ObjectiveTo review the advances of lymphocinesia in the abdominal cavity infection. MethodsDomestic and foreign literatures about the research of lymphocinesia in the abdominal cavity infection were collected and reviewed. ResultsBacterial translocation occurred when abdominal infection happened. At early phase, bacteria and endotoxin translocation could return and arrive the other tissues or organs through the lymphatic system. The peritoneal lymphatic stomata played an important role in lymphatic circulation, with strong absorption function and immune function. ConclusionsThe theory of lymphatic channels and lymphatic stomata immune pathway is a beneficial supplement to the theory that bacterial and endotoxin can spread to whole body through portal vein pathway, and combination of the 2 kinds of theories can explain the abdominal infection-related systematic infection better. Research of abdominal infection intervention which embarked on the lymphatic pathways would be a promising field.
Objective To summarize the experience of the surgical treatment of complex congenital heart diseases in 29 newborns. Methods Twenty-nine newborns were operated on for various congenital heart diseases, ages were from 3 to 28 d. There were ventricular septal defect 3 cases, D-transposition of the great arteries (D-TGA) 10 cases, pulmonary atresia (PA) 1 case,tricuspid atresia 3 cases, single ventricle 1 case, tetralogy of Fallot 6 cases, endocardial cushion defect 4 cases and truncus arteriosus 1 case. All patients were combined with atrial septal defect and patent ductus arteriosus. All operations were performed under hypothermic cardiopulmonary bypass. Results The operative mortality was 13.8%(4/29). One case with D-TGA and 1 case with PA succumbed due to low cardiac output syndrome, and 2 cases due to acute respiratory distress syndrome and low blood oxygen saturation. Twenty-five cases were discharged. Follow-up was completed in 19 patients,with a duration of 1-31 months, all patients have been normal. Conclusion Anesthesia and cardiopulmonary bypass should be performed smoothly and satisfactorily in newborn babies for cardiac surgery. Surgical manipulation should be accurate with less trauma and well protection of myocardium and lung is important.
Objective To investigate the characteristic of the expression of facilitative glucose transporter 1 （Glut1） in bronchial aveolar carcinoma （BAC） and the relationship between expression of Glutl and fluorine-18 fluorodeoxyglucose （18F-FDG） uptake. Methods Twenty patients with BAC were imaged with 18F-FDG positron emission tomography （PET） before surgery. Maximum standard uptake value （SUVmax） and mean standard uptake value （SUVmean ） of tumor and standard uptake value of normal lung （SUVIung） were measured. The expression of Glutl was studied in paraffin sections by streptavidin peroxidase （SP） immunohistochemistry. Results All tumors of the patients could be detected by ^18F-FDG-PET. 18F-FDG uptake of tumor was higher than that of normal lung （SUV SUV and SUVlong were 3.09± 1.35, 2.37±1.03 and 0.39±0.09 respectively）. The expression of Glutl were positive in all tumors （73. 8%± 14. 8% of positive cell rate, 2. 8 ± 0. 9 grade of staining intensity）. Predominantly cytoplasm positive with weak staining intensity were observed in many tumors. Glutl negtive were observed in normal bronchial and lung parenchyma. Positive correlations were found among 18F-FDG uptake, Glut1 expression and tumor size （P〈0. 01）. Conclusion Glutl expression with peculiarity in BAC is correlate with 18F-FDG uptake.

ObjectiveTo analyze the cause of complications for patients with advanced malignant biliary obstruc-tion treated with percutaneous transhepatic implantation of biliary stent (PTBS) and summarize the experiences of comp-lications of the treatment. MethodThe complications of 59 patients firstly treated with percutaneous transhepatic cholangial drainage (PTCD) then with PTBS in 156 cases of advanced malignant biliary obstruction from January 2010 to January 2013 in this hospital were analyzed retrospectively. ResultsFifty-nine cases of complications were occurred in 156 cases of advanced malignant biliary obstruction, the incidence was 37.8%, including biliary infection in 26 cases, bile duct bleeding in 17 cases, liver failure in 5 cases, renal failure in 4 cases, acute pancreatitis in 4 cases, stent displa-cement in 2 cases, bile duct perforation in 1 case.Three cases died in 59 patients with complications, 56 cases were improved after symptomatic treatment. ConclusionPTCD combined with PTBS is a safe and effective treatment of advanced malignant biliary obstruction, the reasonable perioperative management is very important to reduce the occurrence of complications.
ObjectiveTo summarize the mechanism of neutrophil extracellular traps (NETs) in hepatic ischemia-reperfusion injury (HIRI) and the research progress in targeting NETs to reduce HIRI, providing valuable reference for reducing HIRI. MethodThe related literatures at home and abroad about the role of NETs in the pathogenesis of HIRI and target NETs to alleviate HIRI were retrieved and reviewed. ResultsHIRI usually appeared in the process of liver surgery and was a common clinical problem, which occured in situations such as liver surgery, organ transplantation, liver ischemia and so on. This kind of injury would lead to tissue necrosis, inflammatory response and oxidative stress, which was a major cause of hepatic dysfunction and multiple organ failure after hepatic surgery, greatly increases the complications and mortality after hepatic surgery. NETs played a crucial role in the aseptic inflammatory response induced by hepatic ischemia/reperfusion. During hepatic ischemia-reperfusion, neutrophils promoted inflammatory cascade reactions and cytokine storms by forming NETs, exacerbating damage caused by hepatic ischemia-reperfusion. At present, some experimental and clinical studies had shown that inhibiting the formation of NETs or eliminating the formed NETs could alleviate the hepatic ischemia-reperfusion injury and improve the prognosis. ConclusionsTargeting NETs may become a new method for treating hepatic ischemia-reperfusion injury. In the future, it is foreseeable that more experiments and clinical trials will be conducted on targeted NETs for the treatment of hepatic ischemia-reperfusion injury. And gradually establish more comprehensive and effective treatment strategies, thereby providing new ways to improve the prognosis of hepatic surgery patients in clinical practice.
Objective To study the protective effects of pre-storing glycogen on warm ischemia reperfusion injury during partial hepatectomy. Methods Thirty-eight patients were randomly divided into a trial group (n=19) and a control group (n=19). In the trial group, patients were given high concentration glucose intravenously during the 24 hours before the operation. The hepatic lesion was resected after portal triad clamping in the two groups. Liver function of all patients was measured before the operation and the first and fifth days after the operation. Normal hepatic tissue was biopsied to measured hepatic tissue glycogen contents before the operation and the change of superoxide dismutase (SOD) at the point of pre-ischemia, post-ischemia, and reperfusion 2 hour. Bcl-2 mRNA, a well known anti-apoptotic factor, was also detected using quantitative polymerase chain reaction. Results The hepatic tissue glycogen content of the trial group was significantly higher than that of the control group before the operation (Plt;0.01). Liver function of the trial group was significantly better than that of the control group on the first and fifth day after operation (Plt;0.05). There was significant difference in SOD activity between the two groups at the end of hepatic vascular occlusion and at the point of 2-hour reperfusion (Plt;0.05). Furthermore Bcl-2 mRNA expression of the trial group was notably up-regulated at the point of 2-hour reperfusion compared to the control group. Conclusion Pre-store storing glycogen might protect liver ischemia reperfusion injury caused by hepatic vascular occlusion during partial hepatectomy. The potential mechanism might be that pre-storing glycogen enhances Bcl-2 expression.
