Iniquidades interseccionais no atendimento obstétrico às mulheres negras de comunidade quilombola / Intersectional inequities in obstetric care for black women in quilombola community / Inequidades interseccionales en el servicio obstétrico a las mujeres negras de comunidad quilombola

Introdução:A conjuntura socioeconômica e cultural da mulher negra a coloca em tripla vulnerabilidade, que se explica pelo fato de que ela é vítima do racismo, do preconceito de classe e da discriminação de gênero, e essa interação de diferentes tipos de opressão é explicada pela teoria da interseccionalidade. Esse negligenciamento precariza-se ainda mais quando se reporta para a atenção àsaúde. Objetivo:Compreender como o contexto social da interseccionalidade de raça, classe e gênero refletem no atendimento obstétrico em Saúde Pública de mulheres negras residentes em comunidade quilombola. Metodologia:Trata-se de pesquisa qualitativa de caráter descritivo-exploratório, realizada com duas mulheres negras residentes em comunidade quilombola, localizada em município no interior do estado do Ceará. Como instrumento para coleta de dados, utilizou-se a entrevista semiestruturada, sendo os dados submetidos à análise do discurso. Resultados:Os sujeitos desta investigação conseguem, a partir de situações do quotidiano vivenciadas nos serviços de saúde públicos, identificar exemplos de racismo e/ou preconceito relacionados ao fato de serem mulheres negras e pobres. Assim, a vulnerabilidade interseccional (raça ­gênero ­classe social) implica em desigualdades no acesso aos serviços de saúde, o que se materializa em violência obstétrica, negligência em relação ao direito da mulher negra sobre o próprio corpo, além de negação da sua subjetividade, o que viola os pressupostos do Sistema Único de Saúde (SUS), particularmente os princípios da universalidade, equidade e integralidade da assistência. Conclusões:Constata-se, portanto, que as iniquidades quanto ao atendimento obstétrico, que afetam majoritariamente as mulheres negras e pobres, apresentam-se como problemática de gestão, denotando o déficit na efetivação de políticas públicas de saúde, ou a sua ausência. Há também a necessidade de que os profissionais de saúde, a partir de educação continuada, tenham um olhar mais holístico, a fim de produzir um atendimento equânime e integral (AU).

Introduction:Black women's socioeconomic and cultural conjuncture puts them into a three-fold vulnerability, which is explained by the fact that they are victims of racism, class prejudice and gender discrimination, and this interaction of different types of oppression is explained by the theory of intersectionality. Such negligence is even more precarious when it comes to healthcare. Objective:To understand how the social context of the intersectionality of race, class and gender reflects on the obstetric care in public healthcare provided to black women residing in quilombola communities. Methodology:This is a qualitative research work of a descriptive-exploratory nature, carried out with two black women residing in a quilombola community located in the a rural areain the state of Ceará. As a data collection instrument, we used semi-structured interviews, and the data was submitted to discourse analysis. Results:The subjects of this investigation can, from daily situations experienced in public healthcare services,identify examples of racism and/or prejudice related to the fact that they are poor black women. Therefore, intersectional vulnerability (race ­gender ­social class) leads to inequalities in the access to healthcare services, which materializes as obstetric violence, negligence to black women's right to their own bodies, as well as denial of their subjectivity, which violates the presuppositions of the Brazilian Unified Health System (SUS), especially the principles of universality, equity, and integrality of care. Conclusions:It is therefore verified that the inequities of obstetric care, which mostly affect poor black women, present themselves as a management problem, denoting the deficit in the application of public healthcare policies, or their absence. There is also a need for healthcare providers, through continued education, to have a more holistic view in order to provide more equanimous and integral healthcare (AU).

Esta negligencia se precariza mucho más cuando se trata de la atención médica. Objetivo:Comprender cómo el contexto social de la interseccionalidad de raza, clase y género se refleja en la atención obstétrica en la Salud Pública de mujeres negras que viven en una comunidad quilombola.

