ObjectiveTo investigate the effect of quercetin on acute gouty arthritis (GA) in rats by inhibiting the reactive oxygen species (ROS)/NOD-like receptor protein 3 (NLRP3)/interleukin-1β (IL-1β) signaling pathway. MethodsSixty SPF-grade male SD rats were randomized into normal, model, colchicine (0.3 mg·kg-1), and low-, medium-, and high-dose (25, 50, 100 mg·kg-1, respectively) quercetin groups (n=10). The rats in the dosing groups were administrated with the corresponding drugs (10 mL·kg-1) by gavage once a day for one week. An equal volume of normal saline was given by gavage to rats in normal and model groups. One hour after drug administration on day 5, an acute GA model was established in other groups except the control group via intra-articular injection of monosodium urate (MSU) suspension into the right posterior ankle joint cavity. The joint swelling and gait were scored at the time points of 6, 12, 24, 48 h after modeling. Histopathological alterations in the ankle joint tissue from each group were assessed by hematoxylin-eosin (HE) staining. Malondialdehyde (MDA), xanthine oxidase (XOD), and total superoxide dismutase (T-SOD) assay kits were used to assess the levels of MDA, XOD, and T-SOD in the serum. The levels of tumor interleukin-6 (IL-6), necrosis factor-α (TNF-α), and IL-1β in the rat serum, as well as ROS in the ankle joint tissue, were measured by enzyme-linked immunosorbent assay (ELISA). Western blot was performed to determine the protein levels of NLRP3, thioredoxin-interacting protein (TXNIP), apoptosis-associated speck-like protein containing a CARD domain (ASC), precursor cysteinyl aspartate-specific proteinase-1 (pro-Caspase-1), cleaved Caspase-1 (Caspase-1 p20), and IL-1β in the ankle joint tissue. Real-time PCR was employed to assess the mRNA levels of TXNIP, NLRP3, ASC, IL-1β, and TNF-α in the ankle joint tissue. ResultsCompared with the normal group, the model group exhibited decreased spontaneous activity, mental fatigue, increased ankle joint swelling and gait scores (P<0.01), aggravated synovial tissue edema and inflammatory cell infiltration (P<0.01), elevated levels of XOD, MDA, TNF-α, IL-1β, and IL-6 in the serum and ROS in the joint tissue (P<0.01), a declined level of T-SOD (P<0.01), up-regulated protein levels of NLRP3, TXNIP, ASC, pro-Caspase-1, Caspase-1 p20, and IL-1β in the ankle joint tissue (P<0.01), and up-regulated mRNA levels of NLRP3, TXNIP, ASC, IL-1β, and TNF-α in the ankle joint tissue (P<0.01). Compared with the model group, the medium- and high-dose quercetin groups showed improved general conditions, decreased gait scores (P<0.05, P<0.01), reduced joint swelling (P<0.01), alleviated synovial tissue edema and inflammatory cell infiltration (P<0.05, P<0.01), lowered levels of XOD, MDA, TNF-α, IL-1β, and IL-6 in the serum and ROS in the joint tissue (P<0.01), increased levels of T-SOD (P<0.01), down-regulated protein levels of TXNIP, NLRP3, ASC, pro-Caspase-1, Caspase-1 p20, and IL-1β in the ankle joint tissue (P<0.05, P<0.01), and down-regulated mRNA levels of TXNIP, NLRP3, ASC, IL-1β, and TNF-α in the ankle joint tissue (P<0.01). Low-dose quercetin also ameliorated some of the above parameters (P<0.05, P<0.01). ConclusionQuercetin exerts anti-GA effects by blocking the ROS/NLRP3/IL-1β signaling pathway, downregulating NLRP3 inflammasome activation, and inhibiting the production of pro-inflammatory cytokines including TNF-α, IL-1β, and IL-6.

