Clinical Significance of Spleen-Remnant Liver Volume Ratio in Hepatocellular Carcinoma Surgery.

The objective of this study was to explore the value of spleen-remnant liver volume ratio for hepatocellular carcinoma surgery and liver reserve assessment. Spleen-remnant liver volume ratio postoperation was measured with imageological methods and water displacement, and the liver function postoperation and hospital stay of patients with different spleen-remnant liver volume ratios were compared. Spleen-remnant liver volume ratio was closely related to liver function assessment postoperation.

Correlation between miR-126 expression and DNA hypomethylation of CD4+ T cells in rheumatoid arthritis patients.

It has been known that the occurrence of rheumatoid arthritis (RA) was closely correlated with DNA hypomethylation in CD4+ T cells, in which DNA methyltransferase plays a certain role. This study therefore investigated the effect of miR-126 on CD4+ T cell subgroup in RA patients and the alternation of DNA hypomethylation, in an attempt to provide new sights into the pathogenesis and treatment of RA. CD4+ T cells separated from RA patients were transfected with miRNA (miR)-126 expression vector or miR-126 inhibitor expression vector.

MicroRNA-522 reverses drug resistance of doxorubicin-induced HT29 colon cancer cell by targeting ABCB5.

MicroRNAs (miRNAs) are small non-coding RNAs, which are important in the development of multidrug resistance in cancer by regulating gene expression at the post‑transcriptional level. The present study investigated the functional effects of miR‑522 in chemoresistant colon cancer cells. The results demonstrated that miR‑522 was significantly downregulated in doxorubicin (DOX) resistant colon cell line, HT29/DOX, compared with the parental HT29 colon cancer cell line.

Upregulation of miR-195 increases the sensitivity of breast cancer cells to Adriamycin treatment through inhibition of Raf-1.

Chemotherapy is an important option for the treatment of advanced breast cancer, but multidrug resistance is one of the major obstacles in the clinical control of breast cancer. The present study investigated the effects of the miR‑195-led gene pathway in the sensitization of breast cancer cells to treatment with the chemotherapeutic drug Adriamycin. Breast cancer cell lines and tissue specimens (obtained from chemotherapy-sensitive or resistant patients) as well as a normal breast cell line were used to assess expression of miR-195, Raf-1, Bcl-2 and P-glycoprotein mRNA and/or mRNA.

CYP2E1 polymorphisms and colorectal cancer risk: a HuGE systematic review and meta-analysis.

Studies investigating the associations between Cytochrome P4502E1 (CYP2E1) polymorphisms and colorectal cancer (CRC) risk report conflicting results. We conducted a meta-analysis to assess the association between CYP2E1 gene Rsa I/Pst I, Dral T/A and 96-bp insertion polymorphisms and CRC susceptibility. Two investigators independently searched the Medline, Embase, CNKI, Wanfang, and Chinese Biomedicine Databases.
