Purpose The extranodal natural killer (NK)/T-cell lymphoma (NKTCL) of non-upper aerodigestive tract (NUAT) was found to have clinical heterogeneity compared with NKTCL of the upper aerodigestive tract (UAT) in small scale studies. We conducted this study in a much larger cohort to analyze the clinical characteristics, prognostic factors, treatment modality, and clinical outcomes of patients with NUAT-NKTCL. Materials and Methods From January 2001 to December 2017, a total of 757 NKTCL patients were identified and included in this study, including 92 NUAT-NKTCL patients (12.2%) and 665 UAT-NKTCL patients (87.8%). Results NUAT-NKTCL patients had relatively poorer performance status, more unfavorable prognostic factors, and more advanced stage, compared with UAT-NKTCL patients. The 5-year overall survival (OS) was 34.7% for NUAT-NKTCL, which was significantly worse than UAT-NKTCL (64.2%, p < 0.001). The median OS duration was 30.9 months for NUAT-NKTCL. Multivariate analysis showed that presence with B symptoms and elevated serum lactate dehydrogenase independently predicted worse OS. International prognostic index score and prognostic index of NK lymphoma score still had prognostic values in NUAT-NKTCL, while the Ann Arbor system could not accurately predict the OS. Conclusion NUAT-NKTCL is a distinctive subtype of NKTCL in many aspects. Patients with NUAT-NKTCL have relatively poorer performance status, more unfavorable prognostic factors, more advanced stage, and poorer prognosis.

Hereditary non-polyposis Colorectal Cancer (HNPCC) is an autosomal dominant inheritance syndrome. HNPCC is the most common hereditary variant of colorectal cancer (CRC), which accounts for 2-5% CRCs, mainly due to hMLH1 and hMSH2 mutations that impair DNA repair functions. Our study aimed to identify the patterns of hMSH2 and hMLH1 mutations in Chinese HNPCC patients. Ninety-eight unrelated families from China meeting Amsterdam or Bethesda criteria were included in our study. Germline mutations in MLH1 and MSH2 genes, located in the exons and the splice-site junctions, were screened in the 98 probands by direct sequencing. Eleven mutations were found in ten patients (11%), with six in MLH1 (54.5%) and five in MSH2 (45.5%) genes. One patient had mutations in both MLH1 and MSH2 genes. Three novel mutations in MLH1 gene (c.157_160delGAGG, c.2157dupT and c.-64G>T) were found for the first time, and one suspected hotspot in MSH2 (c.1168C>T) was revealed.

The objective of this study was to establish the optimum protocol for the isolation and culture of porcine muscle satellite cells. Mononuclear muscle satellite cells are a kind of adult stem cell, which is located between the basal lamina and sarcolemma of muscle fibers and is the primary source of myogenic precursor cells in postnatal muscle. Muscle satellite cells are a useful model to investigate the mechanisms of muscle growth and development. Although the isolation and culture protocols of muscle satellite cells in some species (e.g. mouse) have been established successfully, the culture system for porcine muscle satellite cells is very limited. In this study, we optimized the isolation procedure of porcine muscle satellite cells and elaborated the isolation and culture process in detail. Furthermore, we characterized the porcine muscle satellite cells using the immunofluorecence. Our study provides a reference for the isolation of porcine muscle satellite cells and will be useful for studying the molecular mechanisms in these cells.

Purpose Capecitabine is an extensively used oral prodrug of 5-fluorouracil in treatment of colon cancer and is known to cause hand-foot syndrome (HFS). As the target enzyme for capecitabine, thymidylate synthase (TYMS) plays a key role for 5-fluorouracil metabolism and has been associated with some side effects caused by capecitabine. The aim of our study is to identify the possible genetic predictors of capecitabine-induced HFS (CAP-HFS) in Chinese colorectal cancer patients.Materials and Methods Whole exons of TYMS were sequenced for 288 extreme phenotype HFS patients, including 144 severe or early-onset (first 2 cycles) moderate HFS extreme cases and 144 extreme controls with no reported HFS. The associations between polymorphisms and CAP-HFS were analyzed using logistic regression under an additive model.Results We identified a novel risk mutation (c.1A>G, chr18:657743), was associated with severe HFS in an extreme case who was affected during the first cycle of treatment. Moreover, we identified three new variants, rs3786362, rs699517, rs2790, and two previously reported variants, 5’VNTR 2R/3R and 3′-untranslated region 6-bp ins-del, which were significantly associated with CAP-HFS (p < 0.05). In silico analysis revealed that the effect of these polymorphisms in the TYMS region on the development of HFS might not be restricted solely to the regulation of TYMS expression, but also the TYMS catalytic activity through the indirect effect on ENOSF1 expression.Conclusion This study identified new polymorphisms in TYMS gene significantly associated with CAP-HFS, which may serve as useful genetic predictors for CAP-HFS and help to elucidate the underlying mechanism of HFS.

