Historical Evolution and Modern Research Progress of Processing of Scutellariae Radix / 中国实验方剂学杂志

By consulting ancient herbal books and modern literature， this paper systematically sorted out and researched the processing history， relevant processing norms in recent years， modern processing technology， chemical composition changes of processed products and their pharmacological mechanism of Scutellariae Radix， in order to provide a basis for the further development of Scutellariae Radix decoction pieces. According to the textual research of ancient books， there were many kinds of processing auxiliary materials of Scutellariae Radix， such as wine， vinegar， salt， honey， pig bile and so on， among which the wine processing was the most diverse and detailed， and the processed products such as raw products， stir-fried products， wine-processed products， fried charcoal products were still in use. The modern processing techniques of Scutellariae Radix mainly focus on the processing aspects of softening and slicing， wine processing and charcoal frying， and the research methods are relatively unified. At present， it is found that the changed chemical constituents of Scutellariae Radix after processing are flavonoids， polysaccharides， volatile oils and trace elements， etc. Pharmacological effects of processed products are hemostasis， antibacterial， anti-inflammatory， antioxidant， analgesic and antipyretic， treatment of lung diseases， treatment of colitis， etc. However， in the studies of Scutellariae Radix processing， there is a lack of research on the structural changes of chemical components caused by processing and a comprehensive comparative study on the pharmacological effects of various processed products. Based on this， it is suggested to carry out systematic research on the processing technology to processing mechanism， further explore the relationship between the change rule of material basis and pharmacological action before and after processing of Scutellariae Radix， and deepen the exploration of molecular mechanism and clinical application of processed products of Scutellariae Radix， in order to clarify the scientific connotation of the processing mechanism of Scutellariae Radix， and lay a foundation for the subsequent expansion of the application of Scutellariae Radix decoction pieces and the formulation of processing standards.

Percepción temporal de síntomas de disfagia en una cohorte de pacientes con disfagia orofaríngea neurogénica

Introducción: La disfagia resulta de varios mecanismos fisiopatológicos donde sus síntomas no son estáticos ni homogéneos en las personas, especialmente cuando existe disfagia orofaríngea neurogénica. Objetivo: Conocer la percepción y comportamiento en el tiempo de síntomas de disfagia mediante el instrumento Eating Assessment Tool-10 (EAT-10) en pacientes con disfagia orofaríngea neurogénica, con el fin de visualizar la dinámica clínica de esta forma de disfagia. Metodología: Estudio observacional tipo cohorte en pacientes con disfagia orofaríngea neurogénica de causas neurológicas y neuromusculares, con seguimiento a tres y seis meses y diligenciamiento del EAT-10 al momento basal, tercer y sexto mes. Resultados: Un total de 90 personas con evaluación basal, de las cuales el 56,7 % (51/90) lograron seguimiento al tercer mes y 25,6 % (23/90) al sexto mes. Los síntomas de disfagia con mayor autopercepción en los tres momentos fueron la dificultad para tragar sólidos, sensación de comida pegada en garganta y tos al comer. La odinofagia no fue un síntoma habitualmente percibido. La puntuación total del EAT-10 estuvo entre 16,61 ± 9 y 18,1 ± 9,5 puntos en general. En pacientes con seguimiento completo se observó variación en la autopercepción para tragar líquidos y pastillas. Se observó variación del puntaje al ajustarlo por recepción de terapias. Discusión: Las enfermedades neurológicas y neuromusculares impactan directamente la deglución con gravedad entre leve a profunda, donde la autopercepción de síntomas deglutorios es dinámica, pero con síntomas cardinales de disfagia orofaríngea en el tiempo. Conclusiones: El reconocimiento y seguimiento de síntomas de disfagia deben ser aspectos usuales en la atención de pacientes con enfermedades neurológicas y neuromusculares.

Introduction: Dysphagia results from several pathophysiological mechanisms where its symptoms are not static or homogeneous in people, especially when there is neurogenic oropharyngeal dysphagia. Objective: To know the perception and behavior over time of symptoms of dysphagia using the Eating Assessment Tool-10 (EAT-10) in patients with neurogenic oropharyngeal dysphagia to visualize the clinical dynamics of this form of dysphagia. Methodology: Observational cohort study in patients with neurogenic oropharyngeal dysphagia of neurological and neuromuscular causes with, follow-up at three and six months, and completion of the EAT-10 at baseline, third and sixth month. Results: A total of 90 people with baseline evaluation were included, of whom 56.7% (51/90) achieved follow-up at the third month and 25.6% (23/90) at the sixth month. Symptoms of dysphagia with greater self-perception at all three moments were difficulty swallowing solids, sensation of food stuck in the throat and coughing when eating. Odynophagia was not a commonly perceived symptom. The total score of the EAT-10 was between 16.61±9 and 18.1±9.5 points in general. In patients with complete follow-up, variation in self-perception of swallowing liquids and pills was observed. Variation of the score when adjusting for the reception of therapies. Discussion: Neurological and neuromuscular diseases directly impact swallowing with mild to profound severity, where self-perception of swallowing symptoms is dynamic, but with cardinal symptoms of oropharyngeal dysphagia over time. Conclusions: The recognition and monitoring of dysphagia symptoms should be usual aspects in the care of patients with neurological and neuromuscular diseases.

