Conservative management of multi-trauma induced peritonitis: Experience, outcomes, and indications.

Background: The concept of mandatory laparotomy in treating traumatic peritonitis has been increasingly questioned recently.

Aim: To summarize and share the experience of conservative treatment of patients with multi-trauma induced peritonitis.

Methods: A retrospective review was performed on patients with multiple injury induced traumatic peritonitis.

[Spatial and Temporal Distribution and Source Variation of Heavy Metals in Cultivated Land Soil of Xiangzhou District Based on EBK Interpolation Prediction and GDM Model].

In order to explore the spatial and temporal changes in spatial patterns and source changes in heavy metals in Xiangzhou District, 395 and 326 soil samples were collected from cultivated soil in Xiangzhou District in November 2009 and November 2019, respectively. The contents of Cr, Pb, As, Hg, and Cd during these two years were measured. The spatial pattern and variation distribution of five types of heavy metals during these two years were obtained by using the empirical Bayesian Kriging (EBK) method.

[Effects of invasion on the functional groups and niche of benthic crustaceans and fishes in mangrove wetland].

To investigate the effects of invasion on mangrove wetland ecosystem, the benthic crustacean and fish samples were collected using cage nets in Zhangjiang Estuary Mangrove Wetland, Fujian Pro-vince in August 2020, January and April 2021. The five sampling sites included two mangroves ( and ) sites, two sites, and one mudflat site. The abundance, biomass, index of relative importance (IRI), Shannon diversity index (), Pielou evenness index (), and Margalef richness index () were used to quantify the dominant species and species diversity of benthic crustaceans and fishes.
