Methods Forty-eight 12-week-old SD rats were collected. They were randomly divided into 4 groups: blank control group, NaCl control group, PAH 2-week group and PAH 4-week group. After modeling, ultrasound was used to detect relevant parameters. HE and Masson staining were used to observe the distribution of myocardial cells and collagen fibers in the right ventricle. Superoxide dismutase (SOD) activity, reduced glutathione (GSH) and malondialdehyde (MDA) levels were measured, and their correlations with ultrasound parameters were evaluated. Results The ultrasound-related parameters of rats in the PAH group changed significantly and gradually increased.HE and Masson staining showed that cardiac myocytes were enlarged and collagen fibers in myocardial interstices were increased, and it was more obvious in the 4-week group.In the PAH group, the SOD activity and GSH levels were lower, while the MDA levels were higher, and there was a trend of change, and there was a significant correlation with ultrasound parameters. The difference was statistically significant (P<0.05). Conclusion PAH causes changes in the myocardial tissue structure of the rat right ventricle, as well as changes in oxidative stress-related indicators.

Objective To investigate the effect of reversine (REV) on bile duct ligation (BDL) -induced hepatic damage, fibrosis, epithelial-mesenchymal transformation, and ductular reaction in rats. Methods Male Lewis rats were randomly divided into three groups with 5 rats in each group. Bile duct ligation was performed in the BDL group for two weeks. BDL+ REV group was treated with bile duct ligation and intraperitoneal injection of reversine. The control group was Sham operation (Sham). Blood and liver tissue were obtained after 2 weeks. Blood indexes were determined for total albumin, total bilirubin, alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase and γ-glutamyl transpeptidase. Hepatic histopathology was detected by H&E staining. Azan staining was used to detect tissue collagen deposition. Immunohistochemistry was used to detect the expression of α-SMA, desmin, vimentin, cytokeratin, β-catenin and epithelial cell adhesion molecule (EpCAM) protein. Results Bile duct ligation resulted in the decrease of total albumin synthesis in liver, and the increase of total bilirubin, glutamic-oxalacetic transaminase, alkaline phosphatase and γ-glutamyltranspeptidase. The levels of total bilirubin, aspartate transaminase, alkaline phosphatase and γ-glutamyltranspeptidase returned to the normal level with reversine treatment. Reversine could alleviate cholestasis-induced liver fibrosis by downregulating BDL-induced deposition of collagen and α-SMA protein. Reversine inhibited cholestasis-induced epithelial-mesenchymal transformation by significantly reducing BDL-induced desmin and vimentin expression. Reversine could inhibit cholestasis-induced ductular reaction by significantly reducing the expression of CK7 and CK19 positive biliary cells. Inhibition of cholestasis induced ductular reaction by reversine was associated with regulation of β-catenin and EpCAM expression. Conclusion Reversine can alleviate liver damage caused by cholestasis in rats and have a protective effect. Reversine may be a potential treatment that need further investigation.

Objective To observe the expression of tight junction protein in hyperuricemia induced renal damage model in rats and the intervention effect of febuxostat. Methods SD rats were randomly divided into three groups: normal control group, model control group, febuxostat treatment group. Hyperuricemia was induced in rats with oxonic acid per time for three times per day, by gavage and combined with uric acid added in drinking water, while febuxostat were administered by gavage in febuxostat treatment group.The blood of rats were collected to analyse the differences of control, model and treatment group on changes of blood urea nitrogen (BUN), creatinine (Cr), uric acid (UA). Immunohistochemistry was used to assay ZO-1 and occludin protein expression and quantitive real time PCR to detect the expression of ZO-1 and occludin in renal tissue of renal interstitial fibrosis model rats induced by hyperuricemia. Paraffin section of kidney was maked and then performed Masson staining to make sure the model is successful. Results At 6 weeks, the expressions of ZO-1 and occludin in the model group and treatment group were lower than those in the normal group (all P<0.05). The expressions of ZO-1 and occludin in the treatment group were higher than those in the model group (all P<0.05). Compared with the normal group, the RIF index in the model group and treatment group were higher (all P<0.05), and the RIF index in the treatment group was lower than that in the model group and higher than that in the normal group (all P<0.05). Conclusion The downregulated expression of ZO-1 and occludin plays a crucial role during the development of hyperuricemia in renal interstitial fibrosis, and are closely related to UA level and renal function impairment. Febuxostat may improve the expression of tight junction by downregurating UA, reduce renal fuction impairment and play a role in renal protection.
