This paper analyzes the intervention effect of auricular acupoint pressing therapy and nursing measures in a case of acute pancreatitis combined with gastrointestinal dysfunction, and summarizes the relevant nursing experience. On the basis of improving the nursing evaluation, Traditional Chinese medicine auricular acupoint pressing treatment was adopted, and the psychological care, nutritional support and dietary care of patients were strengthened. Traditional Chinese Medicine auricular point pressing treatment can effectively improve the symptoms of acute pancreatitis combined with impaired gastrointestinal function, and accelerate the stage of full-feeding of enteral nutrition support. Moreover, it is easy-to-operate and relatively safe in clinical practice.

In order to investigate the application of high temperature resistant profragrances in the aromatic modification of polyester, three POSS-based profragrances (M1, M2 and M3) were successfully synthesized by Schiff reaction using different fragrance aldehyde molecules and octa (γ-chloroaminopropyl) polyhedral oligomeric silsesquioxane (OCAP-POSS) as raw materials based on molecular hybridization method. The structure of the profragrances was characterized by nuclear magnetic resonance spectrum, infrared spectrum and ultraviolet-visible spectrum. We investigated the fragrance release kinetics characteristics of the profragrances in the environments, including simulated human acidic sweat, neutral and alkaline soap solutions. The results show that the thermal decomposition temperature of all the three profragrances exceeds 285 °C, indicating their good thermal stability. The structure of profragrances has significant effect on their release performance, with M1 reaching an equilibrium release rate of 57.86%, but M3 only 33.32%, and the sustained release time is in the order of M1(29 h)>M2 (16 h)>M3 (12 h). The profragrances are relatively stable in the soap environment, but exhibit a slow release in acidic sweat. The release behaviors follow the first-order reaction kinetics characteristics.

Satisfying the animals feed demand from the forage supply by grasslands remains a major challenge in the grassland–livestock ecosystem. To provide an alternative forage sources, this study conducted two feeding trials in the summer of 2015 and 2016 to compare the nutritive value, digestibility and nutrients utilization of native pasture (NH) and oat forage (OT) fed to Tibetan sheep (Ovis aries). Twelve Tibetan sheep with a mean body weight of 39.11 ± 3.66 kg in 2015 and 27.97 ± 2.69 kg in 2016 were use in this study. The experiment was 2 (year: 2015 and 2016) by 2 (forage: NH and OT) factorial. Data on proximate analysis, fiber fraction and nutrients digestibility were collected and analyzed using general linear model. However, the crude protein (CP) and water‐soluble carbohydrates contents in OT were higher (P <.001) than those in NH by 7.81–8.93% and 46.40–47.05%, respectively. In contrast, the neutral detergent fiber (NDF) and acid detergent fiber contents were higher (P <.001) in NH by 14.28–15.78% and 15.62–18.00%, respectively. The dry matter digestibility coefficient in OT (0.82 in 2015 and 0.79 in 2016) was significantly higher than that in NH (0.68 in both years). In addition, the OT diet had higher (P <.001) organic matter, NDF and CP digestibilities. Animals fed OT retained significantly more nitrogen (2.66 g/day in 2015 and 1.93 g/day in 2016) than those fed NH (0.96 g/day in 2015 and 0.42 g/day in 2016). The digestible energy and metabolizable energy were higher (P <.001) in OT than in NH. Our data indicated that Tibetan sheep urinary N excretion increased by 0.726 g with increase of 1 g in the nitrogen intake. Conclusively, the OT had higher nutritive value than NH and could therefore use to satisfy livestock demand and reduce the grazing pressure on grasslands. [ABSTRACT FROM AUTHOR]

