Traditional Chinese medicine (TCM), especially Chinese herbal medicines and acupuncture, has been traditionally used to treat patients with cancers in China and other East Asian countries. Numerous studies have indicated that TCM not only alleviates the symptoms (e.g., fatigue, chronic pain, anorexia/cachexia, and insomnia) of patients with cancer and improves their quality of life (QOL) but also diminishes adverse reactions and complications caused by chemotherapy, radiotherapy, or targeted-therapy. Therefore, Chinese herbal medicines and acupuncture and other alternative therapies need to be understood by TCM physicians and other health care providers. This review mainly summarizes the experimental results and conclusions from literature published since 2010, and a search of the literature as been performed in the PubMed, MEDLINE, Web of Science, Scopus, Springer, ScienceDirect, and China Hospital Knowledge Database (CHKD) databases. Some Chinese herbal medicines (e.g., Panax ginseng, Panax quinquefolius, Astragali radix, Bu-zhong-yi-qi-tang (TJ-41), Liu-jun-zi-tang (TJ-43), Shi-quan-da-bu-tang (TJ-48), and Ban-xia-xie-xin-tang (TJ-14)) and some acupuncture points (e.g., Zusanli (ST36), Zhongwan (CV12), Neiguan (PC6) and Baihui (GV20)) that are commonly used to treat cancer-related symptoms and/or to reduce the toxicity of chemotherapy, radiotherapy, or targeted-therapy are highlighted and summarized. Through a review of literature, we conclude that TCM can effectively alleviate adverse gastrointestinal reactions (including diarrhea, nausea, and vomiting) to these anti-cancer therapies, decrease the incidence of bone marrow suppression, alleviate cardiotoxicity, and protect against chemotherapy-induced peripheral neuropathy and radiation-induced pneumonitis. Moreover, TCM can alleviate epidermal growth factor receptor-tyrosine kinase inhibitor (EGFR-TKI)-related acneiform eruptions, diarrhea, and other adverse reactions. The hope is that this review can contribute to an understanding of TCM as an adjuvant therapy for cancer and that it can provide useful information for the development of more effective anti-cancer therapies. However, more rigorously designed trials involving cancer treatment must be conducted in the future, including complete quality control and standardized models at the cellular, organic, animal and clinical levels, in order to study TCM in multiple forms and at multiple levels.

Obesity and related metabolic diseases have become one of the world's most serious public health problems. Bariatric surgery has gone through a long and difficult development process, from being rejected to gradually recognized, then widely accepted, and finally becoming the "gold standard" for the treatment of morbid obesity with metabolic diseases. Procedures have constantly been improving and evolving as the concept of bariatric surgery has been reappraised. The comparison and selection of different procedures, the emergence of new technologies and treatment methods, and the in-depth study of the mechanism of metabolic weight loss surgery are effectively promoting the rapid development of bariatric surgery. This article looks at both the 2014 and 2019 editions of the Guidelines for Diagnosis and Treatment of Obesity and Type 2 Diabetes Mellitus from the Chinese Society of Metabolic and Bariatric Surgery (CSMBS), its review the development of bariatric surgery, and it describes surgical indications and contraindications, the mechanism of weight loss, and tailored selection of the surgical procedure in order to serve as a reference.

Onco-cardiology is an emerging field linking cancer with cardiovascular injury. Understanding the mechanism of cardiac injury helps improve the quality of life of cancer survivors. A series of studies on adverse reactions to cancer or oncological treatments has indicated that adverse cardiovascular events related to cancer treatments may occur over a longer period of survival, and even years after therapy has concluded. Current cancer therapies, including chemotherapy, radiotherapy, targeted therapy, and immunotherapy, have been found to have latent cardiovascular toxicity. These toxic effects are often progressive and irreversible and ultimately lead to cardiovascular events such as heart failure, hypertension, coronary heart diseases, arrhythmia, and thromboembolism. Therefore, more emphasis should be placed on revealing the mechanism of cancer treatment-related cardiovascular toxicity. This would help to guide prevention, diagnosis, and treatment of CVDs in cancer survivors.

