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 Islet transplantation has been an effective method for diabetes mellitus. The quality of donor pancreas is important for successful islet isolation. In this study, we evaluated expanded criteria donor usability based on the warm ischemic time, fatty pancreas and perfusion injury. Methods The marginal pancreases include those from cardiac death donor, fatty pancreas and edema pancreas from perfusion injury. Islets were isolated and purified using a modified University of Minnesota method. Islet yield and purity was determined by Dithizone (DTZ) staining and microscopic examination. Islet viability was assessed by AO/EB staining, and islet function was assessed by static glucose stimulation test. Results In the cardiac death donor group, the islet quality, viability, and in vitro function were similar when the warm ischemic time within 15 min. The quality and viability was decreased when the warm ischemic time beyond 30 min, but the function remained well. With 45 min warm ischemic time, insulin release index was decreased significantly. The islet quality, viability, and in vitro function from severe obesity group and severe edema group were decreased obviously. Conclusion Donor factors play a vital role in pancreas transplant outcomes. We concluded that pancreas severe obesity, severe edema and pancreas from cardiac donors (warm ischemic time >30 min) are unsuitable for islet isolation.
