Grain yield is a result of dry matter accumulation and partitioning in rice (Oryza sativa L.). To characterize the genetic basis of dynamics of traits representing dry matter accumulation and partitioning as well as their relationships with each other, composite interval mapping of quantitative trait loci (QTL) was conducted based on time-related phenotypic data obtained from a population of 258 recombinant inbred lines (F12), which was derived from a cross between Lemont (japonica var.) and Teqing (indica var.). A total of twenty-three QTL were identified for leaf weight, stem weight and panicle weight at four measuring stages after heading. However, these three dynamic traits were observed to be controlled by different QTL (genes) at different growth stages. An extreme example was that at least three types of QTL (genes) might be involved in the development of panicle weight. Growth duration, which is closely related to dry matter accumulation and partitioning, was also identified to be significantly affected by four QTL. The close correlations among the studied four traits were explained to some extent by six co-located QTL. Nevertheless, it would be of great importance to distinguish the pleiotropic or linked effects of the co-located QTL. In addition, the chromosome regions or QTL identified in this study were compared with those previously reported for the same or related traits with the same RIL population.

Background: College students are recommended as the target groups for catch-up human papillomavirus (HPV) vaccination. Systematical exploration of awareness, acceptability, and decision-making factors of HPV vaccination among Chinese college students has been limited. Materials and Methods: A multi-center survey was conducted in mainland China between November 2011 and May 2012. College students aged 18-22 years were stratified by their grade, gender, and major for sampling. Socio-demographic and HPV-related information such as knowledge, perceptions, acceptability, and attitudes were collected through a questionnaire. Results: A total of 3,497 undergraduates completed the questionnaire, among which 1,686 were males. The acceptability of the HPV vaccine was high (70.8%). Undergraduates from high-level universities, at lower grade, or with greater prior knowledge of HPV vaccines showed higher acceptability of HPV vaccination ($p_{trend}$ <0.001). Additionally, undergraduates with vaccination experience outside the National Expanded Program on Immunization (OR=1.29; 95%CI: 1.10-1.51) or fear of HPV-related diseases (OR=2.79; 95%CI: 2.28-3.41) were more willing to accept HPV vaccination. General knowledge of HPV vaccine was low among undergraduates, and safety was a major concern (71.05%). The majority of students wished to pay less than 300RMB for HPV vaccine and chose the Chinese Center for Disease Control and Prevention as the most appropriate venue for vaccination. Conclusions: Although most undergraduates demonstrate positive attitudes towards HPV vaccination, challenges pertaining to introduction exist in China. Corresponding proactive education and governmental subsidy to do so are urgently needed by this age-group population. Suggestions and potential strategies indicated may help shape the future HPV vaccination program in China.

Ribonucleic acid interference (RNAi) inhibits the expression of target genes in a sequence-specific manner, and shows potential for gene knockdown in filamentous fungi, in which the locus-specific gene knockout occurs in low frequency. In this study, the function of the repressor of cellulase expression I (ACEI) was verified in Trichoderma koningii (T. koningii) YC01 through RNAi, and ace1-silenced strains with improved cellulase productivity were obtained. An expression cassette that transcribed the interfering double-stranded RNA (dsRNA) of ace1 was constructed and transformed into T. koningii, and the transformants, in which the expression of ace1 was successfully silenced, were selected. As a result of the ace1 gene silencing, the expression levels of the main cellulase and xylanase genes were elevated, and the enhanced production of total proteins, cellulase, and xylanase was observed in the cultivation. In addition, the downregulation of ace1 resulted in an increasing expression of xyr1, but no clear variation in the expression of cre1, which suggested that ACEI acted as a repressor of the xyr1 transcription, but was not involved in the regulation of the cre1 expression. The results of this work indicate that ace1 is a valid target gene for enhancing enzyme production in T. koningii, and RNAi is an appropriate tool for improving the properties of industrial fungi.

Purpose Transarterial chemoembolization (TACE) delivers cytotoxic drugs intra-arterially and induces ischemic necrosis by arterial embolization. Embolization is achieved using a variety of agents that differ widely in particle size and range, deformation, and in vivo arterial distribution. The clinical significance of these differences has not been thoroughly characterized. The present study is to compare the efficacy of Embosphere and Embozene microspheres in TACE therapy for hepatocellular carcinoma. Materials and Methods This retrospective study includes 108 hepatocellular carcinoma (HCC) patients who received TACE/doxorubicin with Embozene (70 patients) or Embosphere (38 patients) at a single medical center. Patient outcomes, including liver function, tumor size, tumor response, and complications after treatment, were analyzed. The change in total target lesion size and tumor response was evaluated according to embolization agent and clinical characteristics. Results The postoperative glutamate oxaloacetate transaminase (mean, 194.5 vs. 147.5; p=0.032) and bilirubin (mean, 1.11 mg/dL vs. 0.73 mg/dL; p=0.016) were higher among patients treated with Embozene, the decrease in the number (55.86±25.55% vs. 41.81±38.51%, p=0.027) and size (56.37±25.91 mm vs. 43.44±37.89 mm, p=0.001) of liver tumors relative to baseline was greater in these patients than in those treated with Embosphere. These greater antitumor effects were achieved using lower doses of doxorubicin than for treatment with Embozene. Minor complications were more common among patients treated with Embosphere than with Embozene. Conclusion These results suggest that Embozene is more efficacious than Embosphere for HCC treatment using TACE/doxorubicin.

Tulou as the famous of its technic of architecture and community lifestyle attract our attention. As the symbol of “Congregate Housing” in the past, how they live in this sharing space? What"s their lifestyle? What are their needs for furniture in the community space in the past? What kind of furniture is suitable for them? Based on these questions, we started with three steps to study it. Firstly, we started to research with Hakka`s lifestyle and people who live in Tulou. Studying Hakka`s lifestyle is the most important metrics to explain why Tulou`s unique architecture, sharing space and furniture formed. After knowing the reason, we needed to find out what their characteristics of lifestyle are. Derived from three aspects which are environment, culture and lifestyle. Secondly, through literature review and field research, we analyzed what the characteristics of their furniture are. We categorized the corresponding examples such as chairs, tables, benches, and cabinets from traditional life and modern life to illustrate how and why they were used for. Lastly, we investigated the suitable furniture for this kind of sharing space and community, and came up with suggestions how we could adapt these characteristics in the design for our modern life. At the end, we found out that how the people of diverse culture and community living formed into Tulou`s lifestyle, how they created a semi-privacy space to coordinate between private and public life, and how they saved more space. These findings can be meaningful to provide theoretical and practical guide for the design of furniture in the sharing space nowadays.
