Objective: To investigate the associations between 24 hour activity and the quality of life (QoL) in children with autism spectrum disorder (ASD), and to explore their isotemporal substitution effects, providing a reference for developing intervention strategies of their QoL. Methods: From March to June 2025, 288 children with ASD from 7 special education schools in Jinan were selected by using a cluster random sampling method. The 24 hour activity was measured by using ActiGraph wGT3X-BT triaxial accelerometers, and their QoL was assessed by applying a parent proxy Pediatric Quality of Life Inventory. Multiple linear regression was employed to analyze the associations between 24 hour activity and QoL in children with ASD. Isotemporal substitution analysis was applied to analyze the dose response relationship of 24 hour activity time and the QoL scores in children with ASD. Results: Within the 24 hour activities of children with ASD, the daily time spent in sleep, sedentary behavior (SB), light physical activity (LPA), and moderate to vigorous physical activity (MVPA) were 610.49，605.80，195.49，28.22 minutes, respectively. Multiple linear regression analysis showed that, after controlling for confounding factors such as gender, age, and parental education level, the proportion of time spent in MVPA was positively associated with QoL scores ( β =1.75) in children with ASD, whereas the proportion of time spent in SB was negatively associated with QoL scores ( β =-1.00)(both P <0.01). In the dose response relationship, reallocating time from sleep, SB, and LPA to MVPA was associated with an improvement in QoL in children with ASD, with increased scores of 1.38, 1.55, 1.47, respectively; conversely, the reverse substitution was associated with a decline in QoL, and the scores decreased by 2.31, 2.99 and 2.68, respectively, with the latter demonstrating a more pronounced effect(all P <0.05). Conclusions Enhancing the QoL for children with ASD should be grounded in the overall balance of 24 hour activity. Time reallocation strategies should be implemented with an emphasis on relatively increasing MVPA and reducing SB.

Atherosclerosis and its complications are one of the diseases with the highest incidence and mortality in the world,and its early diagnosis and treatment are very important.At present,a variety of physiological and biochemical indicators have been used to diagnose atherosclerosis.However,the accuracy and ease of use of existing diagnostic indi-cators still cannot meet the clinical needs,and new,reliable and easy to measure biomarkers for early diagnosis and judg-ment of atherosclerosis and the risk of serious cardiovascular and cerebrovascular events caused by atherosclerosis are still very scarce.This article summarized the latest research progress of biomarkers related to atherosclerosis,such as hematol-ogy,genetics and omics,in order to provide basis for early diagnosis and treatment of atherosclerosis and related cardiovas-cular and cerebrovascular diseases induced by atherosclerosis.

