ObjectiveTo investigate the level of hepatitis B surface antibody (anti-HBs) among preschool children (aged 3‒6 years) and primary and secondary school students in Tonglu County, Zhejiang Province, to evaluate the effectiveness of hepatitis B vaccination, and to provide a basis for hepatitis B prevention and control in the region. MethodsAs part of the 2023 Tonglu County Urban and Rural Residents Health Examination Program, blood samples were collected during health check-ups. Fingertip blood samples were obtained from preschool children, while venous blood samples were collected from primary and secondary school children. The anti-HBs levels in blood (positive + / negative -) were qualitatively tested using hepatitis B surface antibody test kits (latex method). The differences in anti-HBs positivity rates among different age groups were analyzed. ResultsBetween April 1, 2023 and June 30, 2023, a total of 52 919 individuals were surveyed, including 11 973 preschool children and 40 946 primary and secondary school students. The overall anti-HBs positivity rate was 39.74%, with the highest positivity rate observed among preschool children (60.20%). Age was negatively correlated with the anti-HBs positivity rate (P<0.001). No significant gender differences in anti-HBs positivity rates were observed. The anti-HBs positive rate in rural areas was higher than that in urban areas, with statistically significant differences across school grade groups (primary grades 1‒3, grades 4‒6, middle school, and high school) (P<0.001). ConclusionThe anti-HBs positivity rate among preschool and school-age children in Tonglu County decreases with age and remains relatively low. It is recommended to strengthen the monitoring of hepatitis B antibody levels and promote health education among preschool and school-age children. Children who have not completed the full hepatitis B vaccination should receive timely catch-up vaccination.

Objective To investigate the impact of various health education intervention strategies on the proper use of personal respiratory protective equipment (RPE) among workers exposed to dust. Methods Dust-exposed workers were recruited from 60 selected enterprises in Guangdong Province using cluster random sampling method. They were randomly allocated to the control, low-intensity intervention, and high-intensity intervention groups, with 358, 346, and 371 workers in each group, respectively. Workers in the control group received no designed intervention. Workers in the low-intensity intervention group received traditional plus mobile health education on the proper use of RPE. Workers in the high-intensity intervention group received all components of the low-intensity intervention, supplemented with peer education. The intervention lasted for six months. RPE usage was compared among the three groups of workers before and after the intervention. Results Workers in the control, low-intensity intervention, and high-intensity intervention groups showed higher rates of both RPE wearing and correct RPE wearing after the intervention than before it within their respective groups (RPE wearing rate: 94.1% vs 99.2%, 95.7% vs 100.0%, 94.6% vs 100.0%, all P<0.01; correct RPE wearing rate: 66.8% vs 91.1%, 67.3% vs 95.7%, 66.6% vs 96.5%, all P<0.01). Post-intervention correct RPE wearing rates were highest in the high-intensity intervention group, followed by the low-intensity intervention group, and the control group, with the percentage of 96.50%, 95.66% and 91.06%, respectively (P<0.01). Binary logistic regression analysis result showed that different intervention strategies affected the correct use of personal RPE among dust-exposed workers after adjusting for gender, age, and other confounding factors (P<0.05). Compared with the control group, the rates of correct RPE use increased in the low-intensity intervention group and the high-intensity intervention group (odd ratio was 2.14 and 3.01; 95% confidence interval was 1.12 - 4.10 and 1.53 - 5.91, respectively). Conclusion The implementation of traditional plus mobile health education interventions on the proper use of RPE can promote correct RPE utilization among dust-exposed workers, and integrating peer education further enhances the intervention effectiveness.