ObjectiveTo characterize the quality differences among different germplasm and introduced varieties of Bupleurum scorzonerifolium roots(BSR), and explore the underlying molecular mechanisms, providing a basis for high-quality production and quality control. MethodsWild BSR from Yulin(YLW) served as the quality reference, we conducted comparative analysis among YLW, locally domesticated wild germplasm in Yulin(YLC3), Daqing germplasm introduced and cultivated in Yulin(YLDQC3), and locally cultivated germplasm in Daqing(DQC3). A combination of traditional pharmacognostic methods and modern multi-omics analyses was employed, including macroscopic traits(appearance, odor), microscopic features(proportions of cork, phloem, xylem), cell wall component contents(hemicellulose, cellulose, lignin), carbohydrate contents(starch, water-soluble polysaccharides), marker compound contents(ethanol-soluble extracts, total saponins, liposoluble extracts, and saikosaponins A, B2, C, D), metabolomics, and transcriptomics, in order to systematically characterize quality differences and investigate molecular mechanisms among these samples. ResultsMacroscopically, Yulin-produced BSR(YLW, YLC3, YLDQC3) exhibited significantly greater weight, length, and upper and middle diameters than Daqing-produced BSR(DQC3). Odor-wise, YLW and YLC3 had a a fragrance taste, YLDQC3 had a rancid oil odor, and DQC3 had a sweet and fragrant taste. Microscopically, Yulin germplasm(YLW, YLC3) and Daqing germplasm(YLDQC3, DQC3) shared similar structural features, respectively. However, Yulin germplasm showed significantly higher proportions of cork and phloem, as well as stronger xylem vessel staining intensity compared to Daqing germplasm. Regarding various component contents, Yulin germplasm contained significantly higher levels of ethanol-soluble extracts, total saponins, and saikosaponins A, B2, C, D, while Daqing germplasm had significantly higher levels of hemicellulose, starch, and liposoluble extracts. After introduction to Yulin, the Daqing germplasm(YLDQC3) showed increased starch, water-soluble polysaccharides and liposoluble extracts contents, decreased cell wall component content, but no significant difference in other component contents. Metabolomics revealed that saponins and terpenes accumulated significantly in Yulin germplasm, while alcohols and aldehydes accumulated predominantly in Daqing germplasm. Transcriptomics indicated similar gene expression patterns within the same germplasm but specificity between different germplasms. Integrative metabolomic-transcriptomic analysis identified 145 potential key genes associated with the saikosaponin biosynthesis pathway, including one acetyl-coenzyme A(CoA) acetyltransferase gene(ACAT), one 3-hydroxy-3-methylglutaryl-coenzyme A synthase gene(HMGS), two hydroxymethylglutaryl-CoA(HMG-CoA) reductase genes(HMG), one phosphomevalonate kinase gene(PMK), one 1-deoxy-D-xylose-5-phosphate synthase gene(CLA), one hydroxymethylbuten-1-aldol synthase gene(HDR), two farnesyl pyrophosphate synthase genes(FPPS), one squalene synthase gene(SQS), one β-amyrin synthase gene(BAS), 102 cytochrome P450(CYP450) gene family members, and 32 uridine diphosphate-glucuronosyltransferase(UGT) gene family members. ConclusionAmong the three cultivated types, YLC3 most closely resembles YLW in appearance, microscopic features, contents of major bioactive constituents, metabolomic and transcriptomic profiles. Yulin germplasm exhibits superior saponin synthesis capability compared to Daqing germplasm, and Yulin region is more suitable for the growth of B. scorzonerifolium. Based on these findings, it is recommended that artificial cultivation in northern Shaanxi and similar regions utilize the local Yulin germplasm source cultivated for at least three years.

