Objective To investigate the value of real-time three-dimensional echocardiography 17 regional volume curves index in patients with heart transplantation. Methods Sixty patients with heart transplantation (no rejection), ten patients with heart transplantation (rejection), forty subjects with normal left ventricular(LV) function were examined by Philips iE33 with a X3-1 probe. Results Parameter index of 17 segment time to minimal systolic volume in patients with heat transplantation (rejection) were more than those in patients with heart transplantation (no rejection) and in subjects with normal LV function(all P <0.05). Parameter index of 17 segment time to minimal systolic volume were not significantly different in patients with heart transplantation (no rejection) compared with subjects with normal LV function. Parameter index of Tmsv16-SD (%), Tmsv12-SD (%) and Tmsv6-SD (%) show higher sensitivity and specificity for forecast rejection after heart transplantation. Conclusions Real-time three-dimensional 17 regional volume curves index can fast forecast early rejection after heart transplantation.

AIM: To investigate the influences of bypass-activated complement and TNF-? on intercellular adhesion molecule 1(ICAM-1) expression in endothelial cells, and polymorphonuclear neutrophil-endothelial cell (PMN-EC) adhesion. METHODS: In vitro, zymosan-activated human serum(ZAHS) and/or TNF-? directly stimulated the HUVECS monolayers. PMN-EC adhesion percentage was measured, and modified whole-cell ELISA was used for measurement of ICAM-1. RESULTS: ZAHS alone resulted in no significant change in the degree of PMN adhesion and the level of ICAM-1. Activation of HUVECS with TNF-? followed by ZAHS stimulation resulted in greater increase in PMN-EC adhesion and ICAM-1 expression, as compared with the activation with TNF-? alone. CONCLUSION: Bypass-activated complement can promote ICAM-1 expression and neutrophil -endothelium adhesion induced by TNF-?, and so it is effective for promoting inflammation.

Objective To investigate longitudinal systolic function of transplanted heart using two dimensional speckle tracking echocardiography and tissue Doppler imaging.Methods 56 consecutive patients with heart transplant were recruited,according to myocardial biopsy and 1 year's follow up,they were divided into non-rejection group (group A) and rejection group (group B).36 healthy controls (group C) were also randomly recruited.Left ventricular ejection fraction (LVEF),pulmonary arterial systolic pressure,tricuspid annular plane systolic excursion (TAPSE),tricuspid annular plane systolic velocity (TAS') and global longitudinal strain (GLS) were calculated via Qlab 9.0 analysis software offline.Results Compared with group C,LVEF was reduced in group B (P ＜0.01).Differences of GLS,TAPSE,and TA-S' among groups were all statistically significant (P ＜0.01),group B＜group A＜ group C.LVEF,TAPSE and TA-S' were correlated with GLS (r =-0.64,r =-0.69,r =-0.71 ; all P ＜ 0.01).Conclusions Left and right ventricles were a functional unity,the systolic function of which was impaired in patients with heart transplant.

Objective To investigate whether the left ventricular delayed contraction site determined by tissue Doppler imaging might be an optimal left ventricular lead position for improved outcomes of cardiac resynchronization therapy (CRT) in patients with non-ischemic cardiomyopathy. Methods Thirty-three patients subjected to CRT were selected, and all were performed conventional ultrasound cardiography and tissue Doppler examinations before operation. The left ventricular delayed contraction site was determined according to the interval between the onset of QRS and the peak systolic velocity. Retrograde coronary venography was performed during operation, and the left ventricular lead site was selected according to the left ventricular delayed contraction site determined by tissue Doppler examination before operation. The coronary sinus lead site was determined under the guidance of X ray of dorsaventral, lateral, right anterior oblique and left anterior oblique positions. Patients were divided into group A(n=20, the left ventricular lead site was in line with the delayed contraction site) and group B (n=13, the left ventricular lead site was not in line with the delayed contraction site). Results There was no significant difference in age, NYHA grading, left ventricular end-systolic volume(LVESV), left ventricular ejection fraction(LVEF), pulmonary arterial systolic pressure, QRS width and Ts-SD between the two groups before operation(P> 0.05). Six months after CRT, there was no significant difference in NYHA grading, LVESV and mitral regurgitation(MR) grading between the two groups(P>0.05), while the increase in LVEF and decrease in LVESV of group A were more significant than those of group B (P<0.01). Conclusion In patients with non-ischemic cardiomyopathy, CRT significantly improves left ventricular performance, and the more favourable outcomes are achieved in those pace at the delayed contraction site. Tissue Doppler imaging may help to guide the implant of left ventricular lead.

Objective To examine supine fulcrum pressurized radiograph to predict spinal flexibility in adolescent idiopathic scoliosis (AIS). Methods 1. Empirical study: put two points (A and B) on one side of the plastic stick and one point on the other side ( C), pressurize on the plastic stick when point C is in the middle of A and B, and then measure the projection shifting of point A. Repeat the pressure test when the distance between A and C doubled. Analyze the effect of increasing distance on diminishing pressure. 2.Clinical study :45 patients ( 16 males and 29 females) underwent standing anteroposterior radiograph ,fulcrum lateral flexion radiograph, supine lateral flexion radiograph. The Cobb's angles were measured and the flexibility ratio was determined on preoperative fulcrum radiograph. Results (1) If the length of A and C was 25 cm, pressurize on point C, when pressure quantitative scale number located 1 scale and 2 scale of the rule, projection shifting of point A were 5 cm and 10 cm. If the length of A and C was 50 cm, pressurize on point C, when pressure quantitative scale number located 1 scale and 2 scale of the rule, projection shifting of point A were 8 cm and 15 cm. The longer the distance, the lesser the pressure force of plastics stick. (2)The Cobb angles and curve flexibility provided by fulcrum lateral flexion radiograph had significant difference from that provided by supine lateral flexion radiograph in male group and female group. Cobb angles of male group was 28. 6°± 4. 1 °, 16. 7°± 4. 6° respectively (t= 7. 438, P ＜ 0. 01 )and curve flexibility was 47. 6% ±8. 1% ,69. 4% ± 8. 5% respectively( t = 7. 438, P ＜ 0. 01 ). Cobb angles of female group was 24.5°± 2. 7°,12. 6°±2. 4° respectively(t = 17. 540,P ＜0. 01 )and curve flexibility was 53.4% ±5.2% ,76. 0% ±4. 7% respectively(t = 17. 54, P ＜ 0. 01 ). The flexibility of spinal main curve of female patients was obviously higher than male patients. Conclusions Supine fulcrum pressurized technique can make up for the insufficiency of supine lateral flexion technique, and provide a convenient, safe, precise and useful method for evaluation of spinal flexibility in AIS.
