Objective: To explore the relationship between visual acuity and physical fitness of university freshmen, so as to provide reference for myopia prevention and control for freshmen. Methods: From October to November 2022, 2 160 college freshman without majoring in public safety administration, selected from Guangxi Police College in 2022 by using the stratified cluster random sampling method, were reviewed for the results of visual acuity test and physical fitness scores. The physical fitness indices were evaluated by using the Z scores of physical fitness test scores, and the strength of association between the level of physical fitness index and myopia was analyzed by using Logistic regression model. Results: Among 2 160 college freshman without majoring in public safety administration, 917 (42.5%) students were diagnosed screening myopia, including 66 (3.1%) cases of high myopia, 383 (17.7%) cases of moderate myopia and 468 (21.7%) cases of mild myopia. The differences in the distribution of visual acuity tests among students with different physical fitness indices, body mass index, and gender were statistically significant ( Z/H=54.50, 49.53, 15.51, P <0.01). Low level and low middle level physical fitness indices were associated with screening myopia among freshmen[ OR (95% CI )=2.81(1.93-4.08),1.87(1.38-2.54)], and low level physical fitness indexes were associated with high myopia [ OR (95% CI )=7.22(2.33-22.32)] ( P <0.01). Conclusions Screening myopia among college freshman without majoring in public safety administration is related to physical fitness, and low level and low middle level physical fitness index are risk factors for myopia. Improving the level of physical fitness might be effective in preventing myopia.

Objective:To investigate the clinical efficacy and safety of a baby smoothing and special caring cream in reducing the recurrence of atopic dermatitis (AD) in infancy.Methods:A randomized controlled trial was conducted. Children with moderate AD (with overall investigator's global assessment [IGA] scores of 3 - < 4) were enrolled from Shunyi Maternal and Children′s Hospital of Beijing Children′s Hospital from April 2021 to June 2024. During the induction period, all children were topically treated with 0.1% hydrocortisone butyrate cream twice daily on the lesional skin, as well as with a baby smoothing and special caring cream at least twice daily throughout the body; at the 2-week visit, patients with an IGA score of ≤ 1 point entered the maintenance phase, while those with an IGA score of > 1 point continued the treatment for another 2 weeks; at the 4-week visit, patients with an IGA score of ≤ 1 point entered the maintenance phase, while those still with an IGA score of > 1 point were withdrawn from the study, and received conventional treatment. Patients who entered the maintenance period were randomly divided into the test group and the control group in a 1∶1 ratio using a random number table. In the test group, the hydrocortisone butyrate cream was discontinued, while the baby smoothing and special caring cream was continued twice daily for 8 consecutive weeks; in the control group, both the hydrocortisone butyrate cream and the baby smoothing and special caring cream were discontinued. IGA and Scoring AD (SCORAD) scores were assessed by clinicians at weeks 4 and 8 in the maintenance phase, while the patient-oriented eczema measure (POEM) score was evaluated weekly by patients' parents. The Kaplan-Meier survival analysis and Breslow test were used to compare recurrence rates in the two groups (the primary efficacy outcome), and a generalized estimating equation model was used to evaluate the changes in IGA, SCORAD, and POEM scores in the two groups (the secondary efficacy outcomes). Adverse reactions were monitored throughout the study to evaluate safety.Results:A total of 68 children with moderate AD aged from 3 months to 2 years were included. There were 38 females and 30 males, aged 11.72 ± 6.03 months. Fifty-two patients entered the maintenance phase; 2 were lost to follow-up, and 50 were included in the per-protocol set, with 28 in the test group and 22 in the control group. The recurrence rate during the maintenance phase was 7.14% (2/28) in the test group and 31.82% (7/22) in the control group, showing a significant difference between the two groups ( χ 2 = 5.08, P = 0.032). At weeks 4 and 8 in the maintenance phase, the IGA scores were significantly lower in the test group than in the control group (Wald χ 2 = 5.06, P = 0.024), whereas the SCORAD scores showed no significant differences between the two groups (Wald χ 2 = 2.92, P = 0.087). During weeks 1 - 8 in the maintenance phase, the POEM scores showed no significant differences between the two groups or over time (both P > 0.05), while the two groups showed different change trends in POEM scores over time (Wald χ 2interaction = 55.37, Pinteraction < 0.001). Throughout the entire study period, no adverse reactions were observed among all 68 subjects. Conclusion:With a high safety profile, the baby smoothing and special caring cream could reduce the recurrence rate during the maintenance phase, showing promise as an adjuvant therapy for the maintenance treatment of AD in infancy, and is worthy of clinical application.

