Systematic pharmacology and experimental validation to elucidate the inflammation-associated mechanism of Huanglian Wendan (HLWD) decoction in the treatment of MAFLD associated with atherosclerosis.

ETHNOPHARMACOLOGICAL RELEVANCE: Metabolic-associated fatty liver disease (MAFLD) and atherosclerosis are very common disorders that frequently coexist. The therapeutic efficacy of Huanglian Wendan (HLWD) decoction, a traditional Chinese medicine (TCM) prescription, is satisfactory in treating MAFLD associated with atherosclerosis. However, the underlying mechanisms through which HLWD exerts its effects need to be elucidated. Given the complex composition of HLWD and its multiple therapeutic targets, pharmacological investigation is challenging. AIM OF THIS STUDY: This study aimed to identify the effective compounds in HLWD and elucidate the mechanisms involved in its therapeutic effect on MAFLD associated with atherosclerosis. MATERIALS AND METHODS: We used a systematic pharmacology method to identify effective compounds present in HLWD and determine the mechanism by which it affects MAFLD associated with atherosclerosis. The effective components of HLWD were identified through ultrahigh-performance liquid chromatography-q exactive-orbitrap high resolution mass spectrometry (UHPLC-Q-Orbitrap HRMS). Next, a comprehensive in silico method was used to predict potential related targets and disease targets for these compounds to establish corresponding pathways. The accuracy of our assumed systemic pharmacology results was determined by conducting follow-up experiments. RESULTS: By conducting UHPLC-Q-Orbitrap HRMS combined with network analysis, we identified 18 potentially active components of HLWD and assessed the inflammatory regulatory mechanism by which it affects MAFLD associated with atherosclerosis on the basis of 52 key targets. We used a high-fat, high-cholesterol (HFHC)-induced mice model of MAFLD associated with atherosclerosis to confirm our results. We found that administering HLWD significantly improved the appearance of their liver and reduced their body weight, liver weight, blood lipids, hepatic damage, and hepatic pathology. HLWD also decreased atherosclerotic lesion areas, foam cells, and inflammatory cells in the aorta. HLWD showed anti-inflammatory effects, suppressed M1 polarization, and promoted M2 polarization in the liver and aorta. HLWD might also regulate peroxisome proliferator-activated receptor-γ (PPARγ)/nuclear factor kappa-B (NF-κB) signaling to influence macrophage polarization and inflammation. CONCLUSIONS: Our results showed that HLWD protected against HFHC diet-induced MAFLD associated with atherosclerosis by regulating PPARγ/NF-κB signaling, thus adjusting macrophage polarization and inflammation. Additionally, pharmacochemistry research, network pharmacology analysis, and experimental verification can be combined to form a comprehensive model used in studies on TCM.

Sepsis is a major disease that threatens human life and health. Clinically, it is mainly based on supportive treatment and lacks specific treatment methods. Acupuncture has important clinical significance in the prevention and treatment of sepsis. In the present paper, we systematically searched CNKI and PubMed databases, included the clinical trials and animal experiments on the prevention and treatment of sepsis with acupuncture, summarized the clinical efficacy and the mechanism of acupuncture. Results indicate that the role of acupuncture therapies in improving sepsis involves inhibiting systemic inflammatory response, alleviating oxidative stress, regulating immune system, and resisting cell apoptosis, thus having a protective effect on multiple organs. The mechanism involves multiple signaling pathways and related factors.

[Acupoit is the "transducer" in the physiochemical information coupling response of acupuncture].

Acupoint is the initial response site of acupuncture stimulus and also the source link of the effect onset of acupuncture. Acupuncture is a mechanical physical stimulus. How is the mechanical force of acupuncture transduced into neuroelectrical and biochemical signals at acupoint? How does the physiochemical information of acupoint launch acupuncture effect? All of these remain the common and crucial questions in the study of acupuncture effect mechanism. Physical changes are induced in the local tissue of acupoint by needling techniques, such as the deformation and displacement of muscle fibers, which may act on the nerve ending receptors and produce electroneurographic signals. Besides, these changes may activate the mechanosensitive ion channels of the cytomembrane in acupoint site. Through cellular signal transduction, the physical signals may be transformed into chemical ones to trigger the physiochemical coupling response of acupoint microenvironment. Eventually, acupuncture effect is generated via nerves and body fluids. "The mechanical force of acupuncture", through "the physiochemical transduction", promotes the body's perception and transmits acupuncture signals. It suggests that acupoint is the "transducer" in the physiochemical information coupling response of acupuncture.

["Acupuncture network drug"--transformation and application strategies of exosomes based on characteristics of network regulation of acupuncture therapy].

