      • New Issues on Legal Sanction in Korea, China and Japan Position of Criminal Law in Risk Society

        ( Hong Jie Tian ) 아세아여성법학회 2013 아세아여성법학 Vol.16 No.-

        Risk society is not only a cognitive theory at the cultural level, but also features on its reflection significance at the political level and its reconfiguration connotation at the institutional level. Thus, any interpretation or analysis made from any single aspect for the risk society is unavoidably unilateral and single-track. The features of the risk society are increasingly prominent in modem society, which indicates the insufficiencies of the central governance capacity of the State and the failure of rigid governance mode created by laws. Therefore, facing the challenges of the risk society, no matter the adjustments on the governance structure or the society and reforms on the governance mode of the State, are continuously in pursuit of rational limitation of powers of the State, scientific configuration of multi-governance mechanism and firm defending for position of restraint of criminal law, rather than reinforcement of the power of the State and active expansion of function of criminal law.

        基于朝鲜半岛地缘价值的中国外交政策应对

        田?杰(Tian, Hong-jie) 한국동북아학회 2019 한국동북아논총 Vol.24 No.4

        한반도는 동북아 지역에서 매우 중요한 지정학적 가치를 가지고 있는데 이는 시기에 따라 달리 나타난다. 20세기 초반부터 지금까지 한반도를 둘러싸고 일련의 격렬한 이익충돌, 이를테면 한국전쟁을 비롯한 열전과 냉전이 벌어졌다. 전반적으로 한반도의 지정학적 가치 변천은 긍정적인 것과 부정적인 것의 두 가지 방향으로 진행되고 있다. 한반도를 둘러싼 강대국 정치의 각축이 여전히 치열하고, "북핵 위기"가 동북아 지역의 평화와 안보를 심각하게 위협하고 있는 한편, 한반도의 지정학적 주제는 안보와 평화, 협력과 발전, 화해와 통일의 추세로 나아가고 있다. 중국과 한반도의 지정학적 이해관계가 복잡하게 얽혀 있는 상황에서 중국은 시대 변화 및 한반도 지정학적 가치의 전환에 따라 그에 상응한 시기적절한 정책 조율이 필요하다. For northeast Asia, the Korean peninsula highlights its geopolitical significance periodically, which has a very important geostrategic value. Especially since the beginning of the 20th century, it has become the focus of the contention among the neighboring powers. Fierce conflicts of interests exist around the Korean peninsula, including hot wars such as the Korean wars and cold wars. The geopolitical value of the Korean peninsula develops towards both positive and negative directions. The current political competition among great powers around the Korean peninsula is still very fierce, and the "Korean nuclear crisis" seriously threatens the peace and security process in northeast Asia. However, the geopolitical value of the Korean peninsula is undergoing a profound transformation. In particular, security and peace, cooperation and development, and reconciliation and reunification are becoming the general trend. The geopolitical interests of China and the Korean peninsula are interwoven, so it is imperative for China to make timely policy changes along with the corresponding shift of geopolitical value in the new trend.

        Comparison of multiaxial fatigue damage models under variable amplitude loading

        Hong Chen,De-Guang Shang,Yu-Jie Tian,Jian-Zhong Liu 대한기계학회 2012 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.26 No.11

        Based on the cycle counting method of Wang and Brown and on the linear accumulation damage rule of Miner, four multiaxial fatigue damage models without any weight factors proposed by Pan et al., Varvani-Farahani, Shang and Wang, and Shang et al. are used to compute fatigue damage. The procedure is evaluated using the low cycle fatigue experimental data of 7050-T7451 aluminum alloy and En15R steel under tension/torsion variable amplitude loading. The results reveal that the procedure is convenient for engineering design and application, and that the four multiaxial fatigue damage models provide good life estimates.

