Result: The high antibody titer (1:1600) of intramuscular injection of the mixture of microspheres and the plasmid DNA was obtained, similar to that of intramuscular injection of the mixture of AL(OH)3 and hepatitis B virus S antigen; while intramuscular injection the plasmid DNA elicited no serum antibody respones. Conclusion: biodegradable microspheres may be used as an good adjuvant for DNA immunization.

Fura—2 was used as a Ca~(2+) indicator to determine the intracellular calcium ion concentra-tion(〔Ca~(2+)〕i)of rat peritoneal macrophages(RPM?s),and APAAP enzyme immnoassay was ap-plied to detect the expression of Ia antigens on RPM?s.The results showed that norepinephrine(NE,10~(-9)mol/L)could markedly increase the〔Ca~(2+)〕i of the RPM?s(p

A series of novel 4-substituted-3-nitrobenzamide derivatives were designed and synthesized. The structures of the target compounds were confirmed with 1H NMR, 13C NMR, MS and element analysis. Anti-tumor activities against HCT-116, MDA-MB435 and HL-60 cell lines in vitro were evaluated by SRB assay. The results indicated most of the target compounds exhibited potent anti-tumor activity. Compound 4a showed the most potent inhibitory activities against three cancer cell lines with the GI50 values of 1.904-2.111 micromol x L(-1). Compounds 4g, 41-4n exhibited more potent inhibitory activities against MDA-MB435 and HL-60 cell lines with the GI50 values of 1.008-3.586 micromol x L(-1) and 1.993-3.778 micromol x L(-1), respectively. The structure-activity relationship of these compounds is discussed preliminarily.

Objective To explore changes of gray matter volume in patients with obsessivecompulsive disorder (OCD) in Chinese Han population using optimized voxel-based morphometry (VBM) ,and investigate its relationship with clinical symptoms. Methods Twenty patients with OCD and 20 age,sex and handedness matched healthy controls were scanned using 3D-T1 images on a 3.0 T MR system. The high resolution T1WI was preprocessed according to the optimized VBM protocol in Statistical Parametric Mapping (SPM5). Two-sample t test was performed to characterize the differences of the gray matter volume (GMV) between the OCD patients and healthy controls, and the correlations between the GMV and symptom severity and cumulative illness duration were examined using Pearson correlation in SPSS 16. 0, respectively.Results Compared to controls, OCD patients demonstrated increased GMV in left thalamus, right thalamus and left cerebellum after false discovery rate (FDR) correction. No areas of significantly decreased GMV was observed in OCD patients in relative to healthy controls. The mean eigenvalue ranged from 0. 5782 to 0. 889 representing the left thalamus volume of OCD patients was 0. 6813 ± 0. 0718, and that ranged from 0. 5546 to 0. 9062 was 0. 6869 ± 0. 0808 tor right thalamus. The mean eigenvalues were positively correlated in bilateral thalamus (r = 0. 94, P ＜ 0. 01). Conclusion Using optimized VBM, the current research indicates that the pathophysiology of OCD is associated with GMV abnormalities not only in corticostriato-thalamo-cortical (CSTC) circuit, but also in the cerebellum.

Objective To investigate the hemodynamics of increasing portal venous pressure(PVP) in hepatocellular carcinoma patients complicated with hepatic arterioportal vein fistulas (HAPVF)and the diagnosis and therapy of intractable upper gastrointestinal hemorrhage caused by HAPVF.Methods One hundred and fifteen cases of hepatocellular carcinoma with upper gastrointestinal hemorrhage were checked by hepatic arteriography and were treated through orifices embolization in cases with severe HAPCF by coils and/or ethanol. Results Twenty-six out of 31 patients suffering intractable upper gastrointestinal hemorrhage have severe HAPVF(the main stem of portal veins are visible).However,there are only 15 patients with light HAPVF among the 84 patients who have mild upper gastrointestinal hemorrhage (the main stem of portal veins are invisible).After the embolization,all of the 26 patients who have severe HAPVF stopped bleeding.Among them,the main stem of hepatic arteries are occluded in 2 patients. Conclusion The existence of severe HAPVF should be taken into consideration when intractable upper gastrointestinal hemorrhage occurs in hepatocellular carcinoma patients,and it can be diagnosed through hepatic artery DSA.Orifice embolization is the most effective method for such kind of hemorrhage.

Objective To investigate the effect of α-tocopherol on fibrosis of chronic pancreatitis (CP) rat and explore its mechanism.MethodsMale Wistar rats were randomly divided into control group,acute necrotizing pancreatitis (ANP) group,α-tocopherol group.CP was induced by dibutyltindich loride ( 8 mg/kg) infusion into the tail vein.Gastric lavage of α-tocopherol (800 mg/kg body weight,daily) was started 24 hours after dibutyhindich loride infusion for 4 weeks.The rats in ANP and control group received 0.6 ml salad oil gastric lavage.The rats were sacrificed 4 weeks later.Pancreatic tissue was harvested for histological examination and collagen staining,and measurement of the levels of hydroxyproline and malondialdehyde (MDA) of the pancreas were performed.The mRNA expression of transforming growth factor (TGF)-β１ was measured by real time PCR.ResultsAfter gastric lavage for 4 weeks,the pancreatic tissue inflammation,fiber deposition and abnormal structure in rats of α-tocopherol group were greatly reduced.The levels of MDA and hydroxyproline in rats of α-tocopherol group were significantly lower than those in ANP group [ (0.40 ±0.20) vs (1.07 ±0.41) nmol/100mg,(402.49 ±27.62) vs (664.92 ±29.04) μg/g,P＜0.05].The expressions of TGF-β1 mRNA in rats of o-tocopherol group were significantly lower than those in ANP group (2.24 ± 0.89 vs 3.35 ± 0.66,P ＜ 0.05 ).Conclusions Tocopherol gamma can improve pancreatic inflammation and fibrosis by reducing the oxidative stress level and down-regulating the expression of TGFβ1mRNA in rats with CP.
