Constructing efficient and continuous transport pathways in membranes is a promising and challenging way to achieve the desired performance in the pervaporation process. The incorporation of various metal-organic frameworks (MOFs) into polymer membranes provided selective and fast transport channels and enhanced the separation performance of polymeric membranes. Particle size and surface properties are strongly related to the random distribution and possible agglomeration of MOFs particles, which may lead to poor connectivity between adjacent MOFs-based nanoparticles and result in low-efficiency molecular transport in the membrane.

In this study, bioaerosols were collected from seven different stages of an A²O process WWTP. The component characteristics were analyzed by bacterial culture and high-throughput sequencing.

This study aims to identify the situation of natural human enterovirus 71 (HEV71) and coxsackievirus A16 (CVA16) infections in children before 2008 in China.
Results: Retrospective seroepidemiologic studies of HEV71 and CVA16 were performed with 900 serum samples collected from children ≤5 years of age in 2005.

Objective: To study the situation of 1- 5-years-old children's antibody against Coxsackievirus A group 16 strain (CVA16) in Guangdong, Heilongjiang,Yunnan Province and Xinjiang Uygur Autonomous Regions, China, 2005, it can offer scientific evidences for preventing and controlling CVA16 causative hand-food and mouth disease.
Methods: Using microneutrilization test, to study 503 serum samples randomly selected from sera collected in 2005.
Results: Positive rate of anti-CVA16 antibody were 41.

Objective: To understand the epidemiological and genetic characteristics of rubella viruses in China (excluded Hongkong, Macao and Taiwan areas, the same below) from 2007 to 2008, and to provide the basis for the development of rubella immunization strategy.
Methods: Both rubella epidemiology data from rubella disease surveillance information management system and rubella virology data from National measles Laboratory surveillance data base were analyzed.
Results: The reported rubella incidence rate was 5.

Objectives: To investigate human enterovirus 71(HEV71) antibody levels among children in China in recent years, to find the epidemic status of hand, foot and mouth diseases (HFMD) in children, and to provide a scientific base for the HFMD prevention and control.
Methods: 371 sera specimens were colleted from 371 children of 1-6 years old in 3 counties of 3 provinces in 2005. All sera proposed to be detected for measles antibodies investigation.

Objective: The study was conducted to analyze the epidemiological characteristics of mumps in China (Hong Kong, Macau and Taiwan excluded) from 2004 to 2006 and to provide basic data for mumps control.
Methods: Descriptive epidemiological analysis was conducted based on the data of epidemic parotitis from National Notifiable Disease Reporting System and mumps virus surveillance database from Nation Measles Lab.
Results: The annual incidence rates of parotitis cases during 2004-2006 were 17.

Objective: Observe the effect of Ribavirin on reducing the EV71 replication, inactivating EV71 and protecting the RD-A cells against the EV71 infection in vitro.
Methods: Using the EV71 isolated from Anhui Fuyang HFMD outbreak, the effect of Ribavirin on RD-A cells during the EV71 infection was observed.
Results: In the experiment of Ribavirin inhibiting the EV71 replication, comparing with the no-Ribavirin-dealed virus control group, the group of 1:640 dilution of Ribavirin delayed the CPE for 2 days, while the normal cell group was growing very well.

A three-dimensional image of a living cell is helpful for cell secretion study. In this report, the three-dimensional fluorescence deconvolution microscopy for observing living cells was studied, because this technique can obtain a quick three-dimensional imaging with minimal fluorescence quenching and cytotoxicity for living cell observation. The property of three-dimensional point spread function (PSF) of imaging system was analyzed.
