Vietnam,as an important country along the "one belt and one road",is closely related to China.Chinese traditional medicine has entered Vietnam and gained strong support from policy and public recognition.It has a good foundation for development and a bright future.Based on the current situation of traditional Chinese medicine exchanges between China and Vietnam and Vietnam's basic national conditions,the author puts forward that exploring new cooperative models through multi-level cooperative projects,which relys on the role of the Chinese Chamber of Commerce,and adheres to the complementary promotion between trade in services and trade in goods.They are the feasible ways for Chinese medicine to develop in Vietnam.The development of Chinese medicine in Vietnam needs the adherance to the four principles of bidirectional positioning,suiting measures to local conditions,standardizing standards and risk prevention.

Objective To investigate whether human RhoA is modified by SUMO. Methods Overlap extension PCR and double digestion technique were used to construct the eukaryotic expression vector pcDNA3-3flag-RhoA, which was identified by sequencing. The plasmid was transfected into HEK293T cells and its expression was detected by Western blotting. Immunofluorescence assay was used to detect whether RhoA is co-localized with SUMO. Co-Immunoprecipitation was used to detect whether RhoA is modified by SUMO. Results The recombinant plasmid pcDNA3-3flag-RhoA was successfully constructed and verified. Western blotting showed that the recombinant plasmid pcDNA3-3flag-RhoA expressed abundant fusion protein in HEK293T cells. Immunofluorescence showed that RhoA was co-localized with SUMO2/3 but not with SUMO1. Co-immunoprecipitation verified that RhoA was modified by SUMO2/3 but not SUMO1. Conclusion Human RhoA is modified by SUMO2/3 and probably participates in the regulation of axon regrowth after nervous system injury.
