Abstract: ObjectiveTo investigate the effect of cerebroprotein hydrolysate on diabetic peripheral neuropathy.Methods105 diabetic patients were randomly divided into the treatment group (34 cases, treated with intravenous injection of cerebroprotein hydrolysate), standard control group (38 cases, treated with intramuscular injection of Metrycobal combined with intravenous injection of Actovegin) and blank control group (33 cases, treated with oral vitamin B1, B6, B12). Curative effects of three groups were evaluated.ResultsIt was shown that intravenous injection of cerebropotein hydrolysate could improve patients' symptoms, raised speed of nerve conduction and its curative effect was as same as intramuscular injection of Metrycobal combined with intravenous injection of Actovegin.ConclusionIntravenous injection of cerebropotein hydrolysate has a curation effect on diabetic peripheral neuropathy.

Key words: diabetes, neuropathy, cerebropotein hydrolysate
