Hepatitis B virus infection:A favorable prognostic factor for intrahepatic cholangiocarcinoma after resection

World Journal of Gastroenterology 2011年第10期17卷 1292-1303页

作者： Hua-Bang Zhou Hui Wang Yu-Qiong li Shuang-Xi li Hao Wang Dong-Xun Zhou qian-qian Tu Qing Wang shan-shan Zou Meng-Chao Wu He-Ping Hu Departmentof Comprehensive Treatment II Eastern Hepatobiliary Surgery Hospital Second Military Medical University Shanghai 200433 China

AIM： To study the prognostic factors for intrahepatic cholangiocarcinoma （ICC） and evaluate the impact of chronic hepatitis B virus （HBV） infection on survival rate of ICC patients. METHODS： A total of 155 ICC patients who underwent macroscopic curative resections （R0 and R1） were enrolled in this retrospective study and divided into group A with HBV infection and group B without HBV infection according to their chronic HBV infection, represented by positive hepatitis B surface antigen （HBsAg） in serum or in liver tissue. Clinicopathological characteristics and survival rate of the patients were evaluated. RESULTS： All patients underwent anatomical resection. Their 1- and 3-year survival rates were 60.6% and 32.1%, respectively. Multivariate analyses revealed that HBV infection, hepatolithiasis, microscopic satellite lesion, and lymphatic metastasis were the independent prognostic factors for the survival rate of ICC patients. The median disease-free survival time of the patients was 5.0 too. The number of tumors, microscopic satellite lesion, and vascular invasion were the independent prognostic factors for the disease-free survival rate of the patients. The prognostic factors affecting the survival rate of ICC patients with HBV infection and those without HBV infection were not completely consistent. Alkaline phosphatase 〉 119 U/L, microscopic satellite lesion, vascular invasion, and lymphatic metastasis were the independent factors for the patients with HBV infection, while r-glutamyltransferase 〉 64 U/L, microscopic satellite lesion, and poor tumor differentiation were the independent factors for the patients without HBV infection. CONCLUSION： HBV infection is a valuable clinical factor for predicting tumor invasiveness and clinical outcome of ICC patients. ICC patients with HBV infection should be distinguished from those without HBV infection because they have different dinicopathological characteristics, prognostic factors and outcomes after surgical resectio

Gonioscopy and Ultrasound Biomicroscopy in the Detection of Angle Closure in Patients with Shallow Anterior Chamber

Chinese Medical Sciences Journal 2014年第4期29卷 204-207页

作者： shan-shan Cui Yan-hong Zou qian li li-na li Ning Zhang Xi-pu liu Department of Ophthalmology First Hospital of Tsinghua University Medical Center Tsinghua University Department of Ophthalmology Sekwa Eye Hospital

Objective To assess the agreement between gonioscopy and ultrasound biomicroscopy(UBM) in detecting angle closure in Chinese patients with shallow anterior chamber. Methods An observational comparative study of the two different examination methods was conducted. Patients with normal intraocular pressure and temporal peripheral anterior chamber depth less than a quarter of corneal thickness based on slit lamp examination were included in this study from December 2007 to May 2009 in the outpatient clinic of First Hospital of Tsinghua University. Gonioscopy was performed with a Goldman goniolens in dark room first and followed by full beam light and indentation. If the filtering trabecular meshwork was invisible or any peripheral anterior synechia was found, that quadrant of the angle was considered closed. UBM was first undertaken in a darkened room then repeated with normal room lighting. If iridotrabecular apposition was showed, that quadrant of the angle was considered closed. The status of angle closure of each quadrant with different methods was recorded. Results 85 eyes of 46 patients were included in this study. The agreement between gonioscopy and UBM was poor(κlight conditions in each quadrant. The accordance of agreement between gonioscopy and UBM was hardly affected by age or sex, while in dark condition, eyes with deeper anterior chamber(P=0.005) or plateau iris configuration tended to produce different results(P=0.075) in the 2 methods. Conclusion Gonioscopy and UBM are both indispensable methods for detecting angle closure, neither can completely replace the other.

发芽糙米作为一种全谷物,保留了完整的皮层和胚,集中了大部分营养素和功能性活性物质,但由于皮层纤维结构致密,蒸饭过程中阻碍了吸水速率、吸水量和淀粉糊化,与大米相比,其蒸煮性和食用品质较差,且难以同煮同熟,因此一直以来未被广大消费者接受。本文综述糙米发芽的生理代谢反应及发芽过程中营养成分、活性成分和食味品质的变化,总结发芽糙米胁迫富集γ-氨基丁酸(γ-aminobutyric acid,GABA)技术和发芽糙米的功能特性研究现状。糙米发芽过程中,多种生物活性物质在酶促反应下富集,尤其是特征成分GABA含量显著提升。多种逆境胁迫均可通过改变Ca^(2+)、H^(+)或底物水平促进GABA富集,一些预处理技术可进一步提升发芽糙米的食味品质。GABA与其他营养成分和活性成分发挥协同作用,赋予发芽糙米抗高血脂、抗高血糖、保护心脏、改善睡眠、抗炎和抗氧化等一系列功效与作用。
