Objective:To investigate the effect of tofacitinib on early atherosclerosis of patients with systemic lupus erythematosus and explore the possible relationship between lupus nephritis and early atherosclerosis of systemic lupus erythematosus.Methods:Sixteen 8-week-old female MRL/lpr mice with a body weight of 20~25 g were selected and randomly divided into the treatment group and placebo group, with 8 mice in each group. 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.

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.

Objective To investigate the effect of ethanol on level of the main hippocampal subtype of muscarinic receptor(M1)in mice,and evalu?ate whether the content change on this receptor could be linked with alterations in cognition,so as to further reveal the mechanism of brain damage in?duced by ethanol. Methods Sixty female mice were randomly divided into four groups. The model mice were induced by intragastric administration of ethanol at dose of 8%,16%,and 32%respectively of 0.2 mL/10 g for 8 weeks according to the protocol,and control group were treated with intra?gastric administration of distilled water. The capability of learning and memory were examined by Morris water maze,and ELISA method was used to measure the M1 receptor content in hippocampus in each group of mice. Results Compared with first day,the mean escape latency period on the fifth day was significantly shortened in each group. There was no significant difference between ethanol and control group for the mean escape latency period on the fifth day. Compared with the control group,the active time in the target quadrant was significantly shortened in 16%and 32%ethanol group. M1 receptor content in hippocampus formation was significantly decreased in all the ethanol group mice. The ethanol concentration was nega?tive correlated with the M1 receptor content. Conclusion Chronic alcoholism can induce the memory impairment in mice,which might be associat?ed with the low level of M1 receptor subtype in hippocampus of mice.
