Objective:To study the effects of salidroside (Sal) on autophagy of pancreatic cells in rats with severe acute pancreatitis (SAP).Methods:Fifty healthy male Wistar rats were randomly (random number) divided into the sham group, SAP group, Sal 15 group, Sal 30 group and Sal 60 group, 10 rats in each group. The sham group was injected retrogradely normal saline into pancreatic duct, while the 5% sodium taurocholate was injected retrogradely into pancreatic duct to establish severe pancreatitis model in the SAP group and all the Sal groups. Salidroside at different doses were intraperitoneally injected in all the Sal groups at 2 h after surgery. The serum amylase (AMY) activity and plasma tumour necrosis factor-α (TNF-α) level were detected by enzyme-linked immunosorbent assay (ELISA), and Western blot was used to detect the expression of pancreatic tissue protein. The histopathological changes of pancreas were observed under the light microscope. The data were analyzed by SPSS 24.0, and One-way ANOVA was used for comparison between groups. A P value less than 0.05 was considered to be statistically significant. Results:After salidroside intervention, the levels of TNF-α (28.1±0.9) pg/mL, the relative expression of p65 (0.52±0.01), AMY activity (3 801±292) and relative expression of p-mTOR were the lowest in the Sal 60 group (all P<0.05); while the relative expression of LC3 was the highest in the Sal 60 group (all P <0.05). The degree of pathological damage of pancreatic tissues was decreased with the increase of salidroside dose. Conclusions:Salidroside at different doses have protective effects on rats with severe pancreatitis, which seems to be most obvious in the Sal 60 group.

ObjectiveTo study the relationship between the expression of carbohydrate antigen 72-4(CA72-4) in pathology negative lymph nodes from patients with gastric carcinoma and micrometastases. MethodsA total of 385 perigastric negative lymph nodes from 65 patients were immunohistochemically stained with tumor-associated glycoprotein by S-P. ResultsThe lymphatic micrometastases of gastric carcinoma were identified in 14 of 65 patients (21.5%) and in 26 of 385 negative-nodes (6.8%). The incidence of micrometastases was significantly higher in patients with diffuse type than intestinal type(35.5% vs. 8.8%,P

Objective To investigate the effect of interleukin-17 (IL-17) in the gastric cancer cell migration and invasion via regulating epithelial-mesenchymal transition (EMT) and its potential function.Methods (1) Human gastric cancer cell MGC-803 lines in the logarithmic growth phase were stimulated by 0, 1 ng/mL, 10 ng/mL,100 ng/mL and 1μg/mL of IL-17 for 48 hours, and the phenotypic changes were observed.The concentration of IL-17 was selected for follow-on experiments based on the most obvious phenotypic changes.Gastric cancer cell MGC-803 which were stimulated by 100 ng/mL of IL-17 and PBS for 48 hours were allocated into the experimental group and control group, respectively.(2) The expressions of E-cadherin and Vimentin mRNA in gastric cancer cells were assayed through real-time PCR (RT-PCR).(3) The relative expressions of E-cadherin and Vimentin proteins in gastric cancer cells were assayed by the Western blot.(4) The scratch test and Transwell detection were also utilized to study the migration and invasion of gastric cancer cell MGC-803 in vitro.Measurement data with normal distribution were presented as-x ± s and comparison between groups was analyzed using the t test.Results (1) There were significant phenotypic changes in the gastric cancer cell after the different concentration of IL-17 stimulated gastric cancer cell MGC-803 for 48 hours.Cells were changed from polygonal and tight junction to spindle and loosely junction with a deterioration of cell adhesion.Cell phenotypes were gradually changed as the concentration of IL-17 was changed from 0 to 100 ng/mL.Phenotypic changes were the most obvious when 100 ng/mL of IL-17 was used, but these were non-significant as the concentration of IL-17 increased to 1 μg/mL with the death and floating of some cells.(2) The relative expressions of E-cadherin mRNA and Vimentin mRNA in RT-PCR were 0.45 ±0.13 and 1.06 ±0.23 in the experimental group and 2.39 ±0.55 and 1.23±0.41 in the control group, respectively, with significant differences (t =3.811, 2.923, P ＜0.05).(3) The results of Western blot showed the relative expressions of E-cadherin and Vimentin proteins were 0.86 ± 0.17 and 1.56 ± 0.29 in the experimental group and 1.01 ± 0.12 and 0.56 ± 0.17 in the control group, respectively, with significant differences (t =3.551, 3.601, P ＜ 0.05).(4) Cell migration in the 2 groups were detected by the scratch test at 36 hours after scratch test, and the width of scratch in the experimental and control groups were (0.76 ± 0.13) mm and (0.40 ± 0.15) mm, showing a significant difference (t =3.095, P ＜ 0.05).Transwell detection showed number of transmembrane cell in the experimental and control groups were 159 ±28 and 94 ± 18, respectively, with a significant difference (t =3.307, P ＜ 0.05).Conclusion IL-17 can promote the migration and invasion of gastric cancer cells via stimulating alteration of EMT.
