Development of a prognostic gene signature and exploration of P4HA1 in the modulation of cuproptosis in colorectal cancer.

Cuproptosis, a newly identified form of cell death, has drawn increasing attention for its association with various cancers, though its specific role in colorectal cancer (CRC) remains unclear. In this study, transcriptomic and clinical data from CRC patients available in the TCGA database were analyzed to investigate the impact of cuproptosis. Differentially expressed genes linked to cuproptosis were identified using Weighted Gene Co-Expression Network Analysis (WGCNA).

Long-term efficacy of a hepatitis E vaccine.

Background: Hepatitis E virus (HEV) is a leading cause of acute hepatitis. The long-term efficacy of a hepatitis E vaccine needs to be determined.

Methods: In an initial efficacy study, we randomly assigned healthy adults 16 to 65 years of age to receive three doses of either a hepatitis E vaccine (vaccine group; 56,302 participants) or a hepatitis B vaccine (control group; 56,302 participants).

[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.

FDJS03 isolates causing an outbreak of aseptic meningitis in China that evolved from a distinct Echovirus 30 lineage imported from countries of the Commonwealth of Independent States.

We compared echovirus 30 strains (FDJS03) which caused an outbreak of aseptic meningitis in China in 2003 with other human enterovirus B strains. Sequencing of the complete genome of FDJS03_84, a representative strain from this outbreak, revealed a mosaic structure with a putative recombination spot within the 2B gene. It was most similar to a strain of the same serotype, E30-14125-00, in the 5' half of the genome but was almost equidistant to all strains analyzed in most of the 3' half of the genome.

Molecular characterization of rabies virus isolates in China during 2004.

Human rabies cases have been on the rise during the past few years in China and a total of 2651 cases were reported in 2004. To better understand the current rabies epidemics in China, we isolated rabies viruses from dogs and humans from five provinces and characterized these isolates genetically by sequencing the entire nucleoprotein (N) gene. Comparison of the N genes among these isolates revealed 86.

[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.

Echovirus 30, Jiangsu Province, China.

An outbreak of aseptic meningitis occurred in the northern area of Jiangsu Province in China from January to July in 2003. A total of 1,681 cases were involved in this outbreak, and 99% of patients were <15 years of age. To identify the etiologic agent, 66 cerebrospinal fluid specimens were tested by cell culture.
