Relationship between expression of chemokine receptors CCR3, CCR5 and CXCR3 on CD4(+) T cells and spontaneous abortion in mice.
Previous studies have shown that local immune cells in the feto-maternal interface are recruited from peripheral blood, and that chemokines and their receptors play an initial and key role in this recruitment process. In this study, we aimed to determine whether spontaneous abortion is associated with the expression of chemokine receptors CCR3, CCR5, and CXCR3 on CD4(+) T cells. ⋯ The abnormal expression of CCR3, CCR5 and CXCR3 on CD4(+) T cells may play an important role in the pathogenesis of spontaneous abortion.

Mutation of plakophilin-2 gene in arrhythmogenic right ventricular cardiomyopathy.
Arrhythmogenic right ventricular cardiomyopathy (ARVC) is one of the leading causes of sudden cardiac death. Recent studies have shown that ARVC, which is an inheritable genetic change, results from mutations in genes encoding desmosomal proteins. Plakophilin-2 is an important component of the desmosome. Because the full range of genetic variations related to ARVC is unknown and no related studies of the Chinese population have been reported, we aimed to investigate the genetic variation of plakophilin-2 in ARVC patients from the Southern Region of China. ⋯ We discovered a plakophilin-2 mutation that prolongs the QT interval dispersion in the southern Chinese ARVC population.

GATA4 and NKX2.5 gene analysis in Chinese Uygur patients with congenital heart disease.
Congenital heart disease (CHD) is the most common developmental anomaly in newborns. The germline mutations in GATA4 and NKX2.5 genes have been identified as responsible for CHD. The frequency of GATA4 and NKX2.5 mutations in Chinese Uygur patients with CHD and the correlation between their genotype and CHD phenotype are unknown. ⋯ Our results provided the primary data on CHD phenotype associated with GATA4 mutation in the Chinese Uygur population.

Effects of ketamine and midazolam on morphology of dendritic spines in hippocampal CA1 region of neonatal mice.
It is a common phenomenon that children experience multiple general anesthesias in clinical practice, which raises the question whether repeated exposure to general anesthetics would interfere with the development of the central nervous system of children. The present study was designed to evaluate the effects of repeated treatment with ketamine or midazolam on postnatal dendrite development by examining the morphology of the dendritic spines of the pyramidal neurons in the hippocampal CA1 region in mice. ⋯ This study indicated that repeated exposure to ketamine or midazolam in neonatal mice impaired dendritic spine maturation immediately afterwards, but this influence seemed to disappear during further postnatal development.

Effect of coronary bifurcation angle on clinical outcomes in Chinese patients treated with crush stenting: a subgroup analysis from DKCRUSH-1 bifurcation study.
Bifurcation angles may have an impact on the clinical outcomes of crush stenting. We sought to compare high (> or = 60 degrees ) with low (< 60 degrees ) bifurcation angle in patients who underwent either classical or double kissing (DK) crush stenting for bifurcation lesions from the DKCRUSH-1 data base. ⋯ Bifurcation angles do not influence the clinical outcome of crush stenting. Successful final kissing balloon inflation, regardless of bifurcation angles, can predict TLR.
