Expression of heme oxygenase-1 in type II pneumocytes protects against heatstroke-induced lung damage.

Heatstroke (HS) is an acute clinical disease characterized by abnormal hyperthermia and multi-organ dysfunction. Heme oxygenase (HO)-1, also called heat shock protein (HSP)32, is induced by hyperthermia and also plays protective roles in many lung disease models. Based on this phenomenon, we investigated the protective role of endogenous HO-1 in heat-induced lung damage in rats.

Transradial versus transfemoral rotablation for heavily calcified coronary lesions in contemporary drug-eluting stent era.

Background: Although radial access for drug-eluting stent (DES) combined with rotational atherectomy (RA) in patients with calcified coronary lesions may be associated with a lower risk of major bleeding complications and obtain favorable clinical results compared with femoral access, the long-term outcome data of this approach were limited in contemporary DES era.

Methods & Results: This retrospective study sought to compare in-hospital and long-term outcomes for patients undergoing RA via the transradial (TR) and transfemoral (TF) route in 126 consecutive patients (59 radial, 67 femoral) from 2009 to 2014. TR RA procedures were performed in 44/62 (71%) by the three TR operators, compared with 15/64 (23%) by the four TF operators in the present study.
