Efficacy of Duohuojisheng decoction monotherapy for the treatment of knee osteoarthritis: A protocol of a systematic review of randomized controlled trials.

Background: This systematic review investigates the efficacy and safety of Duohuojisheng decoction (DHJSD) monotherapy for the treatment of patients with knee osteoarthritis (KOA).

Methods: We searched relevant studies on DHJSD monotherapy for KOA from the databases of CENTRAL, EMBASE, MEDLINE, Cumulative Index to Nursing and Allied Health Literature, Allied and Complementary Medicine Database, Chinese Biomedical Literature Database, China National Knowledge Infrastructure, VIP Information, and Wanfang Data from the inception to January 1, 2019. Two researchers independently selected studies, collected data, and assessed the methodology quality by using Cochrane risk of bias tool.

A solenoidal synthetic field and the non-Abelian Aharonov-Bohm effects in neutral atoms.

Cold neutral atoms provide a versatile and controllable platform for emulating various quantum systems. Despite efforts to develop artificial gauge fields in these systems, realizing a unique ideal-solenoid-shaped magnetic field within the quantum domain in any real-world physical system remains elusive. Here we propose a scheme to generate a "hairline" solenoid with an extremely small size around 1 micrometer which is smaller than the typical coherence length in cold atoms.

Mimicking interacting relativistic theories with stationary pulses of light.

One of the most well known relativistic field theory models is the Thirring model. Its realization can demonstrate the famous prediction for the renormalization of mass due to interactions. However, experimental verification of the latter requires complex accelerator experiments whereas analytical solutions of the model can be extremely cumbersome to obtain.

Luttinger liquid of photons and spin-charge separation in hollow-core fibers.

In this work we show that light-matter excitations (polaritons) generated inside a hollow-core one-dimensional fiber filled with two types of atoms, can exhibit Luttinger liquid behavior. We first explain how to prepare and drive this quantum-optical system to a strongly interacting regime, described by a bosonic two-component Lieb-Liniger model. Utilizing the connection between strongly interacting bosonic and fermionic systems, we then show how spin-charge separation could be observed by probing the correlations in the polaritons.

[Expression of interleukin-6 in rat model of doxorubicin-induced nephropathy].

Objective: The pathogenesis of minimal change nephrotic syndrome (MCNS) remains unclear. This study aimed to investigate the expression of interleukin-6 (IL-6) in rats with doxorubicin-induced nephropathy and its possible roles in the pathogenesis of MCNS.

Methods: Eighty-three male Wistar rats were randomly assigned into a control group (n=32) and a nephropathy group (n=51).
