Family history influences the early onset of hepatocellular carcinoma

World Journal of Gastroenterology 2012年第21期18卷 2661-2667页

作者： chung-Hwa Park Seung-Hee Jeong Hyeon-Woo Yim jin Dong Kim Si Hyun Bae Jong young Choi Seung Kew Yoon Department of Internal Medicine The Catholic University of KoreaSeoul 137-701 South Korea Department of Preventive Medicine College of Medicine The Catholic University of KoreaSeoul 137-701 South Korea Clinical Research Coordinating Center of Catholic Medical Center The Catholic University of KoreaSeoul 137-701 South Korea

AIM: To evaluate the relationship between a positive family history of primary liver cancer and hepatocellular carcinoma (HCC) development in Korean HCC patients. METHODS: We studied a total of 2242 patients diagnosed with HCC between January 1990 and July 2008, whose family history of primary liver cancer was clearly described in the medical *** family history of HCC and 2077 (92.6%) did not. The male to female ratio was 3.6:1, and the major causes of HCC were chronic hepatitis B virus (HBV) infection in 75.1%, chronic hepatitis C virus infection in 13.2% and alcohol in 3.1%. The median ages at diag- nosis in the positiveand negative-history groups were 52 years (range: 29-79 years) and 57 years (range: 18-89 years), respectively (P < 0.0001). Furthermore, among 1713 HCC patients with HBV infection, the number of patients under 45 years of age out of 136 patients with positive family history was 26 (19.1%), whereas those out of 1577 patients with negative family history was 197 (12.5%), suggesting that a positive family history may be associated with earlier development of HCC in the Korean population (P = 0.0028). CONCLUSION: More intensive surveillance maybe recommended to those with a positive family history of HCC for earlier diagnosis and proper management especially when HBV infection is present.

International Journal of Ophthalmology(English edition) 2018年第3期11卷 462-469页

作者： Dong Hui Lim Eui-Sang chung Myoung Joon Kim Tae-young chung Department of Ophthalmology Samsung Medical Center Sungkyunkwan University School of Medicine Department of Preventive Medicine Graduate School the Catholic University of Korea Department of Ophthalmology University of Ulsan College of MedicineAsan Medical Center

AIM： To assess visual quality after presbyopia correction using an aspheric ablation profile and a micro-monovision protocol. METHODS： This is a retrospective interventional study. Fifty-four eyes of 27 patients （mean age, 50.2±7.5y） who underwent presbyopia correction with an aspheric micro-monovision protocol were enrolled. The values of modulation transfer function （MTF） cutoff frequency, Strehl ratio, objective scattering index （OSI） and accommodation range were quantitatively assessed using the HD analyzer. Preoperative and postoperative contrast sensitivity （CS） at far （2.5 m） and near （40 cm） distance and higher-order aberrations （HOAs） were analyzed. Subjective visual satisfaction was evaluated by self-reported questionnaire regarding optical visual symptoms. RESULTS： One year after presbyopia correction, no significant differences were found in the MTF cutoff frequency, Strehl ratio and OSI, however, the lID analyzer accommodation range significantly differed postoperatively （P=0.004）. Postoperative CS at 12 and 18 cpd at near showed statistically significant improvement （P=0.020 and 0.008, respectively）. Visual performance by self-reported questionnaire revealed satisfactory results in terms of subjective visual quality improvement. CONCLUSION： Objective optical quality parameters show good visual outcomes. Subjective visual quality assessed by self-reported questionnaire in the presbyopia correction group show satisfactory results.

