ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome）. MethodsThrough a multi-center randomized controlled methodology design，confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals，such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days，and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale （CARIFS） and the incidence of complications，severe cases， and critical cases. Follow-up observation was conducted on the day of enrollment，48 hours after medication，72 hours after medication， and （6+1） d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group （90 cases） or the control group （90 cases）. All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was （5.29±1.25） d，and that in the control group was （5.40±1.68） d，without a statistically significant difference. After five days of intervention，52 cases in the experimental group and 51 cases in the control group converted to negative，without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention，there were statistically significant differences between the experimental group and the control group in three dimensions， including headache，muscle soreness， and the need for extra care （P<0.05）. On the （6+1） days after the intervention，the differences in both the experimental group and the control group were statistically significant in 10 dimensions， including sore throat，bad sleep，uncomfortable feeling，poor spirit and fatigue，crying more than usual，the need for extra care，symptom，function，influence on parents，and total score （P<0.05）. The comparison results within the group in the dimensional scores of symptom， function， and influence on parents，as well as the CARIFS total score showed that with the delay of follow-up time，scores of both groups decreased significantly，with a statistically significant difference （P<0.01）. Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention，the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up，the mean score of the experimental group was lower than that of the control group，with no statistically significant difference. In terms of the incidence of complications，severe cases， and critical cases， there were no complications，severe cases， and critical cases in the two groups，without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children （heat accumulation in the lung and stomach syndrome） are not inferior to Oseltamivir Phosphate granules， and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children （heat accumulation in the lung and stomach syndrome）.

OBJECTIVE: To investigate the current status of clinical genetics specialization development and the diagnostic and therapeutic capabilities for hereditary diseases across medical institutions in Shanghai, and to assess the necessity and feasibility of establishing training bases for clinical genetics specialists. METHODS: By employing a cross-sectional survey design, the Clinical Genetics Committee of Shanghai Medical Association has conducted questionnaire surveys from March to April 2025 across 54 healthcare institutions in Shanghai (including 33 tertiary hospitals and 21 secondary hospitals). The survey involved administrative departments and medical personnel from 15 clinical specialties. The survey has covered current genetic disease diagnosis and treatment practices, relevant and specialised disease types, genetic department establishment, testing capabilities, personnel teams, and training requirements. RESULTS: The results revealed that 78.0% of clinical departments surveyed had treated patients with hereditary disorders. Shanghai possesses diagnostic and therapeutic expertise for over 95% of hereditary diseases listed in its rare disease catalogue, reflecting both the practical clinical demand for such conditions and the city's overall diagnostic and therapeutic strengths in this field. Nevertheless, significant disparities exist in the development of genetics departments across different tiers of healthcare institutions. Resources for genetic testing capabilities (including molecular, cellular, and biochemical testing) are also unevenly distributed across different tiers of hospitals. The survey further revealed that only 26.0% of departments believe that their current physician structure fully meets the diagnostic and treatment demands. Over 90% of departments consider standard training for clinical genetic specialists necessary, with 74.0% expressing willingness to participate in establishing training bases. Based on above findings and thorough deliberation, the Clinical Genetics Committee of the Shanghai Medical Association proposes advancing specialist training and discipline development through establishing a standard training system. The committee has drafted a three-year training protocol featuring a "joint training"-centered model, recommending a pilot-first, dynamically optimized strategy for steadily advancing training base development. CONCLUSION Shanghai faces substantial demand for genetic disease diagnosis and treatment, yet exhibits shortcomings in clinical genetics specialization development, resource allocation, and talent pipeline cultivation. To establish a standard training system holds significant practical importance and is underpinned by a broad demand.

