ABSTRACT Knowing the proliferative capacity of herbicide-resistant weeds is the basis for the integrated management. We collected seeds of two Echinochloa glabrescens Munro ex Hook. f. populations (TS and WH) from rice (Oryza sativa L.) fields in eastern China (F0 populations), and those from individuals surviving the initial metamifop treatment (F1 lines) were tested for their responses to metamifop, and common garden experiments were conducted to compare their productivities. We found that TS was highly resistant to metamifop, and WH was susceptible. After treated with metamifop at the label dose (120 g ai ha-1), averagely 56% and 16% of TS and WH F1 lines contained surviving seedlings, and averagely 24% and 1% F1 seedlings survived among total seedlings of the same population, respectively. After treated with metamifop at a dose of 0, 60, 120 or 240 g ai ha-1, surviving F0 plants escaped from higher doses reproduced higher proportions of metamifop-resistant F1 progenies in both populations. At 120 d after sowing (DAS), TS individuals surviving 2 × label dose of metamifop showed nonsignificant difference in plant heights, biomass and seed production, compared with relative control treatment; while WH plants surviving the label dose of metamifop decreased seed production by 25%-39%. One WH and TS plant individual surviving metamifop treatment at the label dose may generate 10-21 and 490-701 progenies resistant to the label dose of metamifop, respectively.

Abstract Objective: the purpose of this study was to assess the impact of 14 treatments including a total of 10 dietary antioxidants on the risk of prostate cancer. Material and methods: we searched PubMed, Embase, the Cochrane Library, and the Web of Science for only randomized controlled trials (RCTs) to investigate the effect of these 10 antioxidants on the risk of getting prostate cancer. Using the Cochrane Risk of Bias Assessment Tool, the methodological quality of the included studies was evaluated. Data extraction: studies were appraised by two investigators and data were extracted. Using a surface under cumulative ranking (SUCRA) probability, a Bayesian network meta-analysis was undertaken to evaluate the relative ranking of agents. Results: from the earliest accessible date through August 2022, RCTs were gathered. A total of 14 randomized controlled trials were included with a total sample size of 73,365 males. The results of the network meta-analysis showed that green tea catechins (GTCs) significantly reduced the risk of prostate cancer (SUCRA, 88.6 %) followed by vitamin D (SUCRA, 55.1 %), vitamin B6 (54.1 %), and folic acid was the lowest (22.0 %). Conclusion: based on the Ranking Plot of the Network, we can state that GTCs might have an impact on the prevention of prostate cancer compared to other dietary antioxidants, but we still need quality literature to further prove it.

Abstract Objective To explore whether Cyclic Adenosine Monophosphate (cAMP)-Epac1 signaling is activated in 1-Desamino-8-D-arginine-Vasopressin-induced Endolymphatic Hydrops (DDAVP-induced EH) and to provide new insight for further in-depth study of DDAVP-induced EH. Methods Eighteen healthy, red-eyed guinea pigs (36 ears) weighing 200-350 g were randomly divided into three groups: the control group, which received intraperitoneal injection of sterile saline (same volume as that in the other two groups) for 7 consecutive days; the DDAVP-7d group, which received intraperitoneal injection of 10 mg/mL/kg DDAVP for 7 consecutive days; and the DDAVP-14d group, which received intraperitoneal injection of 10 μg/mL/kg DDAVP for 14 consecutive days. After successful modeling, all animals were sacrificed, and cochlea tissues were collected to detect the mRNA and protein expression of the exchange protein directly activated by cAMP-1 and 2 (Epac1, Epac2), and Repressor Activator Protein-1 (Rap1) by Reverse Transcription (RT)-PCR and western blotting, respectively. Results Compared to the control group, the relative mRNA expression of Epac1, Epac2, Rap1A, and Rap1B in the cochlea tissue of the DDAVP-7d group was significantly higher (p< 0.05), while no significant difference in Rap1 GTPase activating protein (Rap1gap) mRNA expression was found between the two groups. The relative mRNA expression of Epac1, Rap1A, Rap1B, and Rap1gap in the cochlea tissue of the DDAVP-14d group was significantly higher than that of the control group (p< 0.05), while no significant difference in Epac2 mRNA expression was found between the DDAVP-14d and control groups. Comparison between the DDAVP-14d and DDAVP-7d groups showed that the DDAVP-14d group had significantly lower Epac2 and Rap1A (p< 0.05) and higher Rap1gap (p < 0.05) mRNA expression in the cochlea tissue than that of the DDAVP-7d group, while no significant differences in Epac1 and Rap1B mRNA expression were found between the two groups. Western blotting showed that Epac1 protein expression in the cochlea tissue was the highest in the DDAVP-14d group, followed by that in the DDAVP-7d group, and was the lowest in the control group, showing significant differences between groups (p< 0.05); Rap1 protein expression in the cochlea tissue was the highest in the DDAVP-7d group, followed by the DDAVP-14d group, and was the lowest in the control group, showing significant differences between groups (p< 0.05); no significant differences in Epac2 protein expression in the cochlea tissue were found among the three groups. Conclusion DDAVP upregulated Epac1 protein expression in the guinea pig cochlea, leading to activation of the inner ear cAMP-Epac1 signaling pathway. This may be an important mechanism by which DDAVP regulates endolymphatic metabolism to induce EH and affect inner ear function.

