Exposure to extreme temperatures can hinder the development of insects and even reduce their survival rate. However, the invasive species exhibits an impressive response to different temperatures. This study aims to identify important transcriptional changes of occupying different temperature habitats by performing RNA sequencing on populations originating from three regions of China.

Objective: To compare non-tuberculous mycobacterial pulmonary disease (NTMPD) diagnosis by metagenomic next-generation sequencing (mNGS) with Bactec mycobacterial growth indicator tube (MGIT) 960.

Methods: A total of 422 patients with suspected NTMPD in Shanghai Pulmonary Hospital between January 2020 and May 2021 were retrospectively analyzed; 194 were diagnosed with NTMPD. The diagnostic performance of mNGS and MGIT 960 for NTMPD was assessed.

Article Synopsis
  • NTMs are rising, with a study in Shanghai exploring patient outcomes and treatment factors from 2014 to 2018, focusing on NTM pulmonary disease (NTMPD).
  • The most prevalent NTM species were MAC (50%), and two others, with treatment success rates varying significantly based on the species, being highest for one specific type.
  • Key risk factors for treatment failure include specific NTM species, high ESR levels, retreatment history, and older age.

Invasive species often encounter rapid environmental changes during invasions and only the individuals that successfully overcome environmental stresses can colonize and spread. Chromatin remodeling may be essential in environmental adaptation. To assess the functions of imitation switch (ISWI) in invasive Middle East-Asia Minor 1 (MEAM1) cryptic species, we cloned and characterized the MEAM1 gene and determined its functions in response to thermal stress.

Shexiang Baoxin Pill (SBP), a traditional Chinese medicine formula, is commonly used to treat cardiovascular disease (CVD) in China. However, the complexity of composition and targets has deterred our understanding of its mechanism of action. Using network pharmacology-based approaches, we established the mechanism of action for SBP to treat CVD by analyzing protein-protein interactions and pathways.

We developed a high-throughput bead-based suspension array for simultaneous detection of 20 respiratory tract pathogens in clinical specimens. Pathogen-specific genes were amplified and hybridized to probes coupled to carboxyl-encoded microspheres. Fluorescence intensities generated via the binding of phycoerythrin-conjugated streptavidin with biotin-labeled targets were measured by the Luminex 100 bead-based suspension array system.

This study aims to investigate the characteristics of genomic variation of pandemic A/H1N1/2009 influenza virus isolated in Fujian Province, China. Complete genome sequence analysis was performed on 14 strains of pandemic A/H1N1/2009 influenza virus isolated from Fujian during 2009-2012. All virus strains were typical low-pathogenic influenza viruses, with resistance to amantadine and sensitivity to neuraminidase inhibitors.

Objective: To study the cross-resistance between rifampin and rifabutin in multidrug resistant Mycobacterium tuberculosis complex strains, and therefore to provide laboratory data for using rifabutin in the treatment of multidrug resistant tuberculosis.

Methods: The MIC(90) of rifabutin and rifampin against 99 multidrug resistant Mycobacterium tuberculosis clinical strains were determined by microplate assays. Statistical analysis was performed by using the χ(2) test and the t test.

WU polyomavirus (WUPyV), a new member of the genus Polyomavirus in the family Polyomaviridae, is recently found in patients with respiratory tract infections. In our study, the complete genome of the two WUPyV isolates (FZ18, FZTF) were sequenced and deposited in GenBank (accession nos. FJ890981, FJ890982).

Article Synopsis
  • The study focused on the genetic and epidemic traits of influenza A (H3N2) viruses in Fujian Province, China, from 1996 to 2004, using phylogenetic analysis of HA1 gene sequences.
  • Researchers found that mutations in the HA1 gene led to significant antigenic drift in the viruses over eight flu seasons, with key changes occurring at specific antibody binding sites.
  • The findings suggest the importance of ongoing monitoring for mutations in HA1 to track H3 isolates as the influenza virus evolves, particularly in South Asia.

Objective: To study the epidemiology and etiologic characteristics of a Dengue fever outbreak in Fuzhou from the beginning of September to the end of October in 2004 in order to understand the source of infection.

Methods: Data on descriptive epidemiology was collected to study the characteristics and related factors to the epidemic. Dengue virus was isolated through the use of C6/36 cell line while viral serotypes were identified by indirect immunofluorecent assay with type-specific monoclonal antibody.
