Objective To investigate the influence of recombinant human bone morphogenetic protein‐2(rhBMP‐2)of poly lactic acid(PLA) release microspheres for compatibility of rabbit bone marrow mesenchymal stem cells(BMSCs) .Methods The rh‐BMP‐2‐PLA release microspheres were prepared by w/o/w multiple emulsion volatilizing method and then cocultured BMSCs .The effects of rhBM P‐2‐PLA release microspheres on the cytotoxicity and relative proliferation rate by MTTassay .Evaluation of mate‐rials biocompatibility by inverted microscope and scanning electron microscope(SEM) .Results The rhBMP‐2‐PLA release micro‐spheres in various concentration of leaching solution and BMSCs training of uninfected cells .Experimental group and control group in 4 different time cell proliferation OD values by analysis of repeated measurement variance between time OD values were statisti‐cally significant(P=0 .000) ,the experimental group and control group OD values are statistically significant(P=0 .025) ,the exper‐imental group higher than the control group ,experimental group OD value time there was a significant interaction effect and the group number ,the change trend are obviously different(P=0 .006) .Inverted microscope to observe materials normal cell prolifera‐tion ,SEM found that vaccination cells surrounding rhBMP‐2‐PLA release microspheres of 7 days later ,the cells grew well and split proliferation activity .Conclusion rhBMP‐2‐PLA release microspheres of BMSCs has non‐toxic and has compatibility .

Due to the complexity of traditional Chinese medicine （TCM） interventions and the diversity of herbal components， single-omics technologies such as genomics， transcriptomics， proteomics， and metabolomics often cannot comprehensively elucidate the scientific connotations of TCM. Multi-omics technologies driven by system biology can analyze the theoretical connotations and application mechanisms of TCM from different levels such as genes， gene expression， proteins， and metabolites， in line with the holistic view of TCM， which helps to promote the modernization of TCM. By reviewing the literature on the application of omics technologies in the field of TCM， it is found that multi-omics technologies have been widely used in TCM for syndrome differentiation， evaluation of herbal quality， elucidation of pharmacological mechanisms， and drug toxicity assessment， providing comprehensive explanations of the mechanisms of action of TCM and overcoming the limitations of single-omics technologies， and having obtained significant achievements. However， multi-omics technologies also face challenges such as high cost， difficulties in data analysis due to large data volumes， and insufficient translation of research results. In the future， it is expected that through strengthening interdisciplinary cooperation， conducting long-term and dynamic clinical research， standardizing and normalizing data analysis processes， adopting appropriate and reasonable multi-omics integration patterns， establishing multi-omics databases for TCM， revealing the individualized characteristics， therapeutic mechanisms， and disease regulatory networks of TCM， the modernization of TCM will be promoted.
