Objective To compare the immediate effects of acupuncture at the true and false acupoints of Yanglingquan on functional connectivity in sensorimotor network(SMN)and dorsal attentional network(DAN)of stroke patients based on functional magnetic resonance imaging(fMRI)technology;To explore the central regulatory mechanism and acupoint specificity of acupuncture in stroke patients with hemiplegia.Methods Totally 20 patients with stroke and hemiplegia were included in the study.fMRI scans of acupuncture at the true and false acupoints of Yanglingquan were performed once every 2 weeks,and motion-related SMN and DAN were extracted by independent component analysis to compare the differences in functional connectivity.Results In SMN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior temporal gyrus,inferior frontal gyrus,cuneiform lobe,and anterior cuneiform lobe,as well as the left middle temporal gyrus,occipital gyrus,superior temporal gyrus,parahippocampal gyrus,inferior frontal gyrus,and superior temporal gyrus.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior central gyrus,superior frontal gyrus,middle frontal gyrus,and cingulate gyrus,as well as the left medial frontal gyrus,anterior cingulate gyrus,lentiform nucleus,and caudate nucleus.In DAN,after acupuncture at the Yanglingquan true acupoint,the functional connectivity was enhanced compared with before acupuncture.The enhanced brain areas included the right anterior cingulate lobe,superior temporal gyrus,middle temporal gyrus,and occipital gyrus,as well as the left cingulate gyrus,posterior cingulate gyrus,and anterior cingulate lobe.After acupuncture at the Yanglingquan false acupoint,the functional connectivity was enhanced compared with before acupuncture,and the enhanced brain areas included the right anterior cingulate gyrus,left anterior cingulate gyrus,and medial frontal gyrus.Conclusion Acupuncture at Yanglingquan can activate SMN and DAN bilateral related brain regions in patients with hemiplegia,which may promote the recovery of motor function by regulating the initiation and execution of motor activities,and has more acupoint specificity compared with false acupoint.

Yi He Rehabilitation,which is based on traditional Chinese rehabilitation treatments and rehabilitation principles from modern medicine,is effective in staging treatment of post-stroke hemiplegia.This paper systematically discusses the origin and annotation of Yi and He from the perspectives of traditional Chinese medicine and modern medicine.The medicinal connection between Yi and the body and its function is related to unobstructed attunement.Based on the connotation of Yi and He,we believe that the pathogenesis of post-stroke hemiplegia is the comprehensive result of abnormal effects of Yi on the organism at the microscopic level and abnormal effects of He on function at the macroscopic level,featured as tense muscle movement and a pathological process of abnormal motion,including the disturbance of yang qi with body dysfunction,the disorder of spirit with sinews and vessels with diversion,and the variation of brain collateral with physical and mental inconsistency.By inducing relaxation and calmness,Yi He rehabilitation takes effect in staging treatment of post-stroke hemiplegia with characteristic mechanisms.First,by calming ascending yang and relaxing the disordered body in periods of relaxation,it can achieve the maintenance function of the kinematic chain peripherally with passive rehabilitation.Second,by calming the disordered spirit and relaxing the inhibited meridian sinews in spasmodic periods,it can reconstruct the neural plasticity of motor function centrally with assistive rehabilitation.Third,by calming damaged brain collateral and relaxing the impassable zang organs in the recovery period,it can close the central-peripheral-central loop of rehabilitation with active rehabilitation.

Objective To compare the changes of brain voxel-mirrored homotopic connectivity(VMHC)of patients before and after Tai Chi Chuan training based on functional magnetic resonance imaging(fMRI)technology;To discuss the central effect mechanism of Tai Chi Chuan in treating chronic fatigue syndrome(CFS).Methods A total of 25 CFS patients(experiment group)and 27 healthy individuals(control group)were recruited to undergo a 1-month Tai Chi Chuan intervention.All receive one month of Tai Chi Chuan training.Differences in SF-36 scores and VMHC between CFS patients and HCs were compared.Results Before training,the SF-36 scores in the experimental group were significantly lower than those in the control group(P<0.001),and the VMHC in the bilateral inferior occipital gyrus,paracentral lobule,lingual gyrus,insula and superior temporal gyrus brain areas were weakened.After training,the scores of SF-36 in the experimental group significantly increased(P<0.001),and the VMHC in bilateral inferior occipital gyrus,superior temporal gyrus,anterior cuneiform lobe and paracentral lobule were significantly enhanced.The difference in whole brain VMHC was positively correlated with the difference in energy scores in SF-36(r=0.456,P=0.025);some scores of SF-36 in the control group significantly increased(P<0.05),and no significant changes in VMHC were observed in brain regions.Conclusion Tai Chi Chuan can effectively improve the quality of life of patients with CFS.This change may be related to the enhancement of functional connections in brain regions such as inferior occipital gyrus,superior temporal gyrus,precuneus,paracentral lobule,et al.

