To systematically review the efficacy and safety of Danhong injection for patients with idiopathic pulmonary fibrosis(IPF), two researchers electronically searched PubMed, EMbase, Web of Science, Cochrane Library, CNKI, CBM, WanFang Data and VIP databases from the date of establishment to May 2016 for all randomized controlled trials(RCTs) and quasi-RCTs on the use of Danhong injection in patients with IPF. Manual search in relevant journals and search of relevant literature on other websites were also performed. The data extraction and quality assessment of included RCTs and quasi-RCT were conducted by two reviewers independently. Then, Meta-analysis was conducted by using RevMan 5.3 software. A total of 12 RCTs involving 844 patients were included, 423 cases in experiment group and 421 cases in control group. The results of meta-analysis indicated that the Danhong injection group was superior than the control group in clinical effectiveness(RR=1.36, 95%CI 1.25 to 1.49, P<0.000 01), increased DLCO value(MD=4.25, 95%CI 3.32 to 5.18, P<0.000 01), and increased PaO2 value(MD=14.51, 95%CI 12.35 to 16.68, P<0.000 01). The analysis results showed that Danhong injection could significantly reduce the level of TGF-β1 in serum. There were no serious or frequently happened adverse effects in the Danhong injection group, indicating high safety and good tolerance of Danhong injection in treatment of IPF. The current evidences suggested that Danhong injection in short term use(<12 weeks) could increase clinical effectiveness, improve DLCO and PaO2, and decrease the level of TGF-β1 in serum of IPF patients, with less adverse effects. However, these results should be carefully interpreted due to the low methodology quality and small sample size of trials, and this conclusion had to be further verified by high quality, large scale and double blinded RCTs.
Although many studies have investigated the association of single nucleotide polymorphisms (SNPs) in transforming growth factor beta1 (TGF-β1) gene with pulmonary fibrosis (PF), but their association is still controversial. To clarify this, we performed a meta-analysis.Studies related to TGF-β1 and PF were retrieved from PubMed, Medline, Embase, Scopus, and Wanfang (up to November 30, 2017). We targeted TGF-β1 SNPs that have been reported by ≥3 studies to be included in the current meta-analysis, resulting in only 1 final SNP (rs1800470). The odds ratios (ORs) and 95% confidence intervals (CIs) were estimated in the models of allele comparison (T vs C), homozygote comparison (TT vs CC), dominant (TT vs TC + CC), recessive (TT + TC vs CC) to evaluate the strength of the associations.A total of 7 case-control studies were included in this meta-analysis. Overall, no significant association between TGF-β1 rs1800470 and PF was found (T vs C: OR [95% CI] = 0.96 [0.80, 1.15]; TT vs CC: 0.87 [0.61, 1.22]; TT vs TC + CC: 0.80 [0.62, 1.04]; TT + TC vs CC: 1.13 [0.83, 1.54]). In subgroup analyses by ethnicity or original disease, no statistically significant association between TGF-β1 rs1800470 polymorphisms and PF was demonstrated.This meta-analysis revealed that TGF-β1 rs1800470 polymorphism was not associated with susceptibility to PF development.
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.
