Abstract:
Objective To observe the levels of neutrophil CD64 expression in prostatic fluid of patients with chronic prostatitis and different degrees of infection,to evaluate the value of CD64 in diagnosis and treatment of chronic bacterial prostatitis.Methods 100 subjects were divided into two groups according to chronic prostatitis symptom index (CPSI) established by the National Institutes of Health (NIH):CPSI high score group and CPSI low group,bacterial infection group,and 30 healthy controls.CD64 expression of neutrophils in prostatic fluid was detected by flow cytometry and prostate fluid routine microscopy inspection.Results The expression of CD64 in severe group (high score) was (4857.25±278.45) molecules / cell,which was significantly higher than that in the mild group (P＜0.05).There was significant difference between the mild group and the nonbacterial infection group or the healthy control group (P＜0.01).There was no significant difference between nonbacterial infection group and healthy control group.The expression of CD64 was positively correlated with some white blood cells in the bacterial infection group,but not the whole.ROC curve was drawn according to the data of the subjects.When CD64 was 2135.2 molecules/cell,the sensitivity was 92.9％ and the specificity was 91.7％.Conclusion Quantitative detection of CD64 in prostatic fluid can be used as a sensitive index for diagnosis of chronic bacterial prostatitis and has clinical value.
