BACKGROUND Noninvasive ventilation(NIV)reduces intubation rates,mortalities,and lengths of hospital and intensive care unit stays in patients with acute exacerbation of chronic obstructive pulmonary disease(AECOPD).Helmet-based NIV is better tolerated than oronasal mask-based ventilation,and thus,allows NIV to be conducted for prolonged periods at higher pressures with minimal air *** SUMMARY A 73-year-old man with a previous diagnosis of COPD stage 4 was admitted to our medical intensive care unit with chief complaints of cough,sputum,and dyspnea of several days’*** 10 mo,he had been on oxygen at home by day and had used an oronasal mask-based NIV at *** intensive care unit admission,he breathed using respiratory accessory *** and signs of infection were detected,and infiltration was observed in the right lower lung field by chest ***,we diagnosed AECOPD by communityacquired *** admission,respiratory distress steadily deteriorated and invasive mechanical ventilation became ***,the patient refused this option,and thus,we selected helmet-based NIV as a salvage *** 3 d of helmet-based NIV,his consciousness level and hypercapnia recovered to his pre-hospitalization *** Helmet-based NIV could be considered as a salvage treatment when AECOPD patients refuse invasive mechanical ventilation and oronasal mask-based NIV is ineffective.

Comparison of RECIST version 1.0 and 1.1 in assessment of tumor response by computed tomography in advanced gastric cancer

引用

Chinese Journal of Cancer Research 2013年第6期25卷 689-694页

作者： Gil-Su Jang min-jeong kim Hong-Il Ha Jung Han kim Hyeong Su kim Sung Bae Ju Dae Young Zang Department of Internal Medicine Hallym University Sacred Heart Hospital Department of Diagnostic Radiology Hallym University Sacred Heart Hospital Department of Internal Medicine Kangnam Sacred Heart Hospital

Objective： Response Evaluation Criteria in Solid Tumors （RECIST） guideline version 1.0 （RECIST 1.0） was proposed as a new guideline for evaluating tumor response and has been widely accepted as a standardized measure. With a number of issues being raised on RECIST 1.0, however, a revised RECIST guideline version 1.1 （RECIST 1.1） was proposed by the RECIST Working Group in 2009. This study was conducted to compare CT tumor response based on RECIST 1.1 vs. RECIST 1.0 in patients with advanced gastric cancer （AGC）. Methods： We reviewed 61 AGC patients with measurable diseases by RECIST 1.0 who were enrolled in other clinical trials between 2008 and 2010. These patients were retrospectively re-analyzed to determine the concordance between the two response criteria using the κ statistic. Results： The number and sum of tumor diameters of the target lesions by RECIST 1.1 were significantly lower than those by RECIST 1.0 （P〈0.0001）. However, there was excellent agreement in tumor response between RECIST 1.1 and RECIST 1.0 0（κ=0.844）. The overall response rates （ORRs） according to RECIST 1.0 and RECIST 1.1 were 32.7% （20/61） and 34.5% （20/58）, respectively. One patient with partial response （PR） based on RECIST 1.0 was reclassified as stable disease （SD） by RECIST 1.1. Of two patients with SD by RECIST 1.0, one was downgraded to progressive disease and the other was upgraded to PR by RECIST 1.1. Conclusions： RECIST 1.1 provided almost perfect agreement with RECIST 1.0 in the CT assessment of tumor response of AGC.

AIM:To investigate serotonergic Ca 2+ signaling and the expression of 5-hydroxytryptamine(5-HT) receptors,as well as Ca 2+ transporting proteins,in hepatic stellate cells(HSCs) . METHODS:The intracellular Ca 2+ concentration([Ca 2+ ]i) of isolated rat HSCs was measured with a fluorescence microscopic imaging *** PCR was per-formed to determine the transcriptional levels of 5-HT receptors and endoplasmic reticulum(ER) proteins involved in Ca 2+ storage and release in cultured rat HSCs. RESULTS:Distinct from quiescent cells,activated HSCs exhibited[Ca 2+ ]i transients following treatment with 5-HT,which was abolished by U-73122,a phospholipase C *** of 5-HT2A and 5-HT2B receptors,but not 5-HT3,was prominent during trans-differentiation of *** with ritanserin,a 5-HT2 antagonist,inhibited[Ca 2+ ]i changes upon application of *** of type 1 inositol-5'-triphosphate receptor and type 2 sarcoplasmic/endoplasmic reticulum Ca 2+ ATPase were also increased during activation of HSCs and serve as the major isotypes for ER Ca 2+ storage and release in activated *** 2+ binding chaperone proteins of the ER,including calreticulin,calnexin and calsequestrin,were up-regulated following activation of HSCs. CONCLUSION:The appearance of 5-HT-induced[Ca 2+ ]i response accompanied by upregulation of metabotropic 5-HT2 receptors and Ca 2+ transporting/chaperone ER proteins may participate in the activating process of HSCs.

Tensile creep and corrosion properties of Mg-2%Ca based cast alloys

引用

Transactions of Nonferrous Metals Society of China 2011年第4期21卷 869-873页

作者： jeong-min kim Joon-Sik PARK Ki-Tae kim Division of Advanced Materials Engineering Hanbat National University Incheon R&D Center Korea Institute of Industrial Technology

The relative effect of Zn addition to Mg-2%Ca based alloy on the creep and corrosion characteristics was compared with Al addition. The creep resistance of Mg-2%Ca based alloy at 175 ℃was improved by Zn addition more significantly than by Al addition. However, the Al addition showed more effective in enhancing corrosion resistance. Since the solidification range for Zn-added alloy was considerably wide, the cautious casting design may be necessary to produce high-quality castings.

Oxidation resistance of Si-coated TZM alloy prepared through combined process of plasma spray and laser surface melting

引用

Transactions of Nonferrous Metals Society of China 2016年第10期26卷 2603-2608页

作者： jeong-min kim Tae-Hyung HA Joon-Sik PARK Hyun-Gil kim Department of Advanced Materials Engineering Hanbat National UniversityDaejeon 34158Korea Korea Atomic Energy Research Institute Daejeon 34057Korea

Plasma thermal spraying ofSi coating layer ontitanium-zirconium-molybdenum （Ti-Zr-Mo）,TZM alloy,was conducted for the surface protection of the Mo substrate that is unstable in air at high temperatures. Although the plasma thermal spraying alone could protect the Mo alloy from oxidation at a high temperature for a short time, the post laser surface melting process further improved the oxidation resistance of Si-coated alloy. In the case of the post laser treated specimen,MoSi compounds, mainly MoSi2 phases, were formed during the additional annealing process, and the oxidation resistance could be even further enhanced. The corrosion behaviors of Si-coated specimens in 3.5%NaCl solution were also investigated;however,nosignificant variations with respect to the post treatment procedure were found.
