Objective To investigate the effect of penehyclidine (PHCD) pretreatment on Toll-like receptor 4 (TLR4) mRNA expression in the lung following acute lung injury (ALI) induced by hemorrhagic shock in rats. Methods Forty healthy SD rats of both sexes weighing 200-250 g were randomly divided into 5 groups( n = 8 each): group Ⅰ sham operation (group S); group Ⅱ ALI (group ALI); group Ⅲ, Ⅴ, PHCD 0.3,1.0, 3.0 mg/kg were given iv respectively at 30 min before hemorrhagic shock (P1-3). Hemorrhagic shock was induced by exsanguinations. MAP was maintained at 35-45 mm Hg for 60 min. The animals were killed at 4 h after resuscitation. Their lungs were removed for microscopic examination, W/D lung weight ratio and determination of TLR4 mRNA expression in the lung tissue (by RT-PCR). NF-κB p65 protein expression in the lung tissue was determined (by immuno-histochemical staining). Results Hemorrhagic shock significantly increased TLR4 mRNA and NF-κB p65 protein expression in the lung tissue and W/D lung weight ratio. Pretreatment with PHCD 1.0 or 3.0 mg/kg significantly inhibited hemorrhagic shock-induced increase in TLR4 mRNA and NF-κB p65 protein expression in the lung and W/D lung weight ratio. The lung injury was significantly ameliorated in group P2,3 as compared to group ALI. Conclusion PHCD pretreatment can attenuate ALI induced by hemorrhagic shock through down-regulation of TLR4 mRNA expression and decreasing NF-κB activity in the lung.

The transesterification reaction conditions of lard with methyl acetate with combined use of immobilized lipases as catalysts were conducted. Initially, according to single factorial experiments, the studies on Lipozyme TL IM and Novozym 435 respectively catalyzed transesterification of lard showed that the optimal parameters of transesterification reaction were: the molar ratio of methyl acetate to oil of 14∶1, 40% enzyme added based on oil weight, temperature 50℃. Combined use of Lipozyme TL IM and Novozym 435 was proposed further to improve the catalytic performance by the response surface method (RSM). Herein, a 5-level-3-factor central composite rotated design was employed to evaluate the effects of lipase loading, the proportion of the two lipases and amount of methyl acetate. The optimum conditions were as followings: 40% lipase loading based on oil weight, 50%/50% the proportion of lipases (Novozym 435/Lipozyme TL IM), and the molar ratio of methyl acetate to oil of 14∶1. And under the optimal conditions, the highest biodiesel yield of 97.6% could be attained, which was higher than the biodiesel yield with each single one of the two lipases. The results suggested that the technics of combined use of certain immobilized lipases catalyzed transesterification reaction of lard for biodiesel production with methyl acetate as the acyl acceptor could raise the FAME yield and save the production cost.

Objective To compare the effect of three types of lipid emulsions on the IL-1βand IL-6 expressions in acute lung injury induced by lipopolysaccharide (LPS) in rats. Methods One hundred young SD rats were divided into control,LPS,ω-6,ω-9 andω-3 group. Age 29 days, the control group were intravenously injected with saline,ω-6 group injected lipid emu-sion (C14-24),ω-9 group injected long chain fat emusion,ω-3 group injected fish oil fat emusion. Then the control group fol-lowed by intratracheal instillation of saline, and the reamining four groups were sprayed with LPS. Pathologic changes in lung tissue section were observed. The expression levels of IL-1βmRNA and IL-6 mRNA were determined by RT-PCR,and the con-centrations of IL-1βand IL-6 in bronchoalveolar lavage fluid (BALF) were measured by enzyme-linked immune-specific assay. Results Infiltration and bleeding were observed in lung tissue under light microscopy in ALI rats. The lung indexes and patho-logical scores of ALI model groups were significantly higher than those of control group (P<0.005). The expressions of IL-1βand IL-6 mRNA in groupsω-9 andω-3 were significantly higher than those in groups LPS andω-6 (P<0.005). The levels of IL-1βand IL-6 in BALF in groupsω-9 andω-3 were significantly higher than those in groups LPS andω-6 (P<0.005). There was no significant difference (P>0.005) of the expressions of IL-1βand IL-6 mRNA betweenω-9 andω-3 group. Conclusions ω-6 PUFAs can accentuate inflammation by up-regulating the levels of IL-1βand IL-6 whileω-9 PUFAs andω-3 PUFAs can relieve inflammation by down-regulating the levels of IL-1βand IL-6.
