[Role of vasculogenic mimicry and endothelium-dependent vessel in metastasis of laryngeal cancer].

Objective: To investigate the contribution of vasculogenic mimicry (VM) and endothelium-dependent vessel (EDV) to invasion and metastasis of laryngeal squamous cell carcinoma (LSCC).

Methods: A total of 203 cases with LSCC was reviewed and followed up. VM and EDV in LSCC tissues were assessed by double staining with anti-CD31 immunohistochemistry and periodic acid-schiff.

[Relationship between the expression of hypoxia-inducible factor-1alpha and epidermal growth factor receptor and micro vessel density and their clinical significance].

Objective: Analyze the relationship between the expression of hypoxia-inducible factor-1alpha (HIF-1alpha) and epidermal growth factor receptor (EGFR) and CD105 micro vessel density (MVD) and their value in evaluating biologic behavior and prognosis in laryngeal cancer.

Methods: Ninety-one cases of laryngeal cancer were analyzed about their clinical and pathology data. In tumor tissue the expression of HIF-1alpha and EGFR was detected by immunohistochemistry and MVD was marked by CD105.

[Inhibition of quercetin on liver fibrosis due to Schistosoma japonicum infection and on the expression of immediate early gene and metalloproteinase 1 inhibitor in liver tissue of mice].

Quercetin and praziquantel were used to treat mice with hepatic fibrosis due to Schistosoma japonicum infection. Quercetin treatment obviously relieved the degree of hepatic fibrosis, significantly reduced the expression of immediate early gene, tissue inhibitor of metalloproteinase 1 (TIMP 1), types I and III collagen compared to the control. The expression of c-jun mRNA, type I and type III collagen were reduced significantly compared to the group treated with praziquantel, whereas no difference in the expression of c-fos mRNA and TIMP1 between the two groups, indicating that quercetin may have better effect on schistosomal liver fibrosis than praziquantel in the long term.
