OBJECTIVE: To investigate the genetic polymorphisms of 19 STR Loci in Shandong Han population in order to provide the genetic data for paternity testing. METHODS: The genotypes of 205 unrelated individuals in Shandong Han population were typed by Goldeneye 20A kit to get the allele frequencies and population genetic parameters of 19 STR loci. Four kits, Identifiler kit, SinoFiler kit, PowerPlex 16 kit, and Goldeneye 20A kit, were compared with each other and used in the analysis of a special paternity test case. RESULTS: The population genetic parameters of 19 STR loci in Shandong Han Population were obtained. The cumulative discrimination power (CDP) and cumulative probability of exclusion (CPE) ranked from high to low were Goldeneye 20A kit, SinoFiler kit, PowerPlex 16 kit and Identifiler kit, respectively. As duo case, the result of the real case showed that Identifiler kit had no excluding loci, and none of the SinoFiler kit, PowerPlex 16 kit or Goldeneye 20A kit could exclude fatherhood. CONCLUSION Compared with Identifiler kit, SinoFiler kit, and PowerPlex 16 kit, Goldeneye 20A kit shows the higher efficiency than the others, but is not completely satisfied for duo cases.

OBJECTIVETo analyze the pharmacokinetics of intraperitoneal chemotherapy with mitomycin C (MMC) bound to activated carbon particles.

METHODSA nude mouse model with transplanted human gastric cancer was established. The mice were given MMC by i.v. or intraperitoneal (i.p.) injections, or given i.p. MMC bound to activated carbon particles (MMC-CH). Pharmacokinetic assays were carried out at different time points (0.5, 1, 2, 3, 6, 12 and 24 h) in 7 mice per each time point, to compare the MMC concentrations revealed by the above mentioned methods.

RESULTSThe MMC concentration in peritoneal exudate, omentum and lymph nodes of MMC-CH group was significantly higher than that of MMC solution i.p. group and MMC i.v. group (P < 0.001). On the other hand, the MMC level in serum was significantly lower than that in two control groups (P < 0.001). High MMC level was maintained longer than 24 hours in the MMC-CH group. Intraperitoneal chemotherapy with MMC solution resulted in a low MMC concentration in serum, peritoneal exudates and lymph nodes, and only a transient high level of MMC in the omentum. After i.v. administration, a significantly higher level of MMC concentration occurred in the serum, but only a shortly increased concentration of MMC in the omentum, and lower concentration in peritoneal exudate and lymph nodes as compared with those in the other two groups (P < 0.001).

CONCLUSIONHigh concentration of MMC in peritoneal exudate, omentum and lymph nodes maintained longer than 24 hours and a significantly lower MMC serum concentration can be achieved by administration of intraperitoneal administration of MMC bound to activated carbon particles.

This study was aimed to investigate the effect of cord blood dendritic cells (DCs) on the in vitro proliferation capability, immunophenotype changes, level of secreted cytokines and activity against leukemia cells of the homologous cytokine-induced killer (CIK) cells. DCs and CIK cells were induced from cord blood mononuclear cells. They were co-cultured at the ratio of 1:5, and CIK cells from cord blood or DC-CIK cells from peripheral blood were cultured as controls. Immunophenotypic changes were analyzed by flow cytometry, increased number of cells were counted by trypan-blue staining, the killing activity to leukemia cells was assayed by MTT, the levels of interferon-γ (IFN-γ), tumor necrosis factor-α (TNF-α) and interleukin-12 (IL-12) in the cultured supernatant were detected by ELISA. The results showed that the proliferation capability of cord blood DC-CIK cells was significantly higher than that of cord blood CIK cells and peripheral blood DC-CIK cells (p < 0.05 and p < 0.05). Under the same condition, the rate of double positive cells with CD3(+)CD8(+) and CD3(+)CD56(+) in CIK cells was significantly enhanced by co-culture with cord blood DCs (p < 0.05). The level of IL-12, IFN-γ, and TNF-α in cultured supernatants of cord blood DC-CIK cells increased noticeably on day 3 as compared with CIK cells cultured alone (p < 0.01, p < 0.05, p < 0.05). Within the effector-target ratio range between 2.5:1 to 20:1, the activity of cord blood DC-CIK cells against all subtypes of acute leukemia cells was much higher than that of CIK cells (p < 0.05), and there was no significant difference among all subtypes of acute leukemia cells, which was the same with the killing effect of peripheral blood DC-CIK cells against leukemia cells. It is concluded that the proliferation capability and anti-leukemia effect of the homologous CIK cells can be enhanced by cord blood DCs. The proliferation capability of cord blood DC-CIK cells is stronger than that of peripheral blood DC-CIK cells, but there is no significant differences of cytotoxicity between DCs and CIK cells. As the cord blood is easily gained and does not easily cause a serious graft rejection, the DC-CIK cells should be clinically applied more extensively as novel immune therapy.
