Incidence and risk factors of depression in patients with metabolic syndrome.

Background: Many studies have explored the relationship between depression and metabolic syndrome (MetS), especially in older people. China has entered an aging society. However, there are still few studies on the elderly in Chinese communities.

Association between platelet distribution width and poor outcome of acute ischemic stroke after intravenous thrombolysis.

Purpose: The platelet distribution width (PDW) reflects the status of platelet activity and may be useful for early predictions of the clinical outcome of stroke patients. The purpose of the study was to determine the associations between PDW and clinical outcomes after intravenous thrombolysis in stroke patients.

Patients And Methods: Acute ischemic stroke patients who received intravenous treatment with recombinant tissue-type plasminogen activator were selected for inclusion in the retrospective cohort of this study.

Impaired visual, working, and verbal memory in first-episode, drug-naive patients with major depressive disorder in a Chinese population.

Cognitive impairment has been observed in patients with major depressive disorder (MDD). However, it remains unclear whether the deficits in specific cognitive domains are present in first-episode, drug-naïve patients or medicated patients. In the present study, using the CogState battery (CSB) Chinese language version, we evaluated the visual, working, and verbal memory in first-episode drug-naive patients and medicated patients with MDD in a Chinese population.

De Ritis ratio (AST/ALT) as an independent predictor of poor outcome in patients with acute ischemic stroke.

Purpose: The aspartate transaminase/alanine transaminase ratio (De Ritis ratio, AAR) was reported to be associated with patients' prognosis in certain diseases recently. The objective of the current study was to determine the association between the AAR at admission and poor outcome at 3 months in acute ischemic stroke (AIS) patients.

Patients And Methods: This retrospective cohort study included patients who experienced their first-ever AIS between June 2015 and March 2016.

Effect of Hypokalemia on Functional Outcome at 3 Months Post-Stroke Among First-Ever Acute Ischemic Stroke Patients.

BACKGROUND Hypokalemia has been confirmed to be a predictor of adverse cardiovascular and renal outcomes. There is a paucity of studies focusing on the potential connection between the serum K+ level and the outcome after acute ischemic stroke (AIS). This study investigated whether hypokalemia in the acute stroke stage contributes to worse functional outcome in AIS patients.

Increased methylation of glucocorticoid receptor gene promoter 1 in peripheral blood of patients with generalized anxiety disorder.

Previous findings on the dysfunction of hypothalamic-pituitary-adrenal (HPA) axis in generalized anxiety disorder (GAD) are controversial, and the molecular mechanisms underlying such dysfunction remain unclear. We analyzed the methylation status of the NR3C1 1 promoter and the expression of glucocorticoid receptor-α isoform (GRα) in peripheral blood mononuclear cells (PMBCs), the basal cortisol level in serum, and a functional neuroendocrine marker for GR sensitivity in the PMBCs in 64 patients with current GAD and 85 healthy controls. We found that patients with GAD had significantly elevated levels of morning basal serum cortisol (P < 0.

The effect of reintubation on ventilator-associated pneumonia and mortality among mechanically ventilated patients with intubation: A systematic review and meta-analysis.

Objectives: This meta-analysis summarized the risks that reintubation impose on ventilator-associated pneumonia (VAP) and mortality.

Background: Extubation failure increases the probability of poor clinical outcomes pertaining to mechanical ventilation.

Methods: Literature published during a 15-year period was retrieved from PubMed, Web of Knowledge databases, the Embase (Excerpa Medica database), and the Cochrane Library.

Intranasal Delivery of Recombinant AAV Containing BDNF Fused with HA2TAT: a Potential Promising Therapy Strategy for Major Depressive Disorder.

Depression is a disturbing psychiatric disease with unsatisfied therapy. Not all patients are sensitive to anti-depressants currently in use, side-effects are unavoidable during therapy, and the cases with effectiveness are always accompanied with delayed onset of clinical efficacy. Delivering brain-derived neurotrophic factor (BDNF) to brain seems to be a promising therapy.

Intranasal Delivery of Recombinant NT4-NAP/AAV Exerts Potential Antidepressant Effect.

The present study was designed to construct a recombinant adeno-associated virus (rAAV) which can express NAP in the brain and examine whether this virus can produce antidepressant effects on C57 BL/6 mice that had been subjected to open field test and forced swimming test, via nose-to-brain pathway. When the recombinant plasmid pGEM-T Easy/NT4-NAP was digested by EcoRI, 297 bp fragments can be obtained and NT4-NAP sequence was consistent with the designed sequence confirmed by DNA sequencing. When the recombinant plasmid pSSCMV/NT4-NAP was digested by EcoRI, 297 bp fragments is visible.

Genetic polymorphisms of CYP1A1 and risk of leukemia: a meta-analysis.

The associations between CYP1A1 polymorphisms and risk of leukemia have been studied extensively, but the results have been inconsistent. Therefore, in this study, we performed a meta-analysis to clarify associations of three CYP1A1 polymorphisms (T3801C, A2455G, and C4887A) with the risks of acute lymphoblastic leukemia (ALL), acute myeloid leukemia (AML), and chronic myeloid leukemia (CML). Medline, EMBASE, and China National Knowledge Infrastructure databases were searched to collect relevant studies published up to April 20, 2015.

A common genetic variation in CEBPE and acute lymphoblastic leukemia: a meta-analysis of the available evidence.

Acute lymphoblastic leukemia (ALL) has been studied intensively for decades, but the details of its etiology and underlying mechanisms have yet to be fully elucidated. It is now generally acknowledged that genetic factors contribute greatly to the development of this disease. The gene encoding CCAAT/enhancer-binding protein ε (CEBPE) is involved in the development of leukemia, and in particular the rs2239633 single nucleotide polymorphism (SNP) of CEBPE.

