Objective:To explore the intervention effects of the skill training for parents with autism child (STPAC) on toddlers with autism spectrum disorder (ASD).Methods:A multicenter non-randomized concurrent controlled study design was conducted. Thirty children with ASD aged 15-30 months, first diagnosed at the Children′s Hospital of Fudan University, the First Hospital of Jilin University, and Chengdu Women′s and Children′s Central Hospital from 2019 to 2020, were enrolled in the STPAC group. Thirty children with ASD who visited the same hospitals during the same period but refused the STPAC intervention were selected as the control group. The STPAC group received an 8-week intervention (3 h/week) followed by quarterly follow-ups for 1 year, while the control group voluntarily chose community-based routine interventions. The Griffiths development scales-Chinese (GDS-C) was used to assess the developmental levels, and the communication and symbolic behavior scales developmental profile infant-toddler checklist (CSBS-DP-ITC) was completed by the primary caregivers to evaluate social, language and symbolic behavior. The independent samples t-tests or Mann-Whitney U tests, etc.was used for inter-group comparison. The paired t-tests or Wilcoxon signed-rank tests, etc. was used for inter-group pre-post intervention comparison. Results:The STPAC group included 30 children (22 males and 8 females, aged (23.9±2.2) months), and the control group included 30 children (20 males and 10 females, aged (24.2±2.6) months). Before the intervention, there were no statistically differences in GDS-C development quotient (DQ) and CSBS-DP-ITC scores between groups (all P>0.05). After 1-year intervention, GDS-C DQ in personal-social, hearing-language, hand-eye coordination, performance domains of STPAC group and GDS-C DQ in personal-social, hearing-language domains of control group were all increased (all P<0.01). After 1-year intervention, CSBS-DP-ITC scores of both groups were all improved in socia, language, symbolic behavior, and total scores (all P<0.001). GDS-C DQ changes before and after 1 year of intervention in hearing-language, hand-eye coordination, performance domains of the STPAC group were all higher the those of control group (34(15, 48 vs. 10(-4, 39), 11±20 vs. -1±19, 23±25 vs. 8±22, all P<0.05). CSBS-DP-ITC scores changes before and after 1 year of intervention in social and total scores of the STPAC group were both higher the those of control group (10(5, 30) vs. 3(1, 7), 26±17 vs. 11±8, both P<0.001). Conclusion:Compared with the community routine interventions, the STPAC better improves the language, hand-eye coordination, visual-spatial, social communication, and play skills in ASD toddlers.

Objective: To establish a machine learning-based precision blood donor recruitment model at the county level and assess its generalizability and applicability. Methods: A retrospective study was conducted using blood donation and SMS recruitment data from the Taicang Branch of the Suzhou Blood Center between 2019 and 2024. Multiple machine learning algorithms were employed, including extreme gradient boosting, support vector machine, k-nearest neighbor, logistic regression, decision tree, random forest, and multilayer perceptron. These were combined with techniques such as synthetic minority oversampling, undersampling, and cost-sensitive learning (using MFE and MSFE loss functions). Model parameters were optimized through grid search to identify the best-performing model. Results: In a prospective comparative study against conventional methods, the machine learning models increased the recruitment success rate among high-willingness donors by an average of 129.15%, and the recruitment efficiency per SMS improved by 125.02% compared with the traditional method. Under full-scale SMS sending, the recruitment rate per SMS increased by 42.61%, and SMS sending efficiency improved by 31.77%, significantly enhancing recruitment performance. Conclusion: This study represents the first application of a machine learning-based precision donor recruitment model at the county-level in China. The precise recruitment framework not only improves recruitment efficiency and reduces recruitment costs but also demonstrates strong scalability and generalizability. It provides a scientific and feasible intelligent pathway to ensure the safety and sustainability of the blood supply.

