ABSTRACT
Objective:Considering the large amount and poor quality of clinical data, this study aims to explore the establishment of high-quality research database and its role in real-world research by taking the establishment of lymphoma research database as an example.Methods:The expert opinions in the field of lymphoma were collected, and the relevant guidelines and standards were referenced to establish a standard medical knowledge dataset. The electronic diagnosis and treatment data of lymphoma patients treated in Peking University Cancer Hospital from February 2005 to December 2020 were retrospectively extracted, the deep Learning, natural language processing were adopted to build a dynamic intelligent information integration and processing system of " lymphoma database based on electronic medical record system - biological sample information database - extended genetic information database" .Results:The research database not only meets the research needs of clinical researchers, but also realizes the management of traces in the whole process of application, approval, traceability and analysis of hospital medical record data and biological sample data. The total number of research variables in the database was 668, and the structured variables accounted for 46.0%. On December 25, 2021, there were 68 687 lymphoma patients in the database, the ratio of male to female patients was 8/9, and the proportion of patients with ≥3 visits accounted for 23.0%. In addition, researchers can superimpose searches in the database according to the target conditions, display the targeted medical records according to research hypothesis, and then establish a research cohort, conducting statistical modeling, and mining data information.Conclusions:By integrating management processes and using new natural language artificial intelligence technology to establish a high-level evidence-based database, it is helpful for the interconnection and resource sharing of hospital information systems, so as to achieve the purpose of providing reliable and detailed data for real-world research.
ABSTRACT
The discovery of immune checkpoint inhibitors, such as PD-1/PD-L1 and CTLA-4, has played an important role in the development of cancer immunotherapy. However, immune-related adverse events often occur because of the enhanced immune response enabled by these agents. Antibiotics are widely applied in clinical treatment, and they are inevitably used in combination with immune checkpoint inhibitors. Clinical practice has revealed that antibiotics can weaken the therapeutic response to immune checkpoint inhibitors. Studies have shown that the gut microbiota is essential for the interaction between immune checkpoint inhibitors and antibiotics, although the exact mechanisms remain unclear. This review focuses on the interactions between immune checkpoint inhibitors and antibiotics, with an in-depth discussion about the mechanisms and therapeutic potential of modulating gut microbiota, as well as other new combination strategies.

Objective@#To understand the research status of occupational asthma and provide information for related research on occupational asthma in the future.@*Methods@#Papers on occupational asthma published from January 1998 to December 2017 had been retrieved in Web of Science core collection database on 9 October 2018. The data retrieval strategies were set as follows: #1 TS=(occupational AND asthma), #2 TS=(occupational AND asthmas), #3 TS=(occupational asthma OR occupational asthmas), #1 OR #2 OR #3. Three thousand two hundred and twelve publications were analyzed by bibliometric and visualizer.@*Results@#Yearly output of articles in this field had been at a stable high level and annual total citations had been increasing. A significant positive correlation was found between the year and annual total citations (r=0.97, P<0.05). The most productive countries were European countries except the United States and Canada. Our country had few literatures accounting for 1.21 percent of the total and the research on occupational asthma in our country started relatively late which were published mainly from 2013 to 2017. The most studied category and journal were public environmental occupational health and Am J Ind Med respectively. "occupational exposure", "allergy" and "rhinitis" were key words with high frequency.@*Conclusion@#Yearly output of publications of occupational asthma has been at a stable high level. Our country should do more research to provide a scientific basis for further prevention and management of occupational asthma.
ABSTRACT
Emotional and cognitive disorders (EACD),such as depression and anxiety,have become very common in today′s society,seriously affecting human lives and health. Neural plasticity can reflect the anti-stress ability of the nervous system to the internal and external stimulation,and is capable of dynamic changes in structure or function to adapt to environmental changes,as is often manifested in the process of compensation and repair of nerve injuries. EACD is often accompanied by macroscopic and cellular morphological changes in brain tissues and functions. Thus,studies on the mechanisms of neural plasticity will contribute to the treatment of EACD. In this paper ,the role of neural plasticity in the active components of Chinese herbal medicine(ACCHM) is reviewed. The effects of ACCHM on 5-hydroxytryptamine(5-HT)system,and the antioxidant activities and neurotrophic effects of ACCHM are described. ACCHM can affect neural plasticity,playing a neuroprotective role by improving 5-HT levels,reducing oxidative stress in brain cells,and increasing the expression of brain derived neurotrophic factor(BDNF). In summary,one ACCHM could affect neural plasticity through one or more mechanisms. There are interactions between different mechanisms of the same ACCHM. Different ACCHM can play a synergistic effect on the enhancement of neural plasticity because of their different mechanisms.
