The liver is easily affected by a variety of factors to induce liver damage, which can cause disorders in the synthesis, detoxification, metabolism, and biotransformation functions of the liver in severe cases, and at present, there is still a lack of efficient clinical treatment methods for end - stage liver diseases such as liver failure and decompensated liver cirrhosis. Recent studies have confirmed the clinical efficacy of stem cells, and treatment methods based on stem cell - derived exosomes have become a research hotspot. This article introduces the advantages of treatment based on stem cell - derived exosomes, the re? search advances in related mechanisms, and the current status of preclinical research. Current research findings suggest that treatment based on stem cell - derived exosomes has a good application prospect in the treatment of liver diseases, but it is still needed to conduct in - depth preclinical and clinical studies.

Objective To investigate the risk factors for the 90-day prognosis of patients with decompensated liver cirrhosis and type I hepatorenal syndrome (HRS). Methods A retrospective analysis was performed for the clinical data of 299 patients with decompensated liver cirrhosis and type I HRS who were hospitalized in Beijing Ditan Hospital from October 2008 to October 2018, and according to the 90-day prognosis, they were divided into survival group with 135 patients and death group with 164 patients. The t-test was used for comparison of normally distributed continuous data between groups, and the Mann-Whitney U test was used for comparison of non-normally distributed continuous data between groups; the chi-square test was used for comparison of categorical data between groups. A multivariate binary logistic regression analysis was used to investigate the influencing factors for 90 day prognosis, and the receiver operating characteristic (ROC) curve was plotted for each factor. Results The univariate analysis showed that there were significant differences between the two groups in Model for End-Stage Liver Disease (MELD) score, Child - Turcotte - Pugh (CTP) score, hepatic encephalopathy, serum Na, (AST), total bilirubin (TBil), albumin (Alb), cholinesterase (CHE), white blood cell count (WBC), neutrophil (NE), neutrophil to-lymphocyte ratio (NLR), red blood cell count (RBC), red blood cell distribution width (RDW), platelet count (PLT), and international normalized ratio (INR) (P<0.05). The multivariate logistic regression analysis showed that Na (odds ratio [OR]=0.918, 95% confidence interval [CI]: 0.880-0.957, P<0.05), BUN (OR=1.077, 95% CI: 1. 0291. 127, P <0.05), RDW (OR=1.019, 95% CI: 1.005-1. 032, P<0.05), and INR (OR = 3.478, 95% CI: 2.096-5. 771, P<0.05) were independent influencing factors for poor 90-day prognosis in patients with decompensated liver cirrhosis and type I HRS. A predictive model, HRS-D, was established u sing the four factors above, and the ROC curves were plotted for each factor to calculate the area under the ROC curve (AUC), which showed that HRS -D had an AUC of 0.813 (95% CI: 0.762-0.864), with a sensitivity of 76. 50% and a specificity of 72. 50% at the diagnostic cut-off value of -1.264. There was a significant difference between HRS -D score and MELD score (Z=3.804, P<0.001), while there was no significant difference between HRS - D score and CTP score and between CTP score and MELD score (both P>0.05). Conclusion Na, BUN, RDW, and INR are independent influencing factors for poor 90-day prognosis in patients with decompensated liver cirrhosis and type I HRS, and the predictive model based on these indices can better predict the 90-day prognosis of HRS patients.

