Nasopharyngeal carcinoma (NPC) is a malignant tumor originating from nasopharyngeal mucosa. Anoikis, a form of programmed cell death induced by detachment from the extracellular matrix, normally prevents metastasis. Resistance to anoikis in cancer cells can enhance their metastatic potential.

Methods: Retrospective analysis was conducted on 184 laryngeal leukoplakia patients treated in Ningbo Beilun People's Hospital from January 2018 to October 2021. Based on the inclusion and exclusion criteria, 128 eligible patients were included, including 64 patients who underwent suspension laryngoscopic mucosal dissection (control group) and 64 patients who underwent cryolyrectomy (study group).
To study the effect of Salidroside on nasopharyngeal carcinoma (NPC) cells and its mechanism. NPC cells were cultured, MTT was used to detect the effect of Salidroside on cell proliferation, apoptosis detected by flow cytometry assay, Western blot was used to detect the related protein expression. MiR-4262 and GRP78 used qRT-PCR for evaluation.

However, the relationship between exercise, mTOR activation and leucine-sensing requires further clarification. Two month old Sprague-Dawley rats were subjected to aerobic exercise (treadmill running at 20 m/min, 6° incline for 60 min) and resistance exercise (incremental ladder climbing) for 4 weeks.

A novel diagnostic biomarker is of great importance for the improvement of NPC management. This study aimed to state the biological function and diagnostic values of miR-762 in NPC to provide a novel insight into the detection and therapy of NPC.

Sixty Sprague-Dawley male rats were randomly divided into six groups: control group, exercise group, exercise and PSP (50, 100, or 200 mg kg-1)-treated groups, and exercise and caffeine (10 mg kg-1)-treated group (positive control). In the exercise groups, rats were put on a treadmill and forced to run for 30 min once a day for 6 consecutive days.

Methods: 49 4-week male rats were randomly assigned to two groups: control group( C) with 6 rats with normal diet and MS model group with 43 rats with high fat diet. After 18 weeks, assigned the successful MS modeling high fat diet rats to model control group( MC) with 8 rats and model exercise group( ME) with 8 rats.

Chronic sinusitis (chronic rhinosinusitis, CRS) is a chronic inflammatory disease of the nasal cavity and paranasal sinuses, pathogenesis of which is not yet completely elucidated. MicroRNA has been shown to extensively be involved in immune response. To analyze the differential expression of miRNAs in chronic sinusitis, with or without nasal polyps (nasal polyps, NP), seven miRNAs (miR- 181b, miR-26b, miR-155, miR-146a, miR-125b, miR-124 and miR-92a) that are associated with inflammation were selected to be quantifying by RT-qPCR in 40 clinical samples and 5 controls.

However, expression of the gene carried by adenovirus is instantaneous, which undoubtedly limits its clinical application. Lentivirus acts as a carrier that can stably and continuously express genes.

Methods: Healthy rats were randomly divided into two groups. The left ears of the animals in group I were injected with lentivirus carrying EGFP (n=10) via scala media lateral wall cochleostomies, and the left ears of the animals in group II were similarly injected with artificial endolymph (n=10).

Noise induced hearing loss (NIHL) is a complex occupational hazard caused by an interaction between genetic and environmental factors. Millions of Chinese industrial people are daily exposed to high level of noise. Although the environmental risk factors have been studied extensively, the nature of the genetic factors contributing to HIHL has not yet been clarified.
