ABSTRACT
Objective:To evaluate the diagnostic accuracy and clinical applicability of the Simple Five item Scoring Scale for Sarcopenia (SARC-F) by systematic review and Meta-analysis.Methods:PubMed, The Cochrane Library, Wed of science, EMBASE, MEDLINE, Ovid, China HowNet database, China biomedical data, VIP database and Wanfang database were searched by computer, and all the researches related to SARC-F questionnaire's diagnosis of sarcopenia from the establishment of the database to March 1, 2020 were collected. Two researchers independently selected literature, extracted data, and evaluated the bias risk of the study. Revman 5.3 software, Stata16.0software were used to comprehensively evaluate the diagnostic value of SARC-F questionnaire for sarcopenia.Results:A total of 13 studies involving 8 860 patients were included. The results of meta-analysis showed that the sensitivity and specificity of the diagnostic criteria established by the European Working Group of Sarcopenia, the Asian Working Group for Sarcopenia and the International Working Group for Sarcopenia were used as the gold standard. The area under the receiver operating characteristic curve was 0.71, 0.69 and 0.67 respectively, and the Q-index was 0.659 3, 0.650 9 and 0.631 6.Conclusion:SARC-F questionnaire has a certain value in the screening and diagnosis of sarcopenia. In the future research, it is suggested to add the simple measurement of muscle quality on the basis of this scale to improve the accuracy of the questionnaire screening
ABSTRACT
Object To study the hydroxyl radical scavenging and DNA damage protecting activities of 5 Uighur herbal medicines Euphorbia humifusa Willd , Borago officinalis L, Cassia angustifolia Vahl, Terminalia chebula Retz. and Fomes officinalis (Vill ex Fr ) Bres Methods The hydroxyl radical scavenging action and DNA damage protection action were determined by CuSO 4 Vit C H 2O 2 yeast and CuSO 4 Vit C H 2O 2 phen DNA chemiluminescence systems respectively Results All 5 Uighur medicinal herbs showed hydroxyl radical scavenging and DNA damage protection activities in dose dependent manners Conculsion The hydroxyl radical scavenging and DNA protective effects may possibly be the mechanisms of their antiaging and therapeutic effects against various diseases
