Objective To learn surgical nurses about their critical thinking ability and learning ability in order for nursing administrators to provide theoretical basis for improvement of critical thinking and self-learning ability of surgical nurses. Methods We investigated 200 nurses of three hospitals in surgery by California Critical Thinking Disposition Inventory(CCTDI) and Scale of Self-directed Learning Competence. Results Surgical nurse' critical thinking score was (282.41±19.87), and has a positive critical thinking; self-learning ability score was (131.65±10.29), the overall scores was at higher levels. Conclusions Care managers should pay attention to the surgical nurse' critical thinking skills and independent learning abilities and improve their quality of nursing staff.

Indanomycins are a class of secondary metabolites of microorganisms with a trans-tetrahydroindan (indane) ring. These compounds generally have good antibacterial, insecticidal and antitumor biological activities, which have caused wide interest for medicinal chemists and biologists. This review summarizes the research progress of the discovery, biological activity, chemical synthesis and biosynthesis of indanomycin compounds since 1979 and provides scientific reference for the research and development of indanomycin antibiotics.
