AIM: To study the signal transduction pathway of apoptosis initiation induced by homoharringtonine in HL-60 cells. METHODS: After establishing the model of apoptosis initiation induced by homoharringtonine in HL-60 cells, at the point of apoptosis initiation, molecular caspase-3, Bcl-2, Bax and Fas/FasL were measured with flow cytometry and transmission electron microscope. ERK2 and P38 expression in HL-60 cells were detected by using immunohistochemistry. RESULTS: The model of apoptosis initiation induced by homoharringtonine was established in HL-60 cells. At the point of apoptosis initiation, upregulation of caspase-3 and decrease in Bcl-2/Bax were observed. However, the expression of Fas/FasL did not significantly change. ERK2 expression decreased and P38 expression increased. CONCLUSIONS: Caspase-3, Bcl-2, Bax and mitogen activated protein kinase pathways were involved in signal transduction of apoptosis initiation induced by homoharringtonine in HL-60 cells. [

Objective To evaluate the regional cardiac function for patients with coronary heart disease (CHD) with multiple tissue Doppler imaging (TDI) parameters in rest state and to discuss the value of regional cardiac function in diagnosing CHD.Methods Forty-seven patients with chief complain of chest pain underwent TDI examination.Maximum systolic velocity (Sm),maximum early diastolic velocity (Em),maximum late diastolic velocity (Am),isovoluminal contraction time (IVCT) and isovoluminal relaxation time(IVRT) of 16 segments of left ventricle were measured.All the patients underwent coronary angiography (CAG) at the same time.CHD was diagnosed by at least one coronary artery with no less than fifty percent diametric stenosis.Segments dominated by coronary artery with fifty to ninety and more than ninety percent diametric stenosis were defined as moderate and severe lesion segments respectively.Others were non-lesion segments.Results There was no significant difference of sex,age,heart rate,CHD risk factors,left ventricular ejection fraction (LVEF) and E/A among non-CHD (13 cases),one-lesion(11 cases),two-lesion (11 cases) and three-lesion (12 cases)(P ＞0.05).Compared with those in non-lesion segments (390sections),Sm,Em and Em/Am decreased and IVRT prolonged in both moderate lesion segments (162 sections) and severe lesion segments (144 sections) (P ＜ 0.01).IVCT prolonged only in severe lesion segments (P ＜0.05),but not in moderate lesion segments.If setting a criterion that no less than three segments with Sm ＜ 2.50 cm/s and IVRT ＞ 87 ms was for CHD diagnosis,the sensitivity,specificity,positive predictive value,negative predictive value and accuracy were 79.4％ (27/34),84.6％ (11/13),93.1％ (27/29),61.1％(11/18) and 80.9％(38/47).Conclusions In rest state,regional cardiac function of lesion segments in CHD patients shows changes of decreased systolic and diastolic velocity and prolonged isovoluminal time.Analyzing segmental cardiac velocity and time comprehensively may help to diagnose CHD.

Objective To evaluate the coronary lesions with two-dimensional strain echocardiography. Methods Sixty-seven patients with suspected coronary heart diseases who underwent coronary angiography were divided into two groups. Forty-two of them with coronary stenosis ≥70% were considered as patient group, and the other 25 with coronary stenosis ＜50% were regarded as control group. Two-dimensional strain was performed in all patients within 24 h before coronary angiography. Longitudinal systolic strain rate (SRs), early (SRe) and late (SRa) diastolic strain rate, systolic strain (Ss), and time to SRe (T-SRe) were measured and compared. Results Ss, SRs, SRe and SRe/SRa decreased significantly in regions controlled by coronary artery with ≥70% stenosis in patient group compared with those controlled by coronary artery with ＜50% stenosis in control group. SRs and SRe were the independent predictive factors of coronary stenosis ≥70%, and the sensitivity and specificity of SRe ＜0.91 to identify coronary stenosis ≥70% was 72.46% and 89.65%, respectively. Conclusion Two-dimensional strain echocardiography may accurately evaluate the coronary lesions by detecting regional myocardial diastolic function.
