ObjectiveTo delineate imaging findings using an imaging platform and investigate the correlation between MRI characteristics of spinal cord atrophy and clinical diagnosis in children with spinal cord injury (SCI). MethodsImaging data of 150 children with SCI admitted to Beijing Bo'ai Hospital, China Rehabilitation Research Center, from January, 2002 to March, 2024 were collected and imported into the imaging platform. The anteroposterior and transverse diameters of the middle part of the spinal cord at the cross-section with the most severe atrophy were measured, and the relevant indicators of the previous normal spinal cord segment were measured as controls; the radiomic features were extracted. Clinical data of the children including gender, age, cause of injury, sensory level, motor level, spinal cord injury level, injury severity and disease course were collected. ResultsSpinal cord atrophy was identified in 81 cases (54%), among which 78 cases (96%) were American Spinal Injury Association Impairment Scale (AIS) grade A and 3 cases (4%) were AIS grade C. The upper boundary of the spinal cord atrophy site strongly correlated with the injury level, motor level and sensory level (r > 0.8, P < 0.001). ConclusionMore than half of children with SCI may develop secondary spinal cord atrophy, the vast majority of whom suffer from complete spinal cord injury; the upper boundary of spinal cord atrophy is correlated with the injury level.

ObjectiveTo construct an actor-network for integrating physical activity into rehabilitation services based on the World Health Organization Rehabilitation in Health Service System framework and actor-network theory (ANT). MethodsContent analysis was employed using the six building blocks of health service systems as the theoretical framework. Actors related to rehabilitation services were extracted and categorized into a rehabilitation actor pool, while a physical activity actor pool was formed based on four major physical activity scenarios. Actors from both pools were integrated, deduplicated and classified to form a final list of integrated actors. Using ANT, the construction process of the actor network integrating physical activity into rehabilitation was analyzed through the four stages of translation: problematization, interessment, enrollment and mobilization. ResultsA dynamic integration network was constructed, comprising human actors (patients, rehabilitation professionals, researchers, sports coaches, government departments, medical institutions, community organizations and industry media, etc.) and non-human actors (assistive devices, sports infrastructure, smart equipment, information systems, online exercise guidance systems, laws and regulations, strategic documents, and exercise prescriptions, etc.). The study identified maximizing rehabilitation outcomes as the mandatory passage point and elaborated on the critical role of government departments as focal actors in coordinating various stakeholders. ConclusionThe integration of physical activity into rehabilitation services is a dynamic network constructed by diverse actors through a process of translation. ANT provides an operational theoretical framework for cross-departmental governance of rehabilitation policies in China, promotes the spatial expansion of the rehabilitation field, and drives its transformation toward a networked and ecological system. The government needs to play a leading role in facilitating role reconstruction and synergy among heterogeneous actors in both the sports and rehabilitation sectors through mechanism design, to create a bidirectional empowerment mechanism that fosters mutual progress and ensures the sustainable development of integrated services.

Objective:To develop a deep learning-based segmentation model MT-UNet to automatically segment bone metastases and benign bone lesions in bone scintigraphy with SPECT/CT.Methods:A total of 93 patients (48 males and 45 females, age 28-84 years) who underwent bone SPECT/CT in the Department of Nuclear Medicine, General Hospital of Northern Theater Command from June 2023 to December 2023 were enrolled retrospectively in this study, with a total of 184 bone lesions (94 benign lesions and 90 metastatic tumors). The MT-UNet was employed to segment bone lesions in SPECT, CT and SPECT/CT images respectively. Comparative analysis with 8 segmentation models was performed. The training set and validation set were divided by using 5-fold cross-validation and transfer learning was introduced to further enhance the robustness of the model. An additional cohort of 22 patients (15 males and 7 females, age 37-87 years) who received bone SPECT/CT in the Department of Nuclear Medicine, General Hospital of Northern Theater Command from April 2023 to May 2023 were included, comprising 40 bone lesions (22 benign lesions and 18 metastatic tumors) as the test set of MT-UNet. Segmentation performance of different models was assessed using accuracy, sensitivity, specificity, AUC, intersection over union and Dice similarity coefficient (DSC). Delong test was used to compare the segmentation efficacy among different models in the test set.Results:In the validation set, MT-UNet demonstrated DSC of 0.940, 0.962, and 0.963 for SPECT, CT, and SPECT/CT bone lesion segmentation, respectively, which were outperformed other models. Following transfer learning implementation, the SPECT/CT model′s DSC was improved to 0.984. In the test set, MT-UNet maintained comparable segmentation performance to the validation set, with significant AUC differences among the three models ( Z values: from -15.42 to -9.27, all P<0.01). Compared with conventional image interpretation, MT-UNet-based segmentation reduced physician interpretation time from 164min to 102min. Conclusion:MT-UNet has shown good performance in automatic segmentation of bone metastases and benign bone lesions, and is expected to become an important part of SPECT/CT image intelligent diagnosis system for bone metastases.

