Background: Traditional Chinese medicine (TCM) has demonstrated considerable clinical efficacy in treating coronavirus disease 2019 (COVID-19). Puping Qinghua prescription (PPQH), a traditional Chinese medicine formulation, was found to be effective against clinical symptoms in patients with Omicron variant virus infection, Nonetheless, its safety and mechanism are unclear. Purpose: To provide evidence of validity and adverse events associated with PPQH in treating SARS-CoV-2 Omicron variants infection. Methods: Four hundred and eighty patients diagnosed with COVID-19 were randomised into the PPQH group (n = 240) and the LLQW group (n = 240). Basic information such as age, sex, vaccination status, symptoms, etc were registered. Laboratory tests for 142 patients, including cytokine levels and lymphocyte counts, liver and kidney function. Results: After intervention, levels of NK cells, IFN-alpha, IL-5, IL-6, and IL-12p70 were reduced in the PPQH group, whereas the levels of TNF-alpha, IL-1 beta, IL-4, IL-6, and IL-17A were reduced in the Lianhua Qingwen (LHQW) group (P < 0.05). PPQH was more effective in shortening duration of fever and reducing degree of cough compared with LHQW (P < 0.05). Liver and kidney functions remained unimpaired before and after intervention in both groups (P > 0.05). In addition, the incidence of adverse reactions such as palpitations, dizziness and sweating was lower in the PPQH group (P < 0.05). Conclusion: The efficacy of PPQH is comparable to LHQW in patients infected with Omicron variant virus. More excitingly, PPQH demonstrates a higher level of security.
OBJECTIVE:To investigate the antipyretic effect of early treatment with Traditional Chinese Medicine (TCM) on coronavirus disease 2019 (COVID-19) patients. METHODS:We retrospectively analyzed 369 patients from January 26th, 2020 to April 15th, 2020, who had been diagnosed with COVID-19. Among 92 eligible cases, 45 cases were identified as treatment group Ⅰ ( 45) and 47 cases were identified as treatment group Ⅱ. Patients in the treatment group Ⅰ were treated with TCM herbal decoction within 5 d after admission. Patients in the treatment group Ⅱ were treated with TCM herbal decoction after the 6th admission day. The onset time of antipyretic effect, the antipyretic time, the time of negative oropharyngeal swab nucleic acid conversion, and the changes of cell count in blood routine test were compared. RESULTS:The treatment group I showed shorter average antipyretic duration (4 7 d; <0.05), and shorter average time for polymerase chain reaction (PCR) nucleic acid test results to turn negative (7 11 d; <0.05) than the treatment group II. For patients ( 54) with body temperature>38 ℃, patients in the treatment group I had shorter median onset time of antipyretic effect than those in the treatment group II (3 4 d; <0.05). The absolute lymphocyte (LYMPH) count and absolute eosinophil (EOS) count on the 3rd day after admission and the neutrophil/lymphocyte ratio on the 6th day after admission of patients in the treatment group I were notably different from those in the treatment group II at the same time point (0.05). Based on Spearman's rank correlation analysis, the change of body temperature on the 3rd day after admission was positively correlated with the increase of EOS count and the increase of EOS count and LYMPH counts on the 6th day after admission (0.01). CONCLUSIONS:Early TCM intervention within 5 d after hospital admission shortened the onset time of antipyretic effect and fever duration of COVID-19 patients, reduced the time required for PCR test results to turn negative. Moreover, early TCM intervention also improved the results of inflammatory markers for COVID-19 patients. LYMPH and EOS counts can be used as indicators of TCM antipyretic effect.
Objectives:We previously revealed that scorpio and centipede (SC) improve the inflammatory response in asthma, whereas it is unclear whether ferroptosis is involved in this process.Materials and Methods:The asthmatic mouse model was established and lung tissues were collected for histopathological examination. The levels of tumor necrosis factor-α (TNF-α), interleukin- (IL-)1β, Fe2+, malondialdehyde (MDA), glutathione peroxidase 4 (GPX4), ferritin heavy chain 1(FTH1), and reactive oxygen species (ROS) were assessed in asthmatic mice and mouse airway epithelial cells.Results:Our results showed that ferroptosis was induced in asthmatic mice, as evidenced by the reduction of FTH1 and GPX4 expression and the increase of MDA and Fe2+ levels (all P<0.05). Ferrostatin-1 repressed inflammation and ferroptosis of asthmatic mice. Additionally, SC significantly inhibited the levels of TNF-α, IL-1β, MDA, and Fe2+, while enhancing FTH1 and GPX4 expression. However, SC plus erastin showed the reverse results. Moreover, ferroptosis remarkably increased in asthmatic airway epithelial cells, while SC suppressed ferroptosis of the cells (all P<0.05).Conclusion:SC ameliorated asthma by inhibiting the crosstalk between ferroptosis and inflammation in airway epithelial cells.
