Caffeine - A derivative of coffee, is an efficient arouser of central nervous system capable to drive away fatigue, and improve renal circulation. Its stimulation on the cerebral cortex activates Neurotransmitter receptors in the cell membrane; the adenylyl cyclaseactivated on the other surface of the cell catalyzes Adenosine Triphosphate, forming Cyclic adenosine monophosphate, and thus set off series of bio-chemical reactions, like increase of passionate feel, prompt recovery from fatigue after working etc..

咖啡因—由于咖啡本身具有兴奋神经中枢，消除疲劳，增加肾脏血流量的作用，通过对大脑皮层的刺激，使神经递质作用于细胞膜受体，激活了膜另一侧的腺苷酸环化酶，被激活的腺苷酸环化酶催化三磷酸腺苷环化酶，被激活的腺苷酸环化酶催化三磷酸腺苷形成环磷酸腺苷，从而引起一系列生化反应，如增加愉快感和消除事后疲劳等。

The results demonstrated that the intracellular pH change was different when the Hela cells was treated with different anti-tumor drugs, some would caused intracellular acidification, some would caused ntracellular basification, and some would barely caused pH change. The single living Hela cells uptaken with the ratiometric pH nanosensor was also imaged with laser confocal microscope, which were treated with anti-tumor drugs.

In most known examples, the affected proteins are enzymes, as in phenylketonuric oligophrenia which affects 1 in 10,000 of the population. It is due to deficiency in the liver cells of phenylalanine hydroxylase, which normally converts phenylalanine to tyrosine, and brain damage apparently results from raised blood and cerebrospinal fluid levels of phenylalanine and its metabolites.

Wenxin capsule can promote endolethial cells releasing CO and synthesing 〓, enhance activity of HO, induce angiectasis through activating guanylic cyclase and adenglate cyclate of intracellar of vessel smooth muscle cell to enhance content of intracellar cGMP and AMP. 3. Wenxin capsule can inhibit releasing of platelet activiting factor 〓 which inhibit platelet aggregation and have antithrombosis function. 4. Wenxin capsule can promote activity of t-PA, reduce activity of PAI-1, strengthen fibrinolytic function, therefore inhibit fibrin disposition. 5. Wenxin capsule can inhibit synthesis of smooth muscle cellular DNA. Its function don't kill it directly but prevent transformation from period Go to peried S. 6. Wenxin capsule is an effective prescription of anti-coronary atherosclerosis atherosis. The results of image pattern analysis tastifies that area of lipid plaque in treating group reduce 54% and 58% in contrast with that in control group. The results of light, electro- microscopy show that structure of endolethial cell and smooth muscle cell in treating group is more integral than that in control group.

其作用机制之一是由于该药具有良好的调脂降脂作用，其不仅能明显降低血清LDL-c及升高HDL-c含量，且能有效阻止TC沉积于血管壁，从而保护内皮细胞结构完整；此外，温心胶囊尚具有明显的抗氧化作用，该药不仅能明显降低血浆LPO含量，且能提高SOD活性，同时其对血红素在细胞内代谢的调节作用也参与了抗氧化过程。2 温心胶囊能明显促进内皮细胞释放CO及合成〓，提高HO活性，通过激活血管平滑肌细胞内鸟苷酸环化酶及腺苷酸环化酶引起细胞内cGMP、AMP浓度增加而引起血管舒张。3 温心胶囊能明显抑制血小板激活因子〓的释放，从而抑制血小板聚集，抗血栓形成。4 温心胶囊能明显提高t-PA活性，降低PAI-1活性，增强纤溶功能，从而抑制纤维蛋白沉积。5 温心胶囊能明显抑制平滑肌细胞DNA合成，其抑制作用不是直接杀伤抑制，而是阻止细胞由Go期向S期转化。6 温心胶囊是抗冠状动脉粥样硬化的有效制剂，图象分析结果证实，该药治疗组脂斑面积比对照组缩小了54％和58％，光电镜结果显示内皮细胞及平滑肌细胞结构较为完整。

Results: The changes following hydrocortisone intervention of rats could be identified by PCA, and the kidney deficiency syndrome rats entered a state of "hyperfunction", involving a series of changes in metabolic pathway and metabolic network. The response integral area of lactic acid (δ 1.37) increased, indicating the accumulation of metabolites of lactic acid. The amount of dimethylamine (δ 2.72) also increased, indicating that the disorder of kidney function was related to kidney-deficiency syndrome. The response of creatinine (δ 3.87), asparaginic acid (δ 2.83), taurine (δ 3.44, 3.28), and hippurate (δ 7.84, 7.56, 7.64, 3.97) all decreased significantly, indicating that the hydrocortisone might cause adrenal cortex excretion injury. The response integral area of succinate (δ 2.41) and citric acid (δ 2.53, 2.68) decreased, which was usually caused by disorder of the mitochondrial function.

结果：PCA方法处理肾虚证和空白对照大鼠尿液数据显示，两组大鼠的数据可以在得分图实现分类，与对照组比较肾虚组大鼠由于氢化可的松诱导，大鼠机体进入一个过消耗后衰弱的状态，相关代谢发生显著变化，乳酸(δ 1.37)代谢发生堆积；二甲胺(δ 2.72)的含量增加，提示肾虚与肾功能异常是密切相关的；天冬氨酸(δ 2.83)，牛磺酸(δ 3.44， 3.25)，马尿酸(δ 7.84， 7.56， 7.64， 3.97)，肌氨酸(δ 3.87)等的相对积分面积明显下降，这预示糖皮质激素可能引起了肾上腺皮质分泌功能的损害；琥珀酸(δ 2.41)和柠檬酸(δ 2.53， 2.68)是三羧酸循环能量代谢及糖酵解的中间产物，其含量的降低，通常是由于线粒体功能紊乱所引起。
