ObjectiveTo evaluate the effects and safety of edaravone combined with shuxuening for cerebral infarction. MethodsThe Cochrane Library, PubMed, EMbase, CBM, CNKI and VIP databases were searched from their establishments up to March 31, 2013. We used the method recommended by the Cochrane collaboration to perform a meta-analysis of randomized controlled trails (RCTs) with RevMan 5.0 software. ResultsSeventeen studies were included. The results of Meta-analysis demonstrated that edaravone combined with shuxuening were more efficient in reducing the score of neural function deficient scale and higher in the total effective rate (P<0.05), while there was no difference in the incidence of adverse reactions (P>0.05). ConclusionThe study suggests that edaravone combined with shuxuening is effective for cerebral infarction, but it also needs further studies to provide more sufficient evidence.
目的 比较腹腔镜胆囊切除术（LC）与小切口胆囊切除术（MC）在老年患者中的临床效果，以指导临床选择应用。 方法 回顾性分析笔者所在医院2010年7月至2013年7月期间行LC（LC组，n=109）及MC（MC组，n=111）的老年患者的临床资料，比较2组术中和术后相关指标的差异。 结果 LC组和MC组患者的手术时间〔（45.72±6.14）min比（40.67±6.02）min〕、术中出血量〔（10.18±3.31）mL比（11.13±2.93）mL〕、住院时间〔（9±5）d比（10±5）d〕及总并发症发生率〔28.4%（31/109）比31.5%（35/111）〕比较差异均无统计学意义（P＞0.05）；但LC组患者的术后疼痛程度轻、胃肠道功能恢复时间短〔（46.3±10.5）h比（71.4±9.8）h〕、住院费用较高〔（8 010±450）元比（4 800±680）元〕、切口感染发生率较低〔0（0）比15.3%（17/111）〕、肺部感染发生率较高〔17.4%（19/109）比9.9%（11/111）〕，P＜0.05。 结论 LC对老年胆囊结石或胆囊炎患者具有更好的临床效果；但对心肺功能异常者，尤其是不能耐受全麻和气腹的患者选择MC更为合适，所以临床上应视患者具体情况加以选择。
Tuberculosis remains a major public health problem. Genetic epidemiological studies have shown that the differences in host genes partly determine the susceptibility to tuberculosis. The occurrence of tuberculosis is the result of the joint action of Mycobacterium tuberculosis and host gene regulation immune response. The study of susceptibility candidate genes has differences in race, population and region, and the study of susceptibility gene polymorphism still has a long way to go in clinical precision diagnosis and treatment. The study and clinical application of mendelian susceptibility to mycobacterial disease can be used as a classic application of precision medical treatment in tuberculosis; although it is a rare case, this model is worthy of reference.
Silicone oil is widely used in intraocular filling of fundus disease after vitrectomy, which improves retinal reattachment rate andpostoperative visual function of patients. With the era of minimally invasive vitreous surgery coming, the utilization rate of silicone oil filling is decreasing, however, it still plays an indispensable role in the surgical treatment of complex fundus diseases. In the process of using silicone oil, the indications should be strictly selected, and the potential risks should be fully considered and possibly avoided. The study of vitreous substitutes with certain physiological functions is currently a research hotspot in the field of fundus diseases.
Objective To assess different anticoagulant regimens in pregnant women with mechanical heart valves: taking oral warfarin throughout the pregnancy, or heparin in the 1st trimester and oral warfarin for the other trimesters. The main outcome measures were major maternal complications and perinatal outcomes. Methods The MEDLINE, EMbase, CBM and CNKI were searched. The quality of the included studies was evaluated and data were extracted by two reviewers independently. Meta-analyses were performed on the results of homogeneous studies. Result Seven studies involving 629 pregnancies in 469 patients met the inclusion criteria for this review, all of which were retrospective surveys. The comparison between the administration of heparin in the 1st trimester plus oral warfarin for the other trimesters and warfarin throughout the pregnancy showed that, there are not significant different in the incidence of major maternal complications and the incidence of adverse perinatal outcomes. Conclusion Compared with the administration of warfarin throughout the pregnancy, the administration of heparin in the 1st trimester and oral warfarin for the other trimesters might increase the incidence of major maternal complications, but with a similar incidence of adverse perinatal outcomes.
目的:探讨使用Moss Miami系统经骶棘肌肌间隙入路在APERTURE工具的引导下微创治疗腰椎滑脱症的疗效。方法:20例腰椎滑脱症患者(男11例,女9例),年龄30～65岁(平均40岁)。其中退变性14例、峡部裂5例、腰椎间盘突出合并钙化1例;Ⅰ度滑脱15例,Ⅱ度滑脱5例。滑脱部位:L4滑脱14例,L5滑脱6例,采用全麻俯卧位下经下腰部正中小切口(5cm),经双侧骶棘肌肌间隙入路在APERTURE工具的引导下放置Moss Miami系统进行复位固定和椎体间及后外侧植骨融合。结果:本组患者术中在C臂X光机监视,经骶棘间隙放置Moss Miami固定系统简单易行,切口较小、显露好、出血少,对骶棘肌等软组织造成的损伤轻,复位固定效果满意。术后经6月随访表明:本组患者腰腿痛等临床症状缓解,X线片显示滑脱复位无丢失、植骨融合良好、内固定器械无松动及断裂。结论:在C臂X光机监视下,采用Moss Miami经骶棘肌肌间隙入路在APERTURE工具的引导下治疗腰椎滑脱症具有切口小、肌肉软组织损伤轻、出血少、固定器械放置简单易行等优点,有利于患者术后康复。
Objective To investigate the roles of cell apoptosis and the gene expressions of Fas, FasL, bcl-2 and bax in acute rejection of pancreaticoduodenal transplantation and to evaluate the function of duodenum biopsy for early detection of rejection in rats. Methods Wistar and SD rats were divided into two groups: ①Wistar rats that underwent allogenic pancreaticoduodenal transplantation from the organs of SD rats; ②Wistar rats that received homogenic transplantation. The grafts were then harvested on day 3, 5 and 7 after the transplantation, and all graft samples were observed with HE staining and TUNEL was also used to detect apoptotic cells. The expressions of Fas, FasL, bcl-2 and bax were measured by immunochemical method. According to Nakhleh’s score, pathologic features of transplanted pancreas and duodenum were ranged from one to three scores in order. Results The percentage of same or different scores between the pathological scores of pancreas and duodenum in allogenic pancreaticoduodenal transplantation group were 61.1% (11/18) and 38.9% (7/18) respectively, and there were 6 specimens of pancreatic tissue got higher scores with only one higher score for duodenum. There were significant differences of histopathologic rejection scores and apoptotic indices between the two groups, respectively (P＜0.05， P＜0.01). Apoptotic indices of pancreas and duodenum both showed positive correlations with histopathologic rejection scores (r=0.965， P＜0.01; r=0.942, P＜0.01). The rejection score and apoptotic index elevated, the expression of FasL increased, bcl-2 decreased, and Fas and bax changed over time after operation. Conclusion Apoptosis maybe significantly positive correlated with the degrees of damage of the acute pancreaticoduodenal allograft rejection, and the apoptotic index maybe valuable to estimate the damage. FasL and bcl-2 were significantly related to the impairment of acute pancreatic allograft rejection as well. Duodenum biopsy may contribute to the early diagnosis of the rejecting transplanted tissues.
