Objective To explore changes of the immune function of red blood cells in gastric disease.Methods RBC C3b receptor rosette(RBCC3bRR)and RBC immune complex rosette(RBCICR)were tested in chronic gastritis group(n =103),duodenal ball ulcer group(n =75)and control group(n =30)to evaluate the immune function of RBC.Results RBCC3bRR were(20.83 ± 5.16)％ in the control group,(16.26 ±5.17)％ in the chronic gastritis group and(13.65 ± 5.19)％ in the duodenal ball ulcer group.RBCICR were respectively(7.63 ± 4.09)％,(10.59 + 4.45)％ and(10.04 ± 4.13)％ in these three groups.RBCC3bRR of chronic gastritis and duodenal ball ulcer were lower than control group(P ＜0.0l),while RBCICR were higher than normal control group(P ＜0.05 and P ＜0.01 respectively).There was no significant difference on RBCC3bRR and RBCICR between HP negative chronic gastritis and HP negative duodenal ball ulcer and between HP positive chronic gastritis and HP positive duodenal ball ulcer(P ＞ 0.05).RBCC3bRR of HP positive chronic gastritis and duodenal ball ulcer was significantly lower than that of HP negative(P ＜ 0.05and P ＜ 0.01 respectively),RBCICR significantly higher than that of HP negative(P ＜ 0.01).After HP eradication,RBCC3bRR of patients with chronic gastritis and duodenal ball ulcer was increased significantly (P＜0.05 and P ＜ 0.01 respectively).RBCICR was significantly lower than before treatment(P ＜ 0.01).Conclusion HP infection,chronic gastritis and duodenal ulcer can decrease the immune function of red blood cells.

We wished to screen the cell line that stably expresses the HPV18E5 protein, and to ascertain the influence of HPV18E5 protein on cell proliferation and the cell cycle. The HPV18E5 gene was amplified by the polymerase chain reaction. Then, the His-tag pSecTag-HPV18E5 eukaryotic expression vector was constructed by digestion ligation and connection. The recombinant plasmid was transfected into Balb/c3T3 cells with lipofectamine, and positive cell lines were screened by a culture medium containing bleomycin. HPV18E5 expression in cells was confirmed by western blotting and immuno-enzymatic methods. The influence of HPV18E5 on cell proliferation and the cell cycle were detected by Cell Counting Kit-8 and flow cytometry, respectively. The pSecTag-HPV18E5 eukaryotic expression vector was constructed. After 21-day selection in a culture medium containing 400 μg/mL bleomycin, stably expressing HPV18E5 protein cells were harvested. Compared with control groups, cell proliferation in HPV18E5 stably expressed cells was obviously increased, as was the S phase in the cell cycle. Our results suggested that HPV18E5 influences cell proliferation and the cell cycle. Our study has laid the foundation of the biologic properties of HPV18E5 protein, which will aid further studies on the mechanism of action of carcinogenesis.
