Ketosis is an energy metabolism disorder occurring frequently in periparturient dairy cows,primarily attributed to elevated non-esterified fatty acid(NEFA)levels resulting from nega-tive energy balance(NEB).Excessive NEFA will be incompletely oxidated into large amounts of ketone bodies or be re-esterified and deposit in the liver as a consequence of hepatic limited oxida-tive capacity,ultimately leading to ketosis and fatty liver.Hypoxic microenvironments are com-monly found during the progression of various liver diseases.Hypoxia inducible factor-2 alpha(HIF-2 alpha)has been identified as a crucial regulator of lipid metabolism.However,it is still un-clear the association between HIF-2α and disrupted lipid metabolism in the livers of in ketotic cows.This study aims to investigate the effect of high concentrations of NEFA on HIF-2α expres-sion and cellular oxygen homeostasis through bovine liver tissue and primary hepatocytes.In vivo,hepatic triglyceride(TAG)content was assessed to determine the extent of hepatic lipid accumula-tion,and HIF-2α protein and mRNA levels were analyzed by immunohistochemistry staining,Western blot and qRT-PCR assay in liver tissue samples from dairy cows;in vitro,bovine primary hepatocytes were treated with different concentrations of NEFA.Oil Red O staining and TAG con-tent assay were performed to determine hepatocellular steatosis extent,and immunofluorescence staining.Western blot,and qRT-PCR were performed to analyze HIF-2α expression,in addition,lu-minescent oxygen sensor[Ru(dpp)3]Cl2 was added to indicate intracellular oxygen levels.These results showed a significant increase in TAG content and elevated HIF-2α expression in the liver tissue of ketotic cows,and high concentrations of NEFA induced lipid accumulation,upregulation of HIF-2α expression,and intracellular hypoxia in bovine primary hepatocytes.These findings sug-gested that HIF-2α was significantly"activated"in the liver of ketotic cows and high concentration of NEFA-induced bovine primary hepatocytes,and that high concentrations of NEFA induced in-tracellular hypoxia in vitro.This study provides a potential molecular target for further investiga-tion of the mechanism underlying hepatic lipid metabolism disorders in ketotic cows.

Acupuncture and moxibustion therapy is a kind of treatment and health care method with original advantages of China.With the rapid development of epigenetics and systems biology technology,non-coding RNA(ncRNA)related research has made continuous breakthroughs in the field of acupuncture and moxibustion.This article collected the basic research literature on acupuncture and moxibustion related to ncRNA,and reviewed the research subsystems related to microRNA(miRNA),long chain non coding RNA(lncRNA)and circular RNA(circRNA).NcRNAs are widely involved in the growth,development and reproduction of the organism,as well as in the occurrence and development of various diseases,which fits with the multi-layer,multi-pathway and multi-target action network of acupuncture and moxibustion therapy.Taking ncRNAs as the breakthrough point to explore the mechanism of acupuncture and moxibustion in depth is not only conducive to promoting the exploration of new targets of acupuncture and moxibustion effect,but also can reveal the epigenetic regulation axis of acupuncture and moxibustion effect molecules,and provide ideas and methods for clinical diagnosis and treatment of diseases and evaluation of efficacy.

AIM:To exploring the mechanism of Xin Mai Jia(XMJ)in inhibiting hypertensive cardiac hypertrophy through network pharmacology and animal experiments.METHODS:Retrieving the ac-tive ingredients and target points of XMJ by search-ing the TCMSP database and related literature re-ports;using the Gene Cards,OMIM,and Drug Bank databases to screen targets for hypertensive cardi-ac hypertrophy;constructing a network of tradi-tional Chinese medicine-active ingredients-poten-tial targets and a protein-protein interaction(PPI)network;using DAVID software for target gene on-tology(GO)functional enrichment analysis and Kyo-to Encyclopedia of Genes and Genomes(KEGG)pathway enrichment analysis;using Auto Dock soft-ware for molecular docking.A spontaneously hy-pertensive rat(SHR)model was established,and hematoxylin-eosin(HE)staining was used to detect the morphology of cardiac tissue and cellular hy-pertrophy,Masson staining was used to detect col-lagen deposition in cardiac tissue,and Western blot to detect the expression of heat shock protein(HSP90AA1),mammalian target of rapamycin(mTOR),peroxisome proliferator-activated receptor y(PPARG),and tumor necrosis factor(TNF-α)in car-diac tissue.RESULTS:A total of 56 potential active ingredients were identified in XMJ,and 5,492 tar-gets related to hypertensive cardiac hypertrophy were obtained.The targets in the core network were ranked according to their Degree values,and four main targets were selected:HSP90AA1,mTOR,PPARG,and TNF-α.The results of HE staining showed that compared with the normal group,the average area of cardiomyocytes in the SHR group increased significantly(P＜0.05),while there was no significant change in the XMJ group.The hypertro-phy in the SHR+XMJ group was significantly alleviat-ed(P＜0.05).The results of Masson staining showed that compared with the normal group,the levels of interstitial fibrosis and perivascular fibrosis in the SHR group rats increased significantly(P＜0.01),and XMJ could significantly reduce the fibrosis levels in the SHR group rats(P＜0.01).The results of Western blot showed that compared with the normal group rats,the expression of HSP90AA1 and PPARG in the myocardial tissue of SHR group rats was downregu-lated,mTOR phosphorylation was downregulated,and TNF-α was significantly upregulated(P＜0.01).In the SHR+XMJ group,the expression of HSP90AA1,PPARG,and TNF-α in the myocardial tis-sue of rats returned to normal levels,and mTOR phosphorylation returned to normal levels.In the XMJ group,there were no significant changes in the above indicators compared with the normal group rats.CONCLUSION:The mechanism underly-ing the inhibitory effect of XMJ on myocardial cell hypertrophy in hypertension involves a comprehen-sive action through multiple components,multiple targets,and multiple pathways.
