ObjectiveTo detect the expressions of Nuclear factor-erythroid 2 p45-related factor 2 (NRF2) and multidrug resistance-associated protein 2 (MRP2), and investigate their significance in primary gallbladder carcinoma. MethodsImmunohistochemistry SP assay and image analysis were used to detect the expressions of NRF2 and MRP2 protein in 59 patients with primary gallbladder carcinoma. ResultsA highly positive expression rates of NRF2 and MRP2 were found (76.3% and 74. 6%, respectively) in primary gallbladder carcinoma. The expressions of NRF2 and MRP2 had a significantly correlation with metastases, Nevin staging, and differentiation (P＜0.05), but there was no statistical association with sex and age. The expression of NRF2 had a positive correlation with MRP2 (r=0. 589,P＜0.05). Conclusion Both NRF2 and MRP2 were overexpressed in primary gallbladder carcinoma and they may play a role in the development of primary gallbladder carcinoma.

Objective To compare the efficacy between bronchial artery infusion (BAI) chemotherapy plus radiation therapy and systemic chemotherapy plus radiation for locally advanced non-small cell lung cancer (NSCLC). Methods One hundred and twenty-one patients with stage III NSCLC were randomized into treatment group(58 cases) and control group (63 cases). In the treatment group, all patients were administered with BAI for 2-3 sessions, followed by irradiation 4-7 days after BAI. In the control group, altogether 4-6 cycles of standard systemic chemotherapy were given. Radiation was delivered alternately between the cycles of chemotherapy. Results The short-term, long-term survival, median response duration and median survival time were similar between the two groups, except patients with stage Ⅲb who had a higher distant metastasis rate in the treatment group. The major side effects of chemotherapy and radiotherapy were hematological, gastrointestinal toxicities, pneumonitis, mediastinitis, and esophagitis, respectively. The side effects were milder, better tolerated and did not influence the regimen schedule in the treatment group, as compared with the control group. Seven patients withdrew from the control group, and in 28 patients, the scheduled chemotherapy and radiation was delayed or canceled. Conclusions Bronchial artery infusion plus radiation is more advantageous over systemic chemotherapy plus radiation in less toxicities, better compliance, shorter treatment courses and more cost-effectiveness.

Liver transplantation is a vital treatment for end-stage liver disease. However, the shortage of donor livers has limited the development of liver transplantation. How to expand the source of donor livers has become a challenge in the academic community. In recent years, the proportion of donors with non-alcoholic fatty liver disease (NAFLD) has been increased. Rational use of steatotic donor livers is a feasible approach to expand the donor pool. Cold ischemia injury during donor liver preservation before liver transplantation increases the risk of postoperative organ dysfunction. Therefore, it is of significance to unravel the mechanism and intervention measures of cold ischemia injury of steatotic donor livers. Cold ischemia injury of steatotic donor livers is characterized as the damage of mitochondria, lysosomes and endoplasmic reticulum at the organelle level, and up-regulated expression of adenosine monphosphate activated protein kinase (AMPK), aldehyde dehydrogenase 2 (ALDH2) and heme oxygenase (HO)-1 at the protein level. In this article, the research progresses on cold ischemia injury of steatotic donor livers and relevant intervention measures were reviewed.

Fibromyalgia syndrome (FMS), also known as fibromyalgia, is clinically characterized by diffuse chronic muscle and bone pain, accompanied by fatigue, sleep disturbances, depressive episodes, and cognitive and intestinal dysfunction. Due to lack of clear specific laboratory indicators and appropriate imaging examinations, FMS diagnosis is mostly based on clinical symptoms, but FMS clinical symptoms of lack specificity, and current clinical diagnostic criteria are mostly exclusive criteria, which is prone to missed diagnosis and misdiagnosis. In order to further promote the standardized diagnosis and treatment of FMS, this paper makes extensive references to laboratory-related diagnostic indexes of FMS (Tau, adiponectin, serum cathepsin S, cystatin C, serum ferritin, nitric oxide, neutrophil/lymphocyte ratio, platelet distribution width and mean platelet volume) at home and abroad, aiming to provide new ideas for early diagnosis and intervention of FMS.

