The pulmonary complications associated with inflammatory bowel disease (IBD) predominantly affect the airways, with bronchiectasis being the most frequently observed condition. Concurrently, there is a notable increase in the prevalence of IBD among individuals with pulmonary disorders. This trend suggests a possible reciprocal relationship between IBD and pulmonary diseases, indicative of the "gut-lung axis" at play. The etiology of bronchiectasis in the context of IBD remains elusive, and there is a dearth of effective clinical tools for monitoring and prevention. This paper delves into the pathogenesis of IBD-related bronchiectasis, with a particular emphasis on the role of the gut-lung axis in this scenario. It scrutinizes the impact of immune responses and dysbiosis of the microbiome on the chronic inflammation observed in both the intestinal tract and the respiratory system.

Objective To explore the relationships between the screen time with parent-child relations as well as social ability and behavioral problem in preschool children.Methods A total of 866 children aged 3-6 years old in Dazhou City conducted the sampling survey by adopting the children screen time questionnaire,parent-child relationship self-rating scale and young children's social ability and behavior assessment scale(SCBE-30).The single factor analysis and multinomial Logistic regression method were used to conduct the statistical analysis.Results The surveyed preschool children watching TV every day accounted for 99.31 ％,those playing mobile phones every day accounted for 81.87％ and those using computer accounted for 68.36％s.The average daily screen time at ordinary time was 1.75 h/d,those ≥2 h/d accounted for 16.05％;the average screen time at the weekend was 2.32 h/d,those ≥2 h/d accounted for 46.57％.The univariate analysis showed that the screen time in boy,left behind children,only child,mothers engaging in agriculture of peasant-worker or housewife was longer(P＜0.05);the screen time affected the social ability and behavior problems of children(P＜0.05).The longer the time children spent with their parents every day,the higher the parent-child relationship score(P＜0.05);the screen content affected the parent-child relationship and anxiety withdrawal behavior (P＜0.05).The polynormial regression analysis between the children's screen time with social ability,behavior problems,parent-child relation and contacting screen mode showed that the screen time had the negative effect relation with the social ability and parent-child relation(parents and children questionnaire) score(β=-1.115,-1.728,-1.909,P＜0.05),and had the positive effect relation with the scores of anger attack behavior and anxiety retreat behavior,and individual contacting screen (β=0.982,1.474,0.877,P＜0.05).Conclusion The screen time in preschool children is related with parent-child relation,social ability and behavioral problems.The parental accompany is beneficial to the development of parentchild relations in preschool children.
