Polycystic ovary syndrome （PCOS） is one of the most prevalent gynecological diseases， and its incidence is increasing year by year， seriously affecting the physical and mental health of female patients. The pathogenesis of this disease is complex and has not been fully clarified. At present， PCOS is mainly treated by Western medicine， which， however， has poor efficacy and induces various adverse reactions. Therefore， developing safe and effective therapies has become a difficult problem that needs to be solved. Studies have confirmed that traditional Chinese medicine （TCM） can regulate phosphatidylinositol 3-kinase/protein kinase B（PI3K/Akt）， mitogen-activated protein kinase/extracellular signal-regulated kinase （MAPK/ERK）， Toll-like receptor 4/nuclear factor-κB （TLR4/NF-κB）， transforming growth factor-β （TGF-β）/Smads， secreted glycoprotein/β-catenin （Wnt/β-catenin）， adenosine monophosphate-activated protein kinase （AMPK）， and advanced glycation endproduct/receptor for advanced glycation endproducts （AGE/RAGE） signaling pathways to ameliorate insulin resistance， inhibit inflammation and oxidative stress， regulate endocrine hormone disorders， and intervene in apoptosis and autophagy， thus alleviating the symptoms， slowing down the disease progression， and improving the ovarian function. The treatment of PCOS with TCM has demonstrated definite effects and high safety. Therefore， exploring this disease from cellular and molecular perspectives can provide a theoretical basis for its clinical treatment and new drug development. However， there is a lack of systematic reviews on the modulation of relevant signaling pathways by TCM in the treatment of PCOS. This article reviews the research progress in the treatment of PCOS with the active ingredients and compound prescriptions of TCM by regulating relevant signaling pathways in recent years， with the aim of providing evidence to support the promotion of TCM for treating PCOS in the future.

Objective: To investigate whether zerumbone ( ZER) has the effect of preventing cisplatin ( Cis) -induced acute kidney injury (Cis-AKI) . Methods: The MTT method was used to detect the effect of different concentrations of ZER on the cell viability of Cis-AKI. The in vivo and in vitro models of Cis-AKI mice were estab- lished by dividing into control group , separate administration group , model group , and dose group. Western blot and immunofluorescence experiments were used to detect the expression changes of kidney injury marker-1 ( KIM- 1) , phosphorylated NF-κB p65 ( P-p65 ) , Cleaved casepase3 , receptor interacting protein kinase 1 ( RIPK1) , RIPK3 , and tumor necrosis factor-α (TNF-α) . Real-time fluorescence quantitative PCR (qRT-PCR) was used to detect the mRNA expression of KIM-1 , TNF-α , interleukin-6 ( IL-6) , and monocyte chemoattractant protein-1(MCP-1) . Periodic acid-Schiff (PAS) staining confirmed the therapeutic effect of ZER on Cis-AKI. RNA-seq and cell thermal shift (CETSA) were used to explore possible target proteins. Results : MTT results showed that ZER could alleviate the decrease in cell viability of Cis-AKI ; in vivo and in vitro studies showed that compared with the model group , after treatment with ZER , its KIM-1 , P-p65 , Cleaved casepased3 , RIPK1 , RIPK3 , TNF -α expres- sion decreased significantly , and the mRNA expression of KIM-1 , TNF-α , IL-6 mRNA , and MCP-1 decreased. PAS staining showed that ZER had a therapeutic effect on Cis-AKI. RNA-seq and CETSA analysis showed that ZER might prevent and treat Cis-AKI by targeting the PIM1 protein. Conclusion ZER may alleviate Cis-AKI and im- prove inflammatory response and necroptosis by regulating PIM1 protein. ZER is expected to be a potential drug for the prevention and treatment of Cis-AKI.

OBJECTIVE: To assess the association of single nucleotide polymorphisms (SNPs) of interleukin-23 receptor (IL-23R) gene with susceptibility to psoriasis. METHODS: Two hundred and ten psoriasis patients admitted to Xinxiang Central Hospital from January 2019 to December 2024 were selected as the study group, and 210 healthy individuals undergoing physical examination during the same period were selected as the control group. 3 mL of peripheral venous blood sample was collected from each individual from the two groups, and PCR-Restriction fragment length polymorphism (PCR-RFLP) assay was used to determine the polymorphisms of the IL-23R gene at rs2201841, rs1004819, rs10889677, rs1343151 and rs1495965 loci. Genotypic and allelic distribution of each SNP locus was calculated to assess the association between SNPs of the IL-23R gene with the onset of psoriasis, and the difference in serum IL-23 levels among patients with different genotypes at each locus was compared. This study was approved by the Medical Ethics Committee of Xinxiang Central Hospital (Ethic No. 2024-749). RESULTS: The results showed that the frequency of CC genotype at rs1004819 locus of the study group was significantly higher than that of the control group (26.19% vs. 18.10%, P < 0.05), and the frequency of C allele was also significantly higher than that of the control group (54.05% vs. 42.62%, P < 0.05). There was no significant difference in allelic and genotypic frequencies between the two groups at rs2201841, rs10889677, rs1343151, and rs1495965 loci (P > 0.05). The dominant and recessive inheritance patterns at the rs1004819 locus are associated with susceptibility to psoriasis (P < 0.05), while the different inheritance patterns at rs2201841, rs10889677, rs1343151, and rs1495965 loci are not associated with psoriasis (P > 0.05). The serum IL-23 levels of patients with CC genotype at the rs1004819 locus were higher than those with the CT and TT genotypes (P < 0.05). No significant difference was detected in the serum levels of IL-23 between patients with different genotypes for the rs2201841, rs10889677, rs1343151, and rs1495965 loci (P > 0.05). CONCLUSION The polymorphism at the rs1004819 locus of the IL-23R gene is associated with susceptibility to psoriasis, and individuals carrying the CC genotype and C allele have a higher risk of developing the disease.

