Comparative Study of Ultrasonography and Ultra-Widefield Fundus Photographs for Measurements of the Diameter of Choroidal and Retinal Tumors.

Introduction: Measurement of the largest basal dimension (LBD) of intraocular tumors is important as a prognostic parameter. To evaluate the potential value of true color ultra-widefield fundus photography for measuring tumors, we compared LBD measurements of choroidal and retinal tumors using a color ultra-widefield fundus camera with clinical estimation based on indirect ophthalmoscopy and standardized ophthalmic ultrasound.

Methods: The LBD of 148 choroidal and retinal tumors in 148 patients seen at Tongren Hospital were measured using ultra-widefield fundus photography and compared with measurements obtained using B-scan ultrasonography and clinical estimates based on indirect ophthalmoscopy.

Methods: The cross-sectional community-based Kailuan Diabetic Retinopathy Study included patients with type 2 diabetes without diabetic retinopathy who participated in the community-based longitudinal Kailuan study and who had undergone ocular fundus photography, kidney function assessment, and optical coherence tomographic angiography (OCT-angiography) for the assessment the retinal perfusion density (PD) and retinal VD.

Thickness of individual layers at the macula and associated factors: the Beijing Eye Study 2011.

Background: Diagnosis and follow-up of retinal diseases may be improved if the thickness of the various retinal layers, in addition to the total retinal thickness, is taken into account. Here we measured the thickness of the macular retinal layers in a population-based study group to assess the normative values and their associations.

Methods: Using spectral-domain optical coherence tomographic images (Spectralis®, wavelength: 870 nm; Heidelberg Engineering Co, Heidelberg, Germany), we measured the thickness of the macular retinal layers in participants of the population-based Beijing Eye Study without ocular diseases and without systematic diseases, such as arterial hypertension, hyperlipidemia, diabetes mellitus, cardiovascular diseases, previous myocardial infarction, cerebral trauma and stroke.

Ocular Axial Length and Diabetic Retinopathy: The Kailuan Eye Study.

Purpose: To examine the role of ocular axial length as an ocular parameter for the prevalence and severity of diabetic retinopathy (DR).

Methods: The cross-sectional Kailuan Diabetic Retinopathy Study included patients with diabetes who participated in the community-based longitudinal Kailuan Study and who had undergone ocular fundus photography. The fundus photographs were graded using the Early Treatment of Diabetic Retinopathy Study criteria.

Pseudoginsenoside-F11 alleviates oligomeric β-amyloid-induced endosome-lysosome defects in microglia.

Amyloid accumulation in the brain is the major pathological hallmark of Alzheimer disease (AD). Amyloid beta (Aβ) is cleared by the endosomal-autophagy-lysosomal system, which is impaired in AD pathogenesis by an unknown mechanism. Pseudoginsenoside-F11 (PF11), an ocotillol-type ginsenoside, has been demonstrated to decrease the level of Aβ in APP/PS1 mouse brain and to protect neurons by inhibiting the activation of microglia in vitro.

Anti-hypertrophic and anti-apoptotic effects of short peptides of potato protein hydrolysate against hyperglycemic condition in cardiomyoblast cells.

Cardiomyocyte hypertrophy is a critical pathological phenomenon observed in diabetic cardiomyopathy. Various molecular events including the Calcineurin/nuclear factor of activated T-cell (NFAT) mediated signaling contributes to the pathogenesis of cardiac hypertrophy. While different new therapeutic interventions are investigated in order to overcome pathological hypertrophic effects, recent studies on peptide hydrolysates from common foods have gained interest.

Long-term Progression and Risk Factors of Fundus Tessellation in the Beijing Eye Study.

Neurological mechanism of Xiaochaihutang's antidepressant-like effects to socially isolated adult rats.

Objectives: Xiaochaihutang (XCHT) has antidepressant effects in multiple animal models of depression in our previous studies. But the antidepressant effects and exact mechanisms of XCHT in a rat model of chronic social isolation stress (CSIS) have never been studied. We therefore aimed to investigate the effects of XCHT on depressive/anxiety-related behaviours of CSIS-exposed rats and understand the neurological mechanism involving neurogenesis.

Treatment of aging oily wastewater by demulsification/flocculation.

The aging oily wastewater (AOW) from Tarim oilfield in China was treated by demulsification/flocculation. A novel sewage treatment agent (YL-7) was developed using a cationic surfactant (LY) and flocculants (polydimethyl diallyl ammonium chloride (PDMDAAC)/polyaluminum chloride (PAC)). At an YL-7 dosage of 320 mg L(-1) at 323 K for 90 min, the oil content of AOW was reduced from 728.

Antidepressant-like effects of Xiaochaihutang in a rat model of chronic unpredictable mild stress.

Ethnopharmacological Relevance: Xiaochaihutang (XCHT) has been used in China for thousands of years to treat "Shaoyang syndrome", which involves depressive-like symptoms. However, few studies have investigated its antidepressant effects and pharmacological mechanism of action. The present study was designed to confirm the antidepressant effect of XCHT using a chronic unpredictable mild stress (CUMS) model and explore its potential mechanism of action by investigating the monoamine neurotransmitters (dopamine and 5-hydroxytryptamine) and neurotrophins (BDNF and NGF).

Neuroprotective effect of pseudoginsenoside-f11 on a rat model of Parkinson's disease induced by 6-hydroxydopamine.

Pseudoginsenoside-F11 (PF11), a component of Panax quinquefolism (American ginseng), plays a lot of beneficial effects on disorders of central nervous system. In this paper, the neuroprotective effect of PF11 on Parkinson's disease (PD) and the possible mechanism were investigated in a rat PD model. PF11 was orally administered at 3, 6, and 12 mg/kg once daily for a period of 2 weeks before and 1 week after the unilateral lesion of left medial forebrain bundle (MFB) induced by 6-hydroxydopamine (6-OHDA).

Xiaochaihutang prevents depressive-like behaviour in rodents by enhancing the serotonergic system.

Objectives: Xiaochaihutang (XCHT) has been used in China for thousands of years to treat 'Shaoyang syndrome', which involves depressive-like symptoms. However, no studies were conducted to demonstrate its antidepressant effect and mechanism. This study was designed to confirm the antidepressant effect of XCHT and explore its mechanism using the pharmacological methods.

Oligomeric Aβ-induced microglial activation is possibly mediated by NADPH oxidase.

Recent studies have shown that oligomeric amyloid-β (oAβ) peptide can potentially activate microglia in addition to inducing more potent neurotoxicity compared with fibrillar Aβ (fAβ); however, its mechanisms of action remain unclear. This study was designed to investigate the possible mechanisms involved in the microglial activation induced by oAβ in BV-2 microglial cells. The results showed that oAβ induced activated properties of microglia, including higher proliferative capacity as well as increased production of reactive oxygen species, nitric oxide (NO), tumor necrosis factor-α (TNF-α), and interleukin-1β (IL-1β).
