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.

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 (

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: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.
