Epidemiology and Diversity of Rickettsiales Bacteria in Humans and Animals in Jiangsu and Jiangxi provinces, China.

Diseases caused by Rickettsiales bacteria are a global public health problem. To better understand the diversity and origins of Rickettsiales infection in humans and animals, we sampled 134 febrile patients, 173 rodents and 43 shrews, as well as 358 ticks, from two cities in Jiangsu and Jiangxi provinces, China. Our data revealed a relatively high prevalence of scrub typhus cases in both localities.

[An epidemiological investigation of the rabies between 1999 - 2008 in Yancheng city, Jiangsu province.].

Objective: To better understand the epidemiology of rabies during the past ten years in Yancheng city, Jiangsu province.

Methods: Data was collected and analyzed on rabies cases in Yancheng. Density and vaccination rate on Canine, Rate of injured people bit by dogs, and the information of post-exposure prophylaxis were studied.

A serological and molecular survey of hepatitis B in children 15 years after inception of the national hepatitis B vaccination program in eastern China.

The emergence of mutations in the hepatitis B virus (HBV) S gene has threatened the long-term success of vaccination programs since the worldwide introduction of effective vaccines against hepatitis B. This study was conducted on 5,407 children (0-8 years old) in eastern China in 2007. We analyzed the prevalence of HBsAg, anti-HBs, and "a"-determinant mutations in the HBV S gene by microparticle enzyme immunoassays, PCR, and DNASTAR software.

[Study on the efficacy of hepatitis B virus vaccination and its influencing factors among children in rural area of Jiangsu province].

Objective: To evaluate the efficacy of hepatitis B viruse (HBV) vaccination and its influencing factors among children in rural area of Jiangsu province.

Methods: Twenty-five hundred and twenty-two children born after 1998 in rural area were selected as the study population using multistage cluster sampling method. HBsAg and anti-HBs were detected by enzyme linked immunoassay (ELISA) and radio-immunoassay (RIA), respectively.

Single beam one-way imaging through a thick dynamic turbulent medium.

A new method to record an image through a thick dynamic phase distorting medium by using a photorefractive LiNbO3 crystal is demonstrated. The method uses only one beam of light, the object light. By making use of the photorefractive fanning effect, gratings are formed in the LiNbO3 crystal through the interference between the object light and its own fanning light.

[Sequence analysis of Echovirus type 30 isolated from an aseptic meningitis outbreak in northern Jiangsu province in 2003].

Objective: To determine the partial sequence of virus strains causing an aseptic meningitis outbreak in northern part of Jiangsu province in 2003 and to compare them with the same serotype strains isolated in other countries to better understand its genetic characteristics and hereditary trend of development.

Methods: Virus RNA was amplified using two sets of specific enteroviral 3' half of VP1 primers 012/011 and 040/011. Polymerase chain reaction (PCR) products were purified and sequenced.

One-beam recording in a LiNbO3 crystal.

We propose a new way to record images in a photorefractive LiNbO3 crystal. This method involves only a single object light without any reference light. We believe that the recording is attained by fanning holograms that result from interference between the object light and its scattered light.