Objective:To investigate the intervention effect of five elements music of traditional Chinese medicine and western classical music on the sleep quality of stroke patients, and to compare the difference between the two, to provide a reference for the clinical care measures to improve the sleep quality of stroke patients.Methods:By adopting a randomized controlled trial, 75 stroke patients who were hospitalized in the rehabilitation hospital of the Second Affiliated Hospital of Shandong University of Traditional Chinese Medicine from July 2022 to July 2023 were selected by convenience sampling method as the study subjects, and the patients were randomly divided the conventional treatment group, the five-element music group, and the classical music group according to the method of randomized numerical table with 25 cases in each group. On the basis of general treatment, the conventional treatment group took sleep health education, the five elements music group were given five-element music intervention based on conventional treatment, and the classical music group were given classical music intervention based on conventional treatment. The changes of Athens Insomnia Scale (AIS), Pittsburgh Sleep Quality Index (PSQI) and polysomnography (PSG) examination parameters in the 3 groups were compared.Results:There were 2 cases of shedding in the conventional treatment group, and 23 cases were finally included, 15 males and 8 females, aged (54.02 ± 7.80) years; there were no cases of shedding in the five-element music group, and 25 cases were finally included, 12 males and 13 females, aged (53.69 ± 6.02) years; and there was 1 case of shedding in the classical music group, and 24 cases were finally included, 10 males and 14 females, aged (52.34 ± 7.08) years. Comparison of AIS, PSQI and PSG scores among the 3 groups of patients before intervention showed no statistically significant differences (all P>0.05). After the intervention, the AIS scores and PSQI scores of the 3 groups were (9.48 ± 1.53) and (12.22 ± 2.94), (6.76 ± 1.36) and (7.64 ± 2.08), (7.46 ± 1.38) and (10.33 ± 2.82), respectively, and the differences were statistically significant ( F=23.21, 18.44, both P<0.05). PSG sleep structure parameters showed that the total sleep time, REM latency time and sleep efficiency of the patients in the five-element music group after the intervention were (399.89 ± 51.76) min, (136.26 ± 25.36) min, (78.87 ± 8.21)%, higher than (368.45 ± 47.88) min, (124.46 ± 26.25) min, (73.36 ± 7.86)% in the classical music group and (345.48 ± 38.69) min, (111.37 ± 23.23) min, (69.44 ± 7.88)% in the conventional treatment group, and the differences between three groups were statistically significant ( F=8.27, 5.93, and 8.49, all P<0.05); the sleep latency time, awakening time, and number of awakenings in the five-element music group were (28.86 ± 17.68) min, (54.37 ± 25.15) min, and (2.72 ± 1.19) times, respectively, which were lower than those in the classical music group (35.67 ± 16.99) min, (64.28 ± 29.34) min, and (3.67 ± 1.12) times and (42.38 ± 18.96) min, (78.38 ± 37.26) min, (4.87 ± 1.46) times in the conventional treatment group, and the differences between three groups were statistically significant ( F=3.51, 3.66, and 17.56, all P<0.05). The results of the PSG sleep progression showed that the duration of the N1 stage of sleep in the five-element music group after the intervention was (95.71 ± 15.23) min, which was higher than (83.20 ± 18.34) min in the classical music group and (80.93 ± 16.47) min in the conventional treatment group, and the difference between three groups was statistically significant ( F=5.53, P<0.01); the N3 stage sleep time and the sleep percentage of the five-element music group after the intervention were respectively (84.23 ± 20.98) min and (23.98 ± 5.89)%, which were higher than (65.33 ± 18.82) min and (18.34 ± 3.78)% in the classical music group and (45.87 ± 18.65) min and (15.03 ± 5.56)% in the conventional treatment group, and the differences between three groups were statistically significant ( F=23.08, 18.50, both P<0.05). Conclusions:Both five elements music and classical music can improve the sleep quality of stroke patients, and the effect of five elements music to improve sleep is more significant.

OBJECTIVE To compare the long-term cost-effectiveness of gonadotrophin-releasing hormone analogue (GnRHa) combined with recombinant human growth hormone (rhGH) (combination therapy regimen) versus GnRHa monotherapy (monotherapy regimen) in the treatment of central precocious puberty (CPP).METHODS From the societal perspective and based on a real-world study conducted at West China Second Hospital of Sichuan University,the cost-effectiveness analysis was performed to compare the long-term cost-effectiveness of two pharmacotherapy regimens for CPP girls,with final height as outcome indexes,using per capita disposable income of rural residents and urban residents (20133-49283 yuan) in 2022 as the social willing-to-pay (WTP) threshold.The robustness of the basic analysis result was verified by using one-way sensitivity analysis and probability sensitivity analysis,and the cost-effectiveness of different combinations of long-acting preparations was compared using scenario analysis.RESULTS The basic analysis result showed that the combination therapy regimen required an additional cost of 25193.49 yuan for every one-centimeter improvement in the final height of girls with CPP compared with the monotherapy regimen,which was not cost-effective for residents in rural areas,but it was cost-effective for residents in urban areas.One-way sensitivity analysis showed that the uncertain factors with potential impacts on the results were,in order,the price of rhGH,the final height of pediatric patients in the combination therapy regimen group,the course of rhGH in the combination therapy regimen group,and the final height of pediatric patients in the monotherapy regimen group.Probabilistic sensitivity analysis indicated that the probability of the combination therapy regimen being cost-effective was higher than that of the monotherapy regimen when WTP was more than 26010 yuan/cm.When GnRHa long-acting preparation was used for intramuscular injection every 3 months,the combination therapy regimen was not cost-effective for rural residents,but was cost-effective for urban residents;when rhGH long-acting preparation was injected subcutaneously once a week,the combination therapy regimen was not cost-effective for residents in both rural areas and urban areas.CONCLUSIONS The combination of GnRHa and rhGH is only recommended for CPP children with better affordability to improve final height.The benefits,risks,and affordability of treatment should be comprehensively considered before the decisions on pharmacotherapy,to avoid abuse of rhGH due to the blind pursuit of height growth.

