“…All participants were asked to lie still in a Siemens TRIO 3 Tesla machine using the same scanning parameters as follows: 64 × 64 acquisition matrix; flip angle = 80°; echo time (TE) / repetition time (TR) = 30/3000 ms; pixel spacing Y/pixel spacing X = 3.3/3.3mm; 140 image volumes; 48 axial slices; 3.313 mm slice thickness with no gap. During the scan, all participants should close eyes but keep awake with thinking of nothings ( Liu et al, 2018 ).…”

Alzheimer’s disease (AD) could be described into following four stages: healthy control (HC), early mild cognitive impairment (EMCI), late MCI (LMCI) and AD dementia. The discriminations between different stages of AD are considerably important issues for future pre-dementia treatment. However, it is still challenging to identify LMCI from EMCI because of the subtle changes in imaging which are not noticeable. In addition, there were relatively few studies to make inferences about the brain dynamic changes in the cognitive progression from EMCI to LMCI to AD. Inspired by the above problems, we proposed an advanced approach of evolutionary weighted random support vector machine cluster (EWRSVMC). Where the predictions of numerous weighted SVM classifiers are aggregated for improving the generalization performance. We validated our method in multiple binary classifications using Alzheimer’s Disease Neuroimaging Initiative dataset. As a result, the encouraging accuracy of 90% for EMCI/LMCI and 88.89% for LMCI/AD were achieved respectively, demonstrating the excellent discriminating ability. Furthermore, disease-related brain regions underlying the AD progression could be found out on the basis of the amount of discriminative information. The findings of this study provide considerable insight into the neurophysiological mechanisms in AD development.

“…Zhou et al [16] found that acupuncture at the points of the Lung Meridian could significantly strengthen ALFF in the right gyrus subcallosum and inferior frontal gyrus and weaken in the right postcentral gyrus, left precuneus, superior temporal gyrus, and middle temporal gyrus and needling at the Lung Meridian points could alter inherent activities of the cerebral cortex. Liu et al [17] observed that compared with before acupuncture, the ReHo in cognitive network, motor network, default network, and limbic system encephalic changed after acupuncture at GB34.…”

Research exploring the mechanism of acupuncture has been a hot topic in medicine. Resting-state functional magnetic resonance imaging (rs-fMRI) research is a noninvasive and extensive method, which is aimed at the research of the mechanism of acupuncture. Researchers use fMRI technologies to inspect the acupuncture process. The authors reviewed the application of rs-fMRI in acupuncture research in recent 10 years from the aspects of studying acupoints, subjects, acupuncture methods, and intensities. The results found that the application of rs-fMRI in acupuncture research mainly includes research on the onset mechanism of acupuncture treatment; visual evidence of diagnosis and treatment of dominant diseases; efficacy assessments; physiological mechanism of acupoint stimulation; and specific visualization of acupoints.

“…They found that the values of ReHo increased in the anterior cingulated gyrus, left temporal gyrus, right inferior parietal lobule, and right frontal gyrus, whereas it decreased in the left thalamus, right insular cortex, left inferior frontal gyrus, and right anterior cingulate, which was induced by acupuncture on the GB34 point (preacupuncture versus. postacupuncture) (L. Liu et al., 2018). Currently, more rsfMRI studies set up a sham acupuncture session during the experimental design, which is believed to obtain reliable results of acupuncture effects (Asakawa & Xia, 2013; Chen et al., 2020).…”

“…On the basis of this knowledge, we designed an explorative rsfMRI study, being analogous to a previous study (L. Liu et al., 2018), to explore the cerebral areas associated with changes in ReHo and ALFF values induced by unilateral acupuncture on the SP3 point in healthy subjects. For obtaining a convincing result, we also used a sham acupuncture session according to a previous study (Qiu et al., 2012).…”

Objective The study aimed to explore the cerebral areas with changes in regional homogeneity (ReHo) and amplitude of low‐frequency fluctuation (ALFF) values induced by effective acupuncture on the Taibai (SP3) point. Methods In the study, 15 healthy right‐handed volunteers (seven males and eight females, 20–35 years old) were enrolled. The average ages of the subjects were 28.0 ± 4.24 years for males and 27.4 ± 3.65 years for females. A 3.0T magnetic resonance imaging (MRI) system was used to perform resting‐state functional MRI scan after sham and effective acupuncture on the SP3 point. The differences in cerebral ReHo and ALFF values between posteffective acupuncture and postsham acupuncture were compared using the SPM 12 software. Results ReHo values of bilateral BA18, cuneus, and BA17, along with BA41, BA22, postcentral gyrus, and BA7 on the right side, were decreased by effective SP3 acupuncture. The ALFF values of bilateral BA 30 and left parahippocampal area were increased, whereas the values of bilateral BA18, BA19, cuneus, posterior cingulate gyrus, and BA7, along with the right superior occipital lobule, postcentral gyrus, and left precuneus, were decreased. Conclusions The most dominant cerebral areas affected by SP3 acupuncture were bilateral visual‐related cortices (lingual gyrus, cuneus, and calcarine), along with the unilateral postcentral gyrus and superior parietal lobule. These findings may be potential explanations for the available clinical reports concerning the efficacy of SP3 acupuncture. Further clinical and experimental studies on SP3 acupuncture are required.
