Objective To compare the safety and efficacy between RevoLix 2 μ m continuous-wave (CW) laser resection of bladder tumor and transurethral resection of bladder tumor (TURBT) in patients with non-muscle-invasive bladder tumor, and to evaluate clinical value of 2 μ m CW laser resection for nonmuscle-invasive bladder tumor. Methods 62 patients with non-muscle-invasive bladder tumor were divided into 2 groups including 2 μ m CW laser resection group (32 cases) and TURBT group (30 cases) according to the random number table.The intravesical instillation of pirarubicin was performed regularly. The operative time,drop in hemoglobin,indwelling catheterization time,and operative complications were analyzed.Results All cases were completed successfully. The mean operative times of 2 μm CW laser resection group and TURBT group were 32.5±10.5 min and 31.3± 9.8 min, respectively, and no statistical difference could be found between both groups (t =0.364,P=0.674).3 cases were found to have obturator nerve reflex in TURBT group,but no obturator nerve reflex was found in 2 μn CW laser resection group.Bladder irrigation time of 2 μm laser resection group was statistically shorter than that of TURBT group [ (6.2±2.6)h vs (23.8±6.5)h,t =8.294,P=0.006]. There was also no significant difference in postoperative catheterization time between both groups [(4.2±1.5)d vs (5.2±1.8)d,t=1.468,P=0.103 ]. Postoperative hospitalization time of the two groups was not shown significant difference [ (5.3± 1.5) d vs (5.8±2.8) d,t =0.627,P =0.531 ].All cases were followed up for 6~18 months,and there were no significant difference in the recurrence rate between both groups (x2=0.481,P =0.562). Conclusion 2 μm CW laser resection is a novel excellent treatment for non-muscle-invasive bladder tumor and has the similar effect as TURBT with the advantage of significantly less blood loss and rapid recovery after surgery.

Objective To measure the level of circulating endothelial progenitor cell (EPC) and serum vascular endothelial growth factor (VEGF), and to investigate its clinical significance in patients with different stages of renal cell carcinoma (RCC). Methods The level of circulating EPC was quantified by assaying CD45-CD34+VEGFR-R2 +cell phenotype in 45 patients with RCC (RCC group), 30 patients with benign renal tumors(benign renal tumors group) and 30 healthy controls (control group). Serum VEGF was quantified by enzyme- linked immunosorbent assay (ELISA). The results were compared. Results The level of EPC in RCC groups was (0.265 ± 0.042)%, in benign renal tumors group was(0.053 ± 0.008)% , and in control group was (0.048 ± 0.006)%. The level of EPC in RCC group was significantly higher than that in benign renal tumors group and control group (P<0.05). The level of EPC in Ⅲ- Ⅳ stage patients was significantly higher than that in Ⅰ-Ⅱ stage patients:(0.312 ± 0.038)%vs. (0.215 ± 0.021)%, P<0.05. Three months after operation, the level of EPC in 33 RCC patients without pretreatment was (0.078 ± 0.003)% and significantly lower that before treatment (P<0.05). The level of VEGF in RCC groups was (305.5 ± 29.1) ng/L, in benign renal tumors group was (29.8 ± 3.2) ng/L, and in control group was (25.1 ± 2.8) ng/L. The level of VEGF in RCC group was significantly higher than that in benign renal tumors group and control group (P<0.05). The level of VEGF inⅢ-Ⅳstage patients was significantly higher than that inⅠ-Ⅱstage patients:(365.6 ± 34.6) ng/L vs. (256.2 ± 23.2) ng/L, P<0.05. Pearson association analysis showed that the level of EPC had positive associations with VEGF (r=0.714, P<0.01). Multiple linear regression showed that the size of kidney neoplasms was a dependent factor for the level of EPC. Conclusions The level of EPC has a positive association with VEGF. EPC maybe a new biomarker for RCC.

Objective To observe the effect of saikosaponin-d on transcriptional activation of estrogen receptor in rat hepatic stellate cells(HSC-T6), and to explore its pharmacological mechanism. Methods The rat HSC-T6 were cultured in vitro for the study. After transient transfection of HSC-T6 with the ER-specific reporter gene ERE-tk-Luc by liposome, the effect of saikosaponin-d and estradiol on luciferase activity was observed by Dual-Luciferase Reporter Assay System under the conditions of various drug concentrations, various treatment time and addition of estrogen receptor inhibitor ICI182. 780. Results When the concentrations of saikosaponin-d and estradiol were in the range of 0.01-5 μmol/L, 0.01-1 μmol/L respectively, luciferase activity was increased in a dose-dependent manner . Luciferase activity arrived the highest when saikosaponin-d concentration was 5 μmol/L and estradiol concentration was 1 μmol/L, but the effect was weakening when estradiol concentration reached 5μmol/L. In respect of the effect of treatment time, when HSC-T6 were separately treated with 5μmol/L of saikosaponin-d and 1 μmol/L of estradiol for 24 h, the luciferase activity was the highest. And ICI182.780 could significantly inhibit the induction of saikosaponin-d and estradiol for luciferase activity. Conclusion Saikosaponin-d has an effect on promoting the transcriptional activation of estrogen receptor in HSC-T6.