Abstract Background Alpha-kinase 1 (ALPK1) is a master regulator in inflammation and has been proved to promote renal fibrosis by promoting the production of IL-1β in diabetic nephropathy (DN) mice. Pyroptosis is involved in high glucose (HG)-induced tubular cells injury, characterized by activation of Gasdermin D (GSDMD) and the release of IL-1β and IL-18, resulting in inflammatory injury in DN. It is reasonable to assume that ALPK1 is involved in pyroptosis-related tubular injury in DN. However, the mechanism remains poorly defined. Methods Immunohistochemistry (IHC) staining was performed to detect the expression of pyroptosis- and fibrosis-related proteins in renal sections of DN patients and DN mice. DN models were induced through injection of streptozotocin combined with a high-fat diet. Protein levels of ALPK1, NF-κB, Caspase-1, GSDMD, IL-1β, IL-18 and α-SMA were detected by Western blot. HK-2 cells treated with high-glucose (HG) served as an in vitro model. ALPK1 small interfering RNA (siRNA) was transfected into HK-2 cells to down-regulate ALPK1. The pyroptosis rates were determined by flow cytometry. The concentrations of IL-1β and IL-18 were evaluated by ELISA kits. Immunofluorescence staining was used to observe translocation of NF-κB and GSDMD. Results The heat map of differentially expressed genes showed that ALPK1, Caspase-1 and GSDMD were upregulated in the DN group. The expression levels of ALPK1, Caspase-1, GSDMD and CD68 were increased in renal biopsy tissues of DN patients by IHC. ALPK1expression and CD68+ macrophages were positively correlated with tubular injury in DN patients. Western blot analysis showed increased expressions of ALPK1, phospho-NF-κB P65, GSDMD-NT, and IL-1β in renal tissues of DN mice and HK-2 cells, accompanied with increased renal fibrosis-related proteins (FN, α-SMA) and macrophages infiltration in interstitial areas. Inhibition of ALPK1 attenuated HG-induced upregulation expressions of NF-κB, pyroptosis-related proteins Caspase-1, GSDMD-NT, IL-1β, IL-18, α-SMA, and pyroptosis level in HK-2 cells. Also, the intensity and nuclear translocation of NF-κB and membranous translocation of GSDMD were ameliorated in HG-treated HK-2 cells after treatment with ALPK1 siRNA. Conclusions Our data suggest that ALPK1/NF-κB pathway initiated canonical caspase-1-GSDMD pyroptosis pathway, resulting in tubular injury and interstitial inflammation of DN.

