Methods :90 SD rats were randomly devided into control group (1 month, 2 months, 3 months) and model group (1 month, 2months, 3 months), made rat models by pouring Lipopolysacchride into trachea and putting rats into smoking environment, and anaesthetised with ether, striped the spleen and thymus, and weighted.

The wistar rats model of 2-DM were induced by high calorie feeding and small dose injection of STZ. Rats were randomly divided into diabetic model group, diabetic model treated with RGL (2.4 g·kg-1·d-1), RGL (1.2 g·kg-1·d-1), RGL (0.6 g·kg-1·d-1) and normal control group.

Wistar大鼠喂以高热量饲料加链脲佐菌素建立2型糖尿病大鼠模型，随机分为正常对照组、2型糖尿病模型组、地黄高、中、低剂量治疗组。8周后，以RT-PCR法检测大网膜脂肪组织resistin基因mRNA的表达，以SDS-PAGE检测其蛋白的表达。

Abstract］ Objective To investigate whether there is difference of blood pressure between left and right arms in order to provide the reference materials for clinical blood pressure measurement.Methods Two hundred university students were recruited in this study by randomly sampling in different layers.Using both mercury manometer and electronic manometer at the same time,the blood pressure of both arms was measured when the student was sitting by the researcher with standard measuring methods.

目的 调查学生双上肢肱动脉血压有无差异，临床血压测量提供参考资料方法采用分层随机抽样法抽得在校大学生共200人，按标准方法固定专人分别用汞柱台式血压计和臂式电子血压计测量坐位的双上肢血压。

Eligible patients were randomised blindly by the data centre of the Institut Gustave Roussy (PCI99-01 and IFCT) using minimisation, and by the data centres of EORTC and RTOG (for CALGB, ECOG, RTOG, and SWOG), both using block stratification.

选出来的患者在盲法前提下，Gustave Roussy研究所数据中心（PCI99 - 01和IFCT）使用最小化进行随机化，EORTC数据中心（EORTC ROG和LG）和RTOG (CALGB，ECOG，RTOG，和SWOG)都使用板块分层。

METHODS: A single oral dose 600 mg of 2 valaciclovir hydrochloride tablets was given to 18 healthy volunteers in an open randomized crossover study. The concentration of acyclovir in plasma was determined by HPLC at different time points within 14 h following administration. The pharmacokinetic parameters were calculated by BAPP 2.0 software and the bioequivalence was evaluated by two onesided t test and 90%confidence intervals.

采用双周期、单中心、开放、自身交叉对照的研究方法，18例健康志愿者随机分为两组，单次，交叉口服盐酸伐昔洛韦片600 mg后，以HPLC法测定血浆中阿昔洛韦的浓度，采用BAPP2.0软件进行数据处理，计算药代动力学参数。