Objective The aim of this study is to detect the expression of purinergic 2X7 receptor(P2X7R)and the NLRP3 inflammasome in benign prostatic hyperplasia(BPH)tissues and to analyze the clinical correlations.Methods Twelve patients undergoing surgery for BPH were enrolled.Based on the presence or absence of inflammatory cell infiltration in HE-stained tissue sections,the patients were divided into inflammation group and non-inflammation group.Preoperative routine ex-aminations excluded surgical contraindications,and International Prostate Symptom Score(IPSS)questionnaires,urinary flow rate measurements,expressed prostatic secretions(EPS)analysis,and prostate-specific antigen(PSA)tests were conducted.Prostate tissues obtained during surgery were subjected to HE staining,immunofluorescence/Western blot to detect the expression of NLRP3,P2X7R,Caspase-1,Cleaved-Caspase-1,IL-1 β,and TNF-α,and immunofluorescence to assess lymphocyte infiltra-tion.SPSS 26.0 software was used to analyze correlations between the expression levels of NLRP3 and P2X7R in prostate tissues and indicators including Caspase-1,Cleaved-Caspase-1,IL-1 β,TNF-α,lymphocyte count,IPSS score,urinary flow rate,EPS,and PSA.Results In BPH tissues,the expression levels of NLRP3 and P2X7R were positively correlated(P＜0.05).The ex-pression levels of NLRP3 and P2X7R were positively correlated with Caspase-1,Cleaved-Caspase-1,IL-1 β,TNF-α,and lym-phocyte count(P＜0.05).NLRP3 and P2X7R expression levels were positively correlated with white blood cell count in EPS,but showed no correlation with IPSS score,lecithin body count in EPS,maximum urinary flow rate and PSA(P＜0.05).Conclusion P2X7R and NLRP3 in prostate tissues exacerbate local inflammatory responses,which may be an important mecha-nism in BPH development.However,they are not correlated with IPSS score,lecithin body count in EPS,maximum urinary flow rate and PSA.

Objective:To compare the efficacy, safety, and influencing factors among children with hepatitis B virus e antigen (HBeAg)-positive chronic hepatitis B (CHB) who received short-term therapy with pegylated interferon alfa-2a (Peg-IFNα-2a) or continuous therapy with entecavir (ETV).Methods:Quantitative data were compared using analysis of variance to compare the differences between groups. Enumeration data were compared by χ2 test (or Fisher's exact test). Univariate and multivariate logistic regressions were used to analyze the influencing factors. Results:Peg-IFNα-2a, ETV, and untreated group had HBsAg clearance rates of 46.2%, 5.3%, and 0 after 52 weeks of therapy, respectively. HBsAg clearance in the patients' group with Peg-IFNα-2a and ETV was all accompanied by anti-HBS positive conversion, and the difference was statistically significant ( χ2=13.616, P=0.001). Peg-IFNα-2a group was followed-up for 104 weeks. Peg-IFNα-2a, ETV, and the untreated group had HBsAg clearance rates of 46.2%, 10.5%, and 0%, respectively, and the differences were statistically significant ( χ2=11.056, P=0.004). Only one of the two children with HBsAg clearance in the ETV group had achieved anti-HBs antibodies, and the difference was statistically significant ( χ2=13.616, P=0.001). Univariate and multivariate logistic regression analysis showed that HBsAg clearance was associated with age and antiviral therapy. During treatment, adverse events such as fever ( n=4, 30.8%), rash ( n=4, 30.8%), fatigue ( n=1, 7.7%), leukopenia ( n=7, 53.8%), arthritis ( n=1, 7.7%), and alopecia ( n=3, 23.1%) were observed in the Peg-IFNα-2a group, while none were observed in the ETV group. Conclusion:Peg-IFNα-2a antiviral therapy produced higher HBsAg clearance than ETV in five-year-old and younger children with HBeAg-positive CHB, while ETV had fewer adverse events and was safer than Peg-IFNα-2a.

