应用高压液相色谱（ＨＰＬＣ）对６７例精神分裂症脑脊液中多巴胺（ＤＡ）、去甲肾上腺素（ＮＥ）进行测试，以ＮＥ／ＤＡ为相互作用指标，并以其中位数将受试者分为高ＮＥ／ＤＡ比值组（１５例）和低ＮＥ／ＤＡ比值组（５２例）。结果发现，低比值组的ＢＰＲＳ及其阳性症状显著高于高比值组，且ＮＥ／ＤＡ与之呈显著性负相关。同时还发现，高、低比值组的阴、阳性亚型构成有显著性差异，低比值组年龄明显低于高比值组，但未发现两组在家族史、性别之差异。本研究结合ＮＥ／ＤＡ意义进行了讨论
The dopamine (DA) and norepinephrine (NE) in 67 schizophrenic cerebrospinal fluid samples were tested by high pressure liquid chromatography (HPLC) with NE / DA as the interaction index and the median For the high NE / DA ratio group (15 cases) and low NE / DA ratio group (52 cases). The results showed that BPRS in low ratio group and its positive symptoms were significantly higher than those in high ratio group, and NE / DA had a significant negative correlation. At the same time, it was also found that there was a significant difference in the composition of the yin and yang subtypes in the high and low ratio groups, the age in the low ratio group was significantly lower than that in the high ratio group, but the differences in family history and gender were not found between the two groups. This study is based on the NE / DA significance
