This article discussed the roles of surgery, brain radiation, chemotherapy, targeted therapy , and other new directions in the treatment of patients with brain metastases from NSCLC.

Purpose To study the prevalence and feature of EGR gene rearrangement in prostatic carcinoma. Methods 242 consecu-tive core biopsies of prostatic carcinoma were evaluated. All biopsy specimens contained 6-14 cores from left and right sides separately delivered. The patient age ranged 58 to 91 years, and PSA value 5 ng/ml to more than 5 000 ng/ml. Immunohistochemistry ( IHC) for ERG protein overexpression and fluorescent in situ hybridization ( FISH) for ERG gene rearrangement were performed. Results 42 cases were detected positive for ERG by IHC ( positive rate 17. 4%) , and positive for ERG rearrangement by FISH either, with 19 ca-ses showing fusion through deletion and 23 through insertion, while no negative cases by IHC demonstrated positive by FISH. 5 cases revealed positive and negative staining in different carcinoma foci of ERG. No ERG positive staining and rearrangement were found in adjacent benign glands. Of positive cases, 12 cases were graded as Gleason score 6, 23 Gleason score 7, and 7 Gleason score 8 or more. Positive rate was 19. 6% in the group of PSA value less than 100 ng/ml, and 10% of more than 100 ng/ml, whereas 17. 2% in the group of clinical T3 stage or less, and 19% of clinical T4 and lymph node or remote metastasis. ERG rearrangement was associated with lower Gleason score, but not with PSA value, clinical stage and progression using theχ2 test analysis. Conclusions IHC is relia-ble for detection ERG rearrangement and helpful for interpretation of prostatic carcinoma. Multiple foci are common in prostatic carcino-ma. There is no significance between ERG rearrangement and disease prognosis.

Preoperative PSA value, Gleason Score of biopsy, involved core number by cancer is a still helpful parameter for clinical staging and risk estimate.

Objective To analyze the protein expression changes of retina in diabetic mice using isobaric tags for relative and absolute quantitation (iTRAQ) approach and to study proteins of apoptosis.Methods 8 diabetic mice were chosen as the diabetic model group (DM group),8diabetic mice as the normal control group.The animals were housed in wire-bottomed cages and received normal pellet chow and tap water in a constant environment.After 10 weeks,all mice were killed,and their retina were dissected.After hematoxylin and eosin(H&E) staining,the sections of retina were examined using light microscopy.The changes of protein expression in retina were studied using iTRAQ approach.Expression of apoptosis associated proteins was analyzed using ingenuity pathway analysis (IPA).Results Compared with control group,mice retina in DM group developed looser structures,tissue edema and obvious telangiectasia under light microscopy.Using iTRAQ approach,a total of 348 differential proteins were identified.Among those proteins,16 proteins were related with apoptosis,including Ataxin-10,Protein NDRG1,mucin-4,Aquaporin-1 and annexin A4,etc.There were 8 apoptosis-related proteins in retina with up-regulation,and the other 8 proteins with down-regulation in the DM group.The relationship between these proteins were analyzed and charted by IPA.Conclusions Apoptosis may be involved in the development of diabetic retinopathy.The identification of the apoptosis-related proteins will be helpful for the further study.

A simple and efficient method for the determination of organotin compounds ( OTCs) in biota by GC-MS coupling with sodium tetraethylborate ( NaBEt4 ) derivatization was established. The results showed that recoveries for each OTCs spiked in blank freeze-dryed biological samples ( 0 . 1 g ) following extraction (15 mL 0. 035 mol/L methanolic HCl solution for 1 h ) and derivatization (2 mL contained internal standard n-hexane and 0. 5 mL of 2% (m/V) NaBEt4 solution for 30 min) were above 80%. The method is fast and easy to operate for the determination of OTCs in complex biological samples. The minimum limit of detection was about 0. 01 μg/L, and relative standard deviation values were within 10% for three parallel samples.
