Background
The miR-129-5p has been reported to be aberrant expression and exert vital roles in tumor progression of various malignancies. However, the effects on EMT in gastric cancer and its precise molecular mechanism in gastric cancer remain unclear.Methods and materials
RT-qPCR was performed to evaluate the expression level of miR-129-5p and HMGB1 in cell lines. Cell proliferation was detected via CCK-8. The epithelial mesenchymal transition (EMT) related proteins and the expression of HMGB1 were detected by western blot analysis. Luciferase assays were used to validate binding seeds between miR-129-5p and HMGB1.Results
miR-129-5p was downregulated in gastric cancer cells compared with GES-1. At the same time EMT was promoted in gastric cancer cells compared to GES-1. Overexpression of miR-129-5p inhibited EMT and proliferation. MiR-129-5p negatively and directly targeted HMGB1. HMGB1 was upregulated in gastric cancer cells and HMGB1 knocked-down inhibited EMT and cell proliferation.Conclusion
Taken together, upregulation of miR-129-5p associated with gastric cancer proliferation and EMT, and serves as a potential diagnostic and therapeutic target via miR-129-5p/HMGB1 pathway in gastric cancer. 相似文献2.

Background
MiR-138-5p is regarded as a tumour suppressor in many cancers. Transforming growth factor beta (TGF-β) often acts as a tumor promotor at the late stages of human cancers. However, the function of miR-138-5p on lung adenocarcinoma cells induced by TGF-β remains to be further confirmed.Methods
RT-qPCR was used to detect the expression of human lung adenocarcinoma tissues, adjacent normal tissues, and relative cell lines. When the lung adenocarcinoma cells A549 and H1299 were transfected with negative control (NC), miR-138-5p mimics and miR-138-5p inhibitor by lipofectamine3000 and treated with or without TGF-β1, the lung adenocarcinoma cell function was detected by Immunofluorescence, Western blotting (WB), cell counting Kit-8 (CCK8), colony formation, EdU, Wound-healing and Transwell assays. The relation between miR-138-5p and zinc finger E-box-binding homeobox 2 (ZEB2) was detected by RT-qPCR, WB, and Luciferase reporter assays. When ZEB2 was knocked down, the lung adenocarcinoma cell function was detected by WB, CCK8 and Transwell assays.Results
The expression of miR-138-5p was decreased in lung adenocarcinoma tissues and cell lines. When treated with or without TGF-β1, overexpression of miR-138-5p suppressed EMT, proliferation and metastasis of A549 and H1299. ZEB2 was verified as the direct target of miR-138-5p. Downregulation of ZEB2 suppressed EMT, proliferation and metastasis of lung adenocarcinoma cell, which could be reversed by miR-138-5p inhibitor.Conclusions
MiR-138-5p inhibits epithelial-mesenchymal transition, growth and metastasis of lung adenocarcinoma cells through targeting ZEB2. 相似文献3.
Background
Endometrial carcinoma is one of the common carcinomas in the female reproductive system. It is reported that miR-204-5p is down-regulated in endometrial carcinoma. However, the mechanism and key pathways of miR-204-5p in endometrial carcinoma have not been clarified.Material/Methods
We evaluated the expression profiles and prognostic value of miR-204-5p expression in endometrial carcinoma by using bioinformatics analysis of a public dataset from TCGA. Drug of endometrial carcinoma from DrugBank, GO analysis, KEGG analysis, PPI network, mutation, as well as assessment of the prognostic significance were performed to the overlapping target genes of miR-204-5p in endometrial carcinoma. The relative expression levels of miR-204-5p target genes in endometrial carcinoma, including SF3B1, FBXW7, SPOP, and BRD4, were assessed by real-time quantitative polymerase chain reaction (RT-qPCR).Results
First, through DrugBank website, we obtained target drugs for endometrial carcinoma. MiR-204-5p expression was found to be lower in the endometrial carcinoma tissues than in adjacent normal tissues from TCGA. Next, we identified 143 genes as potential targets of miR-204-5p. Then, through GO enrichment analysis, KEGG signaling pathway and PPI analysis, we revealed the key networks in endometrial carcinoma. Next, mutation and assessment of the prognostic significance of endometrial carcinoma were obtained. At last, in endometrial carcinoma, the relative expression of SF3B1 and BRD4 increased, and the relative expression of FBXW7 decreased.Conclusions
MiR-204-5p is down-regulated in endometrial carcinoma and affects the prognostic significance of endometrial carcinoma, which might play an important role in the tumorigenesis of endometrial carcinoma. 相似文献4.

