[Role and mechanism of Cortex Moutan components in inhibiting production of toxic advanced glycation end products (AGEs)].

Advanced glycation end products(AGEs) can lead to many diseases such as diabetes and its complications. In this study, an in vitro non-enzymatic glycosylation reaction model-bovine serum albumin/methylglyoxal(BSA/MGO) reaction system was constructed and incubated with Cortex Moutan extract. High performance liquid chromatography(HPLC) and ultra-high performance liquid chromatography with quadrupole time-of-flight mass spectrometry(UPLC-Q-TOF-MS/MS) were used to detect and identify the active components that inhibited the formation of AGEs in the co-incubation solution of Cortex Moutan extract and MGO, and differential components such as salvianan, paeoniside, benzoylpaeoniflorin, mudanpioside J, galloyloxypaeoniflorin, benzoyloxy-paeoniflorin, 5-hydroxy-3 s-hydroxymethyl-6-methyl-2,3-dihydro benzofuran, and galloylpaeoniflorin were screened out, which were inferred to be the potential active components of Cortex Moutan extract to capture MGO.

The efficacy and safety of remimazolam tosylate versus propofol in patients undergoing colonoscopy: a multicentered, randomized, positive-controlled, phase III clinical trial.

This study aimed to evaluate the efficacy and safety of remimazolam tosylate versus propofol in patients undergoing colonoscopy. In this multicentered, blinded, randomized, active-controlled, non-inferior phase III trial, 384 eligible patients who were about to undergo colonoscopy were randomized as a ratio of 1:1 into remimazolam and propofol group. Procedure success was assessed and defined as the completion of colonoscopy without administration of rescue sedative agent or more than 5 top-ups of trial drug in any 15 minute-period after initial administration of trial drug.

Epitaxial growth of ultrathin layers on the surface of sub-10 nm nanoparticles: the case of β-NaGdF:Yb/Er@NaDyF nanoparticles.

Upconversion core-shell nanoparticles have attracted a large amount of attention due to their multifunctionality and specific applications. In this work, based on a NaGdF sub-10 nm ultrasmall nanocore, a series of core-shell upconversion nanoparticles with uniform size doped with Yb, Er and NaDyF shells with different thicknesses were synthesized by a facile sequential growth process. NaDyF coated upconversion luminescent nanoparticles showed an obvious fluorescence quenching under excitation at 980 nm as a result of energy resonance transfer between Yb, Er and Dy.

Comparison of transcranial ultrasound and cranial MRI in evaluations of brain injuries from neonatal asphyxia.

Full-term infants with early-stage brain injuries from asphyxia were examined with two-dimensional ultrasound and color Doppler to assess the use of ultrasound in evaluating early brain injuries after neonatal asphyxia. The sonographic features of ultrasound and color Doppler were compared to those of magnetic resonance imaging (MRI). Ultrasound was used to monitor the brain parenchyma, lateral ventricles, and cerebral hemodynamics in the asphyxia group and full-term control group 24, 48, and 72 h after birth.

SNP rs1511412 in FOXL2 gene as a risk factor for keloid by meta analysis.

Objective: Determine whether SNP rs1511412 is associated with keloid.

Design And Methods: One large-scale GWAS identified association between SNP rs1511412 in the FOXL2 gene and keloid disease in the Japanese population. However, researchers didn't observe significant association for keloid in Chinese Han population (PBonferroni>0.

[Intraocular lens implantation and coreoplasty for congenital cataract after optical iridectomy].

Objective: To explore the therapeutic method for congenital perinuclear cataract after optical iridectomy.

Methods: Twelve cases (24 eyes) with congenital perinuclear cataract after optical iridectomy were selected. After extracapsular cataract extraction (ECCE) and intraocular lens (IOL) implantation, the sides of the iridectomy were sutured to complete the coreoplasty.
