ObjectiveTo establish an educational intervention framework of electronic picture books for children with autism spectrum disorder (ASD) based on Creative Problem Solving (CPS) model, and observe the effect on social function. MethodsElectronic picture books were designed using CPS model, including the program of reading, interactive animation design and associated artistic activities. From March to June, 2023, 24 children with mild to moderate ASD were recruited from Maanshan Institute of Special Education, and randomly assigned into experimental group 1 (CPS-based cognitive picture book interventions, n = 8), experimental group 2 (CPS-based social picture book interventions, n = 8) and control group (Bloom's Taxonomy-based picture book interventions, n = 8), and received the interventions for four weeks, with a total of twelve times. They were assessed with speech, social, perceptual and health behavior using Autism Treatment Evaluation Checklist (ATEC) before and after treatment, and the differences were calculated. ResultsThere was a significant difference among the groups in the social and perceptual scores differences (F > 4.344, P < 0.05) and a near-significant difference in the health behaviour score difference (F = 2.921, P = 0.076). Post Hoc test showed that the differences in social scores were higher in both experimental groups than in the control group (P < 0.05); the difference in perceptual scores was significantly higher in experimental group 1 than in experimental group 2 (P < 0.01), but there was no significant difference with the control group (P > 0.05); the difference in health behavior scores was higher in experimental group 2 than in the control (P < 0.05), and the difference in experimental group 1 was slightly higher than in the control group (P = 0.072). ConclusionElectronic picture book interventions based on the CPS model may be more effective in enhancing social, perceptual and health behavior in children with ASD, but there may be differences among models.

Objective: To investigate the clinical efficacy and safety of pudendal nerve modulation (PNM) in the treatment of female pudendal neuralgia (PN)，so as to promote the clinical application of this technique. Methods: A retrospective analysis was conducted on 20 female PN patients who failed conservative treatment at Gongli Hospital during Nov.2020 and Oct.2023.All patients underwent simultaneous PNM and sacral nerve modulation (SNM) with the assistance of 3D printing navigation.Dual-stage test electrodes for PNM and SNM were implanted，followed by alternate therapeutic trial for each modality.Secondary conversion rates and longitudinal outcomes，including visual analogue score (VAS)，patient health questionnaire-9 (PHQ-9)，and quality of life (QoL) scores were compared preoperatively，post-stage Ⅰ，and at 3，6，and 12 months post-stage Ⅱ. Results: All operations were successful.After the trial phase，the secondary conversion rate for PNM was significantly higher than that for SNM; 16 patients (16/20，80%) chose the second-phase PNM implantation surgery，3 (3/20，15%) chose second-phase SNM implantation，and 1 (1/20，5%) had electrodes removed due to ineffective results from both trials.Further assessment revealed that the improvements in VAS，PHQ-9，and QoL scores for PNM patients were significantly better than those for SNM patients after the first phase of surgery and at 3，6 and 12 months after the second-phase conversion (P<0.05).No complications such as electrode migration or infection were observed during the follow-up of 12-15 months. Conclusion: PNM provides more effective relief of pain symptoms and improvements in depressive states for female PN patients compared to SNM.With the assistance of 3D printing navigation，the operation is simple and safe，and offers stable therapeutic effects.It is worthy of clinical promotion and application.

Objective To investigate the effects of calcitriol intervention on PI3K/AKT signaling pathway and wound healing in rats with diabetic foot ulcer(DFU).Methods Thirty-two male SD rats were divided into normal control(Con)group,DFU group,calcitriol low dose(L)group and calcitriol high dose(H)group.A circular wound of 5 mm in diameter and deep to the fascia was made on the dorsum of the left foot of rats in each group.HE staining was used to evaluate the histopathological changes of the wounds.Immunohistochemical method was selected to compare the distribution of CD34-positive cells and the expression of p-PI3K and p-AKT in traumatic tissues of each group.ELISA was adopted in the detection of serum IL-6,IFN-γ,TNF-α and IL-7.RT-PCR was used to detect the mRNA expression of PI3K and AKT in each group,and western blot was used to detect the protein expression of PI3K,p-PI3K,AKT,p-AKT and VEGF.Results Compared with Con group,the expressions of IL-6,IFN-γ,TNF-α,IL-7,CD34,PI3K mRNA,AKT mRNA,p-AKT protein,p-PI3K protein,p-PI3K/PI3K,p-AKT/AKT increased,while PI3K protein expression decreased in DFU,L and H groups(P<0.05),VEGF and AKT protein expression decreased in DFV and L groups(P<0.05).Compared with DFU group,the expressions of VEGF,AKT and PI3K protein increased(P<0.05),while the expressions of p-PI3K/PI3K,p-AKT/AKT decreased in L and H groups(P<0.05),IL-6 decreased in L group(P<0.05),and CD34 expression increased in H group(P<0.05),while IL-6,IFN-γ,TNF-α and IL-7,PI3K mRNA,AKT mRNA,p-AKT protein and p-PI3K protein expression decreased(P<0.05).Compared with L group,the expressions of CD34,VEGF,AKT and PI3K protein increased(P<0.05),while IL-6,PI3K mRNA,AKT mRNA,p-AKT protein,p-PI3K protein,p-PI3K/PI3K and p-AKT/AKT decreased in H group(P<0.05).Conclusions Calcitriol intervention may reduce the activity of the PI3K/AKT signaling pathway,inhibit inflammation,promote neovascularization,and facilitate wound healing in rats with DFU.

