Project description:Shigui Ruan. Modeling the transmission dynamics and control of rabies in China. Mathematical Biosciences 286 (2017).
Human rabies was first recorded in ancient China in about 556 BC and is still one of the major public-health problems in China. From 1950 to 2015, 130,494 human rabies cases were reported in Mainland China with an average of 1977 cases per year. It is estimated that 95% of these human rabies cases are due to dog bites. The purpose of this article is to provide a review about the models, results, and simulations that we have obtained recently on studying the transmission of rabies in China. We first construct a basic susceptible, exposed, infectious, and recovered (SEIR) type model for the spread of rabies virus among dogs and from dogs to humans and use the model to simulate the human rabies data in China from 1996 to 2010. Then we modify the basic model by including both domestic and stray dogs and apply the model to simulate the human rabies data from Guangdong Province, China. To study the seasonality of rabies, in Section 4 we further propose a SEIR model with periodic transmission rates and employ the model to simulate the monthly data of human rabies cases reported by the Chinese Ministry of Health from January 2004 to December 2010. To understand the spatial spread of rabies, in Section 5 we add diffusion to the dog population in the basic SEIR model to obtain a reaction-diffusion equation model and determine the minimum wave speed connecting the disease-free equilibrium to the endemic equilibrium. Finally, in order to investigate how the movement of dogs affects the geographically inter-provincial spread of rabies in Mainland China, in Section 6 we propose a multi-patch model to describe the transmission dynamics of rabies between dogs and humans and use the two-patch submodel to investigate the rabies virus clades lineages and to simulate the human rabies data from Guizhou and Guangxi, Hebei and Fujian, and Sichuan and Shaanxi, respectively. Some discussions are provided in Section 7.
Project description:Copy Number Variations (CNVs) were identified performing Comparative Genomic Hybridization (CGH) on 225 patients after whole-genome amplification, using Agilent SurePrint G3 4x180K microarrays. CNVs were further integrated with gene expression (Affymetrix U133+2 arrays) and mutations (targeted DNA resequencing). Complete description of the methods, array quality checks and called segments are available as supplemental material in the corresponding publication.
Project description:Host-virus interaction was analyzed at microRNA expression level. The hypothesis tested in the present study was that rabies virus (RABV) infection affects the microRNA expression in brains of mice and RABV with different virulence induce distinct microRNA expression pattern in host. Results provide important information that RABV infection led to alteration of microRNA expression in brains of mice and FJDRV, a street rabies virus with highly virulence isolated from brain of rabid dog in Fujian provice of China, or ERA, a laboratory-adapted rabies virus with lower virulence induced different microRNA expression pattern, and some them may involved in host defense and immune-related function.

Project description:Neisseria meningitidis is a major cause of bacterial meningitis and septicemia worldwide. Seven new serogroup C meningococci were isolated from two provinces of China in January, 2006. Their PorA VR types were P1.20, 9. Multilocus sequence typing results indicated that they all belonged to ST-7. It is a new serogroup C N. meningitidis sequence type clone identified in China. Here we also present the results of a genomic comparison of these isolates with other 15 N. meningitidis serogroup A and B isolates, which belonged to ST-7, based on comparative genomic hybridization analysis. The data described here would be helpful to monitor the spread of this new serogroup C meningococci sequence type clone in China and worldwide. Keywords: comparative genomic hybridization
Project description:True morels (Morchella spp., Morchellaceae, Ascomycota), a delicious edible mushroom, has rapidly expanded in recent years, especially in China. However, a severe disease of morels, red fruitbody disease, led to very low production of fruiting bodies. The cause reason and the mechanisms under red fruitbody are unclear. Herein, we integrated the transcriptomics and metabolomics data of M. sextelata from red fruitbody group (R) and normal group (N), which was artificial cultivation in Fujian province, China. Transcriptome data revealed the differentially expressed genes (DEGs) between R group and N group were significantly enriched in the pathways of tyrosine metabolism, riboflavin metabolism, and glycerophospholipid metabolism. Similarly, the differential accumulated metabolites (DAMs) were mainly assigned to metabolism categories, including tyrosine metabolism, biosynthesis of plant secondary metabolites, biosynthesis of amino acids, and others. Then, combined analysis of the transcriptome data and metabolome traits revealed that the most enriched pathway was tyrosine metabolism, followed by ABC transporters, alanine, aspartate and glutamate metabolism, and others. In summary, this integration of transcriptomics and metabolomics data of M. sextelata during fruitbody redness implicated several key genes, metabolites, and pathways involved in this disease. We believe that these findings will help us understand the mechanisms under fruitbody redness of M. sextelata and provide new clues for optimizing the methods for its cultivation application.