      • PKM2 Regulates Hepatocellular Carcinoma Cell Epithelial-mesenchymal Transition and Migration upon EGFR Activation

        Fan, Fang-Tian,Shen, Cun-Si,Tao, Li,Tian, Chao,Liu, Zhao-Guo,Zhu, Zhi-Jie,Liu, Yu-Ping,Pei, Chang-Song,Wu, Hong-Yan,Zhang, Lei,Wang, Ai-Yun,Zheng, Shi-Zhong,Huang, Shi-Le,Lu, Yin Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.5

        Pyruvate kinase isozyme type M2 (PKM2) was first found in hepatocellular carcinoma (HCC), and its expression has been thought to correlate with prognosis. A large number of studies have demonstrated that epithelial-mesenchymal transition (EMT) is a crucial event in hepatocellular carcinoma (HCC) and associated metastasis, resulting in enhanced malignancy of HCC. However, the roles of PKM2 in HCC EMT and metastasis remain largely unknown. The present study aimed to determine the effects of PKM2 in EGF-induced HCC EMT and elucidate the molecular mechanisms in vitro. Our results showed that EGF promoted EMT in HCC cell lines as evidenced by altered morphology, expression of EMT-associated markers, and enhanced invasion capacity. Furthermore, the present study also revealed that nuclear translocation of PKM2, which is regulated by the ERK pathway, regulated ${\beta}$-catenin-TCF/LEF-1 transcriptional activity and associated EMT in HCC cell lines. These discoveries provide evidence of novel roles of PKM2 in the progression of HCC and potential therapeutic target for advanced cases.

      • Clinical Utility of Haptoglobin in Combination with CEA, NSE and CYFRA21-1 for Diagnosis of Lung Cancer

        Wang, Bing,He, Yu-Jie,Tian, Ying-Xing,Yang, Rui-Ning,Zhu, Yue-Rong,Qiu, Hong Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.22

        Purpose: To investigate the clinical value in lung cancer of a combination of four serum tumor markers, haptoglobin (Hp), carcinoembryonic antigen (CEA), neuron specific enolase (NSE) as well as the cytokeratin 19 fragment (CYFRA21-1). Materials and Methods: Serum Hp (with immune-turbidimetric method), CEA, NSE, CYFRA21-1 (with chemiluminescence method) level were assessed in 193 patients with lung cancer, 87 patients with benign lung disease and 150 healthy controls. Differences of expression were compared among groups, and joint effects of these tumor markers for the diagnosis of lung cancer were analyzed. Results: Serum tumor marker levels in patients with lung cancer were obviously higher than those with benign lung disease and normal controls (p<0.01). The sensitivities of Hp, CEA, NSE and CYFRA21-1 were 43.5%, 40.9%, 23.3% and 41.5%, with specificities of 90.7%, 99.2%, 97.9% and 97.9%. Four tumor markers combined together could produce a positive detection rate of 85.0%, significantly higher than that of any single test. With squamous carcinomas, the positive detection rates with Hp and CYFRA21-1 were higher than that of other markers. In the adenocarcinoma case, the positive detection rate of CEA was higher than that of other markers. For small cell carcinomas, the positive detection rate of NSE was highest. The area under receiver operating characteristic curve ($AUC^{ROC}$) of Hp in squamous carcinoma (0.805) was higher than in adenocarcinoma (0.664) and small cell carcinoma (0.665). Conclusions: Hp can be used as a new serum tumor marker for lung cancer. Combination detection of Hp, CEA, NSE and CYFRA21-1 could significantly improve the sensitivity and specificity in diagnosis of lung cancer, and could be useful for pathological typing.

        Patterns of Lymph Node Recurrence after Radical Surgery Impacting on Survival of Patients with pT1-3N0M0 Thoracic Esophageal Squamous Cell Carcinoma

        Xiao-li Chen,,Tian-wu Chen,Zhi-jia Fang,Xiao-ming Zhang,Zhen-lin Li,Hang Li,Hong-jie Tang,Li Zhou,Dan Wang,Zishu Zhang 대한의학회 2014 Journal of Korean medical science Vol.29 No.2

