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.

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.

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 evaluate the efficacy of an online-to-offline(O2O)health education guided by the'Timing Theory'in improving self-management behaviours among the patients with glaucoma after day surgery.Methods In this randomised controlled study conducted between July and December 2022,70 patients with glaucoma after day surgery in our hospital were assigned to a control group and an experimental group,with 35 patients per group.Patients in control group received routine nursing care,while those in experimental group received O2O health education based on timing theory in addition to the routine nursing care.Outcomes were evaluated using the glaucoma awareness and knowledge questionnaire(GAKQ),self-efficacy to manage chronic disease scale(SEMCD)and glaucoma self-management questionnaire(GSMQ)at baseline,at 1 month and 3 months after surgery.Results A total of 32 patients in the experimental group and 27 in the control group completed the study.The generalised estimating equation(GEE)analysis showed a significant difference,respectively,in total score of GSMQ in interaction effect(F=8.408,P=0.015)and SEMC in time main effect(F=54.660,P<0.001).There were significant differences in total scores of GAKQ in time main effect,inter-group main effect and interaction effect(F=128.483,P<0.001;F=7.991,P<0.05;F=32.652,P<0.001,respectively).At one-month after intervention,the experimental group showed significantly higher GAKQ and SEMCD scores than the control group(Z=-2.004,P<0.05;Z=-2.029,P<0.05,respectively).At 1-and 3-months after intervention,the experimental group demonstrated significantly higher GAKQ scores(Z=-3.987,P<0.001;Z=-4.505,P<0.001,respectively).Conclusion The timing theory based O2O health education significantly improves knowledge of glaucoma,self-efficacy and self-management behaviours among day surgery patients and helps patients better cope with perioperative self-management over day surgery.

Objective:To investigate the use of targeted next generation sequencing (tNGS) for the detection of drug resistance in mycoplasma pneumoniae pneumonia (MPP) and analyze the clinical characteristics of MPP.Methods:The clinical data of patients with MPP who underwent bronchoalveolar lavage fluid tNGS at the Department of Respiratory and Critical Care Medicine, The Third People's Hospital of Hubei Province, Jianghan University from February 2022 to February 2024 were collected. According to inclusion and exclusion criteria, 80 patients with MPP were included in this study. The clinical data of the patients were retrospectively analyzed. tNGS of bronchoalveolar lavage fluid was performed to assess drug resistance in MPP. These patients were divided into a drug resistance group ( n = 55) and a non-drug resistance group ( n = 25) based on the presence or absence of the 23SrRNA:A2063G drug resistance mutation. Patient's clinical characteristics were compared between the two groups. The significant indicators from the univariate analysis were introduced into a binary logistic regression model to analyze the independent predictors of drug resistance and their predictive values. Results:The median age of patients with MPP was 38 years, with 53.75% (43/80) being female. Among the patients, 62.50% (50/80) had no underlying diseases, and 68.75% (55/80) exhibited drug resistance, while 42.50% (34/80) had mixed infections. The three most common clinical symptoms were cough (92.50%, 74/80), fever (62.50%, 50/80), and dyspnea (31.25%, 25/80). The most common imaging findings in MPP included patchy shadows (48.75%, 39/80) and consolidation shadows (42.50%, 34/80). Nodular shadows (7.50%, 6/80), tree-in-bud signs (5.00%, 4/80), ground-glass opacities (11.25%, 9/80), bronchial wall thickening (3.75%, 3/80), and pleural effusions (5.00%, 4/80) were not common. Bilateral lesions were present in 40.00% (32/80) of cases. In laboratory examinations, the median levels of inflammatory markers C-reactive protein (39.45 mg/L), procalcitonin (0.08 g/L), and serum amyloid A (168.31 mg/L) were increased. The median or mean levels of other indicators were within the normal range. There were no significant differences between the drug resistance and non-drug resistance groups in terms of gender, age, underlying diseases, clinical symptoms, length of hospital stay, mixed infection rate, mycoplasma pneumoniae (MP)-IgG positivity, MP-IgM level > 300 AU/mL, MP-DNA positivity, percentage of lymphocytes, platelet count, number of lymphocytes, and procalcitonin, D-dimer, prealbumin, lactate dehydrogenase, alanine aminotransferase, aspartate aminotransferase, and albumin levels as well as imaging findings (all P > 0.05). In the drug resistance group, the number of fever days, sequence number, white blood cell count, percentage of neutrophils, C-reactive protein level, and serum amyloid A level were as follows: 4 (0, 7), 24464.00 (2754.00, 43457.00), 7.35 (6.09, 9.84), 73.70 (67.20, 73.70), 39.82 (20.82, 70.40), and 205.40 (81.08, 338.30), respectively. These values were significantly higher than those in the non-drug resistance group [2 (0, 4.50), 658.00 (323.00, 7593.00), 6.12 (5.04, 7.20), 64.45 (58.58, 76.33), 35.63 (4.94, 57.36), 81.30 (12.51, 243.76), Z = -2.43, -4.67, -2.72, -2.36, -2.04, -2.37]. The albumin level in the drug resistance group was 41.50 (38.10, 44.30), which was significantly lower than that in the non-drug resistance group [43.55 (40.03, 46.05), Z = -2.07, P < 0.05]. In the binary logistic regression analysis, the sequence number was identified as an independent predictor of drug resistance. When the sequence number exceeded 1001, the area under the curve value was 0.827, with a sensitivity of 94.5% and specificity of 68.0%. Conclusions:The clinical manifestations of MPP are similar in both the macrolide-resistant and the non-resistant groups. However, the drug-resistant group exhibits a greater number of fever days, higher sequence numbers, and more severe inflammatory responses. The sequence number of MPP can be used to predict drug resistance. When the sequence number exceeds 1001, its predictive value for drug resistance is significantly higher.

