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 investigate the malaria knowledge of CDC staff and their demands on related training in malaria non⁃endemic areas,so as to provide the reference for planning the appropriate curriculum. Methods All the participants who were the staff of county CDCs all over Qinghai Province and attended the provincial training workshop were surveyed. A self⁃administered questionnaire survey was carried out and the data was statistically analyzed. Results A total of 115 participants were involved in this survey. They were mostly(85.21%)from county CDCs. The general knowledge of malaria among the respondents was well,and the average rate of correct answers was 70.35%. However,the answers to the general knowledge of malaria and anti⁃malaria treatment were not well enough. The rates of correct answers were 61.96% and 48.99% respectively. The differences among the groups of job title ranking,department of working and level of CDC were not significant(F = 0.13-2.02,all P > 0.05). The number of correct answers was significantly increased after the training course. The average score after the training was 79.20±15.16 while the pre⁃training score was 70.34±17.46(t = 3.86,P < 0.05),especially in the answers to general malaria knowledge and malaria surveillance and response(t = 4.30,4.97,both P < 0.05). The general knowledge of malaria was considered as the most need of training as 80% of the respondents voted“Yes”,according to the demand analysis. There was no significant difference among the different groups(F = 0.61-3.11,both P > 0.05). Conclusion The malaria knowledge is well mastered by the staff of CDCs in Qinghai Province,and the further training courses are requested and addressed in the target areas such as general malaria knowledge,anti⁃malaria treatment,malaria surveillance and response.
