Objective: To investigate the immune regulation of "nourishing Yin and Qi, activating blood circulation and detoxifying" in elderly diabetic patients complicated with acute coronary syndrome (ACS), and analyze its possible mechanisms. Methods: 69 diabetic patients aged 50-75 years and complicated with ACS, from March 2019 to February 2020 in the Department of Cardiology and Traditional Chinese medicine (TCM) in the Affiliated Hospital of Youjiang Medical University for Nationalities were randomly divided into control group (34 cases) and treatment group (35 cases). The control group was given western medicine standardized treatment, while the treatment group were treated with HJJR on the basis of routine Western medical treatment, and the therapeutic course for al1 were 2 months. Before and after treating, in the two groups, the levels of pro-inflammatory factors [C-reactive protein (CRP), interleukin-8 (IL-8), tumor necrosis factor - α (TNF - α) and anti-inflammatory factors [IL-10, adiponectin (ADPN)] were detected. The clinical symptoms of chest tightness, chest pain, attacking frequency and duration, palpitation, shortness of breath, fatigue and the total scores of syndromes in the two groups were detected. At the same time, electrocardiogram (ECG) changes and adverse reactions were observed. Results: Compared with before treatment, after treating, the levels of pro-inflammatory factors CRP, IL-8, TNF - α in the two groups were evidently decreased, while the anti-inflammatory factors IL-10 and ADPN were obviously increased, but the changes in the treatment group were more significant (all P

This paper reports that the absorption spectra of H2O+ have been measured by tunable mid-infrared diode laserspectroscopy in the spectral range of 1100–1380 cm-1. The H2O+ ions are generated in an AC glow discharge of the gaseous mixtures of H2O/He and detected with the velocity modulation technique. Forty new lines are assigned to theν2 fundamental band of H2O+(2B1). The observed lines together with other data published previously are fitted to the standard effective Hamiltonian of an asymmetric top, yielding a set of improved rotational constants, spin-rotation constants and their quartic and sextic centrifugal distortion constants for the ν2=1 vibrational state of H2O+.

Anisotropic flow is an important observable in the study of the Quark-Gluon Plasma that is expected to be formed in heavy-ion collisions. With a multiphase transport (AMPT) model we investigate the elliptic($\emph{v}_{2}$), triangular($\emph{v}_{3}$), and quadrangular($\emph{v}_{4}$) flow of charged particles in Pb+Pb collisions at $\sqrt{s_{\rm NN}}$ = 5.02 TeV. Then We compare our flow results with the published ALICE flow results. We found our AMPT simulated results are consistent with ALICE experimental data.

We demonstrate a 10.7 Gb/s-line-rate L-band wavelength-division-multiplexer (WDM) loop transmission over a 1890-km standard single-mode fibre (SSMF) with a 100-km amplifier spacing as well as non-return-to-zero (NRZ) format. The dispersion compensating fibre (DCF) plus chirped fibre Bragg grating (CFBG) is employed for hybrid inline dispersion compensation. The power penalty of each channel is less than 3 dB after three-loop transmission. The experimental results show that high-performance CFBGs can be successfully used in ultra-long haul (>1000 km) WDM systems. We also point out that the all-CFBG compensation scheme is not suitable for re-circulating loop transmissions.

The effects of initial field state and thermal environment on quantum nonlocality and linear entropy in an atom–field coupling system are investigated. We found that if the cavity is lossless and the reservoir is in vacuum, the atom–field state can exhibit quantum nonlocality periodically and the linear entropies of the atom and the field also oscillate periodically with a period the same as that of quantum nonlocality. And if the cavity dissipation is very weak and the average photon number of the reservoir is very small, the quantum nonlocality will be lost and the linear entropies of the atom and the field oscillate with a decreasing amplitude. The rapidity of the loss of the quantum nonlocality depends on the amplitude of the initial squeezed coherent state, the cavity damping constant κ and the average photon number N of the thermal reservoir. The stronger the field and the larger the constant κ and the average photon number N could be, the more rapidly the nonlocality decreases.

The property of quantum nonlocality in the atom-field coupling system via degenerate Raman processes with cavity damping is investigated. It is found that if the cavity dissipation is very weak, the atom-field state can exhibit quantum nonlocality periodically. The rapidity of the loss of the quantum nonlocality depends on the amplitude of the initial coherent state and the cavity damping constant. The stronger the field is and the larger the damping constant could be, the more rapidly the nonlocality decreases.

A simple model has been developed to describe the Zeeman patterns of far-infrared laser magnetic resonance spectra of the monobromomethyl radical CH2Br observed at 447.3 and 671.1mum. A satisfactory agreement between the experimental spectra of the radical and their simulation with this simple model has been achieved. This approach can be used to gain further information about the structure and the spectrum of this interesting radical.

