Objective:To investigate the changes of the distribution and drug resistance profile of bacteria from ICU children with lower respiratory tract infection (LRTI) in Suzhou City, Jiangsu Province from 2017 to 2022.Methods:From January 2017 to December 2022, a cross-sectional observational study on the bacterial spectrum analysis among intensive care unit (ICU) children with LRTI was conducted in Children′s Hospital of Soochow University. The bacteria was cultivated by culture methods from sputum samples, and identified by MALDI-TOF mass spectrometry. Drug sensitivity tests were performed by the VITEK2 Compact fully automated analysis system and the paper slide method. The χ2 test or Fisher′s exact probability was used to analyze the changes of the distribution of sputum culture-positive bacteria and drug resistance in ICU children. Results:The overall detection rate of sputum culture was 42.06% (1 182/2 810). Staphylococcus aureus (25.63%,303/1 182), Acinetobacter baumannii (13.62%,161/1 182) and Haemaphilus influenzae (13.28%,157/1 182) were the top three. Proportions of Acinetobacter baumannii (17.90% vs. 11.02%, χ2=11.17, P=0.001), especially carbapenem-resistant Acinetobacter baumannii (43.70% vs. 23.50%, χ2=15.21, P<0.001) increased significantly from 2020 to 2022. However, the proportions of Haemophilus influenzae (8.50% vs. 16.19%, χ2=14.27, P<0.001), Streptococcus pneumoniae (8.50% vs. 15.92%, χ2=13.42, P<0.001) and extended-spectrum-lactamase producing Escherichia coli (8.89% vs. 18.00%, χ2=5.45, P=0.025) decreased. Drug resistant results showed that Acinetobacter baumannii was obviously more resistant to imipenem ( χ2=4.43, P=0.035) and levofloxacin ( χ2=12.53, P<0.001), while more sensitive to minocycline ( χ2=8.34, P=0.004). Escherichia coli showed a significant increase in resistance to piperacillin tazobactam ( χ2=8.29, P=0.008) and cefoperazone sulbactam ( χ2=5.07, P=0.024) from 2020 to 2022; Klebsiella pneumoniae consistently maintained a resistance rate of more than 60% to first and second-generation cephalosporins, and remain susceptible to quinolones and carbapenems. Staphylococcus aureus remained highly susceptible to levofloxacin (drug resistance rate: 2.31%,7/303) and sulfamethoxazole/trimethoprim (drug resistance rate: 4.95%,15/303) from 2020 to 2022. Conclusion:Higher detection and resistance rates of Acinetobacter baumannii from sputum culture in ICU children from 2020 to 2022 were explored. Resistance of Escherichia coli to β-lactamase inhibitor combinations was more serious. Regular monitoring the changes of the etiology of respiratory tract infections in ICU Children is particularly important for the prevention and treatment of multidrug-resistant bacterial infections.

Objective To investigate the clinical value of auditory brainstem response(ABR)wave Ⅰ latency and 1 000 Hz acoustic immittance in the assessment of middle ear function in infants.Methods A total of 74 infants who were born within 6 months of age from 2020 to 2021 were selected,with a total of 148 ears.According to the click ABR(hereinafter referred to as ABR)threshold,they were divided into mild group(56 ears),moderate group(14 ears)and normal group(78 ears).The ABR wave Ⅰ latency and 1 000 Hz acoustic immittance results were ana-lyzed respectively.Results The Kappa values between ABR wave Ⅰ latency and 1 000 Hz tympanometry in infants of mild and moderate groups were 0.708 and 0.650,respectively.There was no significant difference in the detec-tion rate of middle ear function abnormality(P＞0.05)in infants with mild and moderate threshold impairment within 6 months of age.The paried Chi-square test showed a significant difference between the ABR wave Ⅰ latency and 1 000 Hz acoustic immittance in infants with normal threshold at 6 month of age(P＜0.05),with a Kappa val-ue of 0.297.Conclusion The middle ear function could be evaluated by ABR wave Ⅰ latency or 1 000 Hz acoustic immittance in 6-month-old infants with mild or moderate abnormality.For infants with normal ABR threshold,1 000 Hz acoustic immittance and the latency of ABR wave Ⅰ need to be cross-verified.