KeChuanLiuWei‐Mixture (KCLW) is widely used as a Chinese medicine prescription to treat severe asthma. However, the underlying therapeutic mechanism of KCLW remains unclear. In this study, a network pharmacology method was used to identify the chemical constituents of KCLW by the TCMSP database and ultra‐performance liquid chromatography coupled with time‐of‐flight mass spectrometry. Differential expression identification, protein–protein interaction (PPI) network and functional enrichment analysis were used to screen key targets of KCLW for severe asthma. Our results confirmed that quercetin, luteolin, kaempferol, and wogonin are the most critical active ingredients in KCLW. Moreover, the 16 relevant severe asthma‐related targets of KCLW were obtained by overlapping the PPI networks of the KCLW putative targets and severe asthma‐related genes, among which the most important targets were IL‐6, NOS2, VEGFA, CXCL2, and PLAT. Functionally, the 16‐targets and their interacting differentially expressed genes were primarily related to biological functions and pathways related to immunity and inflammation, such as inflammatory response, T cell differentiation, Nrf2/HO‐1 signaling pathway, TGF‐β/Smad signaling pathway, and NF‐κB signaling pathway. KCLW inhibited inflammation in PDGF‐BB‐induced airway smooth muscle cells. In summary, this study demonstrates the active substance and potential therapeutic mechanism of KCLW in severe asthma, and offers a clinical direction for KCLW against severe asthma.

Background: Coronavirus disease (COVID-19) seriously endangers global public health. Pupingqinghua prescription (PPQH) is an herbal formula from traditional Chinese medicine used for treatment of SARS-CoV-2 infection. This study aims to evaluate the clinical efficacy and safety of PPQH in Chinese participants infected with the SARS-CoV-2 Omicron variant. Methods: A total of 873 SARS-CoV-2 (Omicron)-infected patients were included. Among them, the patients were divided into the PPQH group (653 cases) and LHQW group (220 cases) according to different medications. The effectiveness indicators (hematological indicators, Ct values of novel Coronavirus nucleic acid tests, and viral load-shedding time) and safety indicators (liver and kidney function and adverse events) were analyzed. Results: There was no significant difference in baseline characteristics between the PPQH group and the LHQW group, except the gender; After the treatment, the levels of IL-5, IL-6, IL-10, NK cells, and INF-α of the patients in the PPQH group showed a downward trend (p < 0.05); The viral load shedding time was 5.0 (5.0, 7.0) in the PPQH group and 5.0 (4.0, 7.0) in the LHQW group; both PPQH and LHQW can shorten the duration of symptoms of fever, cough, and sore throat. The re-positive rate of COVID-19 test was 1.5 % in the PPQH group and 2.3 % in the LHQW group. In terms of safety, the levels of γ-GTT decreased significantly (p < 0.01); gastrointestinal reaction was the primary adverse reaction, and the reaction rate was 4.7 % in the PPQH group and 9.5 % in the LHQW group. Conclusion: PPQH can shorten the length of hospital stay and improve clinical symptoms of patients with SARS-COV-2 (Omicron), and it also has a good safety profile.
