Model rats were induced by DMN for 4 weeks and at final stage were executed. TNF-α mRNA were detected by RT-PCR and the inflammatory necrosis and collagen deposition in hepatic tissue were observed by HE stain and Sirius red stain. The liver functions were determined by automatic biochemical analytic device. The serum marks of liver fibrosis, such as HA, LN and Ⅳ-C were measured with ELISA and RIA. Results: In this study, the rat model of liver fibrosis induced by DMN was successfully constructed. RT-PCR reveals that TNF-α mRNA expression in control group is lower than that of model group. The liver functions of model group were impaired compared with those of the control group (P<0.01). Semi-quantitive analysis revealed that TNF-α/β-actin of normal rats was 0.39±0.12, while 0.93±0.05 of model rats. The concentration of HA (434.44±98.81 vs 252.9±26.59 ng/ml, P<0.01), LN (70.67±6.32 vs 37.90±5.97 ng/ml, P<0.01) and Ⅳ-C (79.39±10.52 vs 21.40±4.17 ng/ml, P<0.01) were significantly increased in the model group as well. Changes of the indexes were similar to the pathological damage of the liver. Conclusion: The results suggested that activation of TNF-α in liver tissues may be the common pathogenic mechanism of liver fibrosis. TNF-α may be a useful index for the diagnosis of hepatic fibrosis which worthies further investigation.展开更多

The differential cross sections, the analyzing powers, and the total cross sections of the intermediate energy proton-160 scattering have been calculated by using the obtained optical potential. The main features of the measured angular distributions of the cross section and the analyzing power can be well described. The calculated total cross sections are in good agreement with the experimental data at energies below 0.7 GeV and underestimate the data about 8% at higher energies.展开更多

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 associated with an inflamed colon, were significantly lower in the HPM and SA groups than in the model group (0.244 ± 0.107, 0.628 ± 0.257 vs 1.691 ± 0.683, P < 0.01 for E. coli, and 0.351 ± 0.181, 0.416 ± 0.329 vs 1.285 ± 1.039, P < 0.01 for B. fragilis). The expression of TNF-α and IL-12 was decreased after HPM and SA treatment as compared to UC model alone (4970.81 ± 959.78, 6635.45 ± 1135.16 vs 12333.81 ± 680.79, P < 0.01 for TNF-α, and 5528.75 ± 1245.72, 7477.38 ± 1259.16 vs 12550.29 ± 1973.30, P < 0.01 for IL-12). CONCLUSION: HPM treatment can regulate intestinal flora and inhibit the expression of TNF-α and IL-12 in the colon tissues of UC rats, indicating that HPM can improve colonic immune response.展开更多

Dq = 3.0 Gy. n=7.7 for X-rays.Incidence of α particles or X-rays induced cell transformation was dose-dependant.α particles were more efficient in inducing cell transformation than that of X-rays. The enhancement of SHE cell transformation by phorbol 12-myristate 13-acetate(PMA) following exposure to α particles of 0. 25-1. 00 Gy was observed.展开更多

Methods： The influences of craniotomy model and bone-abrading model on cerebral microcirculation were compared. The bone-abrading method was used to detect the effects of intracerebroventricular application of 40 μg/kg.bw TNF-a on cerebral venular leakage of fluorescein isothiocyanate （FITC）- albulmin and the rolling and adhesion of leukocytes on venules with fluorescence tracer rhodamine 6G, The therapeutical effects of SAB on TNF-a induced microcirculatory alteration were observed, with continuous intravenous injection of 5 mg/kg.h SAB starting at 20 min before or 20 min after TNF-a administration, respectively, The expressions of CDllb/CD18 and CD62L in leukocytes were measured with flow cytometry, Immunohistochemical staining was also used to detect E-selectin and ICAM-1 expression in endothelial cells, Results： Compared with craniotomy method, the bone-abrading method preserved a higher erythrocyte velocity in cerebral venules and more opening capillaries. TNF-a intervention only caused responses of vascular hyperpermeability and leukocyte roiling on venular walls, without leukocyte adhesion and other hemodynamic changes. Pre- or post-SAB treatment attenuated those responses and suppressed the enhanced expressions of CDII b/CDI8 and CD62L in leukocytes and E-selectin and ICAM-I in endothelial cells induced by TNF-a. Conclusions： The pre- and post-applications of SAB during TNF-a stimulation could suppress adhesive molecular expression and subsequently attenuate the increase of cerebral vascular permeability and leukocyte rolling.展开更多

Methods Seventy healthy SD rats were randomly divided into seven groups, including control group, model group, ＂Zúsānlǐ＂（足三里 ST 36） group, ＂Shàngjùxū＂（上巨虚 ST 37） group, ＂Xiàjùxū＂（下巨虚 ST 39） group, ＂Yánglíngquán＂（阳陵泉 GB 34） group and ＂Chéngjīn＂（承筋 BL 56） group, with five male rats and five female rats in each group. Acute gastric mucosal lesion model was established by applying WRS method. After successful modeling and treatment for ten days, sampling was conducted, gastric mucosal lesion was observed visually and scored, the levels of serum HMGB 1 and gastric tissue TNF-α were detected by ELISA method, and the expression of NF-κB was detected by immunohistochemical method. Results①Compared with the model group, the levels of Ulcers and inflammation（UI） in gastric mucosal and serum HMGB1, and the expression of gastric tissue TNF-α and NF-κB in the four lower he-sea points groups reduced（P〈0.01 or P〈0.05）;② compared with ST 36 group, the levels of gastric mucosal UI and serum HMGB1, and the expression of gastric mucosal TNF-α and NF-κB in other treatment groups increased significantly, and the difference was statistically significant（P〈0.01 or P〈0.05）. Conclusion①Electroacupuncture at relevant lower he-sea points can inhibit the body＇s immune response, relieve inflammatory reaction and reduce mucosal lesion by regulating HMGB 1, TNF-α and NF-κB, so as to realize the intervention and treatment on AGML rats;② the total intervention effect in ST 36 group is superior to that in other groups, indicating partially that there is a relative specificity between ST 36 and stomach.展开更多
