Background: Increasing evidence has shown that visit-to-visit variability (VVV) of blood pressure (BP) is associated with an increased risk of cardiovascular disease (CVD). The objective of this study was to evaluate the impact of VVV of systolic blood pressure (SBP) and diastolic blood pressure (DBP) on the risk of CVD among patients with type 2 diabetes mellitus (T2DM) in China. Methods: We conducted a retrospective cohort study of 10,163 T2DM patients who were not previously diagnosed with CVD from January 2008 to December 2012 in Ningbo, China. The VVV of BP was calculated using five metrics, including standard deviation (SD), coefficient of variation (CV), variation independent of mean, average real variability, and successive variability (SV) of measurements, obtained over a 24-month measurement period. Hazard ratios and 95% confidence intervals (CIs) were estimated by Cox proportional hazards regression models for the associations of variability in BP with risk of CVD. Results: A total of 894 CVD events were observed during a median follow-up of 49.5 months. The hazard ratio in the highest quintile of SD of SBP was 1.24 (95% CI, 1.01 to 1.52) compared with patients in the lowest quintile. The association between higher VVV of DBP and risk of CVD was not consistent across different metrics and sensitivity analyses. Conclusion: Higher VVV of SBP was associated with an increased risk of CVD, irrespective of the mean SBP level. Future studies are needed to confirm these findings.

Background Nisoldipine can effectively suppress pulmonary arterial smooth muscle cell proliferation and c-Fos expression. Objective To identify the mechanism of the anti-inflammatory effects in monocrotaline-induced pulmonary arterial hypertension (PAH), focusing on the c-Fos/NLRP3/caspase-1 pathway. Results In a mice model of monocrotaline-induced PAH, miRNA-155 expression was increased. In an in vitro model, overexpression of miRNA-155 promoted inflammation and induced c-Fos, NLRP3, and caspase-1 protein expression. The inhibition of c-Fos reduced the effects of miRNA-155 on inflammation in an in vitro model of monocrotaline-induced PAH. The inhibition of NLRP3 reduced the effects of miRNA-155 on inflammation in an in vitro model of monocrotaline-induced PAH. Conclusions miRNA-155 increased inflammation in monocrotaline-induced PAH through c-Fos/NLRP3/caspase-1.
