Changes and Mechanism of Colon Motility of the Rats in Multiple Organ Dysfunction Syndrome Induced by Bacterial Peritonitis

【Abstract】ObjectiveTo explore the changes of colon motility of the rats in multiple organ dysfunction syndrome （MODS） induced bacterial peritonitis and the effects of IL6, TNFα and induce nitricoxide synthase (iNOS) on colon motility. MethodsWistar rats were divided into two groups, which were the control group and the MODS group. The number of stool, the amplitude changes of circular smooth muscle strip, the length of smooth muscle cell, and the changes of serum NO in two groups were observed. The expressions of IL6, TNFα and iNOS protein and IL6 mRNA, TNFα mRNA and iNOS mRNA in distal colon were investigated by using immunohistochemical methods and RTPCR. ResultsThe numbers of stool and the amplitude in the MODS group were lower than those of the control group （P＜0.05）. The expressions of IL6, TNFα and iNOS were negative in the control group, while they were positive in the MODS group. IL6 mRNA,TNFα mRNA and iNOS mRNA were negative expression in the control group, but they were positive expression in the MODS group. The concentration of serum NO and the length of smooth muscle cells in the MODS group were higher than those of the control group (P＜0.01). ConclusionColon motor dysfunction of the rats is related to the iNOS, IL6 and TNFα.

Plasma Level of Adiponectin and Its Relationship with Interleukin-17 in Patients with COPD

【Abstract】 Objective To observe the plasma levels of adiponectin and interleukin-17 ( IL-17) in patients with chronic obstructive pulmonary disease ( COPD) at acute exacerbation or stable stage, and analyze their relationship. Methods Sixty male COPD patients with normal weight ( with BMI range of 18. 5-24. 9 kg/m2 ) were enrolled, including 30 patients with acute exacerbations of COPD ( AECOPD) and 30 patients with stable COPD. Twenty healthy nonsmoking male volunteers were included as controls. The plasma levels of adiponectin and IL-17 as well as lung function ( FEV1% pred and RV% pred) were measured in all subjects. Results The concentrations of adiponectin and IL-17 were significantly higher in the AECOPD patients than those of the patients with stable COPD and the contro1s ( P lt; 0. 001) . Theconcentrations of adiponectin and IL-17 were significantly higher in the patients with stable COPD than those of the controls ( P lt;0. 01) . Adiponectin was positively correlated with IL-17 in the AECOPD patients ( r =0. 822, P lt;0. 001) and in the patients with stable COPD ( r =0. 732, P lt;0. 001) . Adiponectin was positivelycorrelated with RV% pred in the AECOPD patients ( rs = 0. 764, P lt;0. 001) and in the patients with stable COPD ( rs =0. 967, P lt;0. 001) . There was no significant relationship between adiponectin and FEV1% pred ( P gt;0. 05) . Conclusions The plasma level of adiponectin in COPD patients is elevated which is relatedwith excessive inflation of lung. Adiponectin may be involved in the process of inflammation in COPD as a new pro-inflammatory cytokine.

Effects of Ginkgo Biloba Extract on Expressions of IL-1β, IL-6, and TNF-α in Brain Tissues of Rats with Severe Acute Pancreatitis

