  • Bladder Cancer Antigen BTA stat and Urine Cytology in Bladder Cancer Diagnosis: A Meta-analysis

    Objective To systematic review of bladder cancer antigen (BTA) stat and urine cytology (UC) in the diagnosis of bladder cancer. Methods MEDLINE (Jan.1966 to June 2008), EMbase (Jan.1988 to June,2008), Cochrane Library (Issue 1,2008), CMCC (1979 to June, 2008) and CNKI (Jan.1979 to June, 2008) were searched for studies about BTA stat and cytology in the diagnosis of bladder cancer. The search strategy was made according to the Collaborative Review Group search strategy. Quality of included trials wa assessed by quality assessment of diagnostic accuracy studies.Data were extracted by two reviewers using the designed extraction form. The software MetaDiSc1.4 was used to review management and data analysis. Results In total, 71 relevant studies were searched, of which 13 were included and 58 were excluded, with 3 733 patients involved. Heterogeneity (except for threshold effect) was found within these studies. A meta-analysis was performed using random effect model. Pooled accuracy indicators of sensitivity, specificity, positive likelihood ratio (LR) , negative LR and diagnostic odds ratio (dOR) and 95%CI of BTA stat and UC were 0.68 (0.65,0.70), 0.74 (0.72, 0.76), 2.51 (2.04, 3.09), 0.46 (0.38, 0.55), 5.66 (3.87, 8.29) and 0.41 (0.39, 0.44), 0.97 (0.97, 0.98), 12.64 (7.58, 21.08), 0.62 (0.55, 0.71), 22.16 (12.38, 39.66), respectively. The sensitivity of both methods increased as the higher of tumor grade and stage, and the incipient tumor was higher than the recurrence. Area under curve (AUC) of SROC curve of BTA stat and UC were 0.753 5 and 0.711 9, and Q index were 0.696 3 and 0.662 4, respectively. Conclusions The performance of urine BTA stat is moderate in the diagnosis of bladder tumor. It can not replace the traditional urine cytology and diagnose the bladder cancer alone, but which can be an available noninvasive examination and an important adjunct of preoperative detecting and postoperative monitoring of bladder tumor.

  • Effectiveness and Safety of Tension-free Vaginal Tapes versus Burch Colposuspension for Female Stress Urinary Incontinence: A Systematic Review and Meta-analyses of Randomized Controlled Trials

    Objective To evaluate the effectiveness and safety of tension-free vaginal tapes (TVT) compared with Burch colposuspension for female stress urinary incontinence (SUI). Methods We searched MEDLINE (1966 to October 2007), EMBASE (1988 to October 2007), Cochrane Central Register of Controlled Trials (1993 to October 2007), CMCC (1979 to October 2007) and CNKI (January 1979 to October 2007). We collected randomized controlled trials (RCTs) comparing TVT with Burch colposuspension in the treatment of SUI. Data were extracted and evaluated by two reviewers independently. The Cochrane Collaboration’s RevMan 4.2 was used for data analyses. Results Ten RCTs reporting data on effectiveness and safety of TVE versus Burch colposuspension were included. Meta-analyses showed that TVT was superior to Burch colposuspension as measured by the overall cure rate (OR 1.73; 95%CI 1.26 to 2.38; P=0.0007), negative stress test (OR 2.54; 95%CI 1.71 to 3.78; Plt;0.00001) and negative pad test (OR 1.67; 95%CI 1.16 to 2.41; P=0.006). The total complication rate was higher after TVT (OR 1.39; 95% CI 1.08 to 1.80; P=0.01), while the re-operation rate was significantly higher after Burch colposuspension (OR 0.29; 95%CI 0.10 to 0.80; P=0.02). The incidences of haematoma (OR 1.06; 95% CI 0.39 to 2.84; P=0.91), urinary tract infection (OR 1.27; 95% CI 0.64 to 2.52; P=0.50) and lower urinary tract symptoms (OR 1.20; 95% CI 0.89 to 1.62; P=0.23) were similar after TVT and Burch colposuspension. Conclusion The evidence for short-term superiority of TVT is currently limited. Although the re-operation rate is lower, the risk of bladder or vaginal injury is higher with TVT. Methodologically sound and adequately powered RCTs with long-term follow-up are needed.

  • Investigation on Different Milk Fed to Low-birth-weight Neonatal

    目的 探讨早产儿配方奶及水解蛋白奶在住院早产低出生体重儿喂养过程中,在胃肠保护作用方面有无差异,以期进一步有效指导入院低体重儿乳制品的合理选择。 方法 收集新生儿科NICU 2008年2月-2010年8月收治的早产低出生体重儿156例,采用回顾性调查分析方法,通过翻阅病历收集新生儿的性别、孕周、出生体重、开奶日龄、持续喂养天数以及所患疾病。按照喂养开奶类型不同分为水解蛋白奶喂养组(A组,111例)和早产儿配方奶喂养组(B组,45例)。 结果 两组患儿性别、开奶日龄、持续喂养天数、胎龄、疾病分布上均无统计学差异(P>0.05),A组和B组的胃肠功能障碍各临床特点发生概率无统计学差异。 结论 在住院生命体征相对稳定的早产低出生体重儿,无论是早产儿配方奶喂养还是水解蛋白奶喂养,其患儿的喂养不耐受发生情况无统计学差异。
