Objective:To explore the association between cumulative blood pressure (BP) and the risk of cerebrovascular disease (CVD) in older adults.Methods:This retrospective cohort study consecutively selected 4 480 older adults who participated in the Chinese Longitudinal Healthy Longevity Survey from 2008 to 2009 as the study subjects. The cumulative BP was calculated using the area under the curve from measurements taken at baseline (2008-2009), the first follow-up (2011), and the second follow-up (2014). The subjects were grouped with the quartiles (Q1-Q4) of cumulative systolic blood pressure (SBP), diastolic blood pressure (DBP), and pulse pressure (PP). The Cox proportional hazards regression models were used to analyze the hazard ratios (HR) and 95% CI for the association between cumulative BP and the risk of CVD among older adults. The restricted cubic spline function was employed to examine the potential dose-response pattern between cumulative BP and the risk of CVD. Results:During a total of 40 230 person-years of follow-up, with a mean follow-up duration of (8.98±2.16) years, 768 new cases of CVD were identified. The older adults in the highest quartile (Q4) of cumulative SBP, DBP, and PP had a significantly higher risk of CVD compared to those in the lowest quartile (Q1), with a HR of 1.68 (95% CI: 1.36-2.06), 1.67 (95% CI: 1.36-2.06), and 1.52 (95% CI: 1.24-1.84), respectively (all P<0.001). For every 10 mmHg (1 mmHg=0.133 kPa)×year increase in cumulative SBP, DBP, and PP, the risk of CVD increased by 2% ( HR=1.02, 95% CI: 1.01-1.03), 3% ( HR=1.03, 95% CI: 1.01-1.05), and 2% ( HR=1.02, 95% CI: 1.01-1.03), respectively (all P<0.05). The restricted cubic spline model revealed a linear positive correlation between cumulative SBP, DBP, and PP with the risk of CVD among older adults (all P for nonlinearity>0.05). When cumulative SBP, DBP, and PP exceeded 791.9 mmHg×years, 462.9 mmHg×years, and 323.6 mmHg×years, corresponding to an average BP level of 132.0 mmHg, 77.2 mmHg, and 53.9 mmHg, respectively, the risk of CVD began to increase. Conclusions:Elevated long-term cumulative BP may increase the risk of CVD in older adults. Caution is warranted when SBP, DBP, and PP exceed 132.0 mmHg, 77.2 mmHg, and 53.9 mmHg, respectively.

Angiogenesis within atherosclerotic plaques is a critical determinant of plaque stability.The biome-chanical microenvironment,consisting of fluid shear force,plaque structural stress,and matrix stiffness,serves as signifi-cant factors in mediating plaque angiogenesis.Endothelial cells respond to mechanical signals and participate in plaques neovascularization through force chemical signal transduction mechanisms.This review provides an overview of the mecha-nisms by which mechanical factors regulate angiogenesis within plaques and offers a novel therapeutic approach for the pre-vention and treatment of atherosclerosis.

Objective To investigate the relationship between daily intake of B vitamins(vitamins Bl,B2,B6 and niacin)and chronic constipation and chronic diarrhea.Methods Data of 3 durations(2005-2006,2007-2008 and 2009-2010)from National Health and Nutrition Examination Survey(NHANES)database were collected and retrospectively analyzed.For the 13 788 participants,their intake of vitamin B1,B2,B6,and niacin were assessed through a 24-hour dietary recall interview.Multivariate logistic regression analysis was employed to explore the correlation between B vitamins and chronic constipation and chronic diarrhea.Additionally,sensitivity analysis and curve fitting correlation analysis were conducted to further elucidate the observed relationships.Results Among the subjects who were enrolled in the study,2 520(18.28％)were diagnosed with chronic constipation,while 2 138(15.51％)were diagnosed with chronic diarrhea.Multivariate logistic regression analysis and sensitivity analysis indicated linear correlations between the intake of vitamin B1,niacin and vitamin B6 and the occurrence of chronic constipation and chronic diarrhea.An increase in the daily intake of these nutrients potentially reduced the risk of chronic constipation,but also increased the risk of chronic diarrhea(P＜0.05).Conclusion Daily intake of vitamins B1,B2,B6 and niacin is correlated with the occurrence of chronic constipation and chronic diarrhea.

c-Myc protein encoded by c-Myc (cellular-myelocytomatosis viral oncogene) gene regulates the related gene expression through the Wnt/β-catenin signaling pathway, and has received extensive attention in recent years. The purpose of this study was to express Helicoverpa armigera c-Myc gene (Ha-c-Myc) by using prokaryotic expression system, prepare the polyclonal antibody, examine the spatio-temporal expression profile of Ha-c-Myc, and investigate the possible function of Ha-c-Myc in regulating H. armigera sterol carrier protein-2 (SCP-2) gene expression. The Ha-c-Myc gene was amplified by PCR and cloned into a prokaryotic expression plasmid pET-32a(+). The recombinant plasmid pET-32a-Ha-c-Myc was transformed into Escherichia coli BL21. IPTG was used to induce the expression of the recombinant protein. Protein was purified by Ni²⁺-NTA column and used to immunize New Zealand rabbits for preparing the polyclonal antibody. The Ha-c-Myc expression levels in different developmental stages (egg, larva, prepupa, pupa, and adult) of H. armigera and different tissues (midgut, fat body, head, and epidermis) of the prepupa were determined by real-time quantitative reverse transcription PCR (qRT-PCR). Ha-c-Myc siRNA was synthesized and transfected into H. armigera Ha cells. The relative mRNA levels of Ha-c-Myc and HaSCP-2 in Ha cells were detected by qRT-PCR. Results showed that the pET-32a-Ha-c-Myc recombinant plasmid was constructed. The soluble Ha-c-Myc protein of about 65 kDa was expressed in E. coli. The polyclonal antibody was prepared. Western blotting analysis suggested that the antibody had high specificity. Enzyme linked immunosorbent assay (ELISA) showed that the titer of the antibody was high. Ha-c-Myc gene expressed at all developmental stages, with high levels in the early and late instars of larva, and the prepupal stage. Tissue expression profiles revealed that Ha-c-Myc expressed in various tissues of prepupa, with high expression level in the midgut, but low levels in the epidermis and fat body. RNAi results showed that the knockdown of Ha-c-Myc expression significantly affected transcription of HaSCP-2, leading to a 50% reduction in HaSCP-2 mRNA expression level. In conclusion, the Ha-c-Myc was expressed through a prokaryotic expression system, and the polyclonal anti-Ha-c-Myc antibody was obtained. Ha-c-Myc may promote the expression of HaSCP-2 and play an important role in the lipid metabolism of H. armigera. These results may facilitate further study on the potential role and function mechanism of Ha-c-Myc in H. armigera and provide experimental data for exploring new targets of green pesticides.

Insomnia, as the most common sleep disorder in the population, is often accompanied by depression, anxiety and other mental diseases, which can lead to impaired social and occupational functions as well as decreased quality of life. There is growing evidence that insomnia may be a risk factor for stroke. On the other hand, the incidence of insomnia in stroke patients is significantly higher than that in the general population. Correctly understanding the bidirectional relationship between insomnia and stroke can make clinicians pay more attention to insomnia and its treatment, and increase clinical benefit in patients with stroke and insomnia.
