Objective To elucidate the airway inflammation status in mice infected with respiratory syncytial virus (RSV), and whether the inflammation could be alleviated by small interference RNA (siRNA) targeting specific RSV gene. MethodsBALB/c mice were infected with RSV via intranasal instillation of RSV suspension, and were then treated with specific siRNA targeting RSV-M2 gene. ELISA assay was used to detect the levels of IFN-γ, IL-12 and IL-10 and Microscope was used to count white blood cells in bronchoalveolar lavage fluid(BALF). ResultsAfter RSV infection, a significant increase in leukocytes count was observed in BALF. Differential count showed a rise in the percentage of neutrophils, eosinophil, especially lymphocytes and a reduction of the percentage of monocytes and macrophages( P＜0.05 ).The levels of IFN-γ, IL-12 and IL-10 were also increased(P＜0.05). Furthermore, the leukocytes count,the percentage of lymphocytes, neutrophils and eosinophil, and the levels of IFN-γ, IL-12 and IL-10in BALF were decreased accordingly while the mice were given higher concentrations of siRNA ( P＜0.05 ).Conclusion RSV caused airway inflammation in BALB/c mice, which may be alleviated by RNAi technology.

AIM: To detect the changes of heme oxygenase-1 (HO-1) expression in kidney following ischemia-reperfusion of hindlimbs and to elucidate their significance. METHODS: Health SD rats were randomly divided into normal (N), sham (S), 4h ischemia without reperfusion (I), 4 h ischemia-2, 6, 12, 18 or 24 h reperfusion (I-R) groups and I-R18h+zinc protoporphyrin (ZnPP) group. I-R was established using the occlusion for 4 h and re-opening for 2-24 h of the femoral arteries. In I-R 18 h+ZnPP group, ZnPP (5 ?mol?kg~(-1) body weight) was intravenously injected 6 h and 12 h after reperfusion, respectively. The expression of HO-1 mRNA in kidney was detected with reverse transcription-polymerase chain reaction (RT-PCR). The expression and location of HO-1 protein were detected with immunohistochemical technique. The observation of pathologic changes of kidney was made following the inhibition of HO-1 by ZnPP. RESULTS: The relative expression level of HO-1 mRNA significantly increased in I-R group, compared to those in the control groups, It was maximal in I-R 18 h group, and thereafter expression level of HO-1 mRNA decreased, however significant expression was still detected in I-R 24 h group (P

Objective To investigate the effect of Cimetidine on the adhesion between colorectal cancer LOVO cells and endothelial ECV304 cells;and study whether Cimetidine can inhibit the expression of E-selectin in ECV304 cells. Methods Cellular uptake of rose Bengal stain was used to measure the adhesion between LOVO cells and ECV304 cells. Enzyme-linked immunosorbent assay(ELISA)and flow cytometry (FCM, indirect fluorescence staining and labeling)were used to detect the expression of E-selectin. Results ECV304 cells were exposed to different concentrations of Cimetidine. Both the adhesion between LOVO cells and ECV304 cells and the levels of E-selectin significantly decreased with increasing concentration of Cimetidine(P =0. 001 and 0. 001 respectively). Conclusion Cimetidine can inhibit the adhesion of human colorectal cancer LOVO cells on endothelial ECV304 cells by blocking E-selectin expression. Our observations indicated a potential of anti-adhesion therapy using Cimetidine in cancer treatment.

