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
OBJECTIVE: To investigate the effect of electroacupuncture(EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt(p-Akt) protein in rat myocardium after ischemia and reperfusion.METHODS: ...OBJECTIVE: To investigate the effect of electroacupuncture(EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt(p-Akt) protein in rat myocardium after ischemia and reperfusion.METHODS: Seventy Wistar rats were evenly randomized into seven groups: the sham operation group(group A), ischemia-reperfusion model Ⅰgroup(group B), ischemia-reperfusion model Ⅱgroup(group C), EA at Neiguan(PC 6) group(group D), EA at Ximen(PC 4) group(group E), EA at Hegu(LI 4) group(group F), and LY294002 + EA at Neiguan(PC 6) group(group G). All processes were monitored by electrocardiography. In group A, the left anterior descending coronary artery was only threaded without ligation for 100 min. In group B,the left anterior descending coronary artery was ligated for 40 min and reperfused for 60 min. The left anterior descending coronary artery in group C was ligated for 40 min and reperfused for 100 min.Groups D, E, and F received EA for 20 min before undergoing ischemia for 40 min, and then received EA for 20 min before undergoing reperfusion for 60 min. Before modeling, group G was injected with LY294002(0.3 mg/kg) into the tail vein, and then underwent the same intervention as the other EA groups. After reperfusion, myocardial tissue from the left cardiac ventricle was collected to enable Western blot analysis of the p-Akt level, and analysis of electrocardiographic changes.RESULTS: In groups B and C, electrocardiography showed obvious elevation of the ST-segment Ⅱlead(ECG-STⅡ), while the ECG-STⅡvalues were significantly lower in groups D, E, and G(P < 0.01). The p-Akt levels in groups D and E were significantly greater than those in groups B and C(P < 0.01).Compared with all other groups, group G showed a significantly different expression of p-Akt(P < 0.01).CONCLUSION: The expression of p-Akt protein in cardiomyocytes was significantly greater in rats that were injected with LY294002 and received EA at Ximen(PC 4) compared with all other groups.This suggests that EA at Ximen(PC 4) resulted in activation of the phosphoinositide 3-kinase/Akt signaling pathway and phosphorylation of Akt.展开更多

The intracellular microelectrode recordings from the spinal drosal horn of C5 - T1 segments were used to search and identify the spinal neurons. A total of 53 neurons responding to the stimulation of both STN and HG was recorded intracellularly. 24 and 29 of them were found to antidromically and synaptically respond to the stimulation of STN, respectively. These neurons were mainly distributed in the laminae III - Vl of spinal dorsal horn. The results indicate that (i) some spinal neurons can receive somatic afferent inputs from HG and convey them to the visceral sensory nucleus - STN; (ii) the other spinal neurons receive afferent impulse from both the STN and HG; (iii) the convergence and integration between somatic and visceral sensory inputs might occur in these spinal neurons and STN.展开更多

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

文摘OBJECTIVE: To observe the analgesic effect of acupuncture at Hegu (LI 4) in vitro fertilization-embryo transfer (IVF-ET) transvaginal oocyte retrieval using ultrasonography and explore its mechanism. 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.

文摘OBJECTIVE: To investigate the effect of electroacupuncture(EA) at acupoints on the pericardium meridian on the expression of phosphorylated Akt(p-Akt) protein in rat myocardium after ischemia and reperfusion.METHODS: Seventy Wistar rats were evenly randomized into seven groups: the sham operation group(group A), ischemia-reperfusion model Ⅰgroup(group B), ischemia-reperfusion model Ⅱgroup(group C), EA at Neiguan(PC 6) group(group D), EA at Ximen(PC 4) group(group E), EA at Hegu(LI 4) group(group F), and LY294002 + EA at Neiguan(PC 6) group(group G). All processes were monitored by electrocardiography. In group A, the left anterior descending coronary artery was only threaded without ligation for 100 min. In group B,the left anterior descending coronary artery was ligated for 40 min and reperfused for 60 min. The left anterior descending coronary artery in group C was ligated for 40 min and reperfused for 100 min.Groups D, E, and F received EA for 20 min before undergoing ischemia for 40 min, and then received EA for 20 min before undergoing reperfusion for 60 min. Before modeling, group G was injected with LY294002(0.3 mg/kg) into the tail vein, and then underwent the same intervention as the other EA groups. After reperfusion, myocardial tissue from the left cardiac ventricle was collected to enable Western blot analysis of the p-Akt level, and analysis of electrocardiographic changes.RESULTS: In groups B and C, electrocardiography showed obvious elevation of the ST-segment Ⅱlead(ECG-STⅡ), while the ECG-STⅡvalues were significantly lower in groups D, E, and G(P < 0.01). The p-Akt levels in groups D and E were significantly greater than those in groups B and C(P < 0.01).Compared with all other groups, group G showed a significantly different expression of p-Akt(P < 0.01).CONCLUSION: The expression of p-Akt protein in cardiomyocytes was significantly greater in rats that were injected with LY294002 and received EA at Ximen(PC 4) compared with all other groups.This suggests that EA at Ximen(PC 4) resulted in activation of the phosphoinositide 3-kinase/Akt signaling pathway and phosphorylation of Akt.

