AIM: Direct exposure of cells to reactive oxygen species can induce apoptosis. In this study we investigate how oxidative stress induces cell death in HepG2 cells and characterize the molecular events involved. METHODS: Oxidative stress was created by exposing HepG2 cells to 2 mmol/L H2O2. Apoptosis was determined by analysis of DNA fragmentation by agarose gel electorphoresis. The mitochondrial membrane potential was analyzed using DePsipher fluorescent staining and the expression of cytochrome c in the cytosolic fraction was measured by Western blotting analysis.The caspase activity was detected using fluorometric assay kit by a fluorescence microplate reader. RESULTS: When HepG2 cells were treated with 2 mmol/L H2O2, the cells displayed DNA fragmentation, a typical feature of apoptosis, after 12 h. The mitochondrial membrane potential appeared different in two group of cells. H2O2 -treated cells appeared green fluorescence as early as 4 h, which represents de - energized mitochondria, the untreated cells appeared red fluorescence,a feature of mitochondria with intact membrane potential. In treated cells, the expression of cytochrome c increased and accumulated in cytosolic fraction with treatment time, caspase - 3 activity increased by 6.7 - fold ( P ＜ 0.01 ) at 8 h and caspase -9 activity increased by 3.6 - fold (P ＜ 0.01 ) at 12 h, respectively, however, the activity of caspase - 8 remained unchanged. CONCLUSION: These findings suggest that oxidative stress can induce apoptotic cell death in HepG2 cells, and the mechanism is related to mitochondrial pathway, which activates caspase -9 and- 3, but not caspase -8.

Aim To investigate the role of endoplasmic reticulum stress in adenosine induced HepG2 cell apoptosis.Methods HepG2 cells were treated with different concentrations of ADO for 36 h,and the effect of ADO on cell proliferation was measured by MTT assay.Cell nuclei DAPI staining was used to detect the nuclei change after being treated with different concentrations ADO for 36 h or 2.0 mmol?L-1 ADO for different time.The effect of ADO on HepG2 cell cycle was analysed by flow cytometry after being treated with 2.0 mmol?L-1 ADO for 12 h or 24 h.Translocation of CHOP and Caspase-3 were measured by immunofluorescence after being treated with 2.0 mmol?L-1 ADO for 36 h.The proteins expressions of CHOP,Caspase-4,Caspase-3 and JNK were assayed by western blot.Results The viability of HepG2 cell decreased in a dose-dependent manner;the relative cell viability of 0.5,1,2,4,6 mmol?L-1 decreased by 13.48%?0.12%,27.92%?0.25%,35.21%?0.42%,51.46%?0.24%,71.42%?0.58%,compared with the control group respectively.The nuclei of HepG2 cells treated with different ADO concentrations or 2.0 mmol?L-1 ADO showed condensation,rounding and shrinkage,then fragmentation,which demonstrated cell apoptosis.After being treated with 2.0 mmol?L-1 ADO for 12 h or 24 h,cell cycle analysis showed sub-G1 phase increased;the apoptotic ratio of control,12 h and 24 h was 1.55%?0.12%,10.96%?0.07% and 21.04%?0.26% respectively.Immunofluorescence assay showed the CHOP and Caspase-3 translocation to the nuclei after being treated with 2.0 mmol?L-1 ADO.The expressions of CHOP,Caspase-3 and Caspase-4 increased after being treated with different concentrations ADO for 36 h,while the expression of JNK did not change.Conclusion Endoplasmic reticulum stress is involved in adenosine-induced HepG2 cell apoptosis.

The Internet Public Opinion Monitoring and Early Warning System for medical and health industry was designed and implemented due to the frequent occurrence of Internet public opinion, which has all-directional data collecting and analyzing functions, including big data collection, near duplicate detection, spam filtration, key public opinion early warning, region identification and tendency analysis, and can thus provide evidence for relevant departments to take effective measures for the control of Internet public opinion.

