Abstract： Consumer guilt refers to negative feelings caused by consumer’s behavior that violates social norms or individual values. Consumer guilt exists universally in college students who are not economically independent yet but have a strong willingness to consume. However, few studies have systematically examined what caused consumer guilt in college students. Related research showed that people with different socioeconomic status (SES) had different psychological experience during consuming. Therefore, the level of consumer guilt may vary in college students with different SES. College students’ parents bring them up and also provide them financial support. As main factors of parent-child relationship, Parenting styles and parent-child communication probably moderate the relationship between SES and consumer guilt. Materialism is a value emphasizing the importance of material wealth in individual life. Individuals with high materialism are more likely to engage in irrational consumption, which leads to consumer guilt. That means different level of materialism probably influences the relationship between SES and consumer guilt. Therefore, the current study aims to explore the relationship between SES and consumer guilt. Furthermore, the current study also explores the moderating effects of parenting styles, parent-child communication, and materialism on the relationship between SES and consumer guilt. The current study recruited 560 college students online, who were from different Chinese universities(Mage = 20.94±1.99 years, 266 females). 560 participants completed questionnaires on anticipated and reactive consumer guilt, objective and subjective socioeconomic status, parenting styles, parent-child communication, and materialism. SPSS 26.0 and PROCESS 4.1 were used to analyze data. The results showed that:(1) Objective SES significantly negatively predicted both anticipated consumer guilt and reactive consumer guilt, but subjective SES had no significant effect on anticipated and reactive consumer guilt. (2) Parenting styles and parent-child communication moderated the relationship between objective SES and consumer guilt. When parenting styles(high parents’ emotional warmth、low parents’ rejection and low father’s over protection) and parent-child communication (high conversation、low conformity) were positive, objective SES could significantly negatively predict consumer guilt; when parenting styles and parent-child communication were negative, objective SES had no significant effect on consumer guilt. (3) Materialism had no significant moderating effect on the relationship between objective SES and consumer guilt. The results indicate that objective SES may influence college students’ consumer guilt, and the protective role of family factors on the influence is more reflected in high objective SES college students.

Abstract： The decline in seedling growth of Malania oleifera as the age increases is often observed in the absence of host plants. A better knowledge of nutrient dynamics in terms of concentration and distribution patterns in different parts of the declining seedlings can provide valuable information for evaluating seedling growth vigor and offer scientific guidance for rational fertilization in M. oleifera nurseries. In this study, the concentrations of N, P, and K were comparatively analyzed in various organs of unattached M. oleifera seedlings grown for half a year, two years, and three years. Additionally, the starch content and distribution patterns in the roots and stems of seedlings with different vigor levels were qualitatively assessed by staining cross-sections. The results were as follows: (1) As the growth vigor of M. oleifera seedlings declined, the concentrations of N, P, and K in most organs decreased, except for a significant increase in K concentration in lateral roots. The leaf N/P ratios of the declining seedlings became increasingly imbalanced, indicating different nutrient deficiency types among the seedlings with varying decline degrees. Unattached M. oleifera seedlings grown for half a year were primarily limited by insufficient N supply (with an average N/P ratio of 11.33) and subsequently by P limitation after two years (average N/P ratio 17.81). The leaf N/P ratio of unattached M. oleifera seedlings grown for three years was remarkably imbalanced (with an average value of 52.46). As the growth vigor of unattached three-year seedlings is considerably low, they are deemed unsuitable for afforestation. (2) A decrease in starch content was observed in declining seedlings, as evidenced by the reduced staining intensity of cross-sections. After three years, the starch content of unattached M. oleifera seedlings was found to have decreased to an extremely low level. Significant differences in starch content were observed at various locations, including the connecting point of the stems and roots, the basal swelling top of the root, the main root, and lateral roots, among seedlings with different degrees of decline. These findings suggest that starch content levels can serve as crucial criteria for evaluating the growth vigor of seedlings. Specifically, lateral roots were identified as optimal sampling materials for assessing seedling growth vigor through a minimally invasive method.

