Lipocalin 2(LCN2)plays a pivotal role in iron metabolism,particularly in the context of microbial infection resistance(e.g.,viruses,bacteria,parasites,etc.).LCN2 combats microbial infection by directly assisting the body in competing with microorganisms for iron,inducing immune cells to secrete various cytokines to enhance systemic immune responses,or recruiting neutrophils to infectious *** liver serves as the primary organ for LCN2 secretion during microbial *** review encapsulates recent advances in dynamic changes,clinical values,and the effects of LCN2 in infectious liver diseases caused by various microbial microorganisms.

With the progression of CKD1-5, the proportion of Yin deficiency and dry heat syndrome,and that of Qi and Yin deficiency syndrome showed a downward trend, whereas the proportion of spleen-kidney Yang deficiency, blood deficiency, blood stasis, water stagnation, and phlegm turbidity syndromes showed an upward trend; the differences were statistically significant(P liver-kidney Yin deficiency syndrome was positively correlated with age(OR = 1.028, P = 0.021) and glycosylated hemoglobin(OR = 1.223, P = 0.007) but negatively correlated with total cholesterol(OR = 0.792, P = 0.006).Spleen-kidney Yang deficiency syndrome was negatively correlated with hemoglobin(OR = 0.977, P < 0.001),albumin(OR = 0.891, P < 0.001), and eGFR(OR = 0.978,P < 0.001) but positively correlated with high density lipoprotein(OR = 3.376, P = 0.001). CONCLUSION: With CKD1-5 progression, TCM syndromes changed from Yin deficiency and dry

Nonalcoholic fatty liver disease(NAFLD)is one of the most common chronic liver diseases,yet it has not received sufficient attention[1].Over the past two decades,the overall global prevalence of NAFLD has risen from 25%to 37%[2].The disease burden of NAFLD is fueled by the epidemic of obesity and diabetes[3].It is estimated that more than half of patients with diabetes have NAFLD.
