ABSTRACT

ObjectiveTo explore the guidance value of “treatment of disease in accordance with three conditions” theory in the prevention and treatment of corona virus disease 2019(COVID-19) based on the differences of syndromes and traditional Chinese medicine(TCM) treatments in COVID-19 patients from Xingtai Hospital of Chinese Medicine of Hebei province and Ruili Hospital of Chinese Medicine and Dai Medicine of Yunnan province and discuss its significance in the prevention and treatment of the unexpected acute infectious diseases. MethodDemographics data and clinical characteristics of COVID-19 patients from the two hospitals were collected retrospectively and analyzed by SPSS 18.0. The information on formulas was obtained from the hospital information system (HIS) of the two hospitals and analyzed by the big data intelligent processing and knowledge service system of Guangdong Hospital of Chinese Medicine for frequency statistics and association rules analysis. Heat map-hierarchical clustering analysis was used to explore the correlation between clinical characteristics and formulas. ResultA total of 175 patients with COVID-19 were included in this study. The 70 patients in Xingtai,dominated by young and middle-aged males,had clinical symptoms of fever, abnormal sweating,and fatigue. The main pathogenesis is stagnant cold-dampness in the exterior and impaired yin by depressed heat, with manifest cold, dampness, and deficiency syndromes. The therapeutic methods highlight relieving exterior syndrome and resolving dampness, accompanied by draining depressed heat. The core Chinese medicines used are Poria,Armeniacae Semen Amarum,Gypsum Fibrosum,Citri Reticulatae Pericarpium,and Pogostemonis Herba. By contrast,the 105 patients in Ruili, dominated by young females, had atypical clinical symptoms, and most of them were asymptomatic patients or mild cases. The main pathogenesis is dampness obstructing the lung and the stomach, with obvious dampness and heat syndromes. The therapeutic methods are mainly invigorating the spleen, resolving dampness, and dispersing Qi with light drugs. The core Chinese medicines used are Poria,Atractylodis Macrocephalae Rhizoma,Glycyrrhizae Radix et Rhizoma,Coicis Semen,Platycodonis Radix,Lonicerae Japonicae Flos, and Pogostemonis Herba. ConclusionThe differences in clinical characteristics, TCM syndromes, and medication of COVID-19 patients from the two places may result from different regions,population characteristics, and the time point of the COVID-19 outbreak. The “treatment of disease in accordance with three conditions” theory can help to understand the internal correlation and guide the treatments.

ABSTRACT

This study aims to investigate the etiology, pathogenic properties and pathogenic characteristics of corona virus disease-2019 (COVID-19) in traditional Chinese medicine(TCM), so as to provide ideas for clinical treatment based on syndrome differentiation. Efforts were made to retrive relevant literature concerning clinical studies, theoretical discussions and TCM diagnosis and treatment schemes issued by the state and various provinces, municipalities, autonomous regions and municipalities directly under the central government in relation to TCM from China Knowledge Network(CNKI) and Wanfang Database, and to analyze and summarize the etiology, pathology, theoretical viewpoints, clinical symptoms and signs, syndrome differentiation and medication rules. Currently, the common understanding of the etiology of COVID-19 in the field of TCM is the infection of "pestilential pathogen". However, there is a dispute over cold and heat or mixed understanding of cold and heat in terms of pathogenic attributes. The pathogenic factors are different from each other in dampness, toxin, dryness, fire (heat), wind, filth, depression, etc. There are various understandings on the pathogenesis including dampness, cold, heat, toxin, stasis, phlegm, stagnation, knot, dryness, filth, deficiency, blocking, collapse and asthma, etc. The etiology and pathogenesis are often mixed up. Integration of cold and heat, dryness and dampness, and other contradictory pathogens or pathogenesis is widely seen, which lacks the logicality of theoretical systems, and does not in line with the thinking characteristics of TCM on the etiology, pathogenesis, and syndrome differentiation of exogenous diseases. The main idea of medication in treatment is to diffuse the lung, clear away heat, eliminate dampness, resolve phlegm and repel foulness with aromatics. Maxing Shigantang is used as the core prescription. Chosen warm acrid drugs are mainly the ones with the effect of fragrance, removing dampness, resolving phlegm, and invigorating spleen. They are not the ones with the effects of warming yang and dissipating cold, but the combination of cold and heat, suggesting the complexity of etiology and pathogenesis. COVID-19 is categorized as plaque in TCM, and its etiology is "pestilential pathogen". This pestilential pathogen possesses not only the basic properties of toxin and filth, but also the characteristics of dampness, heat and wind. Throughout the course of the disease, phlegm, stasis, stagnation and other secondary pathogenic factors also occur. The evolution of pathogenesis is characterized by depression, blocking, and deficiency. There are more evidences that the pestilential pathogen of COVID-19 belongs to heat property no matter in the aspects of clinical manifestation, transmission law (syndrome differentiation at different stages), or in compatibility of medication.

