Objective To explore the relationships between inappropriate parenting styles,emotional regulation strategies and self-injury.Methods A total of 1 096 medical students anonymously completed adolescents self-harm scale,emotion regulation scale (ERS) and the rejection and over-protection subscales of parental bonding instrument (PBI).Results The scores of paternal rejection,maternal rejection,paternal over-protection,maternal over-protection,cognitive reappraisal,expression suppression and self-injury were (4.3±3.3),(3.9±3.0),(5.7±3.3),(6.1±3.5),(36.1±6.7),(25.7±7.4) and (1.0±2.9),respectively.The scores of self-injury were positively correlated with the scores of paternal rejection,maternal rejection,paternal over-protection,maternal over-protection and expression suppression (r =0.08-0.20,P＜ 0.01),meanwhile negatively correlated with the scores of cognitive reappraisal(r=-0.10,P＜0.01).Cognitive reappraisal mediated the relationship between parental rejection and self-injury,which accounted for 9.3％.Expression suppression mediated the relationship between parental rejection,parental over-protection and self-injury,which accounted for 14.5％ and 17.9％,respectively.Conclusion The emotion regulation strategy act as a mediator between the inappropriate parental styles and self-injury in medical students.In addition,different emotion regulation strategies (cognitive reappraisal and expression suppression) play different roles in such relationship.

Objective:To evaluate the effects of Preventing Jaundice and Antibacterial Biological Medical Gel in prevention of hyperbilirubinemia and umbilical infection in newborn.Methods:A total of 600 healthy neonates in a tertiary hospital were selected. Participants were randomly divided into the control group ( n=300) and the observation group ( n=300). The control group was given routine nursing guidance while the observation group was treated with Preventing Jaundice and Antibacterial Biological Medical Gel. The differences in the number of times of the fetus feces in 3 days after birth, the first fetal feces, yellow discharge time of the fetus feces, the incidence of hyperbilirubinemia, the incidence of neonatal phototherapy and the incidence of umbilical infection between the two groups were compared. Results:The number of times of the fetus feces in 3 days after birth and the first fetal feces and yellow discharge time of the fetus feces of the observation group were (8.12±1.36) times, (7.39±3.71) hours, (26.05±3.98) hours, respectively. The control group were (5.31±1.02) times, (13.04±5.26) hours, (28.65±3.54) hours, respectively. The difference between the two groups was significant ( Z value was -6.133, -6.483, t value was -19.011, P<0.05). The incidence of hyperbilirubinemia, being in neonatal intensive care unit, the incidence of blue light irradiation and the incidence of umbilical infection of the observation group was 0.67%(2/300), 0, 1.00%(3/300) and 0, respectively. The control group was 3.33%(10/300), 2.00%(6/300), 5.00%(15/300) and 3.33%(10/300), respectively. the difference between the two groups was significant ( χ2 value was 4.209-8.247, P<0.01). Conclusions:Preventing Jaundice and Antibacterial Biological Medical Gel could help control the incidence of hyperbilirubinemia and reduce the umbilical infection. It is worth clinical spreading.

OBJECTIVE To explore the perioperative risk factors in young children with obstructive sleep apnea.METHODS The 86 young OSA children admitted to Kunming Children's Hospital from January 2020 to December 2022 were divided into general ward group and ICU ward group according to their postoperative treatment.The clinical data of the two groups were compared and analyzed.RESULTS The course of disease and operation time of children in ICU ward group were significantly longer than those in general ward group,OAHI and ODI were significantly greater than those in general ward group,the intraoperative blood loss was significantly more than that in general ward group,MSaO2 and LSaO2 were significantly lower than those in general ward group,and the tonsil size and operation method composition ratio were significantly different from those in general ward group(P<0.05).There were no significant differences in sex composition ratio,age,weight,height,BMI and adenoid size grading ratio between the two groups(P>0.05).The OAHI values of the two groups were significantly negatively correlated with MSaO2 and LSaO2(r=-0.676,-0.724),and significantly positively correlated with tonsil size grade,ODI,operation time and intraoperative blood loss(r=0.242,0.967,0.321,0.446,P<0.05).There was no significant correlation with the course of disease(r=0.172,P>0.05).Multiple linear regression analysis showed that LSaO2 and ODI were independent risk factors for the severity of the child's condition.CONCLUSION The severity of the condition in young OSA children determines the perioperative risk and is influenced by the type of surgery.LSaO2 and ODI are independent risk factors which should be taken seriously by clinicians.
