Study on the Mechanism of Qing-Fei-Shen-Shi Decoction on Asthma Based on Integrated 16S rRNA Sequencing and Untargeted Metabolomics.

Qing-Fei-Shen-Shi decoction (QFSS) consists of Prunus armeniaca L., Gypsum Fibrosum, Smilax glabra Roxb., Coix lacryma-jobi L., Benincasa hispida (Thunb.) Cogn., Plantago asiatica L., Pyrrosia lingua (Thunb.) Farw., Houttuynia cordata Thunb., Fritillaria thunbergii Miq., Cicadae Periostracum, and Glycyrrhizae Radix Et Rhizoma Praeparata Cum Melle. QFSS shows significant clinical efficacy in the treatment of asthma. However, the specific mechanism of QFSS on asthma remains unclear. Recently, multiomics techniques are widely used in elucidating the mechanisms of Chinese herbal formulas. The use of multiomics techniques can better illuminate the multicomponents and multitargets of Chinese herbal formulas. In this study, ovalbumin (OVA) was first employed to induce an asthmatic mouse model, followed by a gavage of QFSS. First, we evaluated the therapeutic effects of QFSS on the asthmatic model mice. Second, we investigated the mechanism of QFSS in treating asthma by using an integrated 16S rRNA sequencing technology and untargeted metabolomics. Our results showed that QFSS treatment ameliorated asthma in mice. In addition, QFSS treatment affected the relative abundances of gut microbiota including Lactobacillus, Dubosiella, Lachnospiraceae_NK4A136_group, and Helicobacter. Untargeted metabolomics results showed that QFSS treatment regulated the metabolites such as 2-(acetylamino)-3-[4-(acetylamino) phenyl] acrylic acid, D-raffinose, LysoPC (15 : 1), methyl 10-undecenoate, PE (18 : 1/20 : 4), and D-glucose6-phosphate. These metabolites are associated with arginine and proline metabolism, arginine biosynthesis, pyrimidine metabolism, and glycerophospholipid metabolism. Correlation analysis indicated that arginine and proline metabolism and pyrimidine metabolism metabolic pathways were identified as the common metabolic pathways of 16s rRNA sequencing and untargeted metabolomics. In conclusion, our results showed that QFSS could ameliorate asthma in mice. The possible mechanism of QFSS on asthma may be associated with regulating the gut microbiota and arginine and proline metabolism and pyrimidine metabolism. Our study may be useful for researchers to study the integrative mechanisms of Chinese herbal formulas based on modulating gut microbiota and metabolism.

He-Jie-Shen-Shi Decoction as an Adjuvant Therapy on Severe Coronavirus Disease 2019: A Retrospective Cohort and Potential Mechanistic Study.

