Objective To investigate the relationship between inducible nitric oxide synthase(iNOS)mRNA expression of pancreatic tissues and intestinal permeability,and the effect of salviae miltiorrhizae on the change in gut permeability in rats with severe acute pancreatitis(SAP).Methods All rats were randomly divided into three groups:Sham operation(group C,n=15),SAP group(group SAP,n=15),and salviae miltiorrhizae therapeutic group(group T,n=15).At 24h After operation,the iNOSmRNA expressions of pancreas were determined by in situ hybridization(ISH),and blood amylase(AMY),nitric oxide(NO) and lipopolysaccharide(LPS) were examined.The histopathologic changes of pancreas and ileum were observed.Intestinal permeability was measured by means of albumin clearance(AC)of 125I-labeled rat serum albumin.Results The iNOSmRNA expressions of pancreas in group SAP were markedly increased in comparison with group T(P

Objective To explore the influence of hospital- based transitional care on the rehabilita-tion of patients with enterostomy, and provide evidence- based reference for specialist care of the enterostomy patients. Methods The randomized controlled trials on the hospital- based transitional care in enterostomy patients were collected by computer using China National Knowledge Infrastructure Database, Chinese Science Technology Periodical Database, Wanfang Periodical Database, Foreign Medical Information Resources Database and PubMed from the building of the database till December 2014, and analyzed by RevMan 5.2 software. Results Sixteen articles were included in the study, involving 1 263 patients with enterostomy. The results of Meta- analysis revealed that the incidence of complications in transitional care patients was lower than that in conventional discharge guidance patients, odds ratio(95% confidence interval) was 0.31 (0.21-0.45), the difference was significant (Z=6.02, P<0.01), and the quality of life was raised (including the physical function, cognitive function, role function, emotional functions, social function and the total quality of life), weighted mean differences (95% confidence interval) were 13.81 (8.23-19.39), 22.00 (17.21-26.79), 15.22(11.71-18.73), 16.68(13.01-20.35), 22.60(16.58-28.62), 17.46(13.53-21.38),the differences were significant(P<0.01). Conclusions The transitional care model giving priority to hospital service resources can provide a higher level professional care for patients after enterostomy, and avoid or reduce the complications, promote the recovery earlier as well as constantly improve the quality of life.

Objective To investigate the distribution and antibiotic resistance of clinical isolates in People’s Hospital of Qingyang during 2014 to provide evidence for rational antimicrobial therapy.Methods Bacterial strains were isolated and identified by routine methods and tested by disk diffusion method and E-test for antimicrobial susceptibility. The data were analyzed according to CLSI breakpoints using WHONET 5.6 software.Results Of the 2 121 nonduplicate strains isolated from January through December 2014, 1 565 (73.8%) were gram-negative and 556 (26.2%) were gram-positive strains. The top ifve pathogens wereE. coli, K. pneumoniae, A. baumannii, S. aureusand P. aeruginosa. The prevalence of methicillin-resistantStaphylococcus aureus (MRSA) and methicillin-resistant coagulase negativeStaphylococcus (MRCNS) was 44.6% and 15.4%, respectively.E. coli was the most common gram-negative bacterial species, whileS. aureus was the most common gram-positive bacteria species. Gram-positive bacteria were still highly susceptible to vancomycin, and gram-negative bacteria (such as Enterobacteriaceae) were still highly susceptible to carbapenems.ConclusionsE. coli is the most prevalent pathogen isolated from inpatients in this hospital during 2014. The prevalence of ESBLs-producing strains is the highest inE. coli isolates. The pathogenic bacteria in this hospital showed increasing resistance to a variety of antibacterial agents. Surveillance of antibiotic resistance and effective control measures are necessary to control the growing antimicrobial resistance.

Objective To explore the value of Artis zeego robot imaging system endoscopic retrograde cholangiopancreatography (ERCP) for biliary calculi. Methods ERCP was performed on 12 patients with biliary tract dilation, diagnosed by B ultrasonography. Artis zeego robot was used simultaneously to acquire 3D images and biliary system reconstruction. The diagnostic consistency was assessed based on endoscopy and surgery if necessary. Results 3D rotating acquisition and biliary reconstruction were performed in the 12 patients. All diagnosis coincided with those of surgery and ERCP findings, achieving a consistency rate of 100%. Patients with extrahepatic bile duct stones of uncertain number (n = 2), with suspected biliary duct calculi ( n = 1 ) and with suspected intrahepatic bile duct stones ( n = 2) under ERCP were all diagnosed by the robot imaging system. Conclusion During ERCP, 3D rotating image acquisition and biliary reconstruction with Artis zeego robot is helpful for precise diagnosis of biliary tract stones.

BACKGROUND: Because of the specificity and complexity of hepatic portal, carcinoma of bile duct of the hepatic portal is a difficulty in the surgical treatment. OBJECTIVE: To evaluate the safety and feasibility of simultaneous pancreaticoduodenectomy and liver transplantation for the end-stage hilar cholangiocarcinoma. RESULTS AND CONCLUSION: Pathology demonstrated a middle or low differentiation of hilar cholangiocarcinoma, and left, right hepatic duct, together with lobus quadratus were invaded. The tumor metastasized to hilar and posterior pancreatic lymphonodes, without involving the head of pancreas, duodenum and stomach. The function of transplanted liver recovered smoothly, and the endocrine and exocrine functions of pancreas were kept well. CA19-9 dropped to the normal levels. The patient recovered and discharged at 1 month after surgery, and still survived after one year follow up. These suggest that simultaneous pancreaticoduodenectomy and liver transplantation as a treatment of hilar cholangiocarcinoma are safe and feasible.

