IntroductionSeveral analyses have been conducted to assess the association between leukaemia risk and XRCC3 Thr241Met polymorphism. However, their results are conflicting. Hence, this comprehensive study was carried out to obtain a more accurate assessment of the association between leukaemia risk and XRCC3 Thr241Met (rs861539) polymorphismMaterial and methodsWe searched Ovid, Chinese Biomedical Literature Database (CBM), China National Knowledge Infrastructure (CNKI), Google Scholar, PubMed database and Excerpta Medica Database (EMBASE) for potential eligible studies published as of July 2020. Pooled odds ratio (OR) and 95% confidence interval (ci) were used in evaluating the strength of the association between Thr241Met polymorphism of XRCC3 and leukaemia, and the p-value less than 0.05 (p < 0.05) was considered as the level of significance.ResultsA total of 17 studies consisting of 7241 controls and 4198 cases met our inclusion criteria. No significant association was observed between leukaemia risk and Thr241Met polymorphism of XRCC3 across the five genetic variants. In our ethnicity subgroup evaluation, we noted a significant association between leukaemia risk and Thr241Met polymorphism of XRCC3 among Caucasians under four genetic models. Furthermore, SNP (rs861539) of XRCC3 has a protective effect among Asians under four genetic models.ConclusionsThr241Met polymorphism of XRCC3 has a protective effect in the Asian population but has oncogenic potential in the Caucasian population.

AbstractDiabetic nephropathy (DN) and diabetic retinopathy (DR) are the major factors of morbidity and mortality in the patients with diabetes mellitus (DM). Growing studies have investigated the relationship between the TNF-α-308G/A polymorphism and the susceptibility to DN and DR, without achieving consensus. Thus, we conducted this meta-analysis to reach more comprehensive conclusions for these issues. Eligible studies were retrieved through electronic databases such as PubMed, Embase, Web of Science and China National Knowledge Infrastructure. Summary of odds ratios (OR) and 95% confidence intervals (CIs) were generated to evaluate the intensity of the associations. Statistical analyses were performed by STATA 11.0 and RevMan 5.2. There are fourteen eligible publications involving nineteen studies in this meta-analysis. TNF-α-308G/A polymorphism was significantly related to increasing risk of DN under recessive model (OR=1.37, 95% CI=1.03–1.83) and homozygous model (OR=1.54, 95% CI=1.15–2.06). Moreover, the similar results were also obtained in Asian groups for DN (recessive: OR=1.69, 95% CI=1.18–2.42; homozygous: OR=1.99, 95% CI=1.38–2.86; respectively), and significant association was also detected between TNF-α-308G/A and DN susceptibility in type 2 DM in recessive model (OR=1.39, 95% CI=1.02–1.89). No significant association was observed between TNF-α-308G/A and DR susceptibility in total analyses and subgroup analyses by ethnicity and type of DM. TNF-α-308G/A polymorphism may enhance the susceptibility to diabetic nephropathy, especially in Asian population and in T2DM patients, but not diabetic retinopathy.

Objective. Our aim was to assess the efficacy and safety of acupuncture for OSA patients with various severities of the disorder. Methods. Eight databases including PubMed, Cochrane Library, EMBASE, Web of Science, China National Knowledge Infrastructure (CNKI), Chongqing VIP (CQVIP), Wanfang Data, and Chinese Biomedical Literature Database (CBM) were comprehensively searched till July 2019. Randomized controlled trials (RCTs) testing acupuncture in the treatment of OSA were eligible for inclusion. Studies were selected for inclusion, and data were extracted by two authors independently. The Cochrane Collaboration’s Risk of Bias Assessment Tool and RevMan software (version 5.3) were used to evaluate the quality of studies and conduct statistical analysis. Results. Nine RCTs with 584 participants were included. The trials covered acupuncture and electropuncture. Acupuncture caused clinically significant reductions in AHI (MD: -6.18; 95% CI: -9.58 to -2.78; Z=3.56, P=0.0004) as well as in ESS (MD: -2.84; 95% CI: -4.80 to -0.16, Z=2.09, P=0.04). AHI was reduced more in the subgroup analysis of moderate OSA patients (MD: -9.44; 95% CI: -12.44 to -6.45; Z=6.18, P<0.00001) and severe OSA patients (MD: -10.09; 95% CI: -12.47 to -7.71; Z=8.31, P<0.00001). ESS was also reduced more in the subgroup analysis of moderate OSA patients (MD: -2.40; 95% CI: -3.63 to -1.17; Z=3.83, P=0.0001) and severe OSA patients (MD: -4.64; 95% CI: -5.35 to -3.92; Z=12.72, P<0.00001). Besides, acupuncture had a beneficial effect on LSaO2 (MD: 5.29; 95% CI: 2.61 to 7.97; Z=3.86, P=0.0001). The outcome of AHI and LSaO2 yielded consistent results after sensitivity analysis, but the direction of the outcome of ESS was reversed. And the quality of evidence was mainly low to very low. Conclusions. Acupuncture therapy is effective for OSA patients in reducing AHI and ESS and in improving the LSaO2 of various severities, especially in moderate and severe OSA patients. High-quality trials are urgently needed.