Evolución de la virulencia de SARS-CoV-2 en Chile

Introducción: La evolución de la virulencia ha despertado el interés de la biología evolutiva por décadas. Se trata de co-evolución entre agentes patógenos y sus hospederos. Se han planteado diferentes hipótesis para la evolución de la virulencia, entre ellas la evolución con un compromiso virulencia-transmisión. Objetivo: Estudiar la evolución de la letalidad y la transmisión del SARS CoV-2 en Chile, con la hipótesis que ha existido un compromiso con disminución de la letalidad y aumento de la transmisión de esta durante la epidemia. Resultados: La letalidad diaria en Chile disminuyó claramente. Aunque no se encontró correlación entre la letalidad diaria y el número reproductivo efectivo, el número reproductivo efectivo máximo asociado a cada variante viral, presentó un aumento claro desde la aparición de la variante γ en adelante (δ y O) en Chile. Conclusión: Este estudio muestra una evolución de la virulencia con un compromiso virulenciatransmisión. Esto puede ser explicado en gran parte por la evolución viral, pero el cambio en letalidad también puede ser afectado por las intervenciones no farmacológicas y farmacológicas realizadas por la población humana.

Background: The evolution of virulence has aroused the interest of evolutionary biology for decades. It is about co-evolution between pathogens and their hosts. Different hypotheses have been put forward for the evolution of virulence, including evolution with a virulence-transmission trade-off. Aim: To study the evolution of the fatality rate and transmission of SARS CoV-2 in Chile, with the hypothesis that there has been a trade-off to a decrease in lethality and an increase in its transmission during the epidemic. Results: The daily fatality rate in Chile clearly decreased. Although no correlation was found between daily fatality rate and effective reproductive number, the maximum effective reproductive number associated with each viral variant showed a clear increase from the appearance of the γ variant onwards (δ and O) in Chile. Conclusion: This study shows an evolution of virulence with a virulence-transmission trade-off. This can be largely explained by viral evolution, but the change in lethality can also be affected by non-pharmacological and pharmacological interventions carried out by the human population.

Introducción: Las complicaciones, asociadas al brote anormal de los terceros molares, es posible evitarlas con la germenectomía de estos dientes. Objetivo: Caracterizar la evolución de la germenectomía de terceros molares en pacientes con diagnóstico cefalométrico de brote anormal. Métodos: Se realizó un estudio observacional, descriptivo y transversal en el Servicio de Cirugía Maxilofacial del Hospital Provincial "Saturnino Lora Torres", desde febrero de 2019 hasta marzo de 2021. Se estudiaron 32 pacientes de 13 a 15 años de edad, interviniéndose quirúrgicamente 78 terceros molares. Las variables fueron edad, sexo, color de la piel, localización y posición del tercer molar; así como las complicaciones trans y posoperatorias y la evolución. Resultados: Entre los 32 pacientes incluidos en el estudio predominó el sexo femenino (62,5 %) y la edad de 14 años (40,6 %). Las complicaciones ocurridas durante la germenectomía fueron más frecuentes en la arcada inferior. Aunque no fueron detectadas diferencias estadísticamente significativas según localización (valor de p>0,05); con 30 transoperatorias para un 38,4 % y 75 posoperatorias para un 96,2 %. Conclusiones: Se evidencia una evolución marcadamente favorable posterior a la germenectomía de terceros molares en la población de pacientes con diagnóstico cefalométrico de brote anormal. En ellos el sangrado transoperatorio y el dolor posoperatorio constituyen las complicaciones a considerar en este tipo de procedimiento quirúrgico.

