ABSTRACT

Objective@#To compare the curative effect of three different surgical methods: peritoneal varicocele ligation, peritoneal single-port laparoscopy and microscopy on varicocele.@*Methods@#Retrospective analysis of the case data of 150 patients with varicocele treated in the Affiliated Hospital of Xuzhou Medical University from September 2016 to September 2018. The average age was 24.5 years, and the age range was 22-30 years. The patients were divided into three groups according to different surgical methods: open group, laparoscopy group and microscope group, with 50 cases in each group. Patients in the open group were treated with retroperitoneal spermatic cord ligation. Patients in the laparoscopic group were treated with single-hole laparoscopic laparoscopic surgery. Patients in the microscope group were treated with microscope surgery. Operation time, postoperative hospitalization time, hospitalization cost reserved arteries, surgical complications (such as testicular hydrocele, scrotal edema, epididymitis, testicular atrophy), recurrence, and semen quality improvement were compared between three groups. Measurement data were expressed as mean ± standard deviation(Mean±SD), the two comparisons used the t test, the comparison between the three groups used the analysis of variance, and the comparison between the count data groups using the Chi-square test.@*Results@#The operation time of the patients in the microscope group [(52.52 ± 4.29) min] was longer than that of the open group [(36.60±3.69) min] and the laparoscopic group [(39.54±2.87) min]. The difference between the two groups was statistically significant (P<0.05); but the postoperative hospitalization time and hospitalization cost of patients in the microscope group [(2.16±0.95) d, (5 251 ± 300) yuan] were higher than those in the open group [(3.80±0.78) d, (64 75±415) yuan)]and the laparoscopic group [(3.28±1.01)d, (7 379±273) yuan] . The results of pairwise comparison showed that the difference between the microscope group, the open group and the laparoscopic group was statistically significant (P<0.05). Arterial preservation in the microscope group [47(94.0%)] were compared with the open group [35 (70.0%)], and laparoscopic group [30(60.0%)] had obvious advantages. Pairwise comparison results showed that the comparison between the microscope group and the open group and the laparoscopic group was statistically significant (P<0.05). After follow-up for six months, 2 cases were lost to follow-up in the microscope group, 1 cases were lost to the open group, and 5 case was lost to the unilateral laparoscopic group. 2(4.2%) patients had complications in the microscope group, and 14 (28.6%) patients had complications in the open group; 9 (20.0%) patients had complications in the laparoscopic group, and the total incidence of complications showed a pairwise comparison, the difference between the microscope group, the open group and the laparoscopic group was significant (P<0.05). The recurrence rate in the microscope group was 2.1% (1/48), the recurrence rate in the open group was 18.4% (9/49), and the recurrence rate in the laparoscopic group was 13.3% (6/45); the recurrence rate was compared in pairs, the difference between the microscope group, the open group and the laparoscopic group was significant (P<0.05) . The improvement rate of semen quality in the microscope group was 68.8% (33/48), the open group was 42.9%(21/49), the laparoscopic group was 55.6%(25/45), pairwise comparison results showed that the microscope group compared with the open group and laparoscopy group, the difference were statistically significant (P<0.05).@*Conclusions@#Microscopic surgery has less trauma, faster postoperative recovery, shorter operation cost and hospitalization time. Postoperative complications and recurrence, and improved semen quality are all superior to open spermatic vein ligation and single-hole umbilical laparoscopic surgery, it is a safe and effective way to treat varicocele.

ABSTRACT

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.

ABSTRACT

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.

The mean operation time was (132 ± 12) minutes, and the mean WIT was (29 ± 8) minutes. Clinical parameters, the single glomerular filtration rates (sGFR) were compared before the operation and after 3 and 12 months in order to observer the effects on renal function and find the factors predicting the renal function impairment.</p><p><b>RESULTS</b>There were significant differences between 3, 12 months after the operation ((26.8 ± 5.6) ml/min and (28.6 ± 5.6) ml/min, respectively) and preoperation ((31.9 ± 6.3) ml/min) in sGFR (F = 4.882 and 5.511, both P < 0.05). And there were significant negative correlations between the sGFR in 3 and 12 months after the operation and WIT (r = -0.569, P = 0.000 and r = -0.448, P = 0.004) . The preoperative sGFR (β = 0.260, 95%CI:0.089-0.431) and WIT (β = 0.369, 95%CI:0.189-0.555) were independent predictors for function decline of the operated kidney (both P < 0.05). The analysis showed that the effects of WIT within 30 minutes on renal function is relatively small. Longer WIT was associated with lower postoperative sGFR values (F = 22.128 and 20.552, both P = 0.000) .</p><p><b>CONCLUSIONS</b>For the LPN operation, the longer of the WIT, the more serious of renal function damage. sGFR is an accurate measurement to assess the renal damage. Every effort should be made to minimise WIT during LPN, and the limit of 30 minutes should be not exceeded.</p>

ABSTRACT

Aim To explore the protective effect of Sertoli cells on the co-transplanted allogeneic renal cells in male and female recipient rats. Methods Testicular Sertoli cells were prepared by digestion with trypsin, collagenase and DNase, while renal cells were prepared by digestion with trypsin alone. FasL and Fas expressions were detected respectively by FCM before transplantation. About 106 cells were injected into the allogeneic renal subcapsule. In order to demonstrate the survival of renal cells, the expression of g-PG in graft was examined by SABC method. Apoptosis of the lymphocytes surrounding the graft was observed by TUNEL(terminal deoxynucleotidyl transferase-mediated X-dUTP nick end labeling). Results The grafts were analyzed histologically 20 days after transplantation. The renal cells transplanted alone were all rejected, while the survival rates of the mixed cell transplantation were 87.5% and 77.8% in male and female recipients respectively. When the renal cells co-transplanted with Sertoli cells treated by anti-FasL mAb, only 30.0% grafts were survived. Apoptosis of lymphocytes surrounding the graft were quite evident. Conclusion Sertoli cells expressing FasL can protect renal cells from allograft rejection by inducing apoptosis of Fas expressing T cells surrounding the grafts.

ABSTRACT

Purpose:To compare the sensitivity and specificity of urinary cytokeratin test with voided urine cytology in detection of bladder cancer and to evaluate their clinical values. Methods:For 136 patients suspected to have bladder cancer urinary concentrations cytokeratin 8 and 18 and cytology were conducted in the same voided urine samples. Of them 87 patients with bladder transitional cell carcinoma were confirmed histologically The sensitivity and specificity of urinary cytokeratin and urine cytology were analyzed. 49 patients without bladder cancer were selected as control.Results:The overall sensitivity and specificity of urinary cytokeratin test were 70.1% and 73.3%,respctively ,those of urine cytology were (42.5%) and 83.7%, respectively, there was no significant difference between the specificity of urine cytology and that of urinary cytokeratin test ;however, urinary cytokeratin was significantly more sensitive than urine cytology in detection of any stages and grades of bladder cancer (P
