Interventional reperfusion for acute embolism of the middle cerebral artery trunk with contralateral internal carotid artery congenital absence.

Internal carotid artery congenital absence with acute embolism of the middle cerebral artery trunk is very rare. A 65-year-old female with a history of hypertension and atrial fibrillation was admitted to the neurology department of our hospital. Computed tomography of the head and neck showed no carotid canal of the petrous portion of the temporal bone; digital subtraction angiography (DSA) showed no left internal carotid artery and the right middle cerebral artery trunk occlusion.

Focal intramural hematoma as a potential pitfall for iatrogenic aortic dissection during subclavian artery stenting: A case report.

Background: Iatrogenic aortic dissection (IAD) is a rare but fatal complication of interventional treatment for the proximal supra-aortic large vessels. Several cases of IAD after endovascular treatment of subclavian artery have been reported. Nevertheless, the pathogenesis of IAD is still unclear.

Diagnostic value of contrast-enhanced harmonic endoscopic ultrasonography in predicting the malignancy potential of submucosal tumors: a systematic review and meta-analysis.

Objectives: Contrast-enhanced harmonic endoscopic ultrasonography (CH-EUS) utilizes the second-harmonic signals from contrast microbubbles located in the vessels to improve the detectability of microcirculation. Many studies have used CH-EUS to stratify the malignancy risk of submucosal tumors (SMTs), discriminate gastrointestinal stromal tumors (GISTs) from benign SMTs, and predict the malignancy of GISTs based on the regularity of vessels or enhancing patterns. The aim of this study was to conduct a meta-analysis to evaluate the diagnostic performance of CH-EUS in the differential diagnosis of SMTs.

Endoscopic needle-knife treatment for symptomatic esophageal Zenker's diverticulum: A meta-analysis and systematic review.

Objective: The aim of this study was to assess the efficacy and safety following endoscopic management of Zenker's diverticulum (ZD) using a needle-knife technique.

Methods: A systematic search of PubMed, Embase and Cochrane library databases was performed. All original studies reporting efficacy and safety of needle-knife technique for treatment of ZD were included.

Rapamycin enhances the anti-angiogenesis and anti-proliferation ability of YM155 in oral squamous cell carcinoma.

YM155, a small molecule inhibitor of survivin, has been studied in many tumors. It has been shown that YM155 inhibited oral squamous cell carcinoma through promoting apoptosis and autophagy and inhibiting proliferation. It was found that YM155 also inhibited the oral squamous cell carcinoma-mediated angiogenesis through the inactivation of the mammalian target of rapamycin pathway.

Long non-coding RNA UCA1 contributes to the progression of oral squamous cell carcinoma by regulating the WNT/β-catenin signaling pathway.

With the development of functional genomics studies, a mass of long non-coding RNAs (LncRNA) were discovered from the human genome. Long non-coding RNAs serve as pivotal regulators of genes that are able to generate LncRNA-binding protein complexes to modulate a great number of genes. Recently, the LncRNA urothelial carcinoma-associated 1 (UCA1) has been revealed to be dysregulated, which plays a critical role in the development of a few cancers.

The Association of Maternal Body Composition and Dietary Intake with the Risk of Gestational Diabetes Mellitus during the Second Trimester in a Cohort of Chinese Pregnant Women.

Objective: To investigate the association of maternal body composition and dietary intake with the risk of gestational diabetes mellitus (GDM).

Methods: A total 154 GDM subjects and 981 controls were enrolled in a prospective cohort study in 11 hospitals from May 20, 2012 to December 31, 2013. Bioelectrical impedance analysis and dietary surveys were used to determine body composition and to evaluate the intake of nutrients in subjects at 21-24 weeks' gestation (WG).

Identification and validation of argininosuccinate synthase as a candidate urinary biomarker for major depressive disorder.

Background: Major depressive disorder (MDD) is a debilitating psychiatric mood disorder. However, no objective laboratory-based test is yet available to aid in the diagnosis of this disorder.