Objective To utilize single-cell and peripheral blood transcriptomic data from 3D brain organoids,combined with machine learning,to analyze the role of mitochondrial autophagy genes in schizophrenia(SCZ).Methods By integrating two machine learning algorithms,we identified differentially expressed mitochondrial autophagy-related genes between schizophrenia patients and healthy controls using peripheral blood RNA sequencing data.The relationship between mitophagy gene,immune cells and inflammatory factors was further explored.Comprehensive single-cell analysis was used to explore the signaling pathways and specific transcription factors based on mitophagy genes.Results Using machine learning,seven key mitophagy genes expressed in schizophrenia patients were identified.Based on Mitoscore analysis,at the single-cell level,neurons with high mitochondrial autophagy activity(Mitohigh_Neuron)formed new interactions with endothelial cells via the SPP1 signaling pathway.Conclusion This study identified two subtypes of mitophagy and seven key mitophagy genes in schizophrenia,providing new insights into the pathogenesis of the disease.

Objective:To characterize the brain structure of Chinese children with autism spectrum disorder (ASD) using artificial intelligence automatic brain segmentation technique, and to analyze the correlation between the characteristics of the brain structure and the degree of brain development.Methods:A case-control study.The data of 52 children who were diagnosed with ASD according to the diagnostic criteria for ASD in the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition of the United States at the Department of Psychology of Qingdao University Affiliated Women and Children′s Hospital from January 2023 to April 2024 were prospectively analyzed.Meanwhile, 48 gender- and age-matched typically developing (TD) children in Qingdao were also included.The three-dimensional T1 weighted imaging sequences of all patients were obtained using a GE 3.0T magnetic resonance imaging scanner.Automated brain segmentation techniques were used to obtain the standardized volumes of each brain structure (the ratio of the absolute volume of the brain structure to the whole brain volume).Two-independent-samples t and Mann-Whitney U tests were used to compare the standardized volumes of different brain regions between the 2 groups.Pearson and Spearman correlation analyses were used to depict the correlations between volume data of brain areas with significant differences and Gesell Developmental Scale scores. Results:Compared with those in the TD group, the volumes of the left grey matter[25.45%(0.70%) vs.25.16%(1.05%)], the right grey matter [(25.89±0.71)% vs.(25.51±0.73)%], the right lateral orbitofrontal cortex [(0.62±0.03)% vs.(0.59±0.05)%], the right medial orbitofrontal cortex[(0.48±0.04)% vs.(0.46±0.04)%], the right pars triangularis [(0.38±0.07)% vs.(0.35±0.05)%], the left hippocampus [0.22%(0.04%) vs.0.20%(0.02%)], the right hippocampus [0.23%(0.04%) vs.0.22%(0.02%)], the left parahippocampal gyrus [0.15%(0.03%) vs.0.14%(0.02%)], the right parahippocampal gyrus [(0.15±0.02)% vs.(0.14±0.02)%], the left fusiform gyrus [(0.82±0.08)% vs.(0.78±0.08)%], the right superior temporal gyrus [(0.96±0.10)% vs.(0.90±0.09)%], the left insular lobe [(0.54±0.03)% vs.(0.53±0.04)%], the right insular lobe [(0.55±0.03)% vs.(0.53±0.04)%], the right inferior parietal cortex [(1.40±0.16)% vs.(1.33±0.12)%], the right precuneus cortex [(0.99±0.09)% vs.(0.94±0.09)%], the right putamen [(0.37±0.04)% vs.(0.35±0.03)%], the left pallidum [(0.14±0.01)% vs.(0.13±0.01)%], the right pallidum [0.14%(0.02%) vs.0.13%(0.01%)], and the right thalamus [(0.51±0.04)% vs.(0.49±0.03)%] were significantly increased in the ASD group (all P<0.05).Nonetheless, the volumes of the left pericalcarine cortex [(0.19±0.04)% vs.(0.20±0.04)%] and the corpus callosum posterior region [0.05%(0.01%) vs.0.06%(0.01%)] in the ASD group were considerably smaller than those in the TD group (all P<0.05).Correlation analysis showed that the right thalamus volume was negatively correlated with the Gesell-adaptation development quotient in children with ASD ( r=-0.276, P=0.048).The volumes of the left fusiform gyrus and left pericalcarine cortex were negatively correlated with the Gesell-fine motor development quotient in children with ASD ( r=-0.290, P=0.037; r=-0.368, P=0.007). The right precuneus cortex volume was negatively correlated with the Gesell-personal and social competence development quotient in children with ASD ( r=-0.396, P=0.007). Conclusions:Children with ASD show abnormalities in the volumes of multiple brain regions, and some brain regions are related to the degree of brain development.Automatic brain segmentation technology based on artificial intelligence can rapidly and directly measure and display the volume of brain structures in both ASD and TD children.

