Rong-Hua He,Hong-Xu Li 대한수학회 2013 대한수학회보 Vol.50 No.1

By using some existence theorems of maximal elements for a family of set-valued mappings involving a better admissible set-valued mapping under noncompact setting of FC-spaces, we present some non- empty intersection theorems for a family {Gi}i∈I in product FC-spaces. Then, as applications, some new existence theorems of equilibrium for a system of generalized vector equilibrium problems are proved in product FC-spaces. Our results improve and generalize some recent results.

He, Jian-Rong,Xi, Jing,Ren, Ze-Fang,Qin, Han,Zhang, Ying,Zeng, Yi-Xin,Mo, Hao-Yuan,Jia, Wei-Hua Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12

Purpose: Complement receptor 1 (CR1) is induced by Epstein-Barr virus (EBV) and may be a potential biomarker of nasopharyngeal carcinoma (NPC). We conducted the present study to evaluate the association of CR1 expression with clinicopathological features and prognosis of NPC. Methods: We enrolled 145 NPC patients and 110 controls. Expression levels of CR1 in peripheral blood mononuclear cells (PBMCs) were detected using quantitative real-time PCR and associations with clinicopathological features and prognosis were examined. Results: CR1 levels in the NPC group [3.54 (3.34, 3.79)] were slightly higher than those in the controls [3.33 (3.20, 3.47)] (P<0.001). Increased CR1 expression was associated with histology classification (type III vs. type II, P=0.002), advanced clinical stage (P=0.003), high T stage (P=0.017), and poor overall survival (HR, 4.89; 95% CI, 1.23-19.42; P=0.024). However, there were no statistically significant differences in CR1 expression among N or M stages. Conclusion: These findings indicate that CR1 expression in PBMCs may be a new biomarker for prognosis of NPC and a potential therapeutic target.

Hua Guo,Zheng-Wei Xu,Bao-Rong He,Ding-Jun Hao,Wei-Guo Bian 한국조직공학과 재생의학회 2014 조직공학과 재생의학 Vol.11 No.5

A well-defined three-dimensional (3-D) reconstruction of bone-cartilage transitional structures is crucial for the osteochondral restoration. This paper presents an accurate, computationally efficient and semi-automated algorithm for the alignment and segmentation of two-dimensional (2-D) serial to construct the 3-D model of bonecartilage transitional structures. Entire system includes the following five components: (1) image harvest, (2) image registration, (3) image segmentation, (4) 3-D reconstruction and visualization, and (5) evaluation. A computer program was developed in the environment of Matlab for the semi-automatic alignment and automatic segmentation of serial sections. Semi-automatic alignment algorithm based on the position’s cross-correlation of the anatomical characteristic feature points of two sequential sections. A method combining an automatic segmentation and an image threshold processing was applied to capture the regions and structures of interest. SEM micrograph and 3-D model reconstructed directly in digital microscope were used to evaluate the reliability and accuracy of this strategy. The morphology of 3-D model constructed by serial sections is consistent with the results of SEM micrograph and 3-D model of digital microscope.

A New Large-Scale Plane-Strain Permeameter for Gravelly Clay Soil under Stresses

Yu-Hua Zou,Qun Chen,Chang-Rong He 대한토목학회 2013 KSCE JOURNAL OF CIVIL ENGINEERING Vol.17 No.4

A large-scale plane-strain permeameter was designed to investigate the hydraulic characteristics of gravelly clay base soil and a filter under various stresses and different water heads. The apparatus provides a specimen size about 80 cm long, 40 cm wide and 40cm high. It is equipped with a horizontal and vertical loading system with capacities of 1000 kN in the horizontal direction and 2000kN in the vertical direction and a water pressure system which can provide water head up to 300 m. The components of the planestrain permeameter are described in detail in this paper. The performance of the permeameter is demonstrated through a group of tests on specimens combining gravelly clay soil and a filter.

A Density Functional Study of Furofuran Polymers as Potential Materials for Polymer Solar Cells

Xiao-Hua Xie,Wei Shen,Rong-Xing He,Ming Li 대한화학회 2013 Bulletin of the Korean Chemical Society Vol.34 No.10

The structural, electronic, and optical properties of poly(3-hexylthiophene) (P3HT) have been comprehensively studied by density functional theory (DFT) to rationalize the experimentally observed properties. Rather, we employed periodic boundary conditions (PBC) method to simulate the polymer block, and calculated effective charge mass from the band structure calculation for describing charge transport properties. The simulated results of P3HT are consistent with the experimental results in band gaps, absorption spectra, and effective charge mass. Based on the same calculated methods as P3HT, a series of polymers have been designed on the basis of the two types of building blocks, furofurans and furofurans substituted with cyano (CN) groups, to investigate suitable polymers toward polymer solar cell (PSC) materials. The calculated results reveal that the polymers substituted with CN groups have good structural stability, low-lying FMO energy levels, wide absorption spectra, and smaller effective masses, which are due to their good rigidity and conjugation in comparison with P3HT. Besides, the insertion of CN groups improves the performance of PSC. Synthetically, the designed polymers PFF1 and PFF2 are the champion candidates toward PSC relative to P3HT.

