Objective: To explore the association of physical activity and sugar sweetened beverage consumption with psychological sub health among middle school students in Bao an District, Shenzhen, so as to provide a reference for adolescent mental health promotion. Methods: A questionnaire survey was conducted in November 2024 by a stratified cluster random sampling method to select 6 926 junior and senior middle school students from 5 middle schools in Shenzhen. The questionnaire from Youth Risk Behavior Surveillance System was used to assess the consumption of sugar sweetened beverages, and physical activity Rating Scale was used to assess the level of physical activity, and Brief Instrument on Psychological Health of Youths was used to evaluate the psychological sub health status. The Chi -square test was used to analyze the differences in the detection rates of psychological sub health among different groups of middle school students, and a multivariate Logistic regression model was established to analyze the effects of physical activity and sugar sweetened beverage consumption and their combined effects on the psychological sub health of middle school students. Results: The detection rate of psychological sub health among middle school students in Bao an District, Shenzhen was 18.93%. Multivariate Logistic regression analysis showed that, after controlling for confounding factors such as gender, school stage, family residence, family economic status, parental literacy, academic stress and number of friends, lack of physical activity or excessive sugar sweetened beverage consumption were associated with increased risks of psychological sub health among middle school students ( OR =1.36, 1.45); and the highest risk of psychological sub health was found in middle school students who were lack of physical activity and excessive sugar sweetened beverage consumption ( OR =2.59) ( P <0.01). Further analysis by school stages showed that junior high school students with sufficient physical activity and excessive intake of sugary drinks ( ROR =2.10), lack of physical activity and excessive intake of sugary drinks ( ROR =2.31) were at higher risks of psychological sub health than senior high school students( P <0.05). Conclusions Insufficient physical activity and excessive sugar sweetened beverage consumption are closely associated with an increased risk of psychological sub health among middle school students. Effective interventions should be targeted to reduce the risk of psychological sub health problems among middle school students.

Objective: To explore the mechanism by which icariin alleviates viral myocarditis. Methods: CVB3-induced cardiomyocytes were used as an in vitro model of viral myocarditis to assess the effects of icariin treatment on cell viability, inflammation, and apoptosis. Moreover, the effects of icariin on ferroptosis and TLR4 signaling were assessed. After AC16 cells were transfected with TLR4 overexpression plasmids, the role of TLR4 in mediating the regulatory effect of icariin in viral myocarditis was investigated. Results: Icariin significantly elevated cell viability and reduced inflammatory factors TNF-α, IL-1β, IL-6, and IL-18. Flow cytometry revealed that icariin decreased apoptosis rate, and the protein expression of Bax and cleaved caspase 3 and 9 in CVB3-induced cardiomyocytes. Additionally, it suppressed ferroptosis including lipid peroxidation and ferrous ion, as well as the TLR4 signaling. However, TLR4 overexpression abrogated the modulatory effects of icariin. Conclusions: Icariin mitigates CVB3-induced myocardial injury by inhibiting TLR4-mediated ferroptosis. Further animal study is needed to verify its efficacy.

Objective To investigate the incidence rate,clinical characteristics,and prognosis of neonatal stroke in Shenzhen,China.Methods Led by Shenzhen Children's Hospital,the Shenzhen Neonatal Data Collaboration Network organized 21 institutions to collect 36 cases of neonatal stroke from January 2020 to December 2022.The incidence,clinical characteristics,treatment,and prognosis of neonatal stroke in Shenzhen were analyzed.Results The incidence rate of neonatal stroke in 21 hospitals from 2020 to 2022 was 1/15 137,1/6 060,and 1/7 704,respectively.Ischemic stroke accounted for 75％(27/36);boys accounted for 64％(23/36).Among the 36 neonates,31(86％)had disease onset within 3 days after birth,and 19(53％)had convulsion as the initial presentation.Cerebral MRI showed that 22 neonates(61％)had left cerebral infarction and 13(36％)had basal ganglia infarction.Magnetic resonance angiography was performed for 12 neonates,among whom 9(75％)had involvement of the middle cerebral artery.Electroencephalography was performed for 29 neonates,with sharp waves in 21 neonates(72％)and seizures in 10 neonates(34％).Symptomatic/supportive treatment varied across different hospitals.Neonatal Behavioral Neurological Assessment was performed for 12 neonates(33％,12/36),with a mean score of(32±4)points.The prognosis of 27 neonates was followed up to around 12 months of age,with 44％(12/27)of the neonates having a good prognosis.Conclusions Ischemic stroke is the main type of neonatal stroke,often with convulsions as the initial presentation,involvement of the middle cerebral artery,sharp waves on electroencephalography,and a relatively low neurodevelopment score.Symptomatic/supportive treatment is the main treatment method,and some neonates tend to have a poor prognosis.

