Objective To explore the expressions of endoplasmic reticulum stress (ERs) related factors including inositol requiring enzyme-1α(IRE1αα),p-IRE1 α,c-jun N-terminal Kinase(JNK),and p-JNK in rats with non-alcoholic fatty liver disease,and to investigate the effect of intervention with glucagon-like peptide 1 (GLP-1) analogue.Methods Forty male Sprague-Dawley rats were divided into normal chow group(n =15) and high-fat diet group(n=25).After 12 weeks,5 rats of each group were used to assess the establishment of rat models with non-alcoholic fatty liver disease.Then the high-fat diet group rats were divided into high-fat diet group (HF,n =10) and GLP-1 group(HG,n=10) and treated with normal saline and GLP-1 analogue for4 weeks respectively.Body weight and biochemical markers in rats were measured.The expressions of IRE1α,p-IRE1α,JNK,and p-JNK were measured by Western blot.Results Compared with the NC group,the levels of body weight,plasma triglyceride (TG),total cholesterol (TC),low density lipoprotein-cholesterol (LDL-C),alanine aminotransferase (ALT) and aspartate aminotransferase (AST) in HF group were significantly higher (all P ＜ 0.01),high density lipoprotein-cholesterol(HDL-C) was decreased(P＜0.01),and p-IRE1 α/IRE1 α and p-JNK/JNK were increased(P＜0.05 and P＜0.01).After GLP-1 treatment,body weight,plasma TG,TC,LDL-C,AST,ALT in HF group were significantly lowered(P＜0.05 or P＜0.01),HDL-C was increased(P＜0.01),p-IRE1 α/IRE1 α and p-JNK/JNK were decreased (P＜0.05 and P＜0.01).Conclusion GLP-1 analogue may improve hepatic steatosis via regulating ERs related IRE1 α-JNK signaling pathway.

Objective To investigate the relationship between with or without non?alcoholic fatty liver disease(NAFLD) and diabetic retinopathy(DR) in type 2 diabetes mellitus(T2DM)?Methods Clinical and laboratorial data of 517 cases T2DM hospitalized patients were collected,and the patients were divided into two groups according to if the NAFLD was complicated or not?Group A was T2DM with NAFLD and group B was T2DM without NAFLD?The general information and the laboratorial checking results were Compared, then various index were used as the independent variable, DR was used as the dependent variable for Logistic regression analysis?Results (1)In the 517 cases of T2DM patients,the incorporative rate of the NAFLD was 65?7%(349/517)?(2)Compared with group B,the levels of body mass index(BMI),insulin resistance index (HOMA?IR),glutamyltransferase(GGT),alanine aminotransferase(ALT),aspartate aminotransferase(AST), triglyceride(TG),total cholesterol(TC),low?density lipoprotein cholesterol(LDL?C) and uric acid(UA) for group A were significantly increased, while the high?density lipoprotein cholesterol ( HDL?C ) level was significantly decreased?All the differences were statistically significant( P<0?05)?( 3) Logistic analysis showed that the duration of the extension,hypertension,the increasing level of NAFLD,LDL?C were the risk factors of DR?Even though excluded the influence of duration,high blood pressure and LDL?C level,NAFLD was still the risk factor for T2DM complicated by the DR( OR=2?176,95% CI ( 1?354,3?199) )?Conclusion NAFLD and DR are closely related, so early diagnosis and intervention of NAFLD may prevent the occurrence and development of DR.

Objective:To explore the interaction between gossypol and human serum albumin ( HSA) . Methods:The interaction of gossypol and HSA under physiological conditions was studied by fluorescence spectroscopy, and the molecular docking software was used to simulate the interaction. Results:The binding constant of gossypol and HSA at 293K and 303K was 2. 390 6 × 105 L·mol-1 and 3. 576 8 × 103 L·mol-1 , respectively. There was one binding site on HSA for gossypol. Hydrogen bond and Van Der Waals inter-actions were involved in the binding process. The binding of gossypol and HAS was closer to tyrosine residue in HSA. The molecular simulation analysis verified the above results. Conclusion: The gossypol-induced fluorescence quenching of HSA belongs to a static quenching procedure.

Objective To explore the difference of clinical features and laboratory indexs with different vasovagal responses in(head-up) tilt test(HUT) in children with vasovagal syncope(VVS).Methods Forty consecutive children diagnosed with VVS by HUT were analyzed.The vasovagal responses were divided into vasodepressor,cardioinhibitory and mixed patterns.The distribution and different clinical features and laboratory indexs of different response patterns in the VVS were studied.Results The most common vasovagal response was vasodepressor.There was no significant difference in their clinical features,including the motivation,presymptom,frequency and duration of syncope,baseline heart rate and blood pressure,and serum electrolytes among the children with different vasovagal respon-ses.Conclusion Vosodepressor response is the most common hemodynamic pattern in vasovagal syncope in children.

High-fat diet-induced insulin resistance rat model was assessed by euglycemic-hyperinsulinemic clamp technique.Compared with the control group,the vaspin mRNA expression in adipose tissue was significantly decreased in insulin resistant rats induced by high-fat diet( P＜0.05 ),which was increased by metformin( P＜0.05 ).These data indicate that metformin may ameliorate insulin resistance in rats via upregulating vaspin mRNA expression.

Objective To study the main risk factors related to the incidence of tuberculosis in China and to provide di -rections and basis for the protection of tuberculosis .Methods The results of 25 studies on the main risk factors of tubercu-losis of Chinese people from 2000 to 2012 were analyzed by meta-analysis method .Results The pooled odds radio values and 95%CI of history of exposure to pulmonary tuberculosis , smoking, marriage, contact with people, Bacille Calmette-Guerin (BCG)vaccination scar, BCG vaccination, low body mass index(BMI) , family history of tuberculosis, exposure to dust and to chemical fumes under working conditions were as follows:3.14(2.74-3.59),1.23(1.14 -1.33),3.05 (2.10-4.45),2.08(1.76-2.26),0.39(0.32 -0.47),0.58(0.46 -0.73),2.95(2.40 -3.64),2.56(1.82 -3.59),2.58(2.04-3.26),and 4.81(1.99-11.60).Conclusion Then History of exposure to pulmonary tuberculosis , smoking, marriage, contact with people , low BMI, family history of tuberculosis , exposure to dust and to chemical fumes under working conditions are considered to be the risk factors of pulmonary tuberculosis .While BCG vaccination scar and BCG vaccination are considered to be the protective factors of pulmonary tuberculosis .

Suitable pretreatment of biological samples can truly reflect the role of law of the measured components played in the body and will provide experimental evidence for the studies on metabolic process, material basis of efficacy, mechanism of action, pharmacology, toxicology and the others. Biological samples include blood, urine, hair, tears, etc. There are also many samples processing methods, such as the direct protein precipitation, liquid-liquid extraction and solid phase extraction and so on. These methods could be used alone or combined.
