Effect of polymer nanoparticles on atherosclerotic lesions and the associated mechanisms: a review / 生物工程学报

Polymer nanoparticles generally refer to hydrophobic polymers-based nanoparticles, which have been extensively studied in the nanomedicine field due to their good biocompatibility, efficient long-circulation characteristics, and superior metabolic discharge patterns over other nanoparticles. Existing studies have proved that polymer nanoparticles possess unique advantages in the diagnosis and treatment of cardiovascular diseases, and have been transformed from basic researches to clinical applications, especially in the diagnosis and treatment of atherosclerosis (AS). However, the inflammatory reaction induced by polymer nanoparticles would induce the formation of foam cells and autophagy of macrophages. In addition, the variations in the mechanical microenvironment of cardiovascular diseases may cause the enrichment of polymer nanoparticles. These could possibly promote the occurrence and development of AS. Herein, this review summarized the recent application of polymer nanoparticles in the diagnosis and treatment of AS, as well as the relationship between polymer nanoparticles and AS and the associated mechanism, with the aim to facilitate the development of novel nanodrugs for the treatment of AS.

Effect of tert-butyl acetate and ethyl butyrate on the dissolution of gallbladder cholesterol stones / 中华肝胆外科杂志

Objective:To compare the effect and biotoxicity of tert-butyl acetate (TBA) and ethyl butyrate (EB) on stone dissolution in vitro.Methods:Ten gallstone samples from patients with multiple gallbladder stones were selected and the cholesterol content was analyzed by HPLC. Stone dissolution tests of TBA and EB were performed on cholesterol gallstone in vitro, and the weight of stone at each time point was recorded, meanwhile, methyl tert-butyl ether (MTBE) was used as the control. The inhibitory effects of MTBE, TBA and EB on proliferation of human normal liver cell line LO2 were analyzed by cell proliferation inhibition assay. Flow cytometry was used to analyze the effects of MTBE, TBA and EB on the early and late apoptosis of LO2 cells, and the changes of reactive oxygen species level in LO2 cells were also analyzed.Results:Of the 10 gallbladder gallstones, 6 were cholesterol gallstones and 4 were non-cholesterol gallstones. Stone dissolution experiment showed that the remaining stones of MTBE, TBA and EB groups were (47.83±3.84)%, (58.12±4.53)% and (75.75±4.61)% 30 minutes later. The remaining stones were (18.38±6.47)%, (33.82±6.22)% and (56.38±3.91)% 90 minutes later. MTBE had the best stone dissolution effect in vitro, the stone dissolution effect of TBA was slightly weaker than MTBE, and the stone dissolution effect of EB was relatively weak in all ( P<0.05). The cell proliferation inhibition experiment showed that the cell viability of the control group, MTBE group and TBA group were (100.00±4.46)%, (96.79±4.32)% and (93.72±3.51)%, respectively, and there were no significant differences among the three groups ( P>0.05). However, the cell viability of EB group (87.57±5.29)% was lower than the above three groups, and the differences were statistically significant ( P<0.001). The early apoptosis and late apoptosis of the control group were (1.67±0.15)% and (1.27±0.06)%, respectively. EB induced early apoptosis (15.90±0.53)% ( P<0.001) and late apoptosis (5.13±0.76)% ( P<0.05). However, MTBE and TBA had no significant effect on cell apoptosis ( P>0.05). Compared with control group, MTBE, TBA and EB all significantly inhibited the level of reactive oxygen species ( P<0.05), and the inhibitory effect of EB was the most obvious. Conclusions:TBA has good stone dissolution effect and biosafety for gallbladder cholesterol stones in vitro, while EB has relatively poor performance. TBA is a potential drug for gallstone dissolution.