Methods: In order to identify urinary protein biomarker candidates for MDD, the differential proteomic analysis of urine samples from first-episode drug-naïve MDD subjects and healthy controls (HC) was carried out by using two-dimensional gel electrophoresis separation followed by MALDI-TOF/TOF-MS/MS identification.

Combined Metabolomics and Proteomics Analysis of Major Depression in an Animal Model: Perturbed Energy Metabolism in the Chronic Mild Stressed Rat Cerebellum.

Major depressive disorder (MDD) is a highly prevalent, debilitating mental illness of importance for global health. However, its molecular pathophysiology remains poorly understood. Combined proteomics and metabolomics approaches should provide a comprehensive understanding of MDD's etiology.

Sex-specific urinary biomarkers for diagnosing bipolar disorder.

Sex-based differences are prominent in affective disorders, but there are no biomarkers available to support sex-specific, laboratory-based diagnostics for male and female bipolar disorder (BD) patients. Here, a NMR-based metabonomic approach was used to preliminarily identify sex-specific urinary metabolite biomarkers for diagnosing male and female BD patients. A male-specific biomarker panel consisting of four metabolites (α-hydroxybutyrate, choline, formate, and N-methylnicotinamide) effectively discriminated between male BD and healthy controls (HC) subjects, achieving an area under the receiver operating characteristic curve (AUC) of 0.

[Residues and health risk assessment of sulfonamides in sediment and fish from typical marine aquaculture regions of Guangdong Province, China].

Concentrations of sulfonamides including sulfadiazine (SDZ), sulfadimidin (SM2) and sulfamethoxazole (SMX) in sediments, muscle and liver tissues of 7 kinds of fish species collected from two marine aquaculture regions along the coast of Guangdong Provice were determined by high performance liquid chromatography (HPLC) equipped with a ultraviolet detector. Assessment of the health risks were conducted based on the values of maximum residue limits (MRL) and acceptable daily intake (ADI). The results showed that sulfonamides were found in all the sediment samples.

Combined application of NMR- and GC-MS-based metabonomics yields a superior urinary biomarker panel for bipolar disorder.

Bipolar disorder (BD) is a debilitating mental disorder that cannot be diagnosed by objective laboratory-based modalities. Our previous studies have independently used nuclear magnetic resonance (NMR)-based and gas chromatography-mass spectrometry (GC-MS)-based metabonomic methods to characterize the urinary metabolic profiles of BD subjects and healthy controls (HC). However, the combined application of NMR spectroscopy and GC-MS may identify a more comprehensive metabolite panel than any single metabonomic platform alone.

CpG oligodeoxynucleotides discriminately enhance binding capacity of human naïve B cells to Hepatitis B virus epitopes.

CpG oligodeoxynucleotides (CpG ODN) have the potential to enhance the antigen-presenting cells function of human naïve B cells. In this study, we aim to define the effect of CpG ODNs on the binding capacity of human naïve B cells for different Hepatitis B virus (HBV) epitopes. Three HLA-A2 restricted epitopes were selected to incubate with CpG ODN-primed human naïve B cells.

[Investigation of quinolones in aquaculture environment of the Pearl River Delta].

The concentrations and distributions of three sorts of quinolones (norfloxacin, ciprofloxacin and enorfloxacin) in water, sediments and the tissues of 8 kinds of fishes from 7 sites in Pearl River Delta aquaculture regions (freshwater and marine) were determined by high performance liquid chromatography (HPLC) with fluorescence detector. Results showed that no quinolones were found in either fresh waterborne or marine water. Norfloxacin, ciprofloxacin and enorfloxacin in sediments collected from freshwater aquaculture region ranged from 5.

[Ion fluorescence probe detecting the formation of triplex DNA].

The fluorescence of Tb3+ is not quenched after the rare earth ion is combined with DNA. The fluorescence intensity is related not only to the kinds of bases of DNA but also to the kinds of DNA. The rare earth ion Tb3+ was used as the fluorescence probe to detect the formation of triplex DNA.
