AIM: To study the renoprotective and synergistic effects of sesamin in combination with vitamin E on nephropathy in rats with the metabolic syndrome.METHODS: Nephropathy of metabolic syndrome in rats was induced by high-fat and high-carbohydrate diet.Sesamin(30 mg?kg-1?d-1),sesamin +vitamin E [(15+20) mg?kg-1?d-1),sesamin +vitamin E(30+20) mg?kg-1?d-1] and vitamin E(20 mg?kg-1?d-1) were given to rats with metabolic syndrome at 9th week and lasted for 16 weeks.After 24 weeks,the body weight,left kidney humid weight,blood glucose(BG),blood lipids(BL),systolic blood pressure(SBP), renal function,and indexes of oxygenation and antioxygenation for renal cortex were measured.Pathological changes,collagen deposition and iNOS protein and nitrotyrosine expression of kidney were observed by HE-stain,Masson-stain and immunohistochemical method,respectively.RESULTS:(1)In high-fat and refined-sugar diet group(HFS): the levels of BG,BL,SBP,and MDA,OH and NO2-/NO3-in renal cortex were increased;the activities of T-SOD, CAT and GSH-Px in renal cortex were decreased;the expressions of iNOS protein and nitrotyrosine in kidney were up-regulated;the inflammatory cell infiltration and collagen deposition in renal glomerulus and renal interstitium were severe;the glomerular sclerosis and renal interstitial fibrosis were obvious;the renal function was deteriorated.(2)In sesamin +vitamin E [(30+20) mg?kg-1?d-1] group: the decreases in BG,BL,SBP,MDA,OH-and NO2/NO3-in renal cortex were obviously observed;the activities of T-SOD,CAT and GSH-Px in renal cortex were increased;the expressions of iNOS protein and nitrotyrosine in kidney were down-regulated;the inflammatory cell infiltration and collagen deposition in renal glomerulus and renal interstitium were improved;the glomerular sclerosis and renal interstitial fibrosis were reversed;the renal function was ameliorated.The therapeutic effect of sesamin +vitamin E[ (30+20) mg?kg-1?d-1] surpassed that of using sesamin or vitamin E alone(P

BACKGROUND: Demineralized bone matrix and bone morphogenetic protein have been shown to have good bone induction, but less studies concerned nanometer demineralized bone matrix. Its physical and chemical properties and biological security are not yet clear.
OBJECTIVE:On the basis of preparing the nanometer human demineralized bone matrix in previous experiment, we mixed the recombinant human bone morphogenetic protein-2 together to obtain the new bone graft substitute and to research its physical and chemical properties and biological security.
METHODS:The human demineralized bone matrixes were prepared by the method of modified Urist and nano-processed then mixed with the bone morphogenetic protein-2 in specific proportions in order to be lyophilized to complete the fol owing experiments. (1) Pyrogen experiment:the material extracts were injected in the rabbits by ear intravenous. (2) Toxicity experiments:material extracts and saline were separately injected via the tail vein of mice in vivo. (3) Implantation experiments:experimental materials andβ-tricalcium phosphate were implanted into rabbits on both sides of the hindlimb muscle.
RESULTS AND CONCLUSION:After lyophilized shaping, the nanometer demineralized bone matrix material had dense surface and it’s pore diameter was 100-400μm. The pore distribution was less uniform and the porosity was of less than 30%. The main elements were carbon, oxygen and nitrogen. Nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 did not have pyrogen effect and the rabbits’ body temperature had no significant fluctuations after injection. The acute systemic toxicity test results showed that the nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 complied with the relevant provisions of the State, without obvious toxic reaction. The inflammatory response of nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 was significantly lighter than the reaction ofβ-tricalcium phosphate. The results showed that the nanometer human demineralized bone matrix with recombinant human bone morphogenetic protein-2 is a nanometer al ogeneic bone graft substitutes with nontoxicity, good biocompatibility, high bioavailability, and less inflammatory reaction.

