目的 探讨肝脏脂肪变性对肝脏切除手术安全性及预后的影响。方法 选取2012年1月—2014年12月在我院接受肝切除术治疗的肝癌患者172例,根据HE染色结果,172例患者中无脂肪变性106例(对照组),轻度脂肪变性42例(轻度组),中重度脂肪 24例(中重度组),比较各组患者基本资料(性别、年龄等)、手术情况、生化指标、术后并发症、住院时间等。结果 三组患者体重指数(BMI)差异有统计学意义(P＜0.05),中重度组BMI最高,为(26.94±3.14)kg/m²;中重度组患者手术时间、术中出血量、输注红细胞和肝门阻断时间分别为(182.39±42.17)min、(553.07±50.22)mL、(1.18±0.34)U和(20.15±6.07)min,均高于其他两组(P＜0.05);中重度组患者重度并发症发生率为45.83%,高于对照组和轻度组的9.43%和9.52%(P＜0.05);中重度组住院时间和ICU时间分别为(23.06±7.30)d和(3.71±1.03)d,高于其他两组(P＜0.05)。结论 轻度肝脏脂肪变性对手术基本无影响,而中重度脂肪变性会增加手术时间和出血、重度并发症发生较多,不利于手术的安全性以及预后。

Objective To explore the effect of liver steatosis on liver resection safety and the prognosis. Methods Selected from January 2012 to December 2014 in our hospital liver resection of 172 cases of liver cancer patients, according to the results of HE staining, 172 patients without fatty degeneration in 106 cases (control group), 42 cases of mild steatosis (mild steatosis group), 24 cases of severe fatty (moderate and severe steatosis group),observed each group patients the clinical characteristics, surgery situation, biochemical index, postoperative complications, hospitalization time, etc. Results Body mass index(BMI)of patients in the three groups difference was statistically significant (P<0.05), moderate and severe steatosis group had the highest BMI (26.94±3.14)kg/m²; in moderate and severe steatosis group, surgery time, intraoperative bleeding volume, infusion of red blood cells and hepatic portal occlusion time were (182.39±42.17) min, (553.07±50.22) ml, (1.18±0.34) U and (20.15±6.07) min. They were significantly higher than that of the control group and mild steatosis group (P<0.05); moderate and severe steatosis patients with severe complication rate was 45.83%,significantly higher than that in the control group and the mild steatosis 9.43% and 9.52%. The difference was statistically significant (P<0.05); In moderate and severe steatosis group, hospitalization time and ICU were (23.06±7.30) d and(3.71±1.03) d, significantly higher than that in the control group and the mild steatosis group(P<0.05). Conclusion Mild liver steatosis have no effect on the surgery, severe liver steatosis may increase the surgery time and bleeding, severe complications occurred more, is not conducive to the safety of the surgery and prognosis.

       目的   评价现有关于干预组仅涉及不同针具针刺或联合常规针刺治疗腰椎间盘突出症系统评价的方法学质量，以比较不同针具针刺治疗腰椎间盘突出症的治疗效果。方法   通过CNKI（中国知网）、万方数据库、VIP（维普）、PubMed、Web of Science等数据库以及其他相关电子资源，对诊断、治疗腰椎间盘突出症的多种针灸技术进行全面的研究。使用AMSTAR2软件，对所有参与的系统性评估结果进行地分析，并根据不同的检测结果，确定文献筛选标准。通过Revman5.4和Cochrance风险偏倚工具，以及Stata16.0的网格Meta分析，挑选了3 381个满足纳入排除要求的随机对照试验。结果   以Stata 16.0统计软件制作排序图可知，杵针+电针的临床有效率SUCRA=81.6%排名第一；目测类比评分显示，银质针SUCRA（用于评估疗效的指标）=95%，排名第一。结论   根据现有的研究证据，杵针+电针以及银质针优于其他9种干预措施，但确切的结果仍需要大量的随机对照试验来证明。

       Objective  To evaluate the methodological quality of the existing  systematic evaluation of the intervention group involving only different needle sets of acupuncture or combined with conventional acupuncture in the treatment of lumbar disc herniation，in order to compare the therapeutic effect of different needle sets of acupuncture in the treatment of lumbar disc herniation．Methods  Through CNKI，Wanfang database，VIP，PubMed，web of  science and other  databases as well as other  relevant resources，a variety of acupuncture techniques for the diagnosis and treatment of lumbar disc herniation were comprehensively studied．Through the use of AMSTAR2 software，all participating systematic evaluation results were effectively analyzed，and according to different test results，which literature meets the requirements were determined．Through revman5.4，Cochrane risk bias tool，and grid meta-analysis of stata16.0，3 381 RCTs meeting the inclusion and exclusion requirements were selected．Results  According to the ranking chart made by stata16.0 statistical software，the clinical effective rate of pestle needle + electroacupuncture ranked first with sucra=81.6%．According to the visual analogy score，the silver needle sucra=95%，ranking first．Conclusions  According to the existing research evidence，pestle needle + electroacupuncture and silver needle are better than the other nine interventions，but the exact results still need a large number of randomized controlled trials to prove．
