Methods Blood spot filter paper samples with related epidemiological data were collected from vivax malaria patients living in malarious area of 10 provinces in China. Semi nested or nested allelic specific PCR genotyping method was used to identify CSP genotypes, families and types of Plasmodium vivax of each isolate from these patients.

用滤纸血滴法采集我国 10个省间日疟现症病人血样，用套式、半套式等位特异PCR基因分型法鉴定其型、族归属及其CSP基因型，并作流行病学统计分析。

Methods Collectine the information of204patients with melasma seen in four hospitals in Tianjin to do a retrospective study.

4家医院对2003年到门诊就诊的黄褐斑患者进行回顾性流行病学研究。

The experiment on electromagnetism pulse biology effect could suggest that quantities-effect of EMP effect on system morphemic and function with applying different frequency, power and expose time. Combined with epidemic investigation and medical psychological research in EMP researcher, the immediate, early stage and middle and long-term biological effect of EMP was elucidated and EMP protection standard was established.

电磁脉冲(electromagnetism pulse，EMP)生物学效应实验是通过应用不同频率、功率、暴露时间的EMP照射动物，明确EMP所致各系统形态和功能危害的量效关系，探索其效应机理；并结合对EMP从业人员的流行病学调查和医学心理学研究，揭示EMP所引起的即刻、早期、中期和远期生物学效应，提出EMP卫生防护标准，为物理防护和医学防护的研究提供重要的理论依据和实验依据。

In the article, we took part sample out of 158 patients to exam the expression level of Bcl-2 and Fas in myasthenic thymus tissue, and to find the role of which in whole pathogenesis. we also try to find the role of neopterin and sIL-2R through examing the concentration of neopterin and sIL-2R in peripheral blood of 26 MG patients. Material and methods1.select of case: to choose 158 patients who wear followed up from 1988 to 2002 after operation. All patients were diagnosed as MG, and treated with same medical cure during period of preoperation and post operation. 2.Collectionofdata:.To collect all data through designing a uniform follow-up table for thymectomized patients ,and to analysis the effect of factors including age, gender, disease duration of preoperation, clinic types and pathological types to prognosis at three follow-up period?

本文拟在对全组病例的远期预后进行流行病学统计分析的基础上，通过抽取一定量样本，研究重症肌无力患者胸腺组织中伽 12、Fas的异常表达及生发中心的形成在重症肌无力发病机制中可能的作用，以及它们对胸腺切除术后远期预后的影响；与之相似，通过检测部分样本外周血清中新碟吟和可溶性IL－2受体的浓度及其与正常对照组的差异，以期推测两者在重症肌无力起病及病情进展中的作用和意义，并分析其对胸腺切除术后远期预后的影响。

OBJECTIVE ①To compare the sequences of the ribosomal rDNA-ITS2, 28S-D3 and mitochondrial mtDNA-COII in the different origins of Anopheles minimus for detecting the intra-and inter-specific variation of the sibling species of the Minimus Complex;②To reconstruct phylogenetic trees of the Minimus Complex and Myzomyia Series for determining the position of An. minimus A and C;③To establish specific methods for differentiation of two sibling species, An. minimus A and An. minimus C, of the Minimus Complex.

Rabies virus, the etiologic agent of fatal neurological disease, is composed of five stuctural proteins, both of the glycoprotein and the nucleoprotein are believed the decisive factors for rabies diagnosis and classification and for rabies neurotropic, pathogenicity and antigenecity.

狂犬病毒由五种结构蛋白组成，其中NP对狂犬病的诊断和分类；GP对狂犬病毒的组织嗜性、致病和免疫保护都起着决定性的作用，并且分离自不同宿主或不同地理位置的狂犬病毒之间存在着NP和GP抗原性差异，研究这种差异并结合流行病学资料有助于发现流行来源的线索。

Our aims were to identify the key factors that influenced nonadherence behavior to define effective educational strategies.A qualitative study was performed through an analysis of patient/tutor questions in interviews.

我们进行了一项定性研究，通过患者/监护人面对面问答的形式对结果进行分析；对流行病学变量、移植术后时间和反应的百分比/频率进行定量分析。
