ObjectiveTo study the prevalence of depression, anxiety, and insomnia among social workers during the prolonged battle against the COVID-19 pandemic and explore the associated risk factors.MethodsUsing a stratified cluster sampling method, we selected all social workers in the five streets of Chaoyang District, Beijing(Jiuxianqiao, Wangjing, Taiyanggong, Shibalidian, Sunhe) from November 2021 to March 2022 as the study population(social worker group), and the frontline medical staffs(medical professional group) of the same age range of the corresponding community hospitals of the same five streets, and the community residents(resident group) as the control population. The ratio of the social worker group, medical professional group, and resident group was 1∶1∶1. The Sojump platform was used to send electronic questionnaires to the wechat groups of social workers, healthcare workers, and community residents to carry out the survey. The screen positive rates for anxiety, depression, and sleep disorders were compared among the 3 groups. Multifactorial Logistic regression and decision tree were used to analyze the influencing factors of anxiety, depression, and sleep disorders among social workers.ResultsA total of 954 questionnaires were collected, of which 62 were disqualified and excluded. Finally, 892 valid questionnaires(93.5%) were included for data analysis. Among them, there were 372 questionnaires(41.7%) from the social worker group, 262(29.4%) from the medical professional group, and 258(28.9%) from the resident group. The prevalences of anxiety, depression, and sleep disorders among social workers group were found to be 15.3%, 22.0%, and 48.1%, respectively, which were significantly higher than those in the medical professional group(7.6%, 10.3%, and 30.5%) and the resident group(7.0%, 8.5%, and 29.5%), all P < 0.001. Multiple Logistic regression showed that family burden(OR=1.80, 95% CI: 1.09-2.96) and Chinese perceived stress scale(CPSS) score(OR=1.34, 95% CI: 1.24-1.45) were independent influencing factors for anxiety among social workers; CPSS score(OR=1.29, 95% CI: 1.20-1.39) and social support rating scale(SSRS) score(OR=0.96, 95% CI: 0.92-1.00) were independent influencing factors for depression among social workers; family history of mental illness(OR=4.91, 95% CI: 1.27-18.94), CPSS score(OR=1.20, 95% CI: 1.14-1.27), and SSRS score(OR=0.95, 95% CI: 0.91-0.98) were independent influencing factors for sleep disorders among social workers. The results of decision tree analysis were consistent with those of multiple Logistic regression analysis. Family burden, CPSS score, and SSRS score were important variables affecting the mental health of social workers, among which CPSS score was strongly associated with anxiety, depression, and sleep disorders among social workers.ConclusionsSocial workers exhibited significant levels of anxiety, depression, and sleep disorders during the long-term pandemic prevention, with CPSS being the most significant influencing factor.

Background Postoperative cognitive dysfunction (POCD) is one of the major causes of increased postoperative morbidity and mortality in patients. The inflammatory response and ferroptosis are the principal hypotheses of the mechanism of POCD development. But the mechanism of electroacupuncture to improve learning and memory function in POCD patients is unclear. Objective To observe the effect of electroacupuncture on learning, memory, inflammatory cytokines and ferroptosis of hippocampal neurons in aged rats with POCD, so as to explore the mechanism of improving POCD by electroacupuncture. Methods From January 2022 to February 2023, 72 SD rats aged 18 to 20 months were selected and divided into 3 groups according to random number table method of control group (n=24) , model group (n=24) and electroacupuncture group (n=24) . According to the observation time points of 3 and 7 days postoperative, the rats in each group were divided into 2 the subgroups (3 d postoperative subgroup in control group, 7 d postoperative subgroup in control group, 3 d postoperative subgroup in model group, 7 d postoperative subgroup in model group, 3 d postoperative subgroup in electroacupuncture group, 7 d postoperative subgroup in electroacupuncture group) , with 12 rats in each group. POCD model was established by exploratory laparotomy, and Baihui and Neiguan points were stimulated by electroacupuncture. The Morris water maze device was used to detect the behavioral performance of rats. The contents of interleukin (IL) 6, IL-10, tumor necrosis factor alpha (TNF-α) in serum and hippocampus were detected by enzyme-linked immunosorbent assay, and lipid peroxides (LPO) and Fe2+ in hippocampus were detected. The protein expression levels of acyl coenzyme A synthetase long-chain family member 4 (ACSL4) , ferritin heavy chain 1 (FTH1) and lysophosphatidylcholine acyltransferase-3 (LPCAT3) in hippocampus were detected by Western Blotting. The ultrastructure of hippocampal neurons was observed by transmission electron microscopy. Results Group and time had no interaction effect on the escape latency of cognitive function training at 3 and 7 d postoperatively (Pinteraction>0.05) , the main effect of training time on the escape latency of cognitive function training was significant (Ptime0.05) . The escape latency of 3 d postoperative subgroup in model group was higher than that of 3 d postoperative subgroup in control group and 3 d postoperative subgroup in electroacupuncture group. The frequency of crossing platform and target quadrant residence time of 3 d postoperative subgroup in model group were lower than those of 3 d postoperative subgroup in control group and 3 d postoperative subgroup in electroacupuncture group; the frequency of crossing platform in 3 d postoperative subgroup in electroacupuncture group was lower than that of 3 d postoperative subgroup in control group (P

