Objective: This study aimed to investigate whether the miR-198 expression level is related to clinicopathological factors and prognosis of esophageal cancer. Methods: MicroRNA was extracted from esophageal cancer patients who underwent surgery for assessment using the Taqman@ MicroRNA assay. The correlation between miR-198 expression and clinicopathological features was analyzed, and the significance of miR-198 as a prognostic factor and its relationship with survival was determined. Results: MicroRNA-198 (miR-198) expression was higher in patients with poor prognosis than those with good prognosis (P<0.05). Kaplan-Meier analysis results showed that the miR-198 expression level had a significant correlation with survival time (P=0.030) and that patients with a higher expression of miR-198 had a shorter survival time. Cox multi-factor model analysis showed that patient prognosis (P=0.014), tumor length (P=0.040) and expression (P=0.012), and survival time had a significant correlation; the corresponding risks were 7.268, 1.246, and 3.524, respectively. Conclusion: miR-198 overexpression is involved in the poor prognosis of esophageal cancer and can be used as a biomarker for selection of cases requiring especial attention.

Lian, Li Zheng,Yun, Qi Guang,Qing, Liu Ning 대한전자공학회 1992 HICEC:Harbin International Conference on Electroni Vol.1 No.1
The study of the technique of 16QASK TCM modulation is based on the theory of trellis coding presented by G. Ungerboeck. The research demonstrates that the modulation with trellis coding may obtain 5-6 db coding gains in comparison With the conventional modulation. At last, a thought of enpanded twice channel singnals sets is suggested, and the application prospect is elaborated in this paper.
TGF-β1 Protein Expression in Non-Small Cell Lung Cancers is Correlated with Prognosis
Huang, Ai-Li,Liu, Shu-Guang,Qi, Wen-Juan,Zhao, Yun-Fei,Li, Yu-Mei,Lei, Bin,Sheng, Wen-Jie,Shen, Hong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.19
To investigate the expression intensity and prognostic significance of TGF-${\beta}1$ protein in non-small cell lung cancer (NSCLC), immunohistochemistry was carried out in 194 cases of NSCLC and 24 cases of normal lung tissues by SP methods. The PU (positive unit) value was used to assess the TGF-${\beta}1$ protein expression in systematically selected fields under the microscope with Leica Q500MC image analysis. We found that the TGF-${\beta}1$ PU value was nearly two-fold higher in NSCLC than in normal lung tissues (p=0.000), being associated with TNM stages (p=0.000) and lymph node metastases (p=0.000), but not to patient age, gender, smoking history, tumor differentiation, histological subtype and tumor location (P>0.05). Univariate analysis indicated that patients with high TGF-${\beta}1$ protein expression and lymph node metastases demonstrated a poor prognosis (both p=0.000,). Multivariate analysis showed that TGF-${\beta}1$ protein expression (RR = 2.565, p=0.002) and lymph node metastases (RR=1.874, p=0.030) were also independent prognostic factors. Thus, TGF-${\beta}1$ protein expression may be correlated to oncogenesis and serve as an independent prognostic biomarker for NSCLC.
MUTYH Association with Esophageal Adenocarcinoma in a Han Chinese Population
Kong, Feng,Han, Xue-Ying,Luan, Yun,Qi, Tong-Gang,Sun, Chao,Wang, Jue,Hou, Hua-Ying,Jiang, Yu-Hua,Zhao, Jing-Jie,Cheng, Guang-Hui Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.11
Adenocarcinoma of esophagus (AE) is a complex disease, affected by a variety of genetic and environmental factors. Much evidence has shown that the MutY glycosylase homologue (MUTYH) plays a key role in the pathogenesis of many cancers. However, there have been no reports on influence on AE in the Han Chinese population. The objective of this study was to investigate this issue. A gene-based association study was conducted using three single nucleotide polymorphisms(SNPs) reported in previous studies. The three SNPs (rs3219463, rs3219472, rs3219489) were genotyped in 207 unrelated AE patients and 249 healthy controls in a case-control study using polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP). The results revealed that the genotype distribution of rs3219472 differed between the case and control groups (OR=1.66,95%CI=1.11-2.48, P=0.012), indicating that an association may exist between MUTYH and AE. These findings support a signifcant role for MUTYH in AE pathogenesis in the Han Chinese population.
High-j Proton h11/2 and g7/2 Intruder Bands in 113In

Excited states of 113In have been populated through the heavy-ion fusion evaporation reaction 110Pd(7Li, 4n)113In. A new band with the configuration of a proton d5/2 orbital is identified. Two ΔI = 2 intruder bands, built on the πh11/2 and the πg7/2 orbitals, have been extended to spins (63/2-)ħ and (55/2+)ħ, respectively. The negative-parity πh11/2 intruder band shows a smooth increase in aligned spin, which is attributed to a strong proton-neutron interaction. The properties of the positive-parity πg7/2 band are discussed based on tilted axis cranking model calculations, and the features of the antimagnetic rotation for this band are shown after backbend. Furthermore, the contributions of the two-shears-like mechanism, the neutron (gd)ν shell and the core rotation are investigated for the positive-parity πg7/2 band.
