Objective:
To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD.
Methods:
Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model.
Results:
A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966).
Conclusion
The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.

Objective:To improve the prognosis stratification, especially early mortality(EM), of elderly patients with newly diagnosed multiple myeloma(NDMM).Methods:In this retrospective study, univariate and multivariate Cox regression analysis were conducted to identify the independent prognostic factors associated with overall survival(OS)and the chi-square test and multivariate Logistic analysis were used to identify the prognostic factors associated with EM in 223 elderly patients(age≥65 years)with NDMM from three centers in the country.Results:Increased NT-pro-BNP(≥300 pg/ml), ECOG-PS≥2 and stage Ⅲ R-ISS were identified as three independent adverse prognostic factors of OS.The rates of EM3, EM6, EM12 and EM24 were 12.1%, 20.1%, 32.2% and 60%, respectively.The most common cause for EM6(particularly EM3)was disease-related complications resulting from ineligibility for treatment due to poor physical performance, severe organ dysfunction or treatment discontinuation due to treatment intolerance, while the most common cause for EM12(particularly EM24)was disease progression or relapse mainly as a result of inadequate treatment.R-ISS staging failed to predict EM, while decreased eGFR, ECOG-PS≥2, and increased NT-pro-BNP were able to estimate the risk of EM, with increased NT-pro-BNP as a common independent factor for EM12( P=0.03)and EM24( P=0.015). Conclusions:R-ISS staging, which primarily reflects MM biology, cannot predict EM.However, factors such as NT-pro-BNP, eGFR and ECOG-PS associated with frailty and impairment of organ functions can be used to estimate the risk of EM, among which NT-pro-BNP may be the most important independent factor for EM.Therefore, incorporation of these frailty-related biomarkers into R-ISS staging may be able to more precisely estimate the prognosis and particularly early death of elderly patients with NDMM.

ObjectiveBased on non-targeted metabolomics, to analyze the regulation of endogenous differential metabolites in serum of type 2 diabetes mellitus(T2DM) rats by Fuling Yunhua granules, and to clarify the metabolic pathways through which this granules exerted its effect on improving T2DM. MethodSeventy SD rats, half male and half female, were randomly divided into the control group, model group, and high, medium, low dose groups of Fuling Yunhua granules(20.70, 10.35, 5.18 g·kg-1 in raw drug amount) and the positive drug group(pioglitazone hydrochloride tablets, 8.1 mg·kg-1). Except for the control group, other groups were fed with high-sugar and high-fat diet combined with intraperitoneal injection of streptozotocin(STZ) to establish a T2DM rat model. After successful modeling, the treatment groups were administered the corresponding drugs by gavage, and the control group and model group were treated with an equal volume of saline by gavage, once/d, for 28 d. Fasting blood glucose(FBG) and glycosylated hemoglobin A1c(GHbA1c) levels were measured in all groups of rats during the administration period, and hematoxylin-eosin(HE) staining was used to observe the pathomorphological changes in the pancreatic tissues of rats at the end of the administration period. The endogenous metabolite levels in rat serum were detected by ultra-performance liquid chromatography-linear ion trap-electrostatic field orbitrap high-resolution mass spectrometry(UPLC-LTQ-Orbitrap MS), and the data were processed using principal component analysis(PCA) and orthogonal partial least squares-discriminant analysis(OPLS-DA). Differential metabolites were identified by the Human Metabolome Database(HMDB) and the Kyoto Encyclopedia of Genes and Genomes(KEGG), and screened for differential metabolites with variable importance in the projection(VIP) value>1, P<0.05, and fold change(FC)<0.6 or FC>1. And the metabolic pathway enrichment analysis of the screened differential metabolites was performed by MetaboAnalyst 5.0, then the screened differential metabolites were diagnosed and evaluated by the receiver operating characteristic(ROC) curves. ResultCompared with the control group, the FBG level of rats in the model group increased significantly(P<0.01), the GHbA1c content tended to increase, but the difference was not statistically significant, and the pancreatic tissue of rats was obviously damaged, the number of pancreatic islets decreased, and the pancreatic β-cells were obviously reduced, atrophied and enlarged. Compared with the model group, the FBG levels of rats in the high dose group of Fuling Yunhua granules and the positive drug group were significantly reduced after 2 weeks of administration(P<0.05, P<0.01), the GHbA1c content of rats in the high dose group of Fuling Yunhua granules was significantly reduced(P<0.05), and the pancreatic tissue lesions of rats in the different dose groups of Fuling Yunhua granules were reduced. The results of non-targeted metabolomics showed that 46 differential metabolites were significantly changed in the model group compared with the blank group. Pathway enrichment analysis found that T2DM mainly affected biological processes including biosynthesis of primary bile acid, D-amino acid metabolism, steroid hormone biosynthesis, and glycerophospholipid metabolism in rats. Compared with the model group, the levels of 8 differential metabolites in the high dose group of Fuling Yunhua granules were significantly adjusted, and the pathway enrichment analysis found that D-amino acid metabolism, retinol metabolism, glycine, serine and threonine metabolism, tryptophan metabolism and other metabolic pathways were mainly involved. ROC curves further analysis revealed that the four characteristic differential markers of 11-cis-retinol, D-piperidinic acid, D-serine, and p-cresol sulfate had high diagnostic value for the treatment of T2DM with Fuling Yunhua granules. ConclusionFuling Yunhua granules can improve the symptoms of T2DM rats by regulating the amino acid metabolic and retinol metabolic pathways through the modulation of endogenous differential metabolites.

Idiopathic pulmonary fibrosis (IPF) is a progressive lung disease with unclear etiology and limited treatment options. The median survival time for IPF patients is approximately 2-3 years and there is no effective intervention to treat IPF other than lung transplantation. As important components of lung tissue, endothelial cells (ECs) are associated with pulmonary diseases. However, the role of endothelial dysfunction in pulmonary fibrosis (PF) is incompletely understood. Sphingosine-1-phosphate receptor 1 (S1PR1) is a G protein-coupled receptor highly expressed in lung ECs. Its expression is markedly reduced in patients with IPF. Herein, we generated an endothelial-conditional S1pr1 knockout mouse model which exhibited inflammation and fibrosis with or without bleomycin (BLM) challenge. Selective activation of S1PR1 with an S1PR1 agonist, IMMH002, exerted a potent therapeutic effect in mice with bleomycin-induced fibrosis by protecting the integrity of the endothelial barrier. These results suggest that S1PR1 might be a promising drug target for IPF therapy.
