Objective To study the effect of pentoxifylline (PTX) on acute lung injury (ALI) in murine sepsis induced by intra abdominal infection. Methods Wistar rats were subjected to sepsis caused by cecal ligation and puncture (CLP), and animals were randomly divided into normal controls ( n =6), sepsis group ( n =18), and PTX treated group ( n =18). Pulmonary biopterin, nitric oxide (NO) levels, and pulmonary myeloperoxidase (MPO) activities were measured, guanosine triphosphate cyclohydrolase Ⅰ (GTP CHI), inducible nitric oxide synthase (iNOS), and tumor necrosis factor ? (TNF ?) mRNA expression were determined.Results Early treatment with PTX significantly decreased pulmonary MPO activities and TNF ?mRNA expression at 2 hours after CLP. Meanwhile, pulmonary biopterin, NO, GTP CHI, and iNOS mRNA expression levels were much lower in the treatment group than those in the non treatment group ( P

Objective To evaluate the role of spinal CX3C chemokine receptor 1 (CX3CR1) in inflammatory pain and the relationship with calmodulin (CaM)-calmodulin-dependent protein kinaseⅡ(CaMKⅡ) signaling pathways in mice.Methods Ninety-six pathogen-free healthy male C57BL6 mice,weighing 25-27 g,were divided into 3 groups using a random number table:control group (group C,n=30),inflammatory pain group (group IP,n=36) and CX3CR1 antagonist group (group CA,n=30).Inflammatory pain was induced by injecting complete Freund′s adjuvant (CFA) 50 μl into the plantar surface of right hind paws in IP and CA groups,while the equal volume of normal saline was given instead in group C.In group CA,CX3CR1 antagonist (diluted to 1 μg/5 μl in phosphate buffer solution) was intrathecally injected at 1 h before CFA injection.The thermal paw withdrawal latency (TWL) was measured at 30 min before CFA injection (T0) and 30 min,1 h,2 h and 4 h after CFA injection (T2-4).The animals were then sacrificed,and the spinal cord was removed for determination of the expression of phosphorylated CaMKⅡ (p-CaMKⅡ),phosphorylated cyclic adenosine monophosphate response element-binding protein (p-CREB) and c-fos (by Western blot) and expression of CaMKⅡ,CREB and c-fos mRNA (using real-time polymerase chain reaction).Immunofluorescence was used to determine that p-CAMKⅡ was expressed in microglia.Results Compared with group C,the TWL was significantly shortened at T2-4,and the expression of p-CaMKⅡ,p-CREB and c-fos protein and mRNA was up-regulated at T1-4 in IP and CA groups (P<0.05).Compared with group IP,the TWL was significantly prolonged at T2-4,and the expression of p-CaMKⅡ,p-CREB and c-fos protein and mRNA was down-regulated at T1-4 in group CA (P<0.05).p-CaMKⅡ was co-expressed with the microglial specific biomarker.Conclusion CX3CR1 is involved in the development and maintenance of inflammatory pain through activating CaM-CaMKⅡsignaling pathways in mice.

Objective To investigate the role of calcineurin(CaN)in inflammatory pain in rats.Methods Seventy-five male Harlan-Sprague-Dawley rats,weighting of 200-300 g were randomly divided into 3 groups (n=25): group control (group C),group CFA (complete Freunds adjuvant) (group F) and group CaN+CFA (group NF).100 μl CFA were injected on the right hind claw preparaing for inflammatory pain models in groups F and NF,100 μl saline were injected on the right hind claw in group C.CaN 10 U was intracerebroventricular injected 1 d before CFA injection in group NF.Paw withdrawal thermal latency (PWTL) were measured in 30 min prior to (T0),0.5 h (T1),1 h (T2),2 h (T3) and 4 h (T4) after injection.The expression of CaN and nuclear factor kappa B (NF-κB),IL-1β,TNF-α and IL-10 in spinal cord were measured at each time point.Results The PWTL was significantly shorter at T2-T4 in group F,at T3,T4 in group NF than that at T0and in group C (P<0.05);The PWTL at T2-T4 in group NF was significantly longer than that in group F (P<0.05).CaN protein expression in spinal cord at T1-T4 in group F,at T2-T4 in group NF was significantly lower than that of T0 and in the group C,NF-κB p65 protein expression was significantly higher than that of T0 and in the group C (P<0.05).CaN gene and IL-10 protein content at T2-T4 in groups F and NF were significantly lower than that of group C and at T0,NF-κB gene and IL-1β,TNF-α protein content was significantly higher than that of group C and at T0 (P<0.05).CaN protein and CaN gene expression,IL-10 protein content in spinal cord tissue at T1-T4in group NF was significantly higher than that of group F,NF-κB p65 protein and NF-κB gene expression and contents of IL-1β,TNF-α protein were significantly lower than that of group F (P<0.05).Conclusion CaN adjusts pro-inflammatory and anti-inflammatory cytokines by reducing NF-κB and inhibiting the process of inflammatory pain in rats.

Objective To discover the reciprocal regulation and its molecular mechanism of estro-gen, IL-6 and IL-8 in ovarian cancer cells. Methods Based on our previous studies, the effect of 17β-estradiol (E2) on the expression levels of IL-6, IL-8 and their respective receptors was investigated. Mean-while, the effect of IL-6/IL-8 on estrogen receptor (ER) expression and estrogen-dependent transcriptional activation was analyzed. Gene expression profile analysis revealed that CAOV-3 and OVCAR-3 cells, which express ER, IL-6 and IL-8 receptors, were suitable models for this study. Results We found that E2 not only enhanced IL-6/IL-8 secretion via NF-κB signaling pathway, but also modulated IL-6 and IL-8 receptors expression. Tamoxifen (Txf), an ER antagonist, completely abolished E2-stimulated IL-6/IL-8 expression. On the other hand, in the absence of estrogen, both cytokines increased ERα expression, decreased ERβ ex-pression, and activated estrogen-dependent transcriptional activation, which was completely blocked by Txf. Pretreatment of OVCAR-3 with p38 MAPK, MEK1/2 or ErbB2 MAPK inhihitors, respectively, IL-6-media-ted ER activation was blocked, while IL-8-indueed ER activation was blocked by Src inhibitor. Conclusion These data suggest that estrogen, IL-6 and IL-8 may form a mutual amplifying signaling which contributes to the growth and development of ovarian carcinoma.

Objective To discuss the application of implantation temporary cardiac pacing by balloon-tipped floating catheter for peroperative period patients. Method Thirty-three patients with severe bradyarrhythmia were received the balloon-tipped floating catheter to RV by Seldinger puncture technique.Meantime, the pacing signals of ECG were observed. The threshold and QRS waves to ensure the electrode position were determined. Result All of 33 cases were successfully punctured and 32 cases get paced, except 1 case had the electro - mechanical dissociation (EMD). Pacing threshold was less than 0. 9V, and mean remaining time was 12.47 ~ 161 (67. 05 ±34. 48) hours. Apical pacing was operated in 23 patients,and right ventricular outflow tract pacing in 10 patients. No severe complications were occurred. Conclusion The implantation method of temporary cardiac pacing by balloon-tipped floating catheter was convenient and safe. It could help the patients get safety in anesthesia and peroperative period.
