Objective To explore the gender difference in clinical features and outcomes of elderly patients with coronary true bifurcation lesions after percutaneous coronary intervention (PCI).Methods A total of 169 consecutive patients were included in the study, who were diagnosed coronary true bifurcation lesions by coronary angiography (CAG)and received PCI in our hospital from December 2013 to December 2015.All patients were divided into 2 groups according to their gender (71 femals and 98 males).Angiographic characteristics of the coronary lesions and clinical data were analyzed in both groups.Clinical outcomes during follow up were recorded and studied.Results The levels of total cholesterol (TC), triglyceride (TG),high density lipoprotein cholesterol (HDL-C) and low density lipoprotein cholesterol (LDL-C) in the female group were significantly higher than in the male group (all P<0.05).The levels of BUN,Cr,UA,CyC and TBIL in the female group were significantly lower than in the male group (all P<0.05).Comorbidity rates of hypertension and diabetes were higher in female patients without significant differences (P>0.05).The median follow-up time was 17 months and the incidence rate of overall adverse events in women was higher than that of men (25.4% vs.11.2%, P<0.05).Conclusions The clinical outcomes of elderly patients with coronary true bifurcation lesions after PCI had gender differences.The rates of adverse events in female patients was found significantly higher than male patients.

Objective To isolate and identify the adult neural stem cells from the parenchyma of spinal cord in adult mouse.Methods The parenchymal spinal cord from adult mouse was dissected and dissociated by mechanical trituration.The tissue suspension was cultured in serum-free DMEM/F12 medium supplemented with EGF and B27.The cell colonies generated from a single cell were screened by limited dilution and incubated with BrdU.The cell colonies were transferred into medium with serum to induce differentiation.The cells were identified with antibodies to Nestin,BrdU,MAP2 and GFAP by immunofluorescence staining.Results The cells were cultured for seven days to generate proliferative neurospheres.The majority of cells in these neurospheres expressed Nestin and were differentiated into MAP2-positive cells and GFAP-positive cells in medium containing with fetal bovine serum.Conclusion A significant number of neural stem cells are present in the parenchymal adult mouse spinal cord and can proliferate and also give rise to neurons and glia in vitro.

OBJECTIVETo investigate the protective effect of ginsenoside Rg1 on oxygen-glucose deprivation (OGD) in PC-12 cells, and preliminarily discuss the potential molecular mechanism of mTOR/Akt/FoxO3 signaling pathway.

METHODThe OGD PC-12 cell model was established. The cell viability was measured by MTT assay. After the pretreatment with Rg1 with the concentration of 10, 20, 40 micromol x L(-1) for 24 h, the cell viability was observed. Lactate dehydrogenase (LDH) release, superoxide dismutase (SOD) ac- tivity and malondialdehyde (MDA) level were detected by colorimetry assay. mTOR, p-Akt(ser473), p-Akt(tjr308), Akt, p-FoxO3, FoxO3 in cytoplasm and nucleus, and total FoxO3 protein expression were detected by Western blot assay.

RESULTOGD could significantly in- hibit cell proliferation in 4-24 h in a time-dependent manner. After pretreatment for 24 h, Rg1 (20, 40 micromol x L(-1)) could notably elevate the cell viability and SOD viability and reduce the LDH release and MDA content. Besides, Rg1 also inhibited OGD-induced mTOR and p-Akt(ser473) decreases. After treatment for 6 h, OGD could reduce FoxO3 phosphorylation and promote FoxO3 in cytoplasm. This data suggested that Rg1 could protect PC-12 cell injury through mTOR/p-Akt/FoxO3 signaling pathway.

CONCLUSIONGinsenoside Rg1 could attenuate OGD-induced PC-12 cell injury. Its action mechanism may be closely related to activation of mTOR/p-Akt/FoxO3 signaling pathway.

