연구목적 : 정신분열병의 환각이 문화사회의 특성에 따라 어떤 차이가 나는지를 확인하고 그 의미를 문화정신의 학적 견지에서 고찰해보고자 이 연구를 시행하였다. 방 법 : Shanghai와 서울의 정신분열병 환자를 대상으로 환각의 형태, 내용, 주제 등에 관한 비교문화적인 조사연구를 하였다. Shanghai Mental Health Center, 국립서울정신병원, 한양대학교병원에 입원하고 있는 환자중 DSM-Ⅳ 진단기준으로 정신분열병의 진단이 확정된 환자 가운데 입원한지 1개월에서 6개월 이내인 환자를 대상으로 사전에 성별, 연령, 교육연한, 발병기간 임상아형, 등 5개 변인을 통제하여 조사대상을 선정하였다. 조사대상이 된 환자는 396명(Shanghai 182명, 서울 214명)이었다. 이중 환각이 확인된 환자 231명(Shanghai101명, 서울 130명)을 최종 연구대상으로 하였다. 결 과 : 환각의 형태에서는 양 집단 차이가 없었으나 환각의 내용이 양 집단에서 차이를 보였다. 즉 Shanghai에서는 정치적인 내용이, 서울에서는 초자연적/종교적 내용이 많았다. 결 론 : 환각의 주제나 내용은 망상과 긴밀하게 연관이 되어 있다는 점, 그리고 사회문화적 상황의 영향을 다분히 받고 있음을 알 수 있었다. Objective : The types, contents and major themes of schizophrenic hallucinations in Shanghai and Seoul were compared for evaluating cultural differences and connotation. Methods : Among the schizophrenic inpatients of Shanghai Mental Health Center in Shanghai and National Seoul Mental Hospital and Hanyang University Hospital in Seoul, 396 cases(182 cases in Shanghai, 214 cases in Seoul) were selected by two ways: a) five staged stratified random sampling of sex, age, education, clinical subtype and onset year, b) cases who have admitted for one to six months in their last admission. Among them, 231 cases(55.39% in Shanghai, 60.83% in Seoul) confirmed to have hallucinations were the final subjects of study. Results : Frequencies in types of hallucination were not different between the two groups. However, contents and major themes were different: Political themes and related contents were dominant in Shanghai cases, and supernatural and religious themes and related contents were dominant in Seoul cases. Conclusion : It was concluded that contents and themes of hallucinations were closely related to the delusional contents and themes, and such patterns were considerably influenced by so-ciocultural characteristics.

Yong-Liang ZHANG,Zhi-Qin ZHANG,Gang XIAO,Rui-Dong WANG,Xia HE 제어로봇시스템학회 2015 제어로봇시스템학회 국제학술대회 논문집 Vol.2015 No.10

Monitoring system has become one of the most important means for perimeter intrusion prevention. But most of existing monitoring systems are passive surveillance. In this paper, we propose a method to implement active perimeter intrusion detection by identifying human targets in video images captured by monitoring system. In order to enhance the robustness of detecting postures of human targets, this paper introduces Fourier Descriptor (FD) and Histogram of Oriented Gradients (HOG) to realize an effective detection of human bodies with multiple postures captured by fixed cameras. The experiment results confirm that the proposed algorithm has higher recognition rate for detecting human targets with walking, climbing, and jumping postures, and sufficiently meets the requirements of perimeter intrusion detection.

Yong-Liang Zhang,Wen Zhang,Gang Xiao,Jia-Fa Mao,Shan-Shan Huang,Xiao-Wei Zheng 제어로봇시스템학회 2012 제어로봇시스템학회 국제학술대회 논문집 Vol.2012 No.10

Image segmentation is an important and classic problem in image processing and computer vision. Thresholding is applied to many fields, because of its less computation and stable performance. The key of thresholding method is to determine the adaptive threshold. In order to segment biological image effectively, a new adaptive thresholding method is proposed. First, two dimension minimum entropy is computed based on gray-gradient co-occurrence matrix; and then the genetic algorithm is applied to encode the two-dimension threshold vector; Finally, the optimum threshold is calculated based on fitness function and uniformity measurement(UM). Experimental results show that this method has three advantages: 1) improve computational efficiency so that it can run in real time; 2) retain more object and edge information so that it can meet the practical requirement; 3) robust to the uneven distribution of light.

