BACKGROUND Portal hypertension (PHT) requires invasive measures to prevent rupture and bleeding of esophagogastric varices; however, the long-term results of subtotal splenectomy plus fixation of the retrosternal omentum majus (SSFROM) have not been reported. Specifically, the advantages and disadvantages of surgery that preserves the spleen and the(More)
The purpose of this study is to describe the infiltration of mast cells as well as T and B cells in the walls of thrombotic varicose great saphenous veins. Sections were obtained from venous segments of patients with varicose veins and stained with toluidine blue for mast cells, while immunohistochemistry for T cells (using CD45RO antibody) and B cells(More)
BACKGROUND Following splenomegaly due to portal hypertension, pathologic characteristics include passive congestion and lymphoplasia. High venous pressure and hemodynamics can result in vascular proliferation and lymphoplasia, and promote splenic microcirculation and functional changes. The aim of this study was to determine the changes in penicillar(More)
BACKGROUND In recent years, the spleen has become to be recognized as the "control center" of the immune-metabolic-endocrine network. However, It is controversial that splenomegaly due to portal hypertension is treated by subtotal splenectomy. The aim of this study was to evaluate the distribution of fibrous tissue, morphology of cells as well as splenic(More)
INTRODUCTION Programmed cell death plays a critical role in various physiological processes. In the present study, we investigated its possible pathogenic role in primary varicose veins. We studied histological changes in surgical specimens from thrombophlebitic saphenous veins. In thrombophlebitic saphenous, varicose, and healthy veins, we also determined(More)
The existing irrigation schedule of most rice-growing areas in Jilin Province is not in full compliance with the Water Requirements Law of the rice; these discrepancies affect the yield of rice to some extent. Thus, research on rice water regulations and selection of an appropriate water production function model (WPFM) is very important. In this study,(More)
Sulfur mustard (SM) is believed to be a major threat to civilian populations because of the persistent asymmetric threat by nonstate actors, such as terrorist groups, the ease of synthesis and handling, and the risk of theft from stockpiles. The purpose of this study was to establish mechanisms of acute tracheal injury in rats induced by SM using(More)
The spleen is thought to be central in regulating the immune system, a metabolic asset involved in endocrine function. Overwhelming postsplenectomy infection leads to a mortality rate of up to 50%. However, there is still controversy on performing subtotal splenectomy as treatment of splenomegaly due to portal hypertension in cirrhotic patients. In the(More)
OBJECTIVE Varicose veins (VVs) are a common disorder of venous dilation and tortuosity, but the underlying mechanism is unclear. The functional integrity and phenotypic differences of VVs are also unclear. This study tested the hypothesis that phenotypic and functional differences exist between smooth muscle cells (SMCs) derived from VVs and normal veins.(More)
Mediumand long-term runoff forecasting is essential for hydropower generation and water resources coordinated regulation in the Yellow River headwaters region. Climate change has a great impact on runoff within basins, and incorporating different climate information into runoff forecasting can assist in creating longer lead-times in planning periods.
