[Network Meta-analysis of oral Chinese patent medicine in adjuvant treatment of rotavirus gastroenteritis in children].

This study aimed to evaluate the efficacy and safety of various oral Chinese patent medicines in the adjuvant treatment of rotavirus gastroenteritis(RVGE) in children based on network Meta-analysis. Randomized controlled trial(RCT) of oral Chinese patent medicine in the adjuvant treatment of RVGE in children was retrieved from the databases such as CNKI, Wanfang, VIP, SinoMed, PubMed, Cochrane Library, EMbase, and Web of Science from database inception to October 22, 2022. The quality of the included RCT was evaluated according to the Cochrane risk-of-bias tool, and the data were analyzed by RevMan 5.4 and Stata 16 software. Sixty-three RCTs were included, with 11 oral Chinese patent medicines involved, including Xingpi Yanger Granules, Weichang'an Pills, Qiuxieling Mixture, Erxieting Granules, and Changyanning Granules/Syrup. The results of the network Meta-analysis showed that in terms of clinical total effective rate, the top 3 optimal interventions were Changyanning Granules/Syrup, Xiaoer Guangpo Zhixie Oral Liquid, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the anti-diarrheal time, the top 3 optimal interventions were Shenling Baizhu Granules, Qiuxieling Mixture, and Shuangling Zhixie Oral Liquid combined with conventional western medicine. In terms of the antiemetic time, the top 3 optimal interventions were Changyanning Granules/Syrup, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of the antipyretic time, the top 3 optimal interventions were Shenling Baizhu Granules, Xiaoer Shuangjie Zhixie Granules, and Qiuxieling Mixture combined with conventional western medicine. In terms of the negative conversion rate of rotavirus, the top 3 optimal interventions were Xingpi Yanger Granules, Erxieting Granules, and Cangling Zhixie Oral Liquid combined with conventional western medicine. In terms of reducing creatine kinase isoenzyme MB(CK-MB) level, the top 3 optimal interventions were Weichang'an Pills, Xingpi Yanger Granules, and Xiaoer Shuangjie Zhixie Granules combined with conventional western medicine. In terms of adverse reactions, no se-rious adverse reactions were reported in all studies. Oral Chinese patent medicines in the adjuvant treatment of children with RVGE have their own advantages, Specifically, Changyanning Granules/Syrup + conventional western medicine focuses on improving the clinical total effective rate and shortening the antiemetic time, Shenling Baizhu Granules + conventional western medicine on shortening the anti-diarrheal time and antipyretic time, Xingpi Yanger Granules + conventional western medicine on improving the negative conversion rate of rotavirus, and Weichang'an Pills + conventional western medicine on reducing the CK-MB level. Limited by the quantity and quality of literature included in this study, the results need to be verified by high-quality RCT with a larger sample size.

AIDS discrimination in junior college students and the effect of AIDS knowledge on discrimination / 中国学校卫生

Objective@#To analyze the situation of AIDS knowledge and discrimination among freshmen in Chengdu city, and to explore possible effects of AIDS knowledge on discrimination.@*Methods@#A cluster random sampling was employed to investigate 1 053 college students from 11 universities in Chengdu about their HIV/AIDS knowledge and discrimination. The scores of AIDS knowledge and discrimination of students with different characteristics were analyzed, and the influence path of AIDS knowledge on AIDS discrimination were further analyzed based on different peer relationships.@*Results@#The total scores of AIDS knowledge was negatively correlated to AIDS discrimination( r s =-0.13, P <0.01). After adjusting for confounding factors, the total score of AIDS knowledge was associated with the total score of AIDS discrimination( β =-0.12, P <0.01). AIDS knowledge played a role in AIDS discrimination in intimate, general and unfamiliar peer relationships, with standardized path coefficients of -0.20, -0.24 and -0.18 respectively( P <0.01).@*Conclusion@#AIDS knowledge are correlated with discrimination among freshmen under different peer relationships. More anti-AIDS discrimination courses should be added to AIDS education to reduce the students’ fear and stigma of HIV/AIDS patients and related risk groups.

Implementation and application of a digital cytopathological lung cancer diagnosing system / 中华外科杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy of the digital cytopathological lung cancer diagnosing system (DCLCDS) utilizing the latest computer technologies (including reinforcement learning, image segmentation and classifier) and the cytopathological knowledge on lung cancer cells.</p><p><b>METHODS</b>Separate the overlapped lung cancer cells in a slice image applying the improved deBoor-Cox B-Spline algorithm; Segment cell regions in a slice image using an image segmentation algorithm based on reinforcement learning; Ensemble different classifiers, including Decision Tree classifier, Support Vector Machine (SVM) classifier and Bayesian classifier, to achieve an accurate result of cytopathological lung cancer diagnosis.</p><p><b>RESULTS</b>The accurate diagnosis rate for lung cancer identification of 224 images of small lung lesions aspiration biopsy from 120 cases randomly selected was 92.3%. The accurate diagnosis rate for type classification of lung cancer was 82.5%. The identification rate for abnormal nuclear cells was 71.6%.</p><p><b>CONCLUSIONS</b>The DCLCDS achieves a high accuracy on cytopathological lung cancer diagnosis by solving some major problems on the cytology smears, including cell overlapping, uneven coloration and impurity. It provides a relatively objective, standard tool on cytopathological lung cancer diagnosis. It has good efficacy on early diagnosis of lung cancer.</p>
