ObjectiveTo study the therapeutic mechanism of Xihuang Wan for hyperplasia of mammary glands based on network pharmacology, molecular docking, and cell experiments. MethodsThe active ingredients and targets of Xihuang Wan were retrieved from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and A Bioinformatics Annotation daTabase for Molecular mechANism of Traditional Chinese Medicine (BATMAN-TCM) and supplemented by searching against PubChem and Swiss Target Prediction. The targets of differential metabolites in tissues and urine were obtained from previous metabolomics studies through PubChem and Swiss Target Prediction. GeneCards, Online Mendelian Inheritance in Man (OMIM), PharmGKB, Therapeutic Target Database (TTD), Drunbank were searched for the targets of hyperplasia of mammary glands. After the common targets were obtained via Veeny2.1.0, the STRING database was used to analyze the protein-protein interactions, and Cytoscape was used for the core target analysis and visualization. Gene Ontology (GO) and the Kyoto Encyclopedia of Genes and Genomes (KEGG) were employed for enrichment analysis. Molecular docking was carried out in Autodock, and cell experiments were conducted to verify the prediction results. In the cell experiments, estradiol and progesterone (E2+P) were used to intervene in human mammary epithelial/MCF-10A cells, and thus the MCF-10A cell proliferation model was established. The cells were then treated with Xihuang Wan-medicated serum. The cell counting kit-8 (CCK-8) was used to measure the cell proliferation, and flow cytometry was used to detect apoptosis. The mRNA and protein levels of key factors in MCF-10A cells were determined by real-time PCR and Western blot, respectively. ResultsThe results of network pharmacology showed that 90 active ingredients and 316 common targets were obtained, from which 20 core targets and 38 corresponding active ingredients were screened out. The results of GO and KEGG enrichment analyses showed that Xihuang Wan exerted effect against hyperplasia of mammary glands by regulating a variety of biological processes, which may be related to protein kinase B (Akt)-related molecular functions, estrogen signaling pathway, prolactin signaling pathway and other biological processes. The results of molecular docking showed that estrogen receptor 1 (ESR1), serine/threonine kinase 1 (Akt1), non-receptor tyrosine kinase (SRC), and signal transducer and activator of transcription 3 (STAT3) all had strong binding activity with the nine active ingredients, suggesting that Xihuang Wan exert the effect through the ESR1/SRC/phosphatidylinositol 3-kinase (PI3K)/Akt signaling pathway and the Janus kinase (JAK)/STAT3 signaling pathway. The results of cell experiments showed that E2+P intervention in MCF-10A cells promoted the proliferation of MCF-10A cells (P<0.05), while the Xihuang Wan-medicated serum inhibited the proliferation of MCF-10A cells exposed to E2+P (P<0.05). Flow cytometry showed that the Xihuang Wan-medicated serum promoted the apoptosis of MCF-10A cells exposed to E2+P (P<0.01). The results of Real-time PCR showed that the Xihuang Wan-medicated serum down-regulated the mRNA levels of PI3K, Akt, JAK2, and STAT3 in MCF-10A cells treated with E2+P (P<0.01). The results of Western blot showed that the Xihuang Wan-medicated serum inhibited the expression of p-PI3K/PI3K, p-Akt/Akt, p-JAK2/JAK2, and p-STAT3/STAT3 in MCF-10A cells treated with E2+P (P<0.05). ConclusionXihuang Wan may exert the effect against hyperplasia of mammary glands by inhibiting the proliferation and promoting the apoptosis of MCF-10A cells, which may related to the inhibition of the activation of PI3K/Akt and JAK2/STAT3 signaling pathways.

【Objective】 To analyze the height growth of children aged 6 - 15 years in Nanning, Guangxi Zhuang Autonomous Region, so as to provide evidence for the assessment of local children′s height development. 【Methods】 A total of 25 225 children aged 6 - 15 years were selected to get their physical examination data from 41 primary schools in Nanning by stratified cluster sampling method in December 2021.Then the height data were compared with the current domestic standards. 【Results】 The average height of boys in Nanning was lower than the national standard before the age of 10 years and 7 months, and the gap with the national standard gradually narrowed after the age of 10 years and 7 months. The average height of boys in Nanning City exceeded the national standard between the age of 11 years and 1 month and 13 years and 6 months, and then lagged behind the national standard again after the age of 13 years and 7 months. The mean height of girls in Nanning City was lower than the national standard height in several age groups, and it was more obvious before the age of 9 years and 7 months. The proportion of height ≤-2s,≤-s,≥ +s and ≥+2s in boys aged 6 to 15 years in Nanning City fluctuated from 2.59% to 6.04%, 12.09% to 23.43%, 7.18% to 18.79% and 0.93% to 3.14%, respectively; the total proportions were 4.56%, 17.46%, 11.35% and 1.74%, respectively; the minimum/maximum proportion values of each height group were at 11 years old /8 years old, 14 years old/8 years old, 8 years old/12 years old, and 6 years old/11 years old, respectively. The proportions of girls aged 6 - 15 years in Nanning City with height ≤-2s, ≤-s, ≥+s, and ≥+2s fluctuated from 2.06% to 5.19%, 9.35% to 25.15%, 8.21% to 15.80% and 1.23% to 3.49%, respectively; the total proportions were 3.38%, 16.91%, 11.97% and 2.29%, respectively; and the minimum/maximum proportion values of each height group were at 13 years old/6 years old, 12 years old/6 years old, 7 years old/12 years old, and 6 years old/11 years old, respectively. 【Conclusions】 The overall height level of children in Nanning is still lower than the national level, with short prepubertal basal heights, an earlier age of onset of accelerated pubertal height, and a shorter duration of accelerated pubertal height in boys. Strengthening pre-pubertal height management and emphasizing the onset and duration of children′s pubertal development, especially the height development of boys during puberty, can help improve the adult lifelong height of children in this region.

Dysregulation of histone deacetylases (HDACs) is closely related to tumor development and progression. As promising anticancer targets, HDACs have gained a great deal of research interests and two decades of effort has led to the approval of five HDAC inhibitors (HDACis). However, currently traditional HDACis, although effective in approved indications, exhibit severe off-target toxicities and low sensitivities against solid tumors, which have urged the development of next-generation of HDACi. This review investigates the biological functions of HDACs, the roles of HDACs in oncogenesis, the structural features of different HDAC isoforms, isoform-selective inhibitors, combination therapies, multitarget agents and HDAC PROTACs. We hope these data could inspire readers with new ideas to develop novel HDACi with good isoform selectivity, efficient anticancer effect, attenuated adverse effect and reduced drug resistance.
