Objective: To investigate the current status of screening myopia and anxiety symptoms and associated factors among junior and senior high school students in Beijing, so as to provide evidence for myopia prevention and control and the improvement of mental health among adolescents. Methods: From September to November 2024, a total of 17 245 junior high schools, general senior high schools and vocational high schools from 16 districts in Beijing were enrolled by stratified cluster sampling method. Questionnaire surveys and vision screening were conducted to collect data on anxiety symptom and screening diagnosed myopia. The Chi square test was used to analyze the co-occurrence of myopia and anxiety symptoms, and binary Logistic regression analysis was adopted to explore the related factors of the co-occurrence. Results: The overall detection rate of cooccurrence screening myopia and anxiety symptoms among Beijing junior and senior high school students was 6.00%. The detection rate was higher in females ( 7.15 %) than in males (4.90%), higher in urban areas (6.65%) than in suburban areas (5.41%), and higher in general senior high school students (7.61%) than in vocational high school students (6.46%) and junior high school students (4.65%). All differences were statistically significant ( χ 2=38.49, 11.66, 54.88, all P <0.01). Binary Logistic regression analysis showed that female gender ( OR =1.43), general senior high school ( OR =1.60), vocational high school ( OR =1.59), daily sugar sweetened beverage intake ( OR =1.66), participation in academic extracurricular classes in preschool ( OR =1.30), electronic screen use for more than 2 hours per day ( OR =1.21), and insufficient sleep ( OR =2.41) were associated with an increased risk of co-occurring screening diagnosed myopia and anxiety symptoms (all P <0.05). Conclusions The co-occurrence of screening diagnosed of myopia and anxiety symptoms among junior and senior high school students in Beijing is common. Female gender, senior high school students, and unhealthy lifestyle behaviors are all risk factors for the co-occurrence of myopia and anxiety symptom. Comprehensive intervention measures can be adopted to simultaneously promote vision protection and mental health among junior and senior high school students.

Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Given the current ethical issues such as unknown high risks in the clinical application of new biomedical technology， thus， medical institutions need to establish new technology management systems， including clarifying the concept， the assessment and admission mechanism， and ethical management systems of new technology. According to the direction of the development of new technology in the medical institution， the ethics review committee should also perfect the management system of ethics committees and the professional composition of ethics review committee members， improve the ability of ethics committee members to evaluate new biomedical technology， increase the assessment of ethical risks of new technology in the preliminary review stage， strengthen the requirements for emergency plan formulation， as well as set the frequency of the follow-up review based on the risk level of new technology. The ethics review committee should work together with the medical management department to formulate an ethical standardization training system for the clinical application of medical technology in the institution， and regularly conduct training for all staff， to promote medical workers’ understanding of the management requirements of biomedical technologies. Different types of new biomedical technology have different ethical risks. Therefore， the medical management departments and ethics review committees of medical institutions should formulate specific management rules based on the characteristics of new technology types. However， it should be noted that when new biomedical technology generally is first introduced into clinical practice， there are often issues regarding fairness and justice in the use of the technology.

The anti-aging Klotho gene can not only delay the aging process but also regulate fibrosis and inflamma-tory responses by influencing inflammatory cells such as monocytes-macrophages,T cells,and B cells.It can regu-late the processes related to fibrosis and inflammatory responses through inflammatory pathways such as fibroblast growth factor(FGF),transforming growth factor-β(TGF-β),Toll-like receptor(TLR),nuclear factor-κB(NF-κB),and the renin-angiotensin system(RAS).Thus,elucidating the molecular mechanisms by which Klotho regulates inflammatory responses and fibrosis,and developing targeted intervention strategies to upregulate Klotho levels based on these mechanisms,may provide new theoretical basis and therapeutic targets for the prevention and treatment of related diseases.

