Objective:To investigate the role of adenosine triphosphatase phospholipid transporter 10a(ATP10a)methylation assay in the triage of atypical squamous cell of undetermined significance(ASC-US)and low-grade squamous intraepithelial lesions(LSIL)in cervical cytology.Methods:188 patients with cervical exfolia-ted cells of ASC-US and LSIL were selected,and High-risk human papilloma virus(HR-HPV)typing and cervical biopsy results of the patients were collected at the same time.The cervical biopsy pathology results were used as the gold standard,and they were divided into inflammation,LSIL,high grade squamous intraepithelial lesions(HSIL)and cervical squamous cell carcinoma(SCC).Classify inflammation and LSIL as LSIL-group,HSIL and SCC as HSIL+group to compare the efficacy of ATP10a methylation and HR-HPV testing for diagnosis of HSIL+in this population(including HSIL and SCC).Results:The methylation detection value of ATP10a in the inflam-mation,LSIL,HSIL,and SCC patients were 19.035(16.478,20.823),13.446(5.890,20.674),10.336(4.733,17.336),4.223(1.713,7.754),respectively.The methylation detection value of ATP10a in the LSIL-group was 17.812(10.787,20.686),while that in the HSIL+group was 7.251(3.170,14.194).There was a statistically sig-nificant difference between the groups(Z=-5.824,P＜0.001).The proportion of HR-HPV positivity in the LSIL-group was 70.9％,which was lower than that of the HSIL+group(88.2％),and the difference was statistically significant(Z=-2.887,P=0.004).The specificity,negative predictive value(NPV),and area under the receiver operating characteristic(ROC)curve(AUC)of ATP10A methylation diagnosis of HSIL+(66.0％,79.1％,and 0.747)were higher than those of HR-HPV detection(29.1％,50.7％,0.587).Sensitivity and positive predictive value(PPV)(78.8％and 65.7％)were lower than those of HR-HPV testing(88.2％and 75.0％).when using ATP10a methylation instead of HR-HPV detection for triage of cytological abnormalities(ASC-US,LSIL),the col-poscopy referral rate could be reduced to 54.3％.In the ASC-US population,the AUC(0.683)for the diagnosis of HSIL+by ATP10a methylation test was higher than that of HR-HPV test(0.599),and the difference was statisti-cally significant(P=0.028).In the LSIL population,the AUC(0.828)for the diagnosis of HSIL+by ATP10a methylation test was still higher than that of HR-HPV test(0.563),and the difference was statistically significant(P=0.005).Conclusions:ATP10a methylation levels increased with the severity of cervical lesions,and the di-agnostic efficacy of ATP10a methylation detection for the severity of cervical lesions may not be lower than HR-HPV typing.

Objective To establish the judgment basis of ventilation pipe status by 0 daPa wideband acoustic immittance(WAI-0 daPa),and to assist doctors to determine the status of ventilation tube and determine the timing of extubation.Methods A total of 43 children with 62 ears aged 3-6 years old were tested by 0 daPa broadband acoustic reactance test.The normal middle ear function group were ten children with 20 ears.Children with secreto-ry otitis media more than 12 months after tympanic tube catheterization were divided into 11 cases 19 ears of clear ventilation tube group,and 23 ears in 22 cases of ventilation tube blockage group.A total of 107 frequencies of WAI-0 daPa were obtained.The Kruskal-Wallis H and Nemenyi were used to analyze the influence of ventilation tube status on WAI-0 daPa.Results The WAI-0 daPa at 226-667 Hz was significantly higher in the clear ventila-tion tubegroupthan in the normal middle ear group.The WAI-0 daPa at 226-500 Hz was significantly lower in the blocked ventilation tube group than in the clear ventilation tube group.The WAI-0 daPa at 2 000-3 364 Hz and 6 727 Hz in the normal middle ear function group were significantly higher than those in the blocked ventilation tube group.The WAI-0 daPa in low frequencies was less than 20％,the possibility of blackage of eardrum tube was greater.Conclusion The absorptivity in low frequency region of WAI-0 daPa can be used to determine the status of tympanic catheter ventilation tube and assist doctors to determine the timing of extubation.

Objective To investigate the feasibility of estimating the real-ear-to-coupler difference(RECD)in children with head circumference,so as to further optimize the personalized and accurate matching scheme of hearing aid fitting for children.Methods A total of 106 children(197 ears)were enrolled in this study.Head circumference was measured using a soft ruler and RECD was measured using OmetroricsAuricalTM.SPSS software was used to analyze the correlation between the head circumference,month age and RECD values at each frequency of children.Results ① The head circumference of boys was slightly larger than that of girls,but there was no significant differ-ence between them(P＞0.05).② Unitary linear correlation analysis showed that RECD values at 750-6 000 Hz were negatively correlated with the head circumference,and a regression equation was established between RECD values at 1 000-6 000 Hz and the head circumference.③ RECD values calculated by regression formula based on the head circumference showed no significant difference between 1 000-3 000 Hz and 6 000 Hz and children's actu-al RECD values.Conclusion The individual RECD values of 0-6 years old children were correlated with the head circumference,and with the increase of the head circumference,RECD values at middle and high frequencies de-creased gradually.For children whose physical developments were not consistent with biological age,the RECD data at middle and high frequencies could be estimated based on the head circumference.

