Objective To explore the characteristics of the effect of echinacoside on lipid metabolism in type 2 diabetic mice,and to investigate the content of growth factor 21 in liver tissue of diabetic mice,providing further insight into the possible way of regulating blood lipid metabolism in type 2 diabetic mice with Echinacea.Methods Twenty db/db mice (6-week-old) were randomly divided into two groups:experimental group and model group;while six db/m mice (SPF) (6-week-old) were control group.We detected the fasting blood glucose after 2 weeks that was higher than 16.7mmol/L in experiment.Each group was given sterilized distilled water,echinaco side,sterilized distilled water.The serum total,cholesterol,triglyceride,high density lipoprotein,low density lipoprotein,alanine aminotransferase level,aspartate,aminotransferase level,and the liver tissue measurement of fibroblast growth factor 21 levels were detected after eight weeks.Results The model group serum TG,TC and LDL were significantly higher than the control group (P ＜ 0.01).The content of serum HDL was significantly lower than the control group (P ＜ 0.01).Experimental group of serum TG,TC and LDL levels were significantly lower than the model group (P ＜ 0.01).The content of serum HDL was significantly higher than that in the model group (P ＜ 0.01).The expression of FGF21 in model group in liver were significantly lower than that of control group (P ＜ 0.01).The experimental group the expression of FGF21 in mouse liver was significantly higher than that in the model group (P ＜ 0.01).The content of ALT and AST in serum of model group was significantly higher than the control group (P ＜ 0.01).Experimental group serum ALT,AST were significantly lower than the experimental group (P ＜ 0.01).Conclusion After 8 weeks of administration,the serum lipid metabolism disorder of db/db diabetic mice was significantly improved,and the liver function damage was not increased.The mechanism of FGF21 may be related to the improvement of the expression level of liver tissue.

Objective To investigate the expression of MPZL1 in gastric cancer tissues, its relation with the prognosis, and its effects on proliferation and colony formation of gastric cancer. Methods GEPIA and UALCAN databases were used to analyze the expression of MPZL1 in various malignant tumors. The KM Plotter database and UALCAN database were used to analyze the effect of MPZL1 on the overall survival of gastric cancer patients. The expression of MPZL1 protein and the changes of apoptosis-related proteins in gastric cancer cells were detected by Western blot, and the effects of MPZL1 expression on cell proliferation and colony formation were detected by CCK-8 and colony formation assay, respectively. Results MPZL1 was found to be highly expressed in various malignant tumors by GEPIA database. The results of UALCAN and KM Plotter databases analysis showed that MPZL1 was highly expressed in gastric cancer tissues, and might be correlated with the overall survival of gastric cancer patients. The results of CCK-8 and colony formation assay showed that the overexpression of MPZL1 promoted the proliferation and colony formation ability of gastric cancer cells (P < 0.05). Western blot results showed that compared with control group, the expression levels of pro-apoptotic proteins Bad and Caspase-7 in the overexpression group were significantly lower while those in knockdown group were higher. Conclusion MPZL is highly expressed in gastric cancer tissues and promotes the proliferation and colony formation of gastric cancer cells, which may be related to the inhibition of apoptosis.

Objective The objective of this study was to investigate the effect of depression on serum levels of C-reactive protein(CRP)and high-sensitivity C-reactive protein(hs-CRP),and prognosis in liver cancer patients. Methods A total of 251 patients with liver cancer undergoing hepatectomy were enrolled. The hospital anxiety and depression scale( HADS-D) and 9-item patients health questionnaire(PHQ9) were assessed for depression before 3 days for surgery. Patients were divided into depression group(n=95)and non-depression group(n=156) according to the scores. Preoperative serum levels of CRP,hs-CRP,ALT and AST were measured and compared between the depression and non-depression groups. Survival analysis Kaplan-Meier method was used to compare the disease-free survival(DFS)and total survival(OS)between the two groups. Results The serum levels of CRP, hs-CRP,ALT and AST in the depression group were significantly higher than those in the non-depression group(P<0. 05). The follow-up of 3. 5-year showed that 164 patients(65 in depression group and 99 in non-depression group)had recurrence or metas-tasis and 47 patients(22 in depression group and 25 in non-depression group) died. The DFS and OS in the depression group were significantly lower than those in the non-depression group(P< 0. 05). Cox multiple regression analysis showed that liver function grading,BCLC staging and depression were independent risk factors for the prognosis of liver cancer. Spearman correlation analysis showed that patients′degree of depression was positively correlated with serum levels of CRP and hs-CRP(P<0. 05),DFS and OS were negatively correlated with serum levels of CRP and hs-CRP(P<0. 05). Conclusion Depression may mediate elevated serum levels of CRP and hs-CRP,maintain inflammatory response in patients,lead to increased liver function damage,elevate levels of ALT and AST,and thus adversely affect the prognosis of patients with liver cancer.
