Objective: To explore the association of outdoor activity time and sleep duration with screening myopia in primary school students, so as to provide strategies for myopia prevention. Methods: Through a convenience sampling method, a survey was conducted among 4 248 primary school students aged 7-13 years from three primary schools in Xihu District, Nanchang City, Jiangxi Province from May to July, 2023. The average daily outdoor activity time and sleep duration on both weekdays and weekends were investigated in primary school students by using a self designed questionnaire. Uncorrected visual acuity tests and non cycloplegic autorefraction were measured by professional optometrists. Inter group comparisons were conducted using the Chi square test. Logistic regression model was used to analyze the association of outdoor activity time and sleep duration with screening myopia. Results: The detection rate of screening myopia in primary school students was 33.6%, with the rate in boys (32.0%) lower than that in girls (35.3%), and the difference was statistically significant ( χ 2=5.11, P =0.02). The analysis results of Logistic regression showed that after adjusting for factors such as gender, grade and parental education level, both average daily outdoor activity time ＜2 h on both weekdays and weekends ( OR =1.27, 95% CI =1.11-1.46) and sleep duration <10 h ( OR =1.17, 95% CI =1.01- 1.35 ), as well as their combined effect ( OR =1.57, 95% CI =1.25-1.98), were associated with an increased risk of screening myopia in primary school students(all P <0.05). Subgroup analysis results indicated that compared to boys ( OR =1.46, 95% CI = 1.07 -1.99), girls( OR =1.73, 95% CI =1.22-2.44) with insufficient outdoor activity time and sleep duration had a higher risk of screening myopia(both P <0.05). Conclusions There is a negative correlation of outdoor activity time and sleep duration with screening myopia in primary school students. Outdoor activity time and extending sleep duration should be increased to reduce the risk of myopia in primary school students.

Anti-CD20 monoclonal antibodies for the treatment of refractory nephrotic syndrome （RNS） in children. The first- generation rituximab is the most widely used in clinical practice； it shows definite efficacy in children with RNS， is recommended by guidelines， particularly for achieving a high remission rate in minimal change nephrosis， and can significantly reduce the cumulative use of glucocorticoids and immunosuppressants. The second-generation ofatumumab has potential as an alternative treatment for patients who are intolerant or resistant to rituximab， while the third-generation obinutuzumab has shown efficacy in complex cases such as rituximab resistance or post-transplant recurrence. However， there is still controversy regarding the optimization of rituximab treatment dosage and whether ofatumumab and obinutuzumab offer greater advantages than rituximab for the treatment of RNS in children. The most common adverse reaction induced by anti-CD20 monoclonal antibodies is infusion reactions， and long-term adverse events mainly include increased risks of sustained immunosuppression and infections. Rituximab has significant economic advantages for the treatment of RNS， but additional pharmacoeconomic research based on China’s healthcare environment is needed to evaluate the cost-effectiveness of ofatumumab and obinutuzumab in this population. Given that the current use of ofatumumab and obinutuzumab in this field is considered off-label use， clinical application should only proceed after a rigorous evaluation of the patient’s benefits and risks.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Metastatic dissemination is the major cause of death from breast-cancer (BC). Fusobacterium nucleatum (F.n) is widely enriched in BC and has recently been identified as one of the high-risk factors for promoting BC metastasis. Here, with an experimental model, we demonstrated that intratumoral F.n induced BC aggressiveness by transcriptionally activating Epithelial-mesenchymal transition-associated genes. Therefore, the F.n may be a potential target to prevent metastasis. Given the fact that cancer-associated fibroblasts (CAFs) are abundant in BC and located near blood vessels, we report an optogenetic system that drives CAF to in situ produce human antibacterial peptide LL37, with the characteristics of biosafety and freely intercellular trafficking, for depleting intratumoral F.n, leading to a 72.1% reduction in lung metastatic nodules number without affecting the balance of the systemic flora. Notably, mild photothermal treatment was found that could normalize CAF, contributing to synergistically inhibiting BC metastasis. In addition, the system can also simultaneously encode a gene of TNF-related apoptosis-inducing ligand to suppress the primary tumor. Together, our study highlights the potential of local elimination of tumor pathogenic bacteria to prevent BC metastasis.