Neuron Discharge and c-Fos Expression in the Nucleus of the Solitary Tract Following Electroacupuncture at Acupoints of the Yangming Stomach Meridian of Foot

Jun-Feng He,Jie Yan,Jiang-Shan Li,Jian-Hua Liu,Chao Wang,Xiao-Rong Chang,Ya-Ting Qu 사단법인약침학회 2013 Journal of Acupuncture & Meridian Studies Vol.6 No.2

The nucleus of the solitary tract (nucleus tractus solitarii; NTS) is a primary center for both visceral afferents and somatic afferents. Previous experiments have demonstrated that the NTS is closely connected to the stomach and acupoints in the Yangming Stomach Meridian of Foot (ST Meridian). In this study, extracellular recording and immunochemistry methods were used to analyze the discharge of neurons and c-Fos protein expression in the NTS following acupuncture at different acupoints and a nonacupoint. A total of 104 discharging neurons were detected in the NTS of 52 rats, of which 86 provided complete data. After acupuncture at Sibai (ST 2), Zusanli (ST 36), Neiting (ST 44), Quanliao (SI 18), and the nonacupoint, the neuron response rate in the NTS was 65.12%, 51.16%, 46.51%, 34.88% and 31.40% respectively. For neuron response rate, there was a significant difference among Sibai (ST 2), Zusanli (ST 36), Neiting (ST 44), Quanliao (SI 18), and the nonacupoint (p < 0.01 or p < 0.05). In the other 48 rats, the number of c-Fos immunoreactive neurons in the NTS by electroacupuncture (EA) at Sibai (ST 2) group was significantly higher than that EA at other acupoints and the nonacupoint (p < 0.05 or p < 0.01). EA at both Zusanli (ST 36) and Neiting (ST 44) increased c-Fos immunoreactive neurons significantly over EA at Quanliao (SI 18) and the nonacupoint (p < 0.05 or p < 0.01), while there was no difference between EA at Quanliao (SI 18) and the nonacupoint group (p > 0.05). The experiments demonstrated that the afferent convergence in NTS are different by body surface points stimulus, which suggests that the NTS might be a primary center in the central nervous system receiving acupoints stimulus from the ST Meridian.

Peng Du,Ying Hua Ling,Xian Chun Sang,Fang Ming Zhao,Rong Xie,Zheng Lin Yang,Guang Hua He 한국유전학회 2009 Genes & Genomics Vol.31 No.2

A mutant, which derived from the restorer line Jinhui10 treated with EMS, showed completely yellow green leaves, and it had low chlorophyll content and poor agronomic characteristics during the growing stage. The F1 plants from the cross between normal × the mutant showed normal green leaves, and the segregation ratio of normal to yellow green leaves was 3:1 in F2 population. It indicated that the trait was controlled by a single recessive nuclear gene, temporarily designated as ygl3. The gene ygl3 was mapped between RM468 and RM3684 with genetic distances 8.4 cM and 1.8 cM on chromosome 3. This result would be used as genetic information for fine mapping and map-based cloning of ygl3 gene.

Modelling the Construction of a High Embankment Dam

Qun Chen,Yu-Hua Zou,Min Tang,Chang-Rong He 대한토목학회 2014 KSCE Journal of Civil Engineering Vol.18 No.1

Appropriate layer quantity has been considered to model the sequential construction of a high embankment dam over 300 m and its effect on the predicted settlement of the 314 m high Shuangjiangkou dam has been discussed. The simulation results have demonstrated that at least 25 layers are required to accurately model the stage construction of a high embankment dam over 300 m. The stress and deformation within the dam and the foundation during the dam construction and reservoir filling have been simulated using finite element analysis. Saturated-unsaturated seepage theory is used to analyse the transient seepage field in the dam and in the foundation. Two different cases about the construction and the operation are modelled. One involves gradual reservoir filling after the completion of sequential construction, whereas the other involves sequential construction and reservoir impounding by several interleaved stages. The simulation results for both cases have been compared and discussed.