Objective:To explore the mechanism for the occurrence and phenotypic characteristics of Turner syndrome based on a prenatally diagnosed case of a mosaic karyotype containing double pseudo-isodicentric X chromosome and a review of relevant literature.Methods:A fetus who was diagnosed with increased risk of trisomy 21 at the Provincial Hospital Affiliated to Shandong First Medical University in August 2023 was selected as the study subject. Clinical data of the fetus was collected. Following amniocentesis, chromosomal G-banding karyotype analysis and chromosomal microarray analysis (CMA) were carried out. This study has been approved by the Ethics Committee of the Hospital (Ethics No.: SWYX No. 2022-287).Results:The early-trimester screening suggested a high risk of trisomy 21(1/19), with free β-hCG of 116 ng/mL (MoM value 2.35), PAPP-A of 0.394 ng/mL (MoM value 0.12), and NT value of 1.3 mm, though no abnormality was found in the fetus at 19 weeks gestation. The karyotype of amniocyte was determined as 46, X, psu idic(X)(p11.21)[55]/45, X[27]/47, X, psu idic(X)(p11.21)×2[5]/46, XX[13]. CMA has yielded a result of arr[GRCh37] Xp22.33p11.21(168552_55585678)×1[0.67], Xp11.21q28(55703291_155233098)×3[0.5].Conclusion:Karyotypes of Turner syndrome are complex and diverse, and a rare 46, X, psu idic(X)(p11.21)[55]/45, X[27]/47, X, psu idic(X)(p11.21)×2[5]/46, XX[13] mosaic karyotype with double pseudo-isodicentric X chromosome has been identified. Literature review suggested that this karyotype may lead to phenotypic diversification and a risk of reduced sensitivity to hormone therapy.

Objective:To understand the current status of epidemiological investigation task force construction and the performance of infectious disease epidemic response in county (district) Centers for Disease Control and Prevention (CDCs) in China, analyze the influencing factors and provide scientific evidence to improve the construction of grassroot epidemiological investigation task force.Methods:A survey was conducted in epidemiological investigation staff in county (district) CDCs in 31 provinces (autonomous regions/municipalities) and Xinjiang Production and Construction Corps in China. A self-designed questionnaire was used to collect information based on the epidemiological dynamic data collection platform of China CDC. A descriptive epidemiological analysis was conducted, and multiple linear regression models were used to identify the factors associated with the performance of infectious disease epidemic response.Results:A total of 24 934 epidemiological investigation task force members from 2 897 county (district) CDCs were surveyed in the study. In the epidemiological investigation task force, women, those with bachelor's degree and public health workers accounted for 62.46%, 71.36%, and 49.05% respectively. Up to 91.72% of the task force members had participated in field epidemic response. The average score of awareness of epidemic investigation procedures was 60.00, while the average score of key skill proficiency in the investigation was 42.22. The epidemic response performance showed correlations with area, gender, age, education level, major, and field epidemiology training programs, those who had received longer training showed higher competency scores (all P<0.001). Conclusions:Progress has been made in the construction of epidemiological investigation task force in grass-root CDCs in China, but further improvements are needed, especially in the knowledge awareness and investigation skills of the task force. Field epidemiology training demonstrated substantial impact on the improvement of epidemic response performance, indicating that it is necessary to further strengthen the training in grassroot public health workers for the better response to infectious disease epidemics.

