Objective To investigate the impact of workplace bullying,general self?efficacy,self?es?teem on mental health of nurses. Methods With random sampling,450 nurses from six hospitals in Nanning of Guangxi were selected to complete questionnaire survey. Results 34.7% of nurses were reported to have been subjected to bullying at their workplace. Workplace bullying(23.78±6.94) showed significantly nega?tive relationship with mental health(36.63±4.53)( r=-0.32, P<0.01),while general self?efficacy(26.86± 4.82) and self?esteem(30.62±4.08) showed significantly positive correlations with mental health( r=0.45, 0.44, P<0.01). Workplace bullying had a significantly negative effect on mental health ( β=-0.25, P<0.01) ,and the relationship was affected by general self?efficacy and self?esteem. Conclusion Workplace bullying can influent nurses' mental health through self?esteem and the relationship is moderated by general self?efficacy.

Objective: To confirm whether Biejiajian Pill has the action of promoting blood circulation to remove blood stasis, softening the hard lumps and dispelling the nodes. Methods: The blood stasis model, anti tumor model, the model of collagen and urinary hydroxyproline evacuating from fibrous liver of rat and the other pharmacological models were prepared to confirm the action of the pill. Results: (1) This pill has the absorption of erythrocyte and blood clot of itself. (2) After the pill being given to the rats with cirrhosis, the hepatitisfibrils decreased, the excretion of urinary hydroxyproline increased and the content of collagen of the therapeutics group was less than the control group. All of those suggested that this drug has the action of promoting the degradation of the collagen fiber and reabsorption of the hepatitis collagen. (3) This pill can apparently inhibit the proliferation of S 180 . Conclusion: The drug has the action of promoting blood circulation to remove blood stasis, softening the hard lumps and dispel the nodes.

Objective To summarize the experience in hepatic artery reconstruction in adult-to-adult living donor liver transplantation(ALDLT).Methods Fifty patients underwent ALDLT in our hospital from January 2002 to July 2006.All the hepatic a~ery reconstructions were done under surgical microscope.ResultsTwo patients(4%)presented with hepatic artery thrombosis.All the patients were followed up for 2 to 52 months (median,9 months),and no hepatic artery stenosis nor hepatic artery pseudoaneurysm occurred.The 1-year survival rate was 92%(46/50).Conclusions Systematic evaluation of hepatic artery reconstruction and use of microsurgical technique are key to the reduction of complications of hepatic artery reconstruction in ALDLT.

Objective To summarize the experience in application of da Vinci robotic surgical system in radical resection of rectal cancer,and investigate the proper position of trocars and operative techniques.Methods The clinical data of 13 patients who received radical resection of rectal cancer accomplished by the da Vinci robotic surgical system at the Southwest Hospital from February 2010 to February 2011 were retrospectively analyzed.The patients were in lithotomy position and received combined intravenous anesthesia.Five or 4 trocars were used.Miles procedures were performed on patients with lower tumor position,and the other patients received Dixon procedure.Results The operation was successfully performed on all patients.Five trocars were selected for the first 3 patients,and 4 trocars for the other 10 patients.Nine Dixon procedures and 4 Miles procedures were selected.The mean operation time was 217.3 minutes (range,160-260 minutes).The mean operative blood loss was 53.3 ml (range,40-70 ml) in Dixon procedure and 120.0 ml (range,90-130 ml) in the Miles procedure,and no blood transfusion was needed.The mean number of lymph nodes dissected was 13.9 (range,8-21 ),and the time to bowel movement was 3.2 days (range,2-5 days).Two patients were complicated with pulmonary infection,1 with urinary tract infection,and they were cured by antimicrobial therapy.No other morbidity or mortality was found.The results of postoperative pathological examination showed that there were no residual cancer cells at the resection margin,and the distance between the resection margin and the tumor was 6.3 cm (range,3-10 cm).There were 1 patient in stage Ⅰ,5 in stage Ⅱ and 7 in stage Ⅲ.The mean time of follow-up was 5.9 months (range,3-12 months),and no recurrence or metastasis was found during follow-up.ConclusionsRadical resection of rectal cancer with da Vinci robotic surgical system utilizing 4 trocars has the advantages of minimally invasive surgery with fast recovery as well as the ease of dissection afforded by the surgical robot.

