Background: Intraoperative hypercapnia reduces the time to emergence from volatile anesthetics, but few clinical studies have explored the effect of hypercapnia on the emergence time from intravenous (IV) anesthesia. We investigated the effect of inducing mild hypercapnia during the recovery period on the emergence time after total IV anesthesia (TIVA). Methods: Adult patients undergoing transurethral lithotripsy under TIVA were randomly allocated to normocapnia group (end-tidal carbon dioxide [ETCO2] 35–40 mmHg) or mild hypercapnia group (ETCO2 50-55 mmHg) during the recovery period. The primary outcome was the extubation time. The spontaneous breathing-onset time, voluntary eye-opening time, and hemodynamic data were collected. Changes in the cerebral blood flow velocity in the middle cerebral artery were assessed using transcranial Doppler ultrasound. Results: In total, 164 patients completed the study. The extubation time was significantly shorter in the mild hypercapnia (13.9 ± 5.9 min, P = 0.024) than in the normocapnia group (16.3 ± 7.6 min). A similar reduction was observed in spontaneous breathing-onset time (P = 0.021) and voluntary eye-opening time (P = 0.008). Multiple linear regression analysis revealed that the adjusted ETCO2 level was a negative predictor of extubation time. Middle cerebral artery blood flow velocity was significantly increased after ETCO2 adjustment for mild hypercapnia, which rapidly returned to baseline, without any adverse reactions, within 20 min after extubation. Conclusions Mild hypercapnia during the recovery period significantly reduces the extubation time after TIVA. Increased ETCO2 levels can potentially enhance rapid recovery from IV anesthesia.

The early response of plant auxin gene family Aux/IAA (auxin/indole-3-acetic acid) and its interaction with auxin response factor (ARF) are important pattern to regulate plant growth and development. This work identified 28 StoIAA and 24 StoARF members based on the whole genome data of the medicinal plant Senna tora L., which were classified into 10 and 8 subfamilies, respectively. Phylogenetic tree and collinearity analysis showed that S. tora has close evolutionary relationship with the IAA and ARF homologous genes of Glycine max, Medicago truncatula, and the segment duplication events dominate the expansion of StoIAA and StoARF. Gene structure analysis showed that the vast majority of StoIAA and StoARF contain characteristic conserved domain. Transcriptome data showed that StoIAAs and StoARFs were expressed in leaves, roots and seeds, some members had tissue specific expression. The StoIAA and StoARF promoter region most contain functional elements related to stress response, growth and development, hormone induction and secondary metabolism. In addition, gene expression analysis showed that many StoIAAs and StoARFs can quickly respond to drought and salt stress and exhibited same expression patterns under both stress condition. The yeast two-hybrid experiment confirmed that StoARF8 and StoARF10 exhibit varying degrees of interaction with multiple StoIAA proteins, respectively. The above results provide a basis for further biological functional analysis of the Aux/IAA and ARF gene family of S. tora.

Objective To noninvasively predict isocitrate dehydrogenase(IDH)status of glioma via combining imaging and clini-cal features before surgery,so as to provide basis for individualized clinical treatment decision.Methods A total of 47 patients with glioma confirmed by pathological and molecular genetic tests were included,including 20 with IDH mutant type and 27 with IDH wild type.After diffusion tensor imaging(DTI)scanning,fractional anisotropy(FA)and mean diffusivity(MD)values of tumor paren-chyma were calculated.Combining DTI parameters with MRI morphological features of tumor,blood neutrophil/lymphocyte ratio(NLR)and patient's age,binary logistic regression model was established to effectively predict IDH status of glioma patients before surgery.Results There were significant differences in FAmean/FANAWM,MDmin,NLR,tumor location and age between IDH mutant type and IDH wild type groups(P<0.05).The binary logistic regression model concluding,FAmean/FANAWM,MDmin,cystic degeneration,NLR and age,predicted IDH status of glioma with area under the curve(AUC)of 0.961 and 95%confidence interval(CI)of 0.914-1.00.Conclusion The regression model established via combining DTI,MRI morphological features and blood NLR has great performance in classifying IDH status of glioma,and can help predict IDH status noninvasively before surgery,so as to assist clinical individualized treatment.

