AIM To observe the effects of rhIL 10 on psoriatic models and immune function in mice. METHODS The anti psoriatic effect of rhIL 10 was studied by using the models of vaginal epithelium and tail scales of mouse. ConA induced proliferation and production of IL 2 and IFN ? by T lymphocytes, LPS induced production of IL 1 and TNF ? by the peritoneal macrophages and the activity of NK cells, LPS induced proliferation of B lymphocyte were determined. RESULTS The result showed that rhIL 10 (5, 20 and 80 ?g?kg -1 ?d -1 ,sc) could significantly inhibit the mitosis of vaginal epithelial cells in mice treated with estrogen. No abnormal changes of nucleolus and organelle were found under electronic microscope. rhIL 10 facilitates development of granular cell layers in mice tail scales. There were for 2 to 3 granular cell layers and bigger granular cells in scales under electronic microscope. CONCLUSION The anti psoriatic effect of rhIL 10 is related to inhibiting hyperplasia of epidermal cells and promoting the formation of granular cells and possessing anti inflammatory and immunomodulatory activity.

Diffusion tensor imaging(DTI) is an efficient and noninvasive tool to investigate the characteristics and functions of white matter fiber tracts,and it can be used to study the relationship between the structure and function in the nervous system,the plasticity and damage repair of visual development,abnormalities of the white matters that relate to the visual pathways.Recently,the quantification of white matter fiber tracts from the lateral geniculate bodies to the occipital lobe visual cortex using DTI offers morphological information for the function and structure of the white matters during visual development.Some studies attempt to compare the DTI outcomes and tractography between amblyopic children and normal children so as to better display the variations of optic radiation in children with amblyopia,and to evaluate the relationship between structure and function of the white matters.DTI becomes an important supplementary research approach in these fields.This paper reviews the application of DTI in visual development and amblyopic eyes.

Method ELISA was used to test cord blood EPO and ET-1 in 54 high risk neonates as subjects and 14 healthy neonates as controls.Results The cord blood EPO levels in amniotic fluids turbid Ⅲ degree group and group eclampsia/pre - eclampsia were higher than those in control group (t= 4.0842,3 680 allP

BACKGROUND: Property of artificial liver reactor is generally evaluated by using an enclosed experimental device, which is constructed through simulating bioartificial liver supporting system. Moreover, the enclosed experimental device is also comprehensively evaluated biological function of hepatocytes and biological response efficiency. In addition, it is significance for primarily evaluating the properties of polysulfone membrane hollow fiber reactor to optimize bioartificial liver supporting system. OBJECTIVE: To construct polysulfone membrane bioreactor experimental system, understand the effects on plasma of patients with severe hepatitis, and observe the feasibility of hollow fiber reactor regarded as bioartificial liver reactor. DESIGN: Repeated measurement.SETTING: General Infectious Disease Institute, Southwest Hospital, the Third Military Medical University of Chinese PLA. MATERIALS: Seven Chinese mini-pigs with 1-7 days old and of either gender were provided by Experimental Animal Center, the Third Military Medical University (certification: F99017). The animal disposal accorded to the ethical standard. Tumor necrosis factor-α (TNF-α) and transforming growth factor-β1 (TGF-β1) kits were purchased from Jingmei Bioengineering Company, China; polysulfone membrane hollow fiber reactor by Shanghai Dehong Biomaterial Institute, China; Cellco culture-circular artificial capillary culture system by Spectrum Company, USA; seven plasma exponents were taken from admission patients with chronic severe hepatitis during plasma exchange. All patients provided the informed consent, and the animal experiment was conducted with confirmed consent by the local ethics committee.METHODS: This study was performed at the General Infectious Disease Institute, Southwest Hospital, the Third Military Medical University of Chinese PLA from January 2004 to July 2005. ① Experimental procedure: The experimental pigs underwent ablactation at 12 hours before experiment, and then hepatocytes were separated after cleaning their fur. An enclosed system was composed of polysulfone membrane hollow fiber reactor and Cellco culture-circular artificial capillary culture system, which were connected with oxygen-carbon dioxide diffusion tube and media holding pond. Interface of external cavity was blocked with clean rubber tampon. The separated hepatocytes underwent spheroid culture by using magnetic stirring method, and then they were inoculated in the external cavity of polysulfone membrane hollow fiber reactor. Next, 200 mL plasma from severe hepatitis patients was added in media holding pond and circled from internal cavity of reactor to media holding pond at the speed of 80 mL/min. ② Experimental evaluation: 2 mL liquid circulation separately collected from internal cavity of reactor at 0, 2, 4 and 6 hours after circulation was used to measure level of ammonia in supernatant by using glutamic dehydrogenase-violet method. In addition, content of total bilirubin was detected by using automatic biochemistry analyzer, prothrombin time by using automatic blood coagulometer, and TNF-α and TGF-β1 were detected according to the kits. MAIN OUTCOME MEASURES: Effects of polysulfone membrane bioreactor on ammonia, bilirubin, prothrombin time, TNF-α and TGF-β1 in plasma of patients with severe hepatitis.RESULTS: ① Measurement of ammonia, total bilirubin and prothrombin time in patients with severe hepatitis: Level of ammonia decreased persistently, in particularly, the decrease was obvious from 0 to 2 hours, and then, it was decreased slowly. While, level of total bilirubin was also decreased persistently, and it was significantly lower at 6 hours than that at 0 hour (P < 0.05). Moreover, prothrombin time was decreased persistently, and it was significantly lower at 6 hours than that at 0 hour (P < 0.05). ② Measurement of TNF-α and TGF-β1 in patients with severe hepatitis: Contents of both TNF-α and TGF-β1 decreased persistently, and they were significantly lower at 6 hours than those at 0 hour (P < 0.05). CONCLUSION:Polysulfone membrane bioreactor experimental system can clear noxious substance of small molecules in plasma of patients with severe hepatitis, supply beneficial components, and decrease levels of cytokines. Therefore, it can be regarded as the bioartificial liver reactor.

Objective To research the applications of resting-state functional MRI in conjunction with voxel-based morphometry on cerebral functions and structures in patients with schizophrenia. Methods Thirty-two patients with schizophrenia and 32 healthy people underwent resting state functional magnetic resonance imaging (Rs-fMRI)and sagittal scanning T1WI with 3D FFE Pulse Sequence. Rest1.8 software was applied to calculate the differences of amplitude of standardized low-frequency fluctuation(ALFF)between the two groups,then the voxel-based morphometry(VBM)data of abnormal brain regions were evaluated to compare the differences of grey matter intensity. Finally,combining with ALEF and VBM,we explored the changes of cerebral functions and structures. Results As compared to the control group ,the ALFF-elevated regions were the right putamen ,the left orbital frontal cortex extending to the left putamen and left dorsal-lateral superior frontal gyrus;the ALFF-decreased regions were the right inferior tempotalgyrus,the left posterior cingulated gyrus and the left angular gyrus(P<0.05). No elevated regions of grey matter intensity were found in the patient group. Conclusions Extensive abnormal active regions of the brain under resting state could be found in patients with schizophrenia ,the grey matter intensity of abnormal regions also decreased generally. They are in accordance with the glutamate-hypothesis of schizophrenia ,which involves extensive impairments of neurons ,disorders of neurotransmitter′s circulations and balances.