ObjectiveTo compare the differences between wild Alpiniae Oxyphyllae Fructus(WAOF) and cultivated Alpiniae Oxyphyllae Fructus(CAOF) through a traditional quality evaluation system for medicinal materials. MethodsA total of 10 batches of WAOF and 12 batches of CAOF samples were collected from various regions of Hainan province. Relevant analytical methods from the 2020 edition of the Pharmacopoeia of the People's Republic of China were employed to observe the characteristics of WAOF and CAOF, followed by microscopic identification, thin-layer chromatography(TLC) identification, moisture content(toluene method), total ash, acid-insoluble ash, water-soluble and alcohol-soluble extracts(hot dipping method), water-soluble protein, total polysaccharides and total flavonoids(ultraviolet spectrophotometry), and volatile oil content(method A under general rule 2204). The contents of five active components(protocatechuic acid, chrysin, kaempferol, tectochrysin and nootkatone) were quantified using ultra-performance liquid chromatography(UPLC), and the antioxidant activity was evaluated. Building upon traditional quality evaluation of AOF, quantitative measurements were conducted on its appearance traits including diameter, length, plumpness(diameter/length ratio), and color. Canonical correlation analysis was performed using SPSS 26.0 to explore relationships between appearance traits and intrinsic quality. ResultsNo significant differences were observed between WAOF and CAOF in microscopic observation, TLC identification, moisture content, protocatechuic acid content, kaempferol content, odor, or antioxidant activity measured by 2,2ʹ-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid)(ABTS) method. WAOF exhibited significantly higher levels in water-soluble extracts, alcohol-soluble extracts, total polysaccharide content, water-soluble protein content, 100-grain weight, length, and total color difference(ΔE*ab) compared to CAOF(P<0.01). In contrast, CAOF showed significantly higher levels of total ash, acid-insoluble ash, content of total flavonoids, volatile oil content, chrysin content, tectochrysin content, nootkatone content, diameter, plumpness, lightness(L*), red-green chromaticity(a*), yellow-blue chromaticity(b*), and antioxidant activity measured by 1,1-diphenyl-2-picrylhydrazyl(DPPH) method compared to WAOF(P<0.01). Correlation analysis between 7 phenotypic traits and 8 quality traits revealed that among the phenotypic traits, plumpness, L*, a*, and b* exerted significant influence on intrinsic quality. Among the quality traits, total flavonoids, volatile oils, nootkatone, chrysin, and tectochrysin contributed substantially to intrinsic quality. ConclusionPlumpness, L*, a*, and b* of AOF significantly influence its intrinsic quality, and higher values of these parameters indicate relatively superior intrinsic quality. The comprehensive quality evaluation reveals that CAOF samples collected in this study are superior to their wild counterparts.

Metabolic reprogramming, as one of the core hallmarks of malignant tumors, plays a key role in the occurrence, development and treatment of breast cancer (BC). Abnormal changes in glucose metabolism, amino acid metabolism, lipid metabolism, as well as the tricarboxylic acid (TCA) cycle and oxidative phosphorylation (OXPHOS) pathways significantly influence the pathogenesis and progression of BC. Studies have shown that various active components of traditional Chinese medicine (TCM) (such as berberine, matrine, quercetin, curcumin, etc.) and their compound formulations (e.g. Xihuang pill, Danzhi xiaoyao powder, Yanghe decoction, etc.) can inhibit the proliferation and migration of BC cells and induce apoptosis by regulating key metabolic pathways such as glycolysis, lipid synthesis, and amino acid metabolism. TCM demonstrates multi-target and holistic regulatory advantages in intervening in BC metabolic reprogramming, showing significant potential in modulating key molecules like hypoxia inducible factor-1α, hexokinase-2, pyruvate kinase M2, lactate dehydrogenase A, glucose transporter-1, fatty acid synthase, and signaling pathways such as AKT/mTOR. However, current researches still focus predominantly on glucose metabolism, with insufficient mechanistic studies on lipid metabolism, amino acid metabolism, the TCA cycle, and OXPHOS. The precise targets, molecular mechanisms, and clinical translation value of these interventions require further validation and clarification through more high-quality experimental studies and clinical trials.

