최근 몇 년 회귀 주류와의 융합 교육 정책 하에 대만의 특수 교육 학교는 예전과 다른 큰 변화에 직면해 있다. 완전 융합 이념의 실시 또 심신장애학생을 주류교육으로 회귀해야 한다는 것을 제창함으로, 특수교육학교는 인원이 감소하게 됐다. 특수교육 학교는 신입생 모집이 부족한 상황에서 학교 교사들의 관점이 교장의 지도에 대해 보는 관점이 어떻게 다른가? 그에 대한 요구도 다른가? 본 연구는 두 인자 변의 수 분석이 대만 지능 장애와 감각 장애 종류의 특수 교육 학교 교장전형 리더십에 대한 연구이다. 실험 대상자는 8개 지능 장애종류 특수교육 학교와 5개 감각 장애종류 특수 교육 학교의 259명의 교사이고 그들이 특수교육학교 교장 리더에 대한 건의를 제출했다. In recent years, the domestic special education schools have faced with huge changes under the mainstream and inclusive education policies for the implementation of the full-inclusive and the mainstream education for the students with impairment. That causes the special education schools to reduce classes. Under this situation, what are the teachers?fdifferent views about the principal? What are their needs? The study was undertaken through two-way ANOVA to explore principals?ftransformational leadership between the schools for the mentally retarded and for the sensory impaired. 259 teachers were selected from 8 schools for the mentally retarded and 5 sensory impairment special education schools. Based upon the findings, the implications for practice were proposed.

Wang, Hong-Li,Liu, Mei-Mei,Ma, Xin,Fang, Lei,Zhang, Zong-Feng,Song, Tie-Fang,Gao, Jia-Yin,Kuang, Ye,Jiang, Jing,Li, Lin,Wang, Yang-Yang,Li, Pei-Ling Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

Previous studies have demonstrated that JMJD2A is a potential oncogene and is overexpressed in human tumors. However, its role in the endometrial carcinoma remains largely unknown. In this study, we discovered that JMJD2A was overexpressed in endometrial carcinoma, using immunohistochemistry, quantitative realtime polymerase chain reaction, and western blotting. Downregulation of JMJD2A led to reduced endometrial carcinoma RL95-2 and ISK cell proliferation, invasion and metastasis as asessed with cell counting kit-8, cell migration and invasive assays. Collectively, our results support that JMJD2A is a promoter of endometrial carcinoma cell proliferation and survival, and is a potential novel drug target.

Cheng Mei-Fang,Guo Yue Leon,Yen Ruoh-Fang,Wu Yen-Wen,Wang Hsiu-Po 대한영상의학회 2023 Korean Journal of Radiology Vol.24 No.6

Objective: To investigate whether the levels of inflammation detected by 18F-fluorodeoxyglucose (FDG) positron emission tomography (PET)/computed tomography (CT) can predict disease relapse in immunoglobulin G4-related disease (IgG4-RD) patients receiving standard induction steroid therapy. Materials and Methods: This prospective study analyzed pretherapy FDG PET/CT images from 48 patients (mean age, 63 ± 12.9 years; 45 males and 3 females) diagnosed with IgG4-RD between September 2008 and February 2018, who subsequently received standard induction steroid therapy as the first-line treatment. Multivariable Cox proportional hazards models were used to identify the potential prognostic factors associated with relapse-free survival (RFS). Results: The median follow-up time for the entire cohort was 1913 days (interquartile range [IQR], 803–2929 days). Relapse occurred in 81.3% (39/48) patients during the follow-up period. The median time to relapse was 210 days (IQR, 140–308 days) after completion of standardized induction steroid therapy. Among the 17 parameters analyzed, Cox proportional hazard analysis identified whole-body total lesion glycolysis (WTLG) > 600 on FDG-PET as an independent risk factor for disease relapse (median RFS, 175 vs. 308 days; adjusted hazard ratio, 2.196 [95% confidence interval: 1.080–4.374]; P = 0.030). Conclusion: WTLG on pretherapy FDG PET/CT was the only significant factor associated with RFS in IgG-RD patients receiving standard steroid induction therapy.

Zhao, Yu-Mei,Wang, Jian-Tao,Liu, Jing,Wang, Ju,Wang, Hong-Li,Liu, Pei-Fang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.12

Objective: To compare the mammogarphic appearance between breast cancer patients aged <40 and ${\geq}40$ years. Methods: Needle localization and biopsy of suspicious mammographic lesions identified 1,959 breast carcinomas in a single institution from Jun 2012 to Apr 2013. According to the age, we divided patients into two groups: <40 and ${\geq}40$ years old, and analyzed mammographic appearance separately. Results: Young patients had 44.2% foci with calcification, but old patients only had 39.4% (P<0.001). In younger group, the ratios of cases according to mass density were 41.8% or higher, 58.2% equivalent and lower. In older group, the ratios were 55.5 % and 44.5%, respectively. There were statistical differences between high density and others (P<0.05). The ratios of cases according to mass margin were 13.9% circumscribed and microlobulated, 86.1% indistinct and spiculated in the younger group, as compared to 6.5% and 93.5%, respectively, in the older group (P<0.05). Conclusions: Mammographic findings differ between young and old patients with breast cancer, for example regarding mass density, mass margin and microcalcification ratios.

