RESUMO
Acute myeloid leukemia (AML) is challenging to treat due to its heterogeneity, prompting a deep understanding of its pathogenesis mechanisms, diagnosis, and treatment. Here, we found reduced expression and acetylation levels of WISP2 in bone marrow mononuclear cells from AML patients and that AML patients with lower WISP2 expression tended to have reduced survival. At the functional level, overexpression of WISP2 in leukemia cells (HL-60 and Kasumi-1) suppressed cell proliferation, induced cell apoptosis, and exerted antileukemic effects in an in vivo model of AML. Our mechanistic investigation demonstrated that WISP2 deacetylation was regulated by the deacetylase histone deacetylase (HDAC)3. In addition, we determined that crosstalk between acetylation and ubiquitination was involved in the modulation of WISP2 expression in AML. Deacetylation of WISP2 decreased the stability of the WISP2 protein by boosting its ubiquitination mediated by NEDD4 and proteasomal degradation. Moreover, pan-HDAC inhibitors (valproic acid and trichostatin A) and an HDAC3-specific inhibitor (RGFP966) induced WISP2 acetylation at lysine K6 and prevented WISP2 degradation. This regulation led to inhibition of proliferation and induction of apoptosis in AML cells. In summary, our study revealed that WISP2 contributes to tumor suppression in AML, which provided an experimental framework for WISP2 as a candidate for gene therapy of AML.

BACKGROUND: the mortality associated with severe malaria due to Plasmodiun falciparum remains high despite improvements in malaria management. Case prensentation: this case series aims to describe the efficacy and safety of the exchange transfusion combined with artesunate (ET-AS) regimen in severe P. falciparum malaria. Eight patients diagnosed with severe P. falciparum malaria were included. All patients underwent ET using the COBE Spectra system. The aimed for a post-exchange hematocrit of 30%. Half the estimated blood volume was removed and replaced using fresh frozen plasma. The regimen was well-tolerated without complications. The parasite clearance time ranged from 1 ~ 5 days. Five patients with cerebral malaria exhibited full improved consciousness within 3 days, while patient2 with hemolysis improved on day 2. Liver function improved within 1 ~ 6 days, and patient 1 and patient 6 showed improvements renal function on days 18 and 19, respectively. The length of intensive care unit stay range from 2 ~ 10 days, and all patients treated with ET-AS remained in the hospital for 3 ~ 19 days. CONCLUSIONS: these preliminary results suggest that ET-AS regimens are a safe and effective therapy for severe P. falciparum malaria and can benefit patients in clinical settings.

The stress of disability significantly impacts an individual's quality of life and that of a spouse. Health empowerment, based on the idea that individuals may be successful despite disability, may be meaningful to disabled persons and their spouse carers. This cross-sectional survey study aimed to explore the effect of health empowerment on the health-related quality of life (HRQOL) of older individuals with disabilities and their spouse carers on both a personal (actor effect) and interpersonal level (partner effect). A total of 1092 dyads of older individuals with disabilities and their spouse carers residing in communities were recruited from seven provinces in China. Two separate Actor-Partner Interdependence Model analyses were conducted to examine the impact of health empowerment on the two domains of HRQOL: the Physical Component Score (PCS) and the Mental Component Score (MCS). The results revealed that health empowerment had actor effects on the PCS and MCS of older individuals with disabilities, as well as on the PCS and MCS of their spouse carers. However, no significant partner effects of health empowerment on the PCS and MCS of either the individuals with disabilities or their spouse caregivers were observed. Empowering individuals with disabilities and their spouse carers may help them enhance their own HRQOL, both physically and mentally. However, more research is required to determine the interpersonal effect of health empowerment on the HRQOL.

