ABSTRACT
Objective The purpose of this study was to explore the expression of human fibrinogen-like protein 2 (hFgl2) in patients with cryptococcal meningitis (CM).Methods The expression of hFgl2 in the peripheral blood leukocytes from 20 CM cases and 20 healthy individuals,and the expression of hFgl2 in cerebrospinal fluid (CSF) leukocytes in 11 pairs of CM patients and matched controls was detected using immunohistochemical methods.Medical image analysis system (MIAS) was used to analyze the expression of hFgl2 gray values,which were negatively correlated to the expression of hFgl2 protein in both peripheral blood and CSF.Results The average gray values for hFgl2 protein in peripheral monocytes of CM patients and healthy controls were 114.49± 11.82 and 137.56± 10.64,respectively,and those in peripheral neutrophils were 111.71 ± 8.62 and 143.56±12.57,respectively.Compared with the healthy control group,expressions of hFgl2 in peripheral blood monocytes and neutrophils were both significantly increased in CM patients (t =21.21,t=27.19; P<0.01).The average gray values for hFgl2 protein in CSF monocytes from CM patients and negative controls were 115.44±8.67 and 149.25±8.57,respectively,and those in CSFneutrophils were 111.71±8.62 and 143.56 ± 12.57,respectively.The expressions of hFgl2 in CSFmonocytes and neutrophils were significantly increased in CM patients (t =29.95,t=28.87; P<0.01),while the expression intensity of hFgl2 was similar when peripheral blood monocytes and neutrophils compared with their CSF counterparts (t=0.924,t=0.607; both P>0.05).Conclusions hFgl2 can be expressed in both peripheral and CSF monocytes and neutrophils in CM patients.
