ObjectiveTo analyze the characteristic of the T peak-end interval (Tpe) in dilated cardiomyopathy(DCM) patients with heart failure and its significance in evaluation of global dispersion of ventricular repolarization.MethodsFifty-three inpatients were enrolled in this study,which included 28patients with DCM and heart failure (DCM group),and 25 patients with supraventricular tachycardia and without structural heart disease (control group).The Tpe and the dispersion of QT interval (QTd) from the 12-lead surface electrocardiogram(ECG) were acquired and measured,and consequently the corrected numerals of the average of Tpe (Tpe-AVEC),the maximal Tpe (Tpe-MAXC) were acquired.ResultsThe levels of Tpe-AVEC,Tpe-MAXC and QTd in DCM group were significantly higher than those in control group [ ( 106.31 ±26.34) ms vs.(82.72 ± 10.01 ) ms,(234.05 ± 69.75) ms vs.( 119.15 ± 11.55 ) ms,( 119.17 ± 67.62) ms vs.( 39.74 ± 17.04 ) ms ] ( P ＜ 0.05 or ＜ 0.01 ).ConclusionsThe global dispersion of ventricular repolarization is significantly increased in patients with DCM and heart failure.The Tpe-AVEC and Tpe-MAxc are recommended to be used for evaluating the dispersion of ventricular repolarization as the prognostic index in patients with DCM and heart failure.

Purpose To investigate the clinical, imaging and pathologic characteristics of dedifferentiated chondrosarcoma.Methods The clinical and pathological data were reviewed in 11 cases of dedifferentiated chondrosarcoma.Results Most of these patients were male (7/11). The mean age was 57.1 years.Most tumors were located in the long bone and pelvis. Imaging showed that bones were extensively destroyed.There was calcification or ossification on focus of infection. The gross specimen showed that cartilage component was located within bone and dedifferentiated sarcoma was found out of the bone.Microscopically, well differentiated chondrosarcoma and poorly differentiated sarcoma components were observed. Six patients died and the average survival time was 14 months.Conclusions Dedifferentiated chondrosarcoma is an unusual subtype of chondrosarcoma with pleomorphic alterations. Further understanding the pathologic features of the tumor is important to increase the accurancy of diagnosis.

Objective To investigate the effects of valproic acid ( VPA) on cell proliferation and cell cycle in human pancreatic cancer cell line PaTu8988 in vitro. Methods PaTu8988 cells were treated with VPA in concentration of 0, 0.2, 1.0 or 5.0 mmol/L for 24 h and 48 h respectively. Cell viability was measured by WST-8 assay. Cell cycles were detected by flow cytometery. Dimethyl sulfoxide added to the medium was used as blank control group, while PBS added to the medium was used as PBS group. Results After VPA treatment for 24 h, the inhibition rate of VPA 5.0 mmol/L group was 18.9% , which was significantly higher than those in control group, PBS group and VPA 0.2, 1.0 mmol/L group (0, 4.4% , 6.8%, 6.1% , P <0.05). After 48 h, the inhibition rates of VPA 1.0, 5.0 mmol/L were 12.9%, 25.9% , which was significantly higher than those in control group, PBS group and VPA 0.2 mmol/L group (0, 6.2% , 4.6% , P <0.01). After VPA treatment for 24 h, the proportions of G2 phase cell in VPA 1.0, 5.0 mmol/L group were ( 26.57 ± 1.88) % , ( 34.11 ± 4.74 ) % , which was significantly higher than those in PBS group, control group, VPA 0.2 mmol/L group [(10.72 ± 2.02)% , ( 13.53 ± 2.28)% , (13.81 ±2.40)%, P <0.01 ], the changes 48 h after VPA treatment was consistent with the changes 24 h after VPA treatment. Conclusions VPA may significantly suppress the cell proliferation of human pancreatic cancer cell line PaTu8988, and induce cell cycle arrest in G2 phase in a time and dose-dependent manner.
