RESUMEN

With the development of science and technology, wearable electronics are increasingly widely used in medical, environmental monitoring, and other fields. Thus, the demand for flexible electrodes is increasing. The two-dimensional material Ti3C2Tx has attracted much attention in the manufacture of flexible electrodes due to its excellent mechanical and electrical properties. However, the brittleness of pure Ti3C2Tx films has become a major obstacle for their use as flexible electrodes in wearable devices. Therefore, solving the brittleness problem of flexible electrodes based on Ti3C2Tx while maintaining the excellent performance of Ti3C2Tx has become an urgent problem. To solve this problem, Ti3C2Tx was compounded with waterborne polyurethane (WPU), and a Ti3C2Tx-WPU composite film with a hierarchical structure was constructed by evaporation-assisted self-assembly. The Ti3C2Tx-WPU composite film not only retains the excellent electrical conductivity of Ti3C2Tx (100 S m-1) but also has flexibility (20 MJ m-3). Furthermore, the Ti3C2Tx-WPU composite film is applied to functional devices such as contact pressure sensors and non-contact proximity sensors. Finally, the Ti3C2Tx-WPU composite film wearable device demonstrates its practical application potential in the field of wearable devices.

RESUMEN

BACKGROUND: The study aims to investigate the long-term impact of lifestyle-related factors and physical health on life satisfaction and depressive symptoms among Chinese community-dwelling older adults. METHODS: Using data from the China Health and Retirement Longitudinal Study (CHARLS), the analytic sample of this study included 1,068 older adults who had participated in the surveys in both 2011 and 2018. Multivariate regression was employed to analyze both cross-sectional and longitudinal relationships between lifestyle-related factors, physical health, and subjective well-being - specifically depressive symptoms and life satisfaction. Additionally, the model tested how these factors correlate with life satisfaction across different groups of depressive symptom changes among older adults, categorized as not at risk of depression, intermittent depression, and chronic depression. RESULTS: Multimorbidity was significantly related to baseline and follow-up depressive risk in older adults. Shorter sleep duration was associated with baseline depression risk. Current alcohol drinkers reported significantly more severe depressive symptoms than non-drinkers. At baseline, current smokers were more likely to have a lower degree of life satisfaction than nonsmokers. Among older adults with chronic depression at the 7-year follow-up, former smokers tended to have lower life satisfaction than nonsmokers. CONCLUSIONS: Our findings identified drinking alcohol and having a shorter sleep duration as modifiable lifestyle-related risk factors for late-life depression and smoking as a detrimental factor for life satisfaction in older Chinese adults. Multimorbidity was a significant predictor of more depressive symptoms. Our findings have implications for future psychosocial interventions that target the alleviation of depressive symptoms and the promotion of life satisfaction in older Chinese people based on their different long-term mental and physical health conditions.

RESUMEN

Background and Objectives: Depressive symptoms are common in older adults, and often co-occur with other mental health problems. However, knowledge about depressive symptom-domains and their associations with other conditions is limited. This study examined depressive symptom-domains and associations with anxiety, cognition, and loneliness. Research Design and Methods: A sample of 3,795 participants aged 60 years and older were recruited from the community in Hong Kong. They were assessed for depressive symptoms (Patient Health Questionnaire-9 [PHQ-9]), anxiety (Generalized Anxiety Disorder 7-item), loneliness (UCLA 3-item), and cognition (Montreal Cognitive Assessment 5-Minute Protocol). Summary descriptive statistics were calculated, followed by confirmatory factor analysis of PHQ-9. Multiple Indicators Multiple Causes analysis was used to examine the associations between mental health conditions in the general sample and subgroups based on depressive symptom severity. Results: A 4-factor model based on the Research Domain Criteria showed the best model fit of PHQ-9 (χ2/df = 10.63, Root-Mean-Square Error of Approximation = 0.05, Comparative Fit Index = 0.96, Tucker-Lewis Index = 0.93). After adjusting for demographics, 4 depressive symptom-domains were differentially associated with anxiety, loneliness, and cognition across different depression severity groups. The Negative Valance Systems and Internalizing domain (NVS-I; guilt and self-harm) were consistently associated with anxiety (ß = 0.45, 0.44) and loneliness (ß = 0.11, 0.27) regardless of depression severity (at risk/mild vs moderate and more severe, respectively, all p < .001). Discussion and Implications: The consistent associations between the NVS-I domain of depression with anxiety and loneliness warrant attention. Simultaneous considerations of depressive symptom-domains and symptom severity are needed for designing more personalized care. Clinical Trials Registration Number: NCT03593889.

