[Retracted] Efficacy of Xiyanping in the Treatment of Elderly Patients with Chronic Obstructive Pulmonary Disease and Its Effect on the Expression of GDF-15 and HIF-1<i>α</i> in Serum

<div>Comparison of sputum excretion between the two groups. Before therapy, they were similar in the two groups. On the 3rd day after treatment, the sputum excretion of the observation group was higher than that of the control group. On the 7th day after treatment, the sputum excretion of the observation group was lower than that of the control group.</div>
