OBJECTIVE:To determine the content of emodin in Changtong oral liquid.METHODS:HPLC was used.The stationary phase was Nova-Pak C 18 column and the mobile phase was methanol-0.1%phosphoric acid solution(85∶15).The UV detection wavelength was254nm.RESULTS:There was a good linear relationship within the concentration range of0.48~2.4?g/ml of emodin in Changtong oral liquid(r=0.9998).The average recovery was99.73%(n=5),RSD=1.42%. CONCLUSION:This method is simple,fast and accurate.

Objective To investigate the clinical operating skills of the ultrasound-guided percutaneous transhepatic bile duct puncture drainage(PTCD),and improve the success rate.Methods 60 cases of tumor-induced obstructive jaundice underwent ultrasound-guided percutaneous transhepatic bile duct puncture drainage were retrospectively analyzed and summarized.Results 60 cases were all punctureed successfully,and the success rate was 100%.A puncture needle patients which was successfully accounted for 88% (53 cases).No obvious puncture complications were found.Conclusion Preoperative fully prepared for surgery the appropriate action can improve the ultrasoundguided percutaneous bile duct through the success rate of bypass,there is helpfal to reduce the puncture complications.
