Objective For benign or tumor of borderline malignancy in the distal pancreas,a spleen-preserving distal pancreatectomy can be carried out.This study aimed to assess the safety and feasibility of this operation.Methods Between June 2009 and March 2012,7 patients underwent laparoscopic distal pancreatectomy assisted by the da Vinci Robotic System (RDP) for benign or pancreatic tumor with borderline malignancy.The clinical data were analyzed.Results Robotic-assisted spleen-preserving laparoscopic distal pancreatectomy was successfully carried out in 6 patients,with robotic assisted splenectomy and distal pancreatectomy on the remaining patient.Among them,to the 6 patients with distal pancreatectomy,one patient received right adrenal tumor resection and another patient received cholecystectomy.The average operation time was 368 minutes,and the blood loss was 200 ml.One patient developed postoperative bleeding,and was treated conservatively with hemostatic drugs (grade Ⅱ).There was no conversion to laparotomy.According to the international pancreatic fistula research team's classification of postoperative pancreatic fistula,1 patients were diagnosed to have pancreatic fistula (grade A).The mean postoperative hospital stay was 8.7 days.There were no other complications.Conclusions Robotic-assisted spleen-preserving laparoscopic distal pancreatectomy was safe and feasible.The Kimura operation was used in spleen-preserving operations because its 3D visual field and stability in control helped to preserve splenic blood supply and reduced the chance of postoperative regional portal hypertension.

Objective To probe the prevention and management of complications after laparoscopic cholecystectomy (LC). Methods Retrospective study was performed on 13 000 patients, who underwent LCs from September 1991 to February 2005 at our department. Results The complication rate was 1. 66% (216 patients) including intraabdominal hemorrhage in 21 patients (0. 16%),bile duct injury in 11 (0. 08% ),gastrointestinal perforation in 7(0. 05% ) , bile leakage in 26(0. 20% ) , retained abdominal tumor in 10(0. 08% ) , retained common bile duct stones in 47(0. 36% ) , intraabdominal abscess in 4(0. 03% ) , upper gastrointestinal hemorrhage in 2(0. 02% ) , extensive subcutaneous emphysema in 32 (0. 25% ) , port wound infection in 46(0. 35% ) , incisional hernia in 1 (0. 01% ) and deep vein thrombosis in 9 (0.07%). Six patients died postoperatively. Conclusions LC is a safe technique when up-to-date equipment and meticulous dissection techniques are employed. With the routine procedure, LC can be performed more safely.

Objective To evaluate the effects of sevoflurane on right ventricular systolic function after cardiopulmonary bypass in patients undergoing coronary artery bypass grafting(CABG). Methods Eighteen patients with coronary heart disease,13 males,5 females,ASA Ⅱ or Ⅲ,aged 50-80 years,measuring 1 50-182 cm in height,weighing 5 1-96 kg,scheduled for CABG under CPB were enrolled in this study.Anesthesia was maintained with intravenous anesthesia, and 1 MAC sevoflurane inhalation lasted for 60 min after CPB.Hemodynamic indicators such as HR,MAP, CVP,cardiac output (CO),Systemic vascular resistance (SVR)and right ventricular parameters in-cluding tricuspid annular plane systolic excursion (TAPSE)and velocity (TAPSV)were recorded be-fore sternotomy (T2 ),30 min after CPB (T3 ),60 min after CPB (T4 ).Results Compared with T1 , CO was increased at T2 (P <0.05);compared with T2 ,CO was decreased at T3 and T4 (P <0.05 or P <0.01),with a statistical significance;compared with T1 ,TAPSE and TAPSV were increased at T2 (P <0.05 or P <0.01);compared with T2 ,TAPSE and TAPSV were decreased at T3 and T4 (P<0.05);with a statistical significance in TAPSE and TAPSV.Conclusion For the patients undergo-ing CABG under CPB,1 MAC sevoflurane inhalation after CPB can reduce right ventricular systolic function,which,however,is within the normal ranges.

Objective To report a randomized trial in comparing the clinical outcomes of three-port LC versus standard four-port LC. Methods From March 2001 to August 2004, four hundred consecutive patients who underwent elective LC were randomized to receive either the three-port or the four-port technique. All patients were blinded to the type of operation they underwent. Postoperative overall pain and incisional pain at different sites were assessed on the first day after surgery using the Prince-Henry scale. Other outcome measures included length and success of the operation, analgesia requirements, postoperative complications, postoperative stay, and the cosmetic results. Results There was no difference between the two groups in age, sex, weight or other diseases. In terms of outcome, patients in the three-port group had less pain at individual subcostal port sites and better cosmetic results. Success rate, mean operative time, complications, subxiphoid port and overall pain score, analgesia requirements, and postoperative hospital stay were similar between these two groups. Conclusion Three-port LC resulted in less individual port-site pain and similar clinical outcomes but fewer surgical scars compared to four-port LC. The three-port technique is as safe as the standard four-port procedure for LC. Thus, it can be recommended as a routine procedure in elective LC.

