[Objective] To investigate the therapeutic effect of Guanxin No. 1 Recipe (mainly composed of Radix Codonopsis, Radix Ophiopogonis, Fructus Schisandrae Chinensis, Rhizoma Polygonati Odorati, Rhizoma Chuanxiong, Rhizoma Anemarrhenae, Radix Salviae Miltiorrhizae, Radix Notoginseng, Radix Curcumae) for coronary heart disease (CHD) with angina pectoris (AP) and to observe its influence on blood lipid and hemorrheology indexes. [Methods] Eighty-eight patients with AP were allocated to group A (n = 48) and group B (n = 40) according to random number table. The two groups were given isosorbide dinitrate, Metoprolol Tartrate Tablets and enteric-coated aspirin tablets, and group A was treated with Guanxin No. 1 Recipe additionally. Four weeks constituted one treatment course. The effects on TCM syndromes, AP, electrocardiogram (ECG) and symptoms scoring, as well as on blood lipid level and hemorrheology indexes were observed before and after treatment. [Results] After treatment, the effects on TCM syndromes, AP, electrocardiogram and symptoms scoring in group A were superior to those in group B (P 0.05) . Whole blood high-shear viscosity (WBHSV) and whole blood low-shear viscosity (WBLSV) were decreased in the two groups (P 0.05). [Conclusion] Guanxin No. 1 Recipe has a better effect on relieving symptoms and improving EGG in CHD with AP, and this may be related to the decrease of blood lipid level and improvement of hemorrheology index.

OBJECTIVE:To tackle the problem of virtual-high drug price through reforming pricing mechanism of drugs. METHODS: To review the history of the pricing mechanism of medicines, analyzed the problems existed in the pricing mechanism and the reasons accountable for the high drug prices as well as the responsibilities of the related departments in the high drug prices, then a new pricing mechanism of medicines was put forward. RESULTS & CONCLUSIONS: The new pricing mechanism of drugs can bring down the drug prices to a large extent meanwhile increasing revenue for hospital even without the increase in financial appropriation. Hospitals can make profits in a way rather than from big examination of the patients, which can help reduce the medical costs paid by the common people.
