Icariin（ICA） is one of the main active ingredients in the Berberidaceae family Epimedium. It makes a variety of biological activities, such as promoting bone formation, antibacterial and anti-inflammatory, and regulating immunity. Periodontitis is a chronic inflammatory disease that is present in the soft and hard tissues of the periodontium. The ultimate goals of its treatment are the reconstruction of periodontal tissues and bone defect repairing. At present, conventional treatment of periodontitis fails to achieve the ideal periodontal tissue regeneration. In recent years, the rapid development of tissue engineering technology has brought new ideas for the treatment of periodontal disease and bone defect repairing. Because of its anti-inflammatory and osteogenic effects, ICA has great potential for the treatments of periodontitis and bone defect repairing. This paper summarizes the effect and the molecular mechanism of ICA in the treatment of periodontitis and bone defect repairing, and discusses its application prospect as a drug for periodontal adjuvant therapy. This paper aims to provide a theoretical basis for the research and application of ICA in periodontitis treatment and bone defect repairing.
ObjectiveTo evaluate the efficacy of different non-pharmacological interventions on cognitive function in elderly patients with mild cognitive impairment by the network meta-analysis. MethodsThe PubMed, Embase, Cochrane Library, CINAHL, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect randomized controlled trials (RCTs) related to the objectives from inception to November 2022. Two reviewers independently screened literature, extracted data and assessed the risk of bias of the included studies. The network meta-analysis was then performed by using Stata 16.0 and Open BUGS 3.2.3 software. ResultsA total of 43 RCTs involving 2 986 patients were included, which involved 8 non-drug intervention methods. The best probability ranking results of the network meta-analysis showed that on the simple mental state scale (MMSE) scores: rTMS > acupressure > acupuncture therapy > exercise therapy > cognitive training > multicomponent intervention > VR > conventional care > health education, and on the Montreal cognitive assessment scale (MoCA) scores: VR > exercise therapy > rTMS > acupuncture therapy > acupressure > cognitive training > health education > conventional care. Conclusion Current evidence shows that rTMS, acupressure, VR, exercise therapy and acupuncture may be effective interventions to improve cognitive function in elderly patients with mild cognitive impairment. Due to the limited quality and quantity of the included studies, more high quality studies are needed to verify the above conclusion.
The essence of ensuring universal nutritional health lies in achieving a balance between the growing demand for nutritional health and the supply of adequate and balanced nutritional services. This paper learns and draws on the ideological theory and methodological support of evidence-based science, optimizing practices, reevaluations, monitoring risks, producing evidence and cultivating talents so as to enable the interdisciplines of evidence-based nutrition and develop in a localized way and gain optimal timeliness, quantity and quality.
