Robotic system helps surgeons in performing surgery. Currently Da Vinci system is the most popular. Da Vinci system has been used for the stomach and bowel diseases in 27 cases(18 cases of stomach and 9 cases of colon and rectum) in the Zhongshan Hospital, Fudan University. Accurate preoperative staging is crucial, and Da Vinci system is advantageous in lymph node dissection, preservation of nerve plexus, and complete resection of mesorectum. Adoption of gastrointestinal tract reconstruction technique should depend on the operation and experience in surgery. Though Da Vinci system has limitations and the cost is high, it is believed to be the future trend.

Objective To evaluate sacral nerve stimulation (SNS) in the treatment of spastic pelvic floor syndrome (SPFS).Method In this study,36 patients of spastic pelvic floor syndrome who received SNS treatment from 2011.3 to 2011.12,were reviewed in terms of clinical curative effect,changes of anal pressure and defecography.Result After a course of SNS treatment,patients were followed up for 3 months,12 cases were cured,22 cases improved and 2 cases were ineffective,the total effective rate was 94.4%.The symptoms such as endless defecate feeling,difficulty in defecation,anal pain and anal obstruction feeling improved significantly (P <0.01 ).After the therapy,rectal anal reflex( RAR)threshold value volume rose,anal maximum contraction pressure (AMCP),anal rest perssure (ARP) decreased (P < 0.01 ).While the anal longest contraction time (ALCT)and rectal rest pressure (RRP) did not change significantly (P > 0.05 ).After treatment,when patient defecate the anorectal angle (ARA) increases,the puborectal muscle spasm notch (PMSN)attenuates (P < 0.01 ).Conclusions SNS is effective and minimally invasive in treating spastic pelvic floor syndrome.

BACKGROUND:Synthetic patch as an important substitute to pelvic tissue can replace damaged pelvic fascia tissue, and has been widely used in the pelvic floor reconstruction. OBJECTIVE:To observe the efficacy and complications of pelvic floor reconstruction with mesh, and to explore its safety and effectiveness. METHODS: Forty-five pelvic organ prolapse female patients were divided into two groups according to patient’s wilingness: experimental group, pelvic floor reconstruction with mesh (n=25); control group, transvaginal hysterectomy combined with vaginal wal repair (n=20). Perioperative conditions were recorded, and uterine prolapse staging, complications, pelvic floor function, pelvic discomfort, as wel as an objective cure rate were evaluated in the two groups during the folow-up. RESULTS AND CONCLUSION:Compared with the control group, the experimental group was characterized as shorter operative time, less amount of bleeding, milder infections, and faster recovery (AlP < 0.05). At 6 months of folow-up, the score on uterine prolapse staging was higher in the experimental group than the control group; at 12 months, the scores on pelvic floor function and pelvic discomfort as wel as the incidence of complications were significantly lower in the experimental group (P < 0.05), but the objective cure rate was higher compared with the control group (P < 0.05). These findings suggest that pelvic floor reconstruction with mesh for pelvic organ prolapsed can reduce the operative time and blood loss and promote postoperative recovery. Meanwhile, it can significantly improve pelvic floor function, pelvic discomfort, postoperative complications, the rate of exposure, and the objective cure rate, which is safe and effective during the short-term folow-up.

Objective To enrich pancreatic cancer stem cells through culturing mammospheres, and to detect the expressions of epidermal growth factor receptor(EGFR) and a disintegrin and metalloprotease 9 (ADAM9) and investigate their significance. Methods PANC1 cells were cultured in serum-free conditioned medium to continuously generate mammospheres, and parts of mammospheres were cultured on a collagen substratum to induce differentiation. Mammospheres cells and differentiated cells were collected, flow cytometry was used to detect the proportion of side population (SP) cells, and the expressions of EGFR, ADAM9 mRNA and protein were detected by real-time PCR and Western blotting. Results PANC1 cells mammospheres were successfully generated and could be passed continuously. After differentiation, mammospheres cells could regain the ability of adherent growth. The proportion SP cells in mammospheres cells and differentiated cells were ( 5.40 ± 0.38 ) % and (2.80 ± 0.42 ) %, and the difference was statistically significant ( P < 0. 05 ).Compared with differentiated cells, the expression of EGFR and ADAM9 mRNA of mammospheres cells upregulated 2.5 and 3.0 folds ( P < 0. 05 ). The expressions of EGFR and ADAM9 protein of mammospheres cells were 0.90 ± 0. 09 and 0.64 ± 0.07, which were significantly higher than those in differentiated cells (0.62 ±0.11 and 0.48 ±0.09, P <0.05). Conclusions Mammosphere cells contained higher proportion of pancreatic cancer stem cells. ADAM 9 may play an important role in the occurrence and development of pancreatic cancer through the EGFR signaling pathway.