ObjectiveTo perform metabolic associated fatty liver disease （MAFLD） screening among individuals attending community health institutions， to identify the patients at a low， moderate or high risk of advanced liver fibrosis based on fibrosis-4 index （FIB-4） and liver stiffness measurement （LSM） measured by liver transient elastography， and to implement stratified management. MethodsA cross-sectional study was conducted among 630 individuals attending Beijing Baizhifang Community Health Service Center from January to July 2024， and they were divided into MAFLD group and non-MAFLD group. According to body mass index （BMI）， the MAFLD group was further divided into lean MAFLD group （BMI<23 kg/m²） and non-lean MAFLD group （BMI≥23 kg/m²）. The above groups were compared in terms of demographic features， laboratory markers， hepatic steatosis， and LSM. Fibrosis risk stratification was performed for MAFLD patients based on FIB-4 and LSM， and a closed-loop management system involving referral to tertiary hospitals and follow-up at community health institutions was implemented. The Mann-Whitney U test was used for comparison of non-normally distributed continuous data between two groups， and the chi-square test or the Fisher’s exact test was used for comparison of categorical data between groups. ResultsThere were 445 individuals （70.6%） in the MAFLD group and 185 individuals （29.4%） in the non-MAFLD group. Compared with the non-MAFLD group， the MAFLD group had a significantly lower proportion of male individuals （χ²=4.299， P<0.05）， a significant reduction in the level of high-density lipoprotein cholesterol （Z=3.484， P<0.05）， and significant increases in body weight （Z=-7.366， P<0.05）， BMI （Z=-9.740， P<0.05）， waist circumference （Z=-6.397， P<0.05）， hip circumference （Z=-6.935， P<0.05）， alanine aminotransferase （ALT） （Z=-2.765， P<0.05）， fasting blood glucose （Z=-3.646， P<0.05）， triglyceride （TG） （Z=-6.569， P<0.05）， total cholesterol （Z=-2.033， P<0.05）， low-density lipoprotein cholesterol （Z=-2.935， P<0.05）， controlled attenuation parameter （CAP） （Z=-19.784， P<0.05）， and LSM （Z=-5.703， P<0.05）. Within the MAFLD group， there were 124 individuals （27.9%） in the lean MAFLD group and 321 individuals （72.1%） in the non-lean MAFLD group. Compared with the non-lean MAFLD group， the lean MAFLD group had significantly lower body weight （Z=-12.414， P<0.05）， BMI （Z=-16.363， P<0.05）， waist circumference （Z=-7.733， P<0.05）， hip circumference （Z=-8.595， P<0.05）， ALT （Z=-2.835， P<0.05）， aspartate aminotransferase （Z=-1.972， P<0.05）， TG （Z=-2.407， P<0.05）， CAP （Z=-4.429， P<0.05）， degree of steatosis （χ²=16.588， P<0.05）， and LSM （Z=-3.908， P<0.05）. Based on the results of FIB-4 and LSM， 76 patients at a moderate or high risk of liver fibrosis should be referred to a higher-level hospital for further management. ConclusionThe detection rate of MAFLD reaches 70.6% among the individuals attending community health institutions， among whom 76 （17.1%） should be referred to a higher-level hospital. Establishing a liver fibrosis risk stratification and management system based on FIB-4 and LSM among MAFLD individuals in communities provides a practical pathway for chronic disease management and referral system construction in community health institutions.

Water-soluble silver nanoclusters(DHLA-AgNCs)with red fluorescence emission were synthesized using silver nitrate(AgNO3)as silver source,dihydrolipoic acid(DHLA)as ligand and sodium borohydride(NaBH4)as reducing agent by one-pot method.Based on the selective quenching of DHLA-AgNCs by tetracycline(TC),a rapid and selective fluorescence analysis method for detection of TC was constructed by monitoring the fluorescence intensity change at 650 nm.Under the optimal detection conditions,the fluorescence quenching efficiency of DHLA-AgNCs showed good linear relationship with concentration of TC within the range of 10.0-120.0 μmol/L,and the limit of detection(LOD)was 0.39 μmol/L.This method was successfully applied to detection of TC in milk samples,with spiked recoveries ranging from 99.5%to 102.5%,and relative standard deviations(RSDs)less than 5%.This method had the advantages of simplicity,rapidity,strong specificity and low cost,and thus provided a simple and feasible strategy for selective detection of TC.

OBJECTIVE: Observational studies have found associations between inflammatory bowel disease (IBD) and the risk of dementia, including Alzheimer's dementia (AD) and vascular dementia (VD); however, these findings are inconsistent. It remains unclear whether these associations are causal. METHODS: We conducted a meta-analysis by systematically searching for observational studies on the association between IBD and dementia. Mendelian randomization (MR) analysis based on summary genome-wide association studies (GWASs) was performed. Genetic correlation and Bayesian co-localization analyses were used to provide robust genetic evidence. RESULTS: Ten observational studies involving 80,565,688 participants were included in this meta-analysis. IBD was significantly associated with dementia (risk ratio [ RR] =1.36, 95% CI = 1.04-1.78; I ² = 84.8%) and VD ( RR = 2.60, 95% CI = 1.18-5.70; only one study), but not with AD ( RR = 2.00, 95% CI = 0.96-4.13; I ² = 99.8%). MR analyses did not supported significant causal associations of IBD with dementia (dementia: odds ratio [ OR] = 1.01, 95% CI = 0.98-1.03; AD: OR = 0.98, 95% CI = 0.95-1.01; VD: OR = 1.02, 95% CI = 0.97-1.07). In addition, genetic correlation and co-localization analyses did not reveal any genetic associations between IBD and dementia. CONCLUSION Our study did not provide genetic evidence for a causal association between IBD and dementia risk. The increased risk of dementia observed in observational studies may be attributed to unobserved confounding factors or detection bias.

