Legal clinic education originating in the United States, aims at educating students on legal practical skills, and plays an positive role in cultivating students' ability of integrating theory with practice and training their various practical vocational skills. The present Chinese training mode of health law specialty does not perform very well in training students' practical ability, while legal clinic education can better make up for some deficiencies. Therefore, this paper learns from the experience of American universities in their legal clinic education, such as the particular division of specialties, the development of outside-school clinics, taking pre-training seriously, and the unique evaluation mechanism. Correspondingly, we explore to construct a set of reasonable legal clinic education system in health law specialty, including the orientation of legal clinics, the double training system inside and outside school, the construction of teaching staff and the establishment of evaluation mechanism.

BACKGROUND:Polylactic acid(PLA)surface is hydrophobic and there are no nataral recognition sites,so its application is limited.Many different strategies have been studied such as composition and chemical Drafting,to produce hydrophilic groups.However,these traditional methods are always involved in complex process and many organic reagents,resulting in decrease of biocompatibility.OBJECTIVE:To conduct the surfacr modification of PL.A and improve its hydrophilicity with low temperature plasma treatment.DESIGN:Controlled observation.SETTING:Department of Materials Science and Engineering in Jinan University.MATERIAIS:The experiment was processed from October 2004 to October 2005 at Guangzhou Research Center of Artificial Organs and Materials Engineering(Ministry of Education).The mainly used materials were:Poly-D,L-lactic acid(Mr 2.9×104,Shandong Medical Instrument Institute),N-vinyl-pyrrolidone(NVP,Acros Company,purified before use).METHODS:The materials were treated in the plasma reactor under different conditions(power=150 W,t=3,2,1 minutes;power=30 W,t=10,8,5,3,1 minutes)to choose the optimal condition,and then PLA were grafted with NVP by gas phase polymerization and liquid polymerization,respectively.MAIN OUTCOME MEASURES:THe surface morphology of the films was observed with scanning electron microscopy and atomic force microscopy.The hydrophilicity of native and treated material surfaces was measured using a water contact angle meter.Surface composition was detected with Fourier transform infrared spectrometer.Mass changesmeasurement was applied to characterize the grafting efficiency.RESULTS:Scanning electron microscopy and atomic force microscopy showed that the plasma medified materials possessed coarse surface with pores and notches.Water contact angles decreased obviously from 78°to 50°after grafting,Fourier transform infrared spectrometer showed a new absorption peak at 1 637.19 cm-1,which corresponded to the carbonyl stretch vibration absorption of amide group in poly-N-vinyl-pyrrolidone.After the plasma treatmerlt at low temperature.the mass change ratio of PLA film material was-0.6.CONCLUSION:The plasma treatment and polymerization can improve the hydrophilicity and cause coarsr surface of PLA material,which will be helpful for the cell attachment.

Objective To investigate the role of protein phosphorylation in Pseudomonas aeruginosa (P.aeruginosa) strains in response to stress triggered by mouse macrophages.Methods The strong cation exchange-immobilized metal affinity chromatography (SCX-IMAC) was performed to enrich phosphopeptides.The nanoscale liquid chromatography coupled to tandem mass spectrometry (nano LC-MS/MS) was carried out to identify and analyze phosphoproteome.Results Fourteen phosphopeptides from twelve proteins were identified within thirty-one phosphorylation sites on serine,threonine and tyrosine residues.Fifty percent of these phosphorylated proteins were membrane proteins,indicating that their phosphorylation modification was more critical for bacteria in response to the stress.In terms of biological process of Gene Ontology,these identified proteins were involved in stress response,iron transport,anaerobic respiration,response to hydrogen peroxide and signal transduction by phosphorylation,etc.Conclusion These phosphorylated proteins in P.aeruginosa strains are necessary for signal transduction and their response to harsh environment within the macrophages,such as iron limitation,hypoxia and oxidative stress.This study provides evidence for further investigation on virulence and pathogenesis of P.aeruginosa.

Objective To explore the feasibility of virtual touch tissue quantification(VTQ) technique in noninvasive assessment of transjugular intrahepatic portosystemic stent shunt (TIPSS).Methods Twenty-four patients were enrolled in this study.Shear wave velocity(SWV) of the liver and spleen were obtained by VTQ technique on one day before TIPSS insertion and one week after TIPSS placement,and the portal vein pressure was measured while placing the TIPSS.The correlation between SWV of the liver and spleen and portal venous pressure were analysed.In addition,fourteen patients were followed up for one month after TIPSS placement.Results There was significant difference in portal vein pressure pre [(27.82 ± 4.07) mm Hg] and post [(16.26-± 3.10) mm Hg] TIPSS insertion.The SWV of the liver in patients pre and post TIPSS measured (2.43 ± 0.37)m/s and (2.40 ± 0.34)m/s,respectively.The SWV of the spleen in patients pre and post TIPSS were (3.49 ± 0.40)m/s and (3.08 ± 0.39)m/s,respectively,there was significant difference (P =0.000).However,SWV of the liver pre and post TIPSS placement was no significant difference(P =0.130).And as well as the patients which were followed up for one month after TIPSS placement.A significant,direct,linear correlation(r =0.602,P =0.000) was found between SWV of the spleen and portal vein pressure,but liver SWV was not correlated with the portal venous pressure.Conclusions SWV of the spleen measured by VTQ technique has a significant correlation with portal vein pressure.Hence,the spleen SWV based on VTQ technique can be used as a non-invasive method for quantitatively in monitoring the portal vein pressure as the function of the TIPSS.However,evidence to support a similar role for liver stiffness is lacking.

Objective To investigate the effect of IH764-3 on the leukocyte-mediated hypoxia-reoxygention injury of human brain microvascular endothelial cell (HBMVEC). Methods MTT assay was used to detect the survival of HBMVEC; gelatin zymography was used to check the activity of MMPs. The level of reactive oxygen species (ROS) in leukocyte was determined via commercially available kit,and the indirect enzyme-linked immunosorbent assay (ELISA) was used to quantify the contents of TNF-?,IL-1?,IL-2 and INF-? in leukocyte culture medium.Results Survival of HBMVEC was impaired by hypoxia-reoxygenation,which was aggravated by supernatant of activated leukocytes but was attenuated by IH764-3. Leukocytes produced high level of MMP-9,ROS and cytokines (TNF-?,IL-1?,IL-2,IFN-?) after hypoxia-reoxygenation,the process was inhibited by IH 764-3. Furthermore,IH764-3 could effectively reverse hypoxia-reoxygenation injury of HBMVEC with supernatant of activated leukocytes. Conclusion IH764-3 can protect HBMVEC from leukocyte-involved hypoxia-reoxygenation injury by attenuating the activation of leukocytes and inhibiting the pathogenic effects of leukocytes products.
