Based on 5.8 × 107 J/ψ events collected by BESII, the mass and full width of ηc, as well as its decay branching ratios to K+K− π+π−, π+π−π+π−, , φφ and pp̄ are measured. Partial Wave Analysis (PWA) of J/ψ → γKK̄ and the study of J/ψ → γγV (V = ρ, φ) are performed. We also reported the measurements of J/ψ → pp̄ and J/ψ → π+π−π0.
