22. The Effect of EF on PM Performance in School-Age Children

Author

Ren, Zhi, Liang, Xiao, Sun, Fanhui, and Wang, Lijuan

Abstract

Prospective memory (PM) is vital for children to live independently. Theoretical and empirical evidence has shown that executive function (EF) plays an important role in children's PM. However, there is no EF training for the PM of school-age children. Therefore, a 4-week EF training programme was conducted in this study to investigate the transfer effects of training on event-based PM in 8- to 12-year-old children. Children were randomly assigned to the EF training or control groups. The results revealed that EF training was more effective in enhancing children's PM performance; in particular, there was a transfer effect of EF. Further findings suggested that this transfer effect was observed only in older children, which supported the magnification account that those with strong EF abilities profit most. Moreover, the benefits of training were predicted by inhibition and switching ability. Altogether, EF training has the potential to improve children's PM, especially for children with better EF.

Abstract

Objective To explore the clinical application of quantitative electroencephalography (qEEG) in predicting the early prognosis of acute ischemic stroke after mechanical thrombectomy. Methods A total of 71 patients who underwent acute ischemic stroke mechanical thrombectomy from April 2021 to September 2022 were enrolled in He'nan Provincial People's Hospital, all of them performed qEEG after surgery. Modified Rankin Scale (mRS) was used to evaluate the prognosis on the 90 d after the surgery. Univariate and multivariate backward Logistic regression analyses were used to screen risk factors for prognosis in acute ischemic stroke after mechanical thrombectomy. Receiver operating characteristic (ROC) curve was used to predict the value of qEEG for the prognosis of neural function. Results Patients in dismal prognosis group (mRS score 3-5, n = 28) had higher NIHSS score at admission (t = 2.686, P = 0.009), higher proportion of thrombectomy performed more than 3 times (χ2 = 4.201, P = 0.040), higher values of DTABR on the affected side (t = 2.183, P = 0.032), higher ratio of DTABR on affected side/ unaffected side (t = 6.230, P = 0.000), and higher proportion of immediately Thrombolysis in Cerebral Infarction (TICI) < 2b after surgery (χ2 = 5.420, P = 0.020) compared to favorable prognosis group (mRS score 0-2, n = 43). Logistic regression analysis showed higher NIHSS score at admission (OR = 1.542, 95%CI: 1.368-1.725；P = 0.012), DTABR on affected side/unaffected side (OR = 3.428, 95%CI: 2.673-7.314; P = 0.008), percent alpha variability (PAV) grade Ⅱ (OR = 2.983, 95%CI: 2.625-4.682; P = 0.003) and grade Ⅲ (OR = 4.088, 95%CI: 3.825-5.349; P = 0.002), amplitude electroencephalography (aEEG) grade Ⅱ (OR = 2.536, 95%CI: 1.942-5.287; P = 0.005) and grade Ⅲ (OR = 3.924, 95%CI: 2.012-6.378; P = 0.003) were risk factors of dismal prognosis in acute ischemic stroke after mechanical thrombectomy. ROC curve showed the area under the curve (AUC) of NIHSS score was 0.676 (95%CI: 0.554-0.782, P = 0.000), DTABR on affected side/unaffected side was 0.887 (95%CI: 0.789-0.950, P = 0.000), the PAV was 0.760 (95%CI: 0.643-0.853, P = 0.000), aEEG was 0.778 (95%CI: 0.664-0.868, P = 0.000), and the combined indicators classification was 0.943 (95%CI: 0.861-0.984, P = 0.000). Among them, the predictive power of the combined indicators is higher than that of the NIHSS score at admission (Z = 4.150, P = 0.000), PAV (Z = 4.006, P = 0.000) and aEEG (Z = 3.462, P = 0.001). Conclusions qEEG is an effective method to predict the early prognosis of acute ischemic stroke after mechanical thrombectomy.

Abstract

As one of the most induced genes in activated macrophages, immune-responsive gene 1 (IRG1) encodes a mitochondrial metabolic enzyme catalysing the production of itaconic acid (ITA). Although ITA has an anti-inflammatory property, the underlying mechanisms are not fully understood. Here we show that ITA is a potent inhibitor of the TET-family DNA dioxygenases. ITA binds to the same site on TET2 as the co-substrate α-ketoglutarate, inhibiting TET2 catalytic activity. Lipopolysaccharide treatment, which induces Irg1 expression and ITA accumulation, inhibits Tet activity in macrophages. Transcriptome analysis reveals that TET2 is a major target of ITA in suppressing lipopolysaccharide-induced genes, including those regulated by the NF-κB and STAT signalling pathways. In vivo, ITA decreases the levels of 5-hydroxymethylcytosine, reduces lipopolysaccharide-induced acute pulmonary oedema as well as lung and liver injury, and protects mice against lethal endotoxaemia, depending on the catalytic activity of Tet2. Our study thus identifies ITA as an immune modulatory metabolite that selectively inhibits TET enzymes to dampen the inflammatory responses.

Abstract

In order to improve the cooperative ability of multiple unmanned combat aircraft vehicle(UCAV) in air combat, a cooperative air combat maneuver decision method based on multi-agent dual delay depth deterministic policy gradient algorithm (MATD3) is proposed. Firstly, the air combat environment is constructed based on the three degree of freedom dynamic model of UCAV, and the action space represented by the change of control quantity is designed based on the pilot’s control mode. Secondly, the design of state space and reward function is optimized to improve the accuracy of maneuvering decision and the safety of maneuvering flight. The relative relationship between friendly aircraft and enemy aircraft is introduced into state space, the continuous reward function is established according to the relative angle, relative distance and other air combat situation factors, and the flight constraints are integrated into the discrete type reward function. Training techniques such as phased training, heuristic guidance, dual exploration mechanism, and alternating freezing game are adopted to improve the convergence speed of the algorithm and the robustness of the maneuvering strategy.Finally, a two-to-one air combat simulation scenario is constructed, and the results show that our two aircraft can show obvious cooperative behavior, which improves the perception and control of air combat situation.
