Objective To explore the antagonistic effect of Schistosoma japonicum soluble adult worm antigen (SWA)and solu-ble egg antigen (SEA)in the mice with type 1 diabetes.Methods The 24 successful modeling type 1 diabetes mice were randomly divided into three groups (A,B,C group,n=8).SWA and SEA of Schistosoma japonicum were prepared.Mice in A group were immunized by abdominal subcutaneous multi-point injection SWA.Mice in B group were immunized by abdominal subcutaneous multi-point injection SEA.And mice models of C group were immunized by PBS instead of antigen through abdominal subcutaneous injection.The mice got immunization once a week,a total of four times.4 weeks later,the mice were sacrificed,and serum speci-mens were collected for the determination of serum levels of IL-4 and IFN-γby double-antibody sandwich ELISA,while pancreas tissues were collected and the pathological changes were observed.Results The serum IL-4 level of B group [(23.87 ±4.85)pg/mL]was higher than C group [(4.39 ± 0.56 )pg/mL],with significant differences (P < 0.01 ),while the serum IFN-γ level [(271.85±26.04)pg/mL]was lower than C group [(362.79 ±32.50)pg/mL],also with significant differences (P <0.01).The serum IL-4 and IFN-γof A group were (5.09±0.37)pg/mL and (379.56±34.47)pg/mL,which had no difference with C group (P >0.05).The islet structure of mice in B group was not intact,however,the lymphocytic infiltration in B group was less than C group,and there was no lymphocytic infiltration in pancreatic islets in B group.Compared with C group,the pancreas of mice in A group did not have significant changes,lymphocytes infiltration was still visible in islets.The number of residual islet cells de-creased,and visible minority islet structure was destroyed.Conclusion SEA of Schistosoma japonicum has certain antagonism effect on type 1 diabetes in experimental mice.Its mechanism may be the reduction of Th1 response and the enhancement of Th2 response through increasing IL-4 level and decreasing IFN-γlevel.

The articles concerning intensive effect and progress of interventional therapy for hepatocellular carcinoma (HCC) recurrence were comprehensively reviewed. Along with unceasing abundance of all interventional methods (including transcatheter arterial chemoemblization (TACE),percutaneous dehydrated ethanol injection,radio frequency ablation,percutaneous microwave therapy,argon-helium cryoablation,high-intensity focused ultrasound and radionuclide interventional therapy,etc),combined interven-tional therapies mainly TACE were increasingly appreciated in postoperative HCC recurrence,but still have to be further standardized. With further emerging and maturing of new technologies,such as antiangiogenesis,gene therapy and targeted therapy on HCC metastatic and recurrence specific cycle; the effect of combined therapy will be further promoted. Interventional therapy will play an important role in the prevention and treatment of postoperative HCC recurrence in the foreseen furture.

The interventional therapy of chemoembolization is the first management of choice in treating unresectable hepatic carcinomas but with some side effects including liver function damage and bone marrow restraints which may affect the patients'life expectancy and living quality in the long run.The advancement of the combination of interventional treatment with Chinese drugs in managing liver carcinomas is a special presentation by the auther for further recommondation.

Basic research in interventional radiology,including transcatheter artery perfusion especially,is progressing slowly due to lack of proper method.Microdialysis technique,a kind of accurate sampling technique in vivo,may help to solve the problem.Just as its name implies,microdialysis means tiny dialysis with advantages of authenticity,exactness and less error.Furthermore it has been applied widely and should be received with great attention and popularity.

By studying on extraction technology of desertliving cistanche polysaccharides, it provided evidences for development and utilization of cistanche. Anthrone-sulfuric acid method was used in the measurement of desertliving cistanche polysaccharides. The yield of desertliving cistanche polysaccharides was used as index. Different types of extraction methods were compared. Then, the extraction process was optimized by orthogonal experiment. The results showed that the best extraction process was Tween-60 ultrasonic cooperated. The best extraction process was when the mass concentration of Tween-60 was 0.5%, solid-to-liquid ratio was 1:25, temperature was 60℃, and the extraction time was 30 min. The extraction yield of desertliving cistanche polysaccharides was 8.17%. It was concluded that this extraction technology was reasonable and reliable, which can be used in the development and utilization of cistanche.

Objective To improve the teaching methods for doctor-patient communication skill of medical interns.Methods The present situation and the importance of doctor-patient communication were analyzed.The training model of doctor-patient communication was designed including the aspects of effective training content,training methods and assessment tools,etc.Totally 178 interns in our hospital between June and August 2013 were selected and were divided into two groups.The newly designed training model was applied in students in group A while routine training was applied in students in group B.Doctor-patient communication ability of interns was tested through writing instruments and on-the-spot communicating and investigating satisfaction degree of patients.SPSS 13.0 was applied to do statistical analysis and t test and Wilcoxon were used.Results Score of instrument writing and on-the-spot communication were higher in group A than in group B [Group A:(20.36 ±2.85),(21.18 ± 2.93) ; Group B:(14.79 ± 2.61) and (13.94 ± 3.07)],with statistically significant differences(P=0.000).In addition,according to a survey of 406 patients of group A,367 patients of group B,group A students' satisfaction degree after the training was significantly higher than that group B(59.85％ vs.11.99％)(P=0.000).Conclusion The newly designed doctor-patient communication training model can enhance the doctor-patient communication skills.