BACKGROUND: Although the therapeutic effect of antineoplastic drugs is incontestable, these agents can also potentially act as carcinogens, mutagens and/or teratogens in people. The aim of this study was to assess the effect of occupational exposure to antineoplastic drugs on DNA damage, assessed by the comet assay and cytokinesis-block micronucleus (CBMN) assay, in nurses. METHODS: The cross-sectional study enrolled 305 nursing staff members from 7 public hospitals in Shenzhen who handled antineoplastic drugs, and 150 healthy nursing staff members who were not exposed to antineoplastic drugs as the control group. DNA damage was assessed by the comet and CBMN assay. Multiple linear regressions and logistic regressions models were used to analyse the effect of occupational exposure to antineoplastic drugs on DNA damage. RESULTS: After adjustment for confounding factors, compared with non-exposure to antineoplastic drugs, exposure to antineoplastic drugs was positively related to tail moment, olive moment, tail length and tail DNA per cent, and adjusted ß or OR (95% CI) was 0.17 (0.08 to 0.26), 0.18 (0.10 to 0.27), 1.03 (0.47 to 1.60) and 1.16 (1.04 to 1.29) (all p<0.05). Moreover, similar significant relationships were observed for the biomarkers of the CBMN assay. Additionally, other than age, there was no interaction between antineoplastic drug exposure and other variables for the levels of biomarkers of the CBMN assay and the comet assay. CONCLUSIONS: The present results showed that exposure to antineoplastic drugs was positively related to the risk of DNA damage in nurses. The results imply that occupational exposure to antineoplastic agents is an important global public health problem that requires urgent attention.

BACKGROUND: Gynecological malignant patients often have significant psychological and physical problems. The feasibility and generalizability of traditional intervention method is low due to the high time and labor cost, large number of gynecological malignant tumor patients in China, as well as shortage of health professionals. Therefore, it is necessary to design an alternative, innovative, and easily accessible intervention method. This study aims to evaluate the effect of WeChat-based intervention on anxiety, depression and disease-related symptoms of patients with gynecological malignant tumors during rehabilitation. METHODS: A single-blinded, randomized, controlled, parallel-group pre-test and repeated post-test design will be conducted. A total of 76 participants will be randomly divided into the intervention group and control group. Anxiety and depression, disease-related symptoms, coping ability, benefit finding and quality of life will be measured at baseline and repeated immediately after the intervention (test 1), 3 months (test 2) and 6 months (test 3) after the intervention. DISCUSSION: As the first randomized controlled trial with rigorous research design for patients with gynecological malignant tumors in the rehabilitation stage in China, this study will provide evidences for the effectiveness of the WeChat platform during intervention of patients with gynecological malignant tumors in the rehabilitation stage. The results are helpful to further explore the effect of WeChat-based intervention on improving patients' anxiety and depression, disease-related symptoms, and quality of life.

OBJECTIVES: Previously published systematic reviews have explored the effects of therapeutic hypothermia on adult patients with traumatic brain injury (TBI). However, none explored the effect of early prophylactic hypothermia (within 6 h from injury to hypothermia induction). Animal studies indicated that early prophylactic hypothermia may reduce secondary injury and improve neurological outcomes. This systematic review aimed to investigate the effects of early prophylactic hypothermia on adult TBI regarding mortality, favourable outcomes, and complications. DATA SOURCE: We searched electronic databases including Cochrane CENTRAL, PubMed, MEDLINE, CINAHL, EMBASE, Web of Science, OpenGrey, and ClinicalTrials.gov from inception to June 12, 2019. Manual search was conducted for additional information. REVIEW METHODS: Only randomised controlled trials were included. The Cochrane Collaboration Risk of Bias Tool was used to assess the quality of included studies. We extracted general demographic characteristics, the initiation timing, methods of cooling, duration, target temperature, rewarming rate, mortality, neurological outcomes, and complications. RESULTS: Six studies with a total of 1207 participants were included. Meta-analyses showed no significant difference in mortality and favourable outcomes (risk ratio = 1.11, 95% confidence interval = 0.90-1.37, P = 0.32; risk ratio = 1.03, 95% confidence interval = 0.91-1.16, P = 0.65, respectively). Similar results were found regarding different durations of hypothermia and different rewarming rates. Various complications were reported in the included studies. No statistical difference was found in three studies, while complications were reported to be significantly higher in the hypothermia group in the other three studies. CONCLUSIONS: This review does not support the use of early prophylactic hypothermia (within 6 h after injury) as a neurological protection strategy in adult patients with TBI, irrespective of the short term or long term. No significant benefits were found regarding hypothermia with different rewarming rates. Owing to the limited number of studies, more randomised controlled trials with higher quality are required to establish true effects of early hypothermia in adult TBI.

