Women's knowledge, attitude, and practice regarding cervical precancerous lesions: a cross-sectional study in Beijing, China.

Background: This study aimed to examine the knowledge, attitude, and practice (KAP) of women in Beijing regarding cervical precancerous lesions.

Methods: This web-based, cross-sectional study included women at Dongzhimen Hospital of Beijing University of Chinese Medicine between March 13, 2024 and April 9, 2024. A self-administered questionnaire was developed to collect participants' demographic information and KAP scores toward cervical precancerous lesions.

Two-dimensional coordination polymers with high proton conductivity and ultrafast highly efficient molecular sieving constructed by the structural inductive effect.

A family of unique 2D-layered Cu-based coordination polymers (abbreviated as HNNU-1α, 1β and 1γ) with different halide anions were successfully constructed using a zwitterion pyridiniumolate as the structural inductive agent (SIA). More importantly, we found that the laminates of HNNU-1α exhibit ultrafast highly-efficient molecular sieving in a water system, and HNNU-1α to 1γ display a good proton conductivity of 2.2 × 10, 4.