The positional accuracy of satellite imagery is essential for remote sensing cameras. However, vibrations and temperature changes during launch and operation can alter the exterior orientation parameters of remote sensing cameras, significantly reducing image positional accuracy. To address this issue, this article proposes an exterior orientation parameter variation real-time monitoring system (EOPV-RTMS). This system employs lasers to establish a full-link active optical monitoring path, which is free from time and space constraints. By simultaneously receiving star and laser signals with the star tracker, the system monitors changes in the exterior orientation parameters of the remote sensing camera in real time. Based on the in-orbit calibration geometric model, a new theoretical model and process for the calibration of exterior orientation parameters are proposed, and the accuracy and effectiveness of the system design are verified by ground experiments. The results indicate that, under the condition of a centroid extraction error of 0.1 pixel for the star tracker, the EOPV-RTMS achieves a measurement accuracy of up to 0.6″(3σ) for a single image. Displacement variation experiments validate that the measurement error of the system deviates by at most 0.05″ from the theoretical calculation results. The proposed EOPV-RTMS provides a new design solution for improving in-orbit calibration technology and image positional accuracy. [ABSTRACT FROM AUTHOR]

Herein, we have described a novel organocatalytic approach to access biologically important dihydropyridin-2-ones in a one-pot way with generally high yields (up to 99%) and excellent enantioselectivities (up to 99% ee). This reaction proceeded via a new dual activation mode, including in situ-generated α,β-unsaturated acylazoliums and 4-dimethylaminopyridinium salts that underwent a Michael addition/1,4-H migration/lactamization sequence. The base-triggered 4-dimethylaminopyridinium ylide formation pathway over the competing substitution reaction pathway of vicinal haloamines is noteworthy. [ABSTRACT FROM AUTHOR]

The control of the speed of terahertz waves is always a challenge since the bandgap of most optical materials is much larger beyond meV with subtle nonlinear susceptibility. Moiré metasurfaces are shown to exhibit wide tunable optical properties and extraordinary physical phenomena at specific commensurate angles. These can be achieved by a careful design of the metasurface to manipulate terahertz slow light. Herein, we demonstrate a triple layer Moiré metasurface with a distinct electromagnetically induced transparency (EIT) phenomenon at commensurate angles. The proposed metasurface is composed of an intrinsic square lattice embedded into another Moiré photonic superlattice made of twisted square lattice at commensurate angles of 10.39° and 7.63°. The coupling between adjacent meta-atoms on the combined metasurface leads to destructive interference of dual trapped lattice modes, which results in a transparency window at the terahertz band. A maximum group delay of 9.76 ps is found at the transparent window of 0.84 THz when the commensurate angle is 10.39°. When the commensurate angle reduces to 7.63°, the transparency window shifts to 0.57 THz with a 5.96 ps group delay. The coupled Lorentz oscillator model indicates that the nonlinear optical susceptibility at transparency windows is above zero. Our results create an approach to tune the EIT as well as slow light in the terahertz band. Our device can have potential applications in terahertz signal processing and storage.
