In type 2 diabetic patients the f re quencies of point mutations 3316G→A and 3394T→C in mitochondrial DNA (mt DNA) were 3.9% (6/152) and 5.3% (8/152) respectively, which were significantly higher than those in normal controls and patients with coronary heart disease. This fi nding suggests that mtDNA 3316G→A and 3394T→G mutations are related to type 2 diabetes.

0.05).Conclusions:The incidence of CIN and especially high-grade CIN are higher in patients with positive high risk types of HPV-DNA than negative. HPV-DNA testing has significance in the diagnosis of cervical displasia;HPVDNA testing combined with pap smear and colposcopy can increase the diagnosis of cervical diaplasia.

Objective To observe therapeutic effects of treating stroke hemiplegia with acupuncture combined with rehabilitation training. Methods 72 patients with stroke hemiplegia were randomly recruited into a control group and a treatment group, with 36 patients in each group. The treatment group was treated with acupuncture combined with rehabilitation training and the control group was treated with acupuncture exclusively. Both scalp acupuncture and body acupuncture were used in the process of treatment. Results There was statistical significance (P<0.01) between the two groups in functional rehabilitation of limbs and ADL score (P<0.01) . Conclusion The treatment of stroke hemiplegia with acupuncture combined with rehabilitation training is more effective than that of treating with acupuncture exclusively.

Objective To investigate the change of surface molecules and cytokine expressions of dendritic cells (DC) stimulated with recombinant proteins Com1 and heat shock protein B (HspB) of Coxiella burnetii (Cb).MethodsThe DC cultured for 5 d were stimulated with 20 μg/mL recombinant protein Com1,20μg/mL HspB or 6 μg/mL E.coli lipopolysaccharide (LPS).Twentyfour hours later,the surface mature marker,CD83,and activation-associated markers of T lymphocytes,CD58,CD54,CD40,CD80 and CD86,and expression levels of interleukin (IL)-10 and IL-12 of DC were detected by fluorescence activated cell sorter (FACS).Multiple comparisons were performed by using Student-Newman-Keuls test.ResultsCom1 could induce DC maturation efficiently in vitro.Human monocyte-derived DC exhibited significantly higher expression levels of surface molecules including CD83,CD54,CD58,CD80,CD86,and CD40,which were all ＞80％.CD83 expression induced by Com1 was similar with that induced by 1E.coli LPS,while CD54 and CD86 expressions were slightly higher than those induced by E.coli LPS,and expressions of other molecules were significantly higher than those induced by E.coli LPS (all P＜0.05).After Com1 stimulation,intracellular IL-12 level increased to 9 ％ from zero.HspB could not induce DC maturation in vitro.The intracellular IL-10 level was 6％ after HspB stimulation.DC pulsed with Com1 and HspB exhibited intracellular IL-12 level of zero and IL-10 level of ＜2％.Conclusion Com1 but not HspB can efficiently activate DC and Com1-activated DC can drive T cells toward Th1 cell development due to a high level of IL-12 production.

Objective To approach the effect of acrylonitrile (ACN) on the proliferation and differentiation of the lung fibroblasts of mice. Methods The purification and primary culture of the lung fibroblasts(LFb)of new born mice were conducted. The cells were treated with ACN added in the medium at the varying doses of 0.01, 0.5, 1.0, 10.0, 50.0, 100.0 and 200.0 ?g/ml. The cytomorphological methods were used, the protein, malonaldehyde (MDA) and the activity of superoxide dismutase (SOD) were determined. Results No inhibitted effect on the lung fibroblasts was observed at the doses of 0.01-10.0 ?g/ml. At the doses of 50.0-200.0 ?g/ml, acrylonitrile could inhibit the differentiation and proliferation of the cells, the volume of cells became small,the rate of cell clusters decreased, at the doses of 10.0-200.0 ?g/ml, the content of protein and the activity of SOD decreased, MDA content increased. Conclusion Acrylonitrile can inhibit the proliferation and differentiation of the lung fibroblasts in mice, protein synthesis inhibition and lipid peroxidation are considered as the related factors.

