To test the hypothesis, neontal rat cadiomyocytes Treat with heat shock(HS,42℃,2h) to induce the expression of HSP70,then teated with 0.5mmol/L H2O2. We first found H2O2 can reduced cadiomyocytes apoptosis and HSP70 only over-expression in the HS group, other two group only express HSP70 a little in the test of expression of HSP70.Then we tested the concentration of Ca2+, the [Ca2+ ] of CON was 192.224+6.654, the [Ca2+ ] of H2O2 group was 290.6918+8.922and the [Ca2+]of HS group was 214.2633+4.484.To further determine how HSP70 repaired the Ca2+ homestasis, we measured calcium transient of each group.