Vegetation cover and its pattern generally determine the hydrodynamics process and mechanisms in the runoff and sediment reduction. In this study, an indoor scouring experiment was carried out to investigate the variation characteristics of flow length index under different vegetation coverage and patterns. A relationship was established for the flow length index with the hydrodynamic parameters, yields of runoff and sediment in different vegetation patterns and coverage under different flow rates. Furthermore, the flow length index of the slope was proposed to serve as an indicator for measuring the effects of vegetation patterns on soil erosion. The results showed that: 1) The vegetation coverage significantly affected the hydrodynamic parameters. There were different trends of hydrodynamic parameters with the increase of vegetation coverage. The velocity and unit stream power presented a linear trend of increase relationship (P<0.01). There was an exponentially increasing trend in the roughness coefficient, resistance coefficient, and runoff shear stress. The increase of flow resistance and the decrease of kinetic energy can cause a gradual reduction in the amount of runoff yield and sediment production, where the greater the discharge was, the greater the reduction was. The vegetation reduced runoff yield and sediment production by changing the hydrodynamic parameters of water flow. 2) The flow length index, one of the important indexes of hydrological connectivity, was widely used in water and soil conservation. There were significant correlations between the flow length index and vegetation coverage, hydrodynamic parameters, as well as runoff and sediment production. Hydrodynamic parameters, runoff and sediment production varied with the flow length index. The velocity and unit stream power increased logarithmically, leading to the increase in the kinetic energy of slope flow. The roughness coefficient and the resistance coefficient presented a logarithmical decrease, indicating the decrease in the retardation capacity of the slope surface. But the runoff shear stress decreased exponentially, leading to the increase in the unit stream power of runoff. Obviously, the ability of slope block was declined, whereas, the erosion capacity of water flow was enhanced. This case finally led to the change of erosion status of the slope. There was also a logarithmic increase in the runoff and sediment yield of the slope. Thus, the flow length index with the aid of the flow path change can be used to indicate the hydrodynamic parameters of slope surface water flow and sediment yield in the change. Particularly the flow length index can be expected to serve as an indicator for the dynamic process of vegetation runoff and sediment reduction, and thereby predict the runoff and sediment yield on the slope. This finding can provide a scientific basis for the relationship between vegetation pattern and hydrological connectivity, and further establish vegetation patterns and evaluate vegetation impacts on erosion. The simulation experiments can contribute to the effective distribution and utilization of water resources for the regional ecological environment in modern agriculture. [ABSTRACT FROM AUTHOR]

To investigate the sustainability and ecological compensation standard for the runoff nutrient recycling system in rice-wheat rota⁃ tion systems, the environmental safety and sustainability of operations was analyzed based on emergy analysis and evidence of ecological compensation was proposed based on energy and material flow analysis over the entire life cycle of production practice; The payment stan⁃ dard based on the net emergy benefit difference was also calculated. Emergy analysis suggested that the environmental loading ratio was re⁃ duced by 39.62%, while the emergy sustainability index and environmental safety index were increased by 64.89% and 36.73% under the nutrient recycling system, respectively. Energy flow analysis showed that the biological auxiliary energy input was increased by 42.16%, while energy output through pollutants was reduced by 70.09%. Material flow analysis showed that the recycling system decreased nitrogen and phosphorus output to the surrounding water environment by 34.85% and 30.43%. Likewise, the net emergy benefit was lower by 2.15× 1016 Sej·hm-2·a-1 for the recycling system than for the conventional system. These results suggested that the recycling system improved envi⁃ ronmental safety but reduced economic profit, which thus required ecological compensation for its ecosystemic services, and the payment standard was estimated to be 4 153.78 yuan·hm-2·a-1.

