Abstract Adverse childhood experiences (ACEs) exposure is a pressing and severe global public health issue. Children and adolescents exposed to multiple ACEs are highly susceptible to toxic stress and impaired physiological functioning, which significantly jeopardize their physical and mental health. Effective prevention and intervention strategies can reduce the prevalence of ACEs and mitigate their severe impacts, thereby minimizing the long term detrimental consequences on future outcomes. The review provides a comprehensive review of intervention strategies across four dimensions: individual, family, school, and public services/policy, so as to establish a theoretical foundation for implementing effective interventions for children and adolescents exposed to adverse childhood experiences.

Background/Aims: Dysregulated cholesterol metabolism is a hallmark of hepatocellular carcinoma (HCC) that drives tumor initiation and progression. However, clinical targeting of cholesterol metabolism has yielded limited benefits due to stringent feedback in tumor cells. Identifying a central mediator capable of restoring cholesterol homeostasis within the cell’s intrinsically fine-tuned regulatory framework is urgently needed. Methods: We integrated a proteomic dataset from patients with cholesterol-dysregulated HCC into a global cholesterol metabolic regulatory network to identify potential therapeutic targets for disrupted cholesterol homeostasis. The prognostic significance of the candidate targets was further validated in an independent cohort through immunohistochemistry. Functional and mechanistic studies were conducted in vitro using HCC cell lines and in vivo using mouse models. The pharmacological efficacy of the candidate agent was evaluated in both subcutaneous and orthotopic HCC mouse models. Results: ER lipid raft-associated 1 (ERLIN1), a pivotal regulator of cholesterol metabolism reprogramming, was identified as an independent favorable prognostic indicator in HCC. ERLIN1 constrains HCC progression both in vitro and in vivo by stabilizing the INSIG1–SCAP–SREBP2 axis and maintaining the metabolic balance of intracellular cholesterol. Under hypoxia, impaired factor-inhibiting hypoxia-1-dependent hydroxylation of ASB11 at asparagine residues 90 and 92 enhances ASB11-mediated ERLIN1 degradation. Pharmacological targeting of this axis using zoledronic acid (ZoA) attenuated HCC progression by weakening the ASB11–ERLIN1 interaction and restoring cholesterol homeostasis. Conclusions ERLIN1 represents a druggable metabolic vulnerability in cholesterol-dysregulated HCC. Targeting the ASB11–ERLIN1 axis with the clinically approved ZoA reestablishes cholesterol homeostasis and offers a promising therapeutic strategy to overcome the current limitations of cholesterol-targeted HCC therapies.

Objective: To conduct screening for rare blood types within important blood group systems for the Chinese population, such as Rh, Duffy, Kidd, P1Pk, Diego, and MNS, in the Guangzhou region, and to establish a corresponding rare blood type database and physical repository. Methods: The saline medium microplate method was used to screen blood donors with the ccDEE phenotype combined with either Jk(a-) or Jk(b-). The polybrene microplate method was employed to screen for donors with Fy(a-), s(-), Lu(b-), Di(b-), k(-), and p phenotypes. The urea lysis microplate method was applied to screen for the Jk(a-b-) phenotype. A high-resolution melting (HRM) curve method was established for screening some donors with the Di(b-) phenotype. Subsequently, expanded phenotyping of antigens in the Rh, Kidd, MNS, Duffy, P1Pk, Lewis, Kell, and Lutheran blood group systems was performed on identified rare blood type donors using monoclonal antibodies. The test results are entered into the Rare Blood Type Bank Management System of the Guangzhou Blood Center, enabling functions such as confirmation reminders and cryopreservation storage when the donor donates again. Red blood cells of rare blood types are processed into frozen red blood cells for long-term storage. Results: Among voluntary blood donors, 16 cases of the ccDEE combined with Jk(a-) phenotype were identified (0.221 7%, 16/7 216); 10 cases of the ccDEE combined with Jk(b-) phenotype (0.138 6%, 10/7 216); 78 cases of the Fy(a-) phenotype (0.169 5%, 78/46 012); 39 cases of the Lu(b-) phenotype (0.138 2%, 39/28 214); 31 cases of the s(-) phenotype (0.081 8%, 31/37 913); 22 cases of the Di(b-) phenotype (0.029 9%, 22/73 691); 30 cases of the Jk(a-b-) phenotype (0.010 1%, 30/298 250); and 1 case of the k(-) phenotype (0.001 3%, 1/77 382), which was further identified as KELnull phenotype (K0). No p phenotype donors were identified (0/88 528). A total of 228 units of frozen red blood cells were prepared. The screening results were compared and analyzed with rare blood type data from other regions. Conclusion: This study, through a combination of different screening methods, significantly improved the efficiency of rare blood type screening while remaining cost-effective. By conducting large-scale screening and performing data informatization processing, a database and physical repository of rare blood types in the Guangzhou region were successfully established. This provides a strong guarantee for the timely supply of blood to patients with difficult-to-match and rare blood types in the region, effectively enhances the level of transfusion safety in the region, and offers a practical paradigm for constructing a comprehensive blood transfusion support system.