In Japan, the Law Concerning the Prevention of Infectious Diseases and Medical Care for Patients with Infectious Diseases (the "Infectious Diseases Control Law") classifies infectious diseases as category I-V infectious diseases, pandemic influenza, and designated infectious diseases based on their infectivity, severity, and impact on public health. COVID-19 was designated as a designated infectious disease as of February 1, 2020 and then classified under pandemic influenza as of February 13, 2021. According to national reports from sentinel surveillance, some infectious diseases transmitted by droplets, contact, or orally declined during the COVID-19 epidemic in Japan. As of week 22 (June 6, 2021), there were 704 cumulative cases of seasonal influenza, 8,144 cumulative cases of chickenpox, 356 cumulative cases of mycoplasma pneumonia, and 45 cumulative cases of rotavirus gastroenteritis; these numbers were significantly lower than those last year, with 563,487 cumulative cases of seasonal influenza, 31,785 cumulative cases of chickenpox, 3,518 cumulative cases of mycoplasma pneumonia, and 250 cumulative cases of rotavirus gastroenteritis. Similarly, many infectious diseases transmitted by droplets or contact declined in other countries and areas during the COVID-19 pandemic. One can reasonably assume that various measures adopted to control the transmission of COVID-19 have played a role in reducing the spread of other infectious diseases, and especially those transmitted by droplets or contact. Extensive and thorough implementation of personal protective measures and behavioral changes may serve as a valuable reference when identifying ways to reduce the spread of infectious diseases transmitted by droplets or contact in the future.

The COMmunity Pharamcists ASSist for Blood Pressure (COMPASS-BP) study aimed to assess the effectiveness of lifestyle support programs administered in community pharmacies on hypertension control. This open-label, two-armed parallel group, cluster-randomized controlled trial included 73 pharmacies (clusters) in Japan randomized to a control or intervention group. Eligible hypertensive patients (n = 125), aged 20-75 years, received the intervention (n = 64) or the control treatment (n = 61), as dictated by their pharmacy randomization. Patients in the intervention group received brochures and healthy lifestyle advice from pharmacists using motivational interviewing methods during pharmacy visits over a 12-week period, with their usual pharmacy care. Conversely, the control group just received usual care. The main outcome measure was a change in morning systolic blood pressure (SBP) from baseline to week 12. The intervention group exhibited a decrease in morning SBP that was 6.0 mmHg greater than that of the control group (95% confidence interval [CI]: −11.0 to −0.9, p = 0.021). In a mixed-effect model for repeated measures analysis, the intergroup difference in morning SBP decrease was −4.5 mmHg (95% CI: −8.5 to −0.6, p = 0.024). Our findings indicate that implementation of a lifestyle advice program in pharmacies is feasible and may lead to reduced blood pressure.

The COVID -19 pandemic has had a catastrophic impact on the global economy and the healthcare industry. Unfortunately, the scientific community still hasn't discovered a definite cure for this virus. Also, owing to the unscrupulous use of antibiotics in wake of the current situation, another ongoing pandemic of antimicrobial resistance (AMR) has been entirely eclipsed. However, increased compliance to infection control measures like hand hygiene (both at hospital and community level), and restricted travel might be favorable. It is evident that the AMR strategies will be impacted disproportionately varying with the respective policies followed by the countries and hospitals to deal with the pandemic. The vaccination drive initiated globally has provided a glimmer of hope. In this article, the possible reciprocity between the two contemporaneous pandemics has been addressed. The world needs to be vigilant to punctuate the symphony between these lethal threats to global health. The restraint to combat against AMR will be boosted as our discernment of the problem also changes with the epidemiological interplay becoming more apparent in near future.

The COVID-19 pandemic continues to ravage the world. As many countries have entered the postpandemic period, current efforts to prevent and control COVID-19 have gradually been normalized in many countries. Although the focus is on vaccines to achieve herd immunity, conventional physical containment strategies should be reassessed as part of efforts to prevent and control infectious diseases. Continued respiratory protective measures such as social distancing and the wearing of masks have been extensively accepted by the public in most countries. A point worth noticing is that the activities of influenza and other respiratory diseases have decreased as these strategies have been implemented. Public mobilization and large-scale campaigns to promote health are also important to interrupting the transmission of pathogens. A good example can be found in the achievements of China's Patriotic Public Health Campaign. These practices underscore the importance of enhancing physical containment strategies and public mobilization and management, with support from the legal system, to respond to any potential emerging infectious diseases.

The COVID-19 pandemic caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has resulted in a serious public health burden. As the COVID-19 epidemic in China would coincide with a seasonal outbreak of influenza, there were serious concerns about whether influenza would be aggravated by the SARS-CoV-2 infection and COVID-19 pandemic. This article provides a brief overview of the impacts of the COVID-19 epidemic on influenza activity in China. The percentage of positive influenza tests decreased during the COVID-19 pandemic. During the first stage of the COVID-19 outbreak, the percentage of positive influenza tests reached to a peak of 47.7%. At the second stage, the percentage of positive influenza tests was dramatically decreased from 40.4% to 14.0%. Thereafter, it remains at a low level of less than 6.2%. In addition, the possible causes of this phenomenon have been summarized, including prevention and control measures and ecological competition. Lastly, this article suggests that the public health approach to preventing COVID-19 may also help to control other respiratory infectious diseases. Public health measures need to be maintained even in the later stages of the COVID-19 epidemic.

