ABSTRACT
The quantity of mild moxibustion stimulation is an important factor affecting clinical therapeutic effect. In the present study, we collected related literature by using key word "moxibustion stimulation quantity" from CNKI Database and make a summary about its concept. The quantity of mild moxibustion stimulation has two common characters, namely thermal intensity and cumulative stimulating quantity, and contains 6 components (parameters), including thermal energy, thermal stimulus, heated area of the skin, and stimulating duration, intensity and frequency. According to the facts mentioned above, we hold that the mild moxibustion quantity actually has 3 dimensions, i．e., the duration of stimulation, the stimulating quantity of one treatment session, and the total stimulating quantity of multiple treatment sessions. Accurately grasping and rationally using the basic term of the quantity of mild moxibustion is not only conductive to control clinical moxibustion operation, but also conforms to the basic requirements for quantitative control of intervention measures in experimental researches.
ABSTRACT
Objective To observe the response of TRPV1 sensitive neurons in spinal cord under moxibustion of different temperatures in "Zusanli". Methods Totally 40 healthy male SD rats were chosen and stimulated with moxibustion at "Zusanli" in 41 ℃, 45 ℃ and 49 ℃. Extracellular recording techniques of glass microelectrode was used in the rats' L4spinal cord neurons. Capsaicin vehicle and solution was injected into the rats through "Zusanli" to filter the sensitive neuron to TRPV1. The response of sensitive neurons to TRPV1 in spinal cord under moxibustion of three different temperatures was recorded and compared. Results The TRPV1 sensitive neurons responded to all the three temperatures. Viewing from the nature of the responding neurons, the neuron in 45 ℃ and 49 ℃ mainly performed in agitation, while the number of agitated and inhibitory neurons appeared same in 41 ℃. Viewing from the character of the responding neurons, different temperatures correspond to differential discharge frequency: 41 ℃was (8.26±2.14) spikes/s, 45 ℃ was (4.69±2.61) spikes/s, 49 ℃ was (10.66±5.97) spikes/s. Viewing from the change of discharge frequency, the neurons in 41 ℃ was found without obvious change, while the neurons in 45 ℃and 49 ℃ discharge frequency apparently increased (P<0.01). Conclusion Sensitive neurons in TRPV1 in spinal cord can response to 41 ℃, 45 ℃ and 49 ℃, whose character, nature and degree are related to the temperature gradient.
ABSTRACT
After analyzing the contents of Volume Ⅲ of A-B Classic of Acupuncture and Moxibustion, we propose a concept of classical morphological view about acupoints in terms of their superficial signs and structure in Chinese ancient times. That is to say that the ancient medical experts' understanding about acupoints contain locality, layers and variability. These 3 aspects were applied to the classification and location of acupoints, as well as to the clinical treatment in the ancient times. Furthermore, the classical view about acupoints also contains the ideas of Shou-Xing (, keeping paying attention to needling the local acupoints only in the light of the focus) and Shou-Shen (, keeping paying attention to both the related acupoints and appropriate manipulations in the light of pattern identification of symptoms and signs as well as the patients' physical constitutions) in performing acupuncture treatment. Owing to the influence of the idea of Shou-Shen, the classical view about the signs and structure of acupoints presented a weakening trend gradually in ancient Chinese medical circle.
