Objective To explore the effect of bcl 2 in vascular smooth muscle cells(VSMC) apoptosis induced by nitric oxide(NO),we investigated the effect of NO on Bcl 2 protein expression in cultured vascular smooth muscle cells(VSMCs),and effect of Bcl 2 over expression on apoptosis is(VSMCs) induced by NO. Methods Cultured rat VSMCs at passage 5 to 8 were used for experiments,S nitroso N acetypenicillamine(SNAP) was used as NO donor.Cells were preincubated for 24-48 hours in special culture dish with conditioned medium to reach quiescent,and then incubated in conditioned medium containing 0 5 mmol/L SNAP.After 8 to 10 hours,the cells were fixed and Bcl 2 expression was analyzed by ACAS 570 through fluorescent immunochemistry.Vascular smooth muscle cells were transfected with bcl 2 gene through retrovirus to allow overexpression of Bcl 2 in VSMCs.Finally,we observed the apoptosis in normal VSMCs and VSMCs infected with bcl 2. Results SNAP downregulated Bcl 2 expression in VSMCs.PCR and Southern hybridization confirmed the integration of the bcl 2 retrovirus vector into vascular smooth muscle cells genomic DNA.And fluorescence immunohistochemistry confirmed that Bcl 2 protein was overexpressed in VSMCs infected with bcl 2.And ratio of apoptosis become lower in VSMCs infected with bcl 2. Conclusion bcl 2 can inhibit apoptosis of VSMCs induced by SNAP.It is suggested that downregulation of Bcl 2 protein is one of the ways in which SNAP induces VSMCs apoptosis,and apoptosis in VSMCs induced by SNAP is regulated by bcl 2.;

Objective To study the function of cyclooxygenase 2(COX 2) and its specific inhibitor NS 398 on the cell growth and invasion ability of urothelial carcinoma cell line EJ. Methods The cox 2 cDNA was transfected into the urothelial carcinoma cell line EJ and a cell line EJ COX 2 which highly expressed cox 2 gene permanently was gained. The cell growth rate before and after transfection was observed. Then at various concentrations of NS 398, the invasion ability was detected by Boyden Chamber and expression levels of uPA by RT PCR and Western blot. Results The EJ COX 2 cell line grew more rapidly and had a stronger invasion ability than EJ and its uPA expression increased significantly. NS 398 could dose dependently inhibit the expressions of COX 2 and uPA and the invasiveness of EJ COX 2 cell. Conclusion COX 2 can stimulate the growth of urothelial cell line EJ and promote its invasion ability by stimulating the expression of uPA.

There was a significant difference in the clinical effect between observation group and control group (P<0.05).ConclusionComprehensive rehabilitation has a better effect on facial paralysis.

Objective investigate the correlation between plasma soluble receptor for advanced glycation endproducts (sRAGE) and arterial stiffness in patients with different types of metabolic syndrome (MS).Methods A total of 180 subjects were drawn from a epidemiologic follow-up study,including 60 cases non-metabolic syndrome (NMS),60 cases metabolic syndrome without diabetes mellitus (NDMMS),60 cases metabolic syndrome with diabetes mellitus (DMMS).Carotid femoral arterial pulse wave velocity (CFPWV) was assessed by the French KangPuLe atherosclerosis measurement instrument,and plasma sRAGE levels were measured by ELISA.Comparison of mean in multiple groups was conducted by analysis of variance.Multivariate analysis was done with multiple linear stepwise regression analysis.P ＜ 0.05 was considered as statistically significant difference.Results Compared with NMS group,plasma sRAGE levels were significantly lower in DMMS and NDMMS groups [(635.07 ± 229.20) pg/mL vs.(671.17 ± 358.16) pg/mL vs.(992.99 ± 427.83) pg/mL,P =0.001].CFPWV of DMMS group was significantly higher than that of NMDMS and NMS groups (14.22 ±3.14) m/s vs.(12.15 ±2.79) m/s vs.(11.66 ± 2.52) m/s,P =0.002).Plasma sRAGE level was negatively correlated with CFPWV (r =-0.278,P =0.005).(3) Multiple linear regression analysis demonstrated that age (β =-0.091,95％ CI-0.096 ～-0.095,P =0.031),HDL-C (β =1.295,95％ CI 1.231 ～ 1.360,P =0.022) and sRAGE (β =0.119,95％ CI 0.118 ～ 0.130,P =0.032) had a significant effect on CFPWV.Conclusions The increased arterial stiffness is closely related to the discreased plasma sRAGE levels in MS.Plasma sRAGE maybe a novel target for vascular disease prevention and treatment in patients with metabolic syndrome.

