The Emergent Pelvic Artery Embolization in the Management of Postpartum Hemorrhage: A Systematic Review and Meta-analysis.

Importance: Postpartum hemorrhage (PPH) is an emergent obstetric complication and the leading cause of maternal mortality. Pelvic arterial embolization (PAE) is an effective treatment for intractable PPH. However, a unique protocol has not been accepted in obstetrical practice.

[Congenital ectrodactyly caused by chromosome 10q24.31 duplication and its pathogenetic analysis].

In order to investigate the genetic variations and the clinical manifestations of a range of congenital ectrodactyly family and to summarize the split hand/foot malformation (SHFM) types and their related pathogenic genes, we conducted phenotypic analyses of patient's limbs by physical and X-ray examination. The haplotypes were analyzed by using the extracted genes from peripheral blood on D10S1709, D10S192, D10S597, D10S1693 and D10S587 loci, and the mutation duplication loci were confirmed by Array-CGH detection. The pathogenic factors and inheritance pattern of SHFM were analyzed based on family investigation and gene analysis.

The cardiotoxicity of cetuximab as single therapy in Chinese chemotherapy-refractory metastatic colorectal cancer patients.

The cardiac safety of cetuximab, particularly as single approach, has not been investigated extensively. This trial was designed to evaluate the cardiac safety of cetuximab as salvage monotherapy in Chinese chemotherapy-refractory metastatic colorectal cancer (mCRC) patients.Cetuximab was administrated at an initial dose of 400 mg/mon day 1 (week 1), followed by a maintenance dose of 250 mg/m on day 1 of each 7-day cycle.

Bone marrow-derived mesenchymal stem cells prevent the apoptosis of neuron-like PC12 cells via erythropoietin expression.

It is known that bone marrow-derived mesenchymal stem cells (BM-MSCs) are able to improve neuronal function through secretion of trophic factors in animal models of middle cerebral artery occlusion (MCAo). In this study, we demonstrated that incubation of BM-MSCs protects PC12 cells against apoptosis induced by CoCl(2) via the production of erythropoietin (EPO). Addition of CoCl(2) to BM-MSCs cultures induced the expression of EPO in a time-dependent manner.

Inhibitory kappa-B kinase-β inhibition prevents adaptive left ventricular hypertrophy.

Background: Most cardiovascular studies have implicated the central transcription factor nuclear factor kappa-B (NF-κB) as contributing to the detrimental effects of cardiac injury. This ostensibly negative view of NF-κB competes with its important role in the normal host inflammatory and immune response. Pressure overload, left ventricular hypertrophy (LVH), and heart failure represent a spectrum of disease that has both adaptive and maladaptive components.

Direct toxic effects of aqueous extract of cigarette smoke on cardiac myocytes at clinically relevant concentrations.

Aims: Our goal was to determine if clinically relevant concentrations of aqueous extract of cigarette smoke (CSE) have direct deleterious effects on ventricular myocytes during simulated ischemia, and to investigate the mechanisms involved.

Methods: CSE was prepared with a smoking chamber. Ischemia was simulated by metabolic inhibition (MI) with cyanide (CN) and 0 glucose.

CRYAB and HSPB2 deficiency increases myocyte mitochondrial permeability transition and mitochondrial calcium uptake.

Double knockout (DKO) of the small heat shock proteins CRYAB and HSPB2 increases necrosis and apoptosis induced by ischemia/reperfusion (I/R) in vitro, but the mechanisms involved are unknown. We examined [Ca2+]i during metabolic inhibition (MI) changes in [Ca2+]m induced by exposure to elevated [Ca2+]i, and whether mitochondria in isolated DKO ventricular myocytes (VM) are more susceptible than wild type (WT) to induction of the mitochondrial permeability transition (MPT). The rise in [Ca2+]i in DKO myocytes during metabolic inhibition (MI) was less than in WT, and ouabain caused a greater increase in [Ca2+]m in DKO than in WT.

A molecular variant of angiotensinogen is associated with idiopathic intrauterine growth restriction.

Objective: Intrauterine growth restriction has been associated with failed maternal physiologic changes such as abnormal spiral artery remodeling and reduced maternal blood volume. A polymorphism of angiotensinogen Thr235 has been considered a risk factor for preeclampsia. We genotyped maternal and fetal deoxyribonucleic acid (DNA) for angiotensinogen Thr235 to estimate whether the polymorphism is also a risk factor for intrauterine growth restriction.
