Objective:In order to explore the impact of corona virus disease 2019(COVID-19)on the hospitalization of children with bronchiolitis and to improve clinicians′ understanding of the characteristics of bronchiolitis during the COVID-19 epidemic.Methods:This was a multicenter clinical study, and the data have been collected from 23 children′s medical centers in China.All the clinical data were retrospectively collected from children with bronchiolitis who were hospitalized at each study center from January 1, 2019 to December 31, 2021.The results included gender, age at hospitalization, length of stay, respiratory syncytial virus(RSV) test results, severity rating, ICU treatment, and the total number of children hospitalized with respiratory tract infection during the same period.The clinical data of children with bronchiolitis in 2019 before COVID-19 epidemic and in 2020、2021 during COVID-19 epidemic were statistically analyzed and compared.Results:According to a summary of data provided by 23 children′s medical centers, there were 4 909 cases of bronchiolitis in 2019, 2 654 cases in 2020, and 3 500 cases in 2021.Compared with 2019, the number of bronchiolitis cases decreased by 45.94% in 2020 and 28.70% in 2021.In 2019, 2020 and 2021, there were no significant differences in gender ratio, age, and duration of hospitalization.Compared with 2019, the ratio of bronchiolitis to the total number of hospitalizations for respiratory tract infection decreased significantly in 2020 and 2021( χ2=12.762, P<0.05; χ2=84.845, P<0.05).The proportion of moderate to severe bronchiolitis cases in both 2020 and 2021 was lower than that in 2019, and the difference was statistically significant ( χ2=4.054, P<0.05; χ2=8.109, P<0.05).There was no statistically significant difference in the proportion of bronchiolitis cases requiring ICU treatment between 2019, 2020, and 2021 ( χ2=1.914, P>0.05).In 2019, a total of 52.60%(2 582/4 909) of children with bronchiolitis underwent RSV pathogen testing, and among them, there were 708 cases with RSV positive, accounting for 28.00%.In 2020, 54.14%(1 437/2 654) of children with bronchiolitis underwent RSV pathogen testing, and there were 403 cases with RSV positive, accounting for 28.04%.In 2021, 66.80%(2 238/3 500) of children with bronchiolitis underwent RSV pathogen testing, and there were 935 cases with RSV positive, accounting for 41.78%.Compared with 2019 and 2020, the RSV positive rate in 2021 showed a significant increase( χ2=99.673, P<0.05; χ2=71.292, P<0.05). Conclusion:During the COVID-19 epidemic, the implementation of epidemic prevention and control measures reduced the hospitalization rate and severity of bronchiolitis, but did not reduce the positive rate of RSV detection.

Objective:To investigate the changes of various cytokines and coagulation function in B cell acute lymphoblastic leukemia(ALL) patients with different CRS scores during CD19-CAR-T cell immunotherapy.Methods:87 patients with B-ALL hospitalized in the First Affiliated Hospital of Soochow University and 30 normal controls were enrolled into this study from July 2018 to October 2020. The age of the patients was 32(20, 56) years old and 36(41.4%) were female. All these coagulation indicators, prothrombin time (PT), activated partial thromboplastin time (APTT), D-dimer, fibrinogen (Fg) were analyzed by automatic blood coagulation in B-ALL patients before and after treated with CAR-T cell. The ratio of CD19-CAR-T cells and the expression of IL-6, IL-10, IFN-γ, TFN-α, IL-2, IL-4, and IL-17A were analyzed using flow cytometry. The patients′ clinical parameters were detected, and the CRS classification of severity was made according to the standard of consensus.Results:Patients with CRS>3 had prolonged PT and APTT, increased D-dimer, and decreased fibrinogen ( P<0.05). The levels of cytokines of IFN-γ, IL-6, and IL-10 were significantly higher in patients with CRS>3 than that in controls ( P<0.05).The D-dimer level is positively correlated with IL-10. Conclusion:Patients with severe CRS grading have significant coagulation dysfunction in CD19-CAR-T cell immunotherapy. Cytokines IFN-γ, IL-6, and IL-10 may affect coagulation function and CRS grading during CD19-CAR-T cell immunotherapy.