Objective To analyze the accuracy of the new generation intraocular lens(IOL)formula and the Wang-Koch(WK)adjustment in individuals with severe myopia undergoing combined anterior-posterior surgery.Methods A total of 100 patients(100 eyes)with axial length(AL)＞26 mm undergoing combined anterior and posterior segment surgery in our department from June 2015 to June 2021 were enrolled in this study.Totally 13 IOL calculation formulas,such as Barrett Universal Ⅱ(BU Ⅱ),Emmetropia Verifying Optical(EVO),Kane,Haigis,Hoffer Q,Holladay,and SRK/T as well as the first generation linear WK eye axis optimization formula(Haigis-WK1,SRK/T-WK1,Hoffer Q-WK1,Holladay 1-WK1)and the second generation linear WK eye axis optimization formula(SRK/T-WK2,Holladay 1-WK2),were utilized to determine IOL diopter.The mean prediction error(ME),mean absolute error(MAE),median absolute error(MedAE),and percentage of prediction error within different refractive thresholds were calculated to assess the accuracy of each formula.In order to investigate the impact of AL on accuracy of IOL calculation,the patients were categorized into group A(38 eyes,26.00 mm＜AL≤28.00 mm),group B(28 eyes,28.00 mm＜AL≤30.00 mm),and group C(34 eyes,AL＞30.00 mm).Additionally,the patients were also divided into silicone oil(63 eyes)and non-silicone oil(37 eyes)groups based on preoperative intraocular filling to determine the effect of intraocular filling on IOL calculation.Results The MedAE values of the new-generation IOL formulas(BU Ⅱ,EVO,and Kane)were significantly lower(0.34D,0.31D,0.35D)than those of traditional formulas(P＜0.05).Additionally,the percentage of prediction errors within±0.25 D,±0.50 D,±0.75 D,and±1.00 D were significantly higher with the new formulas when compared to traditional ones(P＜0.05).Traditional formulas exhibited a hyperopic deviation(0.35D～0.65 D),which could be corrected using the WK eye axis adjustment.WK2 was effective in improving the accuracy of calculation in SRK/T and Holladay 1 formulas,and there was no statistical difference in the MedAE values of SRK/T-WK2 and Holladay 1-WK2 formulas with the new-generation IOL formulas.When comparing the formulas across different axial eye length groups in terms of MedAE,the new IOL formulas(BU Ⅱ,kane and EVO)and WK-corrected formulas(Haigis-WK1,SRK/T-WK 1,SRK/T-WK2,Hoffer Q-WK1,Holladay 1-WK1,Holladay 1-WK2)showed no significant differences among the different AL groups.However,there were significant differences in the MedAE values of traditional formulas among the different AL groups(P＜0.01),with group C displaying the largest MedAE values(Haigis:0.84D,SRK/T:1.10D,Hoffer Q:1.23D,Holladay 1:1.20D).Comparing the MedAE values of different formulas in various preoperative intraocular filling groups,it was observed that the MedAE values of the new-generation IOL formulas(BU Ⅱ,kane and EVO),Haigis,and SRK/T formulas were significantly higher in the silicone oil-filled eye group than the non-silicone oil-filled eye group(P＜0.05).Conclusion In patients with high myopia undergoing combined anterior and posterior segment surgery,the precision and consistency of the new-generation IOL formulas and the second-generation linear WK axis correction formula exhibit significant improvements when compared to traditional formulas.

Purpose To investigate the ultrasound features and classification of pilomatricoma and its correlation with pathological manifestations.Materials and Methods The clinical,ultrasound and pathological data of 76 patients(78 lesions)postoperative confirmed pilomatricoma in Henan Province Hospital of Traditional Chinese Medicine and the the First Affiliated Hospital of Henan University of Traditional Chinese Medicine from July 2014 to August 2021 were analyzed,retrospectively.According to the presence or absence of calcification and the pattern of calcification in the sonogram,they were divided into no calcification type,dotted calcification type,sheet calcification type and complete calcification type.Results Pilomatricoma were most common in children under 10,with predilection location in the face and head.Most lesions were surrounded by hypoechoic halo and calcification,51 of 78 lesions had different degrees of calcification,accounting for about 65.4%;36 lesions were with hypoechoic halo;63 lesions were mainly hypoechoic,accounting for about 80.8%.There were statistical differences in hypoechoic halo(χ2=15.624,P=0.001)and internal echo(χ2=12.801,P=0.021)among different classification pilomatricoma.Shadow cells and basicyte were detected in all 78 lesions,basophil cells were found in the periphery of 50 out of 54 lesions showing hypoechoic halos.The ultrasound manifestations of different types had characteristic changes corresponding to their pathological composition.Conclusion The ultrasound performance varies among the different types of pilomatricoma,and there is a correlation with its pathological changes.Familiarization with the sonographic presentation of pilomatricoma in the different types contributes to the preoperative diagnosis.