Objective:To explore the association between healthy lifestyle and co-morbidity of overweight/obesity and myopia in adolescents.Methods:Based on the Shanghai Municipal Dynamic Cohort of Student Common Diseases, we used the group-based trajectory model (GBTM) to establish a model for the development of adolescents' healthy lifestyle trajectories aged 11-14 years and the Cox proportional hazard regression model to assess the effects of different healthy lifestyles on the co-morbidity of overweight/obesity and myopia in adolescents.Results:A total of 2 331 adolescents were included in the analysis. The average follow-up time was 1.87 years, with age of (11.44±0.45) years at the initial follow-up, among 1 106 boys and 1 225 girls. During the 2-year follow-up period, the incidence rates of overweight/obesity, myopia, and co-occurrence of overweight/obesity and myopia were 25.9%, 77.0%, and 13.7%, respectively. GBTM identified 3 healthy lifestyles: the unhealthy group (7.3%), the relatively healthy group (50.2%), and the healthy group (42.5%). The risk of overweight/obesity was lower in the relatively healthy group than in the unhealthy group ( HR=0.694, 95% CI: 0.508-0.947). There was no statistically significant association between the GBTM lifestyle subgroups and myopia ( P>0.05). The risk of co-occurrence of overweight/obesity and myopia was lower in both relatively healthy group and healthy group than in the unhealthy group (relatively healthy group: HR=0.515, 95% CI: 0.348-0.763; healthy group: HR=0.571, 95% CI: 0.384-0.849). Sensitivity analyses showed this result to be stable for myopia, overweight/obesity and myopia co-morbidities. Conclusion:Persistent unhealthy lifestyle increases the risk of overweight/obesity and myopia co-occurrence in adolescents.

Objective To construct a health management information service platform for glaucoma patients to achieve continuous care.Methods The architecture of the health management information service platform for glaucoma patients was designed,and the platform was developed and implemented.Results A WeChat mini program-based health management information service platform was developed,consisting of a medical staff interface,a patient interface,and a backend management center.The platform integrates functions such as whole-process disease tracking,surgical management,medication and follow-up record-keeping with reminders,communication for follow-ups,and health education.From March 2021 to March 2024,the platform registered 2764 patients and 45 medical staff,with a total of 10 947 platform interactions.An overall assessment with the post-study system usability questionnaire yielded a mean score of 28.2,indicating good user experience.Conclusion This platform realizes closed-loop management for continuous care of glaucoma patients and provides a practical reference for the development and exploration of health management information service platforms.

