Objective To investigate the correlation between glycosylated hemoglobin(HbAlc),plasma NTproBNP and the cardiac function in patients with acute coronary syndrome(ACS).Methods 53 patients with both ACS and type 2 diabetes mellitus(T2DM)(T2DM group),67 patients with ACS(ACS group)were selected as the objects.The HbAlc level was detected by immunohistochemical than turbidimetry,and the content of NT-proBNP was detected by electrochemiluminescence method.Results The levels of HbAlc,plasma NT-proBNP of the T2DM group were(9.21±1.23)％,(3.56±1.12)ng/ml,respectively,which were higher than those of ACS group[(5.09±0.67)％,(0.14±0.04)ng/ml](t=6.495,9.277,all P＜0.01);The cardiac function of ACS patients was positively correlated with the levels of HbA1c and plasma NT-proBNP(r=0.517,0.589,all P＜0.01),and there was positive correlation between the levels of HbAlc and plasma NT-proBNP in ACS patients(r=0.431,P＜0.05).Conclusion The HbAlc and NT-proBNP can promote the injury of the cardiac function of ACS patients,and can be used as diagnostic indicators of the injury of the cardiac function of ACS patients.

Objective To study the different effects of hypertensive putamen hemorrhage with two different treatments of decompressive craniotomy and small bone window(keyhole) surgery. Methods Retrospective analysis of 120 cases of hypertensive putamen hemorrhage in patients with operation data was carried out. They were randomly divided into two groups according to the different surgical procedure, and then compared the incidence of postoperative complications, close and long-term effects and so on. Results There was no significant difference in early complication rate and postoperative GOS score after a week between two groups(P＞0.05). The difference was significant between two groups in close and long-term effects (P ＜ 0.05 ). Conclusion Small bone window (keyhole)surgery had characteristics such as surgical time-saving ,less damage and more rapid recovery with removal of hematoma, and made played a significant role in promoting the recovery of close and long-term effects with patients.

Background and purpose:To investigate the clinico- pathological characteristics, prognosis and diagnosis of primary renal sarcoma that is a rare, highly malignant tumor with poor prognosis and survival. Methods:9 cases of renal sarcoma in our hospital were reviewed and analyzed. Nephrectomy was the main treatment for the patients. All the specimens were stained with histochemicial and immunohistochemical method, correlated literatures were also reviewed.Results:The distributions of pathology were malignant fibrous histiocytoma leiomyosarcoma, liposarcoma, myxosarcoma synoviosarcoma. Immunohistiochemical test was essential for the diagnosis of renal sarcoma.Conclusions:Pain and palpable mass were the common symptoms. Early radical surgery remains the optimal treatment, the role of chemotherapy and radiotherapy in the treatment modalities of the disease is still controversial.

Background and purpose:Fatty acid synthase(FAS)is a new tumor marker,the high expression of which has been reported to be associated with poor prognosis of cancer patients.This study investigated the expression of FAS in transitional cell carcinoma(TCC) of bladder and its clinical significance.Methods:The expressions of FAS were detected by streptavidin-peroxidase immunohistochemical method in the paraffin embedded sections of 65 TCC patients and the clinical data had been reviewed.15 normal bladder tissues were used as control group.Results:The positive rate of the expression of FAS in TCC was 58.5%(38/65),while only 2 of 15 cases in control group expressed FAS protein.The difference was statistically significant,the expression of FAS was related to the histological grades and recurrence but not different pathological stages.Survival analysis revealed that the 5-yr survival rate was lower in FAS positive patients than in negative patients(18% vs.44%,P

Objective To explore the relationship between KISS-1 gene and metastasis of bladder carcinoma,and to study the effect of the stable expression of KISS-1 gene on the invasion of bladder carcinoma cell line T24.Methods Fluorescent quantitative PCR was used to detect the expression of KISS-1 mRNA in primary bladder carcinoma without metastasis and primary bladder carcinoma with metastasis.Recombinant vector pIRES2-AKS-1 was constructed and transfected into T24 cells.Single clone of stably transfected cells was screened,and the changes in the invasive ability of T24 cells was detected after transfection.Results The expression level of KISS-1 mRNA in primary bladder carcinoma with metastasis was significantly lower than that in primary bladder carcinoma without metastasis(P＜0.05).The expression of KISS-1 protein in the single clone of stably transfected cells increased significantly,and the invasive ability significantly decreased(P＜0.05).Conclusion KISS-1 gene is correlated with the metastasis of bladder carcinoma,and the up-regulated expression of KISS-1 gene can inhibite the invasiveness of T24 cell line.