Objective To evaluate the efficacy of Broncho-Vaxom combined with physiological sea water nasal wash in the treatment of chronic rhinitis-rhinosinusitis in children. Methods A total of 179 children with chronic rhinitis-rhinosinusitis were randomly divided into observation group of 90 cases and control group of 89 cases. The observation group received treatment of oral administration of Broncho-Vaxom capsules at a dose of 3.5 mg once daily on an empty stomach in the morning for 10 consecutive days, with a 20-day drug-free period as one course of treatment, for a total of 3 courses. Additionally, they underwent nasal irrigation with physiological sea water twice daily in the morning and evening, for 10 consecutive days, with a 20-day break as one course of treatment, for a total of 3 courses. The control group underwent nasal irrigation with physiological sea water using the same method of the observation group. Both groups received symptomatic treatment such as anti-allergy therapy, and antibiotics were added when there presented obvious inflammatory changes. After treatment, the clinical total effective rate was compared between the two groups. Changes in the scores of Visual Analogue Scale (VAS) and Lund-Kenndy scale for nasal endoscopy, as well as changes in serum IgG, IgE, and T lymphocyte subsets were also compared. A six-month follow-up was conducted to assess the recurrence rate and average number of episodes of rhinosinusitis (times per person). Results The clinical total effective rate in the observation group was significantly higher compared to that in the control group(95.56% versus 86.52%). The scores of VAS and Lund-Kenndy scale in the observation group were significantly better than those in the control group. Serum IgG levels in the observation group were increased and higher than those in the control group, while serum IgE level in the observation group was decreased and lower than that in the control group. After 3 courses of treatment, the levels of CD3⁺, CD4⁺, and CD4⁺/CD8⁺ in the blood of the observation group were increased, while the level of CD8⁺ was decreased. The six-month follow-up after treatment showed that the recurrence rate of rhinitis-rhinosinusitis in the observation group was 17.05%, with an average of 0.28 episodes per person, which was lower than that in the control group (P < 0.05). Conclusion The combination of Broncho-Vaxom and physiological sea water nasal wash is effective in treating chronic rhinitis-rhinosinusitis in children, and can increase serum IgG level, decrease serum IgE level, optimize the structure of T lymphocyte subsets, enhance immune resistance, and improve allergic constitution. The six-month follow-up of the treatment reduces recurrence rate and average number of episodes of rhinitis-rhinosinusitis.

Arrhythmia is a significant cardiovascular disease that poses a threat to human health, and its primary diagnosis relies on electrocardiogram (ECG). Implementing computer technology to achieve automatic classification of arrhythmia can effectively avoid human error, improve diagnostic efficiency, and reduce costs. However, most automatic arrhythmia classification algorithms focus on one-dimensional temporal signals, which lack robustness. Therefore, this study proposed an arrhythmia image classification method based on Gramian angular summation field (GASF) and an improved Inception-ResNet-v2 network. Firstly, the data was preprocessed using variational mode decomposition, and data augmentation was performed using a deep convolutional generative adversarial network. Then, GASF was used to transform one-dimensional ECG signals into two-dimensional images, and an improved Inception-ResNet-v2 network was utilized to implement the five arrhythmia classifications recommended by the AAMI (N, V, S, F, and Q). The experimental results on the MIT-BIH Arrhythmia Database showed that the proposed method achieved an overall classification accuracy of 99.52% and 95.48% under the intra-patient and inter-patient paradigms, respectively. The arrhythmia classification performance of the improved Inception-ResNet-v2 network in this study outperforms other methods, providing a new approach for deep learning-based automatic arrhythmia classification.