Enhancement of alternative activation (M2) in microglia is a promising therapeutic target for microglia-mediated neuroinflammation. Shenqi Fuzheng Injection (SFI) is a clinical adjuvant treatment for cancer to reduce the side effects during cancer treatment, including boosting mood and improving appetite. However, the mechanism of SFI's effects on central symptoms is not clear. Therefore, using arginase 1 (Arg1) and transforming growth beta-1 (Tgfb1) as markers for M2 microglia activation, we found that compounds 1, 5, 12, 14, and 15 are the major M2-promoting constituents in SFI, which significantly upregulated Arg1 or Tgfb1 gene expression. Our results suggested that these compounds in SFI may promote M2 microglial activation and have potential uses in modulating microglial activation and alleviating neuroinflammation.

Traditional Chinese medicine (TCM) is a valuable form of medicine with a long history in China. It has played a significant role in the control and prevention of infectious diseases including SARS and H7N9 flu. After the outbreak of COVID-19, China's National Health Commission included TCM in the Diagnosis and Treatment Protocol for COVID-19. During the COVID-19 pandemic, three traditional Chinese medicines (Jinhua Qinggan granules, Lianhua Qingwen medicine, and a Xuebijing Injection) and three TCM preparations (a Qingfei Paidu decoction, a Huashi Baidu decoction, and a Xuanfei Baidu decoction) have been screened for their efficacy against COVID-19. More than 150 trials involving TCMs are registered in the Chinese Clinical Trial Registry (ChiCTR), and those trials cover prevention, treatment, recovery, and illnesses diagnosed in accordance with TCM principles. TCM can effectively alleviate the symptoms of patients with COVID-19, delay the disease's progression from mild to severe or critical, and reduce severe and critical all-cause mortality. The underlying mechanisms of TCM mainly involve action against SARS-CoV-2, anti-inflammatory and immunomodulatory action, and organ protection. The current work provides a brief description of the current status of and issues with TCM to treat this novel infectious disease. The hope is that TCM can help considerably to control this global epidemic.

According to China's Seventh National Census, 18.70% of a total of 1.41 billion people were 60 or older and 13.50% were 65 or older, so China's population is increasingly aging. In conjunction with China's socioeconomic and scientific and technological development and its promotion of medical insurance-related policies, rational medication management for the elderly is a concern in order to control the risk of polypharmacy. This paper summarizes and discusses the following five key issues inherent in rational medication management: i) an increase in serious polypharmacy and the potential risks of medication; ii) a lack of medication consultation service and medication withdraw without healthcare providers' supervision; iii) poor medication compliance among the elderly; iv) insufficient quantity and incompetence of pharmaceutical staffing; and v) limited awareness of pharmaceutical services and lack of trust in the ability of pharmacists. Based on a discussion of factors influencing these issues, suggestions have been put forward in the hopes that China emphasizes rational medication management in order to reduce the risk of polypharmacy and the disease burden of the elderly in China.

The coronavirus disease 2019 (COVID-19) pandemic has resulted in a substantial global public healthcare crisis, leading to the urgent need for effective therapeutic strategies. Neutralizing antibodies (nAbs) are a potential treatment for COVID-19. This article provides a brief overview of the targets and development of nAbs against COVID-19, and it examines the efficacy of nAbs as part of both outpatient and inpatient treatments based on emerging clinical trial data. Assessment of several promising candidates in clinical trials highlights the potential of nAbs to be an effective therapeutic to treat COVID-19 in outpatient settings. Nevertheless, the efficacy of nAbs treatment for hospitalized patients varies. In addition, this review identifies challenges to ending the COVID-19 pandemic, including concerns over nAbs development and clinical use. Resistant variants significantly threaten the availability of nAb-based therapeutics. This review also discusses other approaches that may improve the clinical benefit of neutralizing mAbs.

