OBJECTIVE:To establish the quality standard of shuangbai tincture.METHODS:The rhubarb and cortex phellodendri in shuangbai tincture were identified qualitatively by TLC.The content of emodin in this preparation was deter-mined by HPLC.RESULTS:In the TLC of the testing samples,the corresponding positions of standard rhubarb and standard cortex phellodendri respectively showed the same color of speckles.The linear range of emodin was0.1176?g～2.3520?g(r=0.9994)and the average recovery was98.81%(RSD=0.45%).CONCLUSIONS:This method is simple,accurate and repro-ducible,and suitable for the quality control of shuangbai tincture.

OBJECTIVE: To evaluate the use of oral hypoglycemic drugs in our hospital in order to provide an reference for rational use of drugs in clinic. METHODS: DDDs, sales volume, and daily expenses of drugs in our hospital from 2001to 2003 were analyzed with the method of DDD analysis. RESULTS: The varieties, quantities and sales volumes of oral hypoglycemic drugs increased year by year. The top 3 hypoglycemic drugs in respect of DDDs were dimethylbigmide, gliclazide, and glipizide. The top 3 hypoglycemic drugs in respect of sales volume were glipizide, acarbose, and dimethylbimide. The ratio of sales volume sequencing to that of DDDs was between 0.2～4. CONCLUSIONS: Gliclazide and dimethylbimide are most widely used and their prices are reasonable; Acarbose is expensive, and its sales volume has not grown in pace with DDDs.

OBJECTIVE:To discuss the correlation between antibacterial drug use and the bacterial drug resistance in the hospital where the authors work.METHODS:The DDDs of antibacterials during the period from2002to2004were counted,and the correlation between DDDs and bacterial drug resistance was analyzed.RESULTS:The total DDD of the antibacterials increased by47.14%in this period.To2004,the resistance rates of4major pathogens to9commonly used categories of antibacterials were more than44%.The DDDs of amoxicillin/clavulanate potassium,ampicillin sodium/sulbactam sodium,cefoperazone sodium/sulbactam sodium increased by4,19.8and7times,respectively in the3years,the resistance rates of pathogens to which also evidently increased,among which staphylococcus aureus increased by over22%.CONCLU_ SION:The hospital should strengthen the administration of antibacterial drug use in many ways to reduce the bacterial drug resistance.
