Objective:To understand trends and hotspots of TCM research papers published in journals with high IF basing on a bibliometric analysis.Methods:TCM research papers published between January 1, 2014 and December 31, 2024 from 80 journals with IF higher than 16.0 were retrieved from medical, life sciences and comprehensive journals in Journal Citation Reports of 2024. CiteSpace 6.3.R1 and Excel 2021 were used to analyze and visualize annual publication volume, research fields, features of clinical study, institutes, funds and keywords.Results:A total of 51 papers were included, showing an increasing trend in annual publication volume; the main research areas were pharmacology, acupuncture&moxibustion and internal medicine. Multi-center randomized controlled trials were the main clinical studies; China Academy of Chinese Medical Sciences was the leading institute in terms of publication volume; 84 funds were involved, including National Natural Science Foundation of China. Keywords that appeared most frequently were TCM, efficacy, double blind, electroacupuncture, stimulation and management.Conclusion:The number and quality of TCM research papers are improved simultaneously; future research needs to deepen international cooperation, and pay attention to the integration of TCM diagnosis and treatment characteristics and modern scientific research methods.

OBJECTIVE: To apply single cell sequencing based on multiple annealing and looping amplification cycles (MALBAC) for the determination of the rate and type of mosaicisms of high-quality embryos at cleavage stage. METHODS: After thawing and removing of zona pellucida by enzymatic digestion, blastomeres were collected the high-quality embryos donated by couples whom had given birth to healthy offspring by intracytoplasmic sperm injection and embryo transfer. The whole genome of single cell was amplified and subjected to next generation sequencing. RESULTS: From a total of 23 embryos, 184 blastomeres were collected. 175 (95.1%) of the blastomeres were successfully sequenced, of which 100 (57.1%) were found to harbor chromosomal aneuploidies. Among the 23 embryos, 3 (13.0%) were diploid, 20 (87.0%) were mosaicisms, which included 5 (21.7%) aneuploid mosaicisms, 7 (30.4%) diploid-aneuploid mosaicisms, 5 (21.7%) abnormal mosaicisms, and 3 (13.0%) irregular segregations. CONCLUSION There is a high rate of chromosomal mosaicisms in high-quality cleavage embryos. Mosaicisms of complex chromosomal abnormality or with high proportion of abnormal cells may be an important factor affecting the potential of embryonic development.
