Chile es un país que enfrenta un envejecimiento poblacional acelerado, y con ello cambios en la estructura demográfica, epidemiológica y asistencial, donde la salud sexual de las personas mayores es un área emergente a nivel social y en los sistemas de salud. Esta investigación tiene por objetivos identificar aspectos generales de la sexualidad en las personas mayores, y conocer contenidos educativos entregados a este grupo con tecnologías digitales. Para ello, se propuso una revisión de literatura científica que buscó investigaciones en la materia entre el 1 de enero de 2018 y el 31 diciembre de 2022, en las bases de datos, A partir de ello se analizaron los artículos encontrados y la información emergente. Se encontraron 1573 artículos de los cuales se incluyeron 21 trabajos, 11 con metodología cualitativa, 6 cuantitativa y 4 mixta. Además, 9 trataron el área de sexualidad y 12 respecto de innovaciones tecnológicas en personas mayores. Se aprecia que la sexualidad es un tema creciente a nivel mundial, que arrastra idearios socioculturales asociados a visiones dogmáticas y a mitos, con discriminación hacia este grupo de edad, sobre todo si pertenecen a minorías sexuales. También se observa en este grupo de interés un mejor acceso a nuevas tecnologías digitales para acceder a capacitación, integración social y atención oportuna en salud. La evidencia científica demuestra que la sexualidad de las personas mayores es un tema de interés mundial, invisibilizado, con baja formación y capacitación del personal sanitario. Este personal no educa ni resuelve estos motivos de consulta en forma tradicional o con nuevas tecnologías digitales en salud.
Chile is facing an increasingly aging population and, with it, changes in its demographic, epidemiological, and healthcare structure. As a result, the sexual health of the elderly is an emerging area at the social level and in healthcare systems. This research aims to identify general aspects of sexuality in the elderly and learn about educational content delivered to this group using digital technologies. To do this, we proposed a review of scientific literature on the subject between January 1st, 2018, and December 31st, 2022, in the databases Web of Science, MEDLINE/PubMed, LILACS, Cochrane, Scopus, and Google Scholar. The articles found, and the emerging information was analyzed. A total of 1573 articles were found, of which 21 papers were finally included, 11 with qualitative methodology, six quantitative, and four mixed. In addition, nine addressed the area of sexuality, and 12 focused on technological innovations for the elderly. Sexuality is a growing topic worldwide, carrying with it sociocultural beliefs associated with dogmatic opinions and myths, with discrimination against this age group, especially if they belong to sexual minorities. This group also has better access to new digital technologies that facilitate access to training, social integration, and timely healthcare. Scientific evidence shows that the sexuality of the elderly is a topic of global interest, invisibilized, with low education and training of healthcare workers. The latter are neither informed nor able to solve the reasons for consultation in the traditional way or with new digital health technologies.

El cáncer causa millones de muertes a nivel mundial por lo que su registro es fundamental, existiendo registros clínicos, hospitalarios y poblacionales. Estos últimos son el estándar de oro para la información sobre incidencia y supervivencia de cáncer en una región definida. En Chile se cuenta con cinco registros poblacionales ubicados en ciertas zonas del país. El Registro Nacional del Cáncer chileno surge como un desafío para conformar una herramienta transversal a los tres tipos de registro con la finalidad de, al menos, conocer la cantidad de casos por tipo de cáncer. Su diseño implicó un despliegue de acciones orientadas a lograr consensos entre diversos actores respecto de la información, validación y eventos necesarios de registrar. Se identificaron cuatro etapas en el proceso de atención y el registro: sospecha de diagnóstico, confirmación morfológica (biopsia), resolución clínica (comité oncológico incluyendo la indicación de tratamiento), tratamiento y seguimiento oncológico. A su vez, el desarrollo de la plataforma (años 2018 a 2021) implicó levantamiento de información y acuerdos sobre los requerimientos para el co-diseño del registro, incluyendo un exitoso pilotaje con más de 20 establecimientos de salud del sector público y privado con registro de cerca de 7500 casos de cáncer. El despliegue y uso del Registro Nacional de Cáncer a nivel nacional depende de la autoridad sanitaria. Se trata de un sistema de información que recolecta, almacena, procesa y analiza de forma continua y sistemática datos sobre todos los casos y tipos de cánceres que ocurren en el país. En este trabajo se presenta el diseño y desarrollo de la herramienta, los desafíos abordados, sus fortalezas y debilidades.