Objective To observe the effect of advanced glycosylation end products(AGEs) on gene expression of connective tissue growth factor(CTGF) in NIH Swiss mouse embryo fibroblasts(NIH/3T3),and to assess the intervention actions of aminoguanidine(AG) and puerarin(Pue) on CTGF mRNA expression in NIH/3T3.Methods AGEs were synthesized by coincubation of BSA with glucose.The AGEs content was measured by fluorescence spectroscopy.NIH/3T3 cells were treated with AGEs(prepared with 20,50,80 mmol?L-1 glucose) for 24 h.The NIH/3T3 cells were treated with AGEs(prepared with 50 mmol?L-1 glucose) for 0,6,12,24 and 48 h.The intervention actions of AG and Pue with different concentration(0.25,0.5,1.0 and 1.5 g?L-1) were evaluated.The CTGF mRNA expression in NIH/3T3 was determined by RT-PCR.Results Compared with BSA control,the CTGF mRNA expression levels in NIH/3T3 were increased by treatment with AGEs(prepared with 20,50,80 mmol?L-1 glucose) for 24 h(P

Great changes in drug metabolizing enzyme (DME) expression occur in the fetus and child during development. Individual hepatic DME ontogeny can be categorized into one of three groups based on developmental trajectories.Some enzymes such as CYP3A7,are expressed at highest level in the fetus dur-ing the first trimester and either remain elevated or slightly de-crease during gestation,but are silenced or reduced to relatively low levels within one to two years after birth.SULT1 A1 is an ex-ample of the second group of DME.These enzymes are ex-pressed at relatively constant levels throughout gestation and into adulthood.CYP3A4 belongs to the third DME group .These en-zymes are expressed at negligible or low levels in the fetus.Sig-nificant increases in enzyme levels are exhibited within the first one to two years after birth.The epigenetic regulation refers to genomic modifications that do not involve changes in DNA se-quence and include DNA methylation,histone modifications, and non-coding RNAs.The epigenetic regulation mechanisms are responsible for the developmental expression of DME genes dur-ing liver maturation.This review will provide a summary of DME developmental expression profiles and reveal epigenetic mecha-nisms underlying variable drug metabolism and drug response. Thus,knowledge regarding DME ontogeny has permitted im-proved capability to predict drug disposition in pediatric pa-tients,which is crucial for improving drug dosing leading to opti-mal safety and efficacy in children.

Objective To compare the prognosis effect of different Helicobacter pylori (Hp)eradication methods in patients with chronic gastritis.Methods One hundred and twenty patients with chronic gastritis diagnosed by gastroscopy and pathology examination were divided into sequential therapy group (36 cases),triple-combined therapy group (34 cases),Hp positive without eradication group (30cases) and Hp negative group (20 cases) according to the Hp infection status.All patients were followed up by gastroscopy,biopsy and rapid urease test before and after therapy.Results The Hp eradication rate in sequential therapy group was 94.44％ (34/36),in triple-combined therapy group was 73.53％ (25/34),and there was statistical difference (x2 =5.775,P =0.016).The symptoms scores and gastroscopy scores after therapy in the four groups were significantly lower than those before therapy,and there were statistical differences (P ＜ 0.05).The symptoms scores and gastroscopy scores after therapy in sequential therapy group were significantly lower than those in triple-combined therapy group,and there were statistical differences (P ＜0.05).The symptoms scores and gastroscopy scores after therapy in sequential therapy group,triple-combined therapy group and Hp negative group were significantly lower than those in Hp positive without eradication group [(0.84 ± 0.60),(1.34 ± 0.59),(1.49 ± 0.62) scores vs.(2.98 ± 0.54) scores,(0.47 ± 0.37),(0.83 ± 0.35),(0.96 ± 0.75) scores vs.(1.22 ± 0.40) scores],and there were statistical differences (P ＜ 0.05).Conclusions The Hp eradication rate of sequential therapy is higher than that of triple-combined therapy.The two therapy methods can both improve the symptoms score and gastroscopy score,but the symptoms after sequential therapy are relieved faster compared with triple-combined therapy.
