The results indicated that in the warming-reinforcing group, TC decreased markedly and HDL increased obviously with significant difference as compared with the twirling-reinforcing group:TC and LDL also decreased, but no significant differencte as compared with the twirling-reinforcing group. Warming-reinforcing method can decrease lipids more effectively than twirling-reinforcing method.展开更多

As the incidences of hypertension and coronary heart disease were also significantly higher in psoriatics than in controls, the authors proposed that some integrated relationship would exist.展开更多
