Ling-Ling Xie,Li-Qin You,Xiao-Yu Cao,Chao-Feng Zhang,Da-Wei Song,Ling-Bo Qu 대한금속·재료학회 2012 ELECTRONIC MATERIALS LETTERS Vol.8 No.4

Co3(PO4)2-coated LiV3O8 has been successfully synthesized and used as positive material for rechargeable lithium batteries by a facile liquid phase method. The as-prepared powders were characterized by x-ray diffraction (XRD), scanning electron microscope (SEM), transmission electron microscope (TEM), and the galvanostatic discharge/charge experiments. As-prepared Co3(PO4)2-coated LiV3O8 forms a good layered structure with a poor cyrstallinity. SEM reveals that Co3(PO4)2-coated LiV3O8 has uniform particle distribution and reduced particle size when compared with bare one. The Co3(PO4)2 coating layer is about 33 - 59 nm forming a continuous lumps attached to LiV3O8 particle surface. Co3(PO4)2-coated LiV3O8 electrode shows increased capacity and more stable cycling. The first and 35th discharge capacities of the Co3(PO4)2-coated LiV3O8electrode are 322.8 mAh g−1 and 235.7 mAh g−1 in the range of 4.0 - 1.8 V at a current rate of 30 mA g−1, respectively. The improved electrochemical performance is assigned to the greatly reduced LiV3O8 particle with uniform morphology. Co3(PO4)2-coating further benefits the phase transitions of LiV3O8 during discharge/charge while preventing parasite reactions between electrode surface and electrolyte.

Ling-Ling Xie,Xiao-Yu Cao,Li-Xu Zhang,Zhong-Xu Dai,Ling-Bo Qu 대한금속·재료학회 2013 ELECTRONIC MATERIALS LETTERS Vol.9 No.2

A LiV3O8/polyaniline (PAn) composite was prepared by the in-situ polymerization method assisted by sodium dodecyl sulfate and ammonium persulfate. The as-prepared powders were investigated by XRD, SEM, and galvanostatic discharge/charge analysis. It was found that the introduction of PAn to LiV3O8 can effectively buffer the mechanical stress and restrain the number of phase changes of composite material during the electrochemical cycling. Compared with pristine LiV3O8, LiV3O8/PAn composite maintains a reversible capacity of 212.1 mAh g−1 at the current density of 30 mA g−1 after 50 cycles, approximately 22.6%, much higher than the former.

Rheological Phase Synthesis of Er-Doped LiV3O8 as Electroactive Material for a Cathode of Secondary Lithium Storage

Ling-Ling Xie,Yuan-Dong Xu,Jie-Jie Zhang,Cheng-Peng Zhang,Xiao-Yu Cao,Ling-Bo Qu 대한금속·재료학회 2013 ELECTRONIC MATERIALS LETTERS Vol.9 No.4

Er-doped LiV3O8 as cathode material for secondary lithium batteries was prepared through a rheological phase reaction method. The as-prepared materials were investigated by x-ray diffraction (XRD), scanning electron microscopy (SEM), and galvanostatic discharge/charge measurements. The results indicate that Er doped phase preserves the layered structure of the pristine LiV3O8 and has an enlarged interlayer spacing. Compared to LiV3O8 sample, Er-doped LiV3O8 sample displays more uniform particles and large surface area. The electrochemical test shows that Er doping does not change the process of Li+ insertion/deinsertion. Er-doped LiV3O8 electrode exhibits an initial discharge capacity of 294.2 mAh g−1 and maintains a stable capacity of 220.7 mAh g−1 after 50 cycles, indicating a greatly improved good cycleability comparing with the undoped one.

Abrin Induces HeLa Cell Apoptosis by Cytochrome с Release and Caspase Activation

( Xiao Ling Qu ),( Liu Ting Qing ) 생화학분자생물학회 2004 BMB Reports Vol.37 No.4

We identified apoptosis as being a significant mechanism of toxicity following the exposure of HeLa cell cultures to abrin holotoxin, which is in addition to its inhibition of protein biosynthesis by N-glycosidase activity. The treatment of HeLa cell cultures with abrin resulted in apoptotic cell death, as characterized by morphological and biochemical changes, i.e., cell shrinkage, internudeosomal DNA fragmentation, the occurrence of hypodiploid DNA, chromatin condensation, nudear breakdown, DNA single strand breaks by TUNEL assay, and phosphatidylserine (PS) externalization. This apoptotic cell death was accompanied by caspase-9 and caspase-3 activation, as indicated by the cleavage of caspase substrates, which was preceded by mitochondrial cytochrome c release. The broad-spectrum caspase inhibitor, benzyloxycarbonyl-Val-Ala-Asp-fluoromethyl ketone (zVAD-fmk), prevented abrin-triggered caspase activation and partially abolished apoptotic cell death, but did not affect mitochondrial cytochrome c release. These results suggest that the release of mitochondrial cytochrome c, and the sequential caspase-9 and caspase-3 activations are important events in the signal transduction pathway of abrin-induced apoptotic cell death in the HeLa cell line.

