Background: Complementary and alternative therapy is widely used to treat chronic obstructive pulmonary disease (COPD). A Chinese herbal medicine, JianPiYiFei (JPYF) II granules, have been shown to improve COPD patients' quality of life, however long-term effectiveness has not been examined. Purpose: To investigate whether long-term treatment with JPYF II granules is effective and safe for patients with stable, moderate to very severe COPD. Study design and methods: A multicentre, randomised, double-blinded, placebo-controlled trial was conducted. Eligible participants from six hospitals were randomly assigned 1:1 to receive either JPYF II granules or placebo for 52 weeks. The primary outcome was the change in St. George's Respiratory Questionnaire (SGRQ) score during treatment. Secondary outcomes included the frequency of acute exacerbations during treatment, COPD Assessment Test (CAT), 6-minute walking test (6MWT), lung function, body mass index, airflow obstruction, dyspnoea, exercise capacity (BODE) index, and peripheral capillary oxygen saturation (SpO2) at the end of treatment. Results: A total of 276 patients (138 in each group) were included in the analysis. JPYF II granules led to a significantly greater reduction in SGRQ score (-7.33 points, 95% CI -10.59 to -4.07; p < 0.0001) which reflects improved quality of life. JPYF II granules improved CAT (-3.49 points, 95% CI -5.12 to -1.86; p < 0.0001) and 6MWT (45.61 metres, 95% CI 20.26 to 70.95; p = 0.0005), compared with placebo. Acute exacerbations were less frequent with JPYF II granules than with placebo (0.87 vs. 1.34 events per patient; p = 0.0043). There were no significant differences between the groups in lung function, BODE index and SpO2. JPYF II granules were well tolerated and no significant adverse effects were noted. Conclusions: Long-term treatment with JPYF II granules is effective in moderate to very severe COPD, improving quality of life and exercise capacity, decreasing the risk of acute exacerbation, and relieving symptoms.

Background: Chinese herbal medicine (CHM) is thought to be a potential intervention in the treatment of coronavirus disease (COVID-19). Purpose: This study aimed to investigate the efficacy and safety of CHM or CHM combination therapy for COVID-19. Study design: Systematic review and meta-analysis Methods: We searched for relevant studies in the CNKI, CBM, Wanfang Data, PubMed, Cochrane Library, Embase, and other resources from their inception to April 15, 2020. Randomized controlled trials, cohort studies, and case-control studies on CHM or CHM combination therapy for COVID-19 were included. Meta-analysis was performed according to the Cochrane Handbook. Results: Overall, 19 studies with 1474 patients were included. Meta-analysis showed that the overall clinical effectiveness (OR = 2.67, 95% CI 1.83-3.89, I-2 = 0%), improvement in the CT scan (OR = 2.43, 95% CI 1.803.29, I-2 = 0%), percentage of cases turning to severe/critical (OR = 0.40, 95% CI 0.24-0.67, I-2 = 17.1%), reverse transcription-polymerase chain reaction (RT-PCR) negativity rate (OR = 2.55, 95% CI 1.06-6.17, I-2 = 56.4%) and disappearance rate of symptoms (fever, cough, and fatigue) were superior by combined CHM treatment of COVID-19. However, there was no statistical difference between the two groups in terms of length of hospital stay (WMD = -0.46, 95% CI -3.87 - 2.95, I-2 = 99.5%), and rate of adverse effects (OR = 1.21, 95% CI 0.48-3.07, I-2 = 43.5%). The quality of evidence was very low to low. Conclusion: The combined treatment of COVID-19 with Chinese and Western medicine may be effective in controlling symptoms and reducing the rate of disease progression due to low quality evidence.

Influenza is a major public health problem worldwide. Mutations and resistance development make the use of antiviral therapy challenging. Chinese patent medicines are often used to treat influenza in China and well tolerable. However, the misuse of Chinese patent medicines is common. We therefore aimed to develop an evidence-based guideline on treating influenza with Chinese patent medicines in adults to guide clinical practice. We formed a steering committee, a consensus panel, a consultants' group and an evidence synthesis team to guide the development of the guideline. We formulated the clinical questions through two rounds of survey, and finally selected five questions. We then systematically searched the related evidence and conducted meta -analyses, evidence summaries and GRADE decision tables to draft the recommendations, which the consensus panel then voted on using the Delphi method. Finally, we formulated six recommendations based on the evidence synthesis and experts' consensus. For treating mild influenza, we suggest either Lianhua Qingwen capsule, Jinhua Qinggan granule, Banlangen granule, Shufeng Jiedu capsule, or Jinfang Baidu pill, depending on the manifestations. For severe influenza, or mild influenza in patients at high risk of developing severe influenza, we suggest Lianhua Qingwen capsule in combination with antiviral medications and supportive therapy. The strength of all recommendations was weak. Traditional Chinese medicine has great potential to help in the fight against influenza worldwide, but more high-quality studies are still needed to strengthen the evidence.
