目的:观察整合素连接激酶(ILK)在糖尿病大鼠肾小管上皮细胞中的表达,探讨其与肾小管上皮细胞转分化(EMT)的关系.方法:雄性Wistar大鼠随机分为正常对照组(n=10)、糖尿病模型组(n=10)与糖尿病氯沙坦干预组(n=10)[氯沙坦20 mg/(kg·d)];分别于第8周、第16周每组各处死5只大鼠.留取左肾行HE和Masson染色,阅片并计算肾小管间质损伤指数、肾间质胶原面积;免疫组织化学法检测肾小管上皮细胞α-平滑肌肌动蛋白(α-SMA)、波形蛋白(Vimentin)与ILK的表达.结果:与正常对照组比较,糖尿病组大鼠肾小管间质损伤指数、肾间质胶原面积明显增加(P<0.01),肾小管上皮细胞α-SMA,Vimentin和ILK阳性表达面积明显增加(P<0.01),ILK与α-SMA呈正相关(rs=0.621,P<0.05);氯沙坦组大鼠肾小管间质损伤指数、肾间质胶原面积较糖尿病组明显减弱,其肾小管上皮细胞的ILK,α-SMA与Vimentin表达均较糖尿病组明显减弱(P<0.01).结论:糖尿病大鼠肾小管上皮细胞存在ILK高表达与EMT,二者之间可能有着重要联系;氯沙坦可下调肾小管上皮细胞ILK表达,阻抑EMT.  相似文献

目的:研究SDF1 3A基因多态性与高血压病易感性和高血压患者应用卡托普利疗效的关系.方法:运用PCR-RFLP对214名高血压患者和228名正常健康个体进行SDF1 3A基因分型. 在39名不同SDF1 3A 基因型的个体中, 13 名高血压患者同时口服卡托普利(25 mg/d) 和尼群地平 (30 mg/d), 12名高血压患者仅口服尼群地平 (30 mg/d), 所有患者连续服药8周以上,14 名正常健康个体没有服任何药物.检测所有受试者的血压变化,以此评估药物的治疗效果.结果:在卡托普利和尼群地平治疗后,SDF1 3A AA+AG基因型或GG基因型的高血压患者中血浆SDF-1水平显著高于正常健康对照组(P<0.05);AA基因型携带者与GG基因型相比较,有较低水平的血浆总蛋白和球蛋白(P<0.05);高血压患者经卡托普利治疗后,AA+AG基因型个体的收缩压降低效果明显好于GG基因型个体 (P<0.05).结论:SDF1 3A遗传多态性可以影响中国汉族高血压患者应用卡托普利的疗效.  相似文献

目的:观察清热化痰法治疗慢性阻塞性肺疾病(chronic obstructive pulmonary disease,COPD)急性加重期全身炎症反应综合征(systemic inflammatory response syndrome,SIRS)的临床疗效及其对降钙素原(procalcitonin,PCT)这一炎性指标的作用。 方法:将符合纳入标准的100例患者随机分为治疗组和对照组,每组各50例。治疗组在西医综合冶疗的基础上,加用清热化痰中药,对照组单纯用西医综合冶疗,两组疗程均为1周。在入院第1、3和第7天对患者分别进行血清PCT测定。在入院第1天和第7天分别记录患者中医证候积分,并进行疗效判定。 结果:两组治疗后中医证候积分与治疗前比较均有改善,差异均有统计学意义(P〈0.05)。治疗后,治疗组中医证候积分改善程度优于对照组,差异有统计学意义(P〈0.05)。中医证候积分减少按≥70%和〈70%进行比较,治疗组的治疗效果明显优于对照组,差异有统计学意义(P〈0.05)。PCT浓度越高,中医证候积分越高(P〈0.05)。两组入院第1、3和第7天血清PCT水平分布比较,差异均无统计学意义(P〉0.05)。 结论:清热化痰法联合西医综合治疗对患者的症状改善程度优于单纯西医综合治疗,更有利于患者症状的改善。COPD急性加重期SIRS的PCT与病情严重程度相关。  相似文献

Objective:To study the possibility of natural hydroxyapatite/chitosan composite on repairing bone defects. Methods:We developed a natural hydroxyapatite/chitosan composite that could be molded into any desired shape. The powder component consists of natural hydroxyapatite, which is epurated from bone of pigs. The liquid component consists of malic acid and chitosan. Operations were performed on the left tibias of 15 white rabbits to create two square bone defects. One of the defects was reconstructed with the composite, while the other was not repaired and used as a blank control. Three of the animals were killed at the end of 2 weeks, 4 weeks, 8 weeks, 12 weeks and 16 weeks respectively and implants were evaluated anatomically and histologically. Results:No apparent rejection reaction was found, except for a mild inflammatory infiltration observed 2 weeks after surgery. Fibrous tissue became thinner 2~8 weeks after surgery and bony connections were detected 12 weeks after surgery. The new bone was the same as the recipient bone by the 16th postoperative week. Conclusion:The hydroxyapatite/chitosan composite has good biocompatibility and osteoconduction. It is a potential repairing material for clinical application.  相似文献

Objective: The main purpose of this retrospective study is to evaluate clinical outcomes of Xive implants 3-year after insertion. Methods: 219 Xive implants were placed in 139 patients and their clinical effects were evaluated using the Albrektsson Standard. Results:The 3- year survival rate of the Xive implants is 97.26%(213/219). Eleven cases of immediate implants and 15 cases of implant insertion after maxillary sinus lifting all succeeded. The failure ratio is 6/219(2.74%) with failures resulting from excess bone loss in the implant region, peri-implant mucosal inflammation or continuous pain caused by some unknown reasons. Conclusion: Xive implants are clinically effective for the restoration of missing teeth. Immediate implant and implant following maxillary sinus lifting were also successful.  相似文献