Objective　To investigate the effects of ginkgo biloba extract （GBE） on expressions of IL-1β, IL-6,and TNF-α in the pancreas and brain tissues of rats with severe acute pancreatitis （SAP）, and further to explore the pathogenesis of SAP and the efficacy of GBE on brain injury. Methods　Fifty-four Winstar rats were randomly divided into normal control group, model group, and treatment group, with 18 rats for each group. For rats in the normal control group, only conversion of pancreas was performed by abdomen opening , followed by wound closure immediately. For rats in the model group and treatment group, 5% sodium taurocholate hydrate were injected under pancreatic capsule to establish SAP model, and then GBE and normal saline were infected into intra-abdomen repeatedly every 8 hours, respectively. At 6 h, 12 h, and 24 h after the model establishment, experimental samples were extracted and serum amylase was detected. Pathogenic scoring for pancreas tissues was performed under light microscopy, and immunohistochemistry method was employed to detect the expression levels of IL-1β, IL-6, and TNF-α in pancreas and brain tissues. Results　For the treatment group, both serum amylase and pancreas scoring were significantly lower than those of the model group （P＜0.01）. At 24 h after model establishment, the expressions of IL-1β, IL-6, and TNF-α of pancreas tissues in model group were significantly higher than those at 6 h and 12 h （P＜0.05 or P＜0.01）, but no significant differences wereobserved in treatment group （P＞0.05）. The expressions of IL-1β, IL-6, and TNF-α of brain tissues in model group were significantly higher than those at 6 h and 12 h （P＜0.05 or P＜0.01）, but in treatment group decreased （P＜0.05 or P＜0.01）. The expressions of IL-1β, IL-6, and TNF-α in the treatment group were significantly lower than those of the model group at same time （P＜0.01）. Conclusions　During SAP, the expressions of IL-1β, IL-6 and TNF-α in pancreas and brain tissues increased obviously. GBE showed suppressing and scavenging effects on IL-1β, IL-6 and TNF-α in pancreas and brain tissues.

恶性梗阻性黄疸患者手术前后IAP和sIL-2水平变化的意义

Current status and progress of interleukin-6 in Takayasu arteritis

ObjectiveTo summarize the research status and progress of interleukin-6 (IL-6) in Takayasu arteritis (TAK). MethodRecent literature published at home and abroad about the study of IL-6 in the TAK was reviewed and analyzed. ResultsIL-6 was a pro-inflammatory cytokine secreted by a variety of cells, which participated in a variety of inflammatory and immune reactions, and played an important role in the progress of TAK. The expression levels of IL-6 in the peripheral blood and vascular wall tissues of patients with TAK were increased. The gene polymorphism of IL-6 might be related to the occurrence of TAK. Tocilizumab, an IL-6 receptor antagonist, was effective and safe in the treatment of TAK. ConclusionsIL-6 can be used as one of the monitoring indicators for the active phase and recurrence of TAK. IL-6 receptor antagonist can be used as the treatment choice of TAK, but the application results in different stages of TAK are still worth expecting.

Effect of different resuscitation fluids on interleukin-8 and tumor necrosis factor-α in rats with traumatic hemorrhagic shock

Objective To investigate effect of different resuscitation liquids and different resuscitation methods on contents of interleukin-8 (IL-8) and tumor necrosis factor-α (TNF-α) in early resuscitation process of rats with traumatic hemorrhagic shock. Methods Sixty-four healthy SD rats (450–550 g) were chosen and divided into 4 groups randomly and averagely: crystal liquid limited resuscitation group, colloidal liquid limited resuscitation group, 7.5% NaCl limited resuscitation group, and colloidal liquid non-limited resuscitation group. There were 16 rats in each group. All the experimental rats were weighed before intraperitoneal injection of pentobarbital sodium anesthesia. Animal model was established via Chaudry’s method. The rats were killed and the abdominal aorta bloods were drew on hour 2, 6, 12, and 24 after recovering from anesthesia. The contents of IL-8 and TNF-α in plasmas were detected by enzyme linked immunosorbent assay. Results The contents of IL-8 and TNF-α among three kinds of limited resuscitation groups on hour 6 after resuscitation were significantly higher than those on hour 2 after resuscitation (P<0.05) and reached the peaks, then began to decrease. On hour 12 after resuscitation, the contents of IL-8 and TNF-α were decreased continuously among three kinds of limited resuscitation groups (P<0.05). The contents of IL-8 and TNF-α in the colloidal liquid non-limited resuscitation group at each point time were significantly higher than those among three kinds of limited resuscitation groups (P<0.05), which in the crystal liquid resuscitation group were significantly lower than those in the other limited liquid resuscitation groups (P<0.05). Conclusions In process of liquid resuscitation of rats with traumatic hemorrhagic shock, limited resuscitation method is better than that of non-limited resuscitation method. Among three kinds of limited resuscitation methods, crystal resuscitation liquid is more effective than the other two resuscitation liquids in prohibiting releases of IL-8 and TNF-α in rats with traumatic hemorrhagic shock.
