Retrospective Analysis of Yangfei TongluoFormula(养肺通络方)in the Adjuvant Treatment of Post-COVID-19 Pulmonary Fibrosis
(养肺通络方) in adjuvant treatment of post-COVID-19 pulmonary fibrosis (PCPF), and to explore the possible mechanism.
Methods
2
Data of sixty patients hospitalized in the PLA General Hospital of Central Theatre Command from January 1st to April 1st, 2020 were retrospectively collected, and were divided into a control group (24 cases) with conventional western medicine , and an observation group (36 cases) with additional
Yangfei Tongluo
Formula,
both for four weeks. The general data of both groups were collected, and lung CT score before and after treatment was assessed; 6-minute walk test (6MWT) was applied to collect data on 6-minute walk distance (6MWD), number of steps, respiratory rate (RR), heart rate (HR) and transcutaneous oxygen saturation (SpO
2
) before and after walking, patient fatigue and dyspnea score. Serum transforming growth factor β1 (TGF-β1) level and signal transduction protein 2 (Smad2), signal transduction protein 3 (Smad3), signal transduction protein 7 (Smad7) transcription levels, and Smad2, Smad3, Smad7 protein expression level after treatment were evaluated.
Results
2
After treatment, the lung CT scores of both groups decreased, and more changes were found in the observation group than in the control group (
P
<0.05). In the observation group, 6MWD and number of steps increased after treatment, and the difference of RR, HR and SpO
2
before and after walking decreased; in the control group, 6MWD increased after treatment, and the difference of RR and SpO
2
changes before and after walking decreased (
P
<0.05). Compared to those in the control group, 6MWD in the observation group increased, while difference of RR, SpO
2
, fatigue and dyspnea score were reduced (
P
<0.05). The level of TGF-β1 decreased after treatment in both groups, and more change was found in the observation group (
P
<0.05). The transcription and protein expression levels of Smad2 and Smad3 were significantly lower in the observation group than those in the control group, while the Smad7 transcription and protein expression level were higher (
P
<0.05).
Conclusion
2
Yangfei Tongluo
Formula
can improve the pulmonary fibrosis degree, and increase exercise tolerance in daily life in PCPF patients, and the mechanism may be related to the inhibition of the TGF-β1/Smad signaling pathway.