Objective:To explore the early predictive value of amplitude-integrated electroencephalogram(aEEG) combined with general movements（GMs）assessment for motor development outcomes in infants with severe hyperbilirubinemia at 12 months of age.Methods:The clinical data of 125 cases of neonates with severe hyperbilirubinaemia admitted to the NICU at Inner Mongolia Medical University Hospital from January 2020 to June 2022 were retrospectively analyzed.The aEEG were performed within 24 h of admission；GMs assessment were carried out at the duration of hospital stay，when the serum bilirubin values decreased below phototherapy intervention value and the infant was stable. The patients were regularly followed-up until one-year-old to evaluate the predictive values by Griffiths Developmental Scale.Results:A total of 125 infants with severe hyperbilirubinemia were enrolled，including 82（65.6%）males and 73（58.4%）females，with the mean gestational age of（38.1±1.5）weeks，the mean birth weight of（3 169±573）g，and the mean serum bilirubin of（378.5±51.9）μmol/L. Of the 125 infants diagnosed by Griffiths assessment at the age of 12 months，normal in 86 cases（68.8%），and abnormal in 39 cases（31.2%）. GMs writhing phase assessment had a sensitivity of 100%, negative predictive value of 100% and specificity of 19.77% in predicting motor developmental outcome in neonates with severe hyperbilirubinaemia. The aEEG had a sensitivity of 92.31% and a negative predictive value of 94.92% in predicting motor developmental outcome in neonates with severe hyperbilirubinaemia, with a higher specificity of 65.12%. The sensitivity and negative predictive value of aEEG+GMs assessment for predicting motor developmental outcome in neonates with severe hyperbilirubinaemia were 87.18% and 92.42%, respectively, with the highest specificity of 70.93%.Conclusion:GMs writhing stage assessment, aEEG assessment, and aEEG combined with GMs early assessment have good predictive value for motor developmental outcomes in neonates with severe hyperbilirubinaemia.The aEEG combined with GMs assessment has a high specificity, which can improve the predictive effect of motor developmental outcomes in neonates with hyperbilirubinaemia.

