垂体后叶素和硝酸甘油联合治疗食管静脉曲张破裂大出血

３０例肝硬化食管静脉曲张破裂大出血患者，用垂体后叶素０．２～０．４Ｕ／ｍｉｎ连续静脉滴注和硝酸甘油含服联合治疗。结果表明，近期止血有效申达８０％，死亡率１０％；无一例出现严重心绞痛和心电图异常。     

化学发光免疫法检测粒细胞抗体IgG的研究

作者以ＡＢＥＩ－ＣｏＣｌ＿２－Ｈ＿２Ｏ＿２作为化学发光指示系统，用固相竞争法检测５８例白细胞减少症患者、４１例无白细胞减少症患者及３２例正常人等的粒细胞抗体ＩｇＧ。判断标准采用正常人血清化学发光强度指数法。实验结果表明，白细胞减少症患者血清中粒细胞抗体阳性率明显高于无白细胞减少症患者（Ｐ＜０．００５）。本法敏感性为４３．１％，特异性为９０．２％，准确性为６２．６％，是一种灵敏而准确的方法，能将粒细胞包被试管在室温下较长时间保存，以供临床监测粒细胞抗体，大大缩短检测时间。     

Chronic Kidney Isograft and Allograft Rejection

In this study antigen-independent factor in the pathogenesis of chronic rejection of organ transplants was examined.Kidney isografts and allografts were transplanted orthotopically into bilaterally nephroectomized rat recipients and studied functionaaly,morphologically and immunohistologically,at serial intervals up to 52 weeks after transplantation.Allograft recipients developed progressive proteinuria after 12 weeks,with gradual renal failure ultimately leading to death.At the same time,morphological changes,including progressive arteriosclerosis and glomerulosclerosis ,tubular atrophy and interstitial fibrosis,developed.Immunohistologically,macrophages infiltrated glomeruli during this period and cytokines became unregulated.Our results showed that antigen-independent functional and morphological changes occurred in long-tern kidney isografts and mimicked those appearing much earlier in allografts that reject chronically.Initial injury and extent of functioning renal mass is suggested to be important factor for such late changes.     

深圳口岸入出境人员血清乙型肝炎病毒表面抗原检测分析

目的 了解深圳口岸入出境人员乙型肝炎病毒感染情况.方法 采用酶联免疫吸附试验(ELISA)检测受检人员血清HBsAg,并分析比较各类人员的HBsAg阳性率. 结果本次受检人员HBsAg阳性率为9.61%,其中台湾籍人员的HBsAg阳性率最高(为13.80%),其次是香港籍人员(10.94%)和交通员工(10.47%)以及大陆出国人员(6.99%),外籍人员最低,仅2.80%. 结论我国乙型肝炎病毒感染率仍较高,要注意加强乙肝知识的宣传,强化乙肝有防治和监测.     

Point mutation in the parkin gene on patients with Parkinson’s disease

Summary To investigate the distribution of possible novel mutations from parkin gene in variant subset of patients with Parkinson’s disease (PD) in China and explore whether parkin gene plays an important role in the pathogenesis of PD, 70 patients were divided into early-onset group and late-onset group; 70 healthy subjects were included as controls. Genomic DNA from 70 normal controls and from those of PD patients were extracted from peripheral blood leukocytes by using standard procedures. Mutations of parkin gene (exon 1–12) in all the subjects were screened by PCR-single strand conformation polymorphism (SSCP), and further sequencing was performed in the samples with abnormal SSCP results, in order to confirm the mutation and its location. A new missense mutation Gly284Arg in a patient and 3 abnormal bands in SSCP electrophoresis from samples of another 3 patients were found. All the DNA variants were sourced from the samples of the patients with early-onset PD. It was concluded that Parkin point mutation also partially contributes to the development of early-onset Parkinson’s disease in Chinese.

幼儿园824名3－6岁幼儿肝功能、乙肝表面抗原检测结果分析

为了解幼儿的肝功能和ＨＢｓＡｇ携带情况，我们于１９９１年肝炎发病高峰季节对我县四所幼儿园共８２４名幼儿进行了ＡＬＴ、ＴＴＴ、ＺｎＴＴ、ＨＢｓＡｇ检测。结果ＡＬＴ、ＴＴＴ均升高１例，有体征；ＡＬＴ单项升高６例，无症状；ＨＢｓＡｇ阳性５８例，其中９例ＡＬＴ升高，４例ＴＴＴ升高。幼儿园是幼儿集中的地方、同吃、同住、接触密切，对ＨＢｓＡｇ阴性者接种乙肝疫苗，对ＡＬＴ升高者不能忽视以免发生肝炎流行。     

变应性亚败血症33例报告

本文报告３３例变应性亚败血症，均以发热起病，伴有一过性皮疹和／或关节、肌肉酸痛，实验室检查以白细胞总数明显增高、血沉显著增快和粘蛋白增多为主要特点。本组病例初诊误诊率为８２．８％，起病至确诊时间平均４８ｄ，提示本病早期确诊较难，应提高对本病的充分认识。     

改进虎杖、鸡血藤炮制方法的研究

对虎杖、鸡血藤作了切制、干燥时间和成品、主要成分及水浸出物的比较。结果表明,趁鲜切片优于传统切块、再切片,既能提高饮片的规格质量和成分含量,亦能减少重复劳动,节约能源,避免药材的浪费。
