Pi (Spleen)-Deficiency Syndrome in Tumor Microenvironment Is the Pivotal Pathogenesis of Colorectal Cancer Immune Escape

Cancer immunoediting consists of three sequential phases: elimination, equilibrium, and escape. For colorectal adenoma-carcinoma sequence, the adenoma dysplastic progression may represent an equilibrium phase and the cancer stage as escape phase. Immune system eliminates transformed enterocytes by destroying them at first, sculpts them at the same time and selects the variants subsequently that are no longer recognized and insensitive to immune effectors, and finally induces immunosuppressive state within the tumor microenvironment that facilitates immune escape and tumor outgrowth. Immunosuppression and inflammation are the two crucial features of Pi(Spleen)-deficiency. Classic quotations, immune evidence and clinical observations suggest that Spleen(but not other organs) deficiency is the key pathogenesis of colorectal cancer(CRC) microenvironment. Weakness of old age, immunosuppressive cytokines from chronic inflammation, tumor-derived immunosuppressive factors and surrendered immune cells—regulatory T cells, myeloid-derived suppressor cells and tumor associated macrophages(TAMs) constitutes CRC microenvironment of Pi-deficiency. Furthermore, excess in superficiality, such as phlegm stagnation, blood stasis and toxin accumulation are induced by chronic inflammation on the basis of asthenia in origin, an immunosuppressive state. Great masters of Chinese medicine emphasize that strengthen Pi is the chief therapeutic principle for CRC which receives good therapeutic effects. So, Pi-deficiency based syndrome is the pivotal pathogenesis of tumor microenvironment. The immunosuppressive microenvironment facilitates immune escape which play an important role in the transition from adenoma to adenocarcinoma. There are some signs that strengthen Pi based treatment has potential capacity to ameliorate tumor environment. It might be a novel starting point to explore the mechanism of strengthen Pi based therapy in the prevention and treatment of CRC through regulation of tumor environment and immunoediting.

Chinese integrative medicine: Translation toward person-centered and balanced medicine

<正>Chinese integrative medicine(CIM) focuses on the integration of conventional medicine (biomedicine) with Chinese medicine(CM).Although the CIM field has witnessed several advancements,the definition and classification of CIM is not quite clear,given that an independent theory system has not yet been established in this field.Therefore,future research and studies should focus on the following objectives:(1) emphasizing CM features,(2) improving CIM positioning,and(3) establishing CIM standards.These concerted efforts will help CIM be at par with international standards and criteria.With the development of CIM,the world will embrace a new medical system providing person-centered treatment with a balanced medicine approach.

Proteomic Analysis of Chronic Restraint Stress-Induced Gan (肝)-Stagnancy Syndrome in Rats

Objective: To analyze the proteomic characteristics of Gan (肝))--ssttaaggnnaannccyy syndrome ((GGSSSS)) by seeking the differential protein in blood and tissues of GSS model rats.Methods: GSS model rats were established by chronic restraint stress,keeping rats in restrain chamber for 6 h every day for 21 successive days.Their blood and liver samples were collected at the end of experiment for differential protein detection with methods of isoelectrofocusing and polyacrylamide SDS-PAGE,silver staining,and scanning.The gel images were analyzed with Imagemaster 2D Elite software,and the excavated differential protein spots were identified with matrix assistant laser resolving TOF mass spectrometry,Western blot,ELISA,and RT-PCR,respectively.Results: A method for isolating the protein in blood serum and tissues by two-dimensional gel electrophoresis was established and optimized.Six serum proteins and three liver proteins that differentially expressed were identified.The down-regulated differential proteins in serum of GSS model rats were serum albumin precursor,beta 1 globin,antibody against muscle acetylcholine receptor,Ig lambda-2 C region,and transthyretin (TTR),and those in liver tissue were aryl sulfotransferase,enoyl-CoA hydratase,and TTR.TTR down-regulation was found in both serum and liver.Preliminary biological information analysis showed that these differential proteins involved in immune,neuroendocrine,nutrition,and substance metabolism.Conclusion: Proteomic analysis of differential proteins showed that TTR,aryl sulfotransferase,and enoyl-CoA hydratase expressions are downregulated in the GSS model rats,suggesting that the susceptibility of cancer could be enhanced by chronic stress.
