OBJECTIVE To evaluate the quality of diagnosis and treatment guidelines and expert consensuses on childhood immune thrombocytopenic purpura （ITP） published domestically and internationally， in order to provide reference for clinical practice and future guideline/expert consensus development and improvement. METHODS A systematic search was conducted across multiple databases， including PubMed， Cochrane Library， Embase， CNKI， Wanfang data， VIP， CBM； additionally， supplementary searches were carried out on websites such as Medlive， the Chinese Medical Association’s official website， and National Institute for Health and Clinical Excellence in the UK. The retrieval time ranged from the inception to September 2， 2024. Researchers who had undergone systematic training independently evaluated the methodology and report quality included in the guideline/consensus using the Appraisal of Guidelines Research and Evaluation Ⅱ （AGREE Ⅱ） and the Reporting Items for Practice Guidelines in Healthcare （RIGHT）. RESULTS A total of 11 guidelines/consensuses were included. The average scores for the six domains of AGREE Ⅱ tool respectively were “range and purpose” （[ 66.67±17.98）% ]， “participants” [58.33% （13.89%，73.61%）]， “rigor” （[ 41.81±23.85）% ]， “clarity”（[ 69.57±19.35）%]， “applicability” （[ 35.98±17.83）%]， and “independence” [27.08% （0，75.00%）]； out of 11 articles， 9 had a recommendation level of B， 2 had a recommendation level of C， and there were no A-level articles. The average reporting rates of the 7 areas in the RIGHT tool were “basic information” （[ 72.35±12.95）% ]， “background” （[ 54.55±15.40）%]，“ evidence” （[ 36.36±24.81）%]，“ recommended opinions” （[ 53.25±19.20）%]，“ review and quality assurance” [0 （0， 25.00%）]， “funding and conflict of interest statement and management” [12.50%（0，25.00%）]， and other aspects [8.33%（0， 50.00%）]. In addition， there was no statistically significant difference in the AGREE Ⅱ and RIGHT scores between the guidelines and consensuses （P＞0.05）. CONCLUSIONS The overall quality of the guidelines and consensuses included in this study is not high， with a recommended level of B or C. It is recommended that clinical decision-making prioritize referring to the relatively high-quality guideline/consensus among them. The quality of evidence in the existing traditional Chinese medicine guidelines for children with ITP needs to be improved， and there is no integrated guideline/consensus for traditional Chinese and Western medicine. It is recommended to revise or write relevant guideline/consensus according to the requirements of AGREE Ⅱ and RIGHT in various fields to guide clinical practice.

Objective: To study the association between 24 h activities and Fundamental Motor Skills (FMS) among children with autism spectrum disorder (ASD) using compositional data analysis, and the expected changes in FMS after isochronous substitution of each activity, in order to provide reference basis for improving FMS levels in children with ASD. Methods: From October 2023 to April 2024, a total of 301 children with ASD aged 6-10 from 7 special education schools in Jinan, were investigated by cluster random sampling, and 24 h movement behaviors were calculated based on accelerator data. Test of Gross Motor Development- 2 was used to assess FMS. R software was used to perform the descriptive statistical, multiple linear regression and isochronous substitution analyses. Results: The proportion of moderatevigorous physical activity (MVPA) in children with ASD was positively related with FMS scores, locomotor, and object control skills ( β=12.42, 6.32, 6.10, P <0.01). Reallocating 15 min from sleep (SLP) to MVPA resulted in respective increases of 3.66, 1.91, and 1.75 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from sedentary behavior (SB) to MVPA resulted in respective increases of 3.72, 1.88 , and 1.83 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Reallocating 15 min from light physical activity (LPA) to MVPA resulted in respective increases of 3.32, 1.57, and 1.74 points in FMS scores, locomotor skills, and object control skills ( P <0.05). Moreover, reallocating 15 min from SB to LPA resulted in an increase of 0.28 points in locomotor skills ( P <0.05). Dose response analysis revealed that substitution of MVPA for SLP, SB, and LPA in children with ASD enhanced their FMS levels, and their substitution was asymmetrical; and substitution of LPA for SB enhanced locomotor skills level. Conclusions Among the 24 h movement behaviors, increasing the time spent on MVPA and LPA have positive impacts on the FMS of children with ASD. Schools and families should optimize the allocation of 24 h activity time in children with ASD, so as to promote the improvement of FMS levels of children with ASD.

