Objective To present our initial experience in laparoscopic radical prostatectomy performed through an umbilical incision using a home-made multichannel port. Methods From August 2009 to March 2010, we performed single-port laparoscopic radical prostatectomy in 11 patients with localized prostate cancer. A home-made multichannel port was inserted extraperitoneally through a 3-cm umbilical incision. The single port extraperitoneal procedures included obturator fossa lymphadenectomy, radical prostatectomy and urethro-vesical anastomosis, while the urethro-vesical anastomosis was performed by a slip-knot running suture technique. Data were collected and analyzed prospectively. Results All cases were completed successfully, without conversion to a standard laparoscopic approach or open surgery except adding an additional port in one case. The average operative time was 256 minutes (range195-315), and the mean blood loss was 90 ml (range 20- 180), without any blood transfusion. The postoperative hospital stay was 15.4 days (range13- 24), and the Foley catheter was removed 12 days after surgery. No intraoperative complications occurred. One patient developed a vesico-rethralanastomosis leakage, 2 had lymphatic leakage and 1 had urinary tract infection,all of the cases were managed successfully with conservative treatment. Histopathological results showed negative surgical margine and negative lymph node dissection. All patients had no biochemical relapse after an average follow-up of 7 months. Conclusions Single-port laparoscopic radical prosta tectomy is feasible, cosmetic and minimally invasive with a low complication rate and good short-term outcome. Additional investigation is needed to evaluate the long-term safety and oncologic adequacy of this new approach.

Objective: To investigate the effect of miR-135a on the malignant biological behaviors of human laryngeal carcinoma epithelial Hep-2 cells and its sensitivity to oxaliplatin. Methods: Samples of laryngeal carcinoma tissues and para-cancerous tissues were collected from 10 patients who underwent laryngectomy in Nanyang Hospital Affiliated to Zhengzhou University-Nanyang City Center Hospital from January 2018 to June 2018. The expression of miR-135a in laryngeal carcinoma tissues and Hep-2 cells was detected by qPCR.After being transfected with miR-135 inhibitor, cell proliferation viability of Hep-2 cells was measured by CCK-8 assay, cell colony formation ability was detected by colony formation assay, and cell proliferation invasion and migration abilities were detected by Transwell analysis, and the expression of SOX2 protein in Hep-2 cells was detected by WB. Hep-2 cells transfected with miR-135 inhibitor were further treated with various concentrations (0.5, 1.0, 1.5 and 2.0 μmol/L) of oxaliplatin, and the cell proliferation viability was detected by CCK-8 while cell apoptosis was detected by Annexin-V-FITC/PI double staining flow cytometry. miR-135a inhibitor plasmid, control pcDNA empty vector (SOX2-Con) plasmid, and pcDNA-SOX2 (SOX2-OE) plasmid were transfected into Hep-2 cells to construct the miR-135a inhibitor+SOX2-Con group and miR-135a inhibitor+SOX2-OE group, and the cell viability, cell colony formation ability, cell invasion and migration ability in two groups were detected. Results: Compared with para-cancerous tissues, miR135a expression in laryngeal cancer tissues was significantly increased (P<0.01). Compared with normal NHP cells, miR-135a expression in Hep-2 cells was significantly increased (P<0.01). miR-135a inhibitor significantly reduced the expression level of miR-135a in Hep-2 cells (P<0.01). miR-135a knockdown significantly reduced the cell proliferation viability, cell colony number, migration, invasion and SOX2 expression in Hep-2 cells (all P <0.01), but significantly enhanced the sensitivity of Hep-2 cells to oxaliplatin (P<0.01). Compared with miR-135a inhibitor+SOX2-Con group, the cell proliferation viability, cell colony number, migration and invasion of Hep-2 cells in miR-135a inhibitor+SOX2-OE group were significantly increased (P<0.01); Meanwhile, the cells of the 2 groups were treated with different concentrations of oxaliplatin, and the results of CCK-8 assay showed that, compared with the miR-135a inhibitor+ SOX2-Con group, the cell proliferation viability of Hep-2 cells in miR-135a inhibitor+SOX2-OE group was significantly increased (P< 0.01). Conclusion: miR-135a knockdown inhibits the malignant biological behaviors and promotes oxaliplatin-sensitivity of Hep-2 cells possibly by inhibiting the expression of the transcription factor SOX2.

