Research progress in Fangfeng Tongsheng Powder / 国际中医中药杂志

Fangfeng Tongsheng Powder has the effect of dispersing wind heat and internal purging heat. Returning to the origin of Liu Wansu's academic thought, it can be concluded that Fangfeng Tongsheng Powder should be based on the treatment of wind as the symptoms, the treatment of heat as the root, the treatment of both the symptoms and the root, and the double solution of the exterior and the interior. It should be set up for the syndrome of excessive heat and internal and external excess. In recent years, the basic and clinical research directions of this prescription in China mainly include skin diseases, endocrine and metabolic diseases, digestive system diseases, respiratory diseases, etc., while foreign related research focuses on obesity-related metabolic diseases. Studies have found that Fangfeng Tongsheng Powder has the effects of anti-allergy, regulating immunity and improving metabolic disorders. At present, the basic research on Fangfeng Tongsheng Powder in China is relatively insufficient, and the mechanism of Fangfeng Tongsheng Powder needs to be further explored, and more large samples and high-quality RCTs need to be carried out.

Research progress in gout-induced bone destruction mechanism / 中国组织工程研究

BACKGROUND:In chronic gout patients,sodium urate is deposited in bone joints and around synovial membranes,eroding and destroying bone,leading to serious complications such as gouty arthritis and deformity.Research on the mechanisms by which sodium urate crystals erode and destroy bone can help early clinical intervention in gouty diseases and prevent and delay the complications caused by bone destruction. OBJECTIVE:To explore the destructive effects of gout crystals on bone through clinical imaging studies and experimental basic research,review the current progress and development prospects of research on the phenomenon and mechanism of bone destruction caused by gout,guide the clinical early intervention of gouty bone destruction,and guide the direction of research on the role of bone destruction. METHODS:The Chinese search terms were"gout,bone destruction,bone erosion"and the English search terms were"tophi,gout,RANKL,bone destruction,bone erosion,"which were used in the computer search of WanFang and PubMed databases.Finally,64 articles were selected for review according to the inclusion and exclusion criteria. RESULTS AND CONCLUSION:The specific manifestations of clinical studies(imaging,histopathology)to some extent elaborate the osteolytic process of gout,and in basic studies,the mechanism of gout-causing bone destruction can be divided into the five aspects:(1)Sodium acid crystals have an important role in bone destruction,directly affecting osteocytes,chondrocytes,osteoblasts and proresorptive factors that promote bone destruction;(2)Receptor activator of nuclear factor-κB ligand and other proresorptive factors are involved in bone destruction;(3)T cell-mediated cellular immunity functions as a bridge in bone destruction,and activated T cells induce osteoclast differentiation;(4)Monocytes/macrophages are not only precursors of osteoclast-like cells,but also induce the expression of proresorptive factors such as Receptor activator of nuclear factor-κB ligand;(5)Neutrophils affect the morphology of osteoclast arrangement,and neutrophil extracellular trap networks promote osteolysis by promoting osteoclast differentiation.

Intervention of Chinese Herbal Medicine Formulas on Oxidative Stress of Chronic Obstructive Pulmonary Disease： A Review / 中国实验方剂学杂志

Chronic obstructive pulmonary disease （COPD） is a common disease in clinical practice. It is associated with obvious exposure to toxic particles or gases and has become the leading cause of death and disability worldwide. The pathogenesis of COPD is complex， and the oxidative stress involved in COPD plays a crucial role in the pathological process of the disease. Patients with COPD usually have high levels of oxidative stress in the lungs， which will affect the whole body for a long time， causing a variety of complications and accelerating the development of the disease. On the one hand， oxidative stress can directly damage the airway and lung tissue. On the other hand， it also drives other pathological mechanisms to jointly promote the development of disease， such as participating in inflammatory reactions and protease/anti-protease imbalance， promoting mucus secretion， accelerating cellular senescence， causing autoimmunity， and involving in genetic regulatory pathways. At present， western medicine treatment is mostly based on conventional drug treatment， and antioxidant-targeted oxidative stress is adopted， but there are still some challenges in efficacy and safety. Traditional Chinese medicine has a long history of preventing and treating COPD. In particular， Chinese herbal medicine formulas have great potential to interfere with the oxidative stress of COPD. Whether it is the modified classical traditional Chinese medicine or the new formulation developed by modern doctors， the research results reflect the multi-target and multi-channel advantages of traditional Chinese medicine treatment， and their efficacy and safety are gradually verified. This paper reviewed the literature in recent years， starting with the basic and clinical research on the intervention of traditional Chinese herbal medicine formulas on oxidative stress of COPD， so as to provide further ideas for related research on the prevention and treatment of oxidative stress of COPD by traditional Chinese medicine.