ObjectiveTo explore the potential mechanism of Dingchuan Granule （定喘颗粒， DG） in the treatment of respiratory syncytial virus （RSV） pneumonia. MethodsA total of 60 male Sprague Dawley （SD） rats were randomly divided into control group， model group， ribavirin group， DG low-dose group， DG middle-dose group， and DG high-dose group， with 10 rats in each group. Except for the control group， rats were administrated with RSV via intranasal drip. After model establishment， the DG low-， middle-， and high-dose groups were administrated via oral gavage with DG at 3.47， 6.93， and 13.86 g/（kg·d） respectively， while the ribavirin group was administrated via oral gavage with ribavirin at 15.75 mg/（kg·d）. The drug was given once daily for one week. The rats in the control group and the model group were not given any drug， only subjected to the grasping action. Twenty-four hours after the last administration， the pathological changes of lung tissues were observed and scored using HE staining. The levels of serum inflammatory factors， including tumor necrosis factor-α （TNF-α）， interleukin-1β （IL-1β）， and interleukin-6 （IL-6）， were detected by colorimetry. The protein levels of nuclear factor （erythroid derived 2）-like 2 （Nrf2）， Kelch-like ECH-associated protein 1 （Keap1）， heme oxygenase 1 （HO-1）， and NAD（P）H quinone dehydrogenase 1 （NQO1） in lung tissues were measured by Western Blot. The RSV load as well as the gene expression levels of Nrf2， Keap1， HO-1， and NQO1 in lung tissues were determined by qRT-PCR. The level of reactive oxygen species （ROS） in rat lung tissues was detected using chemiluminescence. The levels of glutathione （GSH） and malondialdehyde （MDA） in rat lung tissues were measured by a microassay. ResultsCompared with the control group， other groups had significant increases in pathological score of lung tissue， RSV load， levels of ROS， MDA， serum TNF-α， IL-1β， and IL-6； decrease in GSH level， increases in expression level of Keap1 protein and its mRNA in lung tissue， and significant decrease in levels of Nrf2， HO-1， expression level of NQO1 protein and its mRNA （P＜0.05）. Compared with the model group， all the above-mentioned indicators in the DG low-， middle-， and high-dose groups and the ribavirin group were improved to varying degree （P＜0.05）. The levels of serum TNF-α， IL-1β， and IL-6 in rats of DG dose groups showed a dose-dependent pattern， the DG high-dose group exhibiting the best effect （P＜0.05）. The DG high-dose group was superior to the DG low- and middle-dose groups in reducing the levels of ROS and MDA， and increasing the level of GSH in lung tissues （P＜0.05）. The DG high-dose group and the ribavirin group had better effect than the DG middle-dose group in reducing the RSV load （P＜0.05）. The DG high-dose group was superior to the ribavirin group in improving the protein levels of Nrf2， Keap1， HO-1， and NQO1 （P＜0.05）. ConclusionDG could inhibit oxidative stress by regulating the Nrf2/Keap1/HO-1/NQO1 signaling pathway to improve pulmonary inflammation and treat RSV pneumonia， with the DG high-dose group showing the best effect.

ObjectiveTo investigate the feasibility and safety of endoscopic retrograde cholangiopancreatography （ERCP） combined with oral cholangiopancreatography in the treatment of major duodenal papilla gallbladder polyps. MethodsA retrospective analysis was performed for the clinical data of eight patients with choledocholithiasis and gallbladder polyps who underwent ERCP and combined with oral cholangiopancreatography for major duodenal papilla cholecystectomy in Center of Digestive Endoscopy， Jilin People’s Hospital， from May 2022 to June 2024， and related data were collected， including the success rate of surgery， the technical success rate of gallbladder polyp removal， the superselective method of cystic duct， the time of operation， the time of gallbladder polyp removal， and surgical complications. ResultsBoth the success rate of surgery and the technical success rate of gallbladder polyp removal reached 100%， and of all eight patients， three patients used guide wire to enter the gallbladder under direct view， while five patients received oral cholangiopancreatography to directly enter the gallbladder. The time of operation was 51.88±12.34 minutes， and the time of gallbladder polyp removal was 23.13±10.94 minutes. The diameter of gallbladder polyp was 2‍ ‍—‍ ‍8 mm， and pathological examination showed inflammatory polyps in three patients， adenomatous polyps in one patient， and cholesterol polyps in four patients. There were no complications during or after surgery. The patients were followed up for 2‍ ‍—‍ ‍27 months after surgery， and no recurrence of gallbladder polyp was observed. ConclusionOral cholangiopancreatography is technically safe and feasible in endoscopic major duodenal papilla cholecystectomy.