Introduction: Complications associated with the abnormal eruption of third molars can be avoided with germenectomy of these teeth. Objective: To characterize the evolution of third molar germenectomy in patients with a cephalometric diagnosis of abnormal bud. Methods: An observational, descriptive and cross-sectional study was carried out in the Maxillofacial Surgery Service at Saturnino Lora Torres Provincial Hospital, from February 2019 to March 2021. Thirty two patients aged 13 to 15 years were studied, with 78 third molars undergoing surgery. The variables were age, sex, skin color, location and position of the third molar; as well as trans and postoperative complications and evolution. Results: Among the 32 patients included in the study, the female sex (62.5%) and the age of 14 years (40.6%) predominated. Complications that occurred during germenectomy were more frequent in the lower arch. Although no statistically significant differences were perceived according to location (p value > 0.05); with 30 intraoperative for 38.4% and 75 postoperative for 96.2%. Conclusions: There is evidence of a markedly favorable evolution after germenectomy of third molars in the population of patients with cephalometric diagnosis of abnormal bud. In them, transoperative bleeding and postoperative pain are the complications to consider in this type of surgical procedure.

Síndrome neuroléptico maligno

El síndrome neuroléptico maligno (SNM) es una reacción adversa medicamentosa potencialmente fatal asociada comúnmente a medicamentos antipsicóticos. Este artículo presenta una revisión actualizada sobre el SNM, aborda su epidemiología, factores de riesgo, presentación clínica, posibles mecanismos subyacentes y tratamiento. Se busca mejorar el reconocimiento temprano, diagnóstico y manejo del SNM en el ámbito clínico para reducir su morbimortalidad. La búsqueda de literatura se realizó en PubMed, fueron priorizados ensayos aleatorizados, revisiones sistemáticas, estudios retrospectivos y reportes de caso. La incidencia del SNM ha disminuido en los últimos años, posiblemente debido a una mejor prescripción y titulación de la medicación. Los factores de riesgo incluyen el uso de antipsicóticos de alta potencia, dosis elevadas, incremento rápido de la dosis y uso de antipsicóticos inyectables de depósito. Se han identificado factores ambientales como la deshidratación, sujeción mecánica y temperaturas extremas. Algunas características psicopatológicas, como la agitación psicomotriz y la confusión, también se han asociado al SNM. Los factores hereditarios y los polimorfismos genéticos pueden influir en la susceptibilidad al SNM, pero se requieren estudios adicionales. La fisiopatología del SNM se relaciona con el bloqueo excesivo de los receptores dopaminérgicos, pero otros cofactores y sistemas neurotransmisores también podrían estar involucrados. El cuadro clínico del SNM se caracteriza por cambios en el estado mental, rigidez muscular, hipertermia, síntomas catatónicos y sudoración profusa. Existen diversas formas de tratamiento, desde medidas generales hasta intervenciones farmacológicas.

The Neuroleptic malignant syndrome (NMS) is a potentially fatal adverse drug reaction commonly associated with antipsychotic medications. This article presents an updated review of NMS, addressing its epidemiology, risk factors, clinical presentation, possible underlying mechanisms, and treatment. The aim is to improve early recognition, diagnosis, and management of NMS in the Peruvian clinical setting to reduce morbidity and mortality. The literature search was conducted in PubMed, prioritizing randomized studies, systematic reviews, retrospective studies, and case reports. The incidence of NMS has decreased in recent years, possibly due to better medication prescription and titration. Risk factors include the use of high-potency antipsychotics, high doses, rapid dose escalation, and the use of depot injectable antipsychotics. Environmental factors such as dehydration, mechanical restraint, and extreme temperatures have been identified. Some psychopathological characteristics, such as psychomotor agitation and confusion, have also been associated with NMS. Genetic factors and genetic polymorphisms may influence susceptibility to NMS, but further studies are needed. The pathophysiology of NMS is related to excessive blockade of dopaminergic receptors, but other cofactors and neurotransmitter systems may be involved. The clinical presentation of NMS is characterized by changes in mental status, muscle rigidity, hyperthermia, catatonic symptoms, and profuse sweating. There are various treatment approaches ranging from general measures to pharmacological interventions.

Origen y evolución de la optometría y la óptica en Cuba y en el mundo

Al revisar la historia de la optometría y la óptica se encuentra que ha tenido procesos de cambio y evolución, debido a la preocupación por la salud visual que ha venido deteriorándose al transcurrir de los años. Para mostrar dichos cambios se realizó una revisión teórica-histórica del origen y la evolución de la optometría y la óptica. Se tuvo en cuenta los datos que han sido de avance científico, tecnológico y humanístico, no solo en la antigüedad sino también en la actualidad, los cuales han servido para mejorar el desarrollo de nuestra actividad profesional y consecuentemente al mejoramiento del bienestar social. Fueron innumerables los hombres que enriquecieron nuestros conocimientos con sus aportes, por lo cual se ha necesitado de muchos siglos de lenta y progresiva evolución para llegar a ser lo que es hoy en día, una ciencia con todas las bases de la óptica, la anatomía y la fisiología de la visión la cual se rige por leyes que nos permiten un conocimiento más exacto de ella. El objetivo es valorar el proceso de origen y evolución de la optometría y la óptica en Cuba y el mundo.

