Objective To investigate the effect of tumor necrosis factor alpha ( TNF-?) in combination with Go6976 on murine liver cancer cells (H22). Method H22 cells were divided into two groups. Each group was further divided into four subgroups. Group 1 was treated with TNF-? 0, 20, 40, 60ng/ml. Group 2 was treated with TNF-? 0, 20, 40, 60 ng/ml and Go6976 (4.6 nmol/ml). The apoptotic rate, protein kinase C alpha (PKC-?) expression and phosphorylation-PKC-? (p-PKC-?) were detected by flow cytometer and Western blotting respectively in 4 h, 8 h and 16 h. Result Treated with TNF-? (0, 20, 40, 60 ng/ml) for 4 h, the apoptotic rates of H22 cells were 2. 44% ? 0. 31 % , 1. 80% ? 0. 32% , 2. 73% ?0. 14% and 3. 05% ?0. 78% respectively, with no change on the expression of PKC-? and p-PKC-?; For 8 h, the expressions of PKC-? and p-PKC-? in H22 cells were up-regulated with increasing concentration of TNF-?; When PKC-? was inhibited with Go6976 at the same time, the apoptotic rates of cells increased significantly, being 2. 90% ?0.39%, 7.76% ?0.35%, 11.43% ?1.05% and 12.96% ?2.44% , respectively. Moreover, PKC-? and p-PKC-? were down-regulated accordingly. When H22 cells were treated with TNF-? only or combined with Go6976 for 16 h, the result was similar to that of 8 h; The apoptotic rate dropped in the group in which PKC-? was inhibited by Go6976 with TNF-? at 60 ng/ml, but the proportion of necrotic cells increased. Conclusion TNF-? up-regulates the expression of PKC-? and p-PKC-? in H22 cells. Inhibiting the activity of PKC-? significantly enhances the toxicity of TNF-? to H22 cells.

Objective This retrospective study is to analyze and summarize the clinical features and therapeutic experience of the isolated abdominal aortic dissection(IAAD). Methods Totally 17 patients of IAAD, who were admitted to our hospital from January 2009 to January 2016, were included in this retrospective analysis. Five patients with obvious pain or abdominal aorta diameter of 30 mm accompanied with sub-renal anchorage area of 15 mm, underwent endovascular repair. In these 5 patients, 4 cases were subjected to bifurcated stent graft endovascular repair and 1 case received the aorta uni-iliac endovascular repair combined with femoral-femoral artery bypass treatment. Moreover, 2 patients with sub-renal anchorage area of less than 15 mm were subjected to surgical treatment. In these 2 patients, 1 case with obvious pain and abdominal aorta diameter of 30 mm underwent the abdominal aorta-right iliac artery bypass combined with femoral-femoral artery bypass, while the other case with abdominal aorta diameter of 30 mm but no pain received the abdominal aorta-bilateral iliac artery bypass. Furthermore, 8 patients with no obvious pain and abdominal aorta diameter of less than 30 mm received conservative medical treatment. In addition, there were 2 patients with obvious pain and abdominal aorta diameter of 30 mm suffering from sudden death during the surgical preparation. Important complications of these patients during hospitalization and follow-up period were recorded, analyzed, and compared. Results For the 5 patients undergoing endovascular repair, the averaged hospitalization duration was(15.4 ± 2.9)d, one of whom died during hospitalization. There were 3 cases with follow-up period of ≥ 12 months, and 1 case reported left iliac branch occlusion. For the 2 patients subjected to surgical treatment, the follow-up period was less than 12 months, and no serious complications occurred during hospitalization or follow-up period. For the 8 patients receiving conservative medical treatment, the averaged hospitalization duration was(11.1±5.2)d. There were 4 cases with follow-up period of ≥ 12 months, and no serious complications occurred during hospitalization or follow-up period. Conclusions Endo or open surgical treatment is recommended for patients with isolated abdominal aortic dissection with obvious pain or abdominal aortic diameter of 30 mm. For the patients with no pain and abdominal aortic diameter of less than 30 mm, conservative medical treatment is recommended.
