OBJECTIVETo investigate the correlation between age and Gleason score (GS) in patients with prostate adenocarcinoma.

METHODSThis study included 674 patients with pathologically confirmed prostate adenocarcinoma. We determined the GS, primary grade, and secondary grade of the cases, and compared them among different age groups.

RESULTSThe mean age of the patients was (70.22 ± 8.26) yr, ranging from 25 to 96 years, (69.06 ± 8.35) yr in those with GS 6, (70.55 ± 8.16) yr in GS 7, (70.99 ± 6.54) yr in GS 8, (71.56 ± 9.18) yr in GS 9, and (72.79 ± 11.36) in GS 10. The mean GS, primary grade, and secondary grade were 7.08 ± 1.09, 3.54 ± 0.72, and 3.53 ± 0.66, respectively, and the mean GSs in the < 60 yr, 60-69 yr, 70-79 yr, and ≥ 80 yr groups were 6.86 ± 1.10, 6.99 ± 1.10, 7.08 ± 1.04, and 7.38 ± 1.23, respectively. Those with GS 6, 7, and ≥ 8 accounted for 37.7%, 34.3%, and 28.0%, respectively. The patients aged < 60, 60-69, 70-79, and ≥ 80 years constituted 10.5% (71/674), 30.6% (206/674), 47.6% (321/674), and 11.3% (76/674), respectively. The age of the patients was significantly correlated with GS (r2 = 0.013, P = 0.003) and the primary grade (r2 = 0.014, P = 0.002), but not the secondary grade (r2 = 0.005, P = 0.055).

CONCLUSIONOf the prostate adenocarcinoma patients, those aged ≥ 70 years form a larger proportion, and those with GS ≥ 7 comprise a higher percentage. The age of the patient is correlated with Gleason score but has a limited value in its prediction.

OBJECTIVETo explore the basic features of the prostate carcinoma Gleason grading system of the International Society of Urological Pathology (ISUP).

METHODSWe analyzed the means and proportions of the Gleason score (GS), primary grade (PG), secondary grade (SG) and third grade (TG) of 667 cases of prostate carcinoma.

RESULTSThe means of GS, PG, SG and TG were 7.06 +/- 1.10, 3.53 +/- 0.66, 3.53 +/- 0.72 and 4.30 +/- 0.96, respectively. The cases with GS 5, 6, 7, 8, 9 and 10 accounted for 0.4% (3/677), 37.2% (252/677), 34.4% (233/677), 13.7% (93/677), 12.0% (81/677) and 2.2% (15/677), respectively; those with GS < or = 6 and > or = 7 constituted 37.7% (255/677) and 62.3% (422/677); those with GS3 + 3, 4 + 3 and 3 + 4 made up 37.2% (252/677), 19.2% (130/677) and 15.2% (103/677); and the TG cases held 10.3% (70/677), including 30.0% (21/70) of grade 3, 10% (7/70) of grade 4 and 60.0% (42/70) of grade 5.

CONCLUSIONOur study showed a high proportion of GS, a low proportion of GS < or = 6, and a high proportion of GS > or = 7 in the ISUP prostate carcinoma Gleason grading system. TG of GS needs to be further understood.

Objective To explore the efficient way to purify and to enrich umbilical cord mesenchymal stem cells which have abilities to differentiate into chondrocytes. Methods Umbilical cord was acquired from new born infants and chopped into 1 mm2 cubics, then they were pretreated with colleganase and trypsin so as to get the mixed cell suspension. CD45(-),CD90(+) cells were acquired from the mixed cell suspension via FCM sorting and were cultured in the medium as umbilical cord mesenchymal stem PO cells. The PO cells were detached and passaged by multiplex collagenase NB4 and the positive rate of CD90 and CD45 of the P1-P3 cells were observeed via FCM ; the P3 cells were induced to differentiated into chondrocytes. Results FCM results showed that the positive rate of CD90 on P1, P2, F3 was (80.86 ± 7.85)%,(95.86± 3.28)%,(97.15± 1.43)%, while the positive rate of CD45 on P1, P2, P3 cells was (2.53 ±0.28)% and (0.97 ± 0.48)% and (0.05 ± 0.01)% respectively; P3 cells had differenciated into chondrocytes. Conclusion FCM presorting and Multiplex collagenase detachment procedures can swiftly acquire highly purified human umbilical cord mesenchymal stem cells which have the ability to differentiate into chondroeytes.

