Treatment of acute intracerebral haemorrhage with a Chinese herbal formula (Shengdi Dahuang Decoction): a multicentre, double-blind, randomised, placebo-controlled trial.

Importance: Per preliminary studies, Shengdi Dahuang Decoction (SDD) is potentially effective for acute intracerebral haemorrhage (ICH); however, its effectiveness has not been rigorously assessed in extensive randomised clinical trials.

Objective: To evaluate whether SDD can improve 90-day functional outcomes in patients with ICH.

Design: Randomised, double-blind, placebo-controlled clinical trial included patients with acute ICH within 4 hours of symptom onset at five hospitals in Shanghai, China.

A Transient Increase in Cardiomyocyte Protein O-GlcNAcylation Enhances Susceptibility to Pressure Overload-Induced Cardiac Remodeling.

Background: The observation that diabetic patients always under tight-glycemic control consistently show better cardiovascular disease outcomes compared to patients who transition to tight-glycemic control after prior conventional glycemic control lead to the concept of metabolic memory. Mechanisms such as epigenetics possibly mediate the lasting metabolic memory effects, our understanding of the underlying mechanisms remains limited. Increased cardiac protein posttranslational O-linked β-N-acetylglucosamine (O-GlcNAc) modification is implicated in cardiac remodeling observed in diabetes, and our previous work shows chronically elevated cardiomyocyte O-GlcNAc causes adverse cardiac changes.

Clinical characteristics of adnexal torsion and role of ovarian sparing surgery: a clinical retrospective analysis.

Sustained Increases in Cardiomyocyte Protein -Linked β-N-Acetylglucosamine Levels Lead to Cardiac Hypertrophy and Reduced Mitochondrial Function Without Systolic Contractile Impairment.

Background Lifestyle and metabolic diseases influence the severity and pathogenesis of cardiovascular disease through numerous mechanisms, including regulation via posttranslational modifications. A specific posttranslational modification, the addition of -linked β- acetylglucosamine (-GlcNAcylation), has been implicated in molecular mechanisms of both physiological and pathologic adaptations. The current study aimed to test the hypothesis that in cardiomyocytes, sustained protein -GlcNAcylation contributes to cardiac adaptations, and its progression to pathophysiology.

Clinical Characteristics of Acute Lower Extremity Ischemia Due to Left Atrial Myxoma: A Rare Case Report with Review of Literature.

Emboli caused by cardiac myxomas mostly occur in the cardiovascular or cerebrovascular systems and rarely in the lower extremity vasculature. We introduce the rare case of a patient with left atrial myxoma (LAM) whose right lower extremity (RLE) suffered from acute ischemia due to tumor fragments, along with a review of the relevant literature, and highlight the clinical characteristics of LAM. An 81-year-old female presented with acute ischemia of RLE.

Cardiomyocyte ZKSCAN3 regulates remodeling following pressure-overload.

Autophagy is important for protein and organelle quality control. Growing evidence demonstrates that autophagy is tightly controlled by transcriptional mechanisms, including repression by zinc finger containing KRAB and SCAN domains 3 (ZKSCAN3). We hypothesize that cardiomyocyte-specific ZKSCAN3 knockout (Z3K) disrupts autophagy activation and repression balance and exacerbates cardiac pressure-overload-induced remodeling following transverse aortic constriction (TAC).

Increased Glucose Availability Attenuates Myocardial Ketone Body Utilization.

Background Perturbations in myocardial substrate utilization have been proposed to contribute to the pathogenesis of cardiac dysfunction in diabetic subjects. The failing heart in nondiabetics tends to decrease reliance on fatty acid and glucose oxidation, and increases reliance on ketone body oxidation. In contrast, little is known regarding the mechanisms mediating this shift among all 3 substrates in diabetes mellitus.

Relationship between Amphipathic β Structures in the β Domain of Apolipoprotein B and the Properties of the Secreted Lipoprotein Particles in McA-RH7777 Cells.

Our previous studies demonstrated that the first 1000 amino acid residues (the βα domain) of human apolipoprotein (apo) B-100, termed apoB:1000, are required for the initiation of lipoprotein assembly and the formation of a monodisperse stable phospholipid (PL)-rich particle. The objectives of this study were (a) to assess the effects on the properties of apoB truncates undergoing sequential inclusion of the amphipathic β strands in the 700 N-terminal residues of the β domain of apoB-100 and (b) to identify the subdomain in the β domain that is required for the formation of a microsomal triglyceride transfer protein (MTP)-dependent triacylglycerol (TAG)-rich apoB-containing particle. Characterization of particles secreted by stable transformants of McA-RH7777 cells demonstrated the following.

