We construct both the scalar-diquark-scalar-diquark-antiquark type and axialvector-diquark-axialvector-diquark-antiquark type interpolating currents to study the charmed pentaquark:states suscu with J^(p)=1/2^(±).We employ the QCD sum rules to investigate the masses and pole residues of the charmed pentaquark states by taking into account the vacuum condensates up to dimension 13 in the operator product *** calculation results indicate that the scalar-diquark-scalar-diquark-antiquark type and axialvector-diquark-axialvector-diquark-antiquark type charmed pentaquark states suscu with J^(p)=1/2^(-) can be possible candidates of the excited states observed in the LHCb collaboration.

Effects of a Regional Chinese Diet and Its Vitamin Supplementation on Proliferation of Human Esophageal Cancer Cell Lines

引用

Biomedical and Environmental Sciences 2008年第5期21卷 442-448页

作者： yan JIANG hui-ZHANG DU WEN-YI ZHU hui-juan XIAO AND CHENG-YU HUANG Department of Nutrition and Food Hygiene West China School of Public Health Sichuan University Chengdu 610041 Sichuan China anting Cancer Research Institute Yanting 621600 Sichuan China College of Life Science and Technology Xinjiang Ilniversity llrumchi 830046 Xinjiang China

Objective To study the effects of a local diet popular in yanling region （YT diet） on the proliferation of two human cell lines （Eca-109 esophageal squamous cell carcinoma line and HL7702 normal liver epithelial cell line） in rats by a sero-physiological approach. Methods Male SD rats were divided into six groups and fed respectively with a conventional diet and the YT diet （one of the five experimental diets） supplemented with two vitamin mixtures （Mix.1： vitamins A, E, and folic acid; Mix.2：mix.1 plus riboflavin and vitamin C） at two different doses. On the 30th day, sera were collected from the rats and added into a medium for cell culture, with 10% FBS used as a serum control. The effects were assessed by MTT assay, DNA synthesis and flow cytometry assays. Results Compared with the control, the sera from rats fed with the YT diet significantly promoted the proliferation of Eca-109 cells, which was, however, reversed by the supplementation with two vitamin mixtures at high doses. Surprisingly, the same treatment produced contrary effects on HL7702 cells as compared with Eca-109 cells. Conclusion The sera from rats fed with the YT diet could promote the proliferation of human esophageal cancer cell line Eca-109, whereas the sera from those fed with the YT diet supplemented with vitamin mixtures might have inhibitory effects on the proliferation of Eca-109 ceils.
