Network analysis of HBV‑ and HCV‑induced hepatocellular carcinoma based on Random Forest and Monte Carlo cross‑validation.

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer‑associated mortality worldwide. Hepatitis B virus (HBV) and hepatitis C virus (HCV) are two common risk factors for HCC. The majority of patients with HCC present at an advanced stage and are refractory to therapy.

Extraskeletal myxoid chondrosarcoma: A report of two cases.

Extraskeletal myxoid chondrosarcoma (EMC) is a relatively rare but well-defined neoplasm. This report describes two patients, one with EMC of the buttock and one with EMC of the knee. The two cases presented with large lobed masses and long T1 and T2 signaling identified by magnetic resonance imaging (MRI).

[Analysis of TNFbeta gene microsatellite polymorphism in Graves disease].

The work is to study the microsatellite polymorphism of tumor necrosis factor betagene(TNFc)in Graves disease. The TNFc microsatellite polymorphism in the first intron of tumor necrosis factor betagene was amplified by polymerase chain reaction. The allele frequency and genotype frequency of all samples were analyzed by polyacrylamide gel electrophoresis.
