ABSTRACT
Objective To predict the target of Atractylodes-Panxia-Poria in the treatment of pancreatic cancer, and to explore its potential molecular mechanism by using network pharmacology and molecular docking. Methods Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP), PharmMapper, OMIM, GeneCards, STRING, DAVID and Cytoscape software were used to construct a series of network diagrams. The core targets and conduct GO analysis and KEGG pathway enrichment analyses of the target genes were selected. Finally, molecular docking verification of key active ingredients and potential targets were conducted by AutoDock software. Results A total of 35 active ingredients, 190 related targets, 1566 targets of pancreatic cancer and 76 intersection targets were screened for the treatment of pancreatic cancer with Atractylodes-Panxia-Poria. These intersection targets were mainly involved in several biological processes, including positive regulation of gene expression, cytokine-mediated signaling pathway and regulation of apoptotic process, etc, which were also related to pathways in cancer, hepatitis B, colorectal cancer, chemical carcinogenesis-receptor activation, pancreatic cancer, and MAPK signaling pathway, etc. Molecular docking results showed that the main active components of Atractylodes-Panxia-Poria had certain affinity with the potential targets of pancreatic cancer. Conclusion Atractylodes-Panxia-Poria mainly exerts a therapeutic effect on pancreatic cancer through multi-component, multi-target and multi-pathway, which provides a certain theoretical basis for the clinical application of Atractylodes -Panxia-Poria in the treatment of pancreatic cancer.

ABSTRACT
Objective To study the effects of three ferroptosis inducers Erastin (Era), sulfasalazine (SASP) and artesunate (Art) alone or combined with gemcitabine hydrochloride (hcGEM) on the proliferation inhibition of Human pancreatic cell line PANC -1. Methods The CCK-8 method was used to detect the inhibitory effects of different concentrations of Era, SASP and Art alone or combined with hcGEM on the proliferation of PANC-1, and the combination index (CI) was used to judge whether three ferroptosis inducers combined with hcGEM had synergistic inhibitory effect on PANC-1. Results The three ferroptosis inducers and hcGEM alone or in combination could significantly inhibit the activity of PANC-1. The inhibitory effects were enhanced with the concentration increasing. The CI values of hcGEM-Era 4∶1 or 1∶4 combination group and hcGEM-SASP 1∶400 combination group were less than 1.The CI values of hcGEM-Art 1∶4 or 1∶16 combination group were less than 1 only within a certain concentration range. Conclusion The inhibitory effects of the three ferroptosis inducers and hcGEM alone or in combination were dose-dependent. The combination of hcGEM and three ferroptosis inducers could synergistically inhibit the proliferation of PANC-1.

ABSTRACT
Objective To investigate the value of choledochoscopy in the treatment of intrahepatic bile duct stones complicated by biliary stricture,treatment methods,and related complications.Methods A retrospective analysis was performed for the clinical data of 230 patients with intrahepatic bile duct stones complicated by biliary stricture who underwent choledochoscopy in Jiangning Hospital Affiliated to Nanjing Medical University from June 2015 to May 2017.The treatment timing and duration of choledochoscopy,number of times of stone removal,and intraoperative complications were observed,and the patients were followed up for 1-3 months to observe residual stones,T tube detachment,and postoperative gastrointestinal reactions.Results Of all patients,229 had benign biliary stricture and 1 had malignant biliary stricture found by choledochoscopy.A total of 692 person-times of choledochoscopy were performed,and the patients underwent 2-7 times of choledochoscopy (mean 3.9 ± 1.1).Each time of choledochoscopy lasted for 25-60 minutes (mean 40.9 ± 11.5 minutes).Choledochoscopy was performed during 90-120 days after surgery (mean 105.0-± 9.5 days).Eight patients experienced T tube detachment,and six of them underwent successful T tube replacement.Of all patients,4 had residual stones after choledochoscopy,resulting in a residual stone rate of 1.73％.There were 83 person-times of postoperative complications including pyrexia,nausea,and diarrhea,which were relieved after symptomatic treatment.Conclusion Choledochoscopy is an important supplemental therapy for the surgical treatment of intrahepatic bile duct stones complicated by biliary stricture and has the features of high efficiency,small trauma,and rapid recovery.Therefore,it holds promise for clinical application.
ABSTRACT
BACKGROUND:In recent years, vacuum sealing drainage technology has been widely used in the treatment of orthopedic wounds or to facilitate skin graft survival, both of which have achieved good results. OBJECTIVE:To observe the curative effects of vacuum sealing drainage technology in the wound healing after limb open fractures, soft tissue defects, pressure sores, and chronic osteomyelitis. METHODS:Fifty-four patients of fractures combined with soft tissue defects, postoperative exposed bone, osteomyelitis, a large area of pressure ulcers or severe infections, selected from the 273rd Hospital of PLA, were randomly divided into test and control groups according to the wishes of patients. The test group included 36 patients who were treated with vacuum sealing drainage using polyethylene ethanol hydration seaweed salt after debridement, and the control group included 18 patients who were treated with conventional dressing. Wound cleaning time, number of dressings, and wound healing time were detected and compared in the two groups. RESULTS AND CONCLUSION:Compared with the control group, the wound cleaning time and wound healing time were shorter in the test group, and the number of dressings was also decreased in the test group (P<0.05). After removal of sponge dressings, in the test group, wound granulation was fresh and grew obviously with no exudates after the necrotic residue was removed and vacuum sealing drainage was changed. For the bone exposure patients, the wound area was reduced, or even there was no exposed bone any more. After skin grafting, vacuum suction and pressure due to vacuum sealing drainage technology made al skin grafts survive. In the patients with chronic osteomyelitis, the exudates were gradual y reduced until disappeared after vacuum sealing drainage was exchanged three or four times, and pathogens were not found in bacterial culture. After combined treatment of debridement and vacuum sealing drainage, there were many fresh granulations in the patients with large areas of pressure sores;after replacement of vacuum sealing drainage several times, the granulation grew to the same height with the surrounding skin.
