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.

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.

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.

Methods: The cognitive features of text anxiety were explored by exploratory factor analysis and confirmatory factor analysis on the basis of interview,questionnaire surveying and criterion.Results:There were 6 cognitive factors leading to test anxiety: self-test, worrying, magnifying conclusion, resistance, preparing, self-efficacy.Conclusion: The 6 factors of cognition about text are related to text anxiety

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

BACKGROUND: Understanding of patch classification, characteristics, and reaction with host is necessary for best selection of reparative surgery materials.OBJECTIVE: To summarize the patch classification, characteristics and its application in pelvic reconstruction, as well as the complications.METHODS: A computer-based online search of PubMed database (http://www.ncbi.nlm.nih.gov/PubMed) and CNKI database (www.cnki.net/index.htm) was performed for related articles with the key words "patch, polypropylene, compound patch" in Chinese and "reconstructive pelvic surgery, repair, replacement" in English. Articles regarding patch classification, characteristics biocompatibility, and application effect, or in the same circle published recently in authoritative journals were included. A total of 24 articles were finally selected.RESULTS AND CONCLUSION: Polypropylene patch is weaved network, with large mesh, which allows for fiber tissue ingrowth and improves tissue intensity and tensile strength. Leukocyte and macrophage can enter the mesh, so the patch has good anti-infection ability. Expanded polytetrafluoroethylene is soft and smooth, with good tissue tolerance, and can prevent affixion with intraabdominal tissues. Moreover, the submicron pore diameter prevents bacteria invasion. The inflammation and foreign body reaction induced by the expanded polytetrafluoroethylene is the most slight among artificial synthetic materials.

Objective To explore the effects of dl-3-n-butylphthalide on learning-memory ability and Na+-K+-ATPase activity of mitochondria in rats with chronic cerebral hypoperfusion.Methods Sprague-Dawlay rats were randomly divided into sham group( n= 10) ,model group (Permanent occlusion of bilateral common cawater maze test.Na+-K+-ATPase activity in mitochondria of forebrain tissue were also measured.Results Compared with sham group, memory ability of rats in model group decreased obviously( ( 10.41 ± 3.81 ), ( 25.54 prot- 1 , p ＜0.05 ).The memory ability of rats in large/small dose dl-3-n-butylphthalide groups both increased notably compared with the model group( respectively( 11.72 ± 5.78 ) s and ( 12.48 ± 5.45 ) s, P ＜ 0.01 ) and Na + -0.05 ).The effectives of large dose dl-3-n-butylphthalide and that of small dose dl-3-n-butylphthalide have no significantly differences.Conclusion Dl-3-n-butylphthalide could increase the Na + -K +-ATPase activity and protect mitochondria, improve the learning-memory ability of rats with chronic cerebral hypoperfusion.

Cytokine induced killer (CIK)cells are immune effector cells generated from mononuclear cells induced by many cytokines.CIK cells have several advantages, such as rapid proliferation, broad spectrum killing activity, high tumoricidal activity and non-major histocompatibility complex restriction.Recently, cord blood derived CIK cells have attracted extensive concerns because of its faster proliferation, higher tumoricidal activity and lower incidence of GVHD compared with adult peripheral blood derived CIK cells. This paper will review the biological characteristics, clinical application and research advances of cord blood derived CIK cells.
