宫内发育迟缓儿的分娩方式与围产儿转归

对１５７例足月体重≤２５００ｇ宫内发育迟缓儿的分娩方式与围产儿Ｌ转归进行了临床分析。结果表明，新生儿出生体重愈低，围产儿死亡率、新生儿窒息率和新生儿并发症的发生率愈高。剖宫产组围产儿死亡率不仅没有下降，反而增加了新生儿窒息率和并发症的发生率。胎吸和产钳助娩组新生儿并发症的发生率明显升高。臀位助娩和臀位牵引的新生儿窒息率、并发症发生率及围产儿死亡率显著高于自然分娩组，故对宫内发育迟缓儿应加强围产保健和产时监护，尽量使其自然分娩；臀位儿以剖宫产为宜。

预缺血对培养乳鼠心肌细胞缺血再灌注损伤的延迟保护作用

观察了预缺血对培养乳鼠心肌细胞缺血再灌注损伤的影响。结果发现,经预缺血诱导的,Ｃ肌细胞超氧化物歧化酶（ＳＯＤ）活性升高,与缺血再灌注组（Ｉ－Ｒ）比较,经典预适应组（ＣＰＣ）和延迟预适应组（ＬＰＣ）乳酸脱氢酶（ＬＤＨ）释放减少,心肌细胞存活率升高,脂质过氧化减轻,膜流动性增加。提示：培养乳鼠心肌细胞存在延迟预适应,其机制与预缺血提高心肌细胞抗氧化酶的活性、增加缺血再灌注时自由基的清除有关。

Relationship between the acid-suppression efficacy of proton pump inhibitors and CYP2C19 genetic polymorphism in patients with peptic ulcer

Obiective To investigate acid-suppression efficacy of proton pump inhibitors(PPls) in relation to CYP2C19 genetic polymorphism on patients with peptic ulcer. Methods By an open, randomized and control trial, fifty nine patients with active peptic ulcer were randomly assigned to receive one of three PPIs on a single dose (20 mg of each drug): omeprazole group (n=19), rabeprazole group (n=20) and esomeprazole group (n=20). lntragastric pH was recorded 1 hour before and 24 hours after administration. CYP2C19 genotype was tested in all patients. Resuits The EMs/PMs ratio of each group was 16/3,17/3 and 17/3, respectively. The total time that intragastric pH＞4, time percent pH＞4 and median pH in PMs patients were significantly higher than those in EMs patients of omeprazole group (P＜0.05). But all these differences were not found in rabeprazole group and esomeprazole group. The pH of nocturnal acid breakthrough (NAB) in both rabeprazole group and esomeprazole group was higher than that of omeprazole group, while there was no significant difference between rabeprazole group and esomeprazole group. Gonclusion The acid-suppression efficacy of omeprazole is highly dependent on CYP2C19 genetic polymorphism, while CYP2C19 genetic polymorphism may have a little influence on the acid-suppression efficacy of rabeprazole and esomeprazole. The acid-suppression action of rabeprazole and esomeprazole is superior to omeprazole, especially on night acid secretion.

EFFECT OF ROSIGLITAZONE AND METFORMIN ON CLOMIPHENE CITRATE RESISTANCE IN WOMEN WITH POLYCYSTIC OVARY SYNDROME

Objective To evaluate the impacts of rosiglitazone and metformin on ovarian response, hirsutism and insulin action in women with polycystic ovary syndrome (PCOS). Methods Ninety women resistant to clomiphene citrate with PCOS were randomized, 40 cases to rosiglitazone group, 50 cases to meformin group. Rosiglitazone and metformon were administered for 6 months in combination with clomiphene citrate on cycle day 5th to 9th, respectively. The clinical evaluations were performed monthly. Reproductive hormone, serum glucose and insulin levels were observed before and after treatment. The data were analyzed using repeated analysis of variance (ANOVA). Results There were significant changes in reducing hirsutism score, serum testosterone level, LH/FSH ratio, and restoration of ovarian ovulation after metformin or rosiglitazone administration respectively (P<0.05). Insulin sensitivity was more significantly improved in the rosiglitazone group than in metformin group (P<0.05) After treatment. Homa IR and Homa β were decreased from 1.54±0.34 to 0.83±0.38 and from 5.83±0.55 to 4.95±0.54 (P<0.05) in the rosiglitazone group. The body mass index(BMI) was decreased from 25.30±3.64 to 23.83±2.32 in the metformon group (P<0.05). There were no significant changes in ovulation rate and pregnancy rate between groups (P>0.05). Conclusion Rosiglitazone can increase insulin sensitivity. Metformon may reduce BMI. They all restore regular menstrual cycles, increase pregnancy rate, and reduce testosterone and LH concentration in women with polycystic ovary syndrome.     

