RESUMEN
Objective@#To study the effect of low concentrations of sodium fluoride on the osteogenic/odontogenic differentiation of human dental pulp cells (hDPCs) in vitro.@*Methods@#This study was reviewed and approved by the Ethics Committee. hDPCs were cultured using a modified tissue explant technique in vitro. The effects of different concentrations of sodium fluoride on the proliferation of hDPCs were measured by methylthiazol tetrazolium (MTT) assay. Appropriate concentrations were added to the osteogenic/odontogenic differentiation induction medium, and the cells were induced in vitro. Alizarin red S staining was used to detect the osteoblastic/odontogenic differentiation ability of the cells, and the mRNA expression of the key differentiation factors was detected by RT-qPCR. Moreover, the expression of key molecules of endoplasmic reticulum stress (ERS) was detected by RT-qPCR and Western blot. The data were analyzed with the SPSS 18.0 software package.@*Results@#Low concentration of NaF (0.1 mmol/L) could stimulate cell proliferation in vitro, while a high concentration (5-10 mmol/L) could inhibit cell proliferation (P<0.05). According to the literature and the experimental data, 0.1 mmol/L NaF was selected as the following experimental concentration. The levels of alizarin red S staining were increased after NaF induction of mixed osteogenic/odontogenic differentiation in vitro. The mRNA expression levels of key molecules for osteogenic/odontogenic differentiation, dentin sialophosphoprotein (DSPP), bone sialoprotein (BSP) and osteocalcin (OCN), were increased (P<0.05). The mRNA levels of ERS markers (splicing x-box binding protein-1 (sXBP1), glucose-regulated protein 78 (GRP78) and activating transcription Factor 4 (ATF4) were increased in NaF-treated cells. The protein expression levels of key ER stress molecules (phosphorylated RNA-activated protein kinase-like ER-resident kinase (p-PERK), phosphorylated eukaryotic initiation factor-2α (p-eIF2α) and ATF4) were higher in NaF-treated cells.@*Conclusion@#A low concentration of NaF promotes the osteogenic/odontogenic differentiation of hDPCs and increases the level of ER stress.
RESUMEN
ObjectiveTo investigate the current status of first aid knowledge among middle-aged and elderly residents aged 50 and above in a community in Shanghai， in order to provide reference for improving the self-rescue and mutual aid capabilities of middle-aged and elderly residents. MethodsA multi-stage stratified random sampling method was used to conduct a survey on 335 residents aged 50 and above in a community in Shanghai using a self-made survey questionnaire. The current situation and related factors of emergency knowledge level of residents aged 50 and above in the community were comprehensively analyzed. ResultsFirst aid knowledge level of 335 residents aged 50 and above was low， and the rate of high cognitive level was only 24.18%. Univariate analysis showed that male residents had a higher awareness rate than female residents （P=0.044）， while residents aged 70 and above and 60‒ had lower awareness rates than residents aged 50‒ （P<0.05）. Residents with chronic diseases had a higher awareness rate than those who did not （P=0.031）. Residents with family members suffering from chronic diseases had a higher awareness rate than those without （P<0.001）. Experience of first aid training affected residents’ awareness of first aid （P=0.003）. ConclusionThe level of first aid knowledge among middle-aged and elderly residents aged 50 and above in the community is low. Age， the presence of chronic diseases in family members， and emergency training are independent and relevant factors that affect the awareness of first aid knowledge among middle-aged and elderly residents. The government and relevant institutions should explore the establishment of a standardized emergency response training system， implement classification and grading for middle-aged and elderly groups with different characteristics， and provide targeted emergency training to strengthen their self-rescue and mutual aid capabilities and improve the success rate of pre-hospital emergency care.
RESUMEN
The cultivation of medical humanistic quality is indispensable in the standardized training of pediatric residents, and it is urgent to explore new educational methods to improve their medical humanistic quality level. In this study, 60 standardized pediatricians participated in the standardized training, 36 in the experimental group received innovative interactive medical humanities education, while 24 in the control group were set up to receive traditional medical humanities education. Short-term and long-term test scores were conducted by questionnaire at the beginning of the standardized training and 2 years later. The results showed that there was no significant difference between the experimental group and the control group in the self-scores of professional quality, moral cultivation, communication skills, legal knowledge and innovative spirit (P>0.05) , but the scores of teaching teachers were improved except innovative spirit (P<0.05) . In addition, compared with the control group, the number of pediatricians with professional honor increased, the doctor-patient communication ability improved, the medical disputes reduced, and the family satisfaction improved in experimental group were increased (P<0.05) . These results indicated that innovative interactive medical humanistic education is an effective method to improve the medical humanistic quality of pediatric residents in standardized training.
