Clinical Efficacy of Chinese Medicine Combined with Indirect Moxibustion Plaster on COVID-19 Patients During Recovery Period Based on COVID-19 Diagnosis and Treatment Protocol（Tenth Edition） / 中国实验方剂学杂志

ObjectiveTo observe the clinical efficacy of Chinese medicine combined with indirect moxibustion plaster on corona virus disease 2019 （COVID-19） patients during recovery period. MethodNinety patients of COVID-19 during the recovery period were randomly divided into a Chinese medicine group， an indirect moxibustion plaster group， and a combination group，with 30 cases in each group. According to the 10th edition of COVID-19 Diagnosis and Treatment Protocol，patients in the Chinese medicine group received oral Chinese medicine based on syndrome differentiation，one dose per day， twice a day. Patients in the indirect moxibustion plaster group were treated with indirect moxibustion plaster at Zusanli （ST 36）， Pishu （BL 20）， Dazhui （GV 14）， Feishu （BL 13）， Kongzui （LU 6）， and Tiantu （CV 22），once a day，40 min each time. Patients in the combination group were treated with Chinese medicine combined with indirect moxibustion plaster. Treatment lasted two weeks. Before and after treatment，the traditional Chinese medicine （TCM） symptom score，pulmonary computed tomography （CT） score，St. George's Respiratory Questionnaire （SGRQ） score，blood routine indexes ［white blood cell count （WBC），neutrophil count （NEUT），and lymphocyte count （LYM）］， and inflammatory indexes ［C-reactive protein （CRP），serum ferritin， and interleukin-6 （IL-6）］ were observed in the three groups. The clinical efficacy was evaluated. ResultAfter treatment，the scores of TCM symptoms，pulmonary CT， and SGRQ，CRP，IL-6，and ferritin in the three groups decreased（P<0.05），while WBC and LYM increased（P<0.05）， but there was no significant difference in NEUT. The above indexes in the combination group were better than those in the other two groups（P<0.05）. After treatment， the cured and markedly effective rate was 76.7% （23/30） in the combination group， 50.0% （15/30） in the Chinese medicine group， and 46.7% （14/30） in the indirect moxibustion plaster group. The cured and markedly effective rate of the combination group was significantly higher than that of the Chinese medicine group （χ2=4.593， P<0.05） and the indirect moxibustion plaster group （χ2=5.711， P<0.05）. The total effective rate was 96.7 % （29/30） in the combination group， 93.3% （28/30） in the Chinese medicine group， and 86.7% （26/30） in the indirect moxibustion plaster group. The total effective rate of the combination group was higher than that of the Chinese medicine group and the indirect moxibustion plaster group， but the differences were not statistically significant. ConclusionChinese medicine combined with indirect moxibustion plaster can effectively improve the clinical symptoms，promote pulmonary inflammation，blood routine indexes， and inflammatory indexes， and improve the quality of life of COVID-19 patients during the recovery period，which is more advantageous than Chinese medicine alone or indirect moxibustion plaster.

Research progress of angiotensin converting enzyme 2 co-expression in non-small cell lung cancer and SARS-CoV-2 / 中国胸心血管外科临床杂志

@#Since the first case of corona virus disease 2019 (COVID-19) caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) at the end of 2019, the virus has spread rapidly around the world and has become a global public health problem. In the process of this virus epidemic, compared with the general population, cancer patients are considered to be highly susceptible people, especially the lung cancer patients. Some studies have shown that angiotensin converting enzyme 2 (ACE2) may be the pathway for SARS-CoV-2 to infect the host. At the same time, ACE2 is often abnormally expressed in non-small cell lung cancer. Therefore, understanding the respective mechanisms of ACE2 in COVID-19 and non-small cell lung cancer has extremely important reference value for the study of vaccines and therapeutic drugs, and also provides meaningful guidance for the protection of patients with lung cancer during the epidemic. This article reviews the possible invasive mechanism of ACE2 in SARS-CoV-2 and its abnormal expression in non-small cell lung cancer.

