Objective To investigate the surgical management of Crohn's disease complicated with duodenal fistula.Methods The clinical data of 1 012 patients with Crohn's disease who were admitted to the Nanjing General Hospital of Nanjing Military Connnand from January 2002 to January 2014 were retrospectively analyzed.Of the 1 012 patients,22 were complicated with duodenal fistula,including 12 with ileocolonic anastomosis-duodenal fistula,7 with colo-duodenal fistula,2 with sigmoido-duodenal fistula and 1 with duodeno-enteric fistula.All patients received duodenal fistula repair + resection of diseased intestine.Patients were followed up via out-patient examination,phone call and email till May 2014.The condition of patients before and after enteral nutrition support was compared using the t test.Non-normal data were analyzed using the Mann-Whitney u test.Results Two patients with abdominal infection and 1 with gastrointestinal bleeding received emergent operation,and the other 19 patients received enteral nutrition support prior to operation.Three patients received emergent colostomy.Two patients had fistula at the duodenal anastomosis,and 1 patient was cured by enteral nutrition support + drainage for 12 days and the other 1 received reoperation.The energies provided by enteral nutrition and enteral + parenteral nutrition were (25.3 ± 2.1) cal/g and (28.5 ± 3.2) cal/g,respectively,and the time for nutrition support was (31 ± 5)days.The level of C-reaction protein and Crohn's disease activity index were decreased from 25 mg/L and 207 ± 111 before treatment to 2 mg/L and 117 ± 71 after treatment,with significant difference (u =53.000,t =0.942,P ＜ 0.05).The levels of body mass index,albumin and blood sedimentation rate were (17.0 ± 2.1) kg/m2,(35 ± 5) g/L and 26 mm/h before treatment,and (17.9 ± 2.8) kg/m2,(38 ± 5) g/L and 23 mm/h after treatment,with no significant differences (t =0.482,1.170,u =67.500,P ＞ 0.05).One patient was cured by enternal nutrition.Five patients received intestinal stoma and the other 13 patients received intestinal anastomosis.Twenty-two patients were followed up with the median time of 13.4 months (range,4.0-37.0 months).One patient had recurrence of ileocolonic anastomosis-duodenal fistula and received reoperation,and complications were not observed in the other 21 patients.Conclusions Selective operation is recommended for patients with Crohn's disease complicated with duodenal fistula.Enteral nutrition support is the first choice during the interoperative management.Resection of diseased intestine combined with repair of duodenal fistula after alleviation of Crohn's disease and malnutrition could achieve satisfactorv effect.

OBJECTIVETo compare short-term outcomes of laparoscopic vs. open intestinal resection in patients with Crohn's disease (CD) under enhanced recovery after surgery(ERAS) program.

METHODSClinical data of 51 CD patients receiving laparoscopic surgery under ERAS program at our IBD center between January 2013 and March 2014 were retrospectively analyzed. Laparoscopic cases were matched to those undergoing open surgery from June 2011 to December 2012 with age, gender, location and behavior of disease. Intraoperative and postoperative data were collected.

RESULTSFifty-one laparoscopic cases were matched with 51 open cases. Laparoscopic group had a shorter median length of postoperative hospital stay (7 d vs. 9 d, P=0.034), shorter median time to first passage of gas(45 h vs. 59 h, P=0.024), shorter time to bowel movement(58 h vs. 76 h, P=0.018), less intraoperative estimated blood loss (35 ml vs. 75 ml, P=0.034) and longer median operative time (145 min vs. 105 min, P=0.003). Postoperative complications, reoperation and 30-day re-admission rates were similar and there was no mortality in the two groups.

CONCLUSIONLaparoscopic surgery is a safe and acceptable option for CD patients, and it promotes recovery of gastrointestinal movement and shortens postoperative hospital stay.

