Effects of Srxn1 on growth and Notch signalling of astrocyte induced by hydrogen peroxide.

Objective: To investigate the effect of Sulfiredoxin-1 (Srxn1) on astrocyte injury induced by hydrogen peroxide (HO).

Methods: Observing the changes of HO on contents of lactate dehydrogenase (LDH), malondialdehyde (MDA), superoxide dismutase (SOD) and apoptosis after transfected Srxn1 siRNA into astrocytes. The protein expression of Notch 1, NICD and Hes1, the content of LDH and MDA, the activity of SOD and apoptosis rate of astrocytes after inhibiting or activation of Notch signalling pathway were detected by Western blot, ELISA and flow cytometry, respectively.

The prognostic efficacy of the 8th edition UICC TNM classifications for gastric cancer in Chinese patients: A study based on follow-up system of nursing department.

This study aimed to analyze the applicability of the Union for International Cancer Control (UICC) tumor-node-metastasis (TNM) classification 8th edition for Chinese patients with gastric cancer.A review of all inpatient and outpatient records of patients with gastric cancer was conducted in the First Affiliated Hospital of China Medical University and Liaoning Cancer Hospital and Institute. All patients who met the inclusion criteria and were seen from January 1980 through December 2009 were included in the study.

Improvements to the gastric cancer tumor-node-metastasis staging system based on computer-aided unsupervised clustering.

Background: The Union for International Cancer Control (UICC) tumor-node-metastasis (TNM) classification is a key gastric cancer prognosis system. This study aimed to create a new TNM system to provide a reference for the clinical diagnosis and treatment of gastric cancer.

Methods: A review of gastric cancer patients' records was conducted in The First Hospital of China Medical University and the Liaoning Cancer Hospital and Institute.

A similarity measure method combining location feature for mammogram retrieval.

Background: Breast cancer, the most common malignancy among women, has a high mortality rate in clinical practice. Early detection, diagnosis and treatment can reduce the mortalities of breast cancer greatly. The method of mammogram retrieval can help doctors to find the early breast lesions effectively and determine a reasonable feature set for image similarity measure.

Predicting level 2 axillary lymph node metastasis in a Chinese breast cancer population post-neoadjuvant chemotherapy: development and assessment of a new predictive nomogram.

Background: We aimed to develop a new nomogram to predict the probability of level 2 axillary lymph node metastasis (L-2-ALNM) in breast cancer (BC) patients treated with neoadjuvant chemotherapy (NAC).

Methods: Data were collected from 709 patients who received neoadjuvant chemotherapy and then underwent axillary lymph node (ALN) dissection between May 2009 and December 2015 at the Liaoning Cancer Hospital. The level 2 axillary lymph node metastasis (L-2-ALNM ) nomogram was created from the logistic regression model.

Overexpression of let-7a increases neurotoxicity in a PC12 cell model of Alzheimer's disease via regulating autophagy.

Increased deposition of β-amyloid (Aβ) protein is one of the typical characteristics of Alzheimer's disease (AD). Recent evidence has demonstrated that the microRNA let-7 family, which is highly expressed in the central nervous system, participates in the regulation of pathologic processes of AD. In the present study, the effect of let-7a overexpression on Aβ1-40-induced neurotoxicity was evaluated in PC12 and SK-N-SH cells.

Prognostic significance of GSTP1 in patients with triple negative breast cancer.

Background: Previous studies showed that glutathione S-transferase Pi 1 (GSTP1) is a critical metabolic driver that is heightened specifically in triple negative breast cancer (TNBC) and drives breast cancer pathogenicity. This study focuses on investigating the relationship between the expression of the GSTP1 protein and TNBC metastasis and prognosis in China.

Results: Chi-square and Fisher's exact tests showed that tumor size (P=0.

Prognostic significance of subclassification of stage IIB lung cancer: a retrospective study of 226 patients.

We investigated the prognostic significance of subclassification of stage IIB lung cancer according to the eighth tumor-node-metastasis (TNM) classification. To this purpose, the prognostic outcomes of 226 stage IIB lung cancer patients who underwent surgery without adjuvant therapies between 2001 and 2010 were evaluated retrospectively based on the eighth TNM classification. Of the 226 patients, 23, 30, 118 and 55 had pT1b, pT1c, pT2a, and pT2b stage cancers, respectively.

The prognostic efficacy and improvements of the 7th edition Union for International Cancer Control tumor-node-metastasis classifications for Chinese patients with gastric cancer: Results based on a retrospective three-decade population study.

This study aimed to evaluate survival trends for patients with gastric cancer in northeast China in the most recent three decades and analyze the applicability of the UICC tumor-node-metastasis (TNM) classification 7th edition for Chinese patients with gastric cancer. A review of all inpatient and outpatient records of patients with gastric cancer was conducted in the first hospital of China Medical University and the Liaoning Cancer Hospital and Institute. All patients who met the inclusion criteria and were seen from January 1980 through December 2009 were included in the study.

EZH2 mediates ATO-induced apoptosis in acute myeloid leukemia cell lines through the Wnt signaling pathway.

In this study, we examined the mechanisms associated with EZH2 mediation of apoptosis and chemoresistance to arsenic trioxide (ATO) in acute myeloid leukemia (AML) cell lines through the Wnt/β-catenin signaling pathway. The induction of spontaneous apoptosis observed in multiple EZH2-silenced leukemic cell lines was assessed by flow cytometry, and levels of Wnt/β-catenin-related expression were determined by western blot analysis. In comparison with AML control cells, EZH2-knockdown cells exhibited increased apoptosis and significant downregulation of β-catenin expression, as well as decreases in GSK-3β phosphorylation and β-catenin activation (p < 0.

Galectin-3 as a marker and potential therapeutic target in breast cancer.

Galectin-3 has a relatively high level of expression in triple-negative breast cancers and is a potential marker for this disease. However, the clinical and prognostic implications of galectin-3 expression in breast cancer remain unclear. We examined mastectomy specimens from 1086 breast cancer cases and matching, adjacent non-cancerous tissues using immunohistochemistry.

Gross total resection of glioma with the intraoperative fluorescence-guidance of fluorescein sodium.

Objective: High dose fluorescein sodium has been utilized for fluorescence-guided tumor resection with conflicting reports on the efficacy of this procedure. The aim of this study was to reevaluate the utility and clinical limitations of using fluorescein sodium for the treatment and resection of glioma brain tumors.

Methods: Patients diagnosed with glioma were divided into two groups with a total of 22 patients enrolled in the study: 1) the study group (n=10), patients that received intravenous injection of fluorescein sodium and 2) the control group (n=12), patients that did not receive injections during surgical resection.
