Research progress of natural collagen peptides and its skincare efficacy / 生物医学工程学杂志

Natural collagen peptides are collagen hydrolysates. Because of their unique physicochemical properties and excellent biological activities, collagen peptides have been a research hotspot of cosmetic raw materials development and skincare efficacy improvement. Combined with the needs of the skincare efficacy and the development trends of cosmetics, the extraction methods and their structural characteristics of natural collagen peptides were summarized in detail. The applications and its research progress in skincare efficacy of collagen peptides, such as moisturizing and anti-wrinkle, trophism and anti-aging, filling and skin regeneration were expressed with emphasis. Finally, the development and practical applications in cosmetics of natural collagen peptides were adequately prospected.

Effect of collaborative nursing on the quality of life and care ability of stroke patients / 现代临床护理

Objective To explore the effect of collaborative nursing on the quality of life and nursing of stroke patients. Methods Toally 84 care-givers for 84 stroke patients hospitalized during February 2014 to March 2016 were chosen. In the control group(hospitalized from Feburary 2013 to Feburary 2014), traditional nursing was carried out, while in the research group(hospitalized from March 2014 to March 2016), the collaborative care intervention was done. The comparisons were done between the two groups in terms of quality of life and care ability by the GHQ-28 quality of life scale assessment, family caregiver task inventory (FCTI) before the intervention and 4 weeks after the intervention. Results Before the intervention, the two groups had no significant differences in life quality and care ability (all P > 0.05). After the intervention, the scores on symptoms, anxiety, depression, insomnia and social dysfunction were all significantly higher than those of the control group (all P<0.05). The scores on the care role, strain, assistance, personal emotion control, family assessment and community resources, and adjustment of life to meet the care needs were all significantly lower than those of the control group (all P<0.05). Conclusions The collaborative care is effective in improving the quality of life of stroke patients. It can improve the care ability of the caregiver.
