Objective To investigate the effects of etomidate preconditioning on the expression of procaspase-3, caspase-9 p35 and caspase-8 p20 in HL-60 cells. Methods HL-60 cells were purchased from Shanghai life science institute and cultured in RPMI-1640 culture medium at 37℃ in 5% CO2 incubator. The cells were randomy divided into 3 groups ( n = 3 each): control group (group C), etomidate group (group E) and etomidate preconditioning group (group EP). In group E, the cells were exposed to 500 μmol/L etomidate and incubated for 24 h. In group EP, the cells were exposed to 1μmol/L etomidate for 1 h and was allowed to recover for4 h after etomidate washout, then etomidate 500μmol/L was added and the cells were incubated for 24 h. The expression of procaspase-3, caspase-9 p35 and caspase-8 p20 was determined using Western blot. Results The procaspase-3 expression was significantly down-regulated, while the expression of caspase-9 p35 and caspase-8 p20 was up-regulated ingroup E and EP as compared with group C ( P ＜ 0.05). The procaspase-3 expression was up-regulated,while the expression of caspase-9 p35 and caspase-8 p20 was down-regulated in group EP as compared with group E ( P ＜ 0.05). Conclusion Etomidate preconditiong can inhibit etomidate-induced down-regulation of procaspase3 expression and up-regulation of caspase-9 p35 and caspase-8 p20 expression, resulting in suppression of HL-60 cell apoptosis induced by etomidate.

The anaerobic granular sludge from an Internal Circulation (IC) reactor of a paper mill wastewater treatment plant were seeded in an Anammox upflow anaerobic sludge blanket reactor. After 185 days operation, the reactor was finally started up by increasing the influent ammonium and nitrite concentrations to 224 mg/L and 255 mg/L, respectively, with volumetric nitrogen removal rate increasing to 3.76 kg/(m3·d). The physicochemical characteristics of the cultivated Anammox granules were observed by scanning electron microscope, transmission electron microscope and Fourier Transform infrared spectroscopy (FTIR). Results suggested that during the start-up course, the granular sludge initially disintegrated and then re-aggregated. FTIR spectra results revealed that the Anammox granular sludge contained abundant functional groups, indicating that it may also possess good adsorption properties. The ecological structure of the granular sludge, analyzed by the metagenomic sequencing methods, suggested that the relative abundance of the dominant bacterial community in the seeding sludge, i.e., Proteobacteria, Firmicutes, Bacteroidetes, significantly reduced, while Planctomycetes which contains anaerobic ammonium oxidation bacteria remarkably increased from 1.59% to 23.24% in the Anammox granules.

Objective To explore the effect of mesenteric lymphatic ligation on liver injury induced by severe acute pancreatitis. Methods 54 SD rats are randomly divided into sham-operation group (A), severe acute pancreatitis group (B) and severe acute pancreatitis and ligation group (C). Liver tissues were collected from each rat in 6, 12, and 24 h after ligation. Pathological changes in liver tissues were observed by haematoxylin and eosin staining. Levels of serum glutamic-pyruvic transaminase and glutamic oxalacetic transaminase were detected. Levels of TNF-α and IL-1 in liver homogenate were examined by enzyme linked immunosorbent assay. Results Under light microscopic examination, neutrophils and inflammatory exudate in hepatic lobule was increased as time prolonged in group B. Inflammation was reduced in group C as compared with group B.Levels of serum glutamic-pyruvic transaminase and glutamic oxalacetic transaminase were more significantly increased in groups B and C than in group A (P<0.05);while they were more significantly decreased in group C than in group B. Levels of TNF-αand IL-1 in liver homogenate were significantly increased in group B as compared with group A (P < 0.05); whereas they were more significantly decreased in group C than in group B at 24 h (P < 0.05). Conclusions Mesenteric lymphatic ligation can reduce liver injury in severe acute pancreatitis. Mesenteric lymphatic fluids may play an important role in severe acute pancreatitis.

Objective To evaluate 1-week and 1-year outcomes of carotid artery stenting (CAS)using cerebral perfusion CT(PCT). Methods The clinical database of 20 patients with unilateral carotid artery stenosis( ≥60% ) who underwent CAS were retrospectively reviewed. Relative cerebral blood volume (rCBV), relative cerebral blood flow(rCBF) and relative mean transit time( rMTT) were measured by using cerebral PCT within one week before CAS and at one week and at one year after CAS. Cerebral MRI was performed within one week before CAS. The noncontrast CT was performed within one week before CAS and immediately after CAS. The arteriography was performed at one year after CAS. The variance analysis was performed to determine whether there were significant differences of rCBV, rCBF, rMTT in anterior cerebral artery area( ACA area), middle cerebral artery area( MCA area), posterior cerebral artery area( PCA area),basal ganglia area, front and back cortical watershed area( CWS area) and internal watershed area( IWS area) among the different time points. Results In the three measures, there was no significant difference of rCBV in all areas among the three time points( P ＞ 0. 05 ) , and there was no significant difference of rCBF and rMTT in PCA area( P ＞ 0. 05 ), but there were significant differences of rCBF and rMTT in all other areas among the three time ponits(P ＜0. 01). In one week before CAS, at one week and at one year after CAS, rCBF of 20 patients is 0. 86 ±0. 06, 0. 95 ±0. 04, 0. 98 ±0. 07 in ACA area, 0. 81 ±0. 04, 1.06 ±0. 04, 1.03 ±0.07 in MCA area, 0. 84 ±0. 06, 0. 97 ±0. 04, 0. 96 ±0. 04 in basal ganglia, 0. 78 ±0. 03,0. 97 ±0. 03, 0. 96 ±0. 02 in front CWS area, 0. 77 ±0. 03, 1.00 ±0. 02, 0. 98 ±0. 03 in back CWS area,and 0. 80 ± 0. 04, 0. 94 ± 0. 03, 0. 93 ± 0. 04 in IWS area ( F = 18. 95, 146. 41,63.03,540. 85,415.97,164.19, P＜0. 01). rMTT is 1.17 ±0.05, 1.04±0.04, 1.01 ±0.06 in ACA area, 1.41±0.06, 1.08±0.04, 1.07±0.04 in MCA area, 1.20±0.06, 1.06±0.04, 1.05±0.04 in basal ganglia, 1.41 ±0.05,1.10 ±0. 05, 1.09 ±0. 04 in front CWS area, 1.43 ±0. 10, 1.07 ±0. 06, 1.08 ±0. 06 in back CWS area,1.29±0.10, 1.09 ±0.05, 1.11 ±0.07 in IWS area (F=51.74, 248. 89, 70.08, 381.68, 288.94,41.53, P ＜0. 01 ). There were significant differences of rCBF and rMTT between those measured one week before CAS and one week or one year after CAS ( P ＜ 0. 01 ), but there were no significant differences of rCBF or rMTT in any area measured between those at 1 week after CAS and those measured at 1 year after CAS(P＞0.05). Conclusions Hemodynamic outcome at one year after CAS is good in the absence of contralateral carotid artery steno-occlusive disease. In addition, the coherence of results between 1-week and 1-year indicates that the outcome of one week after CAS could predict long-term hemodynamic outcome.