PURPOSE: To investigate predictive risk factors for complications associated with migrating fish bones in the surrounding tissue of upper gastrointestinal tract. METHODS: A retrospective analysis over 12 years was conducted of 45 cases of buried fish bones in the surrounding tissue of upper gastrointestinal tract with complications. Meanwhile, a control group, including 39 cases of prolonged buried fish bones in the surrounding tissue of upper gastrointestinal tract without complications, was set. Patient clinical data were collected and analyzed to predict the risk factors for complications. RESULTS: The results of Chi-square test and univariate analysis both showed a significant difference in length of fish bone (> 2 cm), a history of concurrent medical illness (diabetes mellitus and renal hypofunction), symptoms (medium or heavy pain and dysphagia), and duration of significant symptoms (> 7 days) between the complication group and non-complication group. Multivariate analysis further identified length (> 2 cm), diabetes mellitus, medium or heavy pain, dysphagia, and duration of significant symptoms (> 7 days) as independent risk factors for complications. CONCLUSIONS: The consequences of fish bones migrating outside the upper gastrointestinal tract are various in different people. Awareness should be raised when encountering a patient ingesting a long fish bone, having a history of diabetes mellitus, presenting with significant discomforts, or these discomforts lasting for a long time. This study will help practitioners counsel their patients on the risks and `benefits of surgery versus observation of this condition.

BACKGROUND: The potential protective effects of dietary fiber against all-cause mortality, cardiovascular mortality, and cardiovascular disease in patients with chronic kidney disease have not been definitively established. To verify this relationship, a systematic review and a meta-analysis were undertaken. METHODS: PubMed, The Cochrane Library, Web of Science, Embase, ProQuest, and CINAHL were used to systematically search for prospective cohort studies that investigate the association between dietary fiber and all-cause mortality, cardiovascular mortality, and cardiovascular disease in individuals with chronic kidney disease (CKD). This search was conducted up to and including March 2023. RESULTS: The analysis included 10 cohort studies, with a total of 19,843 patients who were followed up for 1.5-10.1 y. The results indicated a significant negative correlation between dietary fiber and all-cause mortality among patients with CKD (HR 0.80, 95% CI 0.58-0.97, P < 0.001). Subgroup analysis further revealed that the study population and exposure factors were significantly associated with all-cause mortality (P < 0.001). Increased dietary fiber intake was associated with a reduced risk of cardiovascular mortality (HR 0.78; 95% CI 0.67-0.90) and a reduced incidence of cardiovascular disease (HR 0.87; 95% CI 0.80-0.95) among patients with CKD. CONCLUSIONS: The pooled results of our meta-analysis indicated an inverse association between dietary fiber intake and all-cause mortality, cardiovascular mortality, and cardiovascular disease.

PURPOSE: Immune thrombocytopenia (ITP) is an autoimmune disease characterized by accelerated platelet clearance. Gut dysbiosis was associated with its pathogenesis, but the underlying mechanisms have not been fully elucidated. Patients with ITP exhibit varying degrees of responsiveness to corticosteroid treatment. Therefore, prognostic indexes for corticosteroid responsiveness in ITP could offer valuable guidance for clinical practices. METHODS: The present study examined the signature of six types of gut-microbiota metabolites and forty-eight types of cytokines, chemokines, and growth factors and their clinical significance in patients with ITP. RESULTS: Both patients with good and poor corticosteroid responsiveness exhibited significantly elevated/suppressed secretion of twenty-two cyto(chemo)kins/growth factors in comparison to healthy controls. Additionally, patients with ITP demonstrated a significant decrease in plasma levels of trimethylamine-N-oxide (TMAO), which was found to be negatively correlated to circulating platelet counts, and positively correlated with Interleukin (IL)-1ß and IL-18. Notably, patients who exhibited poor response to corticosteroid treatment displayed elevated levels of TMAO and basic fibroblast growth factor (bFGF) in comparison to responders. Additionally, we found that the amalgamation of TMAO, bFGF and interleukin (IL)-13 could serve as a valuable prognostic tool for predicting CS responsiveness. CONCLUSION: Patients with ITP were characterized overall by an imbalanced secretion of cyto(cheo)kins/growth factors and inadequate levels of TMAO. The varying degrees of responsiveness to corticosteroid treatment can be attributed to different profiles of basic FGF and TMAO that might be related to overburdened oxidative stress and inflammasome overactivation, and ultimately mediate corticosteroid resistance.