Purpose: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can infect the human placenta and has been shown to have an adverse effect on Doppler ultrasound parameters and placental features. However, the specific effects of the SAS-CoV-2 infection on the fetal-placental unit in pregnant women remain unclear. The aim of this systematic review and meta-analysis was to evaluate the impact of SARS-CoV-2 infection on Doppler ultrasound and placental findings in pregnant women. Methods: A systematic search was conducted using four electronic databases (PubMed, Embase, Scopus, and Cochrane Library) to select publications published in peer-reviewed journals written in English. Odds ratios (ORs) were calculated, along with their 95% confidence intervals (CIs). Heterogeneity was assessed using Cochrane Q and I² statistics and the appropriate P-value. The analysis used RevMan 5.3. Results: This meta-analysis included 1,210 pregnant women from 10 case-control studies. SARS-CoV-2–infected pregnant women exhibited higher likelihoods of placental abnormalities (OR, 2.62; 95% CI, 1.66 to 4.13), aberrant Doppler values (OR, 1.95; 95% CI, 1.16 to 3.27), an abnormal cerebroplacental ratio (OR, 2.68; 95% CI, 1.52 to 4.75), altered fetoplacental circulation (OR, 1.56; 95% CI, 1.07 to 2.28), and increased placental thickness and placental venous lakes (OR, 1.85; 95% CI, 1.25 to 2.72). Conclusion According to this meta-analysis, pregnant women infected with SARS-CoV-2 are more likely to experience altered Doppler ultrasonography parameters and placental abnormalities, including increased placental thickness, placental venous lakes, altered fetoplacental circulation, and cerebroplacental ratio. However, the limited number of case-control studies requires larger sample sizes to validate and enhance the evidence.

Objective To explore the pulmonary ultrasound manifestations of pediatric infectious pneumonia and its combined diagnostic value with serum amyloid protein A(SAA)/hypersensitive C-reactive protein(hs-CRP)and procalcitonin(PCT).Methods A tatol of 107 children with infectious pneumonia admitted to the 903rd Hospital of the Joint Logistics Support Force of the People's Liberation Army of China from January 2019 to June 2023 were selected as the research group,and 50 healthy children who underwent physical examinations during the same period were selected as the control group.Both groups of children underwent lung ultrasound examination to analyze the ultrasound manifestations of children with infectious pneumonia,compare SAA/hs-CRP and PCT,and analyze the diagnostic value of lung ultrasound combined with SAA/hs-CRP and PCT detection for pediatric infectious pneumonia.Results Among 107 children with infectious pneumonia,104 were diagnosed positive by lung ultrasound,with a positive rate of 97.20％.The lung ultrasound score,SAA/hs-CRP,and PCT of the study group were higher than those of the control group(P＜0.05).The lung ultrasound score,SAA/hs-CRP,and PCT in children with severe infectious pneumonia were higher than those in mild cases(P＜0.05).The diagnostic efficacy of lung ultrasound combined with SAA/hs-CRP and PCT detection for pediatric infectious pneumonia is superior to that of individual detection,with a curve area of 0.923,sensitivity and specificity of 92.30％and 87.98％,respectively.The lung ultrasound score is positively correlated with SAA/hs-CRP and PCT(P＜0.05).Conclusion Pulmonary ultrasound can display the characteristics of pulmonary lesions in children with infectious pneumonia.The ultrasound manifestations of children are mostly abnormal pleural lines,increased B-lines,and pulmonary consolidation.Combined detection with SAA/hs-CRP and PCT can further improve the diagnostic efficiency of pediatric infectious pneumonia.

β-elemene has been observed to exert inhibitory effects on a multitude of tumors,primarily through multiple pathways such as the inhibition of cancer cell proliferation and the induction of apoptosis.The present study is designed to elucidate the role and underlying mechanisms of β-elemene in the thera-peutic intervention of non-small cell lung cancer(NSCLC).Both in vitro and in vivo experimental models corroborate the inhibitory potency of β-elemene on NSCLCs.Our findings indicate that β-elemene fa-cilitates the maturation of miR-127-3p by inhibiting CBX8.Functioning as an upstream regulator of MAPK4,miR-127-3p deactivates the Akt/mTOR/p70S6K pathway by targeting MAPK4,thereby inducing autophagy in NSCLCs.Additionally,β-elemene augments the packaging of miR-127-3p into exosomes via SYNCRIP.Exosomal miR-127-3p further stimulates M1 polarization of macrophages by suppressing ZC3H4.Taken together,the detailed understanding of the mechanisms through which β-elemene in-duces autophagy in NSCLCs and facilitates M1 polarization of macrophages provides compelling scientific evidence supporting its potential utility in NSCLC treatment.