RESUMEN

Stable isotope-assisted metabolomics (SIAM) is a powerful tool for discovering transformation products (TPs) of contaminants. Nevertheless, the high cost or lack of isotope-labeled analytes limits its application. In-house H/D (hydrogen/deuterium) exchange reactions enable direct 2H labeling to target analytes with favorable reaction conditions, providing intuitive and easy-to-handle approaches for environmentally relevant laboratories to obtain cost-effective 2H-labeled contaminants of emerging concern (CECs). We first combined the use of in-house H/D exchange and 2H-SIAM to discover potential TPs of 6PPD (N-1,3-dimethylbutyl-N'-phenyl-p-phenylenediamine), providing a new strategy for finding TPs of CECs. 6PPD-d9 was obtained by in-house H/D exchange with favorable reaction conditions, and the impurities were carefully studied. Incomplete deuteride, for instance, 6PPD-d8 in this study, constitutes a major part of the impurities. Nevertheless, it has few adverse effects on the 2H-SIAM pipeline in discovering TPs of 6PPD. The 2H-SIAM pipeline annotated 9 TPs of 6PPD, and commercial standards further confirmed the annotated 6PPDQ (2-anilino-5-(4-methylpentan-2-ylamino)cyclohexa-2,5-diene-1,4-dione) and PPPD (N-phenyl-p-phenylenediamine). Additionally, a possible new formation mechanism for 6PPDQ was proposed, highlighting the performance of the strategy. In summary, this study highlighted a new strategy for discovering the TPs of CECs and broadening the application of SIAM in environmental studies.

RESUMEN

PURPOSES: To investigate quality of life (QoL) of family caregivers of people with schizophrenia and examine the influencing factors of the QoL in a Chinese rural area. METHODS: This study included people with schizophrenia (n = 269) and their family caregivers (n = 269) from Xinjin district, Chengdu, China. Family caregivers' QoL was measured by the World Health Organization Quality of Life-Brief Form and its influencing factors was analyzed by the multivariate regression. RESULTS: Family caregivers of people with schizophrenia had very poor QoL across four domains. The regression analysis showed that physical domain of QoL was significantly associated with age, psychiatric symptoms of people with schizophrenia, and caregiving burden of family caregivers (p < 0.05). Psychological domain of QoL was significantly related to family caregivers' affiliate stigma, caregiving burden, and psychiatric symptoms of people with schizophrenia (p < 0.05). Social domain of QoL was significantly associated with age and psychiatric symptoms of people with schizophrenia, and affiliate stigma of family caregivers (p < 0.05). Environmental domain of QoL was significantly related to age and psychiatric symptoms of people with schizophrenia, and family caregivers' caregiving burden (p < 0.05). CONCLUSION: Family caregivers of people with schizophrenia had poor QoL in rural China. Family caregivers' QoL is significantly impacted by age and psychiatric symptoms of people with schizophrenia, caregivers' affiliate stigma and caregiving burden. Providing social support and psychosocial interventions for family caregivers of people with schizophrenia might be crucial to improve their QoL and caregiving.

