OBJECTIVETo investigate the clinical manifestations, pathological characteristics, and treatments of urothelial-type mucinous adenocarcinoma of the prostate (UMAP).
METHODSWe reported a case of UMAP, reviewed relevant literature, and analyzed the clinicopaothological features, diagnosis, treatment, and prognosis of the disease.
RESULTSThe patient was a 60-year-old male and underwent transurethral resection of the prostate for dysuria. Postoperative pathology indicated mucinous adenocarcinoma and sigmoidoscopy revealed no primary colon cancer. Immunohistochemical staining showed the negative expressions of PSA and P504s and positive expressions of CK7, CK34 β E12, CK20, and CDX2. Thus UMAP was confirmed and treated by intensity-modulated radiotherapy. Then the patient was followed up for 30 months, which showed desirable therapeutic result, with neither local progression nor distant metastasis.
CONCLUSIONUMAP has a bad prognosis and its diagnosis depends on pathological and immunohistocchemical examinations. It responds well to radical prostatectomy but is not sensitive to endocrine therapy. Radiotherapy can be considered for those who are not fit to receive radical prostatectomy.

Objective To study the effect of platelet-derived growth factor(PDGF)and lysosomes on lung injury in macaque with early-phase endotoxie shock.Method Eleven macaques were randomly divided into two groups,namely,control group(Co group,n=5)iand endotoxic group(En group,n=6).The macaque of the Co group injected with 1 ml/kg normal saline and the macque of the En group received a dose of 2.8 mg/kg Lipopolysaccharides(LPS)i.v.The blood gas was detected at 120 minutes after LPS challenging. Uhrastructure,cytochemistry of acid phosphatase(ACPase)detection by electronic microscopy and immunohistochemical assay of PDGF were completed in hmgs of all the macaque .Results Administration of LPS did not change the parameters of gas exchange,namely,PaO_2,PaO_2/Fi and PaCO_2.In the early phase,of endotoxic shock,ACPase activity products increased and lysosome destroyed in the alveolar cells.The pathologic changes of alveolus,such as degeneration of vessel endothelium,injury of alveolar epithelium and damage of basement membrane,and transudation of blood component were observed by electron microscopy in the En group. However,no pathological changes were found in the control group.By immunohistochemical staining,PDGF on alveolar wall in the En animals was observed,whereas no PDGF protein in the Co macaques was noticed. Conclusions Administration of LPS induced the expression of PDGF in the alveolar wall and lysosome injury in the alveolar cells,as a result of alveolar damage in early-phase endotoxin shock.In the meantime,the parameters of gas exchanges did not change.The PDGF may play an important role in the pathogenesis of lung during the early-phase of endotoxin shock.

The present study was aimed to explore the expressions of transforming growth factor-β1 (TGF-β1) and Snail1 in renal tissues of diabetic rats, and their role in tubular epithelial-mesenchymal transition (TEMT). Induced diabetic rats were randomly divided into 2-, 4-, 8-, 12-, 16-, 20-, 24-week and 16wA, 20wA, 24wA groups. The rats in 16wA, 20wA and 24wA groups were treated with insulin to control blood glucose to the normal level from the 13th week. The age-matched rats were set as controls. Blood glucose, 24-hour urine protein, serum creatinine (Scr), kidney index of rats were measured. PAS staining was used to observe the renal pathological changes. Immunohistochemical staining and (or) Western blot were employed to determine the expressions of TGF-β1, Snail1, E-cadherin, α-smooth muscle actin (α-SMA) and fibronectin (FN) proteins. The expressions of Snail1 and E-cadherin mRNAs in renal cortex were examined by RT-PCR. Blood glucose, 24-hour urine protein, Scr and kidney index increased remarkably in diabetic rats as compared with those in the control groups (P<0.05, P<0.01) and insulin-treated rats (P<0.01). TGF-β1 and Snail1 protein expressions could not be detected by immunohistochemical staining in the normal renal tissues, however, the strongly positive staining was observed in diabetic rat renal tubules. A time-dependent loss of TGF-β1 and Snail1 expressions was detected in the kidney of insulin-treated rats. In diabetic rats tubular α-SMA positive staining was seen at the 16th week. E-cadherin expression was lost in diabetic rats. The expressions of TGF-β1, Snail1 proteins and Snail1 mRNA were significantly up-regulated in diabetic rats, while down-regulated in insulin-treated rats (P<0.01). The expressions of E-cadherin protein and mRNA in the cortex were contrary to the expressions of TGF-β1 and Snail1. Therefore, TGF-β1 and Snail1 are possibly involved in the pathogenesis of TEMT in diabetic nephropathy rats.