Zero-dimensional perovskites have received extensive attention in recent years due to their unique structural properties, including large exciton binding energies, strong quantum confinement effects, and good stability. Target products were precisely constructed from existing organic–inorganic hybrid perovskite material phase-transition systems via exploiting the ideas of molecular design, modification, and assembly. Herein we report an organic–inorganic hybrid perovskite compound, [C6H18F6N3SbBr6] (1), with excellent reversible phase transition and dielectric switching properties. The symmetry of the structure was reduced upon introducing fluorine atoms to the ethylamine moiety. The results showed that compound 1 had a narrow bandgap of 2.90 eV and three distinct dielectric anomalies at ∼175.9, 205.9, and 257.5 K. UV-vis absorption spectra and density-functional theory (DFT) calculations confirmed this bandgap. It was revealed that the octahedral framework of inorganic [SbBr6]3− was the main contributor to this bandgap. This work highlights that the substitution of hydrogen atoms by halogens has important effects on the structural phase transition mechanism and physical properties of the synthesized product, therefore, it provides an effective strategy for the synthesis of novel organic–inorganic hybrid perovskite phase-transition materials.

Piezoelectric responsive molecular ferroelectrics have become a research hotspot due to their advantages of simple fabrication, environmental friendliness, light weight and good mechanical flexibility. Here we proposed a new kind of multipole rare earth molecular ferroelectric, ((nBu)4N)3[Ce(NO3)4(SCN)2]((CH3CH2CH2CH2)4N = tetrabutylammonium) (1). Compound 1 undergoes a high temperature ferroelectric phase transition at 408 K. It is worth noting that compound 1 has a narrow band gap of 2.61 eV, flexible switchable SHG effect, moderate spontaneous polarization Ps = 3.6 μC cm−2, and piezoelectric constant = 3 pC N−1. The results show that these findings provide ideas for exploring multifunctional rare earth molecular ferroelectrics with a piezoelectric effect. [ABSTRACT FROM AUTHOR]

Bistable switches (electrical switching between "ON" and "OFF" bistable states) have gradually developed into an ideal category of highly intelligent materials, due to their significant applications in optical technology, signal processors, data storage and other switchable media applications in the field of electrical devices. Here, we successfully designed and synthesized [(FC6H4C2H4NH3)2MCl4]n(FC6H4C2H4NH3+)=deprotonated 4‐fluoro‐ phenethylamine; M=Cd (1), Mn (2)), which realized the coupling of thermo‐dielectric switching characteristics, semi‐conductor characteristics and photo‐luminescent properties. DSC (differential scanning calorimetry) and dielectric measurements show that 1 is a sensitive dielectric bistable switch between the high dielectric (ON) and low dielectric (OFF) states. The temperature‐variable single crystal structure shows that the both 1 and 2 undergo a high‐temperature reversible phase transition around 383 K/380 K, which is caused by the order‐disordered transformation of organic cations and the slight distortion of the inorganic framework. In particular, 1 shows outstanding switchable dielectric behavior and semiconducting properties. Further, 1 and 2 emit strong green and yellow luminescence at 527 and 595 nm, respectively.

The tetracyanopyridine (4-cyanopyridine and 3-cyanopyridine) was reacted with rare earth nitrates (Ln = La, Gd, Er) under hydrothermal conditions by the Demko-Sharpless method, and four rare earth tetrazolium ionic compound were synthesized safely and effectively, named [Ln(H2O)8 ⋅ 3(p-TPD) ⋅ 2(p-HTPD) ⋅ 7H2O], (Ln = La( 1), Gd(2), Er (3), p-TPD = 4-tetrazolpyridine), [Ln(H2O)8 ⋅ 3(m-TPD) ⋅ 6H2O], (m-TPD = 3-tetrazolpyridine, Ln = Er(4)). These four rare earth tetrazolium ionic compounds were characterized by the single crystal X-ray diffraction, infrared spectroscopy, thermogravimetry, dielectric properties, X-ray powder diffraction. The X-ray single crystal structure analysis shows that the four rare earth tetrazolium compounds were all ionic, and the rare earth metal ions and ligands were in two different layers. The [Ln(H2O)8]3+ structure unit and p-TPD and water molecules formed a cationic layer through hydrogen bonding, while p-TPD and p-HTPD formed an anion layer through π-π stacking and hydrogen bonding. The cation layer and anion layer alternately form a regular network structure. Moreover, the dielectric properties tests indicate that the compounds 1, 2 have good dielectric properties.
