This paper gives a report on a new species of paragonimus in MT.Wuyishan,Fujian province during 1978 to 1983.All the type are deposited in the Center for Disease Control and Prevention of Fujian province.Holotype body short-oval,12.5 by 7.0mm,ratio of width to length 1:1.79.Ovary 2.0×2.13mm in size,the third class branches.Testes big,2.5 by 3.75mm(left) and 2.0 by 4.75mm(right)in size,as piece-shapy,only 2 litter branches,being much larger than the ovary.cuticular spines slender,sing in arrangement.Matacercaria obtained from the fresh-water crab,Sinopotamon fujianensis Dai et Chen,1979,measuring 395 by 410 micra,its cyst wall sing ,only 3-5 micra.Basing on the characteristic features mentioned above,This worm found by us differs fromP.westermani,P.skrijabini,P.macrorchis,P.mingqingensis and Euparagonimus cenopiosus,and can be considered as a new species of Paragonimus.

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.