RESUMEN
ObjectiveTo understand the awareness of knowledge about chronic obstructive pulmonary disease （COPD） and influencing factors among residents in Yangpu District， Shanghai. MethodsWe used cluster random sampling method to conduct face-to-face questionnaire surveys on selected household residents in 12 streets of Yangpu District. The survey questions included their understanding of COPD name， lung function test， and COPD related knowledge. Multivariate logistic regression analysis was used to analyze the influencing factors of awareness rate. ResultsA total of 1 440 people were ultimately included in the analysis， and the awareness rates of COPD name， lung function test， and COPD awareness were 19.93%， 18.61%， and 14.95%， respectively. Among the people who knew the name of COPD， awareness rate of shortness of breath or dyspnea was the highest （84.12%） in the three main symptoms of COPD. Among the main risk factors of COPD， second-hand smoke（86.78%）and smoking （85.82%） were the highest. The main ways to obtain knowledge of COPD names were through television （12.60%） and the internet （11.97%）. The results of multivariate logistic regression analysis showed that men were significantly higher than women in the awareness of COPD name， lung function test， and COPD knowledge， with the OR values of （OR=1.39， 95%CI：1.08‒1.79）， （OR=1.47，95%CI：1.12‒1.92） and （OR=1.37，95%CI：1.02‒1.84）， respectively. The awareness rate of COPD names and lung function tests was the highest among people aged ≥ 65 years old， while the awareness rate of COPD knowledge was the highest among people aged 35‒50 years old. The awareness rate of COPD names was the highest among people with college education or above， civil servants， teachers， and medical staff， people with an annual household income of 100 000‒200 000 yuan. ConclusionThe overall awareness rate of COPD names， lung function tests， and COPD related knowledge among residents in Yangpu District is still at a low level. We should intensify the promotion and education of COPD among key groups such as women， young people， and those with low income， in order to improve the overall awareness rate of COPD among the population.
RESUMEN
Introducción: la depresión es un trastorno cada vez más prevalente alrededor del mundo. Los médicos generales son los profesionales de la salud más consultados por pacientes deprimidos. Más del 70% de los pacientes con depresión son vistos por médicos generales y no por especialistas en Psiquiatría. Según estudios realizados en Buenos Aires, más del 25% de los pacientes internados en Servicios de Clínica Médica en hospitales generales presenta depresión. Estos pacientes suelen ser atendidos y seguidos por médicos en formación, sean residentes o concurrentes de Clínica Médica. El objetivo del trabajo fue analizar el conocimiento sobre los inhibidores selectivos de la recaptura de serotonina (ISRS) que tienen los médicos residentes y concurrentes de Clínica Médica de 5 hospitales de la Ciudad Autónoma de Buenos Aires (CABA) y describir el tratamiento de un paciente depresivo por ellos. Material y métodos: se realizó un estudio descriptivo de corte transversal con un muestreo de tipo no probabilístico. Se utilizó como instrumento de medición un cuestionario semiestructurado organizado en dos secciones, una de datos demográficos que permiten caracterizar la muestra. La otra, de 15 ítems, explora los conocimientos sobre los ISRS y el tratamiento de la depresión. Dicho cuestionario fue revisado por 4 expertos. El instrumento es anónimo. Se aplicó a 59 médicos en formación en Clínica Médica, residentes y concurrentes, de 5 hospitales de la CABA, que participaron de forma voluntaria, durante el período agosto-septiembre de 2022. Resultados: la mayoría de los médicos en formación en Clínica Médica no tratan cuadros depresivos y, ante un paciente deprimido, solicitan la evaluación por un especialista en Salud Mental. Solo un 6,8% lo medica con un antidepresivo. Más del 75% de la muestra refiere recordar los conocimientos que tiene sobre de los ISRS de la cursada de Farmacología y un 13,6 de la cursada de Psiquiatría en la Facultad de Medicina. Conclusión: se observa un conocimiento deficitario sobre los ISRS en médicos residentes y concurrentes de Clínica Médica. Se considera necesario reforzar la formación sobre depresión y manejo de antidepresivos durante la residencia/concurrencia de Clínica Médica. (AU)
