ObjectiveTo investigate the potential mechanism of action of the Qufeng Tongqiao Cough-relieving Decoction (祛风通窍止咳方, QTCD) in the treatment of upper airway cough syndrome (UACS). MethodsTwenty-four guinea pigs were randomly divided into blank group, model group, traditional Chinese medicine (TCM) group, and inhibitor group, with six guinea pigs in each group. Except for the blank group, guinea pigs were sensitized with ovalbumin and aluminum hydroxide via intraperitoneal injection, followed by ovalbumin nasal drops combined with smoke exposure to establish the UACS model. After modeling, the TCM group was administered QTCD 0.9 g/(100 g·d) by gavage, the inhibitor group received the transient receptor potential vanilloid receptor 4 (TRPV4) inhibitor GSK2193874 1 mmol/L, 5 min by nebulisation, and the blank group and model group were given 2 ml/(100 g·d) normal saline by gavage once daily. After 7 days of treatment, a cough provocation test was performed using 0.4 mol/L citric acid. The levels of IgE in serum and inflammatory cytokines, including interleukin-6 (IL-6), interleukin-8 (IL-8) in serum, bronchoalveolar lavage fluid (BALF), and nasal lavage fluid (NLF) were detected by enzyme-linked immunosorbent assay (ELISA). Histopathological changes in lung and nasal mucosal tissues were observed by hematoxylin-eosin (HE) staining. Immunohistochemistry was used to detect the protein levels of TRPV4, substance P (SP), and calcitonin gene-related peptide (CGRP) in lung and nasal mucosal tissues. Real-time polymerase chain reaction (Real-time PCR) was used to detect the mRNA expression of TRPV4, SP, and CGRP in lung tissues. ResultsHE staining showed significant structural damage and infiltration of inflammatory cells in the lung and nasal mucosal tissues in the model group, while the TCM group and inhibitor group showed improved pathological changes. Compared with the blank group, the model group showed increased cough frequency, serum IgE level, and IL-6 and IL-8 levels in serum, BALF, and NLF. The protein levels of TRPV4, SP, and CGRP in lung and nasal mucosal tissues and their mRNA expression were elevated (P<0.05 or P<0.01). Compared with the model group, the TCM group and inhibitor group showed reduced cough frequency, serum IgE level, and TRPV4 and SP mRNA expression in lung tissues. The TCM group showed reduced IL-6 and IL-8 levels in serum, BALF, and NLF, and reduced TRPV4 and CGRP protein levels in lung and nasal mucosal tissues. The inhibitor group showed reduced IL-6 and IL-8 levels in serum, BALF, and NLF, reduced IL-6 in BALF, reduced IL-8 in NLF, and decreased TRPV4, SP, and CGRP protein levels in lung tissues and SP and CGRP protein levels in nasal mucosal tissues (P<0.05 or P<0.01). Compared with the TCM group, the inhibitor group had increased serum IgE, IL-6, and IL-8 levels, increased IL-6 level in BALF, and increased IL-8 levle in NLF, but decreased SP protein level in lung tissues and increased TRPV4 and SP mRNA expression in lung tissues (P<0.01). ConclusionQTCD effectively reduces cough frequency in the UACS guinea pig model. Its mechanism may involve inhibiting the activation of the TRPV4 pathway, improving airway neurogenic inflammation, alleviating inflammatory responses, and reducing cough hypersensitivity.

OBJECTIVE To establish high performance liquid chromatography (HPLC) fingerprint of Xiaohe syrup and determine the contents of 10 effective ingredients in them. METHODS With 12 batches of Xiaohe syrup as samples, ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS) was adopted with Athena C18 (250 mm×4.6 mm, 5 μm) as the chromatographic column, acetonitrile-0.1% phosphoric acid aqueous solution as mobile phase for gradient elution. The flow rate was 1.0 mL/min, and the detection wavelength was 210 nm. Similarity Evaluation System for Traditional Chinese Medicine Chromatographic Fingerprint (2012A version) was imported to establish the fingerprint of Xiaohe syrup and evaluate the similarity. The content determination was performed on ACQUITY UPLC BEH C18( 100 mm×2.1 mm, 1.7 μm) chromatographic column, with 0.01% formic acid acetonitrile-0.01% formic acid water as mobile phase for gradient elution at a flow rate of 0.4 mL/min; combined with high-resolution mass spectrometer, positive and negative ions were scanned with an electric spray ion source to determine the content of each main component in 12 batches of Xiaohe syrup. RESULTS A total of 33 common peaks were calibrated in 12 batches of samples, with similarities greater than 0.97; 10 chromatographic peaks were confirmed, namely flavonoid glycosides, paeoniflorin, ferulic acid, naringin, rosmarinic acid, neohesperidin, salvianolic acid B, tetrahydropalmatine, saikosaponin A, and saikosaponin D. The results of content determination showed that the above 10 components had good linear relationships within their respective mass concentration ranges (all R 2>0.999), with contents ranging from 0.35 to 0.64, 3.15 to 5.61, 0.11 to 0.17, 1.68 to 3.17, 1.59 to 1.90, 1.15 to 1.64, 0.78 to 1.48, 0.11 to 0.26, 0.06 to 0.13, and 0.33 to 0.61 mg/mL, respectively. CONCLUSIONS The main components of 12 batches of Xiaohe syrup are similar, but the contents vary; HPLC fingerprint and UPLC-MS/MS content determination method established in this study can be used for comprehensive quality evaluation of Xiaohe syrup.

Neutrophils as the first immune responders to infection can quickly identify and eliminate pathogens. The mainly rely on glycolysis to exert their killing functions. Although researches on the metabolic shifs that affect neutrophil functions began early, little is known about how neutrophils undergo metabolic transformation during the anti-infection process. It has been proven that glycogen metabolism plays an important role in regulating the functions of neutrophils. Other metabolic pathways besides glycolysis, such as mitochondrial metabolism and fatty acid oxidation during neutrophil differentiation, have potential contributions to the regulation of neutrophils′ functions. This review summaries current studies about metabolic regulatory effects of neutrophils on anti-infection responses, intending to provide reference for further study on the metabolism of neutrophils.
