Article Abstract

Background: Fujian Province has one of the highest reported incidences of hepatitis B virus infection in China. This study aimed to provide a theoretical framework for preventing and controlling hepatitis B in Fujian Province, and to assess the trends and the spatial-temporal distribution patterns of hepatitis B in this region.

Methods: Data on hepatitis B cases were extracted from the National Notifiable Infectious Disease Surveillance System. Spatial autocorrelation analysis, trend surface analysis, and spatial-temporal scanning statistics were used to identify the spatial and aggregation patterns at the county level. The Joinpoint was used to assess the reported incidence trends.

Results: The average reported incidence of hepatitis B in Fujian from 2012 to 2021 was 14.46/10,000 population, with 583,262 notified cases. The age-adjusted reported incidence of hepatitis B decreased from 17.44/10,000 population in 2012 to 11.88/10,000 population in 2021, with an average reduction in the annual percentage change of 4.5%. There were obvious spatial-temporal aggregation characteristics in hepatitis B cases, and a high-incidence area was located in eastern Fujian. Spatio-temporal scanning statistics revealed four levels of aggregation of hepatitis B reporting rates. The first level of aggregation area included Minhou, Gulou, Jin'an, Taijiang, and nine other districts and counties.

Conclusion: The incidence of hepatitis B is declining in Fujian Province. Spatial clusters of hepatitis B cases in Fujian Province were identified, and high-risk areas in eastern Fujian still exist. Closely monitoring the general patterns in the occurrence of hepatitis B and implementing focused control and preventative strategies are important.

The closely related cytokines Interleukin-4 (IL-4) and IL-13 regulate the Th2 immune response by interacting with their specific receptor complexes. MicroRNAs (miRNAs) modulate various biological pathways through mechanisms that either repress mRNA translation or promote messenger RNA degradation. The miRNA miR-126b is implicated in fish embryonic development.

As a member of the inflammatory caspases, Caspase-1 can increase the host inflammatory response against pathogen invasion and also function dominantly in apoptosis. In this study, we cloned and obtained two transcripts of Caspase-1 in large yellow croaker (Larimichthys crocea), namely Lc-Caspase-1_tv1 and Lc-Caspase-1_tv2. The ORF of Lc-Caspase-1_tv1 is 1,239 bp, whereas Lc-Caspase-1_tv2 is 1,167 bp in length, encoding a protein of 412 and 388 aa, and both of which contains a CARD and a CASc domain.

As climate change, urbanization, and marine exploitation intensify, understanding nearshore island ecosystem services (IESs) is essential for ensuring ecological protection and sustainable development. This study maps the spatiotemporal dynamics of six key ecosystem services (ESs) across 295 nearshore Chinese islands, including food production (FP), water yield (WY), soil conservation (SC), carbon storage (CS), and habitat quality (HQ) (2000-2022), and tourism and recreation (TR) (2012-2022). Using spatial autocorrelation, Slope trend analysis, per-pixel Pearson correlation, and K-means clustering, the study quantifies the trade-offs and synergies, identifies constraint characteristics, and delineates ecological functional zones for island classification.