Abstract Background Ischemia-reperfusion (IR) induces increased release of extracellular vesicles in the heart and exacerbates myocardial IR injury. We have previously shown that propofol attenuates hypoxia/reoxygenation (HR)-induced injury in human umbilical vein endothelial cells (HUVECs) and that microvesicles derived from propofol-treated HUVECs inhibit oxidative stress in endothelial cells. However, the role of microvesicles derived from propofol post-treated HUVECs ((HR + P)-EMVs) in IR-injured cardiomyocytes is unclear. In this study, we aimed to investigate the role of (HR + P)-EMVs in cardiac IR injury compared to microvesicles derived from hypoxic/reoxygenated HUVECs (HR-EMVs) and to elucidate the underlying mechanisms. Methods Hypoxia/reoxygenation (HR) models of HUVECs and AC16 cells and a mouse cardiac IR model were established. Microvesicles from HR-injured HUVECs, DMSO post-treated HUVECs and propofol post-treated HUVECs were extracted by ultra-high speed centrifugation, respectively. The above EMVs were co-cultured with HR-injured AC16 cells or injected intracardially into IR mice. Flow cytometry and immunofluorescence were used to determine the levels of oxidative stress and apoptosis in cardiomyocytes. Apoptosis related proteins were detected by Western blot. Echocardiography for cardiac function and Evans blue-TTC staining for myocardial infarct size. Expression of lncCCT4-2 in EMVs and AC16 cells was analysed by whole transcriptome sequencing of EMVs and RT-qPCR. The molecular mechanism of inhibition of myocardial injury by (HR + P)-EMVs was elucidated by lentiviral knockdown of lncCCT4-2, plasmid overexpression or knockdown of CCT4, and actinomycin D assay. Results In vitro and in vivo experiments confirmed that HR-EMVs exacerbated oxidative stress and apoptosis in IR-injured cardiomyocytes, leading to increased infarct size and worsened cardiac function. Notably, (HR + P)-EMVs induced significantly less oxidative stress and apoptosis in IR-injured cardiomyocytes compared to HR-EMVs. Mechanistically, RNA sequencing of EMVs and RT-qPCR showed that lncCCT4-2 was significantly upregulated in (HR + P)-EMVs and cardiomyocytes co-cultured with (HR + P)-EMVs. Reduction of lncCCT4-2 in (HR + P)-EMVs enhanced oxidative stress and apoptosis in IR-injured cardiomyocytes. Furthermore, the anti-apoptotic activity of lncCCT4-2 from (HR + P)-EMVs was achieved by increasing the stability of CCT4 mRNA and promoting the expression of CCT4 protein in cardiomyocytes. Conclusions Our study showed that (HR + P)-EMVs uptake by IR-injured cardiomyocytes upregulated lncCCT4-2 in cardiomyocytes and promoted CCT4 expression, thereby inhibiting HR-EMVs induced oxidative stress and apoptosis. Highlights Microvesicles from hypoxic/reoxygenated HUVECs (HR-EMVs) exacerbated oxidative stress and apoptosis in IR-injured cardiomyocytes. Microvesicles from propofol post-treated HUVECs ((HR + P)-EMVs) induced diminished oxidative stress and apoptosis in IR-injured cardiomyocytes compared with microvesicles from hypoxic/reoxygenated HUVECs (HR-EMVs). lncCCT4-2 was significantly highly expressed in (HR + P)-EMVs and cardiomyocytes co-cultured with (HR + P)-EMVs, and reduction of lncCCT4-2 in (HR + P)-EMVs enhanced oxidative stress and apoptosis in IR-injured cardiomyocytes. lncCCT4-2 inhibited HR-EMVs induced oxidative stress and apoptosis in HR-injured AC16 cells by increasing the stability of CCT4 mRNA and promoting the expression of CCT4 protein in AC16 cells.

