Abstract To illuminate changes in the secondary metabolic spectrum and hypoglycemic activity between Rose roxburghii fruit fermented (RRFF) by Chinese traditional distiller’s yeast and R. roxburghii fruit (RRF) using UPLC–MS/MS and streptozotocin-induced diabetic mice. Secondary metabolomics in the RRFF apparently differs from those in RRF; 32 pentacyclic triterpenoids were identified first, and ursolic acid-substituted roxburix acids were found to be the marker compounds. Testing of HepG2 cells indicated that RRFF had good glucose consumption capacity. Additionally, fasting blood glucose levels, glucose tolerance tests, plasma insulin levels and insulin resistance in diabetic mice indicated that RRFF was better than RRF. More importantly, RRFF exhibited good structure in pancreatic tissue. These results indicate that the fermentation process is beneficial for increasing the content of triterpenoids and enhancing hypoglycemic activity. Traditional fermentation with Chinese traditional distiller’s yeast can provide a way to expand the application of nutritious fruits with short shelf life.

ABSTRACT OBJECTIVE To evaluate the relationship between ambient air pollutants and chronic obstructive pulmonary disease in relatively low-polluted areas in China. METHODS Atmospheric pollutants levels and meteorological data were obtained from January 2016 to December 2020. The medical database including daily hospital admissions for chronic obstructive pulmonary disease (ICD10: J44) was derived from the First Affiliated Hospital of Gannan Medical University. The generalized additive model was used to analyze the percentage change with 95% confidence interval in daily hospital admissions for chronic obstructive pulmonary disease associated with a 10 µg/m3 increase in atmospheric pollutants levels. RESULTS In total, occurred 4,980 chronic obstructive pulmonary disease hospital admissions (not including emergency department visits) during 2016–2020. The mean concentrations of daily PM2.5, PM10, SO2, NO2, O3, and CO were 37.5 μg/m3, 60.1 μg/m3, 18.7 μg/m3, 23.5 μg/m3, 70.0 μg/m3, and 1.2 mg/m3 in Ganzhou. Each 10 µg/m3 increment of PM2.5, PM10, NO2, and O3 were significantly associated with 2.8% (95%CI: 1.0–4.7), 1.3% (95%CI: 0.3–2.4), 2.8% (95%CI: 0.4–5.4), and 1.5% (95%CI: 0.2–2.7) elevation in daily chronic obstructive pulmonary disease hospital admissions. The estimates of delayed effects of PM2.5, PM10, NO2, and O3 were observed at lag6, lag6, lag8, lag1, respectively. The health effects of particulate pollutants (PM2.5 and PM10) may be independent of other pollutants. The adverse effects of air pollutants were more evident in the warm season (May–Oct) than in the cold season (Nov–Apr). CONCLUSION Our study demonstrated that elevated concentrations of atmospheric pollutant (PM2.5, PM10, NO2, and O3), especially particulate pollutants, can be associated with increased daily count of hospital admissions for chronic obstructive pulmonary disease , which may promote further understanding of the potential hazards of relatively low levels of air pollution on chronic obstructive pulmonary disease and other respiratory disorders.

