胃出口梗阻是晚期胰腺、胃和十二指肠恶性肿瘤的一种晚期并发症。胃出口梗阻患者会出现难治性恶心、呕吐和厌食,进而可能导致电解质失衡、脱水和营养不良。此外,这些患者持续存在误吸和肺炎的风险。传统上,这些梗阻大多采用手术治疗。然而,许多患者由于初始评估时的身体状况不佳而不适合接受搭桥手术。此外,其发病率和死亡率显著较高,并与症状持续或延迟缓解和住院时间延长相关。球囊扩张术和金属支架置入已成功应用于不适合手术的患者。文章将对其适应证、禁忌证、技术、结果及争议进行综述。

Codium, one of the largest marine green algal genera, is difficult to delimit species boundary accurately based on morphological identification only. DNA barcoding is a powerful tool for discriminating species of seaweeds. The plastid elongation factor TU （tufA） is considered as maker to perform DNA barcoding of green algal species than rbcL gene due to universality and rapid evolution rate. We conducted DNA barcoding application to Codium specimens from the Jeju Island, Korea to overcome the limit of morphological identification and to confirm the species diversity. As a result of applying tufA marker, we newly generated fifty-five tufA barcodes to resolve eight species. TufA marker exhibited 6.1%–21.8% interspecific divergences, wider than the gap of rbcL exon 1, 3.5%–11.5%. Molecular analysis of rbcL exon 1 sequences of Codium revealed eight distinct species like tufA analysis separated in five phylogenetic groups. DNA barcoding of the genus Codium using tufA marker is more helpful to overcome the limit of morphological identification, and this is more potential to reveal cryptic species and to resolve the relationships among subspecies than rbcL analysis alone. The complement of tufA barcoding and rbcL analyses including morphology for the genus Codium in the northwestern Pacific will give much more reliable achievement for discovering species diversity and resolving the phylogenetic relationships.

Objective To evaluate the effect of 3-month kale （Brassica oleracea acephala） juice supplementation on coronary artery disease risk factors among hypercholesterolemic men. Methods Thirty-two men with hypercholesterolemia （〉 200 mg/dL） were recruited after annual health examinations among the faculty and staff at university. The subjects consumed 150 mL of kale juice per day for a 12-week intervention period. Dietary and anthropometric assessments were performed and blood samples were collected to evaluate biochemical profiles before and after supplementation. Results Serum concentrations of HDL-cholesterol, and HDL- to LDL-cholesterol ratio were significantly increased by 27% （P〈0.0001） and 52% （P〈0.0001）, respectively. The LDL-cholesterol concentration and the atherogenic index were significantly reduced by 10% （P=0.0007） and 24.2% （P〈0.0001）, respectively without affecting body mass index, waist and hip circumferences, or nutrient intakes after three months of supplementation. While there was no difference in the concentration of malondialdehyde, significant increase in glutathione peroxidase activity （P=0.0005） were accompanied by a significant increase in the serum selenium level （P=0.0132）. It was also found that the responses of these risk factors to kale juice administration were dependent on smoking status. Conclusion Regular meals supplementation with kale juice can favorably influence serum lipid profiles and antioxidant systems, and hence contribute to reduce the risks of coronary artery disease in male subjects with hyperlipidemia.