Objective To analyze the effects of rapid rehabilitation surgical procedures on recovery and stress response in patients undergoing hepatectomy.Methods Retrospective analysis of 60 patients with liver resection in Zhujiang Hospital of Southern Medical University from January 2012 to December 2015,40 males and 20 females.According to the rehabilitation method,it was divided into intervention group (n=30) and control group (n=30).The operation time,intraoperative blood loss,postoperative complications,and interleukin-6 (IL-6),C-reactive protein (CRP),and white blood cell count (WBC) on days 1st,3rd,and 5 th before and after surgery were compared between the two groups.Results Both groups completed the operation successfully.There was no significant difference in intraoperative blood loss and operation time between the two groups (P＞0.05).The duration of postoperative ventilation and postoperative hospitalization in the intervention group was less than that in the control group,and the incidence of postoperative complications (23.3％ vs.50.0％) and the first and second day after surgery were lower than those in the control group,with statistically significant differences (P＜0.05).On the first,third and fifth days after surgery,IL-6 and CRP in the intervention group were lower than those in the control group,respectively (64.96± 24.10) μg/L vs.(286.74±67.98) μg/L,(60.52±18.31)μg/L vs.(162.33±52.62) μg/L,(31.61± 9.42) μg/L vs.(77.44±24.54)μg/L and (24.64±17.45) mg/L vs.(41.46±20.79) mg/L,(81.11± 36.58) mg/L vs.(117.23±44.80) mg/L,(44.90±22.31) mg/L vs.(65.27±38.05) mg/L,the differences were statistically significant (P＜0.05).Conclusion The concept of rapid rehabilitation surgery applied to patients with hepatectomy can reduce postoperative stress response,reduce postoperative complications,and accelerate the recovery process.

Objective    To systematically evaluate the risk factors for postoperative pulmonary infection in patients with esophageal cancer. Methods    CNKI, Wangfang Data, VIP, CBM, PubMed, EMbase, The Cochrane Library were searched from inception to January 2021 to collect case-control studies, cohort studies and cross-sectional studies about risk factors for postoperative pulmonary infection in patients with esophageal cancer. Two researchers independently conducted literature screening, data extraction and quality assessment. RevMan 5.3 software and Stata 15.0 software were used for meta-analysis. Results    A total of 20 articles were included, covering 5 409 patients of esophageal cancer. The quality score of included studies was 6-8 points. Meta-analysis results showed that age (MD=1.99, 95%CI 0.10 to 3.88, P=0.04), age≥60 years (OR=2.68, 95%CI 1.46 to 4.91, P=0.001), smoking history (OR=2.41, 95%CI 1.77 to 3.28, P<0.001), diabetes (OR=2.30, 95%CI 1.90 to 2.77, P<0.001), chronic obstructive pulmonary disease (OR=3.69, 95%CI 2.09 to 6.52, P<0.001), pulmonary disease (OR=2.22, 95%CI 1.16 to 4.26, P=0.02), thoracotomy (OR=1.77, 95%CI 1.32 to 2.37, P<0.001), operation time (MD=14.08, 95%CI 9.64 to 18.52, P<0.001), operation time>4 h (OR=3.09, 95%CI 1.46 to 6.55, P=0.003), single lung ventilation (OR=3.46, 95%CI 1.61 to 7.44, P=0.001), recurrent laryngeal nerve injury (OR=5.66, 95%CI 1.63 to 19.71, P=0.006), and no use of patient-controlled epidural analgesia (PCEA) (OR=2.81, 95%CI 1.71 to 4.61, P<0.001) were risk factors for postoperative pulmonary infection in patients with esophageal cancer. Conclusion    The existing evidence shows that age, age≥60 years, smoking history, diabetes, chronic obstructive pulmonary disease, pulmonary disease, thoracotomy, operation time, operation time>4 h, single lung ventilation, recurrent laryngeal nerve injury, and no use of PCEA are risk factors for postoperative pulmonary infection in patients with esophageal cancer. Due to the limitation of the quantity and quality of included literature, the conclusion of this study still needs to be confirmed by more high-quality studies.
