| 1 | Dietary fat-associated osteoarthritic chondrocytes gain resistance to lipotoxicity through PKCK2/STAMP2/FSP27显示文摘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. | 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 | 2018 | Bone Research2018，6，3： | 3 |

| 3 | Inverse correlation between gastroesophageal reflux disease and atrophic gastritis assessed by endoscopy and serology显示文摘BACKGROUND Helicobacter pylori(H.pylori)infection is known to prevent the occurrence of gastroesophageal reflux disease(GERD)by inducing gastric mucosal atrophy.However,little is known about the relationship between atrophic gastritis(AG)and GERD.AIM To confirm the inverse correlation between AG and the occurrence and severity of GERD.METHODS Individuals receiving health checkups who underwent upper gastrointestinal endoscopy at Seoul National University Healthcare System Gangnam Center were included.The grade of reflux esophagitis was evaluated according to the Los Angeles classification.Endoscopic AG(EAG)was categorized into six grades.Serologic AG(SAG)was defined as pepsinogen I≤70 ng/m L and pepsinogen I/II ratio≤3.0.The association between the extent of EAG and SAG and the occurrence and severity of GERD was evaluated using multivariate logistic regression analysis.RESULTS In total,4684 individuals with GERD were compared with 21901 healthy controls.In multivariate logistic regression analysis,advanced age,male sex,body mass index>23 kg/m2,presence of metabolic syndrome,current smoking,and alcohol consumption were associated with an increased risk of GERD.Seropositivity for H.pylori immunoglobulin G antibodies was associated with a decreased risk of GERD.There was an inverse correlation between the extent of EAG and occurrence of GERD:Odds ratio(OR),1.01[95%confidence interval(CI):0.90-1.14]in C1,0.87(0.78-0.97)in C2,0.71(0.62-0.80)in C3,0.52(0.44-0.61)in O1,0.37(0.29-0.48)in O2,and 0.28(0.18-0.43)in O3.Additionally,the extent of EAG showed an inverse correlation with the severity of GERD.The presence of SAG was correlated with a reduced risk of GERD(OR=0.49,95%CI:0.28-0.87,P=0.014).CONCLUSION The extent of EAG and SAG exhibited strong inverse relationships with the occurrence and severity of GERD.AG followed by H.pylori infection may be independently protect against GERD. | Yoo Min Han Su Jin Chung Seokha Yoo Jong In Yang Ji Min Choi Jooyoung Lee Joo Sung Kim | 2022 | World Journal of Gastroenterology2022，28，8： | 3 |
| 4 | Pemetrexed in Previously Treated Non-small Cell Lung Cancer Patients with Poor Performance Status显示文摘Background and objective Pemetrexed have been approved for the treatment of patients affected by advanced non-small cell lung cancner(NSCLC) in progression after first-line chemotherapy.We evaluated the activity and feasibility of pemetrexed in previously treated NSCLC.Methods Patients with histologically or cytologically confirmed NSCLC were evaluated from April 2007 to March 2009.The patients had relapsed or progressed after prior chemotherapy treatment.Pemetrexed(500 mg/m2) was administered intravenously once every 3 weeks after progression to prior chemotherapy.The tumor response was evaluated according to RECIST criteria by chest CT at every 2 cycles of chemotherapy.Results A total 61 patients were eligible for analysis.Performance status of them(100%) was over 2.The response rate and disease control rate were 14.7% and 37.7% respectively.Non-squamous cell carcinoma histology was significantly associated with a superior response rate(P=0.045) and disease control rate(P=0.008).The median survival time and the median progression free survival(PFS) time were 6.11 months and 2.17 months,respectively.Comparing the efficacy of pemetrexed in these two settings [second-line versus(12/61) more than third(49/61)],there was no significant difference in regard to median survival(11.18 months vs 11.46 months,P=0.922,5),but PFS was more longer in third-or further-line groups than second-line group(1.39 months vs 2.25 months,P=0.015,3).Conclusion Pemetrexed is a feasible regimen in previously treated NSCLC with poor performance status. | Sun Young JUNG Su Jin YOO Ji Young SHIN Ji Won PARK Jeong Eun LEE Hee Sun PARK Ju Ock KIM Sun Young KIM | 2011 | 中国肺癌杂志2011，14，1： | 3 |
| 5 | Prognostic value of 18-fluorodeoxyglucose positron emission tomography-computed tomography in resectable colorectal cancer显示文摘AIM:To assess the prognostic value of preoperative 18 fluorodeoxyglucose positron emission tomography(FDG-PET)/computed tomography(CT) in patients with resectable colorectal cancer.METHODS:One hundred sixty-three patients with resectable colorectal cancer who underwent FDG-PET/CT before surgery were included.Patient data including pathologic stage at presentation,histology,treatment,disease-free survival and the maximum standardized uptake value(SUVmax) of the primary tumor on FDG-PET/CT were retrospectively analyzed.Median follow up duration was 756(range,419-1355).The primary end point was disease-free survival.RESULTS:Twenty-five of 163 patients(15.3%) had recurrences.The median SUVmax values of the recurrence and no-recurrence groups were 8.9(range,5-24) and 8.2(range,0-23,P = 0.998).Receiver operating characteristic(ROC) curve analysis showed no significant association between SUVmax and recurrence(area under the curve = 0.5,P = 0.998,95% CI:0.389-0.611).Because a statistically significant value was not found,SUVmax was dichotomized at its median of 8.6.The disease-free survival curve was analyzed using the median SUVmax(8.6) as the cut off.Univariate and multivariate analysis did not provide evidence that disease-free survival rates for the subgroups defined by the median SUVmax were significantly different(P = 0.52,P = 0.25).CONCLUSION:Our study suggests that the high FDG uptake of primary mass in resectable colorectal cancer doesn't have a significant relationship with tumor recurrence and disease-free survival. | Jang Eun Lee Sang Woo Kim Jin Su Kim Kyu Yong Choi Won Kyung Kang Seong Taek Oh Ie Ryung Yoo Sung Hoon Kim | 2012 | World Journal of Gastroenterology2012，18，36： | 3 |
