synbiotics for treating chronic kidney disease: A protocol for systematic review and meta-analysis

Background:This research aims to evaluate the efficacy and safety of synbiotics for treating chronic kidney disease.Methods:Related articles written in English were sourced from EMBASE, PubMed, Cochrane Library, and China National Knowledge Infrastructure. These articles were used in the evaluation of the effect of synbiotics for treating chronic kidney disease. The extent of the relationship was assessed by calculating the pooled risk ratio, mean differences or standardized mean difference along with the equivalent 95% confidence intervals. The risk of bias introduced through each study was considered by adopting the Cochrane Risk of Bias Tool. Suitable statistical research methods were utilized for the synthesis of the data. The RevMan 5.3 software was used to conduct all statistical analysis.Results:The final results of the current study is due to be included in a peer-reviewed journal.Conclusion:The final remarks of the current study will be useful evidence for determining whether synbiotics is an effective and safe therapeutic method for treating chronic kidney disease.OSF registration number:DOI 10.17605/OSF.IO/UASF4 (https://osf.io/uasf4/).     

Dietary citrus and/or its extracts intake contributed to weight control: Evidence from a systematic review and meta‐analysis of 13 randomized clinical trials

Randomized controlled trials, being published in English and investigating the associations of at least 4 weeks intervention of citrus and/or its extracts on weight loss among adults, were searched from PubMed, Web of Science, Scopus, and Cochrane by June 2019 to conduct a meta‐analysis. Thirteen articles, including 921 participants, were selected and evaluated by modified Jadad scale. Pooled results by the random‐effects model showed that citrus and/or its extracts administration significantly reduced 1.280 kg body weight (95% CI: ?1.818 to ?0.741, p = 0.000, I² = 81.4%), 0.322 kg/m² BMI (95% CI: ?0.599 to ?0.046, p = 0.022, I² = 87.0%), 2.185 cm WC (95% CI: ?3.804 to ?0.566, p = 0.008, I² = 98.3%), and 2.137 cm HC (95% CI: ?3.775 to ?0.500, p = 0.011, I² = 96.2%), respectively, but no significantly decreased effects on WHR and body fat were observed. Subgroup analysis deduced the different effects of study location, intervention duration on body weight associated indices. No publication bias was observed. Our meta‐analysis supported the beneficial effects of citrus and/or its extracts supplement on body weight control, and future well‐designed studies are required to firmly establish the clinical efficacy of citrus and/or its extracts intervention on body weight.     

探讨氨甲环酸在老年股骨转子间骨折围手术期应用安全性及有效性分析
