Objective To investigate the effect of erythropoietin (EPO) on the expression of MMP-2 in hippocampus of neonatal rats after hypoxic-ischemic brain damage (HIBD), and the mechanism of its neuroprotective effect. Methods Neonatal Sprague-Dawley rats of 7 days old were randomly divided into three groups (n?=?48 in each group): sham-operated group, HIBD group and EPO treated group, then each group was further divided into four subgroups (n?=?12) based on different time points following the injection of medication ( 6 h, 24 h, 3 d, 7 d). The expression of MMP-2 in hippocampus was determined by immunohistochemistry and real-time lfuorescent quantitative PCR method. Results Immunohistochemistry: MMP-2 has a small amount of expression in the hippocampus of the sham-operated group, and at each time point, there is no statistically signiifcant difference (P?>?0.05);The expression of MMP-2 in HIBD group and EPO group all show a trend of increase, and peaked at 7 d, the differences between each time point in two groups are statistically signiifcant (P?0.05);Compared with control group, the difference in each time point of the other two groups showed signiifcance (P?0.05) in addition to the 6 h point, and there is signiifcant difference at the 7 d point between EPO group and HIBD group (P?0.05). RT-qPCR:The gene expression of MMP-2 in control group presents a trend of increase, but there is no signiifcant difference at different time points (P?>?0.05). Gene expression in HIBD group at 24 h and 7 d points showed twin peaks, and the peak is higher at the 7 d point, but without difference (P?>?0.05). MMP-2 expression of EPO group presents a trend of increase, and differences are signiifcant between each time point (P?0.05);At each time point, the expression of MMP-2 mRNA in both HIBD group and EPO group is extremely high than that in sham-operated group (P<0.05). Compared with the HIBD group, the expression of MMP-2 mRNA at 24 h of EPO group decreased, but it is signiifcantly higher at the time of 7 d (P?0.05). Conclusion Erythropoietin may upregulate the expression of MMP-2 in the delayed phase of HIBD, which may be one of the mechanisms for protecting HIBD.

Purpose To study clinicopathologic feature of prostate cancer by complete embedding of radical prostatectomy specimen. Methods 108 cases of radical prostatectomy by systematic whole organ embedding were reviewed. Results The patient age ranged from 55 to 80 years ( mean 68. 1 years) . The preoperative average PSA value was 18. 3μg/ml. 59 cases ( accounting for 54. 6% of all prostatectomy cases) were in pT2 stage, while 23. 7% (14/59) in pT2a stage, 8. 5% (5/59) in pT2b, and 67. 8% (40/59) in pT2c. 49 cases (45. 4%)in pT3 stage, while 59. 2% (29/49) in pT3a, 40. 8% (20/49) in pT3b. 3. 6%(3/84)cases presented pelvic lymph node metastasis. 8. 3% (9/108) cases were graded as Gleason Score 6 or less, 61. 1% Gleason Score 7, 30. 6%(33/108)Gleason Score 8 or more. Gleason Pattern 5 component was found in 26. 9% (29/108) cases. Positive margin was observed in 25. 9% (28/108) cases, with 75% (21/28) in pT3 stage and 53. 6% (15/28) having Gleason Pattern 5. Patient in pT2 stage pres-ented mean PSA value of 14. 00 μg/ml, involved in no more than 2 biopsy cores in 68. 5% cases, and more than 5 cores in 4. 3%, while in pT3 stage, presented mean PSA value of 23. 82μg/ml, involved in no more than 2 cores in 19. 6%, and more than 5 cores in 28. 3%. The difference of involved core number was significant in pT2 and pT3 tumors ( P<0. 01 ) . 81. 3% cases graded Gleason Score 6 in biopsy was assigned to Gleason Score 7 or more in prostatectomy. Conclusions Completely sampling radical prostatectomy specimen should be recommended for accurate staging and margin status. Preoperative PSA value, Gleason Score of biopsy, involved core number by cancer is a still helpful parameter for clinical staging and risk estimate.

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.
