Pupil Diameter Changes after Anesthesia with Different Doses of Sufentanil under Ultrasound Monitoring.

Objective: This study aims to observe the changes in pupil diameter (PD) after anesthesia with different doses of sufentanil with the ultrasound method and observe whether pupil contraction is correlated with hemodynamic changes and bispectral index (BIS) values.

Methods: A total of 124 patients between the ages of 18-65 with ASA I-II undergoing general anesthesia for surgery were enrolled in the study. According to the sufentanil dose initially injected, they were randomly divided into groups P, S1, S2, and S3, with 31 cases in each group.

Two new bioactive polyphenols from the soft coral-derived fungus sp. SCSIO 041201.

Two new polyphenols, talaversatilis A () and B (), together with fifteen known compounds (-) were isolated from the extract of the culture broth of a soft coral-derived fungus sp. SCSIO 041201. The structures of these compounds were elucidated by the extensive analyses of spectroscopic data and by comparison with the reported literature.
