Objective: To investigate the effect of interleukin-8 (IL-8) on survival and apoptosis of hypoxic human umbilical vein endothelial cells (HUVECs) with its mechanisms.
Methods: Hypoxic HUVECs were induced by CoCl2. HUVECs were cultured with different concentrations of CoCl2 or IL-8 and the survival rates of HUVECs were examined. Normal or hypoxic HUVECs were incubated with IL-8 or simultaneously incubated with anti-IL-8 or Akt inhibitor LY294002 for 48h. The HUVECs survival rate was detected by MTT method, apoptosis rate was measured by Annexin V-FITC/PI method, the protein expressions of Caspase-3, phosphorylated Akt (pAkt) and GSK-3βser9 (pGSK-3βser9) were evaluated by Western blot analysis.
Results: By 12 h incubation with low concentration of CoCl2 (50, 100 μmol/L), HUVECs proliferation were improved, P<0.01; while by 24h and 48 h incubation with high concentration of CoCl2 (200, 400 μmol/L) HUVECs survival were decreased. By 48h and 72h incubation with IL-8 at (10, 50, 100 ng/ml), the hypoxia induced cell apoptosis was decreased and the survival was increased,P<0.01. IL-8 at 10 ng/ml may obviously inhibit the normal and hypoxic HUVECs apoptosis, down-regulate caspase-3 and up-regulate pAkt and pGSK-3βser9 expressions in HUVECs,P<0.01, while the above effects could be reversed by LY294002 and anti-IL-8,P<0.01.
Conclusion: IL-8 could down-regulate caspase-3 and up-regulate pAkt and pGSK-3βser9 expressions in HUVECs and therefore, inhibit the apoptosis and improve the survival of hypoxic HUVECs.

AIM To investigate the effect of DO C(deoxycholic acid) on the absorption of INS-PLA-NP[insulin-loaded poly(lactic acid) nanoparticles] in different sites of gastrointestinal tracts. METHODS After INS-PLA-NP that contained or did not contain DOC was adminitered to different sites in gastrointestianl tracts(stomach, small intestine and colon)of normal rats, the hypoglycemic effect was observed. RESULTS The hypoglycemic effect did not exist after intragastric administration of INS-PLA-NP whether or not DOC was added. The alleviatory hypoglycemic effect was evident after intraintestinal absorption of INS-PLA-NP. After DOC was added, the absorption of INS-PLA-NP was accelerated obviously and the hypoglycemic effect was strengthened significantly. Glucose levels hardly changed after INS-PLA-NP was administered to colon. With the use of DOC, a little hypoglycemic effect appeared. CONCLUSIONS The absorption of INS-PLA-NP in small intestine was accelerated and enhanced by DOC. DOC could be used as absorption enhancer of INS-NP in the future.

Objective To investigate the effect of progressive neurological deterioration ( PND) of cerebral watershed infarction on early prognosis. Methods The consecutive patients with cerebral watershed infarction admitted in the Department of Neurology,Jinling Hospital,Nanjing University School of Medicine and their cerebral watershed infarctions confirmed by the imaging examination from March 2009 to March 2014 were enrolled. The clinical features, laboratory indicators and imaging features of internal watershed infarction,cortical-type watershed infarction,and mixed watershed infarction were identified and analyzed. The National Institutes of Health Stroke Scale was used to score neurological deficit. The modified Rankin scale ( mRS) was used to score the prognosis of patients. Single factor analysis was used to compare the differences between the groups. At the same time,the correlation between PND and poor prognosis of cerebral watershed infarction at day 90 was analyzed by multivariable Logistic regression analysis. Results A total of 89 patients with cerebral watershed infarction were enrolled,including 43 cortical-type watershed infarctions,36 internal watershed infarctions, and 10 mixed watershed infarctions. Single factor analysis indicated that the incidences of PND of internal watershed infarction and mixed watershed infarction were significantly higher than the cortical-type watershed infarction (36. 1% [n=13],50. 0% [n=5], and 16. 3% [n=7],respectively;P=0. 018). At day 90,28 patients had poor prognosis,and mRS was (3.4±1. 0) scores at day 90. There was significant difference in the types of infarction between the patients with poor prognosis and patients with good prognosis (P<0. 05). In patients with poor prognosis, most of them were internal watershed infarctions,accounting for 50. 0% (14/28),while in patients with good prognosis,most of them were cortical-type watershed infarctions(57. 4% [35/61]). The incidence of PND in patients with poor prognosis was significantly higher than that in patients with good prognosis (57.1% [16/28] vs. 14. 8% [9/61];P<0. 05). The result of multivariate Logistic regression analysis showed that after adjustment for confounding factor, PND was independently associated with the poor prognosis of cerebral watershed infarction at day 90 (OR 6. 969,95%CI 2. 451-19. 869;P<0. 01). Conclusion Compared with the cortical-type watershed infarction, the patients with internal watershed infarction is more prone to have PND, and PND is independently correlate with the poor prognosis at day 90.
