Objective We used polysomnography (PSG) monitoring and neuropsychological scales to explore the characteristics of coronavirus disease-2019 (COVID-19) patients diagnosed with post-traumatic stress disorder (PTSD) in Wuhan, two years after the onset of the COVID-19 pandemic.Methods A total of 42 patients in the Sleep Medicine Center were diagnosed with insomnia between December 2021 and May 2022; they were divided into the PTSD group (patients with PTSD diagnosed with insomnia after COVID-19 infection) and the non-PTSD group (patients with insomnia without PTSD). A healthy control group was simultaneously included.Results The PTSD group was more significant than the non-PTSD group in partial manifestations of sleep disorders, neuropsychological clinical symptoms, and partial PSG data. Patients with different COVID-19 subtypes showed significant differences in the course of disease, sleep disorders, neuropsychological clinical symptoms, relevant scale scores, and PSG data analysis.Conclusion The emotional anxiety and depression of COVID-19 patients diagnosed with PTSD two years after the COVID-19 pandemic in Wuhan are more significant, and will not be self-alleviated with the passage of time. It is necessary to continue to pay attention to the PTSD symptoms and sleep psychology of COVID-19 infected patients, and take appropriate measures. Patients with severe and critical COVID-19 have more severe sleep and mental disorders, and there is a significant correlation between the duration of the disease and the severity of mental and mental disorders and sleep disorders after recovery.

The purpose of this study was to investigate the effects of micronutrient supplementation on the growth of preschool children in China. A double-blind, placebo-controlled trial was conducted on 156 growth retarded preschool children who were randomly assigned to the following five groups : supplemental control (S-control; n=28); zinc supplementation (+Zn; 3.5mg Zn/day, n=34); zinc and calcium supplementation (+ZnCa; 3.5mg Zn + 250mg Ca/day, n=37); zinc, calcium and vitamin A supplementation (+ZnCaVA; 3.5mgZn + 250mgCa + 200gVA/day, n=28); and calcium and vitamin A supplementation (+CaVA; 250mgCa + 200gVA/day, n=29). Another 34 children of normal height were selected as a normal control (N-control). Supplementation continued for twelve months. After supplementation, the height gains in the +Zn group (7.84cm per year) and the +ZnCa group (7.70 cm per year) were significantly higher than that in the S-control group (6.74 cm per year, P<0.05). The weight gain in the +ZnCaVA group (2.55kg per year) and the +CaVA group (2.57 kg per year) was also significantly higher than that in the S-control group (2.19 kg per year, P<0.05). The average number of days of illness in each group taking supplements was lower than that in the S-control group (13 days per year compared with 23 days per year). No significant differences in bone maturity were observed between the groups. In conclusion, in this study Zinc and Zinc + Calcium supplementation improved the height gain, and vitamin A improved the weight gain, in growth retarded preschool children, but these supplements did not affect the maturity of bone. Micronutrient supplementation also lowered the morbidity of these children.

Neurotoxicity of acrylonitrile evaluated by manganese enhanced magnetic resonance imaging
Ying Li,Lihong Mei,Jinwei Qiang,Chi-Shing Zee,Xiuju Li,Junhua Liu 대한독성 유전단백체 학회 2015 Molecular & cellular toxicology Vol.11 No.3
Acrylonitrile (ACN), a chemical compound commonly used to manufacture plastics, has been found in drin king water and as a pollutant in the air. Exposure to high levels of ACN leads to brain lesions via oxidative stress-induced injury. To date, there is no non-invasive method of examining brain lesions. We determined if manganese-enhanced magnetic resonance imaging (MEMRI) can be used to detect brain lesions in ACN-treated rats by exploiting the binding properties of manganese to the enzymes manganesesuperoxide dismutase (Mn-SOD) and glutamine synthetase (GS). Rats exposed to low, mid, and high doses of ACN over 7 days were subjected to MEMRI on the eighth day. Contrast enhancement of the brain decreased in ACN-treated rats, along with marked decreases in Mn-SOD and GS activities, particularly in mid- and high-ACN treated rats. Our study indicates that MEMRI may be a potential non-invasive method of detecting ACN-induced oxidative damage.
