四叠体池蛛网膜囊肿

目的:探讨四叠体池蛛网膜囊肿的临床特征和治疗方法。方法:对11例四叠体池蛛网膜囊肿进行了回顾性总结分析。所采用的手术方法有:①脑室分流手术;②囊肿-腹腔分流术;③囊肿切除;④囊肿切除加囊肿-脑池分流术,或囊肿部分切除(即囊肿开窗术),或囊肿切除加脑室-脑池分流术。结果:其主要临床表现以颅内压增高症和中线综合征为主。上述方法中单纯囊肿壁切除只能使部分病人的病情缓解,脑室分流或囊肿切除加脑室分流手术的疗效较好。结论:四叠体区蛛网膜囊肿常合并梗阻性脑积水,单纯囊肿切除不能解除多数病人的梗阻性脑积水。作者根据囊肿是否与蛛网膜下腔相通提出:对交通性蛛网膜囊肿采用单纯性脑室分流术,对非交通性者采用囊肿切除加脑室分流手术的治疗方法。     

美沙酮联用丁丙诺啡对海洛因依赖重度药瘾戒毒治疗临床研究

目的　探索对海洛因依赖重度药瘾较理想的戒毒治疗方法。　　方法　采用美沙酮与丁丙诺啡联合用药方案 ,对海洛因依赖重度药瘾 41例行戒毒治疗 ,1 2天为一疗程 ,并与单用美沙酮组 2 0例进行比较。　　结果　联合用药组控制症状较彻底 ,鸦片类药物戒断症状量表 (OWS)总分平稳下降 ,症状波动小 ,减药顺利 ,两药替换平稳 ,戒毒成功率 73 2 %。　　结论　我们认为美沙酮联用丁丙诺啡是一种值得推荐的戒毒治疗方法。     

Rh血型不合新生儿溶血病检测方法及应用

产前检测Ｒｈ，Ｄ因子及抗人球蛋白（ｃｏｏｍｂｓ）试验是必要的。测定Ｒｈ，Ｄ因子及抗Ｄ滴度使用木瓜酶方法。通过对１１２６１例孕妇常规检查Ｒｈ，Ｄ因子，发现Ｄ阴性７４例。Ｒｈ，Ｄ阴性妇女占６．５‰。２２例Ｒｈ，Ｄ阴性的孕妇所分娩的新生儿均为Ｒｈ，Ｄ阳性。其中２例孕妇血清抗Ｄ滴度为１∶３２，病情严重，宫内输血无效，胎死宫内。初产妇１３例，占５９％。活产２０例，存活率９０％。Ｒｈ因子及抗人球蛋白试验方法简便、易行，一般医院均可进行。对有流产史、输血史的孕妇检查Ｒｈ因子是十分必要的。在有条件的医院，对Ｒｈ，Ｄ阴性的产妇分娩Ｒｈ，Ｄ阳性的新生儿之后，产妇应预防性注射抗Ｄ免疫球蛋白     

A preliminary study of the changes in the direct-acting mutagenicities of several nitropolycyclic aromatic hydrocarbons after exposure under sunlight

Five commercially available nitropolyclyclic aromatic hydrocarbons (nitro-PAH), namely, 4-nitrobiphenyl, 2-nitrofluorene, 9-nitroanthracene, 1-nitropyrene, and 2,7-dinitrofluorene, were exposed under restricted sunlight in the open air. The direct-acting mutagenicities of the samples after an exposure of 45 days were measured in order to compare them with those of the original samples in the Ames Salmonella typhimurium bioassay. It was found that the mutagenicities of some nitro-PAH do not change significantly while the mutagenicities of others increase or decrease after exposure. A preliminary study of nitro-PAH reaction products after exposure using GC, GC/MS, and FT-IR is also reported.     

Influence of Qingdai Compound Capsule on the expression of c-myc in psoriatic keratinocytes) on the expression of c-myc in psoriatic keratinocytes

In this immunohistochemical study, the authors detected the expression of c-myc in keratinocytes (ECK) from 30 psoriatics before and after Qingdai Compound Capsule (QDCC) treatment and 12 normal subjects for control. The results showed that the ECK of patients before treatment was significantly higher than that in the normal control group, and its level was correlated with histopathological changes of affected skin. After treatment the ECK was normalized. It is believed that QDCC could decrease the ECK in psoriatics and this effect was probably mediated by inhibiting c-myc expression. This study provided an experimental evidence for the application of QDCC in treating psoriasis.