Background: Antenatal depression is a commonly seen mental health concern for women. This study introduced a multicenter cross-sectional survey with a large sample to provide new insights into pregnant women's depression, its socio-demographic and obstetric characteristics correlates, and its perceived stress among Chinese pregnant women. Methods: This study conducted an observational survey according to the STROBE checklist. The multicenter cross-sectional survey was performed from August 2020 to January 2021 by distributing paper questionnaires among pregnant women from five tertiary hospitals in South China. The questionnaire included socio-demographic and obstetrics information, the Edinburgh Postnatal Depression Scale, and the 10-item Perceived Stress Scale. For the analyses, the Chi-square test and Multivariate logistic regression were utilized. Results: Among 2014 pregnant women in their second/third trimester, the prevalence of antenatal depression was 36.3%. 34.4% of pregnant women reported AD in their second trimester of pregnancy, and 36.9% suffered from AD in third trimester of pregnancy. A multivariate logistic regression model indicated that unemployed women, lower levels of education, poor marital relationships, poor parents-in-law relationships, concerns about contracting COVID-19, and higher perceived stress could aggravate antenatal depression among participants (p<0.05). Conclusion: There is a high proportion of antenatal depression among pregnant women in South China, so integrating depression screening into antenatal care services is worthwhile. Maternal and child health care providers need to evaluate pregnancy-related risk factors (perceived stress), socio-demographic factors (educational and professional status), and interpersonal risk factors (marital relations and relationship with Parents-in-law). In future research, the study also emphasized the importance of providing action and practical support to reduce the experience of antenatal depression among disadvantaged sub-groups of pregnant women.
RESUMO
Mesenchymal stem cells (MSCs) are multipotent cells traditionally derived from bone marrow (BM). They have been demonstrated to be widely applied in tissue regeneration and cellular therapy. As an alternative to BM, an umbilical cord (UC) is considered as a potential source of MSCs. Here, we showed that human UC-MSCs were easily isolated by a single enzymatic digestion and characteristic of plastic adherence and fibroblast-like morphology. UC-MSCs isolation was successful in 15 of 15 samples. The colony-forming unit-fibroblast frequency was obtained 54 ± 1.33 from 10³ UC-MSCs at passage 3, and the doubling time was (24.15 ± 0.49) h. Almost 10¹° UC-MSCs were largely produced in about 30 days. By flow cytometry analysis, the adherent cells displayed an abundant presence of CD73, CD90 and CD105 and absence of CD34, CD45 and HLA-DR. When cultured in differentiation media, they can be differentiated into adipocytes, osteocytes and chondrocytes. RT-PCR reactions confirmed that their multidifferentiation related genes were positive. Moreover, stem cell-related transcription factors Nanog, Oct-4 and Sox-2 were positively expressed in UC-MSCs. On the basis of these findings, the single enzyme method is a good method to obtain large-scale production of MSCs from whole human UC in a short time, and the UC can be considered as a novel and convenient source of adult MSCs displaying high expansion potential and primitive pluripotent stem cells.

BACKGROUND: Breast cancer-related lymphedema (BCRL) has a notable impact on patients' quality of life. However, no instrument is available to assess the problems in functioning due to BCRL in China. OBJECTIVE: The aims of this study were to translate and validate a Chinese version of the Lymphedema Functioning, Disability, and Health Questionnaire for Upper Limb Lymphedema (Lymph-ICF-UL). METHODS: A process of translation and cultural adaptation was conducted based on international standards. The study included 155 patients with BCRL and 90 patients without lymphedema. Psychometric properties that were tested consisted of internal consistency, test-rest reliability, content, construct and discriminant validity. RESULTS: The Cronbach's α was .92, and intraclass correlation coefficient was 0.83. Content validity was confirmed by a sufficient content validity index in item level and scale level. Exploratory factor analysis identified 5 factors accounting for 62.44% of the total variance, and confirmatory factor analysis fit indices were acceptable. Convergent validity was supported by a moderate correlation with the 36-item Short-Form Health Survey Questionnaire and relatively weak correlations with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30. There was good divergent validity with all hypotheses evaluating divergent validity were confirmed. Significant differences were found between the lymphedema and nonlymphedema groups. CONCLUSION: The Chinese version of the Lymph-ICF-UL is a valid and reliable instrument that can be used in both clinical and scientific settings in China. IMPLICATIONS: The Chinese version of the Lymph-ICF-UL could be applicable in assessing the impairments in function, activity limitations, and participation restrictions of Chinese patients with BCRL.

