BackgroundDue to the prominent particularity of medical work， nurses are prone to developing depression， which not only poses a considerable threat to the physical and mental health of nurses， but also affects the quality of nursing to some extent. Occupational stress is a known contributor to depression in nurses， whereas relatively little research has been done to investigate the underlying mediation path.ObjectiveTo explore the mediation effect of perceived organizational support and psychological capital on the relationship between occupational stress and depression among nurses， and to provide theoretical references for the prevention and treatment of occupational stress-induced depression in nurses.MethodsFrom March to August 2019， a stratified random sampling method was utilized to select a sample size of 720 nurses in each department of a grade A tertiary hospital in Shandong Province. All subjects were assessed using Effort-Reward Imbalance Questionnaire （ERI）， Perceived Organization Support Questionnaire （POS）， Psychological Capital Questionnaire （PCQ） and Center for Epidemiologic Studies Depression Scale （CES-D）. Pearson correlation was adopted to examine the correlation among above scales， and multilevel mediation analyses were conducted with model 6 in Process macro （version 3.3） for SPSS 26.0 using Bootstrap re-sampling method.ResultsA total of 658 nurses （91.39%） completed the effective questionnaire survey. ERI score was positively correlated with CES-D score （r=0.499， P

Objective To investigate the clinical efficacy and effects of periodontal endoscope (PE)-assisted subgingival scaling and root planning (SRP) and traditional SRP on the psychological and quality of life of patients with periodontitis. Methods This study was reviewed and approved by the Ethics Committee, and informed consent was obtained from the patients. Patients with periodontitis who were treated in the Department of Periodontology, Nanjing Stomatological Hospital, Medical School of Nanjing University from April 2018 to December 2022 with residual periodontal pockets (PD ≥ 5 mm) 6 weeks after traditional SRP treatment were enrolled, and the residual periodontal pockets were further treated with PE-assisted SRP (PE+SRP). After 6 weeks of traditional SRP treatment and 3 months of PE+SRP treatment, clinical indicators, including plaque index (PLI), probing depth (PD), clinical attachment loss (CAL) and bleeding on probing (BOP), were measured, and periodontal tissue self-awareness scale scores, oral health impact profile-14 (OHIP-14) score and dental fear scale (DFS) score were collected. Moreover, visual analog scale (VAS) scores were collected after traditional SRP and PE-assisted SRP treatments. Results Twenty-three patients with periodontitis, including 832 sites of 486 affected teeth, were included in the clinical study. Three months after PE+SRP treatment, all clinical periodontal indicators, PLI (t = 9.254, P

ObjectiveTo understand the current status of primary healthcare workers’ knowledge of hepatitis B and their willingness to engage in non-discriminatory behaviors， to explore the factors influencing their willingness， and to provide a basis for health education on hepatitis B for primary healthcare workers in Qinghai Province.MethodsA questionnaire survey was conducted among primary healthcare institutions in eight cities （prefectures） of Qinghai Province using a combination of random sampling and convenience sampling. The questionnaire included demographic information， knowledge related to hepatitis B， and willingness to engage in non-discriminatory behaviors.ResultsA total of 393 subjects were included in the survey. The accurate awareness rate of hepatitis B transmission route among primary healthcare workers in Qinghai Province was 36.89%. Of the respondents， 46.31% were unwilling to live with family members infected with HBV or carriers， and 50.13% were unwilling to dine with friends infected with HBV or carriers. The willingness of primary healthcare workers to engage in non-discriminatory behaviors related to hepatitis B varied by different places of residence， gender， marital status and per capita household income （P

ObjectiveTo analyze the online public Q&A texts on HPV vaccine， focus on the important issues related to HPV vaccination and cervical cancer prevention in China， and propose strategies and suggestions.MethodsThe latent Dirichlet allocation （LDA） topic model was employed to extract key topics of 15 565 Q&A texts related to HPV vaccines from the social Q&A platform "Zhihu". The Baidu AI sentiment analysis tool was used to analyze the emotional tendencies of the texts corresponding to each topic， and the topics were classified based on the strategic coordinate method.ResultsOnline users focused on eight topics about HPV vaccine information. Among them， vaccination knowledge， HPV vaccination hesitation， and HPV vaccine development and marketing belonged to the low positivity-high negativity emotional topics， HPV infection and high-risk factors belonged to the low positivity-low negativity emotional topics， and HPV vaccine appointment channels， comparison between domestic and imported vaccines， HPV vaccines and cervical cancer prevention， and HPV vaccine types and selection were grouped under high positivity-low negativity emotional topics.ConclusionPublic concerns regarding HPV vaccines can be classified into three major dimensions： health knowledge， health beliefs， and health behaviors. Overall， the public's views and attitudes towards vaccine-related issues are not optimistic. Strengthening science publicity and education， enhancing vaccine supervision， and encouraging enterprises’ innovative research and development capability are effective strategies to improve public awareness of cervical cancer prevention and accelerate the full HPV vaccination coverage.
