Objective:To investigate the 2 years’ efficacy of intravesical instillation of domestic BCG versus epirubicin in the prevention of recurrence of intermediate-risk or high-risk non-muscular invasive bladder cancer and predictive factors of BCG instillation.Methods:From July 2015 to June 2020, 18-75 years old patients with moderate to high-risk non muscle invasive bladder cancer (NMIBC) confirmed by pathological examination were involved. The ECOG score was 0-2. Exclusion criteria included ①immune deficiency or impairment (such as AIDS), using immunosuppressive drugs or radiotherapy, suspected allergic to BCG or epirubicin or excipients of the two drugs, fever or acute infectious diseases including active tuberculosis or receiving anti tuberculosis treatment, with severe chronic cardiovascular and cerebrovascular diseases or chronic kidney disease; ②combined with other urogenital system tumors or other organ tumors; ③combined with muscle invasive bladder urothelial carcinoma (≥T 2); ④undergoing chemotherapy, radiotherapy or immunotherapy within 4 weeks (immediate instillation after surgery not included); ⑤ pregnant or lactating women; ⑥ comfirmed or suspected bladder perforation; ⑦gross hematuria; ⑧cystitis with severe bladder irritation that may affect the evaluation; ⑨participat in other clinical trials within 3 months; ⑩alcohol or drug addiction; ?any risk factors that may increasing the risk of patients. Epirubicin 50 mg was irrigated immediately after the operation(TURBT or laser resection). The patients were randomly divided into BCG15 group, BCG19 group and epirubicin group by the ratio of 2∶2∶1, and the patients were maintained intravescical instillation for 1 year. The recurrence and adverse events of the three groups were compared. Univariate and multivariate analysis was performed to predict the risk factors of BCG irrigated therapy failure. Result:By June 15, 2020, the median follow-up duration was 22.1 months(12.1, 32.3), and there was no statistical difference between the groups ( P=0.9024). There were 274 patients enrolled in BCG19 group, 277 patients enrolled in BCG15 group and 130 patients enrolled in the epirubicin group. The drop-off rate was 16.6%(113 cases)and made no difference between groups( P=0.6222). There were no significant difference in age, gender, BMI, or ECOG score( P>0.05). During the follow-up, 116 cases was detected recurrence or progression. The recurrence rate of the three groups was 14.2% and 14.8% in BCG19 group and BCG15 group, and 27.7% in the epirubicin group. There was no difference in recurrence rate between BCG19 and BCG15 group( P=0.9464). The recurrence rate of BCG19 group was lower than that of the epirubicin group ( P=0.0017). The recurrence rate of BCG15 group was lower than that of the epirubicin group ( P=0.0020). There was no difference in the cumulative recurrence free survival rate between BCG19 and BCG15 group (95% CI0.57-1.46, P=0.7173). The cumulative recurrence free survival rate of BCG 19 group was better than that of the epirubicin group( HR=0.439, 95% CI0.26-0.74, P=0.0006), and the cumulative recurrence free survival rate of BCG15 group was better than that of the epirubicin group ( HR=0.448, 95% CI0.29-0.80, P=0.0021). The total incidence of adverse events in 19 BCG19, BCG15 and epirubicin group were 74.5%, 72.6% and 69.8% respectively. There was no difference in the incidence of adverse events between BCG19 and BCG15 group( P=0.6153). The incidence of adverse events in epirubicin group was lower than that of BCG19( P=0.0051) and BCG15( P=0.0167) groups.There was no significant difference in the incidence of serious adverse events (SAE) among the three groups ( P=0.5064). Log rank test univariate analysis and Cox risk regression model multivariate analysis showed that the history of bladder cancer recurrence( HR=6.397, 95% CI1.95-20.94, P=0.0001)was independent risk factor for BCG irrigation failure. Conclusions:The 2 years’ efficacy of intravesical instillation of domestic BCG is better than than of epirubicin with good tolerance and safety. There is no difference between BCG19 and BCG15 group. BCG doesn’t increase SAE compared with epirubicin. Recurrence status was an independent prognostic factor regarding recurrence-free survival.

