METHODS: A rat model of UC was established by local stimulation of the intestine with supernatant from colonic contents harvested from human UC patients. A total of 40 male Sprague-Dawley rats were randomly divided into the following groups: normal (sham), model (UC), herb-partition moxibustion (HPM-treated), and positive control sulfasalazine (SA-treated). Rats treated with HPM received HPM at acupuncture points ST25 and RN6, once a day for 15 min, for a total of 8 d. Rats in the SA group were perfused with SA twice a day for 8 d. The colonic histopathology was observed by hematoxylin-eosin. The levels of intestinal flora, including Bifidobacterium, Lactobacillus, Escherichia coli (E. coli), and Bacteroides fragilis (B. fragilis), were tested by real-time quantitative polymerase chain reaction to detect bacterial 16S rRNA/DNA in order to determine DNA copy numbers of each specific species. Immunohistochemical assays were used to observe the expression of TNF-α and IL-12 in the rat colons. RESULTS: HPM treatment inhibited immunopathology in colonic tissues of UC rats; the general morphological score and the immunopathological score were significantly decreased in the HPM and SA groups compared with the model group [3.5 (2.0-4.0), 3.0 (1.5-3.5) vs 6.0 (5.5-7.0), P < 0.05 for the general morphological score, and 3.00 (2.00-3.50), 3.00 (2.50-3.50) vs 5.00 (4.50-5.50), P < 0.01 for the immunopathological score]. As measured by DNA copy number, we found that Bifidobacterium and Lactobacillus, which are associated with a healthy colon, were significantly higher in the HPM and SA groups than in the model group (1.395 ± 1.339, 1.461 ± 1.152 vs 0.045 ± 0.036, P < 0.01 for Bifidobacterium, and 0.395 ± 0.325, 0.851 ± 0.651 vs 0.0015 ± 0.0014, P < 0.01 for Lactobacillus). On the other hand, E. coli and B. fragilis, which are as展开更多

This retrospective study aimed to outline the features of clini-cal, high-resolution computed tomography (HRCT) and pulmonary function test (PFT) of PIBO, undergoing maintenance therapy utilizing a triple nebulization treatment and to determine the factors associated with prognosis. Methods Children diagnosed with PIBO were followed up between April 2014 and March 2017. The clinical features after maintenance nebulization treatment for 12 months were thereafter summarized. Results Thirty patients, 21 boys and 9 girls, were enrolled in the study. The median age of patients was 17.4 months, with a range between 3.0 and 33 months. Persistent coughing and wheezing were detected whilst wheezing and crackles were the common manifestations presented. HRCT scans revealed patchy ground and glass opacity, while PFT showed fixed airway obstruction in all patients. Four patients were lost during follow-up. After treatment, the clinical symptoms were improved greatly in all patients (P<0.01). The mean increase in the percentage of TPEF%TE and VPEF%VE were improved greatly (P < 0.01). Images of the HRCT scan indicated marked improvements in 18 patients (81.8%) in comparison with scans obtained pre-treatment. Conclusions Our data suggest a potential role of long-term nebulization treatment of budesonide, terbutaline, ipratropium bromide on PIBO, due to its efficacy as indicated in the improved clinical symptoms, pulmonary functions and CT manifesta-tions identified in the children. New prospective and controlled studies are required to confirm this proposition.展开更多

MAPKs, MEK1/2 [MAPK/extracellular signal-regulated protein kinase (ERK)kinase] and ribosomal S6 kinase (RSK) phosphorylationwere detected in primary cultures of rat hepatocytesin contact in vitro with (1) E. multilocu/aris vesicle fluid(EmF), (2)E. multilocularis-conditioned medium (EmCM).RESULTS: In the liver of AE patients, ERK 1/2 andp38 MAPK were activated and PCNA expression wasincreased, especially in the vicinity of the metacestode.Upon exposure to EmF, p38, c-Jun N-terminal kinase(JNK) and ERK1/2 were also activated in hepatocytesin vitro, as well as MEK1/2 and RSK, in the absenceof any toxic effect. Upon exposure to EmCM, only JNKwas up-regulated.CONCLUSION: Previous studies have demonstratedan influence of the host on the MAPK cascade inE. multilocularis. Our data suggest that the reverse,i.e. parasite-derived signals efficiently acting onMAPK signaling pathways in host liver ceils, is actuallyoperating.展开更多
