ObjectiveTo observe the effect of gastrodin on the steroid regulatory element-binding protein 1c （SREBP1c） signaling pathway in high-fat high-cholesterol diet （HFHC）-induced mice and explore the mechanism of gastrodin in the treatment of non-alcoholic fatty liver disease （NAFLD）. MethodEight-week-old male C57BL/6J mice were used in vivo and divided into the following four groups， with six mice in each group： normal group， gastrodin group （50 mg·kg^-1）， model group， and model + gastrodin group （50 mg·kg^-1）. NAFLD model was established by feeding mice with HFHC for four weeks， and the mice were euthanized and the liver tissues were collected after four weeks. In vitro experiments were performed using Huh7 cells which were divided into five groups， and induced with free fatty acids （FFA， 200 μmol·L^-1， oleic acid-palmitic acid 2∶1） to establish an NAFLD cell model. After 24 h， different concentrations of gastrodin （0， 5， 10， 20， and 40 μmol·L^-1） were added to each group and cultured for another 24 h. Oil red O staining was used to detect lipid accumulation in mouse liver and Huh7 cells. Hematoxylin-eosin （HE） staining was used to observe pathological changes in liver tissue. Levels of serum total cholesterol （TC）， low-density lipoprotein cholesterol （LDL-C）， and triglycerides （TG） were measured using an automatic biochemical analyzer. Relevant assay kits were used to detect liver TC， TG， and FFA levels. Real-time quantitative polymerase chain reaction （Real-time PCR） and Western blot were used to detect the expression of lipid synthesis-related proteins fatty acid synthase （FASN）， acetyl-CoA carboxylase 1 （ACC1）， and stearoyl-CoA desaturase 1 （SCD1）. ResultCompared with the normal group， the model group showed significantly increased serum TC， LDL-C， and TG levels （P<0.01）， liver TC， TG， and FFA levels （P<0.01）， increased lipid accumulation in Huh7 cells （P<0.01）， and significantly increased expression levels of lipid synthesis-related genes SREBP1c， FASN， ACC1， and SCD1 in mice and Huh7 cells （P<0.01）. Compared with the model group， after gastrodin treatment， the serum TC， LDL-C， and TG levels in mice significantly decreased （P<0.05， P<0.01）， the severity of fatty liver disease improved significantly， liver TC， TG， and FFA levels decreased significantly （P<0.05， P<0.01）， lipid accumulation in Huh7 cells decreased significantly （P<0.05， P<0.01）， the expression levels of lipid synthesis-related genes SREBP1c， FASN， ACC1， and SCD1 in mice and Huh7 cells decreased significantly （P<0.05， P<0.01）. ConclusionGastrodin can reduce hepatic lipid accumulation and blood lipid levels， improve HFHC-induced NAFLD， and its mechanism of action may be related to the regulation of the SREBP1c lipid synthesis-related signaling pathway.

The human body's structure and function are complex,encompassing five viscera,six bowels,as well as differences in qi,blood,yin,and yang.However,the fundamental life activity primarily relies on the body's yang.Physiologically,when the body has sufficient yang and smooth blood circulation without stagnation,the five organs are nourished,ensuring their proper function.Conversely,pathologically,the deficiency of yang caused by cold injury leads to blood stagnation and prolonged stasis,resulting in inadequate nourishment of the five viscera and subsequent dysfunction.Depression is a condition that can be triggered by cold condensation and blood stasis.Acupuncture treatment follows the principle of warming yang and activating blood circulation.Key acupuncture points such as Baihui(GV20),Dazhui(GV14),Zhiyang(GV9),Mingmen(GV4),Guanyuan(CV4),and Zusanli(ST36)are used to warm yang and replenish qi,while Xuehai(SP10),Weizhong(BL40),and Sanyinjiao(SP6)are utilized to activate blood circulation and open up the veins.Additionally,supplementary points like Danzhong(CV17),Zhongwan(CV12),Qihai(CV6),Hegu(LI4),and Taichong(LR3)are employed to regulate qi and alleviate stagnation,facilitating the smooth flow of qi and blood.This comprehensive approach addresses both the symptoms and the root cause,simultaneously addressing deficiencies and replenishing the body.It aims to restore deficient yang,resolve blood stasis,promote the full and calm flow of qi and blood,nourish the five viscera and restore their proper function,ultimately leading to the self-healing of depression.

