Objective To explore association between the changes of myenteric nerve plexus and the delayed gastrointestinal transit in acute necrotic pancreatitis (ANP) rat complicated with hyperlipemia. Methods Atotal of 40 male Sprague-Dawley (SD) rats were randomly divided into 4 groups (normal control group, ANP group, hyperlipemia (HL) control group and HL with ANP group). HL rat model was established by fed with high-fat diet for 4 weeks, and ANP rat model was induced by retrograde injection of 3.5% sodium taurocholate into pancreatic duct. Gastrointestina1 transit distance was measured by ink gavage method. The histological changes of cholinergic and nitriergic nerves in myenteric plexus were observed by Karnovsky-Root method and NADPH histochemistry method. Results Pathological injuries were more severe in HL with ANP group than in ANP group (12.8±0.63 vs. 10.8±1.93,P<0.01), gastrointestinal transit was obviously delayed (transmission rate was 27%±5% vs. 38%±6%,P<0.01), the density of cholinergic neurons decreased (4.80±1.23 vs. 5.80±0.79, P<0.05), and the density of nitriergic neurons significantly increased (8.70±0.75 vs. 6.80±1.48, P<0.01). There was a linear regression between changes of cholinergic and nitrievgic nerves in myenteric nerve plexus and gastrointestinal transit (R2=0.531, P<0.01). Conclusion There was significant gastrointestinal motility disorder in the ANP rat complicated with hyperlipemia, which may be closely related with the changes of myenteric nerve plexus.

12 ml/s was used as Group A and Qmax ≤12 ml/s as Group B. Results One week after removal of urinary catheter, dysury appeared in five cases with Qmax for (9.45?2.62) ml/s, of which two cases were with posterior urethral stricture, two with benign prostatic hyperplasia and one with weak detrusor contraction. Three months after removal of urinary catheter, six cases led to secondary dysuresia due to posterior urethral stricture and had Qmax for (6.28?3.26) ml/s, with significant difference compared with urodynamic parameters of normal group (P

Objective To investigate the relationship between insulin like growth factor (IGF Ⅰ)、IGF Ⅱ and IGFBP 3 and Child Pugh classification in patients with liver cirrhosis and to determine the potential clinical markers of functional hepatic reserves. Methods Forty four patients with posthepatitic cirrhosis were divided into 3 groups according to disease severity (Child Pugh Score) and 38 healthy subjects severed as controls. Serum levels of IGF Ⅰ, IGF Ⅱ and IGFBP 3 were measured in these groups by immunoradiometric assay. Results Baseline IGF Ⅰ, IGF Ⅱ and IGFBP 3 levels were significantly lower in patients with cirrhosis than in controls, and the serum concentrations of IGF Ⅰ, IGF Ⅱ and IGFBP 3 were associated with the marked changes of liver function due to Child Pugh score. They all showed a significant correlation with the degree of hepatic dysfunction and dropped markedly during the progression of liver failure. The sensitivity of IGF Ⅱ is much higher than that of IGF Ⅰ and IGFBP 3. It was found that IGF Ⅰ

Objective To evaluate the application of M2A capsule endoscopies ( CE) in the diagnosis of digestive tract diseases. Methods Forty - five patients (26 males, 19 females) , suffered from gastrointestinal bleeding, abdominal pain or chronic diarrhea were referred to this study and underwent capsule endoscopies. Their average age was 47. 8 years old (a range of 15 - 78). Capsule endoscopies were performed with the Given M2A video capsule system. The conventional diagnostic procedures (including small bowel radiograph, gastroenteroscopy, colonoscopy, etc. ) were done in 31 patients before or after the CE, thus the results of both procedures were compared. Results Among 45 patients, 44 have completed CE successfully. Any complication never experienced. The quality of photos was excellent. The significant pathological findings were revealed in 37 patients, diagnostic yield was therefore 84. 1% . Patients with esophagogastric diseases, small bowel diseases and colon diseases were found in 5,29 and 3 cases respectively. Thirty -one patients received a conventional diagnostic procedure before or after CE. Twenty one of them suffered from GI bleeding, pathological changes were found in 17 patients by capsule endoscopies, only 4 patients by conventional procedure; five of them suffered from abdominal pain, pathological changes were found in 5 patients by CE, only 2 patients by conventional procedure; 4 of them suffered from chronic diarrhea, pathological changes were found in 4 patients by CE, only 1 patient by conventional procedure. The pathological sites located by CE were quite similar to those by conventional diagnostic work-up. Conclusion CE has the advantages of high safety, excellent visualization and precise localization. Its efficiency in diagnosis is much better than that of conventional procedure, and is indispensable in the diagnosis of digestive tract diseases.
