Objective:To explore the correlations of sleep quality and architecture with heart rate variability (HRV) in patients with stenoses of vertebrobasilar artery system and internal carotid artery system.Methods:A retrospective study was performed; 72 patients with stenosis or occlusion of the head and neck arteries (not resulting in cerebral infarction) admitted to Department of Neurology, Second Affiliated Hospital of Zhengzhou University from June 2023 to June 2024 were chosen, including 33 patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system (VB group) and 39 patients with moderate-to-severe stenosis or occlusion of the internal carotid artery system (ICA group). Pittsburgh sleep quality index (PSQI) and polysomnography (PSG) were used to evaluate the sleep quality and architecture, respectively; and 24-hour ambulatory electrocardiogram was used to assess the HRV. Differences in PSQI score, PSG and HRV parameters between the two groups were compared; partial correlation analysis was used to explore the correlations of HRV parameters with PSQI scores and PSG parameters; multivariate linear regression was used to analyze the independent influencing factors for HRV.Results:(1) Compared with the ICA group, the VB group exhibited significantly higher PSQI scores, spontaneous arousal index (SAI), ratio of time of stage 1 non-rapid eye movement sleep/total sleep time (T N1/T t), and apnea-hypopnea index (AHI), while significantly lower ratio of time of rapid eye movement sleep/total sleep time (T R/T t), spindle wave density in stage 2 non-rapid eye movement sleep (N2), lowest blood oxygen saturation, standard deviation of normal to normal intervals (SDNN) of all sinus beats, low-frequency power (LF), and high-frequency power (HF, P<0.05). (2) In both VB group and ICA group, SDNN was negatively correlated with PSQI score ( r=-0.461, P=0.020; r=-0.378, P=0.036). In the VB group, SDNN was negatively correlated with T N1/T t ( r=-0.467, P=0.019) and SAI ( r=-0.551, P=0.004), and positively correlated with ratio of time of stage 3 non-rapid eye movement sleep/total sleep time (T N3/T t, r=0.686, P<0.001) and spindle wave density in N2 ( r=0.518, P=0.008); LF and HF were negatively correlated with SAI ( r=-0.481, P=0.015; r=-0.564, P=0.003). In the ICA group, HF was negatively correlated with spindle wave density in N2 ( r=-0.369; P=0.041). (3) Multivariate linear regression results indicated that T N3/T t (β=0.348, P=0.018), SAI (β=-0.330, P=0.018), and spindle wave density in N2 (β=0.286, P=0.013) were independent influencing factors for Ln_SDNN in patients with moderate-to-severe stenosis or occlusion of the vertebrobasilar system. Conclusion:Patients with stenosis or occlusion of the vertebrobasilar system exhibit poorer subjective sleep quality, increased light sleep, heightened arousal, and reduced sleep stability compared with those with stenosis or occlusion of the internal carotid artery system, which may be caused by the imbalance of autonomic nerve function.

Objective To investigate the differences of language abilities between children with developmental delay(DD)and those with autism spectrum disorder(ASD)aged 3-6 years,and to provide references for clinical differential diagnosis and subsequent rehabilitation therapy.Methods In this study,61 cases of DD children and 61 cases of ASD chil-dren were selected.The language ability of children was assessed using the"Children's Language Ability Assessment Stand-ards and Methods",which evaluated grammar,comprehension,expression and communication abilities.Results Children with DD showed better comprehension and social skills but weaker grammar and expressive abilities.Children with ASD generally had lower levels in all language areas.There was no significant difference in the average language ability or expres-sive ability the two groups(P＞0.05),but the language comprehension ability and communication ability of the ASD group were significantly lower than those of the DD group(P＜0.05).The grammar ability of the ASD group was higher than that of the DD group(P＜0.05).Conclusion The levels of different language areas of children with DD and ASD children are significantly different.Language ability tests can assist in the differential diagnosis of DD and ASD children,and provide reference for language rehabilitation training.

