Objective:To investigate the expressions and significance of tyrosine kinase receptor EphA2 and its ligand ephrinA1 in human malignant gliomas and their correlation with tumor angiogenesis. Methods:The expressions of EphA2, ephrinA1, and CD105-stained microvessel density (MVD) were detected via immunohistochemical assay in 62 glioma tissues and 8 normal brain tissues. The correlation between EphA2 and ephrinA1 expression and microvessel counts in the glioma tissues were assessed. Results:Immunohistochemical staining results revealed that variable levels of EphA2 and MVD expression were significantly higher than that of the normal brain samples. Statistical difference was observed in EphA2 and MVD expressions between human gliomas and normal brain samples (P<0.01). The positive rate of EphA2 and MVD expressions was significantly higher in high-grade gliomas (WHO III-IV) than that in low-grade gliomas (WHO I-II) (P<0.01). EphrinA1 was expressed at low levels in most malignant gliomas, and the increased ephrinA1 expression was associated with lower-grade histology. MVD was significantly positively correlated with EphA2 expression (r=0.713, P<0.01) and significantly negatively correlated with ephrinA1 expression (r=-0. 772, P<0.01). EphA2 was significantly negatively correlated with ephrinA1 expression (r=-0.912, P<0.01). Conclusion:Specifically over-expressed EphA2 and its low-expressed ligand ephrinA1 in malignant gliomas may be closely correlated with the invasion and malignant degree of gliomas. Cooperation is involved in the angiogenesis and has an important function in the initiation and progression of gliomas.

Objective To evaluate the efficacy and safety of higenamine hydrochloride(HG) stress echocardiography for diagnosis of coronary artery disease (CAD). Methods The study was designed as prospective,randomized,open-labled,positively controlled and crossover phase II multi-center clinical research.Ninety subjects who were suspected to have CAD were enrolled.HG dosage was titrated at 0.5,1, 2,4 μg.kg -1.min-1every 3 min.Adenosine was injected 140 μg.kg -1.min-1for 6 min with total dosage 0.8 mg/kg.Visual assessment of the left ventricle wall motionand 17-segment model were used for analysis of stress echocardiography.CAD was defined as identifying >50% diameter stenosis in at least one major coronary artery by coronary angiogram.All adverse reaction were recorded. Results For HG group,the sensitivity,specificity,accuracy,positive predictive value and negative predictive value were 28.9%,89.7%, 57.1%,76.5% and 47.8%,respectively;for adenosine group,they were 26.7%,94.9%,58.3%,85.7%and 47.1%,respectively. There was no significant difference between the two groups( P > 0.05). The diagnostic sensitivities of HG and adenosine echocardiography for single vessel stenosis were 11.1% and 5.6%,respectively( P >0.05).Both HG and adenosine echocardiography have the same sensitivity with 37.5% for double vessel stenosis and 44.4% for triple vessel stenosis.Advers reaction rate was 84.4% in HG group and 92.2% in adenosine group( P >0.05).Conclusions HG stress echocardiography for CAD diagnosis has high specificity,good safety and low sensitivity,which are similar to adenosine echo.

Objective To explore the association of MTHFR C677T polymorphism and birth body mass with the vulnerability of autism in Chinese Han population. Methods Totally 1 505 children with au-tism have been recruited,using the diagnosis and statistical manual,4th revised version ( DSM-IV-R) diag-nostic criteria for autism. And 1 308 healthy control subjects sex matched with the children with autism were enrolled for the study. All the participants were identified the birth body mass ( kg) according to the birth medical recording. All the subjects were examined the MTHFR C677T genotypes,using the polymerase chain reaction- restrict fragment length polymorphism (PCR-RFLP) methods. The frequencies of genotypes,alleles and birth body mass were compared between autism and healthy control groups using the chi-square and other tests. Results The MTHFR C677T (P=0. 004,OR=1. 18,95% CI=1. 02-1. 29),low birth body mass (<2. 5 kg) (P=0. 001,OR=1. 04,95%CI=1. 02-1. 06),and their interactive effects ( P=0. 0001,OR=2. 18,95%CI=1. 44-3. 32) were associated with the vulnerability of autism. Conclusions The MTHFR C677T polymorphism,low birth body mass and their interactive effects might be associated with susceptibility of autism in Chinese Han population.
