Objective: To analyze the potential categories and influencing factors of the compliance trajectory of orthokeratology lenses (OK lens) in myopic children and adolescents, so as to provide a basis for dynamic and accurate intervention of OK lens compliance in myopic children and adolescents. Methods: From January to June 2024, 310 myopic children and adolescents wearing OK lens were selected as research subjects from the Ophthalmology Medical Center of Cangzhou Central Hospital using a convenient sampling method. Data were collected at four time points: when the glasses were first fitted (T0), 2 weeks after fitting (T1), 1 month later (T2), 3 months later (T3), and 6 months later (T4). The data collection methods included general information questionnaires, compliance surveys for OK lens wearers, the Behavior Rating Inventory of Executive Function-Self-report Version (BRIEF-SR), family support scales, and a self-made questionnaire on myopia control attitudes. A growth mixed model was used to identify the trajectory categories of compliance with OK lens wearing among myopic children and adolescents, and multiple Logistic regression analysis was employed to examine the influencing factors. Results: The compliance with OK lens among myopic children and adolescents were roughly divided into four developmental trajectories: C1 exemplary adherent (58 cases, 18.71%), C2 gradual progressor (130 cases, 41.94%), C3 fluctuating (85 cases, 27.42%), and C4 stubborn low follower (37 cases, 11.94%). Multivariate Logistic regression analysis showed that, with C1 group as the reference, age (C3, OR = 0.74 ), parental education level (C4, OR =0.67), executive function (C2, OR =0.69; C4, OR =0.44), family support (C3, OR =0.75) and myopia control attitude (C2, OR =0.39) were all influencing factors for the compliance trajectory of OK lens; with C2 group as the reference, age (C3, OR = 0.55 ), parental education level (C3, OR =0.34; C4, OR =0.64), executive function (C3, OR =0.77), and family support (C4, OR =0.58) were all influencing factors for the compliance trajectory of OK lens; with C3 group as the reference, age (C4, OR = 0.68 ), and myopia control attitude (C4, OR =0.44) were both influencing factors for the compliance trajectory of OK lens ( P <0.05). Conclusions The compliance of wearing OK lens in children and adolescents with myopia can be roughly divided into four trajectories, and there is group heterogeneity. Dynamic and precise compliance intervention strategies should be given based on different trajectories and influencing factors.

OBJECTIVE: To propose a machine learning-based method for predicting the trajectories during manual acupuncture manipulation (MAM), aiming to improve the precision and consistency of acupuncture practitioner' operation and provide the real-time suggestions on MAM error correction. METHODS: Computer vision technology was used to analyze the hand micromotion when holding needle during acupuncture, and provide a three-dimensional coordinate description method of the index finger joints of the holding hand. Focusing on the 4 typical motions of MAM, a machine learning-based MAM trajectory predictive model was designed. By integrating the changes of phalangeal joint angle and hand skeletal information of acupuncture practitioner, the motion trajectory of the index finger joint was predicted accurately. Besides, the roles of machine learning-based MAM trajectory predictive model in the skill transmission of acupuncture manipulation were verified by stratified randomized controlled trial. RESULTS: The performance of MAM trajectory predictive model, based on the long short-term memory network (LSTM), obtained the highest stability and precision, up to 98%. The learning effect was improved when the model applied to the skill transmission of acupuncture manipulation. CONCLUSION The machine learning-based MAM predictive model provides acupuncture practitioner with precise action prediction and feedback. It is valuable and significant for the inheritance and error correction of manual operation of acupuncture.

OBJECTIVE: To investigate the effect of manual acupuncture manipulations (MAMs) on subcutaneous muscle tissue, by developing quantitative models of "lifting and thrusting" and "twisting and rotating", based on machine learning techniques. METHODS: A depth camera was used to capture the acupuncture operator's hand movements during "lifting and thrusting" and "twisting and rotating" of needle. Simultaneously, the ultrasound imaging was employed to record the muscle tissue responses of the participants. Amplitude and angular features were extracted from the movement data of operators, and muscle fascicle slope features were derived from the data of ultrasound images. The dynamic time warping barycenter averaging algorithm was adopted to align the dual-source data. Various machine learning techniques were applied to build quantitative models, and the performance of each model was compared. The most optimal model was further analyzed for its interpretability. RESULTS: Among the quantitative models built for the two types of MAMs, the random forest model demonstrated the best performance. For the quantitative model of the "lifting and thrusting" technique, the coefficient of determination (R²) was 0.825. For the "twisting and rotating" technique, R² reached 0.872. CONCLUSION Machine learning can be used to effectively develop the models and quantify the effects of MAMs on subcutaneous muscle tissue. It provides a new perspective to understand the mechanism of acupuncture therapy and lays a foundation for optimizing acupuncture technology and designing personalized treatment regimen in the future.