Objective: To observe the clinical efficacy of bevacizumab concomitant with pemetrexed in patients with advanced non-small cell lung cancer (NSCLC). Materials and Methods: A total of 72 patients were randomly divided into a combination group (pemetrexed+bevacizumab, n=36) and a pemetrexed group (n=36) and assessed for disease control (CR+PR+SD) after 4-cycles of first-line GP chemotherapy (gemcitabine+cisplatin). Clinical efficacy, progression-free survival time (PFS), overall survival time (OS), overall response rate (ORR), disease control rate (DCR) and rate of adverse responses between two groups were observed and compared. Results: ORR and DCR were 27.8% and 83.4% in combination group, and 16.7% and 69.5% in the pemetrexed group, respectively, but there were no significant differences (P>0.05). PFS in combination group and pemetrexed group were 4.6 months and 3.9 months respectively (P=0.09), whereas OS in the combination group was 14 months, evidently higher than in the pemetrexed group (11 months, P=0.004). Adverse responses in both groups included high blood pressure, bleeding, thrombocytopenia, anemia, elevated transaminase, diarrhea, vomiting and proteinuria, but there were no significant differences (P>0.05). Conclusions: Bevacizumab concomitant with pemetrexed has better clinical efficacy and safety, giving rise to prolonged survival time in patients with advanced NSCLC.

Zhang, Yu-Rong,Xu, Yong,Yang, Kuo,Liu, Ming,Wei, Dong,Zhang, Yao-Guang,Shi, Xiao-Hong,Wang, Jian-Ye,Yang, Fan,Wang, Xin,Liang, Si-Ying,Zhao, Cheng-Xiao,Wang, Fei,Chen, Xin,Sun, Liang,Zhu, Xiao-Quan,Zh Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12

Background/Aim: Six prostate cancer (PCa) susceptibility loci were identified in a genome-wide association study (GWAS) in populations of European decent. However, the associations of these 6 single-nucleotide polymorphisms (SNPs) with PCa has remained tobe clarified in men in Northern China. This study aimed to explore the loci associated with PCa risk in a Northern Chinese population. Methods: Blood samples and clinical information of 289 PCa patients and 288 controls from Beijing and Tianjin were collected. All risk SNPs were genotyped using polymerase chain reaction (PCR)-high resolution melting curve technology and gene sequencing. Associations between PCa and clinical covariates (age at diagnosis, prostate-specific antigen [PSA], Gleason score, tumor stage, and level of aggressiveness) and frequencies of alleles and genotypes of these SNPs were analyzed using genetic statistics. Results: Among the candidate SNPs, 11p15 (rs7127900, A) was associated with PCa risk (P = 0.02, odds ratio [OR] = 1.64, 95% confidence interval [CI] = 1.09-2.46). Genotypes showed differences between cases and controls on 11p15 (rs7127900, A), 11q13 (rs7931342, T), and HNF1B (rs4430796, A) (P = 0.03, P = 0.01, and P = 0.04, respectively). The genotype TG on 11q13 (rs7931342, T) was positively associated with an increased Gleason score (P = 0.04, OR = 2.15, 95% CI = 1.02-4.55). Patients carrying TG on 17q24 (rs1859962, G) were negatively associated with an increased body mass index (BMI) (P = 0.03, OR = 0.44, 95% CI = 0.21-0.92) while those with AG on HNF1B (rs4430796, A) were more likely to have PSA increase (P = 0.002). Conclusion: Our study suggests that 11p15 (rs7127900, A) could be a susceptibility locus associated with PCa in Northern Chinese. Genotype TG on 11q13 (rs7931342, T) could be related to an increased Gleason score, AG on HNF1B (rs4430796, A) could be associated with PSA increase, and TG on 17q24 (rs1859962, G) could be negatively associated with an increased BMI in Chinese men with PCa.

