Objective To investigate the expression of signal-induced proliferation-associated gene 1 (SIPA1), Ezrin and E-cadherin (E-cad), and their relationship with clinical patterns in epithelial ovarian carcinoma.Methods Immunohistochemistry was used to detect the expression of SIPA1, Ezrin and E-cad in normal ovarian tissue, benign epithelial ovarian tumor, borderline epithelial ovarian tumor and epithelial ovarian carcinoma,respectively. Results The positive rate of SIPA1 expression was 44.2 % (23/52), 64.5 %(20/31), 93.3 % (28/30) and 100.0 % (15/15) in epithelial ovarian carcinoma, borderline epithelial ovarian tumor, benign epithelial ovarian tumor, and normal ovarian tissue, respectively, and there was a statistical difference (χ2 = 29.159, P= 0.000). The corresponding rates were 57.7 % (30/52), 61.3 % (19/31), 90.0 %(27/30) and 93.3 % (14/15) for the positive rate of Ezrin expression (χ2= 14.555, P= 0.002), as well as for 23.1 % (12/52), 58.1 % (18/31), 86.7 % (26/30) and 0 (0/15) for the positive rate of E-cad expression, respectively (χ2= 45.731, P= 0.000). In patients with epithelial ovarian carcinoma, the expression of SIPA1 was correlated with tumor differentiation (χ2=3.895, P=0.048), but not with histological type and clinical stage (all P>0.05). The expression of Ezrin was not correlated with histological type, tumor differentiation and clinical stage (all P>0.05). There was a positive correlation between expression of E-cad and SIPA1, Ezrin in epithelial ovarian carcinoma, respectively (r= 0.339, P= 0.014; r= 0.284, P= 0.041), but no correlation between the expression of SIPA1 and Ezrin (r= 0.214, P= 0.128). Conclusions SIPA1, Ezrin and E-cad play important roles in the occurrence and development of epithelial ovarian carcinoma. They cooperate in the progression and their combined detection can better evaluate the prognosis of epithelial ovarian carcinoma.

AIM: To investigate lipoprotein lipase gene HindⅢ polymorphism and its relationship with serum lipids and apolipoprotein, serum HDL subclasses in patients with hyperlipoidemia. METHODS: Lipoprotein lipase gene HindⅢ polymorphism was assayed by polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP). The subclasses of serum HDL in 152 hyperlipoidemia patients and 128 healthy subjects were determined by two-dimensional gel electrophoresis conjunction with immunodetection method. RESULTS: H+H+ genotype and allele H+ in hyperlipoidemia and control groups were both the highest. In hyperlipidemia group, H+H+ genotypes tended to be higher than that in control group, while H+H- and H-H- genotypes were significantly lower (P

OBJECTIVETo establish an HPLC fingerprint to evaluate the quality of Polygalae Radix, root xylem, and those collected in different growth ages or harvest time.

METHODSeparation was performed at 30 °C on a Kromasil C18 column (4.6 mm x 250 mm, 5 μm); the mobile phases was acetonitrile and 0.05% H3PO4 water in the gradient elution; the flow rate was set at 1.0 mL · min(-1) and the detection wavelength at 314 nm; the quality discriminant analyses were accomplished by means of similarity analysis, cluster analysis, principal component analysis and neural network model.

RESULTIn 26 batches of Polygalae Radix, 24 batches fingerprint similarities were above 0.8. In 5 different growth or harvest time batches, 4 batches were above 0.8; in 8 batches root xylem samples, the similarities were all above 0.875. The similarity analysis was in accord with the quality discriminant analysis of cluster analysis, principal component analysis and neural network model.

CONCLUSIONFingerprint combined with chemical pattern recognition technique can effectively evaluate the quality of Polygalae Radix. The active substance species are all similar in cultivated, wild, different growth or harvest time Polygalae Radix and polygala root xylem, but the chromatography peak areas are different. The effective material contents are similar between wild and cultivated Polygalae Radix, but each chromatographic peak area of the root xylem is much smaller than that of Polygalae Radix. The chemical substance accumulation mainly depends on harvest month, but little growth time in Polygalae Radix.

Aim To investigate the effect of artesunate on the invasion of human colon cancer Lovo cells and the possible mechanisms. Methods After Lovo cells were treated with different doses of artesunate(20,80, 160 μmol·L - 1 ), the soft agar colony formation test was adopted to observe the anchorage-independent pro-liferation of Lovo cells. Transwell assay was used to determine the effect of artesunate on the invasion abili-ty of Lovo cells. And the protein expressions of HMGB1 and MMP-2 were investigated by western blot. Results Artesunate could significantly inhibit both proliferation and invasion ability of Lovo cells in a dose-dependent manner(P < 0. 01). The experimental group treated with artesunate significantly down-regula-ted the protein expressions of HMGB1 and MMP-2 compared with control group(P < 0. 05). Conclusion Artesunate could inhibit the invasion of human colon cancer Lovo cells by down-regulating HMGB1 and MMP-2 expressions.

Aim To investigate the promoting apoptosis effect of artesunate( ART) on human colon cancer Lovo cells and its mechanisms. Methods MTT assay was performed to determine the anti-proliferative effect of artesunate. Flow cytometry assay and electron micros-copy( EM) were used to evaluate the apoptotic effect of artesunate. Luciferase reporter assay was introduced to measure the activation of Wnt/β-catenin pathway. Western blot was used to detect the pathway-related protein levels of β-catenin, GSK-3β,c-Myc and apop-tosis-related protein level of casepase-3 . Results Compared with the control group, the inhibitory rate of cell proliferation at 72 h and 320 μmol·L-1 ART was (78. 99 ± 1. 95 )% ( F =898. 301, P =0. 000 ); the cell apoptotic rate at 24 h and 160 μmol · L-1 ART was(19. 00 ± 0. 05)% and morphological signs of cell apoptosis were found by EM;the transcriptional activi-ty of TCF4/LEF at 24 h and 160 μmol·L-1 ART was (0. 36 ± 0. 30)%(F =470. 954,P <0. 01); the ex-pressions of caspase-3 and GSK-3β were significantly increased, whileβ-catenin and c-Myc were significant-ly decreased when treated with different concentrations of ART for 48 h ( P <0. 01 ) . Conclusion ART may significantly inhibit proliferation and promote apoptosis of Lovo cells probably by inactivating Wnt/β-catenin pathway.
