Objective To investigate the correlation of clinical stage and treatment plan with prognosis in incidental prostatic carcinoma.Methods From 2004 to 2010,a total of 1076 patients diagnosed as BPH underwent transurethral plasma kinetic enucleation of prostate (TUPKEP) in our hospital,and their clinical data were respectively analyzed.Among them,42 cases were found to have incidental prostatic carcinoma.The correlation of clinical stage and treatment plan with prognosis in incidental prostatic carcinoma were observed.Results Among 1076 BPH patients undergoing TUPKEP operation,42 cases (3.9％) aged 56-88 years were found to have incidental prostatic carcinoma,which all displayed as prostatic adenocarcinoma including 18 cases at T1 a stage and 24 cases at T1b stage.10 cases received endocrinal therapy,14 cases received bilateral orchiectomy,14 cases underwent radical prostectomy and 4 cases were treated with watchful waiting.Patients were followed up for 24 to 96 months.The survival rates were 100.0％ and the rates of progression were 0.0％,20.0％,0.0％ in T1 a patients received watchful waiting,androgen-deprivation therapy and radical prostectomy,respectively.Total survival rate was 100.0％ and total rate of progression was 11.1％ in T1a patients.The survival rates were 71.4％,100.0％ and the rates of progression were 42.9％,0.0％ in T1 b patients received androgen-deprivation therapy and radical prostectomy,respectively.Total survival rate was 83.3 ％ and total rate of progression was 25.0 ％ in T1 b patients.Compared with T1 b patients,the total survival rate was higher (x2=18.19,P＜0.01) and the rate of progression was lower in T1 a patients (x2 =6.52,P＜0.05).Conclusions The survival rate in T1 a patients accepted androgen-deprivation therapy is similar to that in T1 a patients with watchful waiting.Compared with T1a patients,the survival rate is lower but the rate of progression is higher in T1 b patients received active androgen-deprivation therapy.The survival rate is higher in T1 b patients treated with radical prostectomy than in those received other treatments.Watchful waiting is acceptable for T1 a patients.T1 b patients should be treated with radical prostectomy for a better effect.

Background The ubiquitin-proteasome pathway(UPP)involves 80%-90% degradation of all in- tracellular proteins.Both ubiquitin and rat component 3 of proteasome(RC3)are hence considered to be central me- diators for cell biology.Objective To evaluate the effect of simvastatin on neointimal hyperplasia and the expres- sion of ubiquitin and rat component 3 of proteasome(RC3)after balloon injury in carotid artery.Methods Thirty- two male SD rats were randomly to receive,low dose(0.4 mg/ng,n=8),or moderate(4 mg/ng,n=8),or high- dose(40 mg/ng,n=8)of simvastatin treatment for 28 days.Common carotid aortic artery was injuried rat ballon. The ratio of intima-media(I/M)thickness was determined.The expression level of ubiquitin and RC3 mRNA were assessed by RT-PCR.The expression level of ubiquitin protein was examined with immunohistochemistry. Results Simvastatin inhibited the expression of ubiquitin and RC3 mRNA and ubiquitin protein in dose dependent manner.The intima-media ratio(-50.2 %)and the expression of ubiquitin(-60.3 %)and RC3 mRNA and ubiq- uitin protein(-60.5 %)was reduced by the high dose simvastatin [40 mg/(kg?d)](P

