Objective To detect the expression of mitochondrial dynamics proteins (Mfn2 and Drp1) in thyroid squa?mous carcinoma cell line SW579 and the effects of Mitochondrial division inhibitor, Mdivi-1, on proliferation, apoptosis and invasion of SW579. Methods In SW579 and Nthy-ori 3-1 cell lines, the expression levels of Mfn2 and Drp1 were deter?mined by western blot while the transcription level of Mfn2 and Drp1 mRNA were measured by RT-PCR. Then, SW579 cells were divided into control group (DMSO, 0.1%) and Mdivi-1 low, medium and high dose groups (Mdivi-1 of 15,30 and 45μmol/L were incubated with cells for 16 hours respectively). Then the ability of cell proliferation was detected using MTT assay, the mitochondrial membrane potential was determined by fluorescence spectrophotometer, the expression levels of cy?tochrome C and Caspase-3 were quantified by Western blot and the transcription level of the Cyt C and Caspase-3 mRNA were determined by RT-PCR. The ability of invasion in each group was measured with Transwell assays. Results Com?pared with Nthy-ori 3-1, the mRNA transcription and protein expression levels of the Mfn2 was remarkably decreased, while the mRNA transcription and protein expression of the Drp1 was significantly increased in SW579 cells (P<0.01). Compared with control group, the cell survival rates and mitochondrial membrane potential of SW579 were decreased dramat?ically (P<0.01). The mRNA transcription and protein expression of the cytochrome C and Caspase-3 were increased dra?matically (P<0.01) and the capability of invasion was markedly decreased in all the Mdivi-1 groups in a dosage dependent manner compared with those in control groups (P<0.01). Conclusion Abnormal mitochondrial dynamics may be involved in thyroid squamous cell carcinoma SW579 cells;Mdivi-1 can inhibit the cell proliferation and invasion as well as induce apoptosis.

Objective Heart transplantation is an effective treatment of end-stage heart diseases and extending the time of donor heart preservation helps to make up for the shortage of donor hearts. This study was to investigate whether high-pressured mixed gas ( HPMG) of carbon monoxide and oxygen could prolong the time of donor heart preservation and its mechanisms. Methods Forty-eight C57BL/6 male mice aged 4-6 weeks were randomly divided in-to four groups of equal number:control ( the donor heart isolated but not transplanted) , immediate transplantation ( the donor heart transplanted right after isolated) , HTK-preservation ( the donor heart preserved in histidine-tryptophan-ketoglutarate solution for 24 hours after isolated, and HPMG preservation ( the donor heart preserved in an HPMG chamber with the oxygen partial pressure of 3200 hPa and carbon monoxide partial pressure of 800 hPa for 24 hours after isolated) .Another 36 recipient mice aged 6-8 weeks were randomly assigned to receive the donor heart immediately after harvested (n=12), preserved in HTK solution (n=12), or preserved in HPMG (n=12).At 2 hours after transplantation, the status of heart re-beating and cardiac function were compared among different groups of recipient mice.At 24 hours, tissues were taken from the transplanted hearts for examination of pathologic changes by HE stai-ning, detection of the apoptosis of cardiac cells by TUNEL, and determination of the expressions of microtubule-associated protein 1 light chain 3 -Ⅱ(LC3-Ⅱ) and B cell lymphoma/leukemia-2 (Bcl-2) by Western blot. Resul ts The re-beating rates of the imme-diately transplanted and HPMG-preserved hearts were significantly higher than that of the HTK-preserved ones (P<0.05).At 2 hours after transplantation, the cardiac function scores were 2.5 (2.0-2.9), 0.8 (0.5-1.0), and 4.5 (4.0-4.5) in the immediate implantation, HPMG-preservation and HTK-preservation groups respectively, with statistically significant differences between any two groups (P<0.05).The expressions of LC3-Ⅱand Bcl-2 were 2.06 ±0.29 and 0.87 ±0.18 in the HPMG-preserved heart recipients and 1.24 ±0.20 and 2.07 ±0.32 in the immediately transplanted heart recipients, both higher than 0.13 ±0.03 and 0.19 ±0.02 in the controls and 0.16 ±0.06 and 0.26 ±0.08 in the HTK-preserved heart recipients (P<0.05), the Bcl-2 higher in the HTK-pre-served heart recipients than in the controls (P<0.05), and the LC3-Ⅱ expression higher in the HPMG-preserved heart recipients than in the immediately transplanted heart recipients (P<0.05).HE staining showed that cell edema and inflammatory cell infiltration were more obvious in the HPMG-preserved heart recipients than in the controls and immediately transplanted heart recipients but less obvious than in the HTK-preserved heart recipients.The rate of cell apoptosis was dramatically increased in the HPMG-and HTK-pre-served heart recipients ([5.04 ±1.77]%and [26.72 ±5.23]%) in comparison with the controls ([1.08 ±0.56]%) (P<0.01) and immediately transplanted heart recipients ([2.13 ±1.71]%) (P<0.01) but decreased in the HPMG as compared with the HTK-preserved heart recipients (P<0.01). Conclusion High-pressured mixed gas preservation can reduce cold ischemia-reperfu-sion injury of the donor heart, which may be associated with its promotion of autophagy, provision of energy to cells, and apoptosis of cardiocytes in the donor heart.

