To investigate the correlation between vitamin D nutritional status and insulin resistance in pubertal adolescents. This cross-sectional observational study employed convenience sampling to recruit 2021-grade(8th grade) students from Jining No.7 Middle School in Shandong Province on June 5, 2023. Data collection included questionnaires, physical examinations, and imaging assessments to obtain general information, secondary sexual characteristics development, and bone age. Venous blood samples were collected to measure fasting blood glucose(FBG), fasting insulin(FINS), homeostasis model assessment of insulin resistance(HOMA-IR), and 25-hydroxyvitamin D[25(OH)D] levels. Spearman correlation analysis and multivariate linear regression models were used to examine the associations between serum vitamin D levels and FBG, FINS, and HOMA-IR. The study included 168 pubertal adolescents[69 females(41.1%), 99 males(58.9%); mean age(13.27±0.46) years]. All participants had entered puberty based on sexual development assessment. Vitamin D deficiency was observed in 41 participants(24.4%), insufficiency in 109(64.9%), and sufficiency in 18(10.7%). The median HOMA-IR was 3.49(2.57, 5.14).Significant differences were found across vitamin D status groups for HOMA-IR [4.45(2.54, 6.62) Vitamin D deficiency/insufficiency is prevalent among pubertal adolescents, and serum vitamin D levels show a significant inverse association with insulin resistance. These findings suggest the potential importance of vitamin D status in metabolic health during puberty.

Acute kidney injury (AKI) is a critical clinical condition characterized by rapid renal function decline, with high morbidity, mortality, and healthcare costs. Traditional Chinese medicine (TCM) has shown potential effects on mitigating oxidative stress and programmed cell death in AKI models. Scutellaria barbata D. Don (SB) and Scleromitrion diffusum (Willd.) R. J. Wang (SD), a classic TCM herbal pair exhibited anti-inflammatory and antioxidant activities. Using advanced chromatographic separation technology, we enriched the effective fractions of water extracts from SB-SD, obtaining self-assembled herbal nanoparticles (SB and SD nanoparticles, SSNPs) rich in flavonoids and terpenoids. These SSNPs demonstrated robust antioxidant properties in vitro and mitigated AKI progression in vivo by activating the nuclear factor erythroid 2-related factor 2 (Nrf2) signaling pathway. Oral administration of SSNPs in mice resulted in absorption into the bloodstream, formation of a protein corona, reduced macrophage phagocytosis, and enhanced bioavailability and renal targeting. Furthermore, we investigated the self-assembly principle of SSNPs using representative flavonoids and terpenoids. Kinetic studies and in situ transmission electron microscopy (in situ TEM) revealed that these compounds self-assemble via supramolecular forces like hydrogen bonding and π-π interactions, forming stable nanostructures. This study elucidates the renoprotective effects and mechanisms of SB and SD, and provides a novel approach for the development of TCM-based nanomedicines, highlighting the potential of nano-TCM in AKI treatment.

Objective:
To investigate the present situation of health education on school myopia prevention and control in primary and middle schools in Beijing, so as to provide scientific basis and suggestions for effective implementation of health education on school myopia prevention and control.
Methods:
From November 6-17, 2023, a total of 551 school doctors and health care teachers from public primary and secondary schools in seven districts of Beijing were investigated by using stratified random cluster sampling method. The contents included basic information, the basic situation of school health work, and the status of myopia prevention and control in schools. The data was described by frequency and proportion. Chisquare test was used to analyze the influencing factors.
Results:
A total of 89.8% of the respondents were found in the school of offering health education courses about myopia prevention and control. Among these respondents, 54.5% were equipped with health education course material of professional myopia prevention and control, and the teachers were primarily class teachers (57.6%), health care teachers (45.5%), and physical education teachers (45.1%), and most of the classes were conducted once a month (33.7%) and once a semester (28.1%). A total of 95.6% of the subjects had health education activities about myopia prevention and control at their schools. The frequency of activities was once a month (38.5%) and once a semester (27.9%). There were statistically significant differences of the report rate in setting up health education courses on myopia prevention and control, and the frequency of activities in different areas and different types of schools (χ2=19.53, 13.15, 34.30, 20.32, P<0.05).
Conclusions
Health education on school myopia prevention and control in primary and middle schools in Beijing is supportive. But health education courses taught by professional teachers should pay attention to the norms of the course material to complete a certain amount of class time, and development of health education activities should be diversified, so as to effectively implement health education of myopia prevention and control at school.

