The complete mitochondrial DNA sequence of Yimeng black goat () and its potential application in mutton discrimination.

Yimeng black goat is one of the national breeds of geographical indication in China and is one of the key protected local livestock and poultry breeds of Shandong province. The complete mitochondrial genome sequence of Yimeng black goat was investigated in this study (GenBank accession no. MT134111).

[Clinical Utility of Revised Cardiac Risk Index to Predict Perioperative Cardiac Events in Elderly Patients with Coronary Heart Disease Undergoing Non-cardiac Surgery].

Objective To explore the predictive ability of the revised cardiac risk index(RCRI)in elderly patients with coronary heart disease(CHD)undergoing non-cardiac surgery. Methods We performed a retrospective study including a total of 2100 patients,aged≥65 with a history of CHD who underwent non-cardiac surgery form January 2013 to September 2019.The preoperative,intraoperative and postoperative clinical data were extracted from an electronic database.

CT imaging of the COVID-19.

COVID-19 pneumonia presented with certain characteristic chest CT imaging features, which are helpful to the radiologist in the early detection and diagnosis of this emerging global health emergency. In this report, we present chest CT findings from five patients with COVID-19. Except for one case with normal lung appearance, all the other four cases had certain characteristics, including ground-glass opacity (GGO), consolidation and atoll sign.

inhibition of proliferation, migration and epithelial-mesenchymal transition of human lens epithelial cells by fasudil.

Aim: To study the potential role of fasudil as a treatment for posterior capsular opacification (PCO) of the human crystalline lens.

Methods: Human lens epithelial cells (HLECs; line SRA01/04) was exposed to transforming growth factor-β2 (TGF-β2) to induce the process of epithelial-mesenchymal transition (EMT). Fasudil was applied to the cell samples.

[Nitrogen Removal Effect and Conversion Characteristics of Nitrous Oxide in Single-stage and Multi-stage A/O Processes].

The single-stage A/O and multi-stage A/O processes were simulated by sequencing batch reactors (SBRs) with alternate stirring and aeration. The removal efficiency of nitrogen and the release mechanism of NO were studied under the identical conditions of influent quality, hydraulic retention time (HRT), sludge retention time(SRT), temperature and anoxic/oxic (A/O) retention time ratio. Experimental results showed that COD or ammonia-nitrogen removal had no significant difference between the single-stage and the multi-stage A/O processes for the influent quality equivalent to municipal wastewater.

Characteristics and visual outcomes of patients hospitalized for ocular trauma in central China: 2006-2011.

Aim: To complete the data of ocular trauma in central China, as a well-known tertiary referral center for ocular trauma, we documented the epidemiological characteristics and visual outcomes of patients hospitalized for ocular trauma in this region.

Methods: A retrospective study of patients hospitalized for ocular trauma in central China from 2006 to 2011 was performed.

Results: This study included 5964 eyes of 5799 patients.

[Effect of cytokine and sandostatin on collagen synthesis and expression of procollagen mRNA by lens epithelial cells].

Objective: To study the effects of epidermal growth factor (EGF), interleukin-1 (IL-1), interferon-gamma (IFN-gamma) and sandostatin on collagen synthesis and expression of types I and III procollagen mRNA by bovine lens epithelial cells in vitro.

Methods: Cells were plated in 96-well tissue culture plates. After attached, serum-free medium containing EGF 10(-2) - 10(2) ng/ml, IL-1 10 - 10(5) ng/ml, sandostatin 10(-11) - 10(-7) mol/L and IFN-gamma 10 - 10(5) U/ml were added into the plates.