[Objectives]In order to reconcile the debate about the effects of straw incorporation,this study aims to investigate the effects of straw incorporation on crop yields in the rice-wheat rotation systems,and provide theoretical support for the extension of straw return method. [Methods]We utilized rice-wheat rotation system in the Yangtze River basin as our model system,collected the data from 122 trials in 27 publications and conducted Meta-analysis to investigate the response of crop yield to straw incorporation,as well as the potential factors which might affect the response pattern,including straw return amount,N type as basal fertilizer,N,P,K fertilizer amount,soil type,tillage and cultivation methods and climate,etc. [Results]Both the yield of wheat and rice was positively increased by straw return. But rice yield showed a bigger magnitude than wheat yield. Multiple factors affected the yield of rice and wheat to straw incorporation. Wheat yield was not affected by different rice straw amounts,but rice yield significantly increased when the wheat straw amount was more than 3 750 kg·hm-2. In the lower Yangtze River basin,rice straw incorporation significantly reduced wheat yield,while it increased at the median and upper Yangtze River basin agricultural regions. Urea as basal N fertilizer will increase but compound fertilizer as basal N fertilizer did not affect the response of wheat yield to rice straw return. Under rice straw incorporation,wheat yield was significantly reduced when N fertilizer amount was greater than 200 kg·hm-2;however,it significantly increased when N amount was less than or equal to 200 kg·hm-2. The optimum P amount was 40-60 kg·hm-2,under which conditions,straw incorporation significantly increased both rice and wheat yields. The K fertilizer amount did not affect the effects of straw return on both crop yields. Wheat straw return significantly reduced rice yield in the fluvo-aquic soils. The soil organic matter (SOM)content of 20-30 g·kg-1 will promote the positive effects of straw return on both crop yields. However,when the SOM content was high,i.e.,greater than 30 g·kg-1,rice straw return reduced wheat yield. Other soil attributes,including total nitrogen,available phosphorus,available potassium and pH,did not affect the straw return effects. Rotary tillage reduced wheat yield under rice straw incorporated;however,other tillage methods positively affected the straw return effects on both crop yields. Compared with seedling broadcasting and direct-seeding,manually transplanting significantly increased the positive response of rice yield to wheat straw return. In summary,rice yield was significantly increased by wheat straw return,while wheat yield was not affected by rice straw incorporation. [Conclusions]The response of rice and wheat yield to straw return is a complicated process,which is determined by straw return amount,climate,tillage and cultivation method,fertilization regime and soil attributes.

This study aims to integrate the ‘Crab-Grass-Snail' system and the ‘Cultivating-Purifying' system into a more comprehensive recycling ecosystem, and theoretically investigate the engineering practice to meet the III type surface water standard. Through constructing a system dynamic model, this study simulated the optimal area ratio between crab cultivation pond and purification pond, as well as testing the effects of feed substitution ratio, water quality regulation technology and purifying efficiency on TN and TP concentration. The simulation results showed that the optimal area ratio for cultivation pond and purification pond was 20.5 to meet the III type surface water standard. It was reduced by 3.1%, 6.3% and 10.0% for TN concentration and by 4.2%, 8.3% and 8.3% for TP concentration in the cultivation pond with a substitution of commercial feeds for 5%, 10%and 15%, respectively. TN concentration was decreased by 4.5%, 10.1%and 14.6%in the purification pond with a substitution of commercial feeds for 5%, 10%and 15%, respectively. Water quality regulation technology did not affect TN and TP concentration in the cultivation and purification ponds. Compared with one time’s harvest for water hyacinth, it was reduced 10.0% and 10.0% for TN concentration and 11.1% and 11.1% for TP concentration in the cultivation pond by harvest two times and three times, respectively. TN concentration was decreased by 16.1%and 17.2%in the purification pond. In summary, N and P input from commercial feeds were an important cause for the over-range of N and P concentration in the residue water. TN and TP concentration will decrease with increasing substitution rate for commercial feeds in the cultivation and purification ponds. It needs only to harvest two times for water hyacinth when the purifying water will meet the III type surface water standard. These results will provide theoretical evidence for engineering design and the mating management practice for the crab ecological cultivation. [ABSTRACT FROM AUTHOR]

Salinomycin, extensively used as an antibiotic in animal husbandry for a long time, has recently been found to possess strong anti-cancer and anti-cancer stem cell efficacy, as well as activities to overcome multi-drug resistance of tumor based on studies in vivo and in vitro in case reports in pilot clinical trials. Therefore, salinomycin promised to be a novel anti-cancer agent. However, the unfavorable property of poor aqueous solubility and the adverse effects of salinomycin were greatly hinder its clinical use. In order to improve its therapeutic index and alleviate its toxicity, studies on nanotechnology-based delivery systems of salinomycin had been widely conducted. In this article, the latest development and application of salinomycin nanoformulations were reviewed. [ABSTRACT FROM AUTHOR]
