Objective: To explore the mediating effect of parental hostile attribution bias on depression and anxiety between parents and children, so as to provide the reference for the promotion of children's mental health. Methods: Students of grades 2-6 in two public primary schools in Linping District, Hangzhou City and their parents were investigated using stratified sampling method in November 2022. Emotions of children were surveyed using Depression Self-Rating Scale for Child (DSRSC) and Screen for Child Anxiety Related Emotional Disorders (SCARED), while emotions and hostile attribution bias of parents were surveyed using Self-rating Depression Scale (SDS), Self-rating Anxiety Scale (SAS) and Social Cognitive Screening Questionnaire (SCSQ). Mediating effect of parental hostile attribution bias on depression and anxiety between parents and children was analyzed using a structural equation model. Results: Totally 300 questionnaires were allocated, and 263 valid questionnaires were recovered, with an effective rate of 87.67%. There were 137 boys (52.09%), and 126 girls (47.91%), with a mean age of (9.95±1.44) years. There were 69 fathers and 194 mothers investigated. The prevalence of depression among parents was 27.00%, the prevalence of anxiety among parents was 4.18%, and the median score of hostile attribution bias was 1.00 (interquartile range, 2.00). The prevalence of depression among children was 11.03%, and the prevalence of anxiety among children was 29.66%. Parents' depression and anxiety affected children's depression and anxiety directly (effect value=0.270, 95%CI: 0.131-0.436), and also indirectly affected children's depression and anxiety by increasing their hostile attribution bias (effect value=0.028, 95%CI: 0.004-0.082), with the mediating effect contributed 9.40% of the total effect. Conclusion Parents' depression and anxiety affect children's depression and anxiety directly or indirectly through hostile attribution bias.

Objective To evaluate the diagnostic value of high frequency ultrasound in sebaceous gland carcinoma of eyelid (SC).Methods The ultrasonic characteristic for 11 cases with eyelid SC were respectively analyzed by using 13 MHz high frequency ultrasound and 22 MHz ultra-high frequency ultrasound.Results Through 13 MHz high frequency ultrasound,in 7 patients who exhibited Pagetoid invasion the lid shin thickness of tumor side displays no significant alteration in a comparison with normal side.Furthermore,the color Doppler flow imaging (CDFI) evealed a branch-like blood flow surrounding the masses in all cases,but the blood flow of seven patients with Pagetoid invasion had no difference compared with the healthy side.On 22 MHz ultra-high frequency ultrasound examination,slit-like low echo was found in 9 ;transition zone of tumor infiltration can be identified in 9 ; the echo of tumors with Pagetoid invasion was lower than the healthy side and the skin thickness of tumors with Pagetoid invasion was thicker (0.6 ±0.1) mm than the healthy side.CDFI revealed that mesh-basket like blood flow was rich in all patients,the small branch blood vessels arrived at subcutaneous,and vasa vasorum were found in some patients.The region with Pagetoid invasion was rich in blood flow.The sonography findings on 13 MHz and 22 MHz high frequency ultrasound examination were compared with chisquare test.There were significant differences on homogeneous echo,slit-like low echo,transition zone of tumor infiltration,infiltration skin thickness,blood distribution,central blood vessels,vasa vasorum,blood flow in the region with Pagetoid invasion (x2 =12.571,15.231,15.231,4.701,22.000,15.231,4.899,10.267,P＜0.05).Conclusions Slit-like low echo in the mass is a main finding of eyelid sebaceous gland cercinoma on the 22 MHz ultra-high frequency ultrasound.The ultra-high frequency ultrasound can accurately reveal the skin depth infiltrated by the eyelid sebaceous gland cercinoma and this method can provide solid guidance for clinical treatment strategies.

Objective To investigate the clinical value of the thickness of pharyngeal wall of nasopharynx in adenoids hypertrophy examined with CT. Methods CT manifestations in 117 patients suspected with adenoids hypertrophy were analysed. The thickness of adenoid and pharyngeal wall were observed. The width of adenoid/pharynx(A/N) ratio were measured and the correlation of pharyn-geal wails with A/N ratio were analysed. Results A/N ratio was ≥0.70 in 50 cases (group Ⅰ), between 0.60 ～ 0.70 in 35 cases (group Ⅱ) ,≤0.60 in 32 cases (group Ⅲ) ,the thickness of pharyngeal wall were (1.26±0.33) cm, (0.99±0.41) cm and (0.86± 0.19) cm respectively. There were significant differences between group Ⅰ and Ⅱ, Ⅲ in the thickness of pharyngeal wails(P<0.01). The relationship of linear regression of A/N ratio with pharyngeal wall was found and the equation of the thickness of pharyngeal wall was 1.69×A/N ratio-0.08. Conclusion There is correlation between A/N ratio and thickness of pharyngeal wall, which is helpful for clinical diagnosis of adenoid hypertrophy.
