[Randomized Controlled Study on the Improvement of Community Residents' Mental Health Literacy Through Online Popular Science Program].

Objective: To explore the effects of online mental health promotion intervention consisting of popular science articles and short videos on the level of mental health literacy (MHL), the MHL competency rate, and depression and anxiety levels of local residents. Methods: Local residents in Shanghai were recruited for the study and assigned to a control group ( n=53) and a study group ( n=53) with a random number table. The study group participated in a 12-session mental health promotion intervention program that was carried out over the course of 4 weeks, while the control group did not receive any intervention. The subjects were assessed for their MHL, depression and anxiety by questionnaire surveys at the baseline (T1), after intervention (T2), and three months after intervention (T3). Results: At T2, there was significant difference in the rate of MHL competency between the study group (43.40%) and the control group (18.87%) ( P=0.006). There was no significant difference between the two groups at T1 ( P=0.787) or T3 ( P=0.840). The results of repeated measures analysis of variance of the total score of the MHL Questionnaire showed that the interaction effect was statistically significant ( F=9.708, P<0.001), the simple effect of grouping was statistically significant at T2 ( F=10.935, P=0.001), and the total score of MHL of the study group (134.321±20.123) was significantly higher than that of the control group (123.811±20.224) for the corresponding point of time. The simple effect of time in the study group was statistically significant ( F=23.233, P<0.001). The subjects in the study group scored significantly higher at T2 and T3 than they did at T1, or the baseline ( P<0.001). There was no significant difference between the T2 and the T3 scores ( P=0.847). Conclusion: The 12-session online mental health promotion intervention can effectively improve the subjects' MHL level and the rate of MHL competency immediately after the invention was completed, and the effect endures 3 months after intervention.

[The remove of intraocular foreign body by the assistance of the injection of silicone oil].

OBJECTIVE: To evaluate the effect of the injection of silicone oil in helping the remove of intraocular foreign body throughout pars plana vitrectomy (PPV). METHODS: It was a series case study. This study included 17 eyes with intraocular foreign body from June 2007 to April 2008. Intraocular foreign bodies in these eyes were hardly removed, and all of the eyes had complicated and severe retinal injuries. The intraocular foreign bodies were taken out followed intravitreal injection of silicon oil. The retinal protective effects of silicon oil were studied. RESULTS: All the intraocular foreign bodies were removed successfully without any damage to the retina due to the viscosity of silicon oil and its gasket function. CONCLUSIONS: Intravitreal injection of silicon oil was able to help the removement of hardly-hold intraocular foreign body with PPV and avoid secondary retinal injury in this process.
