[Progress of researches on anti-inflammatory mechanism of acupuncture underlying amelioration of chronic respiratory diseases].

In recent years, acupuncture has gained great progress in the treatment of chronic respiratory diseases (CRD), and the clinical effect is remarkable, but its underlying mechanisms are relatively complex, with the anti-inflammatory effect being the primary aspect. Based on the literature both at home and abroad, we found that the anti-inflammatory mechanism of acupuncture mainly involves chemokines, kinase-related pathways, helper T cells, epigenetic modification, autophagy, vagal-mediated cholinergic anti-inflammatory pathway, etc. The researches on some anti-inflammatory mechanisms are still in the initial stage, the relationship among various pathways, and the key factors affecting the effect of acupuncture, such as acupoint selection, stimulation intensity and needling depth, etc. warrant further exploration in the future.

Acupuncture for dyspnea and breathing physiology in chronic respiratory diseases: A protocol of a systematic review and meta-analysis of randomized controlled trials.

BACKGROUND: Dyspnea is one of the most common symptoms of chronic respiratory disease (CRD) and is closely related to increased functional disability and mortality, resulting in substantial adverse outcomes on patients and imposing great social and economic burden. Although multiple clinical trials and systematic reviews have suggested that acupuncture could be effective in treating COPD and lung cancer, little is known about its effects on dyspnea relief in patients with CRD. The present study aimed to use a systematic review approach to evaluate the effectiveness and safety of acupuncture in the treatment of dyspnea in patients with CRD. METHODS: We will search the following 9 databases from inception to June 30, 2022, PubMed, Web of Science, EMBASE, Cochrane Central Register of Controlled Trials, Chinese National Knowledge Infrastructure, WANFANG Database, Chinses Scientific and Technological Periodical Database, and Chinese Biomedical Database, and the Cochrane Library Database. Clinical randomized controlled trials in English or Chinese that evaluate invasive acupuncture versus control group in treatment of CRD with dyspnea will be included. The primary outcome will be dyspnea scores, breathing physiological function, and the secondary outcomes include exercise tolerance by six-minute walk distance quality of life, quality of life and adverse events. Two reviewers will independently conduct study selection, data extraction and quality assessment. The Review Manager software will be used for meta-analysis. This protocol will be carried out in accordance with the PRISMA-P guidance. CONCLUSION: This systematic review and meta-analysis will provide the evidence of whether acupuncture is an effective and safe intervention for CRD with dyspnea. The results will be disseminated through peer-reviewed publication.

[Research progress of neuroendocrine mechanism of acupuncture for dyspnea].

The paper reviewed the relevant studies on dyspnea treated with acupuncture over the past 20 years, as well as the underlying neuroendocrine mechanism from the perspective of central and peripheral vagus nerves, neurotransmitter, respiratory muscle function and anti-depression-anxiety function. It revealed that the central response area was regulated by acupuncture in treatment of dyspnea, which is similar to the area affected in acupuncture analgesia. Additionally, acupuncture generates its therapeutic effects on dyspnea through promoting the release of endogenous opioid peptides and the regulation of autonomic nerve, amygdale and hypothalamic-pituitary-adrenal axis.

Physiological and metabolic analysis of winter jujube after postharvest treatment with calcium chloride and a composite film.