Objective:To describe functional disability rate of anxiety disorders in Chinese community adults and explore related risk factors of functional disability.Methods:To conduct in-depth data analysis on China Mental Health Survey(CMHS).The diagnostic tool for anxiety disorders was the Composite International Diagnostic Inter-view-3.0,according to the Diagnostic and Statistical Manual for Mental Disorders,Fourth Edition(DSM-Ⅳ).The World Health Organization Disability Assessment Schedule,2nd edition,was the functional disability assessment standard for anxiety disorders.Weighted 12-month functional disability rate of DSM-Ⅳ anxiety disorder with co-morbidities and only anxiety disorder in population and those in patients,as well as days of partial disability were calculated.The effects of anxiety disorders comorbid other mental disorders and physical diseases and demographic factors on the severity and occurrence of functional disability were analyzed by multiple linear regression and logis-tic regression.Results:The functional disability rate of anxiety disorder with comorbidities in population was 1.7％,and 42.2％in patients,in which constituent rate of grade-four disability was the highest as 84.1％.The functional disability rate of only anxiety disorder in population was 0.3％,and 17.8％in patients.The medians of days of partial disability days in the past 30 days were from 0 to 14.42.Multiple linear regression showed a positive association between comorbid anxiety disorder with other mental disorders and physical diseases(β=0.24),comor-bid other mental disorders and physical diseases(β=0.21),physical diseases(β=0.18),comorbid anxiety disor-der and physical diseases(β=0.15),comorbid anxiety disorder with other mental disorders(β=0.08),other men-tal disorders(β=0.07),only anxiety disorder(β=0.06),lower education level(β=0.12),lower economic status(β=0.08),older age(β=0.06),non-marital status(β=0.06),male(β=0.02)and the severity of functional dis-ability.Logistic regression showed that comorbid anxiety with other mental disorders and physical diseases(OR=64.07),comorbid anxiety disorders with other mental disorders(OR=36.75),comorbid other mental disorders with physical diseases(OR=20.60),comorbid anxiety with physical diseases(OR=18.88),anxiety disorder(OR=9.20),other mental disorders(OR=6.65),physical diseases(OR=4.00),65 years old and over(OR=4.40),50 to 64 years old(OR=2.33),low economic status(OR=2.10),illiterate and below primary school educational level(OR=1.89),middle economic status(OR=1.70),elementary school educational level(OR=1.59),non-marital status(OR=1.47),male(OR=1.16)were the risk factors of the occurrence of functional disability.Conclusion:Comorbidity of anxiety disorders and other mental disorders,and physical diseases increases severity and occurrence of functional disability.Comorbidity,male,gender,older age,lower economic and educa-tional level and non-marital are risk factors of anxiety disorder functional disability.

Objective:To describe disability rates of dementia in community residents aged 65 years and over in China,and explore related risk factors of disability.Methods:This study conducted an in-depth data analysis of the China Mental Health Survey.World Health Organization Disability Assessment Schedule 2.0(WHODAS 2.0)was used to assess dementia disability,Community Screening Interview for Dementia(CSID)and Geriatric Mental Status Examination(GMS)were used for dementia screening and diagnosing.Univariate analysis was used to calcu-late the weighted disability rates of dementia in population and in patients,and their population distribution.Multiple linear regression and logistic regression were used to analyze the risk factors of the occurrence of dementia disability and its severity.Results:The weighted disability rate of dementia was 2.1％in population,and 38.6％in pa-tients.The disability rates of comorbid dementia in population and in patients were higher than those of patients with only dementia.Female,older age,lower education level,lower economic status,and lower cognitive test scores in CSID had higher disability rates of dementia in population.Female and urban resident had higher disability rates of dementia in patients.Multiple linear regression showed economic status(β=0.11),gender(β=0.11),age(β=0.10),and treatment in the last 12 months(β=-0.20)were statistically associated with WHODAS 2.0 scores.Multiple logistic regression showed female(OR=2.81)and treatment in the last 12 months(OR=2.38)were statistically associated with disability.Conclusions:Persons with low economic status,female and elderly peo-ple are the high-risk groups for dementia disability.It should be paid attention to prevent dementia and its conse-quential disabilities.

The second edition of the Chinese guideline for the prevention and treatment of anxiety disorders was published in August 2023, 13 years after the first edition. The revision principles for the second edition were maintaining the first edition's framework, and based on that framework, making necessary revisions by incorporating research progress and supplementing the latest research findings from the domestic studies and the overseas literature. Referring to the DSM-5 and ICD-11 classifications of mental disorders and the actual clinical situation in China, the anxiety disorders in the second edition were panic disorder, generalized anxiety disorder, social anxiety disorder, separation anxiety disorder, and anxiety disorder due to another medical condition. The latest epidemiological data on anxiety disorders in China were added. Following the international guidelines, medications not included in the first edition have been added. Chinese traditional medicines, physical therapy, and internet web-based psychotherapy were also supplemented to fit Chinese clinical settings. Based on a literature review, the latest information on the risks of using antidepressants during pregnancy has been added.A whole course of treatment across the acute phase, consolidation phase, and maintenance phase was further addressed as the treatment principle. First-line and second-line recommendations are provided for medication selections.
