Objective To evaluate the applicability of formula R0, R1, R2 of ECToolbox software in measurement of left ventricular ejection fraction (LVEF) with gated myocardial imaging. Methods Rest gated myocardial SPECT with ~(99m)Tc-MIBI and rest gated blood-pool SPECT with ~(99m)Tc-RBC were performed on 64 patients (44 with CHD, 20 with hypertension). LVEFs were separately calculated with formula R0, R1, R2 of ECToolbox software, and the results were recorded as R0 LVEF, R1 LVEF and R2 LVEF, respectively, and compared with LVEFs from gated blood-pool imaging (GBPI LVEF). Results The LVEFs from formula R0, R1 and R2 were all significantly correlated with GBPI LVEF (r=0.905, 0.905 and 0.903, P<0.05, respectively). The accuracy within ±15% deviation from the GBPI LVEF was 54.30%, 71.40% and 22.90%, and within ±30% was 81.40%, 88.60%,74.30%, respectively. The differences among R0 LVEF, R2 LVEF and GBPI LVEF were statistically significant (P<0.05), while between R1 LVEF and GBPI LVEF was not (P>0.05). Conclusion The formula R1 of ECToolbox software is most applicable in measuring LVEF with gated myocardial imaging.

To study the effects of the extract of fungal elicitor, AgNO3, MeJA and yeast on the growth and content of secondary metabolites of adventitious roots in Tripterygium wilfordii. The above elicitors were supplemented to the medium, the growth and the content of secondary metabolites were measured. When the medium was supplemented with the elicitor Glomerella cingulata or Collectotrichum gloeosporioides, the content of triptolide was increased by 2.24 and 1.93-fold, the alkaloids content was increased by 2.02 and 2.07-fold, respectively. The optimal concentration of G. cingulata was 50 μg/mL for accumulation of triptolide, alkaloids and for the growth of adventitious roots. AgNO3 inhibited the growth of adventitious roots and the accumulation of the alkaloids, whereas it (at 25 μmol/L) increased the accumulation of triptolide by 1.71-fold compared to the control. The growth of adventitious roots, the contents of triptolide and alkaloids were increased 1.04, 1.64 and 2.12-folds, respectively when MeJA was at 50 μmol/L. When the concentration of yeast reached 2 g/L, the content of triptolide increased 1.48-folds. This research demonstrated that supplementation of AgNO3 and yeast enhanced the biosynthesis of triptolide in adventitious roots and the synergism of G. cingulata and MeJA could promote the biosynthesis of both triptolide and alkaloids.
