This article reviews recent advances in our understanding of the structure,drug interaction mechanism…….. In view of its wide localization ….. of P-gp,and its ATP-dependent outward-oriented transport, P-gp actively participates in intestinal secretion,bloodtissue barriers,and …………... Moreover,the importance of P-gpmediated drug interactions in clinical practice can hardly be underestimated,since it may result in severe side effects,such as digitalis drug interaction. Polymorphism or single nucleotide polymorphism (SNP)associated with P-gp may exert a significant effect on the pharmacokinetic behavior of its substrates,a fact ……..In addition,dietary components and pharmaceutical excipients may modulate P-gp activity,and as a result affect in vivo drug disposition and therapeutic efficacy;examples include grapefruit juice,Pluronic P85,PEG 300,etc..In summary,it should be emphasized that P-gp is an integral component in the process of drug discovery,development strategy,and clinical therapy.

Definitions
Pharmacology has been defined as an experimental science that studies changes brought about in vivo and in vitro by chemically acting substances, whether used for therapeutic purpose or not. In the broadest sense, pharmacology is the science of studying the effect of drugs on living organisms. It attempts to describe the biological response produced by drugs and to define the underlying mechanisms by which the responses are generated.

Type D: delayed reaction These reactions refer to carcinogenic and teratogenic effects. These reactions are delayed in onset and are very rare since extensive mutagenicity and carcinogenicity studies are done before drug is licensed. Type E: end-of-use reactions（withdrawal reaction） Abnormal physical or psychological features that follow the abrupt discontinuation of a drug. e.g. Sudden cessation of the use of an antidepressant(抗抑郁药) can deepen the feel of depression significantly

Unit Four
Most drugs produce effects by combining with biological receptors. The chemical bonds that form between drug molecule and receptor are usually reversible. The ease with which drug and receptor interact is influenced by the degree of complementarity of their respective threedimensional structures. For this reason, minor chemical modification of a drug may produce profound changes in its pharmacological activity.
At one time, it was essential for the physician to have a broad botanical knowledge, since he had to select the proper plants from which to prepare his own crude medicinal preparations. However, fewer drugs are now obtained from natural sources, and, more importantly, most of these are highly purified or standardized and differ little from synthetic chemicals.

• 化学是研究物质的科学。在学习 化学这一点上，我们不能将“物质” 这个词仅限于它的科学定义上，而 应该对它的实际含义有整体的理解。 物质的常见的例子如水、糖、盐、 铜、铁、氧气以及你能想到的其他 许多东西。
Inorganic chemistry

Organic chemistry
• The chemistry of carbon compounds.

Benjamin Franklin
• He was a leading author and printer, satirist, political theorist, politicain, scientist, inventor, civic activist, statesman and diplomat. As a scientist he was a major figure in the Enlightenment and the history of physics for his discoveries and theories regarding electricity. He invented the lightning rod, bifocals, the Franklin stove, a carriage odometer, and a musical instrument.
• The only major carbon compounds considered inorganic are carbonates (for instance, calcium carbonate which is one of the major forms of mineral on Earth) and oxides, such as carbon dioxide and carbon monoxide.

科学在现代社会中起着很重要的作用，
以至于没人敢说他理解他所生存的世界， 除非他理解了科学。（在现代社会，科 学扮演着如此重要的角色，以至于没人 能确定他了解这个他所生活，or生存的 世界，除非他对科学有很好的理解。） （只有真正理解科学的人才能明白科学 在现代社会中扮演的重要角色。）
化学与物质
• 为什么学习化学？正如本杰明，弗兰克 林之前所陈述的那样，一个重要的原因 是----正是通过化学及其相关科学，人类 获得了力量，思想的力量以及超越物质 的力量。大约200年前，Franklin提到科 学在飞速发展。我们知道科学发展的速 度不断加快，到目前为止，由于科技的 进步，我们所生活的世界与弗兰克林时 代相比已经发生了巨大的变化。
