  • Parathyroid Hormone for the Prevention and Treatment of Postmenopausal Osteoporosis: A Systematic Review

    Objective To assess the efficacy and safety of parathyroid hormone (PTH) on bone mineral density (BMD) and fractures in postmenopausal women with osteoporosis. Methods We searched MEDLINE (1966 to March 2008), EMBASE (1974 to March 2008), The Cochrane Library (Issue 1, 2008), Current Controlled Trials, The National Research Register, CBM (1983 to March 2008) and CNKI (1994 to March 2008). Some related journals were hand searched as well. The quality of included randomized controlled trials (RCTs) was evaluated and meta-analysis was conducted by The Cochrane Collaboration’s software RevMan 4.2.10. Results Twelve studies involving 5550 patients were included. PTH alone or in combination with antiresorptive drugs reduced the risk of vertebral fracture (RR=0.34, 95%CI 0.26 to 0.45, Plt;0.000 01), and increased spine BMD (SMD 0.41, 95%CI 0.17 to 0.65, P=0.0009) and femoral neck BMD (SMD 0.13, 95%CI 0.03 to 0.22, P=0.008). The rate of drop out and loss to follow-up because of adverse events was significantly higher in the PTH group (Peto-OR=1.69, 95%CI 1.39 to 2.05, Plt;0.000 01). Conclusion  PTH is effective in the prevention and treatment of postmenopausal osteoporosis, especially in patients with preexisting osteoporotic fractures or with very low bone density. PTH alone or in combination with antiresorptive drugs can reduce the risk of vertebral fractures and increase spine and femoral neck BMD. PTH is more effective than alendronate, but these two should not be used as a combined treatment.

  • 纳米碳混悬液在食管癌根治术中的应用

    目的探讨钠米碳混悬液在食管癌根治术中淋巴示踪的应用效果。 方法2012年7月-2013年5月诊治的80例食管癌患者随机分为纳米碳组和对照组各40例,前者于术中先向癌灶周围注入钠米碳后再行根治术,后者则不应用纳米碳直接行食管癌根治术。记录黑染淋巴结与未黑染淋巴结数量以及淋巴结转移情况。 结果钠米碳组平均每例清除(17.9±5.8)枚淋巴结,淋巴结黑染率为51.7%;对照组平均每例清除(14.1±5.3)枚淋巴结,纳米碳组淋巴结清除数明显高于对照组(t=3.041,P=0.003)。纳米碳组黑染淋巴结转移率13.0%,对照组淋巴结转移率7.3%,纳米碳组黑染淋巴结转移率明显高于对照组(χ2=8.379,P=0.004),同时纳米碳组微小转移淋巴结清除率高于对照组(χ2=4.047,P=0.044)。两组术后并发症发生率差异无统计学意义(P>0.05)。 结论钠米碳混悬液淋巴结示踪效果良好,操作简便,能指导医师制定淋巴结清扫方案,为术后提供更加准确的病理分期。