Objective
To determine the effect of encounter patient decision aids (PDAs) as evaluated in randomized controlled trials (RCTs) and conduct a narrative synthesis of non-randomized studies assessing feasibility, utility and their integration into clinical workflows.Methods
Databases were systematically searched for RCTs of encounter PDAs to enable the conduct of a meta-analysis. We used a framework analysis approach to conduct a narrative synthesis of non-randomized studies.Results
We included 23 RCTs and 30 non-randomized studies. Encounter PDAs significantly increased knowledge (SMD?=?0.42; 95% CI 0.30, 0.55), lowered decisional conflict (SMD= -0.33; 95% CI -0.56, -0.09), increased observational-based assessment of shared decision making (SMD?=?0.94; 95% CI 0.40, 1.48) and satisfaction with the decision-making process (OR?=?1.78; 95% CI 1.19, 2.66) without increasing visit durations (SMD= -0.06; 95% CI -0.29, 0.16). The narrative synthesis showed that encounter tools have high utility for patients and clinicians, yet important barriers to implementation exist (i.e. time constraints) at the clinical and organizational level.Conclusion
Encounter PDAs have a positive impact on patient-clinician collaboration, despite facing implementation barriers.Practical implications
The potential utility of encounter PDAs requires addressing the systemic and structural barriers that prevent adoption in clinical practice. 相似文献6.

Background
Gastric cancer (GC) is one of the most common cancers globally leading to 850,000 deaths each year. GC patients are often diagnosed at advanced stages which results in poor prognosis. This study aimed to identify a novel circulating miRNA as the diagnostic biomarker of GC and further explore its regulatory mechanisms in GC.Materials and methods
First, the candidate serum miRNA was selected after analysis of microarray data. Then, the levels of candidate miRNA in the serum of GC patients were validated in an independent cohort. The diagnostic utility of miRNA was evaluated by using receiver operating characteristic curve (ROC) analysis. The functional and pathways enrichment analysis of targets of candidate miRNA were explored by online tool DAVID.Results
After comprehensive analysis of Gene Expression Omnibus (GEO) dataset, miR-551b-5p was selected as candidate due to its highest differential fold-change. Another independent cohort showed that serum miR-551b-5p could differentiate GC patients from healthy controls (HCs) with area under the curve (AUC) of 0.84 (95%CI: 0.75-0.93). The functional and pathways enrichment analysis revealed that targets of miR-551b-5p mainly located in cytoplasm and significantly associated with regulation of ubiquitin-dependent protein catabolic process, cell division, and mRNA stability.Conclusions
Circulating miR-551b-5p was a novel promising biomarker for the detection of GC and exploration of the molecular mechanisms of miR-551b-5p is useful to search for new therapeutic strategies of GC. 相似文献7.

Introduction
Nearly sixty percent of patients with prostate cancer (PCa) undergo radiation therapy (RT). During the course of treatment patients may experience normal tissue reactions. It is a well established fact that genetic and epigenetic mechanisms, such as microRNA (miRNA) level changes might be associated with radiotoxicity, as a response to irradiation.Materials and methods
This is the first study that has investigated levels of radiosensory miRNAs in association with acute genitourinary radiotoxicity extracted from peripheral blood mononuclear cells (PBCs), in three points; before RT (BRT), after RT (ART) and on the first control examination (FCONT). We measured levels of miR-21/146a/155 expression by quantitative real-time PCR (qRT-PCR), comparative ΔΔCt method, in fifteen patients with localized prostate cancer, treated with three-dimensional conformal radiotherapy (3DCRT). Nine subjects have experienced acute genitourinary (GU) radiotoxicity whereas six where without GU radiotoxicity.Results
Firstly, we detected the highest levels of miR-21 in ART group (p?=?0.043) in the patients with acute GU radiotoxicity. Secondly, we found trend towards higher miR-21 levels and significantly higher levels of miR-146a/155 within the patients with acute GU toxicity than in patients without (p?=?0.068, p?=?0.016, and p?=?0.010, respectively). Thirdly, we detected significant change in miR-146a/155 levels within the patients without acute GU radiotoxicity during RT p?=?0.042, and p?=?0.041, respectively).Conclusion
miR-21/146a/155 might be useful potential factors of radiosensitivity and acute genitourinary radiotoxicity in prostate cancer patients. miRNA might have great potential as predictors of various pathological conditions extracted from PBMCs. 相似文献8.

