Objective To investigate the the expression of soluble Fas (sFas) in the placenta of pregnancy induced hypertension (PIH) patients after perinatal. Methods Expression of sFas were detected by Fluorescent MGB Probe Real-Time PCR in 34 severe PIH patients and 30 healthy pregnant women served as normal controls.Results Expression of placenta sFas in 34 patients were significantly higher than those in normal controls.Conclusion PIH patients' placenta had higher expressiom of sFas; Detection of sFas may be helpful to value PIH degrade and sFas would be become a indicative markers of cell proliferation and apoptosis during the perinatal period.

AIM: To explore the effect and mechanism of preoperative transarterial chemoembolization on nephroblastoma.METHODS: Comparative analysis of clinical and pathological features in 39 children with Wilms’ tumor was conducted. TUNEL assay was used to detect the apoptosis of tumor in two groups with or without preoperative interventional treatment. The expressions of P53, Bcl-2 and Bax proteins were detected by immunochemical methods. The patients were followed-up for more than 2 years.RESULTS: The extent of neoplastic cell necrosis and degeneration, interstital fiber tissue hyperplasia of tumor and the number of infiltrating lymphocytes were observed, which were higher in interventional group than those in simple excision group (P

OBJECTIVETo investigate the effects of simvastatin on the proliferation and apoptosis of prostatic epithelial RWPE-1 cells.
METHODSRWPE-1 cells cultured in vitro were treated with simvastatin at 0, 10, 20, and 40 μmol/L for 24, 48, and 72 hours followed by determination of their proliferation by MTT assay, and their apoptosis by flow cytometry. The mRNA and protein expressions of Bcl-2, Bax, and Cx43 were detected by fluorescence quantitative RT-PCR and Western blot, respectively.
RESULTSAfter 72 hours of treatment with simvastatin at 10, 20, and 40 μmol/L, the inhibition rates of the RWPE-1 cells were (21.07 ± 6.41)%, (34.87 ± 9.65)%, and (47.18 ± 10.88)%, respectively, significantly higher than (1.21 ± 0.54)% in the control group (P < 0.05) and in a dose-dependent manner (P < 0.05); the cell apoptosis rates were (0.066 ± 0.016)%, (0.126 ± 0.023)%, and (0.192 ± 0.025)%, respectively, remarkably higher than (0.015 ± 0.005)% in the control (P < 0.05) and also in a dose-dependent manner (P < 0.05); the mRNA and protein expressions of Bcl-2 were decreasing while those of Bax and Cx43 increasing with the increased concentration of simvastatin (P < 0.05). The expression of Cx43 was correlated negatively with that of Bcl-2 but positively with that of Bax.
CONCLUSIONSimvastatin inhibits the proliferation of prostate epithelial cells and induce their apoptosis by acting on the gap junctional intercellular communication.

OBJECTIVETo explore the mechanism of shikonin for inducing the apoptosis of human promyelocytic leukemia cell HL-60.
METHODSThe effects of shikonin on the HL-60 cell proliferation were detected using MTT. The apoptosis rate was analyzed by Annexin-V/PI double staining. The expression level of the bcl-2 gene was detected using semi-quantitative reverse transcriptase PCR (RT-PCR), thus analyzing the correlation between the bcl-2 expression level and the apoptosis of HL-60.
RESULTSShikonin could inhibit the proliferation of HL-60 cells with the concentration range of 1-8 microg/mL in a time- and concentration-dependent manner. Two microg/mL shikonin could induce the apoptosis of HL-60 cells in a time-dependent manner. The expression level of bcl-2 was obviously down-regulated at 2 microg/mL shikonin.
CONCLUSIONSShikonin could induce the apoptosis of HL-60 cells. Its mechanism was correlated with down-regulation of the expression level of bcl-2.

OBJECTIVETo determine whether oral statins can delay the progression of benign prostatic hyperplasia (BPH) and lower urinary tract symptoms (LUTS).
METHODSWe conducted a retrospective cohort study of 50-69-year-old males who came for physical examination in our hospital between January 2003 and December 2008. We designed the inclusion criteria, followed them up for 5 years, and investigated the relationship of oral statins with the clinical progression of BPH and LUTS.
RESULTSTotally, 653 men met the inclusion criteria and were included in this study, of whom 283 were treated with oral statins (group 1) while the other 370 with none (group 2). There were no statistically significant differences between the two groups in age and baseline IPSS, Qmax, and prostate volume (PV) (P > 0.05). During the follow-up, 24 cases in group 1 and 35 cases in group 2 were excluded for obvious dys-uria. A gradual increase was observed in IPSS in both groups 1 and 2 year by year from the baseline to the 5th year of follow-up, but significantly lower in the former group (4.27 +/- 1.16, 4.63 +/- 1.05, 5.27 +/- 0.96, 6.41 +/- 1.04, 7.21 +/- 1.21, and 7.93 +/-1.50) than in the latter (4.24 +/- 1.35, 5.26 +/- 1.23, 6.84 +/- 1.20, 8.75 +/- 1.84, 10.82 +/- 3.01, and 12.98 +/- 4.21) (P < 0.01); a gradual decrease was seen in Qmax, though markedly higher in group 1 ([26.56 +/- 2.09], [24.06 +/- 1.94], [21.33 +/- 1.66], [19.24 +/- 1.54], [17.44 +/- 1.53], and [16.27 +/- 1.37] ml/s) than in group 2 ([26.74 +/- 2.40], [23.62 +/- 2.01], [20.63 +/- 1.69], [17.72 +/- 1.48], [14.82 +/- 1.11], and [11.86 +/- 1.24] ml/s) (P < 0.01); and a gradual increase was found in PV, but remarkably smaller in the former group ([19.82 +/- 4.94], [22.60 +/- 4.99], [25.80 +/- 5.20], [27.92 +/- 5.05], [29.11 +/- 5.24], and [29.97 +/- 5.26] ml) than in the latter ([20.21 +/- 4.78], [24.30 +/- 4.98], [28.50 +/- 5.14], [32.84 +/- 4.77], [36.99 +/- 4.78], and [40.90 +/- 4.78] ml) (P < 0.01). Longer medication of statins was associated with better efficacy.
CONCLUSIONOral statins can significantly delay the clinical progression of BPH and LUTS.

The aim of this study is to evaluate anti-tumor activities and mechanism of a novel kinase inhibitor ZLJ213 which targeted Aurora A and vascular endothelial growth factor receptor (VEGFR) in vitro and in vivo against human colon cancer. Results showed that ZLJ213 inhibited cell proliferation and induced cell cycle arrest and apoptosis of HCT1 16 and SW48 cell lines. In HCT116-derived xenograft, ZLJ213 dosed at 100 mg · kg(-1) inhibited tumor growth by 73.24%. The IC50 of ZLJ213 on the expression of p-Aurora A was 0.258 µmol · L(-1) analyzed by ELISA. Under the concentration of 0.08 µmol · L(-1), ZLJ213 could inhibit the activities of Aurora A, Histone H3 and VEGFR of HCT116 and SW48 cell lines. Simultaneously, ZLJ213 induced activation of Caspase 3 and PARP cleavage. Above data suggested that ZLJ213 had the ability to inhibit cell proliferation and induce cell apoptosis both in vitro and in vivo in colon cancer, and down-regulate the expression of p-Aurora A and p-VEGFR. ZLJ213 might be a potential therapeutic agent against colon cancer.
