Intraoperative coronary venography for portal hemodynamic observation in the procedure of combined portozygos disconnection

Since 1986, intraoperative coronary venography was performed on 24 patients before and after undergoing portoazygos disconnection for portal hypertension. Before the disconnection the portal vein was found to be communicated with cardial and esophageal veins by two pathways, i.e. from the esophageal branches of the coronary vein to the esophageal varices, and from the gastric branches of the coronary vein to the esophageal varices by way of the gastric intramural venula. The portal blood flow was postulated to be hepatofugal because the portal trunk could not be seen on the venography. Coronary venography done after the disconnection found no pericardial and esophageal varices but the portal vein with hepatoportal blood flow. The authors come to the conclusion that the operation has the advantage of both complete disconnection between the portal vein and the cardio-esophageal varices, thus preventing the varices bleeding, and increasing hepatic blood flow.     

联合断流术治疗食管静脉曲张出血的临床研究及远期疗效观察

自1981年1月以来,行联合断流术治疗门脉高压症食管静脉曲张出血102例,手术死亡率为6.9%。随访1～8年的生存率为85.7%,食管静脉曲张减轻或消失者为90%,未发现肝性脑病症状。远期死亡9例(14.3%),再出血4例(6.3%)。资料表明,这种手术既阻断了胃外又阻断了胃壁内的门-奇静脉交通血流,止血效果肯定而持久。由于未降低门静脉压力,故有利于维持肝脏的血流灌注。肝功能状况是决定治疗效果的主要因素。文章提出了选择手术适应证的条件。

综合、改良了分别分型的方法，建立了红细胞同工酶ＡＤＡ一ＥＡＰ一ＡＫ１同步电泳分型方法，为ＡＤＡ，ＥＡＰ和ＡＫ１３种红细胞同工酶在法医学鉴定中更广泛的应用，提供了一种可靠、经济、实用的方法。     

中国南方六省各民族体质特征及相互关系的研究

应用多元分析法对中国南方２６个民族组的体质特征进行分析比较。南方中国人显示出面貌头型比例适中，但绝对值较小，身体较瘦小的基本特点。面部轮廓因子、头部形态因子和体型因子是区分他们体质特征的简便而主要的因素。     

自体造血干细胞采集的护理

[目的]为进行自体外周血造血干细胞移植的病人提供优质护理，采集足够数量的造血干细胞，降低术中及术后不良反应。[方法]采用COBE Spectra血细胞分离机采集造血干细胞在采集前严密观察病人心理和血常规的变化，维持病人心理状态的稳定，掌握干细胞采集的最佳时机；术中严密观察生命体征、意识、四肢口唇是否有麻木感；术后监测病人外周的穿刺部位是否有出血，有无手足抽搐。[结果]20例病人均采集足够数量的造血干细胞，无不良反应发生：[结论]优质护理为自体外周血造血干细胞移植的成功奠定了基础。

体表胃电传导特性的研究

本文以胃钡餐X线照片为依据,选择胃体中央、胃体窦交界处和胃窦中央作为电极定位点,分别为E_1、E_2、E_3点,同步检测胃电图。实验结果表明:胃电慢波E_1先出现,呈现从E_1点向E_3点传导的现象;胃电慢波幅值E_1,E_2、E_3点餐前分别为274±55、554±196、726±145μV,餐后分别为294±41、606±188,801±240μV;试餐前及试餐后,各点胃电图优势频率均值之间差别无统计学意义(P>0.05)。提示体表胃电存在传导特性,传导方向从胃体中央扩播至胃窦中央。越近胃窦波幅越高,但优势频率不变。     

外周神经动作电位记录中刺激伪迹的消除方法

<正> 记录外周神经动作电位的实验中往往有难以克服的刺激伪迹。特别所记录的外周神经比较短时,此问题更为突出。一般常用的消除刺激伪迹方法亦不易奏效。通过摸索,我们找到一种简单的消除方法。现介绍如下:     

Effect of baoshen wan on serum lipid peroxide levels in nephritis treated based on the differentiation-syndromes

This paper deals with the treatment of 22 cases of chronic nephritis with Baoshen Wan (protecting kidney pills) according to the differentiation of syndromes; the results showed that 3 cases had got perfect remission, 6 cases fundamental remission, and 10 cases partial remission; thus its effective rate reached to 86.4%. Before treatment, the mean value of serum LPO of the 22 patients was 4.44 +/- 0.099 (means +/- S means, mumol/L), which compare with the normal value (3.69 +/- 0.075), P less than 0.05. After treatment, the serum LPO level was lowered to 3.95 +/- 0.11, P less than 0.05. It suggested that Baoshen Wan could disperse the free radical and lower the serum LPO level in the patients with chronic nephritis.     

电针内关穴对窦房传导功能的影响及其意义

采用直接窦房传导时间（ＳＡＣＴｄ）为指标，对１０例窦房结功能正常者进行了针刺前、针刺及固有心率（ＩＨＲ０）期间ＳＡＣＴｄ测定，以探讨电针内关穴对窦房传导功能的影响及其意义。结果表明：电针与ＩＨＲ０期间ＳＡＣＴｄ较对照期显著缩短（Ｐ〈０．０１；Ｐ〈０．００１）。自主神经阻滞后，电针该穴不能使ＳＡＣＴｄ进一步缩短（Ｐ〉０．０５）。提示；以内关穴为主的电针刺激能改善正常窦房传导功能，其作用似与自主神经中
