Objective To probe the clinical character,the histopathological classification and misdiagnoses of intraocular tumors. Methods The clinical and pathological data of 359 patients with intraocular tumor diagnosed clinically between 1980～2000 were retrospectively analyzed. Results There were 300 cases of malignant tumor and 23 cases of benign tumor respectively. Non oncologic malady and benign tumor misdiagnosed as tumor or malignant tumor were 40 cases. The two leading malignant tumors were retinoblastoma and melanoma. Conclusion The clinical and pathological analysis of intraocular tumor is beneficial to the correct clinical diagnosis and treatment.

{L-End}Objective To explore the chain mediating effect of team psychological safety atmosphere and professional calling in the relationship between humble leadership and voice behavior. {L-End}Methods A total of 812 nurses from five medical institutions in Guangdong Province were selected as the research subjects using the convenience sampling method. The Team Psychological Safety Atmosphere Scale, the Professional Calling Scale, the Hospital Version of Humble Leadership Scale and the Voice Behavior Scale were used to investigate the perceived team psychological safety atmosphere and sense of professional calling, the perceived humble leadership style and voice behavior of the nurses. {L-End}Results The score of team psychological safety atmosphere, professional calling, humble leadership, and voice behavior of 812 nurses was (58.0±7.6), (44.6±8.0), (50.4±9.2) and (37.0±5.9), respectively, with the scoring rate of 72.5%, 74.3%, 80.0%, and 74.0%, respectively. Bootstrap analysis showed that humble leadership could positively influence voice behavior ［standardized effect value (β)=0.28, 95% confidence interval (CI) 0.20-0.35］. Humble leadership could influence voice behavior through the separate mediating effects of team psychological safety atmosphere (β=0.13, 95%CI 0.09-0.18), professional calling (β=0.07, 95%CI 0.04-0.11), and the chain mediating effect of team psychological safety atmosphere and professional calling(β=0.06, 95%CI 0.04-0.08). {L-End}Conclusion The voice behavior of clinical nurses is at a moderately high level. Humble leadership can directly influence voice behavior and can influence voice behavior through the mediating effects of team psychological safety atmosphere and professional calling. Nursing managers can inspire the work passion of clinical nurses by changing their own leadership style and creating a good atmosphere for voicing opinions.

Objective To analyze the current situation and latent profiles of nurses'voice behavior in nurses,and explore the influencing factors of different types.Methods Through convenience sampling,812 nurses who worked in tertiary hospitals from 5 cities in Guangdong Province during April 2022 to June 2022 were recruited.The demographic questionnaire,the Voice Behavior Scale,the Humble Leadership Scale,and the Team Psychological Safety Climate Scale were used for investigation.Latent profile analysis was used to explore the latent profiles of nurses'voice behavior.The influencing factors of latent profiles were identified by multivariate Logistic regression.Results The total score of the voice behavior in 812 nurses is(37.04±5.88).Voice behaviors in nurses is divided into 3 latent classes,namely"conservation group"(27.83％),"balanced-risky group"(61.95％),and"the challenge group"(10.22％).The influencing factors include recruitment type,whether to assist in department management,humble leadership,team psychological safety climate(all P＜0.05).Conclusion The level of nurses'voice behavior is upper medium with heterogeneity,which can be divided into 3 latent profiles.Nurses managers should focus on nurses with conservation group and balanced-risky group and conduct early targeted prevention and care according to characteristics and influencing factors of different latent profile.
