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2.

Purpose
To screen novel candidate biomarkers in primary colorectal cancer (CRC), and indentify their clinical valuation in progress of colorectal cancer.Methods
By using antibody microarray, 274 target proteins in tissue samples from primary colorectal cancer patients were detected. Among differently expressed proteins in CRC tissues, As promising candidate biomarker, RANTES/CCL5 was validated by enzyme-linked immunosorbentassay and immunohistochemistry (IHC), and the clinical significance of CCL5 was analyzed.Results
Totally, 25 differentially expressed proteins were indentified between colorectal cancers and matched normal mucosa. CCL5 expression was significantly associated with adverse pathological progress, apt to lymph node metastasis and higher T stage.Conclusions
CCL5 may contribute to promoting tumor growth, and CCL5 is a promising target that may help in understanding the pathogenesis of CRC. 相似文献3.

Background
MicroRNAs (miRNAs) are single-stranded, endogenous, non-coding RNAs that are increased or decreased in almost all cancer types, and they paly crucial roles in the tumorigenesis as well as development.Materials and methods
90 patients diagnosed with bladder cancer were enrolled in the present study. The bladder cancer tissues or adjacent normal tissues were obtained from the tumor area or adjacent normal zone. The expression level of miR-133b was examined by quantitative real-time polymerase chain reaction assay (qRT-PCR). Survival curves were displayed by the Kaplan-Meier method, and differences between two survival curves were calculated by the log-rank test.Results
The expression levels of miR-133b in bladder tissues were significantly decreased when compared with the matched adjacent normal bladder tissues (P?<?0.05). Moreover, miR-133b expression levels are significantly associated with lymphatic invasion (P?=?0.026), distant metastasis (P?=?0.025), tumor grade (P?=?0.038), as well as the muscle invasion status (P?<?0.001). The log-rank test indicated that patients with decreased miR-133b expression underwent poorer overall survival (P?=?0.007). Furthermore, multivariate Cox regression analysis showed that the expression level of miR-133b (P?=?0.024) was an independent factor for predicting the overall survival in patients with bladder cancer.Conclusions
The present study showed that miR-133b might be associated with bladder cancer progression, and its down-regulation might be a biomarker for poor prognosis of bladder cancer. 相似文献4.

Objectives
To figure out that if there is a consistency relationship of the BRAFV600E mutation in matched-lymph node metastasis and original papillary thyroid carcinoma (PTC) specimen for the same patient.Methods
We collected the specimen of thyroids and matched-lymph node metastases of PTCs and tested the BRAFV600E mutation status with amplification refractory mutation system (ARMS) PCR.Results
20 patients with PTC and metastasis lymph node were hired. In this cohort, 16 (80%) patients had the same BRAF genetic mutation status in thyroid and metastasis, and the other 4 (20%) had an inconsistent situation.Conclusions
Within our cohort, the data suggested that wild-type BRAFV600E oncogene in thyroid primary tumor does not rule out its mutation in lymph node metastasis, and vice versa. 相似文献5.

Introduction
The expression of bone morphogenetic protein-10 (BMP-10) is downregulated in some cancer types, but its function and mechanism in ovarian cancer remains unclear.Materials and methods
BMP-10 expression was detected in ovarian cancer tissues and cell lines by using immunochemistry and western blotting. Prognostic value of BMP-10 was evaluated by Kaplan-Meier curve and Cox regression model. Knockdown or overexpression of BMP-10 was conducted by using specific siRNA or pcDNA-BMP-10 in ovarian cancer cell lines. The biological features induced by BMP-10 were observed by MTT assay, wound-healing and transwell assays.Results
BMP-10 expression in ovarian cancer tissues was significantly lower than that in ovarian tissues. Low BMP-10 expression in ovarian cancer tissues was related to advance FIGO stage, higher histologic grade, lymph node metastasis, and peritoneal fluid. Kaplan-Meier analysis revealed that low BMP-10 expression was significantly associated with poor prognosis of patients with ovarian cancer. BMP-10 overexpression or knockdown significantly inhibited or promoted proliferation, migration, and invasion of ovarian cancer cells, respectively. Moreover, administration of neutralizing antibody or human recombinant BMP-10 would reverse these effects on ovarian cancer cells.Conclusion
Low BMP-10 expression was associated with poor prognosis and progression of ovarian cancer. 相似文献6.