Introduction: depression is an increasingly common disorder around the world. General practitioners are the most frequently consulted health professionals by depressed patients. More than 70% of all depressed patients receive treatment by general practitioners and not by psychiatric specialists. According to studies conducted in Buenos Aires, more than 25% of all patients admitted to the Clinical Services in public hospitals present depression. These patients are usually under the care and follow-up of clinical trainee physicians, residents, or interns.This study aimed to analyze the knowledge about selective serotonin reuptake inhibitors (SSRIs) of clinical trainee residents and interns in five hospitals in the Ciudad Autónoma de Buenos Aires (CABA) and to describe their treatment of a depressive patient. Material and methods: we conducted a descriptive cross-sectional study with a non-probabilistic sampling. We used a semi-structured questionnaire arranged into two sections as a measuring tool. One, with demographic data to describe the sample. The other, with 15 items, explores respondents' knowledge of SSRIs and the treatment of depression. Four experts reviewed the questionnaire, which was anonymous. We applied it to 59 clinical medical trainees, residents, and interns from five CABA hospitals who volunteered to participate during August-September 2022. Results: most clinical trainees do not treat depressive conditions and, when confronted with a depressed patient, request an assessment by a Mental Health specialist. Only 6.8% medicate the patient with an antidepressant. More than 75% of the sample reported remembering their knowledge of SSRIs from the Pharmacology course and 13.6% from the Psychiatry course at the School of Medicine. Conclusion: there is a deficient knowledge about SSRIs in trainee residents and interns of Clínica Médica. We believe it is necessary to reinforce training on depression and management of antidepressants during residency/internship practice in Clínica Médica. (AU)

Introducción: la simultaneidad de actividades entre las exigencias académicas y el adiestramiento médico durante las residencias provoca un elevado riesgo de desarrollar un desgaste profesional (o síndrome de burnout [SB]) en los médicos residentes. El objetivo fue identificar los factores psicosociales y socio- demográficos asociados al SB en médicos residentes. Materiales y métodos: estudio transversal y correlacional. Participaron 47 médicos residentes de un hospital público. Se aplicaron la Escala de Desgaste Ocupacional (EDO), el Inventario Multifásico de la Personalidad Minnesota-2 Forma Reestructurada (MMPI2-Rf) y un cuestionario sociodemográfico. Los datos se analizaron mediante la prueba de correlación no paramétrica de Spearman. Resultados: el 25.6 % de los participantes mostró burnout alto, y el 51 %, un agotamiento emocional alto. Respecto a los factores de personalidad y sociodemográficos asociados, solo mostraron relación significativa (p < 0.05) la escala de impulsividad (r = 0.341, p = 0.019) y las horas de ejercicio en la semana (r = −0.414, p = 0.004). Al segmentar por sexo, solo en los hombres del estudio existió una relación entre SB y psicoticismo (r = 0.468, p = 0.018), la disminución de la actividad física (r = −0.620, p = 0.001) y primeros años de residencia (r = −0.396, p = 0.050). Conclusiones: el alto agotamiento emocional de los residentes está asociado con problemas en el manejo de impulsos, distorsiones de la realidad (debido al psicoticismo), pertenecer a los primeros años de residencia y falta de ejercicio físico. Se requiere especial atención a la salud física y mental de estos profesionales
Introduction: The simultaneity of activities between academic demands and medical training during residencies is a high risk of developing burnout syndrome (BS) among resident physicians, which decreases their quality of life. This study aimed to identify the psychosocial and sociodemographic factors associated with BS among resident physicians from a public hospital. Materials and methods: This cross-sectional and correlational study involved 47 resident physicians. The Occupational Burnout Scale (EDO), the Minnesota Multiphasic Personality Inventory-2 Restructured Form, and a sociodemographic questionnaire were applied. The data were analyzed by using nonparametric Spearman's correlation test. Results: We found that 25.6% of the participants had a high level of burnout, while 51% showed a high level of emotional exhaustion. Regarding personality and sociodemographic factors associated with BS, only the impulsivity scale (r = 0.341; p = 0.019) and the hours of exercise performed in a week (r = −0.414; p = 0.004) showed a significant relationship (p < 0.05). When segmented by sex, a relationship between BS and psychoticism (r = 0.468; p = 0.018), decreased physical activity (r = −0.620; p = 0.001), and first years of residence (r = −0.396; p = 0.050) were noted only in men. Conclusions: A high level of emotional exhaustion was evidenced among the medical residents in relation to the development of their activities, which were associated with problems in the management of impulses, distortions of reality (due to psychoticism), belonging to the first years of residency, and the lack of physical exercise. Hence, special attention must be given to the physical and mental health of medical residents