Mitochondrial-Targeted Polyethylenimine Functionalized Graphene Oxide Nanocarrier and Its Anti-Tumor Effect on Human Lung Carcinoma Cells

Mei Jin,Zhiming Liu,Wen Zhang,Haixin Dong,Fang Zhou,Jianfeng Yu,Xinpeng Wang,Zhouyi Guo 성균관대학교(자연과학캠퍼스) 성균나노과학기술원 2015 NANO Vol.10 No.8

Graphene oxide nanosheet (NGO) was covalently functionalized with positively charged, branched polyethylenimine (bPEI) via an amide bond, coated with serum proteins by electrostatic interaction. Operating as a newly fashioned, multifunctional nanocarrier, the processed NGO showed promise for use in combined gene therapy, chemotherapy, photothermal therapy, bioimaging and as a biosensor of cancer cells. Our current research is focused on the systematic studies of mechanisms of cancer cellular uptake, subcellular location, cytotoxicity and the cellular exclusion of the NGO–bPEI nanocarriers. It was observed that NGO–bPEI accumulated in the mitochondria and that long-term retention of NGO–bPEI led to a decrease in mitochondrial membrane potential while levels of reactive oxygen species increased. The mitochondrial effects associated with long-term retention of NGO–bPEI have potential as a synergistic enhancer of the cytotoxic effects of anti-cancer drugs or genes in human lung carcinoma (A549) cells. This work demonstrated the utility of NGO–bPEI-based multifunctional nanocarriers while detailing the mechanism at the cellular level and providing guidance for further research in cancer therapy.

DNAmethylation plays a key role in gene regulation and phenotype variation in many organisms. The aimof thisstudy was to survey the frequency and variation of cytosine methylation at CCGG sequences in adult male andfemale planthoppers Sogatella furcifera, a major rice pest in Asia, and to determine the occurrence ofmethylationchanges associatedwith sexual dimorphismusingmethylation-sensitive amplification polymorphism. 1131DNAfragments including CCGG siteswere amplified using 36 pairs of selective primers: about 191methylated bandswere identified. Inmale planthoppers,we got a total of 581 bands, including 40 fully-methylated bands, 65 hemimethylatedbands and 476 none-methylated bands, so the fully-methylated ratio, hemi-methylated ratio andtotal methylated ratio were 6.88%, 11.19% and 18.07%, respectively. In the female planthopper, there were atotal of 550 bands, including 44 fully-methylated bands, 42 hemi-methylated bands and 464 none-methylatedbands. The fully-methylated ratio was 7.64% in female planthoppers, which was slightly higher than in themale planthoppers, however, the hemi-methylated ratio was lower (8.00%) in the female compared with themale planthopper. Altogether, 46 DNA bands displayed variable cytosine methylation patterns between maleand female samples: 20 of themoccurred only inmale samples and 26 only in female samples. Thus, the genomemethylation patterns are different between male and female adults. The results suggest that DNA methylationmight be related to sexual differentiation and development in S. furcifera.

Fangchinoline Inhibits Cell Proliferation Via Akt/GSK-3beta/cyclin D1 Signaling and Induces Apoptosis in MDA-MB-231 Breast Cancer Cells

Wang, Chang-Dong,Yuan, Cheng-Fu,Bu, You-Quan,Wu, Xiang-Mei,Wan, Jin-Yuan,Zhang, Li,Hu, Ning,Liu, Xian-Jun,Zu, Yong,Liu, Ge-Li,Song, Fang-Zhou Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.2

Fangchinoline (Fan) inhibits cell proliferation and induces apoptosis in several cancer cell lines. The effects of Fan on cell growth and proliferation in breast cancer cells remain to be elucidated. Here, we show that Fan inhibited cell proliferation in the MDA-MB-231 breast cancer cell line through suppression of the AKT/Gsk-3beta/cyclin D1 signaling pathway. Furthermore, Fan induced apoptosis by increasing the expression of Bax (relative to Bcl-2), active caspase 3 and cytochrome-c. Fan significantly inhibited cell proliferation of MDA-MB-231 cells in a concentration and time dependent manner as determined by MTT assay. Flow cytometry analysis demonstrated that Fan treatment of MDA-MB-231 cells resulted in cell cycle arrest at the G1 phase, which correlated with apparent downregulation of both mRNA and protein levels of both PCNA and cyclin D1. Further analysis demonstrated that Fan decreased the phosphorylation of AKT and GSK-3beta. In addition, Fan up-regulated active caspase3, cytochrome-c protein levels and the ratio of Bax/Bcl-2, accompanied by apoptosis. Taken together, these results suggest that Fan is a potential natural product for the treatment of breast cancer.