Objective:To explore the effect of the interval of radical prostatectomy after prostate puncture on the perioperative period and prognosis of patients.Methods:Patient’s data from September 2016 to September 2018 whom performed laparoscopic radical prostatectomy at the Affiliated Hospital of Xuzhou Medical University were collected and retrospectively analyzed. All prostate biopsy confirmed prostate cancer and 66 patients underwent laparoscopic radical prostatectomy. The average age was (70.11 ± 5.01) years, ranged from 60 to 79 years. The patients were divided into two groups according to the interval time from prostate biopsy to laparoscopic radical prostatectomy: <7 d group ( n=32) and 6-8 weeks group ( n= 34). The operation time, intraoperative blood loss, postoperative hospital stays, positive rate of incisional margin, postoperative urinary incontinence rate and the rate of urinary incontinence 6 months after operation, rate of postoperative erectile dysfunction and bone metastasis were compared and analyzed between the two groups. When the data conformed to the normal distribution, the data were expressed in Mean±standard deviation ( Mean± SD), and the independent sample t-test was used to evaluate the statistical significance between groups. When the data did not conform to the normal distribution, the measurement data was expressed as Median (interquartile range) [ M( P25, P75)], and the Mann-Whitney U test was used for the comparison between groups. Count data comparison between groups using Chi-square test or Fisher exact probability method. Unconditional multivariate Logistic regression was used to analyze the relationship between outcome and exposure. Results:All the 66 patients successfully underwent surgery, the surgery success rate was 100%. The average operation time of <7 d group and group 6-8 weeks group was [185.00(174.50, 193.50)] min and [183.00(175.00, 187.50) min], respectively, the difference was not statistically significant ( P=0.685 8, U=512.0). The average intraoperative blood loss of group <7 d group and 6-8 weeks group was [185.50(177.75, 205.25)]ml, [189.00(180.75, 206.00)] ml, respectively, the difference was not statistically significant ( P=0.685 9, U=512.0). The average postoperative hospital stays of <7 d group and 6-8 weeks group was [14.00(11.75, 16.00)] d, [13.50(12.00, 15.00)] d, respectively, the difference was not statistically significant ( P=0.785 7, U=522.5). The positive rate of incisal margin of<7 d group and 6-8 weeks group was 18.75%, 14.71%, respectively, the difference was not statistically significant ( P=0.659 5, χ2=0.194). The postoperative urinary incontinence rate of <7 d group and 6-8 weeks group was 6.25% and 8.82%, respectively, the difference was not statistically significant ( P=1.000 0). The urinary control after follow-up for six months of <7 d group and 6-8 weeks group was 6.25% and 2.94%, respectively, the difference was not statistically significant ( P=0.607 7). The postoperative erectile dysfunction rate of<7 d group and group 6-8 weeks group was 9.38% and 8.82%, respectively, the difference was not statistically significant ( P=1.000 0). The postoperative bone metastasis rate of group<7 d and 6-8 weeks group was 6.25% and 5.88%, respectively, the difference was not statistically significant ( P=1.000 0). Conclusions:Performing laparoscopic radical prostatectomy within 7 days following prostate biopsy did not adversely affect the postoperative outcomes and prognosis, also not increased postoperative complications, can shorten the patient′s treatment cycle.

The efficacy and safety of BCG in the prevention of postoperative recurrence of intermediate and high-risk non-muscle invasive bladder cancer: a randomized, controlled, multi-center clinical trial (mid-term report) / 中华泌尿外科杂志

Objective To investigate the efficacy and safety of intravesical instillation of BCG vaccine in the prevention of early recurrence of middle and high risk non-muscle invasive bladder cancer.Methods From July 2015,patients with non-muscle invasive bladder cancer aged 18-75 years with informed consent were screened and underwent transurethral resection of bladder tumor (TURBT).Immediately intravesical instillation of epirubicin 50 mg was given postoperatively.After pathology was comfirmed,patients was enrolled in group 1 (BCG15) or group 2 (BCG 19) or the control group (epirubicin 18) randomly with SAS 9.3 software.Data of follow-up and Adverse event was collected and analyzed.Results By May 31,2019,531 patients were enrolled in the study.The drop-off rate was 20.1％.167 patients (143 males and 24 females)in group 1,172 patients (141 males and 31 females)in group2 and 84(75 males and 9 females) in the control group with follow-up data were analyzed.There were no significant differences in age,gender,BMI,ECOG score,risk stratification between the three groups (P =0.8641,P =0.2906,P =0.9384,P =0.6126).The median follow-up time makes no statistical difference between the groups (P =0.9251),12.0 (6.0,22.5) months,13.0 (6.0,22.3) months,and 13.0 (7.0,22.3) months.The median recurrence time of the three groups was 4.0 (3.0,6.0) months,4.5 (3.0,9.8) months,4.5 (3.0,8.8) months.There was no statistical difference between the three groups (P =0.2852).Risk stratification in the patients got no significant difference between the three groups (P ＞ 0.05).The 1-year recurrence-free survival rates were 80.0％ in the group 1 and 88.3％ in the group 2 and 73.7％ in the control group.The group 2 was superior to the group 1 and the control group (P =0.0281,P =0.0031).There was no significant difference between group 1 and control group (P =0.2951).There was no significant difference in the cumulative recurrence-free survival between the experimental group 1 and the experimental group 2,(95％ CI 0.80-2.43,P =0.2433).The cumulative recurrence-free survival in the group 1 and the group 2 was better than the control group (95 ％ CI 0.31-0.92,P =0.0266;95 ％ CI 0.20-0.65,P =0.0008).All the cases underwent instillation were analyzed for adverse events.The incidence of overall AE(adverse events) in group 1 was 68.5％ (152/222),the incidence of grade Ⅰ-Ⅱ AE was 53.2％ (118/222),the incidence of grade Ⅲ-Ⅳ AE was 15.3％ (32/222).The incidence of overall AE in the group 2 was 71.8％ (160/223),the incidence of grade Ⅰ-Ⅱ AE was 60.1％ (134/223),and the incidence of grade Ⅲ-Ⅳ AE was 11.7％ (26/223).The overall AE rate in the control group was 53.2％ (59/111),of which the incidence of grade Ⅰ-Ⅱ AE was 42.4％ (47/111),and the incidence of grade Ⅲ-Ⅳ AE was 10.8％ (12/111).There was no difference in the incidence of overall AE between the group 1 and the group 2 (P =0.4497).The incidence of AE in the two experimental groups was higher than that in the control group (P =0.0062,P =0.0008).There was no difference in the incidence of grade Ⅲ-Ⅳ AE between the three groups (P =0.3902).Conclusions BCG(19 instillation schedule) has a better effect on preventing recurrence after 1 year of bladder surgery,which is superior to epirubicin group.The long-term efficacy of BCG in preventing recurrence and the efficacy of different schedules need to be further followed up.The lower urinary tract symptoms,which are mainly urinary frequency,are one of the causes of case fallout and should be fouced in future.Compared with epirubicin,BCG perfusion does not increase the incidence of grade Ⅲ-Ⅳ adverse reactions,and is safe to use.

