Objective To investigate the effects of soluble endoglin(sEng)on nitric oxide (NO)production and endothelial nitric oxide synthase(eNOS)phosphorylation in cultured human umbilical vein endothelial cells.Methods Human umbilical vein endothelial cells within 3 passages seeded in culture plates of 96 wells,were stimulated by total culture medium(control group)or sEng (1,10 and 100 μg/L)respectively.Cells and medium were collected after cells were cultured for 6,12 and 24 hours respectively.The concentration of the metabolites of NO in each group was measured by nitrate reductase method.The expression of eNOS and eNOS-Ser(p)1177 were detected by Western blot.The expression of eNOS mRNA in each group was detected by real-time fluorescence reverse transcription-polymerase chain reaction.Analysis of variance,LSD method and pearson correlation were used to compare the difference between groups.Results(1)The concentration of the metabolites of NO in 1,10 and 100μg/L sEng groups was(59.25±1.63),(41.08±2.71)and (30.38±1.63)μmol/L respectively after cultured for 6 hours;(54.98±3.34),(35.00±8.60)and (19.82±3.75)μmol/L for 12 hours; and(46.14±4.93),(30.24±2.08)and(12.78±5.01)μmol/L for 24 hours.There was no significant changes in control group with time going by(F=2.30,P=0.14).The concentration of the metabolites of NO was significantly lower in sEng group,and which had negative correlation with culture time(r=-0.98,P＜0.05)and dose(r=-0.88,P＜0.05).(2)The expression of eNOS in 1,10,100 μg/L sEng groups was 0.71 ± 0.00,0.47 ± 0.00 and 0.32±0.00 after cultured for 6 hours; 0.58±0.00,0.42±0.00 and 0.25±0.00 for 12 hours; and 0.49±0.00,0.33±0.00 and 0.18±0.00 for 24 hours.While the expression of eNOS and eNOS-Ser (p)1177/eNOS had no significant changes in control group with time going by(F=3.59 and 0.37,P=0.09 and 0.80).The expression of eNOS protein and eNOS-Ser(p)1177 decreased significantly in sEng groups,which had negative correlation with culture time(r=0.98 and-0.96,P＜0.05)and dose(r=-0.76 and-0.79,P＜0.05).(3)The expression of eNOS mRNA decreased significantly in sEng groups.Which also had negative correlation with culture time(r=-0.51,P＜0.05)and dose(r=-0.82,P＜0.05).Conclusions sEng might inhibit eNOS activity by blocking 1177 Ser phosphorylation to decrease NO production.

Objective To investigate the effects of CORM-2 via p38 mitogeu-activated protein kinase (p38MAPK) signaling pathway on the expression of the mitochondrial fission protein 1 (Fisl) in lipopolysaccharide (LPS)-induced mouse pulmonary macrophages.Methods The rat subculture alveolar macrophages were seeded on 96 well plates with 2 × 105/ml densities.After 24 hours of culture,it was divided into 4 groups by random number table method:normal control group (group C),group LPS (group L),CO releasing agent CORM-2 + LPS group (group LC),p38MAPK inhibitor SB203580 + CORM-2 + LPS group (group LCS).When the cells were incubated for 24 hours,the mitochondrial MDA content and SOD activity were determined by ELISA kit,the levels of HO-1、mitochondrial fission protein Fis1 and p38 were determined by Western blot,the expressions of HO-1 and mitochondrial fission protein Fis1 were detected by RT-PCR.Results Compared with the C group,the levels of MDA [(2.43 ±0.12) vs.(3.59 ±0.07)],HO-1 [(1.31±0.27) vs.(1.65±0.41)],Fis1 [(1.27±0.23) vs.(1.65±0.41)] andp38 [(1.01 ±0.24) vs.(1.36 ±0.17)] in group L were increased,and the activity of SOD [(81.7 ± 1.62) vs.(54.7 ± 1.62)] was decreased (P ＜ 0.05);Compared with the group L,the MDA content [(3.59 ± 0.07) vs.(3.08 ±0.52)] and the level of Fis1 [(2.01 ±0.35) vs.(1.48 ±0.39)] in group LC were down-regulated,and the levels of SOD [(54.7 ± 1.62) vs.(67.4 ± 1.32)]、and the expressions of HO-1 [(1.65±0.41)vs.(2.25±0.18)] andp38 [(1.36±0.17) vs.(1.78±0.23)] wereup-regulated (P ＜0.05).Compared with the group LC,the MDA content [(3.08 ±0.52) vs.(4.16 ±0.19)] and the expression of Fis1 [(1.48 ±0.39) vs.(1.96 ±0.31)] in group LCS were increased,and the level of SOD [(67.4±1.32)vs.(45.9±1.52)]、and the expressions of HO-1 [(2.25±0.18)vs.(1.78± 0.19)] and p38 [(1.78 ±0.23) vs.(1.12 ±0.29)] were decreased (P ＜0.05).Conclusions HO-1/CO system inhibits the expression of Fis1 in LPS-induced lung macrophages,which may be regulated by p38MAPK signaling pathway.

