Zhang, En-Jiao,Cui, Zhi-Gang,Xu, Zhong-Fei,Duan, Wei-Yi,Huang, Shao-Hui,Tan, Xue-Xin,Yin, Zhi-Hua,Sun, Chang-Fu,Lu, Li Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.23

Background: To systematically summarize the association between the X-ray repair cross complementing 3 (XRCC3) gene polymorphism and oral cancer susceptibility by meta-analysis. Materials and Methods: Databases including PubMed, EMbase, CNKI, VIP and WanFang Data were searched to identify case-control studies concerning the association between an XRCC3 gene polymorphism and the risk of oral cancer from the inception to June 2014. Two reviewers independently screened the literature according to the criteria, extracted the data and assessed the quality. Then meta-analysis was performed using Stata 11.0 software. Results: Seven published case-control studies including 775 patients with oral cancer and 1922 controls were selected. Associations between the rs861539 polymorphism and overall oral cancer risk were not statistically significant in all kinds of comparison models (CT vs CC: OR=0.94, 95%CI=0.74-1.18; TT vs CC: OR=0.94, 95%CI=0.64-1.38; dominant model: OR=0.95, 95%CI=0.76-1.18; recessive model: OR=0.94, 95%CI=0.69-1.29; allele T vs C: OR=0.97, 95%CI=0.84-1.11). In the stratified analysis by ethnicity, no significant associations were found among Asians and Caucasians. On stratification by tumor type, no significant associations were found for cancer and oral premalignant lesions. Conclusions: The XRCC3 gene polymorphism was not found to be associated with the risk of oral cancer. Considering the limited quality of the included case-control studies, more high quality studies with large sample size are needed to verify the above conclusion.

You-en Zhang,Jia-ning Wang,Jun-ming Tang,Ling-yun Guo,Jian-ye Yang,Yong-zhang Huang,Yan Tan,Shou-zhi Fu,Xia Kong,Fei Zheng 한국분자세포생물학회 2009 Molecules and cells Vol.27 No.2

Myocardial ischemia-reperfusion injury is a medical problem occurring as damage to the myocardium following blood flow restoration after a critical period of coronary occlusion. Oxygen free radicals (OFR) are implicated in reperfusion injury after myocardial ischemia. The antioxidant enzyme, Cu, Zn-superoxide dismutase (Cu, Zn-SOD, also called SOD1) is one of the major means by which cells counteract the deleterious effects of OFR after ischemia. Recently, we reported that a PEP-1-SOD1 fusion protein was efficiently delivered into cultured cells and isolated rat hearts with ischemia-reperfusion injury. In the present study, we investigated the protective effects of the PEP-1-SOD1 fusion protein after ischemic insult. Immunofluorescecnce analysis revealed that the expressed and purified PEP-1-SOD1 fusion protein injected into rat tail veins was efficiently transduced into the myocardium with its native protein structure intact. When injected into Sprague-Dawley rat tail veins, the PEP-1-SOD1 fusion protein significantly attenuated myocardial ischemia-reperfusion damage; characterized by improving cardiac function of the left ventricle, decreasing infarct size, reducing the level of malondialdehyde (MDA), decreasing the release of creatine kinase (CK) and lactate dehydrogenase (LDH), and relieving cardiomyocyte apoptosis. These results suggest that the biologically active intact forms of PEP-1-SOD1 fusion protein will provide an efficient strategy for therapeutic delivery in various diseases related to SOD1 or to OFR.

Purpose: Lung cancer, one of the most frequently diagnosed cancers in the world, is characterized by relatively high morbidity and mortality. Berbamine (BER) has been initially reported to exert anti-proliferative effects against a series of cancers. Methods: In this study the in vitro cytotoxicity of BER was measured by MTT assay. In vivo anti-cancer efficacy of BER was assessed in A549 xenografts. Results: Cytotoxicity tests showed dose-dependent cell growth inhibition effects of BER against A549 cells. Moreover, BER significantly reduced the growth of lung cancer in a dose-dependent manner in nude mice with prolonged survival time. Conclusion: Therefore, BER might be in herbal medicine for cancer therapy and further efforts are needed to explore therapeutic strategies.

도핑효과에 따른 리튬이차전지용 NCA 양극활물질의 전기화학적 특성 향상

범지우 ( Zhi Yu Fan ),김은미 ( En Mei Jin ),정상문 ( Sang Mun Jeong ) 한국화학공학회 2017 Korean Chemical Engineering Research(HWAHAK KONGHA Vol.55 No.6

