Effect of Qianyang Yuyin Granules on Mesenchymal Transdifferentiation of Renal Tubular Epithelial Cells Induced by TGF-β1 / 中国实验方剂学杂志

ObjectiveBy observing the effect of Qianyang Yuyin granules on the phenotype of renal tubule epithelial cells， the intervention of Qianyang Yuyin granule on renal interstitial fibrosis was investigated. MethodThe renal tubular epithelial cells （HK-2） were treated with different concentrations of transforming growth factor （TGF）-β1 （5， 10， 15， 20， 25 μg·L-1） for 24 hours， and cell morphology and growth state were observed with an inverted phase contrast microscope. The 20 μg·L-1 was selected as the most appropriate concentration of TGF-β1 according to Western blot results for subsequent experiments. HK-2 cells were divided into six groups： blank group， TGF-β1 group （concentration of 20 μg·L-1）， low， medium， and high dose Qianyang Yuyin granule groups （concentration of 0.5， 1， 2 g·L-1）， and valsartan group （1 × 10-5 mol·L-1）. The cell activity was measured by cell proliferation and cell counting kit-8 （CCK-8）. The cell migration ability was detected by scratch test. The Transwell method was used to detect the invasiveness of cells. Western blot was used to detect levels of fibronectin （FN）， E-cadherin， α-smooth muscle activator （α-SMA）， Vimentin， collagen type Ⅰ（Col Ⅰ）， collagen type Ⅳ（Col Ⅳ）， and other related proteins. ResultTGF-β1 stimulating epithelial-mesenchymal transition （EMT） in renal tubular epithelial cells was time- and concentration-dependent. Compared with the blank group， higher concentration in the TGF-β1 group indicates longer intervention time and more obvious long spindle change of cells， and the migration and invasion ability of the cells was significantly enhanced. The protein expression level of FN， α-SMA， Vimentin， Col Ⅰ， and Col Ⅳ increased significantly （P<0.05， P<0.01）， while the expression level of E-cadherin protein decreased （P<0.05）. Compared with the TGF-β1 group， Qianyang Yuyin granule groups could maintain normal cell morphology， and the migration and invasion ability of the cells was inhibited. The protein expression level of FN， α-SMA， Vimentin， Col Ⅰ， and Col Ⅳ decreased （P<0.05， P<0.01）， and the expression of E-cadherin protein was significantly restored （P<0.05）. ConclusionQianyang Yuyin granule can reverse TGF-β1-induced interstitial transformation of renal tubular epithelial cells by reducing the phenotypic expression of mesenchymal cells and increasing the phenotypic expression of epithelial cells.

Formulation optimization and analysis of taste-masking effect of licorzine granules based on sensory evaluation and electronic tongue method / 药学学报

Licorzine granules are common preparations for children zinc deficiency. Considering the long course of treatment, the taste of licorzine granules may become a main factor affecting medication adherence. To date there have been no taste evaluation research into licorzine granules yet. In this study, both sensory evaluation and electronic tongue method were utilized to optimize licorzine granules formulations, evaluate the tastes of licorzine, excipients, optimized formulation in vivo and in vitro. As the results show, bitterness and astringency are the main unpleasant tastes generating from licorzine. Xanthan gum is the main taste-masking excipient, lowering down the bitterness and astringency of licorzine by at least one grade. Good correlation exists between the results of sensory evaluation and electronic tongue method, and an integrated combination of the two helps to obtain objective and rational research conclusions. The adult sensory evaluation study was a research-based clinical trial conducted with informed consent from all subjects in accordance with the ethical requirements of Good Clinical Practice.

Analysis and optimization of policy tools for TCM formula granules in China / 中国药房

OBJECTIVE In order to analyze the current situation of policy tool allocation in China’s TCM formula granule industry， and provide a theoretical basis for the high-quality development of the industry. METHODS Based on the perspective of policy tools，“ TCM formula granules” was used as the keyword to retrieve the official websites of departments directly under the State Council such as the National Medical Products Administration and the National Administration of Traditional Chinese Medicine， as well as provincial governments. The relevant clauses in the policy documents related to TCM formula granules in China from 1993 to 2022 were encoded， and then the application of policy tools was summarized and classified. RESULTS & CONCLUSIONS A total of 12 national documents and 77 provincial documents were ultimately selected， involving 556 relevant policy clauses. It was found that among the relevant policy tools， environmental policy tools had the highest degree of attention， accounting for 62.6%； the proportions of demand-oriented policy tools and supply-oriented policy tools were less， accounting for 17.8% and 19.6%， respectively. From the perspective of policy tools， the use of demand-oriented policy tools in current policy texts was relatively simple， and various policy tools were given low attention； from the perspective of policy objectives， the proportion of use of environmental， demand-oriented and supply-oriented policy tools were not balanced enough. It is suggested to increase the proportion of demand- oriented policy tools to meet international competition； emphasize the use of supply-oriented policy tools to strictly control product quality； consolidate the use of environmental policy tools to standardize quality standards. On this basis， we will coordinate the overall situation， balance the use of various policy tools and promote the development of TCM formula granule industry.

