      • SDSS J013127.34-032100.1: A NEWLY DISCOVERED RADIO-LOUD QUASAR AT <i>z</i> = 5.18 WITH EXTREMELY HIGH LUMINOSITY

        Yi, Wei-Min,Wang, Feige,Wu, Xue-Bing,Yang, Jinyi,Bai, Jin-Ming,Fan, Xiaohui,Brandt, William N.,Ho, Luis C.,Zuo, Wenwen,Kim, Minjin,Wang, Ran,Yang, Qian,Zhang, Ju-jia,Wang, Fang,Wang, Jian-Guo,Ai, Yanl IOP Publishing 2014 ASTROPHYSICAL JOURNAL LETTERS - Vol.795 No.2

        <P>Very few of the z > 5 quasars discovered to date have been radio-loud, with radio-to-optical flux ratios (radio-loudness parameters) higher than 10. Here we report the discovery of an optically luminous radio-loud quasar, SDSS J013127.34-032100.1 (J0131-0321 in short), at z = 5.18 +/- 0.01 using the Lijiang 2.4 m and Magellan telescopes. J0131-0321 has a spectral energy distribution consistent with that of radio-loud quasars. With an i-band magnitude of 18.47 and a radio flux density of 33 mJy, its radio-loudness parameter is similar to 100. The optical and near-infrared spectra taken by Magellan enable us to estimate its bolometric luminosity to be L-bol similar to 1.1 x 10(48) erg s(-1), approximately 4.5 times greater than that of the most distant quasar known to date. The black hole mass of J0131-0321 is estimated to be 2.7 x 10(9) M-circle dot, with an uncertainty up to 0.4 dex. Detailed physical properties of this high-redshift, radio-loud, potentially super-Eddington quasar can be probed in the future with more dedicated and intensive follow-up observations using multi-wavelength facilities.</P>

        Prognostic Threshold of Neuroendocrine Differentiation in Gastric Carcinoma: a Clinicopathological Study of 945 Cases

        Yi Zou,Linying Chen,Xingfu Wang,Yupeng Chen,Liwen Hu,Saifan Zeng,Pengcheng Wang,Guoping Li,Ming Huang,Liting Wang,Shi He,Sanyan Li,Lihui Jian,Sheng Zhang 대한위암학회 2019 Journal of gastric cancer Vol.19 No.1

        Purpose: The significance of neuroendocrine differentiation (NED) in gastric carcinoma (GC) is controversial, leading to ambiguous concepts in traditional classifications. This study aimed to determine the prognostic threshold of meaningful NED in GC and clarify its unclear features in existing classifications. Materials and Methods: Immunohistochemical staining for synaptophysin, chromogranin A, and neural cell adhesion molecule was performed for 945 GC specimens. Survival analysis was performed using the log-rank test and univariate/multivariate models with percentages of NED (PNED) and demographic and clinicopathological parameters. Results: In total, 275 (29.1%) cases were immunoreactive to at least 1 neuroendocrine (NE) marker. GC-NED was more common in the upper third of the stomach. PNED, and Borrmann's classification and tumor, lymph node, metastasis stages were independent prognostic factors. The cutoff PNED was 10%, beyond which patients had significantly worse outcomes, although the risk did not increase with higher PNED. Tumors with ≥10% NED tended to manifest as Borrmann type III lesion with mixed/diffuse morphology and poorer histological differentiation; the NE components in this population mainly grew in insulae/nests, which differed from the predominant growth pattern (glandular/acinar) in GC with <10% NED. Conclusions: GC with ≥10% NED should be classified as a distinct subtype because of its worse prognosis, and more attention should be paid to the necessity of additional therapeutics for NE components.

      • Associations Between Three Polymorphisms in the Interleukin-4 Receptor Gene and Risk of Cancer: a Meta-analysis

        Wang, Jia-Yi,Zhou, Yu-Qiao,Li, Xiao-Xu,Jin, Xin,Wang, Li-Li,Lei, Lei,Zhou, Yu,Lu, Jiang,Zeng, Xin,Dan, Hong-Xia,Liao, Ga,Chen, Qian-Ming Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12

