Objective:To investigate the efficacy and assess the safety of transnasal nebulisation of budesonide in children with adenoid hypertrophy. Methods:Children with adenoid hypertrophy who attended the Children's Hospital of Zhejiang University School of Medicine between December 2021 and December 2022 were randomly assigned to budesonide high-dose group（Group A: budesonide 1 mg/dose + saline nasal rinse）, budesonide low-dose group（Group B: budesonide 0.5 mg/dose + saline nasal rinse）, and control group（Group C: saline nasal rinse）, and each group 20 children were collected separately, The efficacy and safety of transnasal nebulisation of budesonide in children with adenoid hypertrophy were assessed by comparing the symptomatic VAS scores, adenoidal nasopharyngeal lateral radiographs A/N values, nocturnal sleep oximetry（SaO2）, and the incidence of adverse events during the treatment period of 8-week in the three groups. Results:The 8-week baseline differences in adenoid A/N values were statistically different between groups A and B（P<0.001） and A and C（P=0.022）, with the reduced amount in adenoid volume being most pronounced in group A, which differed from the other two groups. With the increase of intervention time, SaO2 levels gradually increased（F=154.725, P<0.001） and VAS scores gradually decreased（F=165.616, P<0.001） in all three groups. After 8 weeks of treatment, there was no statistically significant difference in SaO2 level（P=0.085） between groups A and B. There was a statistically significant difference in VAS total scores between Group A and Group B （P < 0.05） . The improvement of SaO2and total VAS score in group A was higher than that in group B. There was a statistically significant difference in the comparison of SaO2 level and total VAS score between groups A and B, and between groups A and C（P<0.01）; after the intervention of the three groups, showing the greatest improvement of total VAS score and SaO2in the group A, followed by Group B. There was no statistically significant difference in the incidence of adverse events among Groups A, B, and C throughout the trial. Conclusion:The treatment of children with adenoid hypertrophy by intranasal nebulisation of budesonide suspension has good efficacy and safety, which is conducive to reducing the size of adenoids, improving the clinical symptoms of children with adenoid hypertrophy, and improving the SaO2of nocturnal sleep, and it has a certain clinical application value.

Objective To investigate the fertility history and demand for reproductive health services of new residents in Shanghai. Methods A questionnaire survey was conducted among 1 358 new residents in 36 survey sites in 7 districts of Shanghai from July to September 2020. The content includes fertility history， induced abortion history， demand for reproductive health-related services， awareness rate of the Shanghai Family Planning Association and service access rate， etc. Results Among the new residents themselves and their spouses/sexual partners， 31.3% （374/1 194） had been pregnant once and 33.6% （401/1 194） had been pregnant twice； 46.3% （533/1 194）had one child and 29.7% （355/1 194）had two children. The difference of number of births among new residents with different residence time， those who did or did not possess permanent residency or residence permits， and those from different sources （urban or rural） was statistically significant （ χ ²=158.664， 50.263， 16.011， 114.419， all P <0.001）. Among the new residents themselves and their spouses / sexual partners， the proportion of induced abortion of more than once was 36.1%. The difference of the number of abortions of new residents with or without permanent residency was statistically significant （ χ ²=19.389， P <0.001）. The awareness rate of new residents of the harm of induced abortion to health was 92.1% （1 100/1 194）； There were significant differences in the scientific knowledge of harm of induced abortion to health among new residents with different local residence time and those with or without a residence permit （ χ ²=36.590， 20.926， both P <0.001）. The awareness rate of the Family Planning Association was 82.6% （986/1 194）， and the service access rate was 51.3% （613/1 194）. Permanent residency and residence permits are the main factors that affect the service accessibility of the Shanghai Family Planning Association. 44.8% （535/1 194） of new residents hope to receive reproductive health services in their place of residence， and they are most concerned about knowledge on good prenatal and postnatal care. Conclusion We should further publicize the "three-child" fertility policy， advocate a friendly fertility culture， and provide new residents with people-centered and accurate reproductive health services adapted to their needs through multi-sectoral cooperation， so as to improve their reproductive health level.

Objective:To investigate the knowledge, attitudes, and practices (KAP) of pulse oximetry among pediatric healthcare providers in China and analyze the factor influencing the KAP.Methods:A self-developed questionnaire was used for an online research on the KAP of 11 849 pediatric healthcare providers from 31 provinces, autonomous regions, and municipalities of China from March 11 to 14, 2022.The factors influencing the KAP of pulse oximetry among pediatric healthcare providers were examined by Logistic regression. Results:The scores of KAP, of pulse oximetry were 5.57±0.96, 11.24±1.25 and 11.19±4.54, respectively.The corresponding scoring rates were 69.61%, 74.95%, and 55.99%, respectively. Logistic regression results showed that the gender and working years of pediatric healthcare providers, the region they were located, and whether their medical institution was equipped with pulse oximeters were the main factors affecting the knowledge score (all P<0.05). Main factors influencing the attitude score of pediatric healthcare providers included their knowledge score, gender, educational background, working years, region, medical institution level, and whether the medical institution was equipped with pulse oximeters (all P<0.05). For the practice score, the main influencing factors were the knowledge score, gender, age, and whether the medi-cal institution was equipped with pulse oximeters (all P<0.05). Conclusions:Chinese pediatric healthcare providers need to further improve their knowledge about and attitudes towards pulse oximetry.Pulse oximeters are evidently under-used.It is urgent to formulate policies or guidelines, strengthen education and training, improve knowledge and attitudes, equip more institutions with pulse oximeters, and popularize their application in medical institutions.
