Objective To explore the relationship of the levels of adhesion molecules and cytokines with vascular disease in patients with type 2 diabetes (T2DM).Methods Ninety-six T2DM patients were selected as case group and divided into non-vascular group (28 cases),micro-vascular group (33 cases) and major vascular group(35 cases) according to vascular disease.Meanwhile,30 healthy persons were selected as control group.Serum levels of serum soluble intercellular adhesion molecule-1 (ICAM-1),vascular cell adhesion molecule-1 (VCAM-1),interleukin-6 (IL-6),tumor necrosis factor-α (TNF-α) and yon willebrand factor (vWF) were determined by Enzyme-Linked Immuno Sorbent Assay (ELISA),and the expression of adhesion molecule and cytokines of patients with T2MD at 2 weeks after treatment.Results Compared with control group,the levels of ICAM-1,VCAM-1,TNF-α and IL-6 in all subgroup of T2DM patients were significantly elevated(P < 0.05),and the levels showed an increasing trend with function deterioration (P < 0.05).The levels of ICAM-1,VCAM-1,IL-6 and TNF-α in case group before treatment were (505.34 ± 56.42) μg/L,(570.85 ±59.54) μg/L,(94.51 ± 18.04) ng/L,(70.57 ± 18.34) ng/L respectively,significant different from those of after treatment ((390.53 ±45.23) μg/L,(482.93 ± 69.85) μg/L,(77.31 ± 15.49) ng/L,(50.45 ± 12.66) ng/L; t =16.281,8.712,7.697,8.445; P < 0.05).There were significant positive correlation between ICAM-1,VCAM-1,IL-6,TNF-α and vWF in the case group(r =0.482,0.453,0.576,0.534 respectively,P < 0.05).Conclusion Adhesion molecules and cytokines are take part in the process of the deterioration of T2DM and the occurrence of vascular disease.

Objective: To compare the efficacy of two commercially available dentifrices (colgate total toothpaste containing triclosan and copolymer was used as the experimental and a toothpaste containing triclosan without copolymer the control) in the control of dental plaque and gingivitis. Methods: A double blind clinical study was conducted in 200 adult male and female subjects from Chengdu, China were entered into the study and stratified into two treatment groups which were balanced for age, sex, baseline of Quigley Hein plaque index scores(PI) and baseline of Loe Silness gingival index scores(GI). Subjects received an oral prophylaxis and were instructed to brush their teeth for one minute twice daily with their assigned dentifrice. Three and six months after application of the dentifrices plaque and gingivitis examinations were conducted. Results: At the end of the study, 183 subjects complied with the protocol and completed the entire six month study. Before use of the dentifrices GI in experimental and control groups was 1.63?0.36 and 1.68?0.34, it was 0.45?0.30 and 0.52?0.33 in 3 months, and 0.43?0.32 and 0.58?0.38 in 6 months( P

Objective To investigate the in-hospital death-related factors for acute encephalocele in patients with craniocerebral injury for craniotomy in order to provide evidence for clinical treatment and prognosis determina-tion.Methods The clinical data of 105 patients with craniocerebral injury occurring acute encephalocele during cra-niotomy were analyzed retrospectively.The correlations of the factors including sex,age,preoperative Glasgow coma scale(GCS)scores,preoperative intracranial pressure(ICP),postoperative pupil status,causes of encephalocel,post-operative GCS scores,postoperative ICP,coagulation mechanism,brain swelling,preoperative hypoxia,preoperative blood pressure and blood glucose were analyzed.Results The prognosis was assessed according to the Glasgow out-come scale(GOS)scores after procedure.There were 77 patients in death group(namely death cases)and 28 patients in survival group.Logistic regression analysis showed that postoperative GCS scores (Wald =14.127,Exp(B)=0.044,95%CI:0.032,0.448),causes of encephalocel(Wald =7.748,Exp(B)=8.183,95%CI:1.825,10.251), postoperative ICP(Wald =7.637,Exp(B)=7.637,95% CI:1.969,8.028),postoperative pupil status(Wald =4.001,Exp(B)=2.499,95%CI:1.019,5.122)and blood glucose(Wald =7.915,Exp(B)=8.891,95% CI:1.790,9.337)were closely associated with the in-hospital death in patients with acute encephalocele in craniocere-bral injury operation(P <0.05).Conclusion The postoperative GCS scores,causes of encephalocel,postoperative ICP,postoperative pupil status and blood glucose could be used as the important indexes for predicting in-hospital death of acute encephalocele in craniocerebral injury for craniotomy.To prevent the intraoperative encephalocele and reduce the intracranial pressure are the important measures to reduce the mortality rate of the patients with acute encephalocele.

Epilepsy is a common nervous system seizure disease in children,20%-30% of them is intractable epilepsy.The pathogenesis of intractable epilepsy in children is not yet identify.Some research think that this may be associated with resistance of a variety of diffe-rent mechanisms of antiepileptic drug and abnormalities of multidrug resistance gene expression.The most investigation of multidrug transpor-ter is P-glycoprotein,multidrug resistance-associated protein.They are present in cell membrane and belong to adenosine triphosphate-dependent membrane transport protein.Studies have showed that over-expression of multidrug transporter in temporal lobe brain tissue of patients with refractory epilepsy and animal model of chronic epilepsy reduce the concentration of therapeutic drug in cells.They result in resis-tance by releasing the energy and transferring large amounts of anti-epileptic drugs to exterior of brain capillary endothelial cells in way of active transport.The relationship between multidrug transporter′s structure,distribution,functions and drug-resistant epilepsy are reviewed.

Objective To investigate the apoptosis induced by adenovirus mediated PML growth suppressor in SGC-7901 gastric cancer cells. Methods Human full-length PML cDNA was cloned into shuttle plasmid pSGCMV, the constructed plasmid containing PML gene was co-transfected into 293 cells together with backbone plasmid pPE3 to obtain recombinant adenovirus Ad-pml. Ad-pml was used to infect SGC-7901 cells. The expression of p53 and bcl-2 in SGC-7901 cells and qualitative, quantitative index of cell apoptosis were detected with MTT, flow cytometry and immunohistochemical method. Results The growth of SGC-7901 cells was inhibited and the apoptosis rate was increased by adenovirus mediated PML in a MOI- dependent manner. The expression of p53 protein was increased and that of bcl-2 protein was unchanged in SGC-7901 cells after treated with adenovirus mediated PML. Conclusions Adenovirus mediated PML exerts its cytotoxic effect on SGC-7901 cells by inducing apoptosis. The increase of p53 protein expression is the mechanism inducing gastric cancer cell apoptosis.

Objective To investigate the effects of stimulation of CD40 on the growth,prolifera- lion and apoptosis of gastric cancer cell lines,and the change of gene expression profiles of gastric cancer cell AGS.Methods The growth and proliferation of AGS cells treated with different concentrations of soluble CD40 ligand were measured by MTT in order to choose optimum stimulating concentration of so- luble CD40 ligand.Cell cycle and apoptosis of AGS cells were analyzed by flow cytometry.Gene expres- sion profiles of AGS cells were analyzed by Affymetrix U133A 2.0 after treated with soluble CD40 ligand for 48 h.Results Two?g/ml of.soluble CD40 ligand was the optimum concentration.After being cul- tured with soluble CD40 ligand for 48h,the growth of AGS cell was inhibited and blockade in G1 phase. There were 414 alterative genes found in AGS cells including 209 up-regulated genes and 205 down-regu- lated genes.Forty-five genes varied significantly(P