Objective To investigate clinical therapeutic value of combined posterior nasal nerve and anterior ethmoidal nerve ablation in patients with nasal septal deviation and moderate to severe persistent allergic rhinitis.Methods A total of 47 patients diagnosed with nasal septal deviation and moderate to severe persistent allergic rhinitis from April to December 2024 were divided into two groups.The control group(n=22)underwent septoplasty and bilateral inferior turbinate out-fracture,with postoperative symptom control managed by budesonide nasal spray.The experimental group(n=25)received the same septoplasty and turbinate surgery,supplemented by bilateral posterior nasal nerve and anterior ethmoidal nerve ablation.Symptom improvement was compared between groups by using the Visual Analogue Scale(VAS)and Rhinoconjunctivitis Quality of Life Questionnaire(RQLQ)scores preoperatively and3 months postoperatively.Results The operation time of the control group was(36.3±5.9)min,significantly shorter than that of the experimental group[(59.4±6.6)min,t=12.496,P=0.000].Both groups of patients showed significant improvement in VAS and PQLQ scores for nasal symptoms such as nasal congestion,runny nose,sneezing,and itching at 3 months after surgery compared to preoperative levels(all P=0.000).The mean VAS score of the four symptoms in the control group was(4.6±0.9)points at3 months after surgery,which was significantly lower than that before surgery[(6.3±1.1)points,t=9.796,P=0.000].The mean VAS score of the four symptoms in the experimental group was1.0(0.3-4.3)points at3 months after surgery,which was significantly lower than that before surgery[7.0(4.5-9.0)points,Z=-4.376,P=0.000].The improvement rate of the VAS score in the experimental group was(82.4±14.2)%,significantly higher than that in the control group[(26.9±11.7)%,t=14.510,P=0.000].At3 months after surgery,the RQLQ score of the control group[(2.3±0.8)points]was significantly lower than that before surgery[(3.3±0.8)points,t=10.055,P=0.000].The RQLQ score of the experimental group after surgery was 1.4(0.8-3.5)points,which was significantly lower than the preoperative score[3.6(1.5-6.1)points,Z=-4.373,P=0.000].The improvement rate of RQLQ score in the experimental group was(53.0±14.6)%,significantly higher than that in the control group[(30.2±13.4)%,t=5.555,P=0.000].Conclusion Postnasal nerve and anterior ethmoidal nerve ablation combined with nasal septal deviation correction can significantly improve nasal symptoms and quality of life in patients with nasal septal deviation complicated with moderate to severe allergic rhinitis compared with simple nasal septal deviation correction,but the operation time is prolonged.

OBJECTIVE To explore the differences in the clinical laboratory test indexes between the patients with two different TCM syndrome types of eczema(dampness-heat infiltration type and non-dampness-heat infiltration type)and observe the distribution and drug resistance rate of pathogens isolated from the skin lesions so as to pro-vide bases for syndrome differentiation and reasonable use of antibiotics.METHODS A total of 180 patients with eczema who were positive for bacterial culture of skin secretions and were treated in Beijing Hospital of Traditional Chinese Medicine from Jan.2021 to Dec.2023 were enrolled in the study and were divided into the dampness-heat infiltration group with 134 cases and the non-dampness-heat infiltration group with 46 cases.The data of clini-cal laboratory test indexes were collected from the two groups of patients,the secretion specimens were sampled from the skin lesion sites,the isolated pathogens were identified by VITEK 2 Compact automatic microorganism analysis system,and the drug susceptibility testing was performed.RESULTS The direct bilirubin level of the dampness-heat infiltration group was(3.99±1.62)umol/L,higher than(3.46±1.12)umol/L of the non-damp-ness-heat infiltration group(P＜0.05),but both were in the normal range;there were no significant differences in other test indexes between the two groups.Totally 180 strains of pathogens were isolated from the 180 patients with eczema,156(86.67％)of which were gram-positive bacteria;Staphylococcus aureus(98 strains),Staphy-lococcus epidermidis(29 strains)and Staphylococcus haemolyticus(15 strains)were the predominant species of the gram-positive bacteria.The gram-negative bacteria accounted for 12.22％(22 strains).The drug resistance rate of the S.aureus strains to penicillin was up to 82.65％,and the isolation rate of methicillin-resistant Staphy-lococcus aureus(MRSA)was 12.24％(12/98);the drug resistance rates of the S.epidermidis strains to penicil-lin and erythromycin were 75.86％,and the drug resistance rate of the S.haemolyticus strains to erythromycin was 100.00％.CONCLUSIONS The gram-positive bacteria(dominated by the S.aureus)are dominant among the pathogens isolated from the skin lesion specimens of the eczema patients and are highly resistant to penicillin and erythromycin.The isolation rate of MRSA is relatuvely low.There is limited clinical significant difference in the direct bilirubin between the two groups.It is necessary to further explore more reliable indexes for syndrome dif-ferentiation.