Estrategias para la Reanudación de las Actividades Clínico de Laboratorio del Curso de Odontología Ante COVID-19

RESUMEN: A finales del año 2019, el mundo se detuvo debido al escenario pandémico afectado por el virus SARS- CoV-2. La COVID-19 es una enfermedad contagiosa con un alto grado de propagación que ha provocado un brote de contaminación y letalidad en poco tiempo. Con eso, hubo la paralización de varios sectores que provocara una aglomeración, incluyendo todas las Universidades de Odontología. De esa forma, el objetivo del presente estudio fue realizar un estudio bibliográfico acerca de las nuevas reglas de bioseguridad, para la reanudación de las actividades en las clínicas escuela del curso de odontología, frente al nuevo escenario mundial. Presentando las estrategias para reanudar las actividades prácticas clinico-laboratoriales de los cursos de odontología, así como analizar los cambios realizados en infraestructura, nuevos protocolos de bioseguridad y si están de acuerdo con las reglas preconizadas por la Associação Brasileira de Ensino Odontológico (ABENO) y la Organización Mundial de la Salud (OMS). Se realizó una búsqueda bibliográfica de los últimos 2 años, contemplando los descriptores: Bioseguridad, COVID-19, Odontología, Universidades. Se seleccionaron estudios que abordaban el proceso de reanudación de las clases, así como normas de bioseguridad y nuevos protocolos clínico-laboratoriales. Los resultados encontrados identificaron nuevos protocolos de bioseguridad para la atención al paciente en medio de la pandemia de COVID-19, reglas y directrices divulgadas por Ministerios y Asociaciones de salud, así como los impactos causados en los estudiantes de odontología, profesionales del área y pacientes. Con eso, hubo la necesidad de cambios estructurales en las facultades y clínicas odontológicas para facilitar la realización correcta de esos nuevos protocolos. Con esta revisión, se espera que las nuevas normas de bioseguridad, estén siendo aplicadas conforme a los artículos y protocolos abordados en ese estudio, para una reanudación segura de las actividades clínico-laboratoriales en la odontología.

ABSTRACT: At the end of 2019, the world stopped because to the pandemic scenario hit by the SARS-CoV-2 virus. COVID-19 is a contagious infectious disease with a high degree of spread, which caused an outbreak of contamination and lethality in a short time. As a result there was a interruption in several sectors causing an agglomeration, including all the Universities of Dentistry. Thus, the objective of this study was to carry out a bibliographic survey about the new biosafety rules, for the resumption of activities in the school clinics of the dentistry course, in light of the new world scenario. Presenting the strategies for resuming clinical laboratory the practical activities of dentistry courses, as well as analyzing the changes made in infrastructure, new biosafety protocols in accordance with the rules advocated by the Brazilian Association of Dental Education (ABENO) and the Organization World Health Organization (WHO). A bibliographic search of the last 2 years was performed, including the following descriptors: Biosafety, COVID-19, Dentistry, Universities. Studies addressed the process of resuming classes were selected, as well as biosafety standards and new clinical-laboratory protocols. The results identified new biosafety protocols for patient care in the midst of the COVID-19 pandemic, rules and guidelines issued by Ministries and Health Associations, as well as the impacts caused on dentistry students, professionals and patients. Thus, there was a need for structural changes in schools and dental clinics in order to facilitate the correct realization of these new protocols. It is expected that the new biosafety standards addressed in the articles reviewed, are applied for a safe resumption of clinical-laboratory activities in dentistry.

Replication of SARS-CoV-2 in cell lines used in public health surveillance programmes with special emphasis on biosafety

