Practice and experience in the teaching system of clinical pharmacy laboratory in the post-epidemic era: A review.

Out of the global outbreak of COVID-19, clinical pharmaceutical therapeutic analytical-teaching laboratories underwent an increasing number of digitally-led teaching research. A teaching system working online and offline to monitor medicinal drugs was explored and established using a clinical pharmaceutical therapy through a drug concentration monitoring laboratory within a comprehensive tertiary hospital. Meanwhile, laboratory access training and standards of laboratory biosafety management system were also strictly implemented, improving the technical operation and daily management. Moreover, a new, significant, and efficient teaching mode was set up based on vocational training needs for efficient and professional learning. The learning results are enforced to have dynamic checks accomplished using stage-oriented assessment. Moreover, the questionnaire survey results, especially during independent learning ability and laboratory skills training, reveal that teachers and students have commented positively on the new teaching mode. Hereon, a clinical pharmaceutical teaching system during the Post-Epidemic Era was elaborated to provide a unique teaching mode and experience dedicated to teaching and scientific research in clinical therapeutic drug monitoring laboratory.

Prospect of compassionate use in China from remdesivir. / ä»Žç‘žå¾·è¥¿éŸ¦å±•æœ›ä¸­å›½åŒæƒ ç”¨è¯.

Compassionate use may play an important role in responding to major public health emergencies. The Jinyintan Hospital in Wuhan launched the III phase of clinical trials of antiviral drug-remdesivir on February 6, 2020. As an unapproved drug, remdesivir raised great concerns about compassionate use in China. Compassionate use is therapeutic use of unauthorized drugs outside of clinical trials. It is used for critically ill patients with life-threatening diseases and no effective treatment means in China. Patients voluntarily apply to their medical institutions. The Center for Drug Evaluation, National Medical Products Administration shall conduct scientific and reasonable review, approval, and supervision on patients' application for compassionate medication. By analyzing and comparing the current situation of compassionate use at home and abroad, it is expected to provide thinking for the development of compassionate use system in China.

Role of Hypertension on the Severity of COVID-19: A Review.

ABSTRACT: The novel coronavirus disease (COVID-19) caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has rapidly evolved into a global pandemic. The substantial morbidity and mortality associated with the infection has prompted us to understand potential risk factors that can predict patient outcomes. Hypertension has been identified as the most prevalent cardiovascular comorbidity in patients infected with COVID-19 that demonstrably increases the risk of hospitalization and death. Initial studies implied that renin-angiotensin-aldosterone system inhibitors might increase the risk of viral infection and aggravate disease severity, thereby causing panic given the high global prevalence of hypertension. Nonetheless, subsequent evidence supported the administration of antihypertensive drugs and noted that they do not increase the severity of COVID-19 infection in patients with hypertension, rather may have a beneficial effect. To date, the precise mechanism by which hypertension predisposes to unfavorable outcomes in patients infected with COVID-19 remains unknown. In this mini review, we elaborate on the pathology of SARS-CoV-2 infection coexisting with hypertension and summarize potential mechanisms, focusing on the dual roles of angiotensin-converting enzyme 2 and the disorders of renin-angiotensin-aldosterone system in COVID-19 and hypertension. The effects of proinflammatory factors released because of immune response and gastrointestinal dysfunction in COVID-19 are also discussed.

COVID-19 in gastroenterology and hepatology: Lessons learned and questions to be answered.

BACKGROUND: Although coronavirus disease 2019 (COVID-19) presents primarily as a lower respiratory tract infection, increasing data suggests multiorgan, including the gastrointestinal (GI) tract and liver, involvement in patients who are infected by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). AIM: To provide a comprehensive overview of COVID-19 in gastroenterology and hepatology. METHODS: Relevant studies on COVID-19 related to the study aim were undertaken through a literature search to synthesize the extracted data. RESULTS: We found that digestive symptoms and liver injury are not uncommon in patients with COVID-19 and varies in different individuals. The most common GI symptoms reported are diarrhea, nausea, vomiting, and abdominal discomfort. Other atypical GI symptoms, such as loss of smell and taste and GI bleeding, have also been reported along with the evolvement of COVID-19. Liver chemistry abnormalities mainly include elevation of aspartate transferase, alanine transferase, and total bilirubin. It is postulated to be related to the binding of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) virus to the angiotensin converting enzyme-2 receptor located on several different human cells. CONCLUSION: Standardized criteria should be established for diagnosis and grading of the severity of GI symptoms in COVID-19 patients. Gastroenterology and hepatology in special populations, such as children and elderly, should be the focus of further research. Future long-term data regarding GI symptoms should not be overlooked.

The potential application of probiotics and prebiotics for the prevention and treatment of COVID-19.

COVID-19 is a pandemic disease caused by the novel coronavirus severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). This new viral infection was first identified in China in December 2019, and it has subsequently spread globally. The lack of a vaccine or curative treatment for COVID-19 necessitates a focus on other strategies to prevent and treat the infection. Probiotics consist of single or mixed cultures of live microorganisms that can beneficially affect the host by maintaining the intestinal or lung microbiota that play a major role in human health. At present, good scientific evidence exists to support the ability of probiotics to boost human immunity, thereby preventing colonization by pathogens and reducing the incidence and severity of infections. Herein, we present clinical studies of the use of probiotic supplementation to prevent or treat respiratory tract infections. These data lead to promising benefits of probiotics in reducing the risk of COVID-19. Further studies should be conducted to assess the ability of probiotics to combat COVID-19.

A critical review: traditional uses, phytochemistry, pharmacology and toxicology of Stephania tetrandra S. Moore (Fen Fang Ji).

ABSTRACT: Stephania tetrandra S. Moore (S. tetrandra) is distributed widely in tropical and subtropical regions of Asia and Africa. The root of this plant is known in Chinese as "Fen Fang Ji". It is commonly used in traditional Chinese medicine to treat arthralgia caused by rheumatism, wet beriberi, dysuria, eczema and inflamed sores. Although promising reports have been published on the various chemical constituents and activities of S. tetrandra, no review comprehensively summarizes its traditional uses, phytochemistry, pharmacology and toxicology. Therefore, the review aims to provide a critical and comprehensive evaluation of the traditional use, phytochemistry, pharmacological properties, pharmacokinetics and toxicology of S. tetrandra in China, and meaningful guidelines for future investigations.

Providing pharmacy services during the coronavirus pandemic.

The coronavirus disease 19 (COVID-19) is quickly spreading across China and globally. Pharmacy services are an important pillar in public health to prevent and contain the COVID-19 pandemic. Chinese pharmacists have acted swiftly in the public health response in China, such as drafting professional service guidance to pharmacists and pharmacies, establishing emergency drug formularies, monitoring and resolving drug shortages, establishing remote pharmacy services to prevent human-to-human infections, providing event-driven pharmaceutical care, educating the public on infection prevention and disease management, and participating in clinical trials and drug evaluation. This commentary reviews the unique needs of pharmacy services in the COVID-19 pandemic, and shares our experiences with the international pharmacy community in the response to these needs.