The alfalfa plant bug Adelphocoris lineolatus (Goeze) (Hemiptera: Miridae), a serious pest of several agricultural crops, is extremely attracted by flowering plants to perform season host switching. Generally, chemoreception of A. lineolatus plays a crucial role in detecting food sources, locating mates and oviposition sites. In addition, odorant carrier proteins are believed to participate in the initial chemical communication and perception in insects. In this work, we identified 31 putative odorant carrier protein genes from the antennal transcriptomes of A. lineolatus, including 17 new odorant binding proteins (OBPs), 10 new chemosensory proteins (CSPs) and four Niemann-Pick type C2 proteins (NPC2s). Phylogenetic analysis demonstrated that the OBP and CSP genes from four mirid bug species (A. lineolatus, Adelphocoris suturalis, Apolygus lucorum and Lygus lineolaris) had a relatively close evolutionary relationship. Regular patterns and key conserved motifs of OBPs and CSPs in Hemiptera insects are also identified by using Multiple EM for Motif Elicitation (MEME) tool. Tissue expression profiles analysis showed that nine of the 17 OBPs, 10 CSPs and two of the four NPC2s were primarily or uniquely expressed in the adult antennae suggesting their putative roles in chemoreception. Our study provides the first insight into the roles of odorant carrier proteins in chemoreception of A. lineolatus, which will help to facilitate biological functions of odorant carrier proteins and develop novel insect behavioral regulation strategy

Zhang-Zhang He,Jie Luo,Lian-You Gui,Deng-Ke Hua,Tian-Hua Du,Fu-Lian Wang,Peng Liang,Yong-Fang Shi,Xuan Yang 한국응용곤충학회 2019 Journal of Asia-Pacific Entomology Vol.22 No.3

Previous work reveals that the adult Chinese citrus fly, Bactrocera minax (Enderlein), emerges from the ground in citrus orchards and presumably disperses to alternate food sources in neighboring shrubs and trees, where it stays and becomes reproductively mature, and then later returns to the orchard to lay eggs. We investigated the trajectories of early emerged adult Chinese citrus flies, which were tracked with portable harmonic radar in 2013, 2014, 2015, and 2016 in four different habitats in Hubei province of China that presumably provided food sources for adults. This study we investigated whether early emerged adult Chinese citrus flies migrate into forests. A total of 47 adults were tracked following release in a citrus orchard. Our results showed that a total of 33 adults released in a citrus orchard flew into the forest, and 14 adults that disappeared during the tracking process in the citrus orchard. A total of 10 adults (in 2014) that were tracked and released in the forest flew to the forest. Of the adult flies investigated, 54.5% flew directly into the forest, while the remaining 45.5% finally arrived in the forest after repeatedly adjusting their trajectories. When there were Castanea mollissima Blume (Fagaceae) in the surrounding forest, the proportion of frequency of adult landing on the plant represented 58.3% and 88.5% of landing on all species in 2014 and in 2015, respectively. We conclude that early emerged adult Chinese citrus flies in the mosaic-type citrus orchard of the hilly terrain landform dispersed into adjacent forest.

Zhi-Hai Ni,Xian-Jun Liang,Jing-Gang Mo,Yi Zhang,Jian-Hua Liang,Yu-Sha Yang,Yong Zhou,Zhao-Hua Li,Jian-Liang Zhang,Yin-Lu Ding,Peng Zhang,Jin-Qing Wang 한국유전학회 2015 Genes & Genomics Vol.37 No.11

