Silicon reduces lead accumulation in Moso bamboo via immobilization and suppression of metal cation transporter genes in roots.

Lead (Pb) is a hazardous element that affects the growth and development of plants, while silicon (Si) is a beneficial element for alleviating the stress caused by heavy metals, including Pb. However, the mechanisms of Si reduce Pb accumulation in Moso bamboo remain unclear. In this study, physiological assessments and transcriptome analyses were conducted to investigate the interaction between Si and Pb.

Screening and evaluation of bamboo shoots: Comparing the content of trace elements from 100 species.

Hundreds of bamboo shoots have been reported to be edible, but the accumulation of trace elements and hazardous elements in bamboo shoots is poorly understood. Here, 100 bamboo species have been evaluated by screening elements including B, Fe, Mn, Cu, Zn, Cd, Pb and As in bamboo shoots using different assessment systems. Bamboo shoots displayed different morphological characteristics, and large differences were found in the concentration of elements.

Identification of an acute myeloid leukaemia associated noncoding somatic mutation at 3' end of HOXA cluster.

Noncoding somatic mutations have been demonstrated to play important role in tumourigenesis. Here we show that there exists an acute myeloid leukaemia associated noncoding somatic mutation at 3' terminal of conserved cluster. The mutation was identified in the bone marrow blasts but not peripheral blood mononuclear cells or buccal cells of two M3 (acute promyelocytic leukaemia, APL) type patients from 45 acute myeloid leukaemia patients.

[Effects of a Traditinal Chinese Medicine Compound Regimen on Differentiation and Proliferation of Acute Myeloid Leukemia Cell Lines].

Objective: To study the effect of traditional chinese medicine (TCM) compound on myeloid leukemia cells and to explore its anti-leukemic mechanism.

Methods: Myeloid leukemia cell lines were cultured in vitro and treated with TCM compound. The proliferation of the leukemia cells was measured by CCK8 method.

Smoking and major depressive disorder in Chinese women.

Objective: To investigate the risk factors that contribute to smoking in female patients with major depressive disorder (MDD) and the clinical features in depressed smokers.

Methods: We examined the smoking status and clinical features in 6120 Han Chinese women with MDD (DSM-IV) between 30 and 60 years of age across China. Logistic regression was used to determine the association between clinical features of MDD and smoking status and between risk factors for MDD and smoking status.

Associations of educational attainment, occupation, social class and major depressive disorder among Han Chinese women.

Background: The prevalence of major depressive disorder (MDD) is higher in those with low levels of educational attainment, the unemployed and those with low social status. However the extent to which these factors cause MDD is unclear. Most of the available data comes from studies in developed countries, and these findings may not extrapolate to developing countries.

Childhood sexual abuse and the development of recurrent major depression in Chinese women.

Background: Our prior study in Han Chinese women has shown that women with a history of childhood sexual abuse (CSA) are at increased risk for developing major depression (MD). Would this relationship be found in our whole data set?

Method: Three levels of CSA (non-genital, genital, and intercourse) were assessed by self-report in two groups of Han Chinese women: 6017 clinically ascertained with recurrent MD and 5983 matched controls. Diagnostic and other risk factor information was assessed at personal interview.

[Effects of fertilization on soil CO2 flux in Castanea mollissima stand].

In June 2011-June 2012, a fertilization experiment was conducted in a typical Castanea mollissima stand in Lin' an of Zhejiang Province, East China to study the effects of inorganic and organic fertilization on the soil CO2 flux and the relationships between the soil CO2 flux and environmental factors. Four treatments were installed, i. e.

Clinical features of patients with dysthymia in a large cohort of Han Chinese women with recurrent major depression.

Background: Dysthymia is a form of chronic mild depression that has a complex relationship with major depressive disorder (MDD). Here we investigate the role of environmental risk factors, including stressful life events and parenting style, in patients with both MDD and dysthymia. We ask whether these risk factors act in the same way in MDD with and without dysthymia.

Solvothermal synthesis and characterization of thioindate-thioantimonates with transition-metal complexes: the first examples of the incorporation of transition metal ions into In-S-Sb frameworks.

Three new thioindate-thioantimonates [Ni(en)(3)][In(2)Sb(2)S(7)] (1, en = ethylenediamine), [(Ni(en)(3))](3)(en)[In(6)Sb(6)S(21)] (2), and [Co(tren)InSbS(4)] (3, tren = tris(2-aminoethyl)amine) have been solvothermally synthesized and structurally characterized. Compound 1 contains dimeric [In(2)S(7)] units built of two tetrahedral [InS(4)] units sharing one corner and [SbS(3)] trigonal-pyramids, which are interconnected to form a puckered [In(2)Sb(2)S(7)](n)(2n-) layer with 4-, 5- and 6-heterorings. [Ni(en)(3)](2+) complex cations as structure-directing and charge-balancing agents are located at the interlayer spaces.

[Comparative observation on efficacy of jieyu pill and maprotiline in treating depression].

Objective: To investigate the clinical efficacy, adverse reaction and safety of Jieyu pill (JYP) in treating depression.

Methods: The randomized controlled trial was conducted in 28 patients in the treated group and 29 patients in the control group treated with maprotiline (Map). The efficacy of treatment was evaluated before treatment and 14, 28 and 42 days after treatment, with Hamilton depression rating scale (HAMD), self-rating scale for depression (SDS), self-rating scale for anxiety (SAS) and clinical global impression (CGI), the adverse reaction was assessed by Asberg Rating Scale (ARS).
