Objective. A meta-analysis on combined therapy of diabetic peripheral neuropathy (DPN) with breviscapine and mecobalamin was performed to evaluate the efficacy of this therapy. Methods. Six English databases (Medline, Cochrane Library, PubMed, EMBASE, Web of Science, and CINAHL) and four Chinese databases (China National Knowledge Infrastructure, VIP Journals Database, CBM, and Wanfang database) were searched for studies on the clinical trials in which DPN was treated with breviscapine and mecobalamin, and RevMan 5.1 package was employed for analyzing pooled trials and publication bias. Results. A total of 17 articles including 1398 DPN patients were identified. Homogeneity was observed among different studies (P = 0.74). The efficacy of combined therapy with breviscapine and mecobalamin was significantly better than that in control group [P < 0.0001 (OR = 5.01, 95% CI: 3.70–6.78)]. Conclusion. Available findings suggest that the therapeutic efficacy of breviscapine combining mecobalamin is superior to mecobalamin alone, and this strategy is required to be popularized in clinical practice.
Background. Our study was designed to elucidate whether there were
miRNA and mRNA aberrantly expression profiles and potential role in malignant transformation of
16HBE induced by Cd. Methods. mRNA and miRNA expression profiles were determined
in 35th Cd-induced 16HBE and untreated 16HBE by microarray. A series of bioinformatics analyses
such as predicting targets, GO, KEGG were performed to find DEGs, coexpressing networks between
miRNAs and mRNAs and its functions. Results. 498 DEGs were found. 8 Cd-responsive
novel miRNAs predicted previously were identified, and 5 of them were downregulated. 214 target
genes were predicted for the Cd-responsive miRNAs, many of which appeared to regulate gene networks.
Target gene CCM2 was showed reciprocal effect by miRNAs. According to the combination analysis,
hsa-miR-27b-3p regulated most of the mRNAs, especially upregulated expression genes. The differentially
expressed miRNAs are involved in the biological processes and channels, and these GO and KEGG
enrichment analyses result were significantly enriched in the Cd-responsive. Discussion. These
results provided a tight link for the miRNA-mRNA integrated network and implied the role of novel miRNAs
in malignant transformation of 16HBE induced by Cadmium. It is better to understand the novel
molecular mechanism of cadmium-induced tumorigenesis.
Cadmium (Cd) and its compounds are well-known human carcinogens, but the mechanisms underlying the carcinogenesis are not well understood. This study aimed to investigate whether lncRNA-MALAT1 could serve as a novel biomarker of Cd toxicity in cells, animals and Cd-exposed workers, and regulate cell proliferation, apoptosis, migration and invasion. MALAT1 expression increased gradually in CdCl transformed 16HBE cells. The cell apoptosis, migration and invasion were significantly inhibited, and the mRNA and protein expression of FOXC2, STAT, BAX, EGFR, and TGF-β1 reduced, but BCL-2 increased ( < 0.05) after silencing MALAT1 by siRNA in CdCl treated 16HBE cells of 15 and 35 passages. Cadmium increased MALAT1 expression in the lung of Cd-exposed rats in a dose-dependent manner. A significant positive correlation was observed between blood MALAT1 expression and urinary/blood Cd concentrations, and there were significant correlations of MALAT1 expression with the expressions of target genes in the lung of Cd-exposed rats and the blood of Cd exposed workers. This study suggests that the expression of MALAT1 is upregulated and regulates the cell cycle progression, proliferation, apoptosis, migration and invasion in Cd toxicity. MALAT1 may serve as a novel valuable biomarker of cadmium exposure and cadmium toxicity.
New treatments, such as sipuleucel-T and androgen receptor- (AR-) directed therapies (enzalutamide (Enz) and abiraterone acetate (AA)), have emerged and been approved for the management of castration-resistant prostate cancer (CRPC). There are still debates over their efficacy and clinical benefits. This meta-analysis aimed to investigate the efficacy and safety of sipuleucel-T and AR-directed therapies in patients with CRPC. RevMan 5.1 was used for pooled analysis and analysis of publication bias. Seven studies were included in the meta-analysis, with three studies in sipuleucel-T (totally 737 patients, 488 patients in treatment group, and 249 patients in placebo group) and four in AR-directed therapies (totally 5,199 patients, 3,015 patients in treatment group, and 2,184 patients in placebo group). Treatment with sipuleucel-T significantly improved overall survival in patients with CRPC and was not associated with increased risk of adverse event of grade ≥3 (p > 0.05). However, treatment with sipuleucel-T did not improve time-to-progression and reduction of prostate-specific antigen (PSA) level ≥50% was not significantly different from that with placebo. AR-directed therapies significantly improved overall survival in patients with CRPC and improved time-to-progression and reduction of PSA level ≥50%. AR-directed therapies did not increase risk of adverse event of grade ≥3 (p > 0.05).
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
