Article Synopsis
- 3'-Daidzein sulfonate sodium (DSS), a water-soluble compound from daidzein, is studied for its potential neuroprotective effects against hippocampal damage and memory impairment.
- Rat models with chronic cerebral hypoperfusion were treated with varying doses of DSS for five weeks, and tests including the Morris water maze and TUNEL assay showed that DSS significantly improved learning and memory, reduced neuron apoptosis, and enhanced key signaling proteins in the hippocampus.
- The results suggest that DSS may offer protection against memory deficits and brain damage by activating the PKA/ERK1/2/CREB signaling pathway.

Objective: To compare the diagnostic value of blind double-lumen plugged telescoping catheter (PTC) and protected specimen brush(PSB) in patients requiring mechanical ventilation (MV) for suspected ventilation-associated pneunonia (VAP).
Methods: Sixty-nine patients with a hospital stay of >/= 48 h who required MV for suspicion of VAP were prospectively enrolled in the study during Jan 2008 and Feb 2009 in the medical intensive care unit. The patients all underwent bronchial samplings: a blind PTC and a fiberoptic PSB were performed successively in each case.
