Factors influencing willingness to participate in ophthalmic clinical trials and strategies for effective recruitment.

Aim: To explore the factors influencing individuals' willingness to participate in ophthalmic clinical trials.

Methods: A questionnaire survey was conducted from January to April 2021 among patients and their family members at Zhongshan Ophthalmic Center, Sun Yat-sen University, in Guangzhou, China. The survey gathered data on respondents' willingness, demographic and socioeconomic profiles, as well as their reasons and concerns regarding engagement in clinical trials.

[Heat-sensitive moxibustion of different suspension moxibustion methods and imitation moxibustion apparatus on moxibustion sensation and clinical efficacy in knee osteoarthritis].

Objective: To observe the moxibustion sensation and the clinical therapeutic effect of heat-sensitive moxibustion of two different suspension moxibustion methods and imitation moxibustion apparatus on mild to moderate knee osteoarthritis (KOA), and compare the therapeutic effect of different moxibustion methods.

Methods: A total of 90 patients with mild to moderate KOA were randomized into a hand-held group (30 cases, 1 case dropped off), an imitation moxibustion apparatus group (30 cases) and a moxibustion shelf group (30 cases, 1 case dropped off). point, Dubi (ST 35), Neixiyan (EX-LE 4), Yanglingquan (GB 34), Yinlingquan (SP 9), Liangqiu (ST 34) and Xuehai (SP 10) were selected as the frequent acupoint areas to explore and determine the heat-sensitive acupoints, after that, hand-held suspension moxibustion, suspension moxibustion with imitation moxibustion apparatus and suspension moxibustion with moxibustion shelf were adopted in the 3 groups respectively.

[Distribution and source apportionment of polycyclic aromatic hydrocarbons (PAHs) in urban rainfall runoff].

Runoff samples were collected from traffic roads, campus, residential road and roof in a typical rain event. Polycyclic aromatic hydrocarbons (PAHs) in both dissolved and particle phases were investigated at impervious surfaces. The PAHs wash-off process at different monitoring sites was analyzed.
