ObjectiveTo investigate the quality of life (QOL) of old patients with cardiovascular diseases in community. Methods100 old patients with cardiovascular diseases in Xiluoyuan, Beijing were investigated with WHOQOL-BREF. ResultsThe QOL-BREF scores in the dimensions of physical health, psychology, social relationships, and environment were (53.21±11.50), (53.27±15.99), (54.29±14.41) and (57.65±15.30) respectively. There was not significant difference between self-rating scores and scores in four dimensions of QOL-BREF (P>0.05). There was not significant difference of QOL-BREF scores in four dimensions between male and female, nor the ones whether complicated with diabetes (P>0.05). The incidence of satisfaction was 31% for QOL, 23% for health, and 62% for the healthy system as self-report. ConclusionThe QOL of the patients is related to diseases.

Objective To further investigate the threshold value and the dose-effect relationship of infrasound on the rat pallium, and to observe the effects on the pallium's ultrastructure. Methods Rats were exposed to 16 Hz, 90 dB infrasound for 2 hours daily. With a transmission electron microscope, changes in the ultrastructure of the cortex of the rats' parietal lobes were observed 2 hours, 3 days and 7 days after the treatment. Results There were no changes in the ultrastructure of the pallium in rats which had been exposed for 7 days or 14 days. Denaturation appeared when the rats had been exposed for 21 days, 28 days or 35 days. Denaturation become more serious as the exposure time increased beyond 21 days. Denaturation and damage gradually returned to normal with time after exposure. Conclusion 16 Hz, 90 dB infrasound exposure over an extended time may cause denaturation and other changes in the ultrastructure of the pallium in rats. Such changes can return to normal with time.

Objectives To explore the change of interleukin-17 (IL-17) in Kawasaki disease (KD). Methods Fourty KD pediatric patients, among them 12 patients with echocardiographic abnormalities in acute phase, 25 age-matched non-KD patients were enrolled. The level of serum IL-17 was measured by enzyme linked immunosorbent assay in acute and convalescent phase of KD patients and non-KD patients. At the same time, C-reactive protein (CRP), globulin, albumin were detected. Results In acute phase of KD patients, the level of serum IL-17 were signiifcantly higher than that in convalescent phase of KD patients and non-KD patients (P<0.05). The level of serum IL-17 was no signiifcant differences in convalescent phase of KD patients and non-KD patients (P>0.05). In acute phase of KD patients with echocardiography abnormalities, the level of serum IL-17 was signiifcantly higher than that with non-echocardiography abnormalities (P<0.05). The level of serum IL-17 in acute phase of KD patients were positively correlated with CRP and globulin (r=0.750, 0.750, P<0.05), and negatively correlated with albumin (r=-0.779, P<0.05). Conclusions IL-17 may be involved in KD immune pathogenesis. Serum IL-17 is one of the activity index of KD, which associ-ated with cardiovascular damages.

Objective To appraise the clinical value of velocity vector imaging(VVI) by analyzing the peak systolic velocities,strain and strain rate of ventricular segments in patients with DDD pacing. Methods eventeen patients with DDD pacing were enrolled in this study. The peak systolic velocities, strain andstrain rate of ventricular segments were measured with VVI. The difference at baseline and after pacemaker implantation was analyzed. Results Left and right ventricular (LV and RV) longitudinal peak velocities at baseline and after DDD pacing were significantly decreasing from basal, mid to apical segments. But no significant difference was found in longitudinal strain,strain rate and radial motion characteristic of LV. The mean systolic velocities and strain rate at baseline and after pacemaker implantation and strain with pacing of RV posterior septum and free wall were higher than those of posterior septum and lateral segment of LV respectively. The mean strain and strain rate of RV after pacing were higher than that of LV. Compared with the values at baseline, mean strain of LV with pacing was lower significantly. Conclusions VVI can accurately assess ventricular systolic function in patients with DDD pacing, and can become a powerful means in assessing the regional myocardial function.

Objective To study the recovery of the peripheral lymphocyte subsets in patients underwent allogeneic peripheral blood stem cell transplantation (allo-PBSCT) and guide the prevention and treatment of infection. Methods Indirect immunofluorescence assay was used to detect the lymphocyte subsets, such as T cell subsets (CD3, CD4, CD8). B cell (CD19) and natural killer cell(CD56) at 1, 3, 6, 12, 18months post transplantation, in the meantime, lymphocyte subsets of 32 samples from healthy blood donors were tested as normal control values. Results CD+3, CD+4 and CD+8 ceils significantly decreased than that of normal control at 1 month post transplantation, the recovery of CD+3 T cells was within 3-12 months, CD+4 and CD+8 T cells recovered to normal at 6 months and 3 months post transplantation respectively, CD+4/CD+8 ratio were not significantly lower than that of normal control at different stages, CD+4/CD+8 ratio reversed only at 6 months post transplantation. CD+19 and CD +56 T cells recovered quickly and they were more than normal proportion at 3 months post transplantation. The CD+3, CD+8 T cells and CD+4/CD+8 ratio were statistically higher in HLA haploidentical allo-PBSCT patients than that in HLA identical allo-PBSCT at 3 months post transplantation. There were no difference between the two groups at 1, 6, 12, 18 months post transplantation.The patients with cGVHD had significantly higher CD+4 cells than those without cGVHD at 1 month after transplantation. There was no significant difference in all of the lymphocyte subsets at 3, 6, 12, 18 months after transplantation between them. Conclusion Allo-PBSCT has a hastened immune reconstitution, which was not delayed by the incompatibility of HLA and the development of cGVHD.
