Nurses' turnover intention in secondary hospitals in China: A structural equation modelling approach.

Aim: To identify the factors affecting nurses' turnover intention.

Background: The shortage of nurses has been a great challenge worldwide, and nurses' turnover may exacerbate the situation.

Methods: A cross-sectional study was conducted among nurses in six secondary hospitals in China.

[DNA hypomethylation in villi of patients with unexplained recurrent spontaneous abortion and its mechanism].

Objective To explore the genome-wide DNA methylation level and the expression of DNA methylation-related enzymes in the villi tissue of patients with unexplained recurrent spontaneous abortion (URSA). Methods The villi samples were obtained from thirty-one URSA patients (URSA group) and thirty pregnancy women who underwent induced abortion (control group). Total DNA methylation was determined by ELISA.

Decreased expression of CD200 and CD200R1 by human decidual tissues in spontaneous early abortion.

To examine the cellular distribution and the expression of CD200 and its receptor 1 (CD200R1) in human deciduas in first-trimester pregnant women with spontaneous early abortion (SEA) and normal pregnancy, and to explore their role in the etiology of SEA. Thirty-five women at 6-10-week gestation with SA and 30 women of similar gestational age with a healthy pregnancy were recruited. Expression of CD200 and CD200R1 in the deciduas was determined using immunohistochemistry, confocal laser scanning microscope, Western blot, and real-time PCR (RT-PCR).

Fabrication of Large-Scale Microlens Arrays Based on Screen Printing for Integral Imaging 3D Display.

The low-cost large-scale fabrication of microlens arrays (MLAs) with precise alignment, great uniformity of focusing, and good converging performance are of great importance for integral imaging 3D display. In this work, a simple and effective method for large-scale polymer microlens arrays using screen printing has been successfully presented. The results show that the MLAs possess high-quality surface morphology and excellent optical performances.

Structural, optical, and improved field-emission properties of tetrapod-shaped Sn-doped ZnO nanostructures synthesized via thermal evaporation.

High-quality tetrapod-shaped Sn-doped ZnO (T-SZO) nanostructures have been successfully synthesized via the thermal evaporation of mixed Zn and Sn powder. The effects of the Sn dopant on the morphology, microstructure, optical, and field-emission (FE) properties of T-SZO were investigated. It was found that the growth direction of the legs of T-SZO is parallel to the [0001] crystal c-axis direction and that the incorporation of Sn in the ZnO matrix increases the aspect ratio of the tetrapods, leads to blue shift in the UV region, and considerably improves the FE performance.

[Expression and significance of IL-10 in human chorionic villi of recurrent spontaneous abortion].

Aim: To investigate the correlation between interleukin-10(IL-10) and recurrent spontaneous abortion as well as the significance of them through researching the comparison of histological localization of IL-10, expression comparison of IL-10 mRNA in human chorionic villi of pregnant women with recurrent spontaneous abortion and normal abortion.

Methods: To detect expression comparison of IL-10 mRNA and histological localization of IL-10 in human chorionic villi of 35 pregnant women with recurrent spontaneous abortion(experimental group) and 35 normal abortion women(control group) by reverse transcription-polymerase chain reaction and immunohistochemistry. To analysis expression of IL-10 in serum of the two groups by ELISA.

[Expression of laminin and laminin receptor in gestational trophoblastic tumor and its significance].

Objective: This study was conducted to detect the expression of laminin (LN) and laminin receptor (LN-R) in the specimens of hydatidiform mole (HM), invasive mole (IM) and choriocarcinoma(CC), respectively.

Methods: The immunohistological staining method was used.

Results: It was found that the level of the laminin expression was higher in the specimens of choriocarcinoma at more advanced stage.
