In this paper, we investigate the quantum fluctuations of subharmonic reflected field from a triple-resonant degenerate optical parametric amplifier(OPA) inside coupled optical resonators, which is driven by the squeezed beam at signal frequency. By controlling the relative phase between the pump beam and the injected signal beam, we can see the quantum fluctuation in the phase direction and amplitude direction due to the parametric down-conversion process in the cavity. Thus, the phase sensitive operation of the compression field is realized due to the quantum interference between the harmonic field of the down converter of OPA and the inner field of the coupled optical resonator. We verified the quantum coherent phenomena of OPA in coupled optical resonators and phase-sensitive manipulations of quantum entanglement for quantum information processing. We realized the electromagnetically induced transparency-like(EIT-like) effect and the optical parameter conversion process at the same time in one optical device. These properties can favor higher manipulation precision and control efficiency, which is more suitable for the integration of quantum-on-chip systems, laying a foundation for the practical application of quantum information.

This study aims to explore the interdecadal variation of South Asian High(SAH) and its relationship with SST(sea surface temperature) of the tropical and subtropical regions by using the NCEP/NCAR monthly reanalysis data from 1948 to 2012, based on the NCAR CAM 3.0 general circulation model. The results show that: 1) the intensity of SAH represents a remarkable interdecadal variation characteristic, the intensity of SAH experienced from weak to strong at the late 1970 s, and after the late 1970 s, its strength is enhanced and the area is expanded in the east-west *** expansion degree is greater westward than eastward, while it is opposite in summer. 2) Corresponding to the interdecadal variation of SAH intensity, after the late 1970 s, the divergent component of wind field has two ascending and three descending areas. Of the two ascending areas, one is located in the East Pacific, the other location varies with the season from the Indian Ocean in winter to the South China Sea and West Pacific in summer. Three descending areas are located in the north-central Africa, the East Asia and the Middle Pacific region respectively. 3) Corresponding to the interdecadal variation of SAH intensity, the rotational component of wind field at the lower level is an anomalous cyclone over the South China Sea and West Pacific in summer, while in winter, it is an anomalous cyclone over the Indian Ocean, and an anomalous anticyclone over the equatorial Middle Pacific. 4) Numerical simulations show that the interdecadal variation of SAH is closely related to the SST of the tropical and subtropical regions. The SST of Indian Ocean plays an important role in winter, while in summer, the SST of the South China Sea and West Pacific plays an important role, and the SST of the East Pacific also plays a certain role.

INTRODUCTION Atopic dermatitis （AD） is a common chronic inflammatory skin disorder that is characterized by dry skin and disturbed skin barrier functions. Mutations in the filaggrin （FLG） gene, the gene coding profilaggrin/filaggrin, have a great impact on the epidermal barrier function and are an important predisposing factor for AD. However, in both Europeans and Asians,

Objective The present study aimed to investigate the potential roles of spinal microglia and downstream molecules in the induction of spinal long-term potentiation （LTP） and mechanical allodynia by tetanic stimulation of the sciatic nerve （TSS）. Methods Spinal LTP was induced in adult male Sprague-Dawley rats by tetanic stimulation of the sciatic nerve （0.5 ms, 100 Hz, 40 V, 10 trains of 2-s duration at l 0-s intervals）. Mechanical allodynia was determined using von Frey hairs. Immunohistochemical staining and Western blot were used to detect changes in glial expression of inter- leukin-18 （IL-l 8） and IL-18 receptor （IL-18R）. Results TSS induced LTP of C-fiber-evoked field potentials in the spinal cord. Intrathecal administration of the microglial inhibitor minocycline （200 ~tg/20 gL） 1 h before TSS completely blocked the induction of spinal LTP. Furthermore, after intrathecal injection of minocycline （200 ~tg/20 ~tL） by lumbar puncture 1 h before TSS, administration of minocycline for 7 consecutive days （once per day） partly inhibited bilateral allodynia. Immunohistochemistry showed that minocycline inhibited the sequential activation of microglia and astrocytes, and IL- 18 was predominantly colocalized with the microglial marker Iba-1 in the spinal superficial dorsal horn. Western blot revealed that repeated intrathecal injection of minocyctine significantly inhibited the increased expression of IL-18 and IL- 18Rs in microglia induced by TSS. Conclusion The IL-18 signaling pathway in microglia is involved in TSS-induced spinal LTP and mechanical allodynia.
