The contents of the individual fractions of glucose oligosaccharides were determined simultaneously by means of reversed-phase HPLC. The sample was dissolved in water and filtered and the filtrate was used directly for the analysis. The sugar was separated on a column of u-Bondapak C18 using water as the mobile phase and determined refractometrically.The method was applicable to the analysis of glucose oligosaccharides from monomeric glucose through polymeric maltooctose. Quantitative results were obtained for glucose, maltose, maltotriose, maltotetrose, maltopentose and maltohexose in the samples prepared in our laboratory. Recovery tests revealed this method reliable.

The effects of grape seed oil on serum total cholesterol (TC) and high density lipoprotein cholesterol (HDL-C) levels were investigated in experimental hypercholesterolemic rats. The grape seed oil containing about 74% linoleic acid, multivitamins and trace elements. Each animal was given 4 ml/kg BW grape seed oil mixed in high fat ration for 40 days. The results in two experiments showed that TC concentration in the serum of rats fed grape seed oil was markedly lowered as compared to control, but serum HDL-C was less lowered. Furthermore, the ratio of HDL-C to TC in the experimental group was also significantly higher than that of control.

ObjectiveTo systematically evaluate the effect of art therapy on the mental health of older adults with mild cognitive impairment (MCI), based on International Classification of Functioning, Disability and Health. MethodsLiterature on art therapy for mental health of MCI older adults was retrieved from databases of CNKI, VIP, Wanfang Data, PubMed, ProQuest and Web of Science, between 2014 and 2024, and selected according to inclusion and exclusion criteria. The quality of the literature was assessed using PEDro scale, and a systematic review was conducted following the PRISMA guideline. ResultsA total of nine researches were included from China, Tanzania, Spain, Malaysia and Singapore, involving 763 individuals with MCI aged 60 or more (average 71.23). The types of art therapy interventions were visual arts therapy (painting, collage, paper-cutting, sculpture and modeling, etc.), expressive arts therapy (encompassing dance and music) and creative arts therapy (narrative creation), 30 to 120 minutes a time (majority of 60 minutes), one to four times a week (majority of two to four times), for six to 36 weeks (majority of six to twelve weeks). Health outcomes predominantly focused on mental health, such as anxiety and depression. ConclusionMost researches support that art therapy is effective on mental health of older adults with MCI, but there are disagreements in some researches, and more researches are needed.