Objective To discuss the ultrasound imaging of acardia twin before and after spontaneously blood blocked in twin reversed arterial perfusion sequence (TRAP), and to analyze the inlfuence factor for the prognosis of pump twin. Methods Seven TRAP with pump twins and acardia′s blood lfow blocked were diagnosed by US and autopsy in Hubei Women and Children′s Hospital between 2001 January to 2012 September. The ultrasound images, clinical data and pump twin’ outcome were analyzed. Results Ultrasound images showed skin edema, acardia, spine and lower limbs in seven acardia cases before blood blocked, among which 4 were acardius acephalus, 3 were acardius anceps. Single umbilical artery were detected in 7 cases with reversed umbilical artery perfusion toward fetus. Four cases had rare blood lfow (UA-PI ratio<0.7. Five acardia cases had slower growing rate than the pump twin. Ultrasound images showed no growing, no blood lfow in the acardia, the acardia twin became vagued in the second and third trimester, and ifnally developed into a paper fetus. A linear umbilical cord extend from umbilical region to placenta were found in 7 cases whose blood lfow were spontaneously blocked. Pump twin′s outcome:3 pump twins survived, 3 died in uterus, and 1 was induced labor due to hydrocephalus and cardiac failure. The most important factors that affected the prognosis of pump twin included:faster growing in acardia twin with less blood supply, abnormal brain and heart function in pump twin, chromosome abnormalities, abnormal amniotic fluid and cord entanglement. Conclusions Less blood flow and slow growth speed prompt in acardia twin suggested spontaneously acardia blood block. It is mandatory to monitor the pump twin after the spontaneous block of acardiac’s blood lfow.

OBJECTIVE:
To assess the patterns of linkage disequilibrium (LD) of 16 STR loci on X chromo- some and investigate the genetic stability.
METHODS:
Genomic DNA samples extracted from blood stains from 500 unrelated individuals and 885 lineage members from Eastern Chinese Han population were genotyped through multiplex amplification using IDtyperX-16 kit by our independent research followed by capillary electrophoresis. LD was assessed by PowerMarker v3.25 software and mutation rate of every locus was analyzed.
RESULTS:
LD were not found at the 16 X-STR loci. Allele mutations were observed at 10 loci. Among them, mutation rates of DXS6809 and DXS7132 were both up to 0.0048.
CONCLUSION
When the 16 X-STR loci included in IDtyperX-16 kit were used for parentage testing, product princi- ples can be applied to calculate the likelihood, but mutation should be taken into consideration in the case that the genotypes do not meet the genetic law (especially at DXS6809 and DXS7132).

Objective To study the effect of balloon dilatation therapy on dysphagia caused by cricopharyn- geal achalasia.Methods Ten cases of dysphagia were diagnosed as cricopharyngeal achalasia by videofluoroscopic swallowing study(VFSS).A 14~* urethral catheter was inserted into the esophagus and an amount of water was injec- ted into the balloon of the urethral catheter to make it turgid.Then the catheter was pulled upwards and passed through the stricture of esophagus to dilatate the cricopbarygeus muscle.Meanwhile,low frequency electrical stimula- tion was used and combined with functional training of the organs related to deglutition and ingestion.The results be- fore and after the treatment were evaluated.Results After 19.7 times of dilatation therapy,the content of water in- jected into the balloon was increased from 2.65?0.91 ml to 8.20?0.92 ml.Cricopharyngeal achalasia was alle- viated significantly(P
