ABSTRACT
Objective:To explore the clinical correlation between peripheral blood basophil levels and chronic sinusitis （CRS） subtypes. Methods:One hundred and twenty-six patients with CRS and 103 healthy cases from physical examination admitted to the First Affiliated Hospital of Soochow University from January 2021 to October 2022 were retrospectively analyzed. According to the histopathological classification, CRS patients were divided into eosinophilic chronic sinusitis （eCRS） group （47 cases） and non eosinophilic chronic sinusitis （non-eCRS） group （79 cases）. The differences among the three groups in peripheral blood inflammation cell counts, eosinophils-to-basophils ratio（bEBR）, basophils-to-neutrophils ratio（BNR）, basophils-to-lymphocytes ratio（BLR）, basophils-to-monocytes ratio（BMR） were compared, and study the correlation between each index and Lund-Mackay score, and the correlation between basophils in peripheral blood and other inflammatory cells. Results:The counts of basophils in the peripheral blood of the healthy control group, eCRS group and non-eCRS group were 0.03±0.01, 0.04±0.02, 0.03±0.02, respectively, the eosinophils-to-basophils ratio（bEBR） were 5.64±4.22, 8.38±5.95, 4.55±3.90, the basophils-to-neutrophils ratio（BNR） were 0.01±0, 0.01±0.01, 0.01±0.01, and the basophils-to-lymphocytes ratio（BLR） were 0.01±0.01, 0.02±0.01, and 0.02±0.01, respectively, the basophils-to-monocytes ratio（BMR） were 0.08±0.04, 0.11±0.06, and 0.08 ±0.04 respectively. There was a statistically significant difference between eCRS group and healthy control group, non-eCRS group（P<0.01）, while there was no statistically significant difference between non-eCRS group and healthy control group（P>0.05）. Basophil counts （r=0.185 5, P<0.05）, BLR（r=0.226 9, P<0.05）, BMR（r=0.228 1, P<0.01） in patients with CRS were positively correlated with Lund Makey score. In addition, basophils were also positively correlated with eosinophils（r=0.479 2, P<0.01）, lymphocytes（r=0.259 4, P<0.01）, and monocytes（r=0.256 4, P<0.01） in patients with CRS. Conclusion:The peripheral blood basophil count, BLR and BMR were significantly increased in eCRS, and were significantly positively correlated with Lund -Makey score. It has the potential to develop into disease biomarkers and new therapeutic targets of eCRS.

Objective:To investigate the effect of a breathing pattern intervention (RPI) on the oral feeding of pre-term infants with suck-swallow-breath (SSwB) coordination disorder.Methods:Sixty pre-term infants with SSwB coordination disorder were divided into an observation group ( n=30) and a control group ( n=30) using a random number table. Both groups were given routine feeding training, including oral exercise intervention, non-nutritive sucking training, and swallowing induction training during nursing, while the observation group was additionally provided with 15 minutes of breathing pattern training once a day, including breathing pattern observation, resistive breathing training prior to eating and passive breathing pattern intervention during eating. Before and after the 7-day intervention, the Pre-term Infant Oral Feeding Readiness Assessment (PIOFRA) was used to evaluate each subject′s oral feeding ability. Rate of transfer (RT), proficiency (PRO), minimum oxygen partial pressure (SaO 2) and SaO 2 fluctuations were also recorded during the feeding process. Results:After 1 week of the intervention, significant improvement was observed in both groups. In the observation group the average RT (2.76±0.36ml/min), PRO, minimum SaO 2, the number of SaO 2 fluctuations, and PIOFRA score (33.28±0.58) were all significantly better than the control group′s averages. Conclusion:Breathing pattern intervention based on routine feeding training can enhance breathing coordination during swallowing and ultimately improve the oral feeding of pre-term infants with SSwB coordination disorders in a relatively short period of time.
