The fact that serum thyrotropin (TSH) levels increase with age may influence the diagnosis of thyroid diseases in older adults. This study aimed to establish an age-specific serum TSH reference range, examine the prevalence of thyroid diseases in older adults ≥65 years, and analyze the risk factors. A cross-sectional study of adult populations in 10 cities in China was conducted from 2010 to 2011.

In-stent restenosis (ISR) is the most common complication associated with percutaneous coronary intervention (PCI). Although some studies have reported an association between lectin-like oxidized low-density lipoprotein receptor-1 (LOX-1) and ISR, not enough clinical validation data are available to support this link. Here, we report our cross-sectional study aimed at exploring the feasibility of LOX-1 as a biomarker for the prognostic diagnosis of patients undergoing PCI.

Objective: Acute seizures induced dendritic formation and synaptogenesis promotes aberrant circuitry development and further aggravates underlying conditions towards chronic epilepsy. The G protein-coupled receptor kinase-5 (GRK5) served as a key modulator in neurogenesis and the establishment of functional neuronal circuitry. This included dendritic development, as its dysfunction could cause different central nervous system disorders, including Alzheimer's disease.

Background: For patients with non-small-cell lung cancer (NSCLC) and multiple brain metastases, whole-brain irradiation (WBI) is a standard-of-care treatment, but its effects on neurocognition are complex and concerning. We compared the efficacy of an epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor (TKI), icotinib, versus WBI with or without chemotherapy in a phase 3 trial of patients with EGFR-mutant NSCLC and multiple brain metastases.

Methods: We did a multicentre, open-label, parallel randomised controlled trial (BRAIN) at 17 hospitals in China.

To investigate the therapeutic effect of minimally invasive interventional treatment of brain hematoma, 128 patients with brain hematoma were randomly divided into two groups, including observation group (64 cases) and control group (64 cases). The observation group was performed with minimally invasive interventional therapy and drug conservative therapy was used in the control group. Clinical curative effect, treatment of neural function defect score, and quality of life score were recorded.

Legionella pneumophila, the causative bacterium for Legionnaires' disease, hijacks host membrane trafficking for the maturation of the Legionella-containing vacuole (LCV). The LCV membrane mainly contains PtdIns4P, which is important for anchoring many secreted Legionella effectors onto the LCV. Here, we identify a cryptic functional domain (LepB_NTD) preceding the well-characterized RabGAP domain in the Legionella Dot/Icm type IV secretion system effector LepB.

From diagnosis to therapy in lung cancer: management of CT detected pulmonary nodules, a summary of the 2015 Chinese-German Lung Cancer Expert Panel.

Transl Lung Cancer Res

August 2016

Division of Surgical Oncology and Thoracic Surgery, University Medical Centre Mannheim, Medical Faculty Mannheim, Heidelberg University, Mannheim, Germany.

Article Synopsis
  • The first Chinese-German Lung Cancer Expert Panel convened in November 2015 to address challenges in lung cancer diagnosis and treatment, particularly concerning screening.
  • Improved risk classification and advanced imaging techniques are critical since over half of the initial screenings result in false positives with existing National Lung Screening Trial criteria, which may not be suitable for the Chinese population due to different risk factors.
  • The discussion highlighted the importance of using chest CT for better identification of pulmonary nodules and explored novel diagnostic and treatment methods to improve lung cancer screening outcomes.

Background: The goal of eliminating iodine deficiency worldwide was successfully achieved in China after the implementation of a mandatory universal salt iodization program for the last 16 years. Thus, China has been assessed as a country with more than adequate iodine levels. This survey aimed to investigate the current iodine status in China and the effects of an increased iodine intake on the spectrum and prevalence of thyroid disorders.

High-density lipoprotein of patients with breast cancer complicated with type 2 diabetes mellitus promotes cancer cells adhesion to vascular endothelium via ICAM-1 and VCAM-1 upregulation.

The Institute of Cardiovascular Sciences and Institute of Systems Biomedicine, School of Basic Medical Sciences, and Key Laboratory of Molecular Cardiovascular Sciences of Ministry of Education, Peking University Health Science Center, Beijing, 100191, China.

Adhesion of disseminating tumor cells to vascular endothelium is a pivotal starting point in the metastasis cascade. We have shown previously that diabetic high-density lipoprotein (HDL) has the capability of promoting breast cancer metastasis, and this report summarizes our more recent work studying the role of abnormal HDL in facilitating the adhesion of the circulating tumor cells to the endothelium. This is an initiating step in breast cancer metastasis, and this work assesses the role of ICAM-1 and VCAM-1 in this process.

We studied the imaging and histopathological features of primary hepatic diffuse large B-cell lymphoma in order to explore the clinicopathological features, diagnosis, differential diagnoses, and treatment. Immunolabelling was performed in seven cases of primary hepatic diffuse large B-cell lymphoma using histological and immunohistochemical techniques. The clinical manifestations; imaging, histopathological, and immunohistochemical features; treatment; and prognosis of primary hepatic diffuse large B-cell lymphoma were observed and analyzed in light of the relevant literature.

Background: The aim of the present study was to investigate whether the therapeutic efficacy of acarbose and metformin is correlated with baseline HbA1c levels in Chinese patients with newly diagnosed type 2 diabetes mellitus (T2DM).

Methods: Data for 711 subjects were retrieved from the MARCH (Metformin and AcaRbose in Chinese as initial Hypoglycemic treatment) trial database and reviewed retrospectively. Patients were grouped according to baseline HbA1c levels (<7%, 7%-8%, and >8%) and the results for these three groups were compared between acarbose and metformin treatments.

The epidermal growth factor receptor (EGFR)/PI3K/AKT signaling pathway aberrations play significant roles in breast cancer occurrence and development. However, the status of EGFR and AKT1 gene copy numbers remains unclear. In this study, we showed that the rates of EGFR and AKT1 gene copy number alterations were associated with the prognosis of breast cancer.

December 2014

School of Biomedical Engineering, Shanghai Jiao Tong University, Shanghai, China. Electronic address:

A virtual reality (VR) based vascular intervention simulation system is introduced in this paper, which helps trainees develop surgical skills and experience complications in safety remote from patients. The system simulates interventional radiology procedures, in which flexible tipped guidewires are employed to advance diagnostic or therapeutic catheters into vascular anatomy of a patient. A real-time physically-based modeling approach ground on Kirchhoff elastic rod is proposed to simulate complicated behaviors of guidewires and catheters.

Breast cancer is a disease of cell cycle, and the dysfunction of cell cycle checkpoints plays a vital role in the occurrence and development of breast cancer. We employed multi-gene fluorescence in situ hybridization (M-FISH) to investigate gene copy number aberrations (CNAs) of 4 genes (Rb1, CHEK2, c-Myc, CCND1) that are involved in the regulation of cell cycle, in order to analyze the impact of gene aberrations on prognosis in the young breast cancer patients. Gene copy number aberrations of these 4 genes were more frequently observed in young breast cancer patients when compared with the older group.

The rarely occurring vertebrovertebral arteriovenous fistula (VVAVF) is characterized by abnormal direct communications between the vertebral artery or its branches and the neighboring venous system. We present our experience using a stent graft to occlude a chronic, traumatic VVAVF. A 40-year-old woman with dizziness and loud bruits from the occiput underwent digital subtraction angiography (DSA), which revealed a VVAVF with pseudoaneurysm at the C5-C6 level, with retrograde flow from the right vertebral artery.
