ObjectiveBased on the experience of traditional quality evaluation， the quality of Atractylodis Macrocephalae Rhizoma（AMR） with different production methods such as direct seeding， transplanting after seedling raising， topping and non-topping， and difference in growth years was compared. MethodVernier caliper was used to measure the trait data of AMR in different production methods. Paraffin sections of AMR with different production methods were made by saffron solid green staining， and the microstructure was observed. The contents of water-soluble and alcohol-soluble extracts in AMR with different production methods were determined according to the 2020 edition of Chinese Pharmacopoeia. The content of water-soluble total polysaccharides in AMR with different production methods was detected by sulfuric acid-anthrone method. Fiber analyzer was used to detect the content of fiber components in AMR with different production methods. The contents of monosaccharides， oligosaccharides and some secondary metabolites in AMR with different production methods were detected by ultra performance liquid chromatography（UPLC）， and the differences of chemical components were compared by multivariate statistical analysis methods such as principal component analysis（PCA） and partial least squares-discriminant analysis（PLS-DA）. ResultIn terms of traits， the 3-year-old AMR with direct seeding and without topping was close to the high-quality AMR with "phoenix-head and crane-neck， strong sweetness and clear aroma" recorded in ancient materia medica， followed by the 3-year-old AMR with topping after transplanting， while the 2-year-old AMR with topping after transplanting with high market circulation rate was generally fat and strong with mild odor. In the microscopic aspect， the arrangement of xylem vessels and fiber bundles in the 3-year-old samples formed two obvious rings. Compared with the 2-year-old samples cultivated in Bozhou and Zhejiang， the 3-year-old samples without topping after transplanting had more wood fibers. In terms of chemical composition， the contents of 70% ethanol extract， fructose， glucose， sucrose， 1-kestose， atractylenolide Ⅰ， chlorogenic acid， neochlorogenic acid， cryptochlorogenic acid and other components in 3-year-old AMR with direct seeding and without topping were significantly higher than those in the other three samples（P<0.05）. The contents of cellulose， 70% ethanol extract， sucrose， atractylenolide Ⅰ， atractylone and other components in 3-year-old AMR with topping after transplanting were significantly higher than those in the 2-year-old AMR with high market circulation rate（P<0.05）， while the contents of water-soluble extract and water-soluble total polysaccharides in 2-year-old samples with topping after transplanting were significantly higher than those in the 3-year-old AMR with topping after transplanting， direct seeding and without topping（P<0.05）. ConclusionUnder the current mainstream production mode， too much manual intervention makes AMR heavily enriched in polysaccharides and increased the yield， but the accumulation of sweet substances， fragrant substances and fiber substances is insufficient， which affects its quality. The current quality standard of AMR has some shortcomings in guiding the high quality production of it， it is suggested to revise the quality standard of AMR， supplement the quantitative analysis of secondary metabolites， and strengthen the production of imitation wild AMR.

Objective To investigate the effect and mechanism of methyltransferase-like 3(METTL3)on the pro-liferation,migration,and secretion of inflammatory factors by synovial fibroblasts from rheumatoid arthritis(RA).Methods The expression of METTL3 in synovial tissue(SF)from 25 patients with rheumatoid arthritis and 25 pa-tients with osteoarthritis was detected by RT-qPCR and immunohistochemistry,respectively.The concentration of RNA m6A was detected by ELISA.RA synovial fibroblasts were isolated and cultured,and divided into NC(nor-mal control)group,hi-METTL3(overexpression of METTL3)group,si-METTL3(knock-down METTL3)group,and STM2457(METTL3 specific inhibitor)intervention group.Cell proliferation was detected by CCK-8 method.Apoptosis was detected by flow cytometry.And the concentrations of interleukin-6(IL-6),interleukin-17A(IL-17A),receptor activator of nuclear factor-kappa B ligand(RANKL),and osteoprotegerin(OPG)in the superna-tant of cell culture were detected by ELISA.Results Compared with synovial tissue of osteoarthritis,the expres-sion of mRNA m6A and METTL3 in synovial tissue of RA significantly increased(P<0.05).After overexpression of METTL3,the expression of m6A in synovial fibroblasts increased.The proliferation and migration abilities of SF in hi-METTL3 group were significantly improved,and their apoptosis did not change significantly.The secretion of cytokines IL-6 and RANKL of SF in hi-METTL3 group significantly increased,while the OPG significantly de-creased(P<0.05).After interfering with METTL3 expression,the expression of m6A in synovial fibroblasts de-creased.Cell proliferation and migration of SF in siMETTL3 group significantly decreased.The secretion of cyto-kines IL-6 and RANKL significantly decreased,and OPG significantly increased(P<0.05).After intervention with METTL3 inhibitor STM2457,the proliferation and migration of synovial fibroblasts were significantly reduced,and the secretion of cytokines IL-6 and RANKL significantly reduced,and OPG significantly increased(P<0.05).There was no significant difference in the expression of IL-17A among each group.Conclusion METTL3 may promote the proliferation and migration of RA synovial fibroblasts,enhance the expression of IL-6 and RANKL,and inhibit the expression of OPG through RNA m6A methylation modification.

【Objective】 To explore the effect and mechanism of Fasudil in the treatment of experimental autoimmune myocarditis (EAM) in mice so as to provide a theoretical basis for the clinical use of Fasudil in treating myocarditis. 【Methods】 Balb/c male mice were used as the research objects, and the EAM mice model was constructed using MyHC-α614-629 polypeptide. Mononuclear cells were isolated and cultured to detect the number of mononuclear cells in mouse spleen. Inflammation infiltration, fibrosis and IL-6 expression in mouse myocardial tissue were detected by HE staining, Masson staining and immunohistochemistry, respectively. The protein expressions of Notch1 and IL-6 were detected by Western blotting. qRT-PCR was used to detect the expressions of pro-inflammatory factors (IL-1α, IL-1β and IL-6) as well as key genes of TLRs and NOTCH signaling pathway. 【Results】 EAM mice showed increased HW, decreased BW, increased HW/e-BW, and increased inflammatory infiltration and fibrosis in myocardial tissue. The above-mentioned symptoms or pathological features were improved in EAM mice treated with Fasudil. The analysis showed that the pro-inflammatory factors IL-1α, IL-1β and IL-6 in the myocardial tissue of EAM mice were significantly increased, but only the expression of IL-6 was statistically different after Fasudil treatment compared with the control group. In addition, TLRs signaling pathway might also play an important role in the EAM mice treated with Fasudil. The expressions of IL-6 and Notch1 were consistent, and the expressions of the key genes of NOTCH signaling pathway (Notch1, Hes1 and Jag2) were down-regulated after Fasudil treatment. 【Conclusion】 Fasudil exerts a protective effect on down-regulation of IL-6 expression by inhibiting the NOTCH signaling pathway in EAM mice.