Metabolic associated fatty liver disease (MAFLD) is the main type of chronic liver disease in the world, with an increasingly higher incidence rate and a younger age of onset. At present, the treatment of MAFLD mainly depends on lifestyle intervention and comorbidity management, and there is still a lack of effective drugs for MAFLD itself. As a classic nonsteroidal anti-inflammatory drug of the salicylic acid family, aspirin can intervene in the pathological process of MAFLD by regulating lipid metabolism, relieving insulin resistance, reducing liver inflammation and oxidative stress response, exerting an anti-liver fibrosis effect, and inhibiting hepatocellular carcinoma, and therefore, it has the value of preventing disease onset, delaying disease progression, and reversing disease condition. This article systematically reviews the mechanism of action and safety of aspirin in the treatment of MAFLD, in order to provide more drug treatment options for MAFLD patients.

Community-acquired pneumonia (CAP) refers to an infectious inflammation of the lung parenchyma (including the alveolar wall,that is,the broad pulmonary interstitium) acquired outside the hospital. Its common pathogens include streptococcus pneumoniae,respiratory viruses, mycoplasma pneumoniae, and so on. The related factors for the occurrence and development of CAP include patient characteristics (immune function,mucus production and clearance function,coagulation function,physical condition, and comorbidity) and pathogen characteristics (susceptibility,virulence,and antibiotic resistance). The pathogenesis of CAP lies in immune deficiency,pathogen invasion,inflammatory response disorder,mucus production and clearance disorder, coagulation disorder, and so on. The pathogenesis of CAP in traditional Chinese medicine can be described as "vital Qi deficiency and toxic stasis". Vital Qi deficiency (lack of immunity) is the potential pathogenesis of the disease and easy to be invaded by external pathogens (respiratory pathogens). Toxic stasis (inflammatory disorder,mucus production and clearance disorder,and coagulation dysfunction) is the key pathogenic factor. Vital Qi deficiency and toxic stasis are intermingled in a state of deficiency and excess,which suggests that the treatment of CAP lies in strengthening vital Qi and eliminating pathogenic factors. This involves strengthening vital Qi in the whole process to consolidate body resistance and nourish promordial Qi. It also involves clearing heat,eliminating phlegm,removing dampness,and dispelling stasis to dispel pathogenic toxins based on the syndrome differentiation. Its action mechanism is to regulate immune and inflammatory responses,resist pathogens,and improve mucus production and clearance, as well as coagulation disorders. Starting from the key pathogenesis of CAP,"vital Qi deficiency and toxic stasis", this paper discussed the pathogenesis of CAP and summarized the action mechanism of vital Qi strengthening for detoxification in its treatment. It is intended to complement the theoretical system by identifying "vital Qi deficiency and toxic stasis" as the key pathogenesis underlying CAP and the scientific connotation of treating CAP with vital Qi strengthening for detoxification,thereby providing insights for its clinical application.

ObjectiveTo systematically evaluate the methodological quality and measurement properties of traditional Chinese medicine (TCM) syndrome efficacy evaluation scales, and to provide evidence-based references for selecting high-quality assessment tools in TCM clinical practice. MethodsChina National Knowledge Infrastructure (CNKI), Wanfang Data, VIP Database, Chinese Biomedical Literature Database (CBM), PubMed, the Cochrane Library, Embase, and Web of Science were searched from inception to April 2, 2025, for studies evaluating the measurement properties of TCM syndrome efficacy evaluation scales. Data were extracted, and the methodological quality and measurement properties of the included scales were assessed according to the consensus-based standards for the selection of health measurement instruments (COSMIN). Recommendation levels were formulated based on the grading of evidence. ResultsA total of 46 studies were included, involving 22 generic syndrome efficacy evaluation scales and 24 disease-specific syndrome efficacy evaluation scales. None of the scales reported cross-cultural validity or measurement error. According to the recommendation grades, 2 scales met Grade A recommendations and are suggested for clinical use; 38 scales were classified as Grade B, indicating potential applicability but requiring further validation; and 6 scales were classified as Grade C, suggesting the need for further refinement. ConclusionExisting TCM syndrome efficacy evaluation scales exhibit substantial variability in methodological quality, incomplete reporting of measurement properties, and insufficient attention to scale revision. Future efforts should emphasize standardized design in the development of TCM syndrome scales, strengthen validation procedures for key measurement properties, and prioritize dynamic revision of scales, thereby providing high-quality tools to support the precise evaluation of syndrome efficacy.

