Monoclonal antibodies(mAbs)to human TRAIL receptors(TRAIL-Rs)have been developed in tumor targeted therapy and currently used in clinical Ⅰ~Ⅳtrials.MAbs can bind death-receptors(TRAIL-R1 and TRAIL-R2)and then results in formation of the death inducing signaling complex (DISC)and apoptosis of tumor cells.TRAIL -Rs mAbs have become one of the research and development hotspots of anti -tumor drugs.These mAbs have achieved remarkable results in combination with radio -or chemo-therapy drugs or oth-er agents and immunotherapy in the treatment of tumor and offer a new therapeutic strategy for clinical tumor treatment.

Objective:To investigate the clinical effect of hearing aid combined with cognitive rehabilitation training in the treatment of dementia with hearing loss.Methods:Forty-six cases of dementia patients with hearing loss in Dalian Municipal Central Hospital Affiliated of Dalian Medical University from September 2019 to September 2020 were divided into two groups by random number table method. The treatment group received cognitive rehabilitation training assisted by sound amplifier, while the control group only received cognitive rehabilitation training for 7 weeks. Before and after treatment, questionnaires were used to evaluate the training effect of patients, including MMSE, HAMA, HAMD and ADL, and satisfaction questionnaire was used to evaluate the satisfaction of caregivers.Results:After treatment, the MMSE score of the treatment group was significantly higher than that of the control group: (20.22 ± 3.38) scores vs. (19.89 ± 3.10) scores ( P<0.05), and HAMA and HAMD were significantly lower than those of the control group: (11.43 ± 5.07) scores vs. (11.83 ± 4.79) scores, (8.39±3.37) scores vs. (9.67 ± 5.34) scores ( P<0.05); there was no difference in activities of daily living between the treatment group and the control group ( P>0.05); the caregiver satisfaction of the treatment group was significantly improved, compared with that of the control group ( P<0.05). Conclusions:Hearing assisted cognitive training can improve the cognitive function of patients with hearing-impaired dementia, promote mental and emotional stability, and improve the feelings of caregivers; we emphasize the importance of hearing evaluation for the elderly with dementia, and the importance of cognitive rehabilitation training with hearing assistance.
