ABSTRACT
Hereditary leiomyomatosis and renal cell cancer (HLRCC) syndrome is a rare hereditary disease and characterized by cutaneous leiomyoma, uterine leiomyoma and/or renal cell carcinoma, but rarely associated with vena cava embolism. We treated 1 case of HLRCC syndrome patients with inferior vena cava tumor emboli (Mayo grade Ⅳ), confirmed after genetic testing, the patient and her family refused further treatment. The patient died after two months of follow-up after discharge.
ABSTRACT
Metastatic seminal vesicle carcinoma is rare in clinic. The case of renal clear cell carcinoma metastasis to the seminal vesicle gland is more rare, which is difficult to be identified with bladder, prostate and colorectal tumors. In November 2017, 1 case of renal clear cell carcinoma metastasis to the left side of the seminal vesicle gland was admitted in our hospital.Laparoscopy seminal vesicle metastasis tumor resection was performed. Regular bladder irrigation and sunitib oral intake were conducted. No evidence of local recurrence was found within 19 months follow-up.

ABSTRACT
Interferon induced transmembrane protein (IFITM is a recently discovered antiviral protein family in the cell,which inhibit many with or without coated virus replication to have antiviral effects.At the same time,some recent studies show that IFITM3 plays an important role in migration of a variety of human tumor cells and stem cells.While the mechanism in human tumor occurrence,development and diffusion transfer of IFITM3 is still unclear.This paper is aim to summarize the research progress and direction of IFITM3 protein in human tumors.
ABSTRACT
Objective To investigate the effects of Krüppel like factor 4 (KLF4)on matrix metalloproteinase 9 (MMP9)ex-pression in hepatocellular carcinoma(HCC).Methods A total of 50 primary hepatocellular carcinoma samples and their correspond-ing adjacent tissues specimens were collected.The expression of KLF4 and MMP9 were detected by IHC,Western blot and qRT-PCR.After KLF4 gene was transfected into hepatocellular carcinoma cell line (HepG2 cell line),the expressions of KLF4 and MMP9 were conformed by qRT-PCR and Western blot.Migration and invasion of HepG2 cell line transfected by KLF4 were detec-ted by wound-healing assay and invasion assay.Results Compared to corresponding adjacent tissues,The expression of KLF4 was significantly lower in HCCs(P <0.05),and MMP9 expression was remarkably higher in HCCs(P <0.05).KLF4 over-expression inhibited the expression of MMP9 on the protein and mRNA levels.Wound-healing assay and invasion assay confirmed that KLF4 regulated cell invasion and migration through regulating MMP9 expression.Conclusion KLF4 showed low expression in HCCs,and MMP9 was overexpressed.Up-regulation of KLF4 could decrease the expression of MMP9 in HepG2 cell line,which inhibited inva-sion and migration.
