Twenty eight patients with multiple organ dysfunction syndrome (MODS) underwent continuous venovenous hemofiltration (CVVH)in ICU from June 2003 to June 2008, including 13 cases treated with predilution mode and 15 with postdilution mode. The changes of oxygenate index( PaO2/FiO2 )during CVVH were retrospectively analyzed. The total case fatality rate of this group of patients was 46%(13/28). There was a significant increase in PaO2/FiO2 of 28 cases during the first 48 h of CVVH (P ＜0. 05);the levels of PaO2/FiO2 in predilution group had increased significantly within 48 h during CVVH (P＜0. 05), while those in postdilution group had not significantly changed (P ＞ 0. 05). There was a significant increase in Pa02/FiO2 for the survival patients during the first 48h CVVH( P ＜ 0. 05 ), while no significantly change in the fatal cases(P ＞0. 05 ). In summary, oxygenate function and outcome of patients with MODS can be improved by CVVH, and predilution may be a more effective mode.

Objective To detect the genetic association between schizophrenia and polymorphism of phosphodiesterase 4B (PDE4B) gene. Methods Observed in a sample of 98 parent/offspring trios where the proband net the Amerecan Classification and diagnostic Criteria for Mental Disorders The Forth Revised Edition,criteria for schizophrenia using correlation analysis and haplotype relative risk analysis. The polymorphism of phosphodiesterase 4B gene was detected with PCR methods and SNP typing in all nucleus families. Results The rs2180335 al-lele was connected with schizophrenia (P = 0.02131). Allele A was protective factor (Z = -2. 184) and allele G was the hazard factor (Z = 2.184). The frequency of rs2180335 allele A was 0.452 and the allele G was 0.548. The rs1040716, rs 3767311 and rs472952 allele was independence with schizophrenia. Five kinds haplotypes of A/A in the rs2180335-rs3767311, A/A in the rs 3767311-rs472952, A/A/A in the rs2180335-rs3767311-rs472952,A/G/G/A and T/A/A/A in the rs1040716-rs2180335-rs3767311-rs472952 associated with schizophrenia (P values were 0. 028715,0. 034845,0. 024177,0. 023967,0. 010839,genotype frequencies were 0. 223, 0.223,0.127,0.081,0.073). Conclusion It shows an association between schizophrenia and the rs2180335 polymorphism at nucleotide of phosphodiesterase 4B gene in Chinese.

ObjectiveTo detect the association between schizophrenia and polymorphism of phosphoserine aminotransferase 1 ( PSAT1 ) gene.MethodsThe study group included 158 patients with schizophrenia from Xi' an Mental Health Center and the control group included 316 parents.The polymorphism of rs69287125,rs137824326 of phosphoserine aminotransferase 1 gene was detected with PCR methods and SNP typing in all nucleus families by correlation analysis and haplotype relative risk analysis.ResultsThe rs69287125 allele was associated with schizophrenia (P=0.011 ),the G allele was protective factor (Z =-2.31 ) and the A allele was hazarding factor (Z =2.31 ).The rs137824326 allele was associated with schizophrenia (P=0.007 ),the G allele was protective factor ( Z =- 2.54) and the A allele was the hazarding factor( Z =2.54).The haplotypes of A/A and G/G in the rs69287125-rs137824326 were associated with schizophrenia (P =0.021,0.015,Z =2.16,- 1.85).ConclusionThe polymorphism of phosphoserine aminotransferase 1 gene is associated with schizophrenia in Chinese.

Objectives:In this study,the effects of glutamine(Gln) and branched chain amino acids(BCAA) enriched formulas on free radical metabolism and immunity in traumatized rats were investigated. Methods:After injury,twenty one male Wistar rats were randomly divided into three groups,and fed with rations containing casein,a commercial amino acids(17AA),and a new amino acids formula(20 AA) respectively.The rations were isonitrogenous and isocaloric.Before operation and on days 3,7,14 postoperation,body weight,dietary intake,the concentrations of MDA,the activities of SOD in plasma were measured.At last,the animals were killed,the hydroyproline and spleen lymphocyte blastogenesis were determined. Results:①After injury,body weight of rats were reduced significantly,the concentrations of MDA in plasma were increased,while the SOD activities were decreased. ②Compared with 17AA group, the levels of hydroyproline in sponge were increased in 20AA group.③There were better effects of reducing plasma MDA levels and enhancing plasma antioxidase activities in 20 AA group than 17 AA group.④The weight of thymus and spleen and spleen lymphocyte blastogenesis were more obviously increased in 20AA group than in 17AA group. Conclusions:The new amino acids preparations can increase the antioxidase activities,enhance immunity and promote wound healing.

Objective To observe the correlation of histologicalactivity(HAI) of chronic hepatitis B (CHB) with CCL20 expression, and to investigate the impact of CCL20 expression in CHB infection. Methods On the basis of established competitive quantitative RT-PCR with an internal standard, the expression of the CCL20 in the hepatocytes in different infected patterns of HBV infected cells and liver biopsies were quantified and at the same time its correlation to HAI were explored. Results In the cell levels, the expression quantity of CCL20 in control cells (HepG2), persistent HBV infected hepatocytes( HepG2. 2. 15) are (2. 65 ± 0. 02) pg/106 cells, ( 1.22± 0. 04) pg/106 cells, respectively. There were significantly differences between them ( t = 39. 66, P < 0. 01 ). The expression of CCL20 was enhanced in hepatocytes stimulated by PMA but their expression pauern was not changed. Moreover, CCL20 expression in liver biopsies with CHB was (3.54 ± 0. 65 ) pg/20 mg and CCL20 expression in control groups was ( 8. 74±0. 56) pg/20 mg. The expression of CCL20 between two groups was different (t =30. 09,P <0. 01 ) and correlation lied in between HAI and CCL20 expression in liver biopsies of CHB patients ( r = 0. 675, P =0. 023 ). Conclusion CCL20 expression was down-regulated and it was correlated to HAI of liver biopsies in CHB patients.