RESUMEN

AIMS: Ulcerative colitis (UC) is a chronic inflammatory bowel disease (IBD) caused by multiple factors. Studies have shown that epithelial cell damage was associated with ferroptosis in UC. Therefore, our research focused on the effects and mechanism of iron chelator deferasirox in UC. MAIN METHODS: The UC model was induced by 2.5 % dextran sulfate sodium salt (DSS) and administered with deferasirox (10 mg/kg) for 7 days. Histological pathologies, inflammatory response, ferrous iron contents, oxidative stress and ferroptosis regulators were determined. Intestinal microbiota alteration and short-chain fatty acids (SCFAs) production were analyzed through 16S rRNA gene sequencing and targeted metabolomics. KEY FINDINGS: Deferasirox significantly relieved the DSS-induced UC in mice, as evidenced by weight loss, survival rate, colon length shortening disease activity index (DAI) score and histology score. Deferasirox treatment reduced the level of pro inflammatory cytokines (IL-1ß, IL-6, TNF-α and INF-γ). Ferroptosis was induced in mice with UC, as evidenced by ferrous iron accumulation, increased ROS production, SOD and GSH depletion, decreased the expression of GPX-4 and FTH, accompanied by increased expression of TF. Deferasirox treatment strongly reversed the alterations caused by ferroptotic characteristics in DSS-induced mice. Moreover, deferasirox treatment reshaped the composition of intestinal microbiota. The results revealed the genera of norank_f__Muribaculaceae, Lachnospiraceae_NK4A136_group, Prevotellaceae_UCG-001, Odoribacter and Blautia were increased distinctly, while Escherichia-Shigella and Streptococcus were significantly decreased by deferasirox treatment. Targeted metabolomics analysis indicated the SCFAs production enhanced in deferasirox-treated mice. SIGNIFICANCE: Our results suggested that deferasirox could treat DSS-induced UC in mice by inhibiting ferroptosis and improving intestinal microbiota.

RESUMEN

Awareness of COVID-19 infection risk and oscillation patterns ('waves') may affect older people's mental health. Empirical data from populations experiencing multiple waves of community outbreaks can inform guidance for maintaining mental health. This study aims to investigate the effects of COVID-19 infection risk and oscillations on depression among community-dwelling older people in Hong Kong.A rolling cross-sectional telephone survey method was used. Screening for depression risk was conducted among 8,163 older people (age ≥ 60) using the Patient Health Questionnaire-2 (PHQ-2) from February to August 2020. The relationships between PHQ-2, COVID-19 infection risk proxies - change in newly infected cases and effective reproductive number (Rt), and oscillations - stage of a 'wave' reported in the media, were analysed using correlation and regression.8.4% of survey respondents screened positive for depression risk. Being female (ß = .08), having a pre-existing mental health issue (ß = .21), change in newly infected cases (ß = .05), and screening during the latency period before the media called out new waves (ß = .03), contributed to higher depression risk (R2 = .06, all p <.01).While depression risk does not appear alarming in this sample, our results highlight that older people are sensitive to reporting of infection, particularly among those with existing mental health needs. Future public health communication should balance awareness of infection risks with mental health protection.

RESUMEN

A Gram-negative, aerobic, nonmotile, rod-shaped and yellow-pigment-producing bacteria was isolated from Baima snow mountain of Diqing Tibetan Autonomous Prefecture in Yunnan province, south-west China and characterized using a polyphasic approach. The results of 16S rRNA gene sequence similarity analysis showed that strain YIM B04101T was closely related to the type strain of Dyadobacter koreensis DSM 19938T (97.81%) and Dyadobacter frigoris AR-3-8T (97.95%). The predominant respiratory quinone was menaquinone-7 (MK-7). The major polar lipid was phosphatidylethanolamine. The major fatty acids were summed feature 3 (C16:1ω7c/C16:1ω6c), C18:1ω9c and C16:0. The DNA G + C content was 43.5 mol%. Phylogenetic analysis based on 16S rRNA gene sequences indicated that the strain YIM B04101T belonged to a cluster comprising species of the genus Dyadobacter. However, it differed from its closest relative, Dyadobacter koreensis KCTC 12537T and Dyadobacter frigoris AR-3-8T, in many physiological properties. Based on these phenotypic characteristics and phylogenetic distinctiveness, strain YIM B04101T is considered to be a novel species of the genus Dyadobacter, for which the name Dyadobacter diqingensis sp. nov. is proposed. The type strain is YIM B04101T (= CGMCC 1.19249T = CCTCC AB 2021270).