Objective:To investigate the application value of auditory steady-state response (ASSR) combined with short sound auditory brainstem response (ABR) for hearing assessment in children with sensorineural hearing impairment, providing evidence for clinical diagnosis of the disorder.Methods:A total of 90 children with sensorineural hearing impairment who received treatment at Jiaxing Maternity and Child Health Care Hospital from January 2020 to June 2021 were included in this prospective study. These children were randomly divided into a control group and an observation group ( n = 45 per group). The children in the control group underwent ABR testing, while those in the observation group underwent ASSR testing in addition to ABR thresholds testing. The hearing impairment was compared between the two groups. The ABR and ASSR thresholds were compared among children with different degrees of hearing impairment. The correlation between ABR and ASSR at 2 and 4 kHz carrier frequencies was analyzed in the observation group. Results:The abnormal rate of hearing in the observation group was 68.89% (31/45), which was significantly higher than 44.44% (20/45) in the control group ( χ2 = 5.48, P = 0.019). At a carrier frequency of 0.5 kHz, the ASSR thresholds of children with moderate and severe hearing impairment in the observation group were (63.11 ± 6.82) dB nHL and (84.65 ± 5.31) dB nHL, respectively, which were significantly higher than the ABS thresholds (56.12 ± 4.63) dB nHL and (76.87 ± 5.15) dB nHL ( t = 2.94, 2.78, both P < 0.05). There was a positive correlation between ABR and ASSR thresholds at 2 and 4 kHz carrier frequencies in children with different degrees of hearing impairment in the observation group ( r = 0.896, 0.901, both P < 0.05). Conclusion:The combination of ABR and ASSR testings is more accurate in judging the degree of hearing impairment in children with sensorineural hearing impairment than the ABR testing, and can provide a reliable basis for later clinical treatment.

As a model organism, zebrafish have many advantages over other animal models and is suitable for studies on establishment of human disease model and mechanism.In zebrafish, there are two phases of endocrine formation during early development, which are directed by concomitant activity of many signaling pathways.Zebrafish pancreas possess similar cell structure with that of other animals, which can express various endocrine hormones including insulin.The main organs required for metabolic control, such as the pancreas, islet, and insulin sensitive tissue (muscle, liver) are conserved in zebrafish, and the mechanisms of glucose regulation in zebrafish is similar to that seen in mammalian models.These render it an excellent model to study glucose metabolism.Hyperglycemia in zebrafish model can be induced by administration of the diabetogenic drug, streptozotocin (STZ), alternatively immersion of the fish in glucose solution and water, or disturbing of signaling pathways associated with glucose metabolism.Glucose levels in adult zebrafish blood or embryo tissue and phenotype of retinal cell layers or retinal vasculature are the commonly used measurement organs in zebrafish diabetic models.

With the universal two-child policy implementation, the birth rate increased, posing challenges to pediatrician allocation. Based on the birth rate, we calculated pediatrician demands and gaps during the period from 2016 to 2020 by the method of health service demand. The results showed that except Beijing and Shanghai, the ped-iatrician supply and demand ratios are less than 0 . 80 and additional numbers of pediatricians ranging from 191 981 to 198 287 are needed to meet the service demands. We recommend increasing the number of pediatricians taking both national supply-demand ratios and gaps by rationally using reasonable enrolment quota and improving the treatment and other reasonable ways to increase pediatricians. In addition, we should enhance information disclosure and guid-ance, and improve the hierarchical hospital visit system to alleviate the pressure of big cities.

With the universal two-child policy implementation, the birth rate increased, posing challenges to the maternity beds resource allocation. Based on the birth rate and the method of health service demand, we calculat-ed the maternity beds demands and gaps during the period from 2016 to 2020 . Results showed that numbers between 73 478 and 99 004 of maternity beds are needed annually and mainly allocated to eastern and central areas as well. In addition, the maternity beds of different delivery institutions should be adjusted and the hierarchical diagnosis system should be improved in order to alleviate the pressure of the obstestric acceepts in big cities like Beijing and Shanghai.