BACKGROUND: Research and developmental (R) expenditure directly affects profits. Therefore, managers are likely to manipulate R expenditure to meet earnings thresholds. AIM: This study investigates whether managers manipulate R expenditure to meet earnings thresholds, while analysing whether the prospect theory explains this behaviour. SETTING: The setting is 62 South African firms listed on the Johannesburg Stock Exchange (JSE) studied from 2011 to 2019. METHOD: We collected 379 annual samples from the S Capital IQ database and applied the earnings distribution model to estimate the effect of the prospect theory on earnings management. RESULTS: Most South African listed enterprises have earnings above zero, or have avoided reporting earnings in decline before earnings manipulation. Furthermore, the study's findings reveal that enterprises that have earnings above zero, or have maintained their earnings in the previous period after manipulation, are risk lovers, whereas enterprises with earnings below zero, or lower than those in the previous period, are risk averters. CONCLUSION: South African listed enterprises do not have a tendency to manipulate R expenditures to achieve earnings above zero or avoid reporting declining earnings. The prospect theory also fails to explain their behaviour. CONTRIBUTION: This study is the first to analyse how the prospect theory explains the behaviour of earnings manipulation by using a sample of South African listed enterprises and thereby fills a research gap.

The current study aimed to assess the effects of the addition of dietary fermented feed (FF) on the growth performance, blood parameters, intestinal morphology, and number of cecal microorganisms of Sichuan white geese from 1 to 28 d of age. A total of 240, 1-day-old female geese were randomly divided into five groups with six replicates (eight birds per replicate). Geese in the control group were fed the basal diet (0.0% FF) and the experimental groups were fed the basal diet supplemented with 2.5%, 5.0%, 7.5%, and 10.0% FF, respectively. The 5.0% FF and 7.5% FF groups had greater body weights (BW), average daily feed intakes (ADFI), and average daily gains (ADG) than the control group. The feed/gain ratio (F/G) in the 7.5% FF group was higher than the control group. The concentrations of immunoglobulin A (IGA), superoxide dismutase (SOD), catalase, total antioxidant capacity (T-AOC), and glutathione peroxidase (GPx) in the 5.0% FF group were higher than those in the control group, whereas malondialdehyde (MDA) content in the 5.0% FF group was lower. Moreover, the FF did not affect the plasma biochemical indicators, number of cecal microorganisms, and intestinal morphology of geese in the groups. These findings indicate that 5.0% FF may improve the growth performance (BW, ADG, and ADFI), immunological function, and antioxidant capacity of Sichuan white geese from 1 to 28 days of age.

ABSTRACT This study investigated oxidative damage and exocrine dysfunction of fetal pancreas caused by maternal nutritional restriction. Eighteen ewes carrying singleton fetus were randomly divided into control group (CG, ad libitum, 0.67 MJ ME/BW0.75/d, n = 6), restricted group 1 (RG1, 0.33 MJ ME/BW0.75/d, n = 6), and restricted group 2 (RG2, 0.18 MJ ME/BW0.75/d, n = 6) at d 90 of pregnancy. Maternal undernutrition was imposed from d 90 to 140 of pregnancy. At 140 d of gestation, fetal blood and pancreas tissue were collected to determine fetal pancreatic extracellular matrix, antioxidant capacity, and indicators of exocrine dysfunction. With the decrease of maternal nutrition, the fetal body weight, pancreatic weight, and DNA content were reduced in RG2 compared with CG, and increased and thickened collagen fibers were observed in RG2. Fetuses in RG2 exhibited increased collagen 3 (COL3) and fibronectin (FN) levels relative to CG, and the COL1:COL3 ratio was lower than that of the CG. For RG1, we found increased COL3 compared with CG. Malondialdehyde, serum amylase, and serum lipase in fetal pancreas in RG2 increased, but the total antioxidant capacity (T-AOC) decreased compared with the CG. The impaired ovine fetal pancreas growth, antioxidant imbalance, and pancreatic exocrine dysfunction are induced by maternal undernutrition during late pregnancy.

