The diagnosis and treatment of prostate cancer are being improved due to the popularized screening of prostate specific antigen. Advanced prostate cancer, in spite of its response to androgen deprivation therapy, may finally develop into castration-resistant prostate cancer (CRPC) and shorten the overall survival of the patients. Many efforts have been made by worldwide researchers for new approaches to the management of CRPC, including new hormonal therapy, cytotoxic chemotherapy, immunotherapy, and bone metastasis-targeted therapy. This paper reviews the emerging agents undergoing clinical evaluation and drugs that have received approval for the treatment of CRPC in order to provide doctors and patients with more treatment options for CRPC and improve the overall survival rate and quality of life of the patients.

Objective To investigate the relevant risk factors for fungal infection following operation of the gastrointestinal neo- plasm and offer supporting data for the prevention of fungal infection.Methods Medical records from 116 patients who under- went the operation of gastrointestinal neoplasm in the special group of this hospital from January 2006 to June 2006 were retro- spectively reviewed on the relevant risk factors by univariate and multivariate Logistic regression analysis.Results Of the 116 patients reviewed, 18 had fungal infection.Forty-six samples were positive for fungal pathogen.The most frequently isolated fungal strain was Candida albicans (15/20) and the most common infection site was gastrointestinal tract (14/18).Fungal in- fection after the operation of gastrointestinal neoplasm was significantly relevant with the duration of antibiotic use, duration of post-operative fasting, low serum albumin, high blood glucose and complication of bacterial infection.The duration of antibiotic use was a significantly independent risk factor.Conclusions Reasonable antibiotic use, nutritional support, early enteral nutri- tion and control of blood glucose should be taken into account after the operation of gastrointestinal neoplasm in order to prevent fungal infections.

Objective To evaluate the b value of diffusion-weighted(DW)MRI in distinguishing between benign and malignant breast lesions.Methods Three diffusion-weighted sequences were implemented with 500,1000 and 2000 s/mm~2 b values respectively on 95 breast lesions in 83 patients.All lesions were confirmed by pathology.The apparent diffusion coefficient(ADC)values and signal intensity (SI)were recorded and compared in different lesions(breast cancer,benign lesion,cyst and normal beast tissue)with the same b value and the same lesions with the different b values.Results(1)The mean ADC value and SI of breast cancer were 1.375?0.378 and 839.713?360.493 respectively with b= 500 s/mm~2,1.176?0.311 and 459.314?229.609 with b=1000 s/mm~2,0.824?0.198 and 243.825? 110.616 with b=2000 s/mm~2.The differences in the mean ADC value were significant between two type lesions(cancer and benign lesion,cancer and cyst,cancer and normal breast tissue)with b values of 500 s/mm~2 and 1000 s/mm~2.But the significant differenee was only seen between cancer and benign lesions when b value was 2000 s/mm~2.(2)The one-side upper limits of 95% confidence interval of mean ADCs were adopted as the point to separate the malignant from the benign lesions,the sensitivity was 70.92%, 70.73% and 69.77%,the specificity was 77.19%,75.70% and 54.76%,the accuracy was 77.12%, 74.32% and 62.35% respectively with b values of 500 s/mm~2,1000 s/mm~2 and 2000 s/mm~2.The areas under ROC eurves were Az_(500)=0.775?0.046(P0.05).Conclusion DWI MRI is useful for the differential diagnosis of breast lesions with b values of 500 s/mm~2 and 1000 s/mm~2.

Objective To explore the relationship between fluconazole resistance and expression of multidrug resistant protein genes,including CDR1,CDR2,MDRI.Methods The total RNA was extracted from fluconazole-resistant and -susceptible Candida albicans isolates,and cDNA was synthesized.The expression of CDR1,CDR2 and MDRl genes was then detected by quantitative real-time PCR.The?CT (threshold cycle) value was obtained by subtracting the CT value of 18S rRNA from that of the targeted gene.Results The?CT value of CDR2 was significantly lower in fluconazole-resistant isolates than in fluconazole- susceptible isolates (7.52?2.53 vs.9.28?3.15,t=2.367,P

