Abstract

A number of trials have shown that remote ischemic preconditioning (RIPC) could reduce lung injury of patients suffering cardiovascular surgery, pulmonary transplantation surgery and thoracic surgery with one-lung ventilation. However, there is still a controversy over the lung protection of RIPC in patients who suffers different types of surgery. We undertook meta-analysis of the randomized controlled trials to evaluate the effect of remote ischemic preconditioning on clinical outcomes of patients with lung injury.Systematic review and meta-analysis.Perioperative care areas.Adults and infants suffering cardiovascular surgery with lung injury.Remote ischemic preconditioning.The literatures were selected complying with the inclusive and exclusive criteria from the following databases as PubMed, Embase, Medline, Chinese Biomedical Literature and Journal Databases, Chinese Academic and VIP journal full-text Databases. Inclusion criteria includes: (1) Human clinical randomized and controlled trial; (2) the article we included is a clinical randomized controlled study; (3) the article discusses the effect of RIPC on lung injury of patients; (4) the primary evaluation indicators of the inclusive studies included postoperative intensive care unit stay time and mechanical ventilation time; (5) published in the form of full text, any language; (6) the type of operation is cardiovascular surgery; (7) there is no serious COPD, ARDS, respiratory failure and other lung diseases. Articles were excluded if they reported none of the outcomes as follows: postoperative intensive care unit stay time and mechanical ventilation time, human clinical controlled trails, pulmonary protection of RIPC, prospective clinical controlled trials. Two independent reviewers screened abstracts and titles, and selected records following full-text review. Software RevMan5.3 and STATA 12.0 were adopted to perform Meta-analysis.The search finally includes10 studies of 708 patients, 352 patients in RIPC group and 356 patients in control group. The baseline characteristics of patients are no differences in two groups (P 0.05). Compared with control group, RIPC significantly reduced the duration of ICU (P 0.05) and mechanical ventilation time (P 0.05) in RIPC group. In addition, the serum TNF-α and MDA concentration 24 h after operation in RIPC group are significantly lower than control group (P 0.05). However, there are no significant differences between RIPC group and control group in terms of serum IL-6, IL-8 concentrations, A-aDORIPC can decrease pulmonary inflammatory responses, reduce the duration of ICU and mechanical ventilation time, and improve the clinical outcomes of patients with lung injury.

Abstract

Information about changes in, and causes of, land use/land cover (LULC) is crucial for land use resource planning. We investigated the processes involved in LULC change (LUCC) in the Dongjiang Watershed, in Southern China, over a 15-year period to gain a better understanding of the causes of the main types of LUCC. Using a depth transition matrix and redundancy analysis (RDA), the major types and causes of LUCC for each LULC type over the past 15 years were identified. LUCC exhibited obvious net change, relatively low persistence, and high swap change. The swap changes in most LULC types were considered as a strong signal of LULC transformations. The driving forces behind swap changes were quantified and identified through RDA. The results showed that all driving forces played important roles in explaining swap changes of LULC, although the relative effects of these drivers varied widely with both LULC type and time period. Swap changes of the LULC types were generally classified into two categories. Some, e.g., built-up land and wetland, were affected mostly by landform and/or distance factors, while others, e.g., grassland and woodland, were modulated mostly by climate and/or socioeconomic factors. Selected spatial driving forces and local land use policies played important roles in explaining the dominant LUCC types, but on different timescales. These findings may improve understanding of the detailed processes involved in LUCC, landscape transformation, and the causes of LUCC in other areas with extensive LUCC and could help managers plan, design, and implement land resource management.

139. Alterations of the gut microbial community structure modulates the Th17 cells response in a rat model of asphyxial cardiac arrest

Abstract

Th17 cells triggered inflammation is a critical element in cerebral ischemic injury, and the gut microbiota intricately impacts T lymphocytes. Nevertheless, it remains unclear whether the gut microbiota involves in cardiac arrest/cardiopulmonary resuscitation (CA/CPR) induced-brain injury through Th17 cells. The present study investigated the interaction between gut microbiota and Th17 cells in a rat model. We observed that CA/CPR induced the alterations of the gut microbial community structure, and elevated the level of IL-17 in the serum, and a slight infiltration of Th17 cells into the brain. The Th17 cells were increased significantly in the peripheral blood, 28.33 ± 6.18% of these Th17 cells were derived from the Peyer’s patches of small intestine. Furthermore, fecal microbiota transplantation (FMT) from rats with CA/CPR induced Th17 cell response, promoting hippocampal cell apoptosis and declining learning ability and memory in recipient rats. Taken together, CA/CPR-induced alterations of the gut microbial community structure stimulated Th17 cell response which aggravated brain injury.

Abstract

Polycyclic aromatic hydrocarbons (PAHs) are widespread environmental contaminants and pose a severe threat to human health. Here, 38 surface sediment samples collected from the Gaoqiao mangrove wetland in Zhanjiang, south China, were analyzed to determine 16 Environmental Protection Agency (EPA) priority PAHs. Total PAHs concentrations ranged from 33.5 µg/kg to 404.8 µg/kg with an average of 147.7 ± 77.7 µg/kg, inferring a moderate pollution level. Three and four-ring compounds dominated the PAHs composition patterns. Significant positive correlations were observed between the PAHs and the physicochemical properties of the sediments. According to the characteristic molecular ratio method, PAHs in sediments were mainly derived from combustion sources, including the incomplete combustion of liquid fossil fuels, grass, wood, and coal. The result based on the PMF model indicates that the primary combustion sources of PAHs are coal combustion, diesel-powered vehicles, biomass combustion and gasoline-powered vehicles, with a share of 39.01%, 25.21%, 12.72% and 10.48%, respectively. The petrogenic source contributes 12.58% PAHs to the sediments. The mean effects range median quotient (m-ERM-Q) and toxic equivalent method (TEQ) indicate a low comprehensive ecological risk of PAHs in the study area. Still, the evaluation results of effects range low (ERL) suggest that PAHs in the sediment would occasionally have adverse biological effects. Therefore, this situation demands attention and calls for protection strategies in the processes of urbanization and industrialization in south China. [Display omitted] • A baseline of 16 EPA priority PAHs in Gaoqiao mangrove wetland were determined. • Total PAHs concentrations average as 147.7 ± 77.7 µg/kg, and are at a lower pollution level. • Major source include coal combustion, vehicles emission and biomass combustion. • The petrogenic source contributes 12.58% PAHs in the sediments. • The overall ecological risk is low, but there exists occasionally adverse biological effects.