Purpose: During the coronavirus disease 2019 (COVID?19) pandemic, private practice, inpatient consult services, and academic residency programs in ophthalmology saw a decrease in patient encounters. This study elucidates how community hospital ophthalmology consult (OC) services were affected during the pandemic. We aim to determine whether there was a change in resident OC volume in a community?based ophthalmology program consult service during the COVID?19 pandemic. Secondary objectives included analyzing the change in the types of diagnoses and the number of patients seen for diabetic retinopathy over the same time. Methods: A retrospective cross?sectional study was conducted reviewing the electronic health record (EHR) charts from OCs for the period 2017–2021. Records were categorized by referral source and the nature of OCs (trauma, acute, or chronic); OCs were further grouped by year and weak of referral. An intermonth analysis of weekly OC counts in each category was performed for the average number of consults in February–April 2017–2019 and for February–April 2020. A one?tailed t?test was performed. All t?tests assumed equal variances. Results: Weekly OCs in 2020 revealed no statistically significant differences in overall cases or in acute or chronic cases when the volume before the COVID?19 pandemic was compared to the volume after the onset of the pandemic. However, a statistically significant increase in the average weekly trauma cases was noted when 2020 (an average of 2.7 cases per week) was compared to the weekly average for the same weeks of years 2017– 2019 (0.4; P = 0.016). This statistically significant increase in trauma in 2020 disappeared when comparing weeks 11–17 in 2020 (2.2 cases per week) and the average of 2017–2019 (1.1).Conclusion: This report outlines no significant change in OCs before and after the onset of the pandemic compared to three previous years. There was, however, an increase in trauma consults during the pandemic and an increase in the number (though not the proportion) of diabetic retinopathy (DR+) patients seen by residents. This report uniquely describes no significant changes in the resident volume of patients seen during the COVID?19 global pandemic
RESUMEN
Background and Objectives: Pathology is a broad subject consisting of various branches, such as hematology, clinical pathology, biochemistry, histopathology, cytology, blood banking, and others. All the subspecialties are difficult to cover in depth in a 3-year MD Pathology course and curriculum. Hence, it was decided to investigate whether the MD Pathology curriculum is able to meet the challenges of today's laboratory medicine practice. So, a survey was conducted among newly qualified pathologists who have passed their exam within last 5 years. Purpose was to know their views about MD Pathology curriculum with special emphasis on challenges they face during their day-to-day practice. Materials and Methods: Study is designed as cross-sectional survey conducted via web-based Google forms questionnaire. Study population is pathologists qualified within last 5 years. A convenience sample of eligible pathologists was taken by sending a web-based Google form to various pathology groups on social media apps. Data were collected in the Google spreadsheet software and various responses were summarized as percentages, graphs, and pie-charts as necessary. Chi square test was used to find the significance of difference in responses from government, private, and deemed university respondents. Results: Different numbers of responses were received to different survey questions. Out of 187 respondents, 65 (34.8%) worked in a hospital-based laboratory, 61 (32.6%) did jobs in a private laboratory, 49 (26.2%) worked in a medical college, and 37 (19.8%) worked in their own private laboratories. Out of 193 respondents, 158 (81.9%) were working in hematology, 149 (77.2%) in clinical pathology, 139 (72%) in cytopathology, 118 (61.7%) in histopathology, whereas 103 (53.4%) worked in clinical biochemistry, and least number of respondents, i.e., 38 (19.7%) were working in blood bank. Almost all the respondents had overlapping work in hematology and other areas. The level of confidence rated by the respondents was best in hematology, followed by clinical pathology; it was least for clinical biochemistry and blood bank. Out of 192 respondents, 64.1% (123) felt that the curriculum does not equip them for lab management and administration, 21.9% (42) felt that the curriculum somewhat equipped them; whereas only 14.1% (27) felt that curriculum equips them for this task. There were 191 responses to the question regarding satisfaction with MD Pathology curriculum; out of which, 51.8% (99) were not satisfied, 24.6% (47) said they may be satisfied, whereas 23.6% (45) were satisfied with the curriculum. There was no significant difference in responses from government, private, and deemed university respondents. Conclusions: The graduating MD Pathology students expressed confidence in reporting routine cases of hematology, clinical pathology, routine cytology, and histopathology. However, there is difficulty in clinical biochemistry, blood banking, and reporting of malignancies. The laboratory management and administration, communication skills, and quality assurance are also other areas of weakness. MD Pathology program needs more focus on these weaknesses, so that newly qualified graduate would feel confident in day-to-day laboratory working.
