The Impact of Electroacupuncture Combined With NGF on Clinical Effect and Functional Changes on Ischemic Stroke

Summary

Ischemic stroke is a common clinical disease, often accompanied by motor dysfunction and cognitive impairment. At present, clinical treatment for patients with ischemic stroke recovery is limited and ineffective. The emergence of NGF has surprised the field of neurorehabilitation, but the clinical effect is not satisfactory. The main problem is that NGF is a macromolecular material with a molecular weight of 13.4 KD, which is difficult to penetrate the blood brain barrier. A large number of previous studies in our team have found that electroacupuncture with specific stimulation mode can open the blood brain barrier and induce NGF into the brain。Therefore, the purpose of this study is to investigate the effect of specific stimulation mode electroacupuncture combined with NGF treatment together with rehabilitation training on patients with ischemic stroke recovery period and to explore the mechanism of this combination therapy to improve brain function, which creates a new method and theoretical basis for nerve rehabilitation of integrated traditional Chinese and Western medicine.

Conditions

• Ischemic Stroke

Interventions

DRUG

Nerver growth factor (NGF) injection

The 20ug nerve growth factor (NO.S20060051, Jinlujie) will be obtained from Hiteck Biopharmaceutical Co., Ltd, Wuhan, China. mNGF will be dissolved in 1 ml sterile water for injection and then injected intramuscularly at gluteal muscle, once a day for 4 weeks. Dose modification is not allowed for mNGF.

DRUG

Placebo injection

The patients will receive 1ml volume of physiological saline (PS) injected into the gluteal muscle, once a day for 4 weeks.

DEVICE

EA intervention

Patients take supine position. After skin disinfection with 75% ethanol routine disinfection, the stainless needle (size 0.25mm×40mm, Hua Tuo brand, Suzhou Medical Supplies Company Ltd in Jiangsu, China) will be inserted in GV20（Baihui) and the stainless needle(size 0.25mm×25mm, described above) will be inserted in GV26 (Shuigou), acupoints will be stimulated manually until patients feel soreness, distension or heaviness (the reaction of "De Qi"). Then, the needles are stimulated by using an acupuncture point nerve stimulator (HANS-200, Nanjing Jinsheng, Ltd., China) with a frequency of 2/100 Hz and an intensity of 3 mA for 40 min (a homemade relay cycled power to the electrode for 6 sec on and 6 sec off), 28 days as a course of treatment, once a day.

DEVICE

sham EA intervention

The only difference between sham EA intervention and EA intervention is that the stimulator is connected to the needle handle without power for 40 min intervention.