AIM: To investigate variation patterns of corneal biomechanical parameters and binocular symmetry among children of different genders aged 8-16 years.METHODS:A retrospective study was conducted, and children who underwent optometric examinations at the ophthalmology department of our hospital were enrolled between January 2022 and December 2024. Measurements included the flat keratometry(K1), steep keratometry(K2), and mean curvature(Km)of the anterior corneal surface, horizontal visible iris diameter(HVID), central corneal thickness(CCT), corneal endothelial cell density(CECD), average cell size(ACS), coefficient of variation(CV), and hexagonality(HEX). Corneal parameters and binocular differences were compared between genders and across age groups.RESULTS:A total of 621 children(1 242 eyes)were enrolled in this study, including 284 males(568 eyes), 337 females(674 eyes), 528 children aged 8-12 years(1 056 eyes), and 93 children aged 13-16 years(186 eyes). In children aged 8-16 years, the K1, K2, Km and CV of both eyes, as well as the interocular CCT differences in boys were significantly lower than those in girls(all P<0.05), while the HVID and HEX of both eyes, as well as the CCT of the left eye in boys were significantly higher than those in girls(all P<0.05). Children aged 8-12 years had significantly higher K1, Km, CECD and HEX in both eyes, and significantly lower ACS in both eyes than those aged 13-16 years(all P<0.05). K1, K2, Km, CECD and HEX in both eyes were negatively correlated with age(P<0.05); ACS in both eyes was positively correlated with age(P<0.001); K1 and Km of the right eye were positively correlated with the CECD of the right eye(P<0.05), and K1 and CCT of the left eye were positively correlated with the CECD of the left eye(P<0.05).CONCLUSION:Significant gender differences exist in corneal parameters among children aged 8 to 16 years, while binocular symmetry remained stable.

ObjectiveTo explore the relationship between negative life events and depression severity in adolescent patients with depressive disorder, as well as the chain mediating role of insomnia symptoms and quality of life. Methods374 outpatient patients and hospitalized patients with adolescent depressive disorders were enrolled. The Adolescent Life Event Scale (ASLEC), the Insomnia Severity Index (ISI), the World Health Organization Quality of Life Questionnaire Short Form (WHOQOL-BREF), and the Center for Epidemiology Depression Scale (CES-D) were used to evaluate the negative life event situation, insomnia symptoms, quality of life level and depression severity of the subjects, respectively. In addition, the PROCESS 4.0 macroprogram was used to analyze the chain mediating effect of insomnia symptoms and quality of life between negative life events and depression severity in patients with adolescent depressive disorder. ResultsThe results of correlation analysis showed that there was a significant correlation between negative life events and insomnia symptoms, quality of life, and depression severity (all P<0.05). In addition, the results of chain mediation showed that negative life events had a significant direct effect on depression severity, with an effect size of 0.12 (P<0.001). Insomnia symptoms and quality of life played a mediating role in the relationship between negative life events and depression severity in patients with adolescent depressive disorders, with indirect effect sizes of 0.062 (95%CI: 0.040-0.087) and 0.091 (95%CI: 0.059-0.123), respectively. It could also play a chain mediation role, and the effect size was 0.039 (95%CI: 0.024-0.057). ConclusionNegative life events experienced by patients with adolescent depressive disorder not only directly affect the severity of depressive symptoms, but may also indirectly exacerbate depression through insomnia symptoms and quality of life.
