Medical faculty's perception of students' mental health: a qualitative survey study / Percepción de los profesores de medicina sobre la salud mental de los estudiantes: un estudio cualitativo / Percepção dos docentes de medicina sobre a saúde mental dos estudantes: um estudo qualitativo

This study sought to explore the perspective of medical faculty on the mental health of their students. This qualitative study based on a focus group is part of a longitudinal research that studied the mental health of Brazilian students. One group was conducted with faculty employed at a medical school. Topics discussed covered the concept of mental health and medical education. Six professors participated in one group. The mental health of medical students is a construct that encompasses emotional aspects, ability to solve problems and multiple facets of a human being, according to the participants. Artistic practices, moments of socialization and leisure were perceived as stimulating students' good mental health. Excessive demands generate competitiveness and the teacher's expectation of the student's good performance based on their own experience can harm the student's mental health. Participants also highlighted that a pedagogical reformulation that makes sense for the student's learning process is necessary to update traditional curricula. Medical students' mental health is influenced by experiences and exchanges during the medical school, mainly between professor and student, understood as necessary and inherent to the process of becoming physician. The findings of this study show the need for curriculum changes in the medical education process and updating teacher training for good practices that reinforce good mental health.

Un grupo se llevó a cabo con profesores empleados en una escuela de medicina. Los temas tratados abarcaron el concepto de salud mental y educación médica. Seis docentes participaron en un grupo. La salud mental de los estudiantes de medicina es un constructo que abarca aspectos emocionales, capacidad de resolución de problemas y múltiples facetas del ser humano, según los participantes. Las prácticas artísticas, los momentos de socialización y el ocio fueron percibidos como estimulantes de la buena salud mental de los estudiantes. Las exigencias excesivas generan competitividad y la expectativa del docente sobre el buen desempeño del estudiante basándose en su propia experiencia puede perjudicar la salud mental del estudiante. Los participantes también resaltaron que es necesaria una reformulación pedagógica que tenga sentido para el proceso de aprendizaje del estudiante para actualizar los currículos tradicionales. La salud mental de los estudiantes de medicina está influenciada por las experiencias y los intercambios durante la carrera de medicina, principalmente entre profesor y estudiante, entendidos como necesarios e inherentes al proceso de convertirse en médico. Los hallazgos de este estudio muestran la necesidad de cambios curriculares en el proceso de formación médica y de actualización de la formación docente hacia buenas prácticas que refuercen la buena salud mental.

Contribuições dos grupos operativos da atenção básica a partir da visão dos usuários / Aportes de los grupos operativos de atención primaria desde la visión de los usuarios / Contributions of primary care operating groups from user perception

Os grupos em saúde nascem para fomentar práticas coletivas de saúde, tendo se expandido para a atenção básica, encontrando ressonância na promoção da saúde e da qualidade de vida. Baseados nas teorias de Pichon-Rivière e de Yalom e Leszcz, esses grupos são capazes de contribuir para mudanças significativas na qualidade de vida de seus usuários participantes. Este artigo tem como objetivo analisar as contribuições dos grupos operativos da atenção primária à saúde a partir da visão de seus usuários e compreender a operacionalização desses grupos. Trata-se de pesquisa descritiva e analítica de caráter qualitativo, realizada em quatro grupos operativos em saúde da atenção básica de um município do Rio Grande do Norte, no interior do semiárido nordeste brasileiro. Os dados foram coletados por questionário socioeconômico e grupos focais entre março e agosto de 2023, sendo utilizada estatística descritiva para os questionários e análise temática de conteúdo para os grupos focais. Os questionários revelaram um predomínio de participantes do sexo feminino, com faixa etária acima dos 60 anos e situação socioeconômica de baixa renda. A análise de conteúdo demonstrou a efetividade dos grupos em produzir vetores grupais e fatores terapêuticos, além de seu potencial, como campo para a educação popular em saúde, em fomentar as redes sociais, o apoio, o acolhimento e o bem-estar biopsicossocial. Os grupos em saúde são estratégias eficazes na promoção da saúde e na qualidade de vida. Entretanto, ressalta-se a necessidade de pesquisas que avaliem a eficácia global dos grupos nos processos de morbimortalidade.