RESUMEN
Objective:To explore the distribution features of resident CD8 + T cells infiltration in human esophageal cancer tissues and its clinical significance. Methods:Data from the Cancer Genome Atlas database were retrieved, the correlation between CD103 + CD8 + T cells and infiltration degree of conventional type 1 dendritic cell (cDC1), conventional type 2 dendritic cell (cDC2), type 3 dendritic cell(DC3) was investigated. From January 2006 to December 2008, 78 esophageal cancer tissues and 75 adjacent normal tissues from 78 esophageal cancer patients were collected by Shanghai Outdo Biotechnology Co., Ltd, the clinical data of patients was followed up by telephone until July 2015. The distribution of CD8 + T cells and CD103 + CD8 + T cells in cancer tissues and adjacent normal tissues was detected by multi-color labeling techniques and multispectral tissue imaging. The differences of the number and the ratio of CD8 + T cells and CD103 + CD8 + T cells in cancer tissues and adjacent normal tissues were compared. The Kaplan-Meier survival curves of patients with tissue infiltration of CD8 + T cells and CD103 + CD8 + T cells at different levels were drawn through the R language " survminer" package, and the best cut-off value was obtained. TNM stage, pathological stage and other clinical parameters of patients with high and low infiltration of CD8 + T cells, CD103 + CD8 + T cells were compared. Wilcoxon rank sum test, chi-square test, log-rank test and Cox proportional risk regression model statistical analysis were used to evaluate the prognostic value of the above indicators. Spearman correlation analysis was used for correlation analysis. Results:In the cancer tissues of patients with esophageal cancer, the infiltration degree of CD103 + CD8 + T cells was positively correlated with the infiltration degree of cDC1 cells, cDC2 cells and DC3 cells ( r=0.67, 0.53 and 0.47, all P<0.001). The percentage of CD8 + T cells in all cells in the whole tissue core of tumor tissues (63.09% (42.14%, 76.21%)) was higher than that of adjacent normal tissues (2.56% (1.68%, 5.38%)), and the difference was statistically significant ( U=41.00, P<0.001). The proportion of CD103 + CD8 + T cells in all cells in the whole tissue core of tumor tissues (7.92% (1.60%, 20.61%)) was higher than that of adjacent normal tissues (0.04% (0.01%, 0.10%)), and the difference was statistically significant ( U=857.50, P<0.001). The percentage of high CD8 + T cells infiltration in esophageal cancer tissues of patients with pathological stage Ⅰ+ Ⅱ was lower than that of patients with stage Ⅲ+ Ⅳ (57.9%, 33/57 vs. 85.7%, 18/21); the percentage of high CD103 + CD8 + T cells in CD8 + T cells in esophageal cancer tissues of patients with TNM stage Ⅰ+ Ⅱ was lower than that of patients with stage Ⅲ+ Ⅳ (21.6%, 8/37 vs. 48.8%, 20/41), and the differences were both statistically significant ( χ2=5.25 and 6.23, P=0.022 and 0.013). The results of Kaplan-Meier survival analysis and univariate Cox proportional risk regression model showed that the overall survival (OS) of patients with high CD8 + T cell infiltration was longer than that of patients with low CD8 + T cell infiltration ( HR=0.57, 95% confidence interval (95% CI) 0.34 to 0.96, P=0.034). There was no significant difference in OS between patients with high CD103 + CD8 + T cell infiltration and patients with low CD103 + CD8 + T cell infiltration ( HR=0.66, 95% CI 0.40 to 1.08, P>0.05). Conclusion:The high infiltration of CD103 + CD8 + T cells in esophageal cancer tissues are expected to be used as a prognostic predictor for patients with esophageal cancer, which is an important component of anti-tumor immune response in tumor microenvironment of esophageal cancer.

