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 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 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 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.

AIM: To observe the enhanced green fluorescent protein (EGFP) gene expression and cytotoxicity in human adipose derived adult stem cells (hADSCs) by pEGFP-N1, Ad5-EGFP and rAAV-2/1-EGFP, and investigate the suitable gene-transferred vehicle. METHODS: The experiment was conducted at Chinese National Human Genome Center and the Third Hospital of Peking University from January to July 2006. ①After the patients and their relative were informed consent, the subcutaneous adipose tissue was obtained from the patients undergoing routine total hip joint replacement in Department of Orthopaedics, Third Hospital of Peking University. pEGFP-N1 was provided by Clotech Company, Ad5-EGFP and rAAV-2/1-EGFP by Vector Gene Technology Company. ②hADSCs were cultured in vitro after isolated from the adipose tissue after dissected and digested with type I collagenase. ③hADSCs of passage 3 were infected with pEGFP-N1, Ad5-EGFP and rAAV-2/1-EGFP and the EGFP expression and the cell toxicity were observed. ④Twenty-four hours after being transfected, 5?104 cells were reseeded in a 24-well plate and the solution was changed three times every week. The growth curves of each group were drawn. Normal non-transfected cells served as control. The influence of different transfection ways on the growth of hADSCs was observed. RESULTS: ①Comparison of transfected efficiency with different ways: pEGFP-N1 transfection showed a higher cytotoxicity and lower efficiency of 10.5%; Ad5-EGFP could efficiently transfect hADSCs (multiplicity of infection=5?102, 82.5%); when MOI was 0.05); however, the growth capability of hADSCs was decreased significantly in the pEGFP-N1 transfection group compared with the control, and the differences were significant at day 3-10 after transfection (P
