Objective To explore the inhibition effect of glutamine on the inflammation of rats with pneumonia induced by Klebsiella pneumoniae.Methods Thirty-six SD rats were randomly divided into the normal group,model group and glutamine treatment group.The rat pneumonia model was established by intratracheal instillation of Klebsiella Bacillus pneumonia.Results Compared with the model group,the glutamine treatmernt group could reduce the ratio of W/D(5.98±0.29)vs.(4.32±0.33)(P＜ 0.05),alleviated the lung tissue edema,inflammatory cell infiltration and then improved the morphology of the lung tissue,inhibited the IL-6,IL-1 and TNF-α secretion in serum and lung homogenate(P＜0.05),and inhibited the level of NF-κB p65 and IκBα phosphorylation.Conclusion Glutamine inhibits the inflammation of rats with pneumonia induced by Klebsiella pneumoniae,which might be related to NF-κB signal pathway.

Objective To observe the effect of Succinate injection combined with Bifico on the myocardial enzymes changes of the children with rotavirus enteritis.Methods A total of 146 children with rotavirus enteritis were enrolled and included in this study. Children were randomly divided into the control group (n=73) and the observation group (n=73). The control group was received Bifico on the basis of routine treatment, and observation group was received Succinate injection combined with Bifico. The IL-17, IL-6, TNF-?, LDH, CK, and CKMB was detected by ELISA. The rates of clinical effects was compared.Results After treatment, the IL-17 (22.35 ± 4.21 ng/mlvs. 30.24 ± 6.07 ng/ml,t=2.395), IL-6(31.26 ± 6.14 ng/mlvs. 43.72 ± 8.22 ng/ml,t=2.347), TNF-? (35.62 ± 6.24 ng/mlvs. 49.18 ± 8.72 ng/ml,t=2.421), LDH (135.16 ± 31.25 U/Lvs. 174.08 ± 40.22 U/L,t=2.373), CK (37.82 ± 7.39 U/Lvs. 50.21 ± 11.16 U/L,t=2.385), and CKMB (90.14 ± 11.63 U/Lvs. 113.22 ± 18.35 U/L,t=2.392) in the observation group were lower than those in the control group (P<0.05). The rates of clinical effects was 94.5% (69/73) in the observation group and 83.6% (61/73) in the control group. There was significant difference between the two groups (χ2=2.352,P=0.047).Conclusions The Succinate injection combined with Bifico could reduce the inflammatory indices and alleviate the myocardial injury in the RVE patients.

Objective To explore the effect of I kappa B kinase (IKK) on liver during hepatic ischemia reperfusion (HIR) in rats.Methods Wister rats were divided randomly into HIR group in which hepatic reperfusion was given after 60 minutes of ischemia by interruption of the arterial and portal venous blood supply to the left lobes and middle lobes of the liver; HIR + PDTC treatment group in which PDTC (120 mg/kg) were injected via the dorsum vein of penis before ischemia reperfusion; and sham control group in which midline laparotomy was performed without vascular occlusion and treatment.Expression levels of IKK were measured with In situ hybridization(ISH).The NF-κB activities were determined with EMSA.Expression levels of TNF-α were measured with immunohistochemistry (IH).Serum levels of ALT were measured.Results Expression level of IKK was increased markedly from 0 to 12h and peaked 6h after reperfusion in HIR group.NF-κB was activated 0 ～ 12h after reperfusion and activities of NF-κB were maximal 6h after reperfusion in HIR group rats compared with sham control group.Expression level of TNFα was increased markedly from 0 to 12h and peaked 6h after reperfusion in HIR group.Serum levels of ALT were increased significantly after reperfusion in H1R group.Expression level of IKK was lowered markedly in HIR + PDTC group from 0 to 12h after reperfusion.NF-κB activities were significantly lower in HIR +PDTC group than in HIR group from 0 to 12h after reperfusion.Expression level of TNF-α was lowered markedly in HIR + PDTC group as compared with HIR group from 0 to 12h after reperfusion.Serum level of ALT was decreased significantly after reperfusion in HIR + PDTC group as compared with HIR group.Conclusion HIR can activate IKK-β which promotes the activation of NF-κB,then NF-κB results in upregulation transcription of TNF-α gene which gives rise to the release of other inflammatory cytokines and triggers uncontrolled inflammatory response,and induces hepatic injury.Blocking IKK-NF-κB pathway may be an effective approach to checking the generation and development of ALI,PDTC plays important prophylaxis and treatment roles in hepatic injury after HIR.

To monitor the 24 h esophageal pH in patients with gastroesophageal reflux-induced cough (GERC) before and after omeprazole treatment. Methods The prospective study was conducted in Department of Gastroenterology, People's Hospital of Wuhan University from February 2007 to April 2008. Twenty patients with GERC received 40 mg of omeprazole daily and underwent 24 h esophageal pH monitoring before and 8 weeks after omeprazole treatment. Six parameters by Johson and Demeester were adopted for evaluation: pereentage of total time with pH <4, percentage of uptight reflux time with pH <4, percentage of supine reflux time with pH < 4, the number of reflux episodes with pH < 4, the number of reflux episodes longer than 5 min and the percentage of longest reflux duration. Results The values of six parameters before treatment were 13.5±8.5, 12.2±4.0, 15.8 ±4.1, 56 ± 13, 4. 15 ± 1.87 and 26.2 ± 16. 5 respectively; while those after treatment were 2.7± 1.3, 3.9 ± 1.9, 1.9 ± 1.0, 18 ± 11, 1.24 ±0.65 and 7.4 ± 2. 1. There were significant differences in these six parameters between pre-treatment and post-treatment (P<0.01 ). Conclusion The 24 h esophageal pH monitoring shows that omeprazole is effective in treatment of GERC by decreasing esophageal pH.

Objective To investigate the effects of angiotensin-converting enzyme inhibitor (ACEI) lisinopril on experimental diabetic peripheral neuropathy (DPN) in the earlier stage and its mechanism. Methods Diabetes was induced by streptozotosin (STZ) in rats. After 8 weeks of treatment, the effects of lisinopril on function and structure of peripheral nerves were observed; superoxide dismutase, malondialdehyde, Na+K+-ATPase activity in sciatic nerve and NO, NO synthase levels in plasma were determined, and capillary density of sciatic nerve were also assessed. Results With lisinopril, nerve structure and function was improved, oxidative stress state was ameliorated, and NO level, Na+K+-ATPase activity and capillary density of endoneurium were increased (all P<0.05). Conclusion ACEIs are effective in DPN. The possible mechanisms may be related to the amelioration of ischemic state and related metabolic disorders of the nerves.

Objective The aim of this study is to undemtand the development of peripheral nerve injury on diabetes mellitus.Methods Diabetes was induced by STZ.We determined nerve conduction velocity,thermal pain threshold,morphoh)gy changes of sciatic nerve and quantitative analysis of sural nerve of diabetic model group and normal control group after 2 weeks,4 weeks,6 weeks,8 weeks,12 weeks respectively,and observed dynamically functional and morphologic changes of peripheral nerve of diabetic rats.Results After 2 weeks,diabetic rats showed that motor and sensory nerve conduction velocities slowed down and thermal pain threshold decreased.After 4 weeks.changes of pathology of sciatic nerve were observed.With the duration extending,the damages of nerve were aggravated gradually.Conclusions Neumpathy appeared in earlier stage on experimental diabetic rats and functional changes were preceded to morphologic changes.