Objective:To explore the changes of sensorimotor network functional connectivity and coefficient of variation of dyanmic functional connection in stroke patients before and after acupuncture on the left Yanglingquan by means of functional magnetic resonance, and explore the effect mechanism of needle retention.Methods:Twenty five patients with right subcortical cerebral infarction who were hospitalized in Dongzhimen Hospital from September 2014 to September 2019 were selected as the experimental group.In the same period 21 healthy controls were selected as healthy control group. The resting state and acupuncture state images were collected by functional magnetic resonance imaging, and the images were preprocessed. The sensory motor brain network of subjects was extracted by independent component analysis (ICA). The functional connectivity and dynamic changes were compared before and after acupuncture based on the sensory motor network.Results:In the experimental group, there were differences between acupuncture state and resting state in the left inferior parietal lobule. The acupuncture state was stronger than the resting state (P < 0.05, GRF correction). The coordinates of the peak point were (-27, -51, 48), the T value of the peak point was 5.502, and the number of voxels was 12. The variation of dynamic functional connectivity in the sensory motor network of acupuncture state was significantly lower than that in resting state( P<0.05, GRF correction), the peak point coordinates were (-5, -30, 39), the peak T value was -3.152, and the number of voxels is 9.In the control group, there was no significant difference between acupuncture state and resting state in functional connection of sensory motor network, while the difference of sensory motor network and thalamus between acupuncture state and resting state was statistically significant. The intensity of acupuncture state was lower than that of resting state ( P<0.05, GRF correction), the coordinates of peak point were (-12, 3, 6), the T value of peak point was -4.253, and the number of voxels was 183.There was no significant difference in the variation of dynamic functional connectivity in sensory motor network before and after acupuncture. Compared with the healthy control group, the functional connectivity of the experimental group was stronger than that of the healthy control group ( P<0.05, GRF correction). The coordinates of the peak point were (0, 42, 48), the T value of the peak point was 3.988, and the number of voxels was 53.The difference in the resting state of thalamus in the experimental group was weaker than that in the healthy control group ( P< 0.05, GRF correction), the coordinates of the peak point were (- 9, -15, 9), the T value of the peak point was -6.596, and the number of voxels was 101; there was no significant difference in the dynamic functional connectivity variability between the two groups, but there were scattered differences in the resting state ( P<0.05, GRF correction). With age, gender and course of disease as control variables, partial correlation analysis showed that the average functional connectivity strength in the sensory motor network of the experimental group was significantly higher than that of the Fugl Meyer assessment (FMA) of the lower limbs. There was a negative correlation between the scores of FMA. The correlation coefficient between the average functional connectivity in the sensory motor network of acupuncture state and the FMA score of lower extremity was -0.533 ( P=0.011), and the correlation coefficient between the average functional connectivity in the sensory motor network of acupuncture state and FMA score of lower extremity was -0.485 ( P=0.022). Conclusion:The brain function in acupuncture state sensorimotor network of patients with cerebral infarction is different from that in resting state, and this operation mode also has time-related fluctuation changes.

Ischemic stroke (IS) is the result of a combination of multiple risk factors, and its pathogenesis involves multiple systemic physiological and pathological changes. Recent studies have found that the activation of renin-angiotensin system (RAS) is closely related to the development of IS. In this review, we mainly summarize the generation of RAS and pathogenesis of RAS in IS.

Objective To observe the clinical efficacy of synergism of TCM medicinal oxygen therapy in treating acute cerebral infarction.Methods Eighty cases were randomly divided into treatment group and control group, 40 cases in each group, and 1 case was lost in treatment group. Based on routine treatment, the control group was treated with low flow oxygen inhalation only, while the treatment group was treated with TCM medicinal oxygen therapy. The course of treatment was 2 weeks. The two groups were scored with National Institutes of Health Stroke Scale (NIHSS) and Stroke Symptom Scale of TCM (SSTCM) before and after the course to evaluate the therapeutic effect. Results The scores of NIHSS and SSTCM in both groups after the treatment were with statistical significance (P<0.05). There was no statistical difference in the scores of NIHSS between two groups after the treatment (P=0.10). There were statistical difference in the scores of SSTCM between two groups after the treatment (P<0.05). The clinically curative effect rate in treatment group was76.9% (30/39), which was superior to that of 60.0% (24/40) in the control group, with statistical significance (P=0.27).Conclusion TCM medicinal oxygen therapy can improve the neurological deficit and enhance the efficacy.

Objective To explore the effect of acupuncture at Yanglingquan (GB 34) on white matter structure of stroke patients. Methods 6 stroke patients with left hemiplegia in recovery stage were recruited. The sham acupoint was as control, the diffusion tensor imaging (DTI) data in a 1.5 T SIEMENS scanner before and after acupuncture at Yanglingquan point was collected. Differences between the two conditions were compared with the Tract-Based Spatial Statistics (TBSS), which is one of FSL tools. Results The brain areas included left precentral gyrus, postcentral gyrus, middle temporal gyrus, inferior temporal gyrus, supplementary motor area, inferior frontal gyrus, internal capsule, fornix and bilateral inferior parietal gyrus, in which the verum acupuncture had stronger effect on fractional anisotropy (FA) than the sham acupuncture. White matter tract such as pyramidal tract, arcuate fasciculus, corpus callosum and other inter-cortex association fibers passed these brain areas. The fiber tracts and brain areas were found to be involved with multiple brain networks of motor compensation, somatosensory, language and cognition. Conclusion Compared with the sham point, acupuncture at Yanglingquan point can change the microstructure of stroke patients' white matter, mainly in the inaffected side and related to multiple functional networks.
