ObjectiveTo explore the effect of Qingre Huayu Jianpi prescription （QHJ） on colitis-associated colorectal cancer （CAC） in mice， and its related mechanism. MethodC57BL/6 mice were randomly divided into four groups including the normal， model， QHJ low-dose （QHJ-L， 10 g·kg^-1）， and QHJ high-dose （QHJ-H， 40 g·kg^-1） groups. Azoxymethane （AOM） and dextran sodium sulfate （DSS） were combined to chemically build a CAC mouse model for 14 weeks. Each drug group was given intragastrically from the 5^th week to the 14^th week， once per day. An equal volume of water was fed to the normal and model groups. The mouse survival rate， colon length， weight， and pathological alterations were assessed. The protein expressions of Wnt-3a protein signaling （Wnt3a）， β-catenin， Non-phosphor-β-catenin （Non-p-β-catenin）， and cholesterol-binding glycoproteins 133 （CD133） were detected by Western blot. The localization and expression of the cluster of differentiation （CD） 80 and CD11 antigen-like family member B （CD11b） were detected by immunohistochemistry （IHC）. The colon organoids derived from CAC mice were isolated and cultured to detect the expression of Wnt signaling pathway-related proteins. ResultThe survival rate of the CAC mice was improved by QHJ treatment and the number of colon tumors was inhibited significantly. Compared with those in the normal group， the expression levels of Wnt3a， β-catenin， Non-p-β-catenin， and CD133 in colon tissues in the model group were significantly increased （P<0.05， P<0.01）. Compared with those in the model group， the levels of Wnt3a and β-catenin in the QHJ-L group were significantly decreased （P<0.01）， and the protein levels of Wnt3a， β-catenin， Non-p-β-catenin， and CD133 in the QHJ-H group were significantly decreased （P<0.05， P<0.01）. Meanwhile， the expression level of CD11b in the model group was significantly increased compared with that in the normal group while the CD80 level was significantly decreased （P<0.05， P<0.01）. Compared with those in the model group， CD11b in QHJ-L and QHJ-H groups was significantly decreased， and CD80 was significantly increased（P<0.05， P<0.01）. The expressions of Non-p-β-catenin and CD133 in colonic organoids of CAC model mice were significantly increased， while QHJ treatment could inhibit the expressions of Non-p-β-catenin and CD133 in colonic organoids （P<0.01）. ConclusionQHJ could inhibit the inflammation-cancer development in CAC mice， the mechanism of which might be related to regulating the microenvironment and inhibiting the over-activation of Wnt signaling.

Objective To explore the possible mechanism of emodin in inhibiting proliferation,migration,and invasion of AGS cells and in suppressing the expressions of YAP1 and FOXD1.Methods Normal gastric cell GES-1 and gastric cancer cell AGS were cultured with different concentrations of emodin.CCK8 test,scratch test and Transwell assay were used to verify changes in the biological phenotype of AGS cells.TCGA database was applied to analyze expressions of HK2,YAP1 and FOXD1 in gastric cancer tissues and normal gastric tissues.Western blotting method was used to detect the impacts of emodin on HK2,YAP1 and FOXD1 proteins in AGS cells.Exogenous pyruvic acid was added to verify the changes in YAP1 and FOXD1.Results The IC50 of emodin was significantly higher in GES-1 cells than in AGS cells(P<0.05).CCK8 proliferation test,scratch test,and Transwell assay showed that emodin significantly inhibited the biological abilities of AGS(P<0.05 for comparisons).Analysis on the TCGA bioinformatics database found that the expression of key enzymes HK2 in the glycolysis pathway and oncogenes YAP1 and FOXD1 was significantly higher in gastric cancer tissues than in normal gastric tissues(P<0.05 for comparisons).Emodin significantly inhibited the protein expressions of key glycolytic enzymes HK2 and oncogenes YAP1 and FOXD1(P<0.05 for comparisons).With supplement of exogenous glycolytic metabolite pyruvate,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased(P<0.05 for comparisons).Conclusions Emodin has a significant pharmacological inhibitory effect on gastric cancer AGS cells,markedly suppressing their biological phenotype.Emodin not only significantly inhibits the key enzyme HK2 in glycolysis metabolism,but also the protein expressions of oncogenes YAP1 and FOXD1.With the addition of exogenous pyruvate to enhance the glycolytic metabolic pathway,the protein expressions of oncogenes YAP1 and FOXD1 significantly increased.The above results suggest a close association of YAP1 and FOXD1 with glycolytic metabolism.Emodin may inhibit oncogenes YAP1 and FOXD1 through the glycolytic metabolism of gastric cancer AGS cells.