BACKGROUND: Sustained attention is a key variable affecting nursing students' academic performance during online learning process. However, factors contributing to sustained attention remain to be determined. AIMS: To analyze the path relationships among the influencing factors for nursing students' sustained attention in online learning using a structural equation model. DESIGN: A cross-sectional survey was administered. METHODS: Nursing students from 35 nursing schools in China were invited to participate in this survey study. Once participating in nursing programs and receiving online learning, they were eligible for the study. The data were collected online via the Questionnaire Star platform from March 29 to April 19, 2020. A structural equation modelling (SEM) approach was utilized to analyze the relationships between sustained attention and influencing factors (situational interest, anxiety, cognitive load, technology efficacy and professional identity). Furthermore, multi-group SEM analysis was conducted to examine whether the model equally fitted nursing students in different levels of programs. RESULTS: A total of 1089 nursing students completed the questionnaires. The majority (77.3%) were female and the mean age (SD) was 21.9 (4.4) years. A half (50.3%) were enrolled in the undergraduate programs. Results suggested that situational interest (ßâ¯=â¯0.19, 95% CI: 0.14, 0.24) and anxiety (ßâ¯=â¯-0.70, 95% CI: -0.76, -0.64) directly affected sustained attention. Both technology efficacy (ßâ¯=â¯0.22, 95% CI: 0.15, 0.28) and professional identity (ßâ¯=â¯0.20, 95% CI: 0.14, 0.26) had conferred indirect effects on sustained attention through academic emotions (i.e., situational interest and anxiety). The cognitive load directly affected sustained attention (ßâ¯=â¯-0.15, 95% CI: -0.20, -0.09) and indirectly affected sustained attention through anxiety (ßâ¯=â¯-0.32, 95% CI: -0.37, -0.26). There was no significant difference in the model fit among nursing students in various programs, including diplomatic, associate and bachelor's degree and above programs (∆χ2â¯=â¯27.228, pâ¯=â¯0.611). CONCLUSIONS: Technology efficacy, professional identity, situational interest, anxiety and cognitive load are identified as the main elements affecting nursing students' sustained attention. This model is equally suitable for nursing students in different levels of nursing programs. During the process of online learning, students' attributes, emotions and cognition should be considered to help students achieve learning goals in nursing education.

OBJECTIVE: The purpose of the study was to evaluate the efficiency of the supine roll test (SRT) and alternative positional tests (APTs) including the bow and lean test (BLT), pseudo-spontaneous nystagmus (PSN), and lying down nystagmus (LDN) to identify the affected side in horizontal canal benign paroxysmal positional vertigo (HC-BPPV). METHODS: In our prospective study, we performed a testing profile (PSN, BLT, LDN, SRT) on 59 HC-BPPV patients using videonystagmography. We compared the accuracy and sensitivity of these tests in HC-BPPV lateralization. Data from 30 healthy patients were collected as the control group. RESULTS: When performing positional tests, the elicited nystagmus coinciding with Ewald's second law was defined as a "positive response". In 44 patients with geotropic nystagmus, the rates of positive response in LDN, PSN, and BLT were 22/44 (50%), 19/44 (43%), and 18/44 (41%), respectively, while in 15 patients with apogeotropic nystagmus, the positive response rates of these three tests were 10/15 (66.7%), 9/15 (60%), and 4/15 (27.00%), respectively. The sensitivity of LDN (54.38%) was higher than that of PSN (47.37%) and BLT (38.60%) but lower than that of SRT (89.47%). Notably, the accuracy rate of PSN (71.8%) was higher than that of the other APTs. In 6 patients with symmetrical nysgtamus during the roll test, 5 patients showed a positive response in both LDN and BLT (83.34%), whereas 4 patients showed a positive response in PSN (66.67%). CONCLUSION: All positional tests are helpful for determining the affected side of HC-BPPV, but SRT carries the highest accuracy of lateralization followed by PSN.

Acute myeloid leukemia (AML) is a hematological malignancy with a low cure rate, especially in the elderly. Previous studies have shown that long non-coding RNA (lncRNA) may be an important factor in the pathogenesis of hematological malignancies, including acute myeloid leukemia (AML). However, the biological roles and clinical significances of most lncRNAs in AML are not fully understood. LncRNA CD27 Antisense RNA 1 (CD27-AS1), as a member of lncRNA family, has rare reports on its function. In present study, we found that the expression of CD27-AS1 examined by quantitative real-time PCR was markedly increased in the AML patients (N = 40) compared with healthy volunteers (N = 40). The overall survival time was significantly shorter in patients with higher CD27-AS1 expression than that in patients with lower CD27-AS1 (P < 0.01). Furthermore, downregulation of CD27-AS1 in AML cells suppressed proliferative ability, arrested cell cycle in G0/G1 phase, and induced apoptosis. However, CD27-AS1 overexpression further enhanced the malignant phenotype of AML cells. Additionally, CD27-AS1 was proved to increase PBX3 expression through sponging miR-224-5p. CD27-AS1 knockdown blocked the MAPK signaling through PBX3 silencing and further inhibited the cell growth of AML cells. Taken together, we demonstrate that CD27-AS1 may be a potential prognostic biomarker of AML, and our finding also provides a new insight for non-coding RNA-based therapeutic intervention of AML.

