乙型脑炎、麻疹胎传母体抗体的调查

86对母婴血清标本用间接酶联免疫测定法(ELISA)测定了乙型脑炎抗体,118对用血凝抑制(血抑)试验测定了麻疹抗体。结果发现,脐血乙型脑炎抗体阳性率为79.1％,母血为74.4％,几何平均滴度在脐血显著高于母血(t=5.1857,P<0.01),比值为1.2∶1。脐血和母血的麻疹血抑抗体阳性率分别为86.4％及84.8％,几何均值也是前者高于后者(t=4.0349,P<0.01),比值为1.3∶1。 108份婴儿血清标本测定结果显示,0～3个月婴儿乙型脑炎抗体阳性率为35％,4～9个月仅为13％,10个月及以上的婴儿全部阴性。此结果与近年上海市小于1岁组乙型脑炎发病率最高相一致,提示应考虑提早乙型脑炎疫苗的接种年龄。     

猕猴桃汁抗环磷酰胺致突变作用的机理

目的用大鼠外周血双核淋巴细胞微核测试法（ＣＢＭＮＴ），在哺乳动物整体水平，研究猕猴桃汁抗环磷酰胺（ＣＰ）的致突变作用以及生物转化Ⅱ相酶的作用。方法测定大鼠外周血双核淋巴细胞微核细胞率及肝组织中总谷胱甘肽硫转移酶（ＧＳＴ）、尿苷二磷酸葡萄糖醛酸转移酶（ＵＤＰＧＴ）、谷氨酰胺转肽酶（γＧＴ）活性。结果猕猴桃汁对ＣＰ诱发的大鼠外周血双核淋巴细胞微核细胞率有显著抑制作用，能明显诱导大鼠肝脏总ＧＳＴ、ＵＤＧＴＰ活性，但对γＧＴ活性无显著影响。大鼠外周血双核淋巴细胞微核细胞率与总ＧＳＴ、ＵＤＧＴＰ活性呈明显负相关。结论猕猴桃汁抗ＣＰ致微核形成作用的机理可能是通过诱导机体外来化合物代谢解毒酶系，加速ＣＰ的代谢灭活     

B超引导下经皮穿刺囊内注射铝溶液治疗肾囊肿

在 B 超引导下经皮穿刺囊内注射铝溶液治疗肾囊肿72例89个囊肿结果:消失48个,有效36个,总有效率94%。随访3个月至2年未见复发。其方法安全、简便、无副作用。并对铝溶液作用机制进行初步探讨。     

子宫脱垂的原因及预防

子宫从正常位置沿阴道下降，子宫颈外口达坐骨棘水平以下，甚至子宫全部脱出阴道口外，称为子宫脱垂。     

111例双黄连过敏反应文献分析

目的:分析临床应用双黄连引致的过敏反应的规律。方法:对2000年1月-2004年3月中国期刊网中收录的111例双黄连过敏反应在性别、年龄、发生时间、给药途径和临床表现进行分析。结果:双黄连过敏与年龄、性别无关,与给药途径有关,注射剂易发生过敏反应。该药过敏的临床表现有:过敏性休克67例(60%),皮肤黏膜症状61例(55%),其他类型过敏反应14例(13%)31例同时出现多种过敏症状。过敏发生时间最短为开始用药1m in以内,最长为用药后72h,97例(87%)在用药过程中发生过敏症状。结论:双黄连的过敏反应以速发型过敏反应(如过敏性休克)为主,应是临床关注的重点。     

HBsAg母婴传播的研究

对HBsAg(+)母亲所生婴幼儿,连续两年的动态观察,发现这些婴幼儿的感染绝大多数皆在出生3个月后,其感染频率与母亲HBsAg的滴度成正相关,表明母婴传播阻断应以HBsAg(+)母亲所生之子女为重点对象。     

Clinical and hormonal effects of chronic gonadotropin-releasing hormone agonist treatment in polycystic ovarian disease

Previously, we reported that short term administration of a highly potent GnRH agonist (GnRHa) for 1 month to patients with polycystic ovarian disease (PCO) resulted in complete suppression of ovarian steroidogenesis without measurable effects on adrenal steroid production. This new study was designed to evaluate the effects of long term GnRHa administration in PCO patients with respect to their hormone secretion patterns and clinical responses. Eight PCO patients and 10 ovulatory women with endometriosis were treated daily with sc injections of [D-His6-(imBzl]),Pro9-NEt]GnRH (GnRHa; 100 micrograms) for 6 months. Their results were compared to hormone values in 8 women who had undergone bilateral oophorectomies. In response to GnRHa, PCO and ovulatory women had rises of serum LH at 1 month, after which it gradually declined to baseline. In both groups FSH secretion was suppressed throughout treatment. Serum estradiol, estrone, progesterone, 17-hydroxyprogesterone, androstenedione, and testosterone levels markedly decreased to values found in oophorectomized women by 1 month and remained low thereafter. In contrast, serum pregnenolone and 17-hydroxypregnenolone were partially suppressed, and dehydroepiandrosterone, dehydroepiandrosterone sulfate, and cortisol levels did not change. Clinically, hyperplastic endometrial histology in three PCO patients reverted to an inactive pattern, and proliferative endometrium in two other PCO patients became inactive in one and did not change in the other. Regression of proliferative endometrial histology occurred in all ovulatory women. Vaginal bleeding occurred in all women studied during the first month of GnRHa administration, after which all but one PCO patient became amenorrheic. Hot flashes were noted by all ovulatory women and by four of eight PCO patients. All PCO patients noted subjective reduction of skin oiliness, and five had decreased hair growth. We conclude that in premenopausal women: 1) chronic GnRHa administration results in apparently complete persistent suppression of ovarian steroid secretion; 2) adrenal steroid secretion is not influenced directly or indirectly; and 3) its use may be helpful in the treatment of endometrial hyperplasia and ovarian androgen excess in women with PCO.     

异搏定防治流行性出血热初期急性肾功能衰竭的疗效观察

在综合疗法的基础上加用异搏定3～5天治疗流行性出血热(EHF)发热后期病人41例,在尿蛋白转阴、越期率,特别是越少尿期平明显优于对照组,但对 BUN 水平的影响与对照组无异,异搏定对防治 EHF 急性肾衰具有一定疗效。