AIM:To explore the effect of recombinamt rat CC16 protein (rCC16) on LPS-induced expression of tumor necrosis factor-alpha (TNF-α), interleukin-6 (IL-6) and IL-8 in the rat tracheal epithelial (RTE) cells. METHODS:The RTE cells were incubated with rCC16 at concentrations of 0.5, 1.0 and 2.0 mg/L in serum-free media for 2 h prior to LPS (0.1 mg/L) treatment for further 24 h.The cells were harvested for assessing the mRNA levels of TNF-α, IL-6 and IL-8 by RT-qPCR.The cell culture supernatants were collected for analyzing the protein levels of TNF -α, IL-6 and IL-8 by ELISA.In addition, the nuclear translocation of nuclear factor-κB (NF-κB) p65 was tested by Western blot.RESULTS:rCC16 inhibited LPS-induced IL-6 and IL-8 expression at both mRNA and protein levels in the RTE cells in a concentration-dependent (0~2 mg/L) manner, as demonstrated by RT-qPCR and ELISA.However, no concentra-tion-dependent manner between the dose of rCC 16 and TNF-αexpression was observed , and rCC16 inhibited LPS-induced TNF-αexpression at lower concentration (0.5 mg/L).rCC16 concentration-dependently inhibited the effects of LPS on the level of nuclear translocation of NF-κB p65.CONCLUSION:rCC16 suppresses LPS-mediated TNF-α, IL-6 and IL-8 pro-duction through inactivation of NF-κB activity in RTE cells .

Objective To investigate the awaken effect of naloxon on dexmedetomidine anesthetized mice and its mechanism. Methods Thirty Kunming mice of clean grade were randomly divided into 3 groups which included NAL group (Naloxon group), ATI group(Atipamezole group)and NS group (Normal Saline group). All groups were given dexme?detomidine 1 mg·kg-1 intraperitoneally. Naloxon 2 mg·kg-1, atipamezole 2 mg·kg-1 and normal saline 10 mL·kg-1 were ran?domly given intraperitoneally to the NAL, ATI and NS group respectively 90 minutes after dexmedetomidine administration. At timepoints prior to dexmedetomidine administration and 5, 15, 30, 60, 90, 95, 105, 120, 180 minutes after it, the sedative and analgesic effects besides recovery time (based on restore of righting reflex loss) were assessed. Results Sedation and analgesia effects became apparent within 5 minutes, and peaked at approximately 60 minutes then spontaneously recovered at 180 minutes after injection of dexmedetomidine. The sedative and analgesic effects were reduced in both ATI and NAL groups. Compared with ATI group, the sedation scores were higher at 95, 105 and 120 minutes after dexmedetomidine admin?istration than those in NAL group (P<0.05) but the scores were not statistically significant at 180 minutes between these two groups. Compared with NS group, the sedation scores were lower at time points of 95, 105, 120 and 180 minutes than those in NAL group (P>0.05). The analgesic scores were not statistically significant at time points of 95, 105, 120 and 180 min?utes between NAL group and ATI group, but they were lower in NAL group compared with NS group at timepoints of 95, 105 and 120 minutes (P>0.05). The recovery time in ATI and NAL group were shorter than that in NS group (F=1 793.368, P<0.05), but it showed no statistical difference between ATI group and NAL group (P>0.05). Conclusion Naloxone had a certain awaken effect on dexmedetomidine anesthetized mice.