Objective:To understand the awareness of influenza and influenza vaccine, influenza incidence, influenza vaccination status and intention and related factors in primary and secondary school teachers.Methods:Cross-sectional study design and stratified random sampling method were used to select 5 teachers from each of 51 primary schools and 40 middle schools in a district of Beijing from April 17 to 21, 2024. A questionnaire survey was conducted in the selected teachers with an estimated sample size of 1 040. The survey collected the information about their demographic characteristics, awareness of influenza and influenza vaccine, influenza incidence, influenza vaccination status and intention. Multivariate logistic regression model was used to analyze the factors related to influenza vaccination status and intention.Results:In the 975 primary and secondary school teachers, the awareness of susceptibility and severity of influenza and the benefits of influenza vaccination were high. In terms of safety of influenza vaccine, 48.00% (468/975) of the teachers believed that adverse reaction would occur after the vaccination. Influenza like illness occurred in 41.13% (401/975) of the teachers during 2023-2024, and in these teachers, 40.15% (161/401) asked for leave from work due to illness, 40.90% (164/401) sought medical care and 32.93% (54/164) were influenza virus positive. In the 975 teachers, 13.95% (136/975) were vaccinated against influenza during 2023-2024 and 34.46% (336/975) were willing to be vaccinated against influenza during 2024-2025. Multivariate logistic regression analysis showed that being teacher in charge of a class (a OR=1.58, 95% CI: 1.06-2.35), believing that influenza vaccination could effectively prevent influenza (a OR=1.99, 95% CI: 1.05-3.80), believing that teachers' vaccination could improve students' willingness to be vaccinated (a OR=1.98, 95% CI: 1.12-3.50) were the positive factors for teachers' vaccination, and worrying about adverse reactions after the vaccination (a OR=0.52, 95% CI: 0.34-0.80) was the negative factor. Doctors' recommendation (a OR=2.62, 95% CI: 1.41-4.86) and free influenza vaccination (a OR=10.26, 95% CI: 5.17-20.39) were positively correlated with teachers' intention to influenza vaccination. Conclusions:Primary and secondary school teachers in a district of Beijing had high awareness of influenza and influenza vaccine, but their awareness of influenza vaccine safety should be improved. The incidence of influenza-related infection was high in the primary and secondary school teachers. The influenza vaccination rate was low and the willingness to receive influenza vaccination in following year was not strong. For the better prevention and control of influenza in schools, it is necessary to strengthen the health education in primary and secondary school teachers to improve their awareness of influenza vaccine safety and vaccination rate.

Objective:To evaluate the long-term clinical efficacy and the influence on anal function of surgery combined with ustekinumab (UST) in active Crohn's disease (CD) patients with perianal fistula.Methods:A retrospective cohort study was conducted. Clinical data of active CD patients with perianal fistula undergoing surgery combined with UST at Longhua Hospital of Shanghai University of Traditional Chinese Medicine from August 2020 to December 2022 were collected. The primary endpoints were clinical healing rate, Wexner score, and anorectal manometry values at week 52 of treatment. Secondary endpoints included the Crohn's disease activity index (CDAI), perianal Crohn's disease activity index (PDAI), laboratory indicators [C-reactive protein (CRP), erythrocyte sedimentation rate (ESR), fecal calprotectin (FC) ], endoscopic remission rate, Van Assche score, and radiographic healing rate at week 52 of treatment.Results:A total of 28 patients were included, with 22 males (78.6%) and 6 females (21.4%) ; age (25.2 ± 7.7) (16.0-52.0) years. There was 1 patient (3.6%) of simple anal fistula. There were 27 patients (96.4%) of complex anal fistulas, including 12 of high intersphincteric type, 15 of high transsphincteric type, in which 15 with branched tracts (or ≥2 fistula tracts). The pre-treatment CDAI was 187.0 (156.0, 245.0), and the PDAI was 10.0 (9.0, 12.0). Among the 28 patients, 23 (82.1%) underwent fistulotomy, 1 (3.6%) underwent transanal opening of intersphincteric space (TROPIS), and 4 (14.3%) underwent video-assisted anal fistula treatment (VAAFT) combined with fistula-tract laser closure (FiLaC). All the patients received UST treatment postoperatively, without concurrent use of immunosuppressants or corticosteroid therapy. At week 52 of treatment, 28 (100%) patients achieved clinical healing. Compared to pre-treatment, Wexner score of patients at week 52 of treatment was significantly lower [0 (0, 0) vs. 1.0 (0, 3.0), P < 0.001], maximum anal sphincter pressure increased [ (137.6±40.9) mmHg vs. (105.1±29.2) mmHg, P < 0.001], maximum anal sphincter contraction time extended [9.0 (5.0, 15.0) s vs. 4.0 (2.0, 6.0) s, P < 0.001], and there was no significant decrease in anal resting pressure ( P > 0.05). Compared to pre-treatment, CDAI, PDAI, Van Assche scores, and simple endoscopic score for Crohn's disease (SES-CD) of patients at week 52 of treatment all significantly decreased (all P < 0.001), and CRP, ESR, and FC all decreased (all P < 0.05), with statistically significant differences. The radiographic healing rate at week 52 of treatment was 75.0% (21/28), and the radiographic remission rate was 92.9% (26/28). The endoscopic remission rate was 57.1% (16/28), and the endoscopic response rate was 82.1% (23/28) . Conclusion:The long-term clinical healing rate of active CD patients with perianal fistula receiving surgery combined with UST is high, and the anal function can be improved significantly.

