上肢屈曲性旋转撕脱离断伤的形成及功能挽救

目的探讨上肢轴向屈曲性旋转撕脱离断伤的形成以及侧胸和背部组织在功能挽救中的应用方式和疗效。方法2000年7月～2003年9月共收治6例上肢轴向屈曲性旋转撕脱离断伤患者,所有病例行一期再植或寄养再植。术后肩关节外展90°、肘关节屈曲100°位石膏或支具固定,6周后去除固定行功能锻炼。结果6例患者再植均顺利成活,随访3个月～2年,术后肩关节外展50°～90°,前屈50°～70°,后伸20°～30°,内收20°～40°;肘关节屈曲100°～140°,伸-20°～0°;重建术后3个月时屈肘肌力达Ⅳ～Ⅴ级。结论充分利用侧胸和背部组织特点进行分期、分层手术,解决创面覆盖和功能重建互相干扰的矛盾,是挽救严重轴向屈曲性旋转撕脱离断伤上肢,恢复其外形和功能的可靠方法。     

ENDOSCOPIC MUCOSAL RESECTION AND SUBMUCOSAL DISSECTION METHOD FOR LARGE COLORECTAL TUMORS

The goal of endoscopic mucosal resection (EMR) is to allow the endoscopist to obtain tissue or resect lesions not previously amenable to standard biopsy or excisional techniques and to remove malignant lesions without open surgery. In this article, we describe the results of conventional EMR and EMR using an insulation‐tipped (IT) electrosurgical knife (submucosal dissection method) for large colorectal mucosal neoplasms and discuss the problems and future prospects of these procedures. At present, conventional EMR is much more feasible than EMR using IT‐knife from the perspectives of time, money, complication, and organ preservation. However, larger lesions tend to be resected in a piecemeal fashion; and it is difficult to confirm whether EMR has been complete. For accurate histopathological assessment of the resected specimen en bloc EMR is desirable although further experience is needed to establish its safety and efficacy. Further improvements of in EMR with special knife techniques are required to simply and safely remove large colorectal neoplasms.     

Simultaneous orthotopic liver and heterotopic pancreas-duodenum transplantation in a diabetic patient with end-stage liver disease]

OBJECTIVE: To study the effect of combined transplantation of the liver and the pancreas in diabetic patients with end-stage liver disease, and explore the optimal surgical procedure. METHODS: Simultaneous orthotopic liver and heterotopic pancreas-duodenum transplantations were performed in a patient diagnosed as having chronic hepatitis B, hepatocirrhosis, hepatic cellular cancer, and insulin-dependent diabetes. Immunosuppression therapy utilized prednisone, tacrolimus (FK506), mycophenolate mofetil (MMF), and simulect. The function of the liver graft, serum amylase and lipase, blood glucose, and C-peptide were monitored after transplantation. RESULTS: Insulin was withdrawn at the 6th day after operation, good liver allograft functional recovery was achieved, without such complications as pancreatitis, thrombosis, and localized infections. CONCLUSION: End-stage liver disease with concomitant insulin-dependent diabetes is the indication for combined liver-pancreas transplantations, for which simultaneous orthotopic liver and heterotopic pancreas-duodenum transplantations may constitute the optimal surgical approaches as the primary choice.

Differential etiology of posttraumatic stress disorder with conduct disorder and major depression in male veterans.

BACKGROUND: Epidemiologic studies reveal that posttraumatic stress disorder (PTSD) is highly comorbid with both conduct disorder and major depression in men. The genetic and environmental etiology of this comorbidity has not been examined. METHODS: Data were analyzed from 6744 middle-aged male-male monozygotic and dizygotic twins from the Vietnam Era Twin Registry. Conduct disorder, major depression, and PTSD were assessed via telephone interview using the Diagnostic Interview Schedule for the DSM-III-R in 1992. Structural equation modeling was used to estimate additive genetic, shared environmental, and individual-specific environmental effects common and specific to conduct disorder, major depression, and PTSD. RESULTS: The association between conduct disorder and PTSD was explained primarily by common shared environmental influences; these explained 10% (95% confidence interval: 6%-17%) of the variance in PTSD. The association between major depression and PTSD was largely explained by common genetic influences; these explained 19% (95% confidence interval: 11%-26%) of the variance in PTSD. CONCLUSIONS: Our findings suggest that different etiologic mechanisms explain the association of conduct disorder and major depression with PTSD in male veterans. If replicated in other populations, results suggest research aimed at identifying specific genetic and environmental factors that influence PTSD may benefit from starting with those that have been more consistently and strongly associated with major depression and conduct disorder.     

内皮素在阻塞性黄疸早期门静脉高压症中的作用

目的初步探讨阻塞性黄疸早期门静脉高压的机制。方法将大鼠分为胆管结扎组（B）与假手术组（A），分别于术后3、7、14d比较两组的游离门静脉压力（FPP）、血浆和肝组织内皮素（ET）浓度。结果胆总管结扎7d后门静脉压力显著高于对照组；胆总管结扎后各时段ET水平均显著高于对照组；门静脉压力与血浆ET、肝组织ET呈正相关。结论阻塞性黄疸早期即有门静脉压力的升高，它可能是体内ET水平升高致肝窦阻力增加的结果。