Objective:To systematically evaluate the efficacy of hyperbaric oxygen (HBO) combined with comentional drugs in the treatment of angina pectoris caused by coronary heart disease with meta-analysis.Methods:The data on clinical randomized controlled trials (RCTs) of HBO combined with conventional drugs in the treatment of angina pectoris due to coronary heart disease in Cochrane Library, Medline, Embase, Wanfang Data, Cqvip, China National Knowledge Infrastructure (CNKI) were collected, and the time period was from the respective founding day of the above databases to October 2020. Three researchers independently screened the collected RCTs, extracted relevant data, and evaluated the quality of the trials. RevMan 5.4 software was used for meta-analysis.Results:A total of 11 RCTs were included in this study. Meta-analysis results showed that the HBO group was better than the control group in terms of total clinical effectiveness, alleviation of angina symptoms, and improvement in ECG performance.Conclusion:HBO combined with conventional drugs can better alleviate the symptoms of angina pectoris due to coronary heart disease and improve their ECG performance. In the future, high-quality RCTs need to be carried out to verify the conclusion of this study.

Objective:To compare the baseline difference in the quantitative hepatitis B core antibody levels (qAnti-HBc) between non-response and response group in children with HBeAg-positive chronic hepatitis B (CHB) who received antiviral therapy, and further explore the proportion and functional activity of CD8 + memory T lymphocyte subsets with different qAnti-HBC levels in peripheral blood of children.Methods:The baseline anti-HBc quantification (qAnti-HBc) levels of 85 children with HBeAg-positive CHB who visited the Department of Infectious Diseases, Children's Hospital of Chongqing Medical University from June 2018 to December 2020 were detected retrospectively. The relationship between the baseline qAnti-HBc level and HBeAg serological response in 37 children who received antiviral therapy was analyzed. The proportion of CD8 + memory T lymphocyte subsets and the secretion levels of interferon (IFN) γ, and tumor necrosis factor (TNF) α in peripheral blood of 59 children at baseline were detected by flow cytometry. The relationship between qAnti-HBc level and the proportion and functional activity of CD8 + memory T lymphocyte subsets was analyzed. Pearson’s Chi-square test was used to compare the count data. Mann-Whitney U test or Kruskal-Wallis test was used to compare measurement data between two or more groups, and Spearman’s rank correlation analysis was used for the correlation between continuous variables. Results:Among 37 children who received entecavir (ETV, 21/37 cases) or pegylated interferon (Peg-IFN, 16/37 cases), 18 cases had developed HBeAg seroconversion (10/ 21 cases in the ETV group, 8/16 cases in the Peg-IFN group). The baseline qAnti-HBc level was significantly higher in the response group [4.71 (4.64~4.81) log 10IU/ml] than the non-response group children [4.54 (4.45~4.64) log 10IU/ml, Z = -3.316, P = 0.001]. The proportion of CD8 + Tem, CD38 +CD8 + Tem, CD38 +CD8 + Temra cells and the levels of IFNγ and TNFα secreted by CD8 + T lymphocytes were significantly higher in the high-qAnti-HBc group than the low-qAnti-HBc group ( P < 0.05). The proportion of CD8 + Tem, CD38 +CD8 + Tem and CD38 +CD8 + Temra cells was significantly higher in ALT > 1× upper limit of normal value (ULN) group than ALT≤1×ULN group ( P < 0.05). However, there were no significant differences in the levels of IFNγ and TNFα secreted by CD8 + T lymphocytes between the two groups ( P > 0.05). Spearman’s correlation analysis showed that qAnti-HBc was positively correlated with the proportion of CD8 + Tem, CD38 +CD8 + Tem, CD38 +CD8 + Temra cells and the level of IFNγ secreted by CD8 +T lymphocytes ( P < 0.05). Additionally, ALT was only positively correlated with the proportion of CD38 +CD8 + TEM and CD38 + CD8 + Temra cells ( P < 0.05). Conclusion:Raised baseline qAnti-HBc level is related to the HBeAg serological response to antiviral therapy in children with CHB. Peripheral blood effector CD8+ T lymphocytes of CHB children with higher qAnti-HBc show stronger phenotype and functional activation characteristics, which may shed some light on the underlying immune mechanism related to antiviral therapy efficacy in children with CHB.
