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)。

By the investigation of present situation, it is trying hard to find the reasons that cause this situation. And it discusses how to carry out an effective teaching method that called comment on reading inner Chinese teaching. That method advocates multiple reading and pays attention to the interaction during the process of comment reading. These ways have the aim of stimulating students' interest on reading. As teachers, we are trying to change the disadvantages in reading teaching process through fairish teaching strategies, and helping students to have well lifelong reading habits. Only do those things, the efficiency of teaching will enhance and the missions of reading teaching will genuine completeness at last.
