Objective To know the faculty experiences of patients in ICU during the course of oretracheal intutation, analyze the influence of related stressor in ICU on patients, and then carry out certaincounter nursing measures according to the results.Methods Phenomenological approach was adopted in this research, 8 patients with orotracheal intubtion received interviews, the data collected from the interviews were analyzed thematically. Results Three themes were showed: a series of mental and psychiatric symptom, obviously emotional change and the aggravation of local irritation. Conclusions Scientific ICU should be build by related nursing managers, the individualization and humanization nursing cares should be used for patients in ICU to promote nursing quality.

Objective:To explore the application of fine management in clinical teaching and training of psychiatric nurses.Methods:A total of 120 newly recruited nurses from the Affiliated Kangning Hospital of Wenzhou Medical University were selected as the research subjects, and they were randomly divided into the observation group and the control group. The control group adopted the traditional teaching method, while the observation group adopted fine-management teaching method for clinical nursing interns. The pass rate of theory/operation examination, the satisfaction of doctors and nurses to the nursing level and satisfaction of patients and their families to the nursing quality were compared between the two groups.Results:The scores of the observation group were higher than those of the control group, and the differences were statistically significant ( P<0.05) . The pass rate of the theory/operation examination, the satisfaction of doctors and nurses to the nursing level and satisfaction of patients and their families to the nursing quality in the observation group were all higher than those of the control group, and the differences were statistically significant ( P<0.05) . Conclusions:The fine clinical nursing teaching and training planning can make the teaching and training work more reasonable and efficient. While improving the training efficiency, it also enables nurses to have the refined concept earlier and be more meticulous in carrying out nursing work, so as to improve quality of nursing.

Objective:To investigate the characteristics of the CD8+T cells infiltration from the 4 sub-types in medulloblastoma(MB),to analyze the relationship between CD8+T cells infiltration and prog-nosis,to study the function of C-X-C motif chemokine ligand 11(CXCL11)and its receptor in CD8+T cells infiltration into tumors and to explore the potential mechanism,and to provide the necessary clinico-pathological basis for exploring the immunotherapy of MB.Methods:In the study,48 clinical MB sam-ples(12 cases in each of 4 subtypes)were selected from the multiple medical center from 2012 to 2019.The transcriptomics analysis for the tumor of 48 clinical samples was conducted on the NanoString Pan-Cancer 10360?Panel(NanoString Technologies).Immunohistochemistry(IHC)staining of formalin-fixed,paraffin-embedded sections from MB was carried out using CD8 primary antibody to analyze diffe-rential quantities of CD8+T cells in the MB four subtypes.Through bioinformatics analysis,the relation-ship between CD8+T cells infiltration and prognosis of the patients and the expression differences of various chemokines in the different subtypes of MB were investigated.The expression of CXCR3 receptor on the surface of CD8+T cells in MB was verified by double immunofluorescence staining,and the under-lying molecular mechanism of CD8+T cells infiltration into the tumor was explored.Results:The charac-teristic index of CD8+T cells in the WNT subtype of MB was relatively high,suggesting that the number of CD8+T cells in the WNT subtype was significantly higher than that in the other three subtypes,which was confirmed by CD8 immunohistochemical staining and Gene Expression Omnibus(GEO)database analysis by using R2 online data analysis platform.And the increase of CD8+T cells infiltration was posi-tively correlated with the patient survival.The expression level of CXCL11 in the WNT subtype MB was significantly higher than that of the other three subtypes.Immunofluorescence staining showed the presence of CXCL11 receptor,CXCR3,on the surface of CD8+T cells,suggesting that the CD8+T cells might be attracted to the MB microenvironment by CXCL11 through CXCR3.Conclusion:The CD8+T cells infiltrate more in the WNT subtype MB than other subtypes.The mechanism may be related to the activation of CXCL11-CXCR3 chemokine system,and the patients with more infiltration of CD8+T cells in tumor have better prognosis.This finding may provide the necessary clinicopathological basis for the regulatory mechanism of CD8+T cells infiltration in MB,and give a new potential therapeutic target for the future immunotherapy of MB.
