A true response of the brain network during electroacupuncture stimulation at scalp acupoints: An fMRI with simultaneous EAS study.

OBJECTIVES: The aim of this study was to explore simultaneous brain network responses to electroacupuncture stimulation (EAS) at scalp acupoints by accounting for placebo effects. MATERIALS AND METHODS: Sixty healthy subjects were recruited and randomly divided into two groups: Group 1 and Group 2. Functional magnetic resonance imaging (fMRI) was performed in Group 1 with sham acupuncture stimulation at acupoints Shenting (GV24) and Touwei (ST8) without EAS. Group 2 underwent verum EAS at the same acupoints during fMRI. Independent component analysis was used to analyze the fMRI data. Full-factor statistical analysis was used to compare the differences in fMRI data between the two groups and evaluate the changes in functional connectivity in brain networks after verum electrical stimulation (Group 1 [after sham electrical current stimulation - before sham electrical current stimulation] - Group 2 [after verum electrical current stimulation - before verum electrical current stimulation]) (p <.001, extent threshold k = 20 voxels). RESULTS: Six brain networks were identified. Significant increased functional connectivity was observed in the right and left executive control networks, sensorimotor network, and attention network, while decreased functional connectivity was mainly found in the default mode network. There were no statistically significant differences in the salience network. CONCLUSIONS: fMRI with simultaneous EAS provides a method to explore brain network responses due to EAS at scalp acupoints. The networks responsible for cognition are differentially activated by EAS in a coordinated manner.

Scalp acupuncture enhances local brain regions functional activities and functional connections between cerebral hemispheres in acute ischemic stroke patients.

This study aimed to explore the changes in functional connections between cerebral hemispheres and local brain regions functional activities in patients with acute ischemic stroke (AIS) treated with International Standard Scalp Acupuncture (ISSA). Thirty patients with middle cerebral artery AIS in the dominant hemisphere were selected and randomly divided into two groups such as the control group and the scalp acupuncture group, with 15 patients in each group. Patients in the control group were treated with conventional Western medicine, while patients in the scalp acupuncture group received ISSA (acupuncture at the parietal midline [MS5], acupuncture at the left anterior parietotemporal oblique line [MS6] and acupuncture at the left posterior parietotemporal oblique line [MS7]) for one course of treatment. All patients were evaluated for treatment efficacy and received whole brain resting state functional magnetic resonance imaging (Rs-fMRI) scan before and after treatment. The observational indicators included: (a) the National Institutes of Health Stroke Scale (NIHSS) scores and the simplified Fugl-Meyer Assessment (SFMA) scores; (b) analyses of the amplitude of low-frequency fluctuation (ALFF), regional homogeneity (ReHo) and voxel-mirrored homotopic connectivity (VMHC). The results showed a significant difference in the NIHSS scores before and after treatment in the scalp acupuncture group compared with the control group (p < .05), indicating that patients improved better after scalp acupuncture treatment. Compared with the control group, the VMHC, ALFF and ReHo values in the scalp acupuncture group increased after treatment. The VMHC values increased in the brain regions dominated by bilateral BA6 and BA8; the ALFF values increased in the left BA39 and the adjacent superior temporal gyrus and middle temporal gyrus; and the ReHo values increased in the brain regions extending from left middle temporal gyrus (including BA21) to BA37, and the brain regions extending from the left BA40 and angular gyrus to BA7. The present study indicated that scalp acupuncture can specifically strengthen the functional activities of the brain regions related to sensory integration, language processing and motor coordination in the middle aged and elderly patients with AIS of the dominant cerebral hemisphere, and can strengthen bilateral frontal lobe motor control. This study may provide a scientific basis for the clinical application of ISSA treatment in patients with AIS, and may also provide a preliminary research basis for further animal experiments.

Efficacy of platelet-rich plasma in androgenetic alopecia patients.

BACKGROUND: Androgenetic alopecia (AGA), a patterned hair loss in both males and females, is a commonly occurring disease worldwide. Conventionally, no curative or satisfactory treatment is available for this condition. Therefore, in the current study, we aim to use platelet-rich plasma (PRP) as an alternative treatment option for the AGA patients. MATERIALS AND METHODS: A total of 30 patients (20 men and 10 women) with AGA were included in the study between February 2017 and November 2017. Blood (9 cc) from each AGA patient was collected in 10 cc syringe, and PRP was isolated using commercially available kit under sterilized conditions. Isolated PRP was injected in the bald areas of scalp of AGA patients. The whole procedure was repeated after one month (two treatment sessions), and patients were followed for six months. The efficacy of PRP for restoration of hair was assessed using parameters such as hair density, terminal to vellus hair ratio, photographs, pull test, physician global assessment score, and patient global assessment score. RESULTS: Mean hair density on first visit (before treatment) was 34.18 ± 14.36/cm2 which was increased to 50.20 ± 15.91/cm2 after 6 months of first treatment (P value <0.05). On a scale of three, mean scores of physician and patient global assessments were 1.45 ± 0.57 and 1.60 ± 0.62, respectively. Mean percentage reduction of hair pulled was 29.2% (P value <0.05) after PRP treatment. Terminal to vellus hair ratio was increased in 60% of patients after PRP therapy. No remarkable adverse effects were noted in patients. CONCLUSION: Results showed that PRP is an effective treatment option in androgenetic alopecia as indicated by higher hair density, satisfactory physician and patient global assessment scores, and increase in terminal to vellus hair ratio.

Effects of CT-localized scalp round-needling on the blood rheology, NO and NOS of patients with multiple infarctional dementia.

OBJECTIVE: To observe the short-term therapeutic effects of CT-localized scalp round-needling on the blood rheology, nitric oxide (NO) and nitric oxide synthetase (NOS) of patients with multiple infarctional dementia. METHODS: 89 cases of multiple infarctional dementia were randomly divided into an electro-round-needling group (57 cases), and a western medication group (32 cases). The therapeutic effects, including the effects on the blood rheology, NO and NOS, were observed. RESULTS: After receiving same courses of treatment, both the electro-round-needling group and the western medication group showed significant differences in the various kinds of indexes (P < 0.05-0.01). CONCLUSION: The CT-localized scalp round-needling is an effective therapy for multiple infarctional dementia.