This article introduces Professor Zhou Peng's clinical experience in treating generalized anxiety disorder(GAD)using spirit-regulating and root-strengthening integrated acupuncture.Based on the pathological characteristics of GAD,Professor Zhou Peng summarizes its pathogenesis as"disharmony of qi,blood,yin,and yang,"pointing out that"deficiency"is the essence of its onset,with spleen and kidney deficiency being the root cause.He advocates treating GAD from the perspective of"deficiency and decline,"focusing on strengthening the spleen and kidneys,consolidating the root,and nourishing the source,while also regulating the mind.The integrated acupuncture therapy includes needling,refined moxibustion,and intradermal needle embedding.Needling is used to harmonize qi and blood,refined moxibustion to regulate and supplement yin and yang to consolidate the root,and intradermal needle embedding to regulate the mind and consolidate the therapeutic effects of acupuncture.Starting from improving patients'compliance with treatment and ensuring sustained therapeutic effects,Professor Zhou emphasizes that acupuncture manipulation should be fast,gentle,and soft,with needle insertion resembling a swift crane touching the waves and needle manipulation like a deer drinking from a clear spring.He places great importance on patients'sensations and aims to holistically regulate the body's qi,blood,yin,and yang,restoring the balance of body and mind,thereby effectively treating generalized anxiety disorder.

Objective To investigate the effects of modified Banxia Baizhu Tianma Decoction(BBTD)on blood pressure and lipid metabolism in patients with metabolic hypertension and dyslipidemia of phlegm-damp obstruction syndrome,guided by Professor Tong Xiaolin's"state-target differentiation and treatment"theory.Methods Sixty eligible patients treated at Chongqing Beibei Hospital of Traditional Chinese Medicine from February 2024 to February 2025 were randomly assigned to treatment group(n=30,receiving conventional therapy plus modified BBTD)and control group(n=30,conventional therapy alone)for 4 weeks.The changes in blood pressure,lipid profiles,body mass index(BMI),fasting blood glucose(FBG),serum uric acid(SUA)were observed,and the antihypertensive efficacy and traditional Chinese medicine(TCM)syndrome efficacy were evaluated.Results(1)Regarding participant dropout,during the study,2 cases in the treatment group were lost to follow-up,while no dropouts occurred in the control group.Ultimately,58 patients were included in the efficacy analysis(28 in the treatment group,30 in the control group).(2)In terms of antihypertensive efficacy,after 4 weeks of treatment,the total effective rate was 92.86％(26/28)in the treatment group versus 36.67％(11/30)in the control group.The intergroup comparison(by chi-square test)demonstrated significantly superior antihypertensive efficacy in the treatment group(P＜0.05).(3)For TCM syndrome efficacy,the marked improvement rate and total effective rate in the treatment group were 60.71％(17/28)and 92.86％(26/28)respectively,compared to 0.00％(0/30)and 33.33％(10/30)in the control group.The treatment group showed significantly better outcomes in marked improvement rate(by chi-square test),total effective rate(by chi-square test),and overall efficacy(by rank-sum test)(all P＜0.05).(4)Regarding blood pressure,post-treatment systolic blood pressure(SBP)and diastolic blood pressure(DBP)were significantly decreased in the treatment group(P＜0.05)but remained unchanged in the control group(P＞0.05).The treatment group exhibited significantly greater reductions in both SBP and DBP compared to controls(P＜0.05).(5)For lipid profiles,the treatment group showed significant post-treatment reductions in total cholesterol(TC),triglycerides(TG),and low-density lipoprotein cholesterol(LDL-C)(P＜0.05).The control group demonstrated increased TG(P＜0.05),with nonsignificant decreases in TC and LDL-C,and a slight increase of HDL-C(P＞0.05).The treatment group achieved significantly greater TC and TG reductions versus controls(P＜0.05).(6)The treatment group showed decreased BMI,fasting glucose,and serum uric acid(P＜0.05),whereas the control group had unchanged BMI and fasting glucose(P＞0.05)but increased uric acid(P＜0.05).The treatment group's reductions in fasting glucose and uric acid were significantly superior to those of control group(P＜0.05).Conclusion State-target-guided modified BBTD effectively treats metabolic hypertension with dyslipidemia of phlegm-damp obstruction syndrome,demonstrating comprehensive metabolic benefits beyond blood pressure control.

