RESUMO
Decoction pieces are the main body of traditional Chinese medicine (TCM) clinical medication. With the modernization of TCM medication, TCM formula granules have gradually developed and begun to take shape. Although there are processing forms of TCM injection and oral liquid, they only account for a small part of TCM market and are mainly taken orally. However, when oral administration of lipid soluble ingredients is conducted, the dissolution is limited and the absorption is relatively small. In addition, it has side effects of stimulating gastrointestinal tract, resulting in low tolerance of patients. Although there are topical preparations made by water extraction and alcohol extraction, most of them are crude preparations with random dosage, which results in the waste of lipid soluble components to a certain extent. Most of the lipid soluble components of TCM have good biological activities, such as schisandrin b, tanshinone, methyl chlorogenic acid, etc., but there is no suitable medicinal form. To make the best use of "medicine", it is necessary to systematically study the lipid soluble components of TCM. On the basis of fairly mature extraction, separation and collection processes, a medicinal form with definite pharmacological effect and beneficial to its absorption is developed based on lipid soluble components. TCM essential oil has anti-aging, anti-dementia, anti-oxidation and other activities, which has been widely used in clinical, cosmeceuticals, health products and other fields. However, the effect of single essential oil is limited. Compatibility can not only enhance the efficacy and reduce toxicity, but also expand the application range of essential oil. Therefore, formula essential oil can be used as a new form of TCM, and mainly for external use, supplemented by internal use, to make up for the disadvantages of crude preparations and random dosing for external use of TCM, as well as the disadvantages of orally absorbed less and stimulated gastrointestinal tract, to meet the needs of clinical medication, faster, more accurate, better and stronger play the effect of lipid soluble components.
RESUMO
Objective: To analyze the medication rules of traditional Chinese medicine (TCM) in treating type 2 diabetes mellitus (T2DM),and explore the mechanism of action.Method: The articlesabout TCM treatment for T2DM in CNKI and Wanfang Med Online were retrieved.The data was entered into Excel 2013 to set up a database,and the factor analysis,association rules and cluster analysis were used to analyze core medication combinations by SPSS Statistics 19.0 and SPSS Modeler 14.1.kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis was performed using BATMAN-TCM to reveal the mechanism of action.Result: A total of 92 prescriptions were included,the high frequency medicines were Astragali Radix.The major properties of TCM were cold and plain.The major flavors of TCM were sweet and bitter.The major meridian tropism of TCM was livermeridian.These high frequency medicines were deficiency-nourishing herbs,and blood circulation-invigorating and stasis-eliminating herbs.Totally 6 core medication combinations were mined through association rules.Seven common factors were extracted from factor analysis.Clustering analysis was used to get 6 kinds of herbs.KEGG pathway analysis revealed 24 biological pathways and 6 diseases relating to T2DM.Conclusion: The most commonly used Astragali Radix for treating T2DM.In clinical,it can be combined with Poria,Salviae Miltiorrhizae Radix et Rhizoma and Rehmanniae Radix for treating T2DM.At the same time,it can be combined with such herbs as deficiency-nourishing herbs,and blood circulation-invigorating and stasis-eliminating herbs.The mechanism of action of high-frequency herbs may be related to the targets of exophosphatase/phosphodiesterase (PDEs),adenosine A1 receptor gene 1(ADORA1),adenosine A2A receptor gene (ADORA2A),neuropetide second receptor (NPY2R),and endothelial carbon monoxide synthase (NOS3) by interfering with PI3K/Akt,starch and sucrose metabolism signaling pathways.
RESUMO
Polycystic ovary syndrome (PCOS) is a common gynecological reproductive endocrine and metabolic disorder disease. The clinical manifestations of PCOS are diversified, with and no ovulation, insulin resistance, hyperinsulinemia and polycystic ovaries as the main pathological and physiological changes, which can lead to non-ovulation infertility and ovulatory dysfunction infertility, cause complications, such as amenorrhea, diabetes, lipid metabolism and glucose metabolism disorder, and endanger the long-term health of the body. Traditional Chinese medicine (TCM) does not have the name of this disease, and classifies PCOS to the category of "amenorrhea", "infertility" and "abdominal mass kidney" according to its clinical manifestations. Compared with western medicine, TCM has a unique view in treating the disease, and believes that the disorders of liver, kidney and spleen functions jointly affect the occurrence and development of the disease. According to the literature review, kidney-deficiency syndrome is the main syndrome type of this disease, the kidney-tonifying method has achieved a good effect in clinic. Besides, the drug use is flexible and diversified, and both primary and secondary symptoms are taken into consideration. However, in the clinical application process, the application of kidney-tonifying method in PCOS has been affected by the thinking mode of "kidney-tonifying medicine for male diseases" to some extent. In view of this, the therapeutic effect of kidney-tonifying drugs in the treatment of PCOS is preliminarily demonstrated from several aspects of the relationship between kidney deficiency and reproduction, pathogenesis of PCOS, clinical research and experimental research of PCOS, in the expectation of providing theoretical and practical supports for kidney-tonifying therapy for PCOS and other gynecological diseases.
RESUMO
<p><b>OBJECTIVE</b>To explore cell death and apoptosis in rat hippocampal neurons at different time points after ischemia, hypoxia and reperfusion injury and to elucidate time window characteristics in ischemia neuronal injury.</p><p><b>METHODS</b>Hippocampal neurons were obtained from rat embryo and were cultured in vitro. The ischemia and reperfusion of cultured rat hippocampal neurons were simulated by oxygen-glucose deprivation (OGD) and recovery. OGD at different time points (0.25 h to 3.0 h) and then the same recovery (24 h) were prepared. Annexin V-PI staining and flow cytometry examined neuron death and apoptosis at different time after injury.</p><p><b>RESULTS</b>After OGD and recovery, both necrosis and apoptosis were observed. At different times after OGD, there were statistically significant differences in neuron necrosis rate (P < 0.05), but not in apoptosis rate (P > 0.05). At recovery, survival rate of hippocampal neurons further decreased while apoptosis rate increased. Furthermore, apoptosis rates of different time differed greatly (P < 0.05). Apoptosis rate gradually increased with significant difference among those of different time points (P < 0.05). However, 2 h after ischemia, apoptosis rate decreased markedly.</p><p><b>CONCLUSIONS</b>Apoptosis is an important pathway of delayed neuron death. The therapeutic time window should be within 2 h after cerebral ischemia and hypoxia.</p>