Although the basic mechanism of acupuncture-moxibustion has been revealed from many aspects, there are still many shackles in the transformation of the related research achievements. The transformation of academic achievements of experimental acupunctology is an urgent issue to be solved at present. Network regulation is the basic action mode of acupuncture therapy. In the present paper, we proposed that the "acupuncture network drug" could carry a variety of effective active ingredients which may be the core component of network regulation of acupuncture therapy. The "exosomes", polyvesicle derived from the intracellular lysosomal microparticles invagination, contain complex RNAs and proteins and exist in the body fluids and function in secreting abundant activate substances to participate in intercellular communication, which is the research hotspot in the field of frontier life science in the world. They play an important role in the diagnosis and treatment of diseases, and drug development, etc.. Our studies using rats with adjuvant arthritis and mice with sepsis displayed that after intraperitoneal administration of serum exosomes derived from normal animals receiving acupuncture intervention, an acupuncture-like analgesic effect and an anti-inflammatory effect were achieved, respectively. It is thus possible that acupuncture network drugs could be developed from serum exosomes secreted by exosome autogenous living cells after acupuncture intervention by virtue of the characteristics of low immunogenicity and may have great advantages in drug development and modification. It is also expected to provide new ideas for the transformation of experimental research results and to in depth give explanations about the underlying mechanisms of acupuncture therapy.

The effectiveness of cupping therapy on chronic fatigue syndrome: A single-blind randomized controlled trial.

BACKGROUND: and purpose: We investigated the effectiveness of cupping therapy with three different pressures in patients with chronic fatigue syndrome (CFS). MATERIALS AND METHODS: The participants were randomly assigned to three groups, as follows: cupping pressure of -0.02 mpa (n = 38), -0.03 mpa (n = 38), or -0.05 mpa (n = 36). Each group received cupping treatment that consisted of 10 sessions over 5 weeks (2 sessions per week). The primary outcomes were Fatigue Scale (FS-14) score and Fatigue Assessment Instrument (FAI) score after 5 and 10 sessions. The secondary outcomes were the Self-Rating Anxiety Scale (SAS) score, the Self-Rating Depression Scale (SDS) score, and the Pittsburgh Sleep Quality Index (PSQI) score. RESULTS: There were 91 participants who completed the trial. After five sessions of treatment, the primary outcome of FS-14 score decreased by 3.20 (2.19, 4.21) in the -0.02 mpa group, by 2.39 (1.51, 3.27) in the -0.03 mpa group, and by 3.40 (2.28, 4.52) in the -0.05 mpa group (P = 0.667). After 10 sessions of treatment, the outcome of FS-14 score decreased by 5.00 (3.79, 6.21) in the -0.02 mpa group, by 4.06 (3.07, 5.05) in the -0.03 mpa group, and by 4.77 (3.52, 5.94) in the -0.05 mpa group (P = 0.929). And, the results were statistically different between 5 sessions and 10 sessions of treatment (P < 0.01). However, there were no statistical differences in FAI, SAS, SDS, and PSQI scores between the three groups after 5 sessions and 10 sessions of treatment. CONCLUSIONS: In conclusion, cupping therapy has significantly relieved fatigue symptoms and improved emotion and sleep condition of CFS patients, and 10 sessions of treatment had superior results compared with 5 sessions in each group. Moreover, in 5 sessions of treatment, cupping with high pressure showed better improvement in fatigue syndromes and sleep condition according to effective rates. TRIAL REGISTRATION: Chinese clinical trial registry (ChiCTR1800017590); Ethical approval number: ChiECRCT-20180085.

A New Perspective of Acupuncture: The Interaction among Three Networks Leads to Neutralization.

Acupuncture has been used to treat multiple medical conditions, but whether the diverse effects of acupuncture are intrinsically linked and how they might be connected have yet to be determined. More and more researches have shown that acupuncture is a kind of nociceptive stimulus, which can cause inflammatory reaction in the sites of acupuncture and then further activate the nerve-endocrine-immune systems to cause the cascade amplification of the acupuncture effect. This review seeks to provide a comprehensive summary of the existing literature concerning the role of "acupoint-meridian-disease network" in various effects of acupuncture and suggest a novel notion that acupuncture may restore homeostasis under different pathological conditions by regulating this network, resulting in the activation of different reaction cascades in response to pathological injury. We think that acupuncture acts on acupoints, first activating the small network of acupoints (Acupoint Network). The information of acupuncture is amplified by cascade, and the nerve endocrine immune system (NEI) is activated through the large network of meridians (Meridian Network) of the body itself. The nerve-endocrine-immune system (NEI) further outputs the effect information to the target organ through multilevel and multisystems and finally acts on the disease network (Disease Network) to produce acupuncture effect.
