Evidence mapping is a novel method of evidence synthesis that has been increasingly applied in the field of TCM in recent years. This article provided a comprehensive and detailed introduction to the origin, definition, and characteristics of evidence mapping. It systemically reviewed and summarized published studies on evidence mapping in TCM, exploring common issues encountered during the production and reporting of TCM evidence mapping research. Such issues included the failure to highlight the advantages of TCM in the research topic, lack of prior registration of the study, limited scope of searches, unclear inclusion and exclusion criteria, insufficient standardization in literature screening and data extraction, inadequate overall quality assessment, obscure process of evidence synthesis, lack of targeted evidence analysis, and insufficiently standardized reporting of results. Corresponding improvement strategies were proposed to enhance the quality of TCM evidence mapping literature, increase the reliability and applicability of research outcomes, and thereby promote the modernization and internationalizati.

Objective:To explore the mechanism of pterostilbene(PTE)in preventing and treating neuroinflamma-tion after cerebral ischemia-reperfusion injury(CIRI)in rats.Methods:Ninety male SD rats were randomly divided in-to a sham group,a model group(MCAO/R),a low-dose PTE group(PTE-L),a medium-dose PTE group(PTE-M),and a high-dose PTE group(PTE-H).CIRI model was prepared by middle cerebral artery occlusion reperfusion(MCAO/R)in rats.The neurological deficit in rats was evaluated by Zea Longa score.The volume of cerebral infarc-tion was detected by TTC staining.The morphological changes of ischemic cortex was observed HE staining.The ex-pressions of cyclooxygenase-2(COX-2),prostaglandin D2 receptor(DP2)and prostaglandin D1 receptor(DP1)were detected by RT-qPCR and Western Blot.The expressions of prostaglandin D2(PGD2),interleukin-1 β(IL-1β)and tumor necrosis factor-α(TNF-α)were detected by ELISA.Results:Compared with the sham group,the MCAO/R group showed a significant increase in neurological scores(P＜0.05),a significant increase in cerebral infarction vol-ume(P＜0.05),and aggravated cortical damage in the ischemic area.Additionally,there were significant increase in the expressions of COX-2,DP2 mRNA and protein(P＜0.05),along with increased expressions of PGD2,IL-1β and TNF-α(P＜0.05).Compared with the MCAO/R group,the PTE-L,PTE-M,and PTE-H groups showed a significant decrease in neurological scores(P＜0.05),a significant decrease in cerebral infarction volume(P＜0.05),and markedly alleviated cortical damage in the ischemic region.Additionally,there were significant decrease in the expres-sions of COX-2,DP2 mRNA and protein(P＜0.05),along with decreased expressions of PGD2,IL-1β and TNF-α(P＜0.05).Furthermore,a dose-effect relationship was observed for the neuroprotective effects of PTE on brain tissue(P＜0.05).However,there were no significant differences in the expressions of DP,mRNA and protein among all groups(P＞0.05).Conclusion:PTE can attenuate the neuroinflammation of CIRI in rats by inhibiting COX-2/PGD2/DP2 signaling pathway.
