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).

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.

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.

The effects of high concentrations (1-5mmol/L) of different amino acids in Hanks solution on the proliferation of Ehrlich ascites tumor cells and Walker 256 carcinosarcoma cells were examined. In order to demonstrate the inhibitory effect of some amino acids at high concentration level, the further studies were conducted on Ehrlich ascites tumor cells, human hepatoma cells and lung cancer cells, using Eagle's MEM as culture medium. The possible toxicity of the high concentrations of single amino acids to normal tissue cells was tested on mouse bone marrow cells. Although some amino acids exhibited a significant inhibitory effect, the responses of different tumor cells to the high concentrations of different amino acids were not entirely similar. Moreover, the effects presented by some amino acids on Ehrlich ascites tumor cells in Hanks solution could be diminished or eliminated in Eagle's MEM. Among the aromatic and basic amino acids, only the tryptophan was found to be inhibitory to the multiplication of mouse bone marrow cells at high concentration levels in vitro.
