AIM: To investigate the comorbidity status of myopia and depressive symptoms among middle school students, identify key influencing factors, and establish a prediction model, thereby providing empirical evidence for the comprehensive intervention of these two conditions.METHODS: Students from 3 middle schools in Feidong county were recruited between 2022 and 2024. Myopia was defined as uncorrected visual acuity ≤5.0 with spherical equivalent refraction <-0.50 diopters(D). Depressive symptoms were assessed using the Center for Epidemiologic Studies Depression Scale(CES-D), with a score ≥16 indicating the presence of depressive symptoms. A database was established and data were entered using EpiData software. Pearson's Chi-square test and multivariate Logistic regression analysis were performed to identify influencing factors and screen variables with R statistical software(version 4.5.2). Finally, a Stacking ensemble prediction model was constructed using Python3.13 software. RESULTS: The study included 2 476 students, consisting of 1 380 males and 1 096 females. The overall detection rate of myopia-depressive symptom comorbidity among the studied students was 14.54%. Univariate analysis showed that variables were significantly associated with the comorbidity, including family structure, grade level, sugar-sweetened beverage intake, exercise frequency, school bullying, and parental physical or verbal abuse(all P<0.05). Multivariate Logistic regression analysis identified the following risk factors: higher grade levels(8th grade: OR=1.9143, 95%CI: 1.1096-3.3024; 9th grade: OR=1.7884, 95%CI: 1.0506-3.0444; 11th grade: OR=2.1847, 95%CI: 1.1980-3.9840; 12th grade: OR=3.4606, 95%CI: 1.8250-6.5621), daily consumption of sugar-sweetened beverages more than once(OR=3.1383, 95%CI: 1.7112-5.7560), low frequency of moderate-to-vigorous exercise on weekends and holidays(mostly achievable: OR=3.3115, 95%CI: 1.009-10.8685), alcohol consumption(OR=4.4021, 95%CI: 2.7383-7.0766), daily sedentary time exceeding 10 h(OR=1.8594, 95%CI: 1.2141-2.8476), lack of puberty education(OR=3.0098, 95%CI: 2.0659-4.3848), and exposure to parental physical or verbal abuse(OR=2.4050, 95%CI: 1.1484-5.0364). Protective factors included no experience of school bullying(OR=0.0055, 95%CI: 0.0002-0.1602), no history of severe injury(OR=0.3118, 95%CI: 0.1823-0.5332), outdoor activities during class breaks(OR=0.1672, 95%CI: 0.0752-0.3719), and moderate after-school homework duration(2-3 h per day: OR=0.4802, 95%CI: 0.2620-0.8801). The constructed Stacking prediction model demonstrated good discriminative ability, with an area under the receiver operating characteristic curve(AUC)of 0.855, a sensitivity of 81.5%, and a specificity of 74.0%. Key predictive factors included alcohol consumption status, location of recess activities, unhealthy lifestyle composite index(interaction term between sedentary duration and sugar-sweetened beverage intake frequency), academic stress index(interaction term between sedentary duration and homework duration), and after-school homework duration.CONCLUSION: The comorbidity of myopia and depression among middle school students is jointly influenced by multiple factors such as lifestyle, academic pressure, and family/campus environment. It is advocated to implement a three-level intervention system that includes restricting the sale of sugar-sweetened beverages, conducting psychological screening for sedentary students, and carrying out family-school-medical collaborative management of drinking behaviors. This model can be applied to school health screening and the early identification of high-risk groups in community adolescent health management. It is suitable for middle school students in regions with similar economic levels, but not applicable to students receiving special education or those with severe organic diseases.

