Long non-coding RNA MIDEAS-AS1 inhibits growth and metastasis of triple-negative breast cancer via transcriptionally activating NCALD.

Background: Triple-negative breast cancer (TNBC) is a subtype of breast cancer with higher aggressiveness and poorer outcomes. Recently, long non-coding RNAs (lncRNAs) have become the crucial gene regulators in the progression of human cancers. However, the function and underlying mechanisms of lncRNAs in TNBC remains unclear.

Adaptive Model Predictive Control for Mobile Robots with Localization Fluctuation Estimation.

Mobile robots are widely employed in various fields to perform autonomous tasks. In dynamic scenarios, localization fluctuations are unavoidable and obvious. However, common controllers do not consider the impact of localization fluctuations, resulting in violent jittering or poor trajectory tracking of the mobile robot.

Decreased HMGB1 expression contributed to cutaneous toxicity caused by lapatinib.

The application of lapatinib, a widely used dual inhibitor of human epidermal growth factor receptor 1 (EGFR/ERBB1) and 2 (HER2/ERBB2), has been seriously limited due to cutaneous toxicity. However, the specific mechanism of lapatinib-induced cutaneous toxicity has not been clarified, leading to the lack of an effective strategy to improve clinical safety. Here, we found that lapatinib could induce mitochondrial dysfunction, lead to DNA damage and ultimately cause apoptosis of keratinocytes.

Evaluation of Carbon Nanoparticle Suspension and Methylene Blue Localization for Preoperative Localization of Nonpalpable Breast Lesions: A Comparative Study.

The resection of nonpalpable breast lesions (NPBLs) largely depends on the preoperative localization technology. Although several techniques have been used for the guidance of NPBL resection, more comfortable and effective methods are needed. This aim of this study was to evaluate the use and feasibility of carbon nanoparticle suspension (CNS) and methylene blue (MB)-guided resection of NPBL, to introduce alternative techniques.

Application of preoperative computed tomographic lymphography for precise sentinel lymph node biopsy in breast cancer patients.

Background: In light of the extensive application of sentinel lymph node biopsy (SLNB) in clinically node-negative breast cancer patients and the recently investigated failure of SLNB after lumpectomy, it has become important to explore methods for preoperative mapping of sentinel lymph nodes (SLNs) and their lymphatics to direct precise SLNB and improve the identification rate of SLNs.

Methods: Twenty-seven patients with suspected breast cancer based on the results of the clinical examination and imaging were enrolled in the study. Computed tomographic lymphography (CTLG) followed by CT three-dimensional reconstruction was performed to determine the localization of SLNs and lymphatics on the body surface preoperatively.

Adverse events associated with nilotinib in chronic myeloid leukemia: mechanisms and management strategies.

: Nilotinib is a second-generation tyrosine kinase inhibitor (TKI) targeting BCR/ABL, which is used for the first-line treatment of newly diagnosed chronic myeloid leukemia (CML) patients and the second-line treatment of most CML patients who are resistant or intolerant to prior therapy that includes imatinib. In addition to common adverse reactions, long-term use of nilotinib shows some toxicities that are different from those of occurring during other BCR/ABL TKI treatments, such as cardiovascular toxicity. It is life-threatening, which would affect not only the choice of initial treatment of CML patients but also the safety of long-term medication.

Crosstalk between alveolar macrophages and alveolar epithelial cells/fibroblasts contributes to the pulmonary toxicity of gefitinib.

Gefitinib is an epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor indicated for the first-line treatment of patients with metastatic or advanced non-small cell lung cancer (NSCLC) whose tumors have specific EGFR mutations. Pulmonary toxicity is one of the fatal adverse effects of gefitinib and the underlying mechanism remains unclear. Here we demonstrated that alveolar macrophages contributed to gefitinib-induced pulmonary toxicity through promoting alveolar epithelial cells to undergo epithelial to mesenchymal transition (EMT) and inducing activation and antiapoptotic effect in fibroblasts.

Identification and preservation of stained non-sentinel lymph nodes in breast cancer.

Sentinel lymph nodes (SLNs) are the first lymph nodes that receive lymphatic drainage from the breast. However, all stained lymph nodes are dissected as SLNs during surgery. The present study aimed to identify and preserve the stained non-SLNs and evaluate the safety during sentinel lymph node biopsy (SLNB) in breast cancer.

COVID-19 epidemic: a special focus on diagnosis, complications, and management.

Introduction: The outbreak of COVID-19 caused by SARS-CoV-2 infection has become a serious hazard to global health. Apart from attacking respiratory system, it can induce multiorgan dysfunction, including cardiovascular system, liver, kidney, gastrointestinal, nervous system, and immune system. However, there are few reviews focusing on summary and comparison of diagnostic methods and complications induced by SARS-CoV-2 infection, which places a significant limit on the effective management.

Cardiovascular toxicity induced by anti-VEGF/VEGFR agents: a special focus on definitions, diagnoses, mechanisms and management.

Introduction: Vascular endothelial growth factor (VEGF) is a key target in cancer therapy. However, cardiovascular safety has been one of the most challenging aspects of anti-VEGF/VEGF receptor (VEGFR) agent development and therapy. While accurate diagnostic modalities for assessment of cardiac function have been developed over the past few decades, a lack of an optimal definition and precise mechanism still places a significant limit on the effective management of cardiovascular toxicity.