Objective
To investigate the relation between donor characteristics and TRALI incidence.Background
Transfusion-related acute lung injury (TRALI) is a potentially fatal complication of transfusion. In pre-clinical studies and several clinical studies, TRALI has been related to loss of product quality during red blood cell (RBC) storage, called the “storage lesion”. Donor characteristics, as for example age, genetics and life style choices influence this “storage lesion”. We hypothesized that donor sex, age and blood type is related to TRALI incidence.Methods/materials
We performed a secondary analysis of two cohort studies, designed to identify TRALI risk factors by matching TRALI patients to transfused controls. We obtained donor sex, age and blood type from the Dutch Blood Bank Sanquin and investigated TRALI incidence in patients who were exposed to a certain donor characteristic. We used Kruskal-Wallis testing to compare the number of transfused products and Chi2 testing to compare proportions of TRALI patients and transfused control.Results
After implementation of the male-donor only plasma strategy, patients received more transfusion products from male donors. However, we did not detect a relation between TRALI incidence and donor sex. Both TRALI patients and transfused controls received mainly products from donors over 41 years old, but donor age did not influence TRALI risk. Donor blood type, the transfusion of blood type-compatible and blood type-matched products also had no influence on TRALI incidence.Conclusion
We conclude that in two cohorts of TRALI patients, donor age, donor sex and donor blood type are unrelated to TRALI. 相似文献7.

Objective
To assess the feasibility of a team-based prognosis and treatment goal discussion for women living with advanced breast cancer.Methods
Female patients diagnosed with advanced breast cancer (n?=?25) participated in a mixed methods study that evaluated the feasibility and effects of a planned and structured prognosis discussion. Audio analysis of the intervention appointments was conducted to assess intervention feasibility. Patient self-reports of prognosis related beliefs and treatment preferences were compared across intervention and usual care groups.Results
Most patients found the T-PAT appointment challenging but worthwhile. Intervention uptake by clinicians was good, but some fidelity disruptions were noted. T-PAT participants were more likely to hold realistic beliefs about disease curability after the appointment.Conclusion
Productive prognosis discussions can be delivered effectively by a practice-based clinical team within a semi-structured patient education appointment. It was perceived by patients with advanced breast cancer as both valuable and acceptable. T-PAT clinicians found the intervention easy to deliver.Practice implications
Regular implementation of T-PAT may help clinicians’ build prognosis discussion communication skills. T-PAT documentation provides valuable information that can be used to tailor ongoing care. 相似文献8.

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9.

Objectives
To explore healthcare professional perceived barriers and facilitators to discussing sexual health and wellbeing with patients after diagnosis of chronic illness.Methods
Five databases were searched and included data were synthesised using a meta-ethnographic approach. Confidence in findings was assessed using the GRADE-CERQual framework. Searches, extraction and quality assessment procedures were conducted independently by at least two authors.Results
Concepts extracted from 30 included studies were used to develop a conceptual framework based on five overarching themes. These were [1] individual and societal attitudes to sex and sexual wellbeing [2], patient specific factors [3], organizational and professional factors [4], strategies to overcome barriers in practice and [5] perceived training needs. Healthcare professionals acknowledged the importance of discussing and providing support for sexual wellbeing needs, but recognized it is not routinely provided.Conclusions
While patient specific factors and organizational issues such as lack of time were frequently identified as barriers, intra-personal and social perceptions appear to have the strongest influence on healthcare professional perspectives.Practice implications
Brief education and tools to support healthcare professionals to have effective conversations with patients are required. These should address social barriers, normalise sexual issues, and support healthcare professionals to initiate discussions around sexual concerns. 相似文献11.
Background
Numerous studies have demonstrated that aberrant microRNAs (miRNAs) are involved in tumorigenesis and tumor progression. Nevertheless, the precise role of miR-1-5p in gallbladder carcinoma cell growth and metastasis remains not fully revealed.Material and methods
The levels of miR-1-5p were detected in gallbladder carcinoma tissues and cell lines using qRT-PCR method. A series of functional assays, including cell proliferation, colony formation, wound healing and Transwell invasion were conducted using miR-1-5p or miR-1-5p inhibitor transfected cells.Results
MiR-1-5p was remarkably down-regulated in gallbladder carcinoma tissues and cell lines compared to normal. In addition, over-expression of miR-1-5p markedly suppressed the growth, migration and invasion of gallbladder carcinoma cell. Conversely, down-expression of miR-1-5p facilitated gallbladder carcinoma cell proliferation and aggressiveness. Mechanistic investigations demonstrated that neurogenic locus notch homolog protein 2 (Notch2) was the directly target of miR-1-5p and Notch2 mediated the inhibitory effect of miR-1-5p in gallbladder carcinoma cell growth and aggressiveness.Conclusion
Our findings demonstrated that miR-1-5p acted as a suppressive miRNA and played vital roles in the growth, migration and invasion of gallbladder carcinoma cell through targeting Notch2. 相似文献12.

