Development and Application of Global Health Events-Mental Stress Scale for Assessment of Medical Staff's Acute Mental Stress Responses.

Background: Medical workers have been increasingly involved in emergent public health events, which can lead to severe stress. However, no standardized, officially recognized, unified tool exists for mental distress measurement in medical workers who experienced the public health events.

Purpose: In the present study, we propose the Global Health Events-Mental Stress Scale (GHE-MSS), as a revised version of the Impact of Event Scale-Revision (IES-R), for assessment of medical workers' acute mental stress responses within one month and their chronic mental stress responses within six months after major health events.

Chronic Progression of Lung Cancer Recurrence After Surgery: Warning Role of Postoperative Pneumonia.

Purpose: The association between the process of postoperative pneumonia and lung cancer recurrence remains elusive in lung cancer surgery. Herein, the association between postoperative pneumonia and lung cancer recurrence was investigated, emphasizing the warning role of postoperative specific pneumonia in primary lung cancer resection patients.

Methods: The occurrence of postoperative pneumonia was assessed in 4-6 months (PPFS), 7-12 months (PPST), and lung cancer recurrence within 1 year (LRO) in 332 patients.

Comparison of a Novel Muscle Training Device with Conventional Rehabilitation Training in Motor Dysfunction of Lower Limb Patients: A Pilot Study.

Background: Postoperative functional training for fracture or osteoarthritis is mainly focused on functional self-exercise, which aims to recover the function of the lower limbs.

Purpose: To compare the function and life quality recovery in patients with fracture or arthritis treated with novel muscle training device (NMT) or conventional rehabilitation training (CRT) following surgery.

Patients And Methods: A total of 32 fracture patients were randomly divided into the NMT or the CRT groups.

Characteristics of Renal Function in Patients Diagnosed With COVID-19: An Observational Study.

The aim of the study was to analyze the characteristics of renal function in patients diagnosed with COVID-19. In this retrospective, single-center study, we included all confirmed cases of COVID-19 in a tertiary hospital in Guangdong, China from January 20, 2020 to March 20, 2020. Blood and urine laboratory findings related to renal function were summarized, and the estimated glomerular filtration rate (eGFR) and endogenous creatinine clearance (Ccr) were also calculated to assess the renal function.

Contingency Nursing Management in Designated Hospitals During COVID-19 Outbreak.

Background: In December 2019, early cases of COVID-19 were identified in Wuhan, China. By late January 2020, it was evident that COVID-19 was rapidly spreading and represented a national health emergency. In order to contain the spread of COVID-19, China adopted a centralized treatment plan by appointing designated hospitals in each region.

Syntheses, crystal structures and optical properties of two one-dimensional germanophosphates: HRbGe(HPO) and CsGe(HPO)(OH).

Germanophosphates, as a young class of metal phosphates, have been less reported but might possess more diverse structural types and potential applications. Here, two one-dimensional (1D) alkali-metal germanophosphates (GePOs), namely, hydrogen hexakis(μ-hydrogen phosphato)digermaniumtrirubidium, HRbGe(HPO) (1), and caesium bis(μ-hydrogen phosphato)(μ-hydroxido)germanium, CsGe(HPO)(OH) (2), have been prepared by the solvothermal method. Compound 1 shows 1D [Ge(HPO)] chains along the c axis formed by GeO octahedra and PO tetrahedra, with Rb cations dissociated between the chains.

A facile synthesis of two new IR optical perovskites based on 1,4-diazabicyclo[2,2,2]octane with a high laser damage threshold.

The main commercial infrared nonlinear optical (IR NLO) crystals, typically, AgGaS2, have some inherent disadvantages, for example, low laser damage threshold (LDT) or relatively poor stability, which limit their wide application. Here, we discover two new IR optical perovskites based on 1,4-diazabicyclo[2,2,2]octane, namely, (H2dabco)(PbCl3)2 (1) and (H2dabco)(H2PbBr6)·H2O (2). 1 and 2 crystallize in the noncentrosymmetric space groups P43212 and P63mc, respectively, displaying a broad transparent range with high transmission.

A new method for the preparation of a [Sn(HPO)]Br SHG-active polar crystal via surfactant-induced strategy.

Herein, unprecedented NLO-brominated tin hypophosphites, namely [Sn(HPO)]Br, were discovered via a facile surfactant-induced method, which displayed a moderate powder SHG intensity (3.0 × KDP) in type - I phase matching behavior. This complex has high chemical and thermal stability at room temperature.

[Assessment on the COD discharge status of municipal wastewater treatment plant in a city of China].

Based on the statistical theory, the paper collected routine monitoring data for 3 years of 11 municipal wastewater treatment plants with secondary treatment or enhanced secondary treatment in a northern city in China, and analysis of the discharge concentration distribution of COD showed a Delta-lognormal distribution. On this basis, referring to the formulation methods of water pollutant discharge limits used in the USA, the paper studied and assessed the discharge status of COD of the municipal wastewater treatment plants in the city, including the daily maximum and the monthly average discharge status, and came to the conclusion that the daily maximum discharge status met the first grade A class discharge standard (50 mg · L(-1)) required by the Discharge Standard of Pollutants for Municipal Wastewater Treatment Plant (GB 18918-2002). Meanwhile, the assessment conclusion was obtained for the monthly average discharge status, and the conclusions were discussed.

Knockdown of Rho-associated protein kinase 1 suppresses proliferation and invasion of glioma cells.

Rho-associated protein kinase 1 (ROCK1), a serine/threonine protein kinase, affects cell invasion and migration by changing the status of the cytoskeleton. In recent years, ROCK1 was found to be overexpressed in a variety of tumors. However, the information of ROCK1 in glioma still remains elusive.

A ligand-chirality controlled supramolecular hydrogel.

We report a novel example of ligand-chirality finely controlled in situ supramolecular hydrogel formation based on the coordination of phenylalanine (Phe) to Cu(II) with higher selectivity over other metal ions. As decreasing both enantiomeric excesses (ee%) of ligand Phe towards its D- and L-forms, the gelation ability of Phe-Cu(II) supramolecular metallogelator was found to be weakened and eventually disappeared, which likely resulted from the stereoselectivity of the ligand Phe. Intermolecular hydrogen bonding, hydrophobic and/or pi-pi stacking interactions were also found to be essential for forming the metallogel.

Kinetic mechanism of methanol decomposition on Ni(111) surface: a theoretical study.

The decomposition of methanol on the Ni(111) surface has been studied with the pseudopotential method of density functional theory-generalized gradient approximation (DFT-GGA) and with the repeated slab models. The adsorption energies of possible species and the activation energy barriers of the possible elementary reactions involved are obtained in the present work. The major reaction path on Ni surfaces involves the O-H bond breaking in CH(3)OH and the further decomposition of the resulting methoxy species to CO and H via stepwise hydrogen abstractions from CH(3)O.

Characterization of methoxy adsorption on some transition metals: a first principles density functional theory study.

Based on the gradient-density functional theory, calculation results of methoxy adsorption on Au(111), Ag(111), Cu(111), Pt(111), Pd(111), Ni(111), Rh(111), and Fe(100) surfaces are presented, and a consistent picture for some key physical properties determining the reactivity of metals appears. These eight metals belong to two groups: either with filled d electrons (group IB) or with unfilled but more than half filled d electrons (group VIII). The calculated adsorption energies are quite in agreement with the experimental data as well as the previous theoretical calculation results.