Expression and function of α7 nicotinic acetylcholine receptor in thymocytes of myasthenia gravis patients / 中国胸心血管外科临床杂志

@#Objective    To investigate the expression of α7 nicotinic acetylcholine receptor (α7 nAChR) in thymocytes of patients with myasthenia gravis (MG) and its effect on cytokine secretion and T cell proliferation. Methods    Patients with MG who underwent expanded thoracoscopic thymectomy in the Comprehensive Diagnosis and Treatment Center of the Henan Provincial People’s Hospital from June 2021 to June 2022 were selected and allocated to a MG group. Patients who underwent partial thymectomy to expose the surgical field during the cardiac disease surgery from June 2021 to September 2022 in the Department of Adult Cardiac Surgery of Fuwai Huazhong Cardiovascular Hospital were selected as the control group. Thymic single cell suspensions were prepared from MG and control groups, and the expression of α7 nAChR in thymocytes of the two groups was detected by real-time polymerase chain reaction and Western blotting. Then CD3/CD28 monoclonal antibody coupled with magnetic beads was used to induce T cell activation, and the levels of cytokines interferon-gamma (IFN-γ), tumor necrosis factor-α (TNF-α), interleukin-4 (IL-4), IL-6, IL-10, IL-17, and IL-21 in thymocytes of the two groups were detected by enzyme-linked immunosorbent assay (ELISA). The activated T cells of the MG group were divided into a blank control group, an α7 nAChR antagonist group, and an α7 nAChR agonist group according to different treatment methods. After 72 hours of culture, IFN-γ, TNF-α, IL-4, IL-6, IL-10, IL-17, and IL-21 expression levels in the culture supernatant were measured by ELISA. Afterwards, CD4-PE and CD8-APC antibodies were added, and the proliferation of T cell subsets was detected by flow cytometry. Results    A total of 10 MG patients were collected, including 3 males and 7 females with an average age of 19.25±6.28 years; and 15 control patients were collected, including 6 males and 9 females with an average age of 26.18±6.77 years. Compared with the control group, the mRNA and protein levels of α7 nAChR in the thymocytes of MG group were decreased, and the expression levels of IFN-γ, TNF-α, IL-4, IL-6 and IL-21 in the supernatant were increased (P<0.05), but there was no statistical difference in the expression of IL-10 and IL-17 (P>0.05). The cell-culture experiment showed that compared with the blank control group, the levels of IFN-γ, TNF-α, IL-6 and IL-21 secreted by T cells in the α7 nAChR antagonist group were increased (P<0.05), while they were decreased in the α7 nAChR agonist group (P<0.05). There was no statistical difference in the secretion levels of IL-4, IL-10 or IL-17 among the three groups (P>0.05). CD4+ T and CD8+ T cells in the α7 nAChR agonist group were significantly less than those in the blank control group and α7 nAChR antagonist group (P<0.001), while they were significantly more in the α7 nAChR antagonist group than those in the blank control group (P<0.001). Conclusion    The expression of α7 nAChR in thymocytes of MG patients is decreased, and α7 nAChR may be involved in the inflammatory response in thymocytes and thus in thymic function.

Evaluation of Animal Models of Acute Lung Injury Caused by Non-physical Factors Based on Data Mining / 中国实验方剂学杂志

ObjectiveTo study the characteristics of animal models of acute lung injury caused by non-physical factors， so as to provide a reference for the standardization of the preparation of such animal models and lay a foundation for the research on the pathogenesis and the diagnosis and treatment of acute lung injury. MethodThe articles about the animal experiments of acute lung injury published in the last decade were retrieved from China National Knowledge Infrastructure （CNKI）， Wanfang， SinoMed， VIP， and PubMed with the theme terms of "acute lung injury" and "animal model". The animal species， drugs used in modeling， modeling period， methods used in molding， model standards， and model evaluation indicators were summarized， and Excel was used for the frequency analysis. ResultA total of 338 articles were included in this study. The results of the frequency analysis showed that SD rats/C57BL/6 mice were mainly used to establish the animal models of acute lung injury. Male mice were mostly used for modeling， and the commonly used modeling agent was lipopolysaccharides （LPS）. In most cases， the modeling lasted for 6 h after drug administration. Hematoxylin-eosin staining was mainly used for the observation of histological changes in the lungs， which were taken as the criteria for modeling. The established models were mainly evaluated based on lung dry/wet weight ratio， lung index， morphological changes in the lung tissue， myeloperoxidase （MPO）， superoxide dismutase （SOD）， and levels of inflammatory cytokines in the serum and bronchoalveolar lavage fluid （BALF）. ConclusionThe models of acute lung injury were mostly prepared by intraperitoneal injection of LPS （5 mg·kg-1） in SD rats and tracheal instillation of LPS （5 mg·kg-1） in C57BL/6 mice， which were praised for the simple operation， high success rate， and consistent with the pathogenesis of acute lung injury. This study provides a reference for the basic research on acute lung injury by animal experiments.

