ObjectiveThe aim of this study is to investigate whether oral administration of collagen Ⅱ peptide (250-270)[C Ⅱ (250-270)]-cholera toxin B subunit (CTB)complex could effectively set up oral immune tolerance to collagen-induced arthritis (CIA) in mice. MethodsDBA/1 mice were divided into Ⅰ, Ⅱ, Ⅲ and Ⅳgroups. Group Ⅰ was normal control group. Collagen type Ⅱ emulsified in Freund's complete adjuvant were injected to mice of groups Ⅱ , Ⅲ and Ⅳ twice from the base of the tail. Mice of group Ⅲ were fed with C Ⅱ (250-270)-CTB covalent complex twice after the arthritis was developed. Mice of group Ⅳ were fed with C Ⅱ(250-270) and CTB mix at the 14th day after primary immunization. Visual scores and histopathologic scores of arthritis were recorded. The frequencies of arthritis between the groups were compared usingFisher's exact test. The clinical and histological severity of arthritis were analyzed by ANOVA.Results The frequencies of arthritis in groups Ⅰ , Ⅱ , Ⅲ and Ⅳ were 0, 100％, 100％ and 25％ respectively. Average accumulative scores of arthritis were 0, 5.0±1.7, 10.8±2.8 and 1.0±2.0 respectively. Average accum-ulative histopathological scores of arthritis were 0, 16±8, 32±13 and 7±6 respectively. Conclusion Oral administration of C Ⅱ (250-270) and CTB mix in arthritis mice after C Ⅱ immunization can suppress the onset and severity of arthritis. Oral administration of C Ⅱ (250-270)-CTB covalent complex in the acute stage of arthritis can accelerate arthritis.

Objective To investigate the inhibitory effects of Argatroban on the instant bloodmediated inflammatory reaction(IBMIR)after islet transplantation.Methods Rat islets were isolated and purified rat islets,and were divided into blank control group,control group and experimental group.In the control group,the blood and the islets were directly mixed,and in the experimental group the Argatroban was added to the mixture based on the control group.while the blank control group was added with blood alone without the islets.Each group was reacted at 37℃for 60min,and then the content was filtered through trap valve of 70 μm.The residual thrombus and tissues were filtered by the trap valve in both the experimental and control groups,detected by the thinprep cytologic test(TCT),and the filtrate received blood routine test,and the function of islet was determined using insulin releasing test.Results The number of blood platelets,white blood cells,mononuclear cells,and lymphocytes percentage in the experimental group were significantly higher than in the control group after 60 min(P＜0.05).Under the environment of the high and low concentrations of glucose,the insulin release in experimental group was significantly increased as compared with the control group,and the insulin release index of former was 2.25±0.18,significantly higher than that of the latter 3.36±0.18(P＜0.05).The residual thrombus and tissues had few islet cells in the control group,the structure was damaged seriously,the capsule was not intact,and there were a large mumber of micro-thrombosis around the islets formed by red blood cells.But there were a large number of islet cells in the experimental group.the structure was intact in a mass,and no obvious micro-thrombosis around the islets was found.Conclusion Argatroban can effectively inhibit IBMIR in vitro,and alleviate the damage to the islet cells.

A double targets of high throughput screening model for xanthine oxidase inhibitors and superoxide anion scavengers was established. In the reaction system of xanthine oxidase, WST-1 works as the probe for the ultra oxygen anion generation, and product uric acid works as xanthine oxidase activity indicator. By using SpectraMax M5 continuous spectrum enzyme sign reflectoscope reflector, the changes of these indicators' concentration were observed and the influence factors of this reaction system to establish the high throughput screening model were studied. And the model is confirmed by positive drugs. In the reaction system, the final volume of reaction system is 50 μL and the concentrations of xanthine oxidase is 4 mU x mL(-1), xanthine 250 μmol x L(-1) and WST-1 100 μmol x L(-1), separately. The Z'-factor of model for xanthine oxidase inhibitors is 0.537 4, S/N is 47.519 9; the Z'-factor of model for superoxide anion scavengers is 0.507 4, S/N is 5.388 9. This model for xanthine oxidase inhibitors and superoxide anion scavengers has more common characteristics of the good stability, the fewer reagent types and quantity, the good repeatability, and so on. And it can be widely applied in high-throughput screening research.

