Background: Influenza A virus (IAV) is a negative-sense RNA virus of the Orthomyxoviridae family and is the etiological agent of a highly contagious acute respiratory disease that can lead to acute lung injury. Objective: To elucidate the molecular mechanisms of IAV infection, an integrative research approach combining gene expression profiling, multinetwork analysis, and in vivo experimental validations was employed. Methods: First, a series of network-based analyses were performed, including protein-protein interaction network construction, weighted gene co-expression network analysis, and subsequent gene set enrichment analysis, to identify the major underlying mechanisms of IAV infection. Following gene expression analysis, core targets, both direct and indirect regulators, were screened. An IAV (H1N1) strain A/PR/8/34-induced acute lung injury mouse model was constructed for in vivo validations. Batch one included two groups to evaluate findings from the multi-network analysis: Mock (n = 10; 5 males and 5 females) and IAV (n = 10; 5 males and 5 females). Batch two included three groups to assess the role of toll-like receptor 3 (TLR3) in IAV infection: Mock (n = 6; 3 males and 3 females), IAV (n = 6; 3 males and 3 females), and TLR3 inhibitor (n = 6; 3 males and 3 females). Body weight was measured on days 0, 3, and 5 after infection. On day 5, lung tissues were collected to assess viral load and histopathological changes. Key targets were examined using enzyme-linked immunosorbent assay, Western blotting, and immunofluorescence staining, both in sera and lung tissues. Results: IAV infection was significantly associated with dysregulation of the immune-inflammation system, such as the LTR, nucle-otide-binding oligomerization domain-(NOD) like receptor, retinoic acid-inducible gene I-like receptor, and nuclear factor kappa-B signaling pathways. Gene set enrichment analysis further indicated that the TLR and necroptosis signaling pathways played crucial roles in the progression of IAV infection (TLR signaling pathway normalized enrichment score = 2.3941, P = 1.00 × 10 ⁻¹⁰; necroptosis normalized enrichment score = 1.9421, P = 6.21 × 10 ⁻⁷). Among the core targets, TLR3 and mixed lineage kinase domain-like protein (MLKL) may regulate gene expression at the transcriptional level (all P < 0.05). In vivo validation using an IAV (PR8) infected acute lung injury mouse model demonstrated increased viral load and lung index, alveolar structural damage, and inflammatory cell infiltration. Immunofluorescence staining exhibited large gaps in Lamin B1 staining and breaches in Emerin signals following IAV-PR8 infection. Expression levels of TLR3, p-receptor-interacting serine/threonine-protein kinase 3 (RIPK3)/RIPK3, and p-mixed lineage kinase domain-like protein (MLKL)/MLKL proteins in lung tissues, as well as proinflammatory factors and mediators in sera, were significantly elevated after IAV infection. Moreover, enhanced neutrophil infiltration (myeloperoxidase) and citrullinated histone H3 (a neutrophil extracellular trap-specific marker), both established indicators of neutrophil extracellular trap formation, were observed. Notably, treatment with a TLR3 inhibitor significantly ameliorated IAV-induced acute lung injury by regulating necroptosis-related targets. Conclusion: Our study provides network-based in vivo evidence that TLR3-receptor-interacting serine/threonine-protein kinase 3-MLKL-mediated necroptosis may underlie IAV-induced acute lung injury and could serve as a potential therapeutic target in severe influenza cases.

