In this study the role of acute administration of naloxone on LH pulse in normal adult men was evaluated. In 4 volunteers, blood samples were drawn at 10-min intervals for 10 hours both before and after administrating naloxone respectively for measurment of LH by RIA. The administration of naloxone resulted in an increase in LH pulse frequency from 5. 50?0. 50 to 8. 25?1. 09 (P

Oxidative stress is a major contributor to the pathogenesis of diabetes and diabetic complications.Heme oxygenase(HO),an important part of the human defense system,has been recognized to have significant physiological function against oxidative stress.HO can be stimulated by oxidative stress and decompose into carbon monoxide,biliverdin and iron,all with important anti-inflammatory,anti-oxidative stress and anti-apoptosis effects.Overexpression of HO induced by hyperglycemia can protect cells(including islet cells,endothelial cells and monocytes) and tissues from oxidative damage.Increased HO metabolic products not only maintain the physiological function of islet cells, delay diabetes progression,but also regulate vascular,nerve and muscle function,so as to prevent diabetic complications.

ObjectiveTo study the situation of neural invasion in pancreatic cancer and investigate its related clinical factors. Methods The neural invasion in 73 cases of pancreatic cancer patients was retrospective analysed. The correlation between neural invasion and clinicopathological parameters,and survival rate was investigated.Results In 73 cases of pancreatic cancer,neural invasion occurred in 38(52.1％) patients,among whom intra-pancreatic neural invasion rate was 15.8％ (n =6) ; and both intrapancreatic and external pancreatic plexus invasion rate was 84.2％ ( n =32).Neural invasion was not related with gender,age,and pathological type,degree of differentiation,tumor size and lymph node metastasis (P ＞ 0.05 ).But the presence of abdominal pain,vascular invasion,the expression of EGFR and VEGF in tumor tissue was significantly related with neural invasion (P ＜0.01 ).The median survival of patients in neural invasion group was 8 months,which were significantly shorter than that of in patients without neural invasion (13 months,x2 =4.69,P =0.030).Conclusions Neural invasion has a high incidence in pancreatic cancer,and it can cause obvious abdominal pain.And it is related with vascular invasion and the expression of EGFR and VEGF in tumor tissue.Neural invasion is one of the factors affecting the survival rate.

The characteristics of glucose dysbolism in ectopic ACTH syndrome (EAS) were investigated by analysing the clinical data of 117 patients with Cushing syndrome (CS). The patients with CS were divided into 3 groups : EAS group (n = 9) , Cushing's disease (CD) group (n = 67) and adrenocortical adenoma (AA) group (n =41). Retrospective analysis of the data covered the prevalence of secondary diabetes, blood glucose, HbAlc, blood potassium, and blood ACTH and 24 h urinary-free cortisol (UFC) levels. Compared with CD and AA groups, the prevalence of secondary diabetes and blood glucose level were higher in EAS group, while HbAlc level was lower. Blood glucose level in patients with ectopic ACTH syndrome decreased to normal after tumor removal.

Objective To investigate the inhibitory effect of proliferation and invasiveness on PANC1 cell by knockdown of NF-κB P65 expression through RNA interference. Methods Chemically synthesized small interference RNA (siRNA) directed against human NF-κB p65 was transfected into pancreatic carcinoma cell (PANC1) by using cationic liposome LipofectamineTM 2000 as the transfection agent. A non-silencing siRNA was used as the negative control and distilled water was used as the blank control. The tests repeated for six times. The expression of NF-KB p65 and ICAM-1 gone was detected by RT-PCR. The effect of cell proliferation and invasive ability was evaluated by MTF, clony assay, Matrigel invasive tests. Results The relative expression levels of NF-κB p65 mRNA in siRNA, the negative control and the blank control group were 0.227 ±0.045, O. 381 ± 0. 038 and 0. 404 ± 0. 031, respectively; the relative expression levels of ICAM-1mRNA were 0.597 ± 0. 083, 0.983 ± 0.068 and 1. 027 ± 0.098, respectively; the inhibitory rate of the cells at 72h were 18.3%, 2.3% and 0, respectively; the colony forming efficiency were ( 14.1 ± 3.1 ) %, ( 24.5±2.1)% and (27.2 ±2.6)%, respectively; the number of invasive cells were 80.25 ±6.35, 123.83 ±8.80 and 127.68 ± 9.23, respectively; the difference between the siRNA group and two control groups was significant (P ＜ 0. 01 ). Conclusions Down-regulatiag the expression of NF-κB p65 gene by RNAi may inhibit proliferation and invasiveness in pancreatic carcinoma cell strain PANC1.

Objective: To observe the effect of ω-3 fish oil emulsion on the experimental severe acute pancreatitis(SAP)through the morphologic alteration of pancreas,the level of serum amylase(AMS)and the functions of liver and kidney,and explore its possible mechanism. Methods: Rat model of SAP was produced by injecting 5% Sodium Cholate(1 ml/kg)into the biliopancreatic duct.Male Sprague-Dawley rats were randomly divided into 4 groups: normal group(n=6),fish oil emulsion treatment group(FOG,n=18),soybean oil emulsion treatment group(SOG,n=18) and normal sodium treatment group(NSG,n=18).Then fish oil emulsion(FO,10 ml/kg);soybean oil emulsion(SO,10 ml/kg)and normal sodium(NS,10 ml/kg)were intravenously injected respectively 120 minutes.The pancreatitis were confirmed by levels of serum AMS and histopathologic score.ALT,AST,BUN and Cr were tested 24 hours after the treatments.Expressions of IL-1β and IL-10 were tested by ELISA.The activated NF-kappa B was examined in the pancreases. Results: Lower level of serum AMS(P<0.05)and lower histopathology score(P<0.05) appeared in FOG.Compared with NS,FO decreased the levels of serum ALT and BUN significantly (P<0.05).FO significantly attenuated the expression of IL-1β (P<0.05).FO downregulated the activity of NF-kappa B efficiently.Conclusions: By down-regulating the levels of IL-1β together with up-regulating the level of IL-10,FO reduces inflammatory damage at the beginning of AP.
