Objective To explore the mechanism of electroacupuncture in improving lipid metabolism in polycystic ovary syndrome(PCOS)based on metabolomics combined with transcriptomics.Methods Eight-een SD rats were divided into the control group,the PCOS group and the electroacupuncture group,with 6 rats in each group.The PCOS group and the electroacupuncture group used intragastric letrozole to establish the PCOS model.After the model was established,the electroacupuncture group was intervened with electroacu-puncture,while the control group was only given sodium carboxymethyl cellulose by gavage.Observed the changes in body weight and estrous cycle of the three groups,detected the sex hormones,blood lipids,liver function,ovarian morphology,plasma metabolism and liver function indicators of the three groups.Metabolo-mics was used to analyze the differences in metabolites in plasma,the differences in gene expression in the liv-er were detected by RT-qPCR.Results Weight gain and estrous cycle disorder occurred in the PCOS group,and the ovarian morphology showed a thinning of the granulosa cell layer,with a significant reduction in the number of corpus luteum and mature follicles.Meanwhile,sex hormones were abnormal(total testosterone and androgen levels were increased,estradiol and progesterone levels were decreased),dyslipidemia occurred(TC,TG,LDL-C were increased,HDL-C level was decreased),and liver function was abnormal(AST,total protein,ALB,TBIL were increased).The electroacupuncture group significantly reduced weight.It improved the estrous cycle,and the granulosa cell layer of the ovary thickened,with a significant increasing in the num-ber of corpus luteum and mature follicles.Meanwhile,sex hormone levels were improved(androgen and total testosterone levels were decreased,estradiol level was increased),lipid balance(TC,TG,LDL-C levels were reduced,HDL-C level was increased)and liver function(AST,total protein,ALB,and TBIL levels were de-creased)was restored.Transcriptomics suggested that electroacupuncture down-regulated the expression of cytochrome P450(CYPs)family genes related to steroid hormones and lipid metabolism,and the results were confirmed by RT-qPCR.Combined omics analysis revealed that electroacupuncture might mainly exert its effect on improving lipid metabolism disorders in PCOS rats through the linoleic acid metabolic pathway.Con-clusion Electroacupuncture can regulate lipid metabolism in rats with PCOS.

Emodin is a hydroxyanthraquinone compound that is widely distributed and has multiple pharmacological activities, including anti-diarrheal, anti-inflammatory, and liver-protective effects. Research indicates that emodin may be one of the main components responsible for inducing hepatotoxicity. However, studies on the mechanisms of liver injury are relatively limited, particularly those related to bile acids(BAs) metabolism. This study aims to systematically investigate the effects of different dosages of emodin on BAs metabolism, providing a basis for the safe clinical use of traditional Chinese medicine(TCM)containing emodin. First, this study evaluated the safety of repeated administration of different dosages of emodin over a 5-week period, with a particular focus on its impact on the liver. Next, the composition and content of BAs in serum and liver were analyzed. Subsequently, qRT-PCR was used to detect the mRNA expression of nuclear receptors and transporters related to BAs metabolism. The results showed that 1 g·kg~(-1) emodin induced hepatic damage, with bile duct hyperplasia as the primary pathological manifestation. It significantly increased the levels of various BAs in the serum and primary BAs(including taurine-conjugated and free BAs) in the liver. Additionally, it downregulated the mRNA expression of farnesoid X receptor(FXR), retinoid X receptor(RXR), and sodium taurocholate cotransporting polypeptide(NTCP), and upregulated the mRNA expression of cholesterol 7α-hydroxylase(CYP7A1) in the liver. Although 0.01 g·kg~(-1) and 0.03 g·kg~(-1) emodin did not induce obvious liver injury, they significantly increased the level of taurine-conjugated BAs in the liver, suggesting a potential interference with BAs homeostasis. In conclusion, 1 g·kg~(-1) emodin may promote the production of primary BAs in the liver by affecting the FXR-RXR-CYP7A1 pathway, inhibit NTCP expression, and reduce BA reabsorption in the liver, resulting in BA accumulation in the peripheral blood. This disruption of BA homeostasis leads to liver injury. Even doses of emodin close to the clinical dose can also have a certain effect on the homeostasis of BAs. Therefore, when using traditional Chinese medicine or formulas containing emodin in clinical practice, it is necessary to regularly monitor liver function indicators and closely monitor the risk of drug-induced liver injury.

Objective:To analyze the trend of lipid changes in patients and individuals undergoing physical examination at Zhongshan Hospital of Fudan University from 2014 to 2024, providing evidence for the formulation of cardiovascular disease prevention and control strategies.Methods:A total of 2 657 835 individuals (general population) who underwent lipid testing during medical visits or physical examinations at Zhongshan Hospital of Fudan University from January 1, 2014, to December 31, 2024, were selected. Among them, 6 234 individuals who were tested consecutively for 11 years were considered as the fixed population. Lipid levels were analyzed across different genders and age groups. Total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), and high-density lipoprotein cholesterol (HDL-C) were analyzed. The trends in lipid changes and the abnormal rates of TC (≥5.18 mmol/L) and LDL-C (≥3.40 mmol/L) in both the general and fixed populations were statistically analyzed.Results:The median age of the general population was 53 (41, 63) years, with 1 498 533 males (56.4%); 1 149 662 individuals (43.3%) were from the physical examination group. The median age of the fixed population was 52 (39, 62) years, with 3 262 males (52.3%); 2 955 individuals (47.4%) were from the physical examination group. Over an 11-year period, the logarithmically transformed TG (lnTG) in the general population slightly increased from 1.35 mmol/L to 1.36 mmol/L (Sen slope=0.007 mmol·L -1·year -1; S=27, P=0.043). Although there were fluctuations in TC, LDL-C, and HDL-C, the trends were not statistically significant ( P>0.05). However, in the subset of the population undergoing regular health check-ups, TC showed a steady increase over time ( S=27, P=0.043). Within a fixed population over the same 11-year period, there were no statistically significant changes in lipid profiles ( P>0.05). Nevertheless, in the fixed subset undergoing regular health check-ups, both TC and lnTG exhibited an upward trend (TC: S=27, P=0.043; lnTG: S=31, P=0.020), while in the fixed subset seeking medical attention, TC and LDL-C demonstrated a downward trend (TC: S=-31, P=0.020; LDL-C: S=-27, P=0.043). Trends in lipid profiles varied among different genders and age groups. Specifically, both men and women aged 20-<40 years old showed an increase in TC, abnormal TC rates, and abnormal LDL-C rates ( P<0.05). Conversely, in the fixed population, women over 60 years old exhibited a decrease in TC, abnormal TC rates, and abnormal LDL-C rates ( P<0.05). Conclusion:During the period from 2014 to 2024, there were slight fluctuations in the average lipid levels of both the general and fixed populations. Notably, TC, abnormal TC rates, and abnormal LDL-C rates increased among men and women aged 20-<40 years old, while these parameters decreased among women over 60 years old in the fixed population.
