Abstract: The present invention discloses a extra thick hot rolled H section steel and a production method therefor. The extra thick hot rolled H section steel contains, by mass, the following chemical components: 0.04-0.11% of C, 0.10-0.40% of Si, 0.40-1.00% of Mn, 0.40-1.00% of Cr, 0.10-0.40% of Cu, 0.020-0.060% of Nb, 0.040-0.100% of V, 0.010-0.025% of Ti, 0.010-0.030% of Al, 0.0060-0.0120% of N, not more than 0.015% of P, not more than 0.005% of S, not more than 0.0060% of O, and the balance Fe and trace residual elements, wherein 0.090%?Nb+V+Ti?0.170%, 6.5?(V+Ti)/N?10.5, and 0.30%?CEV?0.48%. The extra thick hot rolled H section steel has a flange thickness of 90 mm-150 mm, has excellent comprehensive mechanical properties, and can well meet the needs for heavy supporting structural parts of high-rise buildings, large squares, bridge structures, etc.

Abstract: The invention relates to the application of a recombinant of adenovirus vector and human tumor suppressor p53 gene expression cassette for producing the medicine for treating proliferative disease. In particular the invention relates to the application of a recombinant of adenovirus vector and human tumor suppressor p53 gene expression cassette for producing the medicine for treating scar.

Abstract: The present invention discloses that recombinant p53 adenovirus can ameliorate the side effects normally associated with chemotherapy and radiotherapy. Administration of recombinant p53 adenovirus is effective in reducing the side effects of cancer therapy on patients, and improving the biochemical parameters of these patients. The invention also discloses that recombinant p53 adenovirus alone can improve the quality of life for cancer patients without being combined with other forms of cancer therapy such as chemotherapy or radiotherapy.
