HIF‑1α promotes the stemness of oesophageal squamous cell carcinoma by activating the Wnt/β‑catenin pathway.

Hypoxia‑inducible‑factor 1α (HIF‑1α) is a marker for poor prognosis in the majority of the cancer types, and it has been revealed to be essential for maintaining cancer stem cells (CSCs). In the present study, it was determined that the expression of HIF‑1α and CSC‑related genes under hypoxic conditions was upregulated. Stable knockdown of HIF‑1α significantly inhibited cell proliferation, migration and tumour growth in vivo in oesophageal squamous cell carcinoma (ESCC).

Clinical analysis of high-intensity focussed ultrasound ablation for abdominal wall endometriosis: a 4-year experience at a specialty gynecological institution.

Objective: To evaluate the long-term clinical effect of high-intensity focussed ultrasound (HIFU) as a non-invasive modality for ablation of abdominal wall endometriosis (AWE) foci.

Methods: All women who were diagnosed with cutaneous endometriosis and underwent HIFU ablation and 4-year follow-up were included. Patient symptoms, imaging performed, HIFU ablation, recurrence, lesion location, size and number were collected and analyzed.

Effect of pre-treatment with gonadotropin-releasing hormone analogue GnRH-α on high-intensity focussed ultrasound ablation for diffuse adenomyosis: a preliminary study.

Objectives: To evaluate the efficacy and safety of GnRH-α pre-treatment with HIFU ablation for diffuse adenomyosis.

Methods: From January 2014 to December 2016, 61 patients were divided into two groups. Twenty-three patients with larger uteri received pre-treatment with GnRH-α and were then subjected to HIFU, and 38 patients underwent HIFU alone.

Ultrasensitive enhanced chemiluminescence enzyme immunoassay for the determination of alpha-fetoprotein amplified by double-codified gold nanoparticles labels.

A novel enhanced chemiluminescent (CL) immunoassay for ultrasensitive determination of alpha-fetoprotein (AFP) was reported. The method made full use of 4-(4'-iodo)phenylphenol (IPP) as a new potential signal enhancer and double-codified gold nanoparticles (DC-AuNPs) labels modified with horseradish peroxidase (HRP)-conjugated anti-AFP used for further signal amplification. This protocol involved a sandwich format, in which the antigen in the sample was first captured by the immobilized primary antibody on the surface of magnetic beads, and then recognized by the second antibody labeled with DC-AuNPs.