To study the suppression effect of light rare earth elements (RE) on proliferation of two cancer cell lines. Two cancer cell lines PAMC82 and K562 were used to examine their colony-forming ability in soft agar, microtubule structure, calmodulin levels and regulation of some gene expressions by Northern blot analysis with and without treatment by RE. The results showed that on soft agar culture the colony-forming ability of human gastric cancer cell line PAMC82 treated by RE chloride decreased and the PAMC82 cell microtubule abnormal structure became normal. The calmodulin (CaM) levels decreased in human leukemia cells (K562) treated with cerium chloride and neodymium chloride. The Northern blot analysis revealed marked up-regulation of p53, p16(MTS1), p21(WAF1) gene expressions in PAMC82 cells treated with lanthanum chloride and cerium chloride, as compared to control PAMC82 cells. The light rare earth elements studied have certain suppression effects on proliferation of cancer cells. This effect might be related to the decrease of calmodulin and up-regulation of some gene expressions in cancer cells.

[Objective]To evaluate the expression of enhancer of zeste homolog 2(EZH2),Ki-67 and intratumoral microvaseu?lar density(iMVD)in human colorectal cancer(CRC),and discuss their relationship with the biological behavior and prognosis.[Methods]The expression of EZH2,Ki-67 and iMVD(labeled by CD34 protein)was measured with immunohistochemical MaxVision method in CRC patients followed up over 5 years.[Results]Positive expression rates of EZH2,Ki-67 and iMVD were 40.91%(45/110),57.27%(63/110)and 46.36%(51/110),respectively. EZH2 expression was positively correlated with distant metastasis(P=0.024). Ki-67 expression was positively correlated with tumor size,infiltration depth,AJCC stage and differentiation(P=0.033~0.015). The iMVD expression was positively correlated with infiltration depth ,AJCC stage and differentiation (P=0.016~0.034). Spearman correlation analysis showed that EZH2 expression was positively correlated with Ki-67 expression(r=0.195,P=0.041), whereas negatively correlated with iMVD expression. Ki-67 expression had a positive correlation with iMVD(r=0.213,P=0.025). Multivariate analysis suggested that the EZH2 expression was an adverse independent factor for survivals of CRC patients(HR 1.965, 95%CI:1.019-3.789,P=0.044 for OS).[Conclusion]EZH2 expression was significantly correlate with the proliferation of tumor cells and may plays an important role in the metastasis and prognosis of CRC.

BACKGROUNDOnabotulinumtoxinA is widely used in treating neurogenic detrusor overactivity (NDO). We carried out a systematic review and meta-analysis to assess the efficacy and safety of the drug for treating NDO.

METHODSWe searched the following databases: Medline, EMBASE, and the Cochrane Controlled Trials Register. All published randomized double-blind, placebo-controlled trials of onabotulinumtoxinA for the treatment of NDO were identified in the analysis. The reference lists of the retrieved studies were also investigated.

RESULTSFour publications involving a total of 807 patients were identified in the analysis, which compared onabotulinumtoxinA with placebo. The changes of the mean number of urinary incontinence per week (the standardized mean difference [SMD] = -10.91, 95% confidence intervals [CIs] = -14.18--7.63, P < 0.0001); maximum cystometric capacity (SMD = 146.09, 95% CI = 126.19-165.99, P < 0.0001) and maximum detrusor pressure (SMD = -32.65, 95% CI = -37.83--27.48, P < 0.0001) indicated that onabotulinumtoxinA was more effective than the placebo, despite the doses of onabotulinumtoxinA. Safety assessments primarily localized to the urinary tract indicated onabotulinumtoxinA were often associated with more complications. Urinary tract infections (relative risk [RR] =1.48, 95% CI = 1.20-1.81, P = 0.0002); hematuria (RR = 1.81, 95% CI = 1.00-3.24, P = 0.05) and urinary retention (RR = 5.87, 95% CI = 3.61-9.56, P < 0.0001).

CONCLUSIONSThis meta-analysis indicates that onabotulinumtoxinA to be an effective treatment for NDO with side effects primarily localized to urinary tract.
