Guizhi-Fuling Pill combined with conventional western medicine therapy for diabetic peripheral neuropathy / 国际中医中药杂志

ABSTRACT

Objective To evaluate the therapeutic effect ofGuizhi-Fuling Pill combined with conventional western medicine therapy for diabetic peripheral neuropathy (DPN).Methods A total of 78 patients with DNP were randomly divided into treatment group (40 patients) and control group (38 patients).The patients in the control group were administrated with mecobalamin on the basis of conventional treatment. In addition to the therapy of control group,patients in treatment group were givenGuizhi-Fuling Pill. The patients in both groups were treated for 2 weeks.The level of homocysteine (Hcy) and sensory nerve conduction velocity (SNCV) and motor nerve conduction velocity (MNCV) in both groups were measured. Toronto clinical scoring system (TCSS) was used to evaluate the curative effect.Results The total effect rate in the treatment group was significantly higher than that in the control group (95.0%vs. 76.3%;χ2=5.616,P=0.018). After treatment, the MNCV of common peroneal nerve (46.1 ± 6.3 m/svs.42.5 ± 5.5 m/s;t=2.734,P<0.01 ), MNCV of median nerve (49.8 ± 5.2 m/svs.46.3 ± 5.9 m/s;t=2.607,P<0.05 ), SNCV of common peroneal nerve (38.5 ± 4.6 m/s vs. 35.4 ± 4.3 m/s;t=3.105,P<0.05 ), SNCV of median nerve (45.3 ± 5.2 m/svs. 42.3 ± 4.8 m/s;t=2.627, P<0.05 ) in the treatment group were significantly increased than those in the control group. The integral of TCSS (5.3 ± 3.1vs. 7.2 ± 2.9;t=2.823,P<0.01) and the level of Hcy (13.3 ± 3.2 μmol/Lvs. 17.1 ± 3.4 μmol/L;t=5.178, P<0.05) were significantly lower in treatment group than those in control group (P<0.05).Conclusions The Guizhi-Fuling Pill combined with conventional western medicine therapy could improve MNCV and SNCV and reduce the level of Hcy and improve the clinical effect.