Dietary fat-associated osteoarthritic chondrocytes gain resistance to lipotoxicity through PKCK2/STAMP2/FSP27

引用

Bone Research 2018年第3期6卷 238-251页

作者： Sung Won Lee Jee Hyun Rho Sang Yeob Lee Won Tae chung Yoo jin Oh Jung Ha Kim Seung Hee Yoo Woo young Kwon Ju Yong Bae Su young Seo Hokeun Sun Hye young Kim young Hyun Yoo Department of Rheumatology Dong-A University College of Medicine Department of Anatomy and Cell Biology Dong-A University College of Medicine and Mitochondria Hub Regulation Center Department of Microbiology Dong-A University College of Medicine Department of Statistics Pusan National University

Free fatty acids(FFAs), which are elevated with metabolic syndrome, are considered the principal offender exerting lipotoxicity. Few previous studies have reported a causal relationship between FFAs and osteoarthritis pathogenesis. However, the molecular mechanism by which FFAs exert lipotoxicity and induce osteoarthritis remains largely unknown. We here observed that oleate at the usual clinical range does not exert lipotoxicity while oleate at high pathological ranges exerted lipotoxicity through apoptosis in articular chondrocytes. By investigating the differential effect of oleate at toxic and nontoxic concentrations, we revealed that lipid droplet(LD) accumulation confers articular chondrocytes, the resistance to lipotoxicity. Using high fat diet-induced osteoarthritis models and articular chondrocytes treated with oleate alone or oleate plus palmitate, we demonstrated that articular chondrocytes gain resistance to lipotoxicity through protein kinase casein kinase 2(PKCK2)—six-transmembrane protein of prostate 2(STAMP2)—and fat-specific protein 27(FSP27)-mediated LD accumulation. We further observed that the exertion of FFAs-induced lipotoxicity was correlated with the increased concentration of cellular FFAs freed from LDs, whether FFAs are saturated or not. In conclusion, PKCK2/STAMP2/FSP27-mediated sequestration of FFAs in LD rescues osteoarthritic chondrocytes. PKCK2/STAMP2/FSP27 should be considered for interventions against metabolic OA.

AIM: To explore the expression pattern of E2F5 in primary hepatocellular carcinomas (HCCs) and elucidate the roles of E2F5 in hepatocarcinogenesis. METHODS: E2F5 expression was analyzed in 120 primary HCCs and 29 normal liver tissues by immunohistochemistry analysis. E2F5-small interfering RNA was transfected into HepG2, an E2F5-overexpressed HCC cell line. After E2F5 knockdown, cell growth capacity and migrating potential were examined. RESULTS: E2F5 was significantly overexpressed in primary HCCs compared with normal liver tissues (P = 0.008). The E2F5-silenced cells showed significantly reduced proliferation (P = 0.004). On the colony formation and soft agar assays, the number of colonies was significantly reduced in E2F5-silenced cells (P = 0.004 and P = 0.009, respectively). E2F5 knockdown resulted in the accumulation of G0/G1 phase cells and a reduction of S phase cells. The number of migrating/invading cells was also reduced after E2F5 knockdown (P = 0.021). CONCLUSION: To our knowledge, this is the first evidence that E2F5 is commonly overexpressed in primary HCC and that E2F5 knockdown significantly repressed the growth of HCC cells.

Moving Personal-Cell Network: Characteristics and Performance Evaluation

Recent years have witnessed a huge demand for ubiquitous communications services from continuously moving users. In order to provide seamless network services to high-mobility users, one of the promising solution proposed by 3 GPP is the deployment of moving-relays. In this article, we introduce the concept of Moving-Personal-Cell(mPC), which is a type of moving-relays. mPC is a user-centric network, which aims to provide reliable network services to moving users. A mPC receives data-traffic from eNB and its neighboring mPCs via wireless backhaul and sidehual links respectively and forwards the received data to its serving users. In addition to this, mPC can also increase the network capacity by caching and distributing the popular contents to its serving users. Besides these pros, the mPC also has some limitations, as its performance is highly affected by cross-tier and co-tier interferences. In this article, we analyze the effect of these interferences on mPCs performance. Our results show that the performance of mPC network is equally affected by the capacity of wireless backhaul, sidehaul, and access links. Moreover, since mPCs accommodate data traffic from wireless backhaul, sidehaul links, and content cache, their performance is also affected by the ratio of data-traffic delivered via these links.