ABSTRACT Purpose: Myocardial ischemia/reperfusion injury (MIRI) leads to myocardial tissue necrosis, which will increase the size of myocardial infarction. The study examined the protective effect and mechanism of the Guanxin Danshen formula (GXDSF) on MIRI in rats. Methods: MIRI model was performed in rats; rat H9C2 cardiomyocytes were hypoxia-reoxygenated to establish a cell injury model. Results: The GXDSF significantly reduced myocardial ischemia area, reduced myocardial structural injury, decreased the levels of interleukin (IL-1β, IL-6) in serum, decreased the activity of myocardial enzymes, increased the activity of superoxide dismutase (SOD), and reduced glutathione in rats with MIRI. The GXDSF can reduce the expression of nucleotide- binding oligomerization domain, leucine-rich repeat and pyrin domain containing nod-like receptor family protein 3 (NLRP3), IL-1β, caspase-1, and gasdermin D (GSDMD) in myocardial tissue cells. Salvianolic acid B and notoginsenoside R1 protected H9C2 cardiomyocytes from hypoxia and reoxygenation injury and reduced the levels of tumor necrosis factor α (TNF-α) and IL-6 in the cell supernatant, decreasing the NLRP3, IL-18, IL-1β, caspase-1, and GSDMD expression in H9C2 cardiomyocytes. GXDSF can reduce the myocardial infarction area and alleviate the damage to myocardial structure in rats with MIRI, which may be related to the regulation of the NLRP3. Conclusions: GXDSF reduces MIRI in rat myocardial infarction injury, improves structural damage in myocardial ischemia injury, and reduces myocardial tissue inflammation and oxidative stress by lowering inflammatory factors and controlling focal cell death signaling pathways.

Abstract Under the influence of the COVID-19, people's awareness of physical health and immunity has increased significantly. Chitooligosaccharide is an oligomer of β-(1, 4)-linked D -glucosamine, furthermore, is one of the most widely studied immunomodulators. Chitooligosaccharide can be prepared from the chitin or chitosan polymers through enzymatically, chemically or physically processes. Chitooligosaccharide and its derivatives have been proven to have a wide range of biological activities including intestinal flora regulation, immunostimulant, anti-tumor, anti-obesity and anti-oxidation effects. This review summarizes the latest research of the preparation methods, biological activities in immunity and safety profiles of Chitooligosaccharide and its derivatives. We recapped the effect mechanisms of Chitooligosaccharide basing on overall immunity. Comparing the effects of Chitooligosaccharide with different molecular weights and degree of aggregation, a reference range for usage has been provided. This may provide a support for the application of Chitooligosaccharide in immune supplements and food. In addition, future research directions are also discussed.

Abstract Bone morphogenetic protein 9 (BMP9) tends to be associated with various inflammatory responses of diseases, but its relationship with pulpitis remains unknown. Objective This study aimed to evaluate the effects and mechanisms of BMP9 in pulpitis. Methodology A rat model of pulpitis was used to evaluate the expression of BMP9, which was also analysed in Porphyromonas gingivalis lipopolysaccharide (Pg-LPS)-stimulated human dental pulp cells (hDPCs). The effects and mechanism of BMP9 on the regulation of inflammatory factors and matrix metalloproteinase-2 (MMP2) were evaluated using real-time quantitative PCR, western blotting, and immunocytofluorescence. Moreover, the migration ability of THP-1 monocyte-macrophages, treated with inflammatory supernate inhibited by BMP9, was previously tested by a transwell migration assay. Finally, a direct rat pulp capping model was used to evaluate in vivo the influence of the overexpression of BMP9 in pulpitis. Results The expression of BMP9 decreased after 24 h and increased after 3 and 7 d in rat pulpitis and inflammatory hDPCs. The overexpression of BMP9 inhibited the gene expression of inflammatory factors (IL-6, IL-8, and CCL2) and the secretion of IL-6 and MMP2 in Pg-LPS-stimulated hDPCs. The level of phosphorylated Smad1/5 was upregulated and the levels of phosphorylated ERK and JNK were downregulated. The inflammatory supernate of hDPCs inhibited by BMP9 reduced the migration of THP-1 cells. In rat pulp capping models, overexpressed BMP9 could partially restrain the development of dental pulp inflammation. Conclusion This is the first study to confirm that BMP9 is involved in the occurrence and development of pulpitis and can partially inhibit its severity in the early stage. These findings provided a theoretical reference for future studies on the mechanism of pulpitis and application of bioactive molecules in vital pulp therapy.