Wang Shen,Lin Li-mei,Wu Yong-ning,Fang Min,Yu Ya-qin,Zhou Jia,Gong Zhi-yong 한국식품과학회 2014 Food Science and Biotechnology Vol.23 No.5

In vitro and in vivo antihypertensive effects ofgrass carp peptides (GCP) were investigated. The aminoacid composition and the angiotensinconverting enzymeinhibitory activity were evaluated using HPLC. GCP wasadministrated to spontaneously hypertensive rats (SHRs)and Wistar Kyoto rats (WKY) by single and long-termadministration before blood pressure measurements. Plasma levels of angiotensin II (Ang II), rennin (RA), nitricoxide (NO), and plasma angiotensin I converting enzyme(ACE) activity were measured. The GCP molecular weightwas between 725 and 1,228 Da with high levels of Leu,Asp, Phe, Gly, and Pro. The in vitro IC50 value was 0.23mg/mL. GCP lowered SHR blood pressure dose and timedependently. Little change occurred in WKY. The plasmalevel of Ang II and the ACE activity decreased. SHR RAand NO concentrations in plasma increased. Theantihypertensive effect of GCP was associated with NOregulation and the rennin-angiotensin system.

Fang-Hsin Lee,Yung-Mei Yang,Hsiu-Hung Wang,Joh-Jong Huang,Shu-Chen Chang 한국간호과학회 2015 Asian Nursing Research Vol.9 No.2

Purpose: Intimate partner violence (IPV) is a serious public health issue among women. IPV victims usually seek help from hospitals, and emergency nurses are the frontline staff with whom the victims come into contact first. This study examined the conditions and patterns of IPV in southern Taiwan. Methods: From designated hospitals in Kaohsiung under the Department of Health Injury Assessment Clinic, data were collected on 497 women regarding their injury assessment for IPV reported to the Kaohsiung City Government. Results: Taiwanese survivors were older compared to immigrant survivors. Taiwanese survivors also had higher education levels compared to immigrant survivors. Taiwanese survivors had higher employment rate than immigrant survivors did. The time between IPV and medical help seeking was longer for divorced than married women. Conclusions: These results can facilitate understanding of the conditions and patterns of IPV in Taiwan, increase the awareness of nurses, especially the emergency nurses for the prevention of IPV, and increase professional competency for the provision of appropriate healthcare services to survivors of IPV.

The MDM2 SNP309T>G Polymorphism Increases Bladder Cancer Risk among Caucasians: a Meta-analysis

Wang, Huai-Gao,Wu, Qing-Yun,Zhou, Hui,Peng, Xin-Sheng,Shi, Meng-Jie,Li, Jie-Mei,Zhou, Yan-Fang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.13

Published studies have evaluated associations between the MDM2 SNP309T>G polymorphism and bladder cancer susceptibility. However, these generated inconsistent results. The aim of the present investigation was to quantify the strength of association between MDM2 SNP309T>G polymorphism and bladder cancer risk by conducting a meta-analysis. We searched PubMed and Embase for related studies that had been published in English before April 1, 2014 and associations were assessed by summarizing the odds ratios (ORs) with the corresponding 95% confidence intervals (CIs). Five case-control studies with a total of 972 cases and 1,012 controls were finally identified to be eligible for the meta-analysis. Overall, the results indicated that there was no significant association between the MDM2 SNP309T>G polymorphism and bladder cancer risk (for the allele model G vs. T: OR=1.08, 95% CI 0.85-1.36, p=0.54; for the co-dominant model GG vs. TT: OR=1.20, 95% CI 0.74-1.93, p=0.46; for the dominant model GG+GT vs. TT: OR=0.98, 95% CI 0.80-1.20, p=0.83; for the recessive model GG vs. GT+TT: OR=1.20, 95% CI 0.83-1.74, p=0.33). However, on subgroup analysis by ethnicity, significant associations were found in Caucasians in three models (for the allele model G vs. T: OR=1.41, 95% CI 1.10-1.81, p=0.006; for the co-dominant model GG vs. TT: OR=2.16, 95% CI 1.28-3.63, p=0.004; for the recessive model GG vs. GT+TT: OR=2.06, 95% CI 1.31-3.22, p=0.002). In summary, the present meta-analysis provides evidence that the genotype for the MDM2 SNP309T>G polymorphism may be associated with genetic susceptibility to bladder cancer among Caucasians.
