The main contents of this dissertation are summarized as follows: ( 1) Adopt a new Decision Support System ( DSY) to design the model of the personalized service system, which emphasizes analyzing resources and identifying readers' interests, in a digital library.

Conclusion The improvement of NO and PGE_2 content, and the promotion of vascular regeneration at the bottom of the ulcer may be one of the mechanisms of DSY on gastric ulcer.

结论提高血清NO、血浆PGE2的含量，促进溃疡底部血管生成可能是丹参饮抗胃溃疡的作用机制之一。

Results The ulcer index in DSY and ranitidine group was obviously smaller than that in the model group ( P < 0.01).

结果丹参饮组和雷尼替丁组的溃疡指数均明显小于模型组（P＜0.01）；

Conclusion DSY has protective effects to improve the experimental myocardial ischemia in rats, which is closely related to anti-peroxidation.

结论加味丹参饮可明显减轻大鼠心肌缺血损伤程度，对实验性心肌缺血具有显著的保护作用，这与其抗过氧化作用密切相关。