BACKGROUND: Ziziphus jujuba Miller cv. Dongzao is extremely susceptible to reddening, browning, nutritional loss, and perishability after harvest. In this study, we evaluated the mechanisms of calcium chloride and chitosan/nano-silica composite film treatments on the quality, especially in reddening, by physiological and metabolomic assays. RESULTS: The treatment delayed the decline of phenylalanine ammonia-lyase (PAL), chalcone synthase (CHS), and chalcone isomerase (CHI) activities. Meanwhile, the treated groups retarded the increases in anthocyanin and quercetin contents by inhibiting the gene expressions of flavonol synthase (ZjFLS), dihydroflavonol 4-reductase (ZjDFR), and anthocyanidin synthase (ZjANS), while promoting leucoanthocyanidin reductase (ZjLAR) expression, which leads to retardation of fruit reddening. Anthocyanins were found to be responsible for post-harvest winter jujube reddening through principal component analysis. Results from the technique for order preference by similarity to an ideal solution indicated that the treated group delayed the decline of the quality of 'Dongzao' and extended its shelf life. CONCLUSION: The treatment induced the heightening of flavonoids metabolism. They enhanced the nutritional value and the ability to resist stress by delaying the decline of PAL, CHS, and CHI activities. Meanwhile, the treated groups retarded the increase in anthocyanin and quercetin contents by inhibiting the gene expressions of ZjFLS, ZjDFR, and ZjANS and promoting ZjLAR expression, which leads to retardation of fruit reddening. Anthocyanins are responsible for post-harvest winter jujube reddening. Coating treatment effectively delayed the decline of winter jujube quality. © 2020 Society of Chemical Industry.

The effect of acupoint application of traditional Chinese medicine for the treatment of chronic obstructive pulmonary disease: A protocol for systematic review and meta-analysis.

BACKGROUND: Chronic obstructive pulmonary disease (COPD) is a public threat, leading to progressive physical activity and poor quality of life. Although modern medicine has excellent achievement of COPD, the recurrence rate of stable COPD and the mortality of acute exacerbation COPD remain high. As one of the external therapy of traditional Chinese medicine, acupoint application has been treated COPD in China for a long time. Nevertheless, study evaluating the effect of acupoint application for COPD could not satisfy needs for clinic. METHOD: Randomized controlled trials meeting the inclusion criteria will be collected by the 2 reviewers. We choose the following electronic databases of Web of Science, Pub Med, EMBASE, Cochrane Library, China National Knowledge Infrastructure, Wan Fang, Chinese Scientific Journals Database, and Chinese Biomedical Database as our retrieval tool. The retrieval time was from inception to March 2020. The key to evaluation criteria is total clinical efficacy rate and lung function will be measured. Secondary outcomes include assessment scales and adverse reactions. The studies extracted will be assessed. The merging analysis will be carried out by Review Manager Software. RESULT: A scientific evidence of efficacy and safety of acupoint application for COPD will be found. CONCLUSION: The evaluation of the efficacy and safety of acupoint application for COPD will be presented. INPLASY REGISTRATION NUMBER: INPLASY202090023.

Clinical efficacy and safety of Ganshuang granules as an adjuvant treatment for chronic hepatitis B liver fibrosis: A protocol for systematic review and meta analysis.

BACKGROUND: Chronic hepatitis B liver fibrosis is significant public concern. Ganshuang granules (GSG) are used to treat liver fibrosis for a long time.

Comparative Proteomic Profiling and Biomarker Identification of Traditional Chinese Medicine-Based HIV/AIDS Syndromes.

Given the challenges in exploring lifelong therapy with little side effect for human immunodeficiency virus infection and acquired immune deficiency syndrome (HIV/AIDS) cases, there is increasing interest in developing traditional Chinese medicine (TCM) treatments based on specific TCM syndrome. However, there are few objective and biological evidences for classification and diagnosis of HIV/AIDS TCM syndromes to date. In this study, iTRAQ-2DLC-MS/MS coupled with bioinformatics were firstly employed for comparative proteomic profiling of top popular TCM syndromes of HIV/AIDS: accumulation of heat-toxicity (AHT) and Yang deficiency of spleen and kidney (YDSK). It was found that for the two TCM syndromes, the identified differential expressed proteins (DEPs) as well as their biological function distributions and participation in signaling pathways were significantly different, providing biological evidence for the classification of HIV/AIDS TCM syndromes. Furthermore, the TCM syndrome-specific DEPs were confirmed as biomarkers based on western blot analyses, including FN1, GPX3, KRT10 for AHT and RBP4, ApoE, KNG1 for YDSK. These biomarkers also biologically linked with the specific TCM syndrome closely. Thus the clinical and biological basis for differentiation and diagnosis of HIV/AIDs TCM syndromes were provided for the first time, providing more opportunities for stable exertion and better application of TCM efficacy and superiority in HIV/AIDS treatment.
