Effects of ultrasound-guided alveolar recruitment manoeuvres compared with sustained inflation or no recruitment manoeuvres on atelectasis in laparoscopic gynaecological surgery as assessed by ultrasonography: a randomized clinical trial.

Background: The majority of patients may experience atelectasis under general anesthesia, and the Trendelenburg position and pneumoperitoneum can aggravate atelectasis during laparoscopic surgery, which promotes postoperative pulmonary complications. Lung recruitment manoeuvres have been proven to reduce perioperative atelectasis, but it remains controversial which method is optimal. Ultrasonic imaging can be conducive to confirming the effect of lung recruitment manoeuvres.

Androgen receptor reverts dexamethasone‑induced inhibition of prostate cancer cell proliferation and migration.

The aim of the present study was to determine the role of androgen receptor in the effect of dexamethasone on cell proliferation and migration of multiple prostate cancer cells. The prostate cancer cell lines LNCaP, 22Rv1, C4‑2 and PC3 were cultured in vitro. For glucocorticoid‑induced experiments, the cells were transferred and cultured in RPMI‑1640 medium with 10% charcoal‑stripped serum from RPMI‑1640 medium with 10% fetal bovine serum for at least 24 h.