Objective
To determine the effectiveness of an online video intervention in improving self-efficacy and eye drop application technique in glaucoma patients.Methods
We randomized ninety-two patients with primary open-angle glaucoma, all who self-administer their eye drops, to either watch the 4-minute Meducation® eye drop technique video in the intervention group, or a nutrition video in the control group. We assessed five eye drop technique steps using objective video recordings at baseline, immediately after watching the video, and 1 month later. We used linear regression models to determine whether the intervention group had better self-efficacy and technique than the control group.Results
Adjusted for baseline technique and other covariates, eye drop technique averaged 0.73 steps better in intervention patients than controls immediately after the video (p?=?0.003) and 0.63 steps better at 1 month (p?=?0.01). Adjusted for baseline self-efficacy, intervention patients had better eye drop technique self-efficacy than controls immediately after the video (p?=?0.02) and at 1 month (p?=?0.02).Conclusion
A short educational video can significantly improve glaucoma patients’ short-term self-efficacy and eye drop technique.Practice implications
Videos may provide an inexpensive, convenient way to deliver eye drop technique education in any provider’s office or online. 相似文献10.

Objective
To compare motivational interviewing (MI) with conventional care regarding the health-related quality-of-life (HRQoL) of adolescents with overweight/obesity.Methods
RCT with parallel design, involving two groups: intervention group (MI group [MIG]) and control group (conventional intervention group [CIG]). The intervention included three 30-minute interviews 3 months apart.Outcome
Change in Pediatric Quality of Life Inventory (PedsQL) scores. A mixed repeated-measures analysis of variance was used to assess group versus time interactions.Results
Eighty-three participants finished the protocol (82% girls). MIG participants showed a significant average increase (+4.7) on the Psychosocial (t[41] = -2.388, p = .022, d = .37) and Emotional Subscales (+5.1) (t[41] = 5.733, p < .001, d = .88). CIG participants showed a significant average decrease on the Psychosocial (-6.1) (t[40] = 5.733, p < .001, d = .90), Emotional (-14.1) (t[40] = 7.249, p < .001, d = 1.13) and Social Subscales (-3.8) (t[40] = 3.782, p = .001, d = .59) and on the Total Score (–4.4) (t[40] = 3.535, p = .001, d = .55)Conclusion
MI improved HRQoL among overweight adolescents participating in a weight management program.Practice implications
MI increases HRQoL and has the potential to benefit weight management programs for adolescents. 相似文献11.

Objective
Identify inhaler use characteristics among English (ESP) and non-English speaking patients (NSP) to develop quality improvement efforts.Methods
Outpatients were surveyed for technique confidence, education, preferences and disease control. We compared characteristics between ESP and NSP.Results
Of 197 respondents, 75% were ESP, 25% were NSP. Compared to NSP, ESP responders were more likely female (57% vs 31%, p?=?0.001), used inhalers for a longer time (10 vs 6 years, p?=?0.008) and had higher rates of metered dose inhaler use (85% vs. 60%, p?<?0.001). Both language groups had similar confidence in inhaler use, after adjustment for age, gender and duration of use. Similar rates of inhaler technique education were reported by ESP and NSP at the initial visit. More NSP reported receiving education at subsequent visits (54% vs. 72%, p?=?0.03). Education for both groups was mostly performed by a clinician. Both language groups reported low internet use for learning proper technique, low interest in a separate education session, preferred an active learning method.Conclusions
These findings will be used to further develop quality inhaler education efforts at our institution.Practical implications
Local patient preferences should be considered when designing inhaler education programs. 相似文献12.