ObjectiveTo explore the role of BTBD10 overexpression in the proliferation of insulinoma cell line INS-1and its mechanism. MethodsThe recombined expression plasmid of pcDNA4.0-BTBD10 was constructed by gene cloning technique and was transfected into INS-1 cell by lipofectamine 2000. The stable overexpression BTBD10 of INS-1cell was selected at 48th hour after transfection.INS-1 cell proliferation activity was measured by MTT method.The expression of BTBD10,protein kinase B(Akt),phospho-Akt(p-Akt),mammal target of rapamycin (mTOR) and phospho-mTOR (p-mTOR) were determined by Western blot.ResultsThe stable overexpression BTBD10 of INS-1 cell wassuccessfullyconstructed.OverproductionofBTBD10promotedbetacellproliferation.The phosphorylation of Akt and mTOR was increased and the ratio of p-Akt/Akt and p-mTOR/mTOR was enhanced in the INS-1 overexpressed by BTBD10.But the expression of total Akt and mTOR presented no obvious changes. Conclusion The overexpression BTBD10 of INS-1 cell could activate of Akt/mTOR signalling pathway via stimulating phospho-mTOR and Akt,and enhance overall cell protein translation,so as to promote proliferation of INS-1 cell.

Objective To observe the effect of different analgesic methods including patient controlled epidural analgesia (PCEA) and patient controlled intravenous analgesia (PCIA) on stress response and anxiety in surgical patients with lower limb fracture. Methods A total of 120 surgical patients with lower limb fractures were employed and divided randomly into Groups PCEA, PCIA and C (40per group). All patients were anaesthetized by using combined spinal-epidural anesthesia. After operation, PCEA and PCIA were applied in the patients of Groups PCEA and PCIA, respectively. No analgesic method was employed in the Group C. The dynamic indices including mean blood press (MAP) and heart rate (HR), blood serum cortisol (COR) and blood sugar (BS) were measured at different time points,ie, T0 ( pre-anesthesia), T1 ( the end of the operation), T2 (24 hours after operation) and T3 (48 hours after operation). The visual analogue pain score was conducted at time points of T1, T2 and T3. The measurement of anxiety score was done at pre-operation and at days 1 and 7 after operation. Results There were no significant changes in HR and MAP of Groups PCEA and PCIA (P＞0.05, compared with T0) at every time point after operation. Whereas, HR and MAP of Group C were increased at time points of T1 and T2 (P ＜ 0.05, compared with T0 ), with statistical difference compared with Groups PCEA and PCIA at the same time points (P ＜ 0.05 ). VAS in Group PCEA was lower than that in Group PCIA at time points of T2 and T3 ( P ＜ 0.05). Meanwhile, VAS in Groups PCEA and PCIA was lower than that in Group C (P＜0. 05). COR and BS in Group PCEA were significant lower than those in group PCIA at time points of T2 and T3 (P ＜ 0. 05 ). Meanwhile, COR and BS in Groups PCEA and PCIA was lower than that in Group C (P＜0.05 or ＜0.01 ). Moreover, the changes were more significant in Group PCIA than that in Group PCEA (P ＜ 0. 05 ). The anxiety score in Groups PCEA and PCIA was lower than that in Group C (P ＜ 0.05). Conclusions Two analgesic methods of PCEA and PCIA can provide safe and effective postoperative analgesia and attenuate the stress response and anxiety in surgical patients with lower limb fracture. Meanwhile, PCEA takes more advantages than PCIA.

Objective To establish the in vivo models of adriamycin(ADR)-induced cardiotoxicity in rabbits, investigate the protective effect of oxymatrine (OMT) on ADR-induced cardiotoxicity, and explore the possible mechanism. Methods Twenty-six rabbits were randomly divided into ADR group (n=8, 2 mg/kg ADR), OMT group (n=5, 10 mg/kg OMT), ADR + OMT group (n=8, 10 mg/kg OMT was injected 30 min before ADR injection) and saline group (n=5, same quantity of normal saline), and rabbits in each group were infused with medicine or normal saline through ear marginal vein once a week for 8 weeks. The apoptosis of myocardial cells was detected by TUNEL methods, and the activity of superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) was determined. Results After treatment, the body weight of ADR group was significantly lower than that of the other groups(P < 0.05), the activity of SOD and GSH-Px significantly decreased and the apoptosis index (AI) was significantly higher than that of the other groups(P <0.01). There were similar while minor changes in ADR + OMT group. There was no significant adverse effects in OMT group. Conclusion OMT protects heart from adriamycin-induced injury in rabbits, which may relate to the decrease in level of antioxidant and apoptosis of myocardial cells.
