Diagnosis and treatment of an elderly patient with 2019-nCoV pneumonia and acute exacerbation of chronic obstructive pulmonary disease in Gansu Province: A case report.

Background: In December 2019, the first patient with 2019-novel coronavirus (2019-nCoV) was reported in Wuhan, China, and the disease spread rapidly across the country and surrounding countries within 2 mo. As of February 29, 2020, a total of 91 confirmed cases had been reported in Gansu Province. This case report of the diagnosis and treatment of an elderly patient with 2019-nCoV pneumonia complicated by acute exacerbation of chronic obstructive pulmonary disease in Gansu Province aims to provide a better reference for the treatment of patients in the future.

[Retracted] Effects of the eukaryotic initiation factor 6 gene on expression levels of inflammatory mediators in M2 macrophages during scar repair.

Following the publication of this article, we regret to report that we have been unable to reproduce the results presented in the paper in our subsequent studies. At the present time, we have not been able to ascertain the reason behind this. Therefore, we would like to retract this article from publication.

Effects of the eukaryotic initiation factor 6 gene on expression levels of inflammatory mediators in M2 macrophages during scar repair.

The aim of the present study was to evaluate the effects of the eukaryotic initiation factor 6 (eIF6) gene on the secretion of M2 macrophage fibrosis‑associated factors and the expression levels of key proteases during scar repair. Male eIF6 wild‑type (eIF6+/+) and knockout (eIF6+/‑) C57BL/6 mice were intraperitoneally lavaged to obtain macrophages, which were induced to the M2 type using interleukin‑4. Differences between the gene expression profiles of these macrophages were compared with gene microarrays, and the results were validated using reverse transcription-quantitative polymerase chain reaction analysis and ELISA.

[Influence of high-voltage electrical burn on the rheological property of platelet and leukocyte in rats and the interventional effect of pentoxifylline].

Objective: To investigate the influence of high-voltage electrical burn (HEB) on the aggregation and adhesion of platelet and leukocyte in rats and the interventional effect of pentoxifylline (PTX).

Methods: One hundred and eighty SD rats were divided into control, electrical burn (EB), and pentoxifylline treatment (PT) groups according to the random number table, with 60 rats in each group. (1) Ten rats were taken from each group at 15 minutes before injury for the observation of the microcirculatory perfusion of chest skin with Laser Doppler Perfusion Imager (LDPI), and the number of leukocyte adherent to mesenteric venule with Bradford Variable Projection Microscope (BVPM).

[Clinical effect of the concentrated suture fixation method on skin transplantation in the jaw and neck region].

Objective: To observe the clinical effect of the concentrated suture fixation method on skin transplantation on deep burn wound or wound of cicatricial deformity after burn in the jaw and neck region.

Methods: One hundred and fourteen patients, hospitalized from April 2002 to December 2011, with deep burn or cicatricial deformity after burn in the jaw and neck region, were divided into packaging group and concentrated suture group according to the random number table. Each group had 57 patients including 48 cases with deep burn and 9 cases with cicatricial deformity.
