Effects of renal denervation on cardiac function after percutaneous coronary intervention in patients with acute myocardial infarction.

Objective: To observe the effect of renal artery denervation (RDN) on cardiac function in patients with acute myocardial infarction after percutaneous coronary intervention (AMI-PCI).

Methods: This is a single-centre, prospective randomized controlled study. A total of 108 AMI-PCI patients were randomly assigned to the RDN group or the control group at 1:1 ratio.

Effects of renal denervation therapy on cardiac function and malignant arrhythmia in patients with reduced left ventricular ejection fraction and narrow QRS complexes treated with implantable cardioverter defibrillator.

The purpose of this study was to explore the effects of renal denervation (RDN) on cardiac function and malignant arrhythmia in patients with reduced left ventricular ejection fraction (HFrEF) and narrow QRS treated with an implantable cardioverter defibrillator (ICD). A total of 20 eligible HFrEF patients [left ventricular ejection fraction (LVEF) <40%] and narrow QRS complexes (QRS duration <120 ms) were randomized into either the ICD plus RDN group or the ICD only group during 17 April 2014 to 22 November 2016. Clinical data, including clinical characteristics, blood biochemistry, B-type natriuretic peptide, echocardiographic indexes, 6-min walk distance (6MWD), New York Heart Association (NYHA) classification, and count of ICD discharge events before and after the operation were analyzed.

[Study of chigger communities on major species of rodents in Yunnan Province].

Objective: To understand the characteristics of the chigger communities on the major species of rodent hosts.

Methods: Rats were captured in 16 counties (or towns) of Yunnan. All the mites on the two auricles of the host were collected and identified.

[Investigation of chigger mites on the rat Eothenomys miletus in Yunnan].

Objective: To understand the species, species distribution, the dominant species and their interspecies interaction of chigger mites on Eothenomys miletus(a dominant species of rats) in Yunnan.

Method: The rats were captured with mouse traps in 16 counties (or cities) during 2000-2004. All mites on the surface of two auricles of the hosts were collected and identified.
