To investigate the relationship between intraspecific variation in plant functional traits and neighborhood competition and soil, young trees of 12 subtropical tree species were selected as research objects to analyze the differences in six common traits (specific leaf area, leaf area, leaf dry matter content, leaf nitrogen content, leaf phosphorus content, and leaf thickness) related to the acquisition and utilization of plant resources, to explore the degree of intraspecific variation in different plant functional traits, and the influence of neighborhood competitional and soil factors on the variation of these traits. The aim was to explore the degree of intraspecific variation in different plant functional traits and influence of neighborhood competitional and soil factors on these variations. The results showed that the six leaf traits exhibited different degrees of variability. Specific leaf area had the highest coefficient of variation, ranging from 16. 71% to 55. 31%, whereas leaf dry matter content had the lowest variability within the study species. Both neighborhood competition and soil factors influenced changes in leaf traits, with neighborhood competition playing a more significant role. Neighborhood competition index and neighborhood height index had significant positive effects on comparative leaf area and leaf phosphorus content (P＜0. 05). In contrast, leaf area and dry matter content significantly decreased with increasing neighborhood height index (P＜0. 05). Leaf nitrogen content was affected only by soil pH value. In addition, soil water content, soil carbon content, and soil bulk density contributed to variations in leaf traits. Therefore, when creating plantation forests, the relationship between plant functional traits and environmental adaptation should be considered. [ABSTRACT FROM AUTHOR]

Objective To establish a mouse model of human Escherichia coli (E. coli) colonization in early mammalian intestines，and to explore the trend and influencing factors of E. coli colonization in mouse intestines. Methods A wild-type E. coli strain LFYP5, derived from an infant, was inoculated into the SPF mice via gavage. The abundance change curves of E. coli were plotted by collecting intestinal contents or fecal samples from the mice and utilizing plate counting colony forming unit (CFU) methods. This study investigated the effects of different intestinal locations, inoculation ages, weaning time, and cage-changing time on the colonization abundance of E. coli. Additionally，16S rRNA sequencing was used to explore the changes in the microbial composition of the mouse gut after inoculation with E. coli. Results E. coli LFYP5 was able to colonize the intestinal tract of mice before the weaning age. Its abundance decreased rapidly at the weaning stage, independent of the inoculation age, and whether to change the cages. When weaning occurred too early, the abundance of E. coli declined correspondingly earlier. Mice inoculated with E. coli LFYP5 had a lower alpha diversity of the gut microbiota composition and higher relative abundance of the lactobacillus genus compared to mice without E. coli LFYP5 inoculation. Conclusion A mouse model of human E. coli colonization in the early mammalian gut has been successfully established. This model may be used to study the colonization mechanisms of human E. coli in the mammalian gut in the future. [ABSTRACT FROM AUTHOR]

Malignant tumors pose a serious threat to human health and are one of the main causes of human death worldwide. In order to further improve the therapeutic outcomes of malignant tumors and prolong patients' survival time, clarifying the pathogenesis of malignant tumors and searching for new diagnostic and therapeutic targets become particularly important. It has been found that the occurrence and development of malignant tumors are the results of the interaction between tumor cells and the tumor microenvironment (TME). Versican, encoded by the VCAN gene, is a type of chondroitin sulfate proteoglycan belonging to the exogenous lectin proteoglycan family. It is a major component of the extracellular matrix and plays an important role in embryonic development and inflammatory responses. As an important component of TME, versican is abnormally expressed in various tumor tissues such as renal cell carcinoma, hepatocellular carcinoma, and gastric cancer, and is closely related to the clinical pathological characteristics and prognosis of the patients. It is a potential biomarker for early diagnosis and prognostic evaluation of tumors. Further researches have shown that versican can promote tumor development in a number of ways, such as promoting tumor cell proliferation, invasion and metastasis, inhibiting tumor cell apoptosis, promoting tumor angiogenesis, and inhibiting anti-tumor immune responses. This article reviews the current research status of the expression and biological effects of versican in malignant tumors, aiming to provide reference for subsequent research, clinical diagnosis and treatment of tumors.

Objective To explore the application value and operation skills of ultrasound-guided percutaneous thermal ablation assisted by artificial ascites or/and soft tissue edema in the treatment of special hepatic tumors located nearby the diaphragm, heart, stomach, gastrointestinal tract, gall bladder, kidney, and other organs. Methods The clinical data of 132 patients with special-region hepatic tumors treated with ultrasound-guided percutaneous thermal ablation aided by artificial ascites and/or artificial soft tissue edema were retrospectively analyzed. Intraoperative contrast-enhanced ultrasound was used to guide ablation when necessary. During the operation, the ablation needle was lifted or pressed down, or the direction of the needle handle was changed to protect vital organs. The technical success rate of artificial ascites and/or soft tissue edema formation, the complete in activation rate of the tumor, and the complications were observed. Results There were 74 patients (108 lesions) treated with radiofrequency ablation and 58 patients (82 lesions) treated with microwave ablation. Among them, 81 cases was successfully injected artificial abdominal ascites, with a water volume of (1 301±685) ml; artificial soft tissue edema was successfully formed for 19 patients, with a water volume of (534±258) ml. Both artificial ascites and artificial soft tissue edema were built for 30 patients. The success rate of this hydro-isolation technique was 98.5% (130/132). 129 patients successfully completed the treatment, and the complete inactivation rate of the tumor was 92.5% (172/186). The average postoperative hospital stay was three days. No patient had serious complications, such as surface tumor rupture, gastrointestinal injury, or diaphragm perforation. Conclusions For hepatic tumors located adjacent to other organs such as the diaphragm, heart, gastrointestinal tract, gallbladder, and kidney, the application of artificial ascites and/or artificial soft tissue edema can reduce the damage to these organs, as well as reduce the possibility of tumor rupture and diaphragm perforation. These methods are safe and effective in ultrasound-guided percutaneous thermal ablation. [ABSTRACT FROM AUTHOR]

