自杀行为及其干预的研究进展

自杀已经成为一个世界范围内的重大公共卫生问题。中国的自杀特征具有独特性。自杀行为的发生往往是内在因素与外部因素相互作用的结果，它与社会学、心理学、伦理学、生物学、精神病学等各方面密切相关。自杀原因虽然错综复杂，但我们要提高意识，认识到自杀是一种可以预防的公共卫生问题。     

基于变更模型的元数据在构件回归测试中的应用研究

本文针对Orso元数据方法的不足,对构件可能的变更进行了充分分析和分类,并按照分类情况对相关的构件变更处理方法进行了详尽的形式化描述,构造了构件变更模型,描述了每个变更的具体表现形式,论述了方法变更到构件接口变更的映射机制和算法,给出了算法实现的框架,并将这些理论模型应用到自主开发的构件RegisterStuGrade中,与没有元数据情况下的回归测试用例生成技术以及Orso方法进行回归测试用例数和回归测试运行时间两方面的分析和对比,给出了比较结果.     

Non-cultured cell transplantation in an ovine model of non-ischemic heart failure.

OBJECTIVE: Cell therapy may be a promising alternative or adjunct to current treatment modalities for ischemic heart failure. But little is known on the impact of myogenic cell transplantation in large animal models of non-ischemic cardiomyopathy. The aim of the present study was to explore whether an ovine model of toxin-induced heart disease could benefit from non-cultured skeletal muscle cell transplantation. METHODS: Sequential intracoronary injections of doxorubicin (0.75 mg/kg) were carried out every 2 weeks until echocardiographic detection of myocardial dysfunction. Sheep were then randomly assigned to either non-cultured cell transplantation (n=8) or placebo injection (n=5). For the cell therapy group, a skeletal muscle biopsy (about 10 g) was explanted from each animal approximately 3h before grafting. After thoracotomy, 20 epicardial injections were carried out. The animals were assessed one last time before sacrifice, 2 months after the thoracotomy. Cells were tracked with cmDiI (red fluorescence) and characterized with immunohistochemistry with monoclonal antibodies to a fast skeletal isoform of myosin heavy chain. RESULTS: Two months after intramyocardial grafting, tissue Doppler imaging and conventional echocardiographic assessment of the groups showed a marked improvement in the non-cultured cell therapy group. Ejection fraction (EF) (p<0.05) as well as systolic endocardial velocities (p<0.01) improved versus the placebo group. CmDiI and skeletal myosin heavy chain expression was detected in all animals at 2 months after implantation confirming engraftment of skeletal muscle cells. CONCLUSIONS: In conclusion, our data indicate that non-cultured muscle cell transplantation is feasible and may translate into a functional benefit in an ovine model of dilated heart failure.     

硫酸奈替米星葡萄糖注射液联用复方维生素注射液致呼吸困难伴腰痛1例

1临床资料 患者，女，43岁，因车祸致右胫腓骨骨折入住我院创伤骨科，一般情况良好，无食物、药物过敏史，入院后行腓骨复位固定术，3d后，伤口红肿并有脓液渗出，为预防和控制感染，静脉滴注硫酸奈替米星葡萄糖注射液每日200mL（每瓶100mL，硫酸奈替米星10万u，约相当于0．1g，葡萄糖5．0g，山东鲁抗辰欣药业有限公司，批号0803155209）分两次滴注，中间滴注含有4mL复方维生素注射液的10％葡萄糖注射液500mL（四川美大康佳乐有限公司，批号080125124）。     

在深静脉血栓—肺栓塞病程中腔静脉滤器的应用价值分析

目的：探讨腔静脉滤器(Vena cava filter VCF)在深静脉血栓(Deep venous thrombosis DVT)—肺栓塞(Pulmonary embolism PE)病程中的应用价值。方法：结合本组25例高危深静脉血栓一肺栓塞患者，对其中24例置放5种构型的永久型或临时型下腔静脉滤器(IVCF)26枚的临床疗效、影响病程与预后因素及病生理改变，复习文献分析讨论。结果：DVT有可能脱落导致PE或致死性肺栓塞；置放IVCF可有效预防肺栓塞，早期进行溶栓治疗，改变预后。结论：严格按适应证植入IVCF，对DVT—PE的早期治疗和预防致死性肺栓塞有重要意义，但其应用价值需进行综合评价和进一步探讨。     

α-平滑肌肌动蛋白和β-肌动蛋白在瘢痕组织中的表达

目的 探讨α-平滑肌肌动蛋白(α-SMA)和β-肌动蛋白(β-actin)对增生性瘢痕形成的可能作用。方法 采用荧光定量PCR法检测10例增生性瘢痕和10例正常皮肤组织中α-SMA和β-actin的表达水平。结果 增生性瘢痕组织中α-SMA和β-actin表达水平均高于正常皮肤组织,差异有统计学意义(P<0.01)。结论 α-SMA和β-actin在瘢痕增生中起重要作用;由于β-actin在瘢痕组织和正常皮肤中的不恒定性,建议在瘢痕的mRNA定量研究中不作为内参照物。     

骨科手术患者术中自体血回输的临床观察

目的:探讨骨科手术患者术中自体血回输的临床效果,以期能减少异体血的用量。方法:将骨科择期手术患者,术中随机分为自体血回输组,及异体血输血组,比较两组术后24h伤口引流量、血常规等情况。结果:两组患者手术顺利,自体血回输组术中均未用异体血,但少数患者术后发生低凝状态,输入异体血。结论:术中自体血回输能减少异体血输入量,但须适当补充新鲜血浆和凝血因子。     

Giant dermoid associated with foot duplication

After resection at birth of an accessory left foot, a white male infant was followed up for a slowly enlarging posterior calf mass of the same leg. When the patient was 8 years old, the mass was thought to have enlarged sufficiently to warrant excisional biopsy. Histologic examination of the tumor was consistent with the diagnosis of a dermoid cyst, revealing a lesion lined with stratified squamous epithelium and containing cutaneous adnexal structures represented by eccrine sweat glands. A congenital dermoid in the extremities is unusual. The prognosis following removal is good, and recurrence is rare.
