Objective: To study the levels of beta-endorphine (β-EP) in serum and cerebrospinal fluid and the changes in erythrocyte immunological function in children with nervous system infectious diseases.

Methods: Fifty-six children with nervous system infectious diseases (Observation group) and forty-four aged-matched children with no nervous diseases (Control group) were selected. The levels of beta-endorphine in serum and cerebrospinal fluid, the quantity of complement receptor type I expressed on erythrocytes (ECR1) and the rate of red cells native adhesion to tumor cells (NTRR) were determined.

Results: The levels of β-EP in serum and cerebrospinal fluid in observation group was obviously higher than that in control group. Compared with control group, the quantity of ECR1 had no obvious changes and NTRR obviously fell in observation group. The levels of β-EP in cerebrospinal fluid in severe symptom group was obviously higher than that in light symptom group of observation group, and NTRR in severe symptom group was obviously lower than that in light symptom group . What is more, the more severe the disease condition was , the higher the levels of β-EP in serum and cerebrospinal fluid were, and the lower NTRR was.

Conclusion: Beta-endorphine has dual regulation of erythrocyte immunological function, and both of them relate to the disease condition.