Background
Previous studies indicated that miR-218 was deregulated in gastric cancer patients and correlated with tumor invasion and prognosis. The aim of this study was to clarify the effect of miR-218 on the malignant behavior of gastric cancer and its role in regulating Bmi-1/Akt signaling pathway.Materials and methods
We used miR-218 mimic to transfect gastric cancer cell lines AGS and SGC-7901, and the overexpression efficiency was validated using qRT-PCR assay. MTT assay and Transwell chamber system were performed to detect the effect of miR-218 on cell proliferation, invasion and migration on gastric cancer. Western blot and qRT-PCR assay was used to test the role of miR-218 in regulating Bmi-1/Akt signaling pathway.Results
As shown in our research, ectopic expression of miR-218 in gastric cancer cells inhibits the proliferation, invasion and migration of gastric cancer cells. In addition, miR-218 re-expression inhibits the expression of Bmi-1 and its downstream target p-Akt473, as well as MMPs and EMT process.Conclusions
miR-218 inhibits the proliferation, invasion and migration of gastric cancer cells through modulating EMT process and the expression of MMPs via Bmi-1/Akt signaling pathway. 相似文献13.

Objective
There is limited number of studies from Arabic countries on the participation of family members in Treatment decision-making (TDM) process. The aim of this study is to evaluate the role of family members in the TDM process among adult Omani women diagnosed with breast cancer.Methods
A cross-sectional study has been conducted with women diagnosed with breast cancer and their nominated family members.Results
A total of 79 patients and their nominated family members participated. The family members who were most engaged in the TDM were more likely to be young, male, employed and first-degree relative. The following characteristics of patients associated with more family-controlled the TDM: being older (crude odds ratio [OR]?=?7.71; 95% confidence interval [CI]: 2.28–22.20), no formal education (OR?=?0.18; 95% CI: 0.54) and diagnosed at stage IV (OR?=?6.55; 95% CI: 1.89–22.65). The family members who dominate communication with the oncologists were more likely to control the TDM (OR?=?6.03; 95% CI: 1.78–20.42).Conclusion
Several factors influence the TDM process including age, gender, employments status, educational level and capability of communication.Practice implications
The TDM process is heavily involves family members. This should be taking in consideration by oncologists during counselling in order to reach the best treatment. 相似文献14.

Background
Ficolin-3 is a pattern-recognition molecule with the ability to activate the lectin pathway of complement. It is found in lung, liver and blood, but its physiological role is unclear. We have investigated interaction of recombinant ficolin-3 with malignant cells and tissues.Material and Methods
Cells of various lines of human origin as well as ovarian tissue sections have been studied with the use of flow cytometry and immunohistochemistry.Results
Recombinant (but not serum-derived) ficolin-3 was found to bind strongly to the ovarian cancer cell lines, SKOV-3, OVCAR-3 and ES-2, at concentrations of 2.5?μg/ml and above. Moreover, His-tagged recombinant ficolin-3 (10?μg/ml) preferentially stained ovarian tissue sections from patients with malignant tumours compared with those from patients without. Binding to cell lines was inhibited by EDTA and specific carbohydrate ligands, indicating involvement of the fibrinogen-like domain. Binding was enhanced under mildly acidic conditions and at physiological pH after pre-incubation of cells with mildly acidic buffer.Conclusion
Basing on data concerning recombinant protein, it may be suggested that ficolin-3 is involved in immune response in ovarian cancer. However, unidentified serum factor(s) seem(s) to protect cancer cells from recognition by natural or rficolin-3. 相似文献15.
Objectives
To investigate the effects of various diets on structure and function of the bladder in both normal and obstructed bladders of male Wistar rats.Methods
Sham-operated rats and rats with experimentally-induced bladder outlet obstruction (BOO) were fed with standard rats’ feed (control), High-carbohydrate (HCD), High-fat (HFD) and High-protein (HPD) diets. Feeding was continued for 4 weeks after BOO surgery. Bladder weight, detrusor contractility, Rho-Kinase (ROK) and Myosin Light Chain Kinase (MLCK) expressions were determined using standard methods.Results
In comparison with control, bladder weight was increased in HFD (164?±?9?mg), BOO (437?±?21?mg), HFD-BOO (523?±?19?mg) and HPD-BOO (268?±?18?mg). Detrusor contractility was reduced in BOO and HFD-BOO. The ROK- I and II expressions were high in HCD-BOO and low in HPD-BOO but ROK-I was also elevated in BOO. However, MLCK increased only in HCD-BOO.Conclusion
The results of the study reveal that diets with varying macronutrient compositions have variable effects on the bladder with and without obstruction. High-fat diets especially, affect detrusor morphology and function in both obstructed and unobstructed bladders. 相似文献16.