        Interleukin-4 receptor (IL-4R) gene single nucleotide polymorphisms (SNPs) are implicated in cancer development. However, results from the published reports have remained inconclusive. The objective of this study was to conduct a meta-analysis investigating the association between polymorphisms in IL-4R gene and cancer risk. Pubmed, EMBASE and China National Knowledge Infrastructure (CNKI) were searched for case-control studies published up to October 30, 2012 that investigated IL-4R polymorphisms and cancer risk. Odds ratios (ORs) and 95% confidence intervals (CIs) were used to evaluate the strength of any associations. Three IL-4R polymorphisms (Q576R, rs1801275; I75V, rs1805010; S503P, rs1805015) in 21 case-control studies were analyzed. Our meta-analysis indicated that these three polymorphisms are not associated with cancer risk when all studies were pooled together. In the subgroup analysis by tumor site, the results showed that Q576R G allele carriers were associated with a significantly decreased cervical cancer risk (recessive model: OR = 0.77, 95%CI = 0.60-0.98; homozygote comparison: OR = 0.76, 95%CI = 0.58-0.98). I75V G allele carriers were associated with a decreased risk of renal cancer (dominant model = 0.71, 95%CI = 0.57-0.89, heterozygote comparison: OR = 0.69, 95%CI = 0.55-0.87). When stratified by ethnicity, Q576R G allele carriers were associated with a decreased cancer risk in Caucasians (dominant model: OR = 0.90, 95%CI = 0.83-0.98; heterozygote comparison: OR = 0.89, 95%CI = 0.82-0.98). I75V G allele carriers were associated with a decreased cancer risk in Asians (heterozygote comparison: OR = 0.76, 95%CI = 0.62-0.94). S503P C allele carriers were also associated with a decreased cancer risk in Asians (CC VS TT: OR = 0.29, 95%CI = 0.08-0.99). Our results suggest that Q576R, I75V and S503P may be associated with a decreased cancer risk for certain types of cancers and in some specific ethnic groups. Future case-control studies with large sample size are needed to evaluate these associations in detail.

        Notch1 promotes the pericytemyofibroblast transition in idiopathic pulmonary fibrosis through the PDGFR/ ROCK1 signal pathway

        Yi-Chun Wang,Qiong Chen,Jun-Ming Luo,Jing Nie,Qing-He Meng,Wei Shuai,Han Xie,Jia-Mei Xia,Hui Wang 생화학분자생물학회 2019 Experimental and molecular medicine Vol.51 No.-

        The goals of this study were to investigate the role of the Notch1/PDGFRβ/ROCK1 signaling pathway in the pathogenesis of pulmonary fibrosis and to explore the possibility of treating fibrosis by targeting Notch1. Lung tissues from patients with pulmonary fibrosis were examined for the expression of Notch1/PDGFRβ/ROCK1 using RT-qPCR, western blotting, and immunostaining. Cultured mouse lung pericytes were transfected with Notch1-overexpressed vectors or shRNA targeting PDGFRβ/ROCK1 to examine cell behaviors, including proliferation, cell cycle arrest, and differentiation toward myofibroblasts. Finally, a mouse pulmonary fibrosis model was prepared, and a Notch1 inhibitor was administered to observe tissue morphology and pericyte cell behaviors. Human pulmonary fibrotic tissues presented with overexpression of Notch1, PDGFRβ, and ROCK1, in addition to a prominent transition of pericytes into myofibroblasts. In cultured mouse lung pericytes, overexpression of Notch1 led to the accelerated proliferation and differentiation of cells, and it also increased the expression of the PDGFRβ and ROCK1 proteins. The knockdown of PDGFRβ/ROCK1 in pericytes remarkably suppressed pericyte proliferation and differentiation. As further substantiation, the administration of a Notch1 inhibitor in a mouse model of lung fibrosis inhibited the PDGFRβ/ROCK1 pathway, suppressed pericyte proliferation and differentiation, and alleviated the severity of fibrosis. Our results showed that the Notch1 signaling pathway was aberrantly activated in pulmonary fibrosis, and this pathway may facilitate disease progression via mediating pericyte proliferation and differentiation. The inhibition of the Notch1 pathway may provide one promising treatment strategy for pulmonary fibrosis.

      • Freeze-Casting Produces a Graphene Oxide Aerogel with a Radial and Centrosymmetric Structure

        Wang, Chunhui,Chen, Xiong,Wang, Bin,Huang, Ming,Wang, Bo,Jiang, Yi,Ruoff, Rodney S. American Chemical Society 2018 ACS NANO Vol.12 No.6

        <P>We report the assembly of graphene oxide (G-O) building blocks into a vertical and radially aligned structure by a bidirectional freeze-casting approach. The crystallization of water to ice assembles the G-O sheets into a structure, a G-O aerogel whose local structure mimics turbine blades. The centimeter-scale radiating structure in this aerogel has many channels whose width increases with distance from the center. This was achieved by controlling the formation of the ice crystals in the aqueous G-O dispersion that grew radially in the shape of lamellae during freezing. Because the shape and size of ice crystals is influenced by the G-O sheets, different additives (ethanol, cellulose nanofibers, and chitosan) that can form hydrogen bonds with H<SUB>2</SUB>O were tested and found to affect the interaction between the G-O and formation of ice crystals, producing ice crystals with different shapes. A G-O/chitosan aerogel with a spiral pattern was also obtained. After chemical reduction of G-O, our aerogel exhibited elasticity and absorption capacity superior to that of graphene aerogels with “traditional” pore structures made by conventional freeze-casting. This methodology can be expanded to many other configurations and should widen the use of G-O (and reduced G-O and “graphenic”) aerogels.</P> [FIG OMISSION]</BR>

        Transarterial Chemoembolization Using Gelatin Sponges or Microspheres Plus Lipiodol-Doxorubicin versus Doxorubicin-Loaded Beads for the Treatment of Hepatocellular Carcinoma