Objective:To explore the research hotspots and trends of risk prediction models in nursing at home and abroad.Methods:The visual analysis software CiteSpace was used, and the Web of Science was used as the data source. The publication situation of the risk prediction model in nursing was visually analyzed, mainly including time distribution, country/research institution cooperation network, journal collinear network, co-citation, keywords and emerging words.Results:A total of 684 articles were included. The number of publications on the risk prediction in nursing was on the rise. The United States was the country that contributed the most to the number of publications, and China ranked second. The Journal of Advanced Nursing was the most published journal. In terms of institutions and authors, the cooperation was not close. Research hotspots mainly focused on pressure injuries, falls, and nurses' burnout. Adverse event prediction, patient prognosis and intelligent data mining were the key research directions. Conclusions:Compared with international ones, the research on nursing risk prediction in China still needs to be strengthened. Future research can broaden the direction, perfect the existing model and carry out verification and improvement, so as to provide a good reference for nursing work.

Objective:Factors influencing the prognosis of hemophagocytic lymphohistiocytosis (HLH) in adults were analyzed based on multicentric data.Methods:Clinical data of 124 adult patients with HLH diagnosed in eight medical centers in the Huaihai Lymphoma Working Group from March 2014 to July 2020 were collected. The optimal truncation value of continuous variables was obtained based on the Maxstat algorithm, X-Tile software, and restricted cubic spline. Cox proportional risk regression model was used to construct the adult HLH risk prediction model, and the visualization of the model was realized through the histogram. The bootstrap resampling method was used to verify the model, C-index and calibration curve was used to verify the histogram, and the prediction accuracy was checked. Kaplan-Meier analysis was used to calculate the survival rate and draw the survival curve. Furthermore, the differences between groups were tested by log-rank.Results:The median age of the 124 patients was 55 (18-84) years, including 61 (49.19%) males. The most common etiology was infection. Serum ferritin increased in 110 cases (88.71%) , hepatosplenomegaly in 57 cases (45.97%) . Of the 124 patients, 77 (62.10%) died, and the median survival time of the patients was 7.07 months. Univariate results showed that the prognosis of adult HLH was influenced by sex, age, fibrinogen, serum creatinine, alanine aminotransferase, and albumin ( P<0.05) . The results of multivariate analysis showed that gender, platelet, albumin, alanine aminotransferase, and treatment regimens were independent influencing factors for prognosis. Based on the above five risk factors, the prediction model of the histogram was established, and the C-index of the model was 0.739. Finally, the calibration chart showed good consistency between the observed and predicted values of HLH. Conclusion:The prognosis of the adult hemophagocytic syndrome is influenced by many factors. Gender, platelet, albumin, alanine aminotransferase, and treatment regimens are independent risk factors. Therefore, the established histogram provides a visual tool for clinicians to evaluate the prognosis of adult HLH.

Objective: To investigate the efficacy and safety of rapamycin in children with tuberous sclerosis complex (TSC) associated renal disease. Methods: A prospective self-control study was conducted. The clinical data of 92 children diagnosed with tuberous sclerosis complex associated kidney disease at the People′s Liberation Army General Hospital from January 2011 to January 2019 were collected. The long-term rapamycin treatment for all patients initiated at 1 mg/(m²·d), which was gradually adjusted to reach a blood concentration of 5-10 μg/L. The changes of the maximum diameter of renal lesions in children after rapamycin treatment were observed and analyzed with Wilcoxon test. Results: Ninety-two children, including 52 males and 40 females, who met the criteria were analyzed. Sixty patients had only renal angiomyolipoma(RAML), while 24 patients had only multiple renal cysts(MRC), and 8 patients had both lesions. The age of TSC diagnosis was 16.0 (7.0, 42.0) months, and the age of initial treatment with rapamycin was 63.5 (21.0, 103.0) months. The follow-up lasted for 12.0 (4.0, 23.0) months. Sequencing of TSC1 and TSC2 genes was performed in 54 children with TSC, including 3 patients (6%) with mutations in TSC1 gene and 51 patients (94%) with mutations in TSC2 gene. The maximum RAML diameter before treatment was 7.0 (4.0, 9.0) mm. The best effect reached at 3 months of treatment, with the diameter of 4.0 (0,7.0) mm. The maximum diameters at 6 months, 1 year and 1-2 years were 5.0 (0,9.8) mm, 5.0 (1.5, 8.5) mm, 5.5 (3.0, 9.0) mm, respectively, and were significantly different from the baseline (Z=-2.404,-2.350,-2.750,P=0.016,0.019,0.006, respectively). The maximum diameter after 2-3 years, and ≥3 years were 5.0 (3.9,7.0) mm and 6.0 (1.0, 11.0) mm, without significant difference from the baseline (Z=-0.856,-0.102,P=0.393,0.919, respectively).The maximum diameters of MRC after 3 months, 6 months, 1 year,1-2 years, 2-3 years, and ≥3 years were 11.0 (5.0, 14.0) mm,3.0 (0.0,11.0) mm,5.0 (0,21.0) mm,0 (0,14.0) mm,0 (0,10.0) mm, and 0 (0,18.3) mm, respectively, but were not significantly different rom the baseline (7.0 (5.0, 15.7) mm)(Z=-0.944,-1.214,-1.035,-1.896,-1.603,-1.214,P=0.345,0.225,0.301,0.058,0.109,0.225, respectively).Twenty-nine patients (32%) had oral ulcers during the entire treatment period, and no serious adverse reactions were observed. Conclusions Rapamycin could decrease the diameter of TSC-related RAML, but could not inhibit the growth of cysts. It is well tolerated in the treatment of renal diseases associated with tuberous sclerosis complex.

