Pharmacology is a bridge discipline between medicine and pharmacy,betmeen basic medicine and clinical medicine,between life sciences and chemistry as well as material science. Phar?macology is closely related to many subjects,and is an indispensable subject in medical sciences. It plays an important role in the development of medical sciences. The main tasks of pharmacology development involve rational drug use,new drug research and development,and promotion of medical sciences and life sciences. During the whole process of new drug development,the development of pharmacolo?gy has played a positive role. As such,new drug research and development depends on the develop?ment of pharmacology. Pharmacology plays an important role in the development of new drugs and is involved in the whole process of research and development. Thus,it is a support subject for new drug development. Strengthening pharmacological research and improving the overall level of pharmacologi?cal in China are of great significance for promoting new drug research and development and ensuring ra?tional drug use.

Danshen-Radix Salviae Miltiorrhizae，is one of the common traditional Chinese medicines，which has been used clinically in the treatment of cardiovascular diseases more than 20 centuries.The active ingredients of Danshen has been researched 5 decades by the modern methods.Many researchers investigated the pharmacological effects of water soluble ingredients of Danshen-salvianolic acids in vivo and in vitro.The results demonstrated that salvianolic acids have different pharmacological effects such as potent antioxidative effects，scavenging free radicals，protect neural cells against injuries caused by anoxia， etc.In present paper，the pharmacological effects of salvianolic acids and the mechanisms of their actions are reviewed based on the research results obtained in our laboratory and other authors.

Neurodegenerative diseases are complex nervous system disorders as a result of myelin damage,synapses loss and/ or neuron loss. The pathogenesis of these diseases is still not completely clear. Protein kinases play an important role in both normal nerve cells and neurodegenerative disorders. lnhibitors of protein kinases can effectively regulate the physiological function of nerve cells and prevent the development and progression of the disease. This article reviews protein kinases and their inhibitors involved in Alzheimer disease,Parkinson disease,Huntington disease and other neurodegenerative diseases.

Thioredoxin-interacting protein (TXNIP), also known as vitamin D3-up-regulated protein (VDUP1), is an endogenous inhibitor of thioredoxin (Trx), which regulates the cellular reduction-oxidation (redox) state. TXNIP regulates cellular survival, apoptosis and inflammation induced by glucotoxicity, heat shock and mechanical pressure. The above functions of TXNIP are regulated by carbohydrate response element binding protein (ChREBP) and AMP-dependent protein kinase (AMPK). In recent years, numerous studies showed that TXNIP is involved in diabetes and diabetic complications. On the one hand, TXNIP functions in diabetes by increasing insulin resistance and hepatic gluconeogenesis. TXNIP expression is induced by high glucose, which is implicated in pancreatic beta cell glucotoxicity and endothelial cells dysfunction. TXNIP may contribute to the development and progression of diabetes and its vascular complications. TXNIP may be a new target for diabetes and its vascular complications therapy.

High-throughput screening is a regular approach available for identitying new lead compounds for the growing validated drug targets in drug screening. However, it has also introduced a large number of peculiar molecules which interfere drug screening. Pan assay interference compounds (PAINS) interfere with the progress of drug screening in various ways, such as interfering with a biochemical assay, modifying the protein, aggregate-based inhibitors and so on. So it is of vital significance to remove them. This paper has consulted the concept, category of PAINS and reviewed the way of PAINS interfering and the countermeasures to cope with them to direct the approach of high through screening and improve the hits percent.

Phosphodiesterases(PDEs) is the only protein enzyme family,which catalyze the hydrolysis of cyclic nucleotide second messages(cAMP and cGMP).PDEs regulate many physiologic and pathologic processes.Recent advance showed that PDE7 hydrolyze cAMP exclusively and is divided into PDE7A and PDE7B. PDE7 mainly express in immune and inflammatory cells.The selective inhibition of this family generates profound,functional effects and PDE7 has been used as a therapeutic target for diseases related with inflammation,such as chronic obstructive pulmonary disease(COPD),rheumatoid arthritis and Alzheimers disease(AD).

AIM: To apply high throughput screening methods to research Xiaoxuming Decoction's effective components combination and its action mechanism. METHODS: We studied the effects of 240 sequential components of Xiaoxuming Decoction (L1-L120,A1-A120) on anti-A? neurotoxicity、anti-H_2O_2 damage、anti-glutamic acid damage and ?-secretase activity. RESULTS: We evaluated these results of screening comprehensively,and found several components of Xiaoxuming Decoction (L1-L40,A30-A60,A100-A120) had the potential effects of listed before.So the combination of these components was regarded as the effective components combination of Xiaoxuming Decoction for anti-Alzheimer's disease. CONCLUSION: Xiaoxuming Decoction had effective protection against Alzheimer's disease through multi-component and multi-target.High throughput screening methods will push the development of Chinese traditional compound prescription greatly.

AIM: To establish the model of aging rats and observe the effect of the group of effective components of Xiaoxuming Decoction(XXM)on aging rats. METHODS: D-galactose and rotenone were used to establish aging animal model.The ability of learning and memory were measured by using Morris water maze test.Then, the content of GSH and MDA,the activity of SOD,the activity of AchE and ChAT in rats'brain were measured. (RESULTS): D-galactose could induce aging like indicators in rats:decrease the content of GSH and the activity of SOD,and increase the content of MDA,but have no effect on AchE and ChAT.It showed that GEC could improve the ability of learning and memory and ameliorate biochemistry function in rats with aging induced by D-galactose. CONCLUSION: These results suggest that GEC of XXM could improve the responses of aging rats and these effects may be related to its ability of antioxidation.

Reactive oxygen species (ROS) play a very important role in vascular homeostasis both physiologically and pathophysiologically. The imbalance between production and metabolism of ROS contributes to various vascular diseases. Recent studies have demonstrated that ROS regulated the redox-sensitive protein kinases in the signal transduction pathways,affected the activities of these kinases, and thus modulated the gene expression.
