The software ArcGIS 10.8 was employed for spatial autocorrelation analysis, and SaTScan 10.1 was employed for spatio-temporal scanning to analyze the temporal and spatial clustering characteristics of influenza incidence in Yinzhou District.@*Results@#Totally 60 543 influenza cases were reported in Yinzhou District from 2017 to 2021, with an incidence of 0.76%. The incidence of influenza peaked in December 2019 (9.35%) and January 2020 (9.28%) during the period between 2017 and 2021. Spatial autocorrelation analysis showed that there was a positive spatial correlation of influenza incidence in Yinzhou District from 2018 to 2021 (all P<0.05), and a high clustering in 2019 and 2021. Zhonghe Street showed a low-high clustering from 2017 to 2020; Jiangshan Town showed a low-high clustering in 2017 and 2020, and a high-high clustering in 2019 and 2021; Shounan Street showed a high-high clustering from 2018 to 2020; Yunlong Street showed a high-high clustering in 2021. Spatio-temporal scanning analysis showed that the class Ⅰ clusters were located in the central region which centered in Dongqianhu Town, with aggregation time in August 2017, in the northwest region with aggregation time in December and January from 2018 to 2020, and in the west region with aggregation time in August 2021.@* Conclusion @#The incidence of influenza in Yinzhou District from 2017 to 2021 showed a spatio-temporal clustering in the northwestern region in winter and summer.
ABSTRACT
Objective@#To identify a pig model with bilateral external ear defects accompanied by aural atresia and investigate its application in plastic surgery.@*Methods@#Erhualian×Shaziling F2 pig inbreeding population was introduced, and examination of external ear morphology was conducted in all individuals. Temporal computed tomography scanning and mutational detection of HOXA1 gene were conducted in one affected and one normal individuals.@*Results@#In Erhualian×Shaziling F2 pig inbreeding population, there were 57 normal and 18 affected individuals among the 75 pigs. Affected subjects presented bilateral external ear defects accompanied by aural atresia; temporal computed tomography scanning showed bilateral aural atresia and dysplasiaof middle ear; and gene detection identified homozygous mutation of HOXA1 gene.@*Conclusions@#Pig model with HOXA1 gene homozygous mutation resembles human microtia at different levels. Our findings provide the theoretical basis for its application to study further pathological mechanism for human microtia.
ABSTRACT
La afasia progresiva primaria (APP) es un síndrome clínico neurodegenerativo caracterizado por compromiso progresivo del lenguaje, diagnosticado cuando completa tres criterios nucleares. Primero, debe existir compromiso del lenguaje, que interfiera con el uso o comprensión de las palabras. Segundo, el plan de trabajo diagnóstico debe demostrar que la enfermedad es neurodegenerativa, y además progresiva. Tercero, la afasia debe progresar relativamente aislada, sin afectación del comportamiento o de memoria episódica. El compromiso del lenguaje puede ser fluente o no fluente y puede o no interferir con la comprensión de las palabras. La memoria para hechos recientes está preservada, sin embargo los puntajes de memoria obtenidos en las pruebas mediadas verbalmente pueden ser anormales. Pueden presentarse cambios menores en personalidad o en la conducta, pero no llevan al paciente a la consulta médica y no limitan las actividades de vida diaria. Este patrón clínico es más conspicuo en los estadios iniciales de la enfermedad, y es consecuencia de la atrofia relativamente selectiva de los circuitos del lenguaje, usualmente localizado en el hemisferio izquierdo. Existen diferentes variantes clínicas de APP, cada una con un patrón característico de atrofia. Las enfermedades neuropatológicas subyacentes son heterogéneas y pueden incluir enfermedad de Alzheimer así como degeneración lobar fronto-temporal.