ObjectiveTo investigate the effects of Jiaohong pills (JHP) and its prescription, Pericarpium Zanthoxyli (PZ) and Rehmanniae Radix (RR) cognitive dysfunction in scopolamine-induced Alzheimer's disease (AD) mice and its mechanism through pharmacodynamic and metabolomics study. MethodThe animal model of AD induced by scopolamine was established and treated with PZ, RG and JHP, respectively. The effects of JHP and its formulations were investigated by open field test, water maze test, object recognition test, avoidance test, cholinergic system and oxidative stress related biochemical test. Untargeted metabolomics analysis of cerebral cortex was performed by ultra-performance liquid chromatography-Quadrupole/Orbitrap high resolution mass spectrometry (UPLC Q-Exactive Orbitrap MS). ResultThe behavioral data showed that, compared with the model group, the discrimination indexes of the high dose of JHP, PZ and RR groups was significantly increased (P<0.05). The staging rate of Morris water maze test in the PZ, RR, high and low dose groups of JHP was significantly increased (P<0.05, P<0.01), the crossing numbers in the PZ, JHP high and low dose groups were significantly increased (P<0.05, P<0.01); the number of errors in the avoidance test were significantly reduced in the PZ and high-dose JHP groups (P<0.01), and the error latencies were significantly increased in the JHP and its prescription drug groups (P<0.01). Compared with the model group, the activities of acetylcholinesterase in the cerebral cortex of the two doses of JHP group and the PZ group were significantly increased (P<0.05, P<0.01), and the activity of acetylcholinesterase in the high-dose JHP group was significantly decreased (P<0.05), and the level of acetylcholine was significantly increased (P<0.01). At the same time, the contents of malondialdehyde in the serum of the two dose groups of JHP decreased significantly (P<0.05, P<0.01). The results of metabolomics study of cerebral cortex showed that 149 differential metabolites were identified between the JHP group and the model group, which were involved in neurotransmitter metabolism, energy metabolism, oxidative stress and amino acid metabolism. ConclusionJHP and its prescription can antagonize scopolamine-induced cognitive dysfunction, regulate cholinergic system, and reduce oxidative stress damage. The mechanism of its therapeutic effect on AD is related to the regulation of neurotransmitter, energy, amino acid metabolism, and improvement of oxidative stress.

ObjectiveTo preliminarily confirm the effective anti-lung cancer sites of Momordicae Semen and Epimedii Folium and study their mechanism of action. MethodOn the basis of preliminary research, the extraction method of Momordicae Semen and Epimedii Folium was optimized and the effective parts were screened under the guidance of pharmacological effects. Different ethanol elution and water elution sites of Momordicae Semen and Epimedii Folium were obtained through adsorption and elution with D101 macroporous resin. The methylthiazolyldiphenyl-tetrazolium bromide (MTT) colorimetric assay was used to detect the effects of total drug extracts and different elution sites on the proliferation of various tumor cell lines, and to screen for the optimal elution site and tumor sensitive strains. Flow cytometry was used to detect the effect of the elution sites of Momordicae Semen and Epimedii Folium on intracellular reactive oxygen species (ROS) and apoptosis in A549 cells. Western blot was used to compare the expressions of tumor protein 53 (p53), Bcl-2-associated X protein (Bax), cysteinyl aspartate specific proteinase-3 and 9 (Caspase-3 and Caspase-9) proteins in A549 cells. ResultThe inhibitory effect of Momordicae Semen on the proliferation of A549 cells was better than the kernel of Momordicae Semen, with 50% inhibitory concentration (IC50) being (86.83±2.88) mg·L-1 and (95.10±18.13) mg·L-1, respectively. The effect of total extracts of Epimedii Folium on A549 anti proliferation IC50 value was (4.71±0.81) mg·L-1. The IC50 values of the 40%, 60%, and 80% ethanol and anhydrous ethanol eluted macroporous resins of the total extracts of Momordicae Semen and Epimedii Folium inhibiting A549 proliferation were (45.32±4.38)、 (14.95±0.73)、 (17.07±1.76)、 (14.46±2.35)、 (51.7±2.26)、 (12.37±0.67)、 (20.29±0.93)、 and (3.43±0.91) mg·L-1, respectively. Compared with the normal group, the 1∶1 combination of Momordicae Semen and Epimedii Folium inhibited A549 cell proliferation in a time-dependent and concentration-dependent manner. Compared with the normal group, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased intracellular ROS expression (P<0.01). Compared with the normal group, 12.5, 25, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of A549 cell apoptosis (P<0.01). Compared with the normal group, 25, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of p53 in A549 cells (P<0.01). Compared with the normal group, 12.5, 25, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly increased the expression of Bax (P<0.01). Compared with the normal group, 50 mg·L-1 of the combination of Momordicae Semen and Epimedii Folium significantly reduced the expressions of Caspase-3 and Caspase-9 (P<0.01). ConclusionThe anti-tumor effect of Momordicae Semen is better than that of the kernel of Momordicae Semen. The anti-tumor substances of Momordicae Semen and Epimedii Folium mainly concentrate in the 60% ethanol to anhydrous ethanol elution site. A549 cells are sensitive to the 1∶1 combination of Momordicae Semen and Epimedii Folium, which can effectively inhibit the cell proliferation. The mechanism may be related to increasing the generation of ROS in A549 cells, promoting their apoptosis, increasing the expressions of apoptotic proteins such as p53 and Bax, and reducing the expressions of Caspase-3 and Caspase-9.

