ObjectivesTo systematically review the risk factors for intestinal injury induced by non-steroidal anti-inflammatory drugs(NSAIDs).MethodsWe comprehensively searched WanFang Data, CNKI, Web of Science, EBSCO, PubMed and The Cochrane Library databases to collect studies on risk factors of NSAIDs-induced intestinal injury. Two reviewers independently screened literature, extracted data and assessed risk of bias, and then, meta-analysis was performed by using RevMan 5.2 and STATA 12.0 software.ResultsA total of 6 case-control studies were included, in which 265 patients were in the case group and 301 patients in the control group. The results of meta-analysis showed that PPI was an independent risk factor for NSAIDs-induced intestinal injury (OR=1.59, 95%CI 1.07 to 2.35, P=0.02). In addition, patients with osteoarthritis (OR=2.44, 95% CI 1.11 to 5.36, P=0.03) or rheumatoid arthritis (OR=3.04, 95% CI 1.31 to 7.03, P=0.01) was associated with intestinal mucosal injury induced by NSAIDs. Gender, age, smoking history, drinking history, H2RA and rebamipide medication history, cardiovascular disease and cerebrovascular disease were not associated with intestinal injury.ConclusionsPPI is an independent risk factor for NSAIDs-induced intestinal injury. However, studies with high-quality, larger sample size are required to further verify that PPI increases the prevalence of intestinal injury.
目的 比较低频与高频探头超声对急性阑尾炎的诊断价值。 方法 对2010年1月－2011年6月120例急性阑尾炎的手术病理结果与超声检查结果进行回顾性分析，比较低、高频探头超声对急性阑尾炎的诊断价值。 结果 120例急性阑尾炎中，通过低频探头超声检出67例（55.8%），通过高频探头超声检出105例（87.5%）；单纯性阑尾炎以及化脓性和坏疽性阑尾炎高频探头超声检出例数明显大于低频探头超声，差异有统计学意义（P＜0.05）；阑尾周围脓肿低、高频探头超声均全部检出。 结论 高频探头超声对急性阑尾炎的检出率高于低频探头超声，但二者各有所长，在临床中联合应用能有效提高急性阑尾炎的超声诊断符合率。