When reviewing the history of optometry and optics, it is found that it has undergone processes of change and evolution, due to the concern for visual health that has been deteriorating over the years. In order to show these changes, a theoretical-historical review of the origin and evolution of optometry and optics was carried out. We took into account the data that have been of scientific, technological and humanistic progress, not only in ancient times but also at present, which have served to improve the development of our professional activity and consequently to the improvement of social welfare. There were countless men who enriched our knowledge with their contributions, so it has taken many centuries of slow and progressive evolution to become what it is today, a science with all the bases of optics, anatomy and physiology of vision which is governed by laws that allow us a more accurate knowledge of it. The objective is to evaluate the process of origin and evolution of optometry and optics in Cuba and the world.

Taxonomía de los hongos: un rompecabezas al que le faltan muchas piezas

Los hongos son organismos polifacéticos presentes en casi todos los ecosistemas de la tierra, donde establecen diversos tipos de simbiosis con otros seres vivos. A pesar de ser reconocidos por los humanos desde la antigüedad -y de la cantidad de trabajos que han profundizado sobre su biología y ecología-, aún falta mucho por conocer sobre estos organismos. Algunos de los criterios que clásicamente se han utilizado para su estudio, hoy resultan limitados y hasta cierto punto permiten un agrupamiento de los aislamientos según algunas características, pero generan confusión en su clasificación y, más aún, cuando se pretende comprender sus relaciones genealógicas. Los caracteres fenotípicos no son suficientes para identificar una especie de hongos y, menos aún, para construir una filogenia amplia o de un grupo particular. Hay grandes vacíos que hacen que los árboles generados sean inestables y fácilmente debatidos. Para los profesionales de la salud, parece que la identificación de los hongos hasta niveles inferiores como género y especie es suficiente para elegir el tratamiento más adecuado para su control, comprender la epidemiología de los cuadros clínicos asociados y reconocer los brotes y los factores determinantes de la resistencia a los antimicrobianos. No obstante, la ubicación taxonómica dentro del reino permitiría establecer relaciones filogenéticas entre los taxones fúngicos, facilitando la comprensión de su biología, su distribución en la naturaleza y la evolución de su potencial patogénico. Los avances de las técnicas de biología molecular y las ciencias de la computación en los últimos 30 años han permitido cambios importantes dirigidos a establecer los criterios para definir una especie fúngica y alcanzar una construcción filogenética más o menos estable. Sin embargo, el camino por recorrer aún es largo, y supone un trabajo mancomunado de la comunidad científica a nivel global y el apoyo a la investigación básica.

Fungi are multifaceted organisms found in almost all ecosystems on Earth, where they establish various types of symbiosis with other living beings. Despite being recognized by humans since ancient times, and the high number of works delving into their biology and ecology, much is still unknown about these organisms. Some criteria classically used for their study are nowadays limited, generating confusion in categorizing them, and even more, when trying to understand their genealogical relationships. To identify species within Fungi, phenotypic characters to date are not sufficient, and to construct a broad phylogeny or a phylogeny of a particular group, there are still gaps affecting the generated trees, making them unstable and easily debated. For health professionals, fungal identification at lower levels such as genus and species, is enough to select the most appropriate therapy for their control, understand the epidemiology of clinical pictures associated, and recognize outbreaks and antimicrobial resistance. However, the taxonomic location within the kingdom, information with apparently little relevance, can allow phylogenetic relationships to be established between fungal taxa, facilitating the understanding of their biology, distribution in nature, and pathogenic potential evolution. Advances in molecular biology and computer science techniques from the last 30 years have led to crucial changes aiming to establish the criteria to define a fungal species, allowing us to reach a kind of stable phylogenetic construction. However, there is still a long way to go, and it requires the joint work of the scientific community at a global level and support for basic research.

Comparative histological analysis of cerebellum of representative species of elasmobranchii

SUMMARY: In elasmobranch fishes, variations in gross structural organization of cerebellum has been extensively explored. The basic histological features of cerebellum although conserved in the group but the comparative account on subtle cellular variations is largely underestimated. The present study aims to explore the histological and cellular variations in different layers of cerebellar cortex of the representative elasmobranchs' species belonging to different habitat. Our findings showed that the histological architecture of cerebellar granular layer between the examined species varies noticeably. By and large increase cellular density were observed in all the layers of cerebellum in the representative species of shark compared to ray. The findings were then compared and discussed with reference to their habitat and behavior.