Primary progressive aphasia (PPA) is a neurodegenerative clinical syndrome characterized by progressive language impairment diagnosed when three core criteria are met. First, there should be a language impairment (i.e., aphasia) that interferes with the usage or comprehension of words. Second, the neurological work-up should determine that the disease is neurodegenerative, and therefore progressive. Third, the aphasia should arise in relative isolation, without equivalent deficits of comportment or episodic memory. The language impairment can be fluent or non fluent and may or may not interfere with word comprehension. Memory for recent events is preserved although memory scores obtained in verbally mediated tests may be abnormal. Minor changes in personality and behavior may be present but are not the leading factors that bring the patient to medical attention or that limit daily living activities. This distinctive clinical pattern is most conspicuous in the initial stages of the disease, and reflects a relatively selective atrophy of the language network, usually located in the left hemisphere. There are different clinical variants of PPA, each with a characteristic pattern of atrophy. The underlying neuropathological diseases are heterogeneous and can include AlzheimerÆs disease as well as frontotemporal lobar degeneration.

INTRODUCCIÓN: el dengue es una de las enfermedades víricas de transmisión vectorial más importante en las Américas, por causa, entre otros factores, del incremento de las poblaciones de Aedes aegypti. OBJETIVO: conocer el comportamiento espacial y temporal de Ae. aegypti en el municipio Cienfuegos durante 2006-2008. MÉTODOS: el estudio se realizó en el municipio Cienfuegos, ubicado al centro - sur de Cuba. Se hicieron colectas larvales y de adultos en todo el municipio durante 2006-2008, siguiendo la metodología establecida por el programa de erradicación del vector del dengue. RESULTADOS: la riqueza de especies de mosquitos encontrada fue de 12, Culex quinquefasciatus, Ochlerotatus taeniorhynchus, Gymnometopa mediovittata y Aedes aegypti resultaron las más abundantes. Los depósitos de mayor positividad a Ae. aegypti fueron los tanques bajos, los diversos y la larvitrampa; la mayor positividad se reportó durante agosto-noviembre. Las mayores cantidades de mosquitos adultos capturados ocurrieron en los meses de julio a octubre. De los 2 métodos, el que más adultos aportó fue la captura en reposo con 134 (96,41 por ciento), 30 (96,78 por ciento) y 27 (100 por ciento), respectivamente; con una diferencia altamente significativa, p< 0,0001. En la estratificación entomológica sugerida de las áreas en el municipio se deben de priorizar las áreas II y III como de riesgo alto, la I y la V como riesgo mediano y el resto de nivel bajo. CONCLUSIÓN: resulta de vital importancia mantener una alerta constante sobre Ae. aegypti, porque este mantiene su presencia todo el año en el universo completo del municipio Cienfuegos.
INTRODUCTION: dengue is one of the most important vector-borne diseases in Las Americas due, among other factors, to the increase of Aedes aegypti populations. OBJECTIVE: to ascertain the space and time behaviour of Ae. aegypti in Cienfuegos municipality from 2006 to 2008. METHODS: the study was conducted in Cienfuegos municipality located on the central south part of Cuba. Larvae and adult mosquitoes were collected throughout the municipality in the 2006-2008 period using the methodology of the national dengue vector eradication program. RESULTS: twelve mosquito species were found; Culex quinquefasciatus, Ochlerotatus taeniorhynchus, Gymnometopa mediovittata and Aedes aegypti were the most abundant. The containers showing the highest positivity to Ae. aegypti presence were water tanks on the ground, various reservoirs, and larvitraps; the highest positive indexes were reported in August through November. The highest amounts of adult mosquitoes were captured in July through October. Of the 2 methods, capture at rest was more effective in collecting more adult mosquitoes with 134 (96.41 percent), 30 (96.78 percent) and 27 (100 percent), respectively and highly significant difference, p< 0.0001. According to the entomological stratification of the areas in the municipality, the areas 2 and 3 must be classified as high risk, the areas 1 and 5 as mild risk and the rest of the areas as low risk areas. CONCLUSION: it is of vital importance to be permanently on the alert because Aedes aegypti is present throughout the year in the Cienfuegos municipality.