AIM: To investigate the correlation between the ocular demodex infection and the composition of meibum lipid flora.METHODS: A non-interventional and observational study was performed on recruited 39 patients in our hospital between July 2020 and February 2021. They were divided into control group(n=14), meibomian gland dysfunction(MGD)group(n=14), and demodex group(FM, n=11)according to the presence or absence of demodex infection or MGD. High-throughput sequencing of V3-V4 fragment of 16S rRNA gene was performed on the meibomian ester samples of the three groups of subjects, and bioinformatics analysis was performed on the sequencing data to study the composition and difference of meibum lipid flora in the subjects of ocular demodex.RESULTS: Pseudomonas and Comamonas in FM group were significantly higher than those in control group and MGD group(P<0.05), while Ralstonia in Demodex infection group was significantly lower than that in control group and MGD group(P<0.05). The microbial richness and community diversity of meibum lipid flora of the MGD group and the FM group were significantly higher than those of the control group(P<0.05).CONCLUSION: Ocular demodex infection changed the composition of meibum lipid flora and increased the microbial richness and community diversity of meibum lipid flora.

OBJECTIVE: To explore the diagnostic yield of bronchoscopic rapid on-site evaluation (B-ROSE) in patients with severe invasive bronchopulmonary aspergillosis (IBPA) and provide evidence for starting antifungal treatment before microbiological results were available. METHODS: A prospective cohort study was conducted to select patients with severe pneumonia suspected of IBPA admitted to the respiratory intensive care unit (RICU) in the First Affiliated Hospital of Xinjiang Medical University from June 2014 to June 2022, and those who were primarily infected with other pathogens (such as bacteria, Mycobacterium tuberculosis) at admission were excluded. Whether the antifungal treatment was initiated or not on the basis of the bedside B-ROSE, the B-ROSE was administered as soon as possible within 24 hours after admission to RICU. The current international definition of invasive aspergillosis was used as the gold diagnostic standard, the diagnostic accordance rate, the sensitivity and specificity of B-ROSE were calculated respectively, and the receiver operator characteristic curve (ROC curve) was also plotted, to evaluate the predictive value in diagnosing IBPA. RESULTS: A total of 176 patients with severe pneumonia suspected of IBPA were included in the study. According to international diagnostic standards, there were 81 cases of IBPA and 95 cases of non-IBPA. According to the early diagnosis of B-ROSE, there were 89 cases of IBPA and 87 cases of non-IBPA. The diagnostic accordance rate of B-ROSE was 84.09% (148/176), the area under the ROC curve for B-ROSE in diagnosing severe IBPA was 0.844, the 95% confidence interval (95%CI) was 0.782-0.905, the sensitivity was 87.65%, the specificity was 81.05%, the positive predictive value was 79.78%, the negative predictive value was 88.51%, the rate of underdiagnosis was 12.35% (10/81), and the rate of misdiagnosis was 18.95% (18/95). Compared with the true negative group, the proportion of long-term (≥ 14 days) use of glucocorticoid [70.0% (7/10) vs. 9.1% (7/77), P < 0.01] and the proportion of cases with diabetes [40.0% (4/10) vs. 10.4% (8/77), P < 0.05] were significantly higher in the false negative group (underdiagnosis group). However, B-ROSE of both groups showed mucosal bleeding, congestion and edema [100.0% (10/10) vs. 94.8% (73/77), P > 0.05], indicating that acute mucosal inflammation was non-characteristic. Compared with the true positive group, the proportion of long-term (≥ 14 days) use of glucocorticoid in the false positive group (misdiagnosis group) was significantly reduced [33.3% (6/18) vs. 60.6% (43/71), P < 0.05]. The B-ROSE results showed the proportion of cases with mucosal white spots, black plaques and pseudomembrane was significantly reduced [16.7% (3/18) vs. 52.1% (37/71), P < 0.01] in the misdiagnosed group, which suggest that cases of long-term use of glucocorticoid and cases with B-ROSE showing mucosal white spots, black plaques and pseudomembrane were less likely to be misdiagnosed. The main diseases that were easily misdiagnosed as IBPA included pulmonary tuberculosis (38.9%, 7/18), inflammatory lung adenocarcinoma (27.8%, 5/18) and pulmonary vasculitis (16.7%, 3/18). CONCLUSIONS Before obtaining microbiological evidence, B-ROSE can assist in decision-making of early anti-aspergillus treatment for severe IBPA. This method is prompt, simple, and has high accuracy and reliability. If B-ROSE lacks characteristic manifestations, especially for severe pneumonia in patients with long-term use of glucocorticoid or diabetes, attention should be paid to the underdiagnosis of IBPA. Diseases such as lung tuberculosis, inflammatory lung adenocarcinoma and lung vasculitis should be vigilant against misdiagnosis as IBPA.
