This paper aimed to investigate the therapeutic effect and mechanism of action of the Yiqi Fumai Formula(YQFM), a kind of traditional Chinese medicine(TCM), on mice with experimental heart failure based on the "heart-gut axis" theory. Based on the network pharmacology integrated with the group collaboration algorithm, the active ingredients were screened, a "component-target-disease" network was constructed, and the potential pathways regulated by the formula were predicted and analyzed. Next, the model of experimental heart failure was established by intraperitoneal injection of adriamycin at a single high dose(15 mg·kg~(-1)) in BALB/c mice. After intraperitoneal injection of YQFM(lyophilized) at 7.90, 15.80, and 31.55 mg·d~(-1) for 7 d, the protective effects of the formula on cardiac function were evaluated using indicators such as ultrasonic electrocardiography and myocardial injury markers. Combined with inflammatory factors in the cardiac and colorectal tissue, as well as targeted assays, the relevant indicators of potential pathways were verified. Meanwhile, 16S rDNA sequencing was performed on mouse fecal samples using the Illumina platform to detect changes in gut flora and analyze differential metabolic pathways. The results show that the administration of injectable YQFM(lyophilized) for 7 d significantly increased the left ventricular end-systolic internal diameter, fractional shortening, and ejection fraction of cardiac tissue of mice with experimental heart failure(P<0.05). Moreover, markers of myocardial injury were significantly decreased(P<0.05), indicating improved cardiac function, along with significantly suppressed inflammatory responses in cardiac and intestinal tissue(P<0.05). Additionally, the species of causative organisms was decreased, and the homeostasis of gut flora was improved, involving a modulatory effect on PI3K-Akt signaling pathway-related inflammation in cardiac and colorectal tissue. In conclusion, YQFM can affect the "heart-gut axis" immunity through the homeostasis of the gut flora, thereby exerting a therapeutic effect on heart failure. This finding provides a reference for the combination of TCM and western medicine to prevent and treat heart failure based on the "heart-gut axis" theory.

BACKGROUND: The association of systemic inflammatory response index (SIRI) with prognosis of coronary artery disease (CAD) patients has never been investigated in a large sample with long-term follow-up. This study aimed to explore the association of SIRI with all-cause and cause-specific mortality in a nationally representative sample of CAD patients from United States. METHODS: A total of 3386 participants with CAD from the National Health and Nutrition Examination Survey (NHANES) 1999-2018 were included in this study. Cox proportional hazards model, restricted cubic spline (RCS), and receiver operating characteristic curve (ROC) were performed to investigate the association of SIRI with all-cause and cause-specific mortality. Piece-wise linear regression and sensitivity analyses were also performed. RESULTS: During a median follow-up of 7.7 years, 1454 all-cause mortality occurred. After adjusting for confounding factors, higher lnSIRI was significantly associated with higher risk of all-cause (HR = 1.16, 95% CI: 1.09-1.23) and CVD mortality (HR = 1.17, 95% CI: 1.05-1.30) but not cancer mortality (HR = 1.17, 95% CI: 0.99-1.38). The associations of SIRI with all-cause and CVD mortality were detected as J-shaped with threshold values of 1.05935 and 1.122946 for SIRI, respectively. ROC curves showed that lnSIRI had robust predictive effect both in short and long terms. CONCLUSIONS SIRI was independently associated with all-cause and CVD mortality, and the dose-response relationship was J-shaped. SIRI might serve as a valid predictor for all-cause and CVD mortality both in the short and long terms.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA

Objective:To evaluate the association between erectile dysfunction(ED)and myocardial infarction(MI)using two sample Mendelian randomization.Methods:A Mendelian randomization study was conducted using comprehensive data on ED and MI from extensive genome-wide association data.Using inverse variance weighted analysis for causal relationships,and correct for confounding factors using multivariate Mendelian randomization,the potential mediating effects were evaluated as well.Based on Gene-card data,the genes related to ED and MI were identified.Molecular docking was used to reveal spontaneously bound drug molecules.Results.Our study found that exposure to ED was a risk factor for MI(OR:1.001 0,95％CI:1.000 2-1.001 8,P=0.017 7),which also held true in the validation dataset(OR:1.028 5,95％CI:1.005 0-1.052 6,P=0.017 2).No statistically significant heterogeneity or horizontal pleiotropy was found.The results of reverse Mendelian randomization analysis showed any reverse causal re-lationship between ED and MI.In multivariate Mendelian randomization analysis,after excluding confounding factors(excluding tri-glycerides and high-density lipoprotein),the P-value remained less than 0.05,and the OR ranged from 1.000 1 to 1.000 7,indica-ting that ED was still a risk factor for MI.In the mediation analysis,it was found that the current mediation ratio of smoking to MI was 13.06％.In summary-data-based mendelian randomization analysis,it was found that the gene PTPN11 was a common target gene for MI and ED(OR=0.990,P＜0.001).Subsequent molecular docking with sildenafil,clopidogrel,and dapoxetine could spontaneous-ly bind to the PTPN11 gene receptor.Conclusion:There is a causal relationship between ED and MI,with smoking as a potential mediating factor,and the gene PTPN11 being a co-target gene.

