ABSTRACT
Objective To establish the method for simultaneous determination of epimedium glycoside and other 4 kinds of active ingredients in Xianling Gubao Capsules by three wavelength switching method. Methods An Waters Atlantis T3 C18 column (4.6 mm × 250 mm, 5 μm) was used with the mixture of acetonitrile-0.05％ formic acid solution as the mobile phase in gradient elution (0–5 min, 12％–20％ A; 5–15 min, 20％–55％ A; 15–35 min, 55％ A;35–55 min, 55％–76％ A; 55.1 min, 12％ A; 55.1–60 min, 12％ A). Detection wavelength was as follow: 0–30 min, 212 nm; 30–42 min, 246 nm; 42–60 min, 270 nm. The flow rate was 1.0 mL/min. The column temperature was 30 ℃. Results The calibration curves of asperosaponin Ⅵ, psoralen, angelicin, epimedin C, and icariin were in good linearity among the ranges of 101.6–3048 ng, 8.7–261 ng, 7.9–237 ng, 117.2–3516 ng, 78–2340 ng, respectively. In the instrument precision test, stability test, repeatability test, the RSD was less than 3％. The average recoveries were 99.83％, 100.35％, 100.59％, 100.60％, 99.72％, respectively, and all the RSD were less than 3％. Conclusion The method is sensitive, accurate, and separation effect is good, which can provide a basis for quality evaluation standard of Xianling Gubao Capsules.
ABSTRACT
Objective To investigate effect of serum apoptosis factor and long-term effect on medical abortion patients by sequential misoprostol. Methods 80 cases of early pregnancy patients who required termination pregnancy, were selected and randomly divided into 2 groups.40 cases in control group were treated with mifepristone 25mg oral, misoprostol 600μg, 4 times a day.40 cases in experiment group were treated with sequential use of misoprostol.Effect of medical abortion, survivin and caspase-3 were compared after 7d treatment.Gynecological inflammation, dysmenorrhea and infertility were compared for 2 years.Results Compared with control group, complete abortion rate of the experiment group was higher (P<0.05).The incidence of adverse drug reactions of the experiment group was lower than control group (P<0.05) after 2 years follow.up.Compared with the control group, HCG,E3 and P of experimental group were lower (P<0.05).After 7 days of medication,survivin decreased,caspase-3 increased,compared with control group, survivin of the experiment group was lower, caspase-3 was higher ( P<0.05 ) .Conclusion Misoprostol sequential can improve the success rate of medical abortion abortion, reduce the complications of abortion, presumably with the inhibition of survivin expression, is associated up regulation of caspase-3 levels.
