Objective To analysis the E protein epitopes of dengue virus type 1-4, Japanese encephalitis virus and yellow fever virus and to distinguish the shared or specific epitopes among them. Methods Bioinformatic software DNAStar was used to analyze the hydrophilicity, flexibility, surface probability and antigenicity of dengue virus type 1-4, Japanese encephalitis virus and yellow fever virus E prtein amino acid sequences. The influence of secondary structure was also considered. Based on the bio-informatic analysis of E protein epitopes, 6 specific epitopes were amplified and inserted into prokaryotic expression vector pMAL-c2x. The vectors was then transferred into E.coli BL21 (DE3) and Rosetta (DE3). Isopropyl-β-D-thiogalactoside (IPTG) was used to induce the expression of gene segments and SDS-PAGE were used identify the expression proteins. The antigenieity was tested, using Western blot. Results 15 shared epitopes and 47 specific epitopes were forecasted by bioinformatic analysis, and 6 specific epitopes from dengue virus type 1-4, Japanese encephalitis virus and yellow fever virus E protein were expressed in E.coli successfully. Two specific antigenic determinant from dengue virus type 1 and dengue virus type 2 were confirmed using Western blot, while the others epitopes shown no antigenic reaction property. Conclusion Two specific antigenic determinant were confirmed, under Western blot.

BACKGROUND/AIMS: Mesenteric afferent nerves (MANs) play a pivotal role in the visceral-nociceptive perception. Inappropriate activation of MANs may be involved in the pathogenesis of post-infectious irritable bowel syndrome (PI-IBS). However, the underlying mechanisms remain unclear. We assessed the effects of mucosal mediators from different bowel segments of guinea pigs with PI-IBS on MAN firing and the role of mast cells. METHODS: PI-IBS was induced in guinea pigs by Trichinella spiralis infection. Inflammation in terminal ileum, proximal and distal colon was scored with hematoxylin-eosin staining, and mast cell infiltration was assessed with immunofluorescence. We determined the effects of supernatant extracted from the mucosa of different bowel segments of PI-IBS on MANs activity, and assessed the role of mast cells in this process. RESULTS: Eight weeks after infection, intestinal inflammation resolved, whereas mast cell numbers increased significantly in terminal ileum and proximal colon (P < 0.05) compared with findings in controls. Mucosal supernatant from different bowel segments of PI-IBS models, but not from controls, significantly enhanced the frequency of MAN firing (terminal ileum 41.01 +/- 7.60 Hz vs. 26.55 +/- 0.67 Hz, P = 0.001; proximal colon 45.90 +/- 11.20 Hz vs. 30.88 +/- 6.92 Hz, P = 0.002; distal colon 48.25 +/- 9.70 Hz vs. 29.47 +/- 6.13 Hz, P < 0.001). In addition, the excitatory effects were inhibited by mast cell stabilizer Nasmil (terminal ileum, 32.71 +/- 2.52 Hz, P = 0.030; proximal colon, 30.94 +/- 4.44 Hz, P = 0.002; distal colon, 27.15 +/- 5.83 Hz, P < 0.001). CONCLUSIONS: Supernatant from the intestinal mucosa of different bowel segments of PI-IBS models markedly enhanced the MAN firing in a mast cell-dependent manner, indicating that mast cell-mediated MAN activation plays an important role in the pathogenesis of PI-IBS.

OBJECTIVETo objectively evaluate the clinical effect of traditional Chinese medicine in treating children's respiratory syncytial viral pneumonia (RSVP) of phlegm-heat blocking Fei syndrome (PHBFS).

METHODSA single-blinded multi-center, blocked, randomized and parallel-controlled method was adopted. The clinical study was carried out on 206 children with RSVP-PHBFS who were assigned to two groups, 108 in the test group treated through intravenous dripping of Qingkailing Injection () in combination of oral intake of Er'tong Qingfei Oral Liquid () and 98 in the control group with intravenous dripping of ribavirin injection in combination with oral intake of potassium guaiacol sulfonate oral liquid, all for 10 days. The clinical efficacy was evaluated and compared at the end of the trial from various aspects by three methods including comprehensive efficacy, post-treatment main symptoms score difference and survival analysis of the main symptoms.

RESULTSAfter treatment, in the test group, 60 patients were cured, 36 markedly alleviated, and 12 improved. In the control group, 41 were cured, 38 markedly alleviated, 18 improved and 1 unchanged. Comparison on the comprehensive efficacy between the two groups shows a better efficacy in the test group (chi(2)=4.4527, P=0.0348). Scores of the main symptoms were lowered after treatment in both groups, the difference was 22.41+/-4.99 scores in the test group and 17.61+/-6.34 scores in the control group, being more significant in the former (t=-5.99, P<0.01). Survival analysis shows that there was significant difference between the two groups in the effect initiating time on such symptoms as fever, cough, copious sputum, shortness of breath, and rales, which was earlier in the test group (P<0.01 or P<0.05).

CONCLUSIONEvaluation of the efficacy of traditional Chinese medicine in treating children with RSVP-PHBFS by using the three methods jointly could better show the objectivity of the evaluation.