Combination therapy using Western and traditional Chinese medicines has shown notable effects on coronavirus disease 2019 (COVID-19). The He-Jie-Shen-Shi decoction (HJSS), composed of Bupleurum chinense DC., Scutellaria baicalensis Georgi, Pinellia ternata (Thunb.) Makino, Glycyrrhiza uralensis Fisch. ex DC., and nine other herbs, has been used to treat severe COVID-19 in clinical practice. The aim of this study was to compare the clinical efficacies of HJSS combination therapy and Western monotherapy against severe COVID-19 and to study the potential action mechanism of HJSS. From February 2020 to March 2020, 81 patients with severe COVID-19 in Wuhan Tongji Hospital were selected for retrospective cohort study. Network pharmacology was conducted to predict the possible mechanism of HJSS on COVID-19-related acute respiratory distress syndrome (ARDS). Targets of active components in HJSS were screened using the Traditional Chinese Medicine Systems Pharmacology (TCMSP) and PharmMapper databases. The targets of COVID-19 and ARDS were obtained from GeneCards and Online Mendelian Inheritance in Man databases. The key targets of HJSS in COVID-19 and ARDS were obtained based on the protein-protein interaction network (PPI). Kyoto Encyclopedia of Genes and Genomes analysis (KEGG) was conducted to predict the pathways related to the targets of HJSS in COVID-19 and ARDS. A "herb-ingredient-target-pathway" network was established using Cytoscape 3.2.7. Results showed that the duration of the negative conversion time of nucleic acid was shorter in patients who received HJSS combination therapy. HJSS combination therapy also relieved fever in patients with severe COVID-19. Network pharmacology analysis identified interleukin (IL) 6, tumor necrosis factor (TNF), vascular endothelial growth factor A (VEGFA), catalase (CAT), mitogen-activated protein kinase (MAPK) 1, tumor protein p53 (TP53), CC-chemokine ligand (CCL2), MAPK3, prostaglandin-endoperoxide synthase 2 (PTGS2), and IL1B as the key targets of HJSS in COVID-19-related ARDS. KEGG analysis suggested that HJSS improved COVID-19-related ARDS by regulating hypoxia-inducible factor (HIF)-1, NOD-like receptor, TNF, T cell receptor, sphingolipid, PI3K-Akt, toll-like receptor, VEGF, FoxO, and MAPK signaling pathways. In conclusion, HJSS can be used as an adjuvant therapy on severe COVID-19. The therapeutic mechanisms may be involved in inhibiting viral replication, inflammatory response, and oxidative stress and alleviating lung injury. Further studies are required to confirm its clinical efficacies and action mechanisms.

Effects of Feiwei granules in the treatment of idiopathic pulmonary fibrosis: a randomized and placebo-controlled trial.

OBJECTIVE: To document the therapeutic effects of Feiwei granules (FGs) for idiopathic pulmonary fibrosis (IPF). METHODS: One hundred cases with IPF were randomized into the treatment group (80) and control group (20). Both groups were given basic treatment with prednisone. The treatment group was given FGs, and the control group was given Jinshuibao capsules (JCs). Treatment lasted for 6 months. The Medical Research Council Dyspnea Scale (MRCDS), the Saint George's Hospital Respiratory Questionnaire (SGHRQ), pulmonary function, the Traditional Chinese Medicine Syndrome Score (TCMSS), 6-min walking test (6MWT) and blood gas analyses were recorded before the study as well as 3 months and 6 months after treatment. RESULTS: FGs showed greater efficacy than the control in certain parameters between before the study and 6 months, and between 3 months and 6 months, in the MRCDS, some indicators in the SGHRQ, and the TCMSS. There were no significant differences between the treatment group and control group in the remainder of the indices evaluated. In the treatment group, there were significant differences in before and after treatment in the MRCDS, SGHRQ, TCMSS and 6MWT. CONCLUSION: FGs were similar to JCs for IPF treatment.

Randomized controlled multicenter clinical trial for integrated treatment of community-acquired pneumonia based on traditional Chinese medicine syndrome differentiation.

OBJECTIVE: To evaluate the efficacy and safety of treatment based on syndrome differentiation of Traditional Chinese Medicine (TCM) for community-acquired pneumonia (CAP). METHODS: A total of 240 CAP patients were randomly divided into the following two groups: the control group was treated by anti-infection plus conventional medicine treatment; and the trial group was treated by TCM plus the above-mentioned treatment given to the controls. The course of treatment was 14 days, and the patients were followed up for 7 days. RESULTS: Of the 240 patients, 235 accomplished the whole process of treatment. The five patients who withdrew from the study were brought into an intent-to-treat analysis. The therapeutic effects of the trial group were superior to those of the control group (P < 0.01). The trial group took less time to become clinically stable, with a higher score in the quality of life (P < 0.01). There were no significant differences in mortality rate (P > 0.05), white blood cell count (P > 0.05), bacterial clearance rate (P > 0.05), and adverse reactions between the two integrated groups. CONCLUSION: Treatment based on TCM syndrome differentiation for CAP has the advantages of resulting in less time to achieve a stable clinical condition, improvement of clinical symptoms and quality of life, and is comparatively safe.