The expert authority levels were 0.93 and 0.94, and the Kendall harmony coefficients were 0.28 and 0.38, respectively. The differences were statistically significant (both P<0.001). The final established plan included 5 primary indicators, 23 secondary indicators, and 47 tertiary indicators. Conclusions:The continuity of care plan for adolescent fixed orthodontic patients based on the timing theory is reliable and scientific, and can meet the continuity of care needs of patients at different stages, providing reliable clinical basis for carrying out continuity of care.

Objective:To explore the application efficacy of the continuous oral care program led by dental nurses in adolescent patients with fixed orthodontics and to provide a reference for continuous care to enhance the oral health level of patients.Methods:A randomized controlled trial was carried out in the Orthodontic Department of Shanghai Stomatological Hospital from June to December 2022. A total of 132 adolescent patients with fixed orthodontics were selected through the convenience sampling method and divided into the experimental group and the control group by the random number table method, with 66 patients in each group. The experimental group was provided with the continuous oral care program led by dental specialist nurses, while the control group received routine care. The intervention lasted for 12 months. The Oral Health Impact Scale, the Oral Health Self-Management Ability Questionnaire, and the plaque index were utilized to assess the intervention effect before and after the intervention.Results:A total of 65 participants in the experimental group completed the study, with an age of (14.41 ± 1.60) years, comprising 32 males and 33 females. In the control group, 64 participants completed the study, with an age of (14.15 ± 1.69) years, including 28 males and 36 females. Prior to intervention, there were no statistically significant differences in scores for oral health self-management ability, Oral Health Impact Profile-14, or total plaque index between the experimental and control groups (all P>0.05). Following intervention, the score for oral health self-management ability in the experimental group was (77.42 ± 11.70) points, significantly higher than (70.47 ± 17.49) points of the control group ( t = 2.65, P<0.05). Additionally, the score on the Oral Health Impact Profile-14 for the experimental group was (16.40 ± 3.45) points and their total plaque index was measured at 1.68 ± 0.55 both significantly lower than those recorded in the control group at (18.16 ± 3.79) points and a total plaque index of 1.92 ± 0.47 respectively ( t = - 2.75, - 2.55, both P<0.05). Conclusions:The implementation of the continuous oral care program led by dental specialist nurses is conducive to improving the oral health self-management ability of adolescent patients with fixed orthodontics, reducing dental plaque, improving oral cleanliness, and improving the oral health-related quality of life of patients.

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.