Objective:To investigate the gene expression level of fructose-bisphosphate aldolase A (ALDOA) in non-small cell lung cancer (NSCLC) tissues and the effect of ALDOA on NSCLC prognosis and immune cell infiltration in tumor microenvironment (TME).Methods:The clinical data of patients with lung adenocarcinoma and squamous cell carcinoma, the data of corresponding gene in tumor tissues and corresponding normal lung tissues in The Cancer Genome Atlas (TCGA) database, and the data of healthy population in the Genotype Tissue Expression (GTEx) database were collected in June 2023. Gene Expression Profile Interaction Analysis (GEPIA) 2.0 online tool was used to explore the expression differences of ALDOA at transcription level in NSCLC tissues and normal lung tissues, as well as NSCLC tissues of different stages; the expression of ALDOA was obtained through immunohistochemical staining in different pathological types of NSCLC and normal lung tissues from the Human Protein Atlas (HPA) database; the survival of patients with high and low expression of ALDOA in NSCLC tissues in TCGA database was evaluated by plotting Kaplan-Meier survival curves (differentiated by the median expression of ALDOA at transcription level in NSCLC samples), and log-rank test was used for comparing survival between groups. Using the Tumor Immune Estimation Resource (TIMER) 2.0 database, the CIBERSORT algorithm was applied to evaluate the correlation between ALDOA expression and immune cell infiltration levels in NSCLC tissues from the TCGA database. Further analysis of the correlation between ALDOA expression levels and programmed death receptor ligand 1 (PD-L1), matrix metalloproteinase 9 (MMP-9), vascular endothelial growth factor (VEGF), and various inflammatory factors in NSCLC tissues was conducted using the GEPIA 2.0 online tool to evaluate the impact of ALDOA expression levels on the tumor immune microenvironment.Results:The expression of ALDOA at transcription level in lung adenocarcinoma (483 cases) and lung squamous cell carcinoma (486 cases) tissues were higher than those in corresponding normal lung tissues (347 and 338 cases, respectively), and the differences were statistically significant (all P < 0.01). There was a statistically significant difference in the expression of ALDOA at transcription level among TNM stage Ⅰ, Ⅱ, Ⅲ, and Ⅳ NSCLC tissues ( F = 4.55, P = 0.004), and the expression level of ALDOA gradually increased with the increase of stage. In the HPA database, ALDOA protein stained by immunohistochemistry showed mild to moderate staining in normal lung tissues, while it showed severe staining in lung adenocarcinoma and squamous cell carcinoma tissue samples. Kaplan-Meier survival analysis showed that the overall survival of lung adenocarcinoma patients (239 cases) with high ALDOA expression was worse than that of patients with low ALDOA expression (239 cases) ( P < 0.001), and there was no statistically significant difference in disease-free survival between the two groups ( P = 0.140). There was no statistically significant difference in overall survival and disease-free survival between patients with high expression (241 cases) and low expression (241 cases) of ALDOA in lung squamous cell carcinoma (both P > 0.05). TIMER 2.0 database analysis shows that in lung adenocarcinoma, the expression of ALDOA at transcription level was negatively correlated with the levels of activated mast cells ( Rho = -0.209) and memory B cells ( Rho = -0.133), and positively correlated with the levels of resting mast cells ( Rho = 0.210) and resting natural killer cells ( Rho = 0.110), with statistically significant differences (all P < 0.05). In lung squamous cell carcinoma, the expression of ALDOA at transcription level was negatively correlated with the levels of activated mast cells ( Rho = -0.105), memory B cells ( Rho = -0.213) and CD8 + T cells ( Rho = -0.148), and positively correlated with the levels of resting mast cells ( Rho = 0.173), plasma B cells ( Rho = 0.174) and resting natural killer cells ( Rho = 0.136), with statistically significant differences (all P < 0.05). In NSCLC tissues, the expression of ALDOA at transcription level was negatively correlated with PD-L1 ( R = -0.11), interleukin (IL)-2 ( R = -0.31), IL-4 ( R = -0.14), IL-5 ( R = -0.10), IL-6 ( R = -0.12), and IL-10 ( R = -0.24) levels (all P < 0.001), positively correlated with MMP-9 ( R = 0.11) and VEGF ( R = 0.18) levels (both P < 0.001), and positively correlated with IL-9 ( R = 0.11) and VEGF ( R = 0.18) levels (both P < 0.001), but it was not correlated with IL-17 level ( R = -0.02, P = 0.540). Conclusions:The expression level of ALDOA is elevated in NSCLC tissues, and high ALDOA level in lung adenocarcinoma may indicate poor survival of patients. ALDOA may affect the levels of immune cell infiltration, tumor markers and inflammatory factors in TME, and it may be a potential biomarker for prognosis.