Objective To compare the clinical efficacy and safety between transurethral plasma kinetic enucleation of prostate(TUPKEP) and transurethral resection of prostate(TURP) on benign prostatic hyperplasia(BPH). Methods One hundred and forty two BPH patients were divided into two groups:TUPKEP group (72 cases) and TURP group (70 cases). Seventy two cases aged 52-90 years[mean age (70. 5±7.6) years] with prostate weight of 27-126 g [mean weight (75. 6±10. 3)g] underwent TUPKEP, and seventy cases aged 51-87 years[mean age (70. 2±6. 8) years] with prostate weight of 25-118 g[mean weight (73.8±9.9)g] underwent TURP. There were no significant differences in age, weight of the prostate, international prostate symptom score(IPSS), residual urine volume(RUV) ,maximum urinary flow rate (Qmax) and quality of life (QOL) scores between the two groups before operation (t=0. 2873, 1.0612, 1. 0832,0. 9522,0. 0000, 1. 0774;P=0. 7743,0. 2904, 0. 2806,0. 3426,1. 0000,0. 2832). The operative time, intraoperative blood loss, the preserved time of installing catheter, hospitalization time, postoperative morbidity rate and efficacy were compared between the two groups. Results The operation success rates were 100. 0% (72/72) in TUPKEP group and 98.6% (69/70) in TURP group. The average operation time were (46.2±6.4)min and (58. 4±9. 6)min (t±8. 9404, P=0.0000), and the mean intraoperative blood loss were (105.9± 12.2)ml and (148.6±14.3) ml(t=19. 1608, P=0.0000) in TUPKEP and TURP groups respectively. The mean preserved time of installing catheter were (3. 5±1.0)d and (5.0±1.0)d(t= 8. 9364, P=0. 0000), and the average hospitalization time were (5.1±1.9) d and (7.0±2.6) d (t= 4. 9819,P=0.0000)in the two groups, respectively. In TUPKEP group, there was one case of temporary urinary incontinence, two cases of secondary prostate hemorrhage and one case of external orifice stricture of urethra, with a complication rate of 5.56%. In TURP group, there were two cases of transurethral resection syndrome (TURS), one case of urinary extravasation, two cases of temporary urinary incontinence, three cases of secondary prostate hemorrhage and two cases of external orifice stricture of urethra, with a complication rate of 14.29% . Compared with preoperation, Qmax was obviously increased and IPSS,RUV, QOL scores were decreased after follow- up for 3 months, but there were no significant differences in these parameters between the two conditions(t=1. 1131,0. 2543,1. 2959,0. 7252;P=0. 2676,0. 7996,0. 1971,0. 4696). Canclusions TUPKEP and TURP have similar efficacy in the treatment of BPH, but TUPKEP is a method with shorter operation time, less blood loss, lower postoperative complication rate and more safety than TURP.

Objective To investigate the risk factors and treatment of postoperative delirium in patients with benign prostatic hyperplasia(BPH). Methods　For 256 postoperrative BPH patients in our department,the clinical parameters including age,hypoxemia,preoperative infection,postoperative pain,and introvert were analyzed,and the treatment were summarized. Results　The incidence of postoperative delirium was higher in patients aged≥75 years than＜75 years[17.4%(19/109)vs.5.4%(8/147),X2=8.307,P=0.0043,higher in patients with preoperative infection (pulmonary or urinary)versus without the infection[15.0%(17/113)vs.7.0%(10/143),X2=4.337,P=0.037],higher in patients with hypoxia versus without hipoxia[16.5%(16/97).vs.6.9%(111159),X2=4.885,P=0.027]and higher in patients with post-operative pain versus without the pain(16.9%(10/59)vs.1.2%(1/85),X2=10.146,P=0.0014].Hematocrit and hemoglobin in patients with postoperative delirium were lower after operation versus pre-operation[(0.29±0.04)vs.(0.42±0.04),t=12.2314,P＜0.001;(102.39±6.58)g/L vs.(114.58±8.36)g/L,t=5.9537,P＜0.001].All delirium patients were recovered after sedation treatment,improving the quality of sleep,controlling the infection and correcting electrolyte turbulence. Conclusions　Advanced age,hypoxemia,preoperative infection,postoperative pain are important risk factors for delirium.

OBJECTIVETo investigate the association of A260G and A386G polymorphisms of the DAZL gene with male infertility caused by oligozoospermia or azoospermia.

METHODSWe searched the PubMed, Science Direct, Wiley Online Library, CNKI, VIP, and CDDB databases up to November 30, 2013 for case-control studies evaluating the relationship of SNP260 and SNP386 polymorphisms of the DAZL gene with male infertility, and meanwhile conducted manual sourcing of the references in the identified studies and relevant articles. Two reviewers independently screened the title, abstract and keywords of each article retrieved. The StataSE12. 0 software was used for meta-analysis and other statistical analyses.

