    There exists a constant value of H(z)H(z) at z=−1z=-1 when in ω\omegaCDM universe with ω>−1\omega > -1, which is independent on other cosmological parameters. We first combine this theoretical H(z)H(z) value with the latest 43 observational H(z)H(z) data (OHD) to perform the model-independent Gaussian Processes (GP) and constrain the Hubble constant. We obtain H0H_0=67.67±3.03 km s−1Mpc−1\pm3.03\ {\rm km\ s^{-1} Mpc^{-1}}, which is in agreement with H0H_0 values from Plank Collaboration (2015) (0.24σ0.24 \sigma tension) but a larger deviation from Riess et al. (2016) (1.60σ1.60 \sigma tension), while H0H_0=71.09\ ±3.71 km s−1Mpc−1\pm3.71\ {\rm km\ s^{-1} Mpc^{-1}} (0.64σ (0.64 \sigma tension) by only using latest 43 OHD. Using this H0H_0 value, we perform χ2\chi^2 statistics with Markov Chain Monte Carlo (MCMC) method to constrain cosmological parameters. We obtain ΩM=0.26±0.02\Omega_M=0.26 \pm 0.02 and ω=−0.85±0.06\omega=-0.85 \pm 0.06 in flat ωCDM\omega CDM model, and ΩM=0.27±0.04,ΩΛ=0.80±0.12\Omega_M=0.27\pm 0.04 , \Omega_\Lambda=0.80 \pm 0.12 and ω=−0.82±0.07\omega=-0.82 \pm 0.07 in non-flat ωCDM\omega CDM model, which are larger than those not using the theoretical H(z)H(z) value
