神经梅毒的临床特征与诊断分析

目的：分析神经梅毒的分型和临床特征及提供早期诊断依据。方法：回顾性分析经临床和实验室检查确诊的18例神经梅毒病人的有关临床资料。结果：神经梅毒的临床特征包括：(1)急性、亚急性起病为主；(2)临床以间质型，尤其是以脑卒中起病常见，症状元特异性；(3)血清学检查以梅毒螺旋体血凝试验(TPHA)及快速血浆反应素试验(RPR)特异性较高；(4)脑脊液检查表现为压力增高(42．9％)、蛋白增高(81．2％)及细胞数增高(56．3％)；(5)头颅CT、MRI表现与高血压、动脉硬化所致脑梗死不同，为多发、散在病灶。结论：神经梅毒早期误诊率高，临床表现与分型密切相关，实验室及影像学检查是诊断的重要依据。     

优立新治疗急性细菌性感染的临床观察

优立新与头孢噻肟随机对照治疗呼吸道和泌尿道感染４０例，临床有效率各为１００％和９５％（Ｐ＞０．０５），细菌阴转率各为９４，１％和１００％（Ｐ＞０．０５）。无显著性差异。优立新共治疗３０例，临床有效率和细菌阴转率分别为１００％和９６％。两药副反应均轻微。无因副反应而停药。在优立新治疗病例中，有２例出现皮疹。另２例为肝功能ＡＬＴ和ＡＳＴ暂时性轻度增高。     

Epidemiology and clinical manifestation of HIV infection in Northern Zaire

1275 patients were evaluated for HIV-1+2 seroprevalence and its association with clinical symptoms of HIV infection. Of 667 apparently healthy subjects, 8.2% had anti-HIV-1 antibodies. In 465 patients with clinical signs of AIDS, 39.4% were seropositive. 143 patients with miscellaneous symptoms had positive predictive values for HIV infection between 67% (vaginal ulcerations) and 20% (profound pyogenic abscesses). The WHO definition for AIDS had a specificity of 78.3%, a sensitivity of 72.2% and a predictive value of 61.6%.     

Segregation analysis of diastolic blood pressure in a large pedigree

Hypertension, a major risk factor for cardiovascular diseases, is thought to be inherited to some extent. However, the nature of its genetic component remains unresolved. In the present study, data from a single large kindred (the HGAR1 pedigree) were used to search for evidence of single gene and multifactorial effects on diastolic blood pressure. Commingling analyses found that a mixture of three distributions fit the data significantly better than a single normal distribution, suggesting a major effect influencing diastolic blood pressure levels. However, segregation analysis, using regressive models, indicated that the transmission probabilities were not consistent with Mendelian expectations. There was no evidence of either major gene or polygenic effects on diastolic blood pressure levels in this family. © 1993 Wiley-Liss, Inc.     

碰撞癌的临床影像学表现及病理分析

目的:探讨碰撞癌的临床影像学表现、发病机制与病理特点。方法:回顾性分析20例碰撞癌的临床影像学资料并结合文献复习,总结其患病率、发病年龄、性别比、好发部位、临床影像学表现、治疗手段、病理特点。结果:碰撞癌罕见,好发年龄大于58岁,男性发病多见,好发部位为食管-贲门,食管-胃底等。临床表现无特殊,术前影像学检查多不能明确诊断,术后病理诊断是唯一的确诊方法。治疗以手术为主,辅以化疗或放疗。病理特点为同一宿主同一部位或器官2个不同类型肿瘤的结合,瘤组织间没有移行和混合,有各自的转移途径,碰撞癌以鳞癌和腺癌的碰撞为主。结论:碰撞癌是一种罕见的恶性肿瘤结合,临床特点有待进一步总结,影像学综合诊断有助于提高其确诊率。     

Skilled birth attendant competence: an initial assessment in four countries, and implications for the Safe Motherhood movement.

OBJECTIVES: Percentage of deliveries assisted by a skilled birth attendant (SBA) has become a proxy indicator for reducing maternal mortality in developing countries, but there is little data on SBA competence. Our objective was to evaluate the competence of health professionals who typically attend hospital and clinic-based births in Benin, Ecuador, Jamaica, and Rwanda. Methods: We measured competence against World Health Organization's (WHO) Integrated Management of Pregnancy and Childbirth guidelines. To evaluate knowledge, we used a 49-question multiple-choice test covering seven clinical areas. To evaluate skill, we had participants perform five different procedures on anatomical models. The 166 participants came from facilities at all levels of care in their respective countries. Results: On average, providers answered 55.8% of the knowledge questions correctly and performed 48.2% of the skills steps correctly. Scores differed somewhat by country, provider type, and subtopic. Conclusion: A wide gap exists between current evidence-based standards and current levels of provider competence.     

抗癫痫药物不良反应的针灸治疗

采用针灸方法治疗1例癫痫患者,选取可直接调心脑之气的心俞穴,起化痰作用的肝俞、肾俞穴,具有平衡阴阳之气的后藤艮山灸法(取穴:大椎、长强及其中点和中点左右各4cm处共5个穴位,均为非化脓灸),另外采用本神透阳白、阳白透本神的刺法,给上额以交叉刺激。经3个月治疗患者癫痫发作及药物副作用基本得到控制,疗效满意,但其治疗机制尚须深入探讨。     

活动性结核标志物'H-多肽的实验与临床研究

本题研究是经免疫学途径直接检测人体感染结核菌的情况，为现代结核病的实验诊断、临床监测、流行病调查提供了一个全新的检验指标。作者首先发现了一种仅存在于活动性结核病患者体液中的蛋白成份—活动性结核标志物（ＡｃｔｉｖｅＴｕｂｅｒｃｕｌｏｓｉｓＭａｒｋ—ＡＴＭ）１Ｈ—多肽；并为之创立了独特的检测方法，经四年多临床１９４６０例样本调查中确定了ＡＴＭ的临床价值。将ＡＴＭ检测与ＯＴ皮试、酶联免疫ＥＬＩＳＡ、ＤＮＡ探针、ＰＣＲ基因扩增技术及典型病例组患者行Ｘ线计算机断层摄影（ＣＴ）、磁共振像（ＭＲＩ）等多组对比试验中，实验与临床研究资料分析证明：ＡＴＭ检测的总敏感度为８６．０６％、特异度９６．２４％、准确度９３．４５％、诊断效率为８２．８２％、批内ＣＶ１．２％、批间ＣＶ２．０％、Ｐ＜０．０５。经ＮＭＲ光谱分析结构含有ＣＣＨ２官能团。