This study performed to determine whether OX40L overexpressed by recombinant rabies virus(LBNSE-OX40L)can enhance the innate immune response through activation of dendritic cells and thus activate early antibody production.Bone marrow dendritic cells(BMDCs)were extracted from the femur of Balb/c mice and cultured for 6 days,and the cultured BMDCs were infected with the parental virus LBNSE and the recombinant virus LBNSE-OX40L with the multiplicity of infections(MOI)=1.The effect of each virus on the maturation of BMDCs was analyzed by flow cytometry;ELISA was used to detect the expression of innate immunity-related cytokines such as interferon-α(IFN-α)and interleukin-12p40(IL-12p40)in the supernatants of the infected BMDCs.For in vivo study,Balb/c female mice were injected intramuscularly with 106 FFU of parental virus LBNSE and recombinant virus LBNSE-OX40L in both hind limbs,and the inguinal lymph nodes of mice were collected on day 6 after immunization,and the proportion of mature DCs was detected by flow cytometry.The serum was collected on day 6 after immunization,and the content of virus-neutralizing antibody(VNA)was detected by antiviral neutralizing antibody titration.Mouse serum was collected on day 6 after immunization,and virus neutralizing antibody content was measured by titration of antiviral neutralizing antibody,while IgG antibody in mouse serum was detected by ELISA.IgM antibody subclasses were detected by ELISA on days 2,4,and 6 after immunization.Compared with the parental virus LBNSE,the recombinant virus LBNSE-OX40L was able to activate more BMDCs in vitro and produce significantly higher levels of IFN-α and IL-12p40.Furthermore,the recombinant virus LBNSE-OX40L stimulated the maturation and differentiation of the DCs in vivo,which led to the rapid production of high levels of VNA and RABV-specific IgG and IgM antibodies.Taken together,LBNSE-OX40L activates dendritic cells to promote the body's innate immune response,and in turn enhances early antibody production,thus can be an early effective rabies vaccine candidate.

Objective:To understand the current rehabilitation status and existing problems of patients with degenerative scoliosis after surgery, and analyze the needs of continuous health education for patients.Methods:A total of 15 patients with degenerative scoliosis undergoing surgical treatment in Nanjing Drum Tower Hospital, Affiliated Hospital of Medical School, Nanjing University from December 2021 to June 2022 were selected by the convenient sampling method. The semi-structured interview was used to understand the patient's feelings on the operation effect, experience on the postoperative life impact, thoughts on rehabilitation exercise, self-cognition of home status and future development planning. Based on the rooted theory, Colaizzi 7-step analysis was applied to extract the topic.Results:The four themes related to the continuous health education needs of patients with degenerative scoliosis after surgery were summarized, which were unacceptable movement limitation of lower back or lower extremity, blind area of continuous rehabilitation exercise, lack of knowledge of self-management of spinal disease after surgery and need for social and psychological support.Conclusions:Patients with degenerative scoliosis lack of postoperative rehabilitation knowledge and skills, and the need for health education is strong. Medical staff can meet the patients' transitional care needs by educating them to adapt to the current situation, providing personalized rehabilitation goals, guiding patients in managing risk factors that affect their own rehabilitation and improving social and family support systems, thereby promoting rapid recovery of patients.

