AIM:To investigate the effect of cellular Sloan-Kettering Institute(c-SKI)protein expression on myocardial fibrosis in mice treated with andrgrapholide(Andr).METHODS:Male C57 mice were randomly divided into control group,model group[isoprenaline(ISO)group]and ISO+Andr group,with 6 mice per group.The mice in ISO and ISO+Andr groups were subcutaneously injected with ISO,while those in control group were injected with normal sa-line.The mice in ISO+Andr group was intragastrically given Andr,while those in ISO and control groups were given nor-mal saline.The histopathological characteristics of the heart tissue were detected by HE and Masson staining after 8 weeks of administration.The expression levels of c-SKI and extracellular matrix(ECM)-related proteins were detected by immu-nohistochemistry or Western blot.The c-SKI mRNA level was detected by qPCR.Human cardiac fibroblasts(HCFBs)were treated with different concentrations of Andr for 48 h.The cell viability was detected by CCK-8 assay,and the c-SKI and ECM-related protein levels were detected by Western blot.The transdifferentiated cell model was treated with the lowest effective dose of Andr.The cell morphology was observed under a microscope,the levels of c-SKI and ECM-related pro-teins were assessed by Western blot,and the c-SKI mRNA level was detected by qPCR.The transforming growth factor-β1(TGF-β1)-treated HCFBs were treated with the combination of c-SKI knockdown and Andr.The cell viability was detected by CCK-8 assay,and the levels of c-SKI and ECM-related proteins were detected by Western blot.RESULTS:After the intervention of Andr,the myocardial fibers in mice were neatly arranged,the morphology of myocardial cells was basically normal,the cell membrane was intact,and the collagen volume fraction was significantly reduced(P＜0.01).The mRNA and protein levels of c-SKI were significantly up-regulated(P＜0.05 or P＜0.01),and the protein levels of fibronectin 1(FN1),α-smooth muscle actin(α-SMA),vimentin and collagen type I(Col I)were significantly down-regulated(P＜0.01).After 50 μmol/L Andr treatment for 48 h,the viability of HCFBs was significantly decreased(P＜0.01),the pro-tein levels of Col I,α-SMA,vimentin and FN1 were significantly down-regulated(P＜0.01),and c-SKI expression was significantly up-regulated(P＜0.01).Compared with PBS group,the number of the HCFBs in TGF-β1 group increased with flattened and irregular morphological change,and the FN1,α-SMA,Col I and vimentin levels were significantly in-creased(P＜0.01),while c-SKI expression was significantly decreased(P＜0.01).After Andr intervention,the induction effect of TGF-β1 on HCFBs was reversed.Knockdown of c-SKI combined with Andr treatment in HCFBs significantly down-regulated c-SKI expression(P＜0.01),significantly up-regulated FN1,α-SMA,vimentin and Col I levels(P＜0.05),and significantly increased the cell viability.CONCLUSION:Andrgrapholide may affect the TGF-β1 signaling pathway by regulating c-SKI expression,and inhibit the proliferation of myocardial fibroblasts and ECM deposition,thus inhibiting myocardial fibrosis.

Objective Polysaccharide is a major active component in Lycium barbarum.the structure and content of polysaccharide are different among different producing districts.At present,most of the quality control methods of Lycium barbarum polysaccharide construct fingerprint from the aspect of monosaccharide composition,but the quality control of Lycium barbarum polysaccharide only by analyzing monosaccharide composition can not fully explain the relationship between structure and Lycium barbarum polysaccharide.Therefore,we established the Needs methylation method of Lycium barbarum polysaccharide fingerprint to achieve quality control of Lycium barbarum from different places by determining the sugar residue linkage mode of Lycium barbarum polysaccharide on the basis of monosaccharide composition.Methods Lycium barbarum polysaccharide was extracted through water extraction followed by alcohol precipitation,and the Needs methylation,complete acid hydrolysis,reduction by NaBH4,acetylation and other methods combined with GC-MS to determine the sugar residue linkage motif of Lycium barbarum polysaccharide.Result The chromatograms of 18 batches of Lycium barbarum polysaccharides were imported into the Chinese Medicine Chromatographic Fingerprint Similarity Evaluation System(2004 edition),combined with chemometrics to evaluate the differences of Lycium barbarum polysaccharide from different origin.The result of similarity showed that the similarity of three batches of Lycium barbarum polysaccharide from Tibet ranged from 0.551 to 0.569,others were more than 0.929.16 common peaks were marked in chromatogram of sugar residue linkage mode,and 10 of them was identified,they are T-Arap,T-Araf,T-Xylp,1,2-Arap,1,3-Rhap,1,5-Araf,T-Glcp,T-Galp,1,4-Glcp,1,6-Galp.The results of HCA,PCA and PLS-DA analysis divided 18 bathes of Lycium barbarum polysaccharide were divided into three categories,and three signature components were screened,which were T-Araf,1,5-Araf and T-Glcp,to judge the differences of Lycium barbarum polysaccharides from different places.Conclusion The Needs methylation fingerprint of 18 batches of Lycium barbarum polysaccharide was established for the first time.The establishment of the fingerprint can provide experimental data reference for the quality control of Lycium barbarum polysaccharide,and further prove the role of polysaccharide in the quality control of Traditional Chinese Medicine.

