Sixty patients were assigned to two groups of thirty patients for each: one group received treatment with self-ligating brackets and the other with conventional ligated edgewise brackets. All patients were treated with extraction of the maxillary first premolars. The EARR of the maxillary central incisors was evaluated on the periapical radiographs and cephalograms, taken before and after orthodontic treatment. The GCF was also collected non-invasively from the mesial and distal sides of central incisors by using filter paper strips before and after orthodontic treatment. Enzyme-linked immunosorbent assay (ELISA) kits were used to determine the IL-6 levels in the GCF samples. A significant difference was found in the amount of EARR between the patients with self-ligating brackets and conventional brackets. The mean amount of EARR was significantly lower for self-ligating brackets than conventional brackets (p < 0.05). The GCF levels of IL-6 for the patients with self-ligating brackets appliance were significantly lower than for those with the conventional brackets (p < 0.05). These results show that the mean amount of EARR and the GCF levels of IL-6 were significantly lower in the patients treated using low-force low-friction appliances than conventional brackets. Therefore, self-ligating brackets may be a useful system for reducing inflammation and EARR.展开更多
目的探讨瓣膜性房颤患者术中同期左心耳外结扎治疗方式对术后血栓形成的影响。方法采用回顾性分析选取2015年1月—2018年10月在贵州省人民医院因风湿性心脏瓣膜病合并房颤入院的320例患者的临床资料,随机分为两组(治疗组160例与对照组16...目的探讨瓣膜性房颤患者术中同期左心耳外结扎治疗方式对术后血栓形成的影响。方法采用回顾性分析选取2015年1月—2018年10月在贵州省人民医院因风湿性心脏瓣膜病合并房颤入院的320例患者的临床资料,随机分为两组(治疗组160例与对照组160例),治疗组术中同期行左心耳外结扎,对照组左心耳未予结扎,分别于术后采用门诊+电话随访1年,对两组术后脑卒中发生情况进行比较分析。结果治疗组术后1月、3个月、6个月及1年脑卒中病例数(3 vs 12、5 vs 20、10 vs 28、17 vs 34)均低于对照组,差异有统计学意义(χ^(2)=5.666、9.763、9.675、6.741,P<0.05)。结论瓣膜性房颤患者术中同期行左心耳外结扎对预防脑卒中有效。展开更多
