INTRODUCTION Left ventricular (LV) dysfunction is common in septic shock. Its association with the clinical outcome is still controversial. Tissue Doppler imaging (TDI) is a useful tool to quantify LV function; however, little knowledge is available about the prognostic value of these TDI variables in septic shock. Therefore, we performed this prospective(More)
Our objective is to assess the incidence of cardiac and intraspinal abnormities in Chinese congenital scoliosis (CS) patients and to study the relationship between the associated abnormities and the different CS types. Five-hundred and thirty-nine consecutive Chinese patients with CS were retrospectively studied, and the records of echocardiography, plain(More)
OBJECTIVE The purpose of this study was to determine the values of the hemodynamic parameters of Doppler sonography in the diagnosis of renal artery stenosis (RAS) (diameter reduction >/=50%) and to investigate their possible influencing factors. METHODS Five Doppler parameters, including renal peak systolic velocity (RPSV), renal-aortic ratio (RAR),(More)
Pulmonary arterial hypertension (PAH) is a debilitating condition with progressive remodeling of the pulmonary resistance vessels. PAH is characterized by multifocal, polyclonal lesions inhabited by cells that underwent phenotypic transition, resulting in altered cell proliferation and contractility, ultimately resulting in increased vascular resistance.(More)
Hyperthyroidism is associated with many heart diseases. Thyrotoxic state has a relationship with coronary spasm. We present a case of a non-menopausal woman with hyperthyroidism who complained of chest pain. The diagnosis of coronary spasm was confirmed by coronary angiography (CAG). She is treated well with anti-thyrotoxicosis and anti-anginal medication.(More)
OBJECTIVE To compare clinical characteristics among premenopausal women with coronary arterial disease (CAD) with or without atherosclerosis (AS) and postmenopausal women with CAD. METHODS The clinical and coronary angiographic data, traditional risk factors (age, smoking, blood pressure, lipid profile, blood glucose, BMI, family history) were compared(More)
OBJECTIVE In order to understand the effects of cardiac microenvironment on the differentiation of bone marrow mesenchymal stem cells (MSCs) into myocardial-like cells, we simulated the cardiac microenvironment in vitro by adding myocardial cell lysate into the culture system of MSCs, and compared the differentiation promoting effect of myocardial cell(More)
OBJECTIVE To compare the in vivo immune reaction of transplanting porcine MSC-derived CLC with rabbit cardiomyocytes extracts induced differentiation or in vitro cultured porcine MSC. METHODS After injecting the MSC-derived CLC or MSC to the original porcines, the number of CD4+, CD8+ T cells were determined by flow cytometry. The serum concentrations of(More)
OBJECTIVE To compare the image quality and visibility of arteries of 64-slice spiral coronary CT angiography (CTA) with those of 16-slice spiral coronary CTA, and to evaluate the diagnostic accuracy of 64-slice spiral CT for the assessment of coronary artery stenosis. METHODS Totally 100 patients (Group A) with suspected coronary artery diseases (CAD)(More)
OBJECTIVE To compare the coronary artery bypass graft (CABG) imaging between 16-slice spiral CT and 64-slice spiral CT. METHODS Totally 27 patients with CABG received multi-slice spiral CT imaging and the results were retrospectively analyzed. Among them, 8 patients received 16-slice spiral CT scanning, 19 patients received 64-slice spiral CT scanning. (More)