Objective:To determine the safety of prophylactic irradiation dose CTV 60Gy optimized to CTV 50Gy for II b region in patients with stage N 0-N 1 nasopharyngeal carcinoma (NPC) and the dose advantage and clinical value for parotid gland protection, and to understand the diagnostic value of PET-CT and diffusion-weighted imaging (DWI) for suspicious positive lymph nodes in the neck (5 mm≤maximum short diameter<10 mm). Methods:Clinical data of 157 patients with primary non-metastatic NPC (N 0-N 1) admitted to our hospital from June 2015 to March 2017 were retrospectively analyzed. 104 patients underwent II b clinical target volume optimization guided by multimodal imaging system. Survival analysis was performed by Kaplan - Meier method. Univariate/multivariate regression analysis was performed to analyze the pattern of cervical lymph node recurrence. Paired t-test was used to compare the differences in target volume and parotid gland dose parameters before and after dose optimization. Results:Sixty patients underwent single-neck optimization in stage N 1, 25 patients received double-neck optimization (only those with retropharyngeal lymph node metastasis), and 19 patients underwent double-neck optimization in stage N 0. Three patients had cervical regional recurrence, all in-field. The 5-year overall survival rate was 93.3%. The lymph node recurrence-free survival rate, local recurrence-free survival rate, distant metastasis-free survival rate and disease-free survival rate were 97.1%, 91.3%, 88.5% and 80.8%, respectively. Cervical lymph node recurrence was associated with local recurrence in the nasopharynx, regardless of retropharyngeal lymph node status. Fourteen patients had suspicious positive cervical lymph nodes in II b region, with a mean maximum short diameter of 7.1 (5~9) mm on the largest cross-sectional plane, and 11 of them were positive on PET-CT, with a mean SUV max of 2.96 (2.5~3.3). There was no significant difference in GTV after optimization ( P>0.05). D mean, D max, D 50% and V 26Gy of parotid gland were significantly lower than those of conventional plan (all P<0.01). Conclusions:It is safe to optimize CTV 60Gy to CTV 50Gy in II b region in patients with N 0-N 1 NPC, and the exposure dose to normal tissues around the parotid gland and neck is significantly reduced. For small lymph nodes that do not meet the diagnostic criteria, it needs to be individualized in combination with multimodality imaging systems, such as PET-CT and DWI.

Objective:To study the clinical efficacy of laparoscopic radical cholecystectomy in the treatment of stage Ⅲ gallbladder cancer.Methods:The clinical characteristics and postoperative follow-up data of 184 patients (male 66, and female 118) who underwent radical cholecystectomy for stage Ⅲ gallbladder cancer at Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, from May 2015 to May 2022, were retrospectively analyzed. The age was (67.0±8.6) years old (range 38 to 85 years old). There were 71 patients in the laparoscopic group and 113 in the open group. The general medical data, surgery-related indicators and complications were analyzed. Follow-up was completed by outpatient visits and by telephone.Results:The laparoscopic group showed better postoperative alanine aminotransferase [67.5 (40.0, 138.5) vs. 104.0 (45.0, 252.2) U/L] and aspartate aminotransferase [41.5 (26.0, 71.2) vs. 53.0 (30.2, 153.5) U/L] recovery, higher albumin levels [32.05 (30.18, 35.20) vs. 30.50 (27.70, 33.50) g/L], earlier abdominal drainage tube removal [8.00(6.00, 10.25) vs. 10.00(6.00, 13.00)d], shorter hospital stay [10.00(8.00, 15.25) vs. 14.00(9.00, 19.00) d] and lower incidences of complications [(14.1%(10/71) vs. 31.9%(36/113)] when compared with the open group (all P<0.05). The 1 year (49.1% vs 61.0%), 2 years (24.0% vs. 28.5%), 3 years (16.0% vs. 14.5%) overall survival ( P=0.640), and the 3 years progression-free survival (18.3% vs. 15.0%, P=0.463) showed no significant difference between the 2 groups. Conclusion:Laparoscopic surgery for AJCC TNM stage Ⅲ gallbladder cancer showed comparable results with open surgery. When compared with open surgery, laparoscopic radical resection of gallbladder cancer had the advantages of earlier removal of abdominal drainage tube, lower incidence of postoperative complications, and shorter hospital stay.

Objective:To study the effect of preoperative transcatheter arterial chemoembolization (TACE) on postoperative complications after hepatectomy in patients with hepatocellular carcinoma (HCC) by propensity score matching analysis.Methods:Of 1 666 patients with HCC undergoing hepatectomy in Tongji Hospital, Tongji Medical College of Huazhong University of Science and Technology and Tianyou Hospital of Wuhan University of Science and Technology from March 2015 to March 2021 were retrospectively screened. Of 262 patients were enrolled, including 236 males and 26 females, aged (50.3±11.8) years. Of 131 patients were enrolled in both the single surgery group and the combined group (preoperative TACE + surgical resection). Factors affecting the complications after hepatectomy in patients with HCC were analyzed using univariate and multivariate logistic regression method.Results:After matching the propensity score, the incidence of postoperative complications in the single surgery group was 22.1% (29/131), lower than that in the combined group [41.2% (54/131), χ 2=11.02, P<0.001]. The incidence of bile leakage in the single surgery group [2.3% (3/131)] was also lower than that in the combined group [(9.2% (12/131), χ 2=5.73, P=0.017]. Multivariate logistic regression analysis showed that the combined group ( OR=2.43, 95% CI: 1.28-4.61, P=0.007) had an increased incidence of postoperative complications, so did patients with a preoperative alpha-fetoprotein > 400 μg/L, anatomic hepatectomy, long operation time, and hilar occlusion. Conclusion:Preoperative TACE could be a risk factor for postoperative complications in patients with HCC, especially for the postoperative biliary leakage.
