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.

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.

Objective: To explore the differences between the internal social adaptation and external social behaviors of freshmen. Methods: Make a survey of 198 freshmen on the internal adaptation and external by General Well-Being Schedule and Undergraduate Social Adaptation Questionnaires. Results:Freshmen' social adaptation mainly involves three factors: interpersonal communication, the state of campus life and performance of studies. The Cronbach alpha of 3 factors were 0.82, 0.87 and 0.90,and the re-test reliability was r=0.73 (P

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 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.

BACKGROUND: With follow-up prolonged, more patients received total hip replacement need to revision. Periprosthetic ostaolysi, accompanied by aspetic loosening, would be aggratate, which lead to artificial joint loosening, eventually, result in joint renovation. OBJECTIVE: To observe the therapeutic effect of non-bone cement prosthesis on joint renovation following total hip replacement. METHODS: Totally 41 patients (41 hips) received renovation following total hip replacement at the Shenyang Orthopaedics Hospital from 2004 to 2009 were selected. They were renovated by Circumflex type total hip joint and press fit type non-bone cement type total hip joints. Eight cases had acetabular deficiency, 17 cases had Gustillo Ⅰ-Ⅱ acetabular loosening, and 8 cases had Gustillo Ⅲ acetabular loosening. All these patients were received spiral mortar shaping of pure titanium directly or combined with particle bone graft. Eight patients had Gustillo Ⅳacetabular loosening combined with bone defects, who adopted particles to plant the bone, rebuilt the hip mortar by titanium mesh, and shaping with bone cement. Non-bone cements prosthesis or lengthened prosthesis, as well as bone graft, was selected individualized. The cerclage band could be used if necessary. RESULTS AND CONCLUSION: Eight patients received titanium mesh and bone graft could do un-bearing exercise, and the remained patients could perform bearing exercise at day 3 after renovation. In the 6-66 months follow-up, no prosthetic displacement or subsidence could be found. No patients need a second renovation. Harris scores were increased from 32.6 before operation to 88.1 after operation. X-ray film showed that the bone density was increased in parts of patients. The results demonstrated that hip renovation using non-bone cement prosthesis can received an excellent short-term therapeutic effect, but the long-term effect needs to be explored.

Managed care insurance is growing into the mainstream health insurance model in the United States. The differences between this and the traditional health insurance lie in their economic model, their autonomy of consumers in their choices of suppliers, their economic risk exposure for clinicians, their effect on utilization review and their impact to clinical decision-making. Managed care can only, in terms of cost constraints, affect or limit the autonomy of medical decision, instead of making decisions in lieu of clinicians. Under managed care, both the professional risk of clinicians and health benefits of consumers are exposed to obvious negative influence. In the meantime, the model is facing growing difficulties in the future for the market itself. In this regard, prudence is required to introduce managed care in China.

Objective To evaluate and compare the advantages and disadvantages and the clinical applica- _ tion between abdominal hysterectomy (AH) and laparoscopically hysterectomy ( LAH) on the benign lesions of Non-prolapsed Uterus. Methods 400 patients with benign lesions of Non-prolapsed Uterus were divided into two groups. They were AH group (202 cases) and LAH group (198 cases). The effects of clinical treatment of the two groups were compared. Results In LAH group anal exhaust time,postoperative morbidity,length of stay were less than those in AH group,the difference was statistically significant(P <0. 05 ). The cost of LAH group was higher,and all symptoms were relieved after opreation. In LAH group,the average recovery time of the surgery to return to work time was(21 ± 7) d, but in AH group that was( 36 ± 8 ) d. The differences of recovery rime between two groups were statistically significantly ( P < 0.05). In two groups B-myoma were not found obvious by follow-up. Conclusion Different surgical patterns of hysterectomy had their distinctive advantages. The key point of a successful operation was to avoid complications of the operation.

Objective To observe the effects of different environmental intervention on the learning-memory ability and choline acetyltransferase (ChAT) expression around the infarct in rats with unilateral local cerebral infarction.Methods SD rats were subjected to electric coagulation of MCA and then were assigned randomly to ①control group(5 in each group housed in a standard cage),②learn training group(housed in a maze cage),③enriched environment group(housed in a enriched environment cage).24 days later,rats were trained by water maze,and then killed for immunohistochemistry staining.The expression of ChAT in peri-ischemic cortex was examined.Results The escape latency of rats in enriched environment was the shortest((26.9 ± 4.8)s),and the times striding over the platform was the most(6.1 ±1.1),longer (33.6 ± 5.1)s and less (4.8 ± 1.2)in the learn training group,the longest ((41.4 ± 6.4) s) and least (3.3 ± 0.9) in the control group.The positive cells of ChAT in enriched environment group (40.3 ± 8.4) were higher than those in learn training group (35.6 ± 7.8) and those in control group (25.4 ± 6.5).Conclusion Enriched environment after MCAO could promote the learning-memory ability and up-regulate the expression of ChAT in the peri-ischemic regions.
