- Abstract：Depression is a kind of emotional and mental disorder， which is related to many pathogenic factors， such as abnormal metabolism of monoamine neurotransmitters， immune inflammatory reaction， neuroendocrine disorder and so on. it has the characteristics of high disability rate and high recurrence rate， which is seriously harmful to human health. It brings huge economic burden to patients and their families. At present， the commonly used antidepressants in clinic are monoamine oxidase inhibitors， tricyclic antidepressants and selective 5-hydroxytryptamine reuptake inhibitors. Long-term use causes adverse reactions such as cardiovascular， urinary and digestive dysfunction. The multi-target， multi-pathway and multi-mechanism of traditional Chinese medicine has played a great role in the treatment and rehabilitation of depression. At the same time， traditional Chinese medicine has gradually become a hot spot in the research and development of antidepressants because of its small side effects and good drug compliance. Especially the ZHANG Zhong-jing's classical formulae with precise medication and rigorous prescription has unique advantages in the treatment of depression. For thousands of years， it has been used clinically by countless doctors in the treatment of various types of depression， with definite curative effects and few side effects. In recent years， clinical research， experimental research， and pharmacological research around ZHANG Zhong-jing's classical formulae for depression have been continuously expanded and deepened. This article reveals the rules of medication of the treatment of depression with ZHANG Zhong-jing's classical formulae from three aspects of Bupleurum class prescription， Gardenia class prescription， and other prescriptions， which is reflected in the study on the composition of prescription， the etiology， and pathogenesis and the symptoms of the treatment. Integrating and classifying ZHANG Zhong-jing's classical formulae's experience in the treatment of depression， mainly expounded from two aspects， clinical research and pharmacological research， summarizing the research perspective and progress of Zhongjing prescription medicine in the treatment of depression in recent years， to excavate， inherit and develop ZHANG Zhong-jing's classical formulae， and provide experience and reference for the treatment of depression from multiple angles and ideas.Keywords：ZHANG Zhong-jing's classical formulae;depression;research progress;Bupleuri Radix class prescription;Gardeniae Fructus class prescription356|215|9

- Abstract：Depression is a common emotional disease，causing a heavy burden of disease on patients' families and society.Its pathogenesis is not yet fully understood，andmay be related to inflammation，neurotransmitters，neurotrophicfactors，hippocampal neuronal synaptic plasticity，oxidative stress，etc.Clinical application of Western medicine to treat depression has serious side effects，poor patient compliance，the effective rate is not high，rebound after withdrawal，etc.Traditional Chinese medicine treatment of depression has the characteristics of low side effects and high patient compliance. Depression belongs to the category of depression syndromein traditional Chinese medicine.Traditional Chinese medicine believes that the main symptoms of depression include depressed liver Qi，stagnated Qi transforming into fire，deficiency in heart and spleen，deficiency in heart and lung，stagnation of phlegm and Qi，deficiency of liver and kidney，etc. Banxia Houpu Tang is a classic recipe contained in"Synopsis of the Golden Chamber" by Zhang Zhongjing in the Han Dynasty， it has the effect of treating depression syndrome of stagnation of phlegm and Qi.By searching the literatures of Banxia Houpu Tang in the treatment of depression in Chinese knowledge network database （CNKI），Chinese biomedical literature database （CBM）， Wanfang Data， Pubmed， Embase， Web of Science and other databases，we found that both clinical application and experimental research suggest that Banxia Houpu Tang has a significant antidepressant effect. Clinical studies have shown that Banxia Houpu Tang can improve the scores of anxiety scales and depression scales of patients with depression. The antidepressant effect is significant， and the advantages are prominent. Experimental research shows that the antidepressant effect of Banxia Houpu Tang and its effective components may be related to the factors such as intervention of inflammatory response， influence of neurotransmitters， regulation of neurotrophic factors， improvement of synaptic plasticity of hippocampal neurons and reduce oxidative stress，etc. Therefore，this paper reviews several types of depression in the clinical treatment of Banxia Houpu Tang and the related experimental studies of Banxia Houpu Tang.Keywords：Banxia Houpu Tang;depression;clinicalapplication;experimentalstudy;review281|183|7<HTML><H-PDF><L-PDF>Updated：2020-12-10
