Objective: To explore impacts of sports games designed based on the information-motivation-behavioral skills model (IMB) on prosocial behavior in children with intellectual and developmental disabilities (IDD) attending regular classes, so as to provide a theoretical basis for promoting the development of prosocial behavior in school age IDD children. Methods: From February to March 2023, 40 children with intellectual disabilities aged 8-9 who were enrolled in ordinary schools in Beijing were recruited by using WeChat parents to send messages. They were randomly divided into an experimental group (19 before intervention, 17 after intervention) and a control group (19 before intervention, 19 after intervention) by lottery method. During the study period, children in both groups received the same frequency and quality of regular physical activities. The experimental group, in addition, underwent a 13 week sports game intervention based on the IMB model, 4 times a week, each session lasting 50 minutes. The sports game intervention scheme based on IMB model was divided into two modules,including basic training and development training:low difficulty sports game intervention based on emotion recognition, and medium low difficulty and medium difficulty sports game intervention based on social training such as "prosocial". The Griffith Empathy Measure (GEM) and the Prosocial Behavior Scale for Adolescents (PBSA) were used to assess empathy ability and prosocial behavior levels of children in both groups before and after the intervention. Results: After intervention, the cognitive empathy dimension, emotional empathy dimension and total score of GEM in the experimental group (39.15±2.85, 38.54±1.94, 77.69±3.95) were higher than control group (32.18±4.18, 32.28± 4.28, 64.56±6.48) and before intervention (33.92±4.94, 31.30±4.61, 65.23±8.47), and the differences were statistically significant ( F =12.06, 6.99, 14.90; 8.95, 7.36, 13.22, P <0.05). After intervention, compliance with public welfare factors, trait factors and total score (31.33±1.97, 16.67±1.03, 71.83±2.93) were higher than control group (22.65±1.58, 12.59±0.71, 59.47± 2.18 ) and before intervention (22.00±1.27, 12.17±0.75, 58.00±1.67), and the differences were statistically significant ( F = 17.00 , 36.54, 12.71; 29.87, 13.09, 13.12, P <0.05). Conclusion Sports game intervention based on IMB model can effectively promote the development of prosocial behavior of children with IDD attending regular classes.

Objective:To explore the diagnostic value of the nomogram constructed based on multi-modal ultrasound features combined with inflammatory complex indicators for benign and malignant nodules in breast imaging reporting and data system (BI-RADS) .Methods:102 female patients with breast BI-RADS type 4 nodules who were treated in Northwest Women’s and Children’s Hospital from Jan. 2021 to Mar. 2024 were included as study objects, and benign and malignant nodules were determined according to postoperative pathological examination results. Conventional ultrasound, shear-wave elastography and contrax-ultrasound were performed in each breast BI-RADS patient with Class 4 nodules using Mindray resona7 ultrasonic diagnostic instrument within 1 week before surgery to record the ultrasonic characteristics. According to the results of laboratory examination, neutrophil to lymphocyte ratio (NLR) and platelet to lymphocyte ratio (NLR), PLR, the systemic immune inflammation index (SII), and the systemic inflammatory response index (SIRI) were calculated and recorded.Results:There were 42 cases of malignant nodules and 60 cases of benign nodules. Compared with the benign group, there were significant differences in nodule boundary, internal echo, Alder blood flow grading, hard ring sign, area expansion after enhancement, peripheral radial enhancement and perfusion defect in the malignant group ( χ2 value was 5.83, 9.31, 5.20, 10.25, 6.99, 7.24, 4.90, P < 0.05). Compared with the benign group, NLR and SIRI in the malignant group were significantly increased, with statistical difference (t-value 3.13 and 4.33, P < 0.05). The results of multi-factor Logistics regression analysis show that breast BI-RADS were characterized by blurred nodule boundary (X1), Alder blood flow grade 2-3 (X3), hard ring sign (X4), enlarged area after enhancement (X5), peripheral radial enhancement (X6), NLR≥2.29 (X8), SIRI≥0.91 (X9) were independent risk factors for malignant nodules ( P < 0.05). Based on these factors, the Logistics regression model was established as Logit (P) = -3.217 + 0.291X1 + 1.051X3 + 0.354X4 + 0.360X5 + 0.524X6 + 0.513X8 + 0.726X9. The results of calibration curve and clinical decision curve evaluation showed that the model had good accuracy and high predictive value. ROC curve analysis results showed that the area under the curve of the nomogram model for predicting benign and malignant nodules of category 4 breast BI-RADS was 0.925 (0.877-0.974), the sensitivity was 88.6%, and the specificity was 86.1%. Conclusion:The nomogram model constructed by multi-modal ultrasound combined with inflammatory complex index NLR and SIRI has certain application value in the differential diagnosis of benign and malignant breast BI-RADS 4 nodules.

