Methods and compositions for treating pain in mammalian subjects are provided. The methods include obtaining blood or a fraction of blood from the subject, measuring a therapeutic indicator in the blood or in the fraction blood, and administering an anti-inflammatory composition to the subject if the therapeutic indicator is equal to or above a threshold level. The anti-inflammatory composition comprises a protein solution including interleukin-1 receptor antagonist. The protein solution may be prepared from the blood or blood fraction obtained from the subject.

The invention discloses an expression system of fusion protein from human serum albumin and interleukin-1 receptor antagonist. The expression system comprises a host cell and an expression vector transferred into the same. The expression vector comprises a first expression vector with an inserted fusion protein gene and a second expression vector with an inserted protein disulfide isomerase gene.The fusion protein gene comprises the human serum albumin and the interleukin-1 receptor antagonist. The host cell is Pichia pastoris GS115. The co-expression host of PDI (protein disulfide isomerase) and IGH (immunoglobulin heavy) is established, and expression index of the IGH is evidently increased. The PDI is expressed intracellularly, the IGH secretory expression is subjected to extracellular secretory expression, and accordingly no newly generated other proteins occur when concentration of the IGH in collected medium supernate increases.