Objective To study the effect of erythropoietin on cardiac function of the patients with acute mycardial infarction (AMI). Methods 48 patients with AMI successfully treated with thrombolytic therapy were randomized into two group,2000 units of recombinant human erytfu-opoietin(rh-EPO) were administrated once a time in therapeutic group,3 times on alternate days in one week and total for 4 weeks. The peak value of serum creatine kinase(CK) and creatinkinase isozyme MB (CK-MB)were measured, myocardial infarct size (S) was estimated by Hindmen's QRS scoring system, and the diameter of left ventricular end diastolic(LVEDd) and left ventricular injection fraction (LVEF) were determined with echocardiography at the 4th weekend in both groups. Results CK, CKMB and S in therapeutic group were lower than in control group (P < 0.05). LVEDd and LVEF were also improved in the therapeutic group. Conclusion rh-EPO can significantly lessen the size of isehemia and infarct myocardium, mitigate the infarction degree and improve the cardiac function slightly in AMI patients.

Objective To investigate the effect of preoperative pravastatin preconditioning on myocardial ischemia-repedusion(I／R)injury in patients undergoing cardiac valve replacement with cardiopulmonary bypass (CPB).Methods Sixty ASA Ⅱ orⅢpatients of both sexes aged 18-64 yr undergoing cardiac valve replacement under CPB were randomly divided into 4 groups(n=15 each)：control group(group C)and 3 pravastatin groups receiving oral pravastatin 10，20 and 40 mg respectively every night for 7 days before operation(group P1-3).The number of patients receiving dopamine(≥5 μg·kg-1·min-1)and adrenaline was recorded from the termination of CPB to the end of operation，from the end of operation to 12 h after operation，during 12-24 h after operation and during 24-48 h after operation.Venous blood samples were taken from central venous line for measurement of plasme cTnI and CK-MB concentrations at 7 days before operation，before induction of anesthesia，at opening of the aorta and at 2，24 and 48 h after opening of aorta.Results The number of patients receiving dopamine and adrenaline was significantly less in group P3 than in group C(P<0.05).Plasma CK-MB and cTnI concentrations were significantly lower in group P3 than in group C(P<0.05).Conclusion Preconditioning with oral pravastatin(40mg／d for 7 consecutive days)can protect myocardium against I／R injury in patients undergoing cardiac valve replacement with CPB.

Objective To study the potential effects of telomerase inhibitor on the apoptosis of bladder cancer cells. Methods A phosphorothioate oligonucleotide (PS ODN) with sequence 5′ d(TTAGGG) 3′, as the telomerase inhibitor, was incubated with a bladder cancer cell line EJ. Such treated cells were studied with many approaches for the telomerase activity, the growth status and the morphological changes. Results The PS ODN inhibited the telomerase activity in the cells, arrested the cell growth, and induced the apoptosis of the cells. Conclusions The apoptosis of bladder cancer cells could be induced by PS ODN with 5′ d(TTAGGG) 3′ sequence as a telomerase inhibitor.

Objective To study the telomerase activity in the tissue adjacent to bladder cancer and to investigate its clinical significance. Methods Telomerase activity was detected with telomeric repeat amplification PCR (TRAP) assay. The telomerase activity in the tissue adjacent to bladder cancer was evaluated. Results Telomerase activity was positive in the tissue samples adjacent to bladder cancer in 10 of the 24 cases(42%). Telomerase activity in the adjacent tissue has been related with the tumour grades and stages. The tumour recurrence was also related with the telomerase activity in the adjacent tissue. Conclusions The detection of telomerase activity in the tissue adjacent to bladder cancer could be a prognostic marker for bladder tumor recurrence.
