ABSTRACT
CNKI, PubMed and other databases were retrieved to extract eligible randomized controlled trial(RCT) about modified Xuefu Zhuyu Decoction(MXZD) combined with Western medicine(trial group) versus Western medicine alone(control group) in the treatment of leiomyoma. Therefore, a total of 25 RCTs were included, involving 2 328 patients. Bias risk evaluation tool in Cochrane Handbook 5.1.0 was used for evaluating the quality of these RCTs. Meta-analysis was performed for the reported indicators, including total efficiency, serum hormone level [progesterone(P), luteinizing hormone(LH), estradiol(E_2), follicle stimulating hormone(FSH)], uterine size, fibroids size and adverse reactions by using Stata 14.0 software. Meta-analysis showed that the total efficiency(RR=1.21,95%CI[1.17,1.25],P<0.05) of trial group was better than that of control group. Serum hormone level(WMD_P=-3.86,95%CI[-4.31,-3.41],P<0.05; WMD_(LH)=-3.64,95%CI[-4.47,-2.82],P<0.05; WMD_(E_2)=-39.99,95%CI[-53.45,-26.52],P<0.05; WMD_(FSH)=-3.79,95%CI[-4.86,-2.72],P<0.05), uterine size(WMD=-50.02,95%CI[-55.98,-44.06],P<0.05), fibroids size(WMD=-15.79,95%CI[-18.11,-13.46],P<0.05) and adverse reactions(RR=0.65,95%CI[0.48,0.88],P<0.05) of trial group were all lower than those of control group, with statistical significances. Trial sequential analysis(TSA) was performed by using TSA 0.9 software, and showed a reliable therapeutic effect of the experimental group. In short, our study indicated that modified Xuefu Zhuyu Decoction combined with Western medicine had a better therapeutic effect on leiomyoma than Western medicine alone, but more high-quality studies are needed to verify this conclusion in the future.

Objective: To establish a method of liquid chromatography-atomic fluorescence spectrometry (LC-AFS), and carry out uncertainty analysis of detecting methyl mercury in fish tissue. Methods: LC-AFS method was adopted to determine the content of methyl mercury in fish tissue. And the theory of assessment and expression about uncertainty measurement based on JJF1059.1-2012 of State Administration for Market Regulation was applied to analyze the source of factors that affect its uncertainty. Through evaluated various factors of uncertainty and calculated and combined uncertainty to obtain the extended uncertainty of measurement results. Results: The content of methyl mercury in fish tissue by using LC-AFS wasω=(817.94±105.02)μg/kg (k=2, confidence level was 95%). Conclusion: The measurement uncertainty assessment can be used in the uncertainty analysis that LC-AFS measure content of methyl mercury in fish tissue. Therefore, the results are more reliable.
