Soil organic carbon stocks increased across the tide-induced salinity transect in restored mangrove region.

Blue carbon in mangrove ecosystems contributes significantly to the global carbon cycle. However, large uncertainties maintain in the soil organic carbon (SOC) storage throughout the tide-induced salinity and alkalinity transect in the mangrove restoration region in Southern China. Total 125 soil samples were obtained to detect the SOC content and physicochemical properties. The mean SOC content of each layer ranged from 6.82 to 7.86 g kg-1, while the SOC density ranged from 2.99 to 11.41 kg m-2, increasing with soil depths. From different land covers in the study region, the SOC content varied from 4.63 to 9.71 g kg-1, increasing across the salinity and alkalinity transect, while the SOC density fluctuated from 3.01 kg m-2 in mudflats to 10.05 kg m-2 in mangrove forests. SOC concentration was favorably linked with total nitrogen (r = 0.95), and total phosphorus (r = 0.74), and negatively correlated with Cl- (r = - 0.95), electrical conductivity (r = - 0.24), and total dissolved solids (r = - 0.08). There were significant logarithmic relationships between SOC content and the concentrations of clay (r = 0.76), fine silt (r = 0.81), medium silt (r = - 0.82), and coarse silt (r = - 0.78). The spatial patterns of SOC concentration were notably affected by soil texture, physicochemical properties, and land-cover type, providing essential reference for future investigations of blue carbon budget in restored mangrove forests.

Complete chloroplast genome of a wild-type Gardenia jasminoides ellis (rubiaceae) adapted to island climate.

Gardenia jasminoides Ellis is a traditional aromatic and medicinal plant in China. Here, the complete chloroplast genome of a wild-type gardenia adapted to island climate was assembled. The assembled genome was 155,247 bp in length, with four typical regions, i.e., a large single-copy (LSC) region (85,414 bp), a small single-copy (SSC) region (18,235 bp) and two inverted repeats (IRs) regions (25,799 bp each). In total, 138 genes were predicted, including 90 protein-coding genes, 40 tRNA genes and eight rRNA genes. The overall GC content of the chloroplast genome was 37.5%. The chloroplast genome would provide more information for the phylogeography and phylogeny study of G. jasminoides.

Consensus of experts on perioperative care of chronic rhinosinusitis under the concept of enhanced recovery after surgery / 中国实用护理杂志

Objective:To form the consensus of nursing experts in accelerated rehabilitation surgery in perioperative period of chronic rhinosinusitis in order to promote the standardized development of accelerated rehabilitation surgery nursing in perioperative period of chronic rhinosinusitis in China.Methods:By consulting the literature evidence and combining with the clinical practice experience, the consensus draft was formed by more than 5 nurses in charge of nursing. According to the Grading of Recommendations Assessment, Development and Evaluation System, (GRADE), the evidence quality and recommendation grade of each item were evaluated.Results:The consensus covered 4 aspects of pre-hospital care guidance, including preoperative care, postoperative care, and discharge care for chronic rhinosinusitis, with a total of 12 items, including health education, individualized treatment guidance, network platform use, adaptive training, diet management, activity guidance, pain management, and discharge follow-up.Conclusions:The content of this consensus covers all aspects of accelerated rehabilitation surgery nursing during perioperative period of chronic rhinosinusitis, which is scientific, rigorous and authoritative, and can provide reference and guidance for accelerated rehabilitation surgery nursing in the perioperative period of chronic rhinosinusitis.

Two Types of 2D Layered Iodoargentates Based on Trimeric [Ag3I7] Secondary Building Units and Hexameric [Ag6I12] Ternary Building Units: Syntheses, Crystal Structures, and Efficient Visible Light Responding Photocatalytic Properties.

With mixed transition-metal-complex, alkali-metal, or organic cations as structure-directing agents, a series of novel two-dimensional (2D) layered inorganic-organic hybrid iodoargentates, namely, Kx[TM(2,2-bipy)3]2Ag6I11 (TM = Mn (1), Fe (2), Co (3), Ni (4), Zn (5); x = 0.89-1) and [(Ni(2,2-bipy)3][H-2,2-bipy]Ag3I6 (6), have been solvothermally synthesized and structurally characterized. All the title compounds feature 2D microporous layers composed by [Ag3I7] secondary building units based on AgI4 tetrahedra. Differently, the [Ag3I7] trimers are directly interconnected via corner-sharing to form the 2D [Ag6I11](5-) layer in compounds 1-5, whereas two neighboring [Ag3I7] trimers are initially condensed into a hexameric [Ag6I12] ternary building unit as a new node, which further self-assembles, leading to the 2D [Ag6I10](4-) layer in compound 6. The UV-vis diffuse-reflectance measurements reveal that all the compounds possess proper semiconductor behaviors with tunable band gaps of 1.66-2.75 eV, which lead to highly efficient photocatalytic degradation activities over organic pollutants under visible light irradiation compared to that of N-dotted P25. Interestingly, all the samples feature distinct photodegradative speeds at the same reaction conditions, and compound 1 features the highest photocatalytic activity among the title phases. The luminescence properties, band structures, and thermal stabilities were also studied.
