目的 评价盐酸氨基葡萄糖治疗膝骨关节炎的疗效。 方法 将2012年1月－5月收治的150例膝骨关节炎患者随机分为A、B、C组。A组给予盐酸氨基葡萄糖治疗，B组给予碳酸钙D3片治疗，C组给予盐酸氨基葡萄糖联合碳酸钙D3片治疗，疗程8周。3组患者膝关节疼痛发作时服用塞来昔布并记录用量。比较试验前后3组患者骨关节炎指数评分（WOMAC）以及第1、8周塞来昔布用量变化情况。 结果 3组患者WOMAC总分、疼痛程度评分、关节僵硬程度评分、日常活动困难程度评分改善值比较，差异均无统计学意义。经过8周治疗，塞来昔布每周用量减少值A、B、C组分别为（0.41 ± 0.17）、（0.16 ± 0.22）、（0.46 ± 0.19）g，A、C组高于B组（P＜0.01），A、C组每周用量减少值差异无统计学意义（P＞0.05）。 结论 短期使用盐酸氨基葡萄糖治疗膝骨关节炎，在关节疼痛、僵硬及功能改善方面并不优于碳酸钙D3片，但可通过减少非甾体抗炎药物用量，使患者获益。
Objective To evaluate the efficacy and safety of the silicone stent for treatment of three common benign central airway stenosis. Methods We retrospectively reviewed 40 patients with benign airway stenosis who were treated with a Dumon silicone stent at Affiliated Hospital of Guizhou Medical University between November 2019 to October 2023, including 14 cases of tracheobronchial tuberculosis (TBTB) stenosis, 14 cases of stenosis after tracheal intubation,and 12 cases of stenosis after tracheotomy. The clinical data and information on bronchoscopic interventional procedures and related complications were collected and analyzed, for evaluating the short-term efficacy, long-term efficacy and stent-related complications. Results The 40 patients were successfully implanted of silicone stents for 48 times totally. The mMRC score, KPS score, blood oxygen saturation and the diameter of the narrowest airway were significantly improved (P<0.05) after the implantation of silicone stents in all patients. Patients in TBTB group achieved inferior efficacy than those in the other two groups (P<0.05), while there was no significant therapeutic effect between tracheal intubation and tracheotomy groups (P>0.05). The main complications after the implantation of silicone stents were granulation hyperplasia, sputum retention and stent displacement. There were higher incidence rates of granulation hyperplasia and sputum retention in the TBTB group compared with the tracheal intubation and tracheotomy groups (P<0.05 ), while there was no statistically significant difference in incidence rates of granulation hyperplasia and sputum retention between the last two groups. Meanwhile, there was no significant difference in the proportion of stent displacement among the three groups.Conclusions The efficacy and safety were satisfied in the treatment of the three common benign central airway stenosis,with a recommendation for the treatment of refractory benign airway stenosis. However, the treatment effect of the TBTB group is inferior to that of the tracheal intubation and tracheotomy groups, with higher rates of obvious granulation hyperplasia and sputum retention simultaneously. More detailed follow-up management was recommended for TBTB patients implanted with silicone stents to avoid the development of stent-related minor complications into serious complications with a worse prognosis.