Objective To observe the effect of Sachet-therapy on prevention of infant upper respiratory tract infection. Methods A cluster sampling was conducted for quantitative investigation. Hangzhou urban infants were randomly treated with either wearing Sachet or not wearing Sachet for 12 weeks′ observation.We then analyzed statistically the incidence of the two groups. Results The incidence was 14.42 % in the infant observer group and 54.98% in the contrast group with statistical significance(P

AIMTo investigate the effects of the recombina nt human endostatin on adjuvant arthritis (AA) in rats and its mechanisms. METHODSThe model of rat AA was induced by injection of intradermal CFA. ConA and LPS induce d splencytes proliferation was examined by MTT asssy and the activities of inter leukin-1 (IL-1) and IL-2 were measured by the method of thymocytes prolifera tion. Synoviocytes were dispersed with incubation of collagenase and trypsin, an d IL-1, TNF production of synoviocytes was estimated with radio-immunity assay . RESULTSThe secondary inflammation of AA rats appeared on the 1 0th day after injection of CFA. The therapeutic administration of endostatin (0 1, 0 5, 2 5 mg?kg -1 ?d -1 , sc, ?7 d) was given at that time(d 10). It was found that endostatin significantly inhibited the secondary paw swel ling. The increased ConA-induced splenic lymphocyte proliferation reaction and the activated IL-1 and IL-2 activity of AA rats was reversed by the treatment with endostatin. Meanwhile,IL-1 produced by PM? was increased. Endostatin inh ibited IL-1 production from PM? and IL-1 and reduced TNF level of Synoviocyte s in AA rats. CONCLUSIONThe recombinant human endostatin has the rapeutical effect on AA rats, its mechanisms is related to its immunoregulative function.

Objective To evaluate the feasibility of bladder extracellular matrix (BACM) seeding with autologous cultured vaginal smooth muscle cells (VSMC) repaired rabbit vaginal defect.Methods This study included 24 female rabbits.BACM and vaginal acellular matrix (VACM) were obtained from 8 rabbits by decellularization process.The other 16 rabbits were randomly divided into experimental and control groups.Vaginal tissue biopsies ( ～ 1 cm2) were harvested from female New Zealand rabbits.VSMC were cultured and stained with a-smooth muscle actin antibodies. Cultured VSMC cells were seeded on BACM ( experimental group) or VACM ( control group) at a cell density of 1 × 107 cells/cm2.The cell-seeded matrixes were cultured for 5days.In experimental group of 8 rabbits,a 2 cm segment of vagina was resected and replaced with BACM seeding with VSMC.Then the regenerative segment was studied with histological technique by hematoxylin-eosin staining after 3,6 and 12 weeks postoperative aud vaginography was performed at 12 weeks postoperative.The 8 rabbits in control group underwent the exact same procedure as above but the vaginal defect was repaired with VACM seeding with VSMC,Results The prepared BACM and VACM were transparent,HE staining and scanning electron microscopy showed the two acellular matrix was both consisted of abundant network of fibers with the regular arrangement,without cellular debris.Primary culture of VSMC was successfully established and passaged,and was uniformly spindle-shaped in the confluent state and showed a characteristic hill and valley'formation.Immunohistochemical staining showed VSMC in culture stained positively with a-smooth muscle actin antibodies.VSMC began to adhere to the BACM 5 hour after implanting and the number of the adhered cells increased with time.Cells gradually expanded and showed the typical morphology of smooth muscle cells.Three weeks after implantation in vivo,the luminal surface of matrix was completely covered by vaginal epithelial tissue,a layer of smooth muscle cells was formed in the outer surface of the matrix.Multilayered vaginal epithelial and improved development of organized muscle bundles was observed after 6 weeks.The regenerative tissue was equivalent to the normal vaginal tissue at 12 weeks postoperatively.Vaginography demonstrated the maintenance of full patency and a wide vaginal caliber without fibrosis and graft rejection.There was no significant difference in all evaluated items between experimental and control groups.Conclusions BACM has the same regenerative process as VACM in the replacement of vaginal defect.Moreover,BACM has wider source and appears to be an suitable material for vaginal replacement.
