Objective:To analyze the serum levels of integrin-associated proteins (CD47) in patients with rheumatoid arthritis (RA), and to explore its association with disease activity and bone destruction in RA.Methods:Serum and clinical data were collected from 65 RA patients and 25 healthy subjects. RA patients were grouped into low, moderate, and high bone erosion groups according to 7-joint ultrasonography score (US7). The levels of serum CD47, thrombospondin-1 (TSP-1) and receptor activator of nuclear factor-κB ligand (RANKL) were measured by enzyme-linked immunosorbnent assay (ELISA) in patients with RA and healthy subjects. The statistical analysis was carried out with independent t-test, analysis of variance, nonparametric rank sum test, pearson or Spearman correlation and logistic regression. Results:① The Serum levels of CD47, TSP-1, and RANKL were higher in the RA group than in the healthy controls ( P<0.01). ② In RA patients, serum CD47 level was positively correlated with disease course ( r=0.301, P<0.05), C-reactionprotein (CRP)( r=0.316, P<0.05), number of tender joints (TJC) ( r=0.254, P<0.05), number of swollen joints (SJC) ( r=0.316, P<0.05), disease activity score in 28 joints (DAS28) ( r=0.255, P<0.05), RANKL ( r=0.252, P<0.05) and TSP-1 ( r=0.260, P<0.05). Serum TSP-1 level was positively correlated with CRP ( r=0.299, P<0.05), TJC ( r=0.335, P<0.01), DAS28 ( r=0.315, P<0.05), RANKL ( r=0.305, P<0.05). ③ The disease course [ OR(95% CI)=1.048(1.033, 1.017)] and TSP-1 [ OR(95% CI)=1.013(1.000, 1.026)] were independently relevant factors affecting bone destruction. Conclusion:CD47 levels is significantly higher in RA patients than in healthy controls, and is associated with disease activity and bone destruction. CD47 may be involved in the bone destruction process of RA by acting on TSP-1.

The treatment group diluted tofacitinib by normal saline, and given at a dose of 10 mg·kg -1·d -1, and the placebo group (starch tablets) administered the medication in the same way as the treatment group for a total of 8 weeks. The ELISA method was applied to detect serum anti-dsDNA antibody levels in the two groups of mice. Bradford method protein concentration was used to determine the level of urine protein in mice. Automatic biochemical analyzer was used to detect blood lipids, urea nitrogen, serum creatinine, complement C3, complement C4 levels. Western blotting was used to determine the protein expression levels of monocyte chemoattractant protein-1 (MCP-1), non-receptor protein tyrosine kinase family 1 (JAK1), signal transducer and activator of transcription 1 (STAT1) and signal transducer and activator of transcription 2 (STAT2) in aortic and kidney tissues. After the aortic arch section were prepared, oil red O was used to stain the sections, and the vascular plaque area and intimal thickness were evaluated by ImageJ software. The kidneys were dissected and stained with HE, and the active lesions of lupus nephritis were evaluated using the glomerular activity scoring system.

The urine protein levels in the two groups were positively correlated with LDL, TC, TG, aortic plaque area and aortic intimal thickness ( r=0.67, P=0.004; r=0.68, P=0.004; r=0.53, P=0.033; r=0.80, P<0.001; r=0.74, P=0.001), and negatively correlated with HDL ( r=-0.57, P=0.021). Conclusion:The severity of lupus nephritis is correlated with atherosclerosis and dyslipidemia in the early stage of systemic lupus erythematosus. Tofacitinib may reduce the degree of early arteriosclerosis and lupus nephritis in MRL/LPR mice, and reduce blood lipid levels, which may be effective in improving the prognosis of SLE and improving the survival rate of patients.

ObjectiveThe hygroscopic properties of Mume Flos decoction pieces were studied from the perspectives of macroscopic[water activity(Aw)] and microscopic(water molecular mobility), which provided a theoretical basis for the determination of the safe storage moisture content. MethodAdsorption isotherm of Mume Flos decoction pieces was obtained by static weighing method, and seven common hygroscopic models were fitted and estimated. The best model was selected according to the principle that determination coefficient(R2) was closer to 1, residual sum of squares(RSS) was closer to 0 and Akaike information criterion(AIC) was smaller. According to the optimal model, the absolute and relative safe moisture contents of Mume Flos decoction pieces at 25, 35, 45 ℃ was calculated. Low-field nuclear magnetic resonance(LF-NMR) was used to measure the water molecular mobility in the hygroscopic process of Mume Flos decoction pieces. ResultThe best model to describe the adsorption isotherm of Mume Flos decoction pieces was the Peleg model. According to the model expression, the absolute safe moisture contents of Mume Flos decoction pieces at 25, 35, 45 ℃ were 9.59%, 7.96% and 7.68%, and the relative safe moisture contents were 13.05%, 11.99%, 11.77%, respectively. Mume Flos decoction pieces all contained two water states during the process of hygroscopic absorption at different temperatures, namely bound water T21 and free water T22. During the process of hygroscopic absorption, bound water had the largest increase in peak area. The sum of peak areas of the bound water and free water had a good linear relationship with the moisture contents, and the R2 were 0.959 9, 0.911 8 and 0.974 7 at 25, 35, 45 ℃, respectively. When Aw<0.57, T21 did not change, and the water molecular mobility remained unchanged. When Aw>0.57, T21 showed an increasing trend, and the water molecular mobility increased. The moisture contents of Mume Flos decoction pieces were 8.44%, 6.81% and 6.25% when the water molecular mobility increased at 25, 35, 45 ℃, respectively. ConclusionCombined with the theory of water activity and water molecular mobility, 6.25% is recommended as the safe storage moisture content of Mume Flos decoction pieces, this study can provide reference for determining the safe storage moisture content of other decoction pieces.
