Particulate matter 2.5 (PM2.5) may aggravate dry eye disease (DED). Corni Fructus (CF), which is fruit of Cornus officinalis Sieb. et Zucc., has been reported to have various beneficial pharmacological effects, whereas the effect of CF on the eye is still unknown. Therefore, in this study, we investigated the effect of oral administration of water extract of CF (CFW) on the eye, hematology, and biochemistry in a DED model induced by topical exposure to PM2.5. Furthermore, the efficacy of CFW compared with cyclosporine (CsA), an anti-inflammatory agent, and lutein, the posterior eye-protective agent. Sprague-Dawley rats were topically administered 5 mg/mL PM2.5 in both eyes four times daily for 14 days. During the same period, CFW (200 mg/kg and 400 mg/kg) and lutein (4.1 mg/kg) were orally administered once a day. All eyes of rats in the 0.05% cyclosporine A (CsA)-treated group were topically exposed to 20 μL of CsA, twice daily for 14 days. Oral administration of CFW attenuated the PM2.5-induced reduction of tear secretion and corneal epithelial damage. In addition, CFW protected against goblet cell loss in conjunctiva and overexpression of inflammatory factors in the lacrimal gland following topical exposure to PM2.5. Furthermore, CFW markedly prevented PM2.5-induced ganglion cell loss and recovered the thickness of inner plexiform layer. Meanwhile, CFW treatment decreased the levels of total cholesterol and low-density lipoprotein cholesterol in serum induced by PM2.5. Importantly, the efficacy of CFW was superior or similar to that of CsA and lutein. Taken together, oral administration of CFW may have protective effects against PM2.5-induced DED symptoms via stabilization of the tear film and suppression of inflammation. Furthermore, CFW may in part contribute to improving retinal function and lipid metabolism disorder.

Introduction: Particulate matter 2.5 (PM 2.5 ) are airborne particles small enough to be inhaled into the pulmonary alveoli, and are associated with increased hospitalization rates, morbidity, and mortality. The purpose of this study was to evaluate the levels of PM 2.5 in southeastern Louisiana and describe associated cardiovascular outcomes in patients with a history of myocardial infarction (MI). Methods: Air quality monitoring stations were placed around southeastern Louisiana and were analyzed from March 1 st , 2019 to March 1 st , 2020. Samples were collected every 80 seconds, and values were aggregated at the hourly and daily level. We used conditional logistic regression models to determine the risk of MI. Control observations per patient were created using PM 2.5 exposure on the same day of the week for the two weeks before and after the event. Temperature, pressure, humidity, and their interactions with PM 2.5 were included in the model. Results: The average PM 2.5 exposure for the year was 10.41 ug/m 3 +/- 5.57 ug/m 3 , with a daily low of 1.93 ug/m 3 and a daily high of 31.32 ug/m 3 . Peaks from individual sensors reached PM 2.5 concentrations greater than 100 ug/m 3 . PM 2.5 concentration showed a significant, weakly positive correlation with daily average temperature and a significant, weakly negative correlation with daily average barometric pressure. Among patients (n=263) with history of MI, risk of subsequent MI increased by 24.3% per 10 ug/m 3 increase in PM 2.5 exposure with a lag of three days after exposure. (Figure) No significant risk associated with PM 2.5 exposure was observed at shorter lag times. Conclusion: Although the average PM 2.5 levels in southeastern Louisiana were within the WHO guidelines of air quality, PM 2.5 exposure remained a significant risk factor for MI among a those with previous MI.