At present, ultrasound, CT, and MRI are the main radiological examination methods for HAE, with certain limitations in preoperative diagnosis and evaluation. This article introduces the guiding effect of three-dimensional visualization technique and its derivative technologies in the accurate diagnosis and preoperative evaluation of HAE, so as to provide help for the clinical diagnosis and treatment of HAE in the future.

Objective: To develop a method for generating three-dimensional (3D) digital models of the periodontal ligament (PDL) using 3D cone-beam computed tomography (CBCT) reconstruction and to evaluate the accuracy and agreement of the 3D PDL models in the measurement of periodontal bone loss. Methods: CBCT data collected from four patients with skeletal Class III malocclusion prior to periodontal surgery were reconstructed at three voxel sizes (0.2 mm, 0.25 mm, and 0.3 mm), and 3D tooth and alveolar bone models were generated to obtain digital PDL models for the maxillary and mandibular anterior teeth. Linear measurements of the alveolar bone crest obtained during periodontal surgery were compared with the digital measurements for assessment of the accuracy of the digital models. The agreement and reliability of the digital PDL models were analyzed using intra- and interexaminer correlation coefficients and Bland–Altman plots. Results: Digital models of the maxillary and mandibular anterior teeth, PDL, and alveolar bone of the four patients were successfully established. Relative to the intraoperative measurements, linear measurements obtained from the 3D digital models were accurate, and there were no significant differences among different voxel sizes at different sites. High diagnostic coincidence rates were found for the maxillary anterior teeth. The digital models showed high intra- and interexaminer agreement. Conclusions Digital PDL models generated by 3D CBCT reconstruction can provide accurate and useful information regarding the alveolar crest morphology and facilitate reproducible measurements. This could assist clinicians in the evaluation of periodontal prognosis and establishment of an appropriate orthodontic treatment plan.

AIM: To explore schisandrin B (Sch B) pretreatment reduces intestinal ischemia reperfusion injury (IIRI) through inhibiting apoptosis by activation of Nrf2/HO-1 signing pathway in mice by network pharmacology and in vivo experiment. METHODS: (1) The targets of Sch B and IIRI were searched from online databases, Drawing Venn diagram to obtain the common target of them. Cytoscape software was imported to construct the protein-protein interaction (PPI) network to establish the "Drugs-Disease-core target gene" network. The mechanism of Sch B against IIRI was predicted through GO and KEGG enrichment analysis. (2) Thirty-six C57BL/6J mice were randomly divided into six groups (n = 6). The model of IIRI was established in four groups except the sham operation group. Three of the groups were pretreated with Sch B, Nrf2 inhibitor ML385, and Sch B + ML385, respectively. After the experiment, intestinal tissue samples were taken for HE staining, Chiu ' s score, apoptosis staining, immunohistochemistry (IHC), and immunoblotting (Western blot). RESULTS: A total of 412 Sch B related tar- gets, 2 166 IIRI related targets and 153 common targets were screened out through network pharmacology. There were 88 "Sch B-IIRI-core target gene" included NFE2L2 (Nrf2), HMOX1 (HO-1), BCL2, CASP3 (caspase 3), and so on. KEGG enrichment analysis screened 163 related pathways, apoptosis pathway ranked high showing that the pathway may play a key role in the treatment of IIRI by Sch B. The animal experiment had shown that Sch B reduced the Chiu's score and apoptotic while upregulating Nrf2, HO-1, Bcl-2 protein expression levels and Bcl-2/Bax, downregulating Bax, and cleaved caspase-3 expression levels, thereby reducing IIRI in mice, and that Nrf2 inhibitor ML385 reversed this process (P < 0.05). CONCLUSION: This study reveals that Sch B has the characteristics of multi-target and multi-pathway in the reduction of IIRI, and Sch B can reduce IIRI through inhibiting apoptosis by activation of Nrf2/ HO-1 pathway.