Objective:To investigate the correlation between computed tomography (CT) findings and serum micrornA-497 (miR-497), carbohydrate polypeptide antigen 24-2 (CA24-2) and hepatitis B surface antigen (HBsAg) expression in patients with colorectal cancer (CRC).Methods:A total of 64 CRC patients admitted to the Jiangsu Cancer Hospital from January 2021 to December 2022 were prospectively selected, and the surgical pathological results were used as the gold standard. Preoperative CT examination and serum miR-497, CA24-2 and HBsAg levels were performed in all patients. The CT images of the patients were analyzed. Pearson correlation analysis was used to evaluate the correlation between CT findings and serum miR-497, CA24-2 and HBsAg expression levels in CRC patients.Results:The CT imaging features of CRC patients were as follows: The intestinal wall was semi-annular in 37.50%(24/64), annular in 32.81%(21/64), localized thickening in 29.69%(19/64), the intestinal lumen was irregular and narrow, and most of the periintestinal fat was blurred in 59.38%(38/64). 67.19%(43/64) showed uneven enhancement, 51.56%(33/64) had lymph node metastasis and 43.75%(28/64) had liver metastasis. Lymph node metastasis in CRC patients was correlated with serum miR-497 and CA24-2 levels (all P<0.05), but not with serum HBsAg levels ( P>0.05). Liver metastasis in CRC patients was associated with serum HBsAg expression ( P<0.05), but not with serum miR-497 and CA24-2 levels (all P>0.05). Other CT findings of CRC patients were not correlated with serum miR-497, CA24-2 and HBsAg levels (all P>0.05). Pearson correlation analysis showed that lymph node metastasis in CRC patients was negatively correlated with the expression level of serum miR-497 ( r=-0.491, P<0.05), while positively correlated with the expression level of serum CA24-2 ( r=0.506, P<0.05). There was no correlation with serum HBsAg expression level ( P>0.05). The occurrence of liver metastasis in CRC patients was negatively correlated with the expression level of serum HBsAg ( r=-0.529, P<0.05), but was not correlated with the expression levels of serum miR-497 and CA24-2 (all P>0.05). Conclusions:CT imaging findings can evaluate the biological behavior of tumor cells in CRC patients to a certain extent, and have a certain correlation with the expression levels of serum miR-497, CA24-2 and HBsAg, which can reflect the lymph node and liver metastasis of tumors, and provide a basis for clinical comprehensive treatment and prognosis prediction of patients.

Objective To explore the social-emotional competence of hearing-impaired children and its related factors. Methods A questionnaire was used to investigate the social-emotional competence, hearing status, temperament and parenting style of 68 hearing-impaired children. Results and Conclusion The social-emotional problems of hearing-impaired children were prominent, especially in the dimension of externalizing behavior (13.23%) and competence (10.29%). The girls had more implicit behavior problems than the boys (P<0.05). Aided thresholds, children's temperament and parenting style had significant influence on social-emotional competence of hearing-impaired children (P<0.05).

Objective To explore the reliability and validity of Meadow-Kendall Social-Emotional Assessment Inventory (SEAI) for Deaf and Hearing-Impaired Students Preschool Version in China. Methods 96 hearing-impaired children were assessed with SEAI, and 30 of them were assessed with Conners Teacher Rating Scale (TRS), 30 by another teacher, 30 by the first teacher 2 weeks later. The data were analyzed with Pearson's or Spearman's correlation analysis. Results For sociable communicative behaviors, impulsive dominating behaviors, developmental lags, anxious compulsive behaviors, items related to deafness, test-retest reliability (correlated coefficient, r) was 0.94,0.55, 0.87, 0.31, 0.74; and Cronbach's α was 0.70, 0.76, 0.76, 0.80, 0.68. The inter-rater reliability was 0.90, 0.58, 0.46, 0.14, 0.55. The subscales of SEAI were correlated (r=-0.36~-0.89, P<0.05) with the subscales of TRS. Confirmatory factor analysis showed that the subscale model of SEAI was reasonable. Conclusion The SEAI for Deaf and Hearing-impaired Students Preschool Version can be used for Chinese hearing-impaired children.
