Objective To transfect the recombinant mIL-28A adenovirus vector into lung adenocarcinoma cell line LA795 and research its anticancer activity. Methods Transfected the constructed mouse IL-28(mIL-28) recombinant adenovirus vector into LA795 cell line, detected with PCR, immunocytal fluorescence, Tunel, Annexin V and MTT. Results Transfected with rAd-mlL-28A into the LA795 cells, mIL-28A gene expression products mRNA increased obviously, IL-28 expression was detected in cells obviously,apoptosis cell number increased, and the growth of LA795 cells transfected with rAd-mIL-28A were inhibited obviously. Conclusion The recombinant miL-28A adenovirus vector we have constructed, which expresses IL-28 when transfected to lung adenocarcinoma cell line LA795, inhibits growth of carcinoma cell to some extent, and may work by promoting the apoptosis of cancer cells.

OBJECTIVETo explore the possible genetic model of psoriasis vulgaris.
METHODSThe complex segregation analysis and heritability calculation were performed with the aid of Penrose method, Falconer regression method and SAGE-REGTL program.
RESULTSIt was found that in 1043 patients with psoriasis vulgaris, 305 patients (29.24%) have the family history of psoriasis, and 738 patients have not the family history. A ratio of s/q approached 1/(square root of q) with Penrose method, and the heritability values of psoriasis in the first-degree and second-degree relatives were 67.04%, 46.6% respectively. By complex segregation analysis, Mendelian, non-major-gene model and environment model were rejected for psoriasis.
CONCLUSIONThe results suggest that psoriasis follows a pattern of polygenetic or multifactorial inheritance rather than single-gene inheritance.
