BACKGROUND:The Wnt/β-catenin signaling pathway is one of the most important signaling pathways in stem cel regulation, which is involved in regulation of cel proliferation and differentiation. OBJECTIVE:To investigate the expression of Wnt/β-catenin main signaling molecule in inflammatory bowel tissues treated with bone marrow mesenchymal stem cel transplantation. METHODS:2,4,6-Trinitrobenzene sulfonic acid was used for establishing inflammatory bowel diseases rat models. Bone marrow mesenchymal stem cels labeled with green fluorescent protein were transplanted into rat modelsviatail vein. Normal saline was injected as control. The expression of Wnt/β-catenin signaling molecule was detected in the large intestine tissue of inflammatory bowel disease rat models by quantitative RT-PCR at 14 and 28 days after transplantation. RESULTS AND CONCLUSION:Real-time quantitative PCR results showed that the expression of Wnt3a andβ-catenin in the inflammatory bowel tissue increased significantly (P < 0.05), while no difference in the expression of c-myc (P > 0.05). The expressions of Wnt3a, β-catenin and c-myc in the transplantation group were significantly lower than those in the control group after transplantation (P <0.05). These findings indicate that the Wnt/β-catenin signaling pathway plays important roles in inflammatory bowel disease and repair after bone marrow mesenchymal stem cel transplantation, while this pathway may promote stem cels differentiating into intestinal epithelium, promote recovery from inflammatory bowel disease, repair inflammatory area, and restore intestinal tissue homeostasis.

Aim To investigate the effect of Jinlida on cholesterol-related genes in skeletal muscle in fat-in-duced insulin resistance ApoE-/ - mice. Methods Ten male C57 BL/6 J mice were selected as normal group ( NF );50 male ApoE-/ - mice with a high-fat feeding after 16 weeks ( HF) were divided into model group, rosiglitazone ( LGLT ) , Jinlida low dose group ( JLDL, 0. 95 g · kg-1 · d-1 ) , Jinlida medium dose group ( JLDM, 1. 9 g·kg-1 ·d-1 ) , Jinlida high dose group (JLDH, 3. 8 g·kg-1·d-1), which were per-formed intragastric administration for 8 weeks. Oil red O staining of mouse skeletal muscle was used for fat ac-cumulation. Insulin receptor ( INSR) , insulin receptor body substrate-1 ( IRS-1 ) , low-density lipoprotein re-ceptor ( LDLR ) , cholesterol sensor ( SCAP ) mRNA and protein expression in mouse skeletal muscle were measured by quantitative reverse transcription PCR ( RT-PCR ) and Western blot. Results Compared with NF group, fasting blood glucose ( FBG) , choles-terol ( TC ) , triglyceride ( TG ) and low density lipo-protein cholesterol ( LDL-C ) of HF mice were signifi-cantly elevated, while high-density lipoprotein ( HDL-C ) significantly decreased ( P < 0. 05 ) . Compared with HF group, Jinlida group could reduce to varying degrees FBG, TC, TG and LDL-C in mice, and in-crease HDL-C ( P <0. 05 ) . Jinlida could downgrade fasting serum insulin ( FINS ) level, and improve the insulin sensitive index ( ISI ) ( P < 0. 05 ) . Jinlida could obviously improve skeletal muscle fat accumula-tion of mice. Compared with NF group, skeletal mus-cle INSR, IRS-1, LDLR mRNA and protein levels of HF group were significantly decreased ( P <0. 05 ) , while SCAP mRNA and protein level increased signifi-cantly (P<0. 05). Compared with HF group, Jinlida could increase to varying degrees INSR, IRS-1, LDLR mRNA and protein levels ( P < 0. 05 ) , and lower SCAP mRNA and protein levels ( P<0. 05 ) . Conclu-sion Jinlida can alleviate fat-induced insulin resist-ance in ApoE-/ - mice through regulation of cholester-ol-related gene expression.

