Pathogenesis of depression and the potential for traditional Chinese medicine treatment.

Depression is a prevalent mental disorder that significantly diminishes quality of life and longevity, ranking as one of the primary causes of disability globally. Contemporary research has explored the potential pathogenesis of depression from various angles, encompassing genetics, neurotransmitter systems, neurotrophic factors, the hypothalamic-pituitary-adrenal axis, inflammation, and intestinal flora, among other contributing factors. In addition, conventional chemical medications are plagued by delayed onset of action, persistent adverse effects, and restricted therapeutic efficacy. In light of these limitations, the therapeutic approach of traditional Chinese medicine (TCM) has gained increasing recognition for its superior effectiveness. Numerous pharmacological and clinical studies have substantiated TCM's capacity to mitigate depressive symptoms through diverse mechanisms. This article attempts to summarize the mechanisms involved in the pathogenesis of depression and to describe the characteristics of herbal medicines (including compounded formulas and active ingredients) for the treatment of depression. It further evaluates their effectiveness by correlating with the multifaceted pathogenesis of depression, thereby furnishing a reference for future research endeavors.

Classical prescription Dachuanxiong Formula delays nitroglycerin-induced pain response in migraine mice through reducing endothelin-1 level and regulating fatty acid biosynthesis.

ETHNOPHARMACOLOGICAL RELEVANCE: Dachuanxiong Formula (DCXF) is a classical Chinese medicine prescription and is composed of dried rhizomes from Ligusticum striatum DC. (Chuanxiong Rhizoma) and Gastrodia elata Bl. (Gastrodiae Rhizoma) at the ratio of 4:1 (w/w). It has been used as Chinese medicine prescription for thousands of years. DCXF is used traditionally to treat many diseases, including migraine, atherosclerosis and ischemic stroke. AIM OF THE STUDY: This study aimed to investigate the effects of DCXF on pain response in migraine mice, and the underlying mechanisms using proteomics and bioinformatics analyses. MATERIALS AND METHODS: DCXF extract was prepared by mixing Chuanxiong Rhizoma and Gastrodiae Rhizoma at a mass ratio of 4:1 (w/w). After extraction, the extract was filtered prior to high performance liquid chromatography (HPLC) analysis. Nitroglycerin (NTG) was used to establish a mouse migraine model, and a behaviour study was conducted by hot plate test. In addition, proteomics and bioinformatics studies were conducted to investigate the mechanisms of DCXF-mediating anti-migraine treatment. RESULTS: Our results showed that there were significant differences in the latencies between NTG-treated and DCXF low dose- and high doses-treated groups at 30 min after NTG injection, this suggested that DCXF could ameliorate pain response in migraine mice. Besides, the plasma levels of endothelin-1 were also measured. NTG group significantly enhanced the endothelin-1 level compared to the control group. In contrast, DCXF low dose and high dose groups significantly reduced this level compared to NTG group. In addition, the underlying mechanisms were also investigated. Our results demonstrated that the anti-migraine treatment of DCXF was highly associated with fatty acid synthesis, suggesting that DCXF ameliorated pain response through reducing endothelin-1 level and regulating fatty acid synthesis. CONCLUSIONS: The present study revealed the anti-migraine effect of DCXF in migraine mice and provided insights into the mechanisms of DCXF-mediating anti-migraine treatment.

[Thoughts on post-marketing evaluation of classical Chinese patent medicines based on clinical value].

Classical Chinese patent medicines(CPMs) are a kind of modern preparation developed from the experience of compatibility and application about ancient prescriptions. Its rich history of human use and reliable clinical efficacy imply the unique theoretical essence and precious value of traditional Chinese medicine(TCM). With the development of evidence-based medicine and the improvement of medical policy, it is particularly urgent to evaluate the clinical values of post-marketing classical CPMs. In this paper, some problems on the clinical value evaluation of CPMs would be described, and it is considered that the simplified evaluation procedures can lead to the lack of evidence for evaluating clinical value of CPMs, causing the difficulty in evaluating the quality of CPM, lack of R&D motivation of enterprises, low content of science and technology, and poor international development. Based on this background, it points out that the clinical value evaluation is the core of the post-marketing evaluation of the classical CPMs, and the eva-luation should be based on the direction of literature research and the latest practice. We should adhere to the research mode of combination disease with syndrome, and select the appropriate type of trials, with clinical efficacy, health economic benefits and safety eva-luation as the main content of the studies, in order to refine the indications and standardize the clinical positioning. Clinical value eva-luation is the basis and main content of post-marketing comprehensive researches on classic and famous CPMs to clarify their clinical value, obtain the conditions for continued marketingand standardize their clinical application, so as to optimize the evidence and quality service of classic and famous CPMs and inherit the core value concept of Chinese medicine.

Epidemiology is ecosystem science.

This paper primarily argues that Epidemiology is Ecosystem Science. It will not only explore this notion in detail but will also relate it to the argument that Classical Chinese Medicine was/is Ecosystem Science. Ecosystem Science (as instantiated by Epidemiology) and Ecosystem Science (as instantiated by Classical Chinese Medicine) share these characteristics: (a) they do not subscribe to the monogenic conception of disease; (b) they involve multi variables; (c) the model of causality presupposed is multi-factorial as well as non-linear.

[Chinese medicine and constructivism-a new way in psychotherapy]. / Chinesische Medizin und Konstruktivismus ­ ein neuer Weg in der Psychotherapie.

BACKGROUND: The background of this study is twofold: basic methodological differences between Western Biomedicine and Classical Chinese Medicine (CCM) and obvious parallels between the methodology of psychotherapy and CCM. OBJECTIVES: Drawing on available investigations on the methodology of CCM, the analysis of structural parallels between CCM and Western psychotherapy tries to enrich the methodological self-conception of psychotherapy in order to provide impulses for the new approaches to psychotherapeutic practice. METHODS: The reciprocal interpretation of CCM about the patient's state draws on a language of metaphors. These metaphors "mediate" between the various positions of the universal interdependency and the human being, who is able to understand the language. The constructive realistic methodology in general and the epistemological method of "alienation" in particular, provide an instrument for the decodification of these metaphors. RESULTS: In the context of CCM, the process dynamics of mental healing are based on hermeneutical principals. Every operation carried out by the CCM therapist is not organ medical in nature but a purely semantic form. These semantic operations aim to provide a meaningful integration of problematical behavior (in terms of meaning) into metaphorically logical structures in order to stimulate a coherent self-understanding of the suffering individual, which is associated with healing effects. In this context, it is crucial for CCM that there is no conceptual division between body and soul with respect to the therapy. This enables a completely different comprehensive treatment of mental problems than biomedicine is able to offer, due to its methodological presuppositions.
