RESUMO
The neuroanatomical basis of meridian effects is one of the focuses of acupuncture mechanism studies. Meridian effects depend mainly on the generation, conduction, integration and output of acupuncture information in the acupoint, spinal cord and brain.The neural tracer technique is a basic method in neurobiology. This article presents recent years' advances in the application of the neural tracer technique to acupuncture field and summarizes the types of neural tracer used in acupuncture studies and regularities in the distribution of neurons and their fibers related to labeled meridians and acupoints in spinal segments and brain regions to provide methodological reference for studies on neurobiological mechanism of acupuncture effects.
RESUMO
Objective To detect the doubling time of airway smooth muscle cells of human and rat by the xCELLigence in-strument,a real time cellular analyzer.Methods The airway smooth muscle cells were separated by collagenase-pancreatin digestion from the rat airway.Then,added to the different holes of E-plate of xCELLigence instrument with the planting destiny of 3 000 cells/well.and so were the human airway smooth muscle cells.The E-plate was then placed on the xCELLi-gence instrument to monitor cell proliferation for 100 hours to calculate the doubling time by using the RTCA Software Package 2.0 software.Results The doubling time of human airway smooth muscle cell calculated by the real time cellular analyzer was 23.96±0.47 h,which was consistent with the data provided by the reference.The doubling time of rat airway smooth muscle cell was 18.62±0.15 h,and the computational process was simple,time-saving and also effective.Conclusion The xCELLigence instrument can be used to calculate doubling time of airway smooth muscle cells of human and rat, which provides experimental methods and reference data for the basic respiratory disease research.
RESUMO
Point Dingchuan (Ex-B1) pertains to extraordinary points and often produces a good therapeutic effect on respiratory system diseases. Ancient Chinese medical books do not record point Dingchuan. Modern Chinese medical textbooks describe the location and efficacy of and indications for this point but do not state their provenances. In order to further popularize the clinical application of point Dingchuan, this article verifies the origin and development of the name and location of point Dingchuan so as to provide a certain reference for clinically correct selection and use of this point. The results show that point Dingchuan followed the course of development from ashi point to new point and then to extraordinary point. The development of point Dingchuan to the same acupoint name and location as now international use went mainly through four stages, that is, similar name and different location, similar name and location, same name and different location, and same name and location.
RESUMO
Objective: To observe the influence on IL-1β and IL-2 in rat models with rheumatoid arthritis after moxibustion on Shenshu (BL 23) and Zusanli (ST 36) points, and to discuss the mechanism of moxibustion. Methods: Fifty male Wistar rats were divided randomly into 5 groups,control group, model group, drug group, moxibustion group, and laser group, 10 for each. Four groups except the normal group were built on the model of rheumatoid arthritis. The changes of body weight and plantar circumference were measured and the level of IL-1β、 IL-2 in sera were examined by ELISA. Results: Compared with the model group, the weight and plantar circumference of rats in the moxibustion group were improved significantly after treatment (P<0.01), and the improvement of plantar circumference also had significant differences compared with the drug group and the laser group (P<0.05). The level of IL- 1β、 IL-2 in sera were down regulated in the moxibustion group and the laser group, which had statistical differences compared with the model group (P<0.05), but no statistical differences were found when comparing with the drug group. Conclusion: Moxibustion obviously improves the toe tumefaction of the rats with rheumatoid arthritis, which is better than CO2 laser of 10.6μm. On the aspect of decreasing the amount of IL-1β、 IL-2, CO2 laser of 10.6 μm is similar with moxibustion.
RESUMO
Objective: To identify the differential proteins in the serum with anti-asthma activity of acupuncture to pinpoint the substance basis of anti-asthma activity of acupuncture by proteomics method. Methods: Two-dimensional electrophoresis of protein was employed to analyze the differential proteins in the serum with anti-asthma activity of acupuncture, and identify the differential proteins with mass spectrum technique. Results: In adrenalectomy (ADX)-asthma acupuncture group and asthma acupuncture group, two-dimensional electrophoresis showed that there was an obvious fuscous point (MW=44.1kD, PI=5.1), which was 60S ribosomal protein L13, or hypothetical protein FLJ32191 analyzed by mass spectrum technique, different from other groups. In ADX-asthma acupuncture group, there were two obviously fuscous points (MW=39.SkD, PI=4.9 and MW=39.SkD, PI=5.0), which were zinc finger protein 208, and thyroid hormone receptor-associated protein analyzed by mass spectrum technique, and two special proteins (MW=17.3kD, PI<4.5 and 16.9kD, PI<4.5), which were Cyclophilin A and zinc finger protein 91 analyzed by mass spectrum technique, different from other groups. Conclusion: There are multi-target effects regulating the whole body in acupuncture treating asthma relating to immunoloregulation, gene expression, and protein synthesization. The effects of acupuncture on the response proteins need further research.