RESULTSTotally, 13 case-control studies were included (10 about A260G and 11 about A386G), involving 2 715 infertile patients (2 500 with oligozoospermia or azoospermia) and 1 835 normozoospermic men. DAZL A260G showed no statistical significance in the allele, dominant, recessive, co-dominant, or super-dominant gene model (P >0. 05). DAZL A386G exhibited a strong correlation with oligozoospermia or azoospermia in Asians in the allele gene model (OR = 0. 15, 95% CI 0.07 -0.34, P <0.05), dominant gene model (OR =0. 16, 95% CI 0.07 - 0. 35, P <0.05), co-dominant gene model (AA/AG) (OR = 0. 15, 95% CI 0. 06 - 0. 33, P < 0. 05), and super-dominant gene model (OR = 0. 15 (95% CI 0.06 - 0.33, P <0.05) , and so did it in Chinese in the four gene models ( OR = 0. 11, 95% CI 0.04 - 0. 28, P <0.05; OR =0. 11, 95% CI 0.04 - 0.28, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P<0.05; OR = 0.09, 95% CI 0.03 - 0.26, P< 0.05).

CONCLUSIONOur study manifested that the DAZL polymorphism A386G, but not A260G, was correlated with reduced sper- matogenesis or sperm count specifically in Chinese males. More high-quality trials are required for a deeper insight into the exact relationship of DAZL A260G and A386G polymorphisms with oligozoospermia- or azoospermia-induced male infertility.

Objective To investigate the changes of brain volumes in neuromyelitis optica (NMO)patients using voxel-based morphometry (VBM) method, and preliminarily explore the pattern of cerebral anatomical impairment. Methods Twenty-three clinically defined NMO patients and 15 gender and age matched healthy volunteers underwent 3-dimensional (3D) fast spoiled gradient echo (FSPGR) sequence scanning on 3.0 Tesla MR systen. Raw data was processed and analyzed using statistical parametric mapping (SPM) 5. Whole brain volumes included grey matter volume (GMV), white matter volume (WMV), total intracranial volume (TIV), grey matter fraction (GMF), white matter fraction (WMF),brain tissue fraction (BTF) and regional brain volumes between the two groups were compared by independent samples t-test and an Pearson were performed to compare the regional brain volumes and the ages. Results GMV of NMO group[(610. 2 ± 55.0) ml] was significantly decreased comparing to healthy control group[(657. 2 ± 36. 3) ml] (t = - 2. 915, P ＜ 0. 05). The age of NMO patients [(40 ± 9) years old] showed negative correlation with GMF [(42. 5 ± 2. 6) %] (r = - 0. 673, P ＜ 0. 05). Regional brain volume analysis showed decreased GMV in left insula and bilateral posterior cingutates in NMO patients,while decreased WMV was found in left frontal and left parietal white matter. Conclusion VBM could detect brain volume changes sensitively. Total grey matter volume in NMO patients was decreased comparing to HC group. Regional grey matter atrophy in NMO patients occurred in left insular and bilateral posterior cingutates, regional white matter atrophy occurred in left frontal and left parietal lobe.

Objective To examine the association of urinary neutrophil gelatinase-associated lipocalin(NGAL) and interleukin 18(IL-18) with acute kidney injury (AKI) in patients after cardiac surgery. Methods Thirty-three patients undergone cardiac surgery were divided into AKI group and non-AKI group according to the AKI criteria. The Scr, urinary NGAL and IL-18 were measured at different time points. Results Nine of 33 patients (27.27%)developed postoperative AKI, and Scr concentration in AKI group reached its peak within 12-48 hours after cardiac surgery. Urinary concentrations of NGAL and IL-18 at 2 h and 4 h after cardiac surgery were significantly higher than those before operation in AKI patients (P<0.01). The urinary concentrations of NGAL at each time point and that of IL-18 at 2 h and 4 h after cardiac surgery in AKI patients were significantly higher than those in non-AKI patients. After correction by urinary creatinine, the differences of NGAL/Ucr and IL-18/Ucr ratios were still significant (P< 0.01). For concentrations of urinary NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after surgery, sensitivities and specificities were good with cutoff values at 250 μg/L, 250 μg/mmol and 1800 ng/L, 1800 ng/mmol, respectively. Urinary concentration of NGAL at 2 h after cardiac surgery was positively correlated with Scr at 12 h postoperation in AKI group (r=0.638, P<0.05).Conclusions The incidence of AKI in patients after cardiac surgery is quite high. Urinary concentrations of NGAL, IL-18 and ratios of NGAL/Ucr, IL-18/Ucr at 2 h after cardiac surgery are the early diagnostic markers for AKI, among which urinary NGAL/Ucr is the most sensitive one.