Regulation of Yes associated protein in diabetic nephropathy mice by Yishen Huashi Granule / 中国药理学通报

Aim To explore the protective effect of Yishen Huashi Granule (YSHS) on streptozotocin (STZ) - indueed diabetes nephropathy (DN) in mice and its possible mechanism. Methods The STZ induced DN mice model was established, which was randomly divided into model group, YSHS group and YAP inhibitor Vertepofin group, and the eontrol group was also established. The intervention was started eight weeks after the successful modeling with the course of four weeks. Urine protein concentration before and after intervention in each group as well as serum creatinine (Scr) and blood urea nitrogen (Bun) levels after intervention were measured. After the treatment, the mice were sacrificed, and the pathological changes of glomeruli were observed by light microscope HE staining. The protein expression of YAP, p-YAP S127 and CTGF were detected by Western blot, and the mRNA expressions of YAP, CTGF and podocyte functional proteins nephrin, podophyxin and WT1 were detected by RT-PCR. Results The biochemical indexes of YSHS group were better than those of model group, and HE staining showed that the pathological injury of glomeruli was improved. In the model group the protein expression of YAP, p-YAP (S127) and CTGF as well as the mRNA expression of YAP and CTGF increased, while the mRNA expression of nephrin, podocalyxin and WT1 decreased. After YSHS treatment, the protein expression of YAP, p-YAP S127, CTGF and the mRNA expression of YAP and CTGF decreased, while the mRNA expression of nephrin, podocalyxin and WT1 increased. Conclusions YSHS can reduce urinary protein, protect renal function and alleviate glomerular pathological injury in DN mice. Its possible mechanism may be related to the down-regulation of YAP in renal tissue, the reduction of CTGF expression level and the up-regulation of podocyte protein mRNA expression.

MTT method was used to detect cell proliferation. Flow cytometry was used to detect the apoptosis rate. Real-time P CR was used to detect the expression levels of EGOT and miR-641 mRNA. P cDNA-EGOT and EGOT small interfering RNA (si-EGOT) were transfected into H9 C2 cells respectively, and the cell proliferation and apoptosis rates were detected by the above method. The dual luciferase report experiment verified the targeting relationship between EGOT and miR-641. Western blotting was used to detect the expression levels of Bax, Bcl-2, collagen I (colI), collagen Ⅲ (col Ⅲ), tissue inhibitor of matrix metalloproteinase 2 (TIMP 2), matrix metalloproteinase-2 (MMP -2) . Results Compared with the control group, the cell survival rate of the H / R group reduced significantly (P < 0. 05), the apoptosis rate increased significantly (P < 0. 05), and the protein levels of Bax, c I, col Ⅲ, TIMP 2, and MMP -2 increased significantly (P < 0. 05), the level of Bcl-2 protein reduced significantly (P < 0. 05), the expression level of EGOT reduced significantly (P < 0. 05), the expression level of miR-641 increased significantly (P < 0. 05) . Compared with the H / R group, the cell survival rate of the H / R + Lev-L group, H / R + Lev-M group, and H / R + Lev-H group increased significantly (P < 0. 05), and the apoptosis rate decreased significant (P < 0. 05), the protein levels of Bax, colI, colⅢ, TIMP 2, MMP -2 reduced significantly (P < 0. 05), the level of Bcl-2 protein increased significantly (P < 0. 05), the expression level of EGOT increased significantly (P < 0. 05), the expression level of miR-641 reduced significantly (P < 0. 05), and each index of H / R + Lev-L group, H / R + Lev-M group, H / R + Lev-H group, the difference was statistically significant (P < 0. 05) . The dual luciferase report experiment confirmed that EGOT ccould target and bind to miR-641. The effect of transfecting pcDNA-EGOT and Lev was similar. Transfection of si-EGOT could reduce the effect of Lev on H / R-induced proliferation, apoptosis and fibrosis of H9 C2 cells. Conclusion Levosimendan may promote H / R-induced H9 C2 cell proliferation and inhibit apoptosis and fibrosis by up-regulating EGOT expression and down-regulating miR-641 expression.

AIM: To investigate the effect of Qiteng Xiaozhuo granule on inflammation indexes in rats with chronic glomerulonephritis (CGN) through miR-339-5p. METHODS: CGN model was established by adriamycin (ADR) injection into tail vein of rats. Qiteng Xiaozhu granules (21.6, 10.8, 5.4 g/kg) of different doses were intragastric-fed for 30 days. Pathological changes in kidney tissues of CGN rats were observed by HE staining and electron microscopy. The contents of IL-1β, IL-6, IL-10 and TNF-α in serum and kidney tissue of CGN rats were detected by qRT-PCR, ELISA and Western blot. Relative expressions of miR-339-5p, Syk and p-Syk proteins were detected by Western blot, the relative expressions of miR-339-5p mRNA and Syk mRNA were detected by qRT-PCR. RESULTS: There were thickening of basement membrane and glomerular atrophy in the model group. Compared with the normal group, the expression of miR-339-5p and IL-10 in the model group was significantly down-regulated, while the expression of IL-1β, IL-6, TNF-α and Syk was significantly up-regulated. Qiteng Xiaozhuo granule group could significantly reduce the protein and mRNA expression levels of IL-1β, IL-6, TNF-α, Syk in kidney tissue.CONCLUSION: Qiteng Xiaozhuo granule may down-regulate the expression of inflammatory factors through miR-339-5p in the treatment of inflammatory symptoms in CGN rats.
