Objective: To observe and compare the effects and complications of endoscope-assisted transoral approach and lateral cervical approach in the resection of parapharyngeal space (PSS) tumors.

Methods: From January 2013 to September 2021, 69 patients with parapharyngeal space tumors in the Affiliated Hospital of Jiangnan University were divided into the control group ( = 37) and the observation group ( = 32) according to the mode of operation. The tumors in the parapharyngeal space were resected by the lateral cervical approach in the control group, and the tumors in the parapharyngeal space were removed by endoscopy-assisted transoral approach in the observation group.

A novel method for benzo(α)pyrene (Bαp) enrichment from an oil matrix was developed by using magnetic nanoparticles (FeO@dopamine/graphene oxide, FeO@DA/GO) as extraction absorbents, and the chemical properties of the synthesized nanoparticles were characterized. Various parameters were investigated to optimize the extraction of Bαp from oils. Under optimal conditions (pH, 4; extraction time, 0.

This paper constructs the measurement index of core competence by text analysis method and empirically tests the impact of core competence on stock price synchronicity. We find that the stronger the core competence, the lower the stock price synchronicity, and mechanism test shows that core competence reduces the stock price synchronicity by enhancing the transparency of corporate information, which is still valid under a series of robustness tests. Further research shows that:(1) when the corporate governance environment is poor (higher level of internal earnings management, lower quality of accounting information, greater separation of ownership and control, lower shareholding ratio of external institutional investors, weaker product market competition, less media attention), the core competence has a more significant effect on the decline of stock price synchronization; (2)vertically, the dynamic improvement of core competence in the time dimension can play a role in stabilizing stock price synchronization; (3)after distinguishing the types of core competence, we find that the core competence related to information disclosure is more helpful to reduce the stock price synchronization; (4)after the CSRC forces listed companies to disclose the core competence information in the annual report, the core competence plays a stronger role in reducing the stock price synchronization.

This study aims to investigate the efficacy and safety of local lauromacrogol injection in the treatment of hypopharyngeal hemangioma. From Aug 2015 to May 2021, 13 consecutive patients suffering from hypopharyngeal hemangioma underwent local lauromacrogol injection assisted by endoscope in this prospective clinical series. All patients were followed up regularly and the therapeutic effects and complications were observed.

Objective: The aim of this meta-analysis is to compare the efficacy of hyperbaric oxygen therapy (HBOT) and intratympanic steroids (ITS) as salvage treatment for patients with refractory sudden sensorineural hearing loss (SSNHL).

Data Sources: Electronic search was performed in the PubMed, Embase, Cochrane Library, CNKI, and Wan Fang databases to June 1, 2020.

Methods: For each outcome measure, a forest plot was generated and a pooled relative risk (RR) or mean difference (MD) was calculated.

Article Synopsis
  • Branchio-oto-renal spectrum disorder (BORSD) includes hearing loss and malformations in the ears, with possible associated cysts and kidney issues.
  • A specific genomic deletion related to this condition was identified in a patient with sporadic deafness, revealing a mutation in a key gene associated with BORSD.
  • This discovery demonstrates how advanced sequencing techniques can help to uncover complex genetic alterations that contribute to hearing loss.

Tumor-associated macrophages (TAMs) are important components of the tumor microenvironment, which are characterized by pro-tumor M2 phenotype and correlate with poor survival of nasopharyngeal carcinoma (NPC). Heme oxygenase-1 (HO-1) plays a crucial role in macrophage polarization toward M2 phenotype, but its prognosis significance in NPC has been rarely determined. To gain insights into the HO-1 expression profile and to determine the clinical significance of HO-1 in NPC, we performed immunohistochemistry analyses in 126 NPC specimens.

The current study developed a cheap and effective method for the simultaneous extraction of 14 heterocyclic aromatic amines (HAAs) in food matrix. Core-shell FeO@PDA nanoparticles were constructed and acted as the magnetic solid-phase extraction adsorbent to separate and purify HAAs from meat products for the first time. Then, UPLC-MS/MS technique was employed to identify and quantify the HAAs easily.

Combination therapy with conventional chemotherapeutic drugs strongly demonstrates a good approach to reduce cytotoxicity, resistance, and the dose of the potent anticancer drugs. The purpose of this research was to design and characterize liposome incorporating celecoxib (CEL) and doxorubicin hydrochloride (DOX) and investigate the anti-tumor efficacy of this combination on different tumor cells. A simple comparison study had been performed for liposomes formulation using thin-film hydration method and pH-gradient method.

To date, no specific biomarkers for idiopathic sudden sensorineural hearing loss (ISSHL) have been used. The aim of this study is to investigate whether prestin, the motor protein of cochlear outer hair cells, could be used as a biomarker candidate for the diagnosis and prognosis judgement of ISSHL. Blood samples of 14 ISSHL patients and 28 control patients without history of hearing loss were collected.

Purpose: Cetuximab, an anti-epidermal growth factor receptor monoclonal antibody, carries the potential for combination treatment against nasopharyngeal carcinoma (NPC). We conducted a meta-analysis to assess the possible benefits and safety between the combination treatment with cetuximab and conventional treatment in NPC patients. Skin toxicity (ST) associated with additional cetuximab was evaluated as well.

Heparosan polysaccharide, known as a heparin precursor, can be used in drug delivery systems due to its good biocompatibility and anti-cancer effect. But few studies on the cellular uptake mechanism of heparosan polysaccharide-based nanocarrier have been investigated. Therefore, the intracellular trafficking and the uptake mechanism of heparosan-based micelles by different tumor cells were investigated in this study.

In this study, we reported a redox-responsive drug delivery system (DDS) based on heparosan and deoxycholic acid conjugates (HSDs) for effective treatment of laryngopharyngeal carcinoma. The amphiphilic HSDs can self-assemble into stable nanoscale micelles in aqueous medium with favorable drug loading capacity for doxorubicin (DOX). The HSD micelles can exhibit glutathione (GSH)-triggered drug release behavior and reach a nearly 100% release rate in a high GSH level (10 mM) environment.
