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 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 To explore the effect of NF-?B activation induced by lipopolysaccharide(LPS) in rat Kupffer cells(KCs). Methods KCs were divided randomly into three groups. A group was control group. KCs were co-cultured with LPS in B group. KCs were co-cultured with LPS and PDTC in C group. NF-?B activity of KCs was determined with EMSA. Content of I-?B protein in KCs was detected with western blot. Expression levels of TNF-? mRNA, IL-6 mRNA of KCs were measured with RT-PCR. Results LPS induced NF-?B activation of KCs, decreased I-?B content of KCs, and increased expression levels of TNF-? mRNA and IL-6 mRNA markedly. PDTC could diminish the above effects of LPS on KCs. Conclusions NF-?B activation induced by LPS may induce cell injury by promoting expressions of TNF-? mRNA and IL-6 mRNA in KCs. PDTC could decrease mRNA expression of proinflammatory mediators by suppressing excessive NF-?B activation in KCs.

Using inverted microscopy and circuit TV, the morphological type, diameter of arteriovenous anastomoses (AVAs) in 11 rabbit's ear chambers were observed. According the joining forms with arterioles and venules in 68 AVAs, there were 4 types: type Ⅰ 58.8%, type Ⅱ 19.4%, type Ⅲ 11.1%, type ⅣV 10.7%. The inner diameters of the AVAs when dialated, measured 36.6?1.67?m at their arterial ends, 16+0.6?m at their narrow points, 66?4?m at their venous ends.This study showed that dilation of AVAs in the rabbit's ear is a graded response which correlates with the rise in intravertebral canal temperature. Some AVAs have multiple venous segments which vary in diameters. It was observed that the behaviour were different after intravertebral canal warming.

AIM:To explore the effect of erythropoietin ( EPO) on the expression of myocardial NADPH oxi-dase (Nox) in the pressure overload rats.METHODS:Male SD rats (n=36) were used to establish a pressure overload myocardial hypertrophy model by abdominal aorta ligation.The animals were divided into model group, control group ( sham, without narrowing abdominal aorta, the rest of the operation was the same as the model) and recombinant human erythropoietin ( rhEPO) treatment group ( intraperitoneal injection of rhEPO postoperatively, 4 000 U/kg, twice a week) . After 8 weeks, the cardiac ultrasound imaging and hemodynamic evaluation were conducted to determine the cardiac func-tions.Masson staining was used to observe the degree of myocardial fibrosis.The expression of Nox2 and Nox4 at mRNA and protein levels was detected by real-time quantitative PCR and Western blotting.The protein levels of myocardial inflam-matory factors CD45, F4/80 and TGF-βwere determined by Western blotting.RESULTS:Compared with model group, the left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-systolic pressure (LVESP) and left ventricular pressure maximum rising and falling rates ( ±dp/dtmax) increased significantly in EPO treatment group (P<0.01).At the same time, left ventricular end-systolic diameter (LVESD), left ventricular end-diastolic diameter ( LVEDD) and left ventricular end-diastolic pressure ( LVEDP) were decreased in EPO treatment group (P<0.01).EPO reduced the degree of myocardial fibrosis caused by pressure overload (P<0.01) and decreased the ex-pression of Nox2 and Nox4 at mRNA and protein levels in the myocardium (P<0.05 or P<0.01), and reduced the pro-tein expression of myocardial inflammatory factors CD45, F4/80 and TGF-β.CONCLUSION: EPO inhibits rat myocar-dial fibrosis induced by pressure overload, improves heart functions by decreasing NADPH oxidase activity and inhibiting myocardial oxidative stress levels and myocardial inflammatory reaction.

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.
