Clinical efficacy and safety of electro-acupuncture combined with beraprost sodium and α-lipoic acid for diabetic peripheral neuropathy.

The pathogenic triggers of diabetic peripheral neuropathy (DPN) mainly include ischemia and hypoxic factors. The combined use of Chinese and Western medicine may be a new perspective for the treatment of DPN. Accordingly, this study explores the clinical efficacy and safety of electro-acupuncture (EA) combined with beraprost sodium (BPS) and α-lipoic acid (α-LA) in the treatment of patients with DPN.A total of 184 patients with DPN meeting the inclusion criteria were enrolled and divided into electric-acupuncture group (n=54), medication group (n=62) and combination group (n=68), which were treated by EA, BPS+α-LA, and EA+BPS+α-LA, respectively. The three groups were compared with respect to the following factors: clinical efficacy; motor conduction velocities (MCVs) of nervus medianus, nervus peroneus communis and tibial nerve and sensory conduction velocities (SCVs) of nervus medianus, sural nerve and ulnar nerve before and after treatment; the Toronto Clinical Scoring System (TCSS), total symptom score (TSS) and Michigan Diabetes Neuropathy Score (MDNS) before and after treatment; changes of serum homocysteine and cysteine (Cys) levels, oxidative stress indicators and inflammatory factors; incidence of adverse reactions.The overall response rate of the combination group was higher than that of the electric acupuncture group or the medication group. After treatment, the SCV of nervus medianus, sural nerve and ulnar nerve and the MCV of nervus medianus, nervus peroneus communis and tibial nerve were the highest in the combination group among the three groups (P<0.05). After treatment, the scores of TCSS, TSS and MDNS in the combination group was notably lower than those in the medication group and the electric acupuncture group (P<0.05). The amelioration of inflammatory factors in the combination group were the best among the three groups (P<0.05). The incidence of adverse reactions was lower in the combination group compared with the electric acupuncture group and the medication group (P<0.05).EA combined with BPS and α-LA is effective in the treatment of DPN, which can effectively reduce the levels of serum inflammatory factors in patients, with a lower complication rate and higher safety.
