Wang, J, Zhao, X, Feng, W, Li, Y, Peng, C
The American journal of Chinese medicine. 2021;(8):1965-1999
Abstract
Pulmonary fibrosis (PF) is a chronic and irreversible interstitial lung disease that even threatens the lives of some patients infected with COVID-19. PF is a multicellular pathological process, including the initial injuries of epithelial cells, recruitment of inflammatory cells, epithelial-mesenchymal transition, activation and differentiation of fibroblasts, etc. TGF-[Formula: see text]1 acts as a key effect factor that participates in these cellular processes of PF. Recently, much attention was paid to inhibiting TGF-[Formula: see text]1 mediated cell processes in the treatment of PF with Chinese herbal medicines (CHM), an important part of traditional Chinese medicine. Here, this review first summarized the effects of TGF-[Formula: see text]1 in different cellular processes of PF. Then, this review summarized the recent research on CHM (compounds, multi-components, single medicines and prescriptions) to directly and/or indirectly inhibit TGF-[Formula: see text]1 signaling (TLRs, PPARs, micrRNA, etc.) in PF. Most of the research focused on CHM natural compounds, including but not limited to alkaloids, flavonoids, phenols and terpenes. After review, the research perspectives of CHM on TGF-[Formula: see text]1 inhibition in PF were further discussed. This review hopes that revealing the inhibiting effects of CHM on TGF-[Formula: see text]1-mediated cellular processes of PF can promote CHM to be better understood and utilized, thus transforming the therapeutic activities of CHM into practice.

Abstract
BACKGROUND A novel coronavirus (SARS-CoV2) outbreak in more than 200 countries recently caused viral pneumonia that was extremely infectious and pathogenic. The Chinese government proposes that both Traditional Chinese medicine (TCM) and Western medicine can be used in combination to treat pneumonia caused by SARS-CoV2, and TCM effectively provides continuous prevention and treatment. METHODS The present review analyzes and summarizes the prevention and treatment of the novel coronavirus disease (COVID-19) with TCM. A classified analysis of the efficacy and advantages of TCM for the prevention and treatment of COVID-19 was performed, and the mechanisms of TCM in treating COVID-19 are summarized. RESULTS TCM is effective in preventing COVID-19, and medical staff can prevent an iatrogenic infection by taking a decoction made based on the principles of TCM. As of March 13, 2020, new cases of COVID-19 in China have decreased in number to single digits. TCM's curative effect was outstanding, with a national participation rate of over 90%. More than 70,000 people were cured of COVID-19 and discharged from the hospital. Only approximately 10,000 patients are currently being treated, and the total treatment time is approximately 2 months. CONCLUSIONS TCM is currently the best choice for the treatment and prevention of COVID-19, and it is expected that it will be promoted by countries around the world.

Research Progress in Chinese Herbal Medicines for Treatment of Sepsis: Pharmacological Action, Phytochemistry, and Pharmacokinetics.
Cheng, C, Yu, X
International journal of molecular sciences. 2021;(20)
Abstract
Sepsis is a life-threatening organ dysfunction caused by a dysregulated host response to infection; the pathophysiology of sepsis is complex. The incidence of sepsis is steadily increasing, with worldwide mortality ranging between 30% and 50%. Current treatment approaches mainly rely on the timely and appropriate administration of antimicrobials and supportive therapies, but the search for pharmacotherapies modulating the host response has been unsuccessful. Chinese herbal medicines, i.e., Chinese patent medicines, Chinese herbal prescriptions, and single Chinese herbs, play an important role in the treatment of sepsis through multicomponent, multipathway, and multitargeting abilities and have been officially recommended for the management of COVID-19. Chinese herbal medicines have therapeutic actions promising for the treatment of sepsis; basic scientific research on these medicines is increasing. However, the material bases of most Chinese herbal medicines and their underlying mechanisms of action have not yet been fully elucidated. This review summarizes the current studies of Chinese herbal medicines used for the treatment of sepsis in terms of clinical efficacy and safety, pharmacological activity, phytochemistry, bioactive constituents, mechanisms of action, and pharmacokinetics, to provide an important foundation for clarifying the pathogenesis of sepsis and developing novel antisepsis drugs based on Chinese herbal medicines.

Abstract
BACKGROUND Coronavirus disease-2019 (COVID-19) caused by infection with severe acute respiratory coronavirus-2 (SARS-CoV-2) has been spreading rapidly throughout China and in other countries since the end of 2019. The World Health Organization (WHO) has declared that the epidemic is a public health emergency of international concerns. The timely and appropriate measures for treating COVID-19 in China, which are inseparable from the contribution of traditional Chinese medicine (TCM), have won much praise of the world. PURPOSE This review aimed to summarize and discuss the essential role of TCM in protecting tissues from injuries associated with COVID-19, and accordingly to clarify the possible action mechanisms of TCM from the perspectives of anti-inflammatory, antioxidant and anti-apoptotic effects. METHODS Electronic databases such as Pubmed, ResearchGate, Science Direct, Web of Science, medRixv and Wiley were used to search scientific literatures. RESULTS The present review found that traditional Chinese herbs commonly used for the clinical treatment of organ damages caused by COVID-19, such as Scutellaria baicalensis, Salvia miltiorrhizaSalvia miltiorrhiza, and ginseng, could act on multiple signaling pathways involved in inflammation, oxidative stress and apoptosis. CONCLUSION TCM could protect COVID-19 patients from tissue injuries, a protection that might be, at least partially, attributed to the anti-inflammatory, antioxidant and anti-apoptotic effects of the TCM under investigation. This review provides evidence and support for clinical treatment and novel drug research using TCM.