Abstract Purpose We aimed to conduct a meta-analysis to accurately evaluate the potential association between ADIPOQ rs2241766 gene SNP and breast cancer risk. Methods A systematic literature search on Cochrane Library, PubMed, Embase, Web of Science and China National Knowledge Infrastructure (CNKI) identified 8 articles with 1692 cases and 1890 controls. Strength of association was evaluated by pooled odds ratio (OR), 95 % confidence interval (CI) and p value. Funnel plots and Begger’s regression test were applied for testing the publication bias. Statistical analysis of all data was performed by Stata 12.0. Results The meta-analysis results indicated that the ADIPOQ rs2241766 gene polymorphism did not significantly associated with the risk of breast cancer for these genetic models (TT vs. TG + GG: OR = 1.20, 95 % CI = 0.77–1.89, p=0.417; TT + TG vs. GG: OR = 1.05, 95 % CI = 0.71–1.56, p=0.805; T vs. G: OR =1.17, 95 % CI = 0.79–1.74, p=0.437). Conclusions This study indicated that no significant relationship between the ADIPOQ rs2241766 SNP and breast cancer. Further large-scale and well-designed studies will be indispensable to confirm our result.

In Asian countries, ultrasound has been proposed as a possible alternative for mammography in breast cancer screening because of its superiority in dense breasts, accessibility and low costs. This research aimed to meta-analyze the evidence for the diagnostic performance of ultrasound compared to mammography for breast cancer screening in Asian women. PubMed, Web of Science, and China National Knowledge Infrastructure databases were searched for studies that concurrently compared mammography and ultrasound in 2000–2019. Data extraction and risk of bias were performed according to the Preferred Reporting Items for Systematic Review and Meta-Analysis Protocols (PRISMA) statement. The primary outcome was the sensitivity and specificity. Bivariate random models were used to generate pooled estimates of diagnostic parameters and 95% confidence intervals (95% CI). In total, 4424 studies were identified of which six studies met the inclusion criteria with a sample size of 124,425 women. The pooled mean prevalence of the included studies was 3.7‰ (range: 1.2–5.7‰). The pooled sensitivity of mammography was significantly higher than that of ultrasound (0.81 [95% CI 0.71–0.88] versus 0.65 [95% CI 0.58–0.72], p = 0.03), but no significant differences were found in specificity (0.98 [95% CI: 0.94–1.00] versus 0.99 [95% CI: 0.97–1.00], p = 0.65). In conclusion, based on the currently available data on sensitivity alone, there is no indication that ultrasound can replace mammography in breast cancer screening in Asian women.

Abstract Backgrounds: Numerous of case-control studies have reported the associations between Interleukin-17 (IL-17) polymorphisms and colorectal cancer, however, the results were inconsistent. The aim of this meta-analysis was to further clarify the effects of IL-17 polymorphisms on colorectal cancer susceptibility.Materials and method: Relevant Studies were extracted from electronic databases of Pubmed, Embase, Web of science, China National Knowledge Infrastructure (CNKI) and Chinese Biomedical Literature Database (CMB) up to April 2021. The Odds ratio and 95% confidence interval were conducted to estimate the strength of the associations and the Stata 13.0 software was used to perform the meta-analysis.Results: Ten articles including 2599 cases and 2845 controls were enrolled in our research after strictly literature screening. Highly significant associations between IL-17A rs2275913 polymorphism and increased colorectal cancer susceptibility were observed in all the five gene models (allelic, dominant, recessive, homozygous and heterozygous models), subgroup analysis based on ethnicity revealed that these associations existed not only in Asia population, but also in Caucasian population. However, the results showed no significantly elevated colorectal cancer risk correlated to IL-17F rs763780 polymorphism and a slightly lower colorectal cancer susceptibility for Caucasian population was discovered in the recessive and homozygous models of this mutation.Conclusion: IL-17A rs2275913 polymorphism may be an independent risk factor contributed to colorectal cancer susceptibility, while IL-17F rs763780 polymorphism displayed a possible decreased susceptibility to colorectal cancer. Future studies with large-scale samples were warranted to identify these associations.
