Objective To present our initial experience of pure laparoendoscopic single-site surgery (LESS) for radical cystectomy and bilateral pelvic lymph node dissections. Methods 10 patients with pathology confined bladder urothelial carcinoma underwent laparoendoscopic single-site radical cystectomy, including 9 males and 1 female. After a 3-4 cm lower median abdominal incision was made, quadport or homemade single multichannel port was inserted, and conventional and prebent laparoscopic instruments were utilized. The surgical procedure included bilateral pelvic lymphadenectomies, radical cystectomy and building with a sigmoid orthotopic neobladder by open surgery.Results No extra port needed, neither conversion to open or conventional laparoscopic surgery. The time of LESS procedure ranged from 130 to 330 min (mean 243 nin). Estimated blood loss ranged from 50 to 600 ml (mean 270 ml). 5 patients needed blood transfusion of 2 to 4 units. The pathologic evaluation revealed bladder urothelial carcinoma, negative margins and negative pelvic lymph node involvement. No mortality or severe complications were observed perioperatively. After followup of more than 6 months, all revealed controllable urination at daytime, while 4 revealed nocturnal incontinence and needed one or two pads during nighttime. No evidence of recurrent or metastatic disease was detected. Conclusions LESS radical cystectomy and bilateral lymphadenectomies was safe and feasible, and short-term follow-up showed good tumor control outcomes. Homemade single multichannel port made of two elastic ring and glove was simple and effective.

OBJECTIVETo investigate the effect of docetaxel on the interaction between C-jun and androgen receptor (AR) in prostate cancer LNCaP cells and its androgen-independence subtype LNCaP-bic cells.

METHODSLNCaP and LNCaP-bic cells were treated with docetaxel and the changes in AR and AP-1 expression were evaluated using luciferase assay. Western blotting and immunoprecipitation assay were employed to analyze the effects of docetaxel on the expressions of C-jun and AR and their interaction.

RESULTSLuciferase assay showed that LNCaP and LNCaP-bic cells expressed higher levels of AR and C-jun after docetaxel treatment. Docetaxel induced a higher level of p-c-jun expression in LNCaP-bic cells than in the parental LNCaP cells. Western blotting showed a strong PSA protein expression in LNCaP-bic cell after docetaxel treatment. Docetaxel caused a stronger interaction between AR and C-jun in LNCaP-bic cells.

CONCLUSIONDocetaxel activates ligand-independent AR transcription, and the interaction between AR and C-jun may affect the outcome of docetaxel chemotherapy.

OBJECTIVETo investigate the effect of RNA interference of IgG gene on the radiosensitivity of the human prostate cancer PC3 cell line.

METHODSPC3 cells were trasnfected via lipofectamine by the shRNA vector FCGR1AshRNA targeting the Fc segment of IgG, using NCshRNA as the negative control. Q-PCR and Western blotting were used to analyze the expression of IgG in the trasnfected cells. The cells were then exposed to ⁶⁰Co γ ray at 0, 2, 4, 6, 8, 10 Gy, and the cell proliferation was evaluated by MTS and the cells apoptosis estimated by flow cytometry at 12, 24 and 48 h.

RESULTSMTS assay showed that ⁶⁰Co γ ray significantly inhibited the proliferation of PC3 cells transfected with FCGR1AshRNA as compared with NCshRNA-transfected and blank control cells (P<0.05). Flow cytometry showed that the cell apoptosis rate was significantly higher in FCGR1AshRNA group than in NCshRNA and blank control groups at 48 h after γ ray exposure (P<0.05). At 12, 24 and 48 h after 6 Gy radiation, the cells in FCGR1AshRNA group showed a significantly lowered proliferation rate and an increased apoptosis rate (P<0.05).

CONCLUSIONThe shRNA targeting IgG gene can significantly enhance the sensitivity of PC3 cells to radiation. The combination of RNA interference targeting IgG gene with radiotherapy may be more effective in the treatment of prostate cancer.

OBJECTIVETo investigate the expression of CD33⁺ HLA-DR⁻ myeloid-derived suppressor cells (MDSCs) in the peripheral blood of patients with renal carcinoma and its correlation with the clinicopathological features of renal cancer.

METHODSForty-four patients with renal carcinoma treated in our hospital between June, 2011 and October, 2012 and 18 healthy volunteers were enrolled in this study. Flow cytometry was performed to detect CD33⁺ HLA-DR⁻ MDSCs in the peripheral blood, and its correlation with the clinicopathological features of the patients were analyzed.