Objective
To investigate role of β-catenin and lncRNA MALAT1/miR-217 axis to converge into the regulation of ZEB-1 in hepatocyte growth factor (HGF)-induced hepatocytes differentiated from bone marrow mesenchymal stem cells (BM-MSCs).Methods
BM-MSCs were isolated and HGF was used to induce the differentiation of BM-MSCs into hepatocytes. HSC-T6 cells, BRL-3?A cells and differentiated BM-MSCs were treated by lipopolysaccharide(LPS). shRNAs were used to silence β-catenin and recombinant plasmids were used to over-express ZEB1. Measurement of cell viability was conducted using MTT assay and Hoechst 33342 staining. RNA immunoprecipitation (RIP) assay was used to determine binding of miR-217-3p and MALAT1.Results
BM-MSCs successfully differentiated into hepatocytes by HGF treatment. Expression of β-catenin, ZEB-1 and TERT was up-regulated to a higher level in hepatocytes differentiated from BM-MSCs than HSC-T6 cells and BRL-3?A cells after LPS stimulation. When β-catenin was knocked down in all cell lines, expression of β-catenin, ZEB-1 and TERT was significantly decreased as well as telomerase activity. While when ZEB1 was over-expressed, expression of TERT and telomerase activity was all significantly up-regulated. In hepatocytes differentiated from BM-MSCs, miR-217 was down-regulated and lncRNA MALAT1 was up-regulated. RIP analysis showed MALAT1 was physically associated with miR-217 and might function in the regulation of ZEB-1, further enhancing the expression of TERT so as to augment telomerase activity.Conclusion
We successfully used HGF to mediate differentiation of BM-MSCs into hepatocytes, and found that β-catenin-coordinated MALAT1/miR-217 axis could up-regulate expression of ZEB-1 and further enhanced the telomerase activity through regulation of TERT in BM-MSCs differentiating into hepatocytes. 相似文献13.

Introduction
Syndecan-1 is heparan sulfate proteoglycans (HSPGs) that is used as coreceptors for signaling of growth factors. The comprehensive effect of syndecan-1 is to augment receptor stimulation at little ligand concentrations.The goal of this research
is to study syndecan-1 expression in breast carcinoma and its value in predicting the prognosis in comparison to other clinicopathological parameters.Material &methods
immunohistochemistry study for syndecan-1 is done on 103 cases of invasive breast carcinoma. Its expression is assessed and correlated to other clinicopathological parameters and prognosis.Results
overexpression was significantly related to high histologic grade (p?=?0.001), large tumor size (p?=?0.043), HER2-positive status (p?=?0.001), and ER&PR-negative status (p?=?0.001). It was also have a negative impact on the overall survival (p=0.012) and disease free survival (p?=?0.009). Syndecan-1 expression showed weak positive correlation with Her 2 expression (Correlation Coefficient (co): 0.332, p?=?0.001).Conclusion
syndecan-1 is a good predictor of poor overall survival and recurrence/ metastasis free survival. It is associated with aggressive phenotype as HER2 enriched and Triple negative rather than luminal subtypes of breast carcinoma. So it can be added to the hormonal receptors and HER 2 assay in the routine management of invasive breast cancer after confirmation on a more larger study. 相似文献14.
Objective
Patient education on high-risk medications such as warfarin is important, and they require quick follow-up after initiation to maximize efficacy and safety. In our Anticoagulation Clinic, two 60-minute new patient appointments are available each day, contributing to prolonged lead-time. We instituted standardized warfarin video education to shorten in-clinic-room visit time, to potentially increase new patient appointments.Methods
Patients viewed the video in the waiting area with a goal to decrease visit times by 15?min (25%), before pharmacists completed their visit. Data collected included time spent in the clinic room, education comprehension, and patient feedback.Results
Ninety patient visits were evaluated in one pre-intervention and two post-intervention phases. Patients who received video education spent less time in the clinic room versus those who had not (52.4 vs 39.4?min, p?=?0.001), and two-thirds of all post-intervention visits achieved 25% reduction in visit time. There were no significant differences in education comprehension and patient satisfaction.Conclusion
Video education significantly decreased in-clinic-room visit time, and most patients achieved a goal of 25% reduction in time spent, without a change in comprehension or patient satisfaction.Practice implications
Implementation of video education can reduce clinic times in many patients without significantly impacting patient satisfaction. 相似文献15.

