动静脉双吻合建立血透永久性血管通路

目的探索动静脉内瘘术的新方法,提高细小血管患者的动静脉内瘘术成功率。方法针对32例头静脉主干直径小于2 mm者,常规游离出桡动脉和头静脉及其分支,分别结扎头静脉主干及其分支远端,横断桡动脉,将桡动脉远、近端分别与头静脉主干及分支用7-0丝线行端端间断缝合。结果手术成功26例,失败6例,原因为术后血栓形成4例,术后瘘口狭窄1例,头静脉延迟成熟1例;成功26例术后2～3个月使用内瘘透析,血流量达到200 ml/min以上;所有患者远端手部未发生缺血和窃血综合征,未发生心衰和心衰加重。结论动静脉双吻合术式适合于头静脉细小、掌弓血管通畅的拟造瘘患者,此法可以加大头静脉的血流量,增加细小静脉血管扩张成熟的机会。     

阿尔茨海默病患者脑白质束铁沉积的磁共振相位成像

目的：利用磁共振相位成像和扩散张量成像(DTI)技术,探讨阿尔茨海默病(AD)患者的脑白质束损伤与相应白质束铁沉积的相关性。方法：对25例AD患者及20例年龄相匹配的健康老年志愿者进行MR扩散张量成像及相位成像。DTI数据经后处理生成平均扩散系数(MD)和部分各向异性(FA)图,分别测量穹窿、胼胝体膝部、胼胝体压部、双...     

囊型包虫病药物新剂型研发及新药开发现状

囊型包虫病(CE)由细粒棘球蚴感染引起,可累及全身器官。手术是治疗CE的主要方法。随着技术发展、精准手术及无瘤手术标准的引用,CE的手术禁区越来越小,但仍有许多患者因为无法手术而只能选择药物保守治疗。然而,目前治疗CE的药物选择很少,仅有苯并咪唑一类有较确切的疗效。现回顾目前国内外CE的药物治疗研究进展,为药物开发研究及临床药物应用选择提供参考。     

彩超对甲状腺肿瘤的分析

目的 探讨彩超对甲状腺肿瘤诊断情况.方法 采用回顾性分析的方法,分析我院收治的甲状腺肿瘤患者临床资料,观察患者彩超诊断和手术病理结果,不同甲状腺肿瘤血流指标情况.结果 甲状腺腺瘤51例,误诊5例,诊断符合率90.2％,结节性甲状腺肿27例,误诊4例,诊断符合率85.2％,2例甲状腺癌,诊断符合率100％,甲状腺癌者的峰值流速和阻力指数均高于甲状腺腺瘤和结节性甲状腺肿患者,P＜0.05,差异有统计学意义.结论 彩色超声作为诊断甲状腺肿瘤的一种手段,不仅具有较高的诊断准确率,同时可以很好的观察甲状腺肿瘤血流情况,为临床明确诊断提供可靠理论依据,值得临床推广应用.     

超声弹性成像技术及其临床应用研究进展

超声弹性成像作为近年来迅速发展的成像技术,能够反映声阻抗相同的不同组织的弹性模量特点,由于其提供了一种独特的观察方法,一经出现便受到广泛关注,将其与传统的影像学检查手段(如常规超声、CT、磁共振成像)相结合可以有效地提高病变诊断的准确度。在此就超声弹性成像的基本原理与技术方法及其临床应用的国内外研究现状进行介绍,并展望其发展趋势。     

舌鳞癌细胞微环境对小鼠髓源性树突状细胞生长分化的影响

目的:探讨舌鳞癌微环境对小鼠髓源性树突状细胞生长分化的影响.方法:小鼠骨髓前体细胞,在含重组小鼠粒细胞-巨噬细胞集落刺激因子和重组小鼠白介素-4培养体系中体外培养.实验组在上述培养液中再加入Tca8113培养上清液模拟肿瘤微环境(Tumor microenvironment,TME);对照组不加Tca8113培养上清液...     

Research on Modern Nonlinear Dynamic Model of Five-Elements Theory

This article studied on five elements system and set general and strict model expectations combining with Traditional Chinese Medicine Zang-fu organs theory,in which absolute stable state,conditional stable state or transient stability and instability in mathematical models were corresponding to human healthy state,sub-healthy state(pathological plateau phase) and health deterioration state respectively.Model parameters were set up according to the mutual generation and restriction relations among five elements.The dynamic model of Five-Elements System was built,of which impulse responses were corresponding to human response under TCM treatment.Analyses of initial value and excitation response were conducted by numerical simulation and results turned out to meet the requirements of general model expectation:five elements system dynamic model had self-organization function;there existed only one non-global stable point and instability region in the five-dimensional space consisting of variables,in which instability was corresponding to pathological deterioration;system stable region was an unbounded domain and it included the stable sub-regions of special straight line-type,ray-type and line segment-type.Among those ray-types,some contained "Regression Peak" were classed as conditional stable regions while others as absolute ones.The existence of this peak indicates that our body must exceed a "Regression Threshold" when transiting from sub-healthy state(pathological plateau phase) to healthy state through self-regulation mechanism.Impulse excitation can reduce certain threshold and then increase the system health level,which is complied with the operating principle of Five-Elements System and the empirical rule of TCM clinical practice.This model has revealed qualitatively the inherent movement law of Five-Elements System and thus provides a new analysis tool for basic theoretical study on TCM.     

汶川地震后安县不同受灾地区女性受灾群众创伤后应激障碍(PTSD)的发生率及相关因素

目的:汶川地震震后6个月安县不同受灾地区女性受灾群众创伤后应激障碍(PTSD)发生率及其相关因素。方法:应用使用自编个人基本情况调查表、创伤后应激障碍症状清单平民版(PTSD Checklist-Civilian Version,PCL-C)调查表和标准化评定工具,对地震时在安县地区居住,在极重受灾乡镇、重受灾乡镇、一般受灾乡镇灾区女性受灾群众应用PCL-C调查表进行PTSD诊断检查及相关量表的测查,测定PTSD总的发生率,对比不同受灾乡镇影响因素。结果:完成调查共563名20～70岁女性人群中,PTSD总的发生率是19.54%,极重灾区、重灾区和一般灾区PTSD发生率分别为26.94%,18.85%,15.79%,均高于一般人群。影响因素为反复重现创伤性体验,持续性警觉性增高,持续的回避。极重灾区、重灾区和一般灾区这几种因素对比有显著性差异。结论:震后6个月女性受灾群众PTSD发生率较高,重灾区女性受灾群众尤其需要灾后心理干预工作的关注。
