High mobility group box 1 protein (HMGB1), a damage-associated molecular pattern, exists ubiquitously in the cells of mammals. It contributes to maintaining the structure of nucleosome and modulating transcription of gene in nuclei. Extracellular HMGB1 plays two-way roles in promoting inflammatory and tissue repair. Released actively as well as passively following cytokine stimulation during cell death, HMGB1 may act as a late inflammatory factor and an endogenous damage-associated molecular pattern recognized by its receptors. And it may mediate the occurrence, development and outcome of the inflammatory injury of digestive system diseases, such as gastric mucosal injury, inflammatory bowel-disease, liver injury, pancreatitis, and so on. This review mainly concerns the research progresses of HMGB1 in the inflammatory injury of digestive system diseases. At the same time, HMGB1 itself, or as a therapeutic target, can promote tissue repair.

Objective Through the English newspaper reading activities to create the information transmission platform based on the medium of English,so as to improve the students' ability of receiving,understanding,conversion,processing,and output information.Methods Two natural classes of seven-year program students of Grade 2011 with no difference in Englishproficiencywere selected at randomas control group(30) and the experimental group(30).And reform on reading course has been performed in the experimental class by incorporating English newspaper reading into traditional teaching routine,while the control class maintain the traditional teaching routine.After the teaching,through CET 4 test scores to evaluate the teaching effect.Independent t-test was conducted on the performances of CET 4 between the experimental class and controlled class with the level of test α=0.05.Results The control group was higher than the experimental group inthe total scoreof CET 4 and the performance oflistening and reading,and there was significant difference between the two groups(P of totalscore=0.000,P of listening score=0.002,P of reading score=0.001).But there was no statistically significant difference in writing subtests between the two groups(P=0.072).Conclusion By adopting English newspaper reading and broadcasting in class,students' overall ability of using English has been greatly enhanced,especially the listening comprehension and reading comprehension; however,there is no significant change in the development of students' writing ability due to the tasks designed.

Objective To assess the effectiveness of Exenatide on non‐alcoholic fatty liver disease(NAFLD) with diabetes mellitus by evaluating fatty liver index(FLI) variation .Methods One hundred and two NAFLD patients with type 2 diabetes melli‐tus were enrolled and divided into two groups .One group were treated with Exenatide and another with Oral antidiabetic agents . The data of BMI ,blood fat ,HbA1c ,ALT ,AST ,GGT ,FLI and so on were collected at enrollment and the end point of 24 weeks treatment .The effectiveness of Exenatide were analysed by Kolmogorov‐Smirnov and Pearson correlation coefficient (r) analysis . Results The indicators of metabolic disorder ,the parameters of liver biochemistry and fatty liver disease (FLI) were significantly improved (P<0 .05) after 24 weeks treatment by Exenatide .While only BMI showed significant decrease after 24 weeks treatment with Oral antidiabetic agents(P<0 .05) .The rest of the parameters in oral antidiabetic agants group showed no significant differ‐ence (P>0 .05) .Conclusion Exenatide has a positive effect on non‐alcoholic fatty liver disease treatment who with type 2 diabetes mellitus ,especially for liver fat accumulation .

Clinical practice guidelines play an important role in practitioner and patient decisions regarding appropriate clinical health care and in health policy formation. In the guideline development process, inappropriate methodologies and development strategies significantly influence the quality of guidelines; therefore, research and evaluation of guidelines have great significance. The original Appraisal of Guidelines for Research and Evaluation (AGREE) instrument was published in 2003 by a group of international guideline developers and researchers. AGREE has important significance for the quality guarantee and successful implementation of guidelines, and has extensively achieved endorsement since 2003. In 2009, The AGREE Collaboration has developed the AGREE II by refining the original AGREE instrument. At present, the AGREE II has already replaced the original AGREE instrument; however, related introduction regarding AGREE II has not been found in China. The authors of this article briefly introduce the AGREE II, and believe that it will add value to research and evaluation of the guidelines as a whole.

Cognitive function has become a hot spot in the field of epilepsy. However,the relationship between cognitive function and epilepsy has not been clearly demonstrated. Clinical trials have showed that epi-lepsy and epileptic relevant factors are both associated with cognitive function in children. Children with cogni-tive impairment are often caused by those two factors. This article focuses on cognitive function in children with epilepsy age below 6 years,and mainly reviews the characteristics of cognitive function in these children with epilepsy.

Ceramide (Cer),as the center molecular of sphingolipids metabolism,functions as a bioactive mediator of different cellular processes,such as cell growth,differentiation,senescence and apoptosis,besides being structural component of cellular membrane.It can inhibit cell proliferation and promote cell apoptosis via multiple signal pathawys.Chemicals anti-cancer properties based on Cer metabolism that upregulate its level are confirmed in plenty of experimental researches,and parts of research productions are applied in anticancer clinic experiments.

The check methods of thyroid nodules include palpation,serum thyroid hormone and high-frequency ultrasound.When the diagnosis is difficult,fine-needle aspiration (FNA) is carried to differentiate benign and malignant nodules.In clinical practice,approximately 20％ of FNA-derived cytology reports can not meet the standard of benign or malignant.Some specific molecular biomarkers are applied to the derivative detection of FNA,which achieve considerable progress and improve the preoperative diagnostic rate.

Objective To investigate the potential complications of renal transplant patients, to develop appropriate treatment programs to reduce the incidence. Methods Clinical data of 42 patients with renal transplantation were retrospectively analyzed. Blood type of the donors and recipients were same in 32 cases; Blood type of the donors was 0 and recipients blood type was A,3 cases;Donors blood type was 0 and recipients blood type was B,2 cases; Donors blood type was O and recipients blood type was AB,4 cases; Donors blood type was B and recipients blood type was AB,lease. Results In alll cases, there were acute rejection in 2 cases,pulmonary infection in 2 cases, wound infection in 1 case,urinary leakage in 1 case,urinary tract infection in 2 cases.42 cases were all cured up. One patient lost kidney function and required dialysis therapy 4 years after kidney transplantation, the remaining 40 patients were good. Conclusion Early detection and timely management of complications of renal transplantation played a very important role in improving the survival rate.

Objective:To perform a meta-analysis of randomized controlled trials ( RCTs) in multiple sclerosis ( MS) patients to evaluate the efficacy and safety of alemtuzumab.Methods: We searched PubMed,EMBASE,the Cochrane Library and so on up to February 2015 using the keywords:′multiple sclerosis′or ′MS′and the drug names:alemtuzumab.Two authors independently selected the articles and extracted the data.We performed meta-analysis using Review Manager ( RevMan) version 5.3 software.Results:Three RCTs with a total of 1 695 patients were selected.Compared to the interferon beta,the number of gadolinium-enhancing lesions ( odds ratio (OR)=0.33,95% Confidence interval (CI)=[0.23,0.48],P<0.000 01),the cumulative probability of sustained disability (Or=0.51,95%CI=[0.38,0.69],P<0.000 1) and the proportion of patients who had at least one relapse of MS(Or=0.42,95%CI=[0.34,0.52],P<0.000 1) were significantly less in the alemtuzumab group,meanwhile the number of new T2-hyperintense lesions (Or=0.10,95%CI=[0.01,1.75],P=0.11) showed no significant difference.Comparing adverse events between two groups, alemtuzumab treatment did not increase the frequency of serious adverse events (Or=1.00,95% CI=[0.80,1.26],P=0.99) but increase the frequency of any adverse events (Or=2.29,95% CI=[1.40,3.75],P=0.001).Conclusion: Alemtuzumab is a relatively effective and safe treatment for MS.
