Journal of Huazhong University of Science and Technology (Medical Sciences) 2013;33(4):491-495
The underlying mechanism of deguelin regulating the cell cycle in human Burkitt's lymphoma cell line Raji cells in vitro, and the cytotoxicity of deguelin to Raji cells and human peripheral blood monocular cells (PBMCs) were investigated. The effects of deguelin on the growth of Raji cells were studied by 3-(4, 5-dimethyl-2-thiazolyl)-2,5-diphenyl-2H-tetrazolium (MTT) assay. Apoptosis was detected through Hoechst 33258 staining. The effect of deguelin on the cell cycle of Raji cells was studied by a propidium iodide method. The expression levels of cyclin D1, P21 and pRb were examined by using Western blotting. The results showed that the proliferation of Raji cells was inhibited in the deguelin-treated group, with a 24-h IC(50) value of 21.61 nmol/L and a 36-h IC(50) value of 17.07 nmol/L. Proliferation in Raji cells was inhibited significantly by deguelin, while little change was observed in PBMCs. Deguelin induced G(2)/M arrest in Raji cells. The expression of cyclin D1, P21 and pRb was dramatically down-regulated by deguelin in a dose-dependent manner. It was concluded that deguelin could inhibit the proliferation of Raji cells by arresting the cells at G(2)/M phase and inducing the cell apoptosis. Moreover, deguelin selectively induced apoptosis of Raji cells with low toxicity to PBMCs. The antitumor effects of deguelin were related to the down-regulated expression of cyclin D1, P21 and pRb proteins.

The genetic diversity of three Tibetan herbs, i. e., Sang-Di, E-Dewa and Ye-Xingba (Tibetan names), was studied based on the field collection, specimen identification and DNA sequence analysis. Swertia hispidicalyx, Gentiana lhassica and Scrophularia dentata, as the original plants of the three Tibetan herbs, were collected and identified. The regions of ITS, matK, rbcL, rpoC1, trnL(UAA), psbA-trnH, atpB-rbcL, trnS (GCU)-trnG(UCC), rpl20-rps12, trnL(UAA)-trnF(GAA) and nadl 2nd intron were amplified and sequenced. The ITS regions of S. hispidicalyx and S. dentata were cloned and sequenced, and the sequences were classified into different genotypes. All the sequences were analyzed and compared with those of closely related species. Our studies may provide reference for the genetic diversity analysis and molecular identification of the three Tibetan herbs.

Objective To evaluate the clinical usefulness of Treponema pallidum IgM Western blot (TP-IgM-WB) test in the diagnosis of neonatal congenital syphilis. Methods Eight cases of neonatal congenital syphilis, whose mothers were diagnosed as syphilis at different pregnant stages, were tested by TRUST, TPPA, FTA-ABS-19S-IgM and TP-IgM-WB. The results and clinical manifestations were analysed. Results Three of 8 cases presented clinical manifestations of congenital syphilis, including typical cutaneous lesions, syphilitic pneumonia, and multi-system failure. The others were asymptomatic. In all 8 cases TP-IgM-WB was positive. Of them 7 cases FTA-ABS-19S-IgM was positive. Six cases (including 3 symptomatic) were positive to all four tests. One case was positive to FTA-ABS-19S-IgM and TP-IgM-WB, but negative to TRUST and TPPA. One case was negative to FTA-ABS-19S-IgM, but positive to TPPA, TP-IgM-WB and TRUST, and TRUST titer was 4 times as high as her mother. Conclusions In view of its high specificity and sensitivity, TP-IgM-WB could be used as a confirmatory test for the diagnosis of both symptomatic and asymptomatic neonatal congenital syphilis.
