培美曲塞联合顺铂治疗肺腺癌临床疗效的Meta分析

目的评价培美曲塞联合顺铂治疗肺腺癌的临床疗效,为临床选择肺腺癌一线化疗方案提供循证证据。方法遵循Cochrane系统评价手册中随机对照试验检索策略,检索2005—2012年中国知网文献数据库中公开发表的关于培美曲塞联合顺铂治疗肺腺癌临床疗效的随机对照试验,对照组采用多西他赛联合顺铂方案,试验组采用培美曲塞联合顺铂方案。采用Jadad量表评价纳入文献的方法学质量,RevMan 5.0软件包进行数据分析。结果最终纳入8篇文献,Jadad量表评分均≥3分。Meta分析结果显示,试验组总有效率高于对照组〔OR=1.50,95%CI(1.01,2.21),P=0.04〕。结论培美曲塞联合顺铂方案治疗肺腺癌的总有效率高于多西他赛联合顺铂方案,可作为肺腺癌一线化疗方案。     

The effect of non‐surgical weight loss interventions on urinary incontinence in overweight women: a systematic review and meta‐analysis

Although the aetiology of urinary incontinence can be multifactorial, in some cases weight loss could be considered as a part of the therapeutic approach for urinary incontinence in people who are overweight. The objective of this study was to review and meta‐analyse the effect of non‐surgical weight loss interventions on urinary incontinence in overweight women. Web of Science, PubMed, Pedro, SPORTDiscus and Cochrane were systematically searched for clinical trials that met the a priori set criteria. Data of women who participated in non‐surgical weight loss interventions (diet, exercise, medication or a combination) were included in the meta‐analysis. After removing duplicates, 62 articles remained for screening on title, abstract and full text. Six articles (totalling 2,352 subjects in the intervention groups) were included for meta‐analysis. The mean change in urinary incontinence (reported as frequency or quantity, depending on the study) after a non‐surgical weight loss intervention, expressed as standardized effect size and corrected for small sample sizes (Hedges' g), was ?0.30 (95%CI = ?0.47 to ?0.12). This systematic review and meta‐analysis shows evidence that a non‐surgical weight loss intervention has the potential to improve urinary incontinence and should be considered part of standard practice in the management of urinary incontinence in overweight women.     

柴胡疏肝散加减治疗慢性萎缩性胃炎肝胃不和证的Meta分析*

目的系统评价柴胡疏肝散加减治疗慢性萎缩性胃炎(CAG)肝胃不和证的临床疗效以及安全性。方法 检索Pubmed,Web of Science,Cochrane Library,CNKI,VIP和万方数据库,纳入所有柴胡疏肝散加减治疗慢性萎缩性胃炎肝胃不和证的临床随机对照试验(RCTs),检索时间为建库至2019年10月1日,采用RevMan5.3软件进行Meta分析。结果 最终纳入11项研究,共1 068例患者。Meta分析结果显示:与常规西药治疗相比,柴胡疏肝散能有效提高肝胃不和型萎缩性胃炎患者的临床总有效率[RR=1.25,95%CI(1.19,1.33),P<0.000 01]、症状疗效总有效率[RR=1.57,95%CI(1.30,1.89）,P<0.000 01]及血清胃泌素G17水平[MD=3.61,95%CI(2.89,4.33),P<0.000 01],并能改善胃粘膜萎缩[MD=-1.53,95%CI(-1.93,-1.12),P<0.000 01]、肠上皮化生[MD=-0.79,95%CI(-0.96,-0.63),P<0.000 01]、异型增生度[MD=-0.69,95%CI(-0.84,-0.55),P<0.000 01]的病理检查积分,2组疗效差异具有统计学意义。结论 柴胡疏肝散加减治疗肝胃不和型慢性萎缩性胃炎疗效优于常规西药治疗。     

上颌快速扩弓联合前方牵引后骨性Ⅲ类伴上颌骨发育不足患者上气道变化的meta分析

目的 系统评价上颌快速扩弓联合前方牵引后骨性Ⅲ类伴上颌骨发育不足患者上气道的变化情况。方法 计算机检索 PubMed、Cochrane Library、Embase、CNKI、CBM、维普及万方数据库等中英文数据库中所有关于上颌快速扩弓联合前方牵引后骨性Ⅲ类伴上颌骨发育不足患者上气道变化方面的文献,检索时限均为建库至 2018年 3 月1日。由 2 名研究者根据纳入与排除标准筛选文献、提取资料并评价纳入研究的偏倚风险后,采用RevMan 5.3 软件进行 meta 分析。结果 最后纳入 12 篇文献,Meta 分析结果显示,上颌快速扩弓联合前方牵引后,鼻咽容积[MD=0.89 cm³,95%CI(0.36 cm³,1.42 cm³),P=0.001]显著大于治疗前,口咽容积[MD=0.44 cm³,95%CI(-0.01 cm³,0.89 cm³),P=0.05]、喉咽容积[MD=0.37 cm³,95%CI（-1.31 cm³,1.76 cm³）,P=0.61]较治疗前差异无统计学意义。上气道上部变化PNS-ad1[MD=2.11 mm,95%CI（1.87 mm,3.94 mm）,P<0.00001]、 PNS-ad2[MD=2.91mm,95%CI(1.87 mm,3.94 mm),P<0.00001]显著大于治疗前,上气道下部MPS[MD=0.47 mm,95%CI(-0.89 mm,1.87 mm),P=0.5]、IPS[MD=0.42 mm,95%CI(-0.90 mm,1.75 mm,P=0.53)]较治疗前差异无统计学意义。结论 上颌快速扩弓联合前方牵引可以增加安氏Ⅲ类伴上颌骨发育不足患者鼻咽部容积及矢状径,可通过扩大气道间隙,降低上颌骨发育不足患者发生阻塞性睡眠呼吸暂停综合征的风险。