Abstract: The aim of this study was to investigate the effects of Idesia polycarpa fruit blackening on fruit and seed morphological characteristics, oil content, fatty acid content, seed germination rate and physiological properties. Germination tests were conducted under dry and wet storage at 5 °C for 0 d, 20 d, 40 d, 60 d and 80 d. The fruit mass, the 100-grain weight, the moisture content, the oil content of seeds and oleic acid in unsaturated fatty acids of black fruit are significantly lower than red fruit (P < 0.05). The germination rate of black fruit seeds was higher than red under wet storage and the malondialdehyde content of black fruits decreased with increasing storage time. Our results demonstrated that black fruits of I. polycarpa should not be discarded indiscriminately and that the color of the fruits can be chosen according to the purpose of use. Black fruits are picked for species propagation, while red fruits are mainly harvested for oil extraction.

Abstract In this study, we investigated the mechanical and energy-absorption properties of a star-shaped auxetic honeycomb under combined compression-shear loading. Novel fixtures were designed to conduct quasi-static combined compression-shear loadings. Experimental and numerical results show that the honeycomb undergoes an overall deformation based on cell rotation under quasi-static loading, producing an inclined deformation band. The normal yield stress decreased, and the shear yield stress increased with an increase in the loading angle. The extrusion deformation between meso-structures became more sufficient under dynamic combined loadings. The material deformation mode changed from overall deformation to local deformation accompanied by the formation of a shock wave. The yield criteria were established based on the ellipse equation. With an increase in the loading angle, the energy absorption in the normal and shear directions of the materials showed downward and upward trends, respectively. A theoretical model was proposed based on the 1D shock wave model to predict the energy-absorption behaviour under dynamic loading. study energyabsorption starshaped star shaped compressionshear compression quasistatic quasi static loadings band decreased angle mesostructures meso structures equation trends respectively D

Abstract Background Harlequin ichthyosis (HI) is a rare skin disorder with extremely high lethality due to a mutation of the ABCA12 gene. Because of its rarity and the often-late onset, prenatal screening for HI is extremely difficult, and most pregnant women might easily miss the period for optimal examinations. Objective To summarize the sonographic features of HI for prenatal diagnostic purposes. Methods The authors describe a case of HI with no family history who was diagnosed by using prenatal ultrasound scanning. The sonographic features of HI and the clinical characteristics of pregnant women were summarized by searching relevant literature over nearly two decades. Results The unique sonographic presentations including peeling skin, clenched hands and clubfeet, ectropion, flat nose, fetal growth impairment, polyhydramnios and echogenic amniotic fluid may be primarily related to skin disorders in HI fetuses. The authors also identified a novel pathogenic ABCA12 gene mutation and explained the possible pathogenic mechanisms. Study limitations Caution should be exercised in summarizing disease characteristics because of the small number of cases, and the authors are faced with the possibility of incomplete case searching. Conclusions HI has relatively unique sonographic features. Therefore, 2D-ultrasound combined with 3D-ultrasound may be an effective method for the prenatal diagnosis of HI. Moreover, a novel pathogenic ABCA12 gene mutation may provide important clues for future research on the etiology of HI. However, the authors consider that additional studies are needed to provide more evidence for prenatal diagnosis.

