RESUMEN
OBJECTIVE: To determine whether moxibustion had an anti-inflammatory effect on rheumatoid arthritis (RA) by regulating Annexin 1 expression and interfering with the phospholipaseA2 signaling pathway. METHODS: Thirty male Sprague-Dawley rats were randomly categorized into five groups (six rats per group): blank control (CON) group, RA model (RA) group, moxibustion (MOX) group, Annexin 1 lentiviral intervention (RNAi-Anxa1) group, and Annexin 1 lentiviral intervention + moxibustion (RNAi-Anxa1 + MOX) group. The rats in the RNAi-Anxa1 and the RNAi-Anxa1 + MOX groups were injected with the lentiviral vector-mediated RNAi-Anxa1 into the rat foot pad. An experimental RA rat model was established by injecting Freund's complete adjuvant (FCA) into the RA, MOX, RNAi-Anxa1, and RNAi-Anxa1 + MOX groups. Rats in the MOX and RNAi-Anxa1 + MOX groups received moxibustion treatment. After modeling, using moxibustion "Shenshu (BL23)" and "Zusanli (ST36)", each point is 5 times, bilateral alternating, once a day, 6 times for a course of treatment, between the courses of rest for a one day. A total of three treatment courses were conducted. Both bilateral pad thicknesses were measured using Vernier calipers on experimental days 1, 7, 14, 21, and 28. The expression of cPLA2α signaling in the synovium of diseased joints was observed using Western blot. The pathology of the rat ankle synovium was observed using hematoxylin-eosin (HE) staining. Interleukin (IL)-1ß, IL-10, prostaglandin E2 (PGE2), and leukotriene B4 (LTB4) were detected using enzyme-linked immunosorbent assay. RESULTS: Moxibustion increased the levels of Annexin 1 and decreased the inflammatory response in rats with RA. After increasing the expression of Annexin 1, the phosphorylated expression of cPLA2α was inhibited, the serum levels of IL-1ß, PGE2, and LTB4 decreased, and the level of IL-10 increased. In moxibustion treated RA rats after the Annexin 1 lentiviral intervention, the serum levels of IL-1ß, PGE2, LTB4, and IL-10 were almost unchanged. CONCLUSION: Moxibustion enhanced the negative regulation of the cPLA2α signaling pathway, increased the synovial Annexin 1 expression, inhibited the cPLA2α signaling pathway, indirectly inhibited the expression of downstream inflammatory factors, and played a role in reducing inflammation.

OBJECTIVE: To test the hypothesis that moxibustion may inhibit rheumatoid arthritis (RA) synovial inflammation by regulating the expression of macrophage migration inhibitory factor (MIF)/glucocorticoids (GCs). METHODS: Fifty male Sprague-Dawley rats were randomly divided into five groups (n = 10 each): blank Control (CON) group, RA Model (RA) group, Moxibustion (MOX) group, MIF inhibitor (S,R)-3-(4-hydroxyphenyl)-4,5-dihydro-5-isoxazole acetic acid methyl ester (ISO-1) group, and Moxibustion + MIF inhibitor ISO-1 (MOX + ISO-1) group. Rats in the ISO-1 group and ISO-1 + MOX group were intraperitoneally injected with the inhibitor ISO-1. The rats in the RA group, ISO-1 group, MOX group, and ISO-1 + MOX group were injected with Freund's complete adjuvant (FCA) in the right hind footpad to establish an experimental RA rat model. In the MOX group and MOX + ISO-1 group, rats were treated with Moxa. The thickness of the footpads of the rats in each group was measured at three-time points before, after modeling and after moxibustion treatment. The contents of serum MIF, corticosterone (CORT), tumor necrosis factor-α (TNF-α) and interleukin-1ß (IL-1ß) were detected by enzyme-linked immunosorbent assay; and the contents of synovial MIF were detected by Western blot. Hematoxylin-eosin (HE) staining method was used to observe the pathological changes of synovial tissue under a section light microscope, and pathological scoring was performed according to the grading standard of the degree of synovial tissue disease. RESULTS: Moxibustion was found to reduce the level of MIF and alleviate inflammation in RA rats in this study. In addition, after inhibiting the expression of MIF, the level of CORT increased, and the level of TNF-α decreased. Treating RA rats with inhibited MIF by moxibustion, the level of CORT was almost unchanged, but the level of TNF-α further decreased. The correlation analysis data suggested that MIF was positively related to the expression of TNF-α and negatively correlated with the expression of CORT. CONCLUSION: Reducing MIF to increase CORT and decrease TNF-α by moxibustion treatment in RA. MIF may be a factor for moxibustion to regulate the expression of CORT, but the expression of TNF-α is due to the incomplete regulation of the MIF. This study added to the body of evidence pointing to moxibustion's anti-inflammatory mechanism in the treatment of RA.

