Acoustic Trauma Changes the Parvalbumin-Positive Neurons in Rat Auditory Cortex.

Acoustic trauma is being reported to damage the auditory periphery and central system, and the compromised cortical inhibition is involved in auditory disorders, such as hyperacusis and tinnitus. Parvalbumin-containing neurons (PV neurons), a subset of GABAergic neurons, greatly shape and synchronize neural network activities. However, the change of PV neurons following acoustic trauma remains to be elucidated.

Contrast-enhanced dynamic and diffusion-weighted magnetic resonance imaging at 3.0 T to assess early-stage nasopharyngeal carcinoma.

The present study aimed to assess early-stage nasopharyngeal carcinoma (NPC) with dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and diffusion-weighted imaging (DWI) at 3.0 T. A total of 44 patients newly diagnosed with NPC were included in the present study.

High expression of NDRG3 associates with positive lymph node metastasis and unfavourable overall survival in laryngeal squamous cell carcinoma.

N-myc downstream-regulated gene 3 (NDRG3), which belongs to the NDRG family, is believed to play important roles in human cancer. In this present study, one-step quantitative reverse transcription-polymerase chain reaction (qPCR) and western blotting tests with 10 fresh-frozen laryngeal squamous cell carcinoma (LSCC) samples and immunohistochemistry (IHC) analysis in 109 LSCC cases were performed to investigate the relationship between NDRG3 expression and the clinicopathological characteristics of LSCC. Results demonstrated that NDRG3 mRNA and protein expression levels were statistically higher in LSCC tissues than that in non-cancerous tissues (all p<0.

All-trans retinoic acid modulates the balance of ADAMTS13 and VWF in human microvascular endothelial cells.

Purpose: To better understand the antithrombotic property of All-trans retinoic acid (ATRA), we investigated whether ATRA may affect the balance between ADAMTS13 and von Willebrand factor (VWF) in human microvascular endothelial cell.

Methods: Compared to tumor necrosis factor-alpha (TNF-α), we observed the effects of ATRA on the expression of ADAMTS13 and VWF. ADAMTS13mRNA in human microvascular endothelial cell (HMEC-1 cell line) were detected by real-time polymerase chain reaction amplification (RT-PCR).

MicroRNA-338-3p inhibits cell proliferation in hepatocellular carcinoma by target forkhead box P4 (FOXP4).

MicroRNAs (miRNAs) are a class of small, non-coding RNAs, which have demonstrated to important gene regulators, and have critical roles in diverse biological processes including cancer cell proliferation. Previous studies suggested microRNA-338-3p (miR-338-3p) was down-regulated and play tumor suppressor roles in gastric cancer, colorectal carcinoma and lung cancer. However, the role of miR-338-3p in hepatocellular carcinoma (HCC) is still unclear.

(Bortezomib plus lenalidomide/thalidomide)- vs. (bortezomib or lenalidomide/thalidomide)-containing regimens as induction therapy in newly diagnosed multiple myeloma: a meta-analysis of randomized controlled trials.

The aim of the study was to perform a meta-analysis of the efficacy and safety of (bortezomib plus lenalidomide/thalidomide)- vs. (bortezomib or lenalidomide/thalidomide)-containing regimens as induction therapy in newly diagnosed multiple myeloma. We searched electronic and printed sources for relevant articles published.

CD4 + CD25high regulatory T cell numbers and FOXP3 mRNA expression in patients with advanced esophageal cancer before and after chemotherapy.

We evaluated the changes in CD4 + CD25(high) regulatory T (Treg) cells and FOXP3 mRNA expression in patients with advanced esophageal cancer as well as its clinical significance. For this purpose, the frequencies of peripheral blood Treg cells in 68 patients with advanced esophageal cancer and 40 healthy controls were determined by flow cytometry, and FOXP3 mRNA expression in Treg cells of 40 patients was determined by RT-PCR. The data show that Treg cell numbers were significantly higher (P < 0.

Endoscopic removal of esophageal impacted dentures.

Objectives: A retrospective study was conducted on 6 patients with esophageal impacted dentures removed via rigid esophagoscopy.

Methods: Six patients with esophageal impacted dentures were treated in our department, and the following technique was successfully performed. With the patients under general anesthesia, we inserted the endoscope to visualize the impacted dentures, fixed them with forceps, and then stuffed several cotton slivers soaked in saline solution into the esophagus around the dentures with another forceps.

[Prevention of anterior glottic stenosis after CO2 laser cordectomy with chitosan].

Objective: To observe the effect of immediate topical application of chitosan on preventing anterior glottic stenosis (AGS) after microsurgical resection of both vocal fold with CO2 laser, including the anterior commissure, in a canine model.

Methods: Sixteen canine larynges were injured by microresecting procedure of both vocal folds with CO2 laser. The dogs were randomly divided into two groups, chitosan group and control group.
