Objective: To investigate the relationship between the expression of serum long non-coding RNA taurine up-regulated gene 1 (LncRNA TUG1) and microRNA-29a-3p (miR-29a-3p) and the degree of lesion, lung function and phosphatidylinositol 3 kinase (PI3K)/protein kinase B (Akt)/rapamycin target protein (mTOR) signaling pathway in patients with idiopathic pulmonary fibrosis (IPF). Methods: 52 IPF patients (study group) admitted to our hospital from January 2021 to December 2023 were selected, and 50 healthy volunteers (control group) who underwent physical examination in our hospital during the same period were selected. The levels of serum LncRNA TUG1, miR-29a-3p, lung function parameters [total lung capacity (TLC), forced expiratory volume in the first second as a percentage of predicted value (FEV1%pred), forced vital capacity (FVC), carbon monoxide diffusion capacity as a percentage of predicted value (DLCO%pred)], high-resolution computed tomography (HRCT) score and PI3K, Akt and mTOR mRNA expression were com- pared in two groups. The correlation was analyzed by Pearson method. Results: The expression levels of serum LncRNA TUG1, PI3K, Akt and mTOR mRNA in study group were higher than those in control group, and the expression level of miR-29a-3p was lower than that in control group (P<0.05). TLC, FEV,%pred, FVC and DLCO%pred in study group were lower than those in control group, and HRCT score was higher than that in control group (P<0.05). The expression of serum LncRNA TUGI was positively correlated with HRCT score, PI3K, Akt and mTOR mRNA expression, and negatively correlated with TLC, FEV1%pred, FVC and DLCO%pred (P<0. 05). And miR-29a-3p was negatively correlated with HRCT score, PI3K, Akt and mTOR mRNA expression, and positively correlated with TLC, FEV,%pred, FVC and DLCO%pred (P<0.05). Conclusion: Serum LncRNA TUGI is highly expressed, and miR-29a-3p is lowly expressed in IPF patients, the two are closely related to the degree of lung tissue lesions, the degree of lung function damage and the abnormal activation of PI3K/Akt/mTOR signaling pathway in IPF patients [ABSTRACT FROM AUTHOR]

目前,众多寄生性杜鹃里,大杜鹃(Cuculus canorus)的宿主种类最多,白鹡鸰(Motacilla alba)作为其中的宿主之一,尚未发现其寄生巢、卵的相关数据。2019—2021年,通过在贵州六枝地区搜索并记录白鹡鸰巢的方法,收集白鹡鸰相关数据,以了解白鹡鸰巢址情况及基础繁殖参数,并于2020年6月16日在白鹡鸰巢中首次发现大杜鹃的寄生卵。通过模型卵识别实验,检测白鹡鸰卵识别能力,拒绝率较高,表明白鹡鸰可能已具备识别并拒绝外来卵的能力。对大杜鹃寄生巢及卵的记录,补充了大杜鹃—白鹡鸰寄生系统中寄生卵相关数据的空缺,初步了解该寄生系统中大杜鹃卵的模拟程度。

In order to optimize the parameters of pump-stopping water hammer protection equipments for high-lift and multi-fluctuation water pipelines with considering reliability and economy, BP neural network was built to simulate the hydraulic transition process. The parameters of air valve and one-way surge tank were taken as decision variables, and the Pareto optimal solution set was obtained by cooperating with multi-objective genetic algorithm (NSGA-II). Entropy weight-TOPSIS method was used to determine the best decision. The method was applied to an engineering example. The results show that compared with the initial scheme, the optimized scheme provides similar positive pressure protection effect with the volume of the one-way surge tank less than 92.06%, and the minimum negative pressure along the pipeline is increased by 49.28%. Compared with no protective measures, while meeting the pressure resistance capacity of the pipeline, the maximum difference between the maximum and minimum pressure and yield capacity along the pipeline is decreased by 84.03% and 65% respectively. The method can realize the effective connection between the water hammer protection calculation and the intelligent optimization algorithm when the pump is stopped, and determine the reliable and economical parameters of the water hammer protection equipment when the pump is stopped [ABSTRACT FROM AUTHOR]