Objective To set up the molecular cytobiological model of endogenous coagulation factor Ⅷ (FⅧ) re-expressing in human liver cells L02,and to study the regulation pathway and molecular basis of the re-expression of FⅧ in L02 cells activated by NO signal.Methods The L02 cells at logarithm growth phase were selected and randomly divided into blank control group and experimental group, inhibitor group and inhibitor control group;they were cultured for 0,12,24,36,48,and 60 h.Flow cytometry was used to detect the expression of human FⅧ protein in L02 cells after treated for 48 h.Griess experiment was performed to detect the levels of NO in L02 cells at different time points;the transcription levels of human FⅧ gene,iNOS gene,NF-κB1 gene and I-κB alpha gene were detected by RT-PCR method.Western blotting method was used to detect the expression levels of human phosphorylated I-kappaB (phosphorylated I-κB)in L02 cells.Results The results of flow cytometry showed that the expression of human L02 FⅧ protein was found after treated with L-arginine for 48 h. The Griess results showed that the levels of NO in L02 cells in experimental group were significantly increased at 3,6,12,and 24 h (P<0.05)and the levels of NO in blank control group,inhibitor group and inhibitor control group had no changes. The RT-PCR results showed that the transcription of human FⅧ mRNA in L02 cells was found in experimental group,but there was no transcription of human FⅧ mRNA in blank control group,inhibitor group and inhibitor control group;the transcription levels of iNOS,NF-κB1 and I-κB alphain experiment group were increased(P<0.05)and the transcription levels of these genes in blank control group,inhibitor group and inhibitor control group had no changes. The Western blotting results showed that after adding L-arginine the expression level of phosphorylated I-κB was significantly increased (P < 0.05 ), other groups had no such change. Conclusion L-arginine can activate the phosphorylation of I-κB by NO signal pathway to lead to the changes in the expression of human FⅧ gene promoter upstream regulatory-related transcription factors NF-κB to activate the expression of human FⅧ in human liver cells L02.

AIM: To detect the changes of inducible nitric oxide synthase (iNOS) expression in kidney following ischemia-reperfusion(I-R)of hindlimbs and to elucidate their significance. METHODS: I-R was established using the occlusion of the femoral arteries for 4 h and re-opening for 2-24 h in rats. The expression of iNOS mRNA,and iNOS protein and the nitrotyrosine (NT),a marker of peroxynitrite (ONOO -),in renal tissue were detected with reverse transcription-polymerase chain reaction (RT-PCR) and immunohistochemical technique,respectively. The superoxide dismutase (SOD) activity and malondialdehyde (MDA) contents in renal tissue were spectraphotometrically measured. The observation of pathologic changes of renal tissue was made following the inhibition of iNOS by aminoguanidine (AG). RESULTS: Compared with control group,the relative expression level of iNOS mRNA significantly increased in I-R group. There were more iNOS and more NT positive product in the epithelial cells of renal proximal convoluted tubules and thick segments of Henle′ loops in I-R group than control group. The contents of MDA markedly increased,while the activity of SOD significantly decreased in I-R group,compared to those in the control groups. The pathologic changes of kidney became milder in I-R group following the inhibition of iNOS by AG. CONCLUSION: The expression of iNOS mRNA and protein in renal tissue were significantly upregulated,excess induction of NO contributed to the kidney injury during the I-R of hindlimbs.

BACKGROUND:Abnormal gaits are very common in children with cerebral palsy, and how to improve the gait is the focus of rehabilitation therapy. OBJECTIVE:To analyze the biomechanical parameters of gaits in cerebral palsy children and to observe the effects of brace control on the exercise capacity of dyskinetic cerebral palsy children. METHODS:In this paper, we compared the biomechanical parameters of children with cerebral palsy and normal children in the initial process of walking and during walking. Biomechanical parameters in the initial process of walking include spatial and temporal parameters, kinematic and kinetic parameters of the range of motion of the knee and ankle. Biomechanical parameters during walking include spatial and temporal parameters. With the aid of hand brace, dyskinetic cerebral palsy received postural control, gait training, and sling exercise therapy for 3 months. The Gross Motor Function Measure (GMFM-88) assessment and video control were conducted for evaluation of therapeutic efficiency. RESULTS AND CONCLUSION:Biomechanical parameters in the initial process of walking showed significant differences between children with cerebral palsy and normal children except for the peak of ground reaction force at frontal axis with the right foot to start walking. Biomechanical parameters during walking showed that the stance phase and bipedal stance phase were prolonged, while the step length and stride length were shortened in the children with cerebral palsy compared with the normal children. For cerebral palsy children with brace control, the GMFM-88 scores were significantly decreased after treatment, involuntary movements were reduced shown on the video, the neck and body were stable, and life skil s were improved. Children with epilepsy and cognitive impairment or who had imaging changes in the basal ganglia showed a little improvement, and children with dance-athetoid type and dystonia type had a better progress than those with athetoid spasm.
