AIM:To investigate the predictive factors of selfexpandable metallic stent patency after stent placement in patients with inoperable malignant gastroduodenal obstruction. METHODS:A total of 116 patients underwent stent placements for inoperable malignant gastroduodenal obstruction at a tertiary academic center. Clinical success was defined as acceptable decompression of the obstructive lesion within the malignant gastroduodenal neoplasm. We evaluated patient comorbidities and clinical statuses using the World Health Organization's scoring system and categorized patient responses to chemotherapy using the Response Evaluation Criteria in Solid Tumors criteria. We analyzed the relationships between possible predictive factors and stent patency. RESULTS:Self-expandable metallic stent placement was technically successful in all patients(100%),and the clinical success rate was 84.2%. In a multivariate Cox proportional hazards model,carcinoembryonic antigen(CEA) levels were correlated with a reduction in stent patency [P = 0.006; adjusted hazard ratio(a HR)= 2.92,95%CI:1.36-6.25]. Palliative chemotherapy was statistically associated with an increase in stent patency(P = 0.009; a HR = 0.27,95%CI:0.10-0.72).CONCLUSION:CEA levels can easily be measured at the time of stent placement and may help clinicians to predict stent patency and determine the appropriate stent procedure.

Objective: To improve the detecting accuracy of chromosomal aneuploidy of fetus by non-invasive prenatal testing (NIPT) using next generation sequencing data of pregnant women’s cell-free DNA. Methods: We proposed the multi-Z method which uses 21 z-scores for each autosomal chromosome to detect aneuploidy of the chromosome, while the conventional NIPT method uses only one z-score. To do this, mapped read numbers of a certain chromosome were normalized by those of the other 21 chromosomes. Average and standard deviation (SD), which are used for calculating z-score of each sample, were obtained with normalized values between all autosomal chromosomes of control samples. In this way, multiple z-scores can be calculated for 21 autosomal chromosomes except oneself. Results: Multi-Z method showed 100% sensitivity and specificity for 187 samples sequenced to 3 M reads while the conventional NIPT method showed 95.1% specificity. Similarly, for 216 samples sequenced to 1 M reads, Multi-Z method showed 100% sensitivity and 95.6% specificity and the conventional NIPT method showed a result of 75.1% specificity. Conclusion: Multi-Z method showed higher accuracy and robust results than the conventional method even at low coverage reads.

研究植物源性发酵乳杆菌对免疫系统生理活性、抗高血糖和促进肠蠕动的影响。β-内啡肽对免疫系统有重要作用,阿片-促黑素细胞皮质素原(POMC)是β-内啡肽的前体物质,为了探讨发酵乳杆菌对免疫功能的影响,检测小鼠下丘脑和脑垂体中POMC的基因表达水平。通过喂食发酵乳杆菌时间和浓度的不同及测量β-内啡肽表达水平的方式,来分析血液中β-内啡肽的变化情况。此外,测定了三种小鼠模型的血糖变化,即常规的WT小鼠模型、D-葡萄糖诱导的急性高血糖模型和链唑霉素(STZ)诱导的糖尿病模型,以证实发酵乳杆菌的降血糖效果,并对降血糖效果进行了验证。通过检测血糖随喂食发酵乳杆菌浓度和时间而变化的情况,已证实给药浓度和时间对血糖浓度有很好的影响。另外,为证实发酵乳杆菌对肠蠕动的影响测定了胃肠通过时间,证明发酵乳杆菌对肠蠕动有极好的促进作用。通过此项研究,证实发酵乳杆菌对提高人体免疫系统的生理活性、抗高血糖和促进小肠蠕动有极佳的效果。

背景与目的非小细胞肺癌(non?small cell lung cancer, NSCLC)患者中非吸烟患者的比例正在增加,但在韩国,这个人数众多的群体并没有得到很好的治疗。本研究旨对NSCLC非吸烟患者的比例和临床特征进行一个单中心评估。方法我们分析了从2011年6月到2014年12月所有新诊断为NSCLC的1860例患者的临床数据。结果在1860例NSCLC患者中,707例(38%)从不吸烟。非吸烟患者中女性(83.7%vs.5.6%)和腺癌(89.8%vs. 44.9%)的比例均高于吸烟患者。非吸烟患者与吸烟患者相比,中位年龄明显更低(65 vs. 68岁,P<0.001),早期肿瘤比例更高(I–II期,44.5%vs. 38.9%,P=0.015)。与吸烟患者相比,表皮生长因子受体突变(57.8%vs. 24.4%,P<0.001)和间变性淋巴瘤激酶重排(7.8%vs. 2.8%,P<0.001)在非吸烟患者中更常见,而Kirsten大鼠肉瘤病毒癌基因同源染色体的基因突变(5.8%vs. 9.6%,P=0.021)出现频率则较低。在对年龄低、女性、腺癌、体能更好、疾病早期、诊断时无症状、曾接受抗肿瘤治疗以及存在驱动基因突变等的有利影响进行校正后,非吸烟患者的生存期比吸烟患者更长(hazard ratio,0.624,95%CI:0.460–0.848; P=0.003)。结论韩国超过三分之一的NSCLC患者是非吸烟者。NSCLC非吸烟患者与吸烟患者相比,有着不同的临床特征和主要驱动基因突变,总生存期更长。

Background: Because the cause and etiology of chronic headache is not yet fully explained, the treatment of this symptom is not simple. This study compares the effects of aroma acupuncture and normal acupuncture applied on chronic headache patients, in order to establish a primary data for further studies of new treatments and developments of new practical acupuncture. Methods: 38 clinical experiment participants were gathered and through a questionnaire patients who experienced headache for more than 4 hours a day and more than 15 days per month were qualified as chronic headache patients. The qualified patients were classified into two groups, aroma acupuncture group (Aroma AT group, n=23) and normal acupuncture group (AT group, n=15).

辣椒(Capsicum annuum)是美洲最古老的驯化作物之一,在全世界被广泛种植。本研究对CM334(墨西哥地方品种)进行了全基因组测序和组装(覆盖度为186.6×),同时还对另外两个栽培种和一个野生种分别进行了重测序和从头(de novo)测序。结果表明辣椒基因组大小约为番茄的4倍,辣椒基因组上存在大量gypsy转座子和花椰菜病毒家族元件的积累。结合转录组综合分析认为,辣椒素合成酶基因表达模式的改变及新功能化是导致辣椒素生物合成的原因,研究还发现辣椒与番茄在乙烯合成及果实成熟调控方面存在明显不同的分子模式。辣椒参考基因组的发布为辣椒营养品质和药用价值的改善提供了重要平台。
