Radiological findings of contrast-induced encephalopathy following cerebral angiography: A case report.

Introduction: Contrast-induced encephalopathy (CIE) is a rare complication associated with the use of contrast media. New contrast agents make contrast complications increasingly rare. The diagnosis of CIE is challenging, particularly in patients with acute ischemic stroke.

Triterpenoids From With Their Anti-inflammatory and Inhibited Proliferation of Rheumatoid Arthritis-Fibroblastoid Synovial Cells Activities.

One new 3,4--17,13-friedo-lanostane triterpenoid heilaohuacid A (), one new 3,4--17,14-friedo-lanostane triterpenoid heilaohuacid B (), five new 3,4-lanostane triterpenoids heilaohuacids C-D () and heilaohumethylesters A-C (), one new 3,4--cycloartane triterpenoid heilaohuacid E (), and one new -lanostane triterpenoid heilaohuacid F (), together with twenty-two known analogues (), were isolated from heilaohu. Their structures were determined using HR-ESI-MS data, 1D and 2D NMR spectra, C NMR calculations, and electronic circular dichroism (ECD) calculations. Heilaohuacids A and B ( and ) contain a 3,4- ring A and unprecedented migration of Me-18 from C-13 to C-17 or C-14 to C-18.

Triterpenoids from stems of Kadsura heteroclita.

In the present work, we reported the triterpenoids isolated from n-butanol fraction of Kadsura heteroclita which is a Tujia ethnomedicine with trivial name "Xuetong". This effort resulted in the isolation of six unpresented triterpenoids xuetongsu A-F (1-6), along with five known triterpenoids (7-11). The structures of the reported compounds were established on the 1D, and 2D NMR and HRESIMS spectra, along with CD spectroscopic analysis.

HA280 immunoadsorption, an alternative treatment for neuromyelitis optica spectrum disorders?

We report a case of neuromyelitis optica spectrum disorders (NMOSD) with complete loss of vision in the left eye in a patient who was not satisfied with the effect of methylprednisolone therapy, which was improved by HA280 immunoadsorption (IA) therapy. HA280 is a relatively cheaper IA column (made in China) often used in the treatment of rheumatoid immune-related diseases. HA280 can effectively remove inflammatory markers in serum.

Schinortriterpenoids from Tujia ethnomedicine Xuetong-The stems of Kadsura heteroclita.

In the present work, we take advantage of the characteristic NMR signal (δ = 96.0-99.9) for guiding the isolation of schinortriterpenoids (SNTs) from n-butanol fraction of stems of Kadsura heteroclita which is a Tujia ethnomedicine with trivial name "Xuetong".

New Lignans from roots of Kadsura coccinea.

Four new dibenzocyclooctadiene lignans, named heilaohusus A-D (1-4), one new arylnaphthalene lignan named heilaohusu E (5), and seven known analogues (6-12) were isolated from the roots of Kadsura coccinea. Their structures and configurations were elucidated by a combination of HR-ESI-MS, H NMR, C NMR, HSQC, HMBC, NOESY and CD spectra. Among the known compounds, compounds 6 and 8-12 were isolated from this plant for the first time.

Simultaneous Determination of 12 Bioactive Constituents in Bupi Yiqi No. 1 Recipe by Ultrahigh-Performance Liquid Chromatography Tandem Mass Spectrometry.

Background: Bupi Yiqi No. 1 Recipe (BPYQ), a traditional Chinese medicine formula, has been widely used as a treatment of multidrug resistance during chemotherapy in colorectal cancer and for the prevention of gastrointestinal cancer recurrence for decades.

Objective: In this study, a rapid, reliable, and accurate ultrahigh-performance LC (UHPLC) coupled with electrospray ionization (ESI)-tandem MS (MS/MS) method was developed for the simultaneous determination of 12 major bioactive components, including protocatechuic acid, astilbin, rutin, calycosin-7-O-β-D-glucoside, ginsenoside Re, ononin, isoliquiritigenin, calycosin, apigenin, ginsenoside Rb1, formononetin, and glycyrrhizic acid in BPYQ.

