Objective:To explore the current situation of the intrinsic capacity of elderly people in the community and analyze its influencing factors.Methods:From September 2022 to March 2023, convenience sampling was used to select 360 elderly community residents from Xicheng District, Beijing, and Xingtai City, Hebei Province, as the research subjects. The subjects were surveyed using the Intrinsic Capacity Assessment Questionnaire, Intrinsic Capacity Influencing Factors Questionnaire, Barthel Index, and Lawton Instrumental Activities of Daily Living Scale.Results:A total of 360 questionnaires were distributed, and 360 valid questionnaires were collected, with an effective response rate of 100.0% (360/360). The overall impairment rate of intrinsic capacity among 360 elderly people in the community was 90.3% (325/360), and the impairment rates in various fields from high to low were sensation, psychology, vitality, cognition, and exercise. Multiple linear regression analysis showed that age, gender, residential pattern, education level, work status, grip strength, number of geriatric syndrome, self-rated health status, adverse life events, number of social activities, transportation conditions, and social security were the influencing factors of the intrinsic capacity of elderly people in the community, and the difference was statistically significant ( P<0.05) . Conclusions:The impairment rate of intrinsic capacity among elderly people in the community is relatively high. Grassroots medical and nursing staff should assess the intrinsic capacity of elderly people in the community in health promotion work, identify elderly people with decreased intrinsic capacity early and carry out effective interventions to prevent elderly people from becoming disabled and dependent on care.

Objective:To conduct a scoping review on the impact of community environment on the health of older adults from the perspective of person-environment fit, so as to provide reference for the creation of targeted care environments and the construction of elderly friendly communities.Methods:Literature on the impact of community environment on the health of older adults from the perspective of person-environment fit was searched on China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc, PubMed, Embase, Web of Science, Cochrane Library, Scopus, CINAHL, PsycInfo and so on. The search period was from database establishment to December 31, 2023. Literature was screened and data was extracted based on inclusion criteria.Results:A total of 19 articles were included, and the methods of person-environment fit included compensation and consistency. Sixteen articles described how community environment promoted the health of older adults by compensating for the decline in individual abilities and socio-economic disadvantages of older adults. The poorer the individual abilities and lower the socio-economic status of older adults, the greater the impact of environmental factors. Three articles mentioned that the consistency between community environment and the needs of older adults could promote their health.Conclusions:The interaction between the individual characteristics of older adults and their surrounding environmental resources determines their health status. When building elderly friendly communities and providing care environments, consideration should be given to the individual abilities and needs of older adults, and the impact mechanism of the environment on the health of older adults can be explored from multiple perspectives.

Objective:To carry out a scoping review of research related to the use of virtual reality technology in geriatric nursing.Methods:Guided by the scoping review framework proposed by Arksey and O'Malley, Chinese and English literature on the effect of virtual reality technology in geriatric nursing was systematically searched on databases such as China National Knowledge Infrastructure, WanFang Data, VIP, China Biology Medicine disc, PubMed, Web of Science, Cochrane Library, EBSCO, Embase and so on. The search period was from database establishment to July 1, 2023. Two researchers independently screened literature, extracted data, and summarized the content of the literature.Results:A total of 35 articles were included. The research mainly involved the impact of virtual reality technology on the cognitive function, physical function, psychological state, symptom relief, health management, and teaching effectiveness of geriatric nursing. Among them, 27 articles indicated that virtual reality technology had positive effects, while 8 articles did not clarify the advantages and differences between virtual reality technology and traditional methods.Conclusions:Virtual reality technology has development potential in geriatric nursing, but virtual device intervention may cause discomfort symptoms such as dizziness and vomiting in the elderly, and is influenced by individual digital literacy. Research should focus on improving the comfort of using the equipment and enriching its usage scenarios.

OBJECTIVETo establish a method for the determination of 5-hydroxy-7-methoxyflavan in Daemrnonorops draco by HPLC.

METHODDikma Diamonsil C15 column(4. 6 mm x 150 mm, 5 microm) was used. The mobile phase consisted of (60:40). The temperature of column was 30 degrees C. The flow rate was 1:0 mL x min(-1) and the detection wavelength was at 210 nm.

RESULTThe calibration curve was in good linearity with in the range from 0.01 to 0.10 microg (r = 0.9999). The average recovery was 100.1% (n=6).

CONCLUSIONThe method is simple, rapid, as well as precise and reliable, and can be used for the determination of 5-hydroxy-7-methoxyflavan in D. draco.
