In order to design an adsorption material with higher selectivity to U(Ⅵ) while ensuring a higher adsorption capacity, g-C3N4 and ammonium dihydrogen phosphate were used as raw materials to prepare P-C3N4 by thermal copolymerization. The Ag3PO4/P-C3N4 composite adsorption material was prepared by in-situ co-precipitation method using disodium hydrogen phosphate and silver nitrate. The results of adsorption experiments show that the adsorption capacity of Ag3PO4/P-C3N4 composite adsorbent for U(Ⅵ) reaches 524.6 mg/g at room temperature; the distribution coefficient to U(Ⅵ) reaches 6.13×103 mL/g with competing ions such as Na+, K+, Mg2+, Ca2+, Sr2+, Zn2+, Ni2+ and Co2+ in solution. XPS analysis result shows that the N- and P-containing functional groups in the Ag3PO4/P-C3N4 composite adsorption material may participate in the U(Ⅵ) adsorption process. Therefore, the Ag3PO4/P-C3N4 composite adsorption material is one kind of adsorption material with higher adsorption capacity and higher U(Ⅵ) selectivity.

The purpose of the experiment was to study the feasibility of using the larvae and residues of Hermetia illucens transformed into pig dung as animal feed additives for laying hens. A total of 1 000~1 200 four-day-old Hermetia illucens were inoculated on surface of 1 000 kg of fresh pig manure, and the mixture of the worm body and the remaining residue (BFM) was dried and crushed, and its nutritional components were detected. A total of 216 270-day-old Beijing Red Brown laying hens were randomly divided into three groups, with three replicates in each group and 24 chickens in each replicate. The laying hens in control group were fed with a basic diet, and each experimental group added 5%, 15% and 25% BFM to the basic diet. The experimental period was 8 w. The results showed that 1 000 kg of pig manure with a water content of about 77% was dried and crushed after biotransformation by Hermetia illucens larvae, leaving 168 kg (water content 86 g/kg) of dry matter of biotransformation mixture. BFM nutritional analysis showed that the content of crude protein, crude fat, crude fiber and calcium of BFM were 205, 46, 131 and 26 g/kg, respectively, while the content of VB1, VB2 and VB6 were 30.4, 30.2 and 230.2 mg/kg, respectively, which were rich in trace elements and essential amino acids. The laying rate of group 1 was the highest, at 85.7%, and the average egg weight increased with the increase of BFM addition. The addition of BFM has a significant impact on egg yolk weight, protein weight, egg shape index, and eggshell thickness. Compared with control group, the serum TP content and SOD activity of group 2 were significantly increased ( P<0.05). The TC content in group 2 and group 3 was significantly reduced ( P<0.05), while the T-AOC and GSH content were significantly increased ( P<0.05). The activity of CAT in group 1 and group 2 significantly increased ( P<0.05), the content of MDA in each experimental group significantly decreased ( P<0.05). The study indicates that BFM can used as an animal feed additive in laying hens, with a suitable addition amount of 15%. [ABSTRACT FROM AUTHOR]

Background: No specific antiviral agent against hand foot and mouth disease (HFMD) is available for clinical practice today. Objective: To evaluate the efficacy and safety of Jinzhen oral solution in treating uncomplicated HFMD. Methods: In this randomized, double-blind, placebo-controlled trial, 399 children aged 1 to 7 years with laboratory confirmed HFMD were randomized to receive Jinzhen oral liquid or placebo 3 times daily for 7 days with a 3-day follow-up. The primary outcomes were time to the first disappearance of oral ulcers and vesicles on hand or foot and time to the first normalization of temperature (fever clearance). Results: There were 199 children enrolling into the Jinzhen group including 79 with fever and 200 into the placebo group including 93 with fever. Jinzhen reduced the time to the first disappearance of oral ulcers and vesicles on hand or foot to 4.9 days (95% CI, 4.6 to 5.2 days), compared with 5.7 days (95% CI, 5.4 to 6.0 days) in the placebo group (P = 0.0036). The median time of fever clearance was shorter in the 79 children who received Jinzhen (43.41 hrs, 95% CI, 37.05 to 49.76) than that in the 93 children who received placebo (54.92 hrs, 95% CI, 48.16 to 61.68) (P = 0.0161). Moreover, Jinzhen reduced the risk of symptoms by 28.5% compared with placebo (HR, 0.7150, 95% CI, 0.5719 to 0.8940, P = 0.0032). More importantly, treatment failure rate was significantly lower in the Jinzhen group (8.04%) compared with that in the placebo group (15.00%) (P = 0.0434). The incidence of serious adverse events did not differ significantly between the two groups (9 in Jinzhen group vs. 18 in placebo, P = 0.075). Conclusions: Children with HFMD may benefit from Jinzhen oral liquid treatment as compared with placebo.

In the title compound, [ZnCl(2)(C(18)H(16)N(2)O(2))](n), the Zn(II) ion is tetra-hedrally coordinated by two Cl atoms and by two N atoms from different 1,4-bis-(pyridin-2-ylmeth-oxy)benzene ligands. The ligand shows a non-planar configuration, in which the dihedral angles between the two terminal pyridine rings and the linking benzene ring are 7.86 (12) and 70.74 (11)°. The flexible ligand coordinates to the Zn(II) ions, generating an infinite chain propagating along [001].

In the title compound, [Co(NO(3))(2)(C(18)H(16)N(2)O(2))(2)](n), the Co(II) ion is located on an inversion center and is six-coordinated in an octa-hedral environment defined by four N atoms of the pyridine rings and two O atoms of the nitrate anions. The ligands link the Co(II) ions into a linear chain running along [201]. One O atom of the nitrate ligand is disordered over two positions with site-occupancy factors of 0.59 (4) and 0.41 (4).

In the title compound, [Ag(C(12)H(11)NO(2))(2)]NO(3)·H(2)O, the Ag(I) ion is coordinated by two N atoms from two different 4-(4-pyridyl-meth-oxy)phenol ligands, generating a nearly linear coordination geometry with an N-Ag-N angle of 167.1 (1)°. A three-dimensional supra-molecular network is built from the uncoordinated nitrate anion, the water mol-ecule and the cation through O-H⋯O hydrogen bonds.
