AIM: To study the synergistic effects of calmodulin (CAM) antagonist O-4-ethoxyl-butyl-berbamine (EBB) and pegylated liposomal doxorubicin (PLD) on hepatoma-22 (H22) in vivo. METHODS: Hepatoma model was established in 50 Balb/c mice by inoculating H22 cells (2.5×10^6) subcutaneously into the right backs of the mice. These mice were divided into 5 groups, and treated with saline only, PLD only, doxorubicin (Dox) only, PLD plus EBB and Dox plus EBB, respectively. In the treatment groups, mice were given 5 intravenous of PLD or Dox on days 0, 3, 6, 9 and 12. The first dosage of PLD or Dox was 4.5 mg/kg, the other 4 injections was 1 mg/kg. EBB (5 mg/kg) was coadministered with PLD or Dox in the corresponding groups. The effect of drugs on the life spans of hepatoma-bearing mice and tumor response to the drugs were recorded. Dox levels in the hepatoma cells were measured by a fluorescence assay. Light microscopy was performed to determine the histopathological changes in the major organs of these tumor-bearing mice. The MTT method was used to analyze the effect of Dox or PLD alone, Dox in combination with EBB, or PLD in combination with EBB on the growth of H22 cells in an in vitro experiment. RESULTS: EBB (5 mg/kg) significantly augmented the antitumor activity of Dox or PLD, remarkably prolonged the median survival time. The median survival time was 18.2 d for control group, but 89.2 d for PLD+EBB group and 70.1 d for Dox+EBB group, respectively. However, Dox alone did not show any remarkable antitumor activity, and the median survival time was just 29.7 d. Addition of EBB to Dox or PLD significantly increased the level of Dox in H22 cells in vivo. Moreover, EBB diminished liver toxicity of Dox and PLD. In vitro, EBB reduced the IC50 value of Dox or PLD on H22cells from 0.050±0.006 mg/L and 0.054±0.004 mg/L to 0.012±0.002 mg/L and 0.013±0.002 mg/L, respectively (P<0.01). CONCLUSION: EBB and liposomization could improve the therapeutic efficacy of Dox in liver cancer, w

Objective Acute kidney injury （AKI） frequently occurs after catheter-based interventional procedures and increases mortality. However, the implications of AKI before thoracic endovascular aneurysm repair （TEVAR） of type B acute aortic dissection （AAD） remain unclear. This study evaluated the incidence, predictors, and in-hospital outcomes of AKI before TEVAR in patients with type B AAD. Methods Between 2009 and 2013, 76 patients were retrospectively evaluated who received TEVAR for type B AAD within 36 h from symptom onset. The patients were classified into no-AKI vs. AKI groups, and the severity of AKI was further staged according to kidney disease： im- proving global outcomes criteria before TEVAR. Results The incidence of preoperative AKI was 36.8%. In-hospital complications was significantly higher in patients with preoperative AKI compared with no-AKI （50.0% vs. 4.2%, respectively; P 〈 0.001）, including acute renal failure （21.4% vs. O, respectively; P 〈 0.001）, and they increased with severity of AKI （P 〈 0.001）. The maximum levels of body tem- perature and white blood cell count were significantly related to maximum serum creatinine level before TEVAR. Multivariate analysis showed that systolic blood pressure on admission （OR： 1.023; 95% CI： 1.003-1.044; P ： 0.0238） and bilateral renal artery involvement （OR： 19.076; 95% CI： 1.914 190.164; P = 0.0120） were strong predictors of preoperative AKI. Conclusions Preoperative AKI frequently occurred in patients with type B AAD, and correlated with higher in-hospital complications and enhanced inflammatory reaction. Systolic blood pressure on admission and bilateral renal artery involvement were major risk factors for AKI before TEVAR.

Background Acute kidney injury （AKI） is common after surgery for acute aortic dissection （AAD） and increases in-hospital and long-term mortality. However, few data exist on the clinical and prognostic relevance of early preoperative AKI in patients with type A AAD We aimed to determine the incidence and predictors of preoperative AKI and the impact of AKI on in-hospital outcomes in patients with type A AAD. Methods From May 2009 to June 2014, we retrospectively enrolled 178 patients admitted to our hospital within 48 h from symp- tom onset and receiving open surgery for type A AAD. The patients were divided into no AKI and AKI groups and staged with AKI severity according to the KDIGO criteria before surgery. Results AKI occurred in 41 patients （23.0%）. The incidence of in-hospital complications was significantly higher in patients with preoperative AKI compared to no AKI （41.5% vs. 9.5%, P 〈 0.001）, including renal infarction （7.3% vs. 0, P = 0.012）, and it increased with AKI severity （Ptrend〈 0.001）. Patients with AKI had higher in-hospital mortality compared with pa- tients without AKI, although no significant difference was found （14.6% vs. 5.1%, P = 0.079）. Multivariate analysis indicated that male gender, diastolic blood pressure on admission and bilateral renal artery involvement were independent predictors of preoperative AKI in patients with type A AAD. Conclusions Early AKI before surgery was common in patients with type A AAD, and was associated with increased in-hospital complications. Male gender, diastolic blood pressure on admission and bilateral renal artery involvement were major predictors for preoperative AKI.

The flight capacity of different ages and sexes of the sycamore lace bug, Corythucha ciliata, was studied at different temperatures using a flight mill system. The results of regression analysis showed a significant effect of temperature on flight distance (P=0.0082). Temperature did not influence flight duration (P=0.212) or flight speed (P=0.175). The mean flight distance (1 024 m) and mean flight duration were the greatest at 25.2°C. The age of C. ciliata had a significant influence on flight distance (P=0.0005), flight duration (P=0.0005) and flight speed (P=0.026). The 12-d-old adult had the greatest flight distance (887 m), duration (3 875 s) and speed (0.22 m s^–1). Flight distances and flight duration of females were significantly longer than that of males. However, the male had significantly greater flight speed than the female. The insect appears to be capable of long distance flights. The understanding of the optimal age and temperature for the flight of this insect through this study provides a foundation for better management of the insect in China.