Objective: To assess the effect of coronary collateral circulation (CCC) on myocardial viabilityin patients with chronic total occlusion of left anterior descending (LAD) artery. Methods: A total of 101 consecutive patients with confirmed diagnosis of total LAD occlusion in our hospital were enrolled. Rest 99mTc-MIBISPECT myocardial perfusion and 18F-FDG PET were performed, in addition all patients received coronary angiography (CAG) at 3 months front and back. Both images were reconstructed in the same machine and QPS software was used to obtain the summed rest score (SRS), abnormal resting total perfusion defect (TPD), viable and non-viable myocardium, LVEDV, LVESV and LVEF in relevant patients. Based on CAG result, the patients were divided into 2 groups: CCC group, n=39 and No CCC group, n=62; according to existing old myocardial infarctionand location of LAD occlusion, the patients were further divided into 4 subgroups. The above parameters were compared among different groups. Results: There were 86 male and 15 female patients with the mean age at (59.92±11.43) years. Relevant parameters in CCC group and No CCC groupwere as in SRS: (21.23±9.68) vs (28.56±8.76), TPD: (30.03±13.69) %vs (40.37±12.50) %, viable myocardium: (21.77±13.12) % vs (13.66±9.23) %, non-viable myocardium (8.28±8.58) %vs (27.40±12.97) %, all P<0.05; in LVEDV: (109.82±30.01) ml vs (173.71±57.69) ml, LVESV: (62.82±22.39) ml vs (122.53±51.66) ml, LVEF: (43.85±8.46) % vs (31.03±8.30) %, all P<0.05. Conclusion: Our preliminary study found that CCC could maintain left ventricular rest perfusion, myocardial viability and protect cardiac function in patients with chronic total LAD occlusion.

Objective To analyze if there are membrane estrogen receptors(ER)in endometrial carcinoma and if there is some relationship between membrane ER and nuclear ER.Methods The cell membrane and total cell ER?and ER?expressions of high and moderate differentiation endometrial carcinoma cells(Ishikawa and HEC-1A cells)were analyzed.Intermittent immunofluorescence dyeing and fluorescent microscopy were carried out with the ceils treated with polyformaldehyde and Triton X-100. Intermittent immunofluorescence dyeing and flow cytometry were carried out with the live cells and the cells treated with Triton X-100 respectively.Results There were fluorescences on the membrane of the Ishikawa and HEC-1A cells which were treated with polyformaldehyde.When the cells were treated with Triton X- 100,the fluorescences were also seen inside the cells.The fluorescence intensity of ER?and ER?in Ishikawa cell membrane(1.09?0.21,1.27?0.33)was stronger than the control,but there were no significant differences(P>0.05).When treated with Triton X-100,the total cell fluorescence intensity of ER?and ER?in Ishikawa cell(4.21?0.34,4.69?1.96)was stronger than the membrane(P<0.05). The ER?and ER?fluorescence intensity of HEC-1A cell membrane(1.58?0.13,1.49?0.04)were stronger than the control(P<0.05).The fluorescence intensity of ER?and ER?of the HEC-1A cell (2.34?0.33,2.52?0.15)was stronger than the membrane also(P<0.05).The membrane ER?fluorescence intensity of Ishikawa was lower than HEC-1A(P=0.028).But the total cell ER?fluorescence intensity of Ishikawa was higher than HEC-1A(P=0.002).Conclusions There are membrane ER on endometrial carcinoma cells Ishikawa and HEC-1A.The membrane ER must have some similarity to the nuclear receptor.There is no direct correlation between the quantity of the membrane ER and nuclear ER.