BACKGROUND: Sensory stimulation has been used in the early rehabilitation of comatose patients with traumatic brain injury, but the effect of sensory stimulation involving family members is unclear. OBJECTIVES: To evaluate the effects of family-centered sensory and affective stimulation on comatose patients with traumatic brain injury and explore the factors that affect the outcomes. DESIGN: A systematic review with a meta-analysis. DATA SOURCES: Electronic databases including PubMed, Web of Science, Google Scholar, Cochrane Library, CINAHL, China National Knowledge Infrastructure, and WanFang were searched from October 2019 to May 2020. REVIEW METHODS: Two reviewers independently assessed eligibility of potential studies and extracted data. Quality of included studies was assessed according to the evaluation criteria of Cochrane Evaluation Manual 5.1.0. Outcome measures of the meta-analysis were the Glasgow Coma Scale scores, the Western Neuro Sensory Stimulation Profile scores, awakening time, and satisfaction rate. To explore whether there was a difference in the effect between variants of the intervention, variables as subgroups were time to start intervention, type of intervention, duration of each intervention, daily frequency of intervention, days of intervention, and patient's area. RESULT: Seventeen randomized controlled trials were included in the review and meta-analysis. Most studies were of medium quality. The improvement of the Glasgow Coma Scale score is significantly greater with the intervention implemented within 24 h compared to the intervention implemented 24 h later (mean difference 3.91, 95% confidence interval 3.44-4.38 vs. mean difference 1.90, 95% confidence interval 1.69-2.12, respectively). The results of subgroup analyses show that auditory stimulation combined with tactile stimulation and multi-sensory stimulation are associated with better outcomes than a single use of auditory stimulation. Studies from Asia report more positive outcomes than those from America (mean difference 1.94, 95% confidence interval 1.73-2.16 vs. mean difference 0.44, 95% confidence interval -0.87-1.75). And the improvement of the Glasgow Coma Scale score with the stimulation performed by family members is greater than that with the stimulation implemented by nurses (mean difference 2.17, 95% confidence interval 1.67-2.66). Besides, it is associated with better awakening time, awakening rate, and satisfaction rate compared to routine care. CONCLUSION: Early family-centered sensory and affective stimulation is more effective than routine care and nurse-implemented sensory stimulation in improving the level of consciousness and cognition of comatose patients with traumatic brain injury, and multi-sensory stimulation is more effective than single stimulation. More studies with larger sample size and high quality in different countries are warranted.

Autophagy is an important mechanism involved in the regulation of acute myeloid leukemia (AML) chemoresistance. The long noncoding RNA (lncRNA) differentiation antagonizing non-protein coding RNA (DANCR) exhibits oncogenic activity in several types of human cancers, including AML, but it remains unclear whether it regulates autophagy and chemoresistance in AML. We report here that cytarabine (Ara-C) treatment elevates DANCR expression in human AML cells. In addition, DANCR overexpression confers and its knockdown diminishes Ara-C resistance in human AML cells, suggesting that DANCR positively regulates AML chemoresistance to Ara-C. Moreover, DANCR promotes autophagy in Ara-C-treated human AML cells and acts as a sponge to decrease miR-20a-5p expression, thereby upregulating the expression of ATG16L1, a critical component of the autophagy machinery. Importantly, ATG16L1 silencing abrogates DANCR-promoted autophagy and markedly restores DANCR-conferred Ara-C resistance, suggesting that DANCR promotes MIR-874-3P/ATG16L1 axis-regulated autophagy to confer Ara-C resistance in human AML cells. Together, this study identifies DANCR as a positive regulator of Ara-C resistance in human AML cells, suggesting this lncRNA as a potential target for overcoming Ara-C resistance in AML chemotherapy.