Phospholipid transfer protein plays a major role in the initiation of apolipoprotein B-containing lipoprotein assembly in mouse primary hepatocytes.

In this study, we tested the hypothesis that phospholipid transfer protein (PLTP) is a plausible mediator of phospholipid (PL) transfer to the N-terminal 1000 residues of apoB (apoB:1000) leading to the initiation of apoB-containing lipoprotein assembly. To this end, primary hepatocytes from wild type (WT) and PLTP knock-out (KO) mice were transduced with adenovirus-apoB:1000 with or without co-transduction with adenovirus-PLTP, and the assembly and secretion of apoB:1000-containing lipoproteins were assessed. PLTP deficiency resulted in a 65 and 72% reduction in the protein and lipid content, respectively, of secreted apoB:1000-containing lipoproteins.

Intestinal T-cell lymphomas: a retrospective analysis of 68 cases in China.

Aim: To investigate the clinical features, diagnosis, treatment and prognosis of intestinal T-cell lymphomas (ITCL) by retrospective analysis.

Methods: Sixty-eight patients who were diagnosed with ITCL in case reports in the Chinese literature were compiled and reviewed. Age, gender, CD56 expression, surgical management, multifocal nature, perforation and cyclophosphamide chemotherapy were analyzed as the prognostic factors.

Enhancement of antitumor immunity in lung cancer by targeting myeloid-derived suppressor cell pathways.

Chemoresistance due to heterogeneity of the tumor microenvironment (TME) hampers the long-term efficacy of first-line therapies for lung cancer. Current combination therapies for lung cancer provide only modest improvement in survival, implicating necessity for novel approaches that suppress malignant growth and stimulate long-term antitumor immunity. Oxidative stress in the TME promotes immunosuppression by tumor-infiltrating myeloid-derived suppressor cells (MDSC), which inhibit host protective antitumor immunity.

Apolipoprotein B-containing lipoprotein assembly in microsomal triglyceride transfer protein-deficient McA-RH7777 cells.

Microsomal triglyceride transfer protein (MTP) is required for the assembly and secretion of apolipoprotein (apo) B-containing lipoproteins. Previously, we demonstrated that the N-terminal 1,000 residues of apoB (apoB:1000) are necessary for the initiation of apoB-containing lipoprotein assembly in rat hepatoma McA-RH7777 cells and that these particles are phospholipid (PL) rich. To determine if the PL transfer activity of MTP is sufficient for the assembly and secretion of primordial apoB:1000-containing lipoproteins, we employed microRNA-based short hairpin RNAs (miR-shRNAs) to silence Mttp gene expression in parental and apoB:1000-expressing McA-RH7777 cells.

Development of Spontaneous Hygromycin B Resistance in Monilinia fructicola and Its Impact on Growth Rate, Morphology, Susceptibility to Demethylation Inhibitor Fungicides, and Sporulation.

ABSTRACT Agrobacterium tumefaciens-mediated transformation with plasmids carrying the hygromycin B resistance gene hph frequently is being used for inserting genes into fungal spores and mycelial cells and for conducting insertional mutagenesis to identify genes connected to a particular phenotype. In this article, we report that stable hygromycin B resistance can develop spontaneously in germinating conidia from Monilinia fructicola and that the mutants exhibit altered phenotypes. One spontaneously developing hygromycin B-resistant colony developed per 2.

Charged amino acid residues 997-1000 of human apolipoprotein B100 are critical for the initiation of lipoprotein assembly and the formation of a stable lipidated primordial particle in McA-RH7777 cells.

We previously demonstrated that a portion, or perhaps all, of the residues between 931 and 1000 of apolipoprotein (apo) B100 are required for the initiation of apoB-containing particle assembly. Based on our structural model of the first 1000 residues of apoB (designated as apoB:1000), we hypothesized that this domain folds into a three-sided lipovitellin-like "lipid pocket" via a hairpin-bridge mechanism. We proposed that salt bridges are formed between four tandem charged residues 717-720 in the turn of the hairpin bridge and four tandem complementary residues 997-1000 located at the C-terminal end of the model.

Microsomal triglyceride transfer protein activity is not required for the initiation of apolipoprotein B-containing lipoprotein assembly in McA-RH7777 cells.

We previously demonstrated that the N-terminal 1000 amino acid residues of human apolipoprotein (apo) B (designated apoB:1000) are competent to fold into a three-sided lipovitellin-like lipid binding cavity to form the apoB "lipid pocket" without a structural requirement for microsomal triglyceride transfer protein (MTP). Our results established that this primordial apoB-containing particle is phospholipid-rich (Manchekar, M., Richardson, P.
