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.

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.

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 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.

To optimize the immunization strategy against HIV-1, a DNA vaccine was combined with a recombinant vaccinia virus (rTV) vaccine and a protein vaccine. Immune responses against HIV-1 were detected in 30 female guinea pigs divided into six groups. Three groups of guinea pigs were primed with HIV-1 DNA vaccine three times, boosted with rTV at week 14, and then boosted with gp140 protein at intervals of 4, 8 or 12 weeks. Simultaneously, the other three groups of animals were primed with rTV vaccine once, and then boosted with gp140 after 4, 8 or 12 weeks. The HIV-1 specific binding antibody and neutralizing antibody, in addition to the relative affinity of these antibodies, were detected at different time points after the final administration of vaccine in each group. The DNA-rTV-gp140 immune regimen induced higher titers and affinity levels of HIV-1 gp120/gp140 antibodies and stronger V1V2-gp70 antibodies than the rTV-gp140 regimen. In the guinea pigs that underwent the DNA-rTV-gp140 regimen, the highest V1V2-gp70 antibody was induced in the 12-week-interval group. However, the avidity of antibodies was improved in the 4-week-interval group. Using the rTV-gp140 immunization strategy, guinea pigs boosted at 8 or 12 weeks after rTV priming elicited stronger humoral responses than those boosted at 4 weeks after priming. In conclusion, this study shows that the immunization strategy of HIV-1 DNA vaccine priming, followed by rTV and protein vaccine boosting, could strengthen the humoral response against HIV-1. Longer intervals were better to induce V1V2-gp70-specific antibodies, while shorter intervals were more beneficial to enhance the avidity of antibodies.

High temperature and humidity stress during seed growth and development of spring soybean can result in seed deterioration in South China. We isolated two genes (GmSBP and GmSBPL) encoding putative SBP proteins from soybean (Glycine max (L.) Merr.) to study their biological functions and response to abiotic stress,. The two SBP proteins are hydrophilic and incomplete membrane ones. Real-time quantitative (RT-PCR) analysis reveals that the expression of the two genes in the developing seeds of the seed deterioration resistant cultivar Xiangdou No. 3 and sensitive cultivar Ningzhen No. 1 was significantly affected by high temperature and humidity treatment. Meanwhile, the levels of sucrose and soluble sugar in the developing seeds of both cultivars were also affected under high temperature and humidity stress. During seed growth and development, the expression of the two genes as well as the levels of sucrose and soluble sugar reached the highest at 30 days after flower. GmSBP2 and GmSBPL were found to be differentially expressed in different soybean tissues. Sub-cellular localization indicated that two genes were located in cytoplasm and cell membrane. Our results indicate that GmSBP2 and GmSBPL might be involved in the response to abiotic stress, which will enrich our understanding of pre-harvest seed deterioration and resistance in soybean from one side.