The aim of the present study was to investigate the role of p38 MAPK in the renal tubular epithelial-mesenchymal transition (TEMT) induced by high glucose. In in vivo study, the rats were randomly divided into control (C), diabetes mellitus (DM) and insulin-treated DM groups. Immunohistochemical staining and Western blot were employed to determine the expression of p38 MAPK and p-p38 MAPK protein in renal cortex of rats. In in vitro study, primary renal tubular epithelial cells (PTECs) were cultured with normal glucose (5.5 mmol/L), high glucose (20 mmol/L D-glucose), high osmolality (20 mmol/L D-mannitol) and SB202190 (a p38 MAPK inhibitor) plus high glucose respectively for 72 h. The expressions of p38 MAPK, p-p38 MAPK, Snail1, transforming growth factor-beta1 (TGF-beta1), alpha-smooth muscle actin (alpha-SMA) and E-cadherin protein and mRNA were detected by immunocytochemical staining, Western blot and RT-PCR. The p38 MAPK and p-p38 MAPK were specifically upregulated by high glucose in both in vivo and in vitro studies. The p38 MAPK activation was abolished by insulin controlling hyperglycemia to normal level in DM rats and inhibited dramatically by SB202190 in high glucose-cultured PTECs. The protein and mRNA of alpha-SMA were markedly increased in PTECs cultured with high glucose and were 12-fold and 8-fold respectively over that in the normal glucose, which were significantly suppressed by SB202190. SB202190 down-regulated the high glucose-induced Snail1 protein expression in PETCs, and restored partly the depression of E-cadherin protein and mRNA. These results suggest that p38 MAPK mediates high glucose-induced TEMT via transcription factor Snail1.

The aim of this study was to investigate effects of IAT and MAT chemotherapeutic regimens treating patients with refractory and relapsed acute myeloid leukemia (AML). 99 patients with refractory and relapsed AML received IAT regimen or MAT regimen as study objects were retrospectively analyzed (56 patients with refractory AML and 43 patients with relapsed AML). Among of them, 28 patients were treated with IAT regimen, and 71 patients received with MAT regimen. The results showed that in 2 groups mentioned above the OR was 65.7%, CR was 49.5%, PR was 16.2%; in IAT group the OR was 64.3%, CR was 46.4%; in MAT group the OR was 66.2%, CR was 50.7%, no statistical difference was found between these 2 groups; The 2 years overall survival was 25% in IAT group and 15.5% in MAT group. Serious infection in IAT and MAT regime groups was 25% and 9.9%, respectively. It is concluded that both IAT and MAT regimens are effective methods for inducing CR in patients with refractory of relapsed AML. IAT and MAT regimens can be used in treatment of the refractory or relapsed MAL patients who were not respond to other regimen.

OBJECTIVETo investigate the protective effect of lycopene against cryopreservation injury of post-thawing human sperm and its mechanism.
METHODSSemen samples were collected from 25 volunteers, each sample equally divided into four parts to be cryopreserved with cryoprotectant only (Ly0 control) or cryoprotectant + lycopene at the concentrations of 2 (Ly2), 5 (Ly5), and 10 µmol/L (Ly10), respectively. Before and after thawing, the semen samples were subjected to computer-assisted semen analysis ( CASA) for sperm kinematics, flow cytometry for sperm apoptosis, thiobarbituric acid assay for malondialdehyde (MDA) concentration, and JC-1 fluorescent staining for the sperm mitochondrial membrane potential (MMP).
RESULTSAfter cryopreservation, sperm motility was markedly decreased in all the groups (P < 0.01). The rate of sperm apoptosis was significantly lower in the Ly5 group than in the Ly0 control ([25.68 ± 4.36]% vs [33.26 ± 4.78]%, P < 0.05), while sperm MMP remarkably higher in the former than in the latter ([66.18 ± 14.23]% vs [55.24 ± 12.31]%, P < 0.05). The Ly2, Ly5 and Ly10 groups showed no statistically significance differences in the MDA level from the Ly0 control (P > 0.05).
CONCLUSIONAddition of lycopene at a proper concentration to cryoprotectant may reduce oxidative damage to sperm mitochondria in the freezing-thawing process, attenuate oxidative stress injury induced by reactive oxygen species to sperm plasma membrane, and improve the anti-apoptosis ability of sperm.

OBJECTIVESTo investigate the difference of BPH incidence in two groups.
METHODS309 cadres and 314 farmers over 60 years old in district of Wannan have been investigated. The investigation included prostate volume (V), IPSS, L, Qmax, residual urine (R) and dietary constituents.
RESULTSThe intake of animal protein in cadres is more than that in farmers (u = 24.10, P < 0.01), and the incidence rate of BPH is significantly higher (91.1% vs 11.8%, chi 2 = 24.64, P < 0.001). Logistic regression shows that the intake of animal protein has a parallel relationship with BPH.
CONCLUSIONSIn the district of Wannan, the incidence of BPH in cadres is significantly higher than that of farmers, and it may be correlated with the amount of animal protein intake.