Basic research of meridian-tendon based on fascia: review and prospects / 中国针灸

Meridian-tendon is a central concept in meridian theory of TCM, and its basic research has been increasingly emphasized. While there is no unified understanding of the essence of meridian-tendon, the concept that function of fascia could partially reflect the functions of meridian-tendons has reached consensus in the academic community. This article suggests that under the guidance of meridian-tendon theory, based on previous research foundation of fascia, focusing on adopting fascia research methods, the mechanisms of tender point hyperalgesia and abnormal proliferation related to meridian lesions should be adopted to explain yitong weishu (taking the worst painful sites of muscle spasm as the points), and the mechanisms of meridian intervention efficacy should be adopted to explain yizhi weishu (feelings from patients and acupuncture operators). Furthermore, this article provides an analysis of the future trends in basic research of meridian tendons.

Report on Cardiovascular Health and Diseases in China 2021: An Updated Summary / 生物医学与环境科学（英文）

In 2019, cardiovascular disease (CVD) accounted for 46.74% and 44.26% of all deaths in rural and urban areas, respectively. Two out of every five deaths were due to CVD. It is estimated that about 330 million patients suffer from CVD in China. The number of patients suffering from stroke, coronary heart disease, heart failure, pulmonary heart disease, atrial fibrillation, rheumatic heart disease, congenital heart disease, lower extremity artery disease and hypertension are 13.00 million, 11.39 million, 8.90 million, 5.00 million, 4.87 million, 2.50 million, 2.00 million, 45.30 million, and 245.00 million, respectively. Given that China is challenged by the dual pressures of population aging and steady rise in the prevalence of metabolic risk factors, the burden caused by CVD will continue to increase, which has set new requirements for CVD prevention and treatment and the allocation of medical resources in China. It is important to reduce the prevalence through primary prevention, increase the allocation of medical resources for CVD emergency and critical care, and provide rehabilitation services and secondary prevention to reduce the risk of recurrence, re-hospitalization and disability in CVD survivors. The number of people suffering from hypertension, dyslipidemia and diabetes in China has reached hundreds of millions. Since blood pressure, blood lipids, and blood glucose levels rise mostly insidiously, vascular disease or even serious events such as myocardial infarction and stroke often already occured at the time of detection in this population. Hence, more strategies and tasks should be taken to prevent risk factors such as hypertension, dyslipidemia, diabetes, obesity, and smoking, and more efforts should be made in the assessment of cardiovascular health status and the prevention, treatment, and research of early pathological changes.

Major Chinese Ethnic Medicines for Prevention and Treatment of Ischemic Heart Diseases： A Review / 中国实验方剂学杂志

In China， the incidence of ischemic heart disease （IHD） is increasing year by year， which brings enormous burden to families and society. It is urgent to find preferable treatment methods and medical therapies. The Chinese ethnic minority medicine has gradually developed unique theoretical systems and therapeutic characteristics on the basis of clinical experience and thinking modes including image-number thinking and the holistic perspective. Consequently， it possesses huge application capacity and research value in prevention and treatment of IHD. Belonging to the medical system based on the view of nature and life， the Tibetan medicine， Mongolian medicine， and Dai medicine have respectively formed theories like "three elements" "three life-sustaining energies" "four elements and five skandhas （aggregates）" ， have put forward unique understandings of IHD and have formed corresponding therapeutic principles and methods， generating plentiful classic prescriptions represented by Sanwei Tanxiang powder， Bawei Chenxiang powder， Roukou Wuwei pills and Yajiao Hadun powder. They also contain characteristic ethnic medicine resources such as Choerospondiatis Fructus， Rhodiola Rosea and Draconis Sanguis. Aiming to provide enlightenment and reference for the clinical application and development of the Chinese ethnic minority medicine for the prevention and treatment of IHD， the authors try to summarize the related researches represented by Tibetan and Mongolian medicines， and then discuss the opportunities and challenges faced by such researches.