AIM: To verify the role of tetramethylpyrazine (TMP) in intestinal ischemia-reperfusion (I/ R) injury and its relationship with pyroptosis. METHODS: Thirty-six healthy SPF male C57BL / 6 mice, 8-12 weeks old, weighing 20-25 g, were divided into six groups randomized by table of random number (n = 6/group): Sham group (S1 group)Ischemia/reperfusion group (I/R1 group), I/R + TMP treatment group: 15 mg/kg (T15 group), 30 mg/kg (T30 group), 60 mg/kg (T60-1 group), 120 mg/kg (T120 group). In experiment 2, thirty healthy SPF male C57BL/6 mice were divided into five groups (n = 6/group): Sham group (S2 group), I/R group (I/ R2 group), I/R + dimethyl sulphoxide (DMSO) group (DMSO group), I/R + TMP (60 mg/kg) group (T60-2 group), and I/R + DMSO + TMP (60 mg/kg) + Nigericin sodium salt (NSS) group (T60+NSS group). I/R-induced intestinal injury was established by clamping the superior mesenteric artery for 45 minutes, followed by 120 minutes of reperfusion, while the sham group mice underwent isolation of superior mesenteric artery without clamping. An NLRP3 agonist NSS was dissolved in DMSO, was intraperitoneally injected (4 mg/kg) 60 minutes before ischemia. And DMSO group mice were intraperitoneally administered with corresponding DMSO. Different TMP dosage groups and T60+NSS group mice were intraperitoneally administered with TMP 30 minutes before ischemia. IL-1β and IL-18 concentrations in the intestine were measured at 120 minutes after reperfusion by ELISA. The pathological changes of the sections were observed by optical microscope, and the intestinal mucosal injury was evaluated by Chiu's score grading. Western blot was used to detect NLRP3, Caspase-1, and GSDMD in intestinal tissue. RESULTS: Statistically significant increase of Chiu's score, IL-1β, IL-18 concentrations in the I/R1 group were found as compared with S1 group (P<0.05). And compared with I / R1 group, Chiu's score and IL-1β, IL-18 concentrations in the T60-1, T120 groups were reduced (P<0.05). Moreover, Chiu's score in the T120 group was lower than that in the T60 group (P<0.05). We found a statistically significant increase of Chiu's score and IL-1β, IL-18 concentrations and the expression of NLRP3, GSDMD, caspase-1 in the I/R group (P<0.05) as compared with S2 group. Compared with I / R2 group, Chiu's score, IL-1β, IL-18 concentrations and NLRP3, GSDMD, caspase-1 expression in the T60-2 group was reduced (P<0.05). Compared with T60-2 group, Chiu's score, IL-1β, IL-18 concentrations and NLRP3, GSDMD, caspase-1 expression in the T60 + NSS group were upregulated (P<0.05). CONCLUSION: The protective effect of TMP against intestinal I / R injury was dose-dependent. And TMP can decrease pyroptosis mainly by inhibiting the activation of the NLRP3 inflammasome.
