LA improved learning and memory abilities, superoxide dismutase (SOD) level, and form and number of Nissl bodies, while reduced the levels of Aβ , phosphorylated-tau (p-tau), reactive oxygen species (ROS), malondialdehyde (MDA), monoamine oxidase-B (MAO-B), histological injury, and apoptosis rate in AD group (P<0.05, P<0.01 or P<0.001). The anti-AD mechanism of LA may be related to RAS/MEK/ERK and other signaling pathways, in which the expressions of RAS/MEK/ERK signaling pathway-related proteins significantly reduced (P<0.05 or P<0.01). LA could improve the cognitive ability and reduce the pathologic impairment in AD mice, which might be partly mediated via inhibition of RAS/MEK/ERK singling pathway.

To report on our institution's first year of experience with a preferred vendor program for implants and disposables for sports medicine surgery. Cost and utilization data for implants and disposables were analyzed for knee and shoulder sports medicine surgeries performed during the 2-year period including the 12 months preceding the start of the contract (contract year 0 [CY0] and the first 12 months of the contract period (CY1). The costs of grafts and biological therapies were excluded. Utilization of the preferred vendor's products, operative time, and per-case costs were compared between the 2 time periods and adjusted for patient factors and case mix. Utilization of the preferred vendor's shavers (0% to 94%, P < .001) and radiofrequency ablation wands (0% to 91%, P < .001) increased significantly in CY1 (n= 5,068 cases) compared with CY0 (n= 5,409 cases), with a small but significant increase in use of the preferred vendor's implants (64% to 67%, P= .023). There was no significant difference in mean operative time between CY0 and CY1 (P= .485). Mean total per-case implant and disposable costs decreased by 12% (P < .001) in CY1 versus CY0. Our institution was able to reduce the costs of sports medicine surgery with the implementation of a preferred single-vendor program for implants and disposables. This program had widespread surgeon adoption and did not have any detrimental effect on operating room efficiency. III, retrospective comparative study. III, retrospective comparative study. To determine whether curettage of the cartilage on the glenoid edge in arthroscopic Bankart repair reduces the postoperative recurrence rate compared with noncuretted glenoid. Between January 2010 and December 2013, 134 patients underwent arthroscopy and stabilization for recurrent anterior dislocation of shoulder; 42 patients were excluded. Alternate glenoid edge was curetted in 92 patients undergoing arthroscopic Bankart repair. Twelve patients were lost to follow-up. The remaining 80 patients were divided into 2 groups of 40 patients each, curettage and noncurettage. In both groups, the Bankart lesion was repaired using ≥3 bioanchors loaded with nonabsorbable braided sutures. Postoperative rehabilitation was the same for the 2 groups. We recorded recurrence of instability, pain, and Constant and Rowe shoulder scores. Statistical analysis of data was performed using unpaired t test (significance level P<.05). The 2 groups were comparable in terms of age, number of dislocations, and bone loss. The average follow-up was 7 years and 9 months (range 6 to 10 years). Of the total 40 patients in the curettage group, 6 (15%) had recurrence of dislocation and none had subluxations, whereas in the noncurettage group, 13 (32.5%) had recurrence of dislocation and 3 (7.5%) had subluxations. The difference in postoperative recurrence of instability was statistically significant (P= .012). The average (standard deviation) Rowe score was 83.75 (23.28) in
