Objective To investigate the effects of propofol anesthesia on cognitive function of aged rats. Methods Ninety-six male aged SD rats (16 months) were collected and given propofol anesthesia via tail vein catheter. At 7, 30, and 90 d after anesthesia, fear conditioning experiment was performed to test long-term memory of the aged rats (12 rats at each time point, total 36 rats). At 1, 2, 3, 4, and 5 d after anesthesia, spontaneous alternation in Y-maze experiment was performed to test spatial working memory of the aged rats (12 rats at each time point, total 60 rats). Results There were no statistical differences in long-term memory at 7, 30, and 90 d after anesthesia between the propofol group and control group (P>0.05). While spatial working memory of aged rats in propofol group was impaired at 1 and 2 d after anesthesia (P<0.05), working memory of aged rats in propofol group was normal at 3, 4, and 5 d after anesthesia and there were no statistical differences between the experiment and control group (P>0.05). Conclusions These results indicate that clinical dose propofol anesthesia will not induce long-term memory impairment of aged rats, although it impairs spatial working memory of aged rats within 48 h after anesthesia.

Objective To observe the expressions of Th1 cytokin [interleukin (IL)-12] and Th2 cytokin (IL-4) in gut of the mouse model of postinfcctious irritable bowel syndrome (PI-IBS). Methods Thirty mice were divided into control group (n=8) and model group (n=22,infected with Trichinella spiralis). The weight of the mouse was measured weekly after infection. Visceral sensitivity of colorectal distention in mouse was accessed by abdominal withdrawal reflex (AWR) at 0 and 8 weeks after infection. All mice were sacrificed at the 8th week, and tissues of jejunum, terminal ileum, proximal colon and distal colon were observed for inflammation with HE staining. The mRNA and protein expressions of IL-12 and IL-4 were examined by RT-PCR and Western blotting, respectively. Results Two weeks after infection, body weight was decreased in model group compared with control group ( -1.08%±1.08 % vs 3.09%±1.85%, P<0.05), but there was no significant difference at the 8th week between two groups (P>0.05). Severe inflammation was observed in the gut of mouse 2 weeks after infection, however it was recovered at the 8th week. The score of AWR was higher in model group at 30,45 and 60 mmHg in comparison with control group (P<0.05), whereas the perceptual threshold was lower in model group than in the control group (P<0.05). In comparison with control group, increased expressions of IL-12 mRNA and protein in ileocecum and proximal colon as well as decreased expressions of IL-4 mRNA and protein in all parts of gut were found in model group (P<0.05). Conclusion Th1/Th2 shift may involve in gut of PI-IBS mouse, which provides a new idea for treatment of PI-IBS.

Objective To evaluate the sensitivity and specificity of Rome Ⅲ criteria in diagnosis of functional dyspepsia (FD) and assess its value in differentiate FD from other organic diseases in upper gastrointestinal tract. Methods Four thousand nine hundred and sixty-two patients, who underwent gastroscopy from July to August 2006 and March to April 2007, were consecutively enrolled and interviewed face to face with a standard questionnaire. The patients who were diagnosed as FD were according to Rome Ⅲ criteria, and those who were diagnosed as upper gastrointestinal diseases, such as chronic erosive gastritis (CEG), gastric ulcer (GU), duodenal ulcer (DU) and gastric carcinoma (GC), were done by gastroscopy and pathology. The differences of clinical characteristics among these diseases were analyzed. Results The FD patients accounted for 7.58% (376/4962) with female in predominant (P = 0.000). The patient with CEG, GU, DU or GC accounted for 29.99% (1488/4962), 1.89% (94/4962),4.25% (211/4962) or 4.57% (227/4962), respectively, all with male in predominant (P<0.05). Further analysis indicated that the age of onset between patients with FD and DU was no difference, but was younger than those with other three diseases (P<0.05). The incidence of early satiation and postprandial in FD patients were higher than those in other patients (P<0.05). The incidence of belching, nausea and vomiting showed no difference among these patients(P>0.05). According to Rome Ⅲ criteria, the symptoms of epigastric pain, early satiation, postprandial fullness and epigastric burning had higher sensitivity and specificity (except epigastric burning)in diagnosing FD (P<0.05), with highest Youden index in epigastric pain (0.42) and postprandial fullness (0.46). Conclusion Rome Ⅲ criteria has high specificity and sensitivity in diagnosing FD, and also has an important value in differentiate FD from other organic diseases.

Trichinella spiralis infection in rodents is a well-known model of intestinal inflammation associated with hypermotility. The aim of the study was to use this experimental model to elucidate if Th17 cells are involved in the development of gastrointestinal hypermotility. Colonic smooth muscle contractility was investigated in response to acetylcholine. The levels of IL-17, IL-23 and TGF-beta1 in colon were measured by Western blotting. Flow cytometric detection of intracellular IFN-gamma/IL-4/IL-17 cytokine production was used to analyze the proportions of CD4+ T cells subsets in colon. Our results showed that colonic muscle contractility was increased 2 weeks post infection (PI) and stayed high 12 weeks PI when no discernible inflammation was present in the gut. The proportion of Th17 cells and the expression of IL-17 were up-regulated in colon 2 weeks PI and returned to normal 8 weeks PI. The content of IL-17 was correlated with the colonic smooth muscle hypercontracility 2 weeks PI. Meanwhile, TGF-beta1 was increased 2 weeks PI, while IL-23 was normal. Our results suggest that Th17 cells affect the colonic muscle contractility in mice infected with Trichinella spiralis at intestine stage but not at muscle stage and the effect of Th17 cells on muscle contractility might be induced by TGF-beta1. Other cytokines might be involved in the hypercontracility of colonic smooth muscle at muscle stage.

Objective To analyze the changes of proportion of Th1/Th2/Th17 cells in colonic mucosa and peripheral blood in pathogenesis of ulcerative colitis (UC) and its significance. Methods Twenty patients with UC were enrolled according to the criterion established in Jinan in 2007 and 16 patients were served as controls. The phenotypes of the colonic mucosa and peripheral blood were analysis by using flow cytometry. The variation of proportion of Th1/Th2/Th17 in colonic lamina propria mononuclear cells (cLPMCs) and peripheral blood mononuclear cells (PBMCs) were compared between two groups. Results The proportion of Th17 cell in cLPMCs was increased in UC group compared with controls [3.75% (6.93%)vs. 1.25 (3.70%), P<0.05], whereas it was 1.40%(2.15%) in UC group and 0.70%(0.33%) in controls in PBMCs with significant difference (P<0.05). The proportion of Th17 cell in cLPMCs was positively correlated with clinical parameters of the disease (r=0.34, P<0.05). No difference was found in proportion of Th1 or Th2 cells in cLPMCs or PBMCs between UC group and controls. Conclusions Among three helper T cells, Th17 cell in UC patients is predominant both in colonic mucosa and peripheral blood, which can be used as an effective target for treatment.