En los peces elasmobranquios, las variaciones en la organización estructural general del cerebelo se han explorado ampliamente. Las características histológicas básicas del cerebelo, aunque se conservan en el grupo, pero la descripción comparativa de las variaciones celulares sutiles es limitada. El presente estudio tiene como objetivo explorar las variaciones histológicas y celulares en diferentes capas de la corteza cerebelosa de las especies representativas de elasmobranquios pertenecientes a diferentes hábitats. Nuestros hallazgos mostraron que la arquitectura histológica de la capa granular del cerebelo entre las especies examinadas varía notablemente. Se observó un gran aumento de la densidad celular en todas las capas del cerebelo en las especies representativas de tiburón en comparación con la raya. Luego, los hallazgos se compararon y discutieron con referencia a su hábitat y comportamiento.

Introducción. Las fugas anastomóticas son una complicación común y crítica en cirugía gastrointestinal, por lo que su identificación y tratamiento temprano son necesarios para evitar resultados adversos. El uso convencional con un valor límite de la proteína C reactiva ha demostrado una utilidad limitada. El objetivo de este estudio fue determinar la utilidad de la medición seriada de la proteína C reactiva en la detección de fugas anastomóticas. Métodos. Revisión prospectiva de base de datos retrospectiva de pacientes sometidos a cirugía abdominal mayor con al menos una anastomosis intestinal. Se midió la proteína C reactiva al tercer y quinto día posoperatorio. Las complicaciones se categorizaron según la clasificación de Clavien-Dindo. La precisión diagnóstica fue evaluada por el área bajo la curva. Resultados. Se incluyeron 157 pacientes, el 52 % mujeres. La edad promedio fue de 63,7 años. El mayor número de cirugías correspondió a gastrectomía (36,3 %), resección anterior de recto (15,3 %) y hemicolectomía derecha (13,4 %). El 25,5 % tuvieron alguna complicación postoperatoria y el 32,5 % (n=13) presentaron fuga en la anastomosis. El aumento de la proteína C reactiva tuvo un área bajo la curva de 0,918 con un punto de corte de aumento en 1,3 mg/L, sensibilidad de 92,3 % (IC95% 78 ­ 100) y una especificidad de 92,4 % (IC95% 88 ­ 96). Conclusiones. El aumento de 1,3 mg/L en la proteína C reactiva entre el día de la cirugía y el quinto día fue un predictor preciso de fugas anastomóticas en pacientes con cirugía abdominal mayor

Introduction. Anastomotic leaks are a common and critical complication in gastrointestinal surgery. Their identification and early treatment are necessary to avoid adverse results, and conventional use with a cutoff value of C-reactive protein has shown limited utility. The objective of this study was to determine the usefulness of serial measurement of C-reactive protein in the detection of anastomotic leaks. Methods. Prospective review of a retrospective database of patients undergoing major abdominal surgery with at least one intestinal anastomosis. C-reactive protein was measured on the third and fifth postoperative days. Complications were classified according to the Clavien-Dindo classification. Diagnostic accuracy was evaluated by the area under the curve.Results. 157 patients were included, 52% were females. The average age was 63.7 years. The largest number of surgeries corresponded to gastrectomies (36.3%), anterior resection of the rectum (15.3%) and right hemicolectomies (13.4%). 25.5% had some postoperative complication and 32.5% (n=13) had anastomosis leaks. The increase in C-reactive protein had an area under the curve of 0.918 with an increase cut-off point of 1.3 mg/L, sensitivity of 92.3% (95% CI 78-100) and specificity of 92.4%. (95% CI 88-96). Conclusions. The 1.3 mg/L increase in C-reactive protein between the day of surgery and the fifth day was an accurate predictor of anastomotic leaks in patients with major abdominal surgery

Evaluation of the follow-up of children treated for congenital syphilis in a municipality in the state of Espírito Santo, when it lacked crystalline penicillin / valiação do acompanhamento de crianças tratadas para sífilis congênita em município do estado do espírito santo em época de falta de penicilina cristalina

