中文摘要:
      目的：探讨心境稳定剂是否通过影响肠道菌群改善双相情感障碍（BD）躁狂发作患者症状。方法：利 用杨氏躁狂量表（YMRS）评估42例BD患者治疗前、后的临床症状，并采集粪便样本提取基因组DNA。经 PCR扩增、文库构建和质检后，利用16S rDNA高通量测序和Uparse软件聚类筛选获得OTUs；利用QIIME 软件计算肠道菌群α多样性的指数（Chao1指数、Observed species指数、Shannon指数和Simpson指数）；使用 基于OTUs的Bray-Curtis距离进行PCoA分析，计算肠道菌群β多样性；利用LEfSe软件应用线性判别分析 方法（LDA）进行差异物种筛选；ELISA检测BD患者治疗前、后血清IL-1β和TNF-α含量。结果：治疗前BD 组的Chao1指数、Observed species指数、Shannon指数和Simpson指数低于HC组（P＜0.05），治疗后BD组 的Chao1指数和Observed species指数高于治疗前（P＜0.05）；治疗前BD组的厚壁菌门及其下的梭菌纲、梭 菌目、瘤胃球菌科、韦荣菌科、变形菌门和放线菌门丰度高于HC组，而治疗后BD组的厚壁菌门及其下毛螺 菌科、醋酸菌科和拟杆菌目的丰度高于治疗前BD组（P＜0.05）；治疗前BD组的毛螺菌科相对丰度低于HC 组和治疗后BD组（P＜0.05），而治疗后BD组毛螺菌科相对丰度与HC组差异无统计学意义（P＞0.05）；肠 道毛螺菌科相对丰度分别与YMRS总分、IL-1β和TNF-α含量呈负相关（P＜0.05）。结论：心境稳定剂可通 过影响肠道菌群改善BD患者的症状。
英文摘要:
      To study whether mood stabilizers improve symptoms in bipolar disorder (BD) patients by affecting gut microbiota. Methods: The Young Manic Rating Scale (YMRS) was used to evaluate the clinical symptoms of 42 patients with BD before and after treatment, and patients’stool samples were collected for DNA extraction. After PCR amplification, library construction, and quality control, OTUs were obtained by 16S rDNA high-throughput sequencing and Uparse software clustering screening. QIIME software was used to calculate the index of α diversity, including the Chao1 index, observed species index, Shannon index, and Simpson index. PCoA analysis using Bray-Curtis distances based on OTUs was performed to calculate β diversity. LEfSe software was used to screen for different species by linear discriminant analysis (LDA). Serum IL-1 β and TNF-α levels were detected by ELISA before and after treatment in BD patients. Results: The indexes of Chao1, observed species, Shannon and Simpson in the BD group were lower than those in the healthy control (HC) group (P<0.05). The indexes of Chao1 and observed species in the BD group were higher after treatment than before (P<0.05). The abundance of Firmicutes and their subordinate Clostridiales, Clostridia, Ruminococcaceae, and Veillonellaceae, Proteobacteria, and Actinobacteria in the BD group before treatment was higher than that in the HC group, while the abundance of Firmicutes and its subordinate Lachnospiraceae, Acetobacteraceae, and Bacteroidales in the BD group was higher after treatment than before (P<0.05). The relative abundance of Lachnospiraceae in the BD group before treatment was lower than that of the HC group and the BD group after treatment (P<0.05), but there was no significant difference in the relative abundance of Lachnospiraceae between the BD group after treatment and the HC group (P>0.05). The relative abundance of Lachnospiraceae was negatively correlated with YMRS score and with levels of IL-1β and TNF-α (P<0.05). Conclusion: Mood stabilizers can relieve symptoms of bipolar disorder by way of gut microbiota changes.
