In order to assess the effect of long-term versus short-term intravesical chemotherapy in preventing the recurrence of patients with non-muscle-invasive bladder cancer, we searched several databases with words as mesh terms and free text words to find all eligible randomized clinical trials (RCTs) for the comparison of the two strategies of instillation durations. "Observed-Expected events research (O-E)" and "Variance (V)" for calculating hazard ratio (HR) were used in Revman 5.2 software recommended by Cochrane Collabration for data analysis. Sensitivity and subgroup analysis were selected to minish heterogeneity. GRADEpro 3.6 profile recommended by Cochrane Collabration was employed for quality assessment of analyses. Finally, 13 eligible RCTs with 4216 patients were included in this review and 16 comparisons from 13 trials were involved for analysis. The pooled analysis revealed no significant difference between long-term and short-term duration [HR=0.99, 95% CI (0.89, 1.11), P=0.89]. Within the subgroup analysis, patients benefited from long-term instillations with a start regimen of one immediate instillation [HR=0.83, 95% CI (0.69, 1.00), P=0.05]. But patients were not suitable to receive long-term instillations with epirubicin (EPI) [HR=1.01, 95% CI (0.91, 1.13), P=0.78]. The progression rate was not reduced after long-term instillations [HR=0.96, 95% CI (0.66, 1.39), P=0.82]. From our results, patients should not receive introvesical chemotherapy more than half a year. In contrast, patients with one immediate instillation are preferred to have a long-term duration at least one year. Long-term instillations can not reduce the progression rate.

Objective To report 3 cases of using the EXIT(ex-utero intrapartum treatment)procedure in the peri-surgical caring of congenital diaphragmatic hernia of neonatus.Methods Preparing and consulting of multiple clinical departments before operation,inhibit uterine contraction to avoid placental abruption.Keep puerperae and their babies warm.Result No complications happened to neither maternity nor neonatus.Conclusion Co-operations of multiple clinical departmens were essential to the successful using the EXIT(ex-utero intrapartum treatment)procedure in the congenital diaphragmatic hernia of neonatus.

Objective To analyze the electrocardiography(ECG)data of pressure overload-induced cardiac hy pertrophy rats.Methods Pressure overload cardiac hypertrophy was induced by abdominal aorta constriction. Echocardiogram and heart weight measurement demonstrated the occurrence of cardiac hypertrophy.Standardized ECG parameters of limb and chest were measured and statistically analyzed.Results Two weeks after hypertrophy models were established,echocardiogram showed greater LVPWTd,IVSTd,LVDd.ECG showed that left axis deviation and higher R waves in V_A,V_B,V_C(P

Objective:To supply the reliable evidence for a further research of the TCM syndrome of hyperuricemia and treating it with traditional Chinese medicine,we try to verification the risk factors and to research TCM syndrome differentiation for diagnosis in patients with hyperuricacidemia.Methods: We selected cases according to the standard of hyperuricacidemia's diagnose and adopted the method of retrospective and prospective analysis.Each of cases was investigated and filled in the form.These data were processed through statistical method in the end.Results: Clinical investigation selected 109 cases patients with hyperuricacidemia.First,male group incidence rate was higher than female.Second,incidence rate was increasing with age(r=0.826 p

Objective To investigate the acute effect of dialysate calcium concentration on calcium balance and blood pressure(BP) of maintenance hemodialysis(MHD) patients with normal serum tCa,and to provide scien- tific basis for individualized calcium concentration dialysate formula.Methods For 4 weeks,dialysate with different calcium concentrations as DCa 1.25,DCa 1.5 and DCa 1.75 was used in 15 stable MHD patients.Arterial blood pressure was measured before and after each dialysis session,and every 30 minutes during hemodialysis session.Serum total calcium and ionized calcium were assessed before and after each dialysis session with different calcium concen- trations dialysate.Results With the DCa 1.2.5,BP,serum tCa and iCa decreased as compared with pre-dialysis val- ues(P

Objective To investigate the relatonahip between TNF-α and ventricular arrhythmias after acute myocardial infarction(AMI)and its mechanism.Method Both the clinical and animal experiments were done.(1)Clinical experiment:Eighty patients with AMI were included in Union Hospital,Tongji Medical College,Huazhong University of Science and Techology,from May 2005 to November 2006 according to the WHO diagnostic criteria.Co-infection of diseases such as severe upper respiratory infection,lung infection,high fever,cancer,et al were excluded.The relationship between the levels of TNF-α and arrhythmias were observed at different times after AMI.A straight line correlation,analysis Was done.(2)Animal experiment:Different concentrations of TNF-αwere added to isohted rat hearts for observing the arrhythrnia effects.The effect of TNF-α on intracellular Ca2+ concentration was detected by laser confocal technique.All data were analyzed by SNK-q test using SPSS 13.0 sofeware prograrn.Results(1)The plasma levels of TNF-α were significantly associated with the Lown class of PVC after AMI and they were higher in AMI of anterior wall[(46.41±10.34)pg/ml]than other positions [(28.25±6.35)pg/ml,P<0.05].2)The frequency of ventricular arrhythmias was interrelated with the concentralions of TNF-α.Using etanercept beforehand,TNF-α induced a slight increase of intracellular Ca2+ intensity (P<0.05).Conclusions There was a relationship between TNF-αlevels and ventricular arrhythmisa in patients with AMI.Animal experiments confirmed the isolated heart perfusion with TNF-α induced ventricular arrhytrnias.Expression of TNF-α after AMI was related with the occurrence of ventricular arrhythrnias.The effect might be associated with the increased inuaeellular Ca2+ intensity caused by TNF-α.