Así, la vulnerabilidad interseccional (raza ­género ­clase social) implica en desigualdades en el acceso a los servicios de salud, que se materializan en violencia obstétrica, negligencia en relación a los derechos de las mujeres negras sobre sus propios cuerpos, además de la negación de su subjetividad, que viola los supuestos del Sistema Único de Salud, en particular los principios de universalidad, equidad e integralidad de la atención. Conclusiones: Se puede observar que las inequidades en la atención obstétrica, que afectanmayormente a mujeres negras y pobres, se presentan como un problema de gestión, denotando el déficit en la implementación de políticas públicas de salud, o su ausencia. También es necesario que los profesionales de la salud, basados en la educación continua, tengan una visión más holística, para producir una atención equitativa e integral (AU).

Dental Loss in the Lower Socioeconomic Stratum of a Sample of the Chilean Population Born in the 19TH and 20TH Centuries / Pérdida Dental en el Estrato Socioeconómico Bajo de una Muestra de la Población Chilena Nacida en los Siglos XIX y XX

SUMMARY: Partial or total dental loss (edentulism) is associated with decreased quality of life. Chile has large socioeconomic gaps, which are also recognized in oral health, but it is not known how Edentulism has evolved throughout the country. The aim of this study was to determine the edentulism in people born during the 19th and 20th centuries in Chile, who died in the 20th century, and to compare it with current data from the Chilean Ministry of Health (MINSAL) to observe its evolution in the country. For this purpose, 60 3D models of skulls from the Subactual Osteological Collection of Santiago were analyzed (30 individuals per sex), in which the presence and absence of teeth in antemortem in the maxilla were analyzed. A high percentage of tooth loss was observed, with 65 % partial edentulism, a 30 % total edentulism, and only 5 % had complete dentition in this osteological collection. In addition, a significant decrease over time was found; in 2017, the percentage of complete dentition at the national level was 32.8 %. A higher frequency of edentulism was also found in females from the osteological collection, with a significant probability of twice as much edentulism as in males. However, this sex difference was smaller than those found in the current study. Our study is the first to compare edentulism in Chile in two different time periods, since, in addition to studying it in the 19th and 20th century, it is carried out with data from the present day and in line with previous research, reveals the importance of socioeconomic and sex variables for dental loss.

La pérdida parcial o total de dientes (edentulismo) se asocia a una disminución de la calidad de vida. Chile tiene grandes brechas socioeconómicas, que también se reconocen en la salud oral, pero se desconoce cómo ha evolucionado el edentulismo en el país. El objetivo de este estudio fue determinar el edentulismo en personas nacidas durante los siglos XIX y XX en Chile y fallecidas en el siglo XX, y compararlo con datos actuales del Ministerio de Salud de Chile (MINSAL) para observar su evolución en el país. Para ello, se analizaron 60 modelos 3D de cráneos de la Colección Osteológica Subactual de Santiago (30 individuos por sexo), en los que se analizó la presencia y ausencia de dientes en dentición antemortem en el maxilar. Se observó un alto porcentaje de pérdida dentaria, con un 65 % de edentulismo parcial y un 30 % de edentulismo total, y sólo un 5 % presentaba dentición completa en esta colección osteológica. Además, se encontró una disminución significativa a lo largo del tiempo; en 2017, la dentición completa a nivel país fue del 32,8 %. También se encontró una mayor frecuencia de edentulismo en las mujeres de la colección osteológica, con una probabilidad significativa del doble de edentulismo que en los hombres. Sin embargo, esta diferencia de sexo fue menor que la hallada en datos actuales. Este estudio es el primero que compara el edentulismo en Chile en dos épocas diferentes, ya que además de estudiarlo en los siglos XIX y XX, se realizó con datos de la actualidad y, en línea con investigaciones previas, revela la importancia de las variables socioeconómicas y de sexo en la pérdida dental.