Zhou, Qi,Jiang, Jue,Shang, Xu,Zhang, Hong-Li,Ma, Wen-Qi,Xu, Yong-Bo,Wang, Hua,Li, Miao Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.17

Background: The purpose of this study was to investigate the correlation of contrast-enhanced ultrasonographic (CEUS) features with microvessel density (MVD) in papillary thyroid carcinomas (PTCs). Materials and Methods: Contrast-enhanced ultrasonography (CEUS) was performed in 62 patients (17 men and 45 women) with PTC. Tomtec software was applied to analyze the time intensity curve of CEUS. Immunohistochemistry was performed to evaluate the level of MVD in papillary thyroid carcinoma. Then the relationship between quantitative feature and the level of MVD was analyzed using SPSS 16.0 software. Results: The mean peak intensity of PTC tissues was lower than that of peripheral thyroid parenchyma ($61.9{\pm}11.8%$ vs 100%, p<0.05). The MVDs of CD34 and CD31 antibodies staining were $38.0{\pm}6.1$ and $37.9{\pm}5.1$ respectively in 62 PTC samples. A significantly positive correlation was observed between peak intensity and MVD in PTC tissues ($P_{CD34}$<0.01, $r_{CD34}$=0.838, $P_{CD31}$<0.01, $r_{CD31}$=0.837). Conclusions: The peak intensity in CEUS could reflect the MVD in PTC tissues. Therefore, quantification of CEUS seems to be helpful for assessment of MVD in PTC tissues.

일본 애니메이션에 나타난 언령신앙(言霊信仰)에 관한 연구 - TV 애니메이션 〈나츠메 우인장(夏目友人帳)〉을 중심으로

서치린(She, Qi-Lin),최동혁(Choi, Dong-Hyuk),자오원장(Zhao, Wen-Jiang) 한국만화애니메이션학회 2021 만화애니메이션연구 Vol.- No.62

고대의 일본 사람은 세상 만물에 신령(神靈)이 존재하며, 특히 언어(言語)에서의 신령이 가지는 영력(靈力)이 사람들에게 복(福)이나 재(災)를 가져다줄 수 있다고 주장하였다. 이러한 언어에 대한 숭배는 언령신앙(言霊信仰)이라고 부른다. 상대(上代)문학의 많은 작품들이 언령신앙을 구현했거나 부응시켰는데, 이는 상대(上代)문학의 중요한 특징 중 하나가 되었다. 그러나 언령신앙에 관한 기존 연구들은 주로 초기의 문학 형식이나 문학 작품을 고찰에 그치고 있으며, 사회의 발전에 따라 언령신앙이 현대사회에서 어떻게 계속되고 구현되는지에 대한 연구는 부족하였다. 이에 본 연구는 상대(上代)문학에서 언령신앙의 특징을 기반으로 기존의 선행연구들을 정리함으로써 언령신앙과 애니메이션의 결합 가능성을 탐구하고자 하였다. 즉, 애니메이션 작품에서 언령신앙의 출현배경과 표현사례를 검토하여 ‘캐릭터의 표현’, ‘이름(名前)의 활용’과 ‘주술(呪術)과 마법의 활용’ 등 세 가지의 측면에서 TV 애니메이션 <나츠메 우인장(夏目友人帳)>에서 나타난 언령신앙의 구체적인 표현을 분석하였다. 이를 통해 애니메이션과 같은 현대 예술작품에서 언령신앙이 구현되는 구체적인 표현방법과 창작 방법을 도출하였다. 언령신앙과 같은 고대의 일본 문화나 사상을 소재로 한 애니메이션의 대표적인 표현사례를 분석한 본 연구가 다양한 고대사상과 전통문화를 이해를 돕고 많은 문화콘텐츠 분야에 활용과 발전에 기여되기를 기대한다. The ancient Japanese believed that there are gods in everything in the world. Souls and spiritual powers in language, which can bring blessings or disasters to people. This kind of worship of language is called language worship. In the early Japanese literature, there are many examples of language worship, which has become one of the important characteristics of early Japanese literature. However, the existing research on language worship mainly stays on the investigation of early literary forms or works. With the development of society, there is insufficient research on how the language worship continues and manifests in modern society. This research is based on the language worship in early Japanese literature, investigating the existing advanced research, and exploring the possibility of combining language worship with animation. Language worship is mainly manifested in three types in animation: ‘character performance’, ‘utilization of names’, and ‘utilization of spells and magic.’ This research analyzes the background and examples of the appearance of language worship in animation and analyzes language worship in the TV animation 〈Natsume"s Book of Friends〉. Through these, we learned about the examples and methods of ancient thoughts and traditional culture used in animation and other works of modern art. This research uses ancient Japanese culture or ideas such as language worship as materials to analyze representative examples of animation. It is hoped that this research can help to understand various ancient ideas and traditional cultures, and contribute to the utilization and development of cultural fields.

