OBJECTIVE:To establish the method for the content determination of2,3,5,4'—tetrahydro-xystilbene—2—O—?—D—glucoside in Yangxueshengfa capsules by RP-HPLC.METHODS:Alltima-C 18 was used as the chromatographic column;the acetonitrile-water(15∶85)was taken as the mobile phase with flow speed at1.0ml/min and detection wave?length at320nm.RESULTS:In the range of0.45?g～2.26?g,2,3,5,4'—tetrahydro-xystilbene—2—O—?—D—glucoseide were in direct proportion to the peak area value(r=0.9996),the mean recovery rate was98.32%(RSD=1.58%,n=6). CONCLUSION:This method was simple,convenient and accurate,which can be used for the content determination and the quality control of Yangxueshengfa capsules.

Objective To study the clinical effect and application value of micro-plasma beam joint radiofrequency treatment for the striae of pregnancy.Methods 21 female patients with the striae of pregnancy were included in this study,treated from the July 2012 to March 2014,aged 25-37 years;and time of the striae was from 3 months to 7 years.Micro-plasma radiofrequency technology was used to treat the striae,with interval of 30 days each time for total seven months.The total effective rate,satisfaction,and the adverse reaction were evaluated after the treatment.Results 21 patients included grade 4 in 6 cases,grade 6 in 10 cases,grade 2 in 4 cases and grade 1 in 1 case;the total effective rate was 95.2％ (20/21).Satisfactory degree was for the level C in 6 cases,B in 14 cases,and A in 1 case,with total satisfactory rate of 95.2％ (20/21).Adverse reactions included mild pigmentation in 2 patients after scab skin falling off,and disappeared at the end of the treatment course.Conclusions Micro-plasma beam combined with radio frequency in treating the striae of pregnancy has clear curative effect and good clinical application value.