Mortalidad infantil y condiciones de vida socioeconómicamente adversas: el caso de dos distritos poblacionales en Santiago de Cuba

Introducción: La mortalidad infantil es un fenómeno sanitario relacionado directamente con las condiciones de vida deletéreas, tanto del hogar del infante como de factores socioeconómicos e higiénico-sanitarios adversos. Objetivo: Caracterizar las desigualdades de la mortalidad infantil, según condiciones diferenciales de vida en dos distritos poblacionales de Santiago de Cuba. Métodos: Se llevó a cabo un estudio descriptivo, de tipo ecológico exploratorio, en el municipio Santiago de Cuba, en el trienio 1995-1997. Las unidades de análisis estuvieron constituidas por las áreas de salud enmarcadas en dos distritos poblacionales de la ciudad. Resultados: Se estratificaron ambos distritos poblacionales, según sus condiciones de vida, en asentamientos con condiciones de vida menos desfavorables y más desfavorables. Se estimó mayor mortalidad infantil en el asentamiento con condiciones de vida más desfavorables (8,7 fallecidos por 1000 nacidos vivos), donde predominaron como causas clínicas de muerte las asfixias, la anoxia e hipoxias y causas clínicas reducibles por buena atención en el parto. Conclusiones: Se identificó un perfil diferencial de mortalidad infantil, según las condiciones de vida, al interior de los asentamientos poblacionales de los distritos urbanos de Santiago de Cuba. Los riesgos distintivos de muerte infantil fueron a expensas del componente neonatal, en lo fundamental por causas clínicas reducibles por buena atención en el parto.

Introduction: Infant mortality is a health phenomenon directly related to the deleterious living conditions of both the infant's home and adverse socioeconomic and sanitary factors. Objective: To characterize inequalities in infant mortality according to differential living conditions in two populations districts of Santiago de Cuba. Methods: A descriptive, exploratory ecological study was carried out in the municipality of Santiago de Cuba in 1995-1997. The units of analysis were constituted by the areas framed in two populations districts of the city. Results: Bothe population districts were stratified, according to their living conditions, in settlements with less unfavorable and more unfavorable living conditions. Higher infant mortality was estimated in the settlement with more unfavorable living conditions (8.7 deaths per 1000 live births), where asphyxia, anoxia and hypoxia predominated as clinical causes of death and clinical causes reducible for good care at birth. Conclusions: A differential profile of infant mortality, according to living conditions, was identified within the population settlements of the urban districts of Santiago de Cuba. The distinctive risks of infant death were at the expense of the neonatal component, mainly for clinical causes reducible by good care at birth.

Protocolo BAMP: Reporte de Caso Clínico

El presente reporte tiene como objetivo presentar de manera secuencial y visual la protracción maxilar de un paciente clase III esqueletal, utilizando el protocolo BAMP. Una vez realizado el análisis clínico del caso se decidió realiza un tratamiento ortopédico a través del uso de miniplacas de titanio con elásticos intermaxilares de clase III siguiendo el protocolo BAMP, junto a un tratamiento ortodóncico dento alveolar con aparatología fija bimaxilar prescripción Roth 0.22" Mini sprint forestadent. Se observa el éxito del enfoque interceptivo utilizando el protocolo BAMP. Este enfoque logró reducir tanto el tiempo como la complejidad del tratamiento ortodóncico, y también disminuyó la necesidad de someterse a una cirugía ortognática en la edad adulta. El tratamiento BAMP, diseñado para ciertas edades y crecimiento, se demostró exitoso en un paciente de 12 años sin potencial de crecimiento. Las miniplacas como anclaje son efectivas para protracción maxilar en varios casos, aunque se necesita seguimiento y educación postquirúrgica. Se recomienda retirar las miniplacas cuando no sean necesarias, adaptando el protocolo a cada paciente. En resumen, el tratamiento con miniplacas es eficaz para corregir anomalías Clase III esqueléticas.

