Effectiveness of Acupuncture in the Treatment of Hyperemesis Gravidarum: A Systematic Review and Meta-Analysis.

Background: Hyperemesis gravidarum (HG) is a common gastrointestinal disease afflicting gravidas. It usually results in hospital admission in early pregnancy.

Objective: Through a meta-analysis, this study intended to explore acupuncture's clinical efficacy in treating HG.

Stable 1T-phase MoS as an effective electron mediator promoting photocatalytic hydrogen production.

Coupling two semiconductors together to construct a Z-scheme type photocatalytic system is an efficient strategy to solve the serious recombination challenge of photogenerated electrons and holes. In this work, we develop a novel composite photocatalyst by sandwiching metallic 1T-phase MoS2 nanosheets between MoO3 and g-C3N4 (MoO3/1T-MoS2/g-C3N4) for the first time. The metallic 1T-phase MoS2 acts as an efficient electron mediator between MoO3 and g-C3N4 to construct an all-solid-state Z-scheme photocatalytic system, resulting in a highly-efficient spatial charge separation and transfer process.

Multiple carrier-transfer pathways in a flower-like InS/CdInS/InO ternary heterostructure for enhanced photocatalytic hydrogen production.

A novel flower-like In2S3/CdIn2S4/In2O3 (ICS) ternary heterostructure (HS) is rationally constructed for the first time by a series of carefully designed procedures. In2O3 nanoflakes are the main constituent units which assemble into a flower-like skeleton structure, and CdIn2S4 nanoparticles are in situ generated on the surface of In2O3 nanoflakes through the transformation of CdS quantum dots (QDs) while In2S3 nanoparticles are in situ produced at the region between CdIn2S4 nanoparticles and In2O3 nanoflakes resulting from a synchronous sulfuration procedure. As expected, the rationally designed ICS ternary HSs display significantly enhanced photocatalytic H2 production, especially ICS5 (sulfurized for 5 h) with the highest H2 evolution rate of 20.

WS /Graphitic Carbon Nitride Heterojunction Nanosheets Decorated with CdS Quantum Dots for Photocatalytic Hydrogen Production.

Two-dimensional/two-dimensional (2D/2D) stacking heterostructures are highly desirable in fabricating efficient photocatalysts because face-to-face contact can provide a maximized interfacial region between the two semiconductors; this largely facilitates the migration of charge carriers. Herein, a WS /graphitic carbon nitride (CN) 2D/2D nanosheet heterostructure decorated with CdS quantum dots (QDs) has been designed, for the first time. Optimized CdS/WS /CN without another cocatalyst exhibits a significantly enhanced photocatalytic H evolution rate of 1174.

Adverse events associated with acupuncture: three multicentre randomized controlled trials of 1968 cases in China.

Background: In order to evaluate the safety of acupuncture in China objectively, we investigated the adverse events associated with acupuncture based on three multicentre randomized controlled trials (RCTs) to assess the safety of acupuncture, identifying the common types of acupuncture adverse events, and analysing the related risk factors for their occurrence.

Methods: This observational study included patients who received acupuncture from three multicentre RCTs respectively for migraine, functional dyspepsia and Bell's palsy. The 1968 patients and their acupuncturists documented adverse events associated with acupuncture after treatment.
