Objective In order to provide the basis for establishment of food allergy models , we compared the differences of sensitivity and alterations of intestinal flora of food allergy models in two strains of mice .Methods Forty 4-5-week old female BALB/c and Kunmimg mice were divided into control group ( n=10) and food allergy goup ( n=30), respectively.Ovalbumin (OVA) was injected to the mice to establish food allergy models .Serum OVA-specific IgE of the mice was assayed by ELISA .The jejunum tissue was examined by pathology with HE staining .The changes of fecal flora were detected by denaturing gradient gel electrophoresis (DGGE).Results (1)Among the sensitized 60 mice, OVA-sIgE levels were significantly increased in 27/30 BALB/c mice and 21/30 KM mice compared with those of control groups(P<0.001).Moreover, there were more evident inflammatory cell infiltration , epithelial cell shedding and cytolysis in the jejunal villi of BALB/c mice than those of KM mice.(2) After food allergy modeling, there were significant changes of intestinal flora in the BALB/c mice (P<0.001), while only significant change of evenness was found in the KM mice (P<0.05).(3)There were changes of abundance , Shannon index and evenness of intestinal flora in the model groups of BALB/c and KM mice.Conclusions BALB/c mice are more sensitive to OVA allergy than KM mice .The composition of intestinal flora is different among different strains of mice .The changes of intestinal flora after OVA challenge in BALB /c mice are more obvious than those in KM mice .

AIM:To investigate the possible mechanism of magnolol on the damage of PC12 cell induced by the addition of 6-OHDA placed in an incubator for 24 h with rat's pheochromocytoma cell of adrenal medulla in the absence and presence of magnolol. METHODS:Cell viability was measured by MTT method. Reactive oxygen species (ROS) and aspartate-specific cysteine proteases-3 (Caspase-3) concentration(s) were assayed by fluorescence spectrophotometer. RESULTS:Cell activity declined sharply by the addition of 6-OHDA at concentration of 100 ?mol/L,the pre-treatment of magnolol(0.1~10 ?mol/L)could significantly increase the PC12 cell activity and prevent the increased ROS and caspase-3. CONCLUSION:Magnolol may protect the cell trauma induced by 6-OHDA,and the mechanism is related to inhibiting the 6-OHDA-induced elevation in intracellular ROS levels and reducing the caspase-3 activity.

Objective To discuss the value of high resolution MRI in the evaluation of small intralabyrinthine lesions with the symptom of vertigo. Methods We retrospectively analyzed the imaging examination techniques and imaging finding of 13 cases of labyrinthine hemorrhage or exudate and 6 cases of intralabyrinthine schwannoma (ILS) with the symptom of vertigo. Two cases of labyrinthine hemorrhage or exudate and 3 cases of ILS underwent temporal bone high resolution CT(HRCT) scan and all the 19 patients received highresolution MR examination. Patients of labyrinthine hemorrhage or exudate received fluid?attenuated inversion recovery (FLAIR)T2WI in addition to routine pre?contrast temporal bone MR. Pre?and post?contrast MR of the temporal bone were performed on the ILS patients. In particular, 3 ILS cases received three?dimensional sampling perfection with application?optimized contrasts by using different flip angle evolutions (3D?SPACE) sequence. Results There was no abnormal finding on HRCT of the inner ear of the 2 labyrinthine hemorrhage cases. On T1WI, regions of mild increased signal intensity of the labyrinth of affected side could be spotted in 7 patients whereas no abnormal signal intensity was found in the other 6 patients. On T2WI, all the 13 labyrinthine hemorrhage or exudate cases had no abnormal finding in the inner ear. On FLAIR T2WI sequence, regions of increased signal intensity of the labyrinth of affected side could be found in all the 13 cases. Thress ILS patients that received HRCT scan showed no valuable finding. On T1WI, no abnormal signal intensity was found in the labyrinth of the 6 patients. On T2WI, regions of decreased signal intensity of the labyrinth could be found in only 3 patients. All the 3 cases that received 3D?SPACE sequence appeared as a filling defect in the high?signal labyrinth clearly while 2 of the 3 lesions could not be found on T2WI. After Gadolinium administration, all the 6 ILSs were obviously enhancing. Conclusions High resolution MRI is valuable in the diagnosis of labyrinthine hemorrhage or exudate and ILS. The use of FLAIR T2WI sequence can help us to find labyrinthine hemorrhage or exudate more sensitively. The use of 3D?SPACE sequence can help us to detect and diagnose small intralabyrinthine lesions.

This study was aimed to observe the influence ofQing-Chang Hua-Shi Recipe (QHR) on IL-6trans-signaling in experimental colitis mice, in order to initially explore the possible mechanisms of QHR for ulcerative colitis (UC). TNBS/ethanol was used in the establishment of colitis mice model. After intervention of medication, ELISA was used in the detection of soluble Interleukin-6 receptor (sIL-6R). Real-time PCR was used to detect the mRNA expression level of IL-6 and glycoprotein 130 (gp130). Western blot was used in the observation of protein expression of IL-6 and gp130 in the colonic mucosa. The results showed that the level of sIL-6R, the mRNA and protein expression of IL-6 and gp130 in the model group were significantly higher than that in the control group. QHR was able to reduce the sIL-6R level (P < 0.01), decreased the mRNA and protein expression of IL-6 and gp130 (P < 0.01) in the colon tissues among experimental colitis mice. It was concluded that QHR had good anti-inflammatory effects on experimental colitis mice. It might be associated with influencing IL-6trans-signaling.