ABSTRACT

Qing-Fei-Pai-Du decoction (QFPDD) is a Chinese medicine compound formula recommended for combating corona virus disease 2019 (COVID-19) by National Health Commission of the People's Republic of China. The latest clinical study showed that early treatment with QFPDD was associated with favorable outcomes for patient recovery, viral shedding, hospital stay, and course of the disease. However, the effective constituents of QFPDD remain unclear. In this study, an UHPLC-Q-Orbitrap HRMS based method was developed to identify the chemical constituents in QFPDD and the absorbed prototypes as well as the metabolites in mice serum and tissues following oral administration of QFPDD. A total of 405 chemicals, including 40 kinds of alkaloids, 162 kinds of flavonoids, 44 kinds of organic acids, 71 kinds of triterpene saponins and 88 kinds of other compounds in the water extract of QFPDD were tentatively identified via comparison with the retention times and MS/MS spectra of the standards or refereed by literature. With the help of the standards and in vitro metabolites, 195 chemical components (including 104 prototypes and 91 metabolites) were identified in mice serum after oral administration of QFPDD. In addition, 165, 177, 112, 120, 44, 53 constituents were identified in the lung, liver, heart, kidney, brain, and spleen of QFPDD-treated mice, respectively. These findings provided key information and guidance for further investigation on the pharmacologically active substances and clinical applications of QFPDD.

ABSTRACT

Objective: To discuss the diagnosis, treatment, and multidisciplinary management of a child with hepatoblastoma (HB) and suspected coronavirus disease (COVID-19). Methods: A child with HB and suspected COVID-19 was admitted to the Children's Hospital, Zhejiang University School of Medicine, in February 2020. The diagnosis and treatment plan were discussed by a multidisciplinary team (MDT). After the MDT discussion, necessary examinations and tests were performed, including routine blood tests, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) ribonucleic acid (RNA) and antibody tests, tumor marker tests, chest and abdomen computed tomography (CT), and an ultrasound. The administered treatment included the cisplatin+5-fluorouracil+vincristine (C5V) regimen and cefotaxime. Results: The patient was diagnosed as low-risk HB and completed the first stage of HB chemotherapy after the diagnosis of COVID-19 was ruled out. After 1 week in the hospital, the patient's body temperature returned to normal, the disposition and appetite improved, and all indexes reached the discharge standard. After 14 days of isolation, the patient was discharged. Conclusions: For children with newly diagnosed HB suspected of having COVID-19 during the pandemic period, clinicians must consider the prevention and control of COVID-19 while diagnosing and treating HB as soon as possible. Multidisciplinary management is beneficial for ensuring the development of a safe and efficient treatment plan.

ABSTRACT

The worldwide outbreak of a novel coronavirus (COVID-19) in December 2019 significantly affected the routine diagnosis and treatment of breast cancer due to resource and staffing constraints. In addition, breast cancer patients have poor immunity and are, therefore, more susceptible to COVID-19. If they are infected, the risk of severe illness is extremely high. Therefore, finding a balance between the effective prevention and control of COVID-19 and diagnosing and treating patients with breast cancer is a significant clinical issue during the pandemic. Therefore, the National Cancer Quality Control Center Breast Cancer Expert Committee brought together experts to urgently compile a "Guideline for the Rationalized Diagnosis and Treatment of Breast Cancer during the Outbreak of Corona Virus Disease 2019". Here, we will interpret the core recommendations in the guideline for breast cancer diagnosis and treatment.