医学本科生学习成绩影响因素的调查分析

以医学系四年级学生临床综合考试成绩和操行总评得分为因变量，与性别、年龄、民族、血型、性格类型、心理年龄、气质、城乡等自变量进行单因素显著性检验、相关及多因素逐步回归分析。结果显示：临床综合考试成绩和操行总评得分分别在男、女性别中出现明显差异，即女性都高于男性（Ｐ均小于０．０００１）；在汉族与少数民族之间其差别也很明显，前者显著高于后者（Ｐ＜０．０００３和Ｐ＜０．０００２）。单因素相关及多因素逐步回归表明，临床考试成绩（Ｙ１）与操行总评得分（Ｙ２）、年龄（Ｘ２）、性别（Ｘ１）、民族（Ｘ３）之间依次出现不同程度的联系（Ｆ值的概率依次小于０．０００１、０．０００１、０．０１４５和０．０３１８）。操行总评得分（Ｙ２）与临床综合考试成绩（Ｙ１）、民族（Ｘ３）、性别（Ｘ１）、气质（Ｘ７）之间亦存在联系（Ｆ值的概率依次小于０．０００１、０．００１０、０．００３５和０．０３４６）。通过学生学习成绩和操行总评得分两因变量与诸多自变量出现差别的因素的研究，无疑对提高教学质量、改进教学方法、完善教学管理、开发学生智商、挖掘学习潜力、培养学生成为德、智、体全面发展的人才有着现实的指导意义。     

慢性肝病患者血清Ⅰ、Ⅲ型胶原变化及其意义

应用酶联免疫吸附试验（ELISA）检测了139例慢性肝病患者及30例正常对照血清Ⅰ、Ⅲ型胶原含量。结果发现，在慢迁肝、慢活肝及肝硬化各组其含量逐渐上升，Ⅰ型胶原及Ⅰ、Ⅲ型胶原比值能更好地反映肝纤维化程度。相关性分析表明二者与反映肝细胞损伤指标均不相关。提示Ⅰ型胶原及Ⅰ、Ⅲ型胶原比值是判定肝纤维化状况的较可靠指标。

肾衰口服液对实验大鼠腹膜透析效能及腹膜超微结构的影响

通过模拟腹膜透析的动物实验，观察了肾衰口服液（SSOL）对腹膜透析效能及腹膜超微结构的影响。大鼠分正常对照组、单纯透析液组（A）、合SSOL腹透组（B）。结果显示：①B组净超滤量、腹膜清除率与A组比较均显著增加（P＜0．05～0．005）；B组透析液中蛋白质含量高于A组，但差异无显著性意义（P＞005）。②B组腹膜间皮细胞及间皮细胞连接的损伤程度较A组为轻。提示SSOL能有效提高腹膜透析效能，并能拮抗高渗透析液保护腹膜间皮层结构的完整。     

保尔佳治疗晚期恶性肿瘤的临床观察

将76例晚期恶性肿瘤患者随机等分为2组：单纯化疗组及化疗加用保尔佳治疗组，以观察保尔佳的临床作用。结果：保尔佳治疗组有效率42．1％，体力状况改善老39．5％，外周血白细胞数正常者73．7％，均显著高于化疗组（分别为21．1％、15.7％和44．7％；P＜0．05、P＜0．025和P＜0．025）；毒副反应两组无显著性差异。提示保尔佳与化疗药物联合应用治疗晚期恶性肿瘤优于单纯化疗，并能改善患者的体力状况，减轻化疗所致的外周血白细胞数下降。     

绞股蓝总皂甙防治慢性肾功能衰竭的实验研究

为了观察绞股蓝总皂甙（GP）对慢性肾功能衰竭（CRF）的作用。用腺嘌呤灌胃建立大鼠CRF模型，并用GP进行防治。结果表明GP组大鼠肾功能明显改善，贫血明显纠正，和病理组大鼠比较差异显著（P＜0．01或＜0．05）。肾脏病理检查显示，GP组肾小球结构基本正常，间质纤维化不明显，而病理组病损严重，间质明显纤维化。提示GP具有改善肾功能、纠正肾性贫血、延缓CRF进展的作用。     

胎儿和幼儿跖趾骨血液供应的观察

采用微血管造影等方法,观察30例胎、幼儿跖趾骨的血供。结果表明:胎儿期跖趾骨骨干和两端软骨逐渐增大,出现滋养动脉和软骨管,幼儿期两端软骨逐渐变小,软骨管也逐渐消失。提示软骨管的出现与软骨块的大小有关,软骨管是胎儿软骨内的临时血管系统。跖趾骨血供特点:①跖趾骨血供的不均称性分布,即骺端软骨血供丰富,这与两端生长能力不同相适应;②远趾只骺端有软骨管分布,这与只骺端有生长能力相适应,说明跖趾骨血供与其生长发育有密切关系。

阴虚动风证帕金森病LID大鼠氨基酸变化的动态研究及复方地黄方的干预作用

目的探讨阴虚动风证帕金森病LID大鼠脑内氨基酸类神经递质的动态变化及复方地黄方的干预作用。方法采用6-羟基多巴胺(6-OHDA)偏侧损毁黑质制备帕金森病(PD)大鼠模型,成功的PD模型大鼠腹腔注射左旋多巴/苄丝阱[50/12.5(mg.kg)],制备阴虚动风证帕金森病LID病证的大鼠模型。将大鼠分为复方地黄方组、LID组、正常对照组、假手术组,并在治疗4周、6周后取纹状体,应用高效液相法(HPLC)测定各组大鼠纹状体内氨基酸的含量。结果阴虚动风证帕金森病LID模型大鼠纹状体内兴奋性氨基酸显著升高;复方地黄方能显著降低兴奋性氨基酸的含量,抑制性氨基酸含量则明显升高。结论复方地黄方缓解帕金森病LID的机制可能是通过调节脑内氨基酸的水平、减轻其兴奋毒性来实现的。