The present report aims to sequentially and visually present the maxillary protraction of a Class III skeletal patient using the BAMP protocol. After conducting a clinical analysis of the case, it was decided to perform orthopedic treatment using titanium miniplates with Class III intermaxillary elastics following the BAMP protocol, in conjunction with dentoalveolar orthodontic treatment using fixed bimaxillary appliances with Roth prescription 0.022" Mini Sprint Forestadent. The success of the interceptive approach using the BAMP protocol is observed. This approach managed to reduce both the time and complexity of orthodontic treatment and also decreased the need for orthognathic surgery in adulthood. The BAMP treatment, designed for specific ages and growth stages, proved successful in a 12-year-old patient without growth potential. Miniplates as anchorage are effective for maxillary protraction in various cases, although post-surgical follow-up and education are required. It is recommended to remove the miniplates when they are no longer necessary, adapting the protocol to each patient. In summary, miniplate treatment is effective in correcting Class III skeletal anomalies.

Cone-beam computed tomography study of root length of maxillary and mandibular anterior teeth and central incisor crown-root morphology in high-angle Class Ⅱ open bite patients / 口腔疾病防治

Objective@#This study aimed to explore the root length of maxillary and mandibular anterior teeth and central incisor crown-root morphology in patients with high-angle skeletal Class Ⅱ open bite, aiming to provide a reference for clinical treatment.@*. Methods@#This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. CBCT images of eighty-one untreated patients (40 anterior open bite patients and 41 normal overbite patients) with high-angle skeletal Class Ⅱ malocclusion were selected before treatment. Dolphin software was used to study the root length of maxillary and mandibular anterior teeth and central incisor crown-root morphology, and the differences between the two groups were analyzed.@*Results@#There was no statistical significance in the root length of maxillary lateral incisor and canine between the open bite group and the normal overbite group, significant differences were found in the root length of maxillary central incisor （11.12 ± 1.37） mm、mandibular central incisor（10.15 ± 1.09）mm, mandibular lateral incisor（11.27 ± 1.15）mm and mandibular canine（12.81 ± 1.48）mm between the open bite group and the normal overbite group（P<0.05）. On the other hand, the two groups were significantly different in crown-root morphology of the maxillary central incisor (1.10° ± 3.62° vs. 4.53° ± 2.30°, P<0.01) but not in the mandibular central incisor.@*Conclusion@#The root length of the maxillary central incisor, mandibular central incisor, mandibular lateral incisor, mandibular canine in high-angle Class Ⅱ open bite patients is shorter than that in high-angle Class Ⅱ normal overbite patients, and the long axis of the crown of the maxillary central incisor in high-angle Class Ⅱ open bite patients obviously deviates toward the labial side relative to the long axis of the root. The crown-root angle is smaller, which is beneficial to torque control or adduction movement of the anterior teeth in high-angle Class Ⅱ open bite patients.

Analysis of latent classes and predictive factors of health behavior among stroke patients / 中华行为医学与脑科学杂志

Objective:To explore the latent classes of health behavior and explore the predictive factors among stroke patients.Methods:A total of 1 250 participants were recruited using cluster random sampling in September 2022. The general information, the modified Rankin scale(mRS), stroke prevention knowledge questionnaire(SPKQ), health behavior scale for stroke patients (HBS-SP), and short form-health belief model scale (SF-HBMS) were administered in the cross-sectional survey. Mplus 8.3 software was used to conduct a latent class analysis (LCA) on the health behavior of stroke patients, and SPSS 27.0 software was used to carry out multinomial Logistic regression to analyze the predictive factors of different latent classes of health behavior of stroke patients.Results:The health behavior of stroke patients obtained three latent classes: low health behaviors-lack of health responsibility group (66.9%, n=794), moderate health behaviors-poor compliance group (11.9%, n=141), and good health behaviors-insufficient exercise group (21.2%, n=251). Compared with good health behaviors-insufficient exercise group, stroke patients with shorter duration education time ( B=-0.589, OR=0.555, P=0.036), hemorrhagic stroke ( B=0.082, OR=1.086, P<0.001), fewer comorbidities ( B=-0.022, OR=0.978, P=0.026), higher mRS score ( B=-0.046, OR=1.047, P=0.004), lower SPKQ score ( B=-0.055, OR=0.947, P=0.016), and lower SF-HBMS score ( B=-0.085, OR=0.919, P<0.001) were more likely to be included in moderate health behaviors-poor compliance group. However, stroke patients with shorter duration education time ( B=-0.026, OR=0.974, P=0.003), rural areas dwelling ( B=0.800, OR=2.225, P=0.004), fewer comorbidities ( B=-0.056, OR=0.945, P<0.001), lower SPKQ score ( B=-0.101, OR=0.904, P<0.001), and lower SF-HBMS score ( B=-0.071, OR=0.931, P<0.001) were more likely to be included in low health behaviors-lack of health responsibility group. Conclusion:The health behavior of stroke patients has three latent classes. A targeted intervention should be carried out according to the characteristics of different classes to improve their health behavior levels.