Objective:To evaluate the clinical efficacy of Cai's gynecological nourishing kidney therapy for patients with diminished ovarian reserve (DOR).Methods:A randomly controlled trail was conducted. A total of 63 patients with DOR who were treated in the gynecology outpatient clinic of Yueyang Hospital of Integrated Traditional Chinese and Western Medicine affiliated to Shanghai University of Traditional Chinese Medicine from September 2020 to January 2022 were set as observation subjects, and were divided into control group ( n=31) and observation group ( n=32) according to the random number table method. The patients in the control group were treated with Femoston, and the patients in the observation group were treated with Cai's gynecological nourishing kidney therapy on the basis of Femoston treatment. Both groups were treated for 3 menstrual cycles. Both antral follicle count (AFC) was performed by vaginal ultrasound, serum levels of TGF-β1, IL-1β, IL-2, IL-6 and IL-21 were detected by ELISA, and serum levels of FSH, LH, E2, anti-Müllerian hormone (AMH) and MDA were detected by biochemical methods. The TCM syndrome score was used to evaluate the severity of symptoms, and the menstrual score was used to evaluate the abnormal menstruation. Clinical efficacy was evaluated. Results:The total effective rate was 87.50% (28/32) in the observation group and 58.06% (18/31) in the control group, with statistical significance ( χ2=8.42, P=0.004). After treatment, the AFC in the observation group (3.93±2.32 vs. 2.21±2.18, t=3.03) was higher than that of the control group ( P<0.01). After treatment, the serum FSH level of the observation group [10.05 (8.35, 21.48) IU/L vs. 20.60 (8.00, 43.30) IU/L, Z=2.18] was lower than that of the control group ( P<0.05), and the level of AMH [0.19 (0.03, 0.47) μg/L vs. 0.02 (0.01, 0.24) μg/L, Z=-1.54] in the observation group was higher than that of the control group ( P<0.05). The serum levels of TGF-β1 [(68.27±11.76) ng/L vs. (55.33±13.03) ng/L, t=4.14] and IL-1β [(58.00±7.53) ng/L vs. (52.31±8.06) ng/L, t=2.89] in the observation group were higher than those in the control group, and the levels of IL-6 [(33.26±7.45) ng/L vs. (40.69±11.69) ng/L, t=3.02], the level of IL-21 [(118.37±15.56) ng/L vs. (140.43±25.51) ng/L, t=-4.04] was lower than that of the control group ( P<0.01). Conclusions:Cai's gynecological nourishing kidney therapy combined with Fenmaotong can effectively increase the AFC of DOR patients and improve clinical efficacy. Its mechanism of action may be related to reducing serum FSH and LH levels and increasing E2 levels.

Objective:To investigate the association of white matter hyperintensities (WMHs) with long-term stroke recurrence in patients with recent subcortical small infarcts (RSSIs).Methods:Consecutive patients admitted to the Department of Neurology, Hefei Hospital Affiliated to Anhui Medical University between January 2019 and August 2022 and met the clinical and imaging manifestations of RSSIs were collected. The demographic characteristics, baseline clinical data, and MRI features were collected. Using stroke recurrence as the endpoint event, the recurrence time was recorded, and Cox regression model was used to analyze relevant factors affecting stroke recurrence in patients with RSSIs.Results:A total of 202 patients were enrolled, including 138 males (68.3%), aged 67.9±10.5 years. Seventy-seven patients (38.1%) were mild WMHs, 64 (31.7%) were moderate WMHs, and 61 (30.2%) were severe WMHs. There were statistically significant differences in age, history of stroke, hypertension, hyperlipidemia, total cholesterol, infarct thickness, and infarct distribution among different WMHs severity groups (all P<0.05). The median follow-up time was 40.5 months (interquartile range, 27.7-49.0 months), and a total of 55 patients (27.2%) had stroke recurrence (ischemic stroke 54, occipital hemorrhage 1). Recurrence rates of stroke in the mild, moderate, and severe WMHs groups were 18.2%, 31.3%, and 34.4%, respectively. Cox regression analysis showed that WMHs were an independent risk factor for stroke recurrence (compared to the mild group, the risk ratio of the severe group was 2.225, 95% confidence interval was 1.116-4.436; P=0.023). Conclusion:The risk of long-term stroke recurrence in patients with RSSI is associated with the severity of WMHs.

Objective:To explore the genetic etiology and clinical phenotype of Feingold syndrome due to chromosome 2p24.3p24.2 microdeletion.Methods:The clinical data of a child admitted to Henan Provincial People′s Hospital in November 2021 and diagnosed as Feingold syndrome type 1 (FGLDS1) associated with chromosome 2p24.3p24.2 microdeletion were collected. The clinical and genetic variation characteristics of the patient were summarized, and 10 patients with chromosome 2p microdeletion reported until November 2022 were reviewed.Results:The boy was 12 years and 5 months old. He presented with backward physical development, motor development retardation, low intelligence, special body and facial appearance, finger developmental deformity and other manifestations, accompanied by hyperactivity and aggressive behavior, impulsive irritability, self-injury and other behavior problems. The proband showed normal chromosome karyotype; the genome-wide copy number variant sequencing and trio-whole exome sequencing revealed a 2.61 Mb deletion at chromosome 2p24.3p24.2 region, and 10 genes including MYCN gene (exons 1 to 3) in the deleted region.The same deletion was not found in either of his parents. The genetic features of 11 cases (including this case) with chromosome 2p microdeletion were summarized, all of whom had insufficient haploid dosage of the MYCN gene due to chromosome 2p microdeletion, and the clinical manifestations of these 11 patients matched the clinical diagnosis of FGLDS1. Conclusion:The proband is consistent with the clinical presentation of the typical Feingold syndrome, and the haploinsufficiency of the MYCN gene due to the microdeletion of chromosome 2 is the genetic etiology of the proband.
