Objective: This study reports on a translation of the Menstrual Symptom Questionnaire (MSQ) into Chinese, a cross-cultural adaptation among Chinese women of reproductive age, and an assessment of its reliability and validity.
Methods: Previously published translation guidelines were followed to translate and cross-culturally adapt the English version of MSQ to produce a Chinese version. This Chinese version was then administered to 2800 Chinese women of reproductive age recruited by convenience sampling method. The reliability of the Chinese MSQ was tested for internal consistency and test-retest reliability. The concurrent and construct validity of the questionnaire was evaluated using correlation and factor analysis.
Results: The Chinese version of the MSQ showed no linguistic or semantic issues. The internal consistency of the Chinese MSQ Cronbach'α = 0.912, and the test-retest reliability = 0.911. The exploratory factor analysis identified four factors. The confirmatory factor analysis demonstrated that the four factor structure of the Chinese version of the MSQ (Pain Experience, Emotional Changes, Pain Coping Strategies, and Other Physical Symptoms) is reasonable among Chinese women of reproductive age. There was a significant correlation found between these four factors and both the Pittsburgh Sleep Quality Index and the SF-8 Health Survey.
Conclusion: The Chinese version of the MSQ achieved semantic equivalence in translation and demonstrated good reliability and validity among Chinese women of reproductive age. Thus, it can serve as an effective tool to assess the experience of menstrual symptoms among Chinese women.

The attitudes of reproductive-age individuals toward COVID-19 vaccination during pregnancy are still not well understood. We aimed to explore the attitudes toward COVID-19 vaccines during pregnancy and the determinants among the Chinese reproductive-age population. An anonymous cross-sectional study was conducted in China from July 4 to August 11, 2023.

Aluminum-carbon nanotube (Al-CNT) composites represent a cutting-edge class of materials characterized by their exceptional mechanical, thermal, and electrical properties, making them highly promising for aerospace, automotive, electronics, and energy applications. This review systematically examines the impact of various fabrication methods, including conventional powder metallurgy, diffusion and reaction coupling, as well as adhesive and reaction bonding on the microstructure and performance of Al-CNT composites. The analysis emphasizes the critical role of CNT dispersion, interfacial bonding, and the formation of reinforcing phases, such as AlC and AlO, in determining the mechanical strength, wear resistance, corrosion resistance, and thermal stability of these materials.

Oily sensitive skin is complex and requires accurate identification and personalized care. However, the current classification method relies on subjective assessment. This study aimed to classify skin type and subtype using objective biophysical parameters to investigate differences in skin characteristics across anatomical and morphological regions.