BACKGROUND:Patients with degenerative cervical spondylosis often suffer from changed varicosity of the cervical spine,unbalanced neck-shoulder muscular strength,and descending power. OBJECTIVE:To probe into the correlation between sagittal curvature parameters and pain threshold for neck-shoulder muscles in degenerative cervical spondylosis. METHODS:Totally 50 patients with degenerative cervical spondylosis received treatment at the 3D Printed Outpatient Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2022 to March 2023 were included in the study.After excluding the 10 patients of cervical lateral projection that failed to meet the measurement conditions,the cervical lateral projections were shot to measure the following iconography parameters:Borden value and C2-7 Cobb angle as well as pain thresholds on the midpoint of the superior trapezius muscle in bilateral bundles and at 1 cm beside the C5-6 interspike.The correlation between sagittal curvature parameters and pain threshold of neck-shoulder muscles in degenerative cervical spondylosis was analyzed. RESULTS AND CONCLUSION:(1)The Borden value of sagittal curvature showed a moderately positive correlation with the bundle pain threshold in the left upper trapezius muscle,the bundle pain threshold in the right upper trapezius muscle,and the pain threshold at the 1 cm of the left side beside the C5-6 interspike(r=0.498,P<0.01;r=0.448,P<0.05;r=0.405,P<0.05)and a weak positive correlation with the pain threshold at the 1 cm of the right side beside the C5-6 interspike(r=0.322,P<0.05).(2)The C2-7 Cobb angle showed a weak positive correlation with the left squared myalgia threshold(r=0.355,P<0.05),and there was no correlation with the pain threshold of the left trapezius muscle and the pain threshold at the 1 cm of both sides beside the C5-6 interspike.(3)There was a correlation between the pain threshold of the neck-shoulder muscles,and a high correlation between the pain threshold of the left and right muscles and the pain threshold within the left and right side muscles,indicating that the neck-shoulder muscles are consistent and may be related to the coordination of the neck-shoulder movements.

BACKGROUND:The study of the lumbar spine and pelvis in patients with Lenke type 5 lordosis is limited to the coronal and sagittal planes,and the three-dimensional relationship between the scoliosis and the pelvis has not yet been clarified. OBJECTIVE:To analyze the effect of lumbar scoliosis on the pelvis in patients with Lenke type 5 lordosis and to study the correlation between the lumbar spine and the three-dimensional spatial position of the pelvis. METHODS:Imaging data of 60 patients with Lenke type 5 lordosis scoliosis admitted to the 3D Printing Reception Center of Shanghai Ninth People's Hospital,Shanghai Jiao Tong University School of Medicine from January 2019 to September 2023 were retrospectively analyzed,including Cobb angle,coronal pelvic tilt,lumbar lordosis,left and right pelvic hip width ratio(sacroiliac-anterior superior iliac spine),spinal rotation angle,pelvic tilt,sacral slope,pelvic incidence,coronal deformity angular ratio,sagittal deformity angular ratio,C7 plumb line-center sacral vertical line,apical vertebral translation,and coronal sacral inclination.The information was summarized as a database.SPSS 22.0 software was used to analyze the data related to the lumbar spine and pelvis of the patients with Lenke type 5 primary lumbar curvature adolescent idiopathic scoliosis using Spearman's correlation analysis and linear regression. RESULTS AND CONCLUSION:(1)Cobb angle was highly positively correlated with coronal deformity angular ratio,apical vertebral translation,and spinal rotation angle(r=0.91,r=0.841,r=0.736).(2)Coronal deformity angular ratio was highly positively correlated with apical vertebral translation(r=0.737),moderately positively correlated with C7 plumb line-center sacral vertical line(r=0.514),and moderately negatively correlated with sagittal deformity angular ratio(r=-0.595).(3)There was a high positive correlation between lumbar lordosis and sagittal deformity angular ratio(r=0.942)and a moderate negative correlation with coronal deformity angular ratio(r=-0.554).(4)There was a moderate positive correlation between Cobb angle with coronal pelvic tilt and coronal sacral inclination(r=0.522,r=0.534)and a moderate positive correlation between C7 plumb line-center sacral vertical line and coronal pelvic tilt(r=0.507).Apical vertebral translation with coronal pelvic tilt and coronal sacral inclination showed a moderate positive correlation(r=0.507,r=0.506).Lumbar lordosis with sacral slope and pelvic incidence showed a moderate positive correlation(r=0.512,r=0.538).Sagittal deformity angular ratio was moderately positively correlated with sacral slope and pelvic incidence(r=0.614,r=0.621).(5)Studies have found that the relative position of the lumbar spine and the pelvis is closely related in the horizontal,sagittal and coronal planes.When the lumbar spine affects scoliosis and is rotated,the relative position of the pelvis will also change to compensate,which indicates that while correcting scoliosis,the correction of the pelvis cannot be ignored.

BACKGROUND:Sepsis is one of the main causes of mortality in intensive care units(ICUs).Early prediction is critical for reducing injury.As approximately 36%of sepsis occur within 24 h after emergency department(ED)admission in Medical Information Mart for Intensive Care(MIMIC-IV),a prediction system for the ED triage stage would be helpful.Previous methods such as the quick Sequential Organ Failure Assessment(qSOFA)are more suitable for screening than for prediction in the ED,and we aimed to find a light-weight,convenient prediction method through machine learning. METHODS:We accessed the MIMIC-IV for sepsis patient data in the EDs.Our dataset comprised demographic information,vital signs,and synthetic features.Extreme Gradient Boosting(XGBoost)was used to predict the risk of developing sepsis within 24 h after ED admission.Additionally,SHapley Additive exPlanations(SHAP)was employed to provide a comprehensive interpretation of the model's results.Ten percent of the patients were randomly selected as the testing set,while the remaining patients were used for training with 10-fold cross-validation. RESULTS:For 10-fold cross-validation on 14,957 samples,we reached an accuracy of 84.1%±0.3%and an area under the receiver operating characteristic(ROC)curve of 0.92±0.02.The model achieved similar performance on the testing set of 1,662 patients.SHAP values showed that the five most important features were acuity,arrival transportation,age,shock index,and respiratory rate. CONCLUSION:Machine learning models such as XGBoost may be used for sepsis prediction using only a small amount of data conveniently collected in the ED triage stage.This may help reduce workload in the ED and warn medical workers against the risk of sepsis in advance.