A global analysis of all available and identified spectra of the PO2 radical has been performed. In this analysis, the infrared spectra of the nu(3) band, the microwave and far infrared laser magnetic resonance transitions in the ground state are fitted simultaneously to the effective Hamiltonian for asymmetric top molecules. Since the analysis absorbs reliable experimental data extensively, it bears the most precise and most complete set of molecular constants for PO2. These molecular constants can, be used to reproduce the spectra of PO2 accurately. Attention is also paid to the similarity and difference between PO2 and NO2.

Based on the global analysis of all available and reliable data for isotopic species 14NmO(m=16,17,18), the 14N16O rovibrational spectral lines are calculated with very high accuracy and completely agree with previous results. These lines with relative intensities can be achieved as an infrared frequency standard in the spectral range 1600-5600 cm-1. The calculated rovibrational transitions of 14NmO(m=17,18) have the same accuracy as that for 14N16O although their data are rare due to their small natural abundance.

Twenty-five new R-branch lines of the v2 (1−←0+) band of H3O+ are measured using diode laser velocity modulation spectroscopy between 1070 and 1230 cm−1. The H3O+ ions are produced in a high voltage ac discharge with water diluted in helium. The observed lines together with all the previously published measurements are fit to the standard vibration-rotational Hamiltonian of an oblate symmetric top, yielding a set of improved molecular constants. All the sextic centrifugal distortion constants for both 0+ and 1− states are determined precisely. The observed R(13,0) transition is shifted about -0.129 cm−1 from its calculated value, indicating that a near degeneracy exists between the (13, 0)+ and (13, 3)− ground-state rotation-inversion levels.

We have investigated the atomic coherent population trapping in a multilevel laser-induced continuum structure system including cascade two-photon processes, in which two sets of quasicontinua of excited levels to be modeled as the Bixon-Jortner quasicontinuum are laser-embedded into a previously structureless atomic continuum. The condition leading to the atomic coherent population trapping and the coherent population trapping state are given explicitly. And the effects of the Fano factors, the laser intensities and the detunings on the amount of population trapped in the atomic bound states and the populations distributed in the two sets of quasicontinua are also examined.

Starting from the Watson A-reduced Hamiltonian and considering the infrared transitions with DeltaK(a) = 0, DeltaK(c) = +/-1 (A-type) or DeltaK(a) = +/-1, DeltaK(c) = +/-1 (B-type), and the far-infrared transitions with DeltaK(a) = 0, +/-2 and DeltaK(c) = +/-1, we calculate all the possible infrared absorption and far-infrared emission transitions of the v(4) and v(9) bands of 1,1-difluoroethylene (CH2CF2) pumped by 10P10 and 10P12 CO2 laser lines. We assign four previously unassigned CH2CF2 far-infrared laser lines (291.3 mum, 339.3 mum, 349.51 mum and 657.9 mum), where K-a and K-c represent the quantum number K of the limiting prolate top and the limiting oblate top, respectively. The 291.3 mum line is identified as being generated from the cascade transition. The assignment of the 288.5 mum line by Lafferty et al. (J. Mol. Spectrosc. 87(1981)416) is also confirmed.

High order centrifugal distortion terms have been derived and added to the effective Hamiltonian of asymmetric top molecules. Based on this Hamiltonian, a program in Fortran 77 has been developed for spectral analysis of asymmetric top molecules. The high order centrifugal distortion terms are found to be non-negligible even for the low-lying rotational transitions of molecules, such as H2 18O, subjected to severe centrifugal distortion effect, and for the high-lying rotational transitions of molecules, such as 14N16O2 subjected to the moderate centrifugal distortion effect.

The absorption spectrum of a driven two-level atom in a frequency tunable cavity with injected squeezed vacuum is investigated. The line shape of the spectra depends on the relative phase between the driving field and the squeezed vacuum, and the frequency detuning between the driving field and the cavity mode. Line narrowing and probe gain can occur and be enhanced by adjusting the phase and detuning.

An intracavity CO laser magnetic resonance spectrometer with homogeneous dc electric field applied via a pair of parallel Stark plates in the absorption cell is used to measure the electric dipole moments of free radicals. Taking advantage of the high sensitivity and high resolution of this technique and the Stark effect, highly-resolved saturated absorption spectra of the ν = 1-0 transition of 15N16O in the ground state X2Π3/2 have been successfully observed in the presence of a low electric field. The electric dipole moment of NO in the electronic ground state is determined as µ = 0.1566±14 D (Debye) from the analysis of the observed spectra, confirming that, combined with the Stark field, the laser magnetic resonance technique can be an effective and reliable approach for the precise measurement of electric dipole moments of free radicals, especially unstable ones.
