Objective:To investigate the association between estimated cumulative low-density lipoprotein cholesterol (LDL-C) exposure and the severity of coronary artery disease and long-term adverse cardiovascular and cerebrovascular events (MACCE) in patients with acute coronary syndrome (ACS).Methods:The subjects were from the PROMISE study. This study was a prospective cohort study led by Fuwai Hospital, Chinese Academy of Medical Sciences, with participation from eight regional tertiary hospitals as sub-centers, and enrolled 18 701 patients with confirmed coronary heart disease between January 2015 and May 2019. Among them, 8 429 patients with ACS were included in this study. The estimated cumulative LDL-C exposure was calculated by multiplying LDL-C by age. Participants were then divided into four groups based on quartiles. Baseline data and coronary angiography data were collected, and participants were followed for 2 years. The primary endpoint was MACCE, which was composed of all-cause death, cardiac death, myocardial infarction, revascularization, and stroke. Spearman correlation analysis was used to estimate the correlation between cumulative LDL-C exposure and the severity of coronary artery disease. The differences in MACCE among the four groups were compared, and multivariate Cox regression was used to divide the estimated cumulative exposure LDL-C into two groups, three groups, and four groups to analyze its relationship with MACCE.Results:The 8 429 ACS patients included in the study had an age of (60.9±11.4) years, with 1 951(23.1%) females. Spearman correlation analysis revealed that estimated cumulative LDL-C exposure was positively associated with the preoperative SYNTAX score, three-vessel lesions disease, left main disease, and the number of target lesions (correlation coefficients r=0.14, 0.10, 0.04 and 0.03, respectively, with all P<0.05). The 2-year follow-up results indicated that the incidence rates of MACCE, all-cause death, cardiac death, myocardial infarction, and stroke in ACS patients grouped by different levels of estimated cumulative LDL-C exposure were statistically significant (all P<0.05). The results of the Cox multivariate regression analysis showed that when the estimated cumulative LDL-C exposure was treated as a continuous variable and analyzed in two, three, and four groups, with the lowest group as the reference, the risk of MACCE occurrence in the high-value group increased by 21% (95% CI 1.08-1.37, P=0.002), 24% (95% CI 1.07-1.43, P=0.004), and 21% (95% CI 1.02-1.43, P=0.025) respectively. Conclusions:A positive correlation was found between estimated cumulative LDL-C exposure and severity of coronary artery disease. High estimated cumulative LDL-C exposure level is a risk factor for MACCE in ACS patients within 2 years.

Objective:To explore the influencing factors of clinical pregnancy outcomes in patients with hydrosalpinx undergoing in vitro fertilization-embryo transfer(IVF-ET) after interventional embolization and whether residual hydrops has an adverse impact on pregnancy outcomes.Methods:Clinical data from 65 patients who underwent interventional embolization and IVF-ET for hydrosalpinx at the Third Affiliated Hospital of Zhengzhou University from March 2021 to October 2022 were collected retrospectively. The hydrops index was quantified by the ratio of the widest diameter to the pelvic transverse diameter of the intraoperative hydrops, and the patient′s age, body mass index(BMI), follicle-stimulating hormone(FSH), lutenizing hormine(LH), estradiol(E2), automated matetials hangling(AMH), endometrial thickness at the time of transplantation, the number of transplanted embryos, embryo type, and location of the hydrosalpinx were recorded. In addition, the clinical pregnancy outcomes of the first transplantation after embolization were followed. Two independent samples t-test, rank sum test and chi-square test were used to analyze the difference of the above indexes among different clinical pregnancy outcomes by SPSS 25.0. The receiver operating characteristic (ROC) curves and Youden index were used to calculate the cut-off value of the water accumulation index. Results:Among 65 patients, the clinical pregnancy rate was 63.1%(41/65), among the 45 patients who underwent embryo transfer before embolization without success, the clinical pregnancy rate after embolization was 62.2%(28/45). Based on data analysis, it showed that IVF-ET clinical pregnancy outcomes were not associated with age, BMI, FSH, LH, E2, AMH, endometrial thickness at the time of transplantation, the number of transplanted embryos, embryo type, as well as location of hydrosalpinx( P>0.05), but associated with hydrosalpinx index( P<0.001). ROC curve analysis showed that the hydrops index could be used as a predictor of pregnancy outcome, and the area under the curve was 0.825, and the optimal cut-off value of the hydrops index was 12.925% based on the Youden index analysis result. Conclusions:Interventional embolization of hydrosalpinx may improve clinical pregnancy rates. When the hydrosalpinx is large enough, it could adversely affected IVF-ET clinical pregnancy, and further aspiration of hydrosalpinx should be performed prior to transplantation.