RESUMEN
Objective:To understand the effect of standardized residency training for residents with different identity types, and put forward targeted optimization and improvement measures to achieve the homogenization of training effect.Methods:Combined with literature review and expert consultation results, a self-designed questionnaire was conducted for 324 residents who completed their courses in 2019 and 2020. The effective recovery rate of the questionnaire was 87.65%. By comparing the passing rate of first-time medical admission and completion examination of different identity types, and the training standards of six core competencies, the training effect conclusion was drawn. T-test and Fisher exact probability test were also made by SPSS 21.0. Results:The passing rates of first-time doctors and completion examinations were higher in professional masters and units than in the general population, with the highest passing rates reaching 100% (10/10) and 97.3% (72/74) respectively. There was no statistical difference between the passing rates of residents with different identity types. The overall standard of the six core competencies of the integrated professional masters was better than that of the society and unit personnel. There were statistical differences between the groups in the training standards of the four abilities of the residents with different identity types in professional literacy ( P=0.048), patient management ( P=0.030), communication and cooperation ( P=0.026) and learning promotion ( P=0.003). There was no significant difference in professional ability ( P=0.131) and teaching ability ( P=0.061). Conclusion:There is no difference in the passing rate of residents with different identity types in a military hospital, which achieves the goal of homogenization training to a certain extent. However, there are obvious differences in the standards of the six core competencies, and further optimization measures need to be explored.

RESUMEN
Objective:To understand the current situation and influencing factors of depression among residents in Chongqing, and to explore the relationship between depression and administration satisfaction of the standardized residency training.Methods:Stratified random cluster sampling was used to select 372 residents currently participating the standardized residency training in Chongqing. The patient health questionnaire (PHQ-9) and administration satisfaction of residency training questionnaire were used to conduct a cross-sectional survey on the depression status and satisfaction of residents in Chongqing. SPSS 21.0 software package was used for partial correlation analysis and binary logistic regression analysis to explore the relationship between depression and administration satisfaction of the standardized residency training.Results:Among the 372 residents, 218 had mild depression and above (58.60%). There was a significant difference in the incidence of depression among residents of different ages, educational background, marital status, working hours and administration satisfaction of residency training ( χ2 = 23.02, 17.35, 12.24, 21.70, 95.20; P = 0.028, 0.027, 0.016, 0.041, <0.001 respectively). Partial correlation analysis showed that there was a negative correlation between the total score of depression and the five aspects of the administration satisfaction (total score, instructors, training base, managers and training income) ( r=-0.52, -0.45, -0.47, -0.45, -0.40, all P<0.01). In the binary logistic regression analysis of depression and satisfaction,the satisfaction had a negative impact on depression, and its B value was -1.71, and OR value was 0.18, P<0.001. Conclusion:The incidence of depression among residents in Chongqing is high. Age, educational background, marital status, working hours and administration satisfaction are related to the degree of depression. And the higher the degree of depression, the lower the administration satisfaction of residents. Relevant departments should pay attention to the mental health of residents and improve the quality of standardized residency training.

RESUMEN
ObjectiveTo understand the distribution characteristics of soil metal pollution around an abandoned rare earth ore in Jiangxi and the health impact on the surrounding residents. MethodsAccording to the distribution of abandoned rare earth ore， the village was divided into mining and non-mining areas. The prevalence of chronic diseases among residents over 15 years old in the village was collected through a self-designed questionnaire. Twenty-three soil samples were collected. The contents of rare earth metals （including lanthanum， cerium， praseodymium， and neodymium） and heavy metals （including arsenic （metalloids）， cadmium， and lead） in the soil samples were determined by inductively coupled plasma mass spectrometry （ICP-MS）. ResultsThe metal content showed a cumulative increasing trend. One of the23 sampling sites showed mild cadmium pollution. Compared with non-mining farmland， the metal content of farmland soil around the abandoned rare earth mine was relatively higher. The residents' top six self-reported chronic diseases were hypertension， chronic bronchitis， diabetes， stroke， hyperlipidemia， and cataract. The prevalence of hypertension in mining area was higher than non-mining area （χ2=4.141， P=0.042）. The main related factors for hypertension in residents were the increase in age （OR=14.576， 95%CI： 2.773‒76.605） and body mass index （OR=3.147， 95%CI： 1.121‒8.835）. ConclusionAbandoned rare earth ore may have a potential impact on the health of surrounding residents.
