Efficacy of Modified Wuzhuyu Decoction Granule ( ) for Migraine Patients with Cold and Stasis Obstructing Meridian Syndrome: A Randomized, Double-Blind, Placebo-Controlled Trial.

OBJECTIVE: To study the efficacy of modified Wuzhuyu Decoction Granule (, MWDG) in the treatment of migraine patients with cold and stasis obstructing meridian syndrome. METHODS: This study was a randomized, double-blind, placebo-controlled trial. A total of 78 migraine patients with cold and stasis obstructing meridian syndrome were recruited and randomly assigned by a ratio of 2:1 into a treatment group (51 cases) and a placebo group (27 cases). Patients in the treatment group were treated with MWDG while placebo granules were applied in the control group. The treatment course lasted for 12 weeks with a follow-up of 4 weeks. The primary outcome measures included frequency and days of migraine attacks and the secondary outcome measures were analgesics consumption and visual analogue scale (VAS) scores. All outcome assessments were conducted respectively at baseline, the 4th, 8th and 12th week, and the end of follow-up. RESULTS: In the treatment group, significant decrease in frequency of migraine attacks were observed since the 4th week and that of analgesics consumption since the 8th week (both P<0.05). While, in the placebo group, significant decrease in frequency of migraine attacks were observed since the 8th week and that of analgesics consumption since the 12th week (both P<0.05). No significant decrease in days of migraine attacks and VAS scores of migraine pain were observed in both groups. Between the two groups, there were significant differences in VAS scores and intensity of pain appeared in the 8th week (P<0.05). However, no significant differences were found in days and frequency of migraine attacks and analgesics consumption (P>0.05). CONCLUSIONS: MWDG was probably effective in the treatment of migraine especially for alleviating pain intensity. Furthermore, MWDG could reduce the frequency of migraine attacks and analgesics consumption sooner than the placebo.

Altered effective connectivity of resting state networks by acupuncture stimulation in stroke patients with left hemiplegia: A multivariate granger analysis.

The aim of this study was to explore the response feature of resting-state networks (RSNs) of stroke patients with left hemiplegia by acupuncture stimulation.Nineteen stroke patients with left hemiplegia and 17 controls were recruited in this study. Resting-state functional magnetic resonance imaging data before and after acupuncture were acquired using magnetic scanning. The independent component analysis (ICA) was employed to extract RSNs related to motion, sensation, cognition, and execution, including sensorimotor network (SMN), left and right frontoparietal network (LFPN and RFPN), anterior and posterior default mode network (aDMN, pDMN), visual network (VN), and salience network (SN). Granger causality method was used to explore how acupuncture stimulation affects the causality between intrinsic RSNs in stroke patients. Compared with healthy subjects, stroke patients presented the more complex effective connectivity. Before acupuncture stimulation, LFPN inputted most information from other networks while DMN outputted most information to other networks; however, the above results were reversal by acupuncture. In addition, we found aDMN reside in between SMN and LFPN after acupuncture.The finding suggested that acupuncture probably integrated the effective connectivity internetwork by modulating multiple networks and transferring information between LFPN and SMN by DMN as the relay station.

Acupuncture treatment modulates the resting-state functional connectivity of brain regions in migraine patients without aura.

OBJECTIVE: To investigate the modulatory effect of acupuncture treatment on the resting-state functional connectivity of brain regions in migraine without aura (MWoA) patients. METHODS: Twelve MWoA patients were treated with standard acupuncture treatment for 4 weeks. All MWoA patients received resting-state functional magnetic resonance imaging (fMRI) scanning before and after acupuncture treatment. Another 12 normal subjects matched in age and gender were recruited to serve as healthy controls. The changes of restingstate functional connectivity in MWoA patients before and after the acupuncture treatment and those with the healthy controls were compared. RESULTS: Before acupuncture treatment, the MWoA patients had significantly decreased functional connectivity in certain brain regions within the frontal and temporal lobe when compared with the healthy controls. After acupuncture treatment, brain regions showing decreased functional connectivity revealed significant reduction in MWoA patients compared with before acupuncture treatment. CONCLUSIONS: Acupuncture treatment could increase the functional connectivity of brain regions in the intrinsic decreased brain networks in MWoA patients. The results provided further insights into the interpretation of neural mechanisms of acupuncture treatment for migraine.

A new prognostic scale for the early prediction of ischemic stroke recovery mainly based on traditional Chinese medicine symptoms and NIHSS score: a retrospective cohort study.

BACKGROUND: Ischemic stroke (IS) is a common disease, often resulting in death or disability. Previous studies on prognosis of stroke mainly focused on the baseline condition or modern expensive tests. However, the change of clinical symptoms during acute stage is considerably neglected. In our study, we aim to develop a new prognostic scale to predict the 90-day outcome of IS patients. METHODS: In this retrospective cohort study, a secondary data analysis was performed on 489 patients extracted from 1046 patients of 4 hospitals. A new prognostic scale was constructed to predict the recovery of IS mainly based on the National Institutes of Health Stroke Scale (NIHSS) score, traditional Chinese Medicine (TCM) symptoms & signs and the changes during the first 3 days of patients in the 3 TCM hospitals. Receiver Operating Characteristic (ROC) curve was used to determine the cutoff point for prediction. In the end, the scale was used to test the outcome of IS patients in Xuanwu hospital. RESULTS: The new prognostic scale was composed of 8 items including age degree (OR = 3.32; 95 % CI: 1.72-6.42), history of diabetes mellitus (DM) (OR = 2.20; 95 % CI: 1.19-4.08), NIHSS score (OR = 3.08; 95 % CI: 2.16-4.40), anxiety (OR = 3.17; 95 % CI: 1.90-5.29) and irritability (OR = 4.61; 95 % CI: 1.36-15.63) on the 1st day of illness onset, change in NIHSS score (OR = 2.49; 95 % CI: 1.31-4.73), and circumrotating (OR = 7.80; 95 % CI: 1.98-30.64) and tinnitus (OR = 13.25; 95 % CI: 1.55-113.34) during the first 3 days of stroke onset. The total score of the scale was 16.5 and the cutoff point was 9.5, which means patients would have poor outcome at 90 days of stroke onset if the score was higher than 9.5. The new scale was validated on the data of Xuanwu hospital, and the value of its sensitivity, specificity and overall accuracy were 69.6 %, 83.3 % and 75.0 % respectively. CONCLUSIONS: The 8-item scale, mainly based on TCM symptoms, NIHSS score and their changes during the first 3 days, can predict the 90-day outcome for IS patients while it still needs to be further validated and optimized clinically.
