ABSTRACT

Objective:To explore any effects of combining virtual reality training with aromatherapy in caring for Alzheimer′s disease patients in a nursing home.Methods:Fifty nursing home residents with Alzheimer′s were divided at random into an observation group and a control group, each of 25. Both groups received routine rehabilitation, while the observation group was additionally given 45 minutes of virtual reality training combined with aromatherapy, 3 times a week for 6 months. Both groups′ cognition was then evaluated using the MMSE and an Alzheimer′s cognition assessment scale (ADAS-cog). Psycho-behavioral symptoms were quantified using the Alzheimer′s disease pathological behavior scale (BEHAVE-AD). Motor functioning was quantified using the timed up and go test (TUGT), the 30-second sit-to-stand test (30sCST), the 30-second arm curl test (30sACT) and the sit-and-reach test (CSRT). Ability in the activities of daily living (ADL) and life quality were quantified using the activity of daily living scale and of the quality of life scale for Alzheimer′s disease (QOL-AD) before and after the intervention.Results:After the intervention the average MMSE, ADAS-cog, BEHAVE-AD and ADL scores of both groups had improved significantly, with the average improvement in the observation group significantly greater than that in the control group. The TUGT, 30sCST, 30sACT and CSRT results of both groups were also significantly better, with those of the observation group again significantly superior, on average, to the control group′s results. The average QOL-AD score in the observation was significantly improved after the intervention, and was then significantly better than the control group′s average.Conclusions:Virtual reality training combined with aromatherapy can significantly improve the cognition, psycho-behavioral symptoms, activity in daily living, motor functioning and life quality of Alzheimer′s patients in a nursing home. It is worthy of promotion and application in nursing homes.

ABSTRACT

Objective:To observe any effect of virtual reality (VR) training on the cognitive functioning and functional fitness of nursing home residents with subjective cognitive decline (SCD).Methods:Fifty-six of such residents were randomly divided into an observation group and a control group, each of 28. Both groups received health education and routine care, but the observation group was additionally provided with 45 minutes of VR training three times a week for 6 months. The training included Baduanjin, magic, flying bird, supermarket shopping, gravity ball and gym episodes. Both groups′ cognition was evaluated using the subjective cognitive decline questionnaire (SCD-Q), the Montreal cognitive assessment (MoCA), the Rivermead Behavioural Memory Test (second edition) (RBMT-Ⅱ), a digit symbol substitution test (DSST), an animal fluency test (AFT) and trail-making test A-B (TMT A-B). Functional fitness was quantified using the 8-foot up-and-go test (8UGT), a 30-second arm curl test (30sACT), a 30-second chair stand test (30sCST), a back scratching test (BST), the sit-and-reach test (CSRT) and a 2-minute step test (2MST) before and after the 6-month intervention.Results:After the intervention, the average SCD-Q, MoCA, RBMT-Ⅱ, DSST, TMT-A, and TMT-B scores of the observation group were significantly better than before the intervention, and significantly better than the control group′s averages. And except for the back scratching their functional results were also significantly better, on average, than those of the control group.Conclusions:VR training can effectively improve the cognition and functional fitness of nur-sing home residents with SCD. Such training is worthy of promotion and wider application in nursing homes.

ABSTRACT

Objective:To explore the effect of virtual reality (VR)-based baduanjin exercise on the cognition, physical functioning and life quality of elderly persons with mild cognitive impairment (MCI).Methods:Fifty-seven mildly impaired elderly persons were randomly divided into an observation group ( n=29) and a control group ( n=28). Both groups were given routine care and health education in their nursing homes, while the observation group additionally performed 50 minutes of VR baduanjin exercise three times a week for 24 weeks. Both groups were assessed using the Montreal cognitive assessment (MoCA), the Rivermead behavioural memory test (second edition) (RBMT-Ⅱ), a digit-symbol substitution test (DSST) and the Trail Making Test (TMT). The short physical performance battery (SPPB) and Alzheimer′s disease quality of life (QOL-AD) instrument were also administered before and after the 24-week intervention. Results:After the intervention the average MoCA, RBMT-Ⅱ, DSST, TMT-A, SPPB and QOL-AD results of the observation group were all significantly better than before the intervention and better than the control group′s averages. The observation group also performed better on the 5 times sit-to-stand test, the tandem standing test and a walking speed test after the intervention.Conclusions:VR-based baduanjin practice can effectively improve the cognition and physical functioning of mildly impaired elderly persons, as well as improving their quality of life.

ABSTRACT

In the present study, total membrane proteins from tumor cell lines including HepG2, Hep3B2, H226, Ovcar3 and N87 were extracted and digested with LysC and trypsin. The resulting peptide lysate were pre-fractionated and subjected to untargeted quantitative proteomics analysis using a high resolution mass spectrometer. The mass spectra were processed by the MaxQuant and the protein abundances were estimated using total peak area (TPA) method. A total of 6037 proteins were identified, and the analysis resulted in the identification of 2647 membrane proteins. Of those, tumor antigens and absorption, metabolism, disposition and elimination (ADME) proteins including UDP-glucuronosyltransferase, cytochrome P450, solute carriers and ATP-binding cassette transporters were detected and disclosed significant variations among the cell lines. The principal component analysis was performed for the cluster of cell lines. The results demonstrated that H226 is closely related with N87, while Hep3B2 aligned with HepG2. The protein cluster of Ovcar3 was apart from that of other cell lines investigated. By providing for the first time quantitative untargeted proteomics analysis, the results delineated the expression profiles of membrane proteins. These findings provided a useful resource for selecting targets of choice for anticancer therapy through advancing data obtained from preclinical tumor cell line models to clinical outcomes.

ABSTRACT

Objective To observe any effect of low-frequency transcranial magnetic stimulation (rTMS) on the sleep and mood of elderly insomniacs.Methods Thirty-four elderly insomniacs were divided randomly into an experiment group (n =18) and a control group (n =16).The experiment group received rTMS of the right dorsolateral prefrontal cortex,while the control group was given alternating magnetic field stimulation at the same site.Before and after 4 weeks of the treatments,all of the subjects were assessed using the Pittsburgh sleep quality index (PSQI),the Hamilton anxiety scale (HAMA) and the Hamilton depression scale (HAMD).They were also assessed with those instruments omitting the sleep items in order to reduce the possible impact of any sleep changes on the HAMA and HAMD scores.Results Before the treatment there were no significant differences in the groups' average PSQI,HAMA and HAMD scores.After 4 weeks all the measurements in both groups had decreased significantly,with the experimental group's averages significantly lower than those of the control group.Conclusions rTMS treatment is more effective than alternating magnetic field treatment for the elderly with insomnia,significantly improving their sleep and mood.