Introduction: Syphilis is a sexually transmitted infection caused by the bacterium Treponema pallidum. In Brazil, its incidence has increased, along with the lack of penicillin, the antibiotic of choice for congenital syphilis, from 2014 to 2017. During this period, children were treated with alternative drugs, but to date, data from the scientific literature do not recommend another antibiotic. Objective: To compare the progression, according to the established treatment, and evaluate the follow-up in health care facilities in Vila Velha (Espírito Santo) of children with congenital syphilis aged up to two years, born in Hospital Infantil e Maternidade Alzir Bernardino Alves ­ a reference in neonatology and low-risk pregnancy in the state at the time ­ from 2015 to 2016, when the hospital experienced a greater lack of penicillin. Methods: This is a retrospective cross-sectional observational study based on data from medical records of the hospital and other healthcare facilities in the city. We performed statistical analyses, per health district, of epidemiological and sociodemographic data, as well as those related to visits, their frequency, and clinical profile, according to the follow-up parameters proposed by the Ministry of Health at the time. Results: Medical records of 121 children were evaluated, presenting as the main findings: only 35% of the children completed the follow-up; among those treated with ceftriaxone, 55.2% completed the follow-up, and 100% of the children whose venereal disease research laboratory was greater than that of their mother at birth completed the follow-up. Of the symptomatic children at birth who remained or became symptomatic at follow-up, 58.8% used ceftriaxone. Conclusion: Among symptomatic children at birth, most of those treated with ceftriaxone remained symptomatic at follow-up. The Counseling and Testing Center was the most successful facility in the follow-up of these children. District 5 had the lowest success rate in the follow-up of these patients, and districts 1 and 2 showed the lowest rates of appropriate approach to congenital syphilis during follow-up. (AU)

Evaluating the dissemination of evolutionary biology concepts in medicine

Darwin's theory of evolution, which is based on variation, heredity, and selection, includes all biological fields and spreads to other areas such as philosophy. Medicine is an example of how the evolutionary perspective can greatly improve the understanding of concepts in an area, as human health and pathological conditions are under the effect of evolution. Evolutionary medicine is an emerging paradigm for understanding human heterogeneity, health, and diseases. Nevertheless, there are indications that medical research and practice are only marginally affected by these ideas. Here, we investigate how concepts of biological evolution are employed in medical research. We use a bibliometric approach to look for the presence and frequency of biological evolution-related concepts in medical articles. The distribution of these concepts over the years is analyzed according to the medical specialty and the impact of the journal. Our data showed that: i) only a small percentage of articles in medical journals have an evolutionary perspective; ii) medical journals where these evolution-based articles are published focus on basic science, theoretical medicine, and less frequently, on applied medicine; iii) these articles are mostly from the microbiology, immunology, neurology, psychology, behavior, and oncology fields; and iv) viruses are the most frequently covered microorganisms, followed by bacteria, fungi, and protozoans. The collection of our results, considering the importance of evolutionary medicine in the medical field, highlights the need for a decisive change in perspective in medical research.

Ongoing HIV-1 evolution and reservoir reseeding in two elite controllers with genetically diverse peripheral proviral quasispecies

BACKGROUND Elite controllers (EC) are human immunodeficiency virus (HIV)-positive individuals who can maintain low viral loads for extended periods without antiretroviral therapy due to multifactorial and individual characteristics. Most have a small HIV-1 reservoir composed of identical proviral sequences maintained by clonal expansion of infected CD4+ T cells. However, some have a more diverse peripheral blood mononuclear cell (PBMC)-associated HIV-1 reservoir with unique sequences. OBJECTIVES To understand the turnover dynamics of the PBMC-associated viral quasispecies in ECs with relatively diverse circulating proviral reservoirs. METHODS We performed single genome amplification of the env gene at three time points during six years in two EC with high intra-host HIV DNA diversity. FINDINGS Both EC displayed quite diverse PBMCs-associated viral quasispecies (mean env diversity = 1.9-4.1%) across all time-points comprising both identical proviruses that are probably clonally expanded and unique proviruses with evidence of ongoing evolution. HIV-1 env glycosylation pattern suggests that ancestral and evolving proviruses may display different phenotypes of resistance to broadly neutralising antibodies consistent with persistent immune pressure. Evolving viruses may progressively replace the ancestral ones or may remain as minor variants in the circulating proviral population. MAIN CONCLUSIONS These findings support that the high intra-host HIV-1 diversity of some EC resulted from long-term persistence of archival proviruses combined with the continuous reservoir's reseeding and low, but measurable, viral evolution despite undetectable viremia.