RESUMEN

Paragonimiasis, which is caused by Paragonimus, is considered to be a neglected tropical disease by the World Health Organization. The pathogenicity of Paragonimus mainly manifests as mechanical damage and immunotoxicity caused by adult worms and larvae. However, microbiota associated with Paragonimus and potential disturbance of host microbiota after infection are unknown. Paragonimus proliferus is a rare species, and its successful infection rate in experimental rats is 100%. In the current study, we compared the microbial community in lung tissues, small intestine contents, and fecal samples from Sprague Dawley (SD) rats with and without P. proliferus infection. To determine the impact of P. proliferus on the microbial community in rats, we identified the microbiota in adult worms of P. proliferus via high-throughput sequencing. Results showed dramatic differences in the composition of microbiota in lung tissues between infected and uninfected rats. Paragonimus metacercariae introduced both environmental and gut microbes into the lung tissues of rats. Many potentially pathogenic microbes were also found in the lung of infected rats. Paragonimus infection increased the chances of potentially pathogenic microbiota invading and colonizing the lungs. However, for the purpose of long-term parasitism, there might be a complex interrelationship between Paragonimus and microorganisms. Our study might shed lights on the understanding of the pathogenicity of Paragonimus.

RESUMEN

Ginsenoside Rg1 is the active ingredient of the plant named genus Panax (ginseng), which exhibited significant bioactivities, including anti-inflammatory, antioxidation, and anti-diabetic effects. Herein, 4-week treatment of ginsenoside Rg1 remarkably decreased blood glucose levels and improved the resistance of insulin, oxidative stress, and inflammation along with lipid profile in T2D rats triggered via high-fat diet and streptozotocin (STZ). Ginsenoside Rg1 supplementation improved the intestinal microbial composition induced by type 2 diabetes (T2D), which increased the proportions of Lachnospiraceae_NK4A136_group and Lachnoclostridium and decreased the proportions of Lactobacillus. Additionally, Spearman's correlation test between the gut microflora and biomedical assays (|r| > .5) revealed that the Lachnospiraceae_NK4A136_group, Roseburia, and Romboutsia greatly affect intestinal microbiota, which may play pivotal roles in preventing T2D. Our findings illustrate the use of ginsenoside Rg1 as a dietary supplement along with prospective prebiotics due to its ability to alter the gut microflora and alleviate T2D-linked biochemical abnormalities. PRACTICAL APPLICATIONS: This was the first study to elucidate the influences of ginsenosides Rg1 in improving the intestinal microbiota of T2D in SD rats. The data illustrated that the ginsenosides Rg1 remarkably increased the proportions of SCFAs producing bacteria. Hence, ginsenoside Rg1 could be used as a potential prebiotic in the treatment of T2D through alteration of intestinal microbiota.

RESUMEN

BACKGROUND: We aimed to explore the long-term caregiving experiences of family caregivers of people with schizophrenia (PwS) in terms of both positive and negative aspects. METHOD: Utilising a purposive sampling method, we conducted in-depth interviews with 20 family caregivers of persons who had suffered from schizophrenia for more than 20 years. We empirically investigated their retrospective experiences of caregiver-patient interactions during a long period of family caregiving. We audio-recorded and transcribed the interviews into text. We thematically coded and analysed the transcribed text using a four-phase method of theme development. FINDINGS: Schizophrenia might not only generate a caregiving burden, affect caregivers' psychological status, and accordingly influence their coping strategies, but also have short- or long-term patient-related consequences. DISCUSSION: Family caregivers should develop their stress management skills to cope with relevant life changes and increase their knowledge of the potential psychological consequences for care recipients resulting from negative caregiving strategies during home-based practice. Care recipients with schizophrenia in a relatively stable status should be empowered to take care of themselves. More effective family-based interventions for psychiatric nursing or individualised training for symptom management should be tailored to serve families' diverse needs.

