Functional connectivity changes during migraine treatment with electroacupuncture at Shuaigu (GB8) / 中西医结合学报

OBJECTIVE@#To investigate the changes in the functional connectivity (FC) in the right insula between migraine without aura (MWoA) and healthy controls by using resting-state functional magnetic resonance imaging (rs-fMRI), and to observe the instant alteration of FC in MWoA during electroacupuncture (EA) stimulation at Shuaigu (GB8).@*METHODS@#A total of 30 patients with MWoA (PM group) and 30 healthy controls (HC group) underwent rs-fMRI scans. The PM group underwent a second rs-fMRI scan while receiving EA at GB8. The right insula subregions, including the ventral anterior insula (vAI), dorsal anterior insula (dAI) and posterior insula (PI), were selected as the seed points for FC analysis.@*RESULTS@#Aberrant FC, including dAI with right postcentral gyrus, PI with left precuneus, was found among PM before EA (PMa), PM during EA (PMb) and HC. Meanwhile, decreased FC between dAI and the right postcentral gyrus was found in the PMa compared to the HC and PMb. Increased FC between the PI and left precuneus was found in the PMa compared to the HC and PMb. Correlation analysis showed that the FC value of the right postcentral gyrus in PMa was negatively correlated with the scores of Hamilton Rating Scale for Depression and Hamilton Rating Scale for Anxiety. The FC value of the left precuneus in PMa was positively correlated with the visual analogue scale score.@*CONCLUSION@#The alteration of FC between the right insula subregions and multiple brain regions may be an important index for MWoA. EA at GB8 was able to adjust the FC between the right insula subregions and parietal lobe, namely, the right dAI and right postcentral gyrus, and the right PI and left precuneus, thereby rendering an instant effect in the management of MWoA.

Effect of spinal manipulation on brain functional activity in patients with lumbar disc herniation / 浙江大学学报·医学版

<p><b>OBJECTIVE</b>To investigate the effects of spinal manipulation (SM) on brain functional activity in patients with lumbar disc herniation (LDH).</p><p><b>METHODS</b>Eleven patients with LDH were recruited in the study. All patients received 6 times of lumbar SM treatment and then clinical efficacy was evaluated. All patients received brain functional magnetic resonance imaging (fMRI) scans before and after SM treatment.</p><p><b>RESULTS</b>Three subjects dropped out and 8 subjects completed the study, among whom 4 cases were effective and 4 ineffective after SM treatment. The required pressure value producing the same level (VAS 50) pain was (7.43 ± 1.47) kg and (10.53 ± 0.55) kg before and after SM treatment in effective patients(P<0.05); however, there was no significant difference in ineffective patients (P>0.05). Compared to pre-treatment level, the brain functional activity in effective patients was mainly inhibited, the inhibited areas were located in the right side of prefrontal cortex and cerebellum; while the brain functional activity was generally enhanced in ineffective patients.</p><p><b>CONCLUSION</b>SM can affect the brain functional activity of patients with LDH, the inhibited areas is mainly located in prefrontal cortex and cerebellum when SM treatment is effective.</p>

The laboratorial study about relation of balance between trestle and cervical spine of cervical type spondylosis patients / 中国医疗器械杂志

When 85 cervical type spondylosis patients randomly lay on one's back and on one's right side the 8 different tresles and pillows. We survey indexes of the cervical spine anatomy, for example cervical arcs and angles of cervical spine and level line. We appraise relation of balance between different trestle or pillow and cervical spine. liquid needle-free injection, jet power, stagnation pressure
