Effects of postoperative glucocorticoids on mitigation of organ dysfunction in patients with type A aortic dissection: a randomized controlled trial.

Objectives: This study aims to evaluate the organ-protective efficacy of postoperative glucocorticoid in patients with type A aortic dissection.

Methods: Postoperative type A aortic dissection patients were randomly allocated to receive either postoperative glucocorticoid or standard-of-care treatment. Intravenous methylprednisolone was administered for 3 days.

Nomogram for prediction of peritoneal metastasis risk in colorectal cancer.

Objective: Peritoneal metastasis is difficult to diagnose using traditional imaging techniques. The main aim of the current study was to develop and validate a nomogram for effectively predicting the risk of peritoneal metastasis in colorectal cancer (PMCC).

Methods: A retrospective case-control study was conducted using clinical data from 1284 patients with colorectal cancer who underwent surgery at the First Affiliated Hospital of Guangxi Medical University from January 2010 to December 2015.

The effects of virtual reality technology on reducing pain in wound care: A meta-analysis and systematic review.

Virtual reality (VR) technology has been widely used in clinical nursing care in recent years. We aimed to systematically evaluate the effect and safety of VR technology on pain control in wound care, to provide evidence and support for clinical wound care. We searched PubMed, EMBASE, Cochrane Library, Web of Science, CINAHL, China Biomedical Literature Database, China National Knowledge Infrastructure (CNKI), Wanfang Data Knowledge Service Platform, and Chinese Science and Technology Journal databases for randomised controlled trials (RCTs) on the application of VR technology in wound care up to December 20, 2021.

[Effects of simvastatin on pulmonary fibrosis and endothelial - mesenchymal transition in the pulmonary fibrosis tissue of rats].

To investigate the effects of simvastatin (SIM) on pulmonary fibrosis and the expression of VE-cadherin(VE-cad),vimentin(VIM) and alpha-smooth muscle actin(α-SMA)in the pulmonary fibrosis tissue of rats. Sixty healthy male SD rats were randomly divided into control group(group A), bleomycin group(group B), 5 mg SIM group (group C) and 10 mg SIM group (group D),15 rats in each group. The model of rat pulmonary fibrosis was established by itraperitoneal injection of bleomycin(5 mg/kg).

Modular composite building in urgent emergency engineering projects: A case study of accelerated design and construction of to COVID-19 pandemic.

Wuhan Leishenshan/Leishenshan ("Leishenshan" for short) hospital is a makeshift emergency hospital for treating patients diagnosed with the novel coronavirus-infected pneumonia (NCIP). Engineering construction uses modular composite building finished products to the greatest extent, which reduces the workload of field operations and saves a lot of time. The building information model (BIM) technology assists in design and construction work to meet rapid construction requirements.

Endoscopic decompression of the optic canal for traumatic optic neuropathy.

Purpose: Traumatic optic neuropathy (TON) is a serious complication of head trauma with the incidence rate of 0.5%-5%. The aim of this study was to investigate the therapeutic efficacy of endoscopic decompression of the optic canal for optic nerve injuries.

[The expression of 5-HTR2B、E-cad、α-SMA in the pulmonary fibrosis in rats].

Objective: To observe the expression of 5-Hydroxytryptamine 2B receptor (5-HTR2B)、E-cadherin (E-cad)、alpha-smooth muscle actin(α-SMA) in the bleomycin -induced pulmonary fibrosis tissue of rats.

Methods: Forty-five healthy male SD rats were randomly di-vided into control group,bleomycin group and bleomycin+prednisone group(=15). Five rats in each group randomly sacrificed at the 7、the 14 and the 28 day after eastablishing models.

A Meta-Analysis and Indirect Comparison of Endothelin A Receptor Antagonist for Castration-Resistant Prostate Cancer.

Background: Endothelin A (ET-A) receptor antagonists including zibotentan and atrasentan, have been suggested as a treatment for castration-resistant prostate cancer (CRPC). Our aim was to conduct a meta-analysis and indirect comparison to assess the efficacy and safety of ET-A receptor antagonists for treatment of CRPC.

Methods: We systematically searched PubMed, EMBASE, the Cochrane Library, and Web of Science from inception to November 2014 to identify randomized controlled trials (RCTs) which assessed ET-A receptor antagonists for treatment of CRPC.

[Effects of snow pack removal on soil microbial biomass carbon and nitrogen and the number of soil culturable microorganisms during wintertime in alpine Abies faxoniana forest of western Sichuan, Southwest China].

To understand the effects of the lack of snow pack under global warming on the characteristics of soil microorganisms during wintertime, a snow-shading experiment was conducted in a primary fir (Abies faxoniana) forest after snow pack removal, with the soil microbial biomass carbon (MBC) and nitrogen (MBN) and soil culturable microorganisms (bacteria and fungi) at the stages of snow forming, snow covering, and snow melting investigated. Snow pack removal had significant effects on the soil MBC and MBN and the number of soil culturable bacteria and fungi, but the responses of the culturable microorganisms differed with the stages of snow-shading. Under the condition of snow pack removal, the MBC and MBN in soil organic layer decreased significantly at the early stages of snow forming and snow melting but increased significantly at snow covering stage and at the later stage of snow melting, and the number of culturable bacteria decreased significantly from the early stage of snow forming to the stage of snow covering while that of culturable fungi had a significant increase from the early stage of snow forming to the stage of snow melting.

[Zymohydrolysis with chondroitinase ABC and high performance liquid chromatography used for the determination of hyaluronic acid in shark fin].

A method for the determination of hyaluronic acid in shark fin by high performance liquid chromatography (HPLC) is described. At 37 degrees C, with 0.2 mol/L Tris-HCl buffer solution, hyaluronic acid was converted to the hyaluronic acid disaccharide by zymohydrolysis with chondroitinase ABC.
