Objective: To study the effect of benazepril on the expression of nuclear factor E2 related factor 2 (Nrf2), nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4) and reactive oxygen species (ROS) concentration in rats with hepatic fibrosis and to explore the possible antifibrotic mechanism of benazepril. Methods: Twenty-two healthy male Sprague-Dawley rats were randomly divided into 3 groups: control group (6 rats), model group (8 rats) and benazepril treatment group (8 rats). Two rats died during modeling and treatment in the model group and the benazepril treatment group, and a model of hepatic fibrosis induced by carbon tetrachloride (CCL₄) was established. The rats in benazepril group were given benazepril for 8 weeks by gastric gavage. The assessment of liver tissue damage in each group was measured using conventional hematoxylin-eosin and Masson staining. The mRNA level of Nrf2, NOX4 in liver tissue was detected by RT-PCR, and serum ROS concentration was determined by colorimetry. All data were expressed in mean ± standard deviations, and were analyzed using SPSS21.0 statistical software. The data were compared using one-way analysis of variance, and the LSD-t method was used for pairwise comparison between the two groups. The correlation analysis was performed by Spearman’s correlation analysis. Results: In the liver of the model group, with the aggravation of liver fibrosis the expression of Nrf2mRNA, NOX4 mRNA and ROS concentration were higher than control group [(4.01 ± 3.40), (31.78 ± 3.96), (1.82 ± 0.46) μg/ ml vs. (0.12 ± 0.11), (2.03 ± 0.31), (1.56±0.84) μg/ml, P < 0.05]. After benazepril treatment, NOX4 mRNA expression and ROS concentration were decreased than the model group [(15.93 ± 5.01), (0.78 ± 0.44) μg/ml vs. (31.78 ± 3.96), (1.82 ± 0.46) μg /ml, P < 0.05], while Nrf2 mRNA expression was higher than the model group [(6.69 ± 4.86) vs. (4.01 ± 3.40), P < 0.05]. There was a positive correlation between Nrf2 and NOX4, Nrf2 and ROS, and NOX4 and ROS (r = 0.616, 0.411, 0.802, P < 0.05). Conclusion Benazepril may exert an anti-hepatic fibrosis effect by activating Nrf2 expression, or may inhibit the ROS-mediated oxidative stress in response to NOX4.

Objective: To investigate the effects of angiotensin II type 1 receptor antagonist valsartan on leptin, leptin receptor and collagen in rats with hepatic fibrosis. Methods: Thirty-six male wistar rats were randomly divided into control group, model group and drug-treated group, with 12 rats in each group. Liver fibrosis models were made by subcutaneous injection of carbon tetrachloride on the dorsal of the rats, simultaneously gastric gavage with Valsartan and were killed at the end of 8th week. The degree of liver fibrosis was observed by HE and Masson staining. The serum leptin (LP) and TGFβ1 were determined by ELISA. Liver LP mRNA and leptin receptor mRNA (OB-R mRNA) were detected by RT-PCR. Liver LP, OB-R and collagen I were detected by Western blot. The data of multiple groups were analyzed by one-way analysis variance (ANOVA), and linear correlation was performed between serum LP and TGF β1. Results: After the intervention of valsartan, HE and Masson staining showed that the degree of liver fibrosis was significantly reduced. The levels of serum LP and TGFβ1 in the control group were (18.92 ± 7.10) ng/ml and (9.13 ± 1.58) pg/ml respectively, which were significantly lower than those in the model group (46.92 ± 28.54) ng/ml and (16.39 ± 3.56) pg/ml, And (29.27 ± 7.27) ng/ml and (12.24 ± 2.94) pg/ml in the drug-treated group, respectively. The F values were 7.864 and 20.057 respectively. The P values were < 0.05. The differences were statistically significant. The relative expression levels of LP and OB-R mRNA in the control group were 0.35 ± 0.18 and 0.62 ± 0.18, respectively, which were significantly lower than those in the model group (1.79 ± 1.79 and 1.52 ± 1.44, and drug-treated group 0.48 ± 0.34 and 0.75 ± 0.26, respectively), F values = 6.914,3.894, P values were < 0.05, the differences were statistically significant. The relative expression levels of LP, OB-R and collaten I in liver were 0.71 ± 0.13, 0.81 ± 0.11 and 0.76 ± 0.13 in the model group, 0.97 ± 0.06, 1.04 ± 0.06, and 1.05 ± 0.04 respectively in the drug-treated group and 0.74 ± 0.05, 0.93 ± 0.05 and 0.91 ± 0.05. The F values were 15.425, 13.757 and 19.130 respectively in three groups (P < 0.001), the difference was statistically significant. Conclusion Valsartan, an angiotensin II type 1 receptor antagonist, can reduce the expression of leptin and leptin receptor, reduce the production of TGFβ1 and collaten I, and play an anti-hepatic fibrosis effect.

OBJECTIVE:To investigate the clinical efficacy and safety of Cinobufacin capsules combined with radiotherapy in the treatment of median and advanced nasopharyngeal carcinoma. METHODS:Ninety-five patients with median and advanced naso-pharyngeal carcinoma in cancer center of our hospital during 2011-2012 were analyzed retrospectively,and then divided into con-trol group (57 cases) and observation group (38 cases) according to therapy plan. Control group received radiotherapy alone, while observation group was additionally given Cinobufacin capsule 0.5 g,tid,till the end of radiotherapy. A treatment course last-ed for 4 weeks. The prolonged radiotherapy were compared between 2 groups. Clinical response rate was observed in 2 group,and 1-year and 3-year survival rate and the occurrence of ADR were followed up. RESULTS:The proportion of prolonged radiotherapy was 89.47% in control group,which was significantly higher than 52.63% of observation group,with statistical significance(P<0.05). At the end of therapy and one month after therapy,clinical total response rates of observation group were 81.58% and 63.16%,which were significantly higher than 70.18% and 45.61% of control group,with statistical significance (P<0.05). The incidence of white blood cell lowering,hemoglobin lowering,local side effect of radiotherapy, nasopharyngeal dysphagia/odyno-phagia in observation group were significantly lower than in control group,with statistical significance (P<0.05). There was no statistical significance in survival rate between 2 groups in 1st-year and 3rd-year follow-up (P>0.05). CONCLUSIONS:Cinobu-facin capsule combined with radiotherapy can significantly relieve the side effects of radiotherapy in median and advanced nasopha-ryngeal carcinoma patients.
