Ischemic stroke is a common clinical disease, often accompanied by dysphagia. At present, clinical treatment for patients with dysphagia after ischemic stroke is limited. 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 mode electroacupuncture stimulation combined with NGF treatment on patients with dysphagia after ischemic stroke 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.

The 20ug mouse nerve growth factor (NO. S20060051, Jinlujie) will be obtained from Hiteck Biopharmaceutical Co., Ltd., Wuhan, China. mNGF will be dissolved in 2 ml of sterile water for injection and then injected intramuscularly into the gluteal muscle, three times a week for 6 weeks.
Patients will receive 2ml volume of physiological saline (PS) injected intramuscularly into the gluteal muscle, three times a week for 6 weeks.
Patients take supine position. After skin disinfection with 75% ethanol routine disinfection, the stainless needle (size 0.25mm×40mm, Hwato 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 Jisheng, Ltd., China) with a frequency of 2/100 Hz and an intensity of patient can tolerate, targeting a current strength of 3.0mA, for 40 min (a homemade relay cycled power to the electrode for 6 sec on and 6 sec off), three times a week for 6 weeks.

Then, the needles are connected to an acupuncture point nerve stimulator (HANS-200, Nanjing Jisheng, Ltd., China) without closed circuit, 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), three times a week for 6 weeks.
