Objective To explore the association of IL-10-592A/C polymorphism with the susceptibility to respiratory syncytial virus(RSV) bronchiolitis and disease severity,and to explore the impact of IL10-592A/C polymorphism upon total serum IL-10 levels in children with RSV bronchiolitis. Methods One hundred children (patients group) admitted to hospital with RSV bronchiolitis and 100 healthy children (control group) were recruited. PCR restriction length fragment polymorphism assay was used to detect the single nucleotide polymorphisms of IL-10-592A/C. Total serum IL-10 levels in patients group were assayed with ELISA. Results The genotype frequency of IL-10-592A/C were AA 44% ,AC 38% ,CC 18% in patients group ,and AA 41% ,AC 42% ,CC 17% in the control group,it showed no significant difference between two groups (χ2= 0. 33, P > 0. 05) . The frequency of each allele were A 63%, C 37 % in patient group, and A 64% ,C 36% in the control group,there was no significant difference in allele frequency between two groups (χ2=0. 43 ,P >0. 05) . There was no significant difference in total serum IL-10 levels between different genotype of IL-10-592A/C (F = 0. 87, P > 0. 05) . The differences in genotype frequency of IL-10-592A/C were not significant between mild and moderate to severe cases (χ2= 2. 67, P > 0. 05) . Conclusion IL-10-592A/C gene polymorphisms do not correlated with RSV bronchiolitis.

This article reviews the overview, impact and intervention measures of adult attachment of main caregivers of dementia patients, in order to provide a basis for my country to carry out targeted intervention measures to improve the health outcomes of the main caregivers.

Objective:To explore the effects of family-centered conductive education on the muscle strength in children with cerebral palsy and the stress of caregivers.Methods:Totally 92 children with cerebral palsy and 92 their main caregivers admitted into the Affiliated Hospital of Jining Medical University from October 2018 to December 2019 were selected and divided into a control group and a conductive education group according to the random number table, with 46 children with cerebral palsy and their 46 main caregivers in each group. Patients in the control group received routine care, while patients in the conductive education group underwent family-centered conductive education on the basis of routine care. The Chinese version of the Modified Ashworth Scale (MAS) , Caregiver Strain Index (CSI) , and the Chinese version of Family Management Measure (FaMM) were used to evaluate the muscle strength, caregiver pressure, and disease management ability of the two groups before and after intervention. Therefore, there were actually 43 cases in the control group and 42 cases in the conductive education group.Results:After intervention, the MAS scores of the two groups were lower than those at admission, and the score was lower in the conductive education group than in the control group, with statistically significant differences ( P<0.05) ; the CSI score of caregivers in the conductive education group was lower than that in the control group, and the difference was statistically significant ( P< 0.05) , while the FaMM score was higher than that in the control group, with statistically significant difference ( P<0.05) . Conclusions:Family-centered conductive education can effectively reduce the muscle strength of children with cerebral palsy, alleviate the pressure of their caregivers, and improve the caregivers' disease management ability.

Objective:To investigate the Chinese anesthesiologist′s proficiency, training experience and needs of flexible bronchoscope-guided awake flexible bronchoscopy intubation (AFBI) using a questionnaire method.Methods:The cluster sampling was used, and self-designed questionnaires that addressed 54 questions in 5 categories were distributed through WeChat and online platforms. The survey took one month, and the answers were automatically recorded by the WeChat server.Results:A total of 1 250 anesthesiologists participated in the survey in 30 provinces of China, 9 of them were not anesthesiologists, and 1 241 (99.28%) questionnaires were validated. In the valid questionnaires, 52.70% (654) of the anesthesiologists were from tertiary hospitals, and 74.78% (928) of the anesthesiologists were attending physicians or above, only 7.57% (94) of the anesthesiologists had sufficient confidence in AFBI. Twenty-five point two two percent (313) of the anesthesiologists preferred fiberoptic intubation as the first tool when dealing with the anticipated difficult airway. Forty-eight point one one percent (597) of the anesthesiologists had implemented AFBI. Among them, 80.74% (482) had experienced unsuccessful AFBI practices. Eight hundred and ninety-four anesthesiologists had received AFBI training, and the most common AFBI training strategy was theoretical lectures. In addition, the degree of satisfaction regarding the theoretical lectures quality, technical training, clinical practice relativity and non-technical skills training was 21.47% (192), 14.32% (128), 12.3% (110) and 17.90% (160), respectively. The degree of satisfaction with all the 4 training elements mentioned above was 7.27% (65).Conclusions:The awareness and practice of Chinese anesthesiologists in terms of clinical application of AFBI to treat difficult airways need to be strengthened at present, and the lack of high-quality AFBI training may be the key.
