AIM To evaluate the undifferentiated embryonal sarcoma of liver (UESL) in adults in order to improve its diagnosis and treatment. METHODS Four primary and one recurrent cases of UESL were clinicopathologically evaluated and immunohistochemically investigated with a panel of antibodies using the EnVision+ system. Relevant literature about UESL in adults(More)
AIM To determine the changes of delayed rectifier K(+) currents (I(k)) and inward rectifier K(+) currents (I(k1)) in the ventricular myocytes of guinea pigs during the gradual apoptotic process by the chronic oxidant stress treatment. METHODS H(2)O(2) 50 micromol/L (24 h) was used for inducing apoptosis in the cardiomyocytes culture of neonatal rats and(More)
Six new (1-6) and 19 known monoterpenoid glucosides were isolated from the root bark of Paeonia suffruticosa. The monoterpenoid glucosides 1, 2, 7, 10-19, and 22 exhibited anticomplement effects with CH50 and AP50 values ranging from 0.14 to 2.67 mM and 0.25 to 3.67 mM, respectively. In a mechanistic study, suffrupaeoniflorin A (1) interacted with C1q, C3,(More)
OBJECTIVE To investigate the effects of bisoprolol on glucose metabolism and blood pressure in essential hypertensive patients with type 2 diabetes mellitus. METHODS A total of 92 hypertensive patients with type 2 diabetes on stable antidiabetic therapy with HbAlc less than 7% were recruited. In a randomized, open trial the patients were treated for 12(More)
Acidosis is one of the important deleterious factors during myocardial ischaemia and reperfusion. The ether-a-go-go-related gene, HERG, is a primary target for blockade by many drugs including dofetilide, quinidine and azimilide. While most drugs lose their efficacy against arrhythmias associated with myocardial ischaemia and reperfusion, dofetilide remains(More)
OBJECTIVE To investigate the association of matrix metalloproteinase 9 (MMP-9) gene -1562C/T polymorphism with the pathogenesis and site involved range of aortic dissection in Chinese population. METHODS 142 hypertensive patients with aortic dissection and 130 hypertensive patients without aortic dissection were enrolled. Genomic DNAs were extracted from(More)
microRNAs (miRNAs) are important regulators of tumor development and progression. In this study, we aimed to explore the expression and role of miR-622 in hepatocellular carcinoma (HCC). We found that miR-622 was significantly downregulated in human HCC specimens compared to adjacent noncancerous liver tissues. miR-622 downregulation was significantly(More)
Germ cell tumor (GCT) of the liver is extremely rare. Here, we describe a case of hepatic mixed GCT with significant sarcomatous components and elevated serum alpha-fetoprotein (AFP) in a 34-year-old man. Histopathologically, the tumor was composed of two GCTs components: yolk sac tumor and immature teratoma. The predominant components of immature teratoma(More)
OBJECTIVE To explore gene expression of estrogen receptor (ERalpha, ERbeta) and androgen receptor (AR) in genioglossal muscle (GG) of adult male rats, and to investigate the effects of sex hormones on GG activities, ERalpha, ERbeta and AR expression. METHODS GG samples were collected from 10 healthy adult male rats. Total RNA were extracted and subjected(More)
Sloshing flows in a two-dimensional rigid rectangular tank under specified excitations in the coupled horizontal and vertical modes are simulated by using a higher-order boundary element method BEM . The liquid sloshing is formulated as an initial-boundary-value problem based on the fully nonlinear potential flow theory. And a semi-mixed Eulerian-Lagrangian(More)