BACKGROUND/OBJECTIVES: Edible insects are increasingly being recognized as sustainable protein sources with potential lipid-lowering properties. In this study, we investigated the effects of protein hydrolysates from 3 edible insects, Tenebrio molitor (TM), Protaetia brevitarsis (PB), and Gryllus bimaculatus (GB), on lipid metabolism in 3T3-L1 adipocytes.MATERIALS/METHODS: Treat cells with different concentrations of insect hydrolysates for 48 h during adipocyte differentiation. To evaluate the lipid-lowering effects of insect hydrolysates, analyses were conducted using Oil Red O staining, western blotting and quantitative real-time polymerase chain reaction. RESULTS: Non-toxic concentrations (0.25, 0.5, and 1 mg/mL) of the hydrolysates were applied during adipocyte differentiation for 48 h. All 3 hydrolysates significantly reduced intracellular lipid accumulation, with the PB hydrolysate demonstrating superior effects. PB uniquely stimulated lipolysis, as indicated by increased free fatty acid and glycerol release, accompanied by enhanced phosphorylation of hormone-sensitive lipase. Additionally, the PB hydrolysate upregulated key genes involved in adipocyte metabolism, including Pparg, Cebpa, aP2, and ApN. CONCLUSION PB hydrolysate exhibits distinct metabolic benefits, highlighting its potential as a functional food ingredient for obesity management. Further in vivo studies are required to explore the underlying mechanisms and therapeutic applications.

Objective To investigate the clinicopathological features of odontogenic myxoma(OM).Methods The clinicopath-ologic data of 15 patients with odontogenic myxoma(OM)diagnosed by routine pathology in Stomatological Hospital Affiliated to Nanjing Medical University from January 2013 to June 2023 were retrospectively analyzed.Results(1)The most common cases were female(66.7％),20-40 years old(73.3％),mandible(60.0％)and posterior dental area(93.3％).(2)The characteristic imaging findings were multilocular cystic low-density radiography,resembling honey comb/tennis racket/soap bubble structures.(3)Microscopi-cally,star or spindle tumor cells can be seen scattered in the background of light blue mucoid matrix,and occasionally a few odonto-genic epithelial clusters.(4)In 15 odontogenic myxoma(OM)samples,①β-catenin was not expressed in 1 case of mucous type,par-tially or diffusely expressed in 6 cases,not expressed in 2 cases of fibrous type,partially or diffusely expressed in 6 cases;②CD34 and S100 were negative;③Ki-67 index was lower than 1％.(5)Of the 15 patients,only one relapsed,and the rest had a good prognosis.(6)Surgical treatment is the main treatment plan at present,and the appropriate surgical plan should be selected according to the size of the tumor,the scope of the lesion and the situation of the patient.Conclusion Although odontogenic myxoma is a benign tumor,it is locally invasive and recurrent.It is necessary to distinguish it from low-grade malignant myxosarcoma,chondromyxoid fibroma and odontogenic fibroma.Understanding of and familiarity with its clinicopathological features is helpful to its diagnosis and improving the prognosis of patients.

Objective:To establish a serum detection method of surface-enhanced Raman spectroscopy (SERS) combining with machine learning for early screening of colorectal cancer (CRC).Methods:Serum samples were collected from 150 CRC patients diagnosed at Jiangdu People′s Hospital, Affiliated to Yangzhou University, and also from 37 healthy subjects. Gold nanohexapod (AuNHs) arrays were prepared using an oil-water interface self-assembly method. A 5 μl serum sample was applied onto the AuNHs array. Scatheless and rapid detection for serum were performed using a Renishaw inVia Raman spectrometer at room temperature with a laser wavelength of 785 nm, exposure time of 10 s, and power of 5 mW. The raw SERS spectra were preprocessed using Savitzky-Golay smoothing, AsLS baseline correction, and Min-Max normalization with Origin 2019 software. Furthermore, the principal component analysis (PCA)-support vector machine (SVM) model was constructed using Python′s scikit-learn library. Leave-One-Out Cross-Validation (LOOCV) was used to evaluate the model′s accuracy, sensitivity, specificity, and area under the curve (AUC).Results:The AuNHs arrays exhibited uniform morphology. The relative standard deviation (RSD) of the SERS intensity at 1 080 cm -1 was 5.69%, and the RSD of the SERS intensity at 1 340 cm -1 was 6.20%. The limit of detection (LOD) of the AuNHs array was 9.42×10 -12 mol/L. The PCA-SVM model achieved an accuracy of 90.91% (170/187), sensitivity of 96.79% (181/187), specificity of 99.47% (186/187), and an AUC of 0.98. The most significant characteristic peaks distinguishing different CRC stages were at 747, 940, 1 000, 1 447, and 1 612 cm -1. Conclusion:The serum detection method based on SERS combined with machine learning can accurately screen CRC with higher accuracy, sensitivity, and specificity, demonstrating potential clinical application value.