OBJECTIVES/HYPOTHESIS: To compare the efficacy and adverse effects of triamcinolone acetonide econazole cream and nystatin suspension in the treatment of otomycosis, and to determine the clinical features, predisposing factors, and etiology of otomycosis. STUDY DESIGN: A prospective study. METHODS: A prospective clinical trial was conducted on 786 patients diagnosed with otomycosis. The study population was randomly divided into two treatment groups of triamcinolone acetonide econazole cream (TAEC) and nystatin suspension in a 1:1 ratio. After clearing all fungal deposits in the external auditory canal, the antimycotic drugs were locally applied for at least 2 weeks. The efficacy and adverse effects were compared between the two antifungal reagents by statistical analysis. Meanwhile, patient clinical data were collected to find out the clinical features, predisposing factors, and etiology. RESULTS: Pruritis was the most common symptom and Aspergillus niger was the leading fungal pathogen. There was high association (44.5%) of otomycosis with a history of unclean ear picking. The cure rate was 97.6% in the TAEC group and 73.5% in the nystatin group (P < .01). Treatment with TAEC resulted in 2.4% of patients complaining of discomforts (irritant dermatitis, otalgia, or headache) versus 59.8% of patients complaining discomforts treated with nystatin (P < .01). The residue rate of antifungals was 1.9% in the TAEC group and 89.9% in the nystatin group (P < .01) at the end of treatment. CONCLUSIONS: Thoroughly cleaning of the external auditory canal followed by local use of TAEC under endotoscope is an effective, convenient, and well-tolerated treatment for otomycosis. LEVEL OF EVIDENCE: 1 Laryngoscope, 131:E1640-E1646, 2021.

PURPOSE: Arsenic combined with all-trans retinoic acid (ATRA) is the standard of care for adult acute promyelocytic leukemia (APL). However, the safety and effectiveness of this treatment in pediatric patients with APL have not been reported on the basis of larger sample sizes. METHODS: We conducted a multicenter trial at 38 hospitals in China. Patients with newly diagnosed APL were stratified into two risk groups according to baseline WBC count and FLT3-ITD mutation. ATRA plus arsenic trioxide or oral arsenic without chemotherapy were administered to the standard-risk group, whereas ATRA, arsenic trioxide, or oral arsenic plus reduced-dose anthracycline were administered to the high-risk group. Primary end points were event-free survival and overall survival at 2 years. RESULTS: We enrolled 193 patients with APL. After a median follow-up of 28.9 months, the 2-year overall survival rate was 99% (95% CI, 97 to 100) in the standard-risk group and 95% (95% CI, 90 to 100) in the high-risk group (P = .088). The 2-year event-free survival was 97% (95% CI, 93 to 100) in the standard-risk group and 90% (95% CI, 83 to 96) in the high-risk group (P = .252). The plasma levels of arsenic were significantly elevated after treatment, with a stable effective level ranging from 42.9 to 63.2 ng/mL during treatment. In addition, plasma, urine, hair, and nail arsenic levels rapidly decreased to normal 6 months after the end of treatment. CONCLUSION: Arsenic combined with ATRA is effective and safe in pediatric patients with APL, although long-term follow-up is still needed.

Targeting autophagy holds promise to enhance chemosensitivity in acute myeloid leukemia (AML). MicroRNA-143 (miR-143) has been found to suppress autophagy, however, it is not clear whether miR-143 augments cytarabine cytotoxicity in AML. Here, we report that cytarabine treatment reduces miR-143 expression in AML cell lines and primary AML cells. Moreover, ectopic expression of miR-143 further decreases cell viability in cytarabine-treated AML cells. By contrast, miR-143 knockdown inhibits cytarabine-induced cytotoxicity, together indicating a role of miR-143 in enhancing cytarabine sensitivity in AML. Subsequently, we show that miR-143 inhibits autophagy in cytarabine-treated AML cells by directly targeting autophagy-related proteins (ATG), ATG7 and ATG2B, two critical known components of autophagic machinery. More importantly, autophagy reconstructed via co-expression of ATG7 and ATG2B substantially attenuates miR-143-enhanced cytotoxicity, which is associated with suppression of caspase-dependent apoptotic pathway. Overall, this study demonstrates that targeting ATG7 and ATG2B-dependent autophagy is a critical mechanism by which miR-143 sensitizes AML to cytarabine, implicating it as a potential therapeutic target in AML treatment.
