Objecfive To explore pathological mechanism and treatment of central hyponatrem-ia. Methods Synchronous assay was made to detect changes of atrial natriuretic peptide(ANP),brain natriuretic peptide(BNP),endogenous digitalis-like substance(EDLS),antideuretic hormone (ADH),Na+ concentrations in blood and urine as well as osmotic pressure of plasma and urine in 68 pa-tients with traumatic brain injury(TBI). Results Of all,there were 27 patients with hyponatremia,mostly in patients with severe or critical TBI.There found syndrome of inappropriate secretion of antidi-uretic hormone(SIADH)in 7 patients and cerebral salt wasting syndrome(CSWS)in 20. Conclu-sions The central hyponatremia in patients with TBI may be related to the increased secretion of EDLS and ADH.The decrease of ANP and BNP in blood has no direct effect on Na+ concentration in blood.In-travenous injection of extrinsic thyrotropin releasing hormone(TRH)may inhibit dilutional hyponatremia resulted from increased secretion of ADH in TBI patients.

An alternative method based on an off-line solid phase extraction ( SPE ) combined with programmable temperature vaporizer-based ( PTV) large volume injection-gas chromatography-flame ionization detection ( LVI-GC-FID ) was developed. The goal of this study was to determine mineral oil saturated hydrocarbons ( MOSH ) in camellia seed oils. The purification condition of SPE columns with silver impregnated the activated silica gel and activated aluminum oxide was optimized. The optimal SPE cartridge was loaded with 10 g of Ag-activated silica gel per 10 g of activated aluminum oxide. The PTV initial temperature was set at 75℃ for 1 min (split 200:1), and heated from 75℃ to 370℃ at 250℃/min. Then the diverter valve was closed for 1 min and opened again with the split flow ratio changing to 50:1 . The injection volume was 40μL. The calibration curve of paraffin oil was liner in the range of 5-500 mg/kg with correlation coefficient of 0. 998. The detection limit (LOD) and the quantification limit (LOQ) of paraffin oils in hexane were 0. 26 mg/kg and 0. 80 mg/kg, respectively. The recoveries from spiked oil samples were between 93 . 3% and 112 . 7%, with relative standard deviation ( RSD ) of 1 . 8%-5 . 2%, the RSD of intra-day and inter-day were less than 2 . 6% . This procedure was applied to analyze the MOSH in 11 commercial camellia seed oils and the contamination was found to range from 6. 8 mg/kg to 76. 7 mg/kg. The method is simple in operation with high sensitivity, good reproducibility and low cost, and suitable for determination of MOSH in vegetable oils.

Objective The development of cancer vaccines deserves experimentation,specifically the immunogenicity of the new MUC1 DNA vaccine for pancreatic cancer.Methods Three strategies were combined to optimize the new MUC1 DNA vaccine.The female C57BL/6 mice were immunized,through tibial muscle injection,with 100 μg of plasmid DNA of the recombinant plasmids (pIRES2-EGFP-3VNTR group,pIRES2-EGFP-3VNTR-C1-144 group,pIRES2-EGFP 3VNTR-mIL-18 group,pIRES2-EGFP-3VNTR-C1-144-mIL-18 group,n=5) for a total volume of 100 μl.Mice inoculated with the empty vector pIRES2-EGFP (EV group,n=5) and normal saline (NS group,n=5) were used as vector and blank controls,respectively.All the mice were immunized again every two weeks.Two weeks after the third immunization,all the mice were euthanized and spleen cells were separated for CTL cytotoxic assay.Results The specific cytolysis percentages of the four groups (pIRES2-EG-FP-3VNTR,pIRES2-EGFP-3 VNTR-C1-144,pIRES2-EGFP-3VNTR-mIL-18,pIRES2-EGFP 3VNTR-C1-144-mIL-18) expressing VNTR were higher than the EV and NS group with the effector/target cells ratio (E/T) from 80:1 to 20:1 (P<0.05).Therefore,it showed a difference among the four groups.After the primary immunization,the OD450 of the serum antibody level specific to MUC1 began to increase in the four groups which contained the gene of VNTR3 (P<0.05).This suggests that the recombinant plasmids could induce a specific antibody response to MUC1,and showed no remarkable difference among the four groups.IFN-γ serum cytokine among the four groups were higher than that of the EV and NS groups (P<0.05).There was a significant difference of OD450 between the groups containing mIL-18 pIRES2-EGFP-3VNTR-mIL-18,pIRES2-EGFP-3VNTR-C1-144-mIL-18) and those not (pIRES2-EGFP-3VNTR,pIRES2-EGFP-3VNTR-C1-144,)(P<0.05).Conclusions In conclusion,all of the four recombinant plasmids could induce MUC1 specific CTL and antibodies responses,and C1-144 and IL-18 could enhance the immunogenicity of plasmids.