Health care groups were created to promote collective health practices and were expanded into Primary Care, helping to promote health and quality of life. Based on the theories of Pichon-Rivière and Yalom and Lezscz, these groups can contribute to significant changes in the quality of life of their participating users. Thus, this article analyzes the contributions of Primary Health Care operating groups from users' perspective and understands their operationalization. A descriptive analytical qualitative research was conducted with four health operating groups in Primary Care from a municipality in Rio Grande do Norte, in the semi-arid northeastern Brazil. Data were collected by means of a socioeconomic questionnaire and focus groups between March and August 2023, and investigated using descriptive statistics (questionnaires) and thematic content analysis (focus groups). The questionnaires revealed a predominance of female participants over 60 years old and with low-income socioeconomic status. Content analysis showed the groups' effectiveness in producing group vectors and therapeutic factors, as well as their potential as a field for popular health education in fostering social networks, support, user embracement, and biopsychosocial well-being. Health groups are effective strategies for promoting health and quality of life, future research should evaluate their global effectiveness in morbidity and mortality.

OBJETIVO: Compreender experiência de grupo orientado pela Abordagem Centrada na Pessoa (ACP) com mulheres que vivenciam o ciclo gravídico puerperal, no contexto do Sistema Único de Saúde (SUS). MÉTODO: Pesquisa qualitativa, de inspiração fenomenológica, e utilização do referencial da ACP como norteador do estudo. As informações foram coletadas por meio de grupo, em quatro encontros presenciais nos meses de maio e junho de 2022, utilizando-se dos instrumentos Versão de Sentido (VS's) e Entrevista Fenomenológica (EF), sendo as informações organizadas em Eixos de Sentido e compreendidas a partir das premissas da ACP em diálogo com estudos vinculados às temáticas emergidas. RESULTADOS E DISCUSSÃO: Os Eixos elaborados a partir das VS's evidenciaram aspectos e tendências típicas do desenvolvimento de grupo fundamentado pela ACP; descreveram o grupo como espaço de acolhimento e liberdade experiencial, no qual se facilitou a expressão de vivências significativas relacionadas à gestação, parto e puerpério; apresentaram, ainda, o sentido de que a experiência grupal constituiu-se como promotora de trocas e apoio mútuo, de desenvolvimento e aprendizagens significativas. Os Eixos formulados com base na EF revelaram que as mulheres compreenderam a participação no grupo como uma experiência positiva, que propiciou cuidado aos aspectos emocionais, impulsionando autoconhecimento e desenvolvimento; e facilitadora de mudanças construtivas na vivência da maternidade. CONCLUSÃO: O estudo demonstrou a viabilidade de grupo centrado na assistência integral à saúde da mulher no período gravídico puerperal, e as convergências entre os princípios da ACP e os que orientam a prática na assistência do SUS.

OBJECTIVE: Understanding the group guided by the Person-Centered Approach (PCA) with women who experience the pregnancypuerperal cycle, in the Sistema Único de Saúde ­ SUS (Brazilian National Health System) context. METHOD: Qualitative research of phenomenological inspiration using the PCA framework as a guide for the study. Information was collected through groups, in four face-to-face meetings between May and June 2022, using the Sense's Version (SV's) and Phenomenological Interview (PI), with the information organized in Sense Axes and understood from the premises of the PCA in dialogue with studies linked to emerging themes. RESULTS AND DISCUSSION: The Axes created from the SV's showed aspects and tendencies which are typical of the development of a group based on the PCA; described the group as a welcoming space and experiential freedom, in which the expression of significant experiences related to pregnancy, childbirth and puerperium was facilitated; they also presented, the sense that the group experience was constituted as a promoter of exchanges and mutual support, of development and significant learning. The Axes formulated based on the PI, revealed that the women understood participation in the group as a positive experience, which provided care for emotional aspects, boosting self-knowledge and development; and a facilitator of constructive changes in the experience of motherhood. CONCLUSION: The study demonstrated the viability of a group centered on comprehensive care for women's health in the pregnancy-puerperal period between the PCA principles and those that guide the SUS care practice.

