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.

Objective To investigate the applicative value of enhanced 3D multi-echo GRE T2*-weighted angiography(ESWAN) sequence phase values in evaluating brain gray nuclei iron content in idiopathic restless legs syndrome(RLS) patients, providing imaging basis in diagnosis and treatment of idiopathic RLS. Methods In our institute from June 2012 to September 2016,forty-five RLS patients were selected as the RLS group, and 45 healthy volunteers as the control group. ESWAN sequence was performed and serum ferritin values were obtained in all patients and volunteers. The raw data of ESWAN was postprocessed , where the phase maps were obtained. Phase analysis was performed on localized brain gray nuclei regions of interest (substantia nigra, red nucleus, dentate nucleus, thalamus, pallidum, putamen and caudate nucleus ) selected on phase maps. Differences between the 2 subject groups were evaluated using ANCOVA including age as a covariate. Results The phase values of the substantia nigra, thalamus, pallidum and putamen in the RLS group were (-0.087 ± 0.021), (-0.053 ± 0.012), (-0.161 ± 0.008), (-0.125 ± 0.019) radians , respectively. The phase values of the substantia nigra, thalamus, pallidum and putamen in the control group were (-0.127 ± 0.007), (-0.066 ± 0.007), (-0.166 ± 0.007), (-0.150 ± 0.010) radians, respectively. There were significant differences between the two groups (F=142.492, 37.988, 10.558, 60.725;P<0.05). Indicating reduced iron content in several regions of brain gray nuclei of the patients with RLS. Serum ferritin concentration between the RLS patients (157.02±95.78)μg/L and healthy controls (175.49 ± 38.65)μg/L was not significant (F=1.353,P>0.05). Conclusions Phase values can make a quantitative assessment of brain gray nuclei iron content in RLS patients, our results supported the hypothesis of reduced brain iron content in RLS patents , which may have an important role in the pathogenesis of the disorder. However, iron content change in some brain regions was not correlated with serum ferritin concentration changes.

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.

Objective: To analyse the composition of hospitalization childbirth costs and its influencing factors, which provides theory basis on reasonable control of rapid growth of hospitalization childbirth costs. Methods: With the method of stratified random sampling, 12 secondary and tertiary hospitals were chosen in Shanghai. According to the hospitalization number, the maternal disease cases delivering from Jan. 1, 2016 to Jun. 30, 2016 were randomly selected. The basic information and the cost of hospitalization were collected, and the database was established. Descriptive statistics, z test, non-parametric test and multiple linear stepwise regression analysis were performed by SPSS 20.0. Results: The cost of hospital delivery per capita in Shanghai from Jan. to Jun. 2016 was 7 826.39 yuan, of which the cost of bed, inspection, operation and western medicine accounted for the highest proportion of the expenses (17%, 16%, 15% and 15%, respectively). Maternal hospitalization cost univariate analysis showed that the effect of age, occupation, payment, pregnancy complications, modes of delivery, length of stay, prenatal and postnatal pathological condition on hospitalization cost were statistically significant. A multifactorial study on the cost of hospitalization showed that the delivery mode, length of stay, prenatal and postnatal pathological pathological condition, age and pregnancy complications were the main influencing factors. Conclusion: The hospitalization cost of cesarean section is significantly higher than that of vaginal delivery, the hospital cost structure of these two modes of delivery is different, and the reduction of cesarean section rate is of great significance. It is necessary to optimize the hospital cost structure via controlling the cost of western medicine, operation, and inspection.

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.

Objective To evaluate the effectiveness of transcatheter arterial chemoembolization(TACE) combined with radiofrequency ablation(RFA) and TACE combined with 125I interstitial brachytherapy in the treatment of primary hepatocellular carcinoma(HCC) and to compare the results of the two therapies.Methods Fifty patients with HCC underwent TACE and RFA during laparotomy and 34 patients received TACE and radioactive 125I particle seeding.Four weeks after the procedure,dynamic enhanced CT or MR scanning was performed for a check.If the lipiodol deposit was poor,TACE was repeated.Follow-up check was made at regular intervals to observe the results.Results One month after the treatment,the local control rate of the tumor for TACE +RFA and TACE + 125I particle seeding combination therapy was 98.0% and 97.1%,respectively.No statistically significant difference existed between the two therapies.Conclusions Both TACE combined with RFA or with 125I particle seeding are effective therapies for HCC,which can be regarded as an ideal alternative therapy for patients who have failed to respond to TACE alone.

Abstract: Objective　To screening new compounds that can inhibit the growth and biofilm formation of Staphylococcus aureus. Methods　Compounds that can inhibit the growth of Staphylococcus aureus were screened from the FDA approved drug library by 96 well plates. The absorbance value of 600 nm wavelength (OD600) was measured by Microplate Reader to detect the growth of Staphylococcus aureus planktonic cells in the culture supernatant. The minimum inhibitory concentration (MIC) of ozanimod against Staphylococcus aureus clinical isolates were detected by micro broth dilution method. The inhibitory effect of sub-inhibitory concentrations of ozanimod on the biofilm formation of Staphylococcus aureus was detected by crystal violet staining. Results　This study found that ozanimod could significantly inhibit the growth of Staphylococcus aureus SA113 (screening reference strain), and the MIC was 25.00 μmol/L. The MIC of ozanimod against 119 clinical isolates of Staphylococcus aureus [65 isolates of methicillin sensitive (MSSA) and 54 isolates of methicillin resistant (MRSA)] was 12.50 or 25.00 μmol/L. The MIC50 and MIC90 of ozanimod against the 119 Staphylococcus aureus isolates all were 25.00 μmol/L. This study found that 6.25, 12.50, 25.00 μmol/L of ozanimod could significantly inhibit the biofilm formation of 2 MSSA and 2 MRSA. The sub-MIC concentration of ozanimod (12.50 μmol/L) could significantly inhibit the biofilm formation of 14 MSSA and 11 MRSA, but had no inhibitory effect on the growth of planktonic cells of these Staphylococcus aureus isolates. Conclusion　Ozanimod can inhibit the growth of Staphylococcus aureus, including MRSA, and has good antibacterial activity. The sub-MIC concentration of ozanimod could significantly inhibit the biofilm formation of Staphylococcus aureus.
