[Therapeutic effect of nape cluster acupuncture combined with swallowing function training on post-stroke dysphagia].

OBJECTIVE: To observe the effect on swallowing function in patients with post-stroke dysphagia treated with nape cluster acupuncture and the immediate effect of acupuncture at Fengchi (GB 20). METHODS: A total of 60 patients with post-stroke dysphagia were randomized into an observation group and a control group, 30 cases in each one.On the basis of conventional western medication treatment, swallowing function training was applied in the control group, once a day.On the base of the treatment as the control group, nape cluster acupuncture was applied at Fengchi (GB 20), Tianzhu (BL 10), Wangu (GB 12), Lianquan (CV 23), Panglianquan (Extra), Jinjin (EX-HN 12) and Yuye (EX-HN 13) in the observation group, once a day. Additionally, pricking blood was applied at Jinjin (EX-HN 12) and Yuye (EX-HN 13), 2 times a week. The treatment was given 30 min each time, a week as one course and 4 courses were required. Before and after treatment, the standardized swallowing assessment (SSA) score and video fluoroscopic swallowing study (VFSS) score were compared in the two groups. The ultrasonic diagnostic device of swallowing and surface electromyography were used to observe the immediate effect on swallowing related muscles of acupuncture at Fengchi (GB 20). RESULTS: Compared before treatment, the SSA scores were reduced after treatment in the two groups (P<0.05), and the change of the observation group was larger than the control group (P<0.05). Compared before treatment, the VFSS scores were increased after treatment in the two groups (P<0.05), and the change of the observation group was larger than the control group (P<0.05). Acupuncture at Fengchi (GB 20) immediately increased the amplitude of submental muscles and infrahyoid muscles in the observation group (P<0.05), the geniohyoid muscle movement time was reduced and geniohyoid muscle displacement was increased (P<0.05). CONCLUSION: On the base of the routine treatment, nape cluster acupuncture could improve swallowing function in patients with post-stroke dysphagia. Acupuncture at Fengchi (GB 20) could immediately affect swallowing related muscles, improve muscle amplitude and reduce swallowing time.

Effect and Safety of Hydroxysafflor Yellow A for Injection in Patients with Acute Ischemic Stroke of Blood Stasis Syndrome: A Phase II, Multicenter, Randomized, Double-Blind, Multiple-Dose, Active-Controlled Clinical Trial.

OBJECTIVE: To assess the effect and safety of Hydroxysafflor Yellow A for Injection (HSYAI) in treating patients with acute ischemic stroke (AIS) and blood stasis syndrome (BSS). METHODS: A multicenter, randomized, double-blind, multiple-dose, active-controlled phase II trial was conducted at 9 centers in China from July 2013 to September 2015. Patients with moderate or severe AIS and BSS were randomly assigned to low-, medium-, high-dose HSYAI groups (25, 50 and 70 mg/d HSYAI by intravenous infusion, respectively), and a control group (Dengzhan Xixin Injection (, DZXXI) 30 mL/d by intravenous infusion), for 14 consecutive days. The primary outcome was the Modified Rankin Scale (mRS) score ⩽1 at days 90 after treatment. The secondary outcomes included the National Institute of Health Stroke Scale (NIHSS) score ⩽1, Barthel Index (BI) score ⩾95, and BSS score reduced ⩾30% from baseline at days 14, 30, 60, and 90 after treatment. The safety outcomes included any adverse events during 90 days after treatment. RESULTS: Of the 266 patients included in the effectiveness analysis, 66, 67, 65 and 68 cases were in the low-, medium-, and high-dose HSYAI and control groups, respectively. The proportions of patients in the medium- and high-dose HSYAI groups with mRS score ⩽1 at days 90 after treatment were significantly larger than the control group (P<0.05). The incidences of favorable outcomes of NIHSS and BI at days 90 after treatment as well as satisfactory improvement of BSS at days 30 and 60 after treatment in the medium- and high-dose HSYAI groups were all significantly higher than the control group (P<0.05). No significant difference was reported among the 4 groups in any specific adverse events (P>0.05). CONCLUSIONS: HSYAI was safe and well-tolerated at all doses for treating AIS patients with BSS. The medium (50 mg/d) or high dose (75 mg/d) might be the optimal dose for a phase III trial. (Registration No. ChiCTR-2000029608).

[Effects of eye acupuncture on SEPCT-determined cerebral blood flow in patients with cerebral infarction].

UNLABELLED: OBJECTIVE To verify the correlation between the points of eye acupuncture and zang-fu function so as to provide the theoretical evidence for the principle of point selection in eye acupuncture therapy. METHODS: Sixty cases of cerebral infarction were treated with different points according to syndrome differentiation of Chinese medicine. MAIN POINTS: upper energizer area and lower energizer area. Supplementary points: liver area, kidney area and spleen area for hyperactivity of wind, phlegm and fire; liver area and spleen area for blockage of wind, phlegm and stasis; stomach area and large intestine area for excess fu syndrome due to phlegm heat; heart area and spleen area for qi deficiency and blood stasis; liver area and kidney area for yin deficiency and wind stirring. The single photon emission computed tomography (SPECT) was adopted to observe the changes in blood flow in local foci before and after treatment with eye acupuncture. RESULTS: After the treatment with eye acupuncture therapy, the intake ratio of region of interest (ROI) between the lesion area and corresponding area on the opposite side was 0.74 +/- 0.12 before eye acupuncture and was 0.91 +/- 0.08 after treatment, indicating significant statistical difference in comparison (P < 0.05). After eye acupuncture, cerebral blood flow increased apparently. CONCLUSION: The point selection according to syndrome differentiation in eye acupuncture therapy may increase local brain blood flow in the patients with cerebral infarction and improve the state of brain ischemia so that the correlation can be proved between the points of eye acupuncture and zang-fu function.