Hémopathies malignes de l'adulte à Kinshasa: analyse documentaire d'une série des cas de 2011 à 2021 / Hematological malignancies in adults in Kinshasa: retrospective serial cases from 2011 to 2021

Contexte et objectif. Les hémopathies malignes (HM) constituent un problème majeur de santé publique en Afrique sub-saharienne où les moyens de prise en charge sont limités. L'objectif de l'étude était de décrire les aspects diagnostiques, thérapeutiques et évolutifs observées dans la prise en charge des HM en milieu hospitalier de Kinshasa. Méthodes. Etude observationnelle historique de type suivi des cas d'HM hospitalisés, dans formations sanitaires de Kinshasa entre les 1er janvier 2011 et 31 décembre 2021. Seuls les patients âgés de plus de 18 ans ont été inclus. Les paramètres d'intérêt étaient englobés les données sociodémographiques, cliniques, biologiques, d'imagerie, du myélogramme, de l'analyse histopathologique des pièces biopsiques ganglionnaires ou extra ganglionnaires, le type de chimiothérapie et de la survie à 6 mois. Les tests de chi-carré et de Student ont comparé respectivement les proportions et les moyennes. L'analyse de Kaplan Meier et la régression de Cox ont respectivement décrit la survie et recherché les facteurs associés à la mortalité à 6 mois. Résultats.Sur 2678 patients suspects d'HM, seuls de 250 patients (9,3%, âge moyen 47,6 ± 15,8 ans, 62,4% d'hommes) ont eu un bilan de confirmation. Les adénopathies périphériques (54 %), la fièvre au long cours (48 %) et la poly transfusion (29 %) étaient les principaux motifs de consultation. Les perturbations hématologiques rencontrées étaient l'anémie (72 %), la thrombopénie (50 %), l'hyperleucocytose ( 0 %) et la leucopénie ( 0 %). Les syndromes lymphoproliferatif (68 %) étaient plus fréquents et répartis en lymphomes non hodgkiniens (50 %), Lymphome hodgkinien (27%) et myélome multiple (15 %). Les leucémies aigues venaient en deuxième position (12 %) suivi des syndromes myélodysplasiques (11 %) et des syndromes myéloprolifératifs (8 %). 61 % des patients ont bénéficié de la chimiothérapie. Durant les 6 premiers mois de prise en charge, la létalité globale était de 58,4 %. Conclusion. En milieu hospitalier de Kinshasa, très peu de patients suspects d'HM bénéficient d'une mise au point complète et de la chimiothérapie. Les adultes jeunes, surtout les hommes, sont très affectés et plus de la moitié d'entre eux décèdent endéans 6 mois. L'amélioration de l'accessibilité à la chimiothérapie et du plateau technique permettra une réduction de la létalité.

Résultats: sur un total de 612 échantillons analysés, 216 cas de tuberculose ont été confirmés par le laboratoire, soit une fréquence de 35,3 %. Notre échantillon était constitué de 138 hommes et 78 femmes, soit un sex-ratio de 1,77. L´âge moyen était de 35,37±18,14 années. La majorité des patients était dans la tranche d´âge comprise entre 21-40 ans. La profession libérale représentait 94,4 % de notre effectif, soit 204 patients. Il y a eu 63,4% des patients souffraient d´une tuberculose pulmonaire dont 70,9 % était guéris. La sérologie VIH était positive chez 6 patients, soit un taux de séroprévalence VIH de 2,77 %. Au total, 27 malades sont décédés sur les 612, soit un taux de mortalité de 4,41 %. C´est la tranche d´âge de malades ages de plus de 60 ans qui a connu une mortalitéélévée, soit 5 cas sur 20 (25 %), suivie de celle des malades ages de moins de 20 ans, 11 cas sur 49 (22,4 %). D´autre part, le résultat a montré un taux de mortalité plus élévé chez les tuberculeux séropositif, 33,3 %, contre 11.9 % chez les séronégatifs. Conclusion: ce rapport montre un taux élevé de tuberculose dans la zone de santé de Kamina ; il confirme le fait que la TB est endémique dans la région.

Introduction: the purpose of this study was to describe the epidemiological, clinical and evolutionary profile of patients with tuberculosis followed in the urban-rural area of Kamina, Democratic Republic of the Congo (DRC). Methods: we conducted a cross-sectional study based on a retrospective analysis of the medical records of patients followed for tuberculosis over the period January 1, 2018 -December 31, 2021. Results: out of 612 samples analysed, 216 cases had received lab confirmation of tuberculosis, reflecting a rate of 35.3%. Our sample consisted of 78 women and 138 men (sex ratio 1.77). The average age of patients was 35,37±18.14 years. The majority of patients were in the age range 21-40 years. Self-employed people accounted for 94.4% of our workforce (204 patients); 63.4% of patients suffered from pulmonary tuberculosis, 70.9% of whom were cured. Serology test for HIV was positive in 6 patients (i.e. an HIV seroprevalence rate of 2.77%). In total, 27 patients out of 612 died, (i.e. a mortality rate of 4.41%). Patients aged over 60 had higher mortality rates (5 out of 20 cases; 25%), followed by patients under 20 (11 out of 49 cases; 22.4%). On the other hand, our results showed a higher mortality rate among HIV-positive patients with tuberculosis (33.3%, compared to 11.9% among HIV-negative patients). Conclusion: this study shows a high rate of tuberculosis in the Kamina health zone, confirming the fact that TB is endemic in the region. There is a need to improve the living conditions of the population and the local health system with regard to the prevention and management of TB in order to reduce morbidity and mortality