Objective:To develop an artificial intelligence (AI)-based platelet review strategy to identify abnormal platelet histograms with no significant difference between initial impedance platelet count (PLT-I) and PLT-F results.Methods:This study included 5 119 routine blood analysis in Nanfang Hospital of Southern Medical University and its Ganzhou branch from July 2023 and March 2024. Specimens exhibiting abnormal platelet histograms and an initial platelet count >40×10?/L underwent review using the fluorescent platelet count (PLT-F) channel. Consistency of the results was defined as a difference between impedance platelet count (PLT-I) and PLT-F less than ±20% of the PLT-F results. A deep learning model was developed using platelet and red blood cell histogram data from a training set of 3 807 specimens. The model′s diagnostic performance was evaluated on an independent external validation set ( n=805) using receiver operating characteristic (ROC) curve analysis. Changes in the number of reviewed samples and sample turnaround time were analyzed to assess its clinical utility. Results:The deep learning model based on platelet and red blood cell histograms achieved an area under the ROC curve (AUC) of 0.854 in the training set. At a cutoff value of 0.1, the sensitivity was 0.954 and specificity was 0.358. The model could reduce review by 16.80% (190/1 131). In the validation set, the AUC was 0.805, with a sensitivity of 0.955 and specificity of 0.307, corresponding to a reduction of 17.41% (47/270) in reviewed specimens.Conclusion:The platelet review prediction model developed based on deep learning technology can efficiently identify samples with consistent results before and after review, reducing unnecessary reviews and shortening specimen testing time, thereby improving the efficiency of platelet test.

Objective:To analyze the relationship between clinicopathological features and germline mismatch repair (MMR) gene variants in endometrial cancer patients and to evaluate the clinical utility of germline multi-gene panel testing.Methods:This single-center, retrospective case series study included 100 endometrial cancer patients treated in Zhongshan Hospital, Fudan University between July 2022 and February 2024. We collected clinicopathological data and tumor molecular testing results. 61 cancer susceptibility genes were tested using next-generation sequencing, and the associations between the detection rate of germline variants and the clinicopathological characteristics in endometrial cancer patients were explored.Results:Among 100 patients, 28% (28/100) were found to have pathogenic variants in cancer susceptibility genes, of which 20 patients carried germline MMR gene variants and the remaining 8 patients carried variants in other cancer susceptibility genes. Of the 20 patients diagnosed with Lynch syndrome, only 40% (8/20) met the Chinese family history criteria for Lynch syndrome. Among 53 patients with intact MMR protein expression, 1 patient was identified with a germline MMR gene variant. In the 14 Lynch syndrome patients with confirmed microsatellite status, 5/14 of those showed low microsatellite instability or microsatellite stability. Germline multi-gene panel testing in all endometrial cancer patients additionally identified 1 Lynch syndrome patient and 8 patients with non-Lynch hereditary cancers.Conclusion:Current clinical screening criteria may miss some endometrial cancer patients with Lynch syndrome. Compared with traditional screening pattern, germline multi-gene panel testing not only improves the detection rate of Lynch syndrome in endometrial cancer patients but also identifies other hereditary cancer predispositions.

Objective To investigate the changes in the gut microflora(GM)composition and metabo-lites in children with allergic rhinitis(AR)based on high-throughput sequencing technology.Methods From December 2023 to May 2024,11 preschool children with allergic rhinitis(AR)who visited the pediatric outpa-tient department of Shantou University Medical College Longgang Maternal and Child Health Hospital Clini-cal College(Longgang District Maternal and Child Health Hospital)were selected as the AR group,and 21 healthy children of the same age who underwent physical examinations in the child health care department during the same period were selected as the control group.Fecal samples were collected from both groups,and DNA was extracted and amplified.High-throughput sequencing technology was used to analyze the composi-tion of gut microbial genes,and the differences in gut microbiota composition and metabolites between the two groups were compared.Results Compared with the control group,the AR group had a higher Shannon index,with a significant increase in the abundance of Proteobacteria and Saccharibacteria.The relative abundance of Veillonella,Enterococcus,Escherichia coli/Shigella,Haemophilus,and Streptococcus was significantly high-er,while the relative abundance of Lachnospira,Anaerostipes,Enterobacteriaceae,Anaerobacterium,and Eu-bacterium was significantly lower(P＜0.05).There were statistically significant differences in the principal components of GM metabolites between the two groups(P＜0.05).A total of 2 540 different metabolites were identified,of which 1 185 metabolites were significantly increased,20 metabolites were significantly de-creased,and 1 335 metabolites showed no significant changes.Variable importance in projection(VIP)analy-sis revealed 30 significantly different metabolites.Compared with the control group,2 fecal metabolites were significantly downregulated in the AR group,specifically 3-furanmethanol glucoside and membrane heptosyl A.Conclusion The gut microbiota of preschool children with AR has undergone significant changes,which are related to inflammation and immune function.
