OBJECTIVE:To take Baihui(GV20)and Fengchi(GB20)targeting inflammatory response to regulate migraine as an example to describe a new method for studying the mechanism of stimulating acupoints.METHODS:The target information of Baihui(GV20)and Fengchi(GB20)was retrieved,and after intersection with migraine,Kyoto Encyclopedia of Genes and Genomes(KEGG),Reactome,and Uni Prot Keywords were used for functional enrichment.After selecting the main pathway,rats were selected and nitroglycerin was used for modeling,and the behavioral scores,inflammatory factors,heme oxygenase 1(HMOX1),protein kinase B(AKT1),signal transducer and activator of transcription 3(STAT3),phosphorylated extracellular signal-regulated kinase 1/2(P-ERK1/ERK2)and other states of the rats in the acupuncture,twisting,and electroacupuncture groups were compared.RESULTS:A total of 135 Baihui(GV20)targets and 27 Fengchi(GB20)targets were collected.A total of 73 target information were obtained after the intersection of these targets in migraine.These 73 targets have three main pathways:hypoxia-inducible factor 1(HIF-1)signaling pathway,signaling by interleukins and inflammatory response.The main targets in the pathway were verified and found that interleukin-1 beta(IL-1β),interleukin-6(IL-6),tumor necrosis factor-alpha(TNF-α)and HMOX1,AKT1,STAT3,P-ERK1/ERK2 can be regulated by Baihui(GV20)and Fengchi(GB20).CONCLUSION:Baihui(GV20)and Fengchi(GB20)can regulate migraine by regulating inflammatory factors and HMOX1,AKT1,STAT3,P-ERK1/ERK2 and other changes in HIF-1 signaling pathway,Signaling by Interleukins and Inflammatory response pathways.Based on systems biology and network pharmacology,and with the model of"acupoint-target-disease",explore the research methods of systematic acupuncture and moxibustion.We believe this is a usable research direction for exploring the mechanism of acupuncture stimulation. 展开更多

Objective To explore the possibility of infrared objective display of the heat-sensitive (HS) acupoint. Methods In 79 cases of lumbar intervertebral disc protrusion (LIDP) patients, infrared thermograms of the lumbar and back region were taken with a thermal texture maps(TTM) method at a natural state, followed by a heat-sensitive detection with moxibustion method [moxibustion was given at Yaoyangguan (腰阳关GV 3) area for 10 min]. The cases with thermal diffusion and heat transfer on the Yaoyangguan (腰阳关GV 3) area were recorded after ceasing of the suspended moxibustion. Then the infrared thermograms were taken by TTM for the second time, and the changes of infrared thermograms of the waist-back region before and after moxibustion were recorded. Finally, the differences between moxibustion and infrared detection methods in the heat-sensitive state on Yaoyangguan (腰阳关GV 3) area were compared in the LIDP patients. Results Before moxibustion, the infrared radiation intensity most displayed high-temperature characteristics on the Yaoyangguan (腰阳关GV 3) area in the LIDP patients. Compared with the moxibustion method, the sensitivity(true positive rate) was 86.4%, the specificity (true negative rate) was 70.0%, and the accuracy was 82.3%; after moxibustion at the Yaoyangguan (腰阳关GV 3) area, the infrared radiation enhanced area obviously extended vertically along the medial waist-back (the Governor Vessel) or horizontally along the Belt Vessel. Compared with the moxibustion method, the sensitivity (true positive rate) was 79.7%, the specificity (true negative rate) was 75.0% and the accuracy was 78.5%. Conclusion The HS state of Yaoyangguan (腰阳关GV 3) area in the LIDP patients can be objectively displayed by the infrared imaging to a certain extent; moxibustion at the HS acupoint produces the thermal phenomena, such as thermal expansion and heat transfer, which can be objectively displayed to a certain extent by the infrared imaging apart from the subjective feeling of the subject. 展开更多

Objective To explore the efficacy of acupuncture at Sish4nc6ng (四神聪 EX- HN 1) and Baihui (百会 GV 20) as well as the possible mechanism. Methods Eighty cases of insomnia patients treated in our hospital were selected, and randomly divided into a control group and a treatment group according to the random number table method. Conventional treatment was carried out in the control group by giving cliazepam tablets, and acupuncture at EX-HN 1 and GV 20 was conducted in the treatment group. The sleep time and quality, PSQI score, and the level changes of blood glutamic acid (GLU), y-aminobutyric acid (GABA), norepinephrine (NE) and dopamine (DA) were compared in the patients in each group before and after treatment. Results Compared with the results before treatment, the time for falling asleep of the patients in the two groups shortened (both P〈0.05), the levels of GLU and GABA increased (all P〈0.05), the sleep time was longer (both P〈0.05), and the levels of NE and DA, as well as the PSQI score reduced (all P〈0.05). Compared with the control group, the levels of NE and DA, as well as the PSQI score of patients in the treatment group reduced after treatment (P〈0.05), the time for falling asleep shortened (P〈0.05), the levels of GLU and GABA increased (P〈0.05), and the sleep time was longer (P〈0.05). Conclusion Acupuncture at EX-HN 1 and GV 20 can prolong the sleep time, improve the sleep quality, and the clinical efficacy is superior to that of western medicine treatment. The mechanism may be related to the synthesis and release of amino acids neurotransmitters. 展开更多

Objective To investigate the immunologic mechanism of acupuncture at Bǎihuì(百 会 GV 20) and Zúsānlǐ(足三里 ST 36) for treatment of depression. Methods Eighty-four cases of depression patients were randomly divided into an electroacupuncture observation group(group A), an electroacupuncture control group(group B) and a medication control group(group C), 28 cases in each group. Bǎihuì(百会 GV 20) and Zúsānlǐ(足三里 ST 36) were used in the group A; Tàichōng (太冲 LR 3), Sānyīnjiāo (三阴交 SP 6), Nèiguān (内关 PC 6) and Shénmén (神门 HT 7) were used in the group B; and the group C was treated with oral administration of Fluoxetine. The scores of Hamilton Depression Scale (HAMD) were tested and the level of serum interleukin 1(IL-1β), interleukin 6 (IL-6), and tumor necrosis factor α (TNF-α) were measured by Enzyme Linked Immunosorbent Assay (ELISA)before and after treatment. Results Their scores of HAMD were obviously decreased after treatment in three groups(all P0.01). In the group A, 2 cases were cured, 19 cases were markedly effective, 5 cases were effective and 2 cases were failed. In the group B, 16 cases were markedly effective, 12 cases were effective. While in the group C, 1 case was cured, 17 cases were markedly effective, 7 cases were effective and 3 cases were failed. The grade distribution of clinical effect showed that the effect of group A was better (P0.05). The levels of serum IL-1β and IL-6 in the three groups were obviously decreased after treatment (P0.05, P0.01), while there was no significant difference between the level of serum TNF-α before and after treatment. Conclusion The effect of electroacupuncture observation group is superior to those of electroacupuncture control group and medication control group.All of these three methods can clear the inflammatory cytokines such as IL-1β and IL-6 away and improve the symptoms of depression. 展开更多
