Aim To study IL-8 expression of human airway epithelium-like NCI-H292 cells directly induced by Pyocyanin and its mechanism through protein kinase C(PKC) and nuclear factor-kappa B(NF-??).Methods ELISA methods were performed to test the expression of IL-8 in NCI-H292 cells infected by Pyocyanin.Western blot was employed to examine the expression of NF-?B protein.In addition,NCI-H292 cells were cultured together with PKC inhibitor,calphostin C or NF-?? inhibitor,pyrrolidine dithiocarbamate(PDTC),respectively before Pyocyanin infection,then the expression of IL-8 and NF-?? was assayed using the above methods.Results Pyocyanin was able to induce IL-8 protein secretion in NCI-H292 cells and had marked concentration-dependent relations.Pyocyanin could also significantly promote the activation of NF-?B,which peaked at 60~90 min.PDTC and calphostin C could significantly decrease the activation of NF-?? and the expression of IL-8.Conclutions Pyocyanin can induce IL-8 production.The direct induction of Pyocyanin can promote the activation of NF-?B by PKC signal pathway,then cause the expression and secretion of IL-8.

Objective Cellular response to estradiol is mediated both by estrogen receptor (ER) binding to estrogen response element (ERE) and by non-nuclear actions like activation of signal transduction pathways such as mitogen activated protein kinase (MAPK) pathway. However, the signal transduction of estrogen involving phosphatidylinositol 3-kinase-protein kinase B (PI3K -PKB) is not clear in endometrial carcinoma. Our purpose was to study if PI3K-PKB signaling pathway could be activated rapidly by 17?-E 2 through non-nuclear action and also, whether PI3K inhibitor, LY294002, could inhibit such non-nuclear action of 17?-E 2 in endometrial carcinoma cell line Ishikawa. Methods Levels of phosphorylated PKB(Ser473 site, p-PKB) and total PKB were examined by western blotting in Ishikawa cells after stimulation with 17?-E 2 at 1?10 -6 mol/L for different time periods and at varied doses for 30 min. Optimal time and appropriate dose for 17?-E 2 to activate PKB in Ishikawa cells were observed. Inhibitory effect of LY294002 on activation of PKB induced by 17?-E 2 was also studied. p-PKB/PKB ratio was used to indicate levels of activation of PKB. Results p-PKB/PKB at 15 min (0.533?0.029) was significantly higher than the control (0.361?0.029, P 0.05, 0.05,

Objective To investigate the effect of anti-inflammation-analgesic injection (AIAI) combined with extract from rabbit skin inflamed by vaccinia virus (ERSVV) on repair of the damaged sciatic nerve in rats.Methods Fifty adult SD rats of both sexes weighing 260-300 g were randomly divided into 5 gronps ( n = 10each): sham operation group (group S); sciatic nerve chronic constriction injury group (group CCI); CCI + AIAI group (group A); CCI + ERSVV group (group E) and CCI + AIAI + ERSVV group (group A + E). Right sciatic nerve was exposed and 4 loose ligatures were placed on the sciatic nerve at 1 mm intervals with 4/0 catgut in CCI,A,E and A + E groups. A catheter was placed around sciatic nerve, and fixed to the nearby muscle and kept unclogged by injecting 0.2 nl distilled water daily. AIAI and/or ERSVV 0.2 ml were injected via the catheter starting from the 14th day after operation. AIAI 0.2 ml contained dexamethasone palmitate (4 mg/ml) 0.05 ml, 2% lidocaine 0.05 ml and vitamin B12 (0.5 mg/ml) 0.05 ml in distilled water. Dexamethasone palmitate was omitted in AIAI starting from the 2nd of drug administration in group A and A + E. Paw withdrawal threshold to mechanical stimulation (MWT) was measured before (baseline) and at 1, 5, 7, 14, 21 and 28 days after operation. Sciatic nerves were exposed at 14 and 28 days after operation in 5 rats in each group. Conduction velocity of motor nerve (NCV) and action potential (AP) of gastrocnemius muscle were measured. Sciatic nerve at the site of CCI was examined for pathologic changes, the number of axons (NA) and thickness of myelin sheath (TMS) with light microscope. Results CCI significantly decreased MWT, AP, NA, TMS and NCV in group CCI as compared with group S (P <0.01). AIAI and/or ERSVV significantly attenuated CCI-induced decrease in MWT, AP, NA, TMS and NCV in A,E and A + E groups as compared with CCI group ( P < 0.05). Their curative effects were potentiated by combined use. Conclusions Both AIAI and ERSVV have curative effects against CCI-induced sciatic nerve injury and their actions are potentiated by combined used.
