The relationship between semen quality in male infertility clinic patients and bisphenol A：A Chinese cross-sectional study.

Bisphenol A (BPA) is a growing concern as an endocrine-disrupting chemical due to its adverse health effects. However, the association between BPA and sperm quality in adult human males remains unclear. The aim of this study was to assess the daily life exposure level of BPA and analyze its correlation with sperm quality in males.

Associations between per- and polyfluoroalkyl substances exposure and thyroid hormone levels in the elderly.

This study aimed to measure the exposure of the elderly to per- and polyfluoroalkyl substances (PFAS) and explore their effects on thyroid hormone levels. A cross-sectional study of plasma samples from 746 elderly people (aged >60 years) from Taiyuan, China was conducted. Fourteen PFASs were determined using liquid chromatography-tandem mass spectrometry and five thyroid function indicators, thyroid-stimulating hormone (TSH), thyroxine (T4), triiodothyronine (T3), free T4 (FT4), and free T3 (FT3), using an enzyme-linked immunoassay.

Whole transcriptome sequencing and competitive endogenous RNA regulation network construction analysis in benzo[a]pyrene-treated breast cancer cells.

Breast cancer is the most common malignant tumor in women worldwide, and environmental pollutants are considered to be risk factors. Currently, most studies into benzo[a]pyrene (B[a]P)-induced breast cancer focus on biological effects such as proliferation, invasion, and metastasis, DNA damage, estrogen receptor (ER)-related molecular mechanisms, oxidative damage, and other metabolic pathways. This study aims to provide insights into the role of B[a]P in breast cancer development through RNA-seq and bioinformatics analysis and construction of a competing endogenous RNA (ceRNA) regulatory network.

Bladder leiomyoma presenting as dyspareunia: Case report and literature review.

Introduction: Leiomyoma of the bladder is a rare tumor arising from the submucosa. Most patients with bladder leiomyoma may present with urinary frequency or obstructive urinary symptoms. However, there are a few cases of bladder leiomyoma coexisting with uterine leiomyoma presenting as dyspareunia.

Evaluation of the otolith function using c/oVEMPs in patients with Ménière's disease.

Background: Cervical and ocular vestibular evoked myogenic potentials (c/oVEMPs) reflect otolith function. Up-to-date, there are no published reports on the systemic evaluation of otolith function in Ménière's Disease (MD) nor are there any reports on the differences in VEMPs between patients with early and late stage MD. The aim of this study was to evaluate the difference in c/oVEMPs between patients with MD and normal controls, as well as between patients with early and late stage MD.

Evaluation of the utricular and saccular function using oVEMPs and cVEMPs in BPPV patients.

Background: It is well-known that ocular vestibular evoked myogenic potentials (oVEMPs) predominantly reflect utricular function whilst cervical vestibular evoked myogenic potentials (cVEMPs) reflect saccular function. To date, there are no published reports on the systemic evaluation of utricular and saccular function in benign paroxysmal positional vertigo (BPPV), nor are there any reports on the differences in VEMPs between patients with recurrent and non-recurrent BPPV. The aim of this study was to evaluate the difference in cervical and ocular (c/o)VEMPs between patients with BPPV and normal controls, as well as between patients with recurrent and non-recurrent BPPV.

Objective: To investigate the treatment efficacy of tympanostomy microtube placement surgery for middle ear atelectasis.

Methods: A retrospective analysis was conducted on 26 patients (28 ears) with middle ear atelectasis, who complained fullness or pressure in the ears.Otoscope showed tympanic membrane invagination, scattered or disappeared cone of light, tympanic membrane was pale and dull.

[Treatment of pyriform sinus carcinoma involving the lateral wall].

Objective: To present and discuss the clinical features, treatment, and efficacy of pyriform sinus carcinoma involving the lateral wall.

Methods: Seventy-seven patients with pyriform sinus cancer involving the lateral wall (stage I 8, stage II 10, stage III 32, stage IV 27, according to UICC 2002 staging) were treated from Jun 1997 to Jun 2009 in the department of otorhinolaryngology head and neck surgery, Yuhuangding Hospital. The patients were divided into two groups: Group one 17 cases, simply underwent radiation therapy (R group); Group two 60 cases underwent surgery plus postoperative radiation (SR group).

[Surgery and function reconstruction of laryngeal cancer involved supraglottic and glottis area].

Objective: To investigate the surgery preserving epiglottis, the repair and the postoperative functions in laryngeal carcinoma involving supraglottic and glottic areas.

Methods: A total of 97 cases with laryngeal cancer involving both supraglottic and glottic areas with normal epiglottis underwent surgery between June 2005 and December 2010 was reviewed. Of them 37 cases were stage II, 41 cases were stage III, and 19 cases were stage IV.

[Resection and one-stage repair of basal cell carcinoma of external nose].

Objective: To present the method of resection and one-stage repair of basal cell carcinoma of external nose.

Methods: Sixty-two patients with basal cell carcinoma of external nose were hospitalized and underwent surgeries from January 2002 to June 2010. The defects after resection were as follows: 1 partial defect of soft tissue of lateral ala nasi, associated defect of ala nasi margin, total defect of ala nasi, defect of soft tissue of apex nasi, defect of apex nasi and ala nasi, defect of the bridge of the nose.

[Repairing of palatum durum defects following maxillectomy using nasal septum tissue flap].

Objective: To discuss the effect of repairing of palatum durum defects following maxillectomy using nasal septum tissue flap.

Methods: Twenty-six patients underwent maxillectomy and the defects were repaired by using full (16 cases) and partial (10 cases) nasal septum tissue flaps.

Results: Twenty-one patients were healed by first intention, recovering swallowing and pronunciation function.