Objective:To compare the application effects of the solution-focused nursing model (SFNM) and conventional care in the perioperative care for patients with pelvic fractures.Methods:A retrospective cohort study was conducted to analyze the clinical data of 62 patients with pelvic fractures admitted to the Third Affiliated Hospital of Southern Medical University between February 2023 and July 2023, including 41 males and 21 females, aged 26-63 years [(44.1±15.7)years]. All the patients underwent open or closed reduction and internal fixation. According to different perioperative nursing intervention, 31 patients were treated with conventional care (conventional care group) and 31 with SFNM intervention based on conventional care (SFNM group). A comparative analysis was conducted between the two groups regarding general self-efficacy scale (GSES) score, Barthel index (BI) score, self-rating anxiety scale (SAS) score, and self-rating depression scale (SDS) score preoperatively, at discharge, and at 6 months postoperatively. The excellent-to-good rate of Majeed pelvic function score and nursing satisfaction at the final follow-up and perioperative complication incidence were compared between the two group.Results:All the patients were followed up for 12-15 months [(13.5±0.9)months]. No significant differences were observed between the two groups in GSES, BI, SAS or SDS scores ( P>0.05). At discharge, the GSES and BI scores in the SFNM group were (29.0±3.8)points and (37.4±8.7)points, significantly higher than (20.9±3.0)points and (31.5±12.1)points in the conventional care group ( P<0.05); the SAS and SDS scores were (41.9±5.1)points and (40.6±4.9)points in the SFNM group, significantly lower than (53.7±9.1)points and (42.9±7.5)points in the conventional care group ( P<0.01). At 6 months postoperatively, the SFNM group achieved GSES and BI scores of (34.0±4.0)points and (40.3±9.0)points, significantly higher than (25.2±3.7)points and (35.7±10.5)points in the conventional care group ( P<0.05); the SAS and SDS scores were (45.8±5.0)points and (38.2±3.0)points in the SFNM group, significantly lower than (50.0±8.5)points and (40.7±6.5)points in the conventional care group ( P<0.01). At the final follow-up, the excellent-to-good rate of Majeed pelvic function score was 90% (28/31) in the SFNM group and 87% (27/31) in the conventional care group ( P>0.05). At the final follow-up, nursing satisfaction rate was 100% (31/31) in the SFNM group, significantly higher than 77% (24/31) in the conventional care group ( P<0.05). The perioperative complication rate was 6% (2/31) in the SFNM group, significantly lower than 38% (12/31) in the conventional care group ( P<0.05). Conclusion:Compared with conventional care, perioperative intervention with SFNM for patients with pelvic fractures can enhance self-efficacy and daily living self-care ability, reduce negative emotions such as anxiety and depression, improve nursing satisfaction, and lower the incidence of complications, making it worthy of clinical promotion.

Objective:To analyze the related factors of neurotoxicity induced by oxaliplatin chemotherapy in patients with colorectal cancer and its prevention and treatment strategies.Methods:A total of 300 patients with colorectal cancer treated with oxaliplatin in Zhejiang Cancer Hospital from January 2018 to December 2020 were randomly selected for baseline collection using the convenience sampling method. The occurrence of oxaliplatin-induced peripheral neurotoxicity (OIPN) was statistically analyzed. The factors that affect the occurrence of OIPN were analyzed using univariate analysis.Results:There was a significant difference in OIPN score between patients of different genders, between patients who had different education levels, between patients who had different occupations, and between patients who lived in different long-term residence places ( t = 7.29, 3.39, 2.53, 18.11, all P < 0.05). There was no significant difference in OIPN score between patients adhering to different religion's beliefs, between patients married and not, between patients who lived with and without members, between patients who paid medical costs and not, and between patients who had a previous history of smoking and not ( t = 3.25, 0.37, 0.69, 2.39, 0.15, all P > 0.05). There was a significant difference in OIPN score between patients with different tumor-node-metastasis stages, between patients who received medication via different administration routes, and between patients who received different times of oxaliplatin administration ( t = 8.40, 3.34, 3.49, all P < 0.05). Conclusion:Medical staff should pay attention to the occurrence of OIPN in patients with colorectal cancer treated with oxaliplatin, focus on the patient's factors related to the disease, and take correct and effective coping strategies promptly to reduce the adverse reactions, improve the quality of life, and ensure the therapeutic effect.

Objective: To examine the changes of depressive and anxiety symptoms in school aged children during home confinement and to identify possible influence of learning and lifestyle behaviors on mental health changes. Methods: The population of this study were obtained from the "Tongji Mental Health Cohort". Two primary schools in Wuhan were selected through cluster sampling and students in grade 2-5 were surveyed. This study was divided into two stages. In the first stage (T1=during home learning), a total of 2 588 valid questionnaires were collected. In the second phase (T2=during school learning), 2 424 children were followed up successfully. Combining the results of the depression and anxiety symptoms of the two surveys of children respectively to classify the children s psychological outcomes. Association between home learning and lifestyle behaviors with the change of psychological symptoms in school aged children were estimated by disordered multi classification Logistic regression. Results: The prevalence of depressive and anxiety symptoms were 28.9% and 21.0% in school aged children at T1, 35.6% and 30.6% at T2, respectively. The aggravation and persistence of depressive and anxiety symptoms in children were partly related to their home learning and lifestyle behaviors. Concentration in class（ OR=0.63，95%CI =0.45-0.89）, frequent interaction with teachers ( OR =0.74, 95% CI = 0.57- 0.95 ), participation in physical exercise at home ( OR =0.60, 95% CI =0.41-0.87) was negatively associated with depressive symptoms in children. Time spent on playing video games ( OR =1.15, 95% CI =1.06-1.24) and fear of infection with coronavirus disease 2019 ( OR =1.83, 95% CI =1.39-2.42) were positively associated with anxiety in children. Boys（ OR=0.70， 0.63 ） were more likely to suffer from depression and anxiety symptoms than girls. Conclusion The prevalence of depressive and anxiety symptoms among school aged children increased when they went back to school after home confinement, suggesting more attention are needed for mental health intervention among school aged children.

