Evaluation of the long-term effect of foldable capsular vitreous bodies in severe ocular rupture.

Aim: To evaluate the long-term effect of foldable capsular vitreous body (FCVB) in the treatment of severe ocular rupture to provide a practical basis for clinical selection.

Methods: A total of 26 patients (26 eyes), 23 men and 3 women, with severe ocular rupture who underwent FCVB implantation between March 2018 and September 2018 were retrospectively analysed. All open ocular wounds located in zone III, with preoperative visual acuity grade IV and above (Snellen less than 4/200).

[Health Benefit Assessment of PM Pollution Control in Beijing].

The assessment of residents' health and economic benefits of PM pollution control is of great significance for the promotion of regional environmental air pollution monitoring, warning, and prevention. This paper utilized Poisson regression relative risk models and environmental value assessment methods to assess the health risks and economic benefits of PM pollution control in the 16 municipal districts of Beijing from 2016 to 2019 after reaching the secondary standard limit of 35 μg·m. The results showed that PM concentrations, various health effects, economic benefits, and per capita economic health benefits in all 16 districts showed a downward trend.

Osseous Rosai-Dorfman disease of tibia in children: A case report.

Background: Rosai-Dorfman disease (RDD), or sinus histiocytosis with massive lymphadenopathy, is a benign histiocytic disorder. Extranodal involvement is common, occurring in > 40% of patients, but bone involvement occurs in < 10% of cases. In addition, primary bone RDD is extremely rare.

[Regulatory effects of ninjurin-1 on adhesion of myeloid cells in the retina at the early stage of diabetic rats].

Objective: To investigate the regulatory effects of ninjurin-1 on adhesion of myeloid cells in the retina at the early stage of diabetic rats.

Methods: Experimental study. The rat diabetic model was induced by intraperitoneal injection of streptozotocin.

[Change of plasma endothelin-1 concentrations in photodynamic induced rat anterior ischemic optic neuropathy model and drug modulation].

Objective: To investigate changes of plasma endothelin-1 (ET-1) concentration in photodynamic induced rat anterior ischemic optic neuropathy model (rAION) and evaluate the effects of compound anisodine hydrobromide (CA).

Methods: Eighty-five Sprague-Dawley (SD) male rats were randomly divided into a blank control group of 10 rats and a model group of 75 rats. rAION model was established in the model group by photodynamic induction.