ABSTRACT

Since its emergence in December 2019, corona virus disease 2019 (COVID-19) has impacted several countries, affecting more than 90 thousand patients and making it a global public threat. The routes of transmission are direct contact, and droplet and possible aerosol transmissions. Due to the unique nature of dentistry, most dental procedures generate significant amounts of droplets and aerosols, posing potential risks of infection transmission. Understanding the significance of aerosol transmission and its implications in dentistry can facilitate the identification and correction of negligence in daily dental practice. In addition to the standard precautions, some special precautions that should be implemented during an outbreak have been raised in this review.

ABSTRACT

The situation of Corona Virus Disease 2019 (COVID-19) is still severe at present. In order to better fight against the epidemic and give full play to the advantages of traditional Chinese medicine, we explored the feasibility of acupuncture therapy in the intervention of COVID-19 through analyzing the relevant literature in both ancient and modern time. Additionally, we analyzed the intervention scheme of acupuncture for COVID-19 developed by China Association of Acupuncture and Moxibustion and supplemented the protocol of the intervention with auricular acupuncture. It was proposed that the advantages of acupuncture and moxibustion should be fully displayed while Chinese herbal medications have been applied in the treatment of COVID-19. During treatment, acupuncture physicians should be rationally allocated to a certain proportion so as to adequately utilize comprehensive therapeutic approaches and guarantee people's safety to the greatest extent. Eventually, the clinical therapeutic effect may be improved, the national resources be economized on and the COVID-19 epidemic be conquered early.

ABSTRACT

Through literature review and group discussion, Special Expert Group for Control of the Epidemic of Novel Coronavirus Pneumonia of the Chinese Preventive Medicine Association formulated an update on the epidemiological characteristics of novel coronavirus pneumonia (NCP). The initial source of the 2019 novel coronavirus (2019-nCoV) was the Huanan seafood market in Wuhan, Hubei province, China, with pangolins as a potential animal host. Currently the main source of infection is NCP patients, and asymptomatic carriers may also be infectious. The virus is believed transmitted mostly via droplets or contact. People are all generally susceptible to the virus. The average incubation period was 5.2 days, and the basic reproductive number R0 was 2.2 at the onset of the outbreak. Most NCP patients were clinically mild cases. The case fatality rate was 2.38%, and elderly men with underlying diseases were at a higher risk of death. Strategies for prevention and control of NCP include improving epidemic surveillance, quarantining the source of infection, speeding up the diagnosis of suspected cases, optimizing the management of close contacts, tightening prevention and control of cluster outbreaks and hospital infection, preventing possible rebound of the epidemic after people return to work from the Chinese Spring Festival holiday, and strengthening community prevention and control.

ABSTRACT

In this paper, based on the supramolecular "Qi chromatography" of traditional Chinese medicine (TCM), combined with the characteristics of corona virus disease 2019 (COVID-19), the historical origin and characteristics of theoretical research on the treatment of epidemic diseases by TCM were analyzed retrospectively, and the key scientific problems for achieving its modernization were proposed, and the countermeasures were illustrated. In fact, the emergence and development history of TCM epidemic theory is a comprehensive and scientific understanding of biomolecular chemistry for epidemic caused by pathogen. From the exploration of the cause of abnormal Qi to the epidemic pathogenic factor, from the treatment based on syndrome differentiation by six meridians to by the defensive Qi and nutrient blood and the triple energizer, which is gradually close to the modern theoretical system of infectious diseases and immunology, all of which are stamped with brand of TCM supramolecular "Qi chromatography" theory. In the long history of biological evolution in nature, the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) as epidemic pathogenic factor in TCM, human body and Chinese materia medica are biological supramolecules at a specific stage of evolution in nature, which are controlled by the "imprinting templates" of molecular society in gradual biomolecules, with the unchanged laws of mutual advancement, mutation, suitability and mutual restriction. Based on the analysis of the law of supramolecular action hiding in the prevention and treatment of epidemic diseases dealt with TCM on procession of principle-method-recipe-medicines, this paper discusses the key scientific problems of its modernization and puts forward the solutions. It can not only clarify the scientific principle of the prevention and treatment with TCM, develop the multi-component Chinese medicine, accelerate the control of the epidemic situation, but also promote the solution of original frontier key scientific problems such as the material basis of meridians, viscera and syndromes, and the compatibility law of the TCM prescription, in order to protect the existing medical resources and open up a new situation in the modernization of TCM research.

