人体经络静电荷检测研究

在经络静电荷检测基础上，研制了高灵敏微型电荷传感器系统。在１１２名正常自愿者的十二经脉五腧合穴和啼阳明胃经静电荷检测，发现正常状态下经络呈负电性（－７．８７×１０＾－３－－．６１×１０＾－１３Ｃ），经脉失衡度〈９．０６％；而在病理状态下（胃疾患）４５４例，经脉负电性小于正常人，失衡度在足三里穴达２４．０９％，稳定性差。又以胃电图离度（ＣＶ）分析，正常人空腹时，ＣＶ〈２０－３０％。胃疾患者ＣＶ〉３０

Influences of context on early writing development

Research on children's early writing development in the past has focused primarily on product and process. In reviewing the more recent research on early writing development, however, a new focus of context emerges. Occurrences of literacy are now being observed in the home, the school, and the community. With this new emphasis, comes the task of defining context. A definition of context reflects theoretical perspectives, areas of research interests, and types of methodologies employed in conducting research. Therefore, the purpose of this article is to address the following aspects of context: #op1#cp multidiscipline perspectives and definitions of context, #op2#cp contextual shifts observed between the home and the school, #op3#cp contextual factors present when learning how to write, and #op4#cp pedagogical implications for curriculum development.     

Ex Vivo Evaluation in Normal Dogs of Insulin Released by a Bioartificial Pancreas Containing Isolated Rat Islets of Langerhans

In bioartificial pancreatic systems, isolated islets of Langerhans are protected against immune rejection by an artificial membrane, permeable to glucose and insulin, but not to immunoglobulins and lymphocytes. Some of these devices, referred to as vascular systems, are set up to be connected to a vascular site in the recipient, with blood circulating in contact with one side of the membrane, and the islets on the other side. Such a bioartificial pancreas, containing isolated rat islets of Langerhans, was connected to an arteriovenous shunt of a normal anesthetized dog. The aim of this experiment was to investigate the kinetics of the insulin secretory response of the system to a glucose load. Glucose was infused upstream of the system, increasing the glucose concentration inside the bioartificial pancreas from 7 to 14 mmol/l, without altering the blood glucose concentration of the dog. Insulin concentration was determined simultaneously upstream and downstream of the bioartificial pancreas. Insulin production was calculated by multiplying the difference between these values by the blood flow rate. Blood flow rate (Q) was estimated from the change in the glucose concentration produced by the glucose infusion using a mass transfer analysis derived from Fick's principle. Insulin production increased from 20 +/- 8 to 59 +/- 15 microU/100 islets/min within 15 min following the beginning of the stimulation (n = 6, p less than 0.05). Five min after the end of the stimulation, insulin production decreased from 75 +/- 13 to 50 +/- 9 microU/100 islets/min (p less than 0.05) to reach the basal level (21 +/- 3 microU/100 islets/min) 30 min after the end of the glucose stimulation.(ABSTRACT TRUNCATED AT 250 WORDS)     

黄曲霉毒素B_1及其代谢物与原发性肝癌关系的流行病学调查

本文应用酶联免疫测定法对广西壮族自治区原发性肝癌高发的扶绥县和低发的阳朔县,进行了黄曲霉毒素B_1及代谢物黄曲霉毒素M_1和原发性肝癌关系的流行病调查。结果发现,原发性肝癌的死亡率与黄曲霉毒素B_1摄入量,晨尿黄曲霉毒素M_1排出量呈明显的正相关。展尿黄曲霉毒素M_1排出量可作为人群接触黄曲霉毒素B_1水平的指标。原发性肝癌死亡率与玉米、花生和花生油的摄入量有关。

张力带固定与钢丝环扎治疗髌骨骨折疗效分析

使用张力带固定、钢丝环扎与丝线环扎治疗髌骨骨折共６５例，平均优良率９１．５２％，但优级疗效者张力带组是８０％，钢丝及丝线环扎组分别是５６％及５６．５％。张力带内固定术后不需石膏外固定，利于膝关节早期功能锻炼与康复，疗效明显优于其它两种疗效（ｐ＜０．０５），但术中操作要求准确细致。与钢丝环扎相比，丝线环扎荷包缝合具有可避免取出内固定的第二次手术的优点，两组疗效相似。     

197例腰椎间盘膨出和脱出的CT分型

根据１９７例腰椎间盘病变的ＣＴ影像以及手术所见，提出腰椎间盘膨出分为均匀型、不均匀型、局限型；腰椎间盘脱出分为中央型、旁侧型、孔外型、Ｓｃｈｍｏｒｌ结节型。除Ｓｃｈｍｏｒｌ结节型外，上述椎间盘脱出可继续分为隆起型、破裂型、游离型等三个亚型。还讨论了分型的必要性、病理基础与临床关系以及鉴别诊断。
