The effects of aqueous extract of Schizandrae Fructus (AESC) on lead (Pb)-induced changes of monoamine neurotransmitters in the hippocampus (HIP) of adult rats were investigated. Male Sprague-Dawley rats were received intraperitoneal (i.p.) administration of Pb acetate (5 mg/kg/d) for 28 days and sacrificed 7 days after the last administration. Concentrations of norepinephrine (NE), dopamine (DA), serotonin (5-HT), 5-hydroxyindole acetic acid (5-HIAA) in HIP were measured by HPLC. There were significant decreases of NE, DA, 5-HT and 5-HIAA in Pb treated rats (P < 0.05), while pretreatment with AESC (100 mg/kg/d or 300 mg/kg/d, p.o., 2 h before Pb) greatly inhibited the decrease of monoamine transmitters, respectively (P < 0.05). Also, AESC (300 mg/kg/d) significantly increased the reduction of glutathione contents and superoxide dismutase activities in HIP induced by chronic Pb. These results suggest that AESC ameliorates Pb-induced depletion of monoamine neurotransmitters in HIP through its antioxidant activity.

The prognostic value of the fibroblast growth factor-inducible 14 (Fn14) expression in hepatocellular carcinoma (HCC) is unknown. Real-time PCR (RT-PCR), western blot assays and immunohistochemistry analysis were here performed in order to compare Fn14 expressios in paired liver samples of HCC and normal liver tissue. Most of the tumor tissues expressed significantly higher levels of Fn14 compared to adjacent non-tumor tissues, with Fn14High accounting for 54.6% (142/260) of all patients. The Pearson ${\chi}^2$ test indicated that Fn14 expression was closely associated with serum alpha fetal protein (AFP) (P=0.002) and tumor number (p=0.019). Univariate and multivariate analyses revealed that along with tumor diameter and portal vein tumor thrombosis (PVTT ) type, Fn14 was an independent prognostic factor for both overall survival (OS) (HR=1.398, p=0.008) and recurrence (HR=1.541, p=0.001) rates. Fn14 overexpression HCC correlated with poor surgical outcome, and this molecule may be a candidate biomarker for prognosis as well as a target for therapy.

Purpose: Synuclein-γ (SNCG), which was initially identified asbreast cancer specific gene 1, is highly expressed in advancedbreast cancers, but not in normal or benign breast tissue. Thisstudy aimed to evaluate the effects of SNCG siRNA-treatmenton breast cancer cells and elucidate the associated mechanisms. Methods: Vectors containing SNCG and negative control(NC) siRNAs were transfected into MDA-MB-231 cells; mRNAlevels were determined by real-time polymerase chain reaction. Cell proliferation was evaluated using the MTT assay, cell migrationwas assessed by the Transwell assay, apoptosis and cellcycle analyses were conducted with the flow cytometer, andWestern blot analysis was performed to determine the relativelevels of AKT, ERK, p-AKT, and p-ERK expression. Results:SNCG mRNA levels were significantly reduced in MDA-MB-231cells transfected with SNCG siRNA. Our results indicate that inSNCG siRNA-treated cells, cell migration and proliferation decreasedsignificantly, apoptosis was induced, and the cell cyclewas arrested. Western blot analysis indicated that the proteinlevels of p-AKT and p-ERK were much lower in the SNCG siRNA-treated groups, than in the control and NC groups. Conclusion:SNCG siRNA could decrease the migration and proliferationof breast cancer cells by downregulating the phosphorylationof AKT and ERK.

Novel small-molecule polysaccharide fractions,named POP II and POP III, were purified from Portulacaoleracea L. with average Mw values of 9.25 and 8.03 kDa,respectively. Monosaccharide analysis revealed that POP IIwas composed of Rha, Ara, Man, Glc, and Gal with molarratios of 1: 1.42: 0.44: 0.88: 1.59. POP III was composedof Rha, Ara, Glc, and Gal with molar ratios of 1: 1.16:0.23: 0.59. The antioxidant activities of the fractions wereevaluated using cell-free and cell-mediated radical generatingsystems. POPII and POP III possessed strong antioxidantactivities in both systems. The 2 novel polysaccharidefractions extracted from P. oleracea L. can be developed asnatural antioxidants for treatment of free radical-relateddiseases.
