Objective To investigate the correlation between serum microRNA(miR)-410,miR-17-5p,and miR-21 expression levels with disease activity in patients with psoriasis vulgaris.Methods A total of 126 pa-tients with psoriasis vulgaris who visited Department of Dermatology in the hospital from January 2022 to January 2024 were included as the research group(51 cases in the active phase,37 cases in the quiescent phase,and 38 cases in the degenerative phase).According to the Psoriasis Area and Severity Index(PASI)scoring method,the patients were assigned into 52 cases of mild piasis group and 74 cases of moderate to se-vere sis group.126 healthy individuals who underwent physical examinations at the hospital were included as the control group.Fluorescence quantitative PCR was applied to detect the expression levels of miR-410,miR-17-5p,and miR-21.The general clinical data of the research group and the control group were compared.The expression levels of serum miR-410,miR-17-5p,and miR-21 were compared among different groups.Spearman method was applied to analyze the correlation between serum miR-410,miR-17-5p,miR-21 and disease activity(PASI score)in patients with psoriasis vulgaris.Receiver operating characteristic curve was applied to analyze the diagnostic value of serum miR-410,miR-17-5p,and miR-21 for disease activity in patients with psoriasis vulgaris.Results Compared with the control group,the serum miR-410 expression level in the research group was lower,while the serum miR-17-5p and miR-21 expression levels were higher(P＜0.05).The serum miR-410 expression level of patients with psoriasis vulgaris in different periods showed a decreasing trend and ser-um miR-17-5p and miR-21 expression levels showed increasing trends compared with the control group(P＜0.05).The serum miR-410 expression level in the moderate to severe group was lower than that in the mild group,while the serum miR-17-5p and miR-21 expression levels were higher than those in the mild group(P＜0.05).Serum miR-410 was negatively correlated with PASI score in patients with psoriasis vulgaris,while serum miR-17-5p and miR-21 were positively correlated with PASI score(P＜0.05).The area under the curve of serum miR-410,miR-17-5p,miR-21,and their combined diagnosis for disease activity in patients with psoriasis vulgaris was 0.790,0.843,0.795,and 0.969,respectively.The combination of the three was superior to their individual diagnosis.Conclusion The occurrence and development of psoriasis vulgaris are related to the expression levels of serum miR-410,miR-17-5p and miR-21,and the changes in the expression levels of three could evaluate the severity of the disease in patients with psoriasis vulgaris.

ObjectiveTo explore the impact of exogenous chitosan on the growth and metabolism of Glycyrrhiza uralensis Fisch. (G. uralensis) and to improve the quality of cultivated G. uralensis for both medicine and food and aid in the increase in the content of effective components in G. uralensis.MethodsIn this study, whole G. uralensis plants were treated with exogenous chitosan, and comprehensive analyses of secondary metabolites and proteins were conducted using liquid chromatography with tandem mass spectrometry and isobaric tag for relative and absolute quantitation, respectively. Effects of chitosan induction on endogenous hormones of G. uralensis were analyzed using an enzyme-linked immunosorbent assay. Gene ontology function annotation and Kyoto Encyclopedia of Genes and Genomes pathway annotation were conducted to study the effect of chitosan induction on the proteome.ResultsChitosan induction significantly increased the levels of flavonoids in G. uralensis; however, the variation in triterpenoids was not substantial. Biological processes, including photosynthesis, secondary metabolism, and abiotic stress responses, were significantly enriched. Additionally, the photosynthetic pathway, photosynthesis-antenna protein pathway, and plant hormone signal transduction pathway were significantly enriched. In the flavonoid biosynthesis pathway, the upstream-related enzyme phenylalanine ammonia-lyase (PAL) and the downstream-related enzymes chalcone synthase (CHS), polyketide reductase (PKR), chalcone isomerase (CHI), and vestitone reductase (VR) were significantly upregulated.ConclusionsOur findings suggest that chitosan induction may promote the tricarboxylic acid (TCA) cycle, and the TCA cycle enhancement significantly upregulated PAL, CHS, PKR, CHI, and VR, the five key enzymes involved in flavonoid synthesis of G. uralensis, indicating that chitosan induction activated the entire metabolic pathway associated with flavonoids in G. uralensis. Our findings provide a reference for improving the quality of cultivated G. uralensis from the perspective of pharmacodynamic components.

OBJECTIVE To estimate the quality markers of antioxidant activity for standard decoction of Schisandrae Chinensis Fructus.METHODS 15 batches of Schisandrae Chinensis Fructus standard decoctions were subjected to quality evaluation by ultra high-performance liquid chromatography(UPLC)based on single-marker(QAMS)method,before being summarized by chemometrics analysis.The antioxidant abilities of 15 batches of samples were determined by DPPH and ABTS methods,while gray correlation analy-sis(GRA)and the partial least squares regression(PLSR)methods were subsequently applied to investigating the relationship between the contents of 8 components and the antioxidant activity.Ultimately,molecule docking was utilized to explore the binding properties between candidate quality markers and the core targets of anti-oxidation,with the experimental verification being executed on the indi-vidual compound by in vitro anti-oxidation.RESULTS There was no remarkable difference between the results of QAMS and external standard method(ESM),with P valued greater than 0.05.And it was speculated that protocatechuic acid,gomisin A,schizantherin B and schisandrin B were the constituents of quality difference.Moreover,the 4 quality variation components were reckoned to be the al-ternative markers on antioxidant according to the results of GRA and PLSR.The molecule docking result also showed that 4 candidate quality markers presented good binding affinity with the antioxidant core targets.The antioxidant capacity was presumably originated from the collaborated effects by multi-components in the standard decoction of Schisandrae Chinensis Fructus.In the interim,protocate-chuic acid exhibited noteworthy antioxidant efficacy with dosage-depended manner in the results of single-compound verification,which was best conformed to the characteristics of quality markers and supposed to be the antioxidant quality marker for Schisandrae Chinensis Fructus standard decoction.CONCLUSION This research predicts the potential antioxidant substances on the basis of content deter-mination by UPLC and in vitro antioxidant assay,but also provides rational foundation for quality assessment on other preparations of Schisandrae Chinensis Fructus.