The present study explored the mechanism of Fagopyri Dibotryis Rhizoma(FDR) and its main active components in the treatment of acute lung injury(ALI) based on the network pharmacology and the in vitro experiments. The main active components of FDR were obtained from the TCMSP database and screened by oral bioavailability and drug-likeness. The related target proteins of FDR were retrieved from the PubChem database, and the target genes related to ALI were screened out from the GeneCards database. A protein-protein interaction(PPI) network of compound target proteins and ALI target genes was constructed using STRING 11.0. Ingenuity Pathway Analysis(IPA) platform was used to analyze the common pathways of the potential compound target proteins of FDR and ALI target genes, thereby predicting the key targets and potential signaling pathways of FDR for the treatment of ALI. Finally, the potential pathways and key targets were verified by the in vitro experiments of lipopolysaccharide-induced RAW264.7 cells intervened by epicatechin(EC), the active component of FDR. The results of network pharmacology showed that 15 potential active components such as EC, procyanidin B1, and luteolin presumedly functioned in the treatment of ALI through nuclear transcription factor-κB(NF-κB) signaling pathway, transforming growth factor-β(TGF-β) signaling pathway, and adenosine 5'-monophosphate(AMP)-activated protein kinase(AMPK) signaling pathway through key targets, such as RELA(P65). The results of in vitro experiments showed that 25 μmol·L~(-1) EC had no toxicity to cells and could inhibit the expression of the p65-phosphorylated protein in the NF-κB signaling pathway to down-regulate the expression of downstream inflammatory cytokines, including tumor necrosis factor-α(TNF-α), IL-1β and nitric oxide(NO), and up-regulate the expression of IL-10. These results suggested that the therapeutic efficacy of FDR on ALI was achieved by inhibiting the phosphorylation of p65 protein in the NF-κB signaling pathway and down-regulating the level of proinflammatory cytokines downstream of the signaling pathways.

Objective:To investigate the inhibitory effects and mechanism of Reyanning mixture （RYN） combined with linezolid （LNZ） against methicillin-resistant Staphylococcus aureus （MRSA） and its biofilm. Method:The minimum inhibitory concentrations （MICs） of RYN and LNZ against MRSA were determined by microdilution assay. The microplate method was used to detect the changes in viable count before and after MRSA administration at four time points （0， 6， 12， 24 h） in the process of biofilm growth. The morphological changes of MRSA after 24 h were observed by scanning electron microscope. Metabonomic technique was applied to analyze the changes in terminal metabolites of endogenous small molecules from MRSA treated by the two drugs at four time points. Result:The MICs of RYN and LNZ were 1/2 of the stock solution concentration and 4 mg·L^-1， respectively. The inhibitory effect of LNZ （2 mg·L^-1） against viable bacteria at 0 h was better than that of 1/16 RYN. At 6， 12， 24 h， 1/16 RYN was superior to LNZ in inhibiting MRSA. The inhibitory effects of RYN combined with LNZ were better than those of RYN or LNZ alone at the four time points. RYN combined with LNZ caused more severe damages to the morphological structure of MRSA biofilm at 24 h than RYN or LNZ alone. Cyclic adenosine monophosphate （cAMP）， adenosine diphosphate （ADP）-D-ribose and 2-methylbutanoyl-coenzyme A （2M-CoA）， as the metabolites related to biofilm formation， were immune to LNZ， but 2M-CoA and ADP-D-ribose were influenced by RYN at 12 h and 24 h. The combined use of RYN and LNZ interfered with the three metabolites at 24 h. L-tryptophan， phenylpyruvic acid， cytidine and sebacic acid were the pharmacometabolic markers of LNZ， and the related biological pathways were phenylalanine， tyrosine and tryptophan biosynthesis and phenylalanine metabolism. Four metabolites such as L-histidine， uric acid， and L-lysine were the pharmacometabolic markers of RYN， with phenylalanine metabolism and aminoacyl-transfer ribonucleic acid （tRNA） biosynthesis confirmed as the related biological pathways. Nine metabolites such as L-tryptophan， L-lysine， and sphingosine-1-phosphate were responsible for the efficacy of RYN combined with LNZ. The related biological pathways involved aminoacyl-tRNA biosynthesis， phenylalanine， tyrosine and tryptophan biosynthesis， novobiocin biosynthesis， and tyrosine metabolism. Conclusion:RYN combined with LNZ better exerts the inhibitory effects against MRSA at each time point of its biofilm formation， which is attributed to cAMP metabolism. The synergistic effect resulted from aminoacyl-tRNA biosynthesis and phenylalanine， tyrosine and tryptophan biosynthesis. RYN combined with LNZ can serve as a potentially effective solution to MRSA infection.
