Objective To assess the correlation between time during admission to percutaneous coronary intervention (PCI) and left ventricular function recovery of acute myocardial infarction (AMI) by two-dimensional speckle tracking imaging (STI).The clinical value of STI in assessing therapeutic effect of AMI treated by PCI and estimation of the prognosis were discussed.Methods Sixty-one AMI patients who had AMI for the first time and had been treated by primary PCI were enrolled.Dynamic images were acquired before PCI,at 7 days after PCI and 30 days after PCI and analyzed by STI.The time during admission to PCI of AMI patients was recorded accurately.Dynamic images were analyzed for longitudinal peak systolic strain (LPSS) values (global,infarcted area) by STI.According to the comparison of left ventricular ejection fraction(LVEF) before PCI and 30 days after PCI,patients were divided into left ventricular function improved group (ΔLVEF≥5 %) and not-improved group,and the values of LPSS and time during admission to PCI were compared between the two group respectively.Results Compared to not-improved group,the time during admission to PCI in improved group was lower ( P <0.001),infarcted segmental LPSS at 7 days after PCI ( P <0.05) and both global ( P <0.001) and infarcted segmental LPSS ( P <0.001) at 30 days after PCI in improved group were higher than those in not-improved group.Linear regression analysis showed that both global and infarcted segmental LPSS were significant correlated to LVEF respectively ( P <0.001,all).Infarcted segmental LPSS at 7 days after PCI were correlated to the time during admission to PCI ( P <0.05).LVEF ( r =0.303,P <0.05),global ( r =0.300,P <0.05)and infarcted segmental LPSS ( r =0.590,P <0.001) at 30 days after PCI were correlated to the time during admission to PCI.Conclusions STI provides reliable and useful clinical information for the assessment of therapeutic effect of AMI treated by PCI and estimation of the prognosis by sensitively presenting the close correlation between time during admission to PCI and left ventricular function recovery of AMI patients.

Objective To assess left ventricular(LV) longitudinal strain in patients with coronary heart disease by two-dimensional speckle tracking imaging (2DSTI),and to explore the clinical value of 2D longitudinal strain in detecting myocardial ischemia. Methods Forty-four patients with coronary heart disease (CHD group) and 28 age-matched subjects (control group) were enrolled into this study. The two-dimensional data were obtained in apical 4-chamble, 2-chamber and long axis view. And the longitudinal strains of every segments, the average longitudinal strain of LV 18 segments (SL18), the average longitudinal strain of 12 segments (SL12,excluded the 6 apical segments) were analyzed. Results In the patients with CHD, the longitudinal strain of ischemia segments and the global LV longitudinal strain were significantly decreased than that of the control subjects. Both in patients with CHD and in control subjects,the longitudinal strains in apical segments were higher than that of middle and basal segments. There was significant difference between SL18 and SL12 ( P=0.027 in CHD group and P =0.003 in control group).Receiver operating curve (ROC) analysis demonstrated that the cutoff point of SL18 to detect myocardial ischemia was - 18.8% (sensitivity 80.2% and specificity 74.1% ) ,and the cutoff point of SL12 to detect myocardial ischemia was - 17.8% ( sensitivity 81.7% and specificity 85.6% ). Conclusions 2D longitudinal strain was sensitive to detect myocardial ischemia, SL12 was better than SL18 in detecting myocardial ischemia. 2DSTI might be useful for identifying patients with severe CHD.

Objective To assess the left ventricular function of patients with acute myocardial infarction (AMI) and its correlation with cardiac troponin T (cTnT) and specific manifestation of electrocardiogram (ECG) by automated function imaging (AFI) of two-dimensional speckle tracking imaging.Methods Forty-six AMI patients who had AMI for the first time and had been treated by primary percutaneous coronary intervention and 30 healthy controls who were age and sex-related to infarct group were involved.The values of cTnT within 24 hours after admission of AMI patients were recorded and the values of ST segment elevation were measured accurately.All the subjects were analyzed for longitudinal peak systolic strain (LPSS) values and the bull' s eyes by AFI.Results Compared to control group, left ventricular ejection fraction (LVEF), global and infarcted LPSS of infarct group were significantly different and the values of ST elevation of infarct group were higher than those of control group.Both global,infarcted segmental LPSS were significant closely correlated to LVEF and cTnT,respectively (P<0.001,all).Both global, infarcted segmental LPSS were correlated to ST elevation (P <0.05,all).Global LPSS had the closest correlation with LVEF (r = -0.565, P<0.001) and so did infarcted LPSS with cTnT (r = 0.432, P <0.01).Conclusions As a procedural simple and rapid diagnostic tool,AFI provides reliable and useful information of the assessment of AMI.Both global and infarcted segmental LPSS have well described left ventricular function of AMI patients.Compared to LVEF, LPSS was more closely correlated to cTnT and ST segment elevation, which meant that LPSS was more sensitive and more closely related to real infarct size and actual involved range of AMI.

Objective of this study was to detect the expression of HtrA2 and WT1 mRNA in acute myeloid leukemia (AML) and investigate the relationship of their expression levels with clinical variates and correlation between them. The expression levels of HtrA2 and WT1 were measured by RQ-PCR in bone marrow cells in 104 newly diagnosed AML patients and leukemia cell lines (K562, HL-60, NB4, Kasumi-1, U937), and the relationship between expression level and clinical parameters (age, sex, WBC count, diagnosis and prognosis) was investigated. The results showed that (1) the expression of HtrA2 gene in newly diagnosed AML was lower than that of the normal controls (P < 0.01), while expression of WT1 gene in newly diagnosed AML was higher than that of the normal controls (P < 0.01), the expression levels of HtrA2 and WT1 genes both did not correlate with age, sex and WBC counts of patients. There were no significant difference of HtrA2 gene expression between different NCCN prognosis group, while WT1 gene expression in better-risk group was significantly lower than that in intermediate-risk group (P = 0.003). The HtrA2 expression level rose after treatment in both CR group and non-CR group (P < 0.05), while WT1 expression level significantly decreased after treatment only in CR group (P < 0.01). Negative correlation between HtrA2 and WT1 expression was also observed (r = -0.249, P = 0.011). It is concluded that the low expression of HtrA2 and high expression of WT1 are closely related with occurrence and development of acute leukemia, so up-regulating expression of HtrA2 and interfering expression of WT1 may become the targets for leukemia therapy in the future.

The objective of this study is to develop a sensitive and reliable high-performance liquid chromatography mass spectrometry (LC-MS) method for simultaneous determination of artemisinin, arteannuin B, artemisic acid, and scopoletin, and study the pharmacokinetics of the four constituents in mouse serum after oral administration of the four components to mice. The analytical column used was Agilent Zorbax SB-C18 (2.1 mm x 150 mm, 5 mm). The mobile phase was acetonitrile: 0.5% acetic acid (60: 40) and the flow rate was 0.3 mL x min(-1). The temperature of the column was 40.0 degrees C. In this condition, we established an analysis method to simultaneously determine the four components. A sensitive and specific liquid chromatography-mass spectrometric (LC-MS) method was developed and validated for the determination of artemisin in derivatives in mice plasma. The method we established has a linear range of 5-3 000 μg x L(-1) with a good sensitivity and specificity for all of the four components. This method is simple, rapid, accurate and suitable for the determination of the content of the four compounds.
