Purpose: To investigate the changes in salivary function and oral health-related quality of life for patients with nasopharyngeal carcinoma treated by intensity-modulated radiotherapy (IMRT).
Methods And Materials: A total of 57 patients with early-stage nasopharyngeal carcinoma received IMRT. The parotid and whole saliva flow was measured, and the Medical Outcomes Study 36-item short form, European Organization for Research and Treatment of Cancer Quality of Life questionnaire-C30, European Organization for Research and Treatment of Cancer Quality of Life questionnaire 35-item head-and-neck module, and Oral Health Impact Profile questionnaires were completed at baseline and 2, 6, 12, 18, and 24 months after IMRT.
Results: Parotid saliva flow recovered fully after 1 year and maintained. Whole saliva flow recovered partially to 40% of baseline. A general trend of deterioration in most quality of life scales was observed after IMRT, followed by gradual recovery. Persistent oral-related symptoms were found 2 years after treatment.
Conclusion: IMRT for early-stage nasopharyngeal carcinoma could only partially preserve the whole salivary function and oral health-related quality of life.

The Women's Health Care Committee was established in 2010 to improve the health of women. In the current academic year, this committee established seven subcommittees aimed at understanding diseases related to various age groups of women, including adolescence, sexual maturity, and menopause, and promoting research to improve the quality of life. Additionally, socially significant research has focused on infections, particularly resistant bacteria.

Background: Chronic lingual tonsillitis (CLT) entails persistent inflammation of the lingual tonsils (LT), presenting in recurrent infections, throat discomfort, dyspnea, dysphagia, and LT hypertrophy.
Methods: A retrospective observational study at a nonacademic general hospital described outcomes of CLT patients undergoing base of tongue (BOT) reduction via transoral robotic surgery (TORS). Primary outcomes were changes in patient-reported quality of swallowing and life and were assessed at baseline, 3, 6, and 12 months post-TORS.

Background: Locoregional external beam radiotherapy (EBRT) is selectively used in thyroid cancer patients to induce locoregional control. However, despite technological advances, EBRT remains associated with toxicities. We evaluated thyroid-cancer specific toxicities and long-term Quality of Life (QoL) post-EBRT.

Background: Women and sexual minority individuals have been found to be at higher risk for experiencing poor sleep health compared to their counterparts. However, research on the sleep health of sexual minority women (SMW) is lacking in China.
Objective: This study aimed to examine sleep quality and social support for Chinese women with varied sexual identities, and then investigate the in-depth relationships between sexual identity and sleep.
LC-MS/MS-based metabolomic study provides insights into altitude-dependent variations in flavonoid profiles of strawberries.

Environmental conditions significantly influence the metabolic composition and quality attributes of fruits. This study investigated the impact of altitude-associated environmental variation on flavonoid profiles and fruit quality parameters by comparing the "Red Face" strawberry variety grown in two distinct locations: high-altitude-associated environmental conditions in Zhaotong and low-altitude conditions in Dandong. Using LC-MS/MS analysis, we identified 163 bioactive flavonoids, comprising 85 flavonols, 37 flavanones, 33 flavones, and 8 flavanonols.
