ABSTRACT
We summarized our accumulated clinical and teaching experiences and explored the regularity of acupuncture needling and teaching. It is of great importance in pressing hand during inserting needle. Stroking and pressing are two crucial parts which deserve more attention, and seldom useage of pressing hand should be abolished. Operating hand needs practice before inserting needle, while it should fully relaxed during inserting. Blending "touching", "stretch" "gathering" "erupting" and "advancing" in single moment, applying appropriate dynamic mode of inserting needle such as "join 3 forces as one" "3 points in a line" expertly and naturally. In addition, enough attention should be paid on "altering direction" and "shifting point". Inserting deftly and powerfully, no/slight sensation, deqi when inserting needle are the highest reflection as an acupuncturist.

<p><b>OBJECTIVE</b>To explore the protective mechanism of acupuncture on myocardial ischemia-reperfusion injury.</p><p><b>METHODS</b>Fifty Wistar rats were randomly divided into a sham-operation group, a model group, a Jiaji group , a Neiguan group and a Yanglingquan group, 10 rats in each group. The model of myocardial ischemia-reperfusion injury was duplicated by ligating the left anterior descending coronary artery (LADCA) in the later four groups, and the LADCA was not ligated in the sham-operation group. The rats in the treatment groups were treated with electroacupuncture at "Jiaji" (EX-B 2), "Neiguan" (PC 6) and "Yanglingquan" (GB 34) on both sides, respectively, once a day for 7 days. No interventions were produced in the sham-operation group and model group. Myocardial apoptosis were examined by the TUNEL method. The expressions of Bcl-2 and Bax proteins were measured by immunohistochemical method.</p><p><b>RESULTS</b>Apoptosis index(AI) was significantly lower in the Jiaji group, Neiguan group and sham-operation group compared with model group (P < 0.01). Compared with the sham-operation group, AI were significantly increased in other groups (all P < 0.01). There was no significant difference in AI between Jiaji and Neiguan group (P > 0.05). Compared with the model group, the expression of Bcl-2 was significantly increased and Bax protein was significantly decreased in Jiaji group and Neiguan group (both P < 0.01). The expressions of Bcl-2 and Bax proteins were significantly increased in other groups compared with the sham-operation group (all P < 0.01). There was no significant difference in the expression of Bcl-2 and Bax proteins between Jiaji and Neiguan group (P > 0.05).</p><p><b>CONCLUSION</b>Electroacupuncture at both Jiaji (EX-B 2) and Neiguan (PC 6) has protective effects on myocardial ischemia-reperfusion injury, and the mechanism is closely related to inhibiting myocardial apoptosis by adjusting the expression of Bcl-2 and Bax.</p>