Since 2011, pharmaceutical companies in Japan have been required to issue two types of documents regarding severe adverse drug reactions reported post-marketing, namely the Rapid Safety Communication Materials for Patients and the Related Materials. However, the adequacy of these documents has not yet been systematically assessed. The aim of this study was to evaluate the adequacy of these two types of materials. The Rapid Safety Communications for Patients were obtained from the Pharmaceuticals and Medical Devices Agency (PMDA) website. The Related Materials were obtained from pharmaceutical companies or the PMDA website. Three assessors independently scored the Rapid Safety Communication for Patients and the Related Materials using the Centers for Disease Control and Prevention Clear Communication Index (CCI). In addition, the contents and descriptions of the materials were analyzed. In total, 13 materials for seven drugs were assessed. Almost all materials contained the "main message" and "call to action". However, the average CCI scores for the Rapid Safety Communication for Patients and Related Materials for Patients were 68.8 and 74.3 (out of 100), respectively. Further, none of the evaluated materials were scored above the CCI threshold score (i.e., ≥ 90%). Descriptions regarding "language", "state of science", and "risk" were not adequate. In particular, the terminology used in materials seemed difficult for patients to understand. In conclusion, the Japanese Rapid Communication Materials for Patients require improvement. Furthermore, a system for evaluating these materials prior to publication should be established.

Fibrodysplasia Ossificans Progressiva (FOP) is a rare congenital intractable disease associated with a mutation in ACVR1 gene, characterized by skeleton malformations. Ascorbic acid (AA) and propranolol (PP) in combination is reported to minimize flare-ups in patients. FOP leukocyte phenotype may possibly be modulated by AA and PP treatment. In this study, expression of 22 potential target genes was analyzed by RT-PCR in peripheral blood mononuclear cells culture (PBMC) from FOP patients and controls to determine effectiveness of the combination therapy. PBMC were treated with AA, PP and AA+PP combination. Basal expression of 12 of the 22 genes in FOP PBMC was statistically different from controls. ACVR1, ADCY2, ADCY9 and COL3 were downregulated while COL1 was upregulated. ADRB1, ADRB2, RUNX2, TNF-α and ACTB, were all overexpressed in FOP PBMC. In control, AA upregulated COL1, SVCT1, ACTB, AGTR2 and downregulated ADCY2. In FOP cells, AA upregulated ACVR1, BMP4, COL1, COL3, TNF-α, ADCY2, ADCY9, AGTR2 and MAS, while downregulated ADBR2, RUNX2, ADCY1, SVCT1 and ACTB. PP increased ADBR1 and decreased RUNX2, TNF-α, AGTR1, ACTB and CHRNA7 genes in treated control PBMC compared to untreated. PP upregulated ADBR1, ADBR2 and MAS, and downregulated TNF-α and ACTB in treated FOP PBMC versus untreated. AA+PP augmented ADRB1 and ADRB2 expressions in control PBMC. In FOP PBMC, AA+PP augmented ACVR1, COL1, COL3, ADBR1, AGTR2 and MAS expression and downregulated ADBR2, RUNX2, ACTB and MRGD. These data show distinct gene expression modulation in leukocytes from FOP patients when treated with AA and or PP.

Pancreatic cancer is known to have the poorest prognosis among digestive cancers. With the development of new chemotherapeutic agents and introduction of multidisciplinary therapy, however, the treatment outcomes for pancreatic cancer have dramatically improved over the past two decades. The keys to successful treatment will be accurate assessment of resectability [resectable (R), borderline resectable (BR) or unresectable (UR)] at the time of diagnosis and prompt adoption of an appropriate multidisciplinary treatment strategy. Prep-02/JSAP-05 trial which is an RCT of upfront surgery versus neoadjuvant chemotherapy using GEM and S-1 (GS) and subsequent surgery for R-PDAC in Japan indicated neoadjuvant chemotherapy had a longer overall survival (OS) than those undergoing upfront surgery (36.7M vs. 26.6M, p = 0.015). In a retrospective multicenter study in Japan reported that in BR-PDAC, median survival time (MST) in the pretreatment group was significantly better than that in the upfront surgery group (25.7 months vs. 19.0 months, p = 0.015) according to a propensity score matching analysis. Another retrospective multicenter study with UR-LA PDAC in Japan reported that conversion surgery was more beneficial for patients with more than 8 months of preoperative therapy than those with less than 8 months of that therapy. Various clinical trials on pancreatic cancer are ongoing, and the results of trials on chemotherapeutic regimens and multidisciplinary treatments will be of further interest.

