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)
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 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 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)
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 analyze clinical characteristics in young and aged patients with coronary artery disease (CAD). METHODS The clinical and coronary angiographic data were compared between young (PCAD, male < 55 years old, n = 74, female < 65 years old, n = 71) and aged (CAD, male > 55 years old, n = 106, female > 65 years old, n = 111) patients. Seventy-one(More)
OBJECTIVE To explore the scan technique and image quality of coronary angiography with dual source computed tomography (CT) without oral metoprolol preparation. METHODS Plain and enhanced dual source CT coronary angiography without oral metoprolol preparation was prospectively performed in 600 patients. Calcium scoring with plain scan images as well as(More)
OBJECTIVE Statins are still underused for the prevention of cardiovascular disease (CVD) in China. Hence, we conducted a systemic review on the pharmacology, clinical efficacy, and adverse events of atorvastatin, as well as on patient adherence. DATA SOURCES We conducted a systemic search in PubMed with the following keywords: "atorvastatin"(More)