니켈 함량이 높은 리튬이차전지용 NCA 양극소재의 용량 및 수명특성을 향상시키기 위하여 붕소와 코발트를 상업용Li_1.06Ni_0.91Co_0.08Al_0.01O₂ (NCA)에 도핑하여 리튬이차전지의 양극소재로 사용하였다. 상업용 NCA 양극소재는 약 5 μm와 12 μm 크기의 2차 입자들이 혼합되어 있고 붕소와 코발트 도핑후 입자크기는 조금 감소되었다. 붕소와 코발트를 도핑한 NCA-B와 NCA-Co의 초기 방전용량은 각각 214 mAh/g과 200 mAh/g으로 도핑하지 않은 NCA에 비해 높게 나타났으며, 특히 NCA-Co는 20번째의 방전용량이 157mAh/g으로 가장 우수한 방전용량특성을 나타내었다. 이는 코발트를 도핑함으로써 c축 방향으로의 결정이 성장되어 리튬이온의 확산이 용이하기 때문이다. In order to improve the capacity and cycling stability of Ni-rich NCA cathode materials for lithium ion bat-teries, the boron and cobalt were doped in commercial Li_1.06Ni_0.91Co_0.08Al_0.01O₂ (NCA) powders. Commercial NCA par-ticles are mixed composites such as secondary particles of about 5 μm and 12 μm, and the particle size was decreased by doping boron and cobalt. The initial discharge capacities of the boron and cobalt doped NCA-B and NCA-Co were found to be 214 mAh/g and 200 mAh/g, respectively, which are higher values than that of the raw NCA cathode material. In par-ticular, NCA-Co exhibits the best discharge capacity of 157 mAh/g after 20 cycles, which is probably due to the enhanced diffusion of lithium ion by crystal growth along with the c-axis direction.

Yuejie Xie,Zhi-Fei He,Jingzhi Lv,En Zhang,Hong-Jun Li 한국축산식품학회 2016 한국축산식품학회지 Vol.36 No.6

The aim of this study was to explore the volatile compounds of hind leg, foreleg, abdomen and Longissimus dorsi in both male and female Hyla rabbit meat by solid phase microextraction tandem with gas chromatography mass spectrometry, and to seek out the key odorants via calculating the odor activity value and principal component analysis. Cluster analysis is used to study the flavor pattern differences in four edible parts. Sixty three volatile compounds were detected, including 23 aldehydes, 4 alcohols, 5 ketones, 11 esters, 5 aromatics, 8 acids and 7 hydrocarbons. Among them, 6 aldehydes and 3 acids were identified as the potential key odorants according to the ratio of concentration and threshold. The contents of volatile compounds in male Hyla rabbit meat were significantly higher than those in female one (p<0.05). The results of principal component analysis showed that the first two principal component cumulative variance contributions reach 87.69%; Hexanal, octanal, 2-nonenal, 2-decenal and decanal were regard as the key odorants of Hyla rabbit meat by combining odor activity value and principal component analysis. Therefore volatile compounds of rabbit meat can be effectively characterized. Cluster analysis indicated that volatile chemical compounds of Longissimus dorsi were significantly different from other three parts, which provide reliable information for rabbit processing industry and for possible future sale.

Leucogen Tablets at 60 mg Three Times per Day are Safe and Effective to Control Febrile Neutropenia

Huang, Xin-En,Cao, Jie,Qian, Zhi-Ying,Xu, Xia,Shi, Lin,Wu, Xue-Yan,Liu, Jin,Wang, Lin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19

Purpose: To investigate whether it is safe to use leucogen tablets 60 mg three times per day (180 mg for a day) and whether this regimen could reduce the incidence of febrile neutropenia caused by chemotherapy. Methods: This prospectively designed study focused on the safety and effectiveness of leucogen tablets 60mg three times per day for a group of cancer patients during chemotherapy for mainly lung or gastric cancers. The tablets were administered from 5 days before until the termination of chemotherapy. Neutropenia and other healthcare encounters were defined as events and occurrence was estimated for comparison. Results: We identified 39 patients receiving leucogen tablets 60mg three times per day, including 11 with gastric, 12 with lung and 16 with other sites of cancer. The mean age was 65 (29-75) years and there were 27 male and 12 female patients. The mean duration of leucogen tablets intake was 59 days. Eighteen patients were treated with taxane-based, 4 with irinotecan-based and 17 with other chemotherapy. The incidence of febrile neutropenia was 0%. Twelve patients were found severe neutropenia (grade III/IV), and the duration of severe neutropenia (grade III/IV) was 5 days. Treatment-emergent adverse events were attributable to complications of myelosuppressive chemotherapy or the primary disease (i.e., alopecia, nausea, asthenia, neutropenia, and severe hepatic renal dysfunction). No chemotherapy was delayed and no treatment related death was observed. Conclusions: This study suggested that leucogen tablets 60mg three times per day (180mg for a day) are safe and could be effective for preventing febrile neutropenia in patients with chemotherapy.

Hsa-miR-181a-5p Expression and Effects on Cell Proliferation in Gastric Cancer

Chen, Gang,Shen, Zhi-Li,Wang, Ling,Lv, Chun-Ye,Huang, Xin-En,Zhou, Rong-Ping Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

Purpose: MicroRNAs (miRNAs) are small endogenous, non-coding, single-stranded RNAs (approximately 22 nt). Accumulating evidence has shown that aberrant miRNA expression is pronounced and correlated with gastric cancer genesis and progression. Materials and Methods: Expression levels of miR-181a-5p in GC tissues and cell lines were assessed by qRT-PCR and tested for correlation with clinical features. In addition, effects of miR-181a-5p on GC cell growth were investigated. Results: Our findings indicate that miR-181a-5p is upregulated in GC, in correlation with lymph node invasion, nerve invasion and vascular invasion (P<0.05). Enforced expression of miR-181a -5p promoted cell proliferation ability. Conclusions: This study suggested that increased miR-181a-5p is related to GC progression. MiR-181a-5p may represent a potential therapeutic target for GC.
