Objective To explore the language-social behavior of preterm infants and its influencing factors,to study the relationship between language-social behavior development and intellectual development,and to provide guidance for preterm infants' health care．Methods A self-administered general questionnaire was used to follow up 125 preterm infants until the age of 2 years,and Gesell development scale（GDS）was used to assess their language-social behavior and intellectual development．Results Preterm infants had normal language development in 43 cases（34.4%）and normal social behavioral development in 40 cases（32%）．The mean language development quotient of preterm infants was（67.99±25.75）and the mean social behavioral development quotient was（67.75±23.98）,which was at the low developmental level．There were no significant differences in gender,history of cerebral hemorrhage,regular follow-up,rehabilitation intervention,family intervention and language or social behavior（P>0.05）．Infants with different fetal age history,gestational age,and birth weight varied significantly in language and social behavior（P<0.05）;and with repeated miscarriage,small gestational age,low birth weight,showed poor language and social behavior development．Compared the children with and without moderate to severe asphyxia at birth,there was statistically significant differences in language development（P<0.05）,but in social behavior there was no significant difference（P>0.05）．The backward development of language-social behavior was accompanied by backwardness in gross motor,fine motor,and adaptive behavior in preterm infants,and the differences in the five major domains were all present and statistically significant（P<0.05）．Conclusions A major of preterm infants have poor language-social behavior development,which may be accompanied by more motor and adaptive behavior development problems;children with poor language-social behavior development have repeated miscarriage prevention at younger gestational ages,lower birth weights,or a history of moderate-to-severe asphyxia during the fetal period．It is important to give timely attention to language-social behavior in preterm infants for early detection and early intervention to improve prognosis．

Objective To evaluate the effects of flushing gastric tube by air after feeding in premature infants．Methods A total of 60 premature infants admitted to Guangzhou First People's Hospital from January 2021 to December 2021 whose gastric tube were flushed with water after feeding were selected as the control group,while 57 admitted from January 2022 to December 2022 whose gastric tube were flushed with air after feeding were selected as the study group．After 1 week of feeding,the differences of weight increase,serum albumin concentration increase,stool volume,feeding intolerance incidence and gastric tube blockage rate were compared between the 2 groups．Results No gastric tube blockage occurred．The increase of serum albumin concentration in the study group[（2.86±5.61）g/L] was significantly higher than that in the control group[（0.84±5.27）g/L]（P<0.05）,but there were no significant differences in weight increase,stool volume and feeding intolerance incidence between the 2 groups．Multiple linear regression analysis showed that the flushing gastric tube with air was an independent influencing factor for the increase of serum albumin（P<0.05）．Conclusions Flushing gastric tube with air can improve the nutritional status of premature infants,which is worthy of clinical application．