Objective: To compare the effects of Cox proportional hazard regression model (Cox model) and extreme gradient boosting model ( XGBoost model ) on the prediction of the mortality of acute paraquat poisoning (APP). Methods: The APP cases admitted to Qingdao Eighth People's Hospital and Shandong Provincial Hospital from January 1st of 2018 to December 1st of 2020 was recruited and divided into a training group and a verification group by a random number table. The Cox model and XGBoost model were established to select the predictors for APP mortality. Receiver operating characteristic ( ROC ) curve was drawn to analyze the predictive power of the two models, and the calibration was evaluated using Hosmer-Lemeshow test. Results: Totally 150 APP cases were recruited. There were 75 cases each in the training group and in the verification group, with 52 and 55 cases died respectively, accounting for 69.33% and 73.33%. The Cox model showed that paraquat intake, the time from taking poison to seeing a doctor, the time for the first perfusion, the time for the first vomiting, aspartate aminotransferase, alanine aminotransferase, serum creatinine, blood urea nitrogen, white blood cell, lactic acid, creatine kinase isoenzymes, glucose, serum calcium and serum potassium were the predictors of APP mortality ( all P<0.05 ). The XGboost model showed that the predictive power of the factors in a descending order were the time from taking poison to seeing a doctor, the time for the first vomiting, the time for the first perfusion, lactic acid, white blood cell, paraquat intake, serum creatinine, serum potassium, serum calcium, creatine kinase isoenzymes, glucose, aspartate aminotransferase, blood urea nitrogen and alanine aminotransferase. The area under curve ( AUC ) of the XGBoost model for predicting was 0.972, which was greater than 0.921 of the Cox model ( P<0.05 ). The predicted results of the Cox model and XGBoost model were consistent with the actual situation ( P>0.05 ). Conclusion The Cox model and XGBoost model are consistent in predicting the mortality of APP, but the latter is better.

Objective To explore the application value of Golgi protein-73 (GP73)and AFP in single and combining form in the diagnosis of primary hepatocelluar carcinoma (PHC).Methods Eighty PHC,65 liver cirrhosis,54 chronic hepatitis patients and 50 controls were selected in the First Afiliated Hospital in Xinjiang Medical University from May to September in 2011,GP73 was detected by ELISA and AFP was measured by clinical chemiluminescence.The sensitivity and specificity of each parameter in single and combining form were evaluated.Results Serum GP73 in PHC group 282.0(163.6-366.7) μg/L,liver cirrhosis group 211.8(107.5-295.7) μg/L,chronic hepatitis group 100.3(61.8-191.3) μg/L and control group 58.3(43.4-83.6) μg/L was tested by Kruskal-Wallis(H =106.6,P ＜0.01).GP73 in PHC group was further compared with liver cirrhosis group,chronic hepatitis group and control group using MannWhitney test,significance was found,(U was 1796.0,826.5,154.0,respectively,all P ＜0.01).In the single form,the sensitivity of GP73 [82.5％ (66/80)] was higher than AFP [66.3％ (53/80),x2 =4.65,P ＜0.05],but the specificity of GP73 [63.3％ (107/169)] was lower than AFP [88.7％ (150/169),x2 =28.91,P ＜0.05].There were 27 AFP negative cases in PHC group,but 22 of them were GP73 positive,making the positive rate of GP73 [81.5％ (22/27)] in PHC patients with AFP negative.There were 14 GP73 negative cases of in PHC group,but 9 of them were AFP positive,making the positive rate of AFP [64.3％ (9/14)] in PHC patients with GP73 negative.In series diagnostic test,the specificity of combining form [95.9％ (162/169)] was higher than AFP [88.7 ％ (150/169),x2 =6.00,P ＜ 0.05] ; in parallel diagnostic test,the sensitivity of combining form [93.8％ (75/80)] was higher than GP73 [82.5％(66/80),x2 =4.84,P ＜0.05].In PHC group,52 patients with HBV infection,10 patients with HCV infection and 18 patients without virus infection,GP73 was 309.5 (170.5-370.5) μg/L,351.0 (274.7-397.9) μg/L and 210.1 (156.8-306.7) μg/L,respectively,no significance was found (H =4.0,P ＞0.05).Conclusion GP73 and AFP have a complementary feature of sensitivity and specificity in the early diagnosis of PHC,some PHC cases with AFP negative can be avoided missing efficiently by parallel diagnostic test.