Métodos: los componentes activos y los objetivos de la cápsula Xiexin fueron seleccionados por la base de datos TCMSP. Se utilizaron las plataformas Genecards, OMIM, PharmGkb, TTD (Therapeutic Target Database) y Drugbank para buscar las dianas de la enfermedad en la dislipidemia. El diagrama reticular “componente-diana” fue construido por el software Cytoscape 3.7.0, y la interacción proteína-proteína (PPI) fue analizada por la plataforma STRING. Los análisis de enriquecimiento de Gene Ontology (GO) y Kyoto Encyclopedia of Genes and Genomics (KEGG) se realizaron mediante paquetes de datos en lenguaje R para predecir el mecanismo de acción. El software AutoDockVina y PyMol se utilizó para unir los componentes activos clave de la cápsula Xiexin y las proteínas clave de la PPI. Resultados: se seleccionaron 65 componentes activos y 114 dianas. Veintitrés compuestos activos clave fueron seleccionados a partir de la tabla “componentes farmacéuticos-dianas”. Las redes PPI incluyen principalmente proteínas básicas como PTGS2, PTGS1 y HSP90AA1. Los resultados del análisis de enriquecimiento de GO y KEGG en los objetivos comunes se refieren principalmente a la vía de señalización mediada por esteroides, la respuesta hormonal esteroidea, el transporte y metabolismo lipídicos, la regulación del almacenamiento de colesterol, la vía de la ciclooxigenasa y otras vías biológicas, así como la vía de señalización de PPAR, la vía de señalización de IL-17, la vía de señalización de PI3K-Akt, la vía de señalización de FcnnnnnnnnRI y otras vías relacionadas. La prueba de acoplamiento molecular mostró que la quercetina se une mejor a la proteína diana central HSP90AA1, que es la proteína diana con la mejor actividad de unión de los componentes químicos clave de la cápsula Xiexin. Conclusión: los principales componentes químicos de la cápsula Xiexin pueden participar en la regulación de la PPAR y otras vías de señalización mediante la regulación de genes clave como ESR1, MAPK14 (mitogen-activated protein kinase 14), HSP90AA1, por lo que pueden desempeñar un papel farmacológico en la intervención de la dislipidemia.

Abstract Objective: bioinformatic methods and molecular docking technology were used to predict the active components, targets, and related biological pathways of the Xiexin capsule in the intervention for dyslipidemia, exploring its mechanism. Methods: the active components and targets of the Xiexin capsule were screened by the TCMSP (Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform )database. Genecards (The Human Gene Database), OMIM (Online Mendelian Inheritance in Man), PharmGkb (Pharmacogenomics Knowledge Base database), TTD (Therapeutic Target Database), and Drugbank platforms were used to search the disease targets of dyslipidemia. The Cytoscape 3.8.0 software was used to construct the 'component-target' network diagram, and the STRING (functional protein association networks) platform was used to analyze protein-protein interaction (PPI). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomics (KEGG) enrichment analyses were performed by R language data packets to predict the mechanism of action. The AutoDockVina and PyMol software were used to dock the key active components in the Xiexin capsule and the core proteins in PPI. Results: a total of 66 effective components were screened, involving 114 targets; 87 key active compounds were screened from the 'drug-component-target' diagram. The PPI network mainly involved core proteins such as PTGS2 (prostaglandin-endoperoxide synthase 2), PTGS1 (prostaglandin-endoperoxide synthase 1), and HSP90AA1 (heat shock protein 90 alpha family class A member 1). GO and KEGG enrichment analysis results of common targets mainly involved hormone-mediated signaling pathway, steroid hormone response, lipid transport and metabolism, regulation of cholesterol storage, cyclooxygenase pathway, and other biological pathways, as well asMM PPAR (peroxisome proliferators-activated receptor) signaling pathway, IL-17 (interleukin 17) signaling pathway, PI3K-Akt (protein kinase b) signaling pathway, FcεRI signaling pathway, and other related pathways. Molecular docking verification showed that quercetin had the best binding with the core target protein HSP90AA1, and HSP90AA1 was the target protein with the best binding activity for the key chemical components in Xiexin capsules. Conclusion: the main chemical components in the Xiexin capsules may participate in the regulation of PPAR and other signaling pathways by regulating key genes such as ESR1 (estrogen receptor 1), MAPK14 (mitogen-activated protein kinase 14), and HSP90AA1, to exert the pharmacological effect of the intervention on dyslipidemia.
