The single needle method for urethrovesical anastomosis with strengthened posterior fixation during laparoscopic radical prostatectomy was explored. The method was initiated by performing a fixing suture with a knot at 4 o'clock of the posterior lip of bladder neck, and another suture at nearby position was performed to leave the knot outside. From 5 o'clock to 8 o'clock, sutures were performed every one o'clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were performed every 3 sutures. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. After completing the full circumference, the needle was drawn near the 4 o'clock and tied at the tail end. Any leakage could be closed with additional interrupted sutures. The clinical data of 89 patients who underwent this method were retrospectively compared with those of 23 patients who underwent the single knot method. The results showed that the anastomosis, operative and catheterization time was 17.6+/-4.7 min, 134.0+/-10.7 min and 6.5+1.6 days respectively. There were 3 temporal urinary leakages identified in 89 cases requiring prolonged catheterization. No urinary leak and anastomotic stricture was confirmed, and 95.2% patients had total urinary control. It was concluded that this method was simple and safe for urethrovesical anastomosis.

Objective To describe the single needle running suture method for the urethrovesi-cal anastomosis during laparoscopic radical prostatectomy(LRP). Methods Forty-five patients of prostate cancer underwent LRP with the single needle running suture method. The technique was initi-ated by performing a fixing suture at the posterior lip of bladder neck at 4 o' clock and tying the first knot. Another suture at the nearby position of the first suture was performed to leave the first knot outside. From 5 o' clock to 8 o' clock, sutures were performed every one o' clock to secure posterior approximation, then every two o'clock a suture. To avoid a loose anastomosis, lock sutures were per-formed every 3 sutures. After completing the full circumference, the needle was drawn at the 2 o' clock for the second knot. The needle was always driven full-thickness outside-in in the bladder neck and inside-out on the urethra. Any remaining leakage could be closed with additional interrupted su-tures. Results All urethrovesical anastomosis were completed successfully. The mean anastomosis time was 16 rain(from 12 to 25 min), and mean operative time was 132 rain (112 to 185 rain). The mean catheterization time was 9 d(7 to 14 d). Three temporal urinary leaks requiring prolonged cathe-terization were identified. Forty-four patients had total urinary control in 1 year postoperatively and no other short-term or persistent complication was found with a mean follow-up of 21 months. Conclu- sion The single needle running suture method could be a simple and safe method for urethrovesical anastomosis during LRP.

Objective To evaluate the clinical value of ultrasonography guided percutaneous core needle biopsy in pancreatic lesions. Methods Thirty-four patients with 36 pancreatic lesions in Shanghai First People′s Hospital Afifliated to Shanghai Jiao Tong University from February 2012 to November 2013 underwent conventional ultrasound-guided percutaneous core needle biopsy using automatic gun and 18-gauge biopsy needles. The site, size, internal and surrounding vascularity, the sampling number of the lesions, and whether the specimens′ quality was satisfied were recorded. Then specimens were sent for pathological examination, and all above observations were compared with the ifnal diagnosis. Results The number of lesions with 2, 3 and 4 samplings was 32, 2 and 2, respectively. The average number of sampling was 2.2 (mean, 2.17;standard deviation, 0.51) and the acquisition rate of satisifed specimens was 89%(32/36). The pathological results of biopsy were malignant in 31 of 36 lesions including 27 cases of ductal adenocarcinoma, 2 cases of lymphoma, 1 case of small cell neuroendocrine carcinoma and 1 case of uterine leiomyosarcoma metastasis. The other 5 lesions were non-malignant including 3 cases of benign lesion, 1 cases of atypical hyperplasia and 1 cases of granulation tissue. The 36 lesions were ifnally diagnosed as 34 cases of pancreatic malignancy, 2 cases of non-malignant neoplasm. The sensitivity, speciifcity, accuracy, positive predictive value and negative predictive value of ultrasonography guided percutaneous core needle biopsy in pancreatic lesions were 91%(31/34), 100%(2/2), 92%(33/36), 100%(31/31) and 40%(2/5), respectively. Youden index was 0.91. Two patients had mild upper abdominal pain and 1 patient had transient elevated serum amylase. No pancreatitis, pancreatic fistula, peritonitis, bleeding or dispersion of malignant cells along the penetrating channel or other serious complications occurred. Conclusion Ultrasonography guided percutaneous core needle biopsy is a simple, rapid, safe and effective diagnostic method in pancreatic lesions with high clinical value.