RESUMEN

BACKGROUND: Little is known about how sociodemographic and clinical factors affect the caregiving burden of persons with schizophrenia (PwSs) with transition in primary caregivers. AIMS: This study aimed to examine the predictive effects of sociodemographic and clinical factors on the caregiving burden of PwSs with and without caregiver transition from 1994 to 2015 in rural China. METHOD: Using panel data, 206 dyads of PwSs and their primary caregivers were investigated in both 1994 and 2015. The generalised linear model approach was used to examine the predictive effects of sociodemographic factors, severity of symptoms and changes in social functioning on the caregiving burden with and without caregiver transition. RESULTS: The percentages of families with and without caregiver transition were 38.8% and 61.2%, respectively. Among families without caregiver transition, a heavier burden was significantly related to a larger family size and more severe symptoms in PwSs. Deteriorated functioning of 'social activities outside the household' and improved functioning of 'activity in the household' were protective factors against a heavy caregiving burden. Among families with caregiver transition, younger age, improved marital functioning, deteriorated self-care functioning, and better functioning of 'social interest or concern' were significant risk factors for caregiving burden. CONCLUSIONS: The effects of sociodemographic and clinical correlates on the caregiving burden were different among families with and without caregiver transition. It is crucial to explore the caregiver arrangement of PwSs and the risk factors for burden over time, which will facilitate culture-specific family interventions, community-based mental health services and recovery.

RESUMEN

Albeit poverty reduction has been listed as an overarching objective in many countries' development plans, little is known about how development could shape poverty dynamics in disadvantaged groups. Guided by a modified capability framework, this study aimed to explore the long-term experiences of poverty dynamics in severe mental illness. Semi-structured interviews were carried out with 20 caregivers who provided care for persons with severe mental illness in Chengdu, China. Their perceptions on development, the illness, and social security were addressed. Content analysis was employed to analyze data. Participants experienced an overall improvement of life quality due to changes on urban infrastructure and transformed lifestyle. However, they were more disadvantaged while facing ability-based opportunities. These families were hindered from transferring opportunities into incomes. Negative impacts of the illness were also reflected in multiple stigma and conversion difficulties. Additionally, the high threshold for payment made those inclusive social security policies not inclusive for them. Poverty associated with severe mental illness was unlikely to be alleviated automatically within the process of development. Social isolation and high caregiving burden had aggravated poverty for those disadvantaged families. Poverty alleviation should be closely linked to the improvement in social policies in China.

RESUMEN

A novel Gram-stain-negative, aerobic, motile and rod-shaped bacterium, designated as strain YIM B00319T, was isolated from a sediment sample obtained from Wuzunbulake salt Lake in Xinjiang Uygur Autonomous Region, northwest China. Phylogenetic analysis based on 16S rRNA gene sequences along with the whole genome showed that strain YIM B00319T belongs to the family Bacillaceae and was most closely related to Bacillus horti K13T and Caldalkalibacillus mannanilyticus JCM 10596T, with sequence similarities of 95.7% and 94.6%, respectively. The genome of strain YIM B00319T was 3.77 Mbp with a DNA G + C content of 43%. Strain YIM B00319T grew at 15-45 ℃, pH 7.0-9.5 and with 3-11% (w/v) NaCl. The major respiratory quinone of strain YIM B00319T was MK-7, and the major fatty acids (> 10%) were iso-C15:0, anteiso-C15:0, and summed feature 3 (C16:1 ω6c and/or C16:1 ω7c). The main polar lipids were phosphatidylethanolamine (PE), phosphatidylglycerol (PG), and diphosphatidylglycerol (DPG). The cell-wall peptidoglycan contained meso-diaminopimelic acid. On the basis of the phenotypic, chemotaxonomic, genomic, and phylogenetic information, strain YIM B00319T represents a novel species of the genus Caldalkalibacillus, for which the name Caldalkalibacillus salinus sp. nov. is proposed. The type strain is YIM B00319T (= CGMCC 1.18750T = NBRC 115338T).

