BACKGROUND Emerging evidence suggests that stem cells can be used to improve cardiac function in patients after acute myocardial infarction. In this randomized trial, we aimed to use Doppler tissue tracking and strain imaging to assess left ventricular segmental function after intracoronary transfer of autologous bone-marrow stem cells (BMCs) for 6 months'(More)
AIM To investigate whether bone marrow-derived denritic cells pulsed with tumor lysates induce immunity against gastric cancer ex vivo. METHODS c-kit(+) hematopoietic progenitor cells were magnetically isolated with a MiniMACS separator from BALB/c mice bone marrow cells. These cells were cultured with cytokines GM-CSF, IL-4, and TNFalpha to induce their(More)
OBJECTIVE To investigate the safety of autologous bone marrow mononuclear cell (BM-MNCs) transplantation by intracoronary infusion in patients with acute myocardial infarction (AMI). METHODS One hundred and eighty-four patients with AMI treated with percutaneous coronary intervention (PCI) were randomized in a 1:1 way to either intracoronary(More)
OBJECTIVE To investigate the effects of emergent intracoronary autologous bone marrow mononuclear cell (BM-MNC) transplantation on left ventricular function and myocardium lesion area in patients with first acute inferior-wall myocardial infarction. METHODS Forty patients with first onset of acute inferior-wall myocardial infarction, 28 males and 12(More)
OBJECTIVE The aim of this study is to identify short-term result of cell transplantation in idiopathic dilated cardiomyopathy (IDC) patients who were treated by intracoronary transplantation of autologous mononuclear bone marrow cells (BMCs) in addition to standard therapy. METHODS Based on given standard therapy, eighteen patients with idiopathic dilated(More)
BACKGROUND Quantitatively assessing myocardial perfusion and its reserve is of great importance for the diagnosis and stratification of patients with coronary artery disease (CAD), and represents an important goal of myocardial contrast echocardiography. In this study we sought to test the usefulness of low dose dobutamine stress real-time myocardial(More)
We develop 3D automatic feature construction system to efficiently quantify different types of the lower limb alignment and the hip fracture. This system has the potential to provide useful information regarding the risk of knee and hip osteoarthritis, and should be considered an alternative method for the measurement of the lower limb alignment and the hip(More)
OBJECTIVE To evaluate the value of quantitative real-time myocardial contrast echocardiography (RT-MCE) combined with low dose dobutamine stress test in the detection of coronary artery disease (CAD), and to assess the contribution of collateral blood flow (CBF) to myocardial perfusion. METHODS Twenty-six hospitalized patients referred for coronary(More)
To solve the misjudgment of noise and vein information in features extraction from low quality images, a novel method based on LWF (Linear weighting function) immune-clone algorithm is proposed in this paper. The method can produce initial antibody by using adaptive threshold method, obtain weighting function by curve fitting, and denoise and enhance border(More)