OBJECTIVE: To explore the clinical and genetic characteristics of a child with intellectual development disorder and seizures due to a variant of AP2M1 gene. METHODS: Clinical data of a child with intellectual development disorder and epilepsy who was admitted to the Department of Pediatric Neurology of the Third Affiliated Hospital of Zhengzhou University in January 2021 were retrospectively analyzed. Peripheral blood samples of the child and his parents were collected for whole exome sequencing. Candidate variant was verified by Sanger sequencing and pathogenicity analysis. The three-dimensional structure of the AP2M1 protein was visualized using Chimera v1.10.1 software. Pathogenicity of candidate variant was classified according to the Standards and Guidelines for the Interpretation of Sequence Variants from the American College of Medical Genetics and Genomics American College of Medical Genetics (ACMG). With "AP2M1 gene" "epilepsy" "intellectual disability" as the keywords, relevant cases were searched from CNKI, Wanfang Data knowledge service platform and PubMed databases with the search time spanning from the establishment of the database to September 2024. This study was approved by the Medical Ethics Committee of the Third Affiliated Hospital of Zhengzhou University (Ethics No.: 2020-57). RESULTS: The child was a 8-years-and-6-months-old boy, who could raise his head at 3 months and sit alone at 8 months old. He could not walk alone at 1 year old and underwent 2 months' rehabilitation treatment, and could walk alone and call his parents at 1-and-a-half-years-old. At 4-years-and-10-months-old, he started to have frequent seizures, manifesting as low level of consciousness, body shaking, accompanied by blinking, lasting about a few seconds several times a day and could be relieved. With the treatment of sodium valproate combined with lamotrigine, the convulsions were controlled, but his movement and cognition were lagged behind. DNA sequencing revealed that he has harbored a novel variant of the AP2M1 gene (NM_004068.3) c.508C>T (p.Arg170Trp). Sanger sequencing confirmed that both of his parents were of the wild-type. According to the guidelines from the American College for Medical Genetics and Genomics (ACMG), the variant was rated as pathogenic (PS2+PS4+PM1+PM2+PP2+PP3). The difference between the wild-type and mutant AP2M1 proteins can be clearly viewed through its three-dimensional structure. Two previous reports have included 5 cases due to the same variant. Common manifestations have included seizures (100%, 5/5), motor retardation (100%, 5/5), intellectual impairment (100%, 5/5), autism spectrum disorder (60%, 3/5), ataxia (100%, 5/5), and special facial features (20%, 1/5). CONCLUSION The c.508C>T (p.Arg170Trp) variant of the AP2M1 gene may underlie the intellectual retardation and seizure in this child.

Objective : To investigate the expression of Keratin 14(KRT14) in Basal-like Breast Cancer(BLBC) and its biological functions and mechanisms. Methods : The expression levels of KRT14 mRNA in BLBC and para-cancer breast tissues were analyzed using The Cancer Genome Atlas(TCGA) database. qPCR, Western blot(WB), and immunohistochemistry were employed to detect KRT14 expression in BLBC and adjacent normal tissues, and its correlation with clinicopathological features was analyzed. KRT14 overexpression and knockdown were performed in breast cancer cells, and cell scratch and transwell assays were performed to evaluate changes in migration and invasion abilities. To investigate the expression of proteins related to the Wnt/β-catenin signaling pathway, including catenin Beta 1(β-catenin), wingless-type MMTV integration site family, member 1(Wnt1), matrix metallopeptidase 7(MMP7), and cellular myelocytomatosis viral oncogene homolog(c-Myc), as well as the cellular localization of β-catenin, WB and immunofluorescence(IF) techniques were employed. Additionally, a Wnt/β-catenin signaling pathway inhibitor was used to verify the mechanism of action of KRT14. Results : The expression of KRT14 was significantly higher in BLBC tissues compared to normal tissues(P<0.05), and was associated with higher T stage and histological grade(P<0.05). The overexpression of KRT14 significantly enhanced the migration and invasion abilities of breast cancer cells, while the knockdown of KRT14 significantly reduced those abilities(P<0.01). The overexpression of KRT14 can increase the expression levels of Wnt/β-catenin pathway-related proteins β-catenin, Wnt1, MMP7, and c-Myc, thereby activating the Wnt/β-catenin pathway. Moreover, the inhibition of this pathway can eliminate the effects of KRT14 on cell migration and invasion. Conclusion The high expression of KRT14 in BLBC may promote the migration and invasion of breast cancer cells through the Wnt/β-catenin signaling pathway.