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.

文摘Hegu （LI 4） and Taichong （LR 3） are the Yuan- Primary acupoints of the Large Intestine and Liver Meridian, and are collectively named as Si Guan （four gates） point. Combined use of these two acupoints can harmonize yin and yang, regulate qi and blood, and balance ascending or descending. This paper attempts to study the effects of Si Guan point on the vascular dilation and constriction in migraine patients from the perspective of its feature.
文摘Epigastric pain, also known as stomach pain, is presented with fi＇equently recurrent pain in the upper abdomen or stomach area, which is mainly caused by exogenous pathogen, improper diet or internal injuries due to seven emotions. All 45 cases with epigastric pain caused by various fitctors were treated with mainly needling Hegu （LI 4） between November 2010 and November 2012, and the report is given as follows.
文摘BACKGROUND Post-operative nausea and vomiting(PONV)after cholecystectomy occurs in 40%-75%of patients,significantly affecting recovery and satisfaction.AIM To evaluate the effectiveness and safety of acupuncture at Hegu(LI4)and Zusanli(ST36)acupoints in preventing PONV in patients undergoing cholecystectomy.METHODS This retrospective study included 240 patients undergoing cholecystectomy(January 2022 to December 2023),randomized to acupuncture(n=120)or control groups(n=120).The acupuncture group received bilateral LI4 and ST36 acupuncture immediately post-surgery and 6 hours later;controls received routine care.Primary outcomes included PONV incidence,severity(visual analogue scale score),and time to first occurrence.RESULTS The total PONV incidence in the acupuncture group was significantly lower than in the control group(28.3%vs 47.5%,P<0.01).Stratified analysis showed that in the laparoscopic group,the acupuncture group’s PONV incidence was 26.7%,significantly lower than the control group’s 45.6%(P<0.01);in the open surgery group,the acupuncture group was 33.3%,lower than the control group’s 53.3%(P<0.05).The acupuncture group showed significantly reduced symptom severity(visual analogue scale score 2.7±1.4 vs 4.5±1.8,P<0.01),delayed time to first occurrence(8.4±2.1 hours vs 4.2±1.5 hours,P<0.01),with the symptom-free period extended by 4.2 hours.The acupuncture group had a higher proportion of mild symptoms(76.5%vs 35.1%)and a significantly increased proportion of symptom-free patients within 6 hours post-surgery(67.6%vs 28.1%,P<0.01).Rescue antiemetic medication usage was significantly reduced in the acupuncture group(18.3%vs 35.8%,P<0.01).Patient satisfaction scores in the acupuncture group were significantly better than the control group(4.6±0.7 vs 3.8±0.9,P<0.01),with hospital stay shortened by 0.5 days(2.1±0.8 days vs 2.6±1.1 days,P<0.05).Subgroup analysis showed that acupuncture was more effective in patients≤45 years(incidence reduction 23.5%vs>45 years group 16.8%),with significant efficacy in high-risk patients(Apfel score≥3)(36.2%vs 62.2%,P<0.01).Safety analysis showed only 7 cases(5.8%)of mild adverse reactions in the acupuncture group,all self-resolved with no serious adverse events.CONCLUSION Acupuncture at LI4 and ST36 acupoints significantly reduces PONV incidence and severity after cholecystectomy,with an excellent safety profile.This non-pharmacological intervention offers particular value for high-risk patients and those with medication contraindications.