Background
Insulin titration is typically done face-to-face with a clinician; however, this can be a burden for patients due to logistical issues associated with in-person clinical care. The Mobile Insulin Titration Intervention (MITI) used basic cell phone technology including text messages and phone calls to help patients with diabetes find their optimal basal insulin dose (OID).Objective
To evaluate sociodemographic and clinical correlates of reaching OID, text message response rate, and days needed to reach OID.Methods
Primary care providers referred patients to MITI and nurses delivered the program. Three multivariable regression models quantified relationships between various correlates and primary outcomes.Results
The sample included 113 patients from 2 ambulatory clinics, with a mean age of 50 years (SD?=?10), 45% female, 79% Hispanic, 43% unemployed, and 46% uninsured. In regression models, baseline fasting blood glucose (FBG) was negatively associated with odds of reaching OID and 100% text responses, and positively associated with days to reach OID, p?<?.05).Conclusions
Patients with higher baseline FBG levels were less successful across outcomes and may need additional supports in future mHealth diabetes programs.Practical Implications
Basic cell phone technology can be used to adjust patients’ insulin remotely, thereby reducing logistical barriers to care. 相似文献16.

Background
Studies have shown that 30–50% of non-small cell lung cancer (NSCLC) patients develop brain metastasis (BM). Since BM shortens overall survival and decreases the quality of life, early detection and treatment of BM are vital. While data are available for clinical risk factors of NSCLC with BM, histopathological factors are not well understood. Therefore, we evaluated the histopathological related factors which will help early detection and selection of effective treatment options.Materials and methods
A total of 117 surgical lung specimens diagnosed as NSCLC with BM were included as a study group. We included 237 cases without BM as a control group. One pathologist reviewed H&E slides and analyzed the histopathologic factors of all cases.Results
In pulmonary adenocarcinoma, vascular invasion, N stage, micropapillary pattern and necrosis were significantly associated with BM in multivariate analysis (vascular invasion, p?=?0.009; micropapillary pattern, p?=?0.024; others, p?<?0.001). Tumor with extensive necrosis had higher hazard ratio and shorter time to BM (p?<?0.001).Conclusion
Our findings suggest that necrosis is a new predictive factor of BM in pulmonary adenocarcinoma. Short term follow-up is needed especially when extensive necrosis is present. 相似文献17.

Objective
In a pilot RCT we assessed training a dietitian in “Healthy Conversation Skills” (HCS) to support behavior change. This study describes the acceptability of the intervention from the participant and practitioner perspective.Methods
Seventy pregnant women participated (intervention?=?33; control?=?37). The evaluation included: i)audio-recording sessions to assess use of HCS from the intervention dietitian; ii)semi-structured interview with the intervention dietitian to assess experiences of using HCS; iii)Quality of Prenatal Care Questionnaire and focus groups to assess participants’ views of study experience.Results
Intervention sessions involved conversations where the dietitian used HCS. The dietitian reflected on the simplicity of learning HCS in training but the challenges of embedding these new skills in practice and highlighted the need to review and reflect on practice as an ongoing process. Intervention participants were more satisfied with the study (p?=?0.05) and more likely to agree that the dietitian took time to ask about things that were important to them (p?=?0.04) than control participants.Conclusion
Use of HCS by practitioners is an acceptable way to support lifestyle changes in pregnancy.Practice implications
Use of HCS provide opportunities to support behaviour change. Review of and reflecting on practice may facilitate the application of new skills in practice. 相似文献19.
