Objective To investigate the nutrition support during stress response period after tumor ex-tirpation in middle-aged and elderly patients with oral and maxillofacial tumors. Methods Sixty patients who had undergone maxillofacial tumor extirpation were randomly divided into nutrition therapy group (n = 35) and control group ( n = 25 ). Patients in nutrition therapy group received enteral nutritional treatment, while patients in control group fed themselves. The nutritional status of the two groups before operations were evaluated with Concise Nutritional Assessment Indicators of human body measurement and biochemistry were used to evaluate the nutritional conditions. The incidence of post-operational complications and recovery time ( from the operation to discharge) were analyzed. Results The weight and arm muscle circumference in the nutrition therapy group significantly decreased after operations (P <0. 05). However, in the control group, all the nutritional indica-tors except the total lymphocyte count were significantly lower than the baseline levels after operations (P < 0. 05 ) ; particularly, of the average body weight decreased by about 6 kg. The incidence of complications in the nutrition therapy group was significantly lower than that in control group (5. 7% vs. 12. 0% , P <0. 05). The recovery time was significantly longer in the control group than that in the nutrition therapy group [ (28. 62± 2.38) vs. (22. 76± 3. 24) d, P < 0. 01 ]. Conclusion The nutritional support during the stress response period can satisfy the demands of high catabolism after maxillofacial tumor extirpation operation in middle-aged and elderly patients.

OBJECTIVE:To probe into the status quo and the developmental trend of oral hypoglycemic agents used in our hospital.METHODS:Using the defined daily dose as the study unit to make statistic analysis of oral hypoglycemic agents used in our hospital during 2004～2006 in respect of DDDs,consumption sum and average daily cost etc.RESULTS:Both the categories and consumption quantity of oral hypoglycemic agents increased year by year while the proportion of consumption sum was descending.Over the 3 years,dominating the first 5 places on the list of DDDs were glipizide,metformin,gliquidone,gliclazide and glibenclamide,respectively.CONCLUSION:The clinical use of oral hypoglycemic agents was basically reasonable in our hospital.

OBJECTIVETo observe the effect of the postpone in skeletal muscle aging process of D-galactose rats by weight training and soy polypeptide supplement in 6 weeks, and discuss the initial mechanism.

METHODSixty male SD rats (three month old)were randomly assigned: 6 week control (C6,) and 6 week model (M6) 6 for each group, 12 week model (M12), big load (B12), small load (S12), peptide (P12), peptide + big load (PB12) and peptide + small load group (PS12) 8 for each group, eight fourteen month rats were taken in the natural aging group. The rats were killed by the end of 6th week and 12th week, tested the indicators.

RESULTCompare with group C6, the indicators in group M6 showed aging in different levels; Compare with group M12, weight training or soy polypeptide supplement in all intervention groups could increase the content of skeletal muscle superoxide dismutase (SOD), SOD/MDA, the serum growth hormone(GH), insulin-like growth factor-1 (IGF-I)and skeletal muscle IGF-I mRNA, decreased the malondialdehyde (MDA) content of skeletal muscle, and they had notable interaction.

CONCLUSIONRat skeletal muscle aging model can be copied successfully by D-galactose hypodermic, and go on with 6-week weight training or soy polypeptide supplement, they can postpone the skeletal muscle aging process of D-galactose rats, and the two interference way united can have more obvious effect. Its preliminary mechanism may be related to the reduction of skeletal muscle oxidative stress and lipid peroxidation, the correction of hormones and related factors metabolic disorders, the elevation of skeletal muscle IGF-I mRNA expression and so on.

Objective To investigate the effect of over-expressed Cyr61 on the expression of extracellular matrix of human renal tubular epithelial cells(HKC), and explore the role of Cyr61 in the pathogenesis and development of autosomal dominant polycystic kidney disease(ADPKD). Methods Cyr61 gene cDNA was amplified by RT-PCR. A recombinant plasmid pcDNA3.1+ Cyr61 was constructed by cloning Cyr61 gene into pcDNA3.1. HKC cells were transfected with wild-type Cyr61 plasmid vector (pcDNA3.1+Cyr61). Then the fusion of Cyr61 gene and expression of its protein were detected by RT-PCR and Western blot. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ, and laminin were determined in four groups (the untransfected cells, pcDNA3.1 transfected cells, pcDNA3.1+Cyr61 -transfected cells and cyst-lining epithelial cells) by fluorescence quantum PCR. Results The amount of Cyr61 protein in Cyr61-transfected cells and cyst-lining epithelial cells were much greater than the control. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ and laminin in Cyr61-transfected cells were all amplified significantly, and the level of collagen Ⅳwas much higher than collagen I(P

Objective:To establish the model of apoptosis of activated human ??T cells induced by restimulating with Mycobacterium tuberculosis antigen(Mtb-Ag). To investigate the roles of p38 and phosphatidylinositol 3 kinase(PI3K) pathways in the apoptosis of activated human ??T cells induced by restimualting wih Mtb-Ag.Methods:Mtb-Ag activated human T cells(MtbAT) were cultured for 15 days to 25 days and restimulated with three concentrations of Mtb-Ag for 24 hours, and the apoptosis of ??T cells were measured by flowcytometry(FCM) using Annexin-V-FITC/PI staining. Mtb-AT were restimulating with Mtb-Ag(10 ?g/ml) for 3, 6, 12 and 24 hours, the apoptosis of ??T cells were detected. Mtb-AT cells were pretreated with SB203580(an inhibitor for p38 pathway), or LY294002(an inhibitor for PI3K pathway) for 60 minutes, and restimulating with Mtb-Ag for 3 hours, the apoptosis of ??T cells were detected.Results:Both 10.0 and 20.0 ?g/ml Mtb-Ag significantly induced the apoptosis of ??T cells(P0.05). Compared with control, the apoptosis of ??T cells could be significantly induced by restimulating MtbAT with Mtb-Ag(10.0 ?g/ml) for 3, 6, 12 and 24 hours(P0.05) in the percentages of apoptosis of ??T cells restimulated by Mtb-Ag(10.0 ?g/ml) between for 3 hours and for 24 hours, the percentages of apoptosis of the latter is higher than the former about 7.55%. The apoptosis of ??T cells induced by restimualting wih Mtb-Ag could be inhibited by SB203580(80.0 ?mol/L) or LY294002(10.0 ?mol/L), the inhibition rate of apoptosis was 91.6% and 43.1%, respectively.Conclusion:We established the model of apoptosis of activated human ??T cells by means of using Mtb-Ag(10.0 ?g/ml) to restimulate activated ??T cells for 3 hours. The test of inhibitors of signalling molecule suggested the signalling pathways including p38 and PI3K, participated in the apoptosis of activated human ??T cells restimulated by Mtb-Ag.
