Restlessness extent, incidence,time of eye oPening after calling, fully awaking time, extubation time, the time of transferring out of CICU and VAS scores,were also recorded. Results From t0 to t2-t5 ,SBP in D grouP was decreased from (114. 2±10. 5) mmHg to (107. 2±10. 3) -(105. 3±11. 3) mmHg,DBP decreased from (61. 3±9. 2) mmHg to (58. 8±7. 8) -(57. 3±6. 3) mmHg,and HR gradually decreased from (95. 2±15. 7) time·min-1 to (85. 7±13. 7)-(83. 3±12. 6) time·min-1,with significant differences (P<0. 05). ComPared with C grouP,SBP and DBP at t2-t5 were decreased significantly (P<0. 01),and HR at t1-t5 decreased significantly (P<0. 01). OVerall incidence of agitation was significantly higher in grouP C than in grouP D (48. 3%vs. 16. 7%,P<0. 01). Incidence of moderate and seVere agitation were significantly higher in grouP C than in grouP D (18. 3%vs. 6. 7%,and 20%vs. 1. 7%,resPectiVely,P<0. 01). In grouP D,time of eye oPening after calling,fully awaking time,extubation time,and the time of transferring out of CICU were Prolonged,without significant difference as comPared with grouP C (P>0. 05). VAS at 30 min after extubation was significantly higher in grouP C than in grouP D(4. 7±0. 7 vs. 2. 4±0. 6,P<0. 05). Conclusion Injection of Dex with loading dose (1 μg·kg-1) and intraoPeratiVe infusion of maintenance dose of 0. 5 μg·kg-1·h-1 in children with congenital heart disease undergoing fast_track anesthesia and whole Video_assisted thoracoscoPic surgery could be conduciVe to maintain hemodynamic stability, reduce restlessness occurrence, enhance security during awakening Process, and alleViate Post_oPeratiVe Pain.

Abstract: Total RNA was isolated from Siraitia grosvenorii fruit by the method of modified Trizol, according to S. grosvenorii fruit characteristics of rich phenols, polysaccharide, oil and proteins. The OD260/280, OD260/230, RNA integrity (RIN) and yield of the total RNA with this method were 2.01, 2.02, 9.50 and 260 mirog.g-1, respectively. The open reading frame (ORF) of dehydroascorbate reductase (DHAR), named as SgDHAR, was cloned by rapid amplification of cDNA ends (RACE) and RT-PCR method from S. grosvenorii. The GenBank accession number for this gene is KC907731. The SgDHAR gene contains a full-length cDNA of 1,252 bp including ORF of 819 bp and encodes a predicted protein of 272 amino acids. The molecular mass is 30.217 7 kD and the isoelectric point is 8.76. Homology comparison showed that it shared 87% nucleotide sequence homology with Cucumis sativus. Expression patterns using qRT-PCR analysis showed that SgDHAR was mainly expressed in fruit and stem, followed by flower, and was lowest in root, while the expression level was 6.83 times in triploid. T than that in diploid. Therefore, SgDHAR gene may be involved in abortion of triploid seedless S. grosvenorii.

Objective To investigate the characteristics of liver enzyme between acute graft-versushost disease (aGVHD) and non-aGVHD groups after allogeneic hematopoietie stem cell transplantation (allo-HSCT). Methods The liver enzyme data of patients with or without aGVHD was analyzed. Results Among the 371 patients, 158 developed aGVHD(41.6%) with a median time of 29. 5 d. In non-aGVHD group, the median elevating times of ALT, AST, GGT, LDH were all ≤ 20 d after transplantation, which were significantly earlier than those of aGVHD group. The peak value of AST was much higher in aGVHD group, but the remaining liver enzyme showed no significant difference. In aGVHD group, the duration of AST, GGT and LDH was significantly longer than the non-occurrence of aGVHD group, but ALT and ALP showed no difference in duration. In ALT, AST, ALP and LDH elevating group, the occurrence rate of aGVHD was significantly higher, but only ALT and LDH elevation could enter logistic regression model. The sensitivity and veracity of ALT or LDH elevating only were not very good for the diagnosis of aGVHD, but if ALT and LDH beth elevated after day 24 and persisted more than 22 d, the sensitivity and veracity were better. Conclusions The change of liver enzyme is common in allo-HSCT and associates with the occurrence of aGVHD, and the liver enzyme elevating only may not be a good diagnostic index of aGVHD. If the dynamic characteristics of liver enzyme is taken into account and the effect of drug-induced liver injury could be excluded, the elevation of liver enzyme still have the diagnostic value of aGVHD.