BACKGROUND:Previous studies have reported inconsistent results with positive,negative,and J-shaped associations between alcohol consumption and the hazard of aortic aneurysm and dissection(AAD).This study aimed to examine the connections between weekly alcohol consumption and the subsequent risk of AAD. METHODS:The UK Biobank study is a population-based cohort study.Weekly alcohol consumption was assessed using self-reported questionnaires and the congenital risk of alcohol consumption was also evaluated using genetic risk score(GRS).Cox proportional hazards models were used to estimate hazard ratios(HRs)with 95%confidence intervals(CIs)for the associations between alcohol consumption and AAD.Several sensitivity analyses were performed to assess the robustness of the results. RESULTS:Among the 388,955 participants(mean age:57.1 years,47.4%male),2,895 incident AAD cases were documented during a median follow-up of 12.5 years.Compared with never-drinkers,moderate drinkers(adjusted HR:0.797,95%CI:0.646-0.984,P<0.05)and moderate-heavy drinkers(adjusted HR:0.794,95%CI:0.635-0.992,P<0.05)were significantly associated with a decreased risk of incident AAD.Interaction-based subgroup analysis revealed that the protective effect of moderate drinking was reflected mainly in participants younger than 65 years and women. CONCLUSION:Our findings support a protective effect of moderate alcohol consumption on AAD,but are limited to participants younger than 65 years and women.

OBJECTIVE To construct a clinical model of motion sickness(MS),provide a relatively objective diagnostic model for MS research,and provide a basis for further clinical intervention of the disease.METHODS A total of 60 subjects were included and divided into experimental group and control group according to the presence or absence of MS.The MS clinical model was established using SRM-IV rotating chair.Peripheral blood was collected before and after acceleration exposure,and the contents of adrenocorticotropic hormone(ACTH),growth hormone(GH),prolactin(PRL),follicle stimulating hormone(FSH),luteinizing hormone(LH),thyroid stimulating hormone(TRH)and gastrin-17(G-17),acetylcholine(ACH)and 5-hydroxytryptamine(5-HT)were detected,Graybiel scale was used to evaluate the severity of MS.The correlation between MS symptoms and signs and peripheral blood indexes was analyzed by multiple linear regression,and the diagnostic model was established.construct a clinical model of MS and a diagnostic model based on blood parameters,so as to provide a reliable clinical model and an objective diagnostic model for MS research,and to provide a basis for further clinical intervention of the disease.RESULTS After acceleration exposure,the Graybiel scores,ACH,5-HT,ACTH,GH and PRL levels in peripheral blood of the experimental group were higher than those before exposure,and were significantly different from those of the control group(P<0.001).There was no significant difference in FSH,LH,TRH and G-17 between the two groups before and after acceleration exposure(P>0.05).Multi-index combined diagnostic model:Graybiel scores=-9.32+0.131×ACTH+0.055×ACH+0.041×5-HT.CONCLUSION The levels of ACH,5-HT,ACTH,GH and PRL increased during the onset of MS.The multi-index combined diagnosis model can provide a certain basis for the objective diagnosis of MS in clinical practice.

OBJECTIVE To identify key factors involved in the regulation of hypoxia-induced inflammation-related signaling pathways using a combination of bioinformatics methods and experiments. METHODS A cellular model of hypoxia-induced hippocampal neuronal damage was prepared by treating mouse hippocampal neuronal HT22 cells with CoCl2. The cells were then collected for transcriptome sequencing. Based on the sequencing results,key molecules were identified using differential analysis,gene ontology(GO) function and Kyoto Encyclopedia of Genomes(KEGG) pathway analysis,and protein-protein interaction network(PPI) analysis. The effects of key molecules on cells were investigated. RESULTS Differential analysis revealed a total of 8975 differential genes,which were subjected to GO and KEGG analysis. KEGG analysis revealed that these genes were involved in signaling pathways such as pancreatic cancer,EGFR tyrosine kinase inhibitor resistance,animal mitosis,base excision repair,and chronic myeloid leukemia. PPI networks were constructed for genes enriched in these pathways,and the MCC algorithm screened the top 5 key genes,which were shown to be HRAS,KRAS,PTEN,VEGFA,and SRC. HRAS and VEGFA were selected for subsequent experiments,and the results showed that after CoCl2 treatment,the viability of HT22 cells was significantly decreased(P<0.05),HRAS was significantly down-regulated and VEGFA was significantly up-regulated in CoCl2-treated cells(P<0.05),the levels of TNF-α,IL-1β,and IL-6 were significantly increased(P<0.001). However,treatment with overexpression of HRAS or low expression of VEGFA led to an increase in the activity of cell growth(P<0.05) as well as a significant decrease in TNF-α,IL-1β,and IL-6 levels(P<0.001). CONCLUSION In sleep apnea,HRAS or VEGFA may lead to cognitive impairment by affecting inflammatory factors.
