AIM: To screen and analyze the influencing factors of myopia among primary and secondary school students and establish a predictive model to provide ideas for the prevention and control measures of myopia among children and adolescents.METHODS:A total of 1 759 primary and secondary school students from 2 primary schools, 2 junior high schools, 2 senior high schools and 1 vocational high school in the urban area of Qingdao were sampled by means of stratified cluster sampling in September 2023. Vision screening and a questionnaire survey on influencing factors were carried out based on machine learning algorithms. The screening and determination were mainly conducted in accordance with the Standard Logarithmic Visual Acuity Chart(GB/T11533-2011)and the Specifications for Screening Myopia in Children and Adolescents. The influencing factors of myopia were analyzed and a prediction model was developed based on the machine learning algorithms LASSO in combination with XGBoost, and visualization was achieved through an interactive Nomogram. Statistical analysis was performed using R statistical software version 4.3.3.RESULTS:The screening prevalence of myopia among primary and secondary school students in the urban area of Qingdao was 70.61%(1 242 cases). The optimal predictive variables for screening were grade, gender, whether parents were myopic, daily indoor sedentary time, appropriate distance between eyes and books during reading and writing, daily sleep time, distance between eyes and TV screen when watching TV/playing video games exceeding 3 meters, the playground during breaks, total duration of tutorial classes, how often eyes are rested during near work, daily computer usage time, and average daily homework time after school, totaling 12 influencing factors. The AUCs of the training set and test set were 0.770(95%CI:0.751-0.789)and 0.732(95%CI:0.714-0.750), respectively.CONCLUSION: A machine learning-based prediction model was developed and validated to predict the risk of myopia onset in primary and secondary school students, accompanied by effective visualization techniques.

Methods: Motor-evoked potentials (MEPs) and somatosensory-evoked potentials (SEPs) were recorded in 48 patients with TOLF (hybrid 20 vs. en bloc 28) during surgery. Patients were categorized based on MEP/SEP improvement, deterioration, or no change, and MEP/SEP improvement rates were measured in the improvement group. Furthermore, all patients were assessed using the Ashworth and modified Japanese Orthopedic Association scores. Results: The incidences of both MEP/SEP improvement (21.4% vs. 25.0%, p=0.772) and deterioration (21.4% vs. 20.0%, p=0.904) were similar between the en bloc and hybrid laminectomy groups, and no difference in preoperative and postoperative clinical assessments was observed between the two groups (p>0.05). In four patients (4/28, 14.3%) undergoing en bloc laminectomy, MEP amplitudes initially increased after OLF removal but gradually decreased. This delayed MEP reduction did not occur in the hybrid laminectomy group. Furthermore, more patients undergoing en bloc laminectomy had CFL than those undergoing hybrid laminectomy (46.4% vs. 15.0%, p=0.023). In the improvement group, the hybrid laminectomy group exhibited higher MEP improvement rates in the bilateral abductor hallucis than the en bloc laminectomy group (left side: 213.4%±35.9% vs. 152.5%±41.0%, p=0.028; right side: 201.2%±32.0% vs. 145.2%±46.3%, p=0.043). Conclusions Compared with en bloc laminectomy, hybrid laminectomy may be a safe and effective method for treating multilevel TOLF, potentially reducing intraoperative spinal cord irritation and CFL and causing relatively better functional recovery.