Objective To investigate the value of fractional contrast medium bolus injection in improving the quality of CT portography.MethodsA total of 42 patients were randomly divided into two groups which were all given iohexol (350mgI/mL) as the contrast medium.20 patients in the group A were injected with conventional method (dosage of 100ml, rate of 4mL/s).The group B (22 patients) were treated with fractional contrast medium bolus injection, the first phase with 60mL contrast medium (rate of 4mL/s) and the second phase (10s delayed) with 40mL contrast medium (rate of 4m/s).The tube was washed by 20mL saline with the same rate of injection at both phases.The CT values and the image quality of the branches of the portal vein were evaluated according to the original and postprocessed images.Independent samples test was used to compare the CT values of the portal vein, splenic vein, superior mesenteric vein, hepatic parenchyma and portal vein-liver parenchyma.The subjective evaluation scores of the image quality were compared by wilcoxon.ResultsThe CT values of the portal vein, splenic vein and portal vein-liver parenchyma in the group B were significantly higher than that in the group A (t=3.317,3.523,P<0.01).There was no significant difference in CT values of hepatic parenchyma and superior mesenteric vein between the two groups.Subjective quality score in the group B was superior to that in the group A, and the difference was statistically significant.T The two evaluation physicians agreed well.ConclusionThe technique of fractional contrast medium bolus injection can significantly improve the image quality of CT portograghy.

[ ABSTRACT] AIM:To investigate the effects of tanshinone IIA ( Tan IIA) on proliferation, apoptosis and its mo-lecular mechanism in human hepatoma HepG2 cells under hypoxic condition.METHODS:Hypoxia model was established by treatment with cobalt chloride ( CoCl2 ) .The cells were divided into normoxia control group, hypoxia control group and hypoxia combined at different concentrations of Tan IIA groups.After HepG2 cells were incubated with different concentra-tions of Tan IIA (0.5, 1.0, 2.0, 5.0 and 10.0 mg/L) for 24 h, 48 h and 72 h under hypoxic condition, the cell prolifer-ation was determined by MTT assay.After Tan IIA was added to the media at different concentrations for 24 h and 48 h, the apoptotic cells were observed by Hoechst 33258 staining.The protein levels of hypoxia-inducible factor 1 alpha (HIF-1α) , vascular endothelial growth factor ( VEGF) and wild-type P53 were detected by Western blotting after cultured with different concentrations of Tan IIA for 48 h.RESULTS:Tan IIA inhibited the proliferation of HepG2 cells in a dose-and time-dependent manner.Tan IIA induced the typical morphology of apoptotic cells and increased the apoptotic rate in a dose-and time-dependent manner after treatment with 1.0 mg/L~5.0 mg/L for 24 h and 48 h under hypoxic condition. The protein levels of HIF-1αand VEGF were weakly expressed in HepG2 cells under normoxia but up-regulated after incu-bated under hypoxia for 48 h.The protein expression of HIF-1αand VEGF were decreased with the increase in the concen-tration of Tan IIA under hypoxia.The protein expression of wild-type P53 was increased with the increase in the concentra-tions of Tan IIA under hypoxia.CONCLUSION:Tan IIA significantly inhibits the proliferation and induces the apoptosis of human hepatoma HepG2 cells under hypoxia, which may be related to the down-regulation of HIF-1αand VEGF and up-regulation of wild-type P53.

OBJECTIVE: To provide prenatal diagnosis for a pregnant women carrying a chromosome translocations using single nucleotide polymorphism array (SNP-array). METHODS: The fetus and its parents were subjected to chromosome karyotyping and SNP array analysis. RESULTS: A Xp22.12 microduplication was identified in the fetus with a size of 496.3 kb. Search of literature and database indicated the microduplication to be variant of unclear significance. The phenotypically normal mother has carried a 505.8 kb duplication at the same position. The father was normal for the testing. The couple decided to continue with the pregnancy and gave birth to a healthy girl at full-term. No abnormality was found during the follow-up. CONCLUSION The Xp22.12 microduplication encompassed part of RPS6KA3 gene, which shows various features of Coffin-Lowry syndrome. Female with Xp22.12 microduplications may be asymptomatic carriers due to X chromosome inactivation. Our case may provide data for delineating the phenotype-genotype correlation of Xp22.12 microduplication.
