Ligation of splenic artery(LsA) is used for the treatment of liver cirrhosis with hypersplenism. However, hypersplenism is not significantly improved following LsA treatment in some cases, and there are few reports of retreatment of hypersplenism after LsA. We report the case of a47-year-old man with liver cirrhosis and hypersplenism who underwent LsA treatment, but did not significantly improve. Laboratory tests revealed severe leukocytopeniaand thrombocytopenia. Celiac computed tomography arteriogram and digital subtraction angiography revealed two compensatory arteries connected to the hilar splenic artery from the left gastro-epiploic artery and from the dorsal pancreatic artery. Partial splenic embolization(PsE) was performed through the compensatory arteries. As a result, the patient achieved partial splenic ischemic infarction, and white blood cell and platelet counts rose and remained in the normal range. PsE is an effective therapeutic modality for the retreatment of hypersplenism when other modalities have failed.

Objective:To discuss the expression and significance of vascular endothelial growth factor (VEGF) and p53 expression in rat degenerated intervertebral disc(IVD) ***:A total of 78 even-aged sprague-Dawley(sD) rats(observation group) were chosen to establish a rat IVD degeneration model with anterior limbs and tail-removing *** months after modeling, rats were executed and degenerated IVD tissues were obtained for pathological biopsy so as to observe VEGF and p53 expression ***,IVD tissues from 8 healthy rats were gained for ***:Capillary infiltration was found in 62.8%of cases in observation group. Positive expression of VEGF and p53 was seen in 74.4%and 59.0%of cases respectively with a co-expression rate of 53.8%.VECF and p53 expression in degenerated IVD tissues with capillary infiltration was higher than that in non-infiltration group(Psion:A coordinate expression of VEGF and p53 in rat degenerated IVD tissues is demonstrated,indicating that they are both involved in neovascularization and infiltration,which accelerates IVD degeneration.

AIM： To demonstrate the changes in ultrastructure and histopathology of the cornea in acute corneal alkaline burns after femtosecond laser-assisted deep lamellar keratoplasty.·METHODs： The New Zealand white rabbits treated with alkaline corneal burn were randomized into two groups,Group A（16 eyes） with femtosecond laser-assisted deep lamellar keratoplasty 24 h after burn and Group B（16 eyes）without keratoplasty as controls. All eyes were evaluated with transmission electron microscopy（TEM） at 1, 2, 3,and 4wk follow-up, then all corneas were tested by hematoxylin and eosin staining histology.· REsULTs： The corneal grafts in Group A were transparent, while those in Group B showed corneal stromal edema and loosely arranged collagen fibers. One week after treatment, TEM revealed the intercellular desmosomes in the epithelial layers and intact non-dissolving nuclei in Group A. At week 4, the center of the corneas in Group A was transparent with regularly arranged collagen fibers and fibroblasts in the stroma. In Group B, squamous cells were observed on the corneal surface and some epithelial cells were detached.· CONCLUsION： Femtosecond laser-assisted deep lamellar keratoplasty can suppress inflammatory responses, prevent toxic substance-induced injury to the corneal endothelium and inner tissues with quicker recovery and better visual outcomes.
