Objective To investigate the effect of repeat transurethral resection for superficial bladder cancer. Methods One hundred and twenty patients who were newly diagnosed superficial bladder cancer were divided randomly in to two groups by mechanical sampling method,60 patients underwent second of prostate TUPKVP 4 weeks after initial transurethral and received adjuvant MMC intravesically (experiment group) and the other 60 patients received adjuvant MMC following the initial TUPKVP(control group). The two groups were followed up by cystoscopy at 3-month intervals,and then compared the recurrences between the two groups. Carcinoma in situ or muscle invasive disease were excluded from the study. Results Mean following up time was 6-24 (12.0 ±6.5) months, within the following up period,recurrence was observed in 13 (21.7%, 13/60) patients in experiment group and in 38 (63.3%,38/60)patients in control group, there was signiticantly statistical difference between the two groups (P＜ 0.01). Of all the recurrences, the recurrence rate of high grade tumor was 26.2% (11/42) in experiment group and 70.0% (35/50) in control group,the recurrence rate in experiment group was obviously less than that in control group (P ＜ 0.01). Conclusions Repeat transurethral resection can lower the recurrence of superficial bladder cancer (especially for the high grade tumor) which with initial resection, it can improve the classification of malignant rumor, and find the residual tumor, so it has value in clinical treatment.

Objective To analyze the clinical effects of low molecular heparin calcium on early onset severe pre-eclampsia.Methods Sixty patients with early onset severe pre-eclampsia at 26-34 weeks of gestational age were divided into treatment group(28 cases)and control group(32 cases).The conventional treatment was delivered in control group and low molecalar heparin calcium(LMWHC)was used in treatment group additionally.The time of prolonged gestational age,umbilical arterial S/D ratio,amniotic fluid index,placenta weight,neonatal weight and Apgar score were measured in two groups.Results The time of prolonged gestational age was 10.19 ±4.57days in treatment group and 6.14 ±3.56 days in control group,which were significantly different(P ＜ 0.01).Umbilical arterial S/D ratio,amniotic fluid index,placenta weight and neonatal weight were all significantly different between the two groups(P ＜ 0.05).Neonatal Apgar score in treatment group was remarkably improved(P ＜ 0.01).Conclusion LMWHC treatment in the patients with early onset severe pre-eclampsia could extend gestational age,increase neonatal weight and improve perinatal outcomes.
