Metabonomic analysis of hepatitis B virus-induced liver failure： identification of potential diagnostic biomarkers by fuzzy support vector machine

Hepatitis B virus （HBV）-induced liver failure is an emergent liver disease leading to high mortality. The severity of liver failure may be reflected by the profile of some metabolites. This study assessed the potential of using metabolites as biomarkers for liver failure by identifying metabolites with good discriminative performance for its phenotype. The serum samples from 24 HBV-indueed liver failure patients and 23 healthy volunteers were collected and analyzed by gas chromatography-mass spectrometry （GC-MS） to generate metabolite profiles. The 24 patients were further grouped into two classes according to the severity of liver failure. Twenty-five eommensal peaks in all metabolite profiles were extracted, and the relative area values of these peaks were used as features for each sample. Three algorithms, F-test, k-nearest neighbor （KNN） and fuzzy support vector machine （FSVM） combined with exhaustive search （ES）, were employed to identify a subset of metabolites （biomarkers） that best predict liver failure. Based on the achieved experimental dataset, 93.62% predictive accuracy by 6 features was selected with FSVM-ES and three key metabolites, glyeerie acid, cis-aeonitie acid and citric acid, are identified as potential diagnostic biomarkers.

浅谈高校和谐教研室建设中团队精神的培养

教研室作为高等学校教学科研的最基本单位，是培养教师团队精神、构建和谐教学环境的根本。加强教师团队精神的培养，充分发挥教师团队协同作战的优势，把教研室和教师个人的发展融为一体，从而促进学校组织的全面、健康、持续发展已经成为现代教研室管理中一项不可缺少的内容。     

重正化群方法处理正方格子伊辛模型

分别通过正方格子伊辛模型的二格点集团、四格点集团及五格点集团的重正化变换群方法求解了二级相变临界温度．结果符合集团越大越准确这一规律，但同时也显示出一两个格点的增加对准确度的提高程度大致与确定集团自旋的不同方法之间的误差相当，所以要想明显提高准确度，应较大量地增加集团格点数．最后，指出了按一定法则计算时容易出错的地方。     

Morphological variability and genetic diversity in five species of Skeletonema （Bacillariophyta）

Twelve strains of Skeletonema from Chinese coastal waters and another strain from the West Sea of Korea were examined using light microscopy （LM）, scanning and transmission electron microscopy （SEM, TEM）, and small subunit （SSU） rDNA sequence analysis. We identified four species of Skeletonema： S. marinoi Sarno et Zingone, S. subsalsum （A.Cleve） Bethge, S. dohrnii Sarno et Kooistra, S. trop- icum Cleve, as well as a Skeletonerna-like species. These are the first records of S. rnarinoi, S. dohrnii and S. subsalsurn in China. The Skeletonema-like species, MMDLS067, was isolated from the estuary of the Changjiang River. The morphologic and phylogenetic characteristics of this species are not correspond to those of any previously published Skeletonerna species. The intercalary fultoportula pro- cesses （IFPPs） has long open tubes, and the intercalary rimoportula process （IRP） is short and located inside the rim of the IFPPs. Phylogenetic analysis revealed that MMDL5630 clustered with S. tropicurn in the NJ and MP trees, but its IRPs differed from those of previously described specimens of S. tropicum. The IRP is partially open, with an elongated opening at the base of the tube, and is longer than the IFPPs. Some specimens of S. marinoi and S. dohrnii also have longer tubular IRPs than the IFPPs. Compared to pre- viously described specimens of S. rnar＆oi and S. dohrnii, these two specimens we identified have shorter IRPs. Our results reflect the ambiguity and diversity of Skeletonema taxonomy. They are also significant for the future identification and management of red tides caused by Skeletonerna in the seas around China.     

苹果果实大小与膜透性、过氧化物酶活性及丙二醛含量关系的研究

本文分析了苹果果实后熟衰老期间膜透性、过氧化物酶活性及丙二醛含量。结果表明,苹果果实大小不影响其过氧化物酶活性高低,但大果具有较大的过氧化物酶活性变化幅度,中等果具有较低小的过氧化物酶变化幅度。大果比中等果具有较高的膜透性与丙二醛含量。
