Methods: EA was applied at volunteers' right LI4 (of 9 subjects in the LI4 group) and facial non-acupoint points (of 5 subjects in the control group), and whole brain 3-dimensional T1 anatomical imaging of high resolution 1 × 1 × 1 mm^3 used was performed with clustered stimulatory mode adopted by BOLD fMRI. Pretreatment and statistical t-test were conducted on the data by SPM2 software, then the statistical parameters were superimposed to the 3-dimensional anatomical imaging. Results: Data from 3 testees of the 9 subjects in the LI4 group were given up eventually because they were unfit to the demand due to different causes such as movement of patients' location or machinery factors. Statistical analysis showed that signal activation or deactivation was found in multiple cerebral areas in 6 subjects of LI4 group and 5 subjects of the control group (P〈0.01). In the LI4 group, the areas which showed signal activation were: midline nuclear group of thalamus, left supra marginal gyrus, left supra temporal gyrus, right precuneous lobe, bilateral temporal pole, left precentral gyrus and left cerebellum; those which showed signal deactivation were: bilateral hippocampus, parahippocampal gyrus, amygdala body area, rostral side/audal side of cingulate gyrus, prefrontal lobe and occipital lobe as well as left infratemporal gyrus. In the control group, areas which showed signal activation were: bilateral frontal lobe, postcentral gyrus, Reil's island lobe, primary somato-sensory cortex, cingulate gyrus, superior temporal gyrus, occipital cuneiform gyrus and/or precuneus gyrus and right brainstem; and the area that showed deactivation was left median frontal lobe. Conclusion: The effects of EA LI4 in regulating cerebral activities could be displayed and recorded through BOLD fMRI, the distribution of signally deactivated area evoked by EA LI4 was similar to the known distribution of anatomical orientation of pain in brain, and closely related to the anatomic structure of limbic system, which areas are possibly the acupuncture analgesic effect's cerebral regulating area. Furthermore, activated portion of left central anterior gyrus, which represent the movement of oral facial muscles, and the activated portion of cerebellum are possibly related with the effect of using EA LI4 in treating facial palsy and facial muscle spasm. As for the mechanism of signal deactivation of cerebral activities exhibited in the present study that is unable to be elucidated, it awaits for further research.展开更多

METHODS: Ninety patients undergoing IVF-EF oocyte retrieval were randomly divided into three groups: an acupuncture group with needles inserted into bilateral Hegu (LI 4) points, a placebo group given placebo needles, and a control group with routine oocyte retrieval. Each group had an indometacin enema 30 min before the operation. We compared the pain-rated index (PRI), visual analogy scale (VAS), and present pain intensity (PPI) immediately after operation and 1 h after operation. We also determined the neuropeptide Y (NPY) level of the follicular fluid. RESULTS: PRI, VAS, and PPI after operation and 1 hafter operation in the acupuncture group were significantly lower than those in the control group (P< 0.01). No obvious difference (P>0.05) was observed in PRI,VAS, and PPI after operation and 1 h after operation between the placebo group and the control group.The NPY level of the follicular fluid in the acupuncture group was significantly higher than that in the control group (P<0.01). No obvious difference (P>0.05) was observed in the NPY level of the follicular fluid between the placebo group and the control group. CONCLUSION: The analgesic effect of acupuncture at Hegu in transvaginal oocyte retrieval using ultrasonography may be related to the increase in the NPY level of the follicular fluid.展开更多
