Objective:To construct a maintenance model of ophthalmic equipment of hospital based on Delphi method,so as to provide a new idea in management for ophthalmic equipment.Methods:The maintenance evaluation system of ophthalmic equipment was constructed by Delphi method,and the analytic hierarchy process(AHP)was applied to determine weight of evaluation index of equipment so as to standardize the management for ophthalmic equipment.A total of thirty used equipment that related to diagnosis and treatment for eye disease in Eye Hospital of China Academy of Chinese Medical Sciences from January 2022 to January 2023 were selected.According to different management modes,the conventional management mode(15 equipment)and Delphi method management mode(15 devices)were adopted respectively to manage equipment.A self-made questionnaire was adopted to investigate the satisfaction degree of medical staffs of the department of ophthalmology,and staffs of purchasing equipment for clinical configuration and use of ophthalmic equipment.The standardization degree of operation management for ophthalmic equipment,operation quality of equipment and satisfaction of medical staffs for clinical configuration of the two management modes were compared.Results:The scores of standardization degree of operation,disinfection and sterilization,maintenance and fault repair were respectively(92.14±5.36),(90.56±6.23),(91.98±5.65)and(92.16±6.36)after the Delphi method were adopted,which were higher than these of conventional management mode,and the differences of them were statistically significant(t=14.809,14.627,16.126,14.872,P<0.05).The average"power on"rate,operation rate,pass rate of acceptance and growth amplitude of cost-benefit of ophthalmic equipment were respectively(90.23±2.05)%,(96.36±3.98)%and(7.66±1.69)%after management with Delphi method was adopted,all of which were higher than these of conventional management mode,and the differences of them were statistically significant(t=9.649,4.248,8.479,16.867,P<0.05).The satisfaction rates of medical staffs of ophthalmic department and staffs of purchasing equipment for the rationality of clinical allocation process,standardization of system and effectiveness of quality of ophthalmic department of adopting Delphi method management mode were respectively 93.33%,93.33%and 90%,all of which were higher than those of conventional management mode,and the differences were statistically significant(x2=7.952,6.667,7.200,P<0.05).Conclusion:The application of the maintenance model of ophthalmic equipment of hospital based on Delphi method can enhance the qualities of managing and operating equipment,and improve the service level of equipment in management for ophthalmic equipment.

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.

Background: Maturity-onset diabetes of the young (MODY) due to variants of hepatocyte nuclear factor 1-beta (HNF1β) (MODY5) has not been well studied in the Chinese population. This study aimed to estimate its prevalence and evaluate the application of a clinical screening method (Faguer score) in Chinese early-onset diabetes (EOD) patients. Methods: Among 679 EOD patients clinically diagnosed with type 2 diabetes mellitus (age at diagnosis ≤40 years), the exons of HNF1β were sequenced. Functional impact of rare variants was evaluated using a dual-luciferase reporter system. Faguer scores ≥8 prompted multiplex ligation-dependent probe amplification (MLPA) for large deletions. Pathogenicity of HNF1β variants was assessed following the American College of Medical Genetics and Genomics (ACMG) guidelines. Results: Two rare HNF1β missense mutations (E105K and G454R) were identified by sequencing in five patients, showing functional impact in vitro. Another patient was found to have a whole-gene deletion by MLPA in 22 patients with the Faguer score above 8. Following ACMG guidelines, six patients carrying pathogenic or likely pathogenic variant were diagnosed with MODY5. The estimated prevalence of MODY5 in Chinese EOD patients was approximately 0.9% or higher. Conclusion MODY5 is not uncommon in China. The Faguer score is helpful in deciding whether to perform MLPA analysis on patients with negative sequencing results.

Objective:To analyze the epidemiological characteristics of active pulmonary tuberculosis (pulmonary tuberculosis) in Xi'an from 2013 to 2023 and predict the incidence trend of pulmonary tuberculosis in Xi'an by using autoregressive integrated moving average (ARIMA) product seasonal models to provide a decision-making basis for tuberculosis prevention and control.Methods:The incidence data of pulmonary tuberculosis reported in Xi'an from 2013 to 2023 were collected through the Tuberculosis Information Management System of the Chinese Center for Disease Control and Prevention. The Excel 2016 software was used for descriptive statistical analysis of pulmonary tuberculosis incidence data reported in Xi'an from 2013 to 2023. The SPSS 20.0 software was used to establish an ARIMA product seasonal model to predict the incidence of pulmonary tuberculosis in Xi'an.Results:A total of 49 860 cases of pulmonary tuberculosis were reported in Xi'an from 2013 to 2023, with an annual average incidence of 45.60/100 000. The incidence showed a downward trend in the past decade. The incidence was high in spring, with a peak from March to May, a small peak from November to January, and a low incidence in February and October. The annual average incidence of pulmonary tuberculosis in 2 suburban counties (52.80/100 000) was higher than that in 14 urban areas (43.21/100 000) ( χ2=20.19, P<0.001). With the increase of age, the incidence of pulmonary tuberculosis was higher, and the incidence of the males was higher than that of female ( χ2=378.34, P<0.001), the ratio of male to female incidence was 1.73∶1. The most occupation of the population was farmers, accounting for 46.54%. The established ARIMA (0, 1, 1) (1, 1, 1) 12 product seasonal model exhibited a good prediction effect, with the Bayesian Information Criterion being -1.567, the root mean square error being 0.42, and the mean absolute percentage error being 9.62. The average relative error between the actual value and the predicted value was 6.63%, and the 95% CI of the predicted value included the actual value. Conclusions:2013-2023, the incidence of pulmonary tuberculosis in Xi'an has been on the decline as a whole. Special attention should be paid to the prevention and control of tuberculosis in districts (counties) adjacent to mountainous areas in the south, people aged 60 years and above, and farmers and other vulnerable groups. The established ARIMA (0, 1, 1) (1, 1, 1) 12 product seasonal model exhibited a good predictive effect and can be applied to the short-term prediction of tuberculosis incidence.