Objective To analyze the correlation between serum oxidative stress indicators and cog-nitive dysfunction in patients with sleep disorders accompanied by anxiety and depression.Methods A total of 196 patients with sleep disorders accompanied by anxiety and depression in the hospital from A-pril 2021 to April 2023 were selected as research objects,and serum malondialdehyde(MDA),total superoxide dismutase(T-SOD),interleukin-6(IL-6)and γ-glutamyltransferase(γ-GGT)levels were measured in all the patients.Montreal Cognitive Assessment Scale(MoCA)was used to evaluate pa-tients'cognitive function,and based on MoCA score,they were divided into cognitive dysfunction group(n=80)and non-cognitive dysfunction group(n=116).Pearson correlation analysis was used to explore the correlations of serum MDA,T-SOD,IL-6 and γ-GGT levels with Pittsburgh Sleep Quali-ty Index(PSQI)score.Spearman rank correlation analysis was used to explore the correlations of ser-um MDA,T-SOD,IL-6 and γ-GGT levels with cognitive dysfunction in patients with sleep disorders accompanied by anxiety and depression.Receiver operating characteristic(ROC)curve was used to evaluate the values of serum MDA,T-SOD,IL-6 and γ-GGT in assessing cognitive dysfunction in patients with sleep disorders accompanied by anxiety and depression.Results Serum MDA,IL-6 and γ-GGT levels as well as PSQI score were significantly higher in the cognitive dysfunction group than those in the non-cognitive dysfunction group,while the T-SOD level was significantly lower in the cognitive dysfunction group(P＜0.05).Pearson correlation analysis results showed that serum MDA,IL-6 and γ-GGT levels were positively correlated with PSQI score(r=0.128,r=0.317,r=0.261,P=0.037,P＜0.001,P＜0.001,respectively),while serum T-SOD level was nega-tively correlated with PSQI score(r=-0.145,P=0.021).Spearman rank correlation analysis re-sults showed that serum MDA,IL-6 and γ-GGT levels were positively correlated with the occurrence of cognitive dysfunction(r=0.322,0.554,0.441,P＜0.001),while serum T-SOD level was negatively correlated with the occurrence of cognitive dysfunction(r=-0.330,P＜0.001).ROC curve analysis results showed that the areas under the curve(AUCs)for the individual and com-bined assessment of serum MDA,T-SOD,IL-6 and γ-GGT in patients with sleep disorders accompa-nied by anxiety and depression for cognitive dysfunction were 0.689,0.694,0.825,0.759 and 0.955 respectively,with cut-off values of 9.6 mmol/L,71.6 U/L,5.2 μg/L and 48.8 U/L,sen-sitivities of 50.00％,77.50％,71.25％,73.75％and 91.25％respectively,and specificities of 84.48％,62.93％,81.90％,70.69％and 88.79％respectively.Conclusion Cognitive dys-function in patients with sleep disorders accompanied by anxiety and depression is closely related to serum MDA,T-SOD,IL-6 and γ-GGT,and early measurement of these indicators can provide a ref-erence for the clinical assessment of cognitive dysfunction.
