TREATMENT: Except for anti-coagulation therapy, aminophyllini was an inexpensive medicine to treat PTE, it could largly lower Hb and Hct by reducing the secretion of EPO. Its defect was rechallenge of PTE with the drug stopped, and repeated administration was still effective. The side effect was exciting symptoms. Enalapril was a storng hypotensor which could also greatly lower Hb and Hct with the decline in PRA/AT-Ⅱ, and then decreasing serum EPO. In this therapy blood pressure shonld be monitored to prevent from postural hypotention. At last, it showed that diltiazemi had no obvious effect on PTE.

四、治疗研究：分别以氨茶碱、恬尔心、Enalapril来治疗PTE病人，发现氨茶碱能明显降低PTE病人的Hb及Hct，且该作用与EPO降低有关，其缺点是停用后可引起复发，但继续服用仍有效，该药的副作用主要为头痛、失眠等兴奋症状；Enalapril不但能显著降低Hb及Hct，还可治疗难治性高血压，适用于伴有高血压的PTE病人；恬尔心对PTE的治疗作用不大。
