Objective To explore the clinical application of Narcotrene Ineex( NI)on guieing the usage of propofol combinee with eifferent analgesic erugs at colonoscopy examination,in oreer to evaluate the application ane clinical safety of the eifferent analgesic erugs. Basee on NI guieance,propofol effect-site concentration was aejustee euring colonoscopy. Methods Two huneree ane forty patients with colonoscopy were selectee as our subjects. They were eivieee into 4 groups accoreing to propofol combinee with eifferent analgesic erugs(A group:eezocine + propofol;B Group:fentanyl ane propofol;C Group:Shu fentanyl ane propofol;D groups:saline + propofol)ane each group has 60 cases. At eifferent stages of surgery,NI was control within 56- 65 or 66 - 75 in terms of anesthesia eegree. The life ineices( mean arterial pressure( MAP),heart rate, respiratory rate(RR)ane oxygen saturation( SpO2 )),ineuction time,insert the mirror ane surgical time ane recovery time ane cases with boey movement,the cases of respiratory eepression were recoreee. The analysis of each group of patients with VAS scores ane the total amount of propofol the patients were recoreee at 5 time points(before anesthesia(T1)ane eyelash reflex time(T2),insertee through the anus mirror(T3),when insertee mirror up to the ileocecal(T4)ane the back mirror finish(T5)). Results MAP,heart rate,respiratory rate of patients in four groups at T2,T3 ane T4 time point were eecreasee than that in T1. Comparee with D group, MAP,heart rate,respiratory rate of patients in A,B ane C groups eecreasee at eifferent eegrees(MAP:F within group = 26. 793,P < 0. 05;F interaction = 6. 532,P < 0. 05;F between group = 7. 574,P < 0. 05;Heart rate:F within group = 21. 428,P < 0. 05;F interaction = 6. 316,P < 0. 05;F between group = 5. 431,P < 0. 05;Respiratory rate:F within group = 14. 226,P < 0. 05;F interaction = 5. 531,P < 0. 05;F between group= 7. 986,P < 0. 05). The case of boey movement ane breathing inhibition in A group were 2 ane 2 case,less than that in D group(14,14 cases respectively;P < 0. 01). VAS score ane the total amount of propofol in A,B, C groups were(1. 20 ± 0. 72)points ane(148. 40 ± 10. 53)mg;(1. 88 ± 0. 88)points ane(178. 85 ± 18. 59) mg;(1. 65 ± 0. 74)points ane(166. 68 ± 16. 22)mg,less than that in D group((2. 35 ± 1. 10)points ane (227. 33 ± 28. 66)mg),ane the eifferences was statistically significant( F = 18. 038,177. 399;P < 0. 05).Conclusion During colonoscopy,Narcotrene real-time monitoring of propofol combinee with eifferent analgesics can significantly reeuce the amount of narcotic erugs,shortee recovery time,reeuce the incieence of complications in patients,ane thus enhancing patient comfort .

Objective To analyse the failure reason in transcatheter closure of ventricular septal defect(VSD) ,in order to improve the succeeding rate of occlusive operation on screening VSD patients with echocardiography. Methods Echocardiographic datas were summarized in 50 cases who were failed in VSD occlusion. Results Atrio-ventricular block was occurred in 14 patients,residual shunt was visualized in 13 cases,transcatheter occlusive track could not be set up in 19 cases,arotic valve regurgitation in two cases were screened obviously after occlusive device was released into the intracristal VSD. One case was suffered from cononary heart disease(CAD) and another one was suffered from acute myocardial infarction with ventricular septal perforation. All these patients did not succeed in closure procedure. Conclusions The defect sizes of left and right sides of ventricular septal, structure close to defect must be considered in selecting patients before operation by echocardiography. Occlusion operation should be strictly chosen in cases who were children,or suffered from complex VSD,or senior patients with CAD.

Flavonoids are widely used today in the treatment of ischemic stroke. The therapeutic effects and functions of flavonoids are, therefore, generating more and more interest.

Nitrate is the main form of inorganic nitrogen that crop absorbs, and nitrate transporter 2 (NRT2) is a high affinity transporter using nitrate as a specific substrate. When the available nitrate is limited, the high affinity transport systems are activated and play an important role in the process of nitrate absorption and transport. Most NRT2 cannot transport nitrates alone and require the assistance of a helper protein belonging to nitrate assimilation related family (NAR2) to complete the absorption or transport of nitrates. Crop nitrogen utilization efficiency is affected by environmental conditions, and there are differences between varieties, so it is of great significance to develop varieties with high nitrogen utilization efficiency. Sorghum bicolor has high stress tolerance and is more efficient in soil nitrogen uptake and utilization. The S. bicolor genome database was scanned to systematically analyze the gene structure, chromosomal localization, physicochemical properties, secondary structure and transmembrane domain, signal peptide and subcellular localization, promoter region cis-acting elements, phylogenetic evolution, single nucleotide polymorphism (SNP) recognition and annotation, and selection pressure of the gene family members. Through bioinformatics analysis, 5 NRT2 gene members (designated as SbNRT2-1a, SbNRT2-1b, SbNRT2-2, SbNRT2-3, and SbNRT2-4) and 2 NAR2 gene members (designated as SbNRT3-1 and SbNRT3-2) were identified, the number of which was less than that of foxtail millet. SbNRT2/3 were distributed on 3 chromosomes, and could be divided into four subfamilies. The genetic structure of the same subfamilies was highly similar. The average value of SbNRT2/3 hydrophilicity was positive, indicating that they were all hydrophobic proteins, whereas α-helix and random coil accounted for more than 70% of the total secondary structure. Subcellular localization occurred on plasma membrane, where SbNRT2 proteins did not contain signal peptides, but SbNRT3 proteins contained signal peptides. Further analysis revealed that the number of transmembrane domains of the SbNRT2s family members was greater than 10, while that of the SbNRT3s were 2. There was a close collinearity between NRT2/3s of S. bicolor and Zea mays. Protein domains analysis showed the presence of MFS_1 and NAR2 protein domains, which supported executing high affinity nitrate transport. Phylogenetic tree analysis showed that SbNRT2/3 were more closely related to those of Z. mays and Setaria italic. Analysis of gene promoter cis-acting elements indicated that the promoter region of SbNRT2/3 had several plant hormones and stress response elements, which might respond to growth and environmental cues. Gene expression heat map showed that SbNRT2-3 and SbNRT3-1 were induced by nitrate in the root and stem, respectively, and SbNRT2-4 and SbNRT2-3 were induced by low nitrogen in the root and stem. Non-synonymous SNP variants were found in SbNRT2-4 and SbNRT2-1a. Selection pressure analysis showed that the SbNRT2/3 were subject to purification and selection during evolution. The expression of SbNRT2/3 gene and the effect of aphid infection were consistent with the expression analysis results of genes in different tissues, and SbNRT2-1b and SbNRT3-1 were significantly expressed in the roots of aphid lines 5-27sug, and the expression levels of SbNRT2-3, SbNRT2-4 and SbNRT3-2 were significantly reduced in sorghum aphid infested leaves. Overall, genome-wide identification, expression and DNA variation analysis of NRT2/3 gene family of Sorghum bicolor provided a basis for elucidating the high efficiency of sorghum in nitrogen utilization.
