  1. The results are average ± standard deviation (n = 3). Different superscript letters in a column indicate statistical significant difference (p < 0.05) in the least significant difference test. S1, no obvious deterioration; S2, mild deterioration; S3, moderate deterioration; S4, severe deterioration