Effects of delayed ureteral stents removal during the COVID-19 pandemic on the quality of life and psychological status of postoperative patients with urinary calculi / 北京大学学报(医学版)

OBJECTIVE@#To explore the impacts of delayed ureteral stent removal on the quality of life (QoL) and mental health of urinary calculi postoperative patients due to the corona virus disease 2019(COVID-19) pandemic.@*METHODS@#The demographic and clinical data of patients with ureteral stent placement after urinary endoscopic lithotripsy and returned to Peking University People's Hospital for stent removal from December 2019 to June 2020 were collected. Ureteral stent symptoms questionnaire (USSQ) score and the outcome 20-item self-rating anxiety scale (SAS) and self-rating depression scale (SDS) were collected to estimate the QoL and mental status. The USSQ consisted of 44 questions in 6 domains (including urinary symptom, physical pain, general health, work performance, sexual function, and ureteral stent related infection). For most questions in each domain, its score was a five-point Likert-type scale from 1 to 5, and a small proportion of questions was quantified by 1 to 4 or 1 to 7 scale. SAS and SDS both contained 20 questions used to assess a patient's level of anxiety and depression. Its scoring for each item was on a four-point Likert-type scale from 1 to 4. A total score (ranging from 20 to 80) was the main statistical indicator. The level of clinical anxiety and depression was quantified by using standard scores (total score multiplied by 1.25 to produce integers). And the multi-group structural equation model was constructed by analysis of moment structure (AMOS) analysis.@*RESULTS@#Overall, 71 patients were enrolled for analysis. It was found that the median duration of ureteral stent time differed significantly between the control and delayed groups for 32 (30, 33) d and 94.5 (88, 103) d, respectively. The delayed group resulted in higher scores in the USSQ multidimensional, which included urinary symptoms, general health, work performance and ureteral stent related infections. Anxiety and depression were also significantly serious in the delayed group than in the control group. A longer indwelling time of a ureteral stent could exacerbate the effects of urinary symptoms and physical pain on work performance (P=0.029 < 0.05). Among them, the patients with severe urinary symptoms leading to poor work performance were most significantly affected by prolonged ureteral stent duration time (CR=2.619>1.96).@*CONCLUSION@#Patients with delayed ureteral stent removal due to the COVID-19 had resulted in worse QoL and mental status. Stents related symptoms are more severe in patients with higher anxiety and depression degree during COVID-19. To improve the QoL and mental health of patients after urinary calculi surgery during COVID-19, it is still not recommended to prolong the stent duration time or corresponding intervention measures should be taken.

Characteristics of Traditional Chinese Medicine Syndromes and Treatments of COVID-19 Patients from Two Hospitals Based on “Treatment of Disease in Accordance with Three Conditions” / 中国实验方剂学杂志

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.

Clinical Evidence and Theory of COVID-19 by Traditional Chinese Medicine / 中国实验方剂学杂志

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.

Comprehensive profiling and characterization of the absorbed components and metabolites in mice serum and tissues following oral administration of Qing-Fei-Pai-Du decoction by UHPLC-Q-Exactive-Orbitrap HRMS / 中国天然药物

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.

Multidisciplinary diagnosis and treatment of a child with hepatoblastoma and suspected coronavirus disease / 中国肿瘤临床

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.

Interpretation of guidelines for the diagnosis and treatment of breast cancer during the COVID-19 outbreak / 中国肿瘤临床

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.

Epidemiological investigation on the first family aggregation epidemic of corona virus disease 2019 in Yangzhou / 上海预防医学

Objective To explore the transmission pattern of corona virus disease 2019 (COVID-19) in the population by describing an imported case of novel coronavirus infected pneumonia epidemic situation. Methods Using the method of field investigation, epidemiological investigations were carried out for the imported COVID-19 case and the close contacts related to this epidemic cluster.Data were collected concerning the date of onset, isolation of the case and close contacts.The novel coronavirus nucleic acid was collected from the throat swabs of the case and close contacts.These samples were detected by real-time fluorescence quantitative RT-PCR. Results In this epidemic cluster, there was one confirmed case, that had been exposed to 36 people (12 in the family and 24 outside the family) and 2 in the family were nucleic acid positive and diagnosed as asymptomatic infections. Conclusion COVID-19 transmission proves to be mainly through respiratory droplets and close contact, which easily causes family aggregation epidemic.

An update on the epidemiological characteristics of novel coronavirus pneumonia（COVID-19） / 中华流行病学杂志

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.

Possible aerosol transmission of COVID-19 and special precautions in dentistry / 浙江大学学报（英文版）（B辑：生物医学和生物技术）

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.

Feasibility analysis on acupuncture therapy for the treatment of Corona Virus Disease 2019 and the exploration on the application scheme / 针刺研究

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.

Aerosol transmission prevention of novel coronavirus in dental clinics / 上海交通大学学报（医学版）

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.

Mitigate the effects of home confinement on children during the COVID-19 outbreak / 上海交通大学学报（医学版）

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.