BACKGROUND: Both medication and non-medication therapies are effective approaches to control blood pressure (BP) in hypertension patients. However, the association of joint changes in antihypertensive medication use and healthy lifestyle index (HLI) with BP control among hypertension patients is seldom reported, which needs to provide more evidence by prospective intervention studies. We examined the association of antihypertensive medication use and HLI with BP control among employees with hypertension in China based on a workplace-based multicomponent intervention program. METHODS: Between January 2013 and December 2014, a cluster randomized clinical trial of a workplace-based multicomponent intervention program was conducted in 60 workplaces across 20 urban areas in China. Workplaces were randomly divided into intervention (n = 40) and control (n = 20) groups. Basic information on employees at each workplace was collected by trained professionals, including sociodemographic characteristics, medical history, family history, lifestyle behaviors, medication status and physical measurements. After baseline, the intervention group received a 2-year intervention to achieve BP control, which included: (1) a workplace wellness program for all employees; (2) a guidelines-oriented hypertension management protocol. HLI including nonsmoking, nondrinking, adequate physical activity, weight within reference range and balanced diet, were coded on a 5-point scale (range: 0-5, with higher score indicating a healthier lifestyle). Antihypertensive medication use was defined as taking drug within the last 2 weeks. Changes in HLI, antihypertensive medication use and BP control from baseline to 24 months were measured after the intervention. RESULTS: Overall, 4655 employees were included (age: 46.3 ± 7.6 years, men: 3547 (82.3%)). After 24 months of the intervention, there was a significant improvement in lifestyle [smoking (OR = 0.65, 95% CI: 0.43-0.99; P = 0.045), drinking (OR = 0.52, 95% CI: 0.40-0.68; P < 0.001), regular exercise (OR = 3.10, 95% CI: 2.53-3.78; P < 0.001), excessive intake of fatty food (OR = 0.17, 95% CI: 0.06-0.52; P = 0.002), restrictive use of salt (OR = 0.26, 95% CI: 0.12-0.56; P = 0.001)]. Compare to employees with a deteriorating lifestyle after the intervention, those with an improved lifestyle had a higher BP control. In the intervention group, compared with employees not using antihypertensive medication, those who consistent used (OR = 2.34; 95% CI: 1.16-4.72; P = 0.017) or changed from not using to using antihypertensive medication (OR = 2.24; 95% CI: 1.08-4.62; P = 0.030) had higher BP control. Compared with those having lower HLI, participants with a same (OR = 1.38; 95% CI: 0.99-1.93; P = 0.056) or high (OR = 1.79; 95% CI: 1.27~2.53; P < 0.001) HLI had higher BP control. Those who used antihypertensive medication and had a high HLI had the highest BP control (OR = 1.88; 95% CI: 1.32-2.67, P < 0.001). Subgroup analysis also showed the consistent effect as the above. CONCLUSION These findings suggest that adherence to antihypertensive medication treatment and healthy lifestyle were associated with a significant improvement in BP control among employees with hypertension.

[Objective]To investigate the prevalence rate of chronic non-communicable diseases(NCDs)and the association with quality of life in middle-aged and elderly patients with HIV/AIDS.[Methods]This cross-sectional study surveyed 432 patients with HIV/AIDS(aged≥45 years)in the Infectious Disease Center in Guangzhou Eighth People's Hospital of Guangzhou Medical University,and 366 participants were included in the analysis after quality control.A questionnaire and the EuroQol 5-Dimensional 3-level version(EQ-5D-3L)were used to investigate NCDs and quality of life and Tobit regression model was used to estimate the association between chronic diseases and quality of life.[Results]Among the 366 participants,29(7.9%)had cardiovascular disease,45(12.3%)had hypertension,122(33.3%)had hyperglycemia,151(41.3%)had hyperlipidemia,7(1.9%)had cancer,17(4.6%)had chronic kidney disease,38(10.4%)had chronic liver disease,21(5.7%)had musculoskeletal disorders,and 253(69.1%)suffered from at least one type of chronic diseases.The median(lower and upper quartiles)of EQ-5D utility index was 1.000(0.964～1.000).Multivariate Tobit regression results of the total population showed that cancer[ba=-0.08,95%CI(-0.15,-0.01),P=0.036],chronic kidney disease[ba=-0.07,95%CI(-0.12,-0.02),P=0.006],musculoskeletal disease[ba=-0.09,95%CI(-0.13,-0.05),P<0.001],and≥3 types of chronic diseases[ba=-0.05,95%CI(-0.08,-0.01),P=0.013]were negatively correlated with EQ-5D utility index.The stratified analysis results of different CD4+T cell levels showed that hypertension[ba=-0.07,95%CI(-0.12,-0.02),P=0.007],chronic kidney disease[ba=-0.10,95%CI(-0.18,-0.03),P=0.006],musculoskeletal disease[ba=-0.15,95%CI(-0.22,-0.07),P<0.001]and≥3 types of chronic diseases[ba=-0.09,95%CI(-0.09,-0.01),P<0.001]were negatively correlated with EQ-5D utility index in the group with CD4≤500(cells/μL),whereas cancer[ba=-0.11,95%CI(-0.20,-0.01),P=0.031]was negatively correlated with EQ-5D utility index in the group with CD4＞500(cells/μL).[Conclusions]The prevalence rate of chronic non-communicable diseases in middle-aged and elderly patients with HIV/AIDS is relatively high.The classification of NCDs such as cancer or chronic kidney disease or other chronic diseases and the numbers of NCDs categories are negatively correlated with quality of life.However,this association varies among patients with HIV/AIDS of different CD4+T cell levels.It is suggested that we should try to prevent and identify NCDs at an early stage,strengthen linkages and integration of health services for AIDS and chronic NCDs,and jointly manage and control AIDS with chronic diseases to improve the quality of life among people living with HIV/AIDS.