RESUMEN

This study aimed to conduct a quantitative synthesis of the clinical correlates of caregiver burden in schizophrenia studies published in the last two decades. Derived from eight electronic databases, this meta-analytic review revisits 34 English articles published from 2000 to 2020 relevant to family caregiver burden in the schizophrenia field. The Newcastle-Ottawa Scale (NOS) was used to assess study quality. The pooled effect sizes of the selected studies ranged from -0.390 to 0.751. The results indicated a significant association between a heavier burden and disease-related risk factors, including more severe symptoms, greater general psychopathology, greater severity of functional impairment, and longer duration of illness. The results show moderating effects of study characteristics (i.e., study quality, participants, and location) on the correlations between these disease-related risk factors and caregiver burden. This review highlights the roles of study characteristics in affecting the inconsistent results for the effects of disease-related risk factors on caregiver burden in families of patients with schizophrenia. Psychosocial interventions are essential for family caregivers of persons with schizophrenia. Future studies incorporating random samples from both high-income and low-to-middle-income countries will be crucial to understand the effects of cultural contexts on caregiver burden in families of persons with schizophrenia.

RESUMEN

This study examines the 21-year longitudinal impacts and predictive effects of family caregiver transition and the presence of family caregiving on the clinical status of persons with schizophrenia (PwSs) in a rural area of China. Using panel data derived from the Chengdu Mental Health Project (CMHP), 250 dyads of PwSs and their family caregivers were investigated in 1994 and 2015. The Positive and Negative Syndrome Scale (PANSS) and the Global Assessment of Functioning (GAF) were utilized. The generalized linear model (GLM) approach was used. The results of this study showed that more severe symptoms in PwSs were found to be significantly predicted by older age and nonmarried status at baseline. Compared with "spousal caregiving in two waves," the PANSS score was significantly higher in the "transition into sibling caregiving" group. A higher degree of psychosocial functioning was found to be significantly predicted by marital status, shorter duration of illness, and better mental status. Compared with "spousal caregiving in two waves," the GAF score was significantly lower in the "transition into parental caregiving" group. The presence of family caregiving was not a significant predictor of the severity of symptoms or psychosocial functioning in the PwSs. In conclusion, this study shows the 21-year predictive effects of family caregiver transition on the mental status of PwSs but not the presence of family caregiving. Psychosocial interventions and specific guidance should be provided to family caregivers to enhance their quality of caregiving and improve the prognosis of PwSs during long periods of home care.


En este estudio se analizan los efectos longitudinales a 21 años y los efectos pronósticos de la transición de los cuidadores familiares y la presencia de cuidado familiar en el estado clínico de las personas con esquizofrenia en un área rural de China. Utilizando datos de panel extraídos del Proyecto de salud mental de Chengdu (Chengdu Mental Health Project, CMHP), se investigaron 250 díadas de personas con esquizofrenia y sus cuidadores familiares en 1994 y 2015. Se utilizó la Escala de síndrome positivo y negativo (Positive and Negative Syndrome Scale, PANSS) y la Evaluación global del funcionamiento (Global Assessment of Functioning, GAF). También se utilizó el método de modelo lineal generalizado. Los resultados de este estudio demostraron que los síntomas más intensos en las personas con esquizofrenia fueron pronosticados principalmente por la edad avanzada y el estado de soltería en el momento basal. En comparación con el grupo de "cuidado de los cónyuges en dos intervalos", el puntaje de la PANSS fue considerablemente más alto en el grupo de "transición al cuidado de los hermanos". Se descubrió que principalmente el estado civil, la duración más corta de la enfermedad y un mejor estado mental pronosticaron un grado más alto de funcionamiento psicosocial. En comparación con el grupo de "cuidado de los cónyuges en dos intervalos", el puntaje de la GAF fue considerablemente más bajo en el grupo de "transición al cuidado de los padres". La presencia de cuidado familiar no fue un factor pronóstico importante de la intensidad de los síntomas ni del funcionamiento psicosocial en las personas con esquizofrenia. En resumen, en este estudio se muestran los efectos pronósticos a 21 años de la transición de los cuidadores familiares en el estado mental de las personas con esquizofrenia, pero no la presencia de cuidado familiar. Deben ofrecerse intervenciones psicosociales y orientación específica a los cuidadores familiares para mejorar su calidad de cuidado y mejorar el pronóstico de las personas con esquizofrenia durante los periodos prolongados de cuidado en el hogar.

