Abstract: One aspect relates to a composition for predicting preterm birth of the pregnant woman comprising an agent for detecting microorganisms of at least one genus selected from the group consisting of the genus Ureaplasma and the genus Prevotella and microorganisms of the genus Lactobacillus in a vaginal fluid sample of the pregnant woman and a method for predicting preterm birth using the same. According to one aspect, if the relative abundance ratio of the detected microorganisms of at least one genus selected from the group consisting of the genus Ureaplasma and the genus Prevotella is higher than that of normal pregnant woman, and the relative abundance ratio of the detected microorganisms of the genus Lactobacillus is lower than that of normal pregnant woman, it is predicted that preterm birth will occur. Therefore, the composition can be usefully used to predict preterm birth in pregnant women.

Abstract: The present invention relates to treatment of dry eye syndrome using a tanfanercept-containing ophthalmic composition. According to the present invention, as a result of clinical trial on dry eye syndrome, the tanfanercept-containing ophthalmic composition demonstrated excellent effects with regard to improvement of a central corneal staining score (CCSS) and a total corneal staining score (TCSS), which is clinically important. Further, such improvement of a central corneal staining score (CCSS) and a total corneal staining score (TCSS) was more significantly demonstrated in the patients with moderate-to-severe severity of dry eye. In addition, the patients with higher ocular discomfort score or higher eye dryness score, which are subjective symptoms, also showed greater improvement. Even though the same dose of tanfanercept was used, the tanfanercept-containing ophthalmic composition showed superior efficacy in the patient having more serious or severe baseline sign or symptom scores.
