[Effect of moxibustion on Nogo/neurotrophin receptor signaling pathway in rats with cerebral ischemia/reperfusion injury].

OBJECTIVE: To observe the effect of moxibustion treatment on the expression of Nogo-A, Nogo receptor (NgR), neurotrophin receptor p75 (p75NTR) and leucine rich repeat and Ig domain containing 1 (Lingo-1) in brain tissue of rats with cerebral ischemia/reperfusion injury (CI/RI), so as to analyze its mechanism underlying improvement of CI/RI. METHODS: Male SD rats were randomly divided into sham operation group (16 rats), model group (17 rats), NEP1-40 (extracellular peptide residues 1-40, a blocker targeting NgR) group (model+blocker, 17 rats) and moxibustion group (model+moxibustion, 17 rats). The CI/RI model was established by occlusion of the left middle cerebral artery (MCAO). Moxibustion was applied to "Baihui"(GV20), right "Quchi"(LI11) and "Zusanli"(ST36) for 20 min, once a day for 14 days, with 2 days' rest after the top 7 days' intervention. For rats of the NEP1-40 group, 30 µL PBS containing 18 µg NEP 1-40 was injected into the epidural inferior vena (L5-S1) via a polyvinyl chloride conduit. The neurological deficit state in each group was evaluated by Longa's 5-point scale and Feeney's 7-point scale of beam walking test (BWT). The cerebral infarct volume was assessed by 2,3,5-triphenyltetrazole chloride staining. The brain tissue between the central anterior and posterior sulcus was taken for observing the expression of NgR and Lingo-1 by fluorescence double-label method, and for determining the expression levels of Nogo-A, NgR, p75NTR and Lingo-1 mRNAs and proteins by real-time quantitative PCR and Western blot, respectively. RESULTS: After modeling, the Longa's score, infarct volu-me percent, expression levels of Nogo-A, NgR, Lingo-1 and p75NTR mRNAs and proteins were significantly increased (P<0.01) and BWT score was obviously decreased (P<0.01) in the model group relevant to the sham operation group. In comparison with the model group, the increase of Longa's score, infarct volume percentage, expression levels of Nogo-A, NgR, Lingo-1 and p75NTR mRNAs and proteins and decrease of BWT score in NEP1-40 and moxibustion groups were reversed (P<0.01) except Nogo-A protein in the NEP1-40 group. The effect of moxibustion was significantly superior to that of blocker NEP1-40 in redu-cing the infarct volume percentage, and down-regulating the expression of Nogo-A mRNA and protein, p75NTR mRNA and protein, NgR and Lingo-1 proteins (P<0.01, P<0.05). CONCLUSION: Moxibustion, similar to blocker NEP1-40 of NgR, can improve neurological dysfunction in CI/RI rats, which may be related to its functions in reducing cerebral infarction and down-regulating the activity of Nogo/neurotrophin receptor signaling pathway.

[Thermosensitive Moxibustion Induces A Better Therapeutic Effect in the Treatment of Facial Paralysis Patients].

OBJECTIVE: To compare the effect difference between the thermosensitive moxibustion (TSM) and conventional mild moxibustion (CMM) at Yifeng (TE 17) plus acupuncture intervention in the treatment of facial paralysis patients. METHODS: The prospective cohort study design was used in the present study. A total of 183 patients were divided into a thermosensitive moxibustion (regional heat penetrating, heat extending, warmer in deep-tissue, etc.) group (n＝132) and a CMM group (n＝51) according to the patients' subjective feeling to moxibustion stimulation of TE 17. After propensity score matching (PSM, a statistical matching technique of observational data) processing by using SPSS 19. 0 software, outcomes of 33 cases in the TSM group and 33 cases in the CMM group were analyzed. In the 1st course (10 days) of treatment, TSM was applied to TE 17 till the thermosensitive feelings disappeared for patients in the TSM group, or CMM employed to TE 17 for 45 min for patients in the CMM group, followed by manual acupuncture stimulation of Cuanzhu (BL 2), Yangbai (GB 14), Sibai (ST 2), Quanliao (SI 18), Jiache (ST 6), etc. on the affected side (shallow needling, uniform reinforcing-reducing needle-manipulation) for 30 min, once daily. In the 2nd course (10 days), only manual acupuncture was performed, the same acupoints were stimulated with the same methods used in the 1st course, and in combination with bilateral Zusanli (ST 36) which was stimulated with reinforcing-needling technique. The interval between the 2 courses was 2 days. The modified Portmann scale (for movements of eyebrow raising, eye closing, cheek bulging, pouting, teeth showing and nostril widening, and symetry during resting state) was used to evaluate the severity of the facial palsy before and after the treatment. RESULTS: After the treatment, the Portmann scores were significantly higher than those of their own pre-treatment in each of the two groups (P < 0.01), being markedly higher in the TSM group than in the CMM group (P < 0.01), suggesting a better therapeutic effect of TSM. CONCLUSION: The thermosensitive moxibustion is considerably superior to the conventional mild moxibustion in improving the symptoms of facial paralysis patients.

[Exploration on sensation positioning method of heat-sensitive moxibustion: the inheritance and development of ashi method].

From original concept and literature of acupoint, the concept and clinical significance of ashi method is discussed, which clarifies that the essence of ashi method is to locate the acupoints by patients' sensitivity on force. The clinical application of heat-sensitive moxibustion has illustrated that positioning method of this therapy is based on the appearance of heat-sensitive moxibustion sensation. Although both types are based on patients' feeling, positioning method of heat-sensitive moxibustion stands on a new angle and uses a new method to locate acupoint. Therefore, it is believed that the positioning method of heat-sensitive moxibustion is the inheritance and development of ashi method.