Relationship between severity of preoperative brain injury and postoperative delirium in elderly patients: a latent class analysis of markers of brain injury / 中华麻醉学杂志

Objective:To evaluate the relationship between the severity of preoperative brain injury and postoperative delirium (POD) in elderly patients using latent class analysis based on markers of brain injury.Methods:One hundred and thirty-one American Society of Anesthesiologists Physical Status classification Ⅰ-Ⅲ patients, aged 65-84 yr, with a body mass index of 18-28 kg/m 2, scheduled for elective unilateral total hip arthroplasty in our hospital, were selected. Cognitive function was assessed using the Mini-Mental State Examination before surgery. Arterial blood samples were collected before anesthesia to measure the plasma concentrations of brain-derived neurotrophic factor, inducible nitric oxide synthase, prostaglandin E2, central nervous system-specific protein (S100β), glial fibrillary acidic protein, neurofilament light chain, matrix metalloproteinase-9, fibroblast growth factor 23, complement 3, complement 3a, complement 5a and irisin using enzyme-linked immunosorbent assay. POD was evaluated using the Confusion Assessment Method within 3 days after operation, and the patients were divided into POD group and non-POD group. The patients were divided into different injury severity subtypes based on the levels of brain injury markers using latent class analysis, and logistic multivariate regression was used to analyze the independent risk factors for POD. Results:Compared with non-POD group, the concentrations of neurofilament light chain, glial fibrillary acidic protein, S100β and prostaglandin E2 were significantly different in POD group ( P<0.05). Using these four brain injury markers for latent class analysis, patients were divided into a high severity of brain injury group (91.51%) and a low severity of brain injury group (8.49%). The results of logistic multivariate regression analysis showed that subtypes of brain injury ( OR=8.31, 95% confidence interval [ CI] 1.77-38.90, P=0.007), age ( OR=1.14, 95% CI 1.03-1.24, P=0.007), and plasma irisin concentrations ( OR=0.99, 95% CI 0.98-0.99, P=0.027) were independent risk factors for POD.

Comparison of the virtual surgical planning position of maxilla and condyle with the postoperative real position in patients with mandibular protrusion / 北京大学学报(医学版)

