The new synthesis of 10-bromo-α-chamigrene was achieved as follows; 6-methyl-5-heptene-2-one was transformed into corresponding thioacetals, and then successively treated with Cp2Ti（P（OEt）3）2. The intermediate reacted with mono-ketal of cyclohexane-1,4-dione, and gave the carbonyl coupling product. It was then transformed into the key intermediate γ-bisabolene via deketalization, Grignard reaction, dehydration and then furnished the target molecule by polyene cyclization, with total yield 2%. All structures were confirmed by ^1H NMR and ^13C NMR. The final compound was confirmed by ^1H NMR, ^13C NMR and MS.

Objective To obtain the full-length cDNA of a novel gene （named yp05） associated with citrinin production-related genes in Monascus aurantiacus. Methods Total RNA was extracted from mycelium, 3＇ and 5＇ cDNA end of yp05 gene was amplified using smartTM trace cDNA amplification kit, and the full-length cDNA of a novel gene （named yp05） was obtained from the electronic assembly of 3＇-RACE and 5＇- RACE products. Results This yp05 gene was 787 bp including a 597 bp open reading frame （ORF） and encoded a deduced protein with 199 amino acid residues, and the amino acid sequence of this protein was found similar with the sequences of many fungal manganese-superoxide dismutases in the GenBank with the aid of BLASTp. The transcription ofyp05 gene in Monascus strains was analyzed with the aid of Northern blotting. The transcription of yp05 gene was only detected in Monascus strains, provided that citrinin was produced. Conclusion The transcription of yp05 gene belongs to differential expression genes of citfinin yielded from Monascus and has no correlation with the biosynthesis pathway of red pigments.

BACKGROUND: Few studies have been performed to assess health-related quality of life (HRQOL) in liver transplantation (LT) patients in the mainland of China. This study aimed to investigate the HRQOL of post-LT patients in a single center. METHODS: HRQOL was evaluated by the SF-36 (Chinese version) questionnaire in 60 patients (LT group) who had received LT for benign end-stage liver disease (BELD). Fifty-five patients with BELD (BELD group) and 50 healthy volunteers from the general population (GP group) were also evaluated, and the results were compared among the three groups. RESULTS: There was a significant difference among the three groups in terms of the scores of eight domains in the SF-36 (P0.025), but higher scores for the remaining seven domains (P0.025), but had lower scores for the remaining three domains (P<0.025). Lower family income was found to be associated with reduced physical function and mental health scores (P<0.05). Better education was associated with increased mental health scores (P<0.05). CONCLUSIONS: LT patients generally have a good HRQOL although some respects of their HRQOL remains to be improved. Lower family income and poor education are important factors relating to the poor HRQOL of LT patients.

Extremely rapid evaporation could occur when high-temperature particles contact withlow-temperature liquid. This kind of phenomenon is associated with the engineering safety and the problems inhigh-transient multi-phase fluid and heat transfer. The aim of our study was to design and build an observable ex-periment facility. The first series of experiments were performed by pouring one or six high-temperature particles intoa low saturated temperature liquid pool. The particle's falling-down speed was recorded by a high-speed camera, thuswe can find the special resistant feature of the moving high-temperature particles, which is induced by the high-speedevaporation surrounding the particles. The study has experimentally verified the theory of evaporation drag model.

近年来,异质信息网络特别是基于位置的社交网络(Location-Based Social Networks,LBSN)中的社区发现已成为新兴的研究热点.然而,目前大多数社区发现研究仅考虑基于同质结构的社交网络,显然都已无法有效融合LBSN这种异质网络所包含的多模实体及其多维关系.为了应对该挑战性问题,本文提出了一种新的双重社区聚类与关联方法(Communities Clustering and Associating Method,CCAM),该方法先在LBSN的社交媒体层上,通过信息熵度量用户发布主题之间的相似性,进而再将相似用户兴趣聚类问题转换成求解基于模糊聚类的目标函数以获得重叠的兴趣主题簇结构.然后在地理位置层中,将用户-位置签到关系网络形成的二分图转换为超图模型,并采用超边聚类方式得到用户关于地理位置的兴趣点特征簇.最后,在兴趣主题簇与地理位置簇之间借助中间用户层的社交关系建立这两层异质簇间的关联性表示模型,并通过随机梯度下降法求解模型的局部最优解.在两个真实数据集Foursquare(NYC)和Yelp上的实验结果表明,本文提出的CCAM方法有效融合了用户-媒体发布关系、用户间社交关系、用户-位置签到关系等多维度关系,能准确获得LBSN中紧密关联的用户兴趣主题簇与地理位置簇,使得这双层社区结构不仅在外部结构特征与兴趣内聚性指标上都优于传统算法,并且还在兴趣主题推荐与位置兴趣点推荐方面的平均准确率提高至少32%.