ObjectiveTo investigate the therapeutic effect of Dayuanyin on acute lung injury induced by H1N1 infection and decipher the potential mechanism. MethodThe constituents in Dayuanyin were analyzed by ultra-high performance liquid chromatography-quadrupole-exactive orbitrap mass spectrometry （UHPLC-Q-Exactive Orbitrap MS）. Forty-eight female BALB/c mice were randomized into normal， model， oseltamivir （19.5 mg·kg^-1）， and low-， medium-， and high-dose （2.73， 5.46， 10.92 g·kg^-1） Dayuanyin groups. The normal and model groups were administrated with deionized water by gavage， and the other groups were administrated with the corresponding drugs by gavage. On day 3 of drug administration， the normal group received nasal inhalation of normal saline， and the other groups were inoculated intranasally with A/RP/8/34 （H1N1） for the modeling of influenza virus infection. Mice were administrated with drugs continuously for 7 days and weighed daily. Sampling was performed 12 h after the last administration， and the lung tissue was weighed to calculate the lung index. Hematoxylin-eosin staining was performed to observe the pathological and morphological changes of the lung tissue and bronchi. The cytometric bead array （CBA） was used to measure the serum levels of interferon-gamma （IFN-γ）， C-X-C motif ligand 1 （CXCL1）， tumor necrosis factor-alpha （TNF-α）， chemokine ligand 2 （CCL2）， interleukin-12p70 （IL-12p70）， chemokine ligand 5 （CCL5）， interleukin-1β （IL-1β）， chemokine （C-X-C motif） ligand 10 （CXCL10）， granulocyte-macrophage colony-stimulating factor （GM-CSF）， interleukin-10 （IL-10）， interferon-beta （IFN-β）， interferon-alpha （IFN-α）， and interleukin-6 （IL-6）. According to the results of mass spectrometry and network pharmacology， we analyzed the mechanism of Dayuanyin in treating acute lung injury caused by H1N1. The protein levels of extracellular signal-regulated kinase 1/2 （ERK1/2）， p38 mitogen-activated protein kinase （p38 MAPK）， nuclear factor-kappa B （NF-κB）， and their phosphorylated forms were determined by Western blot. The mRNA levels of myeloid differentiation factor 88 （MyD88）， Toll-like receptor 3 （TLR3）， Toll-like receptor 7 （TLR7）， and Toll-like receptor 8 （TLR8） in the lung tissue were measured by Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）. ResultA total of 57 compounds， including paeoniflorin and baicalein， were detected in Dayuanyin. Compared with the normal group， the model group showed decreased body weight （P<0.01）， lung edema and hemorrhage， increased lung index （P<0.01）， and elevated levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. Compared with the model group， Dayuanyin attenuated alveolar wall thickening， capillary congestion， and immune cell infiltration， reduced the alterations in body weight and lung index （P<0.01）， and down-regulated the protein levels of IFN-γ， IL-12p70， CCL5， IL-1β， CXCL10， GM-CSF， IFN-β， and IL-6 （P<0.01）. A total of 57 key genes were predicted by network pharmacological analysis， of which the MAPK signaling pathway was the main target signaling pathway. Compared with the normal group， the model group showed up-regulation in the protein levels of phosphorylation （p）-ERK1/2， p-p38 MAPK， and p-NF-κB （P<0.01） and the mRNA levels of TLR7， TLR8， MyD88， and TLR3 （P<0.05， P<0.01）. Compared with the model group， Dayuanyin lowered the phosphorylation levels of ERK1/2， p38 MAPK， and NF-κB p65 in a dose-dependent manner （P<0.01） and down-regulated the mRNA levels of TLR3， TLR7， TLR8， and MyD88 （P<0.01）. ConclusionDayuanyin can prevent and control H1N1 infection-induced acute lung injury by inhibiting the TLR/MAPK/NF-κB signaling pathway.

Objective To utilize bioinformatic approaches to elucidate the correlation between secreted phosphoprotein 1(SPP1)and immune infiltration in various malignancies,elucidating the mechanism of gene function in cancer-immune cell interplay.Methods Cancer samples were derived from the Cancer Genome Atlas(TCGA)and Genotype-tissue Expression(GTEx)database,examining SPP1 expression difference between tumors and normal tissues using Gene Expression Profiling Interactive Analysis(GEPIA2),and its correlation with different immune cells in extracellular matrix via TIMER2 Database.SPP1's association with interacting molecules was scrutinized on the STRING website,followed by assessment of its distinct functional state across various cancers from Cancer Single-cell State Atlas Database(Cancer SEA).Results In 32 tumor types,SPP1 mRNA is significantly elevated in 23 types of cancers and correlates heavily with fibroblast,integrin family,and CD44.Furthermore,the SPP1 gene exhibits profound specificity in tumor functions such as vascular invasion,metastasis,DNA damage,and repair.Conclusion Specific expression of SPP1 in tumors signifies a significant correlation with tumor immune cells in the extracellular matrix,promoting tumor progression and invasion.This suggests that targeted monitoring of SPP1 could serve as a prospective cancer diagnostics/therapeutics biomarker.
