甲状腺疾病患者血清TSAb和TBII的检测

采用细胞培养生物学方法和放射受体分析法检测甲状腺疾病患者血清甲状腺刺激抗体（ＴＳＡｂ）和促甲状腺激素结合抑制免疫球蛋白（ＴＢＩＩ）。发现Ｇｒａｖｅｓ病未治组ＴＳＡｂ和ＴＢＩＩ活性与阳性率明显高于Ｇｒａｖｅｓ病缓解组和桥本甲状腺炎（ＨＴ）组，后两组ＴｓＡｂ和ＴＢＩＩ活性与阳性率高于甲状腺腺瘤组和正常对照组。Ｇｒａｖｅｓ病未治组、缓解组和ＨＴ组其ＴＳＡｂ和ＴＢＩＩ的检出率分别为９１．７％和７９．２％、４８．０％和４４．０％及２３．１％和６１．５％。甲状腺腺瘤组和对照组ＴＳＡｂ和ＴＢＩＩ均为阴性，其活性亦无统计学差异。血清ＴＳＡｂ与ＴＢＩＩ活性以及ＴＳＡｂ、ＴＢＩＩ活性与Ｔ＿３、Ｔ＿４、ＦＴ＿３和ＦＴ＿４浓度之间均无显著相关性。提示ＴＳＨ受体抗体具有异质性，联合检测这两种抗体对了解自身免疫性甲状腺疾病（ＡＩＴＤ）的发病机理，合理诊治甲状腺疾病具有重要的临床价值。     

Prevention of perinatal transmission of hepatitis B virus (HBV): a comparison of two prophylactic schedules

Perinatal transmission of hepatitis B virus (HBV) from HBsAg carrier mothers who were HBeAg+, antiHBe+, or negative for both HBe markers, was interrupted using either 4 doses of vaccine, or one dose of hepatitis B immunoglobulin (HBIG) at birth, combined with 4 doses of vaccine. In those infants who received HBIG at birth, the antiHBs titre was significantly higher at 1 and 2 months old, but at 6, 9, and 18 months old, there was no significant difference. Among the infants of carrier mothers who did not display HBeAg (i.e., were antiHBe+, or negative for both HBe markers), a transient subclinical infection would have been expected in around 10% had there been no intervention. No evidence of such infection was detected, and no difference in outcome was found between the two treatment groups. Amongst infants born to HBeAg+ carrier mothers, infection occurred in 1 out of 8 who had received HBIG and vaccine, and in 3 of 8 who had received vaccine only. The difference in outcome was not statistically significant, but the numbers analysed were small. The infections which occurred in spite of prophylaxis may be attributable to in utero infection, poor response to vaccine by the infant, or to the mother having a particularly high HBV-DNA level. HBIG given at birth to infants of HBeAg+ carrier mothers may enhance the protection of infants who are destined to be poor responders to vaccine.     

两种方法诊断贵阳市某城区20～45岁人群代谢综合征的一致性

目的：了解贵阳市某城区20至45岁成人代谢综合征（Ms）的患病情况,并对2005年国际糖尿病联盟（IDF）标准和全球共识（JIS）标准的诊断结果的进行比较。方法：采用分层整群抽样方法对贵阳市某城区20岁～45岁常住居民共796人（男341人,女455人）进行问卷调查、体格检查及相关代谢指标的测定,采用IDF和JIS标准判断不同性别青年人MS及其各组分的患病率,观察两种标准诊断不同性别青年人MS患病情况的一致性。结果：该年龄段人群用IDF标准诊断Ms的粗患病率为22．2％（男性24．0％,女性19．3％）,男女无差异（r=2．57,P〉0．05）,用JIs标准诊断Ms的粗患病率为31．3％（男性41．6％,女性23．5％）,男性高于女性（,=29．791,P〈0．05）;IDF诊断中心性肥胖为30．5％,JIS诊断中心性肥胖为38．4％;JIS诊断甘油三酯升高、高密度脂蛋白胆固醇降低、血压升高及空腹血糖升高的粗患病率分别为31．3％、55．0％、18．3％、46．4％,二种标准对女性代谢综合征的诊断一致性较好（K=0．876）,对总体人群和男性一致性一般（K值分别为0．615和0．747）。结论：IDF和JIS诊断标准均显示该城区青年MS的患病率较高,两种方法对女性MS诊断的一致性较好。     

口腔溃疡煎对复发性口疮患者免疫功能影响的临床研究

从提高患者机体免疫功能着手,自拟口腔溃疡煎对40例复发性口疮患者进行了疗效观察,并对治疗前后进行了T细胞亚群及血清免疫球蛋白、补体C3的检测。结果显示:(1)复发性口疮患者的CD4+和CD8+细胞的平衡失调,IgG和IgA及补体C3的含量下降,说明细胞免疫功能和体液免疫功能低下;(2)通过口腔溃疡煎的治疗,患者的临床症状明显改善,有效率为92.5％,并可以调节CD4+细胞和CD8+细胞的平衡,提高体内IgG和IgA及补体C3的含量。由此推测本方剂有调节机体免疫功能的作用。

Rabbit-mouse hybridomas secreting intact rabbit immunoglobulin

Rabbit-mouse hybridomas offer the potential for production of monoclonal rabbit antibodies by immortal cell lines. In previous studies, it was possible to produce and stabilize rabbit-mouse hybrid cells secreting either a rabbit heavy or light chain. These have been useful for structural characterization of the individual rabbit immunoglobulin polypeptides and for isolation of large amounts of immunoglobulin mRNA for molecular studies. For some studies, however, it would be useful to have intact rabbit immunoglobulin molecules comparable to the myeloma proteins available in the human and mouse. The availability of rapid, sensitive and specific assays for rabbit heavy and light chains and allotypes located on specific chains has now permitted the early identification of clones secreting intact rabbit immunoglobulin. Vigorous cloning efforts have resulted in isolation and partial stabilization of three such clones. The first, H105, secretes a product with a kappa light chain bearing the b6 allotype and a mu-chain bearing the a1 allotype. Biochemical and serologic analyses of the product show that it is secreted as a fully assembled IgM pentamer and that the rabbit heavy and light chains are covalently associated. No rabbit J-chain gene was detected in H105 by Southern blot analysis. The second hydridoma, H134, secretes a product with a mol. wt of 150 K, consisting of a b4 light chain and an a1 heavy chain. The third, H171, secretes an alb4 IgG with antibody specificity for group C streptococcal carbohydrate. An additional rabbit-mouse hybridoma, H89, have been produced which secretes a rabbit heavy chain lacking group a allotypic activity. The rabbit heavy chain, which is associated with a mouse light chain, has an N-terminal amino acid sequence identical to a2-positive molecules although thorough serologic analysis revealed no group a allotypic activity.