Expression of LIM and SH3 protein 1 in renal clear cell carcinoma and its effects on invasion and migration of renal clear cell carcinoma 786-O cells / 中华肿瘤杂志

Objective@#To investigate the expression of LIM and SH3 protein 1 (LASP1) in renal cell carcinoma and its significance in the invasion and migration of renal clear cell carcinoma 786-O cell line.@*Methods@#The expression level of LASP1 in 41 cases of renal cell carcinoma tissues and normal renal tissues was analyzed by immunohistochemistry. The relationship between the expression level of LASP1 and clinical characteristics was further analyzed. Expression of LASP1 in 10 cases of tumor tissues with or without lymph node metastasis was analyzed by Western blot. Furthermore, small interfering RNA (siRNA) targeting LASP1 was constructed and transfected into 786-O cells to downregulate LASP1 expression. The interference effect of LASP1 siRNA on LASP1 protein and the expression of related proteins in epithelial mesenchymal transition (EMT) pathway were detected by Western blot. The effects of LASP1 knockdown on cell proliferation, migration and invasion and gene expression were then assessed using CCK8 assay, transwell cell migration system and western blot analysis, respectively.@*Results@#The positive rate of LASP1 expression in renal clear cell carcinoma tissues was 90.2% (37/41), which was significantly higher than that in the adjacent tissues (29.3%, P=0.002). The expression of LASP1 in renal cell carcinoma was positively correlated with lymph node metastasis and TNM stage of renal cell carcinoma (P<0.05). The results of Western blot showed that LASP1 (0.696±0.053) was highly expressed in renal cell carcinoma (1.459±0.628), especially in cases with lymph node metastasis (2.692±0.186, P<0.05). The LASP1 siRNA remarkably down-regulated the expression of LASP1 protein in 786-O cells. The abilities of proliferation, invasion and migration of 786-O cells were decreased significantly in the LASP1 siRNA groups.The relative expression of E-cadherin protein in the siRNA group (0.848±0.020) was significantly higher than those in the siRNA-NC group (0.671±0.018) and control group (0.691±0.037, P<0.05). The relative expression of N-cadherin protein in the siRNA group (0.449±0.047) was significantly lower than those in the siRNA-NC group (0.613±0.018) and control group (0.633±0.045, P<0.05). The relative expression of vimentin protein in the siRNA group (0.477±0.029) was significantly lower than those in the siRNA-NC group (0.598±0.069) and control group (0.633±0.045, P<0.05 for both).@*Conclusions@#LASP1 is highly expressed in renal clear cell carcinoma, which is closely related to the development of the cancer. The effects of LASP1 on the invasion and migration of 786-O cells and lymph node metastasis may be related to the EMT.

Advancement of Reovirus-based therapy for cancer / 国际肿瘤学杂志

Reovirus,a kind of oncolytic viruses, is seldom pathogenic, but is selectively able to replicate in cancer cells through activation of Ras signaling. Pre-clinical studies have demonstrated that treatment with reovirus is associated with significant anticancer activity across a range of tumor types. Further clinical evaluation of reovirus therapy has shown that it is well tolerated when administered locally or systemically. Encouraging anticancer efficacy has been observed with single-agent treatment and in combination with chemotherapy and radiotherapy. High safety and promising efficacy of reovirus has raised hopes that it will become a new anticancqt agent.