Ethnopharmacological relevance: Astragalus polysaccharide (APS), the most biologically active ingredient of Astragali Radix, is used to treat diabetes mellitus (DM)-related chronic wounds in traditional Chinese medicine for several decades. This herb possesses an anti-inflammatory effect. Our study proved that APS can reduce excessive inflammation at the late phase of wound-healing in diabetic ulcers. Aim of the study: To clarify the molecular mechanism of APS in promoting wound-healing via reducing excessive inflammation in diabetic ulcers during the late stages of wound-healing. Methods and materials: The rat model of the diabetic ulcers was established via intraperitoneal injection of streptozocin (60 mg/kg). We detected the regulation of APS on diabetic ulcers by measuring wound-healing rates. Bioinformatics was used to predict the target genes of APS, and autodocking was used to predict the combination of APS and target genes. Immunohistochemistry, Enzyme-linked immunosorbent assay, Western blot, immunofluorescence staining, flow cytometry, and flow cytometric sorting were investigated. Results: The results demonstrated that APS promoted wound-healing and inhibited excessive inflammation at the late phase of wound-healing in diabetic rats. Mechanistic findings showed that APS promoted the expression of ß-catenin and Rspo3 while inhibiting the expression of NF-KB and GSK-3ß, which leads to the transformation of M1-type macrophages into M2-type macrophages and thus reducing excessive inflammation at the late phase of wound-healing in diabetic ulcers. Conclusion: We found an interesting finding that APS promoted the polarization of macrophages towards M2-type through the ß-catenin/NF-κB axis to reduce excessive inflammation at the late phase of wound-healing. Therefore, APS may be a promising drug for treating diabetic ulcers in clinic.

Objective To investigate the correlation between serum neuregulin 4(Nrg4)level and metabolic associated fatty liver disease(MAFLD)in patients with type 2 diabetes mellitus(T2DM).Methods A total of 240 T2DM patients admitted to the Department of Endocrinology of Second People's Hospital of Yichang from June 2021 to August 2022 were collected and divided into simple T2DM group(n=120)and MAFLD group(MAFLD,n=120).120 healthy individuals were selected as the normal control(NC)group.Results The serum Nrg4 decreased gradually from NC group,T2DM group to MAFLD group(P<0.05).Pearson correlation analysis showed that serum Nrg4 was negatively correlated with WC,HOMA-IR and hs-CRP(P<0.05),and positively correlated with HDL-C(P<0.05).Logistic regression analysis showed that Nrg4,WC,HOMA-IR and hs-CRP were the influencing factors of MAFLD.After adjusting for age,sex,smoking history,BMI,TC,TG,HDL-C,LDL-C,FPG,FIns,HbA1c and other factors,serum Nrg4 was still the influencing factor of MAFLD.Conclusion The decrease of serum Nrg4 is a risk factor for T2DM combined with MAFLD.