Objective:To investigate the correlation between liver stiffness and histopathological changes in a rat model of acute hepatitis using virtual touch tissue imaging quantification (VTIQ) technology.Methods:A total of 100 SPF-grade SD rats were randomly divided into 3 groups: control ( n=30), low-dose ( n=35), and high-dose ( n=35) groups. Acute hepatitis models were induced in the low-dose and high-dose groups using 400 mg/kg and 600 mg/kg of Thioacetamide (TAA), respectively. Liver stiffness parameters of the right median lobe and right lobe were measured using VTIQ technology, Mean-H and Mean-L represent the liver lobes with higher and lower liver stiffness measurments, respectively, while Mean represent the average of the measurements from both liver lobes. Comparative analyses of liver stiffness parameters were performed across three groups and between the two lobes of the liver. The correlations between the Mean values of liver stiffness and semi-quantitative histopathological data were investigated. Ten rats were randomly selected from each of the 3 groups to test the repeatability of VTIQ values before and after euthanasia with intraperitoneal anesthesia. Subsequently, 10 rats after euthanasia from each 3 group were randomly chosen to assess the repeatability of VTIQ measurements for inter-observer and intra-observer variabilities. Results:VTIQ results showed statistically significant differences in Mean, Mean-H, and Mean-L among the 3 groups (all P<0.01). The high-dose group had higher measurements compared to the low-dose and control groups, with significant intergroup differences (all P<0.01). Significant differences in Mean-H and Mean-L were observed between the two liver lobes in both low and high-dose groups (all P<0.01). The Mean value showed significant positive correlations with semi-quantitative histopathological data of hepatocellular edema, periportal inflammatory cell infiltration, macrophage proliferation, and bile duct proliferation ( r=0.391, 0.648, 0.577, 0.542; all P<0.01). Multivariate linear regression analysis indicated that hepatocellular edema, eosinophilic change, and bile duct proliferation significantly and positively predicted the Mean value (β=-0.278, -0.196, -0.333; all P<0.05). There were no significant differences of VTIQ measurements befor and after euthanasia (all P>0.05), with repeatability coefficients of 0.166, 0.182, 0.185 for Mean, Mean-H, and Mean-L, respectively. Post-euthanasia, inter- and intra-observer VTIQ differences remained non-significant (all P>0.05), with Mean, Mean-H, Mean-L coefficients of 0.114, 0.194, 0.165 and 0.206, 0.322, 0.268, respectively. Conclusions:VTIQ technology demonstrates potential clinical value in assessing a rat model of acute hepatitis, offering a new perspective for non-invasive evaluation of acute hepatitis. However, its clinical application requires further validation.

Objective To investigate the correlation between genetic polymorphisms and the risk of rivaroxaban bleeding events in elderly patients with nonvalvular atrial fibrillation(NVAF).Meth-ods A total of 180 elderly NVAF patients treated with rivaroxaban in our department from June 2019 to June 2022 were enrolled,and after 1 year of follow-up,finally,167 patients were included,according to whether bleeding events occurred,they were divided into hemorrhage group(n=31)and control group(n=136).The clinical data and genetic polymorphism were compared between the two groups.Multivariate logistic regression was used to analyze the association between genet-ic polymorphisms and bleeding events in the patients after rivaroxaban treatment.Results Higher frequencies of CYP2C9*1,CYP2C9*3 and VKORC1-GG,but lower frequencies of CYP2C9*2,VKORC1-AA and VKORC1-AG were observed in the bleeding group than the control group(all P＜0.01).Multivariate logistic regression analysis showed that CYP2C9*1,CYP2C9*3 and VKORC1-GG were independent risk factors for bleeding events in elderly NVAF patients taking rivaroxaban(OR=1.880,95％CI:1.126-1.997,P=0.030;OR=1.432,95％CI:1.044-1.964,P=0.026;OR=2.176,95％CI:1.173-4.037,P=0.014),while,CYP2C9*2,VKORC1-AA and VKORC1-AG were protective factors for bleeding events in elderly NVAF patients taking rivar-oxaban.Conclusion Genetic polymorphisms of CYP2C9 and VKORC1 are significantly correlated with the risk of bleeding events in elderly NVAF patients taking rivaroxaban.And CYP2C9*1,CYP2C9*3 and VKORC1-GG genotypes are independent risk factors,while CYP2C9*2,VKORC1-AA and VKORC1-AG genotypes are protective factors.

Drug adulteration and contamination are serious threats to human health therefore,their accurate monitoring is very important.Allopurinol(Alp)and theophylline(Thp)are commonly used drugs for the treatment of gout and bronchitis,while their isomers hypoxanthine(Hyt)and theobromine(Thm)have no effect and affect the efficacy of the drug.In this work,the drug isomers of Alp/Hyt and Thp/Thm are simply mixed with α-,β-,y-cyclodextrin(CD)and metal ions and separated using trapped ion mobility spectrometry-mass spectrometry(TIMS-MS).TIMS-MS results showed that Alp/Hyt and Thp/Thm iso-mers could interact with CD and metal ions and form corresponding binary or ternary complexes to achieve their TIMS separation.Different metal ions and CDs showed different separation effect for the isomers,among which Alp and Hyt could be successfully distinguished from the complexes of[Alp/Hyt+y-CD+Cu-H]+with separation resolution(Rp-p)of 1.51;whereas Thp and Thm could be baseline separated by[Thp/Thm+y-CD+Ca-H]+with Rp-p of 1.96.Besides,chemical calculations revealed that the complexes were in the inclusion forms,and microscopic interactions were somewhat different,making their mobility separation.Moreover,relative and absolute quantification was investigated with an internal standard to determine the precise isomers content,and good linearity(R2＞0.99)was ob-tained.Finally,the method was applied for the adulteration detection where different drugs and urine were analyzed.In addition,due to the advantages of fast speed,simple operation,high sensitivity,and no chromatographic separation required,the proposed method provides an effective strategy for the drug adulteration detection of isomers.