Resumo Fundamento: Há poucos dados referentes às disparidades no manejo de fatores de risco cardiovascular entre pacientes tratados com intervenção coronária percutânea (ICP) e aqueles tratados com cirurgia de revascularização miocárdica (CRM). Objetivo: Avaliar se as taxas de cumprimento de metas de fatores de risco cardiovascular diferiram entre pacientes submetidos a ICP ou a CRM. Métodos: Revisão retrospectiva de banco de dados de prontuários médicos de pacientes admitidos no Hospital Beijing Anzhen entre 1 de janeiro de 2014 e 31 de dezembro de 2014, submetidos a ICP ou a CRM. Resultados: Comparado ao grupo CRM, o grupo ICP apresentou taxas significativamente maiores de cumprimento de meta de colesterol da lipoproteína de baixa densidade (LDL-C) < 1,8 mmol/L (28,6% vs. 24,7%; p < 0,01), LDL-C < 2,07 mmol/L (43,5% vs. 39,4%; p < 0,01) e pressão arterial (PA) <140/90 mmHg (85,6% vs. 77,7%; p < 0,01). Comparados aos pacientes ≥ 60 anos de idade, aqueles < 60 anos de idade apresentaram melhor taxa de cumprimento de meta de PA < 140/90 mmHg (87,7% vs. 84,4%; p < 0,01) no grupo ICP, e melhores taxas de cumprimento de meta de glicemia de jejum (GJ) < 7 mmol/L (79.4% vs.72.0%; p < 0.01) e HbA1c < 7% (79.4% vs. 70.1%; p < 0.01) no grupo CRM. Comparados às mulheres, os homens apresentaram melhores taxas de cumprimento de meta de LDL-C < 2,07 mmol/L (24,7% vs. 28,5%; p < 0,01), GJ < 7 mmol/L (71,8% vs. 75,2%; p < 0,01) e HbA1c < 7% (70,4% vs. 74,1%; p < 0,01) no grupo ICP. Conclusão: Em geral, o grupo ICP apresentou maior probabilidade do que o grupo CRM de cumprir as metas de LDL-C < 1,8 mmol/L e PA. O controle dos fatores de risco cardiovascular diferiu entre pacientes ≥ 60 e < 60 anos de idade. As mulheres apresentaram menor probabilidade de cumprir as metas de LDL-C, GJ e HbA1c.

Abstract Background: Data are scarce regarding disparities in cardiovascular risk factor management between patients treated with percutaneous coronary intervention (PCI) and those treated with coronary artery bypass grafting (CABG). Objective: Whether the goal achievement rates of cardiovascular risk factors were different between PCI and CABG patients. Methods: We retrospectively reviewed the data retrieved from a clinical record database of patients admitted to Beijing Anzhen Hospital between January 1, 2014, and December 31, 2014, who underwent PCI or CABG. Results: Compared with the CABG group, low-density lipoprotein cholesterol (LDL-C) < 1.8 mmol/L (28.6% vs. 24.7%; p < 0.01), LDL-C < 2.07 mmol/L (43.5% vs. 39.4%; p < 0.01) and blood pressure (BP) < 140/90 mm Hg (85.6% vs. 77.7%; p < 0.01) goal achievement rates were significantly higher in the PCI group. Compared with patients ≥ 60 years old: patients < 60 years old had better BP < 140/90 mm Hg goal achievement rates (87.7% vs. 84.4%; p < 0.01) in the PCI group, and better fasting blood-glucose (FBG) < 7 mmol/L (79.4% vs.72.0%; p < 0.01) and HbA1c < 7% (79.4% vs. 70.1%; p < 0.01) goal achievement rates in the CABG group. Compared with females: males had better LDL-C < 2.07 mmol/L (24.7% vs. 28.5%; p < 0.01), FBG < 7 mmol/L (71.8% vs.75.2%; p < 0.01) and HbA1c < 7% (70.4% vs. 74.1%; p < 0.01) goal achievement rates in the PCI group. Conclusion: Patients in the PCI group were generally more likely than those in the CABG group to achieve LDL-C < 1.8 mmol/L and BP goals. The control of cardiovascular risk factors differed between patients ≥ 60 years old and < 60 years old. Female patients were less likely to achieve LDL-C, FBG and HbA1c goals.

Electrosynthesis of dimethyl carbonate (DMC) from methanol and carbon monoxide using an Cu(phen)Cl2 catalyst was achieved at room temperature and atmospheric pressure. The catalytic activity of the ligand 1,10-phenanthroline (phen) and the catalytic system were analyzed. The IR characterization results for the complex catalyst showed that copper ions were coordinated by nitrogen atoms of phen. In addition, the effects of the influencing factors, such as reaction time (t), reaction temperature (T) and the surface area of the working electrode (SWE) were studied.
