Repair of bile duct defect with full-thickness vascularized jejunal patch

The use of a vascularized jejunal patch for the reconstruction of bile duct injuries is presented. The method has been used in 1 patient with a common bile duct stricture and in 1 patient with a noncircumferential bile duct defect. The procedure has the advantages of technical simplicity, primary mucosal coverage, lasting elasticity, and minimal risk for stricture formation.

Resumen Se presenta el uso de un parche vascularizado de yeyuno para la reconstrucción de lesiones del canal colédoco. Se reseca un segmento móvil del yeyuno lo suficientemente amplio para cubrir el defecto, asegurándose de que existe buena irrigación para el segmento, visualizando los vasos por transiluminación con luz ordinaria. La continuidad del intestino es restablecida mediante anastomosis término-terminal. Se utiliza la parte mesentérica del segmento intestinal, el cual es ascendido por vía retrocólica. Se sutura mucosa con mucosa con una sola capa de puntos separados de ácido poliglicólico 5-0. Se coloca un tubo-en-T para drenaje, el cual es retirado a las 6 semanas. El método ha sido utilizado en un caso de estenosis del colédoco y en un caso con un defecto circunferencial del mismo canal biliar. El procedimiento tiene la ventaja de la simplicidad técnica, la cobertura primaria de la mucosa, la elasticidad permanente y un mínimo riesgo de que se produzca estenosis.

Résumé L'emploi d'un patch jéjunal bien vascularisé pour traiter les blessures de la voie biliaire fait l'objet de l'article. La méthode a été utilisée pour un cas de sténose de la voie biliaire principale et un cas de plaie n'intéressant pas la totalité de la circonférence du canal biliaire. Elle a pour avantages sa simplicité technique et le fait qu'elle assure une couverture muqueuse, sa persistante élasticité et le fait qu'elle présente un risque réduit de sténose.

     

2005～2006年江西省血吸虫病疫情监测点螺情调查结果分析

目的分析2005～2006年江西省12个国家级血吸虫病疫情监测点螺情调查结果,掌握各监测点钉螺消长情况。方法依据《全国血吸虫病疫情监测点方案》,对各监测点钉螺孳生环境与可疑环境进行调查,比较两年的各项螺情指标。结果2006年12个监测点的有螺面积较2005年下降17.27%,但各监测点有螺面积下降幅度不相一致,有10个监测点查出有阳性钉螺分布;另外各监测点活螺密度、阳性螺密度也有较大波动。结论各监测点螺情依然严重,应加强控制钉螺的防治力度。     

心脾综合征的多普勒超声心动图诊断

目的:探讨多普勒超声心动图对心脾综合征的诊断价值,分析其心脏伴随畸形漏诊及误诊原因,提高对心脾综合征诊断的准确率。方法:本文总结了221例心脾综合征患儿的超声检测结果,并与其心血管造影或磁共振检查结果进行对照。结果:超声心动图诊断为心脾综合征与心导管或磁共振结论符合者199例(占90.0%),诊断不符合者22例(占10.0%)。结论:多普勒超声心动图可以较准确地诊断心脾综合征,但对其心脏伴随畸形检出的准确率尚待进一步提高。

Role of the transient outward current (Ito) in shaping canine ventricular action potential – a dynamic clamp study

Transmural electrical dispersion determines the repolarization sequence across the ventricular wall, and plays an important role in the development of arrhythmias under pathological conditions. While it is clear that the transmural gradient of the transient outward current ( I _to) underlies the dramatic difference in phase 1 repolarization across the ventricle, its contribution to the transmural action potential duration (APD) dispersion is not clear. We investigated this problem using the dynamic clamp technique in canine ventricular myocytes. The dynamic clamp allows quantitative 'insertion' of simulated conductances in real, biological cells, bridging pure computer modelling and experimental electrophysiology. 'Insertion' of an epicardial level of I _to in endocardial cells produced a prominent phase 1 repolarization and a 'spike-and-dome' action potential morphology, but did not significantly affect the APD. Increasingly larger I _to densities prolonged, and then dramatically shortened the endocardial APD. We also used the dynamic clamp to subtract, or 'block' the native I _to in epicardial cells. Such 'blockade' eliminated the epicardial action potential notch, but had no significant effect on the APD. We conclude that I _to, while being a key regulator of phase 1 repolarization, does not significantly affect the APD of canine ventricular myocytes, and that the I _to gradient is not a significant contributor to the transmural APD dispersion in the canine ventricle. By allowing computer simulation on a biological background, the dynamic clamp is a new and effective tool to study the ionic basis of the electrical properties of cardiac cells.     

腔内激光治疗大隐静脉曲张192例报告

目的 探讨腔内激光治疗大隐静脉曲张的疗效。方法 2004年7月～2006年3月我院对192例238条肢体大隐静脉曲张行高位结扎、激光烧灼静脉主干和小腿曲张静脉。小腿局部严重曲张的静脉团,另做切口做局部切除或点状抽拨。结果 本组一次治愈率96.2%（229/238）。9例9条肢体术后因仍有少量曲张静脉存在,局麻下行切除或再次激光治愈。114例大隐静脉主干及小腿局部条索状硬结、疼痛;9例皮肤灼伤。术后住院时间4～8 d,平均5.6 d。158例随访1～18个月,平均11.6月,未见复发。结论 腔内激光治疗大隐静脉曲张效果确切,创伤小。     

Association of the Platelet Glycoprotein Ⅰa C807T Gene Polymorphism With Risk of Myocardial Infarction in Chinese

Objectives To investigate the relationship of the GPIa C807T dimorphism to the risk of myocardial infarction (MI) in Chinese. Methods We did a case-control study including 100 patients and 110 controls with same race. An allele-specific polymerase chain reaction (PCR) was used for genotyping of C807T polymorphism. Results An apparent association was found between the T807 allele and MI among individuals younger than the mean age of 60 years (odds ratio,2.49; 95% confidence interval, 1.08 ～ 6.22 ). The T807 allele remained an independent risk factor for MI when age, sex, smoking, hypertension, diabetes, bodymass index, LDL-cholesterol and HDL-cholesterol were adjusted by logistic regression. Conclusions GPⅠa T807 appears to be an independent risk factor for MI.
