温阳健心灵口服液治疗充血性心力衰竭的临床与实验研究

以煎剂形成筛选治疗CHF的处方，发现温阳益气方改善泵血功能的效果优于单纯益气和养阴益气的处方。根据前方制备的温阳健心灵口服液保持了原煎剂的疗效，并被毒理学试验证明毒性极低。动物药效学及临床试验发现该药不仅能改善心衰犬和病人的左室收缩功能，还能改善其舒张功能。除此，它还具有利尿作用和使PAWA、SVR和PVR下降的作用，这也是它抗心衰的机理之一。90例的临床观察（疗程2周）表明该药总有效率、近期治愈率和显效率分别达88．9％、7．4％和18．5％，其效与开搏通组无明显差异。     

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。     

一例~(192)Ir极不均匀外照射局部极重度放射损伤的临床观察

目的对１例１９２Ｉｒ极不均匀外照射局部极重度放射损伤病人进行临床观察。方法系统观察了病变的临床过程和应用红外线热成像技术测定了损伤部位的温度变化。结果照射后２小时出现肢体麻木、抽搐，最早照后４小时出现红斑、肿胀，５４小时出现水疱，第５天出现坏死和剧痛，最晚出现红斑、肿胀是照射后４１天，４７天出现水疱和糜烂创面。红外线热成像显示：损伤早期温度升高，水疱、坏死区和损伤后期温度降低，温度升高越早，损伤越重，温度改变区域与损伤范围相一致。结论大剂量极不均匀外照射放射损伤的初期反应早，放射病与局部损伤相互加重病情，症状先后不一，轻重不等，致残率高和疼痛剧烈，红外线热成像温度变化可以作为临床诊断的指标之一。     

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%.     

Oral manifestation of chronic mucocutaneous candidiasis: seven case reports

BACKGROUND: Chronic mucocutaneous candidiasis (CMC) is a rare disorder characterized by persistent or recurrent candidal infections of the skin, nails and mucous membranes or by a variable combination of endocrine failure as well as immunodeficiency. Oral clinicopathological features of CMC have seldom been described in detail. METHODS: Seven patients with CMC were reported in the study. The clinical and histological findings, etiological Candida species, immunological evaluation, and therapeutic pattern of oral lesions, were analyzed. RESULTS: Long-standing whitish hyperplastic and nodule-like lesions with exaggerated deep fissure were the typical and characteristic oral manifestations presented by all patients. The tongue was the most common site affected. Histologically, no obvious distinction was found between CMC and other forms of candidal infection. Abnormal proportions of T-lymphocyte subsets and positive titers of autoantibody were observed in three subjects (42.9%) and one patient (14.3%) respectively. Meanwhile, four subjects (57.1%) showed decreased albumin and increased globulin, three cases (42.9%) had high levels of ESR. But no iron deficiency was found. Candida albicans was the microorganism isolated from these patients. CONCLUSIONS: Multiple and widespread candidal infectious lesions can be observed on the oral cavity of CMC patients. Hyperplastic and nodule-like lesion with irremovable whitish patches and deep fissure are the most common oral manifestations of these patients. Dentists, otolaryngologists and pediatricians should be familiar with the clinical appearances of CMC to make an accurate diagnosis. Potential systemic disorders should be concerned to avoid the reoccurrence of oral candidiasis.     

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.