【Objective】 To explore the correlation between the severity of jaundice in ABO hemolytic disease of fetus and newborn (HDFN) and multiple indicators, in order to achieve accurate diagnosis, timely treatment, and prevent complications in ABO HDFN. 【Methods】 From March 2020 to February 2023, a total of 283 ABO HDFN in our hospital were classified into mild, moderate and severe groups based on total bilirubin levels. The differences in basic data, relevant laboratory indicators and the agglutination intensity of the three hemolysis tests were analyzed and compared. 【Results】 In the severe group, 75% (12/16) were male infants, which was significantly higher compared to 37.5% (57/152) in the moderate group (P<0.05). The values (mg/dL) of transcutaneous jaundice in the mild, moderate and severe groups were:forehead 9.88±1.93 vs 12.34±2.01 vs 15.56±2.69, face 10.25±2.27 vs 13.28±2.32 vs 15.99±2.86, chest 9.67±2.16 vs 12.51±2.11 vs 15.33±2.36, respectively. The values(µmol/L) of direct bilirubin (DBIL) and indirect bilirubin (IBIL) were 9.87±2.06 vs 11.90±2.59 vs 16.12±4.73, and 159.36±37.55 vs 252.98±30.52 vs 353.76±55.68, respectively, and the differences between the mild, moderate and severe groups were statistically significant (all P<0.05) . The creatine kinase (CK) values(unit/L) of mild, moderate and severe groups were 664.15±498.26 vs 500.51 ±451.63 vs 402.63±224.27, and the difference between the mild group and the other two groups was statistically significant (P<0.05) . There was no statistically significant difference in the agglutination intensity of the three hemolysis tests among HDFN with different severity of jaundice. 【Conclusion】 Clinicians can predict the severity of jaundice in light of gender, transcutaneous jaundice, DBIL, IBIL and CK of ABO HDFN, for further and graded treatment, so as to avoid the sequelae or even life-threatening consequences caused by ABO HDFN.

Objective:To develop and examine the reliability and validity of the adolescent health literacy evaluation scale under public health emergencies (AHLES-PHE) in junior middle school students.Methods:The initial version of AHLES-PHE was formed by combining the characteristics of public health emergencies and adolescent health literacy.The expert version of AHLES-PHE was formed by two rounds of Delphi expert consultation.Totally 1 729 adolescent students from three junior middle schools in Changzhou City were tested.The formal version of AHLES-PHE was formed through item analysis and factor analysis (structural validity). The content validity of the formal version of AHLES-PHE was evaluated by specialist analysis and sensibility analysis, and its correlation validity with the everyday health information literacy (EHIL) was tested.The internal consistency reliability, parity split-half coefficient and test-retest reliability were calculated.Results:(1)Item analysis: the correlation coefficient between the scores of each item and the total score of AHLES-PHE expert version was 0.420 to 0.722 ( P<0.01), and the CR of decision value was 10.140 to 66.980 ( P<0.01). (2)Validity analysis: the formal version of AHLES-PHE with 45 items and 8 factors was obtained by exploratory factor analysis.The 8 factors could explain 61.30% of the total variation.The fitting indexes of the confirmatory factor analysis model were χ2/ df=3.325, RMSEA=0.052, GFI=0.853, CFI=0.912, TLI=0.904, NFI=0.880.Sensibility analysis of the formal version of AHLES-PHE showed the Cronbach's α ranged from 0.957 to 0.958.The correlation coefficient between the total score of AHLES-PHE formal version and the total score of EHIL was 0.340 ( P<0.01). (3)Reliability analysis: the Cronbach's α coefficient and parity split-half coefficient of the formal version of AHLES-PHE were 0.958 and 0.975, respectively.The test-retest reliability of the formal version of AHLES-PHE was 0.753 ( P<0.01). Conclusion:The formal version of AHLES-PHE developed in this study has good reliability, structural validity and content validity, and the correlation validity with EHIL is common.This scale has a certain degree of applicability to the assessment of health literacy for junior middle school students under public health emergencies.

