BACKGROUND: Our understanding of the correlation between postdischarge cancer and mortality in patients with coronary artery disease (CAD) remains incomplete. The aim of this study was to investigate the relationships between postdischarge cancers and all-cause mortality and cardiovascular mortality in CAD patients. METHODS: In this retrospective cohort study, 25% of CAD patients without prior cancer history who underwent coronary artery angiography between January 1, 2011 and December 31, 2015, were randomly enrolled using SPSS 26.0. Patients were monitored for the incidence of postdischarge cancer, which was defined as cancer diagnosed after the index hospitalization, survival status and cause of death. Cox regression analysis was used to explore the association between postdischarge cancer and all-cause mortality and cardiovascular mortality in CAD patients. RESULTS: A total of 4085 patients were included in the final analysis. During a median follow-up period of 8 years, 174 patients (4.3%) developed postdischarge cancer, and 343 patients (8.4%) died. A total of 173 patients died from cardiovascular diseases. Postdischarge cancer was associated with increased all-cause mortality risk (HR = 2.653, 95% CI: 1.727-4.076, P < 0.001) and cardiovascular mortality risk (HR = 2.756, 95% CI: 1.470-5.167, P = 0.002). Postdischarge lung cancer (HR = 5.497, 95% CI: 2.922-10.343, P < 0.001) and gastrointestinal cancer (HR = 1.984, 95% CI: 1.049-3.750, P = 0.035) were associated with all-cause mortality in CAD patients. Postdischarge lung cancer was significantly associated with cardiovascular death in CAD patients (HR = 4.979, 95% CI: 2.114-11.728, P < 0.001), and cardiovascular death was not significantly correlated with gastrointestinal cancer or other types of cancer. CONCLUSIONS Postdischarge cancer was associated with all-cause mortality and cardiovascular mortality in CAD patients. Compared with other cancers, postdischarge lung cancer had a more significant effect on all-cause mortality and cardiovascular mortality in CAD patients.

Based on the theory of engineering medicine,a consensus which takes the basic medical ethics of harm reduction as the starting point is proposed to addresses the current clinical problems of a wide variety of radiotherapy setup equipments and methods,large differences by principles,and inaccurate setup.The consensus is formed in two aspects.(1)Advocate coordination of multiple setup methods for joint setup;collect,compare,analyze and screen data on setup methods;determine the operational guidelines and methods for joint setup based on the principle of standardized and unified clinical consistency,with a view to achieving the clinical purpose of greatly ensuring the precision of radiotherapy setup and radiotherapy safety without relying on the golden standard.(2)Standardize the operational methods for tracing setup deviations,so that when the difference in setup leads to poor clinical consistency,the cause of deviation can be traced and the effectiveness of different setups can be screened.Based on the concept of engineering medicine,the consensus is expected to standardize the method of radiotherapy setup,realize accurate radiotherapy,improve treatment effect and show medical ethical care.

COVID-19 has been prevalent for three years. The virulence of SARS-CoV-2 is weaken as it mutates continuously. However, elderly patients, especially those with underlying diseases, are still at high risk of developing severe infections. With the continuous study of the molecular structure and pathogenic mechanism of SARS-CoV-2, antiviral drugs for COVID-19 have been successively marketed, and these anti-SARS-CoV-2 drugs can effectively reduce the severe rate and mortality of elderly patients. This article reviews the mechanism, clinical medication regimens, drug interactions and adverse reactions of five small molecule antiviral drugs currently approved for marketing in China, so as to provide advice for the clinical rational use of anti-SARS-CoV-2 in the elderly.

As a recognized rare and highly fatal disease, hereditary angioedema (HAE) is difficult to diagnose and characterized by recurrent edema involving the head, limbs, genitals and larynx, etc. Diagnosis of HAE is not difficult. However, low incidence and lack of clinical characteristics lead to difficulty of doctors on timely diagnosis and correct intervention for HAE patients. Therefore, it is crucial to improve the awareness of this disease and prevent its recurrence. for HAE patients. In view of absent cognition of doctors and the general public on HAE, patients often suffer from sudden death or become disabled due to laryngeal edema which cannot be treated in time. Thus, based on the Internet mobile terminal platform, the team set up an all-day rapid emergency response system which is provided for HAE patients by setting up "one-click help". The aim is to offer optimization on overall management of HAE and designed the intelligent follow-up management to provide timely assistance and specialized suggestion for patients with acute attacks.

The immune checkpoint blockade therapy has profoundly revolutionized the field of cancer immunotherapy. However, despite great promise for a variety of cancers, the efficacy of immune checkpoint inhibitors is still low in colorectal cancer (CRC). This is mainly due to the immunosuppressive feature of the tumor microenvironment (TME). Emerging evidence reveals that certain chemotherapeutic drugs induce immunogenic cell death (ICD), demonstrating great potential for remodeling the immunosuppressive TME. In this study, the potential of ginsenoside Rg3 (Rg3) as an ICD inducer against CRC cells was confirmed using in vitro and in vivo experimental approaches. The ICD efficacy of Rg3 could be significantly enhanced by quercetin (QTN) that elicited reactive oxygen species (ROS). To ameliorate in vivo delivery barriers associated with chemotherapeutic drugs, a folate (FA)-targeted polyethylene glycol (PEG)-modified amphiphilic cyclodextrin nanoparticle (NP) was developed for co-encapsulation of Rg3 and QTN. The resultant nanoformulation (CD-PEG-FA.Rg3.QTN) significantly prolonged blood circulation and enhanced tumor targeting in an orthotopic CRC mouse model, resulting in the conversion of immunosuppressive TME. Furthermore, the CD-PEG-FA.Rg3.QTN achieved significantly longer survival of animals in combination with Anti-PD-L1. The study provides a promising strategy for the treatment of CRC.

Objective:Powders and decocted powders account for about 1/3 in the Catalogue of Ancient Famous Classical Formulas （the First Batch）， and have a very important position. Determination of preparation technology and particle size in the pulverization process is the key step in the research and development of powders and decocted powders following the original methods. However， there are many terms describing the preparation technology and particle size of powders and decocted powders in ancient Chinese medical books， and the parameters are not clear. Due to the lack of unified basis of particle size， the existing research results have not formed a uniform consensus. Based on ancient textual researches and experimental results， this article discusses the particle size of decocted powders and powders. Method:Through textual researches of the preparation technology and particle size of powders and decocted powders and powder classification in the 2020 edition of Chinese Pharmacopoeia， the specifications of pulverized particle size were suggested. In addition， Xiebaisan and Danggui Buxuetang were taken as examples to investigate the influence of different particle sizes （4， 10， 24 mesh） on the preparation process of decocted powders and the obtained decoction. Result:The particle size of 4 mesh was equivalent to that of ancient as big as hemp bean. The contents of index components in Xiebaisan and Danggui Buxuetang with particle size of 4 mesh were higher than that of 10 mesh and 24 mesh， but the particle size of 50 mesh was too fine to be filtered. Conclusion:The suggested particle sizes of powders and decocted powders are recommended as Cumo is the power through 10-mesh sieve， Mo is the power through 24-mesh sieve， Ximo is the power through 80-mesh sieve， as big as hemp bean is the power through 4-mesh sieve and not through 10-mesh sieve.