Objective:To establish 30-day of age transcutaneous bilirubin (TcB) reference curves for healthy neonates, and to investigate regional variations in bilirubin dynamics.Methods:A multicenter retrospective cohort study was conducted. A total of 220 950 healthy neonates born at a gestational age of 35-<42 weeks, with a birth weight ≥2 000 g, who did not receive phototherapy within 60 h after birth were recruited. All of them underwent remote TcB monitoring using the Bilibaby remote jaundice monitoring system between August 1 st, 2020 and December 31 st, 2024 in 426 hospitals. TcB data were collected within the period from birth to 30-day of age. The P40, P75, and P95 of TcB values were calculated, and dynamic TcB curves for 30-day of age were constructed. Patterns of bilirubin change, rates of change, and transition outcomes were described. Regional comparisons between South and North were conducted using linear mixed-effects models for TcB trajectories and Pearson′s chi-square test for outcome differences. Results:A total of 220 950 neonates were included, of whom 101 711 (46.03%) were female. Gestational age at birth was (38.75±1.12) weeks, and birth weight was (3 272±417) g. TcB levels increased rapidly within 3-day of age, peaked at 4-6-day of age, with peak values at P40, P75, and P95 of 200.6, 239.7 and 275.4 μmol/L (11.8, 14.1 and 16.2 mg/dl), respectively. TcB levels gradually declined thereafter and stabilized after 13-day of age, with values at P40, P75, and P95 fluctuating between 147.9-159.8, 190.4-200.6, and 231.2-239.7 μmol/L (8.7-9.4, 11.2-11.8, 13.6-14.1 mg/dl), respectively. Notably, among neonates categorized as low-or low-intermediate-risk within 3-day of age, 6 700 (12.76%) progressed to intermediate-high or high risk between 4 and 30 days of age. Before 13-day of age, TcB levels in the southern regions were consistently higher than those in the northern regions ( P=0.039); from 14 to 30 days of age, the overall TcB levels had no statistically difference, but the temporal changes in TcB still showed regional differences (degrees of freedom=3, all interaction P<0.05). Among neonates classified as low-or low-intermediate risk within 3-day of age, 25 326 were from southern regions, of whom 4 254 (16.80%) progressed to intermediate-high or high risk between 4 and 30 days of age. In northern regions, 27 193 neonates were classified as low-or low-intermediate risk within 3-day of age, among whom 2 446 (8.99%) progressed to intermediate-high or high risk. The risk progression between the 2 regions had statistically difference ( χ2=716.49, P<0.001). Conclusions:A TcB percentile curve for neonates within 30-day of age was established, revealing that both the overall TcB level and its temporal trend were higher in southern than in northern newborns. These findings provide baseline data to support continuous management of neonatal jaundice.

To enhance the practical ability and job competency of full-time master of public health (MPH) postgraduates and explore a collaborative training mode that integrates medical education with a prevention-and-control approach, in line with standardized public health physician training, the Beijing Center for Disease Control and Prevention, in collaboration with the School of Public Health affiliated to Capital Medical University, had recruited full-time MPH postgraduates since 2015. These students were trained and assessed through a collaborative training mode based on the Beijing public health physician training mechanism. Through the introduction and analysis of the training objectives, training process, practical assessment methods, training quality, and results, this article suggests that the construction of a collaborative training mode integrating MPH postgraduate education of public health professionals and standardized public health physician training has explored a new pathway for cultivating "four-certification integration" public health professionals. This aligns with the Chinese national strategy for public health talent development and can alleviate the problems of "contradictions between work and study", including the current shortage of public health physicians at present and the difficulties in standardized training enrollment. In addition, this collaborative training mode provides valuable experience for other medical schools in training applied public health professionals who meet national public health standards and combine prevention with treatment.