Background
Constitutive activation of STAT3 have been shown in several tumor types including breast cancer. We investigate STAT3 expresion as possible molecular marker for breast cancer early detection, as well as prognostic factor for determination of tumor agressiveness.Methods
In this study we measure p(Y705)STAT3 expression in tumor and adjacent tissue of breast cancer patients by Western blot. For relapse-free survival (RFS) and overall survival (OS) we used Log-Rank test.Results
We show that average expression of p (Y705) STAT3 in tumor tissue is higher compared to adjacent tissue. Moreover, we found that patients with HER2 positive receptors had significantly higher pSTAT3 expression compared to HER2 negative patients. We showed that patients with high mammographic density had significantly higher tumor expression of pSTAT3 compared to patients with low mammographic density. Also, we show that pSTAT3 expression correlates with longer RFS in the entire group of patients, as well as in the group of ER positive, in lymph node positive and in older group of breast cancer patients (with age over 50). Furthermore, in the entire group of patients, in ER positive, in lymph node positive and in older group of patient, high expression of pSTAT3 showed a better survival than low expression of pSTAT3.Conclusion
Considering that the expression of pSTAT3 is associated with longer RFS and survival, it can be used as prognostic tools for determination of group of breast cancer patients with low-risk. 相似文献17.

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18.

Objective
To better understand decision role preferences in women diagnosed with breast cancer at a young age for return of results of genome sequencing in research and clinical settings.Methods
Participants were surveyed about communication and decision-making preferences related to genome sequencing results and factors that may affect these preferences. The primary outcome was decision role preference (Control Preference Scale) for selecting what results to receive within medical care or within a research study.Results
For results returned as part of medical care, most patients preferred a collaborative (N?=?481, 45%) or active (N?=?488, 45%) role with only 107 (10%) choosing a passive role. When making the decision as part of a research study, most patients preferred an active role (N?=?617, 57%), 350 (33%) choosing a collaborative role, and110 (10%) choosing a passive role.Conclusion
Most women in this study preferred to share in decision making. Participants had somewhat different role preferences for clinical and research contexts, with greater preference for active roles in the research context.Practice Implications
We advocate for practice guidelines that incorporate discussion of decision role as an integral part of patient centered care and shared decision-making and recognize that more work is needed to inform guidelines. 相似文献19.

Background
Increased body fat may be associated with an increased risk of developing an underlying pro-inflammatory state, thus leading to greater risk of developing certain chronic conditions. Immunoglobulin G has the ability to exert both anti- and pro-inflammatory effects, and the N-glycosylation of the fragment crystallisable portion is involved in mediating this process. Body mass index, a rudimentary yet gold standard indication for body fat, has been shown to be associated with agalactosylated immunoglobulin G N-glycans.Aim
We aimed to determine the association between increased body fat and the immunoglobulin G glycosylation features, comparing body mass index to other measures of body fat distribution.Methods
We investigated a sample of 637 community-based 45–69?year olds, with mixed phenotypes, residing in Busselton, Western Australia. Body mass index and the waist-to-hip and waist-to-height ratios were calculated using anthropometry, while dual-energy x-ray absorptiometry was performed to gain an accurate measure of total and area specific body fat. Serum immunoglobulin GN-glycans were analysed by ultra-performance liquid chromatography.Results
Twenty-two N-glycan peaks were found to be associated with at least one of the fat measures. While the previous association of body mass index to agalactosylated immunoglobulin G was replicated, measures of central adiposity explained the most variation in the immunoglobulin G glycome.Conclusion
Central adiposity is associated with an increased pro-inflammatory fraction of immunoglobulin G, suggesting that the android/gynoid ratio or waist-to-height ratio instead be considered when controlling for adiposity in immunoglobulin G glycome biomarker studies. 相似文献20.
