Journal of Chinese Physician.2013;15(8):1013-1017. doi:10.3760/cma.j.issn.1008-1372.2013.08.002

Objective To investigate the signal mechanism of protein kinase C alpha(PKC-α)participated in enhanced expression of type Ⅰ inositol 1,4,5-trisphophate receptors (IP3 RI) induced by tumor necrosis factor alpha(TNFα),in order to delineate the mechanisms of decreased glomerular filtration rate (GFR) in hepatorenal syndrome caused by TNFα.Methods The glomerular mesangial cells (GMCs)line from rats was chosen as experimental material.GMCs were divided into control (D),TNFα-2 h,TNFα-4 h,TNFα-8 h,and TNFα-24 h groups.Moreover,another two groups were sanflngol-8h (S),TNFα + Sanfingol-8h(TS)groups.The effect of TNFα on the expression of IP3RI was detected by immunocytochemical staining,Western blotting,teal time-polymerase chain reaction (PCR) assays.Results Immunocytochemical staining demonstrated that IP3 RI was mainly distributed in cytoplasm of GMCs.Enhanced positive staining was determined in all TNFα-treated groups,especially in TNFα-8 h group.Western blotting demonstrated that the expression of IP3RI protein was significantly higher in TNFα-4 h,TNFα-8h and TNFα-24 h groups than control group(4 h:1.82 ± 0.63 ; 8 h:2.95 ± 0.66 ; 24 h:2.48 ± 0.72 ; D:1 ±0.02 ; F =9.24,P ＜ 0.05).The expression of IP3 RI protein was the highest in TNFα-8 h and TNFα-24 h groups(P ＜0.05).No difference was found among S,TS,and control groups(S:1.39 ±0.65; TS:1.35± 0.37 ; P ＞ 0.05).Real time-PCR found the expression of IP3 RImRNA was significantly higher in all TNFα-treated groups than control group(2 h:3.35 ± 1.97; 4 h:3.16 ± 1.35; 8 h:3.70 ± 1.76; 24 h:4.49±1.70; D:1 ±0.01; F =6.167,P ＜0.05).No difference was found among all TNFα-treated groups(P ＞0.05).No difference was found among S,TS,and control groups(S:1.53 ±0.79; TS:1.32 ± 0.38 ; P ＞ 0.05).Conclusions IP3 RI was mainly distributed in cytoplasm of GMCs.TNFa could enhance the expression of IP3 RI protein and IP3 RI mRNA,which could be blocked by sanfingol,a PKCα inhibitor.It might be an important signal in the mechanisms of GFR decrease caused by TNFα in hepatorenal syndrome.

Journal of Chinese Physician.2013;15(8):1032-1036. doi:10.3760/cma.j.issn.1008-1372.2013.08.007

Objective To investigate the beneficial effects and possible mechanisms of intrathecal injection of dexmedetomidine (DEX) in protection of spinal cord ischemia-reperfusion injury.Methods Spinal cord ischemia-reperfusion injury was induced in rabbits by infrarenal aortic occlusion for 30 minutes.Twenty-four rabbits were randomly divided into four groups:sham group,I/R group,DEX group (1 μg/kg dexmedetomidine by intrathecal injection),DEX + ATIP group (1 μg/kg dexmedetomidine and 0.5 μg/kg atipamezole (ATIP) by intrathecal injection).Physiological indices were assessed and motor neurons in the ventral gray matter were counted by histological examination.The expression of total extracellular signal-related kinase (t-ERK),phospho-extracellular signal-related kinase (p-ERK),and caspase 3 were assessed by Western blotting and real-time polymerase chain reaction (RT-PCR).The water content in spines was also measured.Results Intrathecal injection of dexmedetomidine minimized the neuromotor dysfunction and histopathological deficits(F =14.32,P ＜ 0.05) and attenuated the influences of peroxidation at 24 hours after spinal cord ischemia-reperfusion injury.The physical indices during experiment were comparable among all groups.In addition,intrathecal injection of dexmedetomidine reduced the excessive expression of caspase 3 mediated by ERK signal pathway(F =15.45,P ＜ 0.05).Conclusions Pre-emptive intrathecal injection of dexmedetomidine produced beneficial effects on spinal cord after spinal cord ischemia-reperfusion injury in a rabbit model of transient aortic occlusion.This beneficial effect was partly attributed to the inhibition of caspase 3 mediated by ERK signal pathway,which represents a potential therapeutic approach to mitigate spinal cord injury after aortic occlusion.