RESUMEN
OBJECTIVE: To evaluate the effects of moxa-burning heat stimulating acupoints Zusanli (ST36) and Shenshu (BL23) on macrophage migration inhibitory factor (MIF) and its related molecules which can provide scientific experimental basis for the clinical application of moxibustion treatment of rheumatoid arthritis (RA). METHODS: Thirty rabbits were randomly assigned to control group, RA model (established by injecting Freund's Complete Adjuvant) group (RA group) and RA model with moxibustion group [Moxa group, Zusanli (ST36) and Shenshu (BL23), 5 moxa pillars/day, 6 d × 3]. The expressions of MIF mRNA were evaluated with reverse transcription polymerase chain reaction; the apoptosis rates of macrophages were detected by erminal deoxynucleotidyl transferase-mediated dTUP nick end labeling; the expressions of related signal molecules were detected with immunohistochemical S-P method and the levels of IL-2 were detected with enzyme-linked immunosorbent assay. RESULTS: The expressions of MIF mRNA, extracellular regulated protein kinases 2, p38 mitogen-activated protein kinase and nuclear factor-κ-gene binding p65 in synovial tissue of RA group were significantly increased when compared with control group, which were lower remarkably in moxa group than those in RA group. The apoptosis rates of macrophages in RA group were significantly down-regulated as compared with the control group, which were up-regulated in moxa group compared with the RA group. The levels of IL-2 in synovial fluid from the RA group were elevated significantly as compared with that from control group, but those of the moxa group were reduced when compared with those from RA group. CONCLUSIONS: Moxibustion may simultaneously regulate the expressions of MIF and its related signaling pathways molecules, the apoptosis rate of macrophages in synovial tissue, as well as the level of inflammatory factors in synovial fluid. The results suggest that the anti-inflammatory effect of moxibustion on RA may be related to inhibit the expression of MIF in synovial tissue, the molecules of some related signaling pathways and promote the apoptosis of macrophage.

Objective:To observe the expression of serum nuclear factor-κB (NF-κB) and monocyte chemotactic protein-1 (MCP-1) in patients with early diabetic nephropathy (EDN) and the effect of pioglitazone on the expression of inflammatory factors and renal protective mechanism.Methods:A retrospective case-control study was conducted.From January 2019 to December 2019, the patients were divided into pioglitazone group ( n=35) and glimepiride group ( n=34). At the same time, 30 healthy people in the physical examination center of our hospital were selected as the control group.The levels of serum NF-κB and MCP-1 were detected by immunohistochemistry.The changes of fasting glucose, Hemoglobin A1C (HbA1c), renal function, urinary albumin excretion rate (UAER), and hypersensitive C-reactive protein(hsCRP), interleukin-6(IL-6), homeostasis model insulin Resistance index (HOMA-IR) were detected and compared among the three groups before treatment, pioglitazone group and glimepiride treatment group after treatment.To observe the effect of pioglitazone on serum NF-kB and MCP-1 expression in patients with early type 2 diabetic nephropathy. Results:Serum NF-κB, MCP-1, UAER, fasting blood glucose, HbA1c, HOMA-IR, hsCRP, IL-6 were significantly higher in the diabetic nephropathy group than those in the control group before treatment ( t values were 9.16, 7.61, 16.99, 17.01, 17.05, 12.01, 8.69, 6.28, all P<0.01). After 12 weeks of treatment, the levels of NF- κB, MCP-1, HOMA-IR, hsCRP, IL-6 and UAER in pioglitazone group were lower than those in glimepiide group ( t values were -5.03, -4.63, -2.35, -8.03, -3.06, -2.10, P<0.05 or P<0.01). After treatment, there were no statistically significant differences in fasting blood glucose and HbA1c between the pioglitazone group and the glimepiide group (all P>0.05). Serum NF-κB, MCP-1, HbA1c, HOMA-IR and UAER in EDN group were significantly positively correlated ( R values were 0.568, 0.532, 0.521, 0.466, all P<0.05). Conclusion:The expression of NF - κ B and MCP-1 in serum of EDN patients was increased, which indicated that there was chronic inflammation in patients.Pioglitazone could down regulate the expression of NF - κ B and MCP-1, so as to play an anti-inflammatory and renal protective role.