Incidence of Muscular Strength, Anthropometry, and Asymmetry in the General Index of Autonomy in Older Chilean Women / Incidencia de la Fuerza Muscular, Antropometría y Asimetría en el Índice General de Autonomía en Mujeres Mayores Chilenas

SUMMARY: Frailty affects the functional autonomy (FA) of older adults and could manifest itself in muscle imbalances in the limbs, resulting in a disparity in size and strength between them. In Chile, information on the relationship between muscle strength (MS) levels and FA asymmetries in older women is limited. This study related the levels of MS, anthropometric parameters, and asymmetries of the lower and upper limbs, with the FA of a group of older Chilean women. The study included 39 women who participated, and their FA was evaluated using the GDLAM index (IG). Based on the score obtained in the IG, they were classified by percentiles as Group 1 with favorable FA (P ≤ 50) and Group 2 with low FA (P > 50). Anthropometric parameters were BMI, fat percentage, bone mass, circumferences (arm, thigh, calf), diameters (humerus, femur) and upper/lower limb strength was evaluated to determine asymmetries. The differences between the covariates of both groups were evaluated using the student's t test and the Mann-Whitney test for independent samples. G1 presented less asymmetry (p > 0.05) in the lower limbs and greater calf circumference than G2 (p < 0.05). G1 presented greater bilateral strength (dominant and non-dominant limb) compared to G2 (p < 0.05). The covariates of age, anthropometry, MS, and lower/upper limb asymmetries influence FA in older women.

La fragilidad afecta la autonomía funcional (AF) de las personas mayores y podría manifestarse en desequilibrios musculares en los miembros, dando lugar a una disparidad de tamaño y fuerza entre ellos. En Chile, la información que relaciona los niveles de fuerza muscular (FM) y las asimetrías con la AF en mujeres mayores es limitada. Este estudio relacionó los niveles de FM, parámetros antropométricos y asimetrías de los miembros inferiores y superiores, con la AF de un grupo de mujeres mayores chilenas. Participaron 39 mujeres, cuya AF se evaluó mediante el índice GDLAM (IG). En función de la puntuación obtenida en el IG, se clasificaron por percentiles en Grupo 1 con AF favorable (P ≤ 50) y Grupo 2 con AF baja (P > 50). Los parámetros antropométricos fueron IMC, porcentaje de grasa, masa ósea, circunferencias (brazo, muslo, pantorrilla), diámetros (húmero, fémur) y se evaluó la fuerza de los miembros superiores/ inferiores para determinar asimetrías. Las diferencias entre las covariables de ambos grupos se evaluaron mediante la prueba t de student y la prueba de Mann-Whitney para muestras independientes. G1 presentó menor asimetría (p > 0,05) en los miembros inferiores y mayor perímetro de pantorrilla que G2 (p < 0,05). G1 presentó mayor fuerza bilateral (miembro dominante y no dominante) en comparación con G2 (p < 0,05). Las covariables de antropometría, FM y asimetrías de extremidades inferiores/superiores influyen en la AF en mujeres mayores.

Tamizaje al nacimiento del grupo sanguíneo ABO/RhD y la prueba directa de la antiglobulina de Coombs. Experiencia de una sola institución / Neonatal screening of ABO/RhD blood group and direct antiglobulin Coombs test. Experience of a single institution

