ABSTRACT

OBJECTIVE To know about the development trend of small nucleic acid drugs in the world ,to provide reference for the research and development of small nucleic acid drug in China. METHODS By searching the academic literature and patents related to small nucleic acid drugs through the Web of Science literature database and PatSnap patent database from Jan. 1980 to Dec. 2021,research and development situation of small nucleic acid drugs were revealed comprehensively by analyzing research enthusiasm,R&D countries ,R&D institutions and technical topics of small nucleic acid drugs. RESULTS & CONCLUSIONS A total of 59 819 documents and 37 645 patent groups were included. The global trend of small nucleic acid drug literature publication and patent application could be divided into three stages. From 2003 to 2021,the research enthusiasm for small nucleic acid drugs continued to increase. The United States ,China,Japan and Germany were the main research and development countries for small nucleic acid drugs. The number of document publications (25 703,15 927 papers)and patent applications (14 240、8 937 groups) in the United States and China were ahead of other countries ,and the research and development activities were relatively strong. Moreover,the number of document publications and patent applications in China in this field had grown rapidly in recent years. The R&D institution with the largest number of publications was the University of California (2 499 papers),the R&D institution with the largest number of patent applications was the American Ionis Corporation (1 378 groups),and the Chinese Academy of Sciences (1 580 papers)had been shortlisted among the top 10 document producing institutions in the world. However ,our country ’s research and development in this field are mostly based on basic research ,and the research on industrial application is slightly insufficient. The research focus in the field of small nucleic acid drugs mainly focuses on nucleic acid sequences and their modification and improvement and drug loading technology.

ABSTRACT

Sarcomatoid renal cell carcinoma is a highly malignant tumor with sarcomatoid dedifferentiation, which has rapid progression, high mortality rate and poor prognosis. Studies have shown that cytoreductive surgery, chemotherapy or targeted therapy are not effective to patients with advanced sarcomatoid renal cell carcinoma. With the further study of pathogenesis and molecular biological characteristics of sarcomatoid renal cell carcinoma, it is found that the expression levels of PD-1 and PD-L1 in it are higher than those of other subtypes, so the combination of immune checkpoint inhibitors and immunotherapy combined with targeted therapy have become the first-line therapy. This article mainly reviews the latest treatments for advanced sarcomatoid renal cell carcinoma, including surgery, chemotherapy, targeted drugs, immunotherapy and so on.

ABSTRACT

Abstract In this study we survey and analyze 300 projects related to marine biodiversity funded by FAPESP from 1972 to 2021, of which 46 were nested in the BIOTA Program. From a unique project in the 1970's, the number gradually increased until 2009, when BIOTA promoted a call on marine biodiversity, which led to a boost in the number of funded projects in the subsequent years. The geographical range of the projects expanded over the years and, from studies based on the coast of São Paulo State, the focus gradually shifted to broader areas of the Brazilian coast, then to other areas of the Atlantic, and eventually became global. The majority of projects focused on coastal benthic organisms living on hard-bottom. In terms of taxa, six groups accounted for about 60% of the projects (viz. Crustacea, Actinopterygii, Mollusca, Chondrichthyes, Cnidaria, and Rhodophyta), but it is observed an increase in the number of groups studied over the decades. The 300 projects refer to a set of 82 different topics, of which the top five are taxonomy, phylogeny, community, "omics", and pollution. The analyses show a long-standing effort in marine biodiversity surveys, with ongoing updated approaches regarding scope and methods. Research on strategic areas is discussed, including deep-sea and marine microbiota. Climate change and the increasing pressure of human activity on the ocean, including pollution, acidification and invasive species, are among the main challenges for the future. Projects producing and using basic research data in an integrative and transdisciplinary way offer multiple perspectives in understanding changes in ecosystem functioning and, consequently, are essential to support public policies for the conservation and sustainable use of marine biodiversity at different scales. UNESCO's Decade of Ocean (starting 2021) is a window of opportunity to strengthen marine research, to promote national and international collaboration, to build up networks involving the public and private sector, but particularly to draw society's attention to the importance of knowing marine environments and using ocean resources in a sustainable way. The advancement of ocean literacy is one of the main legacies for future generations promoted by integrated research programs such as BIOTA-FAPESP.


