Objective To analyze the electrocardiogram and treadmill exercise performance in patients with coronary artery myocardial bridge.Methods 176 patients with myocardial bridging diagnosed by coronary angiography were selected in the study.The performance of myocardial bridge electrocardiogram and treadmill exercise of different depth and stenosis was observed.Results Deep in myocardial bridge ischemic ST segment and T wave changes were significantly higher than superficial type (x2 =11.02,P ＜ 0.01).Systolic myocardial bridge Ⅲ grade stenosis of ischemic ST segment and T wave changes were significantly higher than grade Ⅰ and grade Ⅱ (x2 =12.78,P ＜0.01;x2 =24.45,P ＜ 0.01).The positive rate of myocardial bridge deep in the treadmill exercise test was significantly higher than the superficial type.Myocardial bridge Ⅲ grade systolic stenosis,treadmill exercise test positive rate was significantly higher than grade Ⅰ and grade Ⅱ (x2 =9.23,P ＜ 0.05;x2 =6.76,P ＜ 0.01).Conclusion Patients with myocardial bridge have various changes in the electrocardiogram and treadmill exercise,changes in deep in the type and degree of stenosis Ⅲ grade systolic are obvious.

Objective To detect differentially expressed genes in prostate cancer by cDNA microarray. Methods Total RNA was isolated by one step protocol from prostate cancer (CaP) and from normal prostate,and Poly(A) +RNA was further purified through Oligitex mRNA Midi Kit.Then it was analysed for differentially expressed genes in CaP and normal prostate by cDNA microarray with 4 096 human genes. Results There were 341 differentially expressed genes between CaP and normal prostate,of which there were 128 down regulated and 213 up regulated ones for CaP. Among these genes,15 were the most significant with 6 down regulated and 9 up regulated. Conclusions cDNA microarray can be used effectively to find out differentially expressed genes in prostate cancer which is not regulated by any single gene.Many different kinds of genes are involved in the initiation and evolution of CaP carcinogenisis.

Objective To investigate the expression of E-cadherin in prostate cancer and its relationship with PSA. Methods E-cadherin expression of 56 prostate cancer samples were studied by immunohistochemical stain and its expression level was analyzed with respect to T-PSA, F-PSA and F/T ratio. Results 24 patients (43%) were normal and 32 patients (57%) were aberrant in E-cadherin expression. E-cadherin was related significantly to the grade and stage of cancer and the changes of F/T ratio.There were no significant relationship between E-cadherin expression and T-PSA or F-PSA. Conclusions E-cadherin expression may act as a marker to the malignant degree and the prognosis of the prostate cancer.

Interferon y (IFN-?) could enhance the metastatic potential of a variety of tumors via increasing expression of MHC class I molecules or other unidentified mechanisms. It has been demonstrated that transfection of T-cell costimulatory molecule B7 gene into tumor cells could increase tumor immunogenicity and render them susceptible to immune attack. In this study, we investigate whether transfection of B7-1 gene could antagonize IFN-?-induced tumor metastasis. Lipofectamine-mediated transfection was used to introduce murine B7-1 (mB7-1) gene or neo gene into a low-metastatic variant of B16 melanoma cell line. The transfectants and parent B16 cells were treated with 100U/ml of IFN-? for 36 h before being subjected to experimental metastasis assay. The expression of MHC class I and class II molecules on the cells was analysed by flow cytometry. Pre-treatment of parent B16 cells and mock gene-transfected B16 cells (B16-neo) with IFN-? significantly increased their lung-metastizing capacity, while the same IFN-? treatment of B16 cells transfected with mB7-1 gene (B16-B7-1) showed no increase in the number of lung metastatic nodules as compared with control cells. Almost equally elevated expression of MHC class I (H-2Kb and H-2Db) molecules was found on the surface of B16, B16-neo and B16-B7-1 cells. However, a much higher expression of class II (I-Ab) molecule on B16-B7-1 cells than that on B16 and B16-neo cells was observed. These results demonstrate that transfection of B7-1 gene into B16 melanoma could reduce its IFN-?-induced metastasis and that the elevated MHC class II expression on B7-1-expressing cells might play a role in the B7-1 -associated reduction of metastasis.

Objective To evaluate the clinical significance of antinuclear antibody (ANA) and ANA repertoire in the diagnosis of systemic sclerosis (SSc). Methods ANAs were tested in 64 pa tients with SSc and 30 healthy controls by applying indirect immunofluorescence (IIF) and immunoblotting (IB). Results IIF-ANA assay showed that the positive rate of ANAs was 98. 4% (63/64) in SSc, and ANA staining was mainly shown as homogeneous-nucleolar pattern; IB-ENA test indicated that the antinuclear antibodies were mainly anti-Scl-70, anti-SS-A and anti-nRNP in SSc, and the positive rate was respectively 65.1% (41/64), 29.7% (19/64) and 6.3% (4/64). Conclusion Existence of multiple antibodies in SSc patients may hint that the patients might have other autoimmune diseases or increased risk for other autoimmune diseases. Besides, IB assay significantly increases the sensitivity and specificity of ANAs measurement, and contributes to the diagnosis of SSc.

Objective To evaluate ANA and ANAs as a indacation of systemic sclerosis diagnostic.Method ANAs were tested in 58 patients with SSc and 20 healthy controls by indirect immunofluorescence (ⅡF)and immunoblot(IB).Results ⅡF-ANA results indicated that the positive of ANAs were 98.3%(57/58)in SSc,and ANA pattern were mainly homogeneous-nucleolar,IB-ENA results indicated that the antinuclear antibodies were mainly anti-Scl-70.anti-SSA and anti-nRNP in SSc.The positive of them were 63.8%、31.O%and 5.2%.Conclusions It suggested that the patients might have other autoimmune diseases or the dangerous of other autoimmune diseases,and the IB kits of euroimmun got better positives and specificities to ANAs,the method could provide more helps to diagnosis of SSc.

Objective To study the clinical significance of detection of infectivity index in patients before transfusion. Methods A total of 12 863 patients in hospital were examined for hepatitis B virus surface antigen(HBsAg),anti-hepatitis C virus(anti-HCV),anti-AIDS virus(anti-HIV)and treponemiasis test(TRUST)before operation and transfusion. Results The positive rates of HBsAg,anti-HCV,anti-HIV and TRUST were 12.59%,1.90%,0.02%and 0.80%respectively.Conclusion The detection of infectivity index before transfusion has a very,important role in the prevention of blood transmissible disease and reduction or medical treatment dispute caused by infection after transfusion.