Objective To study the biodistribution of anti-HER-2/neu monoclonal antibody Herceptin labeled by 131I(131I-Herceptin) in healthy KM mice and nude mice bearing human ovarian cancer xenografts and radioimmunoimaging (RII) of the nude xenografts-bearing mice.Methods 131I-Herceptin was prepared using Iodogen method.The labeling efficiency, radiochemical purity, stability and immunocompetence were measured.The percentage activity of injection dose per gram of tissue (%ID/g) and the radioactivity ratio of tumor to non-tumor tissue (T/NT) were calculated for each time point.The optimal time for imaging was investigated by comparing the 131I-Herceptin SPECT for the nude mouse models bearing ovarian cancer xenografts at different time points.Results The labeling efficiency and radiochemical purity of 131I-Herceptin were 89.8% and 98.4%, respectively.The labeling was stable and had good immunocompetence.131 I-Herceptin was cleared rapidly mainly through liver, spleen and kidneys, consistent with first order two-compartment model.The uptake of 131I-Herceptin in the tumors bearing human SKOV-3 xenografts was much higher than that in nontumor tissue.The% ID/g was 18.08 in the tumor at 24 h post injection.The T/NT ratio increased with time and was 27.27 at 72 h post injection.The tumors in nude mice bearing SKOV-3 xenografts could be visualized on 131I-Herceptin SPECT imaging 2 h post injection; definitely identiffed 48 h post injection and the radioactivity ratio of tumor to contralateral tissue was 11.44 at 120 h post injection.However, the tumor in nude mice bearing HO-8910 xenografts did not show abnormal uptake of 131 I-Herceptin at each time point.Conclusions 131 I-Herceptin is a good radiopharmaceutical targeting SK-OV-3 xeuografts and it may be useful in imaging carcinoma of ovary and target therapy of its metastases with high HER-2/neu expression.

Objective To develop and evaluate a porcine model for training the single needle running suture method of laparoscopie urethrovesical anastomosis(LUA). Methods Twenty minipigs with mean weight of 30kg were general anaesthetized with Sumianxin solution 0. 1 ml/kg intramuscularly. Pneumoperitoneum was created by insufflation of carbon dioxide by a veress needle inserted through the umbilicus. One 10mm port and two 5mm ports were positioned after the establishment of pneumoperitoneum. The intestine was used as "bladder". The procedures were completed with the single needle running suture method of laparoscopic urethrovesical anastomosis. Six trainees performed the LUA procedure based on the models during a laparoscopic training course, following the technique used in the operation room. The learning curve was analyzed by operative time. Results The porcine model for laparoscopic training was established successfully and 3 LUAs could be performed on each pig. Each trainee performed 10 LUAs based on the models during the training course of laparoscopic urology. The operative time declined from (55.3±10. 4)min initially to (22.4±4.8)min (P＜0. 01) after the training course. At the end of training, all trainees could accomplish a watertight LUR procedure on the model. Conclusions The establishment of the training model is feasible. The trainees could acquire the skills necessary to perform LUA in vivo based on this model. The model provides a platform for training the basic techniques of LUA procedures.

OBJECTIVETo investigate the expression of microRNA-100 (miR-100) in human gastric cancer cells and its role of miR-100 in migration, invasion and proliferation in gastric cancer cell line SGC7901.

METHODSTotal RNAs were extracted from formalin-fixed and paraffin-embedded tissue samples of SGC7901 cells, gastric cancer (50 cases), non-tumor (18 cases) and lymph nodes with metastases (18 cases). The expression of miR-100 was examined by reverse transcription (RT)-qPCR. Additionally, SGC7901 cells were transfected with Pre-miR-100 and negative control constructs, and then their ability of migration, invasion and proliferation in vitro was documented after 48 hours.

RESULTSRT-qPCR showed that although miR-100 expressed in all samples, compared to non-tumour tissues, the expression was lower both in SGC7901 cells and gastric cancer tissues (P = 0.0077, P < 0.01). SGC7901 cells and primary gastric cancer tissues with lymph nodes metastasis had lower miR-100 expression than those of without lymph node metastasis (P = 0.0361, P = 0.0356). The migration ability and invasion of SGC7901 cells transfeced with pre-miR-100 decreased as compared with control cells (P = 0.0025, P = 0.0028 respectively). However, miR-100 expression had no significant effects on the cell proliferation.

CONCLUSIONSExpression of miR-100 inhibits the migration and invasion of gastric cancer cells without significant alteration of proliferation. Therefore, miR-100 may play an inhibitory role in the progression of gastric carcinoma.
