Bilateral Taichong（LR3） was treated by acupuncture using different manipulations and manual stimulation. Reinforcing twirling, reducing twirling, and needle retaining resulted in a decreased number of apoptotic cells, reduced Bax m RNA and protein expression, and an increased Bcl-2/Bax ratio in the hippocampus compared with the SHR group. Among these groups, the Bcl-2/Bax protein ratio was highest in the reducing twirling group, and the Bcl-2/Bax m RNA ratio was highest in the needle retaining group. These results suggest that reinforcing twirling, reducing twirling, and needle retaining methods all improve blood pressure and prevent target organ damage by increasing the hippocampal Bcl-2/Bax ratio and inhibiting cell apoptosis in the hippocampus in SHR.展开更多

Methods Thirty-eight patients with cardiac neurosis were selected for treatment through acupuncture at PC 6 in combination with respiratory reinforcing and reducing method. With twice per day, treated for 6 days per week, and 4 weeks as one course, the therapeutic effect was assessed after one course. Results Twenty-one cases were cured, 15 cases were remarkably improved, and 2 cases were failed. The total effective rate was 94.7%. Conclusion Acupuncture at PC 6 in combination with respiratory reinforcing and reducing method is effective in treatment of cardiac neurosis.展开更多