Objective:To study the possible immune escape mechanisms of HCoV-OC43 from human dendritic cells(DC).Methods:HCoV-OC43 was isolated from clinical specimen using BSC-1 cells and identified by Real-time PCR,and the cytopathic effect was observed by phase contrast microscope.DCs were induced in vivo using hu-GM-CSF and IL-4 cytokines,and after 7 days of differentiation,DCs were infected by HCoV-OC43.The morphology of HCoV-OC43 infected DC was observed by transmission electron microscope,and the cytokines related to DC functions were detected by Real-time PCR after infection.DC proportion and function related co-stimulatory molecules were analyzed by flow cytometry.Results:In vitro HCoV-OC43 infected human DC model was successfully built.HCoV-OC43 can infect DC and generate immune response of DC in vitro,but no virus nucleonic acid could be detected in culture supernatant.The DC expression of IFN-α,IFN-β,CCL3 and CCL5 were significant decreased when infected with HCoV-OC43,but the expression of costimulatory molecules including HLA-DR,CD1c and CD86 were not affected by HCoV-OC43 infection.Conclusion:Human DC could be infected by HCoV-OC43 and generate immune response,but could not produce progeny virus.HCoV-OC43 may escape from immune response by suppressing the expression of IFN-α and other inflammatory cytokines and chemokines in DC.

Objective To investigate the effects of radix salviae militiorrhizae (RSM) on acute lung injury induced by"two hits"and to study its probable mechanism.Method Thirty Wister rats were randomly divided into three groups:namely normal control group,model group and RSM treatment group.The model was created by"two-hits"in which 0.2 ml/kg oleic acid was injected into tail vein first,and then 2 mg/kg lipopolysaccharide was administered four hours later.After model rats sacrificed,the pathological changes of lung were observed,and lung wet/dry weight ratio,protein content,and the ratio of neutrophiles in brochoalveolar lavage fluid (BALF) were calculated.In addition,the expression of Fas,FasL protein and apoptosis were evaluated by immunohistochemical studies and TUNEL technique.Results The acute lung injury rat model was successfully induced by"two hits".The gross and micrographic injury of lung was milder in RSM treatment rats than in model rats.The W/D ratio,protein contents and the ratio of neutrophiles in BALF were also markedly reduced in comparison with model rats,while the expression of Fas and Fasl,and the apoptosis index in model rats were significantly increased compared with other two groups.Furthermore,it showed a positive correlation between the expression of Fas,FasL,and the number of cell with apoptosis.Conclusions RSM shows a protective effect on ALT rats caused by"two hits"likely reaulted from inhibiting the expressions of Fas and Fasl,which are associated with the cell apoptosis of lung tissue.

Objective: To analyze the therapeutic effect of repeated hepatectomy on recurrent hepatocellu-lar carcinoma and prognostic factors. Methods: We retrospectively analyzed the clinicopathologic data of 48 patients who underwent repeated hepatectomy for recurrent hepatocellular carcinoma between July 1995 and July 2003. Overall survival rate and disease-free survival (DFS) rate were calculated by Kaplan-Meier meth-od. Prognostic factors were analyzed by univariate and multivariate analysis. Results: The median survival of 48 patients was 36.4 months. The overall 1-, 3-, and 5-year survival rates were 81.3%, 45.8%, and 27.1%, re-spectively. The disease-free 1-, 3-, and 5-year survival rates were 70.8%, 25.0%, and 16.7%, respectively. Univariate analysis showed that TNM stage of primary tumor, TNM stage of the recurrent tumor, vascular in-vasion, recurrent tumor size (>5cm) and recurrence-free interval were prognostic risk factors for overall surviv-al. While TNM stage of primary tumor, recurrent tumor size (>5cm), TNM stage of recurrent tumor, vascular in-vasion, pathological grading of recurrent tumor, preoperative AFP and recurrence-free interval were prognos-tic risk factors for DFS. Multivariate analysis showed that recurrence-free interval and TNM stage of recurrent tumor were independent prognostic risk factors for overall survival. While recurrence-frae interval and recur-rent tumor size (>5cm) were independent prognostic risk factors for DFS. Conclusion: Short recurrence-free in-terval (≤24 months), recurrent tumor size (>5cm) and TNM stage of recurrent tumor indicate poor prognosis of patients who received repeated hepatectomy for recurrent hepatocellular carcinoma.