Resumo Neste estudo levantamos e analisamos 300 projetos relacionados à biodiversidade marinha financiados pela FAPESP entre 1972 a 2021, dos quais 46 foram realizados no Programa BIOTA. De um projeto único na década de 1970, o número foi aumentando gradativamente até 2009, quando o BIOTA promoveu uma chamada sobre biodiversidade marinha, o que impulsionou o número de projetos financiados nos anos seguintes. A abrangência geográfica dos projetos se expandiu ao longo dos anos e, a partir de estudos baseados no litoral do Estado de São Paulo, o foco gradualmente se deslocou para áreas mais amplas da costa brasileira, depois para outras áreas do Atlântico, e acabou se tornando global. A maioria dos projetos se concentrou em organismos costeiros, bentônicos, em substrato consolidado. Em termos de táxons, seis grupos responderam por cerca de 60% dos projetos (Crustacea, Actinopterygii, Mollusca, Chondrichthyes, Cnidaria e Rhodophyta), mas observa-se um aumento no número de grupos estudados ao longo das décadas. Os 300 projetos referem-se a um conjunto de 82 temas diferentes, dos quais os cinco principais são taxonomia, filogenia, comunidade, "ômicas" e poluição. As análises mostram um esforço de longa data em pesquisas de biodiversidade marinha, com abordagens atualizadas em relação ao escopo e métodos. A pesquisa em áreas estratégicas é discutida, incluindo os estudos sobre a microbiota marinha e em águas profundas. As mudanças climáticas e a crescente pressão da atividade humana sobre o oceano, incluindo poluição, acidificação e espécies invasoras, estão entre os principais desafios para o futuro. Projetos de produção e uso de dados de pesquisa básica de forma integrada e transdisciplinar oferecem múltiplas perspectivas de compreensão das mudanças no funcionamento dos ecossistemas e, consequentemente, são essenciais para subsidiar políticas públicas de conservação e uso sustentável da biodiversidade marinha em diferentes escalas. A Década do Oceano da UNESCO (a partir de 2021) é uma janela de oportunidade para fortalecer a pesquisa marinha, promover a colaboração nacional e internacional, construir redes envolvendo os setores público e privado, mas principalmente para chamar a atenção da sociedade para a importância de conhecer os ambientes marinhos e utilizar os recursos oceânicos de forma sustentável. O avanço da "alfabetização" oceânica é um dos principais legados para as gerações futuras promovidos por programas integrados de pesquisa como o BIOTA-FAPESP.

ABSTRACT

Han stephania, also known as Stephania tetrandra, expelling wind, relieve pain and inducing diuresis for removing edema, is a traditional Chinese medicine for treating rheumatic arthralgia. Alkaloids have an important pharmacodynamic basis in S. tetrandra, and tetrandrine is one kind content of bisbenzylisoquinoline alkaloids, which has many biological activities. These activities include anti-tumor in many ways, clinically inhibiting multiple inflammatory factors, preventing and treating liver fibrosis and renal fibrosis and many other kinds of fibrotic diseases, and in addition, tetrandrine could work synergistically with other drugs. In recent years, through in-depth research by scholars at home and abroad, it has been found that tetrandrine has a protective effect on the nervous system and ischemia-reperfusion injury. At the same time, as a calcium ion antagonist, tetrandrine could effectively block the deposition of calcium ions inside and outside the cell. In summary, the application prospect of tetrandrine in clinical practice is very extensive. In this paper, the pharmacological effects of tetrandrine and the possible mechanisms for these effects are summarized, and review its current research progress. It is hoped that the possible application direction of tetrandrine can be revealed more comprehensively, and provide better enlightenment and ideas for clinical application.

ABSTRACT

HBVcccDNA is the first template for HBV to replicate in hepatocytes and the key factor to HBV to continous infect, which can directly reflect HBV′s infections state and replication.The examination of HBVcccDNA is an effective index to evaluate anti-HBV drugs and an objective index to judge wheter HBV infects extrahepatic tissue. cccDNA found in the serum is an important sign of hepatocyte damage at an early stage. There are nested PCR, selective PCR, Southern imprinted hydridization etc.The methods of qualitative detection include real-time PT-PCR, competitive PCR and intruder detection. Currently, there are some deficiencies existing in the clinical method and the examination system of HBVcccDNA has not yet been formed.Further research and exploration are need to be done in order to provide reliable reference for clinical diagnosis and treatment. The level of HBVRNA in serum potentially reflect cccDNA′s existence and transcription in patient′s liver cells.

ABSTRACT

Resumo Este texto, ao adentrar os muitos planos traçados por uma história de pesquisa e formação esculpida numa zona de interferência com a filosofia, em especial com Gilles Deleuze, Henri Bergson e Mikhail Bakhtin, discorre sobre como a temática da cidade vai se tornando expressiva em seu devir experimentação, sugerindo um efeito-labirinto de nós em rede-de-nós, que não para de se bifurcar e, paradoxalmente, também não para de, em nós, se condensar como um efeito-cidade-em-nós. Um encontro (est)ético com cidades construídas por crianças no entrelaçamento do currículo programático escolar e a cidade do cotidiano, tecendo-se em composições narrativas.(AU)


Abstract This text, upon entering the various plans traced by a history of research and development and sculpted in a zone of interference with philosophy, specifically with Gilles Deleuze, Henri Bergson and Mikhail Bakhtin, addresses the manner in which the theme of the city becomes expressive in its becoming experimentation, suggesting a knot of maze-effect in a network-of-knots that does not stop splitting, while paradoxically, it also does not stop condensing, in us, as a city-in-us-effect. An aesthetic encounter with cities built by children in the entanglement of the academic curriculum with everyday city life, thus weaving narrative compositions.(AU)
