Selenium alleviates chromium stress and promotes chromium uptake in As-hyperaccumulator Pteris vittata: Cr reduction and cellar distribution.

Arsenic-hyperaccumulator Pteris vittata exhibits remarkable absorption ability for chromium (Cr) while beneficial element selenium (Se) helps to reduce Cr-induced stress in plants. However, the effects of Se on the Cr uptake and the associated mechanisms in P. vittata are unclear, which were investigated in this study.

Foliar-selenium enhances plant growth and arsenic accumulation in As-hyperaccumulator Pteris vittata: Critical roles of GSH-GSSG cycle and arsenite antiporters PvACR3.

It is known that selenium (Se) enhances plant growth and arsenic (As) accumulation in As-hyperaccumulator Pteris vittata, but the associated mechanisms are unclear. In this study, P. vittata was exposed to 50 μM arsenate (AsV) under hydroponics plus 25 or 50 μM foliar selenate.

Delayed pathological finding of a small fish bone causing a purulent cyst in the pharynx: a case report.

We describe the case of a patient who swallowed a small fish bone and felt it lodge in her pharynx, but failed to seek medical attention in a timely manner. One week later, no foreign body was found in the hypopharynx or larynx, but a small purulent cyst was present in the epiglottic vallecula. A computed tomography scan showed a high-density area on the lingual surface of the epiglottis, which was considered to represent an embedded fish bone.

Analysis of a delayed diagnosis of carotid artery aneurysm presenting as a parapharyngeal space infection.

It is very rare for extracranial carotid artery dissection to present as a carotid pseudoaneurysm. A delayed diagnosis and delayed treatment will lead to rupture of carotid pseudoaneurysm and massive hemorrhage and death. In this paper, we reviewed the progress of the disease in one patient and reviewed the relevant literature reports to understand the characteristics of the disease.

Characteristics of lingual thyroglossal duct cysts under flexible laryngoscopy and treatment approaches.

Objectives: Lingual thyroglossal duct cysts (LTGDCs) are clinically rare and easily misdiagnosed as epiglottic cysts. Misdiagnosis leads to mistreatment; thus,simple diagnosis is important. This study aimed to investigate the characteristics of LTGDCs with flexible laryngoscopy and imaging, improve their diagnosis and explore surgical methods for patients undergoing an initial operation and patients with recurrence.

[Anti-EGFR monoclonal antibodies in recurrent and/or metastatic head and neck squamous cell carcinoma: a meta-analysis].

Objective: To systematically review the literature regarding the effectiveness and adverse reaction of epidermal growth factor receptor-monoclonal antibodies (RGFR-mAbs) in improving the prognosis of R/M HNSCC so as to develop evidence-based recommendations for treatment.

Methods: Comprehensively searches were performed for the databases of CBM, PubMed, Embase and Cochrane to identify the published studies on the effect of RGFR-mAbs in recurrent and/or metastatic head and neck squamous carcinoma (R/M HNSCC) patients. Primary outcomes included overall survival (OS), progression-free survival (PFS) and overall response rate (ORR).

[Anti-EGFR monoclonal antibodies in locally advanced head and neck squamous cell carcinoma: a Meta-analysis].

Objective: To perform a Meta-analysis of all randomized controlled trials that compared the efficacy and adverse events profile of Mabs for LA HNSCC.

Method: Several databases were searched, including CBM, PUBMED, EMBASE, and CENTRAL. Primary outcomes included overall response rate (ORR), overall survival (OS), progression-free survival (PFS).

[Clinicopathologic features and risk factors of bilateral cervical lymph node metastasis in head and neck squamous cell carcinoma].

Objective: To investigate the clinicopathologic features and associated risk factors for bilateral neck node metastasis (BNM) in head and neck squamous cell carcinoma (HNSCC).

Methods: Two hundred eighty-six cases with HNSCC were retrospectively studied, including 83 cases of oral tongue cancers, 101 cases of hypopharyngeal cancers and 102 cases of supraglottic laryngeal cancers. All patients had unilateral or bilateral cervical lymph node metastasis confirmed by postoperative pathologic examinations.

[Preliminary report of laryngeal preservation in the surgical salvage of recurrent laryngeal cancer].

Objective: To explore the plausibility of laryngeal preservation in salvage surgery of recurrent laryngeal carcinoma.

Methods: Comprehensive clinical and radiological assessments on a specific group of patients with recurrent laryngeal cancer and their relapsed tumors were carried out to determine the methods and indications of salvage surgery for preservation of laryngeal functions. Salvage surgery with preservation of larynx was performed in a selective of 36 laryngeal cancer patients with relapsed tumors in their larynges after radiotherapy or partial laryngectomies.

[An objective evaluation of nasal airway obstruction by enlarged adenoids in children].

Objective: To evaluate the clinical application value of nasal airway obstruction objectively and quantificationally by acoustic rhinometry (AR) in children with adenoid hypertrophy.

Method: Thirty patients with adenoid hypertrophy were examined with AR and questionnaire at preoperative and eight weeks after surgery. The values of AR were compared with those of 27 normal controls.

[Phonation assessment of voice restoration after laryngectomy].

Objective: To take an objective phonation assessment for the patients who have taken the tracheo-esophageal (TE) shunt procedure after total laryngectomy.

Method: Twenty-four patients after TE shunt procedure were selected as TE group. Esophageal speakers after total laryngectomy and normal subjects were considered as controls.
