Objective To investigate the mechanism of Gentianopsis paludosa xanthone(GPX)combined with probiotics in the intervention of colon inflammation-tumor transformation in rats by regulating TGF-β1/Smads pathway and inflammatory factors.Methods Ninety rats were divided into the normal group,the model group[drinking sodium dextran sulfate(DSS)for 3 days]and the intervention group by random number table method.The model group was subdivided into the inflammatory stage group,the pre-inflammatory cancer group(DMH injection for 4 weeks),the intermediate inflammatory cancer group(DMH injection for 13 weeks)and the advanced inflammatory cancer group(DMH injection for 21 weeks).The administration group was subdivided into the groups(after the first day of drinking DSS,drugs for each group were given by gavage once a day for 8 weeks)on the basis of the advanced inflammatory cancer group,including the GPX group(GPX 69.3 mg/kg),the probiotic group,the combined group(GPX+probiotics 400 mg/kg)and the thalidomide group(thalidomide 13.5 mg/kg).The disease activity index(DAI),colon length and wet mass index were compared between all groups.Characteristics of colon tumors were observed,and pathological changes of colon were observed by HE staining.The expression levels of transforming growth factor(TGF)-β1,Smad4,Smad7,interleukin(IL)-6 and tumor necrosis factor(TNF)-α were detected by Western blot assay and enzyme-linked immunosorbent assay,respectively.Results Compared with the advanced inflammatory cancer group,the administration groups showed an increase in colon length,the expression levels of TGF-β1 and Smad4 protein,a decrease in colon wall thickness,wet mass index,maximum tumor diameter,the levels of Smad7,IL-6,TNF-α,and DAI score decreased in the GPX group and the combined group(P＜0.05).The structure and morphology of intestinal mucosa were improved in the GPX group,the probiotic group and the combination group,and the structure of colonic crypt and goblet cell number were increased.Compared with the probiotic group and the GPX group,the colon wall thickness,colon wet mass index and tumor number were decreased,the protein expression levels of TGF-β1 and Smad4 were increased,and levels of IL-6 and TNF-α were decreased in the combination group(P＜0.05).Conclusion GPX combined with probiotics could inhibit the transformation of colon inflammation-tumor,and the mechanism may be related to the regulation of TGF-β1/Smads pathway and the inhibition of pro-inflammatory factors of IL-6 and TNF-α.

Objective To construct a nomogram prediction model for the risk of mild cognitive impair-ment (MCI) in elderly people aged ≥ 60-year-old.Methods A total of 502 elderly permanent residents in Guangxi were selected as the research subjects by the multi-stage stratified random sampling method,and the general situation questionnaire and the Beijing edition of MoCA-BJ scale were used to investigate the elderly people,and their anthropometric indicators were collected.The minimum absolute shrinkage rate and selection operator (LASSO) regression were used to screen the characteristic variables.The MCI risk nomogram pre-diction model was constructed.The receiver operating characteristic (ROC) curve and calibration curve were adopted to conduct the fitting effect test on the prediction model.Results Among the 502 elderly people,244 cases (46.04％) had the normal cognition and 258 cases (48.68％) had MCI.The logistic regression analysis showed that the age,education background,month income,children support,calf circumference,BMI and body fat index were the influencing factors of MCI in the elderly people,and the nomogram prediction model of the MCI risk in the elderly people was constructed by these seven variables.The area under the ROC curve (AUC) of the model was 0.790 (95％CI:0.750-0.829),the sensitivity was 0.64,the specificity was 0.62,the C-index index was 0.790,and the model fitting x2=8.111,P=0.454,the predictive value was basically consistent with the actual value.Conclusion The nomogram prediction model of MCI risk in the elderly peo-ple is successfully constructed with good predictive effect.

OBJECTIVE: To explore the expression patterns of transcription factor SOX12 in lung adenocarcinoma and its significance in the diagnosis and prognosis of the malignancy. METHODS: Large cancer genome databases were used to analyze SOX12 expression level in lung adenocarcinoma. Immunohistochemistry (IHC) and semiquantitative PCR were used to detect the expression of SOX12 in 36 specimens of lung adenocarcinoma tissues, 15 adjacent tissues and 21 normal lung tissues. The prognostic value of SOX12 in lung adenocarcinoma and lung squamous cell carcinoma were analyzed using Kaplan-Meier Plotter database, and the relationship between SOX12 expression and the overall survival (OS) and progression free survival (PPS) of the patients were analyzed. RESULTS: Analysis of TCGA database and GEO (GSE40419) database showed that SOX12 expression levels were significantly higher in in lung adenocarcinoma than in normal lung tissues ( < 0.001). The results of IHC and semiquantitative PCR revealed that SOX12 was expressed at significantly higher levels in lung adenocarcinoma than in normal lung tissues ( < 0.001). Kaplan-Meier survival analysis showed that patients with lung adenocarcinoma positive for SOX12 had a significantly shorter OS and PPS time than those negative for SOX12 ( < 0.05), but SOX12 positivity did not significantly affect OS and PPS of patients with lung squamous cell carcinoma. CONCLUSIONS High expression levels of SOX12 in lung adenocarcinoma are significantly associated with a poor OS of the patients, suggesting the value of SOX12 to assist in early diagnosis and prognostic evaluation of lung adenocarcinoma.

Objective To explore the effect of lipoprotein(a) [Lp(a)] on in-stent restenosis and non-target coronary lesions in coronary artery disease (CAD) patients implanted with drug-eluting stents. Methods One hundred and seventy-four patients, diagnosed as CAD and underwent percutaneous coronary intervention (PCI) with the implantation of drug-eluting stents (DES), were enrolled in present study; all of them were performed another elective PCI or revascularization within 1-4 years after their previous procedures. Thirty-one of enrolled patients were discovered to have in-stent restenosis. The relationship between Lp(a) and in-stent restenosis and the development of non-target coronary lesions were analyzed in groups stratified by the presence of in-stent stenosis or Lp(a) levels, and the independent risk factors of both in-stent restenosis and non-target lesions were also analyzed by multivariate logistic regression analysis. Results In CAD patients with DES, Lp(a) level in patients with in-stent restenosis showed a significant increase than those with the Lp(a) level non-restenosis [(437.57±391.60) mg vs. (279.46±288.06) mg, P=0.04]. In following analysis comparing lipid profiles and coronary angiography results between low and high Lp(a) groups, the percentage of triple-vessel disease and left main plus triple-vessel disease appeared to be statistically higher in high Lp(a) group than those in low Lp(a) group (P=0.022). Multivariate logistic regression analysis revealed that high level of Lp(a) and much number of stents implanted were the independent risk factors for in-stent restenosis of DES. In comparing the characteristics of coronary angiography and results of quantitative coronary angiography, number of cases with non-target lesions, presence of in-stent restenosis, minimal lumen diameter and in-stent late lumen loss were all significantly higher in high Lp(a) group than those in low Lp(a) group (P<0.05), and high level of Lp(a) was again proved to be an independent risk factor for non-target lesions in patients with DES (P=0.001). Conclusion Elevated Lp(a) level is an independent risk factor for both in-stent restenosis and the development of non-target coronary lesions, and is closely related to the relapse and aggravation of coronary artery disease.