This article presents the first reported successful case of patent ductus arteriosus closure using a fully biodegradable occluder under the sole guidance of transthoracic echocardiography.Compared to traditional methods that require radiation and metal occluders,this technique,which combines echocardiography guidance with biodegradable devices,reduces iatrogenic injury and procedural risks,demonstrating favorable clinical outcomes.

Objective:To explore the optimal age cutoff for diagnosis and the prognosis of early-onset gastric cancer in young patients.Methods:Clinicopathological data of patients with gastric adenocarcinoma aged ≤45 years who had undergone radical gastrectomy in the Department of Gastric Surgery, Fudan University Shanghai Cancer Center from January 2013 to December 2018 were retrospectively collected. Patients with distant metastases, other malignant tumors, combined organ resection, gastric stump cancer, positive margin, and incomplete clinical or follow-up data were excluded. X-tile software analysis of the actual overall survival of the collected cases yielded an optimal cut-off of 32 years. Accordingly, the enrolled cases were divided into an early-onset young group (age ≤32 years) and young adult group (age >32 years). Clinicopathological characteristics, long-term survival, and postoperative recurrence were compared between the two groups. Univariate and multivariate analyses were performed using the Cox proportional hazards model to identify the factors affecting the prognosis of young patients with gastric cancer.Results:The study cohort comprised 462 patients, including 256 (55.4%) women, 419 (90.7%) with middle and lower gastric cancers, and 343 (74.2%) with poorly differentiated tumors. There were 101 patients in the early-onset young group and 361 in the young adult group. These groups did not differ significantly in terms of sex, body mass index, tumor location, tumor size, surgical procedure, neurovascular invasion, or tumor stage (all P>0.05). The proportion of patients with poorly differentiated tumors in the early-onset young group was significantly higher than that in the young adult group (89.1%[90/101] vs. 70.1%[253/361], χ 2=15.26, P<0.001). All study patients completed 5 years of follow-up, the median duration of which was 101 months (61-133 months). Death or tumor recurrence occurred in 151 patients (32.7%), in 118 of whom the sites of recurrence and metastasis could be identified, 38 in the early-onset young group and 80 in the young adult group. Fifty-five (46.6%) patients developed peritoneal metastases and 40 (33.9%) hematogenous metastases. In the early-onset young group, 20 patients developed peritoneal metastases, 11 hematogenous metastases, five distant lymph node metastases, and two local recurrence. In the young adult group, 35 patients developed peritoneal metastases, 29 hematogenous metastases, six local recurrences, and 10 distant lymph node metastases. The 5-year overall survival and disease-free survival rates were significantly higher in the young adult group than in the early-onset young group (73.7% vs. 57.4%, P=0.002 and 70.6% vs. 55.4%, P=0.004, respectively). Cox multivariate analysis showed that age >32 years (HR=0.63, 95%CI: 0.43-0.90, P=0.012) was an independent protective factor for overall survival, whereas later N stage (HR=1.67, 95%CI:1.09-2.57, P=0.018) was an independent risk factor for overall survival after surgery ( P<0.05). Age >32 years (HR=0.60, 95%CI: 0.41-0.86, P=0.006) was also an independent protective factor for disease-free survival, whereas later N stage was an independent risk factor (HR=1.69, 95%CI: 1.08-2.64, P=0.021). Conclusion:Young patients with early-onset gastric cancer aged ≤32 years have worse tumor differentiation and prognosis.

