Risk factors of central catheter bloodstream infections in intensive care units: A systematic review and meta-analysis.

Background: Central catheter bloodstream infections (CRBSI) is a major cause of healthcare-associated infections. However, few factors are generally accepted and some studies have conflicting finding about some factors, possibly caused by limitation associated with an individual study. This study was to identify risk factors for CRBSI in intensive care units.

Fabrication and Optimization of the Thermo-Sensitive Hydrogel Carboxymethyl Cellulose/Poly(N-isopropylacrylamide-co-acrylic acid) for U(VI) Removal from Aqueous Solution.

In this work, the thermo-sensitive materials N-isopropylacrylamide (NIPAM) and acrylic acid (AA) were crosslinked with carboxymethyl cellulose (CMC) (CMC/P (NIPAM-co-AA)) via a free radical polymerization method for the removal of U(VI) from aqueous solution. The L16 (4) orthogonal experiments were designed for the optimization of the synthesis condition. The chemical structures of the crosslinking hydrogel were confirmed by FTIR spectroscopy.

[Volume of 4% neutral buffered formaldehyde affects the results of gene detected by fluorescence hybridization in primary invasive breast cancer].

Objective: To investigate the effects of the volume of 4% neutral phosphate buffered formalin fixative solution on the detection of human epidermal growth factor receptor 2 () gene by fluorescence hybridization (FISH) in primary invasive breast cancer.

Methods: Tissue samples were collected from 109 patients with primary invasive breast cancer admitted in Zhongshan Boai Hospital from June 2014 to October 2016. The ratios of 4% phosphate buffered formalin fixative solution to sample volume samples were 3:1, 6:1, 9:1, 10:1, 15:1, 20:1 or 25:1 (groups A, B, C, D, E, F and G), respectively.

[Application of Van-Clear and xylene in the detection of cervical hTERC gene by fluorescence in situ hybridization].

Objective: To observe the effect of Van-Clear on vamplification of human telomerase RNA component (hTERC) gene in cervical tissues by fluorescence in situ hybridization, and to determine the potential for Van-Clear to replace xylene.


Methods: A total of 278 specimens of cervix uteri were collected from inpatients of Department of Gynaecology in Boai Hospital of Zhongshan from January to February, 2015, with 81 cases of normal specimens, 68 cases of cervical intraepithelial neoplasia (CIN) I, 57cases of CIN2, 42 cases of CIN3 and 30 cases of cervical invasive cancer. Double samples were collected from the same region.