Hines, CB
The Nursing clinics of North America. 2021;(1):91-107
Abstract
Fever is a natural body defense and a common symptom of disease. Herbs have been used for thousands of years to treat fever. Many herbs have anti-inflammatory properties. Some are useful in reducing the release of cytokines and mediators of inflammation, whereas others work as natural aspirins to inhibit cyclooxygenase. In addition, herbs have known antipathogenic properties and can be effective in the treatment of infection from numerous microorganisms. Last, in traditional Chinese medicine, herbs are used to restore imbalances between the nonpathogenic and the pathogenic clearing interior heat and treating heat patterns in a variety of ways.

Abstract
Advances in immunotherapy have revolutionized treatments in many types of cancer. Traditional Chinese Medicine (TCM), which has a long history of clinical adjuvant application against cancer, is emerging as an important medical resource for developing innovative cancer treatments, including immunotherapy. In this study, we developed a quantitative and systems pharmacology-based framework to identify TCM-derived natural products for cancer immunotherapy. Specifically, we integrated 381 cancer immune response-related genes and a compound-target interaction network connecting 3273 proteins and 766 natural products from 66 cancer-related herbs based on literature-mining. Via systems pharmacology-based prediction, we uncovered 182 TCM-derived natural products having potential anti-tumor immune responses effect. Importantly, 32 of the 49 most promising natural products (success rate = 65.31%) are validated by multiple evidence, including published experimental data from clinical studies, in vitro and in vivo assays. We further identified the mechanism-of-action of TCM in cancer immunotherapy using network-based functional enrichment analysis. We showcased that three typical natural products (baicalin, wogonin, and oroxylin A) in Huangqin (Scutellaria baicalensis Georgi) potentially overcome resistance of known oncology agents by regulating tumor immunosuppressive microenvironments. In summary, this study offers a novel and effective systems pharmacology infrastructure for potential cancer immunotherapeutic development by exploiting the medical wealth of natural products in TCM.

Ho, VW, Tan, HY, Guo, W, Li, S, Wang, N, Meng, W, So, TH, Yu, EC, Feng, Y
The American journal of Chinese medicine. 2021;(7):1557-1575
Abstract
Breast cancer is currently the most common cancer in women, and it accounts for 11.6% of all cancer diagnoses in 2018. Breast cancer patients frequently resort to alternative medicine in addition to conventional Western therapy. This study is to evaluate clinical effectiveness of Chinese herbal medicine (CHM) on breast cancer by conducting meta-analyses on 81 randomized controlled trials (RCTs) with a total of 7215 subjects from eight databases. All RCTs compared patients using Western therapy alone and those using additional CHM therapy to evaluate the difference of primary (tumor response, mean time to progression (mTTP), overall survival (OS) and progression free survival (PFS)) and secondary outcome measures (tumor markers). Results showed that under the RECIST1.1 criteria, 52% patients with additional CHM therapy (67%, under WHO criteria) achieved either a complete response (CR) or a partial response (PR), compared to 38% patients with Western therapy alone (53%, under the WHO criteria). The risk ratio was 1.31 ([Formula: see text] < 0.00001, 95% CI = 1.15-1.50) for patients with CHM plus Western therapy and 1.25 ([Formula: see text] < 0.00001, 95% CI = 1.18-1.98) for those with Western therapy. Moreover, patients with complementary CHM therapy were associated with an mTTP of 2.79 months longer ([Formula: see text] < 0.00001) and an OS of 1.90 months longer ([Formula: see text] < 0.00001); they also had an increase in 3-year PFS ([Formula: see text]= 0.002), 2- ([Formula: see text]= 0.0002) and 5-year ([Formula: see text]= 0.006) OS rates. Therefore, complementary CHM therapy might demonstrate clinical benefits for breast cancer patients in terms of tumor response and survival. Clinical studies with further stratification of tumor stages and intervention types are highly warranted.

Therapy to Obese Type 2 Diabetes Mellitus: How Far Will We Go Down the Wrong Road?
Heng, XP, Li, XJ, Li, L, Yang, LQ, Wang, ZT, Huang, SP
Chinese journal of integrative medicine. 2020;(1):62-71
Abstract
Traditional glucose-lowering chemical agents, including various types of insulin and insulin secretagogues, insulin sensitizers, gliptins, etc., are based on diabetic pathogenesis of insulin resistance (IR) and islet insufficiency. Numerous evidence-based medical studies have shown that these traditional hypoglycemic chemical agents do not provide cardiovascular benefit to patients with type 2 diabetes mellitus (T2DM) and may even increase the risk of all-cause mortality. Based on research evidence published to date, these studies show that overload of energy could increase the incidence and prevalence of T2DM, and reduction in the heat load can significantly reduce the incidence of T2DM. Therefore, the essence of T2DM is heat overload, meaning heat overload is the etiology of obese T2DM. At the same time, results of numerous studies show that heat overloading is the cause of IR. IR and islet dysfunction are protective factors in intervening with heat overload. These drugs, which are based on the mechanisms of IR and islet insufficiency, increase caloric reserve and cause or worsen obesity, which is equivalent to exacerbating the basic etiology and the cardiovascular risk factor of T2DM. Thus, a reasonable strategy for prevention and treatment of obese T2DM appears to promote the negative balance of calories and the elimination of caloric reserves. Chinese herbal medicines can promote negative balance of heat in many aspects, which can bring new hope for prevention and treatment of T2DM.
