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.

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 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.

ObjectiveTo describe the characteristics of the nasopharyngeal microbiota in children under 5 years of age in Haidong City, Qinghai Province and analyze its associated factors, so as to provide basic data for the evolution and development of nasopharyngeal microbiota in children. MethodsA total of 230 community children from Haidong City, Qinghai Province were included in the study. Participants’ basic information was collected by local volunteers from parents/guardians at enrollment. 16S rDNA sequencing was used to identify the bacterial diversity and abundance of nasopharyngeal microbial community. Bioinformatics methods were used to analyze the characteristics of the nasopharyngeal microbiota, compare the differential species, and investigate the correlation with age. ResultsThere was no statistical difference in either Chao1 index or Shannon index of nasopharyngeal microbial communities among children with different ages (P>0.05). Besides, the structure of nasopharyngeal microbiota in children of different ages was different, either (P=0.020). Age, ethnicity and delivery mode, to some extent, could explain the differences in the structure of nasopharyngeal microbiota in children. There were statistically significant differences in the abundance of Dolosigranulum, Staphylococcus and Corynebacterium in the nasopharyngeal microbiota of children with different ages (P<0.05). Differential analysis revealed that Corynebacterium was found to be over-represented in children under 1 year of age, while Dolosigranulum was found to be over-represented in children between 2 and 3 years old. Furthermore, the results of correlation analysis showed that, Moraxella was positively correlated with Corynebacterium, Dolosigranulum and Streptococcus, but negatively correlated with Pseudomonas. In addition, a strong positive correlation was detected between the Dolosigranulum and Corynebacterium. ConclusionThe diversity of nasopharyngeal microbial community among children under 5 years in Haidong City, Qinghai Province is stable. However, there are differences in the species structure, mainly in the abundance difference of Dolosigranulum, Staphylococcus and Corynebacterium. This study provides basic data on the evolution and maturation of nasopharyngeal microbial communities in early childhood, which can provide a scientific basis for the early prevention and diagnosis of respiratory tract infections in children.