Objective:This study aimed to compare the audiological characteristics between children with unilateral auditory neuropathy (UAN) and single-sided deafness (SSD) to establish a valid basis for the differential diagnosis of children with UAN.Methods:A retrospective analysis was conducted on audiological and imaging evaluations of children with UAN and SSD who were treated at Beijing Children′s Hospital of Capital Medical University between May 2015 and June 2023. There were 17 children with UAN, comprising 10 males and 7 females, with an average age of 4.7 years. Additionally, there were 43 children with SSD, consisting of 27 males and 16 females, with an average age of 6.5 years. Audiological assessments included Auditory brainstem response (ABR), Steady-state auditory evoked potential (ASSR), Behavioural audiometry, Cochlear microphonic potential (CM), Distortino-product otoacoustic emission (DPOAE), and acoustic immittance test. The results of the audiological assessment and imaging phenotypic between the two groups of children were compared and analyzed by applying SPSS 27.0 statistical software.Results:(1) The UAN group (77.8%) had a significantly higher rate of ABR wave III L than the SSD group (20.9%) ( P<0.01). The PA thresholds at 500 Hz and 1 000 Hz of children with SSD were higher than those of children with UAN, while the ASSR thresholds at 500 Hz, 1000 Hz, 2 000 Hz, and 4 000 Hz of children with SSD were significantly higher than those of children with UAN ( P<0.05). (2) The degree of hearing loss in both UAN and SSD children was predominantly complete hearing loss. The percentage of complete hearing loss was significantly higher (χ2=4.353, P=0.037) in the SSD group (93.0%, 40/43) than in the UAN group (63.6%, 7/11). However, the percentage of profound hearing loss was significantly higher in the UAN group (27.3%, 3/11) than in the SSD group (2.3%, 1/43) ( Fisher′s exact test, P=0.023). In terms of hearing curve configuration, the percentage of flat type was significantly higher in the SSD group (76.7%, 33/43) than in the UAN group (36.4%, 4/11). The proportion of the UAN group (27.3%, 3/11) was significantly higher than that in the SSD group (2.3%, 1/43) in ascending type ( P<0.05). There were no statistically significant differences in the hearing curves of the declining type and other types between the two groups ( P>0.05). (3) The proportion of imaging assessment without abnormality was significantly more common in the UAN group (81.8%) than in the SSD group (37.1%) (χ2=6.695, P=0.015). Conclusions:Compared to children with SSD, the occurrence of wave III L on the ABR test was significantly more common in children with UAN. The percentage of ascending hearing curves was significantly higher in children with UAN than in children with SSD. ASSR thresholds were significantly lower in children with UAN. The normal imaging phenotype was significantly more common in children with UAN than in children with SSD.

Objective To investigate the effect of auditory brainstem response(ABR)in clinical detection and severity assessment of autism spectrum disorder(ASD)in children with normal hearing.Methods ① A total of 55 autistic children(110 ears)with normal hearing and 55 children(110 ears)with typical development(TD)who did not differ in sex composition ratio and average monthly age were divided into four sub-groups according to age:≤24 months group(22 ears),25～36 months group(40 ears),37～48 months group(28 ears)and＞48 months group(20 ears).The ABR latencies and interpeak latencies were compared between ASD children and age-matched TD children.② ASD children were graded by severity according to the Diagnostic and Statistical Manual of Mental Dis-orders(DSM-V),and the correlations between the ABR latencies and interpeak latencies in autistic children with normal hearing and the severity grading were studied.Results ① No statistically significant differences in ABR wave latencies and interpeak latencies were found in autistic children with normal hearing under 24 months of age compared to age-matched TD children(P＞0.05).② Compared with children with TD,autistic children with nor-mal hearing at 25～36 months of age had significantly longer wave Ⅲ latencies and the interpeak latencies of Ⅰ-Ⅲ andⅠ-Ⅴ;the significantly longer wave Ⅲ,Ⅴ latencies,the interpeak latencies of Ⅰ-Ⅲ,Ⅲ-Ⅴ and Ⅰ-Ⅴ in autistic chil-dren with normal hearing at 37～48 months of age.Autistic children with normal hearing in the＞48 months group had significantly longer wave Ⅴ latencies and interpeak latencies of Ⅲ-Ⅴ,Ⅰ-Ⅴ than age-matched TD children(P＜0.05).③ The higher the ASD severity grading the longer the wave Ⅲ and V latencies and the longer interpeak latencies of Ⅰ-Ⅲ,Ⅲ-Ⅴ,and Ⅰ-Ⅴ(P＜0.05).Conclusion Differences in the level of auditory brainstem pathway de-velopment emerged at 25 months of age,and autistic children with normal hearing had significantly lower levels of auditory brainstem development than age-matched TD children.There were correlations between the latencies and interpeak latencies of ABR in autistic children with normal hearing and the severity grading.
