微小病变型肾病综合征患者IL－2的检测及其意义

３２例微小病变型肾病综合征（ＭＣＮＳ）患者，采用￣３Ｈ－ＴｄＲ掺入法测定其外周血Ｔ淋巴细胞产生白介素２（ＩＬ＿２）的浓度，结果显示本病患者Ｔ细胞产生ＩＬ＿２的能力显著降低，与对照组相比差异非常显著（Ｐ＜０．０１），故认为ＭＣＮＳ的发生与Ｔ细胞功能异常有关。     

Alcohol Use among Subcritically Injured Emergency Department Patients

Objectives: To determine the incidence of alcohol use in subcritically injured patients presenting to the ED, by using a saliva alcohol test (SAT) at ED triage during the ED initial assessment; to compare the incidence of alcohol use revealed by the SAT with documentation of alcohol use by ED nurses and emergency physicians (EPs) blinded to the SAT results; and to describe the demographics of the SAT-positive, subcritically injured population.
Methods: A blinded, prospective, observational evaluation of ED patients presenting with subcritical injuries was performed. The patients were tested for alcohol use with an SAT, and a subsequent record review was conducted for extraction of demographic data and evidence of documentation of alcohol use by ED nurses and EPs blinded to the SAT results.
Results: During the study. 791 subcritically injured patients had SATs performed. Twenty-one percent of these patients were found to be alcohol-positive by SAT. Either the ED nurse or the EP documented a clinical impression of alcohol use for 52% of the SAT-positive patients. There were higher SAT-positive rates among men (24%), victims of assault (47%), and patients arriving at night (41%).
Conclusions: While the SAT identified 21% of the subcritically injured patient population as alcohol-positive, ED nurse and EP documentation did not identify half of these alcohol-positive patients. Many of these patients may be at risk for additional injuries related to their drinking behavior.     

动物肠道溶瘤病毒实验治疗荷瘤小鼠的非瘤器官光镜及电镜观察

用动物肠道溶瘤病毒(Ecco-18)实验治疗荷瘤小鼠(P_(615))时,对其非瘤器官进行了光镜和电镜观察。结果发现,荷瘤小鼠各脏器均未查到病毒颗粒或病毒性物质。各脏器的超微结构与对照组相比未见病理改变。     

Kimura's disease associated with minimal change nephrotic syndrome: A case report

Kimura's disease is a rare disorder that involves regional lymph nodes and the major salivary glands, which become infiltrated by eosinophils and lymphocytes. Renal lesions associated with Kimura's disease are rare. We describe the case of a 60-year-old Japanese woman who first noted a nodular mass in a salivary gland. As the nodule grew, nephrotic syndrome and heart failure developed. A biopsy of the nodule revealed Kimura's disease, and surgical excision was performed. After the operation, the heart failure and nephrotic syndrome, which were diagnosed as minimal change disease on renal biopsy, improved rapidly without steroid therapy. Four months later, the nephrotic syndrome recurred without recurrence of Kimura's disease. The patient showed marked improvement during prednisolone therapy (40 mg/d) and was in complete remission 4 weeks after the initiation of steroid therapy. This case shows that surgical excision and prednisolone therapy are useful for nephrotic syndrome associated with Kimura's disease.     

复方桂枝汤中芍药甙煎出量的动态分析

 本实验运用CS－930双波长薄层色谱扫描仪，分析测定桂枝汤方剂在煎煮过程中，其主药芍药的主要化学成分芍药甙量的动态变化。结果表明，煎煮时间在30min时，芍药甙煎出量较高。该法简便、快速，色谱分离良好，排除了其它成分的干扰。平行性和重现性较好。     

圆形分布法在蝇类季节消长规律中的应用

目的确定蝇类季节消长的高峰日和高峰时段,为制定蝇类防制措施提供科学依据。方法用圆形分布法统计分析绍兴市区2003-2004年蝇类密度监测数据。结果绍兴市区2003-2004年蝇类平均密度高峰日为8月4日,高峰时段为6月8日至9月30日。其中2003年蝇类密度高峰日为8月11日,高峰时段为6月17日至10月5日;2004年蝇类密度高峰日为7月29日,高峰时段为6月1日至9月26日。结论绍兴市区2年中蝇类消长有明显的季节性规律。     

胃粘膜癌变初发点及其组织背景的病理学：癌变初发点的一般组织病理学

本文通过对228例各种类型胃粘膜上皮异型增生的病理切片的复查,发现并详细地描述了不同类型异型增生腺管和上皮细胞癌变的初发点(Start point)。其形态有的是从再生腺管的腺颈部或底部以“发芽”形式,向质内浸润并分枝生长;有的是从再生腺管基底膜向侧方的间质浸润。从再生的胃上皮型异型腺管所出现的癌变多为低分化型腺癌;从肠上皮型异型腺管所发生的癌变则为高分化型腺癌。强调了胃粘膜再生性异型增生有些具有癌前性质。     

彩色多普勒超声诊断糖尿病下肢动脉病变的临床价值

目的 :研究彩色多普勒超声在糖尿病下肢动脉病变诊断中的应用。方法 :对临床上诊断为非胰岛素依赖型糖尿病 (NIDDM)患者发生下肢动脉病变的 6 2例进行彩色多普勒超声检查 ,并以 2 0例无糖尿病正常人作对照。结果 :6 2例NIDDM患者中阳性结果 4 0例 ,发病率 6 4 .5 2 %。正常对照组 2 0例 ,阳性结果 4例 ,发病率2 0 % ,下肢动脉病变程度与NIDDM组有显著性差异P <0 .0 1。结论 :彩色多普勒超声诊断糖尿病下肢动脉病变具有重要临床意义 ,且下肢动脉病变与NIDDM有密切相关性。     

皮肤交界性平滑肌瘤的复发与恶性转化

目的探讨皮肤交界性平滑肌瘤的复发与恶性转化。方法复习2例皮肤交界性平滑肌瘤及其复发恶性转化的临床病理特征、免疫组化表型及相关文献。结果2例病变位于下肢和额部，肉瘤组织平滑肌标记阳性。结论少数病理诊断为皮肤平滑肌瘤的病例，虽然浅表且组织形态良性，但其生物学恶性潜能尚不能确定，部分病例复发后可转变为典型的平滑肌肉瘤。
