To evaluate the efficacy and safety of limbal relaxing incision ( LRl) for correcting corneal astigmatism during implantable collamer lens ( lCL) surgery.METHODS:A total of 185 eyes of 105 patients with high myopia and corneal keratometric astigmatism were included in the study. lCL surgery with concomitant relaxing incision was performed in 105 eyes of 60 patients in LRls group ( Group A) . Eighty eyes of 45 patients only underwent lCL surgery were in control group ( Group B) . All patients undergone ophthalmic examination that included uncorrected visual acuity ( UCVA ) , best -corrected visual acuity ( BCVA ) , Pentacam analysis system to observe the changes of corneal astigmatism before and 1wk, 1 and 3mo after surgery.RESULTS: Respectively comparing UCVA between two groups in 1 and 3mo postoperatively, the P values were considered statistically significant ( P < 0. 05 ). But, respectively comparing BCVA between two groups in 1wk, 1 and 3mo postoperatively, the P values were considered no statistically significant ( P > 0. 05 ). Preoperative corneal astigmatism was 1. 52 ± 0. 55D in group A and 1. 48 ± 0. 57D in group B, there was no statistically significant difference (P>0. 05). One week postoperatively, the astigmatism was 0. 55 ± 0. 41D in group A and 1. 20 ± 0. 48D in group B. One month postoperatively, the astigmatism was 0. 60 ± 0. 38D in group A and 0. 93 ± 0. 47D. Three months postoperatively, the astigmatism was 0. 51 ± 0. 32D in group A and 0. 96 ± 0. 40D in group B. The difference between the two groups were statistically significant ( P<0. 05 ). The difference value of corned astigmatism before surgery and 1wk, 1 and 3mo after surgery had statistical significance ( P<0. 05). ln LRls group, at preoperative and postoperative time points, the average corneal astigmatism changes were also considered statistically significant difference (P<0. 05). CONCLUSlON: LRls performed during lCL surgery appeared to be an effective and safer procedure to reduce pre-existing corneal astigmatism and improve UCVA as well as the visual quality.

OBJECTIVE:
To observe the changes of malondialdehyde (MDA), superoxide dismutase (SOD), tumor necrosis factor-alpha (TNF-alpha), and interleukin-1beta (IL-1beta) in rat brain tissue and to explore the mechanism of secondary cerebral injury after brain concussion.
METHODS:
The brain concussion model was established with the pathological changes of rat brain tissue by Weil stain. The expressions of MDA and SOD in brain tissue were examined by photochemical method. The expressions of TNF-alpha and IL-1beta in cerebral cortex and hippocampus were examined by immunochemistry.
RESULTS:
Nerve myelin sheath showed disorder, disruption, gryposis and swelling by Weil stain. Above changes were more severe at 12h. The quantity of MDA in rat brain tissue after concussion was significantly higher than that in the control group. The activity of SOD was significantly lower than that in the control group. The expressions of TNF-alpha and IL-1beta increased more significantly in cerebral cortex and hippocampus in rat brain tissue after concussion than that in the control group.
CONCLUSION
Oxidative stress and inflammatory injury in the rat brain tissue, which may play an important role in secondary cerebral injury after concussion.

Objective To observe the relationship of awake bispectral index (BISawake) and the postoperative cognitive dysfunction (POCD). Methods 100 patients aged 60~75 years with ASA status Ⅰ~Ⅱ, underwent elective lower abdominal surgery with intravenous anesthesia (propofol, remifentanyl and rocuronium). The BIS was adjusted in 40~60 during the surgery. Their cognitive function was assessed with the neuropsychological test battery commended by International study of postoperative cognitive dysfunction (ISPOCD). Results 8 patients withdrew for unwilling or serious complications. The BISawake was more than 65 in 68 patients (group A), and less than 65 in 24 patients (group B). The difference of the verbal learning immediate and delayed of Hopkins Verbal Learning Test-Revised was more in the group B than in the group A. Conclusion Lower BISawake may be associated with the decline of postoperative cognitive function.