Objective:To compare the difference between virtual surgical planning(VSP)position and postoperative real position of maxilla and condyle,and to explore the degree of intraoperative realization of VSP after orthognathic surgery.Methods:In this study,36 patients with mandibular protrusion de-formity from January 2022 to December 2022 were included.All the patients had been done bilateral sagittal split ramus osteotomy(SSRO)combined with Le Fort Ⅰ osteotomy under guidance of VSP.The VSP data(T0)and 1-week postoperative CT(T1)were collected,the 3D model of postoperative CT was established and segmented into upper and lower jaws in CCMF Plan software.At the same time,accor-ding to the morphology of palatal folds,the virtual design was registered with the postoperative model,and the unclear maxillary dentition in the postoperative model was replaced.Then the postoperative model was matched with VSP model by registration of upper skull anatomy that was not affected by the opera-tion.The three-dimensional reference plane and coordinate system were established.Selecting anatomical landmarks and their connections of condyle and maxilla for the measurement,we compared the coordinate changes of marker points in three directions,and the angle changes between the line connecting the marker points and the reference plane to analyze the positional deviation and the angle deviation of the postoperative condyle and maxilla compared to VSP.Results:The postoperative real position of the maxilla deviates from the VSP by nearly 1 mm in the horizontal and vertical directions,and the anteropos-terior deviation was about 1.5 mm.In addition,most patients had a certain degree of counterclockwise rotation of the maxilla after surgery.Most of the bilateral condyle moved forward,outward and downward(the average distance deviation was 0.15 mm,1.54 mm,2.19 mm,respectively),and rotated forward,outward and upward(the average degree deviation was 4.32°,1.02°,0.86°,respectively)compared with the VSP.Conclusion:VSP can be mostly achieved by assistance of 3D printed occlusal plates,but there are certain deviations in the postoperative real position of maxilla and condyle compared with VSP,which may be related to the rotation axis of the mandible in the VSP.It is necessary to use patient personalized condylar rotation axis for VSP,and apply condylar positioning device to further improve surgical accuracy.

Soft and hard tissue changes of hyperdivergent class Ⅱ patients before and after orthodontic extraction treatment / 北京大学学报(医学版)

Objective:To investigate the hard and soft tissue changing trend and contributing factors of skeletal class Ⅱ hyperdivergent patients before and after orthodontic camouflage treatment by analyzing the cephalogram and the three dimensional(3D)facial scan data.Methods:Eighteen skeletal class Ⅱhyperdivergent adult female patients who finished camouflage orthodontic treatment were selected.Skele-tal and dental measurements were carried out with the cephalometric analysis before and after the treat-ment.3D facial data before and after orthodontic treatment were acquired and the anatomical landmarks were set after the repositioning and superimposition process.Hard tissue measurement included 17 mea-surement indicators(sella-nasion-subspinale angle,sella-nasion-supramental angle,subspinale-nasion-supramental angle,facial angle,angle of convexity,Frankfort horizontal plane-mandibular plane angle(FH-MP),Y axis angle,sella-nasion plane-mandibular plane angle(MP-SN),pogonion-nasion-supra-mental distance,upper incisor-nasion-subspinale distance,upper incisor to sella-nasion,lower incisor-nasion-supramental distance,lower incisor-nasion-supramental angle,upper incisor to lower incisor,up-per incisor to sella-nasion,lower incisor-mandibular plane angle,and Z angle),and the changes before and after treatment were measured for 11 of them.Twenty soft tissue landmarks(left/right cheekbone,left/right chelion,left/right crista philtra,soft tissue gnathion,left/right gonion,glabella,labrale infe-rius,labrale superius,soft tissue menton,left/right mid-mandibular border,soft tissue pogonion,stomi-on superius,sublabial,subnasale,and supralabial)and 9 soft tissue indicators(lower lip height,facial convexity,lower vermilion height,mandibular contour,nasolabial angle,philtral length,philtral width,upper lip height,and upper vermilion height)were measured and recorded for treatment changes.Linear-regression analysis and correlation analysis were carried out for analyzing the relationship between hard and soft tissue changes before and after the treatment.Results:Significant differences were noticed for 18 out of the 20 cephalometric measurements and facial measurements before and after the treatment(P＜0.05),which mainly represented the sagittal retraction of lip area after the treatment.Significant vertical displacements were revealed for soft tissue menton after treatment[(1.88±2.61)mm,P＜0.05].Significant sagittal displacements were revealed for left/right cheilion[(-2.95±1.9)mm,(-2.90±1.92)mm],labrale inferius[(-4.94±1.95)mm],labrale superius[(-3.25±1.44)mm],sublabial[(-3.10±3.5)mm],and subnasale[(-1.23±1.06)mm]after treatment(P＜0.05).An average of 4.10°±2.57° increasement was noticed for Z angle after treatment.High correla-tion(r＞0.7)was noticed for the displacement of menton after treatment with FH-MP,with the rate of-0.183:1,and MP-SN,with the rate of-0.157:1.Moderate correlations(0.7≥r＞0.4)were no-ticed for the other measurements with correlations(P＜0.05).Conclusion:A certain extent of facial improvements could be achieved with orthodontic camouflage treatment for skeletal class Ⅱ hyperdiver-gent patients,which were mostly represented by the improvement of sagittal relationship of nose,lips,and chin.Certain correlations were noticed for the hard and soft tissue changes.

