ABSTRACT
Objective:To discuss the effect of Sishenwan on phosphatidylinositol-3 kinase/protein kinase B/mammalian target of rapamycin（PI3K/Akt/mTOR） signaling pathway related genes and proteins in colon tissue and interleukin-1<italic>β</italic>（IL-1<italic>β</italic>） and interleukin-10（IL-10） expression levels in serum of ulcerative colitis （UC） model rats with spleen kidney Yang deficiency. Method:The 120 SPF Wistar rats were randomly divided into normal group and model group after 7 days of adaptive feeding in SPF laboratory. The model group were given dinitrobenzene sulfonate （DNBS）/ethanol solution enema+hydrocortisone subcutaneously injection+senna leaf gavage to establish UC model of spleen kidney yang deficiency. The rats who successfully established the model were randomly divided into five groups：model group， mesalazine （0.36 g·kg<sup>-1</sup>） group， and Sishenwan high， medium and low dose （3.2，1.6，0.8 g·kg<sup>-1</sup>） groups， the volume of which was 10 mL·kg<sup>-1</sup>. The model group and the blank group were given distilled water of the same volume. Once a day for 21 days. Observe the general conditions of the rats daily， and record the weight， fecal traits and occult blood of the mice for disease activity index （DAI） scoring.Take the rat colon tissue to observe the gross morphology and colon injury， and score the colon mucosal injury index （CMDI）. Hematoxylin-eosin （HE） staining was used to observe pathological changes. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR）was used to detect the expression level of PI3K， Akt， mTOR mRNA in colon tissue. The levels of IL-1<italic>β</italic> and IL-10 in serum were detected by enzyme-linked immunosorbent assay （ELISA）. Western blot was used to detect the expression level of PI3K， phosphorylation （p）-PI3K， Akt， p-Akt， mTOR， p-mTOR protein in colon tissue. Result:Compared with blank group， the general survival status of the rats in model group was relatively poor， the DAI score and the CMDI index were significantly increased （<italic>P<</italic>0.01）. The intestinal mucosa partially disappears， the glands disappear， and a large number of inflammatory cells infiltrate and gather in the mucosal layer and the base layer in the pathological sections of the model group. The expression levels of PI3K， Akt， and mTOR mRNA were significantly increased （<italic>P</italic><0.01）. The IL-1<italic>β</italic> content was significantly increased and the IL-10 content was significantly decreased （<italic>P</italic><0.01）. The expression levels of p-PI3K，p-Akt and p-mTOR protein were significantly increased （<italic>P</italic><0.01）. Compared with the model group， the DAI scores of Sishenwan high and medium dose groups and mesalazine group decreased （<italic>P</italic><0.05）. The CMDI index of mesalazine group and the high， middle and low dose groups of Sishenwan was significantly reduced （<italic>P</italic><0.01）. Pathological sections of rats showed that the inflammatory cells in the drug group decreased， and the mucosal layer structure returned to normal to varying degrees. The mesalazine group and the Sishenwan medium-dose group had the best effects， and the mucosal structure was close to the blank control group. The expression levels of PI3K， Akt， mTOR mRNA in the high and medium dose groups of Sishenwan， mesalazine group and Akt mRNA in low dose group of Sishenwan were significantly reduced （<italic>P</italic><0.05，<italic>P</italic><0.01）. The expression levels of PI3K and mTOR mRNA in low-dose group of Sishenwan decreased， but the difference was not statistically significant. The IL-1<italic>β</italic> content was significantly reduced and the IL-10 content was significantly increased in high， medium dose groups of Sishenwan and mesalazine groups （<italic>P</italic><0.05，<italic>P</italic><0.01）. The level of IL-1<italic>β</italic> decreased and the level of IL-10 increased in the low-dose group of Sishenwan， but the difference was not statistically significant. The expression levels of p-PI3K， p-Akt and p-mTOR protein in the high， medium， and low dose groups of Sishenwan and mesalazine group decreased to varying degrees， and the differences were statistically significant（<italic>P</italic><0.05，<italic>P</italic><0.01）. Conclusion:Sishenwan has the effect of improving the general condition and intestinal mucosal damage of ulcerative colitis model rats with spleen and kidney Yang deficiency. The mechanism may be related to the inhibition of PI3K/Akt/mTOR signaling pathway.
ABSTRACT
The academic origin of homogeny of spleen and pancreas is explained from the aspect of Chinese medicine.The authors think spleen faihng to spread essence is the basic pathogenesis to diabetes mellitus.Spleen function of spreading essence is impaired.Thus essence of water and grain could not be spread in the whole body but amass sugar-turbidity,which manifests high blood sugar.Differentiating diabetes mellitus from the viewpoint of spleen,invigorating spleen and benefiting Qi could help spleen to ascend clear.Invigorating spleen-yin and clearing endogenous heat are used.The liver and kidney should be considered.The methods of dissipating phlegm and activating blood circulation could be combined.The treating idea of treating spleen is treating pancreas should be used in preventing and treating diabetes mellitus.
ABSTRACT
This article introduced the application of spleen method in children with pulmonary diseases. It pointed out that for children with acute pulmonary infectious diseases, clearing heat and reducing phlegm should be the treatment for temporary symptoms, strengthening the function of spleen and stomach should be the treatment for essence; recurrent pulmonary diseases should be treated with tonifying spleen to support right qi and adjust ying and wei to strengthen immune system; cough after infection can be treated with reducing phlegm to dispel rest pathogenesis, and mainly strengthen the function of spleen and harmonize zhong. In this article, the typical cases were described, which led to the importance of spleen deficiency in lung disease. Spleen method for treatment of lung diseases has a certain efficacy, which is worth further clinical study.
