Association of hemoglobin with arterial stiffness evaluated by carotid-femoral pulse wave velocity among Chinese adults.

Objective: Increased hemoglobin (Hb) levels are known to be associated with increased cardiovascular events and mortalities. Therefore, we assumed that high Hb levels were associated with arterial stiffness. Pulse wave velocity (PWV) is a simple and noninvasive method for measuring arterial stiffness to assess cardiovascular disease in general populations.

Anesthetic constituents of Zanthoxylum bungeanum Maxim.: A pharmacokinetic study.

A sensitive and selective ultra high performance liquid chromatography with tandem mass spectrometry method was established and validated for the simultaneous determination of hydroxy-α-sanshool, hydroxy-β-sanshool, and hydroxy-γ-sanshool in rat plasma after the subcutaneous and intravenous administration of an extract of the pericarp of Zanthoxylum bungeanum Maxim. Piperine was used as the internal standard. The analytes were extracted from rat plasma by liquid-liquid extraction with ethyl acetate and separated on a Thermo Hypersil GOLD C18 column (2.

Association between microalbuminuria and subclinical atherosclerosis evaluated by carotid artery intima-media in elderly patients with normal renal function.

Background: Moderate to severe renal insufficiency and albuminuria have been shown to be independent risk factors for atherosclerosis. However, little is known about the direct association between subclinical atherosclerosis evaluated by carotid artery intima-media thickness (IMT) and microalbuminuria in elderly patients with normal renal function.

Methods: Subjects were 272 elderly patients (age  ≥ 60 years) with normoalbuminuria (n = 238) and microalbuminuria (n = 34).

[Clinical significance of toll-like receptor 4 expression on the surface of peripheral blood mononuclear cells in uremic patients].

Objective: To explore the clinical significance of toll-like receptor 4 expression on the surface of peripheral blood mononuclear cells (PBMC) in uremic patients and observe the effect of ultrapure dialysate on the PBMC expression of TLR4 in these patients.

Methods: Eighty patients on maintenance dialysis were randomly divided into two groups: conventional dialysate group (CD, n=40), ultrapure dialysate group (UPD, n=40) and 40 uremic patients without dialysis in NHD group. The blood cells from all patients and 40 healthy controls were stained with FITC labeling anti-TLR4 monoclonal antibodies.

[Specific promoters used in plant gene engineering].

The choice of specific promoters used within a transgene construct is a vital strategy to achieve the transgene regulation in the temporal, spatial and measurable manner. The strategy has been widely used in diverse aspects of plant gene engineering, such as quality improvement, resistance breeding and bioreactor. In this paper, we describe the structure feature, classification and research method of the specific promoter and its application progresses in plant gene engineering.
