To evaluate the therapeutic effects of Rong Shuan Jiao Nang (RSJN) on treatment of acute mountain sickness (AMS) and high altitude myocardial ischemic syndrome in workers in Yushu,three groups were studied: group A (60 patients with AMS,given RSJN),group B (15 patients with altitude myocardial ischemic syndrome, given RSJN),and group C (control,without drugs). All studied subjects were lowland workers who were first time entry to Yushu for work at an altitude of 4 250 m. During the course of treatment,a routing physical examination was performed,AMS Lake Louise Scores were estimated,arterial oxygen saturation (SaO2),electrocardiography and hemoglobin concentration were measured before and after using RSJN for 10 days. In group A,the effective rate was 68 %,symptomatic improvement in 54 cases (90 %) within 5 days. In group B,the effective rate was 93 %,episodes of angina pectoris stopped in 12 patients within 3 ~ 7 days,one lasted 8 days. After treatment, the level of SaO2 increased 15.5 %,21.8 % and 5.6 % in group A,group B and group C,respectively. RSJN taken at the start of the arrival at Yushu can decrease AMS scores and facilitate cure. If taken after the illness has begun,RSJN may help lessen symptoms,especially effectively improved angina pectoris of the high altitude myocardial ischemic syndrome. Symptoms usually subside after 3 ~ 8 days. RSJN should be continually used for at least 7 days after ascent. 相似文献
