Mast cells are (in)famous for their role in allergic diseases, but the physiological and pathophysiological roles of this ingenious cell are still not fully understood. Mast cells are important for homeostasis and surveillance of the human system, recognizing both endogenous and exogenous agents, which induce release of a variety of mediators acting on both immune and non-immune cells, including nerve cells, fibroblasts, endothelial cells, smooth muscle cells, and epithelial cells. During recent years, clinical and experimental studies on human mast cells, as well as experiments using animal models, have resulted in many discoveries that help decipher the function of mast cells in health and disease. In this review, we focus particularly on new insights into mast cell biology, with a focus on mast cell development, recruitment, heterogeneity, and reactivity. We also highlight the development in our understanding of mast cell-driven diseases and discuss the development of novel strategies to treat such conditions. 相似文献

BackgroundPercutaneous coronary intervention (PCI) of total chronic total occlusion (CTO) still remains a major challenge in interventional cardiology. There is only insignificant knowledge reported in the literature about the influence of body mass index (BMI) on acute outcome, including success rates and complications in CTO-PCI.MethodsBetween 2012 and 2017, we included 508 patients. They underwent PCI for at least one CTO. Antegrade and retrograde CTO techniques were applied. The retrograde approach was used only after failed antegrade intervention. BMI was calculated according to the definitions of the World Health Organization. It was subdivided as normal weight (18.5–24.9 kg/m2), overweight (25–29.9 kg/m2), obese (30–34.9 kg/m2), and very obese (≥35 kg/m2). The Shapiro–Wilk test was used to test for normality of distribution. Continuous variables were tested for differences with Kruskal–Wallis or Mann–Whitney U test as appropriate. Categorical variables were tested with Fisher exact test.ResultsOut of the 508 patients, 77 (15.2%) had normal weight, 286 (56.3%) were overweight, 106 (20.9%) obese, and 39 (7.7%) very obese. Radiation dose and examination time increased with elevated BMI categories (p < 0.001, p = 0.026). Success rates were similar in all BMI categories (p = 0.645). In-hospital procedural complications were rare and showed no statistically significant difference (p = 0.185).ConclusionsOur retrospective study suggests that there exists no significant association between overweight and acute outcome in patients undergoing CTO-PCI. It is safe and feasible to perform. 相似文献