Antibody humanization is critical to reduce immunogenicity and enhance efficacy in the preclinical phase of the development of therapeutic antibodies originated from animal models.Computational suggestions have long been desired,but available tools focused on immunogenicity calculation of whole antibody sequences and sequence segments,missing the individual residue sites.This study introduces Site-specific Immunogenicity for Therapeutic Antibody(SITA),a novel computational framework that predicts B-cell immunogenicity score for not only the overall antibody,but also individual residues,based on a comprehensive set of amino acid descriptors characterizing physicochemical and spatial features for antibody structures.A transfer-learning-inspired framework was purposely adopted to overcome the scarcity of Antibody-Antibody structural complexes.On an independent testing dataset derived from 13 Antibody-Antibody structural complexes,SITA successfully predicted the epitope sites for Antibody-Antibody structures with a receiver operating characteristic(ROC)-area unver the ROC curve(AUC)of 0.85 and a precision-recall(PR)-AUC of 0.305 at the residue level.Furthermore,the SITA score can significantly distinguish immunogenicity levels of whole human antibodies,therapeutic antibodies and non-human-derived antibodies.More importantly,analysis of an additional 25 thera-peutic antibodies revealed that over 70％of them were detected with decreased immunogenicity after modification compared to their parent variants.Among these,nearly 66％antibodies successfully iden-tified actual modification sites from the top five sites with the highest SITA scores,suggesting the ability of SITA scores for guide the humanization of antibody.Overall,these findings highlight the potential of SITA in optimizing immunogenicity assessments during the process of therapeutic antibody design.

Cervical spinal cord injury without fracture-dislocation (CSCIWFD) is referred to as a special type of cervical spinal cord injury characterized by traumatic spinal cord dysfunction and no significant bony structural abnormalities on imagines. Duo to the high risk of missed diagnosis during the initial consultation, CSCIWFD may lead to progressive neurological deterioration or even complete paralysis, severely impacting patients′ prognosis. Currently, there are no established consensuses over the diagnosis and treatment of CSCIWFD, such as the lack of evidence-based standards for indications of non-surgical treatment and risk of secondary neurological injury, as well as debates over the optimal timing for surgical intervention and indications for different surgical approaches. To address these issues, the Spine Trauma Group of the Orthopedic Branch of the Chinese Medical Doctor Association organized experts in the relevant fields to formulate Diagnosis and treatment guideline for acute cervical spinal cord injury without fracture- dislocation in adults ( version 2025) . Based on evidence-based medicine and the principles of scientific rigor and clinical applicability, the guidelines proposed 11 recommendations covering terminology, diagnosis, evaluation treatment, and rehabilitation, etc., aiming to standardize the management of CSCIWFD.

Objective:To analysis of the latent profiles and influencing factors of body image in patients with postoperative oral cancer.Methods:From July 2024 to March 2025, a total of 332 patients with primary oral cancer confirmed by pathology, aged ≥18 years, and undergoing oral cancer surgery at Hunan Cancer Hospital were selected using simple random sampling and cluster sampling. Among them, 25 were female and 307 were male. The body image scale and the Rosenberg self-esteem scale were used to investigate the patients. The main indicators included the total scale scores and scores on various dimensions of body image, such as appearance evaluation and health focus, with particular attention to satisfaction with facial appearance and oral function.The correlation between self-esteem and body image was analyzed, and differences in scores were compared based on gender, age, self-esteem level, and surgical procedure.Results:Among the 332 patients, 93.4% (310/332) were married, and 6.6% (22/332) were unmarried, divorced, or widowed. A total of 84.3% (280/332) underwent flap transplantation surgery, while 15.7% (52/332) did not. The body image distress in the 332 patients could be categorized into a body image adaptation group [80.12% (266/332)] and a body image disorder group [19.88% (66/332)]. Unmarried/divorced/widowed status ( P=0.020), undergoing flap transplantation ( P=0.006), and self-esteem level ( P<0.001) were identified as influencing factors for postoperative body image disorder in oral cancer patients. Conclusions:Given the varying levels of body image concerns among oral cancer patients, healthcare providers can implement targeted, personalized nursing interventions based on their distinct categories and influencing factors.
