BACKGROUND:Chitosan (CS) holding a good biocompatibility, biodegradability, antibacterial property and hemostasis effect cannot only promote wound healing and tissue repair, but also exhibit sustained-control release when carrying berberine hydrochloride (Bh). Therefore it functions as an excellent antibacterial and hemostatic material. OBJECTIVE:To prepare the porous CS/Bh composite xerogel and observe its antibacterial and hemostatic properties. METHODS:The porous CS/Bh composite xerogel was prepared using freeze-drying method, and its microstructure was characterized by scanning electron microscope and Fourier transform infrared spectrometer. The biocompatibility was detected through MTT assay and the in vitro antibacterial and hemostatic properties were observed through antibacterial test and blood clotting index. RESULTS AND COCNLUSION:The porosity of the CS/Bh composite xerogel was 83.1%-90.5%and almost degraded after 72 hours of immersion in PBS. The in vitro antibacterial and hemostatic properties of the composite xerogel were significantly better than those of CS, which were enhanced with the Bh content increasing. Additionally, the CS/Bh (10%) composite xerogel showed the best hemostatic and antibacterial abilities in vitro. To conclude, the CS/Bh composite xerogel possesses a good biocompatibility and strong hemostatic and antibacterial abilities, which is a promising postoperative antibacterial and hemostatic material.

BACKGROUND: Human leukocyte antigen-E (HLA-E) is one of non-classical HLA class I genes. Up to now, the polymorphism analysis is mainly aimed at the variation in exon 3 of HLA-E, which determines HLA-E*01:01 or HLA-E*01:03. However, the identification of the full-length HLA-E and its novel alleles is rare reported.OBJECTIVE: To establish the method of identification of HLA-E genomic full-length sequence, and to identify its novel alleles in healthy blood donors in Shenzhen, China.METHODS: Peripheral blood DNA samples were extracted from the subjects, and the amplified primers and sequencing primers in conserved regions were designed according to the sequences of HLA-E published in the IMGT/HLA database.A high-fidelity reaction system was used to amplify the genomic full-length of HLA-E, followed by sequencing,assembling, confirming and typing.RESULTS AND CONCLUSION: Herein, we successfully established the method for amplifying genomic full-length sequence and sequence-based typing. Two novel HLA-E alleles were nominated by WHO HLA Nomenclature committee as HLA-E*01:01:01:06 and HLA-E*01:01:01:07. Compared with the most related allele HLA-E*01:01:01:01,HLA-E*01:01:01:06 had one nucleotide change at nt-26(G->T) in 5'-promoter, and HLA-E*01:01:01:07 had one nucleotide change at nt3345(T->C) in 3'-UTR. The polymorphism data of genomic full-length HLA-E in Chinese individuals need to be filled, and the method we developed here supplies the key technique for the further studies.
