OBJECTIVESTo investigate the cure effect of tumor antigen specific CTL on a model of human hepatocellular carcinoma in nude mice LCI-D20.
METHODSDendritic cells (DCs) were induced from peripheral blood mononuclear cells of healthy people in vitro by using recombinant human granulocyte-macrophage colony stimulating factor (rhGM-CSF) and interleukin-4 (rhIL-4) and were pulsed with tumor antigen from hepatocellular carcinoma cell line MHCC97H. Then tumor antigen specific cytotoxic T lymphocytes (CTLs) were induced. By intraperitoneal injection of tumour antigen specific CTLs into the LCI-D20, the preventive and therapeutic effects of these CTLs to HCC in the LCI-D20 model were assessed. Cytokine-induced killer (CIK) cells and phosphate buffer solution were used as controls at the same time.
RESULTSThe weights of tumors in the tumor antigen specific CTL group, in the CIK cell group and in the blank group were (1.11+/-0.63), (1.12+/-0.36) and (2.68+/-0.53) grams respectively (t = 5.18, t = 6.06, P < 0.01). The amount of blood alpha fetal protein in the tumor antigen specific CTL and CIK groups were (52.1+/-9.7) microg/L and (48.6+/-5.2) microg/L, and was (82.2+/-7.2) microg/L in the blank group (t = 17.26, t = 22.07, P < 0.01 respectively). The metastasis rates in livers were 16.7%, 16.7% and 58.3% in the tumor antigen specific CTL, CIK cell and blank control groups respectively (chi2= 4.44, P < 0.01). The survival time of the mice in the tumor antigen specific CTL group was (79.0+/-5.02) days, (73.3+/-7.0) days in the CIK group, and (52.3+/-5.2) days in the blank group (t = 14.56, t = 17.54, P < 0.01).
CONCLUSIONTumor antigen specific CTLs may prevent metastasis in the LCI-D20 model and prolong the survival time.

OBJECTIVESTo investigate CD3+CD56+ lymphocytes and their subsets in the peripheral blood of chronic hepatitis B patients and to explore the relationship between these cells and the pathogenesis of their diseases.
METHODSBlood samples from 53 chronic hepatitis B patients, 17 from HBV asymptomatic carriers (ASC) and 19 from healthy controls (HC) were collected. CD3+CD56+ lymphocytes were detected by flow cytometry (FCM), then the CD3+CD56+ lymphocytes were gathered to analyze their expressions of CD4, CD8, TCR Valpha24, TCRalpha/beta and TCRgamma/delta.
RESULTSThe number of CD3+CD56+ lymphocytes of chronic hepatitis B patients (7.4+/-4.6%) was more than those of ASC (4.5%+/-3.5%) and healthy controls (4.4%+/-3.7%). The expressions of TCR Valpha24 on CD3+CD56+ lymphocytes showed no significant differences among the three groups, but the expression of TCR Valpha24 on CD3-CD56+ lymphocytes of ASC ( 2.8%+/-1.4% ) was much more than that of the HC (1.7%+/-1.0%). For the subsets analysis, the CD8 and TCRalpha/beta subsets of CD3+CD56+ lymphocytes of chronic hepatitis B (61.9%+/-16.8% and 68.1%+/-16.9%) were significantly higher than those of the HC (49.2%+/-15.6% and 56.4%+/-17.9%), while the TCRgamma/delta subsets of chronic hepatitis B and ASC (29.6%+/-15.4% and 30.5%+/-14.8%) were decreased significantly than those of the HC (41.4%+/-19.4%). On the other hand, the CD8 and TCRalpha/beta subsets of CD3+CD56+ lymphocytes of severe chronic hepatitis B (69.0%+/-14.0% and 76.1%+/-12.9%) and CD8 subsets of moderate chronic hepatitis B patients (66.4%+/-14.9%) were significantly higher than those of the mild chronic hepatitis B patients (51.4%+/-16.2% and 62.1%+/-14.6%).
CONCLUSIONThe pathogenesis of chronic hepatitis B may positively relate to the high expression of CD8 on the CD3+CD56+ lymphocytes.

OBJECTIVETo detect the relationship between chromosomal anomalies and the pathogenesis, development and prognosis of ovarian carcinoma.
METHODSThirty-six specimens of ovarian carcinoma (n=12), ovarian benign tumor (n=12), and normal ovary (n=12) were examined by fluorescence in situ hybridization (FISH).
RESULTSTwelve cases of mutations, including trisomy 8, monosomy 8 or tetraploid 8 chromosomal anomalies, were found in the group of ovarian carcinoma, making up 100% (12/12). Three cases of trisomy 8 chromosomal anomalies were found in the group of ovarian benign tumor, accounting for 25% (3/12). No anomaly was found in the normal group. There were significant differences between the three groups, P<0.001.
CONCLUSIONThe above anomalies of chromosome 8 are significantly associated with the pathogenesis and development of ovarian carcinoma. The anomalies may occur in the early stage of the carcinoma, and may be significantly associated with the pathological differentiation and clinical stage of the case.