Hearing loss is the most prevalent disabling disease. Cochlear implantation（CI） serves as the primary intervention for severe to profound hearing loss. This consensus systematically explores the value of genetic diagnosis in the pre-operative assessment and efficacy prognosis for CI. Drawing upon domestic and international research and clinical experience, it proposes an evidence-based medicine three-tiered prognostic classification system（Favorable, Marginal, Poor）. The consensus focuses on common hereditary non-syndromic hearing loss（such as that caused by mutations in genes like GJB2, SLC26A4, OTOF, LOXHD1） and syndromic hereditary hearing loss（such as Jervell & Lange-Nielsen syndrome and Waardenburg syndrome）, which are closely associated with congenital hearing loss, analyzing the impact of their pathological mechanisms on CI outcomes. The consensus provides recommendations based on multiple round of expert discussion and voting. It emphasizes that genetic diagnosis can optimize patient selection, predict prognosis, guide post-operative rehabilitation, offer stratified management strategies for patients with different genotypes, and advance the application of precision medicine in the field of CI.

Objective The aim of this study was to investigate the prospective association between physical activity (PA),independently or in conjunction with other contributing factors,and osteoporosis (OP) outcomes. Methods The Physical Activity in Osteoporosis Outcomes (PAOPO) study was a community-based cohort investigation. A structured questionnaire was used to gather the participants' sociodemographic characteristics. Bone mineral density (BMD) measurements were performed to assess OP outcomes,and the relationship between BMD and OP was evaluated within this cohort. Results From 2013 to 2014,8,471 participants aged 18 years and older were recruited from Tangshan,China's Jidong community. Based on their PA level,participants were categorized as inactive,moderately active,or very active. Men showed higher physical exercise levels than women across the activity groups. BMD was significantly higher in the very active group than in the moderately active and inactive groups. Individuals aged>50 years are at a higher risk of developing OP and osteopenia. Conclusion The PAOPO study offers promising insights into the relationship between PA and OP outcomes,encouraging the implementation of PA in preventing and managing OP.

Objective To investigate the dietary patterns of rural residents in the high-incidence areas of esophageal cancer (EC), and to explore the clustering and influencing factors of risk factors associated with high-incidence characteristics. Methods A special structured questionnaire was applied to conduct a face-to-face survey on the dietary patterns of rural residents in Yanting county of Sichuan Province from July to August 2021. Univariate and multivariate logistic regression models were used to analyze the influencing factors of risk factor clustering for EC. Results There were 838 valid questionnaires in this study. A total of 90.8% of rural residents used clean water such as tap water. In the past one year, the people who ate fruits and vegetables, soybean products, onions and garlic in high frequency accounted for 69.5%, 32.8% and 74.5%, respectively; the people who ate kimchi, pickled vegetables, sauerkraut, barbecue, hot food and mildew food in low frequency accounted for 59.2%, 79.6%, 68.2%, 90.3%, 80.9% and 90.3%, respectively. The clustering of risk factors for EC was found in 73.3% of residents, and the aggregation of two risk factors was the most common mode (28.2%), among which tumor history and preserved food was the main clustering pattern (4.6%). The logistic regression model revealed that the gender, age, marital status and occupation were independent influencing factors for the risk factors clustering of EC (P<0.05). Conclusion A majority of rural residents in high-incidence areas of EC in Yanting county have good eating habits, but the clustering of some risk factors is still at a high level. Gender, age, marital status, and occupation are influencing factors of the risk factors clustering of EC.

Objective:To explore the effects of Undaria pinnatifida polysaccharides(UPPs)on depressive-like behavior,neurotransmitter content,oxidative stress,and the hypothalamus-pituitary-adrenal(HPA)axis in rats treated with chronic unpredictable mild stress(CUMS).Methods:A rat model of depression was prepared using the CUMS method,and rats were treated with normal saline(NS)or different doses of UPPs by gavage.The general condition of the rats was observed,and depressive-like behavior was detected by the open field test(OFT),sucrose preference test(SPT),and forced swimming test(FST).The activity or levels of 5-hydroxytryptamine(5-HT),dopamine(DA)and norepinephrine(NE),malondialdehyde(MDA),superoxide disidase(SOD)and catalase(CAT),adrenocorticotrop-ic hormore(ACTH),corticosterone(CORT)in the hippocampus or serum of rats were detected using commercial kits.Western Blot was used to detect the expression level of hippocampal glucocorticoid receptor(GR)protein,and hema-toxylin-eosin(HE)staining was used to observe the tissue structure of hippocampus of rats.Results:The depressive-like behavior of rats in the UPPs medium and high dose groups was significantly improved(P＜0.05).In the UPPs high dose group,the contents of 5-HT,DA,and NE in the hippocampus of rats increased(P＜0.05),while the con-tents of MDA in both serum and hippocampus decreased(P＜0.05),and the activities of SOD and CAT increased(P＜0.05).The contents of ACTH and CORT in serum decreased(P＜0.05).In the UPPs medium dose group,the levels of hippocampal MDA and CAT,as well as serum SOD,ACTH,and CORT were improved(P＜0.05).The expression level of GR protein in the hippocampus increased(P＜0.05),and the pathological changes in the hipp-ocampal dentate gyrus were significantly improved.Conclusion:UPPs can alleviate depressive-like behavior in CUMS rats,and its mechanism may be related to increasing the content of monoamine neurotransmitters in the hippocampus,reducing oxidative stress damage,and HPA axis hyperfunction.
