ABSTRACT
BACKGROUND@#The prevalence of hypertension is high among Chinese adults, thus, identifying non-hypertensive individuals at high risk for intervention will help to improve the efficiency of primary prevention strategies.@*METHODS@#The cross-sectional data on 9699 participants aged 20 to 80 years were collected from the China National Health Survey in Gansu and Hebei provinces in 2016 to 2017, and they were nonrandomly split into the training set and validation set based on location. Multivariable logistic regression analysis was performed to develop the diagnostic prediction model, which was presented as a nomogram and a website with risk classification. Predictive performances of the model were evaluated using discrimination and calibration, and were further compared with a previously published model. Decision curve analysis was used to calculate the standardized net benefit for assessing the clinical usefulness of the model.@*RESULTS@#The Lasso regression analysis identified the significant predictors of hypertension in the training set, and a diagnostic model was developed using logistic regression. A nomogram with risk classification was constructed to visualize the model, and a website ( https://chris-yu.shinyapps.io/hypertension_risk_prediction/ ) was developed to calculate the exact probabilities of hypertension. The model showed good discrimination and calibration, with the C-index of 0.789 (95% confidence interval [CI]: 0.768, 0.810) through internal validation and 0.829 (95% CI: 0.816, 0.842) through external validation. Decision curve analysis demonstrated that the model was clinically useful. The model had a higher area under receiver operating characteristic curves in training and validation sets compared with a previously published diagnostic model based on Northern China population.@*CONCLUSION@#This study developed and validated a diagnostic model for hypertension prediction in Gansu Province. A nomogram and a website were developed to make the model conveniently used to facilitate the individualized prediction of hypertension in the general population of Han and Yugur.

A large number of data show that the prevalence rate of alcoholic liver injury （ALI） is increasing year by year， and it has become one of the main causes of death due to chronic liver diseases such as liver cancer and liver cirrhosis. Quitting drinking is the main method for the prevention of ALI in modern medicine， and the main treatment methods include Western medicine with antioxidant and anti－fibrotic effects and nutritional support. However， Western medicine tends to have an unsatisfactory treatment effect and can only alleviate initial symptoms， and severe ALI still requires surgical treatment. Studies have shown that the monomers extracted from natural drugs and foods have obvious preventive and therapeutic effects on ALI， with high safety and easy access. Therefore， this article systematically summarizes the main natural drug and food monomers used for the prevention and treatment of ALI and proposes the idea of the combination of drug and food for the prevention and treatment of ALI from the perspective of paying attention to the whole process of health， in order to explore more effective prevention， health care， and treatment methods and provide ideas for research on the prevention and control of ALI.
ABSTRACT
Objective:To establish the reference for serum metabolomics profiles among healthy Han adults in China, and explore the variation on metabolomics profiles by geographic regions, sex, and age.Methods:Cross-sectional data and serum samples were obtained from the China National Health Survey. A total of 1 039 male and 1 032 female healthy adults(≥30 years) were included in this study. Serum metabolomics analyses were conducted with ultra-performance liquid chromatography-mass spectrometry(UPLC-MS). Orthogonal partial least squares discriminant analysis(OPLS-DA) was performed to compare the differences of metabolomics among different region, sex, and age.Results:Significant differences on metabolomics profiles were identified among region, sex, and age. A total of 114 region-related metabolites were spotted, including 53 metabolites that involved in human metabolic pathways, mainly peptides(20 metabolites) and glycerophospholipid metabolism-related(14 metabolites). Fifty-nine metabolites were pinned down to be sex-related, among which cotinine was significant in all 7 provinces. Age-related metabolites were only found in Shaanxi and Hainan, with 22 metabolites were recognized.Conclusion:Serum metabolomics varies by geographic regions, sex, and age. When metabolomics is applied for diagnosis or biomarker screening in various studies, it shall take into consideration of setting tailored references.
ABSTRACT
Objective To study the effect of rosuvastatin(RSVT) on the vascular endothelial function(VEF) ,inflammatory fac‐tors(IF) and prognosis in patients with acute coronary syndrome (ACS) after percutaneous coronary intervention(PCI) .Methods Eighty cases of ACS patients with PCI in our hospital selected from July 2010 to July 2013 were randomly divided into observed group and control group ,40 cases in each group .The observation group were given interference treatment with RSVT while the control group received conventional treatment .The VEF ,IF and prognosis were compared between groups .Results The VWF at 4 weeks after PCI in observation group was lower than that in control group [(92 .6 ± 12 .3)% vs .(105 .4 ± 13 .6)% ,P<0 .05];The ET‐1 at 4 weeks after PCI in observation group was lower than that in control group[(55 .6 ± 5 .6)ng/L vs .(67 .8 ± 7 .4)ng/L ,P<0 .05] .The NO at 4 weeks after PCI in observation group was higher than that of control group[(78 .6 ± 9 .4)μmol/L vs .(63 .2 ± 9 .5)μmol/L ,P<0 .05] .The CRP at 4 weeks after PCI in observation group was lower than that in control group[(5 .4 ± 2 .2) mg/L vs .(10 .5 ± 4 .1)mg/L ,P<0 .05] .The incidence of CVE was 5 .00% (2/40) ,restenosis rate was 2 .50% (1/40) in observa‐tion group ,which was significantly lower than those of the control group [30 .00% (12/40) ,10 .00% (4/40)] ,the differences were statistically significant(P<0 .05) .Conclusion RSVT could effectively improve the VEF and reduce inflammation ,CVE and rest‐enosis rate in patients with ACS after PCI .
ABSTRACT
AIM:To observe the effect of Wnt/β-catenin signaling pathway on diabetic ulcer.METHODS:Diabetic animal model was established in the female Wistar rats by intraperitoneal injection of low-dose streptozotocin fol-lowing high-fat diet feeding.A circular wound was made on the dorsum of the rats in both control group and diabetic group. The condition of wound healing was recorded and the structures of the wound tissues were observed by HE staining in the 2 groups at 3, 7 and 14 d after wounding.The expression ofβ-catenin, GSK-3βand Rspo-3 at mRNA and protein levels in the wound tissues was detected by RT-PCR and ELISA.RESULTS:In diabetic group, the wound healing rate was lower (P<0.05), and the inflammatory cells, fibroblast cells and new capillaries in the wound tissues were fewer than those in control group.The expression of β-catenin and Rspo-3 at mRNA and protein levels in the wound tissues in control group was significantly higher than those in diabetic group, and the expression of GSK-3βwas exactly the opposite (P<0.05). CONCLUSION:The down-regulation of Wnt/β-catenin probably resultes from the decreased level of Rspo-3, which may be one of the reasons for delaying the diabetic ulcer healing.
ABSTRACT
The Many experiments show that pH affect the growth of romastigotes of L donovani. But the control tests with Acid - base scale have not been reported on the growth of promastigotes from different genesis. This paper reports that pH has different nfluence on several kinds of promastigotes from different genesis. We obseved that the growth of promastigotes of L. doncvani is inhibited when pH is 4.6 and 8.6.