Resumen Introducción: La determinación del grupo sanguíneo ABO/RhD y la prueba directa de Coombs (PDC) al nacimiento son una práctica recomendada, pero existe variabilidad en su implementación universal. Se presentan los resultados de la determinación al nacimiento del grupo ABO/RhD y la PDC en una cohorte institucional. Métodos: Se incluyeron los recién nacidos entre 2017 y 2020 en un hospital de atención a embarazos de alto riesgo. Se determinó el grupo ABO/RhD y se realizó la PDC en muestras de cordón umbilical o en las primeras 24 horas de vida. Se registraron las variables demográficas, maternas y neonatales. Se estimó la asociación entre las variables mediante la razón de probabilidad (OR). Resultados: Se incluyeron 8721 binomios. La PDC fue positiva en 239 recién nacidos (2.7%), siendo las variables asociadas a la PDC positiva la edad materna > 40 años (OR: 1.5;IC95%: 1.0-2.3), el nacimiento por vía cesárea (1.4; 1.1-2.0), la madre del grupo O (6.4; 3.8-11.8), la prematuridad (3.6; 2.6-5.0); el peso al nacer < 2500 g (2.1; 1.6-2.8); el neonato del grupo A (15.7; 10.7-23.1) o del grupo B (17.6; 11.4-27.2), la hemoglobina al nacer < 13.5 g/dl (4.5; 2.8-7.1) y la reticulocitosis > 9% (1.9; 1.2 a 3.1). Discusión: La frecuencia de PDC positiva neonatal es del 2.7%, con asociación significativa la incompatibilidad materna/neonatal al grupo ABO y RhD, con impacto significativo en diversas variables neonatales. Estos resultados apoyan la política de implementación universal al nacimiento de la determinación de ABO/RhD y PDC.

Abstract Background: Evaluating the ABO/RhD blood group and the direct antiglobulin Coombs test (DAT) at birth is recommended good practice, but there is variability in its universal implementation. This study aims to show the comparative results in various variables of clinical impact during the hospital stay of neonates with positive DAT compared with those with negative DAT, based on the systematic detection of the ABO/RhD group and DAT at birth. Methods: Newborns between 2017 and 2020 in a high-risk pregnancy care hospital were included. The ABO/RhD and DAT group was determined in umbilical cord samples or the first 24 hours of life. Demographic, maternal, and neonatal variables were recorded. The association between the variables was estimated using the odds ratio (OR). Results: 8721 pairs were included. The DAT was positive in 239 newborns (2.7%), with the variables associated with positive PDC being maternal age > 40 years (OR: 1.5; 95% CI: 1.0 to 2.3), birth by cesarean section (1.4; 1.1-2.0), mother group O (6.4; 3.8-11.8), prematurity (3.6; 2.6-5.0), birth weight < 2500 g (2.1; 1.6-2.8), newborn group A (15.7; 10.7-23.1) and group B (17.6; 11.4-27.2), hemoglobin at birth < 13.5 g/dl (4.5; 2.8-7.1) and reticulocytosis > 9% (1.9; 1.2 to 3.1). Discussion: The frequency of neonatal positive PDC was 2.7%, with a significant association with maternal/neonatal incompatibility to the ABO and RhD group, with a substantial impact on various neonatal variables. These results support the policy of universal implementation at the birth of the ABO/RhD and DAT determination.

Importancia de las determinaciones inmunohematológicas en el control prenatal de gestantes con grupo sanguíneo RhD negativo

La guía para la atención prenatal es el marco regulatorio de las normas de obstetricia para el control y cuidado de las gestantes, con énfasis en aquellas que poseen el grupo sanguíneo RhD negativo. La aloinmunización por anti-D es la causa más frecuente y grave de la enfermedad hemolítica del recién nacido. Para un diagnóstico temprano de la embarazada con dicho grupo sanguíneo, resulta necesario determinar los anticuerpos antieritrocitarios involucrados. En la presente comunicación se resalta la función del laboratorio de inmunohematología en el seguimiento de la gestante con grupo de sangre RhD negativo.

The guide for prenatal care is the regulatory mark of obstetrics norms for the control and care of pregnant women, with emphasis on those who have the RhD negative blood group. Alloimmunization by anti-D is the most frequent and serious cause of hemolytic disease of the newborn. For an early diagnosis of the pregnant woman with said blood group, it is necessary to determine the red blood cell antibodies involved. This communication highlights the role of the immunohematology laboratory in the follow-up of pregnant woman with RhD negative blood type.