Identification of potential diagnostic biomarkers of cerebral infarction using gas chromatography-mass spectrometry and chemometrics.

Cerebral infarction (CI) is one of the most common cerebrovascular diseases and remains a major health problem worldwide. In this study, we evaluated the potential diagnostic biomarkers and important relevant metabolic pathways associated with CI. Metabolomics based on gas chromatography-mass spectrometry coupled with the multivariate pattern recognition technique were used to characterize the potential serum metabolic profiles of CI.

[Intracerebroventricular injection of miR-7 inhibits secondary brain injury induced by intracerebral hemorrhage via EGFR/STAT3 pathway in rats].

Objective To observe the effects of microRNA-7 (miR-7) on intracerebral hemorrhage-induced brain injury in rats and explore the underlying mechanism. Methods Seventy-five SD rats were used to establish intracerebral hemorrhage model through injection of VII collagenase into the pallidum. These rats were then divided into control, miR-7 agomir, agomir control, miR-7 antagomir and antagomir control groups, containing 15 animals in each group.

MicroRNA-134 plasma levels before and after treatment with valproic acid for epilepsy patients.

Background: Temporal lobe epilepsy is the second most common neurological disorders characterized by recurrent spontaneous seizures. MicroRNAs play a vital role in regulating synaptic plasticity, brain development and post-transcriptional expression of proteins. In both animal models of epilepsy and human patients, miR-134, a brain-specific microRNA has recently been identified as a potential regulator of epileptogenesis.

IRF-8 is Involved in Amyloid-β (Aβ)-induced Microglial Activation: a New Implication in Alzheimer's Disease.

It is well known that extracellular deposition of amyloid-β (Aβ) peptide and microglia-mediated neuroinflammation are major hallmarks of Alzheimer's disease (AD). Interferon regulatory factor-8 (IRF-8), an important transcription factor of the IRF family, is highly restricted in microglia in brains. The expression pattern and function of IRF-8 in AD need to be elucidated in order to provide novel therapies for the treatment of AD.

Induction of GADD45α protects M17 neuroblastoma cells against MPP*.

Growth arrest and DNA-damage-inducible protein 45α (GADD45α) is an important member of the family of growth arrest and DNA damage-inducible (GADD) proteins. The expression patterns and possible roles of GADD45α in Parkinson's disease (PD) are so far less understood. In this study, we found that 1-methyl-4-phenylpyridinium (MPP+) treatment up-regulates the expression of GADD45α in both a time-dependent manner and a dose-dependent manner in human dopamine neuroblastoma M17 cells.

Cd72(c) is a modifier gene that regulates Fas(lpr)-induced autoimmune disease.

Although modifier genes are extensively studied in various diseases, little is known about modifier genes that regulate autoimmune diseases. Autoimmune disease caused by the Fas(lpr) mutation depends on the genetic background of mouse strains, suggesting a crucial role of modifier genes. MRL/MpJ-Fas(lpr) (MRL/lpr) and AKR/lpr mice develop severe and mild lupus-like autoimmune disease, respectively, whereas this mutation does not cause disease on C57BL/6 (B6) or C3H background.

Augmented B lymphocyte response to antigen in the absence of antigen-induced B lymphocyte signaling in an IgG-transgenic mouse line.

IgG-containing B cell antigen receptor (IgG-BCR), the BCR mostly expressed on memory B cells, contains a distinct signaling function from IgM-BCR or IgD-BCR expressed on naïve B cells. Because naïve B cells transgenic for IgG exhibit augmented response to antigens similar to memory B cells, the distinct signaling function of IgG-BCR appears to play a role in augmented antibody responses of memory B cells. However, how IgG-BCR signaling augments B cell responses is not yet well understood.