RESULTSThe positivity rate of CD33⁺ HLA-DR⁻ MDSCs in the peripheral blood was significantly higher in the cancer patients than in the healthy controls [(1.91 ± 0.66)% vs (0.62 ± 0.22)%, P<0.001]. The expression levels of CD33⁺ HLA-DR⁻ MDSCs in patients with renal carcinoma showed significant differences between stage I+II [(1.46 ± 0.44)%] and stage III [(2.04 ± 0.35)%] patients (P<0.01) and between stage III and stage IV patients [(2.50 ± 0.64)%] (P<0.05), but did not differ significantly in respect of age or gender.

CONCLUSIONCD33⁺ HLA-DR⁻ MDSCs expression in the peripheral blood is associated with tumor stage and differentiation in renal carcinoma and may play an important role in predicting the prognosis and tumor immunology of renal carcinoma.

Objective:To compare the clinical safety and the efficacy of the transurethral plasmakinetic bipolar enucleation of the prostate and diode laser enucleation of the prostate in day surgery patients.Methods:The clinical data of 99 patients with benign prostatic hyperplasia (BPH) who underwent day surgery in Zhujiang Hospital of Southern Medical University from August 2019 to August 2021 were retrospectively analyzed. Among them, 47 cases underwent transurethral plasmakinetic bipolar enucleation of the prostate (bipolar group), and 52 cases were treated with diode laser enucleation of the prostate (diode laser group). There were no significant differences in age [57.0(56.0, 61.0)years old vs. 59.0(57.0, 62.0)years old], prostate volume[(60.0±8.2)ml vs. (57.4±9.4)ml], preoperative total prostate-specific antigen (tPSA) [(1.8±0.9) ng/ml and (2.2±0.9) ng/ml], postvoid residual (PVR) [20.0(0, 40.0)ml vs. 20.0(1.3, 41.5)ml], maximum flow rate (Q max) [(9.4±2.6) ml/s vs. (9.6±1.9) ml/s], International Prostate Symptom Score (IPSS) [19.0(16.0, 21.0) vs. 19.0(18.0, 21.0)], quality of life (QOL) [5.0(4.0, 5.0)vs. 5.0(4.0, 5.0)] and International Index of Erectile Function 5 (IIEF-5) [(18.8±1.0) vs. (19.2±0.9)] score between the bipolar group and diode laser group (all P>0.05). The indexes of operation time, postoperative hemoglobin decline, blood sodium decline, bladder irrigation time, catheter indwelling time, Q max, IPSS, QOL, IIEF-5 score and so on were compared between the two groups. Results:All day surgeries were successfully completed without serious complications. The operation time of the bipolar group was less than that of the diode laser group [(57.3 ± 4.2) vs. (64.4 ± 6.3) min, P<0.001], and no statistically significant difference was found in the postoperative hemoglobin decline between the two groups [(9.8 ± 4.3) g/L vs. (8.5 ± 4.3) g/L, P=0.154]. None of the patients received transfusion treatment, and neither group of patients had severe hematuria or needed to be readmitted to hospital. There was no significant difference in the decrease of blood sodium [1.7 (1.3, 2.0) mmol/L vs. 1.7 (1.5, 1.9) mmol/L] and the postoperative bladder irrigation time [(7.7 ± 1.4)h vs. (8.0 ± 1.6)h] between the bipolar and diode laser groups ( P > 0.05). There were 8 patients in the bipolar group and 7 patients in the diode laser group who retained urinary catheter for 48-60 h due to intraoperative inflammatory changes in the prostate, and the remaining patients had their urinary catheter removed within 24 hours. The Q max of the bipolar group and the diode laser group one month after surgery were (20.4 ± 1.8) and (21.1 ± 1.7) ml/s, IPSS scores were 7.0 (7.0, 8.0) and 7.0 (7.0, 8.0), and QOL scores were 3.0 (3.0, 3.0) and 3.0 (2.0, 3.0), respectively. There were no significant differences in Q max, IPSS and QOL between the two groups (all P > 0.05). Conclusions:Transurethral plasmakinetic bipolar enucleation of the prostate is also feasible for day surgery, and the short-term postoperative Q max, IPSS, hemoglobin reduction and other indicators have no significant difference compared with diode laser enucleation of the prostate, and can achieve the same efficacy and safety as diode laser enucleation of prostate.

