OBJECTIVE:To prepare rufloxacin hydrochloride gel and establish a quality control method of the gel METHODS:Carbopol940 was used as the gel base,the content of rufloxacin hydrochloride was determined with UV-spectrophotometry and the stability test was performed RESULTS:There was a good linearity of calibration curve of rufloxacin hydrochloride in range 2～10?g/ml,r=0 9 999,the average recovery was 99 53%,RSD was 0 38%(n=6) The gel was stable CONCLUSION:The design of the gel formulation is reasonable The gel can be prepared feasibly and is stable in quality,convenient in use

OBJECTIVE:To observe the clinical efficacy of Danhong injection and its impact on plsma levels of TNF-? and IL-6 in patients with acute cerebral infarction.METHODS:80 patients with acute cerebral infarction were randomly divided into two groups: 40 in control group were treated with conventional therapy, while the other 40 in treatment group with conventional therapy in combination with Danhong injection.The changes of neurologic function score(NIHSS), clinical effect and the plasma levels of TNF-? and IL-6 after 2-week treatment were compared between the two groups. RESULTS: There were signficnant differences in neurologic impairment score(NIHSS), clinical effect and the plasma levels of TNF-? and IL-6 between the treatment group and the control group after treatment (P
