Objective To assess the effectiveness of exemestane in the treatment of postmenopausal women with breast cancer. Methods We searched The Cochrane Library, PubMed, CBMdisc, and CNKI to identify randomized controlled trials (RCTs) that met the inclusion and exclusion criteria. Two reviewers extracted the data and evaluated the quality of included trials, respectively. Meta-analysis was performed using RevMan 5.0 software. Results A total of 12 RCTs involving 6 166 participants were included, and the results of meta-analyses showed that: (1) When used in neoadjuvant endocrine therapy after operation, exemestane was more effective in progression-free survival than tamoxifen; (2) When used in rescue therapy, exemestane was more effective in objective response than tamoxifen, but not more effective than letrozole or anastrozole; (3) When used in new neoadjuvant endocrine therapy before operation, exemestane was not more effective than letrozole, and there was too little research about it. Conclusions The current evidence shows that exemestane has certain short-term therapeutic effect, but its long-term therapeutic effect is unknown. More high-quality clinical trials are expected for further study.

Methods A patient with dilated cardiomyopathy was admitted in October, 2010. During the procedure, the use of amiodarone hydrochloride injection made the patient suffer from liver and kidney dysfunction. We retrieved the literatures about liver and kidney toxicity of amiodarone from CNKI, Pubmed, and Embase (from the establishment of the databases to November 2011). We also ssessed the possibility of the adverse drug reaction, discussed the mechanism of amiodarone-induced hepatic insufficiency. Results According to the literature, There was a great possibility of hepatic insufficiency induced by amiodarone, and the total score of the Naranjo probability score was 7. Conclusion It is important to pay more attention to the pharmaceutical care of amidarone to timely recognize and effectively prevent or treat hepatic and renal insufficiency induced by intravenous injection with amiodarone.
Objective To identify the N6-methyladenosine (m6A)-related characteristic genes analyzed by gene clustering and immune cell infiltration in myocardial ischemia-reperfusion injury (MI/RI) after cardiopulmonary bypass through machine learning. Methods The differential genes associated with m6A methylation were screened by the dataset GSE132176 in GEO, the samples of the dataset were clustered based on the differential gene expression profile, and the Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis of the differential genes of the m6A cluster after clustering were performed to determine the gene function of the m6A cluster. R software was used to determine the better models in machine learning of support vector machine (SVM) model and random forest (RF) model, which were used to screen m6A-related characteristic genes in MI/RI, and construct characteristic gene nomogram to predict the incidence of disease. R software was used to analyze the correlation between characteristic genes and immune cells, and the online website was used to build a characteristic gene regulatory network. Results In this dataset, a total of 5 m6A-related differential genes were screened, and the gene expression profiles were divided into two clusters for cluster analysis. The enrichment analysis of m6A clusters showed that these genes were mainly involved in regulating monocytes differentiation, response to lipopolysaccharides, response to bacteria-derived molecules, cellular response to decreased oxygen levels, DNA transcription factor binding, DNA-binding transcription activator activity, RNA polymerase Ⅱ specificity, NOD-like receptor signaling pathway, fluid shear stress and atherosclerosis, tumor necrosis factor signaling pathway, interleukin-17 signaling pathway. The RF model was determined by R software as the better model, which determined that METTL3, YTHDF1, RBM15B and METTL14 were characteristic genes of MI/RI, and mast cells, type 1 helper lymphocytes (Th1), type 17 helper lymphocytes (Th17), and macrophages were found to be associated with MI/RI after cardiopulmonary bypass in immune cell infiltration. Conclusion The four characteristic genes METTL3, YTHDF1, RBM15B and METTL14 are obtained by machine learning, while cluster analysis and immune cell infiltration analysis can better reveal the pathophysiological process of MI/RI.
Objective To assess the effectiveness and safety of Tongxinluo Capsule in the treatment of vertebrobasilar artery insufficiency. Methods The Cochrane Library, MEDLINE, VIP and CNKI were searched. Two authors independently collected data, including randomized controlled trials that met the inclusion criteria. They evaluated the quality of these trials and performed meta-analysis using The Cochrane Collaboration’s RevMan 5.0. Results Eleven studies involving 1157 participants were included. All the included studies were inadequate at reporting randomization, concealment of allocation and blinding. Meta-analysis based on the included studies showed that Tongxinluo Capsule with Danshen was better than Danshen alone in vertebrobasilar artery insufficiency (RR= 1.35, 95%CI 1.24 to 1.48) and blood flow velocity of vertebrobasilar artery (WMD=3.60, 95%CI 2.44 to 4.77 and WMD=3.46, 95%CI 1.89 to 5.04). Tongxinluo Capsule with simple basic therapy was better than simple basic therapy alone in vertebrobasilar artery insufficiency (RR=1.21, 95%CI 1.11 to 1.31) and blood flow velocity of vertebrobasilar artery (WMD=3.85, 95%CI 2.19 to 5.51). Conclusion Tongxinluo Capsule is an effective and safe drug for vertebrobasilar artery insufficiency. However, due to the limited quantity and quality of the included studies, we can not draw a firm conclusion about the effectiveness of Tongxinluo Capsule compared to the simple basic therapy or Danshen. The results suggest that further and larger-scale trials using Tongxinluo Capsule for vertebrobasilar artery insufficiency are needed.