Objective To retrospectively analyze the different clinical stages of patients with prostate cancer,and to investigate it's correlation with body mass index (BMI).Methods 363 patients with prostate cancer were enrolled from January 2008 to December 2016.There were 141 cases of stage Ⅱ,Ⅲ in 20 cases,202 cases of stage Ⅳ.According to the stratification of BMI (emaciation group,normal group,overweight group,obesity group),clinical data of different groups of prostate cancer patients were compared to analyze there correlation with BMI.Results Patient's age,pre-PSA concentration,Gleason scores and PSA density were significantly correlated with clinical stage (P ＜ 0.05).Prostate volume and weight had no significant correlation with staging.There was a significant correlation between different strata of BMI and clinical stage (P ＜ 0.05).Conclusion The different strata of BMI are closely related to the clinical stage.The higher BMI,the higher risk of the prostate cancer.

OBJECTIVE[corrected] To evaluate the method and technique of single-port laparoscopic radical nephrectomy.

METHODSForm January 2009 to September 2011, 22 patients with renal carcinoma were treated with single-port laparoscopic radical nephrectomy. An incision about 5 cm in length was made through the umbilicus or in the postaxillary line under the 12th rib to establish the peritoneal or retroperitoneal working space. A single-port cannulation was deployed and the operation was carried out using standard and crooked laparoscopic equipment.

RESULTSThe operations were completed successfully in all the 22 cases without conversion to open surgery, but additional trocar was needed in 5 cases. The mean operative time of radical nephrectomy was 150 min (90-240 min). The mean postoperative hospital stay was 7.6 days (3-15 days). The operation left a roughly 5-cm-long scar in all the cases.

CONCLUSIONSingle-port laparoscopic radical nephrectomy is safe and feasible with good cosmetic effect and shows much potential in radical resection of renal carcinoma.

Prostate biopsy is the gold standard for the diagnosis of prostate cancer. Currently, both conventional transrectal and transperineal prostatic puncture is guided by rectal ultrasound, but it cannot be performed in patients with abdominoperineal resection. We treated one suspected prostate cancer patient with abdominoperineal resection and successfully performed transperineal ultrasound-guided transperineal prostate biopsy.

OBJECTIVES: To investigate the effect of progressive pre-disconnection of urethral mucosal flap during transurethral plasmakinetic enucleation of prostate (TUPEP) on early recovery of urinary continence. METHODS: Clinical data of patients with benign prostatic hyperplasia (BPH) admitted in Zhujiang Hospital of Southern Medical University during February and May 2022 were collected. All the patients underwent TUPEP, and the progressive pre-disconnection of urethral mucosal flap was performed in the procedure. The total operation time, enucleation time, postoperative bladder irrigation time and catheter indwelling time were recorded. Urinary continence was evaluated 24 h, 1 week, and 1, 3, 6 months after the removal of urinary catheter. RESULTS: All surgeries were successfully completed at one time with less intraoperative bleeding, and there were no complications such as rectal injury, bladder injury or perforation of prostate capsule. The total operation time was (62.2±6.5) min, the enucleation time was (42.8±5.2) min, the postoperative hemoglobin decrease by (9.5±4.5) g/L, the postoperative bladder irrigation time was (7.9±1.4) h, and the postoperative catheter indwelling time was 10.0 (9.2, 11.4) h. Only 2 patients (3.6%) had transient urinary incontinence within 24 h after catheter removal. No urinary incontinence occurred at 1 week, and 1, 3, 6 months after operation, and no safety pad was needed. The Qmax at 1 month after operation was 22.3 (20.6, 24.4) mL/s, international prostate symptom scores were 8.0 (7.0, 9.0), 5.0 (4.0, 6.0) and 4.0 (3.0, 4.0) at 1, 3 and 6 months after surgery, and quality of life scores at 1, 3 and 6 months after surgery were 3.0 (2.0, 3.0), 2.0 (1.0, 2.0) and 1.0 (1.0, 2.0), all of these indicators were better than those before surgery (all P<0.01). CONCLUSIONS In the treatment of BPH, the application of progressive pre-disconnection of urethral mucosal flap in TUPEP can completely remove the hyperplastic glands and promote early recovery of postoperative urinary continence with less perioperative bleeding and decreased surgical complications.