ABSTRACT

The outbreak of corona virus disease-2019 (COVID-19) not only endangers the public life and health, but also poses threats to the public mental health. Under the atmosphere of tension and fear, the public often produces adverse emotional reactions to psychological stress, and even has extreme behaviors, which seriously affects physical and mental health. Traditional Chinese medicine (TCM) emotional therapy is based on the TCM consciousness theory in adherence to the holistic view of "integration of mind and body". It adopts safe and effective emotional conditioning methods to regulate mood, eliminate bad emotions, maintain mental health, and enhance the body's immunity to achieve the effect of treating or preventing physical and mental diseases. It has differentiated applications in many medical fields, such as post-traumatic stress disorder, generalized anxiety disorder, cancer and hospice, with good clinical efficacy. By analyzing the theoretical origin, research status, application range of TCM sentiment therapy, as well as the current public psychological state of the COVID-19 epidemic, we innovatively proposed TCM sentiment therapies, such as calm emotion method, diversion of attention method, suggestive induction method, obedient mind method, music delight method, TCM refreshing method and auricular pressing method, and comprehensively applied them in the public psychological adjustment during the outbreak, with the aim to provide rational and effective psychological guidance, help the public to correctly understand various bad emotions during the outbreak, enhance their abilities to cope with it and adjust psychological problems, maintain a good mentality, and pass the epidemic period smoothly. At the same time, in order to make better use of the advantages of TCM sentiment therapy and benefit the public, it is advocated to widely apply TCM sentiment therapy in similar public health events and public psychological care in the daily life, for the purpose of preventing before disease outset and preventing progress of disease, and effectively protecting the physical and mental health of the people.

ABSTRACT

The outbreak of corona virus disease-2019 (COVID-19) in Wuhan, China, in December 2019, is highly contagious and epidemic, and belongs to the category of "plague" in traditional Chinese medicine, which seriously threatens human life and health. In the face of this sudden public health event, based on the theory of Wenyilun, this paper analyzes the onset characteristics, transmission, and syndrome differentiation-based treatment of COVID-19 in clinical practice. According to the characteristics of this epidemic, the pathogeny of COVID-19 is "epidemic pathogenic factors", and the pathogenesis is that the epidemic suppresses the dampness. Its transmission follows the regularity of "nine transmissions between exterior and interior" recorded in Wenyilun, which can be divided into sequential transmission and reverse transmission. The course of the disease has certain regularity and stages. In the early stage, the pathogen hides in the pleurodiaphragmatic interspace, and the epidemic suppresses the dampness, the treatment shall reach the pleurodiaphragmatic interspace, clear the dampness and turbidness, diffuse the lungs and dredging the lung meridian. In the middle stage, the pathogen can be transmitted to the exterior, the treatment shall be pungent in flavor and cool in property and could relieve the exterior syndrome, so as to remove the pathogen by shivering and sweating. If the dampness toxin enters the interior and be transmitted into the heat, and caused damage to the lung meridian, obstruction of Qi in the lungs, interior excess and heat accumulation, the treatment shall dredge bowel and purge heat, and expel the pathogen out. Any delay in treatment, mistreatment or excessive pathogen can lead to pathogenic invasion into the pericardium, and cause delirium, dysphoria, reversal cold of limbs, barely palpable pulse and other critical manifestations of internal blocking causing external depletion. The treatment shall focus on both attack and supplement, open blocking and relieve depletion. In the recovery period, due to the residual pathogen and the Yin and Qi impairment caused by fever, the treatment shall prevent the recurrence of the residual pathogen, nourish Yin and blood, and restore the vital energy. During the treatment, WU You-ke put forward three principles of "removing the pathogen as the priority, and then avoiding false sweating, and caring for the spleen and stomach". The theory of Wenyilun has a systematic understanding of the pathogeny, pathogenesis, and syndrome differentiation-based treatment of "the epidemic", and provides valuable experience for fight against plagues in later generations, which is also of great significance for the prevention and treatment of COVID-19.