That of Ki67 was 32.8%, with the expressions of Fas and Ki67 showing a negative correlation (r = -0.62, P < 0.05). In contrast, the expressions of FasL and Ki67 showed a positive correlation. (r = 0.93, P < 0.01). The Fas expression of stage I was significantly higher than that of stages III and IV. The expression rate of FasL in RCC was significantly increased with RCC stage (P < 0.01). (2) The apoptotic rate of TIL in RCC (33.9%) was significantly higher than that of the normal kidney tissues (3.5%, P < 0.01). The expression of FasL and the apoptotic rate of TIL in RCC gave a positive correlation (r = 0.96, P < 0.01). (3) Fas expression rate in 786-0 cells was 13.7%. The apoptotic rate mediated by FAsAb was 9.6%. IFN alpha was able to up-regulate the Fas expression and subsequently augment the FasAb-mediated apoptosis in 786-0 cells. But IL2 did not show similar effects. (4) The FasL expression rate of 786-0 was 18.6%. FasL expressed by 786-0 cells was able to induce apoptosis of Jurkat T-cells in co-culture assays and the apoptosis of Jurkat T-cells was significantly lowered after blocking the effect of FasL with Fas-neutralizing antibody NOK-2, giving the apoptotic rates of 14.9% and 2.0%, respectively, the difference therein is statistically significant (P < 0.01).</p><p><b>CONCLUSION</b>Down-regulation of Fas expression and up-regulation of FasL-expression are the mechanisms through which the RCC cells escape from immune attack.</p>

Effect of Epidural Analgesia with Morphine and Bupivacaine in Patients after Receiving Prostatectomy / 医药导报

To observe the analgesic effects of morphine and bupivacaine for the patient controlled epidural analgesia (PCEA) after prostatectomy. Methods: 21 patients after receiving prostatectomy were treated with PCEA including morphine and bupivacaine, and 24 patients were treated with routine analgesia as control. The effects of analgesia with visual analogue scale (VAS) were evaluated indirectly, and episodes of bl adder spasm were recoreded. Results: The effects of PCEA on postoperative analgesia and controlling bladder spasm were much better than that of routine analgesia. Conclusion: Effects of morphine and bupivacaine used in PCEA for post-prostatectomy analgesia are confirmed adm inistration is slimple. Because of their dosage is smalller and side effects are fewer, this treating protocol is beneficial for the recovery of the patients re ceiving prostatectomy.

Expression and implication of Fas and FasL modulate by cytokines in renal cell carcinoma cells / 中国免疫学杂志

Objective:To investigate the role of cytokines in modulating expression of Fas and FasL in renal cell carcinoma cells(RCCs) and its implication.Methods:Combination treatment of 786 0 and GRC 1 cells with cytokines including IFN??IFN?,IL 2,TNF? and anti Fas monoclonal antibody (FasAb) to induc apoptosis.FasL function was assessed by coculture assays in vitro using renal cancer cells 786 0 or GRC 1 and Fas sensitive Jurkate T cells.Results:1.Either IFN? or IFN? could up regulate the Fas expression and subsequently augment the Fas mediated apoptosis in 786 0 and GRC 1 cells.2.IFN? and IFN? could up regulate the FasL expression in 780 0 and GRC 1 cells.And subsequently augmente the apoptosis of Jurkat T cells cocultured with 786 0 and GRC 1 cells.IFN? had the same effects on 786 0 cells.IFN? had the same effects on GRC 1 cells.Conclusion:IFN? and IFN? could agument the Fas mediated apoptosis of RCCs by enhancement of Fas expression,but they also up regulate the expression of FasL in RCCs and subsequently augmente the apoptosis of RCCs by enhancment the apoptosis of T lymphocytes by Fas/FasL pathway.

Investigation on immune tolerance induced by portal venous inoculation of donorspleen cells combined the CsA / 中国免疫学杂志

With the hereotopic heart transplantation, immune tolerance induced by portal venous inoculation of donor spleen cells was studied.Methods:The recipient rats received donor spleen cells through portal vein combined with of cyclosporine A(CsA).The NK cell activity and IL-2, IFN-y expression of recipient spleen cells were detected. Results: Hie inoculation of donor spleen cells through the portal vein could significandy prolong survival time of heart allografts.IL- 2, IFN-y expression of recipient spleen lymphocytes and the recipient NK cell activity was also inhibitied.Conclusion:The inoculation of donor spleen cells through the portal vein could induce immune tolerance.The suppression of IL-2-NK-IFN-y immunologic net may be an important mechanism of portal vein tolerance.
