Purpose:To evaluate the antitumor effects of human cytokine-induced killer (CIK) cells from healthy donors and patients with primary hepatocellular carcinoma (HCC) in vitro and in vivo .Methods:Peripheral blood mononuclear cells (PBMC) from healthy donors and patients were induced to become CIK cells by in vitro incubation. The CIK cells were identified at different intervals by flow cytometry analysis. The cytotoxicity of CIK cells against autologous primary HCC was determined by 51Cr Release Assays. The antitumor activity of the CIK, LAK and PBMC cells were evaluated in Balb/c nude mice bearing BEL-7402liver cancer.Results:The flow cytometry analysis showed that CIK cells from patients with HCC proliferated and expanded more than 300-fold in vitro incubation by day 28;the percentage of CD3+CD56+ cells increased from 0.23% on day 0 to 17.8% on day 21. CIK cells generated from patients with HCC patients possessed a higher antitumor cytotoxic activity on autologous HCC cells in vitro than autologous PBMC. In addition, CIK cells had a stronger suppressive effect on the tumor growth in Balb/c nude mice bearing BEL-7402 tumor than LAK cells (median inhibitory rates 84.7% vs 52.8%, P

Forty five Han individuals were enrolled for the investigation of the polymorphism property of HIV 1 associated SDF 1? in Chinese Han nationality. Four exons of SDF 1? were cloned by PCR amplification using 4 pairs of primers, then sequenced respectively. DNAstar software was employed to analyze the sequencing results. One SNP and one thymidine deletion were identified in the coding region of SDF1 ?. The SNP was G→T at 192 with a frequency of 8.9%, resulting in replacing lysine to asparagine. The thymidine deletion was at 100 (100?T), which caused frame shift from the 34th amino acid and ending at the 59th amino acid. Both of them were discovered for the first time, and their influences on HIV 1 infection and AIDS progression remain to be explored.
