ABSTRACT
Objective To study the memory disorder perception characteristics of subjective memo-ry complaints(SMCs)and to analyze the influencing factors. Methods 302 subjects conforming to the in-clusion criteria were selected.All the subjects completed the illness perception questionnaire-memory of Chi-nese version(IPQ-M). Results (1)There was no statistical difference between the score of social compari-son(2.95±0.78)and the middle value 3.The differences between the score of the remaining dimensions of memory impairment perception(timeline acute/chronic(3.57 ± 0.89),consequences(2.24 ± 0.77),timeline stability/decline(3.71±0.88),personal control(blame)(3.61±0.92),personal control(helplessness)(3.31± 0.73),emotional representation(2.29 ± 0.70),treatment control(2.78 ± 0.67),illness coherence(3.14 ± 0.64))and the middle value 3 were statistically significant(all P<0.05).(2)Gender,education level,living condition,marital status,economic condition,family history of dementia and knowledge education of dementia were the influencing factors of memory perception of SMCs. Conclusion The memory complaining people are less aware of the related knowledge of memory decline,and there are more errors and negative percep-tions.The factors that affect the perception of memory disorders are complex.
ABSTRACT
Objective@#To study the different expression of 4 microRNA (miRNA, miR) during the osteogenesis differentiation of bone marrow mesenchymal stem cell (BMSC) cultured in high-fat or normal environment and to explore the relationship of these miRNAs with disheveled 2 during osteogenesis differentiation.@*Methods@#BMSC were cultured with 2 ml normal osteogenic induction (control group) and high-fat osteogenic induction (high-fat group) respectively. On the 3rd, 5th, 7th,14th, 21st day, quantitative real-time PCR (qPCR) was used to analyze expression levels of four miRNAs (miR-21-5p, miR-29c-3p, miR-138-5p and miR-351-5p), mRNA of disheveled 2, osteogenic related factors such as alkaline phosphatase (ALP), Runt-related transcription gene 2 (Runx2). And the protein was detected by Western blotting. After BMSC were transfected by 50 μl 50 nmol/L miRNA mimics/inhibitors/negative controls respectively, BMSC were put on osteogenic induction, on the 1st, 3rd, 5th, 7th day, ALP activity was detected. On the 7th day, ALP staining was to observe the degree of osteogenesis differentiation, and Western blotting was adopted to analyze the expression of dishevelled 2 and other osteogenic related factors, while qPCR was used to analyze the expression of disheveled 2 mRNA. After 293T cells were co-transfected with disheveled 2 wild-type/mutant firefly luciferase reporter plasmid with either negative control (NC) or a mimic of these four miRNAs respectively for 48 h, luciferase activities were measured.@*Results@#On the 21th day, the expressions of miR-21-5p, miR-29c-3p, miR-138-5p and miR-351-5p in high-fat groups were higher by 20%, 60%, 340% and 4 420% respectively than those in control groups (P<0.05). The expression of ALP and Runx2 in BMSC decreased after BMSC transfected miR-21-5p and miR-29c-3p mimics, while increased after transfected miR-21-5p and miR-29c-3p inhibitors. The expression of disheveled 2 decreased by 35% after transfected by miR-29c-3p mimic, while it increased by 269% after transfected by miR-29c-3p inhibitor (P<0.05). Transfection of the miR-29c-3p mimics significantly decreased the luciferase activity of wild-type 3'-UTR compared with NC control (P<0.05). There were no statistical significances among other groups.@*Conclusions@#miRNAs had better expression during osteogenesis differentiation of BMSC in high-fat environment; miR-29c-3p could negatively regulate the osteogenesis differentiation of BMSC by targets on dishevelled 2.
ABSTRACT
Objective To introduce the illness perception questionnaire-memory (IPQ-M) and translate it into Chinese and to evaluate its reliability and validity.Methods The Chinese version of IPQ-M was translated from the original,back translated and adjusted for culture adaptation.A total of 152 community-dwelling people with subjective memory complaints (SMCs),who were aged 50 years or above,were investigated with the Chinese version of IPQ-M.40 participants among them were re-evaluated 2 weeks later.Results Exploratory factor analysis got 9 factors which could explain 70.757％ of the total variance.The factor loading of each item on the corresponding factors was higher than 0.4.The correlation between Chinese version of IPQ-M and GDS were-0.208 to 0.763 (P＜0.01).The Cronbach's α coefficient was 0.872,the testretest reliability was 0.894,and the Spearman-Brown split coefficient was 0.890.Conclusion The Chinese version of IPQ-M has good reliability and validity,and it can be used in Chinese elderly people with SMCs.
ABSTRACT
Objective To investigate the characteristics of everyday memory of adults with subjective memory complaints (SMC),and probe into the correlation between everyday memory function and life quality.Methods Through convenience sampling,150 adults with SMC were face-to-face interviewed by an investigator,with demographic characteristics collected,and the cognition function,everyday memory function and life quality were also assessed during the interview.Results Among the 150 adults with SMC,the impairment rate of everyday memory function reached 96％,and the median score of RBMT-II was 16.00 (interquartile range 6.00),indicating a low level of everyday memory function,with the Name andDelayed recall Story items having lower scores.All participants were divided into two groups according to cognitive status,with 67 (44.70％) adults having normal cognitive function and 83 (55.30％) impaired cognitive function.After comparison,significant differences were found in the total score of RBMT-II and scores ofFaces recognition andDelayed recall Story between the two groups (P＜0.05).In all dimensions of SF-36,the median score of general health dimension for the 150 adults was 55.00 (inter-quartile range 31.25).The Spearman rank correlation analysis showed that the scores of several dimensions in RBMT-II were positively correlated with the scores of several dimensions in SF-36 (P＜0.05).Conclusion Everyday memory function of people with SMC was positively CorTelated with their life quality.
ABSTRACT
Objective To explore the impact of patients with esophageal cancer knowing diagnosis on the mental health of their children and investigate the factors.Methods 107 family carriers whose parent diagnosed esophageal cancer in General Hospital of Jinan Command were interviewed.Respondents were categorized into two groups:one group was those whose parents knew their diagnosis(Group A,n=45)and the other group was those whose parents did not know(Group B,n=62).The Chinese version of Self-reporting Inventory(SCL-90) was used.Results The scores of 107 children of esophageal cancer patients in depression(1.62±0.30),anxiety(1.78±0.34) and hostility (1.93±0.47) were higher than national norms (P＜0.01).Compared with group A,group B showed a significant higher degree of anxiety((1.89±0.33) vs (1.62±0.33),P＜0.01).In multiple regression analysis,age and the knowledge of esophageal cancer diagnosis had statistically significant difference (P＜ 0.05).Conclusion Patients' knowledge of the esophageal cancer diagnosis contribute to relieving family carers' symptoms of anxiety.
