This study aimed to evaluate the cytoprotective efficiency and potential mechanisms of ATL-Ⅲ on corticosterone injured rat phaeochromocytoma(PC12) cells. Our results demonstrate that ATL-Ⅲ increases cell viability and reduces the release of lactate dehydrogenase(LDH). The results suggest that ATL-Ⅲ protects PC12 cells from corticosterone-induced injury by inhibiting the intracellular Ca^(2+) overloading, inhibiting the mitochondrial apoptotic pathway and modulating the MAPK/NF-κB inflammatory pathways. These findings provide a novel insight into the molecular mechanism by which ATL-Ⅲ protected the PC12 cells against corticosterone-induced injury for the first time. Our results provide the evidence that ATL-Ⅲ may serve as a therapeutic agent in the treatment of depression.展开更多
目的对比改良肩关节镜下双纽扣钢板动态固定与锁骨钩钢板切开复位内固定治疗RockwoodⅢ~Ⅴ型肩锁关节脱位的中期疗效。方法回顾性分析2015年1月至2019年12月华中科技大学同济医学院附属同济医院收治的51例RockwoodⅢ~Ⅴ型肩锁关节脱位...目的对比改良肩关节镜下双纽扣钢板动态固定与锁骨钩钢板切开复位内固定治疗RockwoodⅢ~Ⅴ型肩锁关节脱位的中期疗效。方法回顾性分析2015年1月至2019年12月华中科技大学同济医学院附属同济医院收治的51例RockwoodⅢ~Ⅴ型肩锁关节脱位患者资料,其中RockwoodⅢ型19例,Ⅳ型18例,Ⅴ型14例;男32例,女19例;年龄11~65岁,平均(38.6±17.2)岁。21例行改良肩关节镜下双纽扣钢板动态固定术(A组),30例行锁骨钩钢板切开复位内固定术(B组)。比较两组术中及术后住院情况,采用Constant-Murley评分、加利福尼亚大学洛杉矶分校(University of California at Los Angeles,UCLA)评分、疼痛视觉模拟评分(visual analogue scale,VAS)评估肩关节功能。结果患者术后随访24~29个月,平均(24.4±5.2)个月。相较于B组,A组术中出血量更少,住院时间更短,住院总费用更低,但手术时间更长,差异均有统计学意义(P<0.05)。术后3周、6周、12周,A组的Constant-Murley评分、UCLA评分和VAS均优于B组(P<0.05);末次随访时以上3项评价指标组间比较差异均无统计学意义(P>0.05)。两组Constant-Murley评分和UCLA评分术后生存率比较,术后早期A组明显优于B组,末次随访时两组差异无统计学意义。结论对于RockwoodⅢ~Ⅴ型肩锁关节脱位,术后早期(术后3周、6周、12周)关节镜下改良纽扣钢板动态固定更有优势,术后中期(术后24个月)两种方式的治疗效果差异无统计学意义。展开更多