Pre-treatment Elevated Platelet Count Associates with HER2 Overexpression and Prognosis in Patients with Breast Cancer

Gu, Mei-Ling,Yuan, Cai-Jun,Liu, Xiao-Mei,Zhou, Yi-Chao,Di, Shu-Huan,Sun, Fei-Fei,Qu, Quan-Ying Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.13

Purpose: To research the association between pre-treatment elevated platelet count and clinicopathologic characteristics in breast cancer (BC), as well as explore the relationship between pre-treatment elevated platelet count and HER2 status and prognosis of BC patients. Materials and Methods: A retrospective cohort of BC patients who were newly diagnosed or treated by surgery only and had pathological detection results and platelet values in the Department of Oncology, the First Affiliated Hospital of Liaoning Medical College were enrolled from 1/1/2008 until 31/12/2009, and followed up until 31/12/2014. Age, thrombocyte parameters before chemotherapy and/or radiotherapy, immunohistochemical (IHM) indexes, and regional lymph node (LN) involvement and progression-free survival (PFS) were recorded. Results: A total of 447 eligible subjects were included in this research. As we analyzed, for HER2, positive and negative, the incidence rates of elevated platelet count were 25.8% and 14.7% (P<0.05). In the Cox proportional hazards model both variables were independent risk factors for BC (for HER2, OR, 0.592, 95% confidence interval, CI, 0.355 to 0.985, P=0.044;f or PLT, OR, 0.998, 95% CI, 0.996 to 1.000, P=0.042). For ER, PR, Ki67 and LN involvement, the differences were not statistically significant (P>0.05). Conclusions: In this research, pre-treatment elevated level of platelet count demostrated a significantrelationship with HER2 amplification/overexpression, and both variables significantly influenced the prognosis of BC. However, elevated platelet count did not exhibit any association with ER, PR, Ki67 and LN involvement.

Progress and Challenges in Chemotherapy for Loco-Regionally Advanced Nasopharyngeal Carcinoma

Liang, Zhong-Guo,Chen, Ze-Tan,Li, Ling,Qu, Song,Zhu, Xiao-Dong Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.12

Incidence rates of nasopharyngeal carcinoma are high in Indonesia, Singapore and South-Eastern China. Chemoradiotherapy has been the standard regimen for locally advanced nasopharyngeal carcinoma according to guidelines from the National Comprehensive Cancer Network. Recently, advances in the management of nasopharyngeal carcinoma have transferred into better treatment outcomes. Most phase III clinical trials support the addition of concurrent chemotherapy to radiotherapy for the initial treatment of these patients. Studies evaluating effects and toxicity of concurrent chemotherapy with different regimens have been reported. However, the status of adding adjuvant chemotherapy or induction chemotherapy remains controversial. Recent studies have shown that adjuvant chemotherapy with two or three cycles may improve survival for nasopharyngeal carcinoma with stage N2-3 disease or with persistently detectable plasma EBV DNA after radiotherapy. This review examines the pertinent issues and latest studies concerning the management of loco-regionally advanced NPC, regarding concurrent chemotherapy, adjuvant chemotherapy, and induction chemotherapy in decades.

This study investigates the hepatoprotectiveeffects and the potential therapeutic mechanisms of loach(Misgurnus anguillicaudatus) lyophilized powder (MLP)on dimethylnitrosamine (DMN) induced liver fibrosis inrats. After treatment with MLP (50, 100, 200 mg/kg),alanine aminotransferase (ALT), aspartate aminotransferase(AST), albumin (Alb), total protein (TP) andhydroxyproline (Hyp) levels were detected, to assess thedestruction of hepatocytes and the extent of liver fibrosis. Matrix metalloproteinase-2 (MMP-2), matrix metalloproteinase-9 (MMP-9), hyaluronic acid (HA), Laminin (LN),procollagen type-III (PC-III), collagen type-IV (C-IV), andtransforming growth factor-b1 (TGF-b1) contents in serumwere all tested using ELISA kits. Alpha-smooth muscleactin (a-SMA) and the tissue inhibitor of metalloproteinase-1 (TIMP-1) protein contents and distribution wereevaluated using western blot and immunohistochemicalanalysis. MLP significantly decreased the serum concentrationsof ALT, AST, Hyp, HA, LN, PC-III, C-IV, MMP-2,TIMP-1, a-SMA and TGF-b1, while increasing the contentsof Alb and MMP-9. No significant changes on TP serum concentrations were observed. These results suggest thatMLP has anti-hepatic fibrosis effects and its mechanism maybe associated with the attenuation of extracellular matrix(ECM) synthesis, the acceleration of ECM degradation,inhibition of hepatic stellate cells (HSCs) activation andTGF-b1 expression.