Nicho trófico y bioclimático de dos especies andinas cercanamente emparentadas de Liolaemus (Squamata, Liolaemidae) en el sur del Perú / Trophic and bioclimatic niche of two closely related Andean species of Liolaemus (Squamata, Liolaemidae) in southern Peru

Resumen En el presente estudio, los nichos trófico y bioclimático de Liolaemus annectens y L. etheridgei son evaluados. Ambas especies se distribuyen en la región andina del sur del Perú. La comparación interespecífica del nicho trófico reveló a Lygaeidae (Hemiptera) como presa fundamental de L. etheridgei, mientras que las presas fundamentales en la dieta de L. annectens fueron larvas de Lepidoptera, Araneae, Curculionidae (Coleoptera) y Lygaeidae. Asimismo, se observó un importante consumo de material vegetal en ambas especies, por lo que pueden considerarse omnívoras. Ambas especies presentaron una baja amplitud de nicho trófico, con una tendencia especialista de consumo de presas, y un bajo solapamiento de nicho trófico. En cuanto al nicho Grinnelliano, la evaluación y comparación de modelos de nichos ecológicos, permitieron identificar las áreas de mayor idoneidad para la sobrevivencia de estas especies. Estas se encuentran en áreas de Arequipa, Moquegua y Tacna para L. etheridgei y en Arequipa, Puno, y Cusco para L. annectens. Ambas especies mostraron una baja superposición de nicho ecológico, rechazando la hipótesis de que ocupan nichos idénticos.

Abstract In the present study, the trophic and bioclimatic niches of Liolaemus annectens and L. etheridgei are evaluated. Both species are distributed in the Andean region of southern Peru. Interspecific comparison of the trophic niche revealed Lygaeidae (Hemiptera) as a fundamental prey for L. etheridgei, while the fundamental preys in the diet of L. annectens were Lepidoptera larvae, Araneae, Curculionidae (Coleoptera), and Lygaeidae. Additionally, a significant consumption of plant material was observed in both species, indicating an omnivorous diet. Both species exhibited a narrow trophic niche breadth, with a specialist tendency in prey consumption and low trophic niche overlap. Regarding the Grinnellian niche, evaluation and comparison of ecological niche models allowed the identification of areas of highest suitability for the survival of these species. These include some areas in Arequipa, Moquegua and Tacna for L. etheridgei, and some areas in Arequipa, Puno and Cusco for L. annectens. Both species showed low ecological niche overlap, rejecting the hypothesis of identical niches.

Improvement effects of glycyrrhizin on Helicobacter pylori-associated gastritis in rats and its mechanism / 中国药房

OBJECTIVE To investigate the improvement effects of glycyrrhizin （GL） on Helicobacter pylori （HP）-associated gastritis in rats and its mechanism. METHODS HP-associated gastritis rat model was induced by inoculating with 1×109 cfu/mL HP. The model rats were randomly divided into model group， positive control group （HP standard quadruple group）， GL low-dose， medium-dose and high-dose groups （5， 20， 50 mg/kg）， with 12 rats in each group. Another 12 healthy rats were selected as normal control group. Except the normal control group and model group were given constant volume of normal saline intragastrically， the other groups were given corresponding drugs intragastrically， once a day， for 30 consecutive days. After administration， rats received 13C urea breath test， and delta-over-baseline （DOB） was recorded； the pathological and cellular morphological changes of gastric mucosa in rats were observed， and pathological scoring was performed； the levels of interleukin-8 （IL-8）， IL-1β， tumor necrosis factor-α （TNF-α）， reactive oxygen species （ROS） and malondialdehyde （MDA） were detected in gastric mucosa of rats； mRNA expressions of high mobility group box-1 protein （HMGB1） and nuclear factor-κ-B （NF-κB）， relative expressions of nitric oxide synthases （iNOS） and HMGB1， the phosphorylation level of NF- κBp65 were also detected in rats. RESULTS Compared with normal control group， the DOB value， histopathological score of gastric mucosa， the levels of IL-8， IL-1β， TNF-α， ROS and MDA， relative expressions of HMGB1 and NF- κB mRNA， relative expressions of iNOS and HMGB1 protein and the phosphorylation level of NF-κB p65 were all increased significantly in model group （P＜0.05）； the epithelial cells of gastric mucosa in rats were incomplete in structure and decreased in the number， with an increase in cell fragments and vacuoles， and significant cell pyknosis. Compared with model group， the changes of the above indexes in GL groups and positive control group were significantly reversed （P＜0.05）； the changes in the above indicators in the GL high-dose group were more significant than GL low-dose and medium-dose groups （P＜0.05）； the pathological changes of gastric mucosal cells in rats had all improved. CONCLUSIONS GL may inhibit inflammation and oxidative stress by inhibiting the activation of HMGB1/NF-κB pathway， thus relieving HP-induced gastric mucosal injury.

