ABSTRACT
OBJECTIVE:To provide references for the clinical research on the optimized therapeutic regimen in the treatment of cerebral infarction. METHODS:The medication information of 1 738 cases cerebral infarction patients in 8 tertiary grade A hospitals in Shandong province between January 2003 and January 2005 was analyzed statistically. RESULTS:The majority cases were administered with dehydrants,thrombolytic,drugs that could prevent platelet from aggregation,improve cerebral circulation and cerebral metabolism,meanwhile,they were given the combined treatment,chiefly the supporting treatment,the cure rate and improvement rate were 92.69%,the mortality was 3.45%,automatic (without cure)hospital discharge rate was 2.42%,the medication was rational. CONCLUSION:Multi-application,long course of treatment,high prices,heavy economical burden were often the cases in the treatment of cerebral infarction. It is essential to conduct pharmacoeconomics study so as to the lessen patients' economical burden and obtain an optimized therapeutic regime.
ABSTRACT
Objective To prepare a thermosensitive in situ gel system containing berberine hydrochloride for ocular use. Methods The in situ thermosensitive gel system of berberine hydrochloride was prepared by Poloxamer 407 (P407) and Poloxamer 188 (P188) as thermosensitive materials,the formulation was optimized by determining solution-gelation conversion temperature by using stirring method. The content of berberine hydrochloride was determined by HPLC. Results The gelation temperature of in situ thermosensitive gel containing berberine hydrochloride formulations lowered as the P407 concentration increased,as the P188 concentration increased gradually the gelation temperature initially increased to maximum and then decreased. The gelation temperature all increased after simulated tear fluid (STF) dilution. The fitted equation was established for the gelation temperature with the concentration of Poloxamer solutions after diluted by STF. An optimized formulation by Design-Expert software was freely flowing liquid at 29.7 ℃ and convert to a firm gel at 34.5 ℃ after STF diluted. Conclusion In situ thermosensitve gel system complies with the requirement for ophthalmic application and shows great potential in ocular application.
ABSTRACT
OBJECTIVE:To compare the therapeutic effect and cost-effectiveness ratio between chuanhuning and rib?avirin in treatment of viral pneumonia.METHODS:63patients with viral pneumonia were divided into chuanhuning and rib?avirin groups and pharmacoeconomic cost-effectiveness analysis was carried out.RESULTS&CONCLUSION:In treating viral pneumonia,there is a great disparity in price between chuanhuning and ribavirin,however,the costs of two groups were very close,and so were the cost-effectiveness ratios.Chuanhuning is better than ribavirin in paying.