AIM:To study the correlation of serum uric acid ( UA) level with carotid plaques and arterial stiff-ness in the patients with essential hypertension ( EH) , and to explore the predictive value of serum UA for evaluating EH preclinically .METHODS:A total of 92 patients with EH and 30 healthy individuals were enrolled .The value of UA and other indicators were detected .B-mode ultrasound examination was performed to measure the common carotid artery intima -media thickness ( IMT) and the sites of plaque in the internal carotid-artery, external carotid artery and carotid bifurca-tions.Carotid-femoral arterial pulse wave velocity ( CFPWV) was assessed by Complior?atherosclerosis measurement in-strument.RESULTS:The serum level of UA in the patients with EH was higher than that in control group [(361.51 ± 83.81) μmol/L vs (317.03 ±62.22) μmol/L, P<0.05].The mean value and abnormal rate of IMT between hyperten-sion group and control group were significant difference [(0.69 ±0.14) mm vs (0.60 ±0.12) mm, 42.39%vs 10.00%, P<0.05].In 92 EH patients, 45 cases had carotid plaques .These 45 cases were divided into 3 groups according to the plaque severity, among which the serum UA level had statistically significant differences [(285.25 ±78.41) μmol/L, (341.19 ±63.99) μmol/L and (401.33 ±88.49) μmol/L, P<0.05].Compared with rigid plaque group ( n=34), the serum UA level in soft plaque group (n=11) was significantly higher [(389.00 ±69.45) μmol/L vs (323.03 ± 72.71) μmol/L, P<0.05].A stepwise multiple linear regression analysis demonstrated that age ( r=0.414), systolic blood pressure (r=0.224), pulse pressure (r=0.270) and uric acid (r=0.219) were predisposed factors for higher CFP-WV (P<0.05).CONCLUSION:UA is one of the risk factors causing hypertension .Serum UA level may reflect the sever-ity and stability of carotid plaques .The increased arterial stiffness is closely related to the increased serum UA level in EH .

Objective:To quantify the tryptase and T cell immunoglobulin mucin domain-3(TIM-3)double positive mast cells in hu-man chronic periodontitis tissue using double immunofluorescence staining.Methods:25 healthy controls,28 chronic mild periodontitis and 30 chronic advanced periodontitis patients were included.The gingival specimens were stained with HE for histology,and with double immunofluorescence staining for the identification of tryptase and TIM-3 double positive mast cells in gingival tissue.Results:In chronic periodontitis tissue the degree of gingival inflammation was significantly increased,the densities(cells/mm2 )of tryptase and TIM-3 double positive mast cells were significantly increased(P<0.05),in addition,that in chronic advanced periodontitis group was significantly higher than in the chronic mild periodontitis group(P<0.05).Conclusion:Tryptase and TIM-3 double positive mast cells has the similar tendency as the severity of periodontitis inflammation in human periodontitis tissue.Tryptase and TIM-3 double positive mast cells may play an important role in human chronic periodontitis.

The expressions of estrogen receptor (ER) α,ERβ1,and ERβ2 in thyroid carcinoma,thyroid adenoma,and adjacent normal thyroid tissue were determined by RT-PCR and immunohistochemistry,and the relationship of expression levels of three ERs and the main clinical pathologic parameters were evaluated.The result showed that ERα mRNA expression in papillary thyroid carcinoma(PTC) tissues was significantly higher than adjacent normal tissue,while,ERβ2 mRNA expression in PTC tissues was significantly lower than normal tissue ( P＜0.05 ).The positive expression of ERβ1 and ERβ2 in the thyroid carcinoma was related with the histological variant of carcinomas; the ERβ2 expressions were related with the lymph node metastasis and TNM staging of the carcinomas.These results suggest that the decreased ERβ2 expression may induce proliferation and carcinogenesis of thyroid follicular epithelial cells as well as progression of the carcinoma,and is a powerful prognostic indicator.