Objective:To investigate the experience and results of the modified lateral prostate capsule sparing robot-assisted radical cystectomy-orthotopic ileal neobladder (LPCS-RARC-OIN).Methods:From December 2018 to November 2020, 19 patients received LPCS-RARC-OIN by a single surgeon in Sun Yat-sen Memorial Hospital, Sun Yat-sen University. LPCS-RARC-OIN was performed on male patients with high-risk non-muscle-invasive bladder cancer or muscle-invasive bladder cancer cT 2N 0M 0 without tumour in the bladder neck or urethra, and prostate cancer was ruled out by MRI and serum PSA<2.5ng/ml. The average age was 57.6 years, the average IIEF-5 score was 20.4. Separating the prostatic adenoma and the lateral prostate capsule from the base to the apex of the prostate, and retaining the lateral prostate surgical capsule or lateral prostate capsule about 1-2mm thickness. Patients were followed up and urinary function, sexual function and oncological outcomes were recorded. Results:All 19 operations were finished successfully. The average operation time was 279.9 (225-345) min and average estimated blood loss was 88.9 (30-200) ml. The average postoperative hospital stays was 15.8 (9 -23) days. The average lymph node yields was 23.3 (11-42). All surgical margins were negative and no incidental prostate cancer was found. 2 weeks, 1 month, 3 months and 6 months after catheter removal, the daytime and nighttime continence were 42.1% (8/19)and 36.8% (7/19), 63.2% (12/19)and 63.2% (12/19), 78.9% (15/19) and 73.7% (14/19), 94.7% (18/19) and 89.5% (17/19), respectively. 3 months and 6 months after operation, the average IIEF-5 score was 7.2 and 10.1 points respectively. The average follow-up was 10.6 months (5.4-26.1 months)and no recurrence or distant metastasis was found in this study.Conclusions:LPCS-RARC-OIN could improve the urinary and sexual function in selected patients. However, the long-term follow up is needed for functional and oncological outcomes.

【Objective】 To investigate the effect of allogeneic platelet-rich on the healing and regeneration of diabetic foot wounds. 【Methods】 A total of 86 patients with diabetic foot ulcer treated in our hospital from January 2019 to June 2020 were selected for this study. They were divided into 2 groups by the random number table method, with 43 patients in each group. The control group was given conventional treatment according to the Guidelines for the Diagnosis and Treatment of Diabetic Foot in China, and the observation group was further treated with platelet-rich gel (APG) from the allogeneic blood bank.The clinical efficacy, general conditions, wound conditions, inflammatory factors, serum levels of transforming growth factor-β1 (TGF-β1), vascular endothelial growth factor (VEGF) and hyaluronic acid (HA) were compared between the two groups. 【Results】 The total effective rate of patients in the observation group was 93.02%, higher than 76.73% in the control group (P<0.05). The wound healing time (15.08±3.19 vs 17.38±4.02) d and hospitalization time (16.12±4.03 vs 18.27±5.11) d in the observation group were shorter than those in the control group (P<0.05). Before treatment, there were no significant differences in hsCRP (4.25±0.39 vs 4.10±0.41) mg/L, TNF-α (5.70±1.29 vs 5.81±1.33) μ g/L and IL-6 (96.38±24.02 vs 99.64±25.17) mg/L between the two groups (P>0.05). After treatment, hsCRP (2.35±0.50 vs 2.83±0.44) mg/L, TNF-α(3.15±0.82 vs 4.02±1.07) μ g/L and IL-6 (50.82±18.54 vs 72.93±20.25) mg/L in the observation group were lower than those in the control group (P < 0.05). Before treatment, there were no significant differences in TGF-β 1 (5.66±1.25 vs 5.81±1.31) ng/L, VEGF (11.03±3.62 vs 10.83±3.72) μ g/L and ha (71.19±20.84 vs 70.82±21.03) mg/L between the two groups (P>0.05). After treatment, the levels of TGF-β 1 (17.29±4.09 vs 14.03±3.72) ng/L, VEGF (43.03±14.17 vs 37.04±11.05) and ha (177.96±39.08 vs 151.94±36.17) in the observation group were higher than those in the control group (P<0.05). 【Conclusion】 On the basis of conventional treatment, allogeneic blood bank concentrated platelet APG can effectively improve the curative effect of diabetic foot wound and shorten the wound healing time and hospitalization time. The mechanism may be related to reducing the level of inflammatory factors and increasing TGF-β 1, VEGF and HA.
