OBJECTIVES: To analyze the molecular mechanism of Xixian Pills for treatment of rheumatoid arthritis (RA). METHODS: Forty-eight rats were randomized into 6 groups (n=8), including a normal control group, a collagen-induced arthritis (CIA) model group, 3 Xixian Pills treatment (200, 400 and 800 mg/kg) groups, and a Tripterygium glycosides tablet (TGT) treatment group. In the latter 4 groups, the rats were treated with daily gavage of Xixian Pills or TGT 2 weeks after CIA modeling for 3 consecutive weeks. The differentially expressed proteins in high-dose Xixian Pills group and the model group compared with the normal control group were screened based on the tandem mass spectrometry tag (TMT) technology, and the core targets and signaling pathways were analyzed. The immune cell infiltration and gene expression data were analyzed using ggplot2 and tidyverse packages, and the correlation coefficients between the core targets and the immune cells were calculated. RESULTS: The CIA rats showed significantly increased serum levels of TNF-α and IL-6 and lowered serum IL-10 level. Treatments with high- and medium-dose Xixian Pills and TGT all significantly reduced serum TNF‑α and IL-6 and increased IL-10 levels in CIA rats. Proteomic analysis identified 160 differential proteins between the model group and high-dose Xixian Pills group, and the core targets included CCL5, STAT1, GZMB and IL7R. The areas under the ROC curve of CCL5 and STAT1 were both greater than 0.9. Immunohistochemical and immunofluorescence staining revealed increased levels of CCL5 and STAT1 in the ankle joints of CIA rats, which were significantly decreased after treatment with Xixian Pills. CONCLUSIONS Treatment with Xixian Pills offers protection of the joints in CIA rats possibly by inhibiting joint inflammation via regulating protein expressions of CCL5 and STAT1.

Objective:To analyze the correlation between blood glucose index and peripheral neuropathy in type 2 diabetes patients under continuous blood glucose monitoring.Methods:A total of 110 patients with type 2 diabetes admitted to the Lu′an Hospital Affiliated to Anhui Medical University from November 2022 to January 2024 were retrospectively observed, and the blood glucose indexes of patients were monitored by continuous glucose meter [glucose time in range (TIR), mean blood glucose (MBG), estimated hemoglobin A 1c (eHbA 1c), blood glucose standard deviation (SD), coefficient of variation (CV), largest amplitude of glycemic excursions (LAGE), mean amplitude of glycemic excursions (MAGE), means of daily differences (MODD), etc ]. All patients with type 2 diabetes were grouped according to whether they had peripheral neuropathy or not, and were divided into the developing group and the non-developing group. General data and blood glucose indexes of the two groups were collected and sorted out. Receiver operating characteristic (ROC) curve was used to analyze the value of various blood glucose indicators in predicting peripheral neuropathy in patients with type 2 diabetes. Spearman correlation analysis was also used to evaluate the correlation between blood glucose index and peripheral neuropathy. Results:The disease course, TIR, MBG, eHbA 1c, SD, CV, LAGE, MAGE and MODD of the occurrence group were significantly different from those of the non-occurrence group (all P<0.05). By plotting the ROC curve, It was found that the area under the curve (AUC) of TIR, MBG, eHbA 1c, SD, CV, LAGE, MAGE and MODD predicting peripheral neuropathy in patients with type 2 diabetes were 0.942, 0.840, 0.705, 0.759, 0.819, 0.813, 0.857 and 0.677, respectively. The AUC of the combined prediction was 0.971(95% CI: 0.946-0.997), which was higher than that of the single indicator (all P<0.05). Spearman correlation assessment showed a negative correlation between TIR and peripheral neuropathy ( r=-0.738, P<0.05). MBG, eHbA 1c, SD, CV, LAGE, MAGE and MODD were positively correlated with peripheral neuropathy ( r=0.554, 0.376, 0.452, 0.490, 0.527, 0.625, 0.272, all P<0.05). Conclusions:Based on continuous blood glucose monitoring, the blood glucose index of type 2 diabetes patients is closely related to peripheral neuropathy, and the above blood glucose index can accurately predict peripheral neuropathy, providing a reference for reducing or preventing the occurrence of peripheral neuropathy.

