ObjectiveTo investigate the effect of Tongxinluo by the dynamic changes of the expression of matrix metalloproteinase-9(MMP-9) on local cerebral ischemic-reperfusion injury in rats.MethodsMale Wistar rats were randomly divided into sham-operated control group, normal saline control groups (24-hour and 5-day) and Tongxinluo treatment groups(24-hour and 5-day). Animals in the latter four groups were subjected to focal ischemia by filament occlusion of the middle cerebral artery for 90 min. At the different end point, the expression of MMP-9 were assayed using immunohistochemistry staining method. ResultsCompared with the control groups, the expressions of MMP-9 were significantly decreased in both 24-hour and 5-day Tongxinluo treatment groups(P<0.05).ConclusionThe protective effects of Tongxinluo on cerebral ischemia reperfusion injury may be mediated by pharmacological inhibition of MMP-9 activity.The protective effects of Tongxinluo on cerebral ischemia reperfusion injury may be mediated by pharmacological inhibition of MMP-9 activity.

Objective:To investigate the safety and feasibility of hepatectomy in the treatment of hepatic alveolar echinococcosis with secondary cavernous transformation of the portal vein.Methods:The clinical data of 7 patients undergoing surgery at the First Affiliated Hospital of Xinjiang Medical University from Jan 2010 to Dec 2019 were retrospectively analyzed.Results:There were 1 case of cavernous type Ⅰ transformation of the portal vein and 6 cases of type Ⅱ. All patients underwent partial hepatectomy. The average operation time was (9.24±4.09) h. Two patients underwent resection of cavernous segment of portal vein and reconstruction by graft, Albendazole was taken orally for 2 years after discharge. Anticoagulants were taken orally in patients with artificial vascular reconstruction. No recurrence and vascular complications were found. Five patients underwent palliative resection without resection of the cavernous segment of the portal vein. During the follow-up, cavernous transformation of the portal vein progressed in 3 patients, 2 of them esophageal varices rupture and bleeding.Conclusion:Radical hepatectomy and revascularization are the first choice for the treatment of hepatic alveolar echinococcosis complicated with secondary cavernous transformation of portal vein the result was fair.

Lysine acetylation is one of the major post-translational modifications and plays critical roles in regulating gene expression and protein function. Histone deacetylases (HDACs) are responsible for the removal of acetyl groups from the lysines of both histone and non-histone proteins. The RPD3 family is the most widely studied HDACs. This article summarizes the regulatory mechanisms of Arabidopsis RPD3 family in several growth and development processes, which provide a reference for studying the mechanisms of RPD3 family members in regulating plant development. Moreover, this review may provide ideas and clues for exploring the functions of other members of HDACs family.
