Objective:To summarize the first aid and nursing experience of a patient with upper gastrointestinal bleeding induced by Dieulafoy disease after liver transplantation.Methods:One case with upper gastrointestinal bleeding induced by Dieulafoy disease after liver transplantation was given a series of treatment and nursing measures, including identify bleeding manifestations, providing emergency nursing measures, nutritional support treatment, establishing infection prevention and control system, implementing prone ventilation and pulmonary function rehabilitation, precise immunosuppressive therapy, various forms of psychological care in the First Hospital of Jilin University in November 22, 2021.Results:After 58 d of careful treatment and nursing, the patient recovered and was discharged.Conclusions:Dieulafoy disease is a critical disease, and early diagnosis and targeted first aid and predictive care for liver transplant patients with such diseases are the key to promoting recovery.

Objective To investigate the current status about personal mastery in paediatric nurses in a tertiary hospital in Changchun and to analyse the influencing factors.Methods A total of 340 paediatric nurses in the hospital were enrolled in the investigation with the methods of general data questionnaire,personal mastery scale(PMS),nurses'perceived professional benefits scale(NPPBS)and practice environment scale(PES).Results 321 paediatric nurses complete the research.The total score of personal mastery among the paediatric nurses was found at(27.63±1.99)and was at a middle-high level.Multiple linear regression analysis showed the overall independent factors that affected the overall personal mastery of the paediatric nurses included type of job contract,average monthly income,working experience,number of night shifts per month,the perceived professional benefits and practice environment of the nurses(P<0.05).Conclusion Personal mastery among the paediatric nurses is at a middle-high level.Nursing managers should take targeted and pertinent measures to the identified influencing factors in order to improve the personal mastery,relieve work related pressures,reduce job burnout,enhance professional identity and thereby promote the stability and development the workforce in paediatric nursing.

Objective:RNA interference technology (siRNA) was used to inhibit the expression of DJ-1 gene in lung squamous cell carcinoma HTB-182 cells, then, tandem affinity purification mass spectrometry (TAP-MS) was performed to screen the interacting proteins of DJ-1 in lung cancer cell line of HTB-182.Methods:The siRNA lentivirus vector targeting DJ-1 gene was constructed to infect HTB-182 cells (DJ-1 siRNA group), and the lentivirus vector control group (control siRNA group) and blank control group were established. The expression level of DJ-1 protein was detected by Western blot, and the endogenous DJ-1 protein silenced si-DJ-1-HTB-182 cells were established. The specific primers of DJ-1 were designed, and the DJ-1 expression plasmid pNTAP-DJ-1 with streptomycin binding peptide label (SBP) and calmodulin binding peptide label (CBP) was constructed. The cell line DJ-1 siRNA HTB-182 was stably transfected with liposome, and the positive clones were screened by G418. The positive clones were verified by Western blot, and the interacting proteins of DJ-1 were found by TAP-MS.Results:The protein expression of DJ-1 in DJ-1 siRNA interference group was significantly lower than that in empty plasmid group and blank control group ( P<0.05); HTB182 cell line stably expressing pNTAP-DJ-1 plasmid was successfully constructed; Three proteins interacting with DJ-1 were screened by TAP-MS: cytokeratin 1 (keratin 1), cytokeratin 10 (keratin 10) and NADPH oxidase activating protein P47 (P47 Px). Conclusions:Keratin 1, Keratin l0 and P47 Px protein may be DJ-1 interactions protein.

Objective@#To investigate the clinical manifestation, cytogenetics, gene mutations and prognostic factors of chronic neutrophilic leukemia (CNL) .@*Methods@#16 CNL cases, according to WHO (2016) -definition, were reviewed retrospectively. Identifications of the CSF3R, ASXL1, SETBP1, CALR and MPL mutations were performed by direct sequencing. JAK2 V617F mutation was detected by AS-PCR.@*Results@#Of the 16 CNL patients, the median age was 64 (43-80) years with a male predominance of 75% (12/16) . The median hemoglobin was 114 (81-154) g/L, with median WBC of 41.20 (26.05-167.70) (109/L and median PLT of 238 (91-394) ×109/L.The median level of marrow fibrosis (MF) was 1 (0-3) degree. There was no other cytogenetic abnormalities except t (1;7) (p32;q11) , +21 and 14ps+ for each. All the 16 CNL patients harbored CSF3R T618I mutation. ASXL1 mutations were identified in 81% (13/16) , while SETBP1 mutations were confirmed in 63% (10/16) . The CALR K385fs*47 mutation was found. There was no mutation in JAK2 V617F or MPL in the above 16 patients. The median overall survival (OS) of patients presented with WBC≥50×109/L at diagnosis (11 months) was significantly shorter than of WBC<50×109/L (39 months, P=0.005) .@*Conclusion@#CSF3R T618I mutation was specific for CNL. The median OS of CNL patients was 24 months, and WBC≥50×109/L at diagnosis was an unfavorable prognostic factor.
RÉSUMÉ
<p><b>OBJECTIVE</b>To observe the CSF3R, ASXL1, SETBP1, JAK2 V617F and CALR mutations in patients with chronic neutrophilic leukemia (CNL).</p><p><b>METHODS</b>Twelve suspected "CNL" patients were retrospectively reviewed according the WHO criteria (2008). CSF3R,ASXL1,SETBP1 and CALR mutations were sequenced, and JAK2 V617F was tested by allele specific (AS)-PCR.</p><p><b>RESULTS</b>6 of 12 cases were diagnosed as CML, and all of the 6 carried. 4 of 6 patients also had ASXL1 and SETBP1 mutations and one had a CALR mutation (c.1154-1155insTTGTC). Two patients with monoclonal gammopathy with uncertain significance (MGUS) combined with CNL-like symptoms had no CSF3R, ASXL1, SETBP1, JAK2 V617F or CALR mutation. The same results were also seen in other 4 cases with secondary neutrophilic leukocytosis.</p><p><b>CONCLUSION</b>CSF3R, ASXL1 and SETBP1 mutations differential diagnosis of CNL, and should be included in the diagnostic protocol so as to improve diagnostic accuracy for CNL.</p>
