ABSTRACT
Bayesian network Meta-analysis was performed to evaluate the efficacy and safety of different Chinese patent medicines in the treatment of dilated cardiomyopathy. The PubMed, EMbase, Cochrane Library, CNKI, Wanfang, and VIP were searched for the randomized controlled trial(RCT) from the inception to May 2023. The quality of the included RCT was evaluated by the Cochrane risk of bias assessment tool, and the data were analyzed by RStudio 3.6.3 calling the "gemtc" package. A total of 96 RCTs involving 8 452 patients, 11 Chinese patent medicines, and 8 outcome indicators were included. Network Meta-analysis is described as follows.(1)In terms of improving clinical total effective rate, except Yixinshu Capsules + conventional western medicine, Shexiang Baoxin Pills + conventional western medicine, and Xinshuai Mixture + conventional western medicine, the other Chinese patent medicines combined with conventional western medicine were superior to conventional western medicine alone, and Shenqi Yiqi Dropping Pills + conventional western medicine had the best effect.(2)In terms of improving left ventricular ejection fraction(LVEF), except Yixinshu Capsules + conventional western medicine and Shensong Yangxin Capsules + conventional western medicine, other Chinese patent medicines combined with conventional western medicine outperformed conventional western medicine alone, and Shexiang Baoxin Pills + conventional western medicine had the best effect.(3)In terms of reducing left ventricular end-diastolic dimension(LVEDD), Getong Tongluo Capsules + conventional western medicine, Xinshuai Mixture + conventional western medicine, Huangqi Mixture + conventional western medicine, Tongxinluo Capsules + conventional western medicine, Wenxin Granules + conventional western medicine, and Qili Qiangxin Capsules + conventional western medicine were better than conventional western medicine alone, and Wenxin Granules + conventional western medicine had the best effect.(4)There was no significant difference in reducing left ventricular end-systolic diameter(LVESD) between Chinese patent medicines combined with conventional western medicine and conventional western medicine alone.(5)In terms of improving 6-minute walking trail(6MWT), Yangxinshi Tablets + conventional western medicine, Yixinshu Capsules + conventional western medicine, Shenqi Yiqi Dropping Pills + conventional western medicine, Wenxin Granules + conventional western medicine, and Qili Qiangxin Capsules + conventional western medicine were superior to conventional western medicine alone, and Shenqi Yiqi Dropping Pills + conventional western medicine had the best effect.(6)In reducing brain natriuretic peptide(BNP), Xinshuai Mixture + conventional western medicine ourperformed conventional western medicine alone.(7)In reducing hypersensitive C-reactive protein(hs-CRP), Shenqi Yiqi Dropping Pills + conventional western medicine, Qili Qiangxin Capsules + conventional western medicine outperformed conventional western medicine alone, and Qili Qiangxin Capsules + conventional western medicine had the best effect.(8)In terms of safety, adverse reactions were reported in both groups. In conclusion, Chinese patent medicine combined with conventional western medicine were more effective in the treatment of dilated cardiomyopathy. The combinations relieve clinical symptoms and improve cardiac function indexes, and thus can be used according to the patients' conditions in clinical practice. However, limited by the quality and sample size of the included studies, the conclusion remains to be verified by multi-center, large-sample, and high-quality RCT in the future.

Objective:To explore the relevance of the three polymorphic loci in the CUB and SUSHI multiple domains 1(CSMD1) gene with schizophrenia and its cognitive function.Methods:Polymerase chain reaction-restrictive fragment length polymorphism (PCR-RFLP) was used to detect CSMD1 gene polymorphism in 109 schizophrenia patients(case group) and 109 healthy controls(control group), and the cognitive function was evaluated by Montreal cognitive assessment (MoCA). The allele and genotype frequencies between the case group and the control group were statistically analyzed by SPSS 19.0 software.Results:(1)There were significant differences in the distribution of genotype AA, AC, CC (case group: AA, 51(46.79%), AC, 43(39.45%), CC, 15(13.76%); control group: AA, 22(20.18%), AC, 58(53.21%), CC, 29(26.61%), χ2 =18.203, P<0.001) and allele frequencies (case group: A, 145 (66.51%), C, 73 (33.49%); control group: A, 102(46.79%), C, 116(53.21%), χ2=17.269, P<0.001, OR=0.443, 95% CI: 0.301-0.652) at rs10503253 loci between the case group and the control group.(2) Differences in allele frequencies at the rs10503253 loci were associated with the visual space and executive dysfunction in the case group ( χ2=6.470, P=0.011, OR=2.089, 95% CI: 1.179-3.702). (3) Differences in allele frequencies at the rs17405197 loci were associated with language dysfunction in the case group ( χ2=9.468, P=0.002, OR=0.415, 95% CI: 0.235-0.731). (4) Differences in allele frequencies at the rs2740931 loci were associated with language dysfunction in the case group ( χ2=5.094, P=0.024, OR=2.016, 95% CI: 1.091-3.726). Conclusion:CSMD1 gene polymorphism may be a risk factor for the onset of schizophrenia, associated with symptoms of cognitive dysfunction in schizophrenia.

Result:A total of 5 071 Chinese papers and 1 136 English papers were included. The amount of domestic and foreign publications continued to rise，forming a core team represented by LI Zhao-fu，XIONG Hui，SCHLESINGER NAOMI and other authors. The research hotpots focused on the pathogenesis，diagnosis methods， Chinese and Western medicine treatment，clinical observation，risk assessment and other aspects of gouty arthritis. Both of them had their own emphases. Domestic researches tended to focus on the treatment of gouty arthritis with traditional Chinese medicine，while foreign ones focused on the pathological research and clinical investigation of gouty arthritis. Conclusion:The number of researches in the field of gouty arthritis is on the rise as a whole，and there are both consistency and differences in the research content and hot topics between domestic and foreign literature. Therefore， we should strengthen cooperation and exchange between different teams and countries，so as to promote the overall development of this field.
ABSTRACT
Objective To investigate the expression of miR-29s in the glioma stem cells,and explore how the members of miR-29s affect the bio-logical behaviors of glioma stem cells. Methods Eight patient specimens were used to culture glioma stem cells. Real-time PCR was adopted to test the expression of miR-29s. CCK-8 analysis was performed to test the proliferation ,Transwell was used to test cell migration and invasion ,and flow-cytometry analysis was carried out to test apoptosis. Results miR-29a,miR-29b and miR-29c were decreased in glioma stem cells. Over-ex-pression of miR-29s could inhibit the proliferation,cell migration and invasion,but promote apoptosis of glioma stem cells. Conclusion miR-29s acts as a cancer suppressor gene in the glioma stem cells ,and miR-29a plays the dominant functional role in the family.
