1·The transformability of plasmid DNA in B. subtilis competent cell depends on its molecular structure.

枯草芽孢杆菌感受态细胞的质粒转化与质粒的分子构型有关。

2·CONCLUSION: Imbalance and deficiency of immune competent cell subsets played an important role in the pathogenic mechanisms of RAU.

结论：免疫活性细胞亚群不平衡和免疫活性细胞缺陷在RAU的发病中起重要作用。
