Objective To observe the protective effect of probiotics VSL # 3 on the rats of trinitrobenzene sulphonic acid (TNBS) induced acute colitis, and the effect on the expression of tight junction proteins claudins (claudinl, 2, and 3) in colon mucosa. Methods Rat of colitis model was induced by TNBS one time enema. Since the second day after the model established, 2ml 0.9％ sodium chloride was intragastric administrated into 8 rats each day (TNBS group), 8 rats with 100 mg VSL # 3 (VSL # 3 group ), another 8 rats with 5-aminosalicylic acid (5-ASA) intragastric administration (5-ASA group), and 0.9％ sodium chloride was intragastric administrated daily into 5 no modeling rats as control group. All were treated for 7 days and then sacrificed. Fecal samples were collected for bacterial culturing and detecting the changes of colon bacteria colonies. Disease activity index (DAI was calculated according to diarrhea, hemafecia and weight. The colon tissue was taken for HE staining and the pathological changes were observed under microscope.The changes of myeloperoxidase (MPO) level in colon tissue were examined by enzyme-linked immunosorbent assay (ELISA). The expression and distribution of claudins 1, 2, and 3 in colon tissue was detected by a novel quantum dots immunofluorescence labeling technique. Results Compared with TNBS group,both VSL # 3 and 5-ASA treatment could improve colitis, as well as decreas DAI and colonic MPO level, and lower the inflammatory score of colitis. Compared with control group, the bacteria counting in the colon of colitis rats changed, the expression of Claudins 1, 2, and 3 expression was significantly increased (average density: 66.200±5.737, 71.780±6.670 and 61.300±5. 199,t＝17.237, 27.909and 21.788, all P＜0.01). Compared with TNBS group or 5-ASA group, VSL# 3 could adjust the balance of intestinal bacteria and increase the expression of Claudin 1 and 3 (Claudin 1 : 75. 550 ±8.717, 66.200±5.737 and 67.080±5.401;t＝9.348, 8. 469; all P＜0.05; Claudin-3: 68. 820±7.443, 61.300±5. 199 and 59. 830±5. 930;t＝7. 519, 8. 988, all P＜0.05), however claudin 2 expression was down-regulated (58. 740±6. 457, 71. 780±6. 670 and 66. 870±5. 791; t＝ 13. 033,P＜0.01, t＝8. 123, P＜0. 05). Conclusion Probiotics VSL# 3 may enhance the intestinal mucosal barrier function through changing the claudins expression, and play a role in the relief of inflammatory reaction in acute colitis.

Visual Analogue Scale (VAS) were assessed before and 4 weeks, 8 weeks and 12 weeks after treatment.ResultsThe scores of VAS showed no difference between the two groups before and 4 weeks after the treatment (P＞0.05). The study group improved in VAS 8 weeks and 12 weeks after the treatment compared to the control group (P＜0.01); the overall efficacy rate was higher in the study group than in the control group (P＜0.01).ConclusionExtracorporeal shock wave therapy is effective to treat the pain caused by soft tissue injury.

Objective The purpose of this paper is to study the variations of the bone conduction hearing in the patients with chronic suppurative otitis media complicated by bone conduction deterioration after tympanoplasty and to analyze the relative factors. Methods In 54 cases (61 ears) of decreased bone conduction thresholds associat-ed with chronic suppurative otitis media, reviewed retrospectively were the data before the operation and during the follow-ups from 3 to 27 months. The bone conduction thresholds at 0. 5,1, 2 and 4 kHz were studied in relation to the courses of disease, the complications of cholesteatoma, the operation procedures and the reconstructions of os-sicular chains before and after surgeries. Results Before operation the most obvious hearing loss of bone conduction was found at 4 kHz in 61 ears, while after operation the average bone conduction hearing at the 4 frequencies was improved at different degrees with the most at 2 k Hz. Thirty-two of 61 cases (52.50%) were found to have their hearing improved at least by more than 10 dE at two frequencies without any deterioration at the 4 frequencies. Con-clusion The factors of the duration of disease and complications of cholesteatoma are obviously not related to the improvement of hearing after operation. A patient with reconstruction of ossicular chain is markedly superior to one without the reconstruction in improvement of hearing. When the auditory ossicular chains and functions of the oval and/or round windows are damaged, the bone conduction hearing can be affected accordingly. However the hearing of some cases will be improved after tympanoplasty. Also, the possible improvement is also related to different sur-geries in treating patients with middle ear infections.

Objective To evaluate diagnostic value of Sonoclot in the diagnosis of heat stroke complicated with disseminated intravascular coagulation (DIC). Methods 43 patients with heat stroke and coagulation dysfunction were retrospectively included and divided into 2 groups according to scores by International Society of Thrombosis and Hemostasis (ISTH): DIC dominant group (22 case) and DIC non-dominant group (21case). Regular coagulation tests , routine blood test , D-dimer and Sonoclot tests were performed at admission and their clinical data were compared. Logistic regression analysis was applied to evaluate the relationships between DIC occurrence and Sonoclot parameters. ROC curves were used to evaluate diagnostic value of Sonoclot for the patients with DIC and heat stroke. Results There were no differences in age, sex, central temperature and total hospital stay between the 2 groups except ICU stay, DIC symptoms, outcome, ISTH scores and APACHEⅡscores (P <0.05). ACT and CR correlated with the occurrence of DIC (P < 0.05). The AUC of ACT and ACT combined with CR were 0.854 and 0.877 respectively. The specificity of ACT in predicting DIC was 69.2%with the sensitivity of 90.3%. When combined with CR, both the specificity and the sensitivity were increased to 80.2% and 93.5%, respectively. Conclusions Sonoclot can predict DIC quickly and is effective in the diagnosis of heat stroke patients with DIC.