Chitosan oligosaccharides alleviates the formation of atherosclerotic plaque through up-regulating core-fucosylation of SRBI in mice / 基础医学与临床

Objective To explore the mechanism of chitosan oligosaccharides(COS)in reducing atherosclerotic plaque formation from the perspective of protein glycosylation modification.Methods Totally 40 ApoE-/-mice were randomly divided into control group and COS group.The control group was given a high-fat diet for 12 weeks,and COS group was given a high-fat diet plus COS(gavage per day,500 mg/kg)for 12 weeks.Serum lipid detection,HE staining and Oil red O staining were used to detect plaque formation.Lectin chip,liquid chromatography tan-dem-mass spectrometry and ELISA were used to detect potential changes of glycoprotein in serum.Cholesterol ester outflow and free cholesterol ester determination experiment were used to evaluate the effect of changes in scavenger receptor class B type Ⅰ(SRBI)protein glycosylation modification site on cholesterol effluence in macrophages.Results COS significantly reduced the level of TC and LDL-C(P＜0.05)in mice,but had no effect on the level of TG,HDL-C,ApoA1 and ApoB100.The intima thickness and plaque size of the aorta were significantly thinner and smaller(P＜0.05)in the COS group compared with the control group.The molecular weight of lens culinaris ag-glutinin(LCA)binding protein with the most obvious change is 80-90 ku,and SRBI was one of them.COS promo-ted the cholesterol outflow and inhibited the accumulation of free cholesterol ester in RAW264.7 cell(P＜0.05).Knockdown or glycosylation site mutation with SRBI inhibited cholesterol outflow caused by COS,and increased the accumulation of intracellular free cholesterol(P＜0.05).Conclusions COS promotes lipid efflux by increasing SRBI glycosylation and expression,thereby alleviating atherosclerotic plaque formation.

Latent Class Analysis and Influencing Factors of Cognitive Ability Level of Hospice Care Nursing Students / 昆明医科大学学报

Objective To explore the different latent class and characteristics of the cognitive ability level of undergraduate nursing students in hospice care based on the individual-centered perspective,and analyze its influencing factors to provide the reference for the formulation of targeted nursing education.Methods Nursing students in a medical university in Yunnan Province were selected from March 2023 to June 2023.The general data questionnaire and hospice care knowledge questionnaire were used to conduct a cross-sectional survey.SPSS and Mplus were used for the data analysis.Results Three latent class of hospice care cognitive ability were identified,which were named as hospice care high cognitive ability group,general cognitive ability group,and low cognitive ability group,accounting for 28.74%,57.29%,and 13.97%,respectively;Nursing students'gender,nationality,place of residence,earning and practice experience of hospice care(whether they had the contact with end-stage cancer patients,whether they had received the hospice care related training),and whether they were willing to engage in the hospice care related work were the influencing factors of different potential categories of cognitive ability of hospice care among nursing students(P<0.05).Conclusion There are three latent class of hospice care cognitive ability of nursing students.Male minority nursing students who have not been exposed to end-stage cancer patients and have not received the hospice care-related training,are unwilling to engage in the hospice care-related work.Male ethnic minority nursing students residing in rural areas have the weaker cognitive levels of hospice care.Scholars in the future can formulate targeted training strategies according to different latent class of hospice care cognitive ability to improve nursing students'hospice care cognitive ability and reserve talents for hospice care teams.

