Esophageal cancer is a highly lethal malignancy. Squamous cell cancer (SCC) and adenocarcinoma are two major histologic types of esophageal cancer. The therapeutic approaches for both histologic types tend to be similar. Endoscopic therapy is considered in patients with Tis and T1a, and surgery alone is recommended in patients with T1N0 esophageal SCC or adenocarcinoma. Definitive chemoradiotherapy is a reasonable option for patients unable to withstand surgery. Esophagectomy is considered as the initial treatment for patients with clinical T2N0 esophageal SCC and those with adenocarcinoma with low lymph node metastasis risk. Combined modality therapy is recommended for patients with T3N0, T4aN0, and clinically node-positive thoracic esophageal cancer, regardless of histology. Definitive concurrent chemoradiotherapy is the most appropriate treatment approach for patients with esophageal SCC who are not surgical candidates. Definitive concurrent chemoradiotherapy is also considered for esophageal SCC patients who are potential surgical candidates with an endoscopically documented complete response after neoadjuvant chemoradiotherapy. For chemoradiotherapy non-responders, surgery is recommended for those who remain operable after chemoradiotherapy. Esophagectomy is also recommended for patients with esophageal adenocarcinoma after neoadjuvant chemoradiotherapy. Definitive concurrent chemoradiotherapy is preferred over surgery in patients with cervical esophageal cancer because its survival rate is similar to that of surgery and major morbidity can be avoided. Concurrent chemoradiotherapy rather than radiation therapy alone is recommended for patients who can tolerate this approach for non-metastatic, inoperable, or unresectable esophageal SCC or adenocarcinoma.

사람성유아세포의 Transforming growth factor-$\beta$1과 Nitric oxide 생성에 미치는 Helicobacter pylori 항원의 효과
박무인,박선자,구자영,김광혁 한국생명과학회 2001 생명과학회지 Vol.11 No.2
Cytokines are hormone-like proteins which mediate and regulast inflammatory and immune responses. Transforming growth factor -$\beta$1(TGF-$\beta$) plays an important role in the control of the immune response and wound healing, and in the development o various tissues and organs, Nitric oxide(NO) is major messenger molecule regulating immune function and blood vessel dilation and serving as a neurotransmitter in the brain and peripheral nervous system. Also, NO is to be a potent mutagen that cause mutation in the p53 tumor suppressor gene in early phases of human gastric carcinogenesis. The purpose of this study was to investigate the effect of Helicobacter phlori lystes, lipopolysaccharide (LPS), and Staphylococcus enterotoxin B(SEB) on production of TGF-$\beta$1 and NO by human fibroblasts. Primary cultured human fibroblasts were incubated with H. pylori lysates(Hp), LPs, SEB, Hp+LPS, Hp+SEB, Hp+LPS+SEB. Cultured supernatants that were collected at 24, 48 and 72 hr were assessed for TGF-$\beta$1 by enzyme-linked immunosorbent assay and NO production by quantification of nitrite ion. TGF-$\beta$1 production in fibroblasts exposed with Hp, LPS or SEB for 48 hrs was enhanced, but for 72 hrs inhibited. Its production by doble exposure such as Hp+LPS, Hp+SEB, Hp+LPS+SEB was lowered in comparison with single exposure of Hp in cases of 24 and 48 hrs incubation, but for 72 hrs decreased in Hp vaculoating toxin(+), increased in Hp vacuolating toxin(-). No production in fibroblasts increaed at all doses of LPS. But its production by exposure of SEB increased or decreased according to dose and incubation time. Also, NO production by Hp vacuolating toxin(+) increased at all doses, but its production by Hp vacuolating toxin(-) decreased. Its production by doble exposure such as Hp+LPS, Hp+SEB, Hp+LPS+SEB decreased in comparison with single exposure Hp Therefore, quantities pf TGB-$\beta$1 and NO released by human fibroblasts shows differences according to kinds of stimulants. Also, in care stimulated with same kinds of stimulants, its productions exhibit quantitative differences according to exposure times. These results suggest that the decreased of TGF-$\beta$1 in fibroblasts by mixed exposure with Hp producing vacuolating toxin and bacterial toxins such as LPS and SEB may effect negatively in healing of host tissue and increased of NO by infection oh H. pylori may related to the increased susceptibility for human gastric carcinogenesis.
Can Dark Energy be a Bonus in Horava Gravity?
박무인 한국물리학회 2010 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.57 No.31
Recently, Hoˇrava proposed a renormalizable gravity theory with higher spatial derivatives in four dimensions which reduces to Einstein gravity with a non-vanishing cosmological constant in IR but with improved UV behaviors. Here, I consider a non-trivial test of the new gravity theory in a Friedmann-Robertson-Walker (FRW) universe by considering an IR modification which breaks “softly” the detailed balance condition in the original Hoˇrava model. I separate the dark energy parts from the usual Einstein gravity parts in the Friedman equations and obtain the formula of the equations of the state parameters. The IR-modified Hoˇrava gravity seems to be consistent with the current observational data, but we need some more refined data sets to see whether the theory is really consistent with our universe. From the consistency of our theory, I obtain some constraints on the allowed values of w0 and wa in Chevallier, Polarski, and Linder’s parametrization, and this may be tested in the near future, by sharpening the data sets.
