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＝

The mPAP correlated nagatively to RVEF (r=-0 .6097, P＜0.001). For this reason, the measurement of RVEF by radionuclide ventriculography was regarded as reliable . Through stepwise regressive analysis we got the multiple linear regressive equation as follows

本文结果显示mPAP与RVEF呈显著负相关(r＝-0.6097，P＜0.001)，说明核素技术检查COPD、肺心病人的EF值是可靠的。mPAP与RVEF、SaO〓、PAD等多项无创检查参数相关，并通过逐步回归分析得到下面的最优多元回归方程

Initiation of the 6-month treatment with bena zepril induced a signif icant drop in MABP, UAER and ACE levels in all three groups(P＜0.05), but th e reduction was significantly greater in patients with II genotype (UAER 58.6%, MABP 2.87 kPa, ACE 72.3%), compared with patients with either ID or DD geno type (P＜0.01, respectivly).

结果：苯那普利治疗后3组UAER、MABP、ACE均下降，以II型组下降幅度最大(分别为58.6%、2.87kPa和72.3%)，DD型组下降幅度最小(P＜0.05)；而Ccr在DD型组下降幅度最大，II型组下降幅度最小(P＜0.05)；多元线性逐步回归分析显示：ACE基因型对UAER下降率有显著回归效果(R2=0.72，P＜0.001)。

The harm extent of Dendrolimus tabulaeformis and D. spectabilis were analyzed by fourteen forest factors, from which four significant ones were selected: crown density, altitude, average diameter at breast height and MLP. MLP is a new parameter suggested in this paper. It is better than diversity index to the harm extent, and it can indicate some information on not only the under story plant species diversity but the forest environment. Using the four key factors a multiphase linear regression model was made for risk analysis of the harm extent of pine caterpillar.

该文首次提出了林下植物喜湿度参数MLP(Moisture-Loving Parameter)，并用包括MLP在内的14个林分因子与松毛虫危害程度进行逐步回归分析，从中筛选出主林层郁闭度、海拔高度、油松平均胸径和林下植物喜湿度参数4个关键因子，与松毛虫危害程度之间均呈显著的负相关关系，并进一步用这4个因子与松毛虫危害程度建立多元线性回归模型，该模型可对松毛虫危害程度进行风险评估。

Based on cloud seeding data on April 5,2002 in Henan province,cloud seeding effects were evaluated by six methods,i.e.double contrast method of regional rainfall tendency control,regression analysis method of regional tendency correlation,multiple regression analysis method of regional tendency covariant,floating control historical regression method,cluster-analysis-based floating control historical regression method using rainfall as a covariant and CA-FCM using rainfall and atmospheric perceivable water as covariants.
