To investigate the effect of compound Chinese traditional medicine PC-SPES II I in inhibiting proliferation of human prostate cancer cell LNCaP based on the androgen receptor (AR) signaling pathway. The effect of PC-SPES II on LNCaP cell proliferation was detected by MTT assay. According to the findings, at the mass concentration of 180-1 440 mg x L(-1), PC-SPES II significantly inhibited the proliferation of LNCaP cells; the IC50 of PC-SPES II at 24 h and 48 h were 311.48, 199.01 mg x L(-1), respectively. The flow Cytometry detection showed 240 mg x L(-1) PC-SPES II arrested cells in G2/M phase, and an obvious apoptotic peak appeared before G0/G1 peak and rose over time. Meanwhile, Hoechst 33258 staining revealed apoptotic cellular morphology. Annexin V-FITC/PI staining manifested an increase in apoptotic cell ratio at the PC-SPES II concentration of 480 mg x L(-1) in a dose dependent manner. The prostate specific antigen (PSA) secretion of LNCaP cells was tested by PSA ELISA kit. Besides, compared with 25 mg x L(-1) Bic, 480 mg x L(-1) PC-SPES II significantly reduced the cell secretion of PSA. The AR and PSA mRNA and protein expressions were detected by qRT-PCR and Western blot. According to the results, after the induction of LNCaP cells with synthetic androgen 25 μg x L(-1) R1881, 240-480 mg x L(-1) PC-SPES II notably down-regulated the AR and PSA mRNA and protein expressions and inhibited the translocation of AR from cytoplasm to nucleus. In summary, PC-SPES II significantly can inhibit the in vitro proliferation of LNCaP cells and arrest cell cycle arrest in G2/M phase. Its mechanism may be associated with the down-regulation of the AR and PSA expressions and the inhibition of AR nuclear translocation.

Objective Measurement of ankle brachial index (ABI) is a simple method of assessing lower limb arterial blood supply,while measurement of toe brachial index (TBI)has only been advocated as an alternative.The aim of this study was to obtain information about whether TBI should be taken in type 2 diabetes,even when ABI is normal,and to evaluate the relationship between TBI and atherosclerosis.Methods In a crosssection study,ABI,TBI,and carotid intimal-medial thickness (IMT) were measured on 979 outpatients with type 2 diabetes in Ruijin Hospital.Those with normal ABI (0.9 ≤ABI < 1.3,n = 945) were divided into two groupsnormal TBI group(TBI≥0.6,n=893) and low TBI group(TBI<0.6,n=52),and then the clinical and laboratory data were compared between these two groups.Furthermore,the relationship between TBI and atherosclerosis was investigated.Atherosclerosis was defined as the maximum IMT ≥ 1.1 mm.Results Low ABI and low TBI were detected in 1.3% and 6.6% of the patients,respectively.Comparison of the clinical and laboratory data between the two groups showed that age and HbA1C values were significantly higher in the low TBI group.Furthermore,TBI was inversely associated with IMT(β=-0.217,P<0.01),an indicator for atherosclerosis of the carotid artery.Multiple logistic regression analysis revealed that decline of TBI was an independent risk factor of atherosclerosis (OR=1.30,95% CI 1.01-1.69,P<0.05).Conclusion In type 2 diabetes,the decline of TBI is associated with atherosclerosis,indicating the necessity for diabetic patients to detect TBI,even when ABI is within normal range,in order to detect peripheral artery disease in early stage,and reduce the risk for atherosclerosis.

Objective To investigate the clinical and pathological characteristics of normotensive pheochromocytomas ( NP) . Methods This retrospective study included 97 patients with a pathological diagnosis of pheochromocytoma at the Drum Tower Hospital Affiliated to Nanjing University Medical School during January 2004 to December 2013. All available clinical, biochemical, and radiological records were reviewed in these patients who were then categorized into hypertensive pheochromocytomas (HP) (n=64) and NP (n=33) groups. 97 cases of Adrenal Gland Scale Score of pheochromocytoma were examined, including tissue microscopic pathology assessment, ki67 and phenylethanolamine-N-methyltransferase ( PNMT ) immunohistochemistry and catecholamine type. Biochemical examinations of 95 subjects with primary hypertension ( PH) were recorded for comparative study. Results The patients with NP showed lower proportion of clinical triad than HP, inapparent metabolic disorders, and lower urinary catecholamine levels than HP, but showed higher results than primary hypertension. The weight of tumor was positively correlated with 24 hour urinary norepinephrine level in patients with HP(Y=1. 376+0. 653X,R2=0. 118, P=0. 028), but not in patients with NP;and the size or diameter of the tumor was negatively correlated with PNMT immunohistochemistry in patients with NP(Y=0. 940-0. 356X, R2=0. 494, P=0. 005), but not in patients with HP, indicating that NP may be misdiagnosed clinically. Conclusion Patients with NP have distinct clinical, biochemical, and pathological phenotypes; the phenotypic changes are closely related with the expression levels of catecholamine pathway products during the occurrence and development of the tumors.
