a Effects of LHQK on bodyweight in mice infected with HCoV-229E. Data are presented as mean ± SD (n = 10 in each group). +: model group vs normal group, ⁺⁺P ≤ 0.01. *: LHQW group vs model group, *P ≤ 0.05, **P ≤ 0.01. ▲: LHQK Low group vs model group, ^▲P ≤ 0.05, ^▲▲P ≤ 0.01. ▼: LHQK Medium group vs model group, ^▼P ≤ 0.05, ^▼▼P ≤ 0.01. #: LHQK High group vs model as mean ± SD (n = 10 in each group). ⁺⁺P ≤ 0.01 vs normal group. *P ≤ 0.05, **P ≤ 0.01 vs model group. b Effects of LHQK on lung index in animals. Date are presented as mean ± SD (n = 10 in each group). ⁺⁺P ≤ 0.01 vs normal control. *P ≤ 0.05, **P ≤ 0.01 vs model control group. c The effect of LHQK on viral HA titer and the effect of LHQK on viral HA titer. Data are presented as mean ± SD (n = 10 in each group). ⁺⁺P ≤ 0.01 vs normal group. *P ≤ 0.05, **P ≤ 0.01 vs model group
