We demonstrate a new technique of measuring differential carrier lifetime and linewidth enhancement factor in a semiconductor optical amplifier. In our method, the optical responses and fiber transfer functions of a self-gain modulated SOA are measured and, from these, values of carrier lifetimes and linewidth enhancement factors are determined for various SOA input optical powers.

Comments to young surgeons concerning laparoscopic spleenpreserving D2 lymph node dissection for advanced gastric cancer on the upper body

引用

Chinese Journal of Cancer Research 2014年第3期26卷 231-233页

作者： Yoon Young choi Ji Yeong An woo Jin Hyung Sung Hoon Noh Department of Surgery Yonsei University Health System Yonsei University College of Medicine

Qualified radical gastrectomy with lymph node dissection is very important to the prognosis of patients with gastric cancer. Now D2 lymph node dissection is standard procedure for gastric cancer surgery, and spleen hilar lymph node dissection is mandatory for gastric cancer in upper body. Because the anatomy of vessels in this area is very complicated, D2 lymph node dissection is technical challenging not only for open gastrectomy but also for laparoscopic one. Adapting a new technique is important to all surgeons, but we surgeons should always consider a patient＇s safety as the most important factor during surgery and that efforts should be based on scientific rationale with oncologic principles. I hope that the recent report by Huang et al. about laparoscopic spleen preserving hilar lymph node dissection would be helpful to young surgeons who will perform laparoscpic total gastrectomy for gastric cancer.

Potential risk factors for nonalcoholic steatohepatitis related to pancreatic secretions following pancreaticoduodenectomy

引用

World Journal of Gastroenterology 2011年第32期17卷 3716-3723页

作者： Sun Choon Song Seong Ho choi Dong wook choi Jin Seok Heo woo Seok Kim Min Jung Kim Department of Surgery Samsung Medical Center Sungkyunkwan University School of Medicine

AIM: To identify risk factors for nonalcoholic steatohepatitis following pancreaticoduodenectomy, with a focus on factors related to pancreatic secretions. METHODS: The medical records of 228 patients who had a pancreaticoduodenectomy over a 16-mo period were reviewed retrospectively. The 193 patients who did not have fatty liver disease preoperatively were included in the final analysis. Hepatic steatosis was diagnosed using the differences between splenic and hepatic attenuation and liver-to-spleen attenuation as measured by non-enhanced computed tomography. RESULTS: Fifteen patients (7.8%) who showed postoperative hepatic fatty changes were assigned to Group A, and the remaining patients were assigned to Group B. Patient demographics, preoperative laboratory findings (including levels of C-peptide, glucagon, insulin and glucose tolerance test results), operation types, and final pathological findings did not differ significantly between the two groups; however, the frequency of pancreatic fistula (P = 0.020) and the method of pancreatic duct stenting (P = 0.005) showed significant differences between the groups. A multivari- ate analysis identified pancreatic fistula (HR = 3.332, P = 0.037) and external pancreatic duct stenting (HR = 4.530, P = 0.017) as independent risk factors for the development of postoperative steatohepatitis. CONCLUSION: Pancreatic fistula and external pancreatic duct stenting were identified as independent risk factors for the development of steatohepatitis following pancreaticoduodenectomy.

Structural considerations in friction welding of hybrid Al_2O_3-reinforced aluminum composites

Comparative studies on the relationship between the welding parameters and joining efficiency in the friction welding of hybrid Al203-reinforced aluminum composites were conducted. Metal matrix composites （MMCs） with 37% （volume fraction） aluminum particle were joined by friction welding. The results show that the effects of the rotation speed on the reduction rate of particle size are greater than those of the upset pressure, and the area of the MMC weld zone decreases as the joining efficiency increases, while it is considered that the joining efficiency does not increase as the reduction rate of particle size decreases. During the macro-examination of the bonding interlace, a gray discolored region was observed on the bonding interface, and the center of the region was dark gray. After the micro-examination of the bonding interface, base metal made some second particulate formed by condensed alumina particulate but discoloration part distributed minute alumina particulate without second particulate. Consequently, it was also observed that rotational speed of 3 000 r/min and upset pressure of 63.6 MPa showed a very ***.

AIM： To confirm the predictive factors for interferon （IFN）-α and ribavirin combination therapy for chronic hepatitis patients with hepatitis C virus （HCV） genotype lb. METHODS： HCV RNA from 50 patients infected with HCV genotype lb was studied by cloning and sequencing of interferon sensitivity determining region （ISDR）, PKR- eIF2α phosphorylation homology domain （PePHD）. Patients were treated with IFN-α and ribavirin for 6 mo and grouped by effectiveness of the therapy. A variety of factors were analyzed. RESULTS： Our data showed that age, HCV RNA titer, and ISDR type could be used as the predictive factors for combined IFN-α and ribavirin efficacy. Characteristically, mutations in PePHD appeared only when the combination therapy was effective. Other factors, such as sex and alanine aminotransferase （ALT） level, were not related to its efficacy. Adjusting for age and HCV RNA titer indicated that the ISDR type was the most potent predictive factor. CONCLUSION： HCV RNA ISDR type is an important factor for predicting efficacy of IFN-α and ribavirin combination therapy in Korean patients.