RESUMEN

BACKGROUND: It remains unknown what the impacts of multiple dimensions of contact (e.g. level, quantity and quality) are on the stigma of mental illness. AIMS: To explore the relationship between the multiple dimensions of contact and stigma of mental illness among family members (FM), mental health workers (MHW) and community residents (CR) in Hong Kong. METHODS: The stigma, contact and knowledge were measured in FM, MHW and CR in Hong Kong. Multiple regression analyses were used. RESULTS: MHW (n = 141) had higher knowledge, more contact and lower stigma of mental illness than CR (n = 95) or FM (n = 62). Knowledge and contact quality were significantly associated with lower stigma of mental illness in the three groups. However, contact level and contact quantity were not significantly associated with most stigma components. The contact level was positively associated with stigma of mental illness among FM and CR. CONCLUSIONS: The results of this study highlight the differences in knowledge, contact and stigma of mental illness among different stakeholder groups. This study suggests that positive contact (e.g. equal, supportive, voluntary and pleasant contact) reduces stigma of mental illness, while negative contact (e.g. unfriendly, unsupportive, unpleasant contact) may increase stigma. The Enhancing Contact Model (ECM) should be tested in future anti-stigma interventions.

RESUMEN

BACKGROUND: It is unknown whether and how poverty influences the long-term outcome of persons with severe mental illness (SMI). AIMS: To explore the change of poverty status in persons with SMI from 1994 to 2015 and examine the impact of poverty status on patients' outcome in rural China. METHOD: Two mental health surveys using identical methods and International Classification of Disease (ICD-10) were conducted in 1994 and 2015 in the same six townships of Xinjin County, Chengdu, China. RESULTS: The annual net income per person was 19.8% and 100.2% higher for the general population than for persons with SMI in 1994 and 2015 respectively. Compared with 1994 (48.2%), persons with SMI in 2015 had significantly higher rates of poor family economic status (

RESUMEN

Current studies have shown that POTE ankyrin domain family members have high expressions as tumor antigens in malignant tumors, such as prostate cancer, ovarian cancer, breast cancer and the like. POTEE is a member of the POTE anchor protein family E. However, its role in colorectal carcinoma (CRC) has not been studied. In this study, the function of POTEE in CRC was examined for the first time and its correlation with CRC cell biological behaviors was analyzed. Quantitative reverse transcription-polymerase chain reaction (qRT-PCR), western blotting, and immunohistochemistry revealed that POTEE was remarkably overexpressed in CRC and associated with an aggressive phenotype. We also found that POTEE was localized in the cytoplasm. In addition, downregulation of POTEE expression can notably inhibit the proliferation, migration, and invasion of CRC cell in vitro, and repressed tumor growth and metastasis in vivo. In contrast, overexpression of POTEE could promote the aggressive behaviors of CRC cells. Mechanistically, POTEE promoted CRC migration, invasion and epithelial-mesenchymal transition (EMT) by increasing the activation of Rac1 and Cdc42. To summarize, these results suggested that POTEE might serve as an oncogene for CRC tumorigenesis and progression, and may become a novel molecular marker for clinical diagnosis and treatment.
