Objective To compare the results of TEOAE and DPOAE in the same population of normal newborns, to provide information on choosing appropriate screening tools.Methods A two-steps protocol was taken with the first screening during the first 48 to 72 hours of birth and rescreened from one to two months old if the newborns failed the first screening.For each step of screening, TEOAE and DPOAE were performed simultaneously using AccuScreen hearing screening instrument (Madsen-GN Otometrics, Taastrup, Denmark).A total of 1 062 normal newborns (F/M=508/554) delivered in Peking Union Medical College Hospital were enrolled in this research for the first screening.Infants who failed either TEOAE or DPOAE screening in the first screening were referred to a second screening.Among them, 135 performed both DPOAE and TEOAE in the second step.The newborns who failed the second screening would receive ABR when they were 3 months old.Results In the first screening,the failure rate for TEOAE was 11.0% (117/1 062) and 13.7% (145/1 062) for DPOAE.In the second screening step, the failure rates were 17.8% (24/135) and 20.7% (28/135) for TEOAE and DPOAE, respectively.Chi-square and Fisher's test showed that the failure rates of DPOAE were significant higher than TEOAE for both steps (P<0.001).The agreements between TEOAE and DPOAE were 96.0% and 95.6% for the first and second steps respectively, and the kappa values were 0.817 and 0.857.As to the average time taken to accomplish the screening for one ear, TEOAE was 24±25 s and DPOAE was 40±34 s during the first screening;in the rescreening, TEOAE was 52±41 s and DPOAE was 73±62 s.Paired-t tests showed that the differences between DPOAE and TEOAE testing time were statistically significant (P=0.000) in both screening steps.Finally, 7 newborns (10 ears) were diagnosed conductive hearing loss(except 1 ear was sensorineural hearing loss).Conclusion As a screening tool, TEOAE got lower refer rates and took less time than DPOAE implicating TEOAE a better screening tool for normal neonates.

Objective:To test the psychometric properties of the super brief-pathological narcissism inventory(SB-PNI) in Chinese college students.Methods:A total of 541 college students were recruited through convenient sampling method.All subjects were measured by SB-PNI, fear of missing out scale(FOMOs), Interpersonal Communication Scale and Social Interaction Scale.SPSS 25.0 was used for item analysis, criterion related validity analysis and Cronbach α coefficient. Mplus 7.4 software was used for structural validity analysis.Results:Through the construct validity analysis, it was found that the Bi-factor model was well fitted.SB-PNI presented a better Bi-factor structure(χ 2/ df=2.03, CFI =0.96, TLI=0.94, RMSEA=0.04, SRMR=0.04), namely a general factor and two local factors (grandiose narcissism and vulnerable narcissism). The score of SB-PNI was positively correlated with grandiose narcissism, vulnerable narcissism, interpersonal communication, social interaction and fear of missing out ( r=0.13-0.85, all P<0.01). The Cronbach's α coefficients of SB-PNI degreed from 0.74 to 0.81.The composite reliability of SB-PNI degreed from 0.75 to 0.84.The retest reliability of SB-PNI degreed from 0.75 to 0.85.The homogeneity reliability of SB-PNI was 0.64. Conclusion:The Chinese version of the SB-PNI has good validity and reliability among Chinese college students.

Objective:To analyze the diagnosis, treatment and prognosis of patients with rare malignant tumors of the temporal bone. Methods:Four cases of rare temporal bone malignant tumors in our hospital between March 2014 and December 2020 were reviewed, including two cases of chondrosarcoma, one case of fibrosarcoma and one case of endolymphatic cystic papillary adenocarcinoma. There were three males and one female, ages between 28 and 56 years at the time of surgery. Common symptoms included hearing loss, facioplegia, tinnitus, and headache. All patients underwent imaging examinations to evaluate the extent of the lesions. Tumors were removed by subtotal temporal bone resection or infratemporal fossa approach, and postoperative adjuvant radiotherapy was applied if necessary. Results:One of the two chondrosarcoma patients was cured by complete resection of the tumor for 75 months, the other one recurred after the first excision of the tumor and underwent infratemporal fossa approach resection of skull base mass again with no recurrence found yet for 112 months. One patient with fibrosarcoma survived for 28 months after surgery with a positive margin and post-operative radiotherapy. One patient with endolymphatic cystic papillary adenocarcinoma recurred 12 months after subtotal lithotomy, and underwent subtotal temporal bone resection again, combined with radiotherapy. No recurrence was found for 63 months. Conclusion:The incidence of rare temporal bone malignant tumors is extremely low, the location is hidden, and the symptoms are atypical. Attention should be paid for early detection and early treatment. Surgical resection is the main treatment, and radiotherapy can be supplemented in the advanced stage or with a positive margin.

Objective:To establish the first Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale in China and evaluate its preliminary application value in the standardized training for radiation oncology resident physicians.Methods:Based on the educational curriculum and examination requirements for the standardized training for radiation oncology resident physicians, as well as the standardized Mini-Clinical Evaluation Exercise (Mini-CEX) scale commonly used in clinical practice, the Mini-Formative Evaluation of Radiation Oncology (Mini-FERO) scale was developed to facilitate the standardized training for resident physicians in the field of radiation oncology. In this prospective study, a randomization method using a random number table was employed to select a cohort of 26 resident physicians who completed their rotations in Department of Radiation Oncology at the Cancer Hospital, Chinese Academy of Medical Sciences from March 1, 2021 to December 31, 2021. The Mini-FERO scale was administered in the initial, middle, and final stages during the rotation period. The differences in evaluation scores before and after the assessments were analyzed by paired t-test. Furthermore, participating resident physicians and supervising teachers provided satisfaction ratings, and a comprehensive evaluation of the Mini-FERO scale was conducted. Results:The average scores of the three examinations of 26 resident physicians demonstrated a successive improvement, with individual performance in each assessed category also showing progressive enhancement. The second evaluation exhibited a more pronounced score increase compared to the first evaluation, with a mean improvement of (1.43±1.02) points ( t=7.13, P<0.001); while the third evaluation had a mean improvement of (0.41±0.50) points ( t=4.07, P<0.001) compaired to the second evaluation, with a mean difference of (1.02±1.15) points between the two ( t=4.53, P<0.001). The average time required for the assessments was (34.31±24.46) min. Overall satisfaction ratings from the evaluated resident physicians for the Mini-FERO scale were (8.42±0.85) points, and supervising teachers reported an overall satisfaction rating of (8.45±0.85) points. The satisfaction rate was 96% (25/26). Conclusions:In this study, the Mini-FERO scale was successfully developed and validated in the context of clinical teaching practice for radiation oncology resident physicians. The Mini-FERO scale is proven to be a feasible tool for assessing the gradual improvement of resident physicians throughout their learning process in the field of radiation oncology. Importantly, it offers the advantages of short assessment time, thereby avoiding additional burden on supervising teachers. The adoption of the Mini-FERO scale addresses current limitations of lacking of formative evaluation in the standardized training for radiation oncology resident physicians.