Abstract：
Objective To evaluate the methodological quality and reporting quality of guidance documents for non-alcoholic fatty liver disease using the AGREE II and RIGHT tools, summarize and compare the recommendations,and provide a reference for the development and reporting of future guidelines for non-alcoholic fatty liver disease.Methods PubMed, CNKI and other Chinese and English databases were searched by computer,with a search time frame of 1 September 2012 - 1 September 2022.Two trained evaluators independently evaluated the methodological and reporting quality of the included guidance documents using AGREE II and RIGHT respectively, and collated and compared the recommendations of the higher quality guidance documents.Results A total of 19 publications were included, including 12 guidelines and 7 consensus; 6 in Chinese and 13 in English; and 10 are developed using an evidence-based approach. The mean scores for each domain of AGREE II are 42.84% for scope and purpose, 31.43% for participants, 31.25% for rigour, 60.67% for clarity, 32.68% for application and 37.5% for independence. The average scores of RIGHT in each area are: basic information (59.65%), background (66.12%), evidence (42.11%), recommendations (39.85), review and quality assurance (17.11%), funding and conflict of interest statement and management (18.42%), and other aspects (47.37%).Evidence-based guidance documents has higher mean scores in AGREE II and higher quality of reporting in RIGHT than non-evidence-based guidance documents.Foreign guidance documents has higher mean scores in AGREE II and higher quality of reporting in RIGHT than domestic guidance documents.The main recommendations relate to screening and diagnosis, assessment, management (non-pharmacological and pharmacological treatment) and surgical treatment. Conclusion The methodological quality and reporting quality of the published guidance documents for NAFLD still need to be improved, and there are still gaps between domestic guidance documents and international guidance documents.The development of TCM guidance documents should follow an evidence-based approach.Further reference should be made to international standards such as AGREE II and RIGHT in the process of guideline development and reporting.Screening awareness for high-risk groups of NAFLD and a sound early non-invasive diagnosis and evaluation system should be established.Multi-dimensional treatment plans for lifestyle, liver function and metabolic disorders should be provided for patients NAFLD .

Abstract：
The purpose of this paper is to investigate the chemical constituents of Potentilla kleiniana and their anti-inflammatory activity. The 60% ethanol extract of P. kleiniana were isolated by D-101 macroporous adsorptive resins, silica gel, Toyopearl HW-40F and other methods, and their chemical structures were elucidated on the basis of NMR and HR-ESI-MS analysis. Meanwhile, the anti-inflammatory activity of the compounds was evaluated by mouse macrophage (RAW 264.7) inflammatory model induced by lipopolysaccharide (LPS) in vitro. The results were as follows: (1) Fifteen compounds were isolated and identified from P. kleiniana as 2- (heptadecanoyloxy)propane-1,3-diyl distearate (1), 9,12,13-trihydroxy-10,15-octadecadienoic acid (2), methyl-9,12,13-trihydroxyoctadeca-10,15-dienoate (3), 2,2'-oxybis(1,4-di-tert-butylbenzene) (4), emodin (5), chrysophanol (6), (6R,9R)-3-oxo-α-ionol-9-O-β-D-glucopyranoside (7), neoandrographolide (8), methyl-α-D-fructofuranosides (9), 1-O-β-D-fructofuranosyl-α-D-allopyranos (10), p-coumaric acid (11), cesternosides A (12), koaburaside (13), orientin (14), isoorientin (15). Compounds 1-15 were obtained from Potentilla genus for the first time. (2) The anti-inflammatory test results showed that compounds 1-3, 8, and 11-15 had moderate inhibitory activities on NO production, and the inhibition rate of 8 was 72.5% at the concentrations of 25 μmol·L-1. In conclusion, the study enriches the phytochemical information of P. kleiniana, and clarifies that fatty acid derivatives, phenolic components and diterpenoids are anti-inflammatory active components, which provide a theoretical basis for further exploitation of P. kleiniana.

Abstract： Considering the performance deterioration of orthogonal frequency division multiplexing communication (OFDM) system due to narrowband interference (NBI) , this paper employed deep learning into NBI mitigation of OFDM systems and proposed two structures with convolutional neural network (CNN) . These two structures firstly pre-processed the received data in receiver, then adopted CNN to exploit the interference estimation in time domain. Finally the impact of NBI was removed from received signal. The simulation results demonstrate that the two systems can learn the interference effectively and improve system performance.

Abstract：本试验旨在研究仔猪出生后10~20 d，早期断奶仔猪小肠谷氨酸转运载体基因表达情况与哺乳仔猪的差异。试验分别从40头不同母猪的仔猪中各选出体重相近，10日龄的“杜×长×大”三元杂交仔猪1头，共40头仔猪，随机不配对分为2组，每组20头仔猪，对照组（哺乳组）为哺乳仔猪，随母猪喂养；试验组（断奶组）为断奶仔猪，隔离断奶饲养；试验期10 d。饲养结束，每组随机取12只仔猪，宰杀取空肠和回肠，测定谷氨酸转运载体兴奋性氨基酸转运载体1（EAAC1）蛋白质表达情况和游离氨基酸含量。结果显示，断奶显著降低了仔猪空肠和回肠EAAC1（57和73 ku）及其相关蛋白谷氨酸转运联合蛋白（GTRAP3-18）（50 ku）的蛋白质和基因表达量（P<0.05）。断奶提高了仔猪空肠游离谷氨酸和总氨基酸含量，却降低了仔猪回肠游离谷氨酸和总氨基酸含量，差异显著（P<0.05）。结果提示，早期断奶降低EAAC1和GTRAP3-18的蛋白质含量，这可能与早期断奶仔猪遭受营养谷氨酸缺乏导致的肠道氨基酸吸收转运障碍有关。
