Objective:
To summarize strategies for improving childhood hypertension, so as to provide evidencebased recommendations for poliymaking and practice childhood hypertension management in China.
Methods:
From March to April 2024, child health stakeholders from five districts in Hangzhou were selected using a combination of stratified and convenience sampling methods. Data were analyzed using a groundedtheory approach. During the indepth interview phase, six policymakers were interviewed. Focus group discussions were conducted with school administrators, healthcare providers, and parents, comprising a total of 62 participants.
Results:
Through threelevel coding, 116 initial categories were identified(e.g., "trend of younger age" "difficulty in behavior change"), 35 main categories (e.g., "higher incidence compared to the past" "caused by comprehensive influencing factors"), and 12 core categories (e.g., "epidemic status" "influencing factors"). Finally, the cognitive status, problem analysis, and management strategies of children hypertension were constructed.
Conclusion
Effective prevention and control of childhood hypertension requires coordinated efforts among governments, schools, families, and society to establish a comprehensive management system, with dynamic monitoring and evaluation to optimize policy implementation.

Diabetic retinopathy(DR)is one of the most common and severe microvascular complications in diabetic patients and has become one of the leading causes of blindness worldwide. With the continuous rise in the prevalence of diabetes, in-depth exploration of the pathogenesis of DR and effective intervention measures is of great clinical significance. The mechanistic target of rapamycin(mTOR), as a protein kinase, is widely involved in cellular processes such as growth, metabolism, and autophagy. Research indicates that the mTOR signaling pathway plays a crucial regulatory role in the pathological progression of DR, and its abnormal activity can disrupt retinal cell autophagy function, thereby accelerating cellular damage and disease progression. Autophagy, as an important regulatory mechanism for cellular homeostasis, maintains cellular functional balance by clearing damaged organelles and protein aggregates. This article provides a systematic review of the structural and functional aspects of the mTOR signaling pathway, the molecular regulatory mechanisms of autophagy, and their roles in retinal pathological changes. By summarizing current research findings, the article aims to clarify the key regulatory role of the mTOR-autophagy axis in DR, providing theoretical support for elucidating the molecular pathogenesis of DR and offering potential targets and research directions for developing novel targeted therapeutic strategies, thereby holding significant scientific and clinical value.

Diabetic retinopathy(DR)is one of the common causes of visual impairment and blindness in adults, which is caused by various pathogenesis. Although the mechanism of DR has not been elucidated yet, the destruction of blood-retinal barrier is a key process. As a highly endothelial-specific factor in promoting the growth of vascular endothelial cell, vascular endothelial growth factor(VEGF)plays a crucial role in the formation of pathological retinal neovascularization and the destruction of blood-retinal barrier. Therefore, a comprehensive understanding of the etiology and pathogenesis of blood-retinal barrier damage promoted by VEGF is critical for exploring the pathogenesis of DR. In this study, the underlying relationship between VEGF and the mechanism of blood-retinal barrier damage, including retinal vascular endothelial cell permeability, vascular inflammatory response, apoptosis, oxidative stress, mitochondrial damage and endoplasmic reticulum stress, with a view to providing a reference for the study in VEGF in the pathogenesis of blood-retinal barrier damage in DR.

Objective:To analyze the depressive symptoms of physical and mental workers and the impact of their behavior and lifestyle on their depressive symptoms.Methods:In August 2022, a cross-sectional study design was adopted to select 553 workers as research subjects using cluster sampling. General demographic information, health-related behaviors and lifestyles were collected, and their depressive symptoms were evaluated using the Chinese version of the Patient Health Questionnaire 9 (PHQ-9). The differences in general demographic information, health-related behaviors and lifestyles between physical and mental workers were analyzed, and logistic regression was used to analyze the influencing factors of depressive symptoms in occupational populations.Results:Among the 553 subjects, 317 were physical workers (57.32%) and 236 were mental workers (42.68%). Statistically significant differences were observed between the two groups in terms of education level, monthly income, smoking rate, regular physical exercise rate and appropriate sleep time rate ( P<0.05). The score and the detection rate of depression symptoms among physical workers were (9.67±2.75) points and 20.82% (66/317), respectively, which were higher than those of mental workers [(8.34±2.18) points, 12.71% (30/236) ] ( t=6.13, χ 2=6.20, P<0.05). The results of logistic regression analysis showed that smoking, regular physical exercise, appropriate sleep time and mental work were influencing factors of depressive symptoms among the occupational population ( OR=1.592, 95% CI: 1.316-1.825; OR=0.659, 95% CI: 0.416-0.830; OR=0.502, 95% CI: 0.257-0.717; OR=0.839, 95% CI: 0.522-0.967; P<0.05) . Conclusion:The depressive symptoms of physical workers are more serious than those of mental workers. Low education level, not frequently participating in physical exercise, smoking and sleep disorder are potential risk factors that affect the depressive symptoms of the occupational population.

Due to the increasingly severe situation of pathogen resistance, the efficacy of classical antibiotics has declined, and the difficulty of treating community-acquired pneumonia (CAP) has gradually increased. Omadacycline was approved for marketing in China in December 2021 and has been approved for treating community-acquired bacterial pneumonia and acute bacterial skin and skin structure infection in adults. Based on introducing the pathogen resistance of CAP, this article systematically reviews the antibacterial activity and resistance, pharmacokinetic characteristics, and clinical efficacy of omadacycline. It is found that its antibacterial spectrum is wide, its bioavailability is high, and its safety is good. Its pharmacokinetic parameters are not affected by the patients’ age, gender, liver and kidney function, or drug interactions, and it is effective against multiple drug-resistant bacteria, Gram-negative bacteria producing extended-spectrum β-lactases, atypical pathogens, etc. It can be used as one of the treatment options for CAP. However, due to limited clinical research data and the short clinical application time of the drug, more clinical studies are still needed to verify its efficacy as a monotherapy or in combination with other antibiotics for severe pneumonia patients.
