[Acupuncture-moxibustion and mitogen-activated protein kinase signal transduction pathways].

The Literatures on mechanism of acupuncture from the aspect of mitogen-activated protein kinase (MAPK) signal transduction pathways are analyzed in this paper. And the result shows that many acupuncture effects are closely related with the regulation of MAPK signal transduction pathway. However, the current studies only cover limited aspects, and there problems still existed in the experiment designation.

[Effects of electroacupuncture on expression of calmodulin in the hippocampus of rats with cerebral ischemia-reperfusion injury].

Objective: To investigate the protective effect of electroacupuncture (EA) on injured neurons and the signal transduction mechanism of calmodulin (CaM) in rats with cerebral ischemia-reperfusion injury (CIRI).

Methods: A total of 25 SD rats were randomly divided into a sham-operation group, a model group, an EA. group, a TFP group and an EA+TFP group.

[Progress of studies on effects of acupuncture on cellular signal transduction].

In order to elucidate the underlying mechanism of acupuncture in regulating different physiological functional activities at cellular level, abundant researches have been conducted on cellular signal transduction activities. The present article preliminarily analyzes acupuncture stimulation induced various cellular signaling pathways from the afferent physical signals of the regional mechanical stimulation at the acupoint, activation of receptors of the cellular membrane such as Guanine nucleotide binding protein coupled receptors, etc., intracellular second messenger molecules including cAMP, Ca2+, inositol triphosphate, diacyl glycerol, etc.

[Survey of research on acupoints compatibility].

The research papers that meet the criteria of evidence-based medicine and randomized controlled trial were retrieved in Chinese journals data bases (CNKI knowledge network) from 1992 to 2009. Twenty-five papers indicate that acupoints compatibility rules are closely related to organism regional anatomy, nerve, the blood vessel and the endocrine gland; acupoints compatibility rules produce synergism, inhibit or antagonistic effect that affect the clinical effectiveness. The acupoints compatibility rules based on experimental researches are applied to clinic practice is the key to improve the acupuncture clinical effectiveness.

[Effect of electroacupuncture on hippocampal LTP in Alzheimer' s disease rats induced by Abeta(25-35)].

Objective: To observe the effect of electroacupuncture(EA) on the learning-memory ability in Alzheimer's disease(AD) rats.

Methods: Thirty SD rats were equally randomized into control, model and EA groups. AD model was established by injecting beta-amyloid (Abeta(25-35), 10 microg) into the bilateral dentate gyri of the hippocampal CA 1 area (AP--3.

[Effect of electroacupuncture on cerebral cortex ultrastructure in rats with cerebral ischemia-reperfusion injury].

Objective: To observe the effect of electroacupuncture (EA) of "Baihui" (GV 20) and "Dazhui" (GV 14) on the ultrastructure of cerebral cortex in rats with cerebral ischemia reperfusion (CI/R) injury.

Methods: Fifteen SD rats were equally randomized into sham-operation (sham), model and EA groups. CI/R model was established by right middle cerebral artery occlusion for 1 h and reperfusion for 24 h.

[Involvement of melatonin in the adjusting effect of electroacupuncture in resisting oxygen stress in cerebral ischemia-reperfusion injury rats].

Objective: To explore the effect of electroacupuncture (EA) in resisting acute cerebral ischemia-reperfusion injury (CI-RI) via anti-oxidation of melatonin (MT).

Methods: A total of 52 male SD rats were randomized into Sham-operation (sham, n=8), CI-RI (model, n=8), EA (n=8), MT (3.2 mg/Kg, i.

[Clinical experiences and thinking of acupuncture for treatment of some difficult and complicated eye's diseases].

The present paper introduces author's some successful experiences on acupuncture treatment of some difficult and complicated eye's diseases in recent years. The author has systematically studied on the law and acupoints of acupuncture for treatment of some difficult and complicated eye's diseases, and worked out therapeutic principles and selected acupoints by means of syndrome differentiation, treating both the principal and the second aspects of a disease, its symptoms and cause at the same time, selecting acupuncture points according to syndromes, combination of Chinese medicine with western medicine, combination of acupuncture with medicine, etc. to strengthen the body resistance and eliminate pathological factors, attaining very satisfactory clinical therapeutic effects.

[Clinical observation on mild-warm moxibustion for treatment of diabetic peripheral neuropathy].

Objective: To observe clinical therapeutic effect of mild-warm moxibustion on diabetic peripheral neuropathy (DPN) and to probe the mechanism.

Methods: Sixty cases of DPN were randomly divided into a mild-warm moxibustion group, an acupuncture group and a medication group, 20 cases in each group. In the mild-warm moxibustion group and the acupuncture group, the same points, Shenshu (BL 23), Pishu (BL 20), Zusanli (ST 36), Yongquan (KI 1), etc.

[Application of TC index location on Longa' s animal model of regional experimental cerebral ischemia and reperfusion].

Objective: To study the TC index location on a reform LONGA' s animal model of regional experimental cerebral ischemia and reperfusion.

Methods: A total of 300 SD male rats were randomly divided into the pre-test group (n = 30), the original method group (n = 120, Longa' s method) and the reform method group [ n = 150, TC index location is defined by the length of rat incisor teeth root (T point) to the common carotid artery bifurcation (C point) ,the blood flow of a unilateral middle cerebral artery in the rats was reversibly blocked by the TC index location). The morphologic changes and the successful rate of the two methods to establish the rat model were compared.

Progress in researches on the effect of acupuncture in antagonizing oxygen stress.

Oxidation and free radicals participate in the pathological process of multiple diseases in organisms, and acupuncture shows good effect in antagonizing oxygen stress (OS). This article reviews the effect of acupuncture in antagonizing oxygen stress and the mechanism of its anti-free radical effect in various diseases. The authors hold that acupuncture not only has a chain-blocking effect, but also has preventive and repairing effects of anti-oxidation.