Objective: To investigate the progression of depressive and anxiety symptoms of children, especially whose parents were frontline workers in the combat of the coronavirus disease 2019 (COVID-19), and to provide evidence for children s mental health promotion. Methods: In June and December 2020, two surveys were conducted among the children in a primary school in Qiaokou District, Wuhan. The questionnaire included demographic information, student learning conditions, and depressive/anxiety symptoms. Results: A total of 963 children completed both surveys. The detection rate of depressive and anxiety symptoms at follow up was significantly higher than that at the baseline survey (depressive symptoms: OR=1.45, 95%CI =1.16-1.83; anxiety symptoms: OR=1.79, 95%CI =1.41-2.28, P <0.01). There was no statistically significant change in depressive/anxiety symptoms among children whose parents were frontline workers compared with those whose parents were not( P >0.05). Girls, lower learning efficiency, and less interaction with teachers in class were risk factors for depressive or anxiety symptoms of children( P < 0.05 ). Conclusion Mental health status of children requires continuous attention. Moreover, timely psychological protection should be given to prevent the occurrence of psychological problems and the further deterioration of psychological problems.

Myocardial ischemia (MI) causes somatic referred pain and sympathetic hyperactivity, and the role of sensory inputs from referred areas in cardiac function and sympathetic hyperactivity remain unclear. Here, in a rat model, we showed that MI not only led to referred mechanical hypersensitivity on the forelimbs and upper back, but also elicited sympathetic sprouting in the skin of the referred area and C8-T6 dorsal root ganglia, and increased cardiac sympathetic tone, indicating sympathetic-sensory coupling. Moreover, intensifying referred hyperalgesic inputs with noxious mechanical, thermal, and electro-stimulation (ES) of the forearm augmented sympathetic hyperactivity and regulated cardiac function, whereas deafferentation of the left brachial plexus diminished sympathoexcitation. Intradermal injection of the α₂ adrenoceptor (α₂AR) antagonist yohimbine and agonist dexmedetomidine in the forearm attenuated the cardiac adjustment by ES. Overall, these findings suggest that sensory inputs from the referred pain area contribute to cardiac functional adjustment via peripheral α₂AR-mediated sympathetic-sensory coupling.

Abstract Children were vulnerable groups in major public health emergencies. In 2020, the coronavirus disease 2019 (COVID-19) pandemic was widespread in the world. The mental health of school age children has become a worldwide concern. Herein, we conducted this review to evaluate the impact of COVID-19 on the mental health of general children and special children with a high risk of psychological problems, focusing on the prevalence of anxiety, depression, and post traumatic stress disorder among school age children in different countries and regions during the COVID-19 epidemic. Considering the susceptibility between individuals and the accessibility of social resources, we further explored the child, family, and social related factors affecting the mental health of school age children. Finally, some suggestions on the construction of children s mental health service system in major public health emergencies were put forward at the national, school family community, and individual levels. Building a safe and reliable child mental health protection network required the joint efforts of all sectors of society.

Objective: To provide a largescale assessment the prevalence of poor vision in 2020 among children and adolescents in Wuhan City, Hubei province and to provide basis for healthy vision promotion. Methods: This crosssectional epidemiological study was conducted among 156 783 students, who lived in Wuhan during the COVID-19 period participated the vision screening through the online applet designed by Wuhan Center for Adolescent Poor Vision Prevetion and Control under the guidance of their guardians between June 19 and July 6, 2020. The demographic information and daily hours spent on various activities in the past week were investigated. The corresponding visual acuity data of students in 2019 before the COVID-19 outbreak was extracted from school vision monitoring records for each semester, which was measured by the experienced eye care professionals. Results: The detection rate of poor vision (51.04%) in 2020 was significantly higher than that in 2019(43.04%)( χ 2=68 944.95, P <0.01). After adjustment for covariates, the odds ratio and 95% confidence interval for poor vision were 1.17(1.13-1.20), 1.07(1.04-1.10), 0.67 (0.65-0.69) and 0.62(0.60-0.64) in students with online class time, recreational screen time, indoor and outdoor activity time in the highest tertile, compared with the lowest tertile groups. Conclusion Increased rate of poor vision among primary and secondary schoool students deserves further concern. It is necessary to strengthen intervention of eyesight protection. Policies and programs aimed at improving opportunities for physical activities and decreasing multiple screen behaviors should be given priority.