Asthma is one of the most common chronic inflammatory diseases. Although the scorpion and centipede (SC) significantly ameliorates asthma and changes exosomal miRNAs, the molecular mechanism is still obscure. Here, we show that SC improves inflammation in asthmatic mice and increases M2 macrophage-derived exosomes (M2Φ-Exos) by promoting M2 macrophage polarization. The M2Φ-Exos remarkably inhibits airway epithelial cell pyroptosis by reducing the expression of NLRP3, caspase-1, and LI-1β and mitochondrial swelling. Furthermore, miR-30b-5p is up-regulated in M2Φ-Exos compared with M1Φ-Exos. Overexpression of miR-30b-5p in M2Φ-Exos prevents airway epithelial cell pyroptosis, while down-regulation of miR-30b-5p promotes pyroptosis. We also uncover that pyroptosis is increased in asthmatic mice, while SC blocks pyroptosis. Moreover, miR-30b-5p overexpressed M2Φ-Exos further enhances the ameliorative effect of SC, which significantly down-regulates IRF7 expression. Our results collectively reveal that M2Φ-Exos induced by SC could carry miR-30b-5p to mitigate severe asthma by inhibiting airway epithelial cell pyroptosis. Most importantly, our findings may provide a potential clinical application of M2Φ-Exos for treating severe asthma.
Purpose . The purpose of this study is to study the effects of heat-clearing Traditional Chinese Medicine (TCM) in the stable stage of bronchiectasis via N-of-1 trials. Methods . The N-of-1 trials in this study were randomized and double-blinded with crossover comparisons consisting of three pairs. Each pair was of two 4-week periods. Each patient took the individualized decoction in the experimental period and the individualized decoction was removed of heat-clearing drugs, mainly including heat-clearing and detoxifying drugs, in the control period for three weeks. After three weeks, the patients stopped taking the decoction for one week. The primary outcome was from patients’ self-reporting symptoms scores on a 1–7-point Likert scale. Mixed-effects models were used to conduct statistical analysis on these N-of-1 trials. Results . Of the 21 patients enrolled, 15 completed three pairs of N-of-1 trials (71.43%). (1) Seen from the individual level, no statistical difference between the experimental decoction and the control ( P > 0.05) was observed. However, 5 patients found better decoctions according to the clinical criteria. (2) As revealed by the group data of all the N-of-1 trials, the control was better than the individualized decoction in terms of symptom scores on the Likert scale (1.94 ± 0.69 versus 2.08 ± 0.68, P = 0.04, mean difference, and 95% CI: 0.19 (0.01, 0.37)) and on CAT scores (13.66 ± 6.57 versus 13.95 ± 6.97, P = 0.04, mean difference, and 95% CI: 0.86 (0.042, 1.67)), but such differences were not clinically significant. The other outcomes, such as Likert scale score of respiratory symptoms and 24-hour sputum volume, showed no statistical difference. Conclusion . The experimental design of this study can make the TCM individualized treatment fully play its role and can detect the individualized tendencies according to the severity of phlegm and heat in some subjects. With the intermittent use or reduced use of heat-clearing drugs, most of the subjects, at the group level, enrolled in the series of N-of-1 trials may improve the symptoms and quality of life while saving the cost of TCM and reducing the potential side effects of heat-clearing TCM. This trial is registered with clinicaltrials.goc ( NCT03147443 ).

Background. Our previous studies showed that N-of-1 trials could reflect the individualized characteristics of traditional Chinese medicine (TCM) syndrome differentiation with good feasibility, but the sensitivity was low. Therefore, this study will use hierarchical Bayesian statistical method to improve the sensitivity and applicability of N-of-1 trials of TCM. Methods/Design. This is a randomized, double-blind, placebo-controlled, three-pair crossover trial for a single subject, including 4–8 weeks of run-in period and 24 weeks of formal trial. In this study, we will recruit a total of 30 participants who are in the stable stage of bronchiectasis. The trial will be divided into three pairs (cycles), and one cycle contains two observation periods. The medications will be taken for three weeks and stopped for one week in the last week of each observation period. The order of syndrome differentiation decoction and placebo will be randomly determined. Patient self-reported symptom score (on a 7-point Likert scale) is the primary outcome. Discussion. Some confounding variables (such as TCM syndrome type and potential carryover effect of TCM) will be introduced into hierarchical Bayesian statistical method to improve the sensitivity and applicability of N-of-1 trials of TCM, and the use of prior available information (e.g., “borrowing from strength” of previous trial results) within the analysis may improve the sensitivity of the results of a series of N-of-1 trials, from both the individual and population level to study the efficacy of TCM syndrome differentiation. It is the exploration of improving the objective evaluation method of the clinical efficacy of TCM and may provide reference value for clinical trials of TCM in other chronic diseases. This trial is registered with ClinicalTrials.gov (ID: NCT04601792).