Antimicrobial resistance is on the rise while the number of antibiotics being brought to market continues to drop. Drug-resistant genes and drug-resistant bacteria infection have seriously threatened human health. Therefore, antimicrobial resistance presents an ongoing challenge that requires multifaceted approaches including: biomedical innovation; improved surveillance of antibiotic consumption and antimicrobial resistance generated rates; prevention of health-care-associated infections and transmission of multidrug-resistant bacteria and environmental dissemination; rapid microbiological diagnosis; and curtailed clinical and veterinary misuse. Fortunately, combating antimicrobial resistance has been highly valued and supported by the government, scientists and entrepreneurs of various countries. With the continuous introduction of new technologies, new products, and new management measures, the problem of antimicrobial resistance must be controlled and alleviated.

Objective To explore the influence of organizational safety atmosphere on work enthusiasm among junior nurses in ICU,so as to provide reference for improving job engagement and work quality of junior nurses in ICU. Methods In December 2016,213 junior nurses in ICU from 12 comprehensive class Ⅲhospitals in Nanning,Guilin and Liuzhou in Guangxi were selected and surveyed by the Safety Organizing Scale(Chinese version)and Questionnaire on Work Enthusiasm Appraisal. Influence of organizational safety atmosphere perceived by junior nurses in ICU on their work enthusiasm was analyzed. Results For the junior nurses in ICU,scores of safety organizing were(38.60±7.12)points,and scores of work enthusiasm were (57.04±8.23);differences of junior nurses' work enthusiasm scores under different organizational safety atmosphere were statistically significant(F=10.908,P< 0.001). Work enthusiasm and its dimensions were positively related to organizational safety atmosphere(P<0.05). Conclusions The more safety organizing investment is,the higher work enthusiasm is of junior nurses in ICU.

OBJECTIVE: To determine whether the composite acoustic therapy is effective to treat tinnitus in patients with sudden deafness and to explore the mechanisms. METHOD: Ninety-six cases (96 ears) were divided into experimental group and control group, and all the patients underwent drug treatment. The patients in experimental group were given personalized composite acoustic therapy in the first 30 days, music therapy in next 31-90 days, however, the patients in control group were not given sound therapy. Additionally, pure tone audiogram, tinnitus pitch and loudness as well as questionnaires (including THI, VAS, and SAS) were conducted for each patient before treatment, at day 30 and day 90 posttreatment. RESULT: Eighty-nine patients (n = 47 for experimental group and n = 42 for control group) completed the trial. The results of day 30 posttreatment showed there were no significant differences in VAS and hearing recovery rate between these two groups, but THI and SAS showed significant differences. The results of day 90 posttreatment showed significant differences in VAS (P < 0.05), THI (P < 0.01) and SAS (P < 0.01), and no significant difference of hearing recovery rate was detected. The most significant changes of VAS appeared in the first 30 days of treatment. The hearing and tinnitus recovery in experimental group were better for the first 30 days of treatment than for the next 31-90 days, and similar results were obtaind in control group. (P < 0.01). CONCLUSION Composite acoustic treatment combined with drug therapy can improve the tinnitus and anxiety symptoms of patients with sudden deafness, and the effect on hearing recovery still need to be confirmed in further studies.