Background: Bovine papillomatosis is a type of proliferative tumor disease of skin and mucosae caused by bovine papillomavirus (BPV). As a transboundary and emerging disease in cattle, it poses a potential threat to the dairy industry. Objectives: The aim of this study is to detect and clarify the genetic diversity of BPV circulating in dairy cows in Xinjiang, China. Methods: 122 papilloma skin lesions from 8 intensive dairy farms located in different regions of Xinjiang, China were detected by polymerase chain reaction. The genetic evolution relationships of various types of BPVs were analyzed by examining this phylogenetic tree. Results: Ten genotypes of BPV (BPV1, BPV2, BPV3, BPV6, BPV7, BPV8, BPV10, BPV11, BPV13, and BPV14) were detected and identified in dairy cows. These were the first reported detections of BPV13 and BPV14 in Xinjiang, Mixed infections were detected, and there were geographical differences in the distribution of the BPV genotypes. Notably, the BPV infection rate among young cattle (< 1-year-old) developed from the same supply of frozen sperm was higher than that of the other young cows naturally raised under the same environmental conditions. Conclusions Genotyping based on the L1 gene of BPV showed that BPVs circulating in Xinjiang China displayed substantial genetic diversity. This study provided valuable data at the molecular epidemiology level, which is conducive to developing deep insights into the genetic diversity and pathogenic characteristics of BPVs in dairy cows.

The emergence and evolution of digital intelligent technology has profoundly influenced the development of minimally invasive research-oriented hepatobiliary and pancreatic surgery discipline. Over various periods, our team has always adhered to the principle of "being oriented by clinical issues and driven by clinical needs", continuously carried out innovative research across interdisciplinary boundaries, propelling the evolution of digital intelligent technology. Spanning over two decades, this journey includes the progression from digital virtual human, three-dimensional visualization, molecular fluorescence imaging, augmented reality and mixed reality, artificial intelligence, to the realm of human visualization meta-universe. This evolution facilitates the shift from two-dimensional empirical diagnoses of hepatobiliary and pancreatic surgical diseases to deep learning intelligent diagnostics, the transition from morphology-based tumor diagnoses to molecular imaging-based diagnostics, and from conventional empirical surgery to intelligent navigation surgery. The authors provide a comprehensive review of our developmental process and achievements within the realm of digital intelligent diagnostic and therapeutic technologies, with the aims to promote the development and application of digital intelligent medicine.

Cancer genomics has led to the discovery of numerous oncogenes and tumor suppressor genes that play critical roles in cancer development and progression.Oncogenes promote cell growth and proliferation,whereas tumor suppressor genes inhibit cell growth and division.The dysregulation of these genes can lead to the development of cancer.Recent studies have focused on non-coding RNAs(ncRNAs),including circular RNA(circRNA),long non-coding RNA(lncRNA),and microRNA(miRNA),as therapeutic targets for cancer.In this article,we discuss the oncogenes and tumor suppressor genes of ncRNAs associated with different types of cancer and their potential as therapeutic targets.Here,we highlight the mechanisms of action of these genes and their clinical applications in cancer treatment.Understanding the molecular mechanisms underlying cancer development and identifying specific therapeutic targets are essential steps towards the development of effective cancer treatments.

AIM:This study aimed to investigate the mechanism by which celoside I enhances mitophagy in a model of optic nerve injury through regulation of reactive oxygen species(ROS)-mediated c-Jun N-terminal kinase(JNK)/c-Jun signaling pathway.METHODS:Twenty-four New Zealand white rabbits were randomly divided into four groups:sham surgery,model,mecobalamin,and experimental group.Optic nerve injury was induced in the model,mecobala-min,and experimental groups,while the sham surgery group underwent a sham procedure.The mecobalamin group re-ceived mecobalamin,the experimental group received celoside I,and the sham surgery and model groups received saline.Interventions were administered daily for 28 d.Various techniques including endoscopy,hematoxylin-eosin(HE)stain-ing,TUNEL method,immunofluorescence staining and Western blot were used to assess fundus condition,retinal mor-phology,apoptosis,ROS expression,and protein levels in the retina.RESULTS:Fundus examination revealed im-proved blood flow in the mecobalamin and experimental groups compared to the model group.Retinal morphology showed enhanced retinal ganglion cells(RGCs)in the mecobalamin and experimental groups.Apoptosis index was lower in the mecobalamin group compared to the experimental group.Immunofluorescence staining indicated reduced ROS and P62 ex-pression and increased parkin and microtubule-associated protein light chain 3(LC3)expression in the experimental group compared to the mecobalamin group.Protein analysis showed decreased JNK,c-Jun,and P62 levels,and increased parkin and LC3 levels in the mecobalamin and experimental groups compared to the model group.CONCLUSION:Celo-side I reduces ROS expression,inhibits the JNK/c-Jun pathway,enhances mitophagy,reduces apoptosis,and protects RGCs in optic nerve injury models.
