Objective To explore the prophylactic effect of T cell vaccination (TCV) on type 1 diabetes. Methods 6-week-old nondiabetic femele NOD mice were vaccinated intraperitoneally with the attenuated, activated T lymphocytes isolated from the spleen of 4-week-old nondiabetic NOD mice, 18-week-old newly diabetic NOD mice and 32-week-old long-term diabetic NOD mice. The incidence of cyclophosphamide-treated diabetes, inflammatory score of insulitis in NOD mice as well as T lymphocyte subset changes in spleen and thymus were determined after TCV. Results TCV was able to reduce the incidence of cyclophosphamide-treated diabetes, to alleviate insulitis, to increase the percentage of CD8+ T lymphocyte subset in spleen and CD4- CD8+ simple-positive T lymphocyte in thymus, and to decrease the percentage of IL-2R+ T lymphocyte and CD4+/CD8+ rate in spleen. Conclusion TCV may decrease host autoimmunity, which seems related to the changes of T lymphocyte subsets in spleen and thymus and prophylactic effect on diabetes.

Objective To explore if strand breaks of DNA in human early chorionic villus cells in uterus were induced by diagnostic ultrasound and to evaluate the method used for detection of single-stranded breaks and doublestranded breaks in human DNA. Methods 60 normal pregnant women aged 20-30, who underwent artificial abortion during 6-8 weeks of gestation, were randomly divided into 2 experimental groups: All 30 cases were exposed to diagnostic ultrasound in uterus for 10 minutes, and 24 hours later chorionic villi were extracted; the other 30 cases were taken as the control group. Single-stranded DNA and double-stranded DNA in villus cells in all cases were isolated by the alkaline unwinding combined with hydroxylapatite chromatography, and were quantitatively detected using32 P-labeled Alu probe for dot-blotting hybridization. Results There was no significant difference in quantity and percentage in single-stranded DNA and double-stranded DNA between 2 groups (P>0.05). 32 P-Alu probe could only hybridize with human DNA, and could detect DNA isolated from as few as 2.5 × 103 chorionic villus cells and 0.45 ng DNA in human leukocytes. Conclusion The results suggested that there were no DNA strand damages in human chorionic villus cells when the uterus was exposed to diagnostic ultrasound for 10 minutes. The method, 32P-Alu probe for dot-blotting hybridization, was even more specific, sensitive and accurate than conventional approaches.

Background and purpose:As a member of the catenin family, Delta-catenin protein could promote proliferation and invasion of tumor cells, but the accurate mechanism of Delta-catenin promoting cell proliferation is not clear. In the present study, we illustrated that Delta-catenin’s effect on cell apoptosis and their relationship with mitogen-activated protein kinase (MAPK) signaling pathway, and the possible mechanism was also explored for Delta-catenin promoting invasion and proliferation of tumor cells. Methods:The alterations of p38 and c-jun N-terminal rinasel JNK protein activity were detected in SPC and SK lung cancer cell lines with Delta-catenin overexpression or not, by Western blot method. At the same time, the apoptotic number of tumor cells was also examined by FCM method. Furthermore, the number of invasive tumor cells was examined by Matrigel invasive experiment. Results:Compared with untreated group and empty vector group, the activity of p38 protein was unchanged in lung cancer cell lines with Delta-catenin overexpressed (P>0.05), but the activity of JNK protein was decreased signiifcantly (P<0.05),meanwhile, apoptotic proportion of tumor cells were also reduced (P<0.05), and invasive ability of tumor cells was enhanced signiifcantly (P<0.05). Conclusion:Delta-catenin probably decreases apoptosis number of lung cancer cells via inhibiting the activity of JNK pathway, and then promotes invasive ability of tumor cells.
