Objective:To conduct a scoping review of the related research on the maternal-fetal attachment in pregnant women after assisted reproductive technology (ART), summarize the research status of maternal-fetal attachment, and provide reference for future research prospects.Methods:A search was conducted for studies published in PubMed, Embase, EBSCO, Web of Science, Scopus, Cochrane Library, China National Knowledge Infrastructure, Wanfang, and Chinese Medical Journal Full-text Database, from the date of database construction to January 24, 2024. The results of the literature were screened, extracted, and summarized.Results:A total of 15 studies were included. Among them, 14 observational studies reported that the overall status of maternal-fetal attachment of ART pregnant women was in good condition, but the data sources of domestic research were insufficient. Three evaluation tools were used in 15 articles. The related factors were summarized as demographic factors (age and personality traits), pregnancy-related factors (such as conception method, gestational age, history of infertility, history of miscarriage, etc), and psychosocial factors (such as anxiety, depression, conflicts, attitudes towards childbirth, acceptance of pregnancy, social support, marital satisfaction, etc). Four studies put forward suggestions or conducted intervention studies on improving maternal-fetal attachment of ART pregnant women.Conclusions:There is a lack of attention to the maternal-fetal attachment of ART pregnant women in China. Due to the complexity and diversity of its influencing factors, we should deeply explore the characteristics of maternal-fetal attachment development of ART pregnant women at all stages of pregnancy, and carry out more high-quality research. At the same time, we should pay attention to and carry out early screening of maternal-fetal attachment disorders, formulate targeted interventions, so as to promote the establishment of high-quality maternal-fetal attachment, and lay a solid foundation for future maternal-infant relationships.

OBJ ECTIVE To predict the quality marker （Q-Marker）of Forsythia suspensa . METHODS The fingerprints of 10 batches of F. suspensa were established by high performance liquid chromatography. The common peaks were confirmed. The candidate components of Q-Marker in F. suspensa were screened. The volatile oil of F. suspensa were analyzed by gas chromatography-mass spectrometry （GC-MS），and the candidate components of Q-Marker in volatile oil were screened. The network pharmacology analysis was performed for the candidate components of Q-Marker. The network diagram of the “candidate components of F. suspensa Q-Marker-target-pathway”was constructed to predict the Q-marker of F. suspensa . RESULTS & CONCLUSIONS Twenty-one common peaks were obtained for 10 batches of F. suspensa ，and four components were identified as phillyrin，forsythoside A ，pinoresinol-4-O-β-D-glucoside and rutin. Seven candidate components were obtained by GC-MS analysis，such as β-pinene，α-pinene，terpinen-4-ol，limonene，γ-terpinene，α-phellandrene，β-myrcene. By network pharmacology analysis， 16 key targets and 17 pathways were obtained. It was preliminarily predicted that phillyrin ， forsythoside A ， pinoresinol-4-O-β-D-glucoside，rutin，terpinen-4-ol，α-phellandrene，α-pinene and β-pinene were Q-marker of F. suspensa .
