Intra-abdominal infections(IAIs) are common surgical emergencies and complications, which usually need multidisciplinary management including surgeons, intensivists, infectious disease experts, microbiologists, and clinical pharmacists. Based on international and domestic guidelines and recent advances, a number of experts' statements of consensus, with a problem-oriented approach, were made on the cornerstones of effective treatment of IAIs such as early recognition, etiology identification, adequate source control, and appropriate antimicrobial therapy. Main recommendations include concepts of intra-abdominal infection, pathoqen diagnosis precautions; surgical intervention principles and strategies of specific causes including acute appendicitis, upper gastrointestinal perforation, lower gastrointestinal perforation, acute biliary infection, liver abscess, severe acute pancreatitis, pancreatic fistula, biliary fistula, anastomotic leakage, gastrointestinal perforation, as well as perforation due to endoscopic procedure etc.; principles of antimicrobial therapy, dosage of antibiotics in specific population and pathophysiological state; and systematic support of severe infection such as early resuscitation and nutrition support.Apparent diffusion coefficient(ADC) of magnetic resonance imaging≤0.90×10-3 mm2/s and T2-hypointensity, intratuminal septa, and peritumoral infiltration could achieve best diagnostic efficiency. ADC values and cyst or necrosis were independent predictors for the differential diagnosis of nonseminomatous germ cell tumor versus seminoma and nonseminomatous germ cell tumor versus lymphoma. ADC value and intratuminal septa were independent predictors for the differential of seminoma versus lymphoma.Objective To investigate the molecular mechanism of nest metastasis in blood vessels encapsulated by tumor clusters (VETC) positive hepatocellular carcinoma (HCC). Methods A total of 72 paraffin embedded HCC tissue samples were collected. Immunohistochemistry staining with CD34 (vascular endothelial cell marker protein) was used to observe the morphological manifestations of VETC cancer nests in primary tumors, bile duct cancerous thrombi and portal vein cancerous thrombi, and to study the characteristics of hematogenous metastasis of VETC cancer nests. Bioinformatics was used to predict the key proteins closely related to VETC cancer nest formation. Immunohistochemistry was used to detect the expression of angiogenin-2 (Ang-2), integrin α5, Integrin β1, and cyclooxygenase-2 (COX-2) proteins in HCC. Transwell cell migration assay was used to detect the effect of Ang-2/integrin α5β1 protein on the migration ability of endothelial cells and HCC cells. Western blotting was used to detect the effect of Ang-2/inte, P less then 0.05]. ATN-161 could significantly block the phosphorylation of FAK in HCC and endothelial cells induced by Ang-2. Conclusions VETC (+) HCC could metastasize as a whole in a nested form, and possesses a specific regulatory protein. Go6983 Ang-2/α5β1/FAK might be potential protein targets in the treatment of VETC (+) HCC nest-type metastasis.Objective To compare the effectiveness and safety of different methods to construct animal models of aortic arch dissection (AAD), and explore safe and effective methods for constructing AAD animal models. Methods Twenty-four healthy mongrel dogs were divided into 4 groups by random number table (n=6). Group A Venous incision needle high pressure water flow impact method; Group B Venous incision needle non-high pressure water flow impact method; Group C Transarterial sheath non-high pressure water flow impact method; Group D Two-way balloon expansion combined with elastase perfusion method. Imaging examinations were performed immediately and 7 days after operation, aortic tissue biopsy and pathological staining were performed 15 days after operation to observe the formation of AAD. The operation time, aortic blood flow block time, model construction success rate, dissection tear length, postoperative survival rate and survival time of four groups of experimental dogs were collected to compare the effectivenesmodeling method is easy to operate. The aortic blood flow block time is short, the dissection tear length is wide, and the postoperative survival time is long, can be used as the preferred method of animal AAD model construction.Objective To explore the clinical effect of lumbar discectomy and nerve root canal's enlargement preserving the continuity of supraspinous ligament in the treatment of lumbar degenerative disease. Methods The data of patients with lumbar degenerative disease who underwent operation from 2016 to 2018 were analyzed retrospectively, and the patients were divided into two groups according to the different operation. The treatment group (17 cases) was treated with recapping laminoplasty, lumbar discectomy and nerve root canal's enlargement, and the control group (28 cases) was treated with total laminectomy, nerve root canal's enlargement, lumbar discectomy, interbody fusion and internal fixation (PLIF). All patients were followed up for 12 to 27 months (mean 17.8 months). Japanese Orthopaedic Association Scores(JOA) and visual analogue scale(VAS) of pain were used to evaluate the clinical effect before and after the operation, lumbar dynamical X-ray and Cobb angle were collecting for imaging evaluation, and the as found in all patients. Conclusion Treatment of lumbar degenerative diseases with recapping laminoplasty and nerve root canal's decompression preserving the continuity of supraspinous ligament by ultrasound osteotome has the same clinical effect as PLIF. It has the advantages of shortening operation time, less bleeding, better maintenance of lumbar lordosis after operation and reduction of adjacent segment degeneration.Objective To explore The feasibility of digital guidance drill templates assisted expansive open-door laminoplasty. Methods Ten specimens of normal adult cervical spine (C3-7) were selected, including six males and four females. The specimens aged 42-67 years, with an average age of (43.6±4.2) years. After CT scanning, the date was imported into Mimics software in DICOM format. 3D models were reconstructed and the position and depth of troughs on the open side and hinge side were selected for expansive open-door laminoplasty. Drill templates were designed and exported in STL, manufactured by 3D printing finally. Then drill templates were attached to the posterior part of cervical lamina and spinous process. Under guidance of templates, troughs of both sides were conducted by using a high-speed drill. Then the lamina is elevated and instrumentations were implanted. Postoperative CT scanning was conducted to record the fracture of trough on the hinge side. 3D reconstruction was performed again to compare the position and depth between theory and actual trough on both sides by paired t test.