HINT1 is involved in the behavioral abnormalities induced by social isolation rearing.

Social isolation (SI) rearing has been demonstrated to induce behavioral abnormalities like anxiety, impulsivity, aggression, and learning and memory deficits which are relevant to core symptoms in patients with some certain neuropsychiatric disorders. But the underlying pathophysiological mechanisms remain unclear. Recent studies have revealed HINT1 has close relation with diverse neuropsychiatric diseases.

Association Between MKP-1, BDNF, and Gonadal Hormones with Depression on Perimenopausal Women.

Background: Studies suggest that brain-derived neurotrophic factor (BDNF) exerts effects on the neuronal function of hippocampal neurons and increases hippocampal mitogen-activated protein kinase phosphatase-1 (MKP-1) expression, which causes depressive behaviors in rat or mouse. Here we focus on the change of serum MKP-1, BDNF, testosterone (T), and estradiol (E2) levels, in order to test the hypothesis that dysregulation of MKP-1, BDNF, T, and E2 are associated with depression in perimenopausal women.

Methods: Women with depression, after meeting criteria in the International Statistical Classification of Diseases and Related Health Problems, 10th Revision, for mental and behaviural disorders and the 17-item Hamilton Depression Rating Scale (HDRS), were included in the study.

Zirconium oxide ceramic foam: a promising supporting biomaterial for massive production of glial cell line-derived neurotrophic factor.

This study investigated the potential application of a zirconium oxide (ZrO2) ceramic foam culturing system to the production of glial cell line-derived neurotrophic factor (GDNF). Three sets of ZrO2 ceramic foams with different pore densities of 10, 20, and 30 pores per linear inch (PPI) were prepared to support a 3D culturing system. After primary astrocytes were cultured in these systems, production yields of GDNF were evaluated.

Targeting of NMDA receptors in the treatment of major depression.

Major depressive disorder (MDD) is a common, recurrent mental illness that affects millions of people worldwide. Accumulating evidence suggests that the N-methyl-D-aspartate (NMDA) receptor, a subtype of glutamate receptors, plays an important role in the neurobiology and treatment of this disease. Currently, the non-competitive NMDA receptor antagonist ketamine is considered as one of the most attractive candidate drugs in therapy of treatment-resistant depression.

Association of the GDNF gene with depression and heroin dependence, but not schizophrenia, in a Chinese population.

The association of seven GDNF tag SNPs with depression, heroin dependence (HD) and schizophrenia was evaluated in Chinese. An increased risk of HD and depression was associated with rs2910709 T/T genotype and rs884344 C allele, respectively, suggesting GDNF is a novel susceptibility gene for depression and HD.

Long-lasting antidepressant action of ketamine, but not glycogen synthase kinase-3 inhibitor SB216763, in the chronic mild stress model of mice.

Background: Clinical studies demonstrate that the N-methyl-D-aspartate (NMDA) receptor antagonist, ketamine, induces rapid antidepressant effects in patients with refractive major depressive disorder and bipolar depression. This rapid onset of action makes ketamine a highly attractive drug for patients, particularly those who do not typically respond to therapy. A recent study suggested that glycogen synthase kinase (GSK)-3 may underlie the rapid antidepressant action of ketamine, although the precise mechanisms are unclear.

Prevalence of PTSD and depression among junior middle school students in a rural town far from the epicenter of the Wenchuan earthquake in China.

Context: On May 12(th) 2008, a devastating earthquake measuring 8.0 on the Richter scale, struck Wenchuan county and surrounding areas in China. The prevalence of mental illness among children and adolescents in a rural town far from the earthquake epicenter is unknown.

Screening of the Salmonella paratyphi A CMCC 50973 strain outer membrane proteins for the identification of potential vaccine targets.

Outer membrane protein antigens usually have strong immunogenicities, closely interact with the immune system and play a significant role in the development of new vaccines. The outer membrane proteins of Salmonella paratyphi A (S. paratyphi A) were screened for immunogenicity and immunoprotection for potential vaccine targets.

Social isolation-induced aggression potentiates anxiety and depressive-like behavior in male mice subjected to unpredictable chronic mild stress.

Background: Accumulating epidemiological evidence shows that life event stressors are major vulnerability factors for psychiatric diseases such as major depression. It is also well known that social isolation in male mice results in aggressive behavior. However, it is not known how social isolation-induced aggression affects anxiety and depressive-like behavior in isolated male mice subjected to unpredictable chronic mild stress (CMS), an animal model of depression.

Differences in hypothyroidism between lithium-free and -treated patients with bipolar disorders.

The majority of the previous studies of thyroid abnormalities in bipolar patients was conducted in populations containing various proportions of lithium-treated subjects. In the present study, we sought to determine whether there exist differences in hypothyroid profile between lithium-free and -treated bipolar patients. Bipolar patients never treated with lithium and carbamazepine (n=78) and those currently in lithium therapy (n=53) were included in this study.

Adjunctive herbal medicine with carbamazepine for bipolar disorders: A double-blind, randomized, placebo-controlled study.

Chinese herbal medicines possess the therapeutic potential for mood disorders. This double-blind, randomized, placebo-controlled study was designed to evaluate the efficacy and side effects of the herbal medicine called Free and Easy Wanderer Plus (FEWP) as an adjunct to carbamazepine (CBZ) in patients with bipolar disorders. One hundred and twenty-four bipolar depressed and 111 manic patients were randomized to treatment with CBZ alone, CBZ plus FEWP, or equivalent placebo for 12 weeks.
