Objective:To compare the outcomes of multiple scales, primarily the speech, spatial, and other qualities of hearing scale for parents（SSQ-P）, in children with ipsilateral vs. Contralateral cochleareimplantat ion（CRI）. Methods: A total of 69 children who received cochlear implantation surgery from April 1999 to June 2024 were included. Patients were divided into two groups based on whether the implantation was on the same side. General information such as gender, age, age at initial implantation and reimplantation was collected. The primary caregivers of the children were followed up by telephone using the categories of auditory performance（CAP）, speech intelligibility rating（SIR）, and SSQ-P questionnaires. Statistical methods including stepwise regression, linear regression, and permutation tests were employed to investigate if there were any statistically significant differences in the scores of CAP, SIR, SSQ-P total, SSQ-P speech perception, SSQ-P spatial hearing, and SSQ-P auditory quality dimensions between the ipsilateral and contralateral reimplantation groups. Results:Of the 69 children included, 62 were in the ipsilateral reimplantation group with a mean age of 11.1 years, and 7 were in the contralateral reimplantation group with a mean age of 11.7 years. Statistical analysis showed that patients in the contralateral reimplantation group had significantly lower SSQ-P total scores （P<0.05） and spatial hearing dimension scores （P<0.05） than those in the ipsilateral reimplantation group after controlling for the corresponding confounders. Conclusion:The effect of ipsilateral reimplantation of cochlear implants is superior to that of contralateral reimplantation in terms of overall auditory function and spatial hearing in daily life for children, but the mechanisms require further investigation.

Objective:To investigate the risk factors for new adjacent vertebral fracture after percutaneous kyphoplasty (PKP) in patients with osteoporotic vertebral compression fracture (OVCF) and their predictive efficacy.Methods:A retrospective cohort study was conducted to analyze the clinical data of 476 OVCF patients admitted to The Affiliated Wuxi People′s Hospital of Nanjing Medical University from January 2018 to December 2024, including 74 males and 402 females, aged 49-91 years [71(65, 79)years]. Among them, 397 patients underwent single-level PKP, while 79 received multi-level PKP. Surgical segments involved T 6 in 9 patients, T 7 in 9, T 8 in 14, T 9 in 12, T 10 in 9, T 11 in 50, T 12 in 110, L 1 in 173, L 2 in 77, L 3 in 46, L 4 in 31, and L 5 in 13. The patients were divided into adjacent vertebral fracture group ( n=55) and non-adjacent vertebral fracture group ( n=421) according to whether adjacent vertebral fracture was observed during the follow-up. The following data were collected in both groups: gender, age, body mass index (BMI), bone mineral density T-value, underlying diseases (hypertension, diabetes, coronary heart disease), prior cerebral infarction, history of OVCF, long-term glucocorticoid use, thoracolumbar fracture, number of operated vertebrae, cement injection approach (unilateral or bilateral), mean cement dose, postoperative vertebral height restoration rate, postoperative Cobb angle correction, postoperative thoracolumbar kyphosis angle correction, and cement distribution score. Univariate and multivariate Logistic stepwise regression analysis were performed to assess and identify independent risk factors for adjacent vertebral fracture in OVCF patients after PKP. Receiver operating characteristic (ROC) curve and area under the curve (AUC) were used to evaluate the risk factors′ predictive performance for adjacent vertebral fracture in OVCF patients after PKP. Results:Univariate analysis revealed significant differences in age, bone mineral density T-value, history of OVCF, long-term glucocorticoid use, number of operated vertebrae, and cement distribution score between the two groups ( P<0.05). The multivariate Logistic stepwise regression analysis showed that the bone mineral density T-value ( OR=0.68, 95% CI 0.48, 0.95, P<0.05) and cement distribution score ( OR=0.61, 95% CI 0.49, 0.76, P<0.01) were significantly correlated with new adjacent vertebral fractures after PKP. The ROC curve analysis showed that bone cement distribution score showed better predictive performance (AUC=0.72, 95% CI 0.64, 0.79), compared with bone mineral density T-value (AUC=0.62, 95% CI 0.54, 0.70), while the combined predictive performance of the two factors was the best (AUC=0.75, 95% CI 0.68, 0.81). Conclusions:Bone mineral density T-value and cement distribution score are independent risk factors for new adjacent vertebral fracture in OVCF patients after PKP. The predictive performance of cement distribution score is proved to be good and can be better in combination with bone mineral density T-value.

Aim To investigates whether sphingosine-1-phosphate(S1P)regulates the expression of mitochon-drial calcium uniporter(MCU)via the sphingosine-1-phosphate receptor/proline-rich tyrosine kinase 2(S1PR/Pyk2)sig-naling pathway,thereby reducing oxidative stress-induced mitochondrial damage and inhibiting mitochondria-related apopto-sis.Methods Human umbilical vein endothelial cells(HUVEC)were subjected to oxidative damage using hydrogen peroxide(H2O2)as a model.Different concentrations of S1P were applied to the oxidative damaged HUVEC.Addi-tionally,the S1PR1 agonist SEW2871,the S1PR1 inhibitor W146,and the Pyk2 inhibitor PF-562271 were used to explore the specific mechanism of S1P action.Results S1P treatment significantly alleviated oxidative damage in HUVEC and was accompanied by an increase in S1PR1 expression(P<0.05),while S1PR3 expression remained unchanged.Mean-while,the expression levels of Pyk2 and MCU decreased(P<0.05).SEW2871 further reduced mitochondrial damage,whereas W146 exacerbated it(P<0.05).Furthermore,the application of the Pyk2 inhibitor PF-562271 also reduced H2O2-induced mitochondrial damage(P<0.05),further confirming the role of Pyk2 in this process.Conclusion S1P reduces H2O2-induced mitochondrial damage and inhibits mitochondria-related apoptosis in HUVEC by suppressing Pyk2 expression via S1PR1.
