[Metabolomics study of Berberidis Radix in intervening ulcerative colitis based on UPLC-Q-TOF-MS].

The effect of Tujia medicine Berberidis Radix on endogenous metabolites in the serum and feces of mice with ulcerative colitis(UC) induced by dextran sulfate sodium(DSS) was analyzed by metabolomics technology to explore the metabolic pathway and underlying mechanism of Berberidis Radix in the intervention of UC. The UC model was induced in mice by DSS. Body weight, disease activity index(DAI), and colon length were recorded.

Association of Single-Nucleotide Polymorphisms in Monoubiquitinated FANCD2-DNA Damage Repair Pathway Genes With Breast Cancer in the Chinese Population.

Objective: The aim of the study was to estimate breast cancer risk conferred by individual single-nucleotide polymorphisms of breast cancer susceptibility genes.

Methods: We analyzed the 48 tagging single-nucleotide polymorphisms of 8 breast cancer susceptibility genes involved in the monoubiquitinated FANCD2-DNA damage repair pathway in 734 Chinese women with breast cancer and 672 age-matched healthy controls.

Results: Forty-five tagging single-nucleotide polymorphisms were successfully genotyped by SNPscan, and the call rates for each tagging single-nucleotide polymorphisms were above 98.

Routine Hemostasis and Hemogram Parameters: Valuable Assessments for Coagulation Disorder and Chemotherapy in Cancer Patients.

Background: The clotting system abnormalities are the common complication in cancer patients. The aim of this retrospective study was to evaluate the coagulation state, clinical features, and treatment in cancer patients by routine tests.

Methods: A total of 2328 patients with different types of cancer were classified as the positive group (n = 1419, including 53 patients with thrombosis) and the negative group (n = 909) based on D-dimer (DD) value.

[Effects of soluble egg antigen and adult worm antigen of Schistosoma japonicum on differentiation of effector B cells of mice].

Objective: To observe the differentiation ability of effector B cells induced by soluble egg antigen (SEA) and soluble adult worm antigen (SWAP) of Schistosoma japonicum.

Methods: The mouse spleen mononuclear cells and CDl9+ B cells sorted by beadg were stimulated by SEA, SWAP and lipopolysaccharide (LPS), respectively. The ratios of CD19+ IL-6+ cells and CD19+ IFN-gamma+ cells were analyzed by flow cytometry after 72 hours.

[Land use pattern of Dalian City, Liaoning Province of Northeast China based on CA-Markov model and multi-objective optimization].

Based on the land use/cover maps of 1990, 2000, and 2010, topographic factors, and geographic elements, a CA-Markov model consisting of Markov transition matrix, multi-criteria evaluation, and cellular automata was developed to simulate the change trends of the future land use and landscape patterns of Dalian, Liaoning Province. The future land use pattern of Dalian was optimally allocated by the method of fuzzy multi-objective programming, based on the characters of land use structure, society, economy, and natural environment. The results indicated that in 1990-2010, the rapid development of Dalian showed the characteristics of the continued expansion of urban area and the reduction of cropland and woodland area.

Haplotype analysis of eight genes of the monoubiquitinated FANCD2-DNA damage-repair pathway in breast cancer patients.

Background: Ten genes are associated with increased susceptibility to inherited breast cancer have also been associated with population breast cancer risk, and all are involved directly or indirectly in the monoubiquitinated FANCD2-DNA damage repair pathway. We analyzed 13 haplotype blocks in eight of these genes to estimate the breast cancer risk conferred by individual haplotypes.

Methods: Haplotype blocks were constructed with 48 tag single-nucleotide polymorphisms (tSNPs) identified in eight breast cancer susceptibility genes, TP53, PTEN, CHEK2, ATM, NBS1, RAD50, BRIP1, and PALB2.

Inhibition of renal cancer cell growth by oncolytic adenovirus armed short hairpin RNA targeting hTERT gene.

RNA interference (RNAi) has been proved to be a powerful tool for gene knockdown purpose and holds a great promise for the treatment of cancer. Our previous study demonstrated that the reduction of hTERT expression by means of chemically synthesized siRNAs and shRNAs expressed from plasmid resulted in proliferation inhibition in human renal carcinoma cells. In this study, we constructed a novel oncolytic adenovirus-based shRNA expression system, ZD55-hTERT, and to explore ZD55-hTERT-mediated RNAi for hTERT gene silencing.
