ObjectiveTo investigate the protective effect of tanshinone I (T-I) on hepatic ischemia-reperfusion injury (HIRI) in mice. MethodsA total of 36 C57BL/6J mice were randomly divided into sham-operation group, ischemia-reperfusion (IR) group, IR+T-I (5 mg/kg) group, IR+T-I (10 mg/kg) group, IR+T-I (20 mg/kg) group, and IR+T-I (40 mg/kg) group, with 6 mice in each group. Each group was given intraperitoneal injection. The mice in the sham-operation group and the IR group were injected with an equal volume of the solvent olive oil; the mice in the IR+T-I groups were administered once a day for 7 consecutive days, a model of 70% HIRI was established at 2 hours after the last administration, and serum and liver samples were collected after 6 hours of reperfusion. Related kits were used to measure the serum level of alanine aminotransferase (ALT) and aspartate aminotransferase (AST) and the content of superoxide dismutase (SOD), malondialdehyde (MDA), caspase-3, and reduced glutathione (GSH) in liver tissue; HE staining was used to observe liver histopathology; the TUNEL method was used to measure the level of hepatocyte apoptosis; immunohistochemistry was used to measure the protein expression of caspase-3 and heme oxygenase-1 (HO-1). A one-way analysis of variance was used for comparison of continuous data between multiple groups, and the least significant difference t-test was used for further comparison between two groups. ResultsCompared with the IR group, the IR+T-I (20mg/kg) group had significant reductions in the serum levels of ALT (192.48±23.67 U/L vs 336.90±41.52 U/L, P＜0.01) and AST (123.19±9.16 U/L vs 206.90±18.81 U/L, P＜0.01), and thus 20 mg/kg was determined as the optimal concentration. Compared with the IR group, the IR+T-I (20 mg/kg) group had significant reductions in MDA (1.34±0.21 μmol/mg vs 3.48±0.95 μmol/mg, P＜0.05) and caspase-3 (0.69±0.97 μmol/mg vs 1.04±0.35 μmol/mg, P＜0.05) and significant increases in SOD (274.47±30.53 U/mg vs 160.29±27.37 U/mg, P＜0.05) and GSH (2.12±0.27 μmol/mg vs 1.03±0.42 μmol/mg, P＜0.05). HE staining showed that the IR group had disordered structure of hepatic lobules and focal or extensive degeneration and necrosis of hepatocytes; compared with the IR group, the IR+T-I (20 mg/kg) group had a reduction in the area of hepatocyte necrosis and a basically complete structure of the liver. Immunohistochemistry showed that compared with the IR group, the IR+T-I (20 mg/kg) group had significant reductions in the number of apoptotic hepatocytes and the protein expression of caspase-3 and a significant increase in the protein expression of HO-1. ConclusionT-I exerts a protective effect against HIRI in mice by inhibiting liver oxidative stress response and hepatocyte apoptosis.

Mitochondrial dysfunction is closely related to the occurrence and development of benign and malignant diseases of the pancreas. Mitochondrial membrane of the respiratory chain electron transfer and energy transfer plays an important role in maintaining normal cellular function. When the respiratory chain was disrupted, the oxidative stress was increased in the cell, and produced a large number of oxide intermediate products which target mitochondrial protein, DNA, etc, lead to mitochondrial dysfunction finally induced acute pancreatitis, pancreatic cancer and other diseases. In addition, mitochondrial homeostasis plays an indispensable role in maintaining the normal function of islet cells. This paper reviewed the research status of mitochondrial dysfunction in pancreatic diseases.

OBJECTIVETo prepare cisPLLAtin-loaded polylactic acid/cnts, and to study the anti-tumor effect of 5-FU-PLLA-CNTs on human gastric carcinoma cell lines(MGC803 and MNK45).

METHODS5-FU-PLLA-CNTs were prepared with ultrasound emulsification. The morphology of 5-FU-PLLA-CNTs was determined by scanning electron microscope(SEM), and its drug loading and drug release curve in vitro were detected by UV-Vis-NIR spectrophotometer. Cells were divided into experiment, positive control and negative control groups. CCK8 method was used to test the cytotoxic effect of 5-FU-PLLA-CNTs in different concentrations on MGC803 and MNK45 cell proliferation. Flow cytometry was employed to measure the apoptotic rate of MGC803 and MNK45 cells before and after the intervention of 5-FU-PLLA-CNTs.

RESULTSDeep layer film of 5-FU-PLLA-CNTs was successfully established, whose drug-load rate was(4.54±0.43)%, entrapment rate was(21.56±2.36)%. In vitro release test showed release rate within 24 h of 5-FU-PLLA-CNTs was 23.9% in a as lowly increasing manner, and accumulating release rate was 85.3% at day 31. CCk8 experiment revealed, as compared to control group, 5-FU-PLLA-CNTs significantly inhibited the proliferation of two cell lines in dose-dependent and time-dependent manner. The best 5-FU-PLLA-CNTs concentration of inhibition for human gastric cancer cell lines was 1 mg/well. Flow cytometry indicated the apoptotic rate of MGC803 and MNK45 cells in experiment group treated by 1 mg/well 5-FU-PLLA-CNTs significantly increased as compared to negative control group (P<0.05), while the difference was not significant as compared to positive control group (P>0.05).

CONCLUSIONThe 5-FU-PLLA-CNTs has good drug sustained-release capacity, and can significantly kill and inhibit the proliferation of MGC803 and MNK45 cell lines.
