In order to better match the teaching hours of clinical anesthesiology with the teaching content of modem anesthesia, the teachers must take full advantage of various supplementary teaching methods in the limited teaching hours to help enhance the students' enthusiasm in active learning, help the students concentrate on the crucial points and apply their knowledge and ultimately improve the teaching quality.

Objective To study the changes of AKP activity and its cytochemistry position during liver regeneration following partial hepatectomy. Methods Using colorimetry to analyze AKP activity; using non-denatured electrophoresis technique to analyze the kinds and activity of AKP; using electron microscope cytochemistry to analyze its position. Results During liver regeneration, AKP activity had two peaks at 16*!h and 19*!h and followed by decline dramatically; Three hepatic-derived AKP isoenzymes were detected, and 180*!kD AKP appeared only in liver regeneration; AKP appeared in different part with the process of liver regeneraion.Conclusion AKP plays an important role in liver regeneration and it may involve in cell metabolism, material transportation, DNA synthesis and cell differentation.