Objective:To describe the epidemiological characteristics of mental disorders in Ximeng Wa Au-tonomous County and explore psychosocial risk factors of mental disorders. Methods:Two thousand three hundred and eighty one residents aged 1 8 years and over were sampled using multistage sampling in Ximeng Wa Autono-mous County in 2013. All respondents were investigated by face-to-face interview. Mental disorders were screened out by using the General Health Questionnaire (GHQ)and diagnosed according to the International Classification of Diseases Checklist (ICD-10-Checklist)criteria. Results:Life time prevalence of any mental disorder was 19. 86%(419/2110). The lifetime prevalence rates of substance use disorder,anxiety disorder,insomnia,mood disorder, schizophrenia were 12. 99%(274/2110),6. 30%(133/2110),2. 94%(62/2110),2. 32%(49/2110)and 1. 00%(21/2110)respectively. Male (OR=0. 43),older age (35 -49 years,OR=1. 78;50 -64 years,OR=2. 59;≥65 years,OR=3. 5 1 ),unmarried and other marital status (OR=0. 3 1 ),non-Wa and non-Lahu ethnic groups (OR=0. 29)were associated with neurotic,stress-related and somatoform disorders. Male (OR=2. 41),older age (35 -49 years,OR=2. 29;50-64 years,OR=3. 20;≥65 years,OR=4. 58),non-farmer and non-self-employed occupation (OR=0. 41),and non-Wa and non-Lahu ethnic groups (OR=0. 32)were associated with psychoactive substance use disorder. Male (OR =0. 35 ) and order age (≥65 years,OR =3. 05 ) were associated with mood disorders. Conclusion:Lifetime prevalence of any mental disorder,substance use disorders and anxiety disorders are high in Ximeng Wa Autonomous County. Measures should be strengthened against prevalence of mental disorders in ethnic minority areas.

Objective To investigate the epidemiological characteristics of nosocomial fungal infections in severe sepsis patients and analyze the influencing factors by logistic regression.Methods The clinical data of 578 patients with severe sepsis admitted to our hospital from January 2008 to January 2016 were retrospectively analyzed.The epidemiological characteristics were investigated.The possible influencing factors of nosocomial fungal infection were analyzed by univariate analysis and multivariate logistic regression analysis.Results Among 578 cases of severe sepsis,215 cases were accompanied by nosocomial fungal infection (infection rate 37.20％).The infection sites were mostly lungs and the fungal types were Candida albicans.The prognosis of the patients was poor.The survival time was less than 90 days,accounting for 42.33％ (91/215).There were significant differences in age,length of stay in intensive care unit (ICU),duration of more than two antibiotics,use of ventilators,hormones,invasive procedures,acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score between the infected group and the uninfected group (P ＜ 0.05).The danger degree from high to low of the risk factors were ICU stay ≥ 100 h (OR =5.697),use respirator (OR =5.388),invasive operation (OR =4.987),age ≥65 years (OR =4.584),and continuous use of two antibiotics ＞ 7 d (OR =3.287),use steroid (OR =2.141).Conclusions Severe sepsis with hospital acquired fungal infection is more common in the lung,and most of them are Candida albicans infection,with poor prognosis and high mortality.ICU stay ≥ 100 h,use respirator and steroid,invasive operation,age ≥65 years,and continuous use of two antibiotics ＞ 7d are risk factors.Specific preventive measures should be taken to reduce fungal infections.

To analyze and evaluate the knowledge of Chinese Guidelines of Diabetes Prevention and Treatment in Shanghai medical staff. 175 medical staff working in endocrinology or community health were enrolled and evaluated by a questionnaire of guidelines about the state of professional, training, and related knowledge. Only 16. 6% medical staffwere trained about the guidelines( 46. 67% from the general hospitals, 14. 75% from secod-level hospital and 7. 14% persons from the community hospitals, P＜0. 01 ). The total correct answer rate of the guidelines was 37. 36%. The correct rate of community hospitals was lower than others( P＜0. 05 ). The rate of doctors' was higher than nurses'( P＜0. 05 ). There were difference between doctors and nurses with the key point of diabetes care knowledge in different level hospitals. The effective method of clinical training in diabetes care should be explored. We still have to work hard to promote the effect of diabetes control and prevention. Effective training about the guidelines should be enhanced. The cooperation between general hospitals and community health institutions in diabetes prevention and treatment should be enhanced.
