In the article titled “Antiapoptosis and Antifibrosis Effects of Qishen Granules on Heart Failure Rats via Hippo Pathway” [1], there was an error in Section 2.5 “Measurement of Serum Biochemical Markers” of the article body. Section 2.5 “Measurement of Serum Biochemical Markers” should be updated as follows:
Measurement of Serum Biochemical Markers:
At the end of the cardiac function examination, rats were anesthetized with 1% pentobarbital sodium (50 mg/kg) by intraperitoneal injection, and blood samples were collected from the abdominal aorta and centrifuged at 1000 ×g for 20 min to obtain serum.Serum levels of ALD and PIIINP were measured by radioimmunoassay. BNP, ANP, MMP-2, and MMP-9 were detected by enzyme-linked immunosorbent assay following the instructions of kits (Fanke Biological Technology Company, Shanghai, China).