Cancer causes millions of deaths worldwide, making its registration essential. There are clinical, hospital, and population-based registries in place. The latter is the gold standard for information on cancer incidence and survival in a defined region. Chile has five population-based registries located in specific areas of the country. The Chilean National Cancer Registry emerged with the challenge of creating a tool encompassing all three types of registries to identify the number of cancer cases by type. Its design involved a series of actions to achieve consensus among various actors regarding information, validation, and events to be registered. Four stages were identified in the care and registration process: suspected diagnosis, morphological confirmation (biopsy), clinical resolution (oncology committee, including treatment recommendations), treatment, and oncological follow-up. The platform's development (from 2018 to 2021) involved gathering information and agreements on the requirements for co-designing the registry, including a successful pilot program with over 20 public and private healthcare facilities that recorded nearly 7500 cancer cases. The deployment and use of the National Cancer Registry at a national level depends on the healthcare authority. It is an information system that continuously and systematically collects, stores, processes, and analyzes data on all cancer cases and types occurring in the country. This work presents the design and development of the tool, the challenges addressed, as well as its strengths and weaknesses.

ABSTRACT
In recent years, polysaccharides have received much attention because of their high safety and good immunological activity. The study of polysaccharide in vivo process is a key scientific problem that needs to be solved for polysaccharide drug development. Some progress has been made in the field of polysaccharide pharmacokinetics and immunomodulation. However, due to the lack of both chromogenic and light-absorbing groups and the complex molecular structure of polysaccharides, the in vivo processes and immunomodulatory mechanisms of polysaccharides have been slow to be investigated. The effective combination of multiple techniques can break the bottleneck of difficult tracing and unknown immunomodulatory mechanism of polysaccharides in vivo, and promote the development and utilization of polysaccharides. In this paper, we systematically summarize the key techniques in the study of polysaccharide in vivo processes and immunomodulatory mechanisms in order to provide technical references and research ideas for the study of polysaccharide in vivo processes and immunomodulatory mechanisms.
ABSTRACT
Needle-free injection technology (NFIT) refers to the drug delivery systems in which drugs are propelled as high-speed jet streams using any of the pressure source to penetrate the skin to the required depth. NFIT is a promising drug delivery system as it enables the injection of liquids, powders, and depot/projectiles, and has the advantages of preventing needle stick accidents, improving drug bioavailability, eliminating needle-phobia, increasing vaccine immunity, simplifying operations and is convenient for patients to use. NFIT and its research background, the structure and classification of needle-free jet injectors (NFJI), drugs that can be delivered using NFJI and the factors affecting the injection effect are comprehensively reviewed in this paper. The limitations and potential development directions are summarized to provide a theoretical basis for the application and development of NFIT.

ABSTRACT
During the treatment of non-small cell lung cancer ( NSCLC) , many patients have developed drug resistance due to the use of targeted EGFR inhibitors. The main reasons for drug resistance are EGFR site mutations and bypass activation. Activation of ALK pathway is one of the major types of bypass activation. A recent authoritative study indicates that ALK is closely related to immunotherapy. This article reviews the treatment of ALK in tumors from three aspects: the structure and physiological function of ALK, the small molecule inhibitor of ALK, the biological function of ALK and its related treatment methods for NSCLC, and prospects future directions for better application of ALK in the treatment of NSCLC.
ABSTRACT
Aim To explore the molecular mechanism of Selaginella moelledorffii Hieron. in the treatment of laryngeal cancer. Methods According to the relevant literature reports, the chemical constituents of S. moellendorffii were obtained, and the active ingredients were screened out through the SwissADME database, and the targets were screened through the PharmMapper database. The laryngeal cancer-related targets were collected by searching OMIM and other databases, and the Venny 2.1.0 online platform was used to obtain the intersection of the two. Protein interaction analysis of the potential targets was performed using the STRNG platform. GO functional analysis and KEGG pathway analysis was carried out using DAVID database. Visual networks were built with Cytoscape 3.8.0 software. Molecular docking was validated by SYBYL-X 2. 0 software. MTT method, Hoechst 33258 staining method and Western blotting were also used for validation. Results At the molecular level, a total of 110 active ingredients of S. moellendorffii and 82 drug targets were screened out, 1,608 targets related to laryngeal cancer, and intersection of 34 targets. GO analysis yielded 135 entries, and KEGG analysis yielded a total of 61 pathways. Molecular docking results showed that the 11 key active ingredients such as 2", 3"-dihydrooch-naflavone wood flavonoids and 4 core target proteins such as MAPK1 had 95. 5% of good docking activity. At the cellular level, SM-BFRE was screened for its strongest inhibitory effect on laryngeal cancer cell proliferation through MTT assay. Furthermore, Hoechst 33258 staining showed that the decrease in Hep-2 cell viability produced by SM-BFRE was related to cell apoptosis. Finally, Western blot verified that SM-BFRE inhibited PI3K/Akt/NF through inhibition- K B/COX-2 pathway to induce apoptosis in laryngeal cancer cells. Conclusions To sum up, it fully reflects the multicomponent, multi-target, and multi-channel synergistic effect of S. moellendorffii in the treatment of laryngeal cancer, and provides a theoretical reference for further elucidation of the mechanism of action of S. moellendorffii in the treatment of laryngeal cancer.
