Clinical Application of Acupoint Neiguan （PC 6）

Acupoint Neiguan （PC 6） is first recorded in Ling Shu （Spritual Pivot）. It is the Luo-Connecting point of the Pericardium Meridian and communicates with acupoint Waiguan （TE 15）; it is also one of eight confluent points, and associates with the Yin Link Vessel. We often use Neiguan （PC 6） alone or as the cardinal acupoint to treat many disorders in clinical practice. It is now reported as follows.     

Acupressure and vitamin B6 to relieve nausea and vomiting in pregnancy: a randomized study

Objective To compare the effectiveness of acupressure and vitamin B6 in the outpatient treatment of nausea and vomiting in early pregnancy. Study design Pregnant volunteers with symptoms of mild to moderate nausea and vomiting between 6 and 12 weeks’ gestation participated in a 7-day clinical trial. Participants were randomly assigned to receive a device for acupressure therapy and placebo drug or an otherwise identical but non-stimulating placebo device and vitamin B6. The primary outcome measure was self-recorded symptoms according to Rhodes index. Secondary outcome measures were weight gain and medication use. Results The mean change in Rhodes index was not significantly different between the two groups. There were no statistically significant differences in weight gain and medication use between the two groups. Conclusion Acupressure therapy is not more effective than vitamin B6 in reducing nausea and vomiting in symptomatic women in the first trimester of pregnancy.     

艾灸疗法对急性失血性休克家兔血压及心泵功能的影响

电针内关、建里治疗抑郁症的临床研究

目的观察电针内关、建里治疗抑郁症的临床疗效。方法选取门诊及住院轻中度抑郁症患者45例，以内关、建里为主穴进行电针治疗。结果治疗前后自身对照，汉密尔顿抑郁量表评分有显著性差异（P〈O．05），总有效率达88．1％。结论电针内关、建里治疗抑郁症有一定疗效且比较安全。     

电针、复方丹参滴丸、针药结合对冠心病患者心肌耗氧量和临床症状积分的对照研究

目的找出针、药及针药结合三者的最佳治疗方法,并为电针手厥阴心包经内关穴对冠心病心肌缺血患者具有良好的调整作用提供临床依据。方法通过电针内关穴、口服复方丹参滴丸及针药结合等3种不同治疗方法对冠心病心肌缺血患者心肌耗氧量和临床症状积分的改变进行客观疗效比较。结果3种不同治疗方法均能降低心肌耗氧量(P<0.01),缓解心绞痛,减轻临床症状,降低临床症状积分(P<0.01),提高疗效;3组比较,针药组>电针组>药物组。结论单纯运用电针和口服复方丹参滴丸治疗冠心病患者均有较好的疗效,但针药结合运用效果更好。电针手厥阴心包经内关穴对冠心病心肌缺血患者具有良好的调整作用。     

电针"内关"对充血性心力衰竭大鼠Ang Ⅱ,ET,CGRP影响的实验研究

目的:观察电针"内关"治疗充血性心力衰竭大鼠(CHF)血浆中血管紧张素Ⅱ(Ang Ⅱ),内皮素(ET),降钙素基因相关肽(CGRP)含量的变化,并与西药卡托普利进行疗效比较,从神经体液调节角度分析针刺抗CHF的作用机制.方法:复制CHF大鼠模型,电针"内关"穴治疗及卡托普利灌胃治疗两周后,用放射免疫法测定模型大鼠血浆中Ang Ⅱ,ET,CGRP含量.结果:电针"内关"和卡托普利灌胃治疗均可明显降低模型大鼠中Ang Ⅱ和ET的含量(P＜0.05),显著升高CGRP含量(P＜0.05).两种治疗方法对Ang Ⅱ,ET,CGRP含量的影响差异不显著.结论:电针"内关"能显著降低充血性心力衰竭大鼠模型Ang Ⅱ,ET含量,而升高CGRP含量,而电针"内关"治疗与卡托普利治疗效果无显著差异(P＞0.05),可一定程度替代或作为西药治疗的有益补充,神经体液调节可能是其发挥治疗作用的机制之一.     

Effect of different LLLT on pituitrin-induced bradycardia in the rabbit

The objective of this paper was to observe the effect of low-level combined- or single-laser irradiation on bradycardia produced by pituitrin in rabbits. A combined-laser apparatus was made. A 10.6-μm CO₂ laser and a 650-nm semiconductor laser, transmitted by different optical fibers, converged to output and irradiate on the Neiguan (PC6) acupuncture point in rabbits with bradycardia produced by pituitrin. Thirty minutes after the model was set, the heart rates of the combined-laser Neiguan group made quicker recoveries than those of the model control group, the laser-control group, or the single-laser Neiguan group (P<0.05), and the heart rates of the single-CO₂-laser Neiguan group were similar to those of the normal group (P>0.05). However, there were significant differences between the 650-nm-laser Neiguan group and the normal control group (P<0.05). The combined-laser irradiation certainly has a curative effect on bradycardia produced by pituitrin. A single CO₂ laser could accelerate the recovery from bradycardia, while single 650-nm-laser irradiation on the Neiguan acupoint does not produce such an effect.     

"内关""神门""心俞"间协同作用与拮抗作用实验研究

目的：探讨作用相似的腧穴间是否存在协同或拮抗作用。方法：选用乌头碱诱发的家兔室性心律失常模型,以心律失常持续时间为指标,观察“内关”、“神门、、“心俞”单用及合用后的疗效差异。结果：“内关”、“神门”、“心俞”单用有显著疗效,且作用相近,合用后疗效无显著提高或下降。结论：作用相似且作用强度相近的腧穴间不易出现拮抗作用,但也不一定能产生显著的协同作用。     

电针内关对心肌缺血再灌注损伤大鼠cTnT及bax基因表达的影响

目的通过研究电针内关对心肌缺血再灌注损伤过程中肌钙蛋白T(cTnT)及细胞凋亡调控基因bax的影响,阐明电针内关对心肌缺血再灌注损伤的作用机制。方法在大鼠冠状动脉左前降支根部穿线结扎建立心肌缺血再灌注损伤模型,电针内关穴,检测血清中cTnT含量、分析凋亡细胞基因bax的表达。结果内关穴组血清中cTnT含量低于模型组(P<0.01);模型组bax蛋白表达的阳性率明显增高,电针内关组阳性表达率明显降低,与模型组比较有非常显著性意义(P<0.01)。结论电针内关穴可减少心肌缺血再灌注损伤过程中cTnT的释放,且对凋亡的调控基因bax的生成有抑制作用,从而在一定程度上对心肌缺血再灌注损伤心肌起到保护作用。