Objective To construct a diagnostic model based on the information of the TCM four diagnoses in hyperactive liver yang syndrome in patients with essential hypertension.Methods Syndromic investigation was carried out in patients with essential hypertension in some hospitals in Fujian and Beijing,and diagnostic information such as age,gender,symptoms,tongue and pulse were collected.On the basis of statistical analysis,this study adopted C5.0,CRT,CHAID and QUEST decision tree models respectively.After evaluating the stability and performance consistency of the models,the accuracy of the models was measured by diagnostic rate,and the optimal model of hyperactivity of liver yang in essential hypertension was selected.Results Totally 533 patients with essential hypertension were included,including 198 patients with hyperactive liver yang syndrome and 335 patients without hyperactive liver yang syndrome.The diagnostic rates of the four models were 75.2%,66.2%,67.7%and 65.0%,respectively.The diagnostic efficiency of C5.0 was better than that of CRT,CHAID and QUEST models."Aggravation after emotional excitement,poor complexion,string-like pulse,irritability,head swelling pain,bitter mouth,heavy pulse,fatigue,dark tongue,irritability,dizziness,thin pulse,yellow fur"could be regarded as the specific items of the syndrome model of hyperactive liver yang in essential hypertension.Conclusion The C5.0 decision tree model can clearly and intuitively identify the hyperactive liver yang syndrome in essential hypertension patients based on clinical TCM four diagnostic information data,and summarize diagnostic rules.

Objective:To evaluate the efficacy and safety of antaitasvir phosphate 100 mg or 200 mg combined with yiqibuvir for 12 weeks in patients with various genotypes of chronic hepatitis C, without cirrhosis or compensated stage cirrhosis.Methods:Patients with chronic hepatitis C (without cirrhosis or compensated stage cirrhosis) were randomly assigned to the antaitasvir phosphate 100 mg+yiqibuvir 600 mg group (100 mg group) or the antaitasvir phosphate 200 mg+yiqibuvir 600 mg group (200 mg group) in a 1∶1 ratio. The drugs were continuously administered once a day for 12 weeks and observed for 24 weeks after drug withdrawal. The drug safety profile was assessed concurrently with the observation of the sustained virological response (SVR12) in the two patient groups 12 weeks following the drug cessation. The intention-to-treat concept was used to define as closely as possible a full analysis set, including all randomized cases who received the experimental drug at least once. The safety set was collected from all subjects who received the experimental drug at least once (regardless of whether they participated in the randomization group) in this study. All efficacy endpoints and safety profile data were summarized using descriptive statistics. The primary efficacy endpoint was SVR12. The primary analysis was performed on a full analysis set. The frequency and proportion of cases were calculated in the experimental drug group (antaitasvir phosphate capsules combined with yiqibuvir tablets) that achieved "HCV RNA

Objective To investigate the effects of leptin on hypothalamic neuron activity and lipid metabolism in adipose tissue of obese mice.Methods 10 leptin-deficient obese(ob/ob)mice with homozygous mutation of leptin gene and 10 wild-type(WT)mice born in the same litter were randomly divided into control group and leptin treatment group.The activity of pro-opiomelanocortin(POMC)neurons and tyrosine hydroxylase(TH+)neurons,the morphological changes of adipose tissue and the expression of lipid-related genes were analyzed by immunofluorescent staining,HE staining and Real-time PCR.Results Compared with the WT mice,the ob/ob mice showed decreased activity of POMC neurons and TH+neurons and larger cell diameter in adipose tissue and liver tissue.In addition,the expressions of heat-related genes uncoupling protein 1(UCP1),cytochrome c oxidase subunit 8B(Cox8b)and cell death-inducing DNA fragmentation factor,alpha subunit-like effector A(Cidea)in subcutaneous white fat in ob/ob mice decreased significantly,and the expressions of lipid synthesis-related genes sterol regulatory element binding transcription factor 1(Srebp1)and fatty acid synthase(Fas)increased significantly.After treated with leptin,the activities of POMC and TH+neurons were increased,and the cellular diameter and the degree of vacuolar degeneration were reduced in the adipose tissue and liver.Further analyses showed that the expressions of thermogenesis-related genes and lipolysis-related genes were increased,but expressions of lipid synthesis-related genes were reduced in brown adipose tissue.Conclusion Leptin treatment could prevent the increasing of obesity in ob/ob mice,which is associated with increased lipolysis and reduced lipid synthesis through activation of hypothalamic POMC neurons and peripheral adipose tissue sympathetic nervous system.