Modification of C20 oxidase in tanshinone biosynthesis pathway / 中国中药杂志

Tanshinones are one of the main effective components of Salvia miltiorrhiza, which play important roles in the treatment of cardiovascular diseases. Microbial heterogony production of tanshinones can provide a large number of raw materials for the production of traditional Chinese medicine(TCM) preparations containing S. miltiorrhiza, reduce the extraction cost, and relieve the pressure of clinical medication. The biosynthetic pathway of tanshinones contains multiple P450 enzymes, and the catalytic element with high efficiency is the basis of microbial production of tanshinones. In this study, the protein modification of CYP76AK1, a key P450-C20 hydroxylase in tanshinone pathway, was researched. The protein modeling methods SWISS-MODEL, Robetta, and AlphaFold2 were used, and the protein model was analyzed to obtain the reliable protein structure. The semi-rational design of mutant protein was carried out by molecular docking and homologous alignment. The key amino acid sites affecting the oxidation activity of CYP76AK1 were identified by molecular docking. The function of the obtained mutations was studied with yeast expression system, and the CYP76AK1 mutations with continuous oxidation function to 11-hydroxysugiol were obtained. Four key amino acid sites that affected the oxidation acti-vity were analyzed, and the reliability of three protein modeling methods was analyzed according to the mutation results. The effective protein modification sites of CYP76AK1 were reported for the first time in this study, which provides a catalytic element for different oxidation activities at C20 site for the study of the synthetic biology of tanshinones and lays a foundation for the analysis of the conti-nuous oxidation mechanism of P450-C20 modification.

Advances of development and application amino acid biosensors / 生物工程学报

Amino acids are the basic building blocks of protein that are very important to the nutrition and health of humans and animals, and widely used in feed, food, medicine and daily chemicals. At present, amino acids are mainly produced from renewable raw materials by microbial fermentation, forming one of the important pillar industries of biomanufacturing in China. Amino acid-producing strains are mostly developed through random mutagenesis- and metabolic engineering-enabled strain breeding combined with strain screening. One of the key limitations to further improvement of production level is the lack of efficient, rapid, and accurate strain screening methods. Therefore, the development of high-throughput screening methods for amino acid strains is very important for the mining of key functional elements and the creation and screening of hyper-producing strains. This paper reviews the design of amino acid biosensors and their applications in the high-throughput evolution and screening of functional elements and hyper-producing strains, and the dynamic regulation of metabolic pathways. The challenges of existing amino acid biosensors and strategies for biosensor optimization are discussed. Finally, the importance of developing biosensors for amino acid derivatives is prospected.

A Core Genome Multilocus Sequence Typing Scheme for Proteus mirabilis / 生物医学与环境科学（英文）

OBJECTIVE@#A core genome multilocus sequence typing (cgMLST) scheme to genotype and identify potential risk clonal groups (CGs) in Proteus mirabilis.@*METHODS@#In this work, we propose a publicly available cgMLST scheme for P. mirabilis using chewBBACA. In total 72 complete P. mirabilis genomes, representing the diversity of this species, were used to set up a cgMLST scheme targeting 1,842 genes, 635 unfinished (contig, chromosome, and scaffold) genomes were used for its validation.@*RESULTS@#We identified a total of 205 CGs from 695 P. mirabilis strains with regional distribution characteristics. Of these, 159 unique CGs were distributed in 16 countries. CG20 and CG3 carried large numbers of shared and unique antibiotic resistance genes. Nine virulence genes ( papC, papD, papE, papF, papG, papH, papI, papJ, and papK) related to the P fimbrial operon that cause severe urinary tract infections were only found in CG20. These CGs require attention due to potential risks.@*CONCLUSION@#This research innovatively performs high-resolution molecular typing of P. mirabilis using whole-genome sequencing technology combined with a bioinformatics pipeline (chewBBACA). We found that the CGs of P. mirabilis showed regional distribution differences. We expect that our research will contribute to the establishment of cgMLST for P. mirabilis.
