AIM: To compare the impacts of adriamycin(ADM) intermittent and continuous heat infusion on respiration, heart rate and temperature of the rabbit as well as the concentration of ADM in VX-2 tumor for the verification of the safety and effectiveness of intermittent heat infusion through VX-2 transplanted tumor model in rabbit liver.METHODS: VX-2 tumor models were established respectively in the thighs of 30 New Zealand rabbits. All 30 rabbits were randomly allocated into three groups with 10 rabbits each. After catheterizing into femoral artery, which was demonstrated as the supply artery of tumors by digital subtraction angiography(DSA), animals in three groups were infused with 100 mL saline at normal temperature and ADM, 100 mL saline at 60 ℃ and ADM continuously and 100 mL saline at 60 ℃ and ADM intermittently respectively. During infusion, the 43 ℃ to 45 ℃ lasting time in the tumor tissues of the two 60 ℃ groups was measured. After infusion, the respiration(time/minute), heart rate(beats/minute) and temperature(℃ )of the rabbits in each group as well as the concentrations of ADM in tumor tissue were measured immediately.RESULTS: The concentration of ADM was (7. 1 ± 2.2) mg/L in normal temperature infusion group, (17.2 ± 1.6) mg/L in 60 ℃ continuous infusion group and(16.5 ±3.4) in 60 ℃ intermittent infusion group. There were significant differences among three groups( F = 48.95, P = 0. 000), but there was no significant difference between 60 ℃ intermittent infusion group and 60 ℃ continuous infusion group( P > 0. 05). 43℃ to 45 ℃ lasting time was(22.5 ±1.4) minutes in 60 ℃continuous infusion and (24.3±2.4)minutes in 60 ℃intermittent infusion group( F =4.20, P > 0.05) . There were significant differences among three groups in respiration, heart rate and temperature( F = 14. 58, 33.07, 10.00, P < 0.01), but there was no significant difference in the respiration, heart rate and temperature between 60℃ intermittent infusion and normal temperature infusion group ( P > 0. 05).CONCLUSION: Intermittent thermochemotherapy is a more effective and safe interventional thermochemotherapy method compared with continuous heat infusion.

BACKGROUND:J2 takes functional domain (MHC CD4-D1/) of complex conjugate of CD4 molecule and MHC class II molecule as a target, and is a smal molecule compound obtained by computer screening from a chemical data containing hundreds of thousands of organic compounds. In the previous study, J2 was used in mouse models of skin transplantation and keratoplasty by oral and intraperitoneal injection. Results verified that J2 could prolong the survival time of grafts, and suppress occurrence of rejection. To better play the role of a drug targeting and to reduce systemic toxicity, J2 wil be further utilized in local treatment of keratoplasty rejection. OBJECTIVE:To investigate the inhibitory effect of new immunosuppressive agent J2 on CD4+ and CD8+T cel immune functions in rat models receiving alogenic penetrating keratoplasty. METHODS:Alogeneic penetrating keratoplasty model was established using the adult female Wistar rats as donors and Sprague-Dawley rats as recipients. Group A: normal Sprague-Dawley rats were injected with 0.05 mL placebo subconjunctivaly. Surgery rats were randomly divided into three groups. Group B: alograft rats were injected with 0.05 mL placebo subconjunctivaly after autologous keratoplasty. Group C: alograft rats were injected with 0.05 mL placebo subconjunctivaly. Group D: alograft rats were injected with 1% J2-nanosuspension 0.05 mL subconjunctivaly. The distribution of T cel subsets in peripheral blood was detected using flow cytometry at 3 days, 1, 2 and 3 weeks after transplantation and compared among groups. RESULTS AND CONCLUSION: There was no significant difference in total CD3+ T cels, CD4+ T cels, CD8+ T cels and CD4+/CD8+ in peripheral blood lymphocytes in group B at various time points. At 3 days and 1 week after surgery in group C, no significant difference in total CD3+ T cels, CD4+ T cels and CD8+ T cels was detected. At 1 and 2 weeks, the number of total CD3+ T cels, CD4+ T cels and CD8+ T cels increased, showing significant differences (P < 0.05). In group D, no significant hyperplasy was found in CD4+ T cels and CD8+ T cels at 1 and 2 weeks. The horizontal comparison of the same time point: the total CD3+ T lymphocytes of group D was significantly less than group C at 3 days, 1 and 2 weeks after operation (P < 0.05), whereas there was no significant difference at 3 weeks between the group D and group C. The number of CD4+ T lymphocytes in group D was less than in group C at 3 days and 1 week, but with no significant difference. The ratio of CD4+/CD8+ had no significant difference in group D compared with group C at 3 days, 1 and 3 weeks. J2 inhibits T lymphocyte proliferation and then inhibits T cel-mediated corneal alograft rejection.
