我国食管癌发病危险因素的Meta分析

目的：评价我国食管癌发病的危险因素。方法：通过Meta分析对国内13篇公开发表的有关食管癌发病危险因素的病例-对照研究进行定量综合分析，共对12个因素进行评价，计算每个因素的综合OR值．结果：共有9个因素有显意义，分别为：吸烟(ORs=1．69)、饮酒(ORs=1．81)、酸菜(0Rs=2．22)、烫食(ORs=2．41)、家族史(ORs=4．00)、精神因素(ORs=3．06)、干硬食物(ORs=2．07)、吃饭快(ORs=1．82)、水果(ORs=0．39)．结论：吸烟、饮酒、酸菜、烫食、家族史、精神因素、干硬食物及吃饭快为食管癌发病的危险因素，水果为保护因素，而蔬菜、饮茶以及肉类对食管癌发病的作用尚不能确定。

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。     

巩膜环扎加压术后眼轴与屈光状态的改变

目的：探讨视网膜脱离巩膜环扎加压术后眼部屈光状态的改变。方法：用眼科A超、检影验光等对86例原发性视网膜脱离患者的86只患眼手术前1d及术后1、4、12w时的眼轴长度、眼屈光度等进行测量并将结果进行比较。结果：眼轴长度在术后1、4、12w时均较术前增长(P＜0．01)。眼屈光度在术后1、4、12w时均较术前增加，且向负值偏移(术后1、4w，P＜0．015术后12w，P＜0．05)。结论：巩膜环扎加压术后眼轴长度和屈光状态的变化与眼内嵴有关，术后眼轴增长是眼屈光度负值增加的主要因素。     

有机结合 共同发展——从血清脂蛋白谱研究谈中西医结合体会

在整体观和平衡观的基础上 ,创立双梯度聚丙烯酰胺凝胶电泳法 ,应用于同步分离血清脂蛋白及其亚组分 ,检测血清脂蛋白谱 (SLPG) ,以及“内脾虚”的基础和临床研究 ,并逐步建立了新的理论体系。SLPG较理想地表达了血清脂蛋白动态平衡的状态 ,是中西医结合认识血脂代谢和“脾气散精”功能的新指标。实践提示 ,有机结合和共同发展应是现代中西医结合研究面临的主要任务之一。     

Age-Dependent Prevalence of Cardioembolic Sources Detected by TEE: Diagnostic and Therapeutic Implications

To define the prevalence of cardioembolic sources found by transesophageal echocardiography (TEE) in different age groups of patients with and without cryptogenic systemic embolism, TEE risk factors for cardiogenic embolism were identified from 341 consecutive patients referred for TEE. One hundred and thirty-five had cryptogenic cerebral or systemic peripheral embolic events (CEE) and 206 other indications for TEE (CTR). Cardioembolic sources were found in 40% of CEE and in 29% of CTR (P < 0.02). Specifically, left atrial (LA) thrombi (P < 0.0001), atrial septal aneurysm with right-to-left shunt (P < 0.002), and atherosclerotic aortic plaques (P < 0.02) were more frequent. The prevalence of potential cardioembolic sources was significantly higher in patients ≥ 70-years old than in younger patients (P < 0.03), specifically LA thrombi (P < 0.004) and atherosclerotic aortic plaques (P < 0.0001). In patients ≥ 70-years old, potential cardioembolic sources were found in 63% and in 40% in CEE and CTR (P = 0.073), respectively. However, LA thrombi were more frequent in CEE (P < 0.003). Thus, potential cardioembolic sources observed by TEE are found more frequently in patients ≥ 70-years old than in younger patients. LA thrombi were more frequent in CEE than in CTR patients ≥ 70-years old. In patients ≥ 70-years old with CEE who are eligible for an anticoagulant regimen, a search for potential cardioembolic sources by TEE should be considered.
