Anti- inflmmatory effects of ferulofen(FL)and its mechanisms were studied. In the rat carrageenin pleurisy, FL produced a dose-related reduction of exudate volume, protein contents and leucocyte numbers in the exudate. FL also reduced activity of ?-glucuronidase in the exudate only in higher dose 3 h after carrageenin. These results suggest that FL has a marked anti-inflammatory action and its mechanisms may be similar to indomethacin. Ia vitro, FL caused a dose-dependent inhibition of hydrogen peroxide release from rat peritioneal macrophages ( M0 ) stimulated by opsonized zymosan. It suggested that its anti-inflammatory mechanisms may also relate to inhibitting cell activation. ?-receptor agonist ( Isoproterenol, ISO), in a ineffective dose, synergized with FL in inhibitting M H2O2 release and the synergic mechanism remains to be established.

Objective:To construct a novel cuproptosis-related gene signature (CRGS) for prediction of prognosis, immunotherapy response and drug sensitivity in patients with hepatocellular carcinoma (HCC).Methods:Data materials for this study were obtained from the international cancer genome consortium (ICGC), the cancer genome atlas (TCGA) database and Migort210 database, and protein expression profiles were obtained from the human protein atlas image classification database. Based on the TCGA cohort, the least absolute shrinkage and selection operator algorithm was applied to construct the CRGS and calculate the risk score for each HCC patient. HCC patients were grouped according to the median risk score: HCC patients in the TCGA cohort were divided into a high-risk group TCGA and a low-risk group TCGA with 184 cases in each group; HCC patients in the ICGC cohort were divided into a high-risk group ICGC and a low-risk group ICGC with 116 cases in each group. Patients in the Migort210 cohort were divided into a responder group ( n=68) and a non-responder group ( n=230) based on their response to immunotherapy. We assessed the value of CRGS in predicting the prognosis of HCC patients in the TCGA cohort and validated whether CRGS could be used to predict the prognosis of HCC patients in the ICGC dataset. To explore the role of CRGS in predicting immunotherapy response and drug sensitivity in HCC patients based on data from the TCGA cohort, and to apply the Migort210 immunotherapy cohort to validate the clinical value of CRGS in predicting immunotherapy in malignant tumors. Results:CRGS consists of four copper death-related genes: GLS, CDKN2A, LIPT1, and DLAT. Patients in the high-risk group TCGA had lower overall survival (OS), disease-specifical survival, and progression-free interval than those in the low-risk group TCGA (all P<0.01). OS of patients in the high-risk group ICGC was lower than that in the low-risk group ICGC ( P=0.022). Multivariate Cox regression analysis showed that CRGS was an independent risk factor for poor prognosis in HCC patients (TCGA: HR=2.991, 95% CI: 1.781-5.049, P<0.001; ICGC: HR=4.621, 95% CI: 1.685-12.674, P=0.033). Risk scores were positively correlated with the expression levels of CTLA4, PDCD1, CD80 and HLLA2 (all P<0.001). Patients in the high-risk group TCGA had lower tumor immune dysfunction and rejection scores than those in the low-risk group TCGA [-0.04(-0.07, -0.02) vs. -0.02(-0.04, 0) points], and the difference was statistically significant ( P<0.001). Patients in the responder group had a higher risk score than the non-responder group [1.70 (1.56, 1.90) vs. 1.63 (1.52, 1.80)], with a statistically significant difference ( P<0.05). The half-inhibitory concentrations (IC 50) for sunitinib, rapamycin and etanercept were higher in the high-risk group TCGA than that in the low-risk group TCGA, while the IC 50 for erlotinib was lower than that in the low-risk group TCGA, and the differences were all statistically significant (all P<0.001). Conclusion:The CRGS might be served as a potential biomarker to predict the prognoses, immunotherapy response, and drug sensitivity of patients with HCC.

ObjectiveTo investigate the effect of Xinfeng capsules on immunoinflammatory indicators in patients with rheumatoid arthritis (RA) due to spleen deficiency and dampness exuberance. MethodA total of 102 patients were randomly divided into control group and observation group according to the random number table method, with 51 cases in each group. All patients were treated with methotrexate tablets, while those in the observation group received additional Xinfeng capsules. The course of treatment in both groups was 12 weeks. The 28-joint disease activity score (DAS28), visual analogue scale (VAS) scores, morning stiffness time, erythrocyte sedimentation rate (ESR), high-sensitivity C-reactive protein (hs-CRP), rheumatoid factor (RF), anti-cyclic citrullinated peptide (anti-CCP) antibody, vascular endothelial growth factor (VEGF), and serum amyloid A (SAA) of the two groups before and after treatment were compared. The efficacy and incidence of adverse events were compared between the two groups. The Apriori association rule model and random walk model were constructed to evaluate the effect of Xinfeng capsules in improving hs-CRP, ESR, RF, SAA, VEGF, and anti-CCP. ResultThere were no dropouts in this study. There was no statistical difference in the indicators between the two groups before treatment. After 12 weeks of treatment, the total effective rate in the observation group was 90.19% (46/51), which was higher than 74.51% (38/51) in the control group (χ2=4.320,P<0.05). DAS28, VAS score, and morning stiffness time in the observation group were improved compared with those in the control group (P<0.05). Apriori association rule model results showed that the application of Xinfeng capsules in the observation group had a strong correlation with the reduction of RF, ESR, hs-CRP, SAA, and VEGF. The results of the random walk model showed that the improvement coefficients of hs-CRP, ESR, RF, SAA, and VEGF in the observation group were all better than those of the control group, and the improvement coefficient of anti-CCP in the control group was better than that of the observation group. The improvement degree of hs-CRP, ESR, RF, SAA, and VEGF in the observation group was superior to that of the control group (P<0.05). The incidence of adverse reactions in the observation group was lower than in the control group (χ2=4.057,P<0.05). ConclusionOn the basis of the treatment with methotrexate tablets, Xinfeng capsules can effectively improve the immunoinflammatory level in RA due to spleen deficiency and dampness exuberance and reduce the incidence of adverse reactions.