Li, Yang,Ma, Wen-Jun,Qi, Bao-Kun,Rokayya, Sami,Li, Dan,Wang, Jing,Feng, Hong-Xia,Sui, Xiao-Nan,Jiang, Lian-Zhou Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.6

Background: Soybean oil may protect against cancer of the breast and prostate. It may also exert beneficial influence in combination with other oils. Here, blends (20%, v/v) of sea buckthorn oil (SEBO), camellia oil (CAO), rice bran oil (RBO), sesame oil (SEO) and peanut oil (PEO) with soybean oil (SBO) were formulated. Materials and Methods: Oxidative stability (OS) and radical scavenging activity (RSA) of SBO and blends stored under oxidative conditions ($60^{\circ}C$) for 24 days were studied. By blending with different kinds oils, levels of polyunsaturated fatty acids (PUFA) decreased, while monounsaturated fatty acid (MUFA) content increased. Progression of oxidation was followed by measuring peroxide value (PV), p-anisidine (PAV), conjugated dienes (CD) and conjugated trienes (CT). Results: Inverse relationships were noted between PV and OS at termination of storage. Levels of CD and CT in SBO, and blends, increased with increase in time. The impact of SEO as additives on SBO oxidation was the strongest followed by RBO, CAO, SEBO and PNO. Conclusions: Oxidative stability of oil blends was better than SBO, most likely as a consequence of changes in fatty acids and tocopherols' profile, and minor bioactive lipids found in selected oils. The results suggest that these oil blends could contribute as sources of important antioxidant related to the prevention of chronic diseases associated to oxidative stress, such as in cancer and coronary artery disease.

Inhibition of microRNA-214 promotes epithelial mesenchymal transition process and induces interstitial cystitis in postmenopausal women by upregulating Mfn2

Jian-Wei Lv,Wei Wen,Chen Jiang,Qi-Bo Fu,Yin-Jun Gu,Ting-Ting Lv,Zhen-Dong Li,Wei Xue 생화학분자생물학회 2017 Experimental and molecular medicine Vol.49 No.-

Our study aims to investigate the roles that microRNA-214 (miR-214) plays in the epithelial mesenchymal transition (EMT) process and the development of interstitial cystitis (IC) in postmenopausal women by targeting Mitofusin 2 (Mfn2). IC bladder tissues and adjacent normal bladder tissues were collected from postmenopausal women. Immunohistochemistry (IHC) staining was conducted. The target relationship between miR-214 and Mfn2 was determined by a dual luciferase reporter gene assay. Adipose-derived mesenchymal stem cells (ADMSCs) were extracted from postmenopausal rats and assigned to the blank, mimics, miR-214 inhibitors, mimics negative control (NC), inhibitors NC, Mfn2 siRNA, miR-214 inhibitors and Mfn2 siRNA groups. Exosomes secreted by transfected ADMSCs were instilled into the bladders of postmenopausal rats. The expression of miR-214 and Mfn2 mRNA and EMT markers was assessed by qRT-PCR and western blotting. It was confirmed that Mfn2 was the target gene of miR-214 in IC. Compared with the normal bladder tissues, miR-214 decreased, but Mfn2 increased in IC bladder tissues. Compared with the blank group, the expression of miR-214 and the expression levels of N-cadherin, Fibronectin, Twist1, Snail and Vimentin mRNA and protein increased, whereas the expression levels of Mfn2, E-cadherin and ZO-1 mRNA and protein decreased in the miR-214 mimics and Mfn2 groups. The expression of MiR-214 and the expression levels of N-cadherin, Fibronectin, Twist1, Snail and Vimentin mRNA and protein decreased, whereas the expression levels of Mfn2, E-cadherin and ZO-1 mRNA and protein increased in the miR-214 inhibitors group. Our findings indicate that the inhibition of miR-214 promotes the EMT process and contributes to bladder wall fibrosis by up-regulating Mfn2, thus leading to the occurrence of IC in postmenopausal women.