Objective To summarize the experiences in laparoscopic inguinal hernia repairing for adult patients. Methods Clinical data of 512 hernia cases admitted in our center from March 2007 to Sep 2010 were retrospectively analyzed.There were 437 cases of single-sided hernia,including 281 indirect inguinal hernia,86 direct inguinal hernia,15 femoral hernia,16 combined inguinal hernia and 39 recurrent hernia.There were also 75 cases of double-sided inguinal hernia,including 3 recurrent hernia.There were 41 acute incarcerated hernia cases.The average postoperative follow up time was(29 ± 12) months. Results 507 cases underwent successful laparoscopic repair,and 5 cases were converted to open procedure.There were 238 TAPP and 269 TEP in laparoscopic operations.The average operative time for TAPP was (69 ±19) min,and (58 ±15) min for TEP.The average length of postoperative stay was (5.0 ± 1.5) days.The percentage of resuming normal activity after 2 weeks and 4 weeks were 95.7％ (485/507) and 99.0％(502/507).The most common postoperative complications were seroma (9.7％,49/507),transient paresthesia (4.1％,21/507) and chronic pain (0.8％,4/507).The recurrence rate was 0.6％ (3/507).Conclusions Laparoscopic repair of inguinal hernia has the advantage of less trauma,faster recovery,and lower recurrence rate.

With the development of instrumentation and surgical techniques,laparoscopic gastrectomy has become a promising surgical option for the treatment of gastric cancer.While laparoscopic gastrectomy is high technique-demanding,which hampered its popularization.Compared with traditional laparoscopes,Da Vinci surgical system has more special features,such as flexible robotic arms and three-dimensional imaging,which facilitates surgical procedures.A 58-year-old male patient with gastric cancer underwent Da Vinci surgical system-assisted radical total gastrectomy at the Southwest Hospital in March 2010.The mean operation time and blood loss were 270 minutes and 60 ml,respectively,and the number of dissected lymph nodes was 21.The short-term clinical effect was perfect without postoperative complications.Da Vinci surgical system-assisted radical total gastrectomy is safe and feasible,and it brings challenges to conventional laparoscopes.

Objective To determine the value of helical computed tomography (HCT) and color doppler flowing imaging (CDPI) in evaluating the resectability of pancreatic cancer. Methods The clinical data of 114 patients with pancreatic cancer who had been admitted to the Affiliated Hospital of North Sichuan Medical College from January 1995 to December 2002 were retrospectively analyzed. The values of HCT and CDPI in assessing the resectability of pancreatic cancer were determined according to the results of operation and pathological examina-tion. All the data were analyzed by chi-square test and Fisher exact probability. Results Of all patients, 109 were examined by HCT, 97 by CDPI and 96 by HCT+CDPI. For patients examined by HCT, the resection rates of pancreatic head cancer, pancreatic body and tail cancer and total pancreatic cancer were 45.3% (39/86), 26.3% (5/19) and 0 (0/9), respectively. The resection rate of pancreatic head cancer was higher than that of pancreatic body and tail cancer (χ2=8.965, P<0.05). With the increase of tumor size, the invasion rate and metastasis rate were increased and the resection rate was decreased (z=6.15, 5.35, 7.18, P<0.01). The sensitivity rate and specificity rate were 77.8% and 82.2% of HCT, 73.3% and 80.6% of CDPI, 90.6% and 92.4% of HCT+CDPI in assessing the resectability of pancreatic cancer. The values of Kappa identity test of HCT, CDPI and HCT+CDPI were 0.58, 0.52 and 0.82, respectively. Conclusions Combined application of HCT and CDPI can further improve the accuracy in assessing the resectability of pancreatic cancer.