Objective To use the GEO dataset and bioinformatics techniques,such as LASSO logistic regression,ssGSEA,and WGCNA,to screen for RA diagnostic markers and investigate the impact of earthly flavonoids in Smi-lax glabra Roxb.on specific immune cell infiltration,to screen for rheumatoid arthritis(RA)diagnostic markers on specific immune cell infiltration and to analyze the combination of flavonoids in Smilax glabra Roxb.and diagnostic markers.Methods The normal control group and RA gene chip were obtained from the Gene Expression Omnibus database.The R 4.3.0 WGCNA software package was used to integrate and analyze the dataset,identify co-expres-sion modules and associated trait information,and screen key modules closely related to RA.LASSO regression a-nalysis was performed using the glmnet package in R to identify characteristic genes for RA.The area under the re-ceiver operating characteristic(ROC)curve was used to evaluate the diagnostic value of the characteristic genes in RA.The gene expression data of the normal control group and RA group were subjected to quantitative immune cell infiltration analysis using the GSVA,limma,and GSEABase packages in R.The chemical components of earth-worm flavonoids in Smilax glabra Roxb.were analyzed based on UHPLC-Q-Exactive Orbitrap MS.The correlation between flavonoids and characteristic genes was assessed through molecular docking.Results The LASSO regres-sion algorithm selected 5 characteristic genes(apolipoprotein D,zinc finger and BTB domain containing 16,C-C chemokine receptor type 5,matrix metalloproteinase 1,coronin-1A).The area under ROC curve of all 5 character-istic genes was greater than 0.85,which exhibited positive correlations with various immune cells.Twenty earth-worm flavonoids of Smilax glabra Roxb.were identified using UHPLC-Q-Exactive/MS,and Mulberrin and Neobavaisoflavone were well combined with 5 immune characteristic genes.Conclusion Flavonoids compounds of Smilax glabra Roxb.have good combination with RA immune characteristic genes,providing a scientific basis for RA immunomodulation therapy and early diagnosis.

Objective To explore the causal relationship between rheumatoid arthritis(RA)and iron deficiency a-nemia(IDA)in European population by two-sample Mendelian randomization analysis.Methods The single nu-cleotide polymorphisms(SNPs)of RA and IDA were analyzed using public genome-wide association studies(GWAS).The inverse variance weighting method(IVW)was used as the main analysis method to evaluate the causal effect of RA on IDA.MR-Egger method,weighted median method(WM),weighted model method and simple model method were used as regression supplements to evaluate the robustness of sensitivity analysis results.The het-erogeneity function was used to calculate the P-value to test the heterogeneity,and the intercept term intercept was used to test the level pleiotropy.Results In the FINNGEN database at the genome-wide level,strong-related SNPs that removed linkage disequilibrium and met the P＜5.0 × 10-8 by Mendelian randomization analysis were select-ed.After integrating exposure and outcome data,31 SNPs were obtained as the final effective instrumental variables.IVW showed that RA was a risk factor for IDA(the risk of IDA in RA patients was 1.064 times higher than that in non-RA patients,OR=1.064,95％CI:1.028-1.103).The weighted median method and MR-Egger method re-sults supported the positive correlation between RA and IDA.The intercept value was close to 0,indicating that there was no horizontal pleiotropy between exposure and outcome.The heterogeneity function's P＜0.05 indicated that there was heterogeneity between exposure and outcome,but the random effect model test showed P＜0.05,indi-cating that even if there was heterogeneity in causality,the overall trend was stable.Conclusion RA is a risk factor for IDA,and there is a positive correlation between RA and IDA.
