RESUMEN
@#【Objective】 To study the composition and function of tongue coating (TC) and gastrointestinal tract (GIT) microbiota in participants with yellow-greasy tongue coating (YGTC), and to explore the representative metabolite markers and pathways in this group. 【Methods】 Subjects with YGTC or thin-white tongue coating (TWTC) were recruited from December 1, 2021 to October 30, 2022, and the TC and fecal samples were collected. Samples were subjected to both whole-genome shotgun (WGS), and 16S rRNA gene sequencing. The α-diversity analysis, principal component analysis (PCA), and Spearman correlation analysis were performed for two groups. Ultra-performance liquid chromatography combined with tandem mass spectrometry (UPLC–MS/MS) analysis was used to analyze metabolomics and enrichment of metabolic pathways. 【Results】 The results revealed 20 YGTC participates and 19 TWTC participates. At the genus level, the dominant bacterial species of TC flora and intestinal flora in the two groups were roughly the same, but the relative kurtosis difference was marked, and the abundance of potentially pathogenic bacteria in TC and fecal samples of YGTC subjects was higher. There were 9 down-regulated microorganisms in the TC samples, 26 down-regulated microorganisms, and 6 up-regulated microorganisms in YGTC subjects. The α-diversity analysis indicated that the Chao and abundance-based coverage estimator (ACE) indices of TC bacteria in the YGTC subjects showed a decreasing trend, but the difference was not statistically significant (P > 0.05). The α-diversity of fecal samples and the Chao and ACE indices decreased significantly (P < 0.05). PCA showed that the microflora structure of TC and fecal samples were significantly different between the two groups. Spearman correlation analysis showed that there was no correlation between TC and fecal microorganisms at phyla and genus levels in the same subjects (P > 0.05). The metabolomics results demonstrated that fumarate reductase, V/A ATPase, and phosphatidylethanolamine were increased, and glycerate-3p, UDP-glucose, and quinone oxidoreductase metabolites were decreased in YGTC TC samples. Inosine monophosphate (IMP), uridine monophosphate (UMP), and gamma-aminobutyric acid(GABA) were increased in YGTC fecal samples, while the contents of ribo-5P, histidine, biotin,and cobalamin were decreased. Metabolic pathway analysis indicated that the abundance of the TC and fecal samples of the YGTC subjects was relatively low in various metabolic pathways, including amino acid metabolism, carbohydrate metabolism, nitrogen metabolism, and energy metabolism. 【Conclusion】 Structural and functional changes in TC and GIT microbiota or metabolite markers could be potential biological bases of YGTC formation.
RESUMEN
Asymptomatic spleen-stomach diseases refer to diseases without related symptoms and signs of abdo-minal pain， bloating， diarrhea an others in patients， but showing lesions or pathological changes discovered by modern medical techniques such as endoscopy， CT， MRI. The four examination techniques of traditional Chinese medicine （TCM） are based on symptoms and signs of patients， which are the advantage of TCM but also have certain limitations. In the context of the increasingly modernized diagnosis and treatment in TCM， it is proposed to expand the application of the four examination techniques from three aspects including microcosmic syndrome differentiation， data sharing， and artificial intelligence in asymptomatic spleen-stomach diseases， in order to achieve the goals of dynamically observing the disease process， collecting disease data in multiple dimensions， and intelligently processing disease data. This will strengthen the modern requirements of early diagnosis and treatment in TCM， and highlight the advantages of TCM in “treating disease before it arises and treating the symptoms beforehand”.
RESUMEN
Since the theory of microcosmic syndrome differentiation was put forward in 1986, Chinese medicine academia has been unremittingly exploring this theory. Efforts were made to explain the syndrome in Chi-nese medicine with objective index of modern medicine, so that different syndromes of the same disease can be rec-ognized on the quantitative view and then apply syndrome differentiation with objective index. This paper compre-hensively analyzed and got the primary causes why microcosmic syndrome differentiation was difficult to apply. It in-cluded no-identical criterion, research design such as the choice of syndrome, reference syndrome, objective index and microcosmic level. Additionally, too many virtual syndromes resulting from applying syndrome differentiation on western medicine diseases existed widely. Consequently, it is extremely urgent that solve these problems and regulate the research thought.
RESUMEN
Objective To discuss the microcosmic elements and syndromes distribution of H pylori-related gastritis. [Method] Choose 100 cases, under gastroscope report, make statistics of frequency of disease nature elements and location elements, combine the nature and location for common syndromes. [Result] The H pylori-related gastritis has main disease location elements in stomach, esp. the sinuses ventriculi;the disease nature elements mainly concern hot, wet, sputum stasis, deficiency and blood stasis; the common syndromes: hot stomach, sputum and stasis blocking stomach, wet-hot accumulated in stomach, deficient stomach, wet stranding stomach and stasis blocking gastric col aterals. [Conclusion] Over the inconsistent syndromes in clinical H pylori-related gastritis, the microcosmic elements differentiation can further standardize syndromes and guide the treatment.
RESUMEN
One of the characteristics and advantages of Chinese medicine is holism,which emphasizes harmony of human and nature.It compares the physiological and pathological change of human body with the natural normal or unmoral change by using thinking of analogy by classification,inferring the internal essence according to external synptoms and signs.And it intends to reveal body black-box,and holds physiological and pathological change from macroscopic level,but there are some fuzziness and ambiguity.With the development of morden science on the microscopic fields,some breakthroughs and theoretical systems are established.As the same,Chinese medicine holism must be micro-adjusted and establish its own micro-holism theory,which will be benefit for itself.
RESUMEN
The paper introduces microcosmic control model for medical morals construction.The function of the model includes explanation,operation and evaluation.The author holds that the key to the morals construction is scientific management,and the decision maker should have the social responsibility and the love-patient consciousness.
RESUMEN
Object To study microcosmic mechanism about microwave-assisted extraction (MAE) to Radix Puerariae (RP) and Radix Caulis Acanthopanacis Senticosi (RCAS). Methods By transmission electron microscope, the structure changes about tonoplast in RP and RCAS were observed. Results The effect on tonoplast was differently made by MAE and conventional reflux extracting method. Conclusion The effective ingredients could be dissolved more easily with MAE than conventional reflux extracting method.