[Objective]To evaluate the changes in cardiac structure and ventricular function in patients with Ander-son-Fabry Disease(AFD)by two-dimensional speckle tracking echocardiography(2D-STE)and to explore the character-istics of their early cardiac involvement.[Methods]All 45 patients diagnosed with AFD in this observational study under-went routine ultrasonic cardiogram(UCG)examination and 2D-STE.The patients were divided into 2 groups based on UCG measurements:with left ventricular hypertrophy(interventricular septum or posterior left ventricular wall thickness≥12 mm)and without left ventricular hypertrophy.TomTec software was used to analyze the echocardiographic images,then the baseline data,UCG routine parameters and myocardial strain of the two groups were compared.[Results]The study in-cluded 27 males(60.0%)and 18 females(40.0%),with an average age of(32.33±16.11),17 cases(37.78%)with left ventricular hypertrophy and 28 cases(62.22%)without left ventricular hypertrophy.All patients had normal left ventricu-lar ejection fraction(LVEF)(>50%).Compared with those without left ventricular hypertrophy,patients with left ventric-ular hypertrophy had significantly more target organ involvement,significantly higher E/A and average E/E' ratios(P<0.05).No statistical difference was found in global and segmental longitudinal strain(LS),circumferential strain(CS)and radial strain(RS)of the endocardium and myocardium between the two groups(all P>0.05).There were lower abso-lute values of global and segmental LS and CS in the myocardium than in the endocardium(all P<0.05),and higher abso-lute values of LS and RS in the mid segment than in the basal and apical segments(all P<0.05).[Conclusions]There is no significant association between early systolic dysfunction and left ventricular wall thickness.2D-STE strain can be used to detect AFD in the early stage.Ventricular wall myocardium exhibits more serious involvement than endocardium and mid segment was less involved than the apical and basal segments.

Objective:To retrospectively analyze the treatment status of tyrosine kinase inhibitors (TKI) in newly diagnosed patients with chronic myeloid leukemia (CML) in China.Methods:Data of chronic phase (CP) and accelerated phase (AP) CML patients diagnosed from January 2006 to December 2022 from 77 centers, ≥18 years old, and receiving initial imatinib, nilotinib, dasatinib or flumatinib-therapy within 6 months after diagnosis in China with complete data were retrospectively interrogated. The choice of initial TKI, current TKI medications, treatment switch and reasons, treatment responses and outcomes as well as the variables associated with them were analyzed.Results:6 893 patients in CP ( n=6 453, 93.6%) or AP ( n=440, 6.4%) receiving initial imatinib ( n=4 906, 71.2%), nilotinib ( n=1 157, 16.8%), dasatinib ( n=298, 4.3%) or flumatinib ( n=532, 7.2%) -therapy. With the median follow-up of 43 ( IQR 22-75) months, 1 581 (22.9%) patients switched TKI due to resistance ( n=1 055, 15.3%), intolerance ( n=248, 3.6%), pursuit of better efficacy ( n=168, 2.4%), economic or other reasons ( n=110, 1.6%). The frequency of switching TKI in AP patients was significantly-higher than that in CP patients (44.1% vs 21.5%, P<0.001), and more AP patients switched TKI due to resistance than CP patients (75.3% vs 66.1%, P=0.011). Multi-variable analyses showed that male, lower HGB concentration and ELTS intermediate/high-risk cohort were associated with lower cytogenetic and molecular responses rate and poor outcomes in CP patients; higher WBC count and initial the second-generation TKI treatment, the higher response rates; Ph + ACA at diagnosis, poor PFS. However, Sokal intermediate/high-risk cohort was only significantly-associated with lower CCyR and MMR rates and the poor PFS. Lower HGB concentration and larger spleen size were significantly-associated with the lower cytogenetic and molecular response rates in AP patients; initial the second-generation TKI treatment, the higher treatment response rates; lower PLT count, higher blasts and Ph + ACA, poorer TFS; Ph + ACA, poorer OS. Conclusion:At present, the vast majority of newly-diagnosed CML-CP or AP patients could benefit from TKI treatment in the long term with the good treatment responses and survival outcomes.
