目的 探讨不同剂量丙戊酸钠对双相情感障碍（BPD）患者血清促甲状腺激素（TSH）、泌乳素（PRL）及多巴胺（DA）水平的影响。 方法 选择2020年5月至2022年5月接受治疗的90例BPD患者为研究对象，随机数字表法分为A、B、C三组，均为30例，A、B、C三组每天分别口服10、15、20 mg/kg丙戊酸钠。比较3组临床疗效、治疗前后各项精神疾病评分、血药浓度相关指标、治疗前后血清水平、肝功能相关指标以及不良反应发生率。 结果 3组治疗后总有效率差异无统计学意义（P > 0.05）；治疗后3组各项评分相较于治疗前显著性改善（P < 0.05）；3组达稳态血药浓度谷值时间比较差异有统计学意义（P < 0.05）；治疗后3组TSH、PRL及DA水平相较于治疗前差异无统计学意义（P > 0.05）；治疗后3组ALT、AST水平相较于治疗前均有所上升（P < 0.05），治疗后3组ALT、AST水平比较差异有统计学意义（P < 0.05）；3组不良反应发生率比较差异有统计学意义（P < 0.05）。 结论 丙戊酸钠可有效治疗BPD患者，缓解狂躁或抑郁程度，对TSH、PRL及DA水平无明显影响，其中小剂量丙戊酸钠在保证治疗效果的同时对肝功能的影响较小，且不良反应更少，安全性高，值得临床推广。

Objective To explore the effects of different doses of valproate on serum thyroxine （TSH）， prolactin（PRL）and dopamine （DA） in patients with bipolar disorder （BPD） level of influence. Methods A total of 90 patients with BPD who received treatment in hospital from May 2020 to May 2022 were selected as the study objects. They were randomly divided into groups A， B and C， with 30 cases in all. Groups A， B and C were orally administered 10 mg/kg， 15 mg/kg and 20 mg/kg sodium valproate every day， respectively. The clinical efficacy， scores of mental diseases before and after treatment， indexes related to blood drug concentration， serum levels before and after treatment， indexes related to liver function and incidence of adverse reactions were compared among the three groups. Results There was no significant difference in the total effective rate among the three groups after treatment （P > 0.05）. After treatment， the scores of the three groups were significantly improved compared with before treatment （P < 0.05）. There was significant difference in the time to reach the stable state serum concentration （P < 0.05）. There were no significant differences in TSH， PRL and DA levels among the three groups after treatment compared with before treatment （P > 0.05）. ALT and AST levels in the three groups after treatment were increased compared with those before treatment （P < 0.05）， and there were statistically significant differences in ALT and AST levels among the three groups after treatment （P < 0.05）. There was significant difference in the incidence of adverse reactions among the three groups （P < 0.05）. Conclusion Sodium valproate can effectively treat BPD patients and relieve the degree of mania or depression， but has no significant effect on the level of TSH， PRL and DA. Among them， small dose of sodium valproate can guarantee the therapeutic effect and have less impact on liver function， and less adverse reactions， high safety， worthy of clinical promotion.