Diabetic retinopathy is one of the microvascular complications of diabetes and a major cause of blindness in adults. Early screening is an effective way to reduce blindness caused by diabetic retinopathy. The diabetic retinopathy is one of the chronic retinal diseases highlighted in the "14th Five-Year" National Eye Health Plan (2021-2025). The establishment of effective and practical community screening model is a powerful guarantee to complete early screening. It is of great significance to standardize screening methods, screening personnel duties, equipment allocation, referral conditions and screening sustainability. Chinese fundus disease and related field experts developed the consensus through a serious, comprehensive, and complete discussion, to provide more reference for establishing a suitable community screening model of diabetic retinopathy and increasing the screening rate of diabetic retinopathy.

Tumor metastasis is the major cause of death for tumor patients and the key bottleneck of clinical treatment. In recent years, basic and clinical studies have recognized that tumor microenvironment (TME) is highly correlated with tumor metastasis, which provides hope for anti-metastatic drug development and clinical treatment. At present, the mainstream studies on TME represented by immune checkpoint inhibitors (ICIs) mainly focus on the rectification of immune function of T cells and B cells. However, a large number of studies have shown that the significance of other members of TME for tumor metastasis cannot be ignored, which greatly reflects the progress of anti-metastatic research based on TME regulation. This review focused on tumor metastasis, summarized the mechanism of action of non-T and non-B immune cells [tumor-associated macrophages (TAMs) and tumor-associated neutrophils (TANs)] and non-immune members [vascular endothelial cells (ECs), tumor-associated fibroblasts (CAFs), and blood platelet] in the process of tumor metastasis in TME based on the literature over the recent five years, and explored their key value in the treatment of metastasis. At the treatment level, this review focused on the perspective of the integration of frontier and traditional methods and took the functional homeostasis remodeling of TME as the entry point to summarize the activity and mechanism of traditional Chinese medicine (TCM) regulation of non-T and non-B immune cells and non-immune members and highlight its advantages and characteristics in clinical intervention of metastasis. This review helps to break through the limitations of over-reliance on T and B immune cells in anti-metastatic research, make the research rely on a wider range of cell groups, explore the potential value of TME in anti-metastatic drug intervention, and enrich the idea and strategy of understanding the anti-metastatic pharmacological activity. The review is also expected to provide a broader vision for the research and development of new anti-metastatic drugs.

Demyelination of the central nervous system often occurs in neurodegenerative diseases, such as multiple sclerosis (MS). The myelin sheath, a layer of myelin membrane wrapping the axon, plays a role in the rapid conduction and metabolic coupling of impulses for neurons. The exposure of the axon will lead to axonal degeneratio, and further neuronal degeneration, which is the main cause of dysfunction and even disability in patients with demyelinating neurodegenerative diseases. In addition to the demyelination of mature myelin sheath, remyelination disorder is also one of the major reasons leading to the development of the diseases. The myelin sheath is composed of oligodendrocytes (OLs) derived from oligodendrocyte progenitor cells (OPCs) which are differentiated from neural stem cells (NSCs). The process of myelin regeneration, i.e., remyelination, is the differentiation of NSCs into OLs. Recent studies have shown that this process is regulated by a variety of genes. MicroRNAs, as important regulators of neurodegenerative diseases, form a complex regulatory network in the process of myelin regeneration. This review summarizes the main molecular pathways of myelin regeneration and microRNAs involved in this process and classifies the mechanisms and targets. This review is expected to provide a theoretical reference for the future research on the treatment of demyelinating diseases by targeting the regulation of microRNAs.
