The role of recombinant human brain natriuretic peptide on the cardiac output of patients with acute decompensated heart failure using Guyton venous return curve: A STROBE-compliant retrospective study.

rbBNP has positive cardiac effects in patients with acute decompensated heart failure, but its effects on the systemic venous circulation are not known.A single-center retrospective, self-controlled study was conducted on 14 patients undergone recombinant human brain natriuretic peptide (rhBNP) treatment between January 1, 2015 to December 31, 2018.The cardiac output (CO) significantly increased from 3.

Protects Against Renal Fibrosis by Regulating Intrarenal Fatty Acyl Metabolites.

Chronic renal failure (CRF) results in significant dyslipidemia and profound changes in lipid metabolism. (PPU) has been shown to prevent kidney injury and subsequent kidney fibrosis. Lipidomic analysis was performed to explore the intrarenal profile of lipid metabolites and further investigate the effect of PPU and its main bioactive component, ergone, on disorders of lipid metabolism in rats induced by adenine.

The Dysregulation of Eicosanoids and Bile Acids Correlates with Impaired Kidney Function and Renal Fibrosis in Chronic Renal Failure.

Chronic renal failure (CRF) is an irreversible deterioration of the renal functions that characterized by fluid electrolyte unbalance and metabolic-endocrine dysfunctions. Increasing evidence demonstrated that metabolic disturbances, especially dyslipidemia and profound changes in lipid and lipoprotein metabolism were involved in CRF. Identification of lipids associated with impaired kidney functions may play important roles in the understanding of biochemical mechanism and CRF treatment.

[Spatial and temporal evolution of habitat quality in Fujian Province, China based on the land use change from 1980 to 2018.].

Analyzing the characteristics of spatial-temporal evolution of habitat quality caused by land use change can provide a scientific basis for the coordinated development of regional ecological economy. With Fujian Province (the ecological civilization demonstration area of China) as an example,the InVEST model was used to evaluate the habitat quality based on the land use change data from 1980 to 2018. Further, the influencing factors were analyzed through Geodetector, and the spatial-temporal characteristics of habitat quality was analyzed by combining with the change of land use type.

Metabolomics in renal cell carcinoma: From biomarker identification to pathomechanism insights.

Renal cell carcinoma (RCC) is a frequently diagnosed cancer with high prevalence, which is inversely associated with survival benefit. Although myriad studies have shed light on disease causality, unfortunately, thus far, RCC diagnosis is faced with numerous obstacles partly due to the insufficient knowledge of effective biomarkers, hinting deeper mechanistic understanding are urgently needed. Metabolites are recognized as final proxies for gene-environment interactions and physiological homeostasis as they reflect dynamic processes that are ongoing or have been taken place, and metabolomics may therefore offer a far more productive and cost-effective route to disease discovery, particularly within the arena for new biomarker identification.

A novel PNPLA6 compound heterozygous mutation identified in a Chinese patient with Boucher‑Neuhäuser syndrome.

The combination of cerebellar degeneration, hypogonadotropic hypogonadism and chorioretinal dystrophy defines Boucher‑Neuhäuser syndrome (BNS), which has been associated with autosomal‑recessive mutations in the patatin‑like phospholipase domain containing 6 (PNPLA6) gene. However, no BNS cases have been reported in mainland China. In the present study, to the best of the authors' knowledge, the first patient with BNS was identified in China.

The imaging features of neurologic complications of left atrial myxomas.

Background: Neurologic complications may be the first symptoms of atrial myxomas. Understanding the imaging features of neurologic complications of atrial myxomas can be helpful for the prompt diagnosis.

Objective: To identify neuroimaging features for patients with neurologic complications attributed to atrial myxoma.

[FTIR microspectroscopic investigation of the age-related changes of subchondral bone of the knee in guinea pig].

Fourier transform infrared (FTIR) microspectroscopy was applied to in-situ analyse the chemical change of tibial articular subchondral bone of female Hartley guinea pigs with age increase. Three infrared absorption regions (a, b, c) of trabecular bone and central marrow region of the subchondral bone were measured for guinea pigs of different ages (1 months, 2 months and 3 months) using the infrared spectrum. Results show that (1) with months increasing, the total area of trabecular bone is increasing, meanwhile, the region a which is similar to normal trabecular bone spectra is decreasing, and region d waveform has the same trend as region a.

[Investigation of articular cartilage using FTIR microspectroscopy for guinea pig with spontaneous osteoarthritis].

In-situ analysis the chemical composition of tibial articular cartilage of female Hartley guinea pigs with Fourier transform infrared (FTIR) microspectroscopy was conducted. The infrared spectrum survey consists of three ages (1 months, 2 months and 3 months) and three cartilage layers (surface, middle and deep). The results demonstrated that with ages increasing, the peak positions of main absorbance bands in surface and middle shifted to a lower wavenumber, and in deep they shifted to a lower wavenumber first, then shifted to a higher wavenumber.

Genetic variation of new 21 autosomal short tandem repeat loci in a Chinese Salar ethnic group.

In the present study, we reported the allele frequencies for new 21 autosomal short tandem repeat (STR) loci, including D6S474, D12ATA63, D22S1045, D10S1248, D1S1677, D11S4463, D1S1627, D3S4529, D2S441, D6S1017, D4S2408, D19S433, D17S1301, D1GATA113, D18S853, D20S482, D14S1434, D9S1122, D2S1776, D10S1435 and D5S2500 loci. Forensic statistical parameters were estimated from a sample set of 120 unrelated healthy individuals from the Salar ethnic group in Xunhua Salar Autonomous County of Qinghai province, China. A total of 151 alleles were observed at 21 STR loci in the population, and their allele frequencies were in the range of 0.
