Executive function(EF) is an advanced cognitive function of the central nervous system, and is closely related to an individual's capacity for daily living and adaptation. Patients with attention deficit hyperactivity disorder (ADHD) typically exhibit significant executive dysfunction. While most existing studies on the executive function of individuals with ADHD are cross-sectional, and little is known about the longitudinal maturation process of related brain structures and functional connectivity patterns. The findings indicate that ADHD patients exhibit differential developmental trajectories in brain structural and functional connectivity compared with typically developing group.Furthermore, there is a lifespan association between abnormal brain network development and ADHD symptoms. This article aims to elucidate the characteristics of executive function deficits in ADHD patients across different developmental stages, examining their relationship with the nervous system’s development from a development perspective.

Objective:To assess the association between temperature and risk of animal injury, and identifying vulnerable populations.Methods:Based on a time-stratified case-crossover design, the number of animal injuries monitored in hospitals of Guangdong Provincial Injury Surveillance System in 2011 and 2015-2016 was included, and the daily meteorological data were derived from the fifth generation of European ReAnalysis-Land, which was produced by the European Centre for Medium-Range Weather Forecasts. Conditional logistic regression combined with a distributed lagged nonlinear model was applied to analyze the association of temperature and animal-specific injuries. We also conducted stratified analysis by region, sex, age, occupation, and location of injury occurrence.Results:There was an almost linear relationship between temperature and the occurrence of animal injury. The excess risk ( ER) of animal injury was 2.65% (95% CI: 2.27%-3.04%) for a 1 ℃ rise in temperature with much higher risk of occurrence ( ER=9.34%, 95% CI: 7.57%-11.13%) for non-mammalian injury than that for mammalian injuries ( ER=2.30%, 95% CI: 1.90%-2.70%). Stratified analysis revealed that the occurrence of animal injury was more susceptible to temperature influences in urban ( ER=2.78%, 95% CI: 2.35%-3.21%), female ( ER=2.71%, 95% CI: 2.16%-3.27%), the elderly aged 60 years and above ( ER=3.05%, 95% CI: 1.65%- 4.47%), farmer ( ER=4.66%, 95% CI: 3.03%-6.32%) and agricultural area ( ER=10.63%, 95% CI: 7.57%-13.79%) than their correspondents. In terms of mammalian injury, dog bites showed the highest risk ( ER=2.71%, 95% CI: 2.12%-3.30%). In terms of non-mammalian,snake injuries were highly influenced by temperature ( ER=16.74%, 95% CI: 11.33%-22.40%). Conclusions:The ambient temperature rises could increase the risk of animal injury with much higher risk for non-mammalian than that for mammalian injuries. Our findings suggest that global warming may increase the risk and disease burden from animal injuries.

The liver performs multiple life-sustaining functions. Hepatic diseases, including hepatitis, cirrhosis, and hepatoma, pose significant health and economic burdens globally. Along with the advances in nanotechnology, mesoporous silica nanoparticles (MSNs) exhibiting diversiform size and shape, distinct morphological properties, and favorable physico-chemical features have become an ideal choice for drug delivery systems and inspire alternative thinking for the management of hepatic diseases. Initially, we introduce the physiological structure of the liver and highlight its intrinsic cell types and correlative functions. Next, we detail the synthesis methods and physicochemical properties of MSNs and their capacity for controlled drug loading and release. Particularly, we discuss the interactions between liver and MSNs with respect to the passive targeting mechanisms of MSNs within the liver by adjusting their particle size, pore diameter, surface charge, hydrophobicity/hydrophilicity, and surface functionalization. Subsequently, we emphasize the role of MSNs in regulating liver pathophysiology, exploring their value in addressing liver pathological states, such as tumors and inflammation, combined with multi-functional designs and intelligent modes to enhance drug targeting and minimize side effects. Lastly, we put forward the problems, challenges, opportunities, as well as clinical translational issues faced by MSNs in the management of liver diseases.

Objective:To explore the effect of contezolid on platelet count in patients with severe pneumonia and analyze the risk factors.Methods:The study was designed as a retrospective case-control study. The research subjects were selected from patients with severe pneumonia who were admitted to the Department of Respiratory and Critical Care Medicine of Shaanxi Provincial People′s Hospital from July 1, 2022 to November 30, 2024 and were treated with contezolid or linezolid. The clinical data of patients were collected and the incidence of thrombocytopenia [platelet count (PLT)<100×10 9/L after medication], the PLT before and at 1 week of treatments, and the lowest PLT value during treatments were compared in patients treated with contezolid and linezolid. The patients were divided into 2 groups based on whether contezolid- related thrombocytopenia occurred. The clinical characteristics of the patients were compared, and the independent risk factors of contezolid-related thrombocytopenia were analyzed by binary logistic regression method. Results:A total of 175 patients were included, among whom 73 received contezolid and 102 received linezolid. There was no statistically significant difference in PLT between the 2 groups before medication ( P=0.364). Compared with patients treated with linezolid, the incidence of thrombocytopenia in patients treated with contezolid was lower [19.2% (14/73) vs. 40.2% (41/102)], and the PLT at 1 week of treatments and the lowest value of PLT during treatments were higher. The differences were all statistically significant (all P<0.05). Compared with patients without contezolid-related thrombocytopenia(59 patients), patients who developed thrombocytopenia after using contezolid had a longer duration of contezolid medication, lower PLT and creatinine clearance rate before medication, and higher procalcitonin and serum creatinine levels before medication. All these differences were statistically significant (all P<0.05). The results of binary logistic regression analysis showed that lower PLT [odds ratio ( OR)=0.971, 95% confidence interval ( CI): 0.950-0.992, P=0.008] and higher procalcitonin level ( OR=7.292, 95% CI: 1.067-49.814, P=0.043) before medication and longer duration of contezolid medication ( OR=1.165, 95% CI: 1.002-1.355, P=0.046) were the independent risk factors of contezolid-related thrombocytopenia. Conclusions:Compared with linezolid, contezolid has a relatively safer profile in the treatment of patients with severe pneumonia and the risk of thrombocytopenia after medication is lower. Patients with lower PLT and higher procalcitonin levels before medication, and those with a longer duration of contezolid medication have a higher risk of contezolid-related thrombocytopenia and should be closely monitored.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

COVID-19 associated fundus lesions are mostly vascular occlusion or inflammatory changes. The affected vessels include both retinal macrovessels and microvessels, and the inflammatory changes are mainly autoimmune lesions. Clinically, the different lesions present as various fundus diseases, with varying degrees of impact on visual function. The mechanism of these lesions is considered to be related to direct injury of SARS-CoV-2, abnormal coagulation or inflammatory response caused by SARS-CoV-2. Awareness of fundus lesions associated to COVID-19 is helpful to figure out the pathophysiological mechanism of COVID-19 and promote in-depth studies for a deeper and complete understanding of the occurrence and full impact of COVID-19, emphasizing the importance of early prevention and control of the disease, and highlighting the significance of early intervention of the fundus diseases caused by COVID-19.