Background & objectives: Polio, measles, rubella, influenza and rotavirus surveillance programmes are of great public health importance globally. Virus isolation using cell culture is an integral part of such programmes. Possibility of unintended isolation of SARS-CoV-2 from clinical specimens processed in biosafety level-2 (BSL-2) laboratories during the above-mentioned surveillance programmes, cannot be ruled out. The present study was conducted to assess the susceptibility of different cell lines to SARS- CoV-2 used in these programmes. Methods: Replication of SARS-CoV-2 was studied in RD and L20B, Vero/hSLAM, MA-104 and Madin–Darby Canine Kidney (MDCK) cell lines, used for the isolation of polio, measles, rubella, rotavirus and influenza viruses, respectively. SARS-CoV-2 at 0.01 multiplicity of infection was inoculated and the viral growth was assessed by observation of cytopathic effects followed by real-time reverse transcription–polymerase chain reaction (qRT-PCR). Vero CCL-81 cell line was used as a positive control. Results: SARS-CoV-2 replicated in Vero/hSLAM, and MA-104 cells, whereas it did not replicate in L20B, RD and MDCK cells. Vero/hSLAM, and Vero CCL-81 showed rounding, degeneration and detachment of cells; MA-104 cells also showed syncytia formation. In qRT-PCR, Vero/hSLAM and MA-104 showed 106 and Vero CCL-81 showed 107 viral RNA copies per ?l. The 50 per cent tissue culture infectious dose titres of Vero/hSLAM, MA-104 and Vero CCL-81 were 105.54, 105.29 and 106.45/ml, respectively. Interpretation & conclusions: Replication of SARS-CoV-2 in Vero/hSLAM and MA-104 underscores the possibility of its unintended isolation during surveillance procedures aiming to isolate measles, rubella and rotavirus. This could result in accidental exposure to high titres of SARS-CoV-2, which can result in laboratory acquired infections and community risk, highlighting the need for revisiting biosafety measures in public health laboratories

Sistema de seguimiento y control eProtect infecciones respiratorias / eProtect respiratory infection monitoring and control system

Las infecciones del tracto respiratorio (ITR) son una de las principales causas de morbilidad y mortalidad en todo el mundo, y representan el 4,4 % de las muertes en todas las edades. A nivel mundial, se han observado disminuciones en la mortalidad causada por las ITR después de la introducción de las vacunas conjugadas contra Haemophilus influenzae tipo b, tos ferina y neumocócica. Sin embargo, las ITR siguen siendo una de las principales causas de mortalidad entre los niños pequeños y los ancianos en los países de ingresos bajos y medios. Se planteó un estudio donde se aplicó un sistema de seguimiento que sirvan para monitorear la vigilancia de las infecciones respiratorias agudas (IRA) en servicios de salud, por laboratorio y en unidades centinela en Perú. Participaron 67 médicos generales o cirujanos de 8 servicios de pediatría. 1453 casos de las IRA fueron de etiología viral, identificando al virus sincitial respiratorio (63,94%), Influenza AH1N1 (16,59%); en el caso de las neumonías bacterianas se aislaron Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pneumoniae y Streptococcus beta hemolyticus. Durante la última década de reforma del sistema de salud, Perú ha hecho de la construcción de su sistema de APS una prioridad. Sin embargo, el sistema se enfrenta actualmente a desafíos para proporcionar atención de alta calidad y valor a la población debido a deficiencias en varias dimensiones. El sistema de APS ayudará a responder a la transición epidemiológica actual y futura epidemia brotes de manera más eficaz(AU)

Respiratory tract infections (RTIs) are one of the leading causes of morbidity and mortality worldwide, accounting for 4.4% of deaths in all ages. Globally, declines in mortality from RTIs have been observed after the introduction of Haemophilus influenzae type b, pertussis, and pneumococcal conjugate vaccines. However, RTIs remain a leading cause of mortality among young children and the elderly in low- and middle-income countries. A study was proposed where a monitoring system was applied to monitor the surveillance of acute respiratory infections (ARI) in health services, by laboratory and in sentinel units in Peru. A total of 67 general practitioners or surgeons from 8 pediatric services participated. 1453 cases of ARI were of viral aetiology, identifying the respiratory syncytial virus (63.94%), Influenza AH1N1 (16.59%); in the case of bacterial pneumonia, Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pneumoniae and Streptococcus beta hemolyticus were isolated. During the last decade of health system reform, Peru has made building its PHC system a priority. However, the system currently faces challenges in providing high quality and value care to the population due to deficiencies in several dimensions. The PHC system will help respond to current epidemiological transition and future epidemic outbreaks more effectively(AU)
