Objective To evaluate the clinical effect of ultrasound-guided percutaneous transhepatic cholangial drainage (PTCD) combined with endoscopic retrograde cholangio-pancreatography (ERCP) in treating malignant obstructive jaundice, and to discuss its technical points. Methods A total of ten cases with malignant biliary obstruction were enrolled in this study. After the failure of ERCP treatment, the patients had to be treated with ultrasound-guided PTCD immediately. The guide-wire was inserted into the duodenum through intrahepatic bile duct and common bile duct to connect with ERCP, which was followed by the biliary stent implantation or the removal of physical factors causing obstruction. The clinical results were analyzed. Results Technical success was obtained in all 10 cases. In the patients who underwent a successful guide-wire docking with ERCP the postoperative serum bilirubin was significantly decreased. The main complications were fever, elevation of amylase and transient bloody bile. Conclusion With the help of docking technique the combination use of ultrasound-guided PTCD and ERCP is a new tentative treatment for malignant obstructive jaundice after the failure of initial ERCP treatment. This technique carries promising value in clinical practice as it can significantly increase the success rate of ERCP.

Objective To study the effect of Shaoyaozhitong Mixture on stageⅢ-Ⅳendometriosis, and explore its mechanism. Methods Ninty-five cases of stageⅢ-Ⅳ endometriosis were randomly divided into three groups. The traditional Chinese medicine (TCM) group (31 cases) was treated with Shaoyaozhitong Mixture, the GnRHa group (31 cases) was treated with Triptorelin Acetate for Injection, while the expectant group (33 cases) received no medications. The changes of CA125, TNF-α and VEGF levels, visual pain score and SF-36 score, total effective rate, pregnancy and recurrence were compared. Results There were significant increases in CA125, TNF-α and VEGF levels, visual analogue pain score and SF-36 score in all the three groups after treatment (P<0.05). The decline of CA125, TNF-αand VEGF levels and visual analogue pain score in TCM group and GnRHa group was significantly faster and greater than that of the expectant group (P<0.05). The total effective rates of TCM group was 83.9%(26/31), GnRHa group was 87.1%(27/31), and expectant group was 60.6%(20/33), TCM group and GnRHa group were superior to the expectant group, respectively (P<0.05). The pregnancy rate was higher and recurrence rate was lower in TCM group and GnRHa group than that of expectant group, but there was no statistical difference (P>0.05). Conclusion Shaoyaozhitong Mixture is effective in treating endometriosis by inhibiting the growth of ectopic endometrium.