Social media content analysis of public and private Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency facebook groups

Background@#As social media continue to grow as popular and convenient tools for acquiring and disseminating health information, the need to investigate its utilization by laypersons encountering common medical issues becomes increasingly essential. @*Objectives@#This study aimed to analyze the content posted in Facebook groups for Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency and how these engage the members of the group. @*Methods@#This study employed an inductive content analysis of user-posted content in both public and private Facebook groups catering specifically to G6PD deficiency. The G6PD Facebook groups with 10 or more posts within the past 12 months were selected for this study. Data were harvested from posts and comments using ExportComment. @*Results@#A total of 46 G6PD-related Facebook groups were identified. Of which, 19 were public and 27 were private groups, with an average membership of 5000-6000 accounts. After eligibility based on criteria and authorization for private groups, 3 public and 3 private groups were included, with the majority of these groups focused on sharing information. Five main themes of posted content were identified: diagnosis, management, beliefs, psychosocial factors, and medical requirements. “Diagnosis”-related posts referred to conversations about the causes and symptoms of G6PD, “management” referred to medication or diet, “beliefs” involved traditional or lay perceptions, “psychosocial factors” referred to posts that disclosed how psychosocial factors influenced G6PD deficiency practices, and “medical requirements” referred to documentation regarding the condition. The bulk of these posts used three strategies for communication: information-requesting, self-disclosure, and promotion of products/services. Information requests were the most common. @*Conclusion@#The results of the study showed opportunities and challenges in health education on G6PD, especially in evaluating the credibility and accuracy of the information given and received. Looking at the content and manner of communicating information noted, the newborn screening program may improve its advocacy and education campaign, and may develop targeted educational materials and effective dissemination strategies that could clarify, explain, or refute information and beliefs mostly shared on these platforms.

Objective To study the effect of high mobility group box B1(HMGB1)gene knockout on alleviating a-cute lung injury and inhibiting toll-like receptor 4(TLR4)/nuclear factor-KB(NF-κB)pathway of sepsis mice.Methods Wild-type(WT)mice were divided into WT-Sham group and WT-model group,and HMGB1 knockout(KO)mice were divided into KO-sham group and KO-model group.Sepsis ALI model was established by cecal ligation and perforation in WT-model group and KO-model group.Sham operation was performed in WT-Sham group and KO-Sham group.24 h after modeling,the partial pressure of arterial oxygen(PaO2)was detected,oxy-genation index(OI)was calculated,pathological changes of lung tissue were detected and lung injury score was calculated,the concentrations of tumor necrosis factor-α(TNF-α),interleukin-1 β(IL-1 β),interleukin-6(IL-6),reactive oxygen species(ROS),malondialdehyde(MDA),superoxide dismutase(SOD),in serum and lung tissues and the expression of HMGB1,TLR4 and nuclear NF-κB in lung tissues were detected.Results The PaO2,OI and the concentration of SOD in serum and lung tissue of WT-model group were lower than those of WT-Sham group,the lung injury scores,the concentrations of TNF-α,IL-1 β,IL-6,ROS and MDA in serum and lung tissue,and the expression levels of HMGB1,TLR4 and nuclear NF-κB in lung tissue were higher than those in WT-Sham group(P＜0.05).HMGB1 was not expressed in lung tissue of KO-model group,and the concentrations of PaO2,OI and the concentration of SOD in serum and lung tissue of KO-model group were higher than those of WT-model group,the lung injury scores,the concentrations of TNF-α,IL-1β,IL-6,ROS and MDA in serum and lung tissue,and the expression levels of TLR4 and nuclear NF-κB in lung tissue were lower than those of the WT-model group(P＜0.05).Conclusion HMGB1 gene knockout alleviates acute lung injury of sepsis mice,the re-lated molecular mechanism may be the inhibition of TLR4/NF-κB pathway mediated inflammation and oxidative stress.

