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 analyze the influencing factors of substandard steady state blood trough concentration of meropenem in the first monitoring.Methods Patients who were treated with meropenem and monitored steady-state blood trough concentration from July 2021 to June 2023 in the First Affiliated Hospital of Xi'an Jiaotong University were selected as the study subjects,and the patient's age,gender,and other medical history data were recorded.The steady-state blood trough concentration of meropenem was determined and the target was identified.According to the monitoring results,the patients were categorized into the standard group(2.0-16.0 mg·L-1)and non-standard group(＜2.0 mg·L-1 in the low concentration group and＞16.0 mg·L-1 in the high concentration group).Univariate and multivariate logistic regression analyses of relevant variables were performed for the low and high concentration groups,respectively,compared with the standard group to screen for risk factors for substandard steady-state trough concentration of meropenem.Results A total of 324 patients were included,there were 189 cases(58.33％)were reached the standard concentration,while 135 cases(41.67％)were failed to meet the standard(86 cases in low concentration group and 49 cases in high concentration group).The results of multivariate logistic regression analysis showed that glomerular filtration rate(P＜0.05),abumin(P＜0.05)and craniocerebral diseases(P＜0.05)were risk factors in the low concentration group compared with the standard group,the glomerular filtration rate of patients with brain injury was significantly higher than patients without brain injury;cystatin-C(P＜0.05)was a protective factor for the concentration of meropenem in both groups.The daily dose of meropenem(P＜0.05)and procalcitonin(P＜0.05)were risk factors for high meropenem blood concentrations in the high-concentration group compared with the standard group,whereas glomerular filtration rate(P＜0.05)was ta protective factor for the concentration of meropenem in the two groups.Conclusion Glomerular filtration rate,albumin and brain injury were risk factors for low steady-state blood trough concentrations of meropenem,whereas daily dose of meropenem and procalcitonin of meropenem were risk factors of high steady-state blood trough concentrations of meropenem.

Autoantibody-related congenital heart block (ACHB) is a passively acquired autoimmune disease developing in fetuses after exposuring to maternal anti-Ro/Sj?gren's syndrome type A (SSA) antibody and/or anti-La/SSB antibody transported across the placenta, which contributes to fetal heart conduction system damage and signal conduction block at the atrioventricular node. However, fetal atrioventricular block does not necessarily occur with the presence of maternal autoantibodies, indicating its complex pathogenesis. This review focuses on the theories of calcium channels and apoptosis, the influence of other maternal factors and environmental changes on ACHB and the roles of natural killer cells and human leukocyte antigen in ACHB, aiming to provide reference for further study on the pathogenesis.
