Erythropoietin-producing hepatoma (EPH) receptors are considered the largest family of receptor tyrosine kinases and play key roles in physiological and pathologic processes in development and disease. EPH receptors are often overexpressed in human malignancies and are associated with poor prognosis. However, the functions of EPH receptors in epithelial-mesenchymal transition (EMT) remain largely unknown. This review depicts the relationship between EPH receptors and the EMT marker E-cadherin as well as the crosstalk between EPH receptors and the signaling pathways involved EMT. Further discussion is focused on the clinical significance of EPH receptors as candidates for targeting in cancer therapeutics. Finally, we summarize how targeted inhibition of both EPH receptors and EMT-related signaling pathways represents a novel strategy for cancer treatment.

OBJECTIVEThe impact of late incomplete stent apposition (ISA) post sirolimus eluting stent (SES) implantation in patients with acute coronary syndrome (ACS) on long-term clinical outcomes remains controversial. The aim of the present study was to evaluate the association between late ISA and clinical outcomes in patients with ACS compared with that with stable angina (SA).

METHODSFrom February 2005 to March 2007, 54 ACS patients and 83 SA patients were enrolled in this study, late ISA was determined by means of three-dimensional volumetric intravascular ultrasound (IVUS) analyses one year after SES implantation and clinical outcomes one year post IVUS were obtained in these patients.

RESULTSIn 219 treated lesions of the 137 patients, late ISA was documented in 25 lesions in 16 patients (20 ISA in 12 ACS patients vs. 5 ISA in 4 SA patients, P<0.001). Though lumen area in reference and stented segment, neointimal hyperplasia (NIH) area and percentage of NIH in stented segment, and external elastic membrane (EEM) area in reference segment were similar between two groups, EEM area in stented segment [(15.34+/-5.44) mm2 vs. (13.83+/-4.51) mm2, P=0.026], stented/reference segment EEM area ratio (1.13+/-0.22 vs. 1.02+/-0.18, P<0.001), plaque and media area [(8.43+/-3.93) mm2 vs. (7.01+/-2.93) mm2, P=0.002] was significantly lager in ACS group than that in SA group. Multivariable logistic analysis showed that ACS (OR 6.477 with 95% CI from 2.297 to 18.263, P<0.001) and stent length>or=23 mm (OR 3.680 with 95% CI from 1.181 to 11.469, P=0.025) were main independent factors of occurrence of late ISA. Incidence of main adverse cardiac events (MACE) one year post IVUS was similar between the two groups.

CONCLUSIONCompared with patients with SA, ACS patients had larger stented segment EEM area, plaque and media area as well as increased incidence of ISA. However, the incidence of MACE was similar in ACS and SA patients one year after IVUS.

OBJECTIVETo estimate the correlations between functional MRI (fMRI) parameters and the severity of chronic liver lesions of hepatitis B patients.

METHODS47 hepatitis B patients [6 with chronic hepatitis, 41 with cirrhosis (14 with Child-Pugh class A cirrhosis; 12 with class B cirrhosis; and 15 with class C cirrhosis)] and 10 normal volunteers, referred for measurements of apparent diffusion coefficient (ADC) values of the liver, perfusion imaging parameters, portal flow parameters and serum markers of hepatic fibrosis were included in the study. Diffusion-weighted imaging (DWI) with different b values and b value remainder was performed. Time to peak (TP), maximum slope of increase (MSI) and distribution volume (DV) were measured with dynamic contrast material-enhanced MR imaging. Portal velocity and portal flow with phase contrast (PC) were measured. The patients' serum hepatic fibrosis markers, including hyaluronic acid (HA), type-III-procollagen (PC III), laminin (LN) and type-IV-collagen (C IV), were measured and analyzed together with the fMRI results.

RESULTS(1) The mean ADC3 in Child A, B, C cirrhosis patients was significantly lower than that in the controls (P < 0.05 in Child A, and P < 0.05 in Child B). (2) There was a significant increase of time to peak and a decrease of maximum slope of increase (P < 0.01) in the Child A, B, C patients than in the normal controls. (3) There was a significant decrease in portal velocity in cirrhotic patients as compared to that of the controls and chronic hepatitis patients (P < 0.01). (4) The mean HA in Child A, B, C cirrhosis patients was significantly higher than that in chronic hepatitis patients and in the controls (P < 0.01); The mean LN in Child A, B, C cirrhosis was also significantly higher than that in chronic hepatitis patients and in normal controls (P < 0.01); The mean PC III in Child A, B, C cirrhosis was significantly higher than that in the normal controls (P < 0.01).

CONCLUSIONfMRI parameters can reflect some changes of the livers, therefore fMRI parameters are of value in clinical diagnosis and treatment of chronic hepatitis B patients.

OBJECTIVETo investigate the potential association of the C-reactive protein (CRP) gene +1444C/T polymorphism with symptomatic carotid artery stenosis.

METHODSPolymerase chain reaction-restriction fragment length polymorphism was used for the detection of CRP +1444C/T genotypes in 192 patients with symptomatic carotid artery stenosis and 197 healthy controls. Serum high sensitivity-CRP (hs-CRP) levels were measured by routine method.

RESULTSNo TT genotype was detected in this study. Patients with >70% stenosis had higher CC genotype compared with those with <70% stenosis after adjusting for major cerebrovascular risk factors (OR: 2.958; 95% CI: 1.198 - 7.305; P=0.019). CRP levels were significantly higher in patients than in controls. Subgroup analysis according to clinical characteristics (single or double stenosis; >70% or <70% stenosis) did not show difference in CRP levels. There was no significant difference in the prevalence of CT genotype between patients and controls, or between single and double stenosis (P>0.05).

CONCLUSIONThe CRP +1444 CC genotype is a risk factor for >70% carotid artery stenosis. The serum CRP level is associated with the presence of carotid stenosis. However, it is not associated with the number and severity of stenosis.

OBJECTIVETo locate the cluster region of loss of heterozygosity (LOH) in children with acute lymphoblastic leukemia (ALL), and explore the new tumor suppressor gene.

METHODSAllelic loss was analyzed by PCR with 15 microsatellite markers mapping on 6q16.3. The LOH was analyzed by bioinformatics. The relationship between LOH and clinical factors was further analyzed.

RESULTSThe frequency of LOH at least at one loci on 6q16.3 was 32.7%. The LOH in relapsed patients was higher than those in not relapsed. The higher frequency of LOH was observed in two regions of D6S1709-D6S1028 and D6S2160-D6S1580 at 6q16.3. GRIK2 may be a candidate of tumor suppressor gene. There are 12 ESTs may carry out new anti-oncogene. Patients with 6q LOH had higher WBC counts (P < 0.01), blast cells percentage (P < 0.01), relapse rate (P < 0.05) and chromosomal aberration (P < 0.05).

CONCLUSIOND6S1709-D6S1028 and D6S2160-D6S1580 are two regions of minimus deletion on 6q16.3 in which tumor suppressor gene may exist. The LOH on 6q16.3 may be a prognostic index of children with ALL.