Molecular biology analysis of 2 rare RhD variant individuals with RHD*DEL37 / 北京大学学报(医学版)

The Rh blood grouping system is a critical standardized test in transfusion medicine,espe-cially for the cases related to haemolytic transfusion reactions and neonatal haemolytic disease caused by clinical RhD blood group incompatibility.In the present case report,we presented two cases with the un-common RHD gene variation RHD*DEL37.The blood samples of the two subjects were mistakenly iden-tified as RhD-negative through conventional serological testing.Firstly,both blood samples were tested negative for the RhD antigen using traditional tube test and gel microcolumn methods.The phenotyping of RhCE were identified as ccEe and ccee for each sample,respectively.Secondly,genetic analysis was performed using polymerase chain reaction-sequence specific prime(PCR-SSP)which revealed that nei-ther sample belonging to the several common RHD gene variants which was found in Asia.Moreover,they turned out to be positive for the RHD haplotype,which indicated that exons 1-10 on one of the RHD al-leles were entirely absent.In addition,a T＞C mutation was observed at bases 1154-31 in intron 8 of the other allele,which was located at the intron 8 breakpoint.This result was obtained after further Sanger sequencing of exons 1-10 of the RHD gene.The mutant allele was designated as RHD*DEL37 by the International Society of Blood Transfusion(ISBT)and was identified as D-elute(Del)by phenotype ana-lysis.Both samples were genotyped as RHD*DEL37 and showed positive results.In summary,the true genotype of the two blood samples,of which the screening results only using serological testing method was negative,were RHD*DEL37/RHD-(RHD*01N.01).Notably,this kind of genotype was reported for the first time in Chinese population.Moreover,the two individuals did not have ties of consanguinity,indicating that some of the Chinese individuals could be carriers of the genetic mutation.Therefore,it might be necessary to further confirm the frequency of this mutation in the Chinese population and the possibility of homozygosity for this mutation.This report identifies infrequent RHD gene mutation samples by coupling molecular biology and serological methods to prevent misclassification of blood groups.Com-bining serological and molecular biology test results to determine blood group is critical in protecting pa-tients during clinical transfusion procedures.

Inhibitory effect of downregulating HMGB2 expression on epithelial-mesenchymal transition of liver cancer LM3 cells and its AKT/m TOR signaling pathway mechanism / 吉林大学学报(医学版)

Objective:To discuss the effect of downregulating of high mobility group box protein 2(HMGB2)expression on the biological behavior of the liver cancer cells and the epithelial-mesenchymal transition(EMT)process,and to clarify its mechanism.Methods:The human liver cancer LM3 cells at logarithmic growth phase were divided into negative control group and HMGB2 RNA interference group(HMGB2 siRNA group);the cells in two groups were transfected with RNA oligonucleotides(RNA oligos)with irrelevant sequences and RNA oligos designed to knock down HMGB2,and the Lipofectamine 2000 was regarded as the vector.The expression levels of HMGB2 mRNA and protein in the cells in two groups were detected by real-time fluorescence quantitative PCR(RT-qPCR)and Western blotting methods;cell scratch assay and Transwell chamber assay were used to detect the migration and invasion abilities of the cells in two groups;the expression levels of E-cadherin,N-cadherin,and Vimentin proteins and protein kinase B(AKT)/mammalian target of rapamycin(mTOR)pathway related proteins in the cells in two groups were detected by Western blotting method.Results:Compared with negative control group,the expression levels of HMGB2 mRNA and protein in the cells in HMGB2 siRNA group were significantly decreased(P<0.05),the cell scratch healing rate was significantly decreased(P<0.01),the number of invasion cells was significantly decreased(P<0.01),and the expression level of E-cadherin protein in the cells was significantly increased(P<0.01),while the expression levels of N-cadherin,Vimentin,mTOR,AKT,and phosphorylated AKT(p-AKT)proteins in the cells were significantly decreased(P<0.05 or P<0.01).Conclusion:Downregulating the expression of HMGB2 can reduce the migration and invasion abilities of the liver cancer LM3 cells and inhibit the EMT,and its mechanism may be related to regulating the expression of the AKT/mTOR pathway related proteins.