ObjectiveTo investigate the effect of Yiqi Tongxin formula （YQTM） on liver inflammation in apolipoprotein E^-∕- （ApoE^-∕-） mice by regulating the nuclear transcription factor-κB （NF-κB）/NOD-like receptor protein 3 （NLRP3） signaling pathway. MethodForty ApoE^-∕- mice were randomly divided into a model group， an atorvastatin group （positive drug group）， and low-， medium-， and high-dose YQTM groups （0.39， 0.78， 1.56 g·kg^-1）. Each drug administration group was given the corresponding concentration of the drug by gavage on the basis of high-fat feeding for 12 consecutive weeks. Eight C57BL/6J mice were used as a blank group and fed with normal chow. After 12 weeks， oil red O staining and Masson staining were used to observe the aortic lesions in mice and to determine whether the modeling was successful. Oil red O staining was used to observe the lipidosis in the livers of mice. Hematoxylin-eosin （HE） staining was used to observe the tissue lesions in the livers of mice. Masson staining was used to observe the distribution of collagen fibers in the livers of mice. Enzyme markers were used to detect the total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein （LDL-C）， aspartate aminotransferase （AST）， and alanine aminotransferase （ALT） in mouse serum， as well as total cholesterol （TC） and triglyceride （TG） in the liver. Interleukin-1β （IL-1β） and IL-18 were detected in mouse liver by enzyme-linked immunosorbent assay （ELISA）. Immunohistochemistry （IHC） was utilized to observe the expression regions of NF-κB and NLRP3 in the livers of mice. Western blot was employed to detect the protein expression levels of NF-κB， NF-κB inhibitory protein （IκB）， IκB kinase β （IKKβ）， phosphorylated NF-κB （p-NF-κB）， phosphorylated IκB （p-IκB）， phosphorylated IKK β （p-IKKβ）， NLRP3， and Caspase-1 in the livers of mice. ResultCompared with the blank group， the model group showed severe aortic lipidosis， and the intracellular fat droplets in the livers aggregated in large quantities. The cytoplasm was filled with fat vacuoles（P<0.01）. The serum levels of TG， TC， LDL-C， AST， and ALT were significantly elevated in the mice（P<0.01）. TG and TC levels were elevated in the liver（P<0.01）. The levels of IL-1β and IL-18 in liver tissue， as well as the protein expression levels of NF-κB， IκB， IKKβ， p-NF-κB， p-IκB， p-IKKβ， NLRP3， and Caspase-1 in the liver were significantly elevated（P<0.01）. Compared with the model group， the aortic arch plaques of mice in each YQTM group were attenuated， and the fat aggregation in the liver was reduced. The inflammatory cell infiltration was alleviated（P<0.05，P<0.01）. The serum levels of TG， TC， LDL-C， AST， and ALT were significantly reduced（P<0.05，P<0.01）. TG and TC levels in the liver were reduced. The IL-1β and IL-18 levels in liver tissue， as well as protein expression levels of NF-κB， IκB， IKKβ， p-NF-κB， p-IκB， p-IKKβ， NLRP3， and Caspase-1 in the liver were significantly reduced（P<0.05，P<0.01）. ConclusionThe intervention mechanism of YQTM on liver inflammation in ApoE^-∕- mice may be related to the down-regulation of the NF-κB/NLRP3 signaling pathway.

OBJECTIVE To investigate the effects of Yiqi tongmai formula on atherosclerosis （AS） in ApoE－/－ mice and its mechanism. METHODS Forty ApoE－/－ mice were randomly divided into model group， positive control group [atorvastatin calcium， 2.6 mg/（kg·d）]， and low-dose， medium-dose and high-dose groups of Yiqi tongmai formula [0.46， 0.91， 1.82 g/（kg·d）， by raw material]， with 8 mice in each group. Eight C57BL/6J mice were selected as the normal group. Except for the normal group， the other groups were given a high-lipid diet and relevant drug or normal saline intragastrically， once a day， for 12 consecutive weeks. After the last medication， the serum levels of total cholesterol （TC）， triglyceride （TG）， low-density lipoprotein cholesterol （LDL-C） and high-density lipoprotein cholesterol （HDL-C） as well as the contents of tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β） and monocyte chemoattractant protein-1 （MCP-1） were measured in mice. The proportion of aortic plaque area in each group of mice was detected and calculated， and the pathological morphological changes of the aortic sinus were observed； the protein phosphorylation levels of aortic phosphoinositide 3-kinase （PI3K）， protein kinase B （aka Akt） and mammalian target of rapamycin （mTOR） were examined. RESULTS Compared with the model group， the serum levels of TC， TG and LDL-C and the contents of TNF-α， IL-1β and MCP-1 （including low-dose group） were decreased significantly in medium-dose and high-dose groups of Yiqi tongmai formula， while the content of HDL-C in high-dose group was increased significantly （P＜0.05 or P＜0.01）； aortic plaques of the mice were reduced in Yiqi tongmai formula groups to different extents， and pathological changes such as lipid deposition and inflammatory cell infiltration were relieved to different extents； the proportion of aortic plaque area， the protein phosphorylation levels of PI3K， Akt and mTOR in aortic tissue were significantly reduced in medium-dose and high-dose groups of Yiqi tongmai formula （P＜0.05 or P＜0.01）. CONCLUSIONS Yiqi tongmai formula can improve lipid metabolism， reduce inflammatory response， and delay plaque development in AS mice. Its effect may be related to the inhibition of PI3K/Akt/mTOR signaling pathway activation.