Nonalcoholic fatty liver disease （NAFLD） is currently the main cause of chronic liver disease worldwide, and it can progress to hepatitis, liver fibrosis, liver cirrhosis, and even hepatocellular carcinoma. Although obesity plays a key role in the development of NAFLD, more and more studies have confirmed that NAFLD still exists in lean individuals, and lean NAFLD is associated with an increased risk of death and accelerated disease progression. Therefore, lean NAFLD also deserves careful evaluation and follow-up; however, we still know little about the pathophysiological mechanism of lean NAFLD. This article reviews the etiology, diagnosis, treatment, and prognosis of lean NAFLD. [ABSTRACT FROM AUTHOR]

Catalytic oxidation has been widely used in CO elimination. A single-dispersed porous microsphere catalyst CuMn2O4 and its graphene composite material CuMn2O4@GA are synthesized. The material structure is characterized by scanning electron microscopy(SEM), X-ray diffraction (XRD) and other methods. The results show that the hydrothermal method is an ideal method for the synthesis of graphene composite. The structure of CuMn2O4@GA is stable and uniform, and the catalyst particles are fully dispersed in the aerogel. Catalytic performance test shows that the adsorption and the conversion behavior of CO on the surface of CuMn2O4 is closely related to its morphology. Benefiting from the low-density network structure of CuMn2O4@GA, complete conversion of CO is achieved at a high gas flow of 60000 mL/（g（cat)·h) and 128 ℃. The water of the inlet gas has no significant effect on the catalytic activity of CuMn2O4@GA. Multiple repeated activation and use test show that CuMn2O4@GA has good structural integrity and excellent economy. [ABSTRACT FROM AUTHOR]

The experiment was to investigate the effect of different mixing ratio on the quality of mixed silage of Indigofera amblyantha Craib and Paspalum wettsteinii Hack. Two separate silages of Indigofera amblyantha Craib (CK1) and Paspalum wettsteinii Hack (CK2) were used as control, and the fresh mass ratios of Indigofera amblyantha Craib to Paspalum wettsteinii Hack were set at 1∶1 (I1P1), 1∶2 (I1P2), 1∶3 (I1P3) and 1∶5 (I1P5), respectively, for mixed silage with three replicates in each treatment. Silage was fermented for 70 d, and the nutrient composition and fermentation quality were determined. The results showed that all the mixed silages in different mixing ratio showed great silage quality scores in the sensory evaluation. Following the decrease of the ratio of Indigofera amblyantha Craib in mixed silage, the content of dry matter, crude protein, water soluble carbohydrates, lactic acid and pH decreased, while the content of acetic acid increased. But there was no significant difference in the content of neutral detergent fiber (P>0.05). Grey correlation analysis demonstrated that the best mixed silage quality was occurred in CK1 group, and the I1P2 group was the second. The study indicates that from the perspective of forage processing and utilization of artificial mixed seeding grassland, it is suitable to make silage with Indigofera amblyantha Craib and Paspalum wettsteinii Hack in 1∶2 mixing ratio.

The polypeptides from fruiting bodies of Volvariella volvacea were extracted by alkaline protease enzymatic hydrolysis, and purified by dialysis method to yield three different components (3 to 10, 1 to 3, and less than 1 kDa). The antioxidant activities in vitro of the three components were compared. The structure of purified polypeptide was characterized by LC-MS/MS, ultraviolet absorption spectroscopy, Fourier transform infrared spectroscopy, and amino acid determination methods. The result showed that the antioxidant activity of 1 to 3 kDa was strongest. The 1,1-diphenyl-2-picrylhydrazyl (DPPH) free radical clearance rate was 99.81%, the ferric ion reducing ability was 1.47, and the clearance rates of 2,2′-azino-bis (3-ethylbenzothiazoline-6-sulfonic acid) (ABTS+ ) radical and hydroxyl radical were 99.15% and 99.34%, respectively. The total protein content of the antioxidant peptide of V. volvacea at this molecular weight was 71.12%, ash content was 12.75%, moisture content was 8.44% and the others were 7.69%. The results of structural identification showed that the polypeptides from fruiting bodies of V. volvacea were high quality protein materials. [ABSTRACT FROM AUTHOR]
