In this paper,the background,present situation,problem and tactics of GAP(Good Agricultural Practice)of chinese materia medica are discussed.The main problems of the yielding of chinese materia medica are as followings:(1)Lack of close controlling standards and scientific detecting methods.(2)Decentralized management.low benefit and low controllability.(3)The pesticide residue and heavy metal content exceeding the provided standard.(4)Production and marketing disjointed,supervising and controlling intensity in the whole yielding process not enough.Thus,3 measures are put forward:(1)Strengthening the management of the quality of chinese materia medica,formulating strict and unitary quality controlling standards,setting up scientific checking methods.(2)Developing genuine drugs,establishing famous brands.(3)Establishing green chinese meateria medica yielding bases,to make the Chinese Materia Medica utilization sustainable.

OBJECTIVE：To prepare compound clemastine cream(COC)and to evaluate its clinical efficacy for the treatment of seasonal contact dermatitis in the face.METHODS:The preparation was obtained by traditional o/w method.94 outpatients and inpatients were randomly divided into active group(COC group)and control group(Kangfulire ointment group).RESULTS:The healing rate and the total efficient rate were significantly higher than those of control group(p＜0.01，p＜0.05).CONCLUSION:COC has reliable clinical efficacy and has little side effects,so it is one of the specific preparations for the treatment of contact dermatitis and it can be widely used in the clinics.

OBJECTIVE：To study the hemorheological paramenters in rat with hepatic fibrosis. METHODS:Hepatic fibrosis in rat was induced by CCl4 treatment. Whole blood viscosity, plasma viscosity, Hematocrit(Hct) and dynamic parameters of red blood cell(RBC) were investigated. RESULTS:As compared with the normal group, the hemorheological parameters such as whole blood viscosity, plasma viscosity, Hematocrit(Hct), RBC's aggregation and rigidity were increased obviously. CONCLUSION:High blood vicosity and low RBC's deformation ability can lead to blood circulation obstacle, thus will aggravate hepatic fibrosis.

OBJECTIVE：To observe the antisepsis and anti-inflammatory action of Xiaoyan tablet.METHODS:Using physiological saline as control,the antiinflammatory effiects on the oncotic extent of the ear auricle of the mouse caused by xylene and swollen toes of rat caused by rat mucllago. and the antibiotic effects on staphylococcus aureus,beta hemolytic streptococcus,pneumococcus,bacillus influenzae were studied.RESULTS:The inflammatory effects of taking medicine group was dramatic compared with physiological saline group(P＜0.01).Its antisepsis action is equivalent to oral liquor of double coptis chinensis.CONCLUSION:The antisepsis and anti-inflammatory action of Xiaoyan tablet is better.

OBJECTIVE：To test and verify the piping cleaning effect in infusion solution productive process.METHODS:Targets of final washing water of pipe were determined.RESULTS:Targets of final washing water of pipe were that electrical conductivity of entrance of pipe was equal to that of exit of pipe essentially,limitation of bacteria and endotoxin were as follows:＜50CFU/ml,＜0.25EU/ml.CONCLUSIONS:According to the clean rules laid down by pharmaceutical Factory of Shanquan,Jinan,The desired cleaning effect of the pipe of infusion solution can be achieved.

OBJECTIVE：To study the main aspects of quality control of dexamethasone liposomes.METHODS:The structure of liposomes was studied with negative staining method of TEM.K-ratio spectrophotometry was wsed to determine the contert,and the Macrosep was wsed to seperate the entrapped from free drugs.RESULTS:An excellent linear relationship was obtained with the range of 4～52μg/ml,the average recovery percent was between 98.28%～99.71%.The entrapment efficiency was one of the important parameters of liposomes quality control.It was related with the clinical effect directly,the entrapment efficiency was more than 80%.CONCLUSION:This method is accurate,quick and reproducible.

OBJECTIVE：To study the enhancement effect of dipentene in the transdermal absorption of tinidazole.METHODS:In vitro,by means of traditional method to compare the enhancement effect of dipentene with azone at difference concentrations in the transdermal absorption of tinidazole.RESULTS:andCONCLUSION:It was showed that various concentrations of transdermal enhancers could promote absorption of tinidazole in different degrees and 4% Azone and 3%dipentene were the most effective.

BJECTIVE:To apply the radial basis fuction neural network for the spectrophotometric analysis of three components combined preparation.METHODS:Aminopyrine and antipyrine in Antongding injection were determined by radial basis fuction neural network UV spectrophotometry,barbitial was determined with absorbance substraction technique.RESULTS:Compared with BP network,the radial basis network was better in robustness of netwrok,training time and the forcast accuracy.CONCLUSION:The three components of Antongding injection can be determined accuratly by the radial basis fuction network spectrophotometry.

To assess the drug utilization and tendency of progress of oral hypoglycemic agents in our hospital and to provide references for rational administration clinically. Methods: DDDs, sales quantities, sales expenses and the ratio of sales expenses sequencing to that of DDDs in our hospital during the period of 2003 ～ 2005 were analyzed statistically with the method of DDDs analysis. Results:The top two antidiabetic drugs according to DDDs were melbine ( dimethyl diguanide) and gliclazide three successive years. The DDDs of acarbose increased dramatically. Which blood glucose regulatsry drugs ranked lower, the ratio of sales expenses sequencing to that of DDDs of glipizide and gliclazide controlled release pellets was equal or about, whereas that of rosiglitazone, acarbose(glucobay) and glimepiride was less than 1. Conclusion:The study shows that the drug utilization of oral hypoglycemic agents in our hospital is basically rational and is in accordance with the trend of advancement and drug therapeutic strategies of diabetes mellitus.

Hypoxia-inducible factor-1 (HIF-1) is a critical nuclear transcriptional factor mediating cell adaptive response to hypoxia in mammalian and human .It is the key mediator which modulates oxygen homeostasis exclusively .In the one hand , HIF-1 can protect and promote kinds of physiological processes , such as embryo normal development , cartilage and bone formation .In the other hand, it is also involved in lots of human deceases which is caused by ischemia and hypoxia , such as tumor, diabetes and its complica-tions.The molecular mechanisms of HIF-1 involved in these diseases have become a research hotspot and such studies will provide the new therapeutic means for these diseases , recent new drug researches have been focused on HIF-1 related signal pathway inhibitors , HIF-1 activity inhibitors, HIF-1 targeted therapy, etc.