Objective:To investigate the efficacy prediction and evaluation value of neoadjuvant chemotherapy for breast cancer by using dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) texture analysis.Methods:The clinical data of 63 patients with pathologically confirmed breast cancer in the Shanxi Provincial Cancer Hospital from September 2014 to October 2018 were retrospectively analyzed. All the patients underwent DCE-MRI before and after neoadjuvant chemotherapy and they were divided into the treatment-effective group (40 cases) and the treatment-ineffective group (23 cases) according to the postoperative pathological results. Texture parameters from volume transfer (Ktrans) maps of DCE-MRI before neoadjuvant chemotherapy and after 4-8 cycles of neoadjuvant chemotherapy were measured by using Omni-Kinetics software. The comparison of texture parameters between the two groups was performed by using independent sample t test or Mann-Whitney U test. The receiver operating characteristic curve was drawn and the prediction efficiency of these texture parameters in the therapeutic efficacy of neoadjuvant chemotherapy for breast cancer according to the corresponding area under the curve (AUC) was evaluated.Results:A total of 33 texture parameters were enrolled, and finally 29 texture parameters were retained. Before and after neoadjuvant chemotherapy 22 texture parameters had statistically significant difference in 63 patients (all P < 0.05). There was a statistically significant difference in 9 texture parameters between the two groups before neoadjuvant chemotherapy (all P < 0.05), including uniformity [0.17 (-0.06, 0.34), 0.39 (0.22, 0.48), Z = -2.955, P < 0.01], histogram energy [169.88 (129.36, 288.77), 116.22 (93.77, 151.95), Z = 3.241, P < 0.01] and histogram entropy [6.33 (5.71, 6.69), 6.68 (6.52, 6.97), Z = -2.991, P < 0.01]. After neoadjuvant chemotherapy, 8 of the 29 texture parameters between the two groups had statistically significant differences (all P < 0.05), including histogram entropy (6.00±0.71, 6.46±0.49, t = -2.720, P < 0.01), entropy (6.81±1.40, 8.02±1.48, t = -3.238, P < 0.01), Haralick entropy [0.49±0.10, 0.55±0.10, Z = -2.613, P < 0.01], grey level non-uniformity (GLN) [1.68 (1.42, 3.37), 4.92 (3.58, 8.50), Z = -3.897, P < 0.01], run length non-uniformity (RLN) [100.38 (65.31, 305.75), 359.75 (176.75, 655.00), Z = -4.033, P < 0.01]. There were statistical differences in 8 parameters change rate before and after neoadjuvant chemotherapy between the two groups (all P < 0.05), mainly including ΔGLN [-0.72 (-0.78, -0.60), -0.23 (-0.55, 0.36), Z = -4.554, P < 0.01], ΔRLN [-0.71 (-0.85, -0.52), -0.33 (-0.48, -0.10), Z = -4.454, P < 0.01], Δhigh grey level run emphasis (HGLRE) [1.28 (0.39, 3.46), 0.11 (-0.24, 0.86), Z = 3.184, P < 0.01]. According to the ROC curve, AUC of GLN, RLN, ΔGLN and ΔRLN after neoadjuvant chemotherapy was 0.80, 0.81, 0.85 and 0.84, respectively. Conclusion:Some texture parameters obtained from DCE-MRI Ktrans map can predict and evaluate the efficacy of neoadjuvant chemotherapy in breast cancer.

Objective:To investigate the value of preoperative breast MRI combined with axillary ultrasound in predicting lymphovascular invasion (LVI) of breast invasive ductal carcinoma.Methods:The clinical, pathological and imaging features of 160 female patients [age 25-74(49±10)years] with breast invasive ductal carcinoma from March 2014 to December 2017 in Shanxi Cancer Hospital were retrospectively analyzed. According to the LVI status determined by postoperative pathology, 160 patients were divided into LVI positive group (56 cases) and LVI negative group (104 cases). The clinical characteristics, pathological characteristics and imaging features of LVI positive group and LVI negative group were compared by the independent t test, Mann-Whitney U test or χ 2 test. Multivariate logistic regression analysis was performed to identify independent predictors for predicting LVI and construct a predictive model. The receiver operating characteristic (ROC) curve and area under the curve (AUC) was used to evaluate the discrimination of the prediction model, and the Hosmer-Lemeshow test was used to evaluate its calibration. Results:There was no significant difference in age, menopausal status, estrogen receptor, progesterone receptor, human epidermal growth factor 2, Ki67 index and molecular subtype between LVI positive group and negative group ( P>0.05). Tumor size, peritumoral edema, adjacent vessel sign, multifocality or multicentricity, peritumoral maximum-apparent diffusion coefficient (ADC), peritumour-tumour ADC ratio, MRI axillary lymph node status and ultrasound axillary lymph node status between LVI positive group and LVI negative group showed significantly statistical difference ( P<0.05). Variables with significant difference in the univariate analysis were entered into multivariate logistic regression analysis to explore predictors for LVI. Peritumoral edema (OR=3.367, 95%CI 1.382-8.201, P=0.008), multifocality or multicentricity (OR=4.026, 95%CI 1.268-12.776, P=0.018), high peritumoral-tumor ADC ratio (OR=7.321, 95%CI 2.226-24.079, P=0.001) and positive ultrasound axillary lymph node (OR=6.779, 95%CI 2.819-16.303, P<0.001) were independent predictors for predicting LVI. A logistic regression model was constructed using the above four indicators, and ROC showed AUC of this model for predicting LVI was 0.882, superior to any of the single indicator ( P<0.05); its sensitivity was 80.36% and specificity was 84.62%. Hosmer-lemeshow test showed that the prediction model had good calibration ( P=0.503). Conclusion:The combined prediction model constructed by preoperative breast MRI and axillary ultrasound could help to predict the LVI status of breast invasive ductal carcinoma.