In order to investigate the effect of extraction methods, including cold pressing method, soxhlet method and aqueous enzymatic method, on the quality of walnut oil, and explore the key chemical components affecting the antioxidant activity of walnut oil. The physicochemical properties, chemical compositions and antioxidant activities of the walnut oils extracted by the extraction methods mentioned above were determined. In addition, the antioxidant evaluation model of walnut oil was established through multiple linear regression analysis to analyze the key chemical components, affecting the antioxidant activity of walnut oil. The results showed that the three extraction methods had little effect on the content and compositions of fatty acids and glycerides in walnut oil, but had great influences on the contents of total phenols and flavonoids, physicochemical properties and antioxidant activities of the oils. According to the antioxidant evaluation model of walnut oil, linoleic acid and total phenols were the key chemical components affecting the antioxidant activity of walnut oil. In conclusion, among the three extraction methods, the quality of walnut oil extracted by cold pressing method is the best, followed by that obtained by aqueous enzyme method. However, the yield of walnut oil extracted by aqueous enzyme method was higher than that by cold pressing method. More importantly, aqueous enzyme method can simultaneously produce bioactive peptides during the process of oil extraction, so it is a extraction method with great potential for application.

Bloomfield has repeatedly stressed the important influence of behaviorism on linguistics, but there is still much controversy about the relationship between the them. Based on Bloomfield’s Language, the authors introduce the historical sources of description methods by means of literature reduction and comparison, and discuss the language description methods from the perspective of comparative philosophy of science and history of linguistics. It is believed that the important feature of the description method is that it emphasizes the scientific nature of the description process, which is an important method of language research. This method is deeply influenced by the scientific philosophy of behaviorism. [ABSTRACT FROM AUTHOR]

Objective: To investigate the levels of serum microRNA (miR)-210, β2 microglobulin (β2-MG) and transforming growth factor-β1 (TGF-β1) in dilated cardiomyopathy (DCM), and to analyze its value in diagnosing DCM and predicting the prognosis of DCM. Methods: From August 2016 to August 2018, 105 cases of DCM patients (DCM group) who were treated in our hospital and 63 physical examination volunteers (control group) were selected. DCM patients were divided into survival group (76 cases) and death group (29 cases) according to whether cardiogenic death occurred during follow-up. Serum miR-210, β2-MG and TGF-β1 expression levels, echocardiographic indexes and other laboratory indexes were detected. Pearson analyzed the correlation between miR-210, β2-MG and TGF-β1 and echocardiography and other laboratory indexes. Receiver operating characteristic (ROC) curve analysis miR-210, β2-MG and TGF-β1 the value of diagnosing DCM and predicting the prognosis of DCM. Results: The miR-210, β2-MG, TGF-β1, high sensitivity C-reactive protein (hs-CRP), creatine kinase isoenzyme (CK-MB), troponin I (cTnI), B-type brain natriuretic peptide (BNP) levels, left ventricular end diastolic diameter (LVEDD), left ventricular end diastolic volume (LVEDV), E peak to ventricular septal distance (EPSS) and left ventricular end systolic volume (LVESV) in DCM group were higher than those in control group (P<0.05), and left ventricular ejection fraction (LVEF) was lower than that in control group (P<0.05). The serum miR-210 and β2-MG and TGF-β1 levels in the death group were higher than those in the survival group (P<0.05). The serum miR-210, β2-MG and TGF-β1 levels of DCM patients were positively correlated with CK-MB, cTnI, BNP, LVEDD, LVEDV, EPSS and LVESV (P<0.05), and negatively correlated with LVEF (P<0.05). TGF-β1 was positively correlated with hs-CRP(P<0.05). The areas under the curve (AUC) of miR-210, β2-MG and TGF-β1 for diagnosing DCM and predicting prognosis of DCM were 0.600, 0.639, 0.615 and 0.628, 0.632, 0.634, the AUC of DCM diagnosis and prognosis prediction combined with the three indexes were 0.885 and 0.863 (P<0.05). Conclusion: The serum miR-210, β2-MG and TGF-β1 levels of DCM patients are increased, which is associated with left heart remodeled, myocardial injury and poor prognosis, and can be used as auxiliary indexes of DCM diagnosis and prognosis prediction.

Objective　To further explore the regulatory mechanism of miR-145 in Endometriosis （EMs） through cell experiments. Methods　miR-145 or octamer-binding transcription factor 4 （OCT4）gene and protein expression levels in cells were examined using reverse transcription-quantitative PCR and western blotting， respectively. Correlation analyses and dualluciferase reporter assays were performed to assess the association between miR-145 and OCT4. A Cell Counting Kit-8 assay was performed to test cell viability，while cell apoptosis was measured using flow cytometry. Moreover，the migration of hESCs was measured via Transwell assays. Results　In cell assays，overexpression of miR-145 signifcantly promoted proliferation and migration （ P < 0.01），but inhibited the apoptosis of hESCs （ P < 0.05）. Furthermore，the transfection of hESCs with miR-145 mimics decreased the protein expression levels of OCT4，Bax and MMP1 （ P < 0.01），as well as increased the protein expression of Bcl2. However，knockdown of miR-145 reversed these results and significantly inhibited the proliferation of hESCs by targeting OCT4 （ P < 0.05）. Conclusion　The present results suggested that knockdown of miR-145 signifcantly suppressed the development of EMs by targeting OCT4，which may serve as a potential target for the treatment of EMs. [ABSTRACT FROM AUTHOR]
