目的 探讨含左氧氟沙星的三联疗法作为一线方案对幽门螺杆菌感染治疗的有效性和安全性。 方法 选择2008年9月－2011年3月125例确诊为幽门螺杆菌感染的初治患者，随机分为雷贝拉唑、阿莫西林联合左氧氟沙星组（A组）和雷贝拉唑、阿莫西林联合克拉霉素组（B组），经治疗7 d后比较两组根除率和不良反应发生率。 结果 A、B组幽门螺杆菌符合方案分析根除率分别为91.8%、77.6%，意向性治疗根除率分别为88.9%、72.6%，A组根除率高于B组，差异有统计学意义（P＜0.05）。A、B组不良反应发生率分别为4.8%、3.2%（P＞0.05）。 结论 以左氧氟沙星、阿莫西林、雷贝拉唑为组合的三联疗法能显著提高幽门螺杆菌感染的初治成功率，不良反应少，安全有效。
Bladder cancer is the most common malignant tumor in the urinary system. The standard treatment of muscle-invasive bladder cancer (MIBC) is the radical cystectomy combined with pelvic lymphadenectomy. In recent years, radiotherapy has played an important role in the MIBC bladder-preserving treatment model. This article will review the advances in the application of radiotherapy for bladder preservation in MIBC, and introduce the application progress of radiotherapy in trimodality therapy of adjuvant radiotherapy and chemotherapy after transurethral resection of bladder tumors, radical radiotherapy, preoperative radiotherapy, radiotherapy combined with immunotherapy, the development and challenges of radiotherapy technology, and radiotherapy-related adverse reactions. The aim of this article is to provide a reference for further exploration of a more scientific and effective comprehensive treatment mode for bladder preservation.