Clinicopathological features of granulomatous lobular mastitis and mammary duct ectasia.

Granulomatous lobular mastitis (GLM) and mammary duct ectasia (MDE) are inflammatory diseases. However, only a limited number of studies have focused on characterizing their clinicopathological features. The aim of the present study was to investigate the etiology, clinicopathological characteristics and diagnosis of GLM and MDE.

Galactogram Grading System for Identifying Breast Cancer With Nipple Discharge.

Background: Galactography is a primary recommendation in the management of nipple discharge (ND), which may be caused by benign or malignant lesions. We aimed to establish a galactogram grading system (GGS) and investigate its role in identifying breast cancer with ND.

Langer's axillary arch lymph node metastasis in breast cancer patients: A prospective clinical study.

Background And Objectives: Latissimus dorsi, an anatomical landmark for axillary lymph node dissection, was reported to harbor an anatomical variation named Langer's axillary arch (LAA). However, the incidence and clinical significance of LAA in breast cancer remain obscure.

Methods: We conducted a six-year prospective study, including 1724 breast cancer patients in Qilu hospital between January 2012 to February 2018.

Relationship between Upper Extremity Lymphatic Drainage and Sentinel Lymph Nodes in Patients with Breast Cancer.

Purpose: The purpose of this study was to identify the relationship between upper extremity lymphatics and sentinel lymph nodes (SLNs) in breast cancer patients.

Methods: Forty-four patients who underwent axillary reverse mapping (ARM) during axillary lymph node dissection (ALND) with SNL biopsy (SLNB) between February 2017 and October 2017 were investigated. ARM was performed using indocyanine green (ICG) to locate the upper extremity lymphatics; methylene blue dye was injected intradermally for SLN mapping.

Bisdemethoxycurcumin protects against renal fibrosis via activation of fibroblast apoptosis.

Renal fibrosis is the common final outcome of nearly all progressive chronic kidney diseases (CKD) that eventually develop into end-stage renal failure, which threatens the lives of patients. Currently, there are no effective drugs for the treatment of renal fibrosis. However, studies have shown that certain plant natural products have a fibrosis-alleviating effect.

Discovery of rare ancestry-specific variants in the fetal genome that confer risk of preterm premature rupture of membranes (PPROM) and preterm birth.

Background: Preterm premature rupture of membranes (PPROM) is the leading identifiable cause of preterm birth, a complication that is more common in African Americans. Attempts to identify genetic loci associated with preterm birth using genome-wide association studies (GWAS) have only been successful with large numbers of cases and controls, and there has yet to be a convincing genetic association to explain racial/ethnic disparities. Indeed, the search for ancestry-specific variants associated with preterm birth has led to the conclusion that spontaneous preterm birth could be the consequence of multiple rare variants.

MiR-770 suppresses the chemo-resistance and metastasis of triple negative breast cancer via direct targeting of STMN1.

Chemo-resistance and metastasis of triple negative breast cancer (TNBC) contributed the most of treatment failure in the clinic. MicroRNAs (miRNAs) have been proved to be involved in many biological processes and diseases. In this study, we aimed to determine the role of miR-770 in the regulation of chemo-resistance and metastasis of TNBC.

Background/aims: Increasing evidence indicates that Huaier extract has promising therapeutic effects against cancer. However, the mechanisms that underlie its anti-tumor effects remain unclear. In recent years, various studies have shown that long noncoding RNAs (lncRNAs) play a critical role in the regulation of cancer development and progression.

Precise intraoperative sentinel lymph node biopsies guided by lymphatic drainage in breast cancer.

The purpose of this study was to present a novel surgical method for intraoperative precise sentinel lymph node biopsy (SLNB) and to determine its clinical efficacy and sensitivity in breast cancer patients. The sentinel lymph nodes (SLNs) were preoperatively evaluated by axillary ultrasound. The intraoperative detection of SLNs was guided by lymphatic drainage pathway.

Huaier extract restrains the proliferative potential of endocrine-resistant breast cancer cells through increased ATM by suppressing miR-203.

Endocrine therapy is one of the main treatments for breast cancer patients in the early stages. Tamoxifen and fulvestrant are the major drugs of endocrine therapy for breast cancer patients. However, acquired drug resistance often caused treatment failure and relapse for patients, which is a major clinical problem.

Periareolar incision for the management of benign breast tumors.

Benign breast tumors (BBTs) are common in women. The traditional surgical resection method for the various types of BBT leaves obvious scars and affects the appearance of the breast. The present study introduces the experience of a single institution in the treatment of BBT by periareolar incision.

Comparison of adjuvant ED and EC-D regimens in operable breast invasive ductal carcinoma.

In China, the adjuvant epirubicin and docetaxel (ED) regimen is widely used as a substitute for the epirubicin and cyclophosphamide followed by docetaxel (EC-D) regimen in patients with operable breast cancer. However, their equivalence has not yet been demonstrated. This retrospective study compared these two adjuvant regimens as regards feasibility, safety and efficacy.
