Results The values of sICAM-1,sVCAM-1 and tIgE in asthmatic patients were significantly higher than those in control (P＜0.01).There were 19 positive sIgE of artemisia pollen and 12 postive sIgE of dermatophagoides pteronyssinus in 23 patients.There was linear correlation between sICAM-1 and tIgE (R-square=0.502,standard partial regression coefficient=0.097,t=2.841,P=0.021 8) with stepwise regression analysis.

结果 血清sICAM-1、sVCAM-1、tIgE水平测定哮喘组均高于对照组(P＜0.01)；血清中以户尘螨和蒿草花粉的特异性IgE含量增高为主；经多元逐步回归分析提示血清总IgE含量与sICAM-1存在线性关系，其复相关平方为0.502，标准偏回归系数为0.097，t＝2.841，P＝

In the third part, we study an application of stereographic projection transformation in statistics, deriving Box-Muller formula (use two independent uniform random number to generate two independent standard normal random number) and spherical symmetric distribution (a product of a positive random variable and a random vector with uniform distribution) in multivariate statistical analysis.

第3章，研究了球极投影变换在统计中的应用，通过球极投影变换获得了利用两个相互独立的均匀随机数生成两个相互独立的标准正态随机数的Box-Muller公式以及多元统计分析中的球对称分布（一个正的随机变量和一个与之相互独立的均匀分布的随机向量的乘积）。

Methods CHD patients were proved by coronary arteriongraphy. 64 patients with type 2 diabetes in combination with CHD were enrolled in group A and 98 patients with simple CHD served as group B. Patients of group A were subdivided into 3 groups based on scalar of the stenotic coronary artery, viz 1 rarnus, 2 rami and 3 rami affection groups, and urinary albumin level was determined. In group A, age, course of DM, BMI, BP, BS, GHbA1c, blood-fat, UAL serving as iv, and affection sum and stenosis index serving as dv, ran polynary gradual regressive analysis.