Objective:To explore the related risk factors for systemic embolism (SE) in patients aged≥75 years with non-valvular atrial fibrillation (NVAF).Methods:A case-control study. NVAF patients aged≥75 years who were hospitalized at the First Affiliated Hospital of Xinjiang Medical University from October 2018 to October 2020 were divided into no SE ( n=1 127) and SE ( n=433) groups according to the occurrence of SE after NVAF. Multivariate logistic regression was used to analyze SE-related factors in patients with NVAF without anticoagulation treatment. Results:In the multivariate model, the following factors were associated with an increased risk of SE in patients with NVAF: history of AF≥5 years [odds ratio ( OR)=2.75, 95% confidence interval ( CI) 1.98-3.82, P<0.01], lipoprotein(a)>300 g/L ( OR=2.07, 95% CI 1.50-2.84, P<0.01), apolipoprotein (Apo)B>1.2 g/L ( OR=1.91, 95% CI 1.25-2.93, P=0.003), left ventricular ejection fraction (LVEF) of 30%-49% ( OR=2.45, 95% CI 1.63-3.69, P<0.01), left atrial diameter>40 mm ( OR=1.54, 95% CI 1.16-2.07, P=0.003), and CHA 2DS 2-VASc score≥3 ( OR=15.14, 95% CI 2.05-112.13, P=0.01). ApoAI>1.6 g/L was negatively correlated with the occurrence of SE ( OR=0.28, 95% CI 0.15-0.51, P<0.01). Conclusions:History of AF≥5 years, lipoprotein(a)>300 g/L, elevated ApoB, left atrial diameter>40 mm, LVEF of 30%-49%, and CHA 2DS 2-VASC score≥3 are independent risk factors for SE whereas ApoAI>1.6 g/L is a protective factor against SE in patients with NVAF.

Objective:To carry out a scoping review on feeding decision aids in patients with advanced dementia, clarify the characteristics, functions, and application effects of the tools, so as to provide reference for further clinical research.Methods:The research on feeding decision aids for patients with advanced dementia was systematically searched on China National Knowledge Infrastructure (CNKI) , VIP, WanFang Data, and the China Biomedical Literature Library, PubMed, Web of Science, Embase, and Cochrane Library. The search period was from database establishment to August 2022. Two researchers independently selected literature based on inclusion and exclusion criteria, extracted, summarized and analyzed data from the included literature.Results:A total of 8 decision aids were included. The main types included web-based decision aids, paper text decision support manuals, audio manual form decision aids, and a combination of various forms of decision aids. Decision aids provided dementia feeding related information to patients and surrogate decision-makers, analyzed the advantages and disadvantages of different feeding methods, helped clarify their value preferences, and assisted them in making feeding decisions. The evaluation of application effectiveness mainly included outcome indicators such as knowledge, decision conflict, decision regret, decision satisfaction, frequency of doctor-patient communication, and acceptability and effectiveness of decision aids.Conclusions:Decision aids have played a positive role in selecting feeding methods for dementia patients and surrogate decision-makers. Under the background of "Internet + nursing service", we can learn from the experience of foreign research and make full use of artificial intelligence technology to explore scientific and feasible personalized decision aids, so as to provide demand based decision support for patients and their surrogate decision-makers and improve the quality of decisions.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.

Aristolochic acids (AAs) have long been considered as a potent carcinogen due to its nephrotoxicity. Aristolochic acid I (AAI) reacts with DNA to form covalent aristolactam (AL)-DNA adducts, leading to subsequent A to T transversion mutation, commonly referred as AA mutational signature. Previous research inferred that AAs were widely implicated in liver cancer throughout Asia. In this study, we explored whether AAs exposure was the main cause of liver cancer in the context of HBV infection in mainland China. Totally 1256 liver cancer samples were randomly retrieved from 3 medical centers and a refined bioanalytical method was used to detect AAI-DNA adducts. 5.10% of these samples could be identified as AAI positive exposure. Whole genome sequencing suggested 8.41% of 107 liver cancer patients exhibited the dominant AA mutational signature, indicating a relatively low overall AAI exposure rate. In animal models, long-term administration of AAI barely increased liver tumorigenesis in adult mice, opposite from its tumor-inducing role when subjected to infant mice. Furthermore, AAI induced dose-dependent accumulation of AA-DNA adduct in target organs in adult mice, with the most detected in kidney instead of liver. Taken together, our data indicate that AA exposure was not the major threat of liver cancer in adulthood.