ABSTRACT

Since the outbreak of corona virus disease-2019 (COVID-19), the timely intervention of Chinese medicine has played an important role, it can significantly improve the clinical symptoms of patients, alleviate fever, cough, shorten the course of disease and reduce the conversion rate of mild disease to severe disease, moreover, it has obvious advantages in improving survival rate, prognosis and quality of life in patients. In order to make better use of the therapeutic effect of Chinese medicine and overcome the epidemic situation as soon as possible, various provinces, municipalities and autonomous regions have introduced local Chinese medicine treatment schemes in accordance with the geography, climate and epidemic situation. In this article, we have analyzed the similarities and differences among treatment schemes from the perspective of three factors, and it is believed that the onset season is the same for this disease, and the differences between treatment schemes mainly depend on geographical and climatic factors. The results showed that in seven regions of China, the early symptoms in warm and humid regions such as Central China, South China, East China and Southwest China were characterized by "wet, warm, hot, and toxic", and treatment schemes mainly adopted the recipes with clearing heat and detoxifying, strengthening spleen and removing dampness functions. The early symptoms in cold regions such as Northeast China, North China, and Northwest China were mostly characterized by "cold, wet, wind, and toxic", and the therapeutic recipes emphasized on the effects of expelling wind and cold, removing toxicity and dampness. Among them, the national plan with the Hubei epidemic situation as an important reference has gradually evolved from a single syndrome attribute of each period to both cold and hot syndromes with multiple treatment methods. With the development of the disease, epidemic toxin and toxic heat in the lungs are the main characteristics in the medium term, when the treatment mainly focuses on purging heat and removing toxins. In severe cases and advanced stage, internal block and outward desertion are the main symptoms, when the treatment mainly focuses on block dredging and relieving desertion. In the recovery period, deficiency of lung and spleen Qi, and deficiency of Qi and Yin are the main symptoms, when the treatment is mainly used to invigorate the spleen, tonify the lungs, and nourish Qi and Yin. The physical factors are mostly reflected in the prevention program, so they are rarely mentioned in the treatment program. The Chinese medicine treatment schemes of COVID-19 in different regions show obvious differences. It is of great significance to analyze these differences and sum up the corresponding laws for the differential prevention and treatment of infectious diseases like COVID-19.

ABSTRACT

Corona virus disease 2019 (COVID-19), which broke out in Wuhan, HuBei in December, 2019, spread around the country in a short term. Some infected patients suffered from severe acute respiratory syndrome. It has become a major public health event of international concern. COVID-19 patients are the main source of transmission and most people get infection easily, so the current main prevention method is interrupting the pathway of transmission. The dental treatments are very special because these operations produce substantial aerosols and lead a high risk of cross-infection, which brings challenge for epidemic prevention and control. In this paper, the characteristics of aerosols and prevention methods of aerosol transmission in dental clinics are mainly discussed.

ABSTRACT

More than 220 million Chinese children and adolescents are confined to their homes because of the corona virus disease 2019 (COVID-19) outbreak. Thanks to the strong administrative system in China, the emergency home schooling plan has been rigorously implemented. Although these measures and efforts are highly commendable and necessary, there are reasons to be concerned because prolonged school closure and home confinement during a disease outbreak might have negative effects on children's physical and mental health. It is the responsibility and keen interests of all stakeholders, from governments to parents, to ensure that the physical and mental impacts of the COVID-19 epidemic on children and adolescents are kept minimal.
