Traditional Chinese medicine(TCM) decoction pieces are a core carrier for the inheritance and innovation of TCM, and their quality and safety are critical to public health and the sustainable development of the industry. Conventional quality control models, while having established a well-developed system through long-term practice, still face challenges such as relatively long inspection cycles, insufficient objectivity in characterizing complex traits, and urgent needs for improving the efficiency of integrating multidimensional quality information when confronted with the dual demands of large-scale production and precision quality control. With the rapid development of artificial intelligence, machine learning can deeply analyze multidimensional data of the morphology, spectroscopy, and chemical fingerprints of decoction pieces by constructing high-dimensional feature space analysis models, significantly improving the standardization level and decision-making efficiency of quality evaluation. This article reviews the research progress in the application of machine learning in the processing, production, and rapid quality evaluation of TCM decoction pieces. It further analyzes current challenges in technological implementation and proposes potential solutions, offering theoretical and technical references to advance the digital and intelligent transformation of the industry.

Objective:To investigate the impact of programmed death receptor-1(PD-1)and its ligand(PD-L1)on the differentiation of decidual macrophages(DMs)and embryonic development.Methods:20 patients with re-current spontaneous abortion(RSA group)and 20 patients with normal pregnancy induced artificial abortion(NP group)were selected from Sichuan Provincial People's Hospital between March 2021 and January 2024.Villous and decidual tissues were obtained from both groups.Real-time fluorescent quantitative polymerase chain reac-tion(qPCR)and Western blot techniques were used to detect the expression of PD-L1 mRNA and protein in vil-lous tissues.Flow cytometry was used to analyze the types of DMs and their PD-1 expression.Human monocytic leukemia cells(THP-1)were differentiated under different conditions,with a control group and a PD-1 blocked group established,and different reagents were added into those two groups to induce differentiation,then the pro-portion of DMs types was measured in both groups.Results:PD-L1 protein and mRNA were expressed in the vil-lous tissue of both groups of patients but the expression of PD-L1 protein and mRNA was reduced in the RSA group compared to the NP group(P<0.05).The decidual tissues of both groups contained M1 and M2 macro-phages.Compared with the NP group,the ratio of M2 to M1 DMs in the RSA group was lower(P<0.05),indica-ting a polarization towards the M1 type in DMs.There was no statistically significant difference in PD-1 expression between the two groups(P>0.05).Human THP-1 cells can be stimulated to differentiate into M1 and M2 macro-phages.Afterblocking PD-1,theratioof M2 to M1 macrophages decreased(P<0.05),indicating a polarization towards the M1 type in macrophages.Conclusions:In patients with RSA,the expression of PD-L1 in villous tis-sues is decreased,and DMs polarize towards the M1 type.Blocking the PD-1/PD-L1 pathway can further promote the polarization of macrophages towards the M1 type.The influence of PD-1/PD-L1 pathway on macrophage po-larization may provide new insights into the pathogenesis of RSA.
