Objective To systematically review the effectiveness of amiodarone in treating repurfusion arrhythmia (RA) after thrombolytic therapy for acute myocardial infarction (AMI), so as to provide high quality evidence for formulating the rational thrombolytic therapy for AMI. Methods Randomized controlled trails (RCTs) on amiodarone in treating RA after thrombolytic therapy for AMI were electronically retrieved in PubMed, EMbase, The Cochrane Library (Issue 3, 2012), CBM, CNKI, VIP and WanFang Data from inception to January, 2013. According to the inclusion and exclusion criteria, two reviewers independently screened literature, extracted data, and assessed quality. Then RevMan 5.1 software was used for meta-analysis. Results A total of 5 RCTs involving 440 patients were included. The results of meta-analysis suggested that, compared with the blank control, amiodarone reduced the incidence of RA after thrombolytic therapy in treating AMI (RR=0.60, 95%CI 0.48 to 0.74, Plt;0.000 01) and the incidence of ventricular fibrillation (RR=0.47, 95%CI 0.26 to 0.85, P=0.01). It neither affected the recanalization rate of occluded arteries after thrombolytic therapy (RR=1.00, 95%CI 0.88 to 1.15, P=0.94) nor decreased the mortality after surgery (RR=0.33, 95%CI 0.10 to 1.09, P=0.07). Conclusion Current evidence indicated that, amiodarone can decrease the incidence of RA. Unfortunately, the mortality rate can’t be reduced by amiodarone. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion
Objective To discuss the early diagnosis and surgery of intestinal necrosis caused by superior mesenteric venous thrombosis (SMVT). Methords The clinical data of 32 patients with intestinal necrosis caused by SMVT were reviewed retrospectively and analyzed, which included 6 cases of primary SMVT, 26 cases of secondary SMVT, 9 cases with pylethrombosis, 24 patients had been dignosed definitely as SMVT by imageology examination before surgery. All the patients accepted surgery therapy, within which 9 patients accepted Fogarty catheter, and anticoagulation and thrombolytic therapy were administrated postoperatively. Results All patients had recovered except for one with short bowel syndromle and one died. Conclusions SMVT is a rarely ischemic intestinal disease, which has complicated pathogenesis and difficulty in early diagnosis. Intestinal necrosis often occurs as a result of delayed treatment and the effective way is to cut off necrotic intestines in time. Intra-and postoperative anticoagulation and thrombolytic therapy could reduce recurrency effectively.
目的 总结颈动脉体瘤的诊断和外科手术治疗的经验。 方法 分析我院1991年9月至2009年2月期间手术治疗的16例颈动脉体瘤患者的临床资料。 结果 术前均行彩色多普勒超声检查,9例行CT检查,6例行数字减影血管造影检查。3例首诊时误诊为其他疾病。11例行单纯瘤体切除; 5例采用大隐静脉行颈动脉重建。术后1例出现声音嘶哑,1例出现伸舌右偏,1例出现呼吸困难。10例获得7个月~15年(平均67个月)随访,未见复发和转移。 结论 临床医师应提高对颈动脉体瘤的认识,注意选择合适的检查方法以免误诊,外科手术切除是首选的治疗措施,大隐静脉重建颈动脉是一种较安全、有效的治疗方法。
目的 探讨肢体假性动脉瘤的病因、发病机理以及手术方式的选择,评价各种手术的治疗效果,以提高对假性动脉瘤的诊治水平。方法 30例假性动脉瘤患者(股动脉18例,腘动脉7例,肱动脉2例,桡动脉3例),其中8例为感染或破裂性假性动脉瘤,1例肢体坏死。30例患者均行外科手术治疗,其中11例行假性动脉瘤破口修补术,2例行股动脉结扎术,2例行血管端端吻合术,8例行自体大隐静脉移植术,6例行人工血管移植术,1例行截肢术。结果 30例患者术后恢复顺利,除1例行下肢截肢术外,其余29例术后效果良好。随访7个月~8年,平均(4.4±2.3)年; 行人工血管移植术者4例移植段发生血栓,经溶栓治疗后好转,其余血供状况良好。结论 外科手术治疗肢体假性动脉瘤是一种有效的方法。
ObjectiveTo detect the inhibitory effect of early growth response gene-1 DNA enzyme (EDRz) on proliferation of vascular smooth muscle cell (VSMC) and intimal hyperplasia, and confirm the effect of gene therapy on stenosis and occlusion after vein transplantation. MethodsEDRz was constructed, and autogenous vein graft model was established with Wistar rats, transplanting the right jugular vein to infra renal abdominal aorta by microsurgical technique. EDRz was transfected to the graft veins and the vein graft samples were harvested at hour 1, 2, 6, 24 and on day 3, 7, 14, 28, 42 after grafting, 10 Wistar rats were randomly selected in every time. The expression of EDRz in transfected vein graft was detected by fluorescent microscope. Egr-1 mRNA was measured by reverse transcription-PCR (RT-PCR) and in situ hybridization, respectively. The protein expression of Egr-1 was detected by Western blot and immunohistochemistry, respectively. HE stained vein grafts were observed under microscope. Results① The results of EDRz transfected vein graft: At hour 1 after grafting, EDRz was mainly located in adventitia, tunica media, and partial endothelial cells of vein graft; At hour 2, 6, and 24, EDRz was located in tunica media of vein graft; and on day 7, it was mainly located in intima of vein graft. There wasn’t EDRz in vein grafts on day 14, 28, and 42. ② The results of expression of Egr-1 mRNA: Detection by RT-PCR: At hour 1 after transfecting, the expression of Egr-1 mRNA arrived at the peak, and declined at hour 2, 6, and 24. The expression was tenuity on day 3. Egr-1 mRNA expression was not found on day 7, 14, 28, and 42. The expression of Egr-1 mRNA at hour 1 was significantly higher than that of the other time point (Plt;0.01). The result of in situ hybridization was coincident with RT-PCR. ③ The results of expression of Egr-1 protein: The result of Western blot: There was no expression of Egr-1 protein in normal veins. At hour 2 after grafting, expression of Egr-1 protein was found, and declined at hour 6, 24, and on day 3. There was no expression of Egr-1 protein at hour 1, and on day 7, 14, 28, and 42. The expression of Egr-1 protein at hour 2 was significantly higher than that of the other time point (Plt;0.01). The result of immunohistochemistry was coincident with Western blot. ④The degree of VSMC hyperplasia and intimal thickness were lighter in EDRz transfected vein grafts than that in nottransfected vein grafts contemporarily. ConclusionsEDRz could reduce the expression of Egr-1 in autogenous vein graft, and could effectively restrain VSMC proliferation and intimal hyperplasia, and prevent vascular stenosis and occlusion after vein grafting.