During the COVID-19 pandemic, frontline nurses have faced extraordinary personal and professional challenges. These challenges have had mental health consequences, and concerning reports of burnout have emerged globally. We conducted a cross-sectional survey at a designated COVID-19 hospital in Shanghai at the peak of the pandemic, i.e. about 2 months after the onset of the outbreak from February to April 2020. Findings revealed burnout in 6.85% of nurses. Of 336 respondents, 87 (25.89%) had a high level of emotional exhaustion, 61 (18.15%) had a high level of depersonalization, and 100 (29.76%) had a low level of personal accomplishment. Burnout can be prevented by offering more support from families and supervisors, paying attention to health monitoring and personal protection, and creating a rational human resource allocation and shift management system. Specific training on infection control and self-protection, mental health guidance, and stress coping techniques must be implemented. As the current health crisis ultimately abates, moving the focus from mental health issues to public health issues, more attention and support at the national and organizational levels are needed to reduce occupational discrimination, nurse autonomy and status need to be promoted, and public health emergency teams need to be created. A positive and fair working environment is essential to effective healthcare delivery.

As the COVID-19 epidemic is still ongoing, a more rapid detection of SARS-CoV-2 infection such as viral antigen-detection needs to be evaluated for early diagnosis of COVID-19 disease. Here, we report the dynamic changes of SARS-CoV-2 viral antigens in nasopharyngeal swabs of COVID-19 patients and its association with the viral nucleic acid clearance and clinical outcomes. Eighty-five COVID-19 patients were enrolled for detection of SARS-CoV-2 viral antigens, including 57 anti-SARS-CoV-2 antibody negative cases and 28 antibody positive cases. The viral antigen could be detected in 52.63% (30/57) patients with SARS-CoV-2 antibody negative at the early stage of SARS-CoV-2 infection, especially in the first 5 days after disease onset (p = 0.0018) and disappeared in about 8 days after disease onset. Viral antigens were highly detectable in patients with low Ct value (less than 30) of SARS-CoV-2 nucleic acid RT-PCT assay, suggesting the expression of viral antigen was associated with high viral load. Furthermore, positive antigen detection indicated disease progression, nine cases with positive antigen (9/30, 30.0%), in contrast to two cases (2/27, 7.40%) (p = 0.0444) with negative antigen, which progressed into severe disease. Thus, the viral antigens were persistent in early stages of infection when virus was in highly replicating status, and viral antigen detection promises to rapidly screen positive patients in the early stage of SARS-CoV-2 infection.

Alcoholism is a global socially significant problem and still remains one of the leading causes of disability and premature death. One of the main signs of the disease is the loss of cognitive control over the amount of alcohol consumed. Among the mechanisms of the development of this pathology, changes in neuroimmune mechanisms occurring in the brain during prolonged alcohol consumption and its withdrawal have recently become the focus of numerous studies. Ethanol consumption leads to the activation of neuroimmune signaling in the central nervous system through many subtypes of Toll-like receptors (TLRs), as well as release of their endogenous agonists (high-mobility group protein B1 (HMGB1), S100 protein, heat shock proteins (HSPs), and extracellular matrix degradation proteins). TLR activation triggers intracellular molecular cascades of reactions leading to increased expression of genes of the innate immune system, particularly, proinflammatory cytokines, causing further development of a persistent neuroinflammatory process in the central nervous system. This leads to death of neurons and neuroglial cells in various brain structures, primarily in those associated with the development of a pathological craving for alcohol. In addition, there is evidence that some subtypes of TLRs (TLR3, TLR4) are able to form heterodimers with neuropeptide receptors, thereby possibly playing other roles in the central nervous system, in addition to participating in the activation of the innate immune system.

Hepatocellular carcinoma (HCC) is a common malignant tumor with a high morbidity and mortality in China and elsewhere in the world. Due to its tumor heterogeneity and distant metastasis, patients with HCC often have a poor prognosis. A surgical treatment such as a radical hepatectomy is still the treatment of choice for patients with HCC in current clinical practice. However, the high rate of recurrence and rate of metastasis after surgery diminishes the survival of and prognosis for these patients. In an era of targeted therapy and immunotherapy, the surgical treatment of HCC must change. This review focuses on the definition, feasibility, and criteria with which to evaluate neoadjuvant therapy for HCC in order to provide a new perspective on surgical treatment of HCC.

Hepatocellular carcinoma (HCC) is one of the most common cancers in the world, and cirrhosis is a risk factor for HCC. Resection is indicated for those unilobar tumors without vascular invasion and metastases in the liver and preserved liver function. Small HCC (< 2 cm) without microvascular invasion is associated with a 5-year recurrence rate as high as 50% to 60%, whereas liver transplantation is indicated for those within the Milan criteria (solitary tumor ≤ 5 cm or two or three nodules ≤ 3 cm) who have decompensated cirrhosis. The 1-, 3-, and 5-year survival rates of living donor liver transplantation for HCC are 85%, 75%, and 70%, respectively. This review summarizes the scientific evidence supporting the clinical practice recommendations for patients with HCC, and it discusses surgical treatment of HCC.
