저자들은 하지 자색반과 고환 통증으로 내원한 알코올성 간경화증 환자에서 LCV의 원인 감별하는 과정에서 HCC와 하대정맥 막성폐쇄를 진단하고 이에 대한 치료 후 LCV의 호전된 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다. Vasculitis is a heterogeneous group of diseases that destroy blood vessel walls by inflammation. Approximately half of vasculitis cases are idiopathic, but sometimes associated with genetic factors, medicines, chronic infection, autoimmune diseases, and malignancies. Although the mechanism remains unclear, vasculitis secondary to malignancy, also known as paraneoplastic vasculitis, has been reported. It is generally associated with hematologic malignancies rather than solid malignancies and commonly presents as leukocytoclastic vasculitis or polyarteritis nodosa. We experienced a case of leukocytoclastic vasculitis in a patient with hepatocellular carcinoma and membranous obstruction of the inferior vena cava. Here, we report this case with a brief review of literature. (J Rheum Dis 2015;22:322-326)

The rainwater samples were collected from the 1100 Site of hlt. Halla and Cheju city during the period of March in 1997 to August in 1998. and the major soluble ions were analyzed. The confidence of analytical data was confirmed by using the comparison methods such as ion-balance, electric conductivity and acid fraction. all of which correlation coefficients were above 0.94. The ionic strengths lower than 10^(-4)M, the basis for the pure rainwater, were found in 47% and 38% at 1100 Site and Cheju city, respectively. The precipitations in Cheju city were more influenced by the oceanic effect than those in 1100 Site. The acidity contribution was mainly by SO_(4)^(2-) and NO_(3)^(-) in both areas. and the organic acids have contributed to the acidity with only 5-7%. The neutralization factors by NH_(3) were about 46% at both 1100 site and Cheju city, whereas those by CaCO_(3) were 11% and 15% at 1100 site and Cheju city respectively, and the free acidity were both about 35% in average. From the MSA analysis. it was found that the air in Cheju island has been influenced by the pollution from the other areas. The sources of the rainwater components in 1100 Site and Cheju city were also studied with a factor analyzing way and the most probable factors were found to be anthropogenic, oceanic, and soil-sourced. The results of multiple regression analysis have shown that SO_(4)^(??) was dissolved mostly in the form of H_(2)SO_(4), CaSO_(4) and (NH_(4))_(2)SO_(4). and NO_(3)^(-) was in the form of HNO_(3), Ca(NO_(3))_(2) and NH_(4)NO_(3).

<P>Although the overall risk of venous thromboembolism (VTE) is high in patients with non-small cell lung cancer (NSCLC), risk identification is limited. The goal of this study was to estimate the incidence, risk factors and prognostic implications of VTE, and to evaluate a genetic link between oncogenes and the risk of VTE in Asian patients with NSCLC. A total of 1,998 consecutive patients with NSCLC were enrolled and analysed retrospectively. Since the effects of therapeutics on VTE development were modified by stage, stratified analyses were performed. When comparing overall survival in terms of VTE development, a propensity score-matching method was adopted to minimise potential confounding. The six-month and two-year cumulative incidences of VTE were 4.2% and 6.4%, respectively. The risk of VTE increased 2.45-fold with each advancing stage in NSCLC (p<0.001). The independent predictors of VTE were advanced age, pneumonectomy and palliative radiotherapy in localised NSCLC and ineligibility for surgery and palliative radiotherapy in locally advanced NSCLC. Adenocarcinoma histology (vs squamous cell) and former/current smoking status were significant predictors of VTE in metastatic NSCLC. A significant association between VTE and decreased survival was observed only among patients with localised NSCLC. EGFR mutations (p=0.170) and ALK rearrangements (p=0.159) were not associated with VTE development in lung adenocarcinoma. In conclusion, the two-year cumulative incidence of VTE is 6.4% in Asian patient with NSCLC. The significant predictors of VTE are different across stages of NSCLC. The prognostic impact of VTE on poor survival was limited to localised NSCLC.</P>

<B>Background and Objective</B><P>Only a few surgeons with much experience of laparoscopic surgery perform laparoscopy-assisted total gastrectomy (LATG), because of its technical difficulty and concern about subsequent complications. The aim of this study was to evaluate the technical feasibility and safety of LATG as compared with laparoscopy-assisted distal gastrectomy (LADG) in gastric cancer.</P><B>Methods</B><P>From January 2002 to December 2007, LADG was performed in 473 patients and LATG in 67 patients at the Korean National Cancer Center. Surgical procedures and short-term surgical outcomes of LATG were analyzed.</P><B>Results</B><P>D2 lymph node dissection was performed in 35 LATG (52.2%) cases and in 274 LADG (57.9%) cases (P = 0.378). Mean blood losses during operation were 156.8 ± 158.0 ml and 190.7 ± 176.2 ml, respectively (P = 0.114). The open conversion rate for LATG was higher than LADG without significance (4.3% vs. 1.7%, P = 0.153). Complications occurred in 18 LATG cases (26.9%) and 38 LADG cases (8.0%) (P < 0.001). The most common postoperative complication of LATG was anastomotic stricture after esophagojejunostomy.</P><B>Conclusions</B><P>LATG is a technically feasible procedure as compared with LADG. However, its postoperative complication rate is higher than that of LADG, especially that of anastomotic stricture. A more effective anastomotic method during LATG is required to prevent stricture.

<P>The effects of Sn-deficiency on the thermoelectric properties of polycrystalline Sni(1-x)Se (x = 0, 0.01, 0.02, and 0.04) compounds were investigated. The Sn-deficiency caused the formation of the SnSe2 secondary phase in the compounds, and the charge and thermal transport properties were affected significantly by the secondary phase. Although the Sn-deficient compounds exhibited higher thermal conductivities than stoichiometric compound due to its high thermal conductivity of SnSe2, significantly improved power factors led to the enhancement of ZT. The highest ZT of 0.61 at 848 K was achieved in Sn0.98Se compound, and detailed effects of SnSe2 on the enhancement were discussed. (C) 2017 Elsevier B.V. All rights reserved.</P>

Background: This study was to investigate the effect of biomechanical stimulation on osteoblast differentiation of human periosteal-derived stem cell using the newly developed bioreactor. Methods: Human periosteal-derived stem cells were harvested from the mandible during the extraction of an impacted third molar. Using the new bioreactor, 4% cyclic equibiaxial tension force (0.5 Hz) was applied for 2 and 8 h on the stem cells and cultured for 3, 7, and 14 days on the osteogenic medium. Biochemical changes of the osteoblasts after the biomechanical stimulation were investigated. No treatment group was referred to as control group. Results: Alkaline phosphatase (ALP) activity and ALP messenger RNA (mRNA) expression level were higher in the strain group than those in the control group. The osteocalcin and osteonectin mRNA expressions were higher in the strain group compared to those in the control group on days 7 and 14. The vascular endothelial growth factor (VEGF) mRNA expression was higher in the strain group in comparison to that in the control group. Concentration of alizarin red S corresponding to calcium content was higher in the strain group than in the control group. Conclusions: The study suggests that cyclic tension force could influence the osteoblast differentiation of periosteal-derived stem cells under optimal stimulation condition and the force could be applicable for tissue engineering.
