CTSS and alkaline phosphatase measurement: Although we did not conduct studies on the activities of cathepsins, this analysis on the upstream activity of autophagy by introducing CQ to block the lysosome‐driven degradation could be used at least to support that autophagy was activated during AP and the extent was positively correlated with the incubated level of H2S. The ratio of LC3II to LC3I, also named as LC3 conversion, indicates the net effects of formation and clearance of autophagosomes.
