Objective: To investigate the effect of astragalus polysaccharides (APS) on proliferation, invasion, apoptosis and drugresistance of cisplatin-resistant colorectal cancer (CRC) HT-29/DDP cells through regulating miR-20a/TGFBR2 axis, and to explore the possible mechanism. Methods: Human CRC HT-29 cells and HT-29/DDP cells were used as non-drug resistant and resistant cell models, respectively; HT-29/DDP cells were randomly divided into four groups, including untreated (HT-29/DDP) group, APS treatment group, miR-20a mimics + APS group, and si-TGFBR2 + APS group. qPCR and Western blotting were applied to detect the expressions of miR-20a and TGFBR2 in HT-29/DDP cells treated with different concentrations ofAPS (0, 0.5, 1.0, 1.5 and 2.0 mg/ml). Subsequently, dual luciferase reporter gene assay was used to verify whether TGFBR2 was a target gene of miR-20a. In addition, CCK-8, Transwell andAnnexin V-FITC/PI double staining were applied to examine the effect ofAPS on proliferation, invasion and apoptosis of HT29/DDP cells. Furthermore, subcutaneous HT-29/DDP cell xenograft model was established on nude mice, and the effect ofAPS on the growth of transplanted tumor was observed. Results: APS significantly inhibited the proliferation of HT-29/DDP cells in a dose-dependent manner (P<0.01). Meanwhile, the expression of miR-20a was down-regulated in HT-29/DDP cells treated with APS, while the expression of TGFBR2 was significantly up-regulated (all P<0.01). Additionally, dual luciferase reporter gene assay result showed that TGFBR2 was a direct target of miR-20a in HT-29/DDP cells and its expression was suppressed. Furthermore, APS could enhance the drug sensitivity of HT-29/DDP cells through downregulating the inhibitory effect of miR-20a on TGFBR2 expression, thereby suppressed proliferation and invasion, and induced apoptosis of HT-29/DDP cells in vitro and in vivo. It was also found that this effect was related with the suppression of PCNA and Bcl-2 proteins and promotion of Bax and Caspase-3 proteins. Conclusion: APS reverses the resistance of HT-29/DDPcells to cisplatin by down-regulating the inhibitory effect of miR-20a on TGFBR2 expression.

OBJECTIVE To establish HPLC characteristic chro matogram of Jianpi yifei biyan prescription standard decoction , to select the quality control index components and determine their contents. METHODS HPLC method combined with Similarity Evaluation System of TCM Chromatographic Fingerprint (2004 edition)were used to establish the characteristic chromatogram of 10 batches of Jianpi yifei biyan prescription standard decoction ;the similarity evaluation and common peaks identification were also carried out. Using common peak area of characteristic chromatogram as variables ,SPSS 26.0 software and SIMCA 14.1 software were used to perfor m cluster analysis (CA),principal component analysis (PCA) and orthogonal partial least squares-discriminant analysis (OPLS-DA);differential components with variable important i n pro jection(VIP)value greater than 1.5 were screened;the contents of cimifugin and differential components were determined by the same method. RESULTS A total of 24 common characteristic peaks were identified , and the similarities of 10 batches of samples were higher than 0.960;eight characteristic peaks were identified by comparison with reference substance. CA and PCA results revealed that the samples were classified into 3 categories.OPLS-DA analysis showed that 3 components with VIP value greater than 1.5, which were prim-O-glucosylcimifugin (peak 2),calycosin 7-O-β-D-glucopyranoside (peak 4) and 5-O-methylvisammioside (peak 6) in descending order. The linear ranges of prim- O- glucosylcimifugin,calycosin 7-O-β-D-glucopyranoside,cimifugin and 5-O-methylvisammioside were 0.010 7-0.213 0,0.007 8- 0.156 0,0.008 0-0.160 0,0.009 8-0.195 0 μg(r>0.999),respectively. RSD values of precision ,repeatability and stability tests (24 h) were all less than 2%. Average recoveries were 105.98%(RSD=1.75%,n=6),98.06%(RSD=3.87%,n=6),96.38%(RSD= 4.03% ,n=6) and 104.17%(RSD=1.27% ,n=6). The contents of the above 4 components in 10 batches of samples were 12.12-18.87,3.86-6.40,3.10-4.27 and 11.17-15.79 μ g/mL,respectively. CONCLUSIONS The established HPLC characteristic chromatographic method is stable and feasible ,it can be used for the quality control of Jianpi yifei biyan prescription standard decoction. Prim- O-glucosylcimifugin,calycosin 7-O-β-D-glucopyranoside,cimifugin and 5-O-methylvisammioside can be used as the index components for quality control of the standard decoction.
