In the pathogenesis of major depressive disorder, chronic stress-related neuroinflammation hinders favorable prognosis and antidepressant response. Mitochondrial DNA may be an inflammatory trigger, after its release from stress-induced dysfunctional central nervous system mitochondria into peripheral circulation. This evidence supports the potential use of peripheral mitochondrial DNA as a neuroinflammatory biomarker for the diagnosis and treatment of major depressive disorder. Herein, we critically review the neuroinflammation theory in major depressive disorder, providing compelling evidence that mitochondrial DNA release acts as a critical biological substrate, and that it constitutes the neuroinflammatory disease pathway. After its release, mitochondrial DNA can be carried in the exosomes and transported to extracellular spaces in the central nervous system and peripheral circulation. Detectable exosomes render encaged mitochondrial DNA relatively stable. This mitochondrial DNA in peripheral circulation can thus be directly detected in clinical practice. These characteristics illustrate the potential for mitochondrial DNA to serve as an innovative clinical biomarker and molecular treatment target for major depressive disorder. This review also highlights the future potential value of clinical applications combining mitochondrial DNA with a panel of other biomarkers, to improve diagnostic precision in major depressive disorder.

应用SWAT 2012模拟泾河中上游流域的月径流量,并结合SWAT-CUP中的Parasol、SUFI-2、GLUE和PSO等4种参数优化算法对模型参数校准,并进行对比及适用性分析。结果表明:4种算法均能满足模拟精度要求,月径流模拟纳什系数(NS)和决定系数(R2)均在0.6以上,且GLUE和SUFI-2算法参数优化后模型模拟精度更高。GLUE算法优化后模型在校准期NS和R2分别为0.84和0.76,验证期为0.85和0.78;SUFI-2算法优化后模型在校准期NS和R2分别为0.81和0.67,验证期为0.86和0.70。如果条件允许,GLUE算法更适合较复杂的流域;SUFI-2算法可以缩短优化时间,但精度略低,因此更适合径流变化情况相对简单的流域。Parasol算法和PSO算法模拟历时长,精度较低,不适用于本流域参数优化,但PSO算法对于双峰径流模拟效果较好,较适用于有春汛出现的地区。
