Abstract Objective: Emergence delirium is a common complication in children. Recorded mother’s voice, as a non-pharmacological measure, is increasingly used to prevent the emergence of delirium in pediatric patients, but sufficient evidence is still needed to prove its efficacy. Methods: Embase, PubMed, Cochrane Library, Web of Science, CINAHL, and Sinomed databases were searched for randomized controlled trials exploring the efficacy of recorded mother’s voice in preventing the emergence of delirium in pediatric patients undergoing general anesthesia. The original data were pooled for the meta-analysis with Review Manager 5.4.1. This study was conducted based on the Cochrane Review Methods. Results: Eight studies with 724 children were included in the analysis. Recorded mother’s voice reduced the incidence of emergence delirium when compared with either no voice (RR: 0.45; [95 % CI, 0.34 - 0.61]; p < 0.01; I2 = 7 %) or stranger’s voice (RR: 0.51; [95 % CI, 0.28 - 0.91]; p = 0.02; I2 = 38 %) without increasing other untoward reactions. In addition, it shortened the post-anesthesia care unit stay time when compared with no voice (MD = -5.64; [95 % CI, -8.43 to -2.58]; p < 0.01, I2 = 0 %), but not stranger’s voice (MD = -1.23; [95 % CI, -3.08 to 0.63]; p = 0.19, I2 = 0 %). It also shortened the extubation time and reduced the incidence of postoperative rescue analgesia. Conclusion: The current analysis indicated that recorded mother’s voices could reduce the incidence of emergency delirium, shorten post-anesthesia care unit stay time and extubation time, and decrease the incidence of postoperative rescue analgesia in children.

Abstract As an alternative type of tea product, tartary buckwheat tea (TBT) has become popular in the current market because of its rich taste, natural healthiness and convenience of use. Because sensory evaluation is easily affected by the individual differences and external factors that affect human assessors, the present study used intelligent sensory systems (electronic nose, electronic tongue and electronic eye) to analyze different types of TBT to establish a scientific basis for its quality characteristics. Results showed that obvious differences in color, aroma and taste were found among the different types of teas. The taste differences in the TBT were mainly acquired by the CTS sensor (saltiness) and ANS sensor (sweetness), with the greatest number of volatile substance was detected in the whole plant tea. Overall, intelligent sensory technology could accurately evaluate TBT thus providing the capability to meet the needs of different types of consumers and of different occasions.

ABSTRACT The present study describes the impact of chrysosplenetin, in the absence and presence of artemisinin, on in vitro breast cancer resistance protein-mediated transport activity in Caco-2 cell monolayers using aristolochic acid I as a specific probe substrate. We observed that novobiocin, a known breast cancer resistance protein active inhibitor, increased Papp (AP-BL) of aristolochic acid I 3.13 fold (p < 0.05) but had no effect on Papp (BL-AP). Efflux ratio (PBA/PAB) declined 4.44 fold (p < 0.05). Novobiocin, consequently, showed a direct facilitation on the uptake of AAI instead of its excretion. Oppositely, both artemisinin and chrysosplenetin alone at dose of 10 µM significantly decreased Papp (BL-AP) instead of Papp (AP-BL). Chrysosplenetin alone attenuated the efflux ratio, which was suggestive of being as a potential breast cancer resistance protein suppressant. Oddly, Papp (BL-AP) as well as efflux ratio were respectively enhanced 2.52 and 2.58 fold (p < 0.05), when co-used with artemisinin and chrysosplenetin in ratio of 1:2. The potential reason remains unclear; it might be relative to binding sites competition between artemisinin and chrysosplenetin or the homodimer/oligomer formation of breast cancer resistance protein bridged by disulfide bonds, leading to an altered in vitro breast cancer resistance protein-mediated efflux transport function.

ABSTRACT Our previous work revealed that chrysosplenetin in combination with artemisinin inhibited in vivo P-glycoprotein (P-gp, one of classic multi-drug resistance proteins) mediated digoxin transportation activity by reversing the upregulated P-gp/Mdr1 mRNA expression levels by artemisinin. Therefore, chrysosplenetin might be a potential artemisinin-resistance reversal agent as a P-gp inhibitor. But it still remains unknown if chrysosplenetin has an impact on another pivotal multi-drug resistance protein, breast cancer resistance protein (Bcrp), which is co-expressed with P-gp in apical membrane of intestinal epithelial cell and overlaps some of the substrates and inhibitors. This study, therefore, further addressed the impact of chrysosplenetin, per se or in combination with artemisin, on Bcrp/ABCG2 mRNA expression levels in mice small intestine determined by western blot and real time-quantitative polymerase chain reaction (RT-qPCR) assay. The drugs were intragastrically administrated once per day for 7 days. Novobiocin, a known Bcrp inhibitor, was observed to have no impact on Bcrp/ABCG2 levels with or without artemisinin versus vehicle. Interestingly, artemisinin alone attenuated Bcrp level while chrysosplenetin alone increased it (p < 0.05). Relative mRNA level was significantly decreased when co-used with artemisinin and chrysosplenetin in ratio of 1:2 (p < 0.05). The discrepant results for chrysosplenetin on Bcrp/ABCG2 mRNA expressions might be closely related to the transcriptional or posttranscriptional regulation.

An anisotropic elastic-damage coupled constitutive model for plain concrete is developed, which describes the concrete performance degradation. The damage variable, related to the surface density of micro-cracks and micro-voids, and represented by a second order tensor, is governed by the principal tension strain components. For adequately describing the partial crack opening/closure effect under tension and compression for concrete, a new suitable thermodynamic potential is proposed to express the state equations for modeling the mechanical behaviors. Within the frame-work of thermodynamic potential, concrete strain mechanisms are identified in the proposed anisotropic damage model while each state variable is physically explained and justified. The strain equivalence hypothesis is used for deriving the constitutive equations, which leads to the development of a decoupled algorithm for effective stress computation and damage evolution. Additionally, a detailed numerical algorithm is described and the simulations are shown for uni-axial compression, tension and multi-axial loadings. For verifying the numerical results, a series of experiments on concrete were carried out. Reasonably good agreement between experimental results and the predicted values was observed. The proposed constitutive model can be used to accurately model the concrete behaviors under uni-axial compression, tension and multi-axial loadings. Additionally, the presented work is expected to be very useful in the nonlinear finite element analysis of large-scale concrete structures.
