Background The clinical significance of complete revascularization for ST segment elevation myocardial infarction （STEMI） pa- tients during admission is still debatable. Methods A total of 1406 STEMI patients from the Korean Myocardial Infarction Registry with multivessel diseases without cardiogenic shock who underwent primary percutaneous coronary intervention （PPCI） were analyzed. We used propensity score matching （PSM） to control differences of baseline characteristics between culprit only intervention （CP） and multivessel percutaneous coronary interventions （MP）, and between double vessel disease （DVD） and triple vessel disease （TVD）. The major adverse cardiac event （MACE） was analyzed for one year after discharge. Results TVD patients showed higher incidence of MACE （14.2% vs. 8.6%, P = 0.01）, any cause of revascularization （10.6% vs. 5.9%, P - 0.01）, and repeated PCI （9.5% vs. 5.7%, P = 0.02）, as compared to DVD patients during one year after discharge. MP reduced MACE effectively （7.3% vs. 13.8%, P = 0.03）, as compared to CP for one year, but all cause of death （1.6% vs. 3.2%, P= 0.38）, Ml （0.4% vs. 0.8%, P = 1.00）, and any cause ofrevascularization （5.3% vs. 9.7%, P = 0.09） were comparable in the two treatment groups. Conclusions STEMI patients with TVD showed higher rate of MACE, as compared to DVD MP performed during PPCI or ad hoc during admission for STEMI patients without cardiogenic shock showed lower rate of MACE in this large scaled database. Therefore, MP could be considered as an effective treatment option for STEMI patients without cardiogenic shock.

AIM:To elucidate the effects of dexamethasone on hypoxia-induced epithelial-to-mesenchymal transition(EMT) in colon ***:Human colon cancer HCT116 and HT29 cells were exposed to normoxic(21%) and hypoxic(1%) conditions. First,the effect of dexamethasone on cell viability was examined by MTT cell proliferation assay. In order to measure the expression levels of EMT markers(Snail,Slug,Twist,E-cadherin,and integrin αVβ6) and hypoxia-related genes [Hypoxia-inducible factor-1α(HIF-1α) and vascular endothelial growth factor(VEGF)] by dexamethasone,quantitative real-time polymerase chain reaction and western blot analysis were performed. Furthermore,the morphological changes of colon cancer cells and the expression pattern of E-cadherin by dexamethasone were detected through immunocytochemistry. Finally,the effects of dexamethasone on the invasiveness and migration of colon cancer cells were elucidated using matrigel invasion,migration,and wound healing migration ***:Under hypoxia,dexamethasone treatment inhibited HIF-1α protein level and its downstream gene,VEGF m RNA level in the colon cancer cell lines,HCT116 and HT29. In addition,the presence of dexamethasone down-regulated the m RNA levels of hypoxia-induced Snail,Slug,and Twist,all transcriptional factors of EMT,as well as hypoxia-induced integrin αVβ6 protein level,a well-known EMT marker for colon cancer cells. Furthermore,reduced E-cadherin in hypoxic condition was found to be recoverable by treating with dexamethasone in both colon cancer cell lines. Similarly,under hypoxic conditions,dexamethasone restored the growth pattern and morphological phenotype reminiscent of colon cancer cells grown under normoxic conditions; dexamethasone blocked the migration and invasion of both colorectal cancer cell lines in ***:Our study suggested that dexamethasone has inhibitory effects on cell migration and invasion by suppressing EMT of colon cancer cell lines in hypoxic condition.

We isolated various extracts from Hei Lao Hu, a well known traditional Chinese medicine, and found inhibitory effect on melanogenesis. Among them, an extract dose-dependently inhibited melanin synthesis in melan-a, mouse melanocytes. The extract showed more effectiveness than arbutin;melanin synthesis inhibitory activity treated with 2ppm of the extract was better than that with 50 ppm of arbutin. Using further high performance liquid chromatography(HPLC) analysis, we identified a novel compound, kadsuralignan F with strong melanin synthesis inhibition in melan-a cells(IC50=2.7ppm). Western blot analysis demonstrated that kadsuralignan F significantly reduced melanogenic proteins including tyrosinase, tyrosinase related protein(TRP)-1, and TRP-2. These results suggested Hei Lao Hu has potential as an effective skin whitening agent.

The quasioptical system of the dual channel receiver is designed and developed for the simultaneous observation with two bands. The frequency independent matching of Gaussian beam is applied to design the quasioptical system with two focusing elements for each band, respectively. The emphasis is on the design to be satisfied with two bands simultaneously. The beam measurement system is also developed to measure the quasioptical system and their components as well as to align the quasioptical elements. We have measured the intensity distributions of the Gaussian beam in the transverse plane and the variations of the beam widths along the propagation axis near the Cassegrain focus. The measured results are also compared the theory.