ABSTRACT
OBJECTIVE To rapidly assess the efficacy， safety and cost-effectiveness of novel highly selective Bruton’s tyrosine kinase （BTK） inhibitor zanubrutinib in the treatment of chronic lymphocytic leukemia （CLL）， small lymphocytic lymphoma （SLL） and mantle cell lymphoma （MCL）. METHODS Retrieved from PubMed， Cochrane Library， CNKI， Wanfang database， VIP， and health technology assessment （HTA） websites， systematic reviews/meta-analyses， randomized controlled trials （RCTs）， pharmacoeconomic studies and HTA reports related to zanubrutinib were collected from the database/website establishment to July 2023. The literature was screened according to inclusion and exclusion criteria， and its quality was assessed by using relevant evaluation tools. Data extraction was presented by qualitative description. RESULTS A total of 5 literature were included， comprising of 3 RCTs and 2 cost-effectiveness analyses. In terms of efficacy， compared with the control group， zanubrutinib treatment resulted in significantly longer progression-free survival （P＜0.05） and a higher overall response rate （P＜0.05）. However， there was no statistical significance in overall survival between 2 groups （P＞0.05）. In terms of safety， zanubrutinib had lower incidence of cardiac adverse events， incidence of major bleeding events， and drug discontinuation rate due to adverse drug events， compared to first-generation BTK inhibitors ibrutinib； but the risk of bleeding events caused by zanubrutinib was still higher， compared to traditional chemoimmunotherapy （bendamotine+rituximab）. In terms of cost-effectiveness， zanubrutinib was found to be cost-effective in the treatment of recurrent or refractory MCL， compared to ibrutinib. CONCLUSIONS Zanubrutinib demonstrates sound efficacy and safety in patients with CLL/SLL and MCL patients. Furthermore， it exhibits economic advantages for patients with relapsed or refractory MCL.
ABSTRACT
@#Transcatheter edge-to-edge repair (TEER) for mitral regurgitation (MR) is known as M-TEER. Its strengths include: precise targets and fewer implants; simple and clear principles for catheterization; originating from dependable medical concepts and broad applicability. Furthermore, TEER offers advantages in real-time hemodynamic and effectiveness measurement throughout the procedure over surgical edge-to-edge repair (SEER). When it comes to patients with degenerative mitral regurgitation , M-TEER should aim to deliver more optimum procedural outcomes. In functional mitral regurgitation, a modest transvalvular gradients or moderate residual shunt can be tolerated with M-TEER, which reduces the risk of problems and has no bearing on the patient's prognosis.

ObjectiveTo study domestic and international policies and core areas related to assistive technology services for children with disabilities, to explore the application of assistive technology for children with special needs in the educational context. MethodsBased on the relevant policies and theoretical frameworks of policies on assistive technology services of United Nations, World Health Organization (WHO) and China, the policy frameworks and core areas of assistive technology in the educational context were analyzed using the theories of the six elements of the WHO assistive technology service system and the 5P service model, as well as the international and domestic classifications and directory lists of assistive technologies. ResultsInternational Classification of Functioning, Disability and Health (ICF) gave the definition and classification of assistive technology in educational scenarios. With the Convention on the Rights of Persons with Disabilities (CRPD) as the core and the Assistive Technology for Children with Disabilities (ATD) strategy as the centerpiece of the international policy, the core areas of assistive technology application in educational settings were established with the 5P Model, consisting of five related areas, namely individuals, policies, products, practitioners and service delivery, based on the six elements of the WHO assistive technology service system, namely leadership and governance, financing, human resources for health, service delivery, medical technology and health information system. The ecosystem focused on people, policies, products, practitioners and services that promote access to and use of assistive technology. ConclusionThe policy and core areas for the application of assistive technology in educational contexts are formed on the basis of ICF, with the CRPD at the core, and the strategy of ATD, to define scientifically the definition; and promote assistive technology services for children with disabilities from the perspective of the right to comprehensive, efficient, and child-centered development, to provide usable, accessible, affordable, adaptable, acceptable and quality assistive technology services to ensure that children with disabilities enjoy equal and quality education, and to improve the quality of life and well-being. A human-centered assistive technology ecosystem can be established using 5P Model, to innovate and develop assistive technology services for children with disabilities.
ABSTRACT
Scientific misconduct of researchers causes great waste of academic resources and academic life, which is not only related to the vigorous development of a country’s scientific undertaking, but also directly affects the reputation of the country in the field of scientific research. Based on the analysis of the causes of scientific misconduct of medical researchers in China, this paper comprehensively summarized a series of mature experiences of extraterritorial medical field in preventing scientific misconduct, and put forward corresponding and reasonable countermeasures and suggestions for China’s scientific research governance from three aspects: establishing an effective governance structure based on the normative framework, clarifying the definition standards of scientific research dishonesty in laws and regulations, and formulating good prevention procedures in a healthy academic environment, in order to promote the healthy development of scientific research in China’s medical field and further promote the innovation and progress of medical science and technology.
