近十年高血压病中医研究概况

为了促进中医药治疗高血压病的进一步发展,深入进行高血压病中医的病因病机、治法方药、作用机制的相关研究,本文对近十年有代表性的文献进行归纳分析。     

随机系统的最小熵控制

本文放弃传统的MSE准则,从信息论观点出发,发展了随机系统的一种最小熵(ME)控制方法,并从ME控制的等价性、控制限度、存在性、唯一性及必要条件等方面,研究了ME控制的合理性和实用性。ME方法是一种全局分析法,它不仅包含了MSE和MAP准则,且由于全文在整个推导中并未假定高斯性、线性和非时变等,因而原则上适用于诸如非高斯、非线性、时变等传统方法难以处理的复杂系统;不仅适用于工程系统,将其推广到决策、社会、经济等领域会更为自然和切合实际。     

Development and optimization of an indirect enzyme-linked immunosorbent assay for the determination of Hexoestrol

An indirect enzyme-linked immunosorbent assay (ELISA) for the detection of hexoestrol (HES) was developed, optimized and validated for the analysis of HES in pork. Many parameters, such as the volume ratio of solution A and solution B, colour developing time, pH value, incubation time, the volume ratio of the standard solution and diluted antiserum, blocking solution, blocking condition, coating solution and coating condition were studied and optimized in the paper. The regression equation of the final inhibition curve is y = - 0.3345x + 1.4955, R²=0.9913. The linear range is 0.1-8.1 ng/ml, and the IC₅₀ is 0.671 ng/ml. The specificity of the assay was evaluated by the cross-reactivity rates of six compounds, of which two structurally related compounds had a relatively higher cross-reactivity rate of 25% and 6%. HES was added into a pork sample at 5 ng/g level and then the sample was extracted. The recovery is between 49.6% and 79.2%, and the variation coefficient is 0.164.     

颌骨造釉细胞瘤64例临床分析

本文对我院１９５４－１９９０年收治的６４例颌骨造釉细胞瘤进行了回顾性分析，未发现１例恶性。特别是我们在长期工作实践中发现肿瘤与周围正常骨质有较明显的分界。遂于１９６３年开始试行颌骨内种瘤出术，至１９９０年６月已经成功地施了１２例，１例因手术时肿物巨大而且合并感染于术后１０年复发外，其余１１例术后随访年６个月－２７年，中位１２年１０个月均无复发。发种手术损伤小，方法简单，无损美容，预后性，特别是对颌     

抗淋球菌IgA蛋白酶单克隆抗体特性的初步研究

本文对以重组淋球菌ＩｇＡ蛋白酶为抗原制备的７株特异性ＭｃＡｂ的特性进行了初步研究。结果有５株（１Ｃ８、１Ｅ５、１Ｆ１１、１Ｇ３和２Ｅ６）能中和淋球菌ＩｇＡ蛋白酶活性。经相加试验初步证明，其中１Ｆ１１、２Ｇ３与其它３株ＭｃＡｂ的作用位点不同。因此，淋球菌ＩｇＡ蛋白酶至少存在３个中和表位。     

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.
