Background:The prevalence rate of diabetes mellitus ( DM ) associated with gastroesophageal reflux disease ( GERD)is increasing recently,and the relationship between DM and GERD has become a research hotspot. Aims:To study clinical features and influential factors of therapeutic efficacy of reflux esophagitis( RE)in elderly patients with type 2 DM(T2DM). Methods:Two hundred elderly patients with RE diagnosed by gastroscopy from March 2011 to October 2013 were enrolled,and divided into T2DM associated with RE( T2DM)group and RE group. The clinical features, endoscopic findings and therapeutic efficacy of the two groups were analyzed,and the influences of DM course and control of blood glucose on efficacy of RE were also analyzed. Results:The main manifestations of RE were extraesophageal symptoms,typical esophageal symptoms were less common. The overall efficacy rate decreased with the increase of endoscopic grade of RE,however,extraesophageal symptoms improved significantly. With the prolonging of DM course,the endoscopic grade of RE was increased,and the control of blood glucose was worse. The overall therapeutic efficacy was significantly reduced with the prolonging of DM course in patients with well controlled blood glucose. Conclusions:Extraesophageal symptoms are common,endoscopic grade of RE is worse and blood glucose is difficult to control in elderly T2DM patients associated with RE. DM course and status of blood glucose control have influences on the therapeutic efficacy of RE.

Objective:To study the efficacy and safety of Hassab operation combined with either radiofrequency ablation(RFA) or liver resection in treatment of liver cancer associated with portal hypertension.Methods:A retrospective analysis was conducted on the clinical data of patients with primary liver cancer associated with portal hypertension operated at the Department of General Surgery of Beijing Ditan Hospital from June 2013 to June 2015. These patients were divided into the RFA combined with Hassab operation group and the liver resection combined with Hassab operation group according to the surgical procedures. The general patient information, operation time, intraoperative blood loss, intraoperative blood transfusion, postoperative hospital stay, postoperative complications and the 1-, 3-, and 5-years cumulative survival rates and recurrence-free survival rates were compared.Results:Of 53 patients who were included in the study, 30 patients were in the RFA combined with Hassab operation group (including 28 males and 2 females, average age 46.3 (27.0~64.0) years, and 23 patients in the liver resection combined with Hassab operation group (including 20 males and 3 females), average age 44.7(33.0~59.0) years. There were no significant differences in the general patient information including age, gender, maximum tumor diameter, preoperative laboratory tests (including blood routine, liver function, tumor markers), and Child-Pugh classification between the two groups (all P>0.05). Intraoperative blood loss in the RFA combined with Hassab operation group was significantly less than those in the liver resection combined with Hassab operation group [(401.67±183.12) ml vs (552.17±333.88) ml, P<0.05]. There were also no significant differences between the two groups in operation time, blood transfusion during operation, postoperative hospital stay, and postoperative complications ( P>0.05). The incidence of severe postoperative complications (Clavein-Dindo grade ≥ IIIb) in the liver resection combined with Hassab operation group was 47.8% (11/23), which was significantly higher than the 20.0% (6/30) in the RFA combined with Hassab operation group ( P<0.05). The 1-, 3-, and 5-year cumulative survival rates of patients in the RFA combined with Hassab operation group were 82.8%, 49.9%, and 33.2%, respectively, while the corresponding survival rates of patients in the liver resection combined with Hassab operation group were 81.0%, 58.2%, 43.7%, respectively. There was no significant difference between the two groups ( P>0.05). The recurrence-free survival rates of patients in the RFA combined with Hassab operation group at 1-, 3-, and 5-years after surgery were 79.2%, 38.8%, and 21.6%, respectively. The corresponding recurrence-free survival rates of patients in the liver resection combined with Hassab operation group were 76.4%, 41.7%, and 27.8%, respectively, and there was no significant difference between the two groups ( P>0.05). Conclusion:RFA combined with Hassab operation was safe and efficacious to treat primary liver cancer associated with portal hypertension.

In recent years, immunotherapy for hepatocellular carcinoma has gradually become a hot spot in clinical research. The characteristic of its immunotherapy is to stimulate specific immune response, enhance the immune rejection of tumors, inhibit and kill tumor cells, thereby reducing the possibility of tumor recurrence and metastasis. A large number of previous experimental studies have shown that immunotherapy has the potential advantages of monotherapy or combination therapy in the treatment of primary liver cancer. As we all know, whether it is to kill tumor cells in the short term or to control tumor recurrence in the long term, the necessary condition for immune drugs to work is a healthy immune environment. This article reviews the immune microenvironment in patients with liver cancer and the changes in the tumor immune microenvironment after various operations or treatments. It provides references for exploring mutually synergistic treatment plans for liver cancer, and hopes to help improve the prognosis of these patients.

OBJECTIVETo analyze the non-invasive indexes for predicting esophageal varices (EV) in liver cirrhosis, and to establish a model for predicting the degree of EV.

METHODSA total of 294 patients with liver cirrhosis and portal hypertension were divided into the following groups according to EV grade as assessed by endoscopy: non-EV and grade I EV, grade II EV and grade III EV. The non-invasive EV predictive measures of liver stiffness (LS), platelet (PLT) count, spleen thickness (ST), PLT/ST ratio, portal vein diameter, portal vein flow velocity and Child-Pugh score (CPS) were assessed by univariate analysis and multivariate logistic regression analysis, and used to generate a predictive model. The t-test, chi-square test, logistic analysis and receiver operating characteristic (ROC) curve were used in statistical analyses.

RESULTSThe area under the ROC for the new model was 0.990. The best cutoff value for the score was 0.898, as defined from the ROC. The sensitivity of the model was 96.5%, and the specificity was 99.2%.

CONCLUSIONSThe model for predicting EV was composed of LS, PLT count, ST, PLT/ST and CPS, which was accurate and sensitive, and could be used to predict EV in clinic.