        The aim of this study was to investigate how patterns of lymph nodes recurrence after radical surgery impact on survival of patients with pT1-3N0M0 thoracic esophageal squamous cell carcinoma. One hundred eighty consecutive patients with thoracic esophageal squamous cell carcinoma underwent radical surgery, and the tumors were staged as pT1-3N0M0 by postoperative pathology. Lymph nodes recurrence was detected with computed tomography 3-120 months after the treatment. The patterns of lymph nodes recurrence including stations, fields and locations of recurrent lymph nodes, and impacts on patterns of survival were statistically analyzed. There was a decreasing trend of overall survival with increasing stations or fields of postoperative lymph nodes involved (all P<0.05). Univariate analysis showed that stations or fields of lymph nodes recurrence, and abdominal or cervical lymph nodes involved were prognostic factors for survival(all P<0.05). Cox analyses revealed that the field was an independent factor (P<0.05, odds ratio=2.73). Lymph nodes involved occurred predominantly in cervix and upper mediastinum (P<0.05). In conclusion, patterns of lymph node recurrence especially the fields of lymph nodes involved are significant prognostic factors for survival of patients with pT1-3N0M0 thoracic esophageal squamous cell carcinoma.

        Therapeutic Effect of Ginsenoside Rd in Rats with TNBS-Induced Recurrent Ulcerative Colitis

        Xiao-Lai Yang,Yong-Jie Wu,Tian-Kang Guo,Yan-Hong Wang,Ming-Tang Gao,Hong Qin 대한약학회 2012 Archives of Pharmacal Research Vol.35 No.7

        Ulcerative colitis (UC) is characterized by oxidative and nitrosative stress and neutrophil infiltration. In the present study, we aimed to investigate the therapeutic effect of ginsenoside Rd (GRd) in rats with 2,4,6-trinitrobenzenesulfonic acid (TNBS)-induced recurrent UC. After UC was twice-induced by intracolonic injection of TNBS, rats were intragastrically administered different doses of GRd per day for 7 days. The colonic lesions and inflammation were evaluated both histologically and biochemically. Compared with the TNBS group, GRd treatment facilitated recovery of pathologic changes in the colon after induction of recurrent UC, as evidenced by a significant reduction of colonic weight/length ratio and macroscopic and microscopic damage scores (p < 0.01). The myeloperoxidase and inducible nitric oxide synthase activities with malonyldialdehyde and nitric oxide levels in colonic tissues were significantly decreased in the GRd group compared with those in the TNBS group (p < 0.01). GRd treatment was associated with remarkably increased superoxide dismutase and glutathione peroxidase activities. Results showed a valuable effect of GRd against TNBS-induced recurrent UC by inhibiting neutrophil infiltration and promoting the antioxidant capacity of the damaged colonic tissue.

      • Surgical Treatment for Early Esophageal Squamous Cell Carcinoma

        Chen, Shao-Bin,Weng, Hong-Rui,Wang, Geng,Yang, Jie-Sheng,Yang, Wei-Ping,Liu, Di-Tian,Chen, Yu-Ping,Zhang, Hao Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.6

        More studies are needed to clarify treatments and prognosis of early esophageal squamous cell carcinoma (ESCC). This retrospective study was designed to review the outcome of surgical treatment for early ESCC, evaluate the results of a left thoracotomy for selected patients with early ESCC, and identify factors affecting lymph node metastases and survival. The clinicopathological data of 228 patients with early ESCC who underwent transthoracic esophagectomy with lymphadenectomy without preoperative adjuvant treatment were reviewed. The ${\chi}^2$ test or Fisher's exact test were used to detect factors related to lymph node metastasis. Univariate and multivariate analyses were performed to identify prognostic factors. There were 152 males and 76 females with a median age of 55 years. Two hundred and eight patients underwent a left thoracotomy, and the remaining 20 patients with lymph nodes in the upper mediastinum more than 5 mm in short-axis diameter by computed tomography scan underwent a right thoracotomy. No lymph node metastasis was found in the 18 patients with carcinoma in situ, while lymph node metastases were detected in 1.6% (1/62) of patients with mucosal tumours and 18.2% (27/148) of patients with submucosal tumours. Only 7 patients showed upper mediastinal lymph node metastases in the follow-up. The 5- and 10-year overall survival rates were 81.4% and 70.1%, respectively. Only histologic grade (P<0.001) and pT category (P=0.001) significantly correlated with the presence of lymph node metastases. In multivariate analysis, only histologic grade (P=0.026) and pT category (P=0.008) were independent prognostic factors. A left thoracotomy is acceptable for selected patients with early ESCC. Histologic grade and pT category affected the presence of lymph node metastases and were independent prognostic factors for early ESCC.