ObjectiveTo explore the effect of respiratory training based on core stabilization training on lumbar disc herniation. MethodsFrom January, 2023 to October, 2024, 96 patients with lumbar disc herniation admitted to the First Affiliated Hospital of Bengbu Medical University were divided into control group (n = 32), core group (n = 32) and respiratory group (n = 32). All the groups underwent conventional rehabilitation therapy, with core stabilization training in the core group and respiratory training combined with core stabilization training in the respiratory group, additionally, for four weeks. Before and after training, the scores of Visual Analogue Scale, Japanese Orthopaedic Association (JOA) and Oswestry Dysfunction Index (ODI) were compared, the average electromyographic value (AEMG) and root mean square (RMS) value of the multifidus and transversus abdominis were detected by surface electromyography (sEMG); and the thickness of the multifidus and transversus abdominis were measured by musculoskeletal ultrasonography bilaterally. ResultsThe intra-group effect (F > 597.796, P < 0.001), inter-group effect (F > 16.535, P < 0.001) and interaction effect (F > 49.622, P < 0.001) were significant in the scores of VAS, JOA and ODI; which were better in the respiratory group than in the control group and the core group (P < 0.05), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 7971.631, P < 0.001), inter-group effect (F > 177.760, P < 0.001) and interaction effect (F > 478.771, P < 0.001) were significant in the thickness of the transversus abdominis and multifidus; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 144303.007, P < 0.001), inter-group effect (F > 1495.458, P < 0.001) and interaction effect (F > 3121.361, P < 0.001) were significant in the RMS of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and the core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). The intra-group effect (F > 1890.532, P < 0.001), inter-group effect (F > 607.132, P < 0.001) and interaction effect (F > 824.923, P < 0.001) were significant in the AEMG of the multifidus and transversus abdominis; which were better in the respiratory group than in the control group and core group (P < 0.001), and were better in the core group than in the control group (P < 0.001). ConclusionCore training combined with respiratory training can more effectively reduce pain and improve dysfunction by enhancing the strength and control of the core muscles， thus improving the quality of life of patients with lumbar disc herniation.

Osteoarthritis(OA),a common age-related chronic disease,is characterized by degenerative changes in the joints and surrounding tissues.Traditionally,research on OA has primarily focused on the pathological changes in articular cartilage and its repair.However,with the advancements in animal disease modeling in recent years,especially the widespread use of spatiotemporally specific transgenic mouse models,scholars have gradually come to realize that the subchondral bone also plays an important role in the occurrence and development of OA.That is,the pathological changes in articular cartilage and bone mutually affect and promote each other,jointly driving the progression of OA,involving such pathological processes as vascular invasion,ectopic calcification,nerve growth,and the occurrence of pain.Given the complexity of cartilage-bone pathological relationship,it is difficult to conduct in-depth research on subchondral bone pathology using clinical human samples,or to simulate the pathological processes of OA through in vitro cell experiments.Therefore,animal models play an irreplaceable role in investigating the pathological mechanisms of OA and developing clinical drugs.This review,in addition to providing an overview of OA animal models,synthesizes the latest progress in animal experimental research on OA,highlighting the active role of the cartilage-bone pathological relationship in OA progression.These new findings provide references for future in-depth investigations and also provide a theoretical basis for developing fundamental strategies for OA prevention and treatment.

ObjectiveTo evaluate the effects of Shenling Guben Granules on quality of life and immune function in patients with HIV classified as immunological non-responders （INRs）. MethodsA prospective， multicenter， randomized， double-blind， controlled trial was conducted from August 21， 2018， to January 6， 2021， across eight hospitals in China. A total of 300 INR patients， diagnosed with spleen-kidney yang deficiency or lung-spleen Qi deficiency syndromes， were enrolled and randomly assigned to either the observation group or the control group， with 150 patients in each group. The control group received antiretroviral therapy （ART） combined with placebo， while the observation group received ART combined with Shenling Guben Granules. After 72 consecutive weeks of treatment， the World Health Organization Quality of Life for HIV brief version （WHOQOL-HIV BREF） was used to assess quality of life before and after treatment in both groups. Immune indicators （CD4⁺ and CD8⁺ T cell counts）， complete blood count， liver and renal function， and adverse events during treatment were also evaluated to assess safety. ResultsA total of 279 patients were included in the final analysis （140 in the observation group and 139 in the control group）. After treatment， CD4⁺ T cell counts in the observation group increased significantly compared to baseline （P< 0.05）， whereas the control group showed an upward trend without statistical significance. Compared with the control group after treatment， the observation group showed a significantly greater increase in CD4⁺ levels （P<0.05）. There were no significant differences in the total score or domain scores of quality of life （physical， psychological， independence， social relationships， environment， and spirituality）， or in CD8⁺ T cell counts， before and after treatment in either group. The incidence of adverse events during treatment was 10% （14/140） in the observation group and 10.07% （14/139） in the control group， with no statistically significant difference between the two groups. ConclusionAlthough Shenling Guben Granules did not significantly improve quality of life in INR patients， they significantly increased CD4⁺ cell counts and demonstrated good safety， providing scientific evidence to support their use as a treatment option for INR patients.
