小腿后部各区穿支间的关系与皮瓣设计

Objective To study the anastomotic relationships of perforators in each zone of the poste-rior leg and design perforating flaps for clinic. Methods Six fresh cadavers underwent a whole body, intra-arterial injection of a lead oxide and gelatine preparation. The posterior part of leg is divided into upper, mid-die and below equal parts, Observe topography of the perforating branches in every district by layer, and mea-sured their location, diameter, course, branches and anastomosis pattern. Radiographs of tissue specimens were digitally analyzed. Results There were 13 perforators that diameter≥ 0.5 mm, the average external diameter was 0.8 mm. The areas of each perforator supplied was average 38 cm2. Perforators from popliteal artery was identified an area 4 cm wide, around the intersection of two lines, a line drawn between the medial and lateral epicondyles of the femurs, and the midline of posterior leg. The areas of the every perforator sup-plied was 55 cm2. These vessels were large in diameter and create multiple true anastomoses with the perfora-tors from the posterior tibial artery or fibular artery. Perforating branches were small in the below part, a long perforator chain comprised of two to three perforators accompanies the Achilles tendon. Conclusion The perforator flaps deviced by perforators from the posterior leg may be transplanted to the lower limbs and the other part of the body. The perforators located in the middle zone of the leg are larger. Free posterior tibial or peroneal perforator-based flaps are reliable, relatively large, and have thin flaps. The upper and lower zones were the larger donor site for the proximal or distally pedicled perforator flap harvest.     

铅中毒误诊6例

铅中毒近年来已少见,特别是典型的则更少。最近我们在乡镇企业调查中检出铅中毒9例,经2～12个疗程依地酸钙钠治疗已愈;但有6例曾在地、市医院误诊为肠梗阻1例,消化道穿孔1例,胃炎4例。现将病例报告如下。     

桡神经及其深支的血供

在25具成人尸体(50例)上,观测了桡神经及其深支的血供。桡神经的营养动脉平均为4.36±0.26支,营养动脉和来源动脉的外径平均为0.38±0.08mm和1.65±0.05mm。桡神经深支的营养动脉平均为1.72±0.16支,营养动脉和来源动脉的外径平均为0.29±0.01mm和1.91±0.07mm。     

渭南市10年食物中毒动态分析

本文通过对渭南地区1986～1995年食物中毒情况进行动态分析,总体表明10年内食物中毒呈下降趋势,但中间有波动。食物中毒多发生在第二季度和第三季度;人群分布的特点是农村高于城市;中毒场所多为个体摊贩和农户;引起中毒的食物多为动物性食品,微生物因素引起的高于化学性引起的食物中毒。     

医学院校科技协作模式初探

在我国以计划经济体制为主的昨天,科技活动主要是接受上级下达的计划任务,科技协作曾经发挥了重要作用,但在建立和完善社会主义市场经济体制的今天,如何进一步搞好科研协作,则是摆在科管人员面前的一项紧迫而艰巨的任务。作为我国科技力量的一支主力军,高校如何运用市场经济机制来形成合理的人才流、物资流、信息流和资金流,则是关系到高校科技能否迅速发展,取得突破的重大问题。一、目前常见的科技协作形式科技协作是高校科技活动的重要形式,但已往大多停留在以教研室为基本合作单位的基础上,带有明显的“以教学为中心”的时代特…     

虚证的病机特点及其治法新探

长期以来，在有关虚证的病机及其治法问题上，一直认为虚可导致人体脏腑功能减退，防御能力低下，治疗以“虚者补之”为原则，具体以补五脏气血阴阳为法。笔者认为，这仅是虚证病机及其治法的一个方面，而实际上，虚证尚有深层次的病机及其特点，治疗上也有其针对性。兹就这一问题探讨如下。14证的病机特点众所周知，精气血津液是构成人体和维持生命活动的基本物质，其盛衰直接关系到人体的强弱。而影响正气强弱的因素，包括外感、内伤及久病正气不复等，都可损伤人体的精气血津液，日久形成如《素问·通评虚实论》所说的“精气夺则虚”。若…

正交函数分光光度法测定甘草浸膏和甘草流浸膏中甘草酸的含量

用氧化铝柱吸附处理样品,用正交函数分光光度法测定甘草浸膏和甘草流浸膏中甘草酸的含量,方法简单,仪器要求不高,易于推广。经测定甘草浸膏平均回收率为98.27％,RSD=1.57％(n=3),甘草流浸膏平均回收率为98.92％,RSD=1.31％(n=3)。