        Yi-Sheng Liu,Ming-Ching Ou,Yi-Shan Tsai,Xi-Zhang Lin,Chien-Kuo Wang,Hong-Ming Tsai,Ming-Tsung Chuang 대한영상의학회 2015 Korean Journal of Radiology Vol.16 No.1

        To retrospectively compare treatment of hepatocellular carcinoma (HCC) with transarterial chemoembolization (TACE) using gelatin sponges or microspheres plus lipiodol-doxorubicin vs. doxorubicin-loaded drug-eluting beads (DEB). A total of 158 patients with HCC received TACE from November 2010 to November 2011 were enrolled in this study, including 64 (40.5%) received TACE with lipiodol-doxorubicin and gelatin sponges (group A), 41 (25.9%) received TACE with lipiodol-doxorubicin and microspheres (group B), and 53 (33.5%) received TACE with doxorubicin-loaded DEB (group C). Tumor response and adverse events (AEs) were evaluated. No significant difference was found at baseline among the three groups. The doxorubicin dosage in group C wassignificantly (p < 0.001) higher compared to the dose used in groups A or B (median, 50 mg vs. 31 mg or 25 mg). Significantly (p < 0.001) more patients in group C achieved complete response compared to those in groups A or B (32.1% vs. 6.3% or 2.4%). Significantly (p < 0.001) less patients in group C had progressive disease compared to those in groups A or B (34.0% vs. 57.8% or 68.3%). Minor AEs were more common in groups A and B compared to group C, with rates of 54.7%, 34.1%, and 5.7%, respectively. In patients with HCC, TACE with DEB offers better safety and efficacy profiles compared to either TACE with gelatin sponges or TACE with microspheres.

      • Prognostic Significance of α5β1-integrin Expression in Cervical Cancer

        Wang, Hua-Yi,Chen, Zhe,Wang, Zhu-Hui,Wang, Hong,Huang, Li-Ming Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

        The purpose of this study was to evaluate the association of expression of ${\alpha}5{\beta}1$-integrin with clinicopathologic features and prognosis in cervical cancer. Levels of ${\alpha}5{\beta}1$-integrin in normal cervical mucosa and cervical cancer tissue were detected with immunohistochemistry. Survival analysis by the Kaplan-Meier method was performed to assess prognostic significance. ${\alpha}5{\beta}1$-integrin expression was detected in 84.6% (143/169) cervical cancer samples, significantly different from that in normal cervical mucosa (P < 0.05). Positive expression rates of ${\alpha}5{\beta}1$-integrin in patients with poor histologic differentiation, lymph node metastasis, and recurrence were elevated. Using Kaplan-Meier analysis, a comparison of survival curves of low versus high expression of ${\alpha}5{\beta}1$-integrin revealed a highly significant difference in human cervical cancer cases (P < 0.05), suggesting that overexpression of ${\alpha}5{\beta}1$-integrin is associated with a worse prognosis.The ${\alpha}5{\beta}1$-integrin promotes angiogenesis and associates with lymph node metastasis, vascular invasion and poor prognosis of cervical cancer. The current study indicated that ${\alpha}5{\beta}1$-integrin may be an independent prognostic factor for cervical cancer patients.

Creatine phosphokinase(CK) content is significantly get lower after trial in KRG group, and significantlower than placebo group. Conclusion: According to the criterion in the test scheme, the result shows that KRG is helpful onrelieving physical fatigue.

      • Study on knee joint injury and rehabilitation training of traditional Chen style Tai Chi practicers

        ( Wang Ming-yi ),( Kang Tao ) 한국융합과학회 2022 한국융합과학회 국제학술대회자료집 Vol.2022 No.0

        Background The purpose of this study was to further investigate the causes of knee injuries in tai jiquan athletes and to propose a rehabilitation training program based on the characteristics of traditional Chen Tai Chi and to summarize the application experience. Subjects and Methods Seventy patients with knee injuries were included in a screening study using the single-leg squat test (SLS test) and the McMurray test. They were randomly divided into a training group and a control group. The training group underwent rehabilitation training (Chen-style Tai Chi) under the guidance of a Tai Chi instructor for three months, and the control group did not receive any training instruction. The general characteristics of the patients before and after training were evaluated for knee function using the Knee Injury Rating Scale, which confirmed the good therapeutic effect of Chen-style Tai Chi on patients with osteoarthritis of the knee. RESULTS Before the rehabilitation training, the severity of injury was basically the same in both groups. At the end of the training, the training group scored significantly higher than the control group (P<0.05). The knee function score in the training group improved to excellent. which indicates the Tai Chi training played a significant role in restoring and improving knee joint function. Conclusion Attention to rehabilitation training of Tai Chi not only will not damage the knee joint, but also can reduce the chance and severity of knee injury in traditional Chen-style Tai Chi and improve the function of the knee joint. Specific recommendations are as follows: pay attention to warm-up exercises, pay attention to functional training of the knee joint, pay attention to rehabilitation factors such as relaxation and massage.