We aim to investigate the correlations of hypoxia inducible factor-1a (HIF-1a) C1772T (rs11549465) and G1790A (rs11549467) gene polymorphisms with digestive tract cancers. A sum of 267 digestive tract cancers patients were hospitalized in Taizhou Central Hospital of Zhejiang Province as case group between December 2012 and December 2014. Additionally, 275 healthy people who had a physical examination in our hospital at the same time were selected as control group. Polymerase chain reaction-restriction fragment length polymorphism was utilized for detecting allele and genotype frequency of different locus in case and control group. Meta-analysis was performed using Comprehensive Metaanalysis 2.0 (Biostat Inc., Englewood, New Jersey, USA). Our result showed statistical significance only exists in family history of cancer between case and control group (P\0.05). Both C1772T (rs11549465) and G1790A (rs11549467) polymorphisms showed positive correlations with an increasing risk of digestive tract cancers. The frequencies of TT genotype of C1772T (rs11549465) and GA, AA genotypes of G1790A (rs11549467) polymorphisms in case group were evidently higher compared with the controls (all P\0.05). Besides, the comparison of allele and dominant models of HIF-1a C1772T (rs11549465) and G1790A (rs11549467) between two groups showed a significant difference (all P\0.05). Meta-analysis results further confirmed that the onset risk of digestive tract cancers may be improved under allele and dominant models of HIF-1a C1772T (rs11549465) and G1790A (rs11549467) (all P\0.05). Single nucleotide polymorphisms of HIF-1a C1772T (rs11549465) and G1790A (rs11549467) may play a role in development of digestive tract cancers.

Yong Zhang,Shuquan Liang,Athar Javed,Dikai Guan 대한금속·재료학회 2013 METALS AND MATERIALS International Vol.19 No.3

The effect of pass deformation in rolling processes on the microstructure, corrosion resistance and electrochemical activity of Al-Mg-Bi-Sn-Ga-In alloy anodes operated in an alkaline solution (85 °C, 5 mol·L−1 NaOH with addition of NaSnO3) with current density of 800 mA·cm−2 was investigated. To analyze the microstructure of aluminum alloy anodes, we used scanning electron microscope, transmission electron microscope and electron backscatter diffraction techniques. We also used the hydrogen evolution method and electrochemical testing techniques to investigate the corrosion and electrochemical behavior of aluminum alloy anodes. The results showed that uniform microstructures with homogeneous distribution of fine active segregated phases as well as an excellent electrochemical performance of the aluminum alloy anodes were achieved by the dynamic recrystallization under pass deformation of 40%. We found that the aluminum alloy anodes (under pass deformation of 40%) had the lowest hydrogen evolution rate (0.092 mL·min−1·cm−2)and the most negative electrode potential (−1.585 V).

Liang Chai,Jinfang Zhang,Wannakuwattewaduge Gerard Dilantha Fernando,Haojie Li,Xiaoqin Huang,Cheng Cui,Jun Jiang,Benchuan Zheng,Yong Liu,Liangcai Jiang 한국식물병리학회 2021 Plant Pathology Journal Vol.37 No.2

Blackleg is a serious disease in Brassica plants, causing moderate to severe yield losses in rapeseed worldwide. Although China has not suffered from this disease yet (more aggressive Leptosphaeria maculans is not present yet), it is crucial to take provisions in breeding for dis- ease resistance to have excellent blackleg-resistant cul- tivars already in the fields or in the breeding pipeline. The most efficient strategy for controlling this disease is breeding plants with identified resistance genes. We selected 135 rapeseed accessions in Sichuan, including 30 parental materials and 105 hybrids, and we deter- mined their glucosinolate and erucic acid content and confirmed 17 double-low materials. A recently devel- oped single-nucleotide polymorphism (SNP) marker, SNP_208, was used to genotype allelic Rlm1/rlm1 on chromosome A07, and 87 AvrLm1-resistant materials. Combined with the above-mentioned seed quality data, we identified 11 AvrLm1-resistant double-low rapeseed accessions, including nine parental materials and two hybrids. This study lays the foundation of specific R gene-oriented breeding, in the case that the aggressive Leptosphaeria maculans invades and establishes in Chi- na in the future and a robust and less labor consuming method to identify resistance in canola germplasm.