Comparison of the effects of early Skeletal Class Ⅲ facemask therapy between dental and skeletal anchora-ges / 实用口腔医学杂志

Objective:To compare the effects of treatment with Hybrid-Hyrax-Facemask(FM)versus miniscrews in the anterior pal-ate combined with Hybrid-Hyrax-Facemask(MSI/FM)for patients with early Class Ⅲ malocclusion and maxillary deficiency.Methods:18 patients aged with early Class Ⅲ malocclusion and maxillary deficiency were randomly divided into 2 groups(n=9)and treated with FM and MSI/FM respectively.Alternating rapid maxillary expansion and constriction(Alt-RAMEC)protocol combined with a maxillary protraction force of 3.92 N was applied on each side of all patients from elastics connected to the facemask in a down-ward and forward direction of 30° to the occlusal plane.Iortho cephalometric software was used to analyze the data of lateral cephalo-grams of the patients before(T0)and after(T1)treatment.Results:Improvement was verified in the facial profile and occlusion of all patients.In MSI/FM group the average treatment time was shorter.There were significant differences(P＜0.05)between T0 and T1 in the following measurements in FM group:SNA,ANB,Co-A,Co-Gn,Wits,S-Go,Na-Me,MP,U1-SN,UADH,LADH,Overjet,UL-EP increased,U1-L1 decreased.There were significant differences(P＜0.05)between T0 and T1 in the following measurements in the MSI/FM group:SNA,ANB,Co-A,Wits,Na-Me,MP,Y-axis,U1-SN,Overjet,UL-EP increased,SNB,Co-Gn-Co-A,S-Go/N-Me,U1-L1,L1-MP decreased.Conclusion:Both FM and MSI/FM combined with Alt-RAMEC protocol and a maxillary protraction force are effective in the treatment for Class Ⅲ patients with maxillary deficiency.MSI/FM may produce more significant bone effect and re-duce dental compensation,promote more forward growth of midface and more improvement in the growth direction of mandible and re-duce compensatory lip inclination of anterior teeth in shorter treatment time.

CBCT study of the maturation of the midpalatal suture fusion ratio in different vertical skeletal patterns of class Ⅰ malocclusion adults / 实用口腔医学杂志

Objective:To compare the variability of midpalatal suture maturation ratio of skeletal class Ⅰ malocclusion adults between genders,among positions and vertical skeletal patterns.Methods:173 skeletal class Ⅰ malocclusion adult patients were included and divided into 6 groups according to GoGn-SN Angle and gender:dolichofacial group(male 22,female 24)with GoGn-SN＞37.7°,me-sofacial Group(male 30,female 33)with 27.2°≤GoGn-SN≤37.7° and brachyfacial group(male 33,female 31)with GoGn-SN＜27.2°.The midpalatal suture maturation ratio in the corresponding area of anterior,medial and posterior region were measured and calculated by Mimics 21.0 software,the overlap of the anterior nasopalatine canal with the measurement site was recorded.Results:In the comparison of different genders,there was a statistically significant difference between males and females in the brachyfacial an-terior region(P＜0.001).In the comparison of different positions,except the females among the anterior,middle and posterior regions in brachyfacial group(P＞0.05),there were statistical differences in the fusion degree of the other parts of the palate suture(P＜0.05),and it gradually decreased from the posterior region to the anterior region.In the comparison of different vertical skeletal pat-terns,there was no statistical difference except the difference between the mesofacial and brachyfacial and dolichofacial groups in the middle area of males(P＞0.05),and the difference was significant among brachyfacial,dolichofacial and mesofacia groups in the ante-rior area of females(P＜0.05).Rates of anterior nasopalatine duct influence measurements were statistically significant in the compari-son between dolichofacial and brachyfacial males,and between brachyfacial males and brachyfacial females(P＜0.05),the remainder was not statistically significant(P＞0.05).Conclusion:In adult patients,the palatal suture is not completely fused,and palatal mi-croimplant anchorage should be avoided in the midpalatal suture.
