The difference in the levels of GLU,TCH, and HDL-C among the groups was significant(P<0.05), classified in terms of slippery, moist, and dry fur. Further comparison between the groups by Student-Newman-Keuls test showed that GLU level in the dry fur group was the highest. Moreover, the TCH level in the slippery fur group was higher than the other two groups.CONCLUSION: A correlation between tongue manifestations and GLU, TCH, HDL-C was identified in the patients with acute cerebral infarction.展开更多
