Low-light stress is known to have a significant impact on pumpkin yield in greenhouse conditions, it is crucial to understand the characteristics of low-light tolerance and identify resistant germplasm resources. In this study, four pumpkins (Cucurbita moschata) varieties were used, including three inbred lines (10–32, NY-1, and JB-1) and one hybrid line (NY-1×JB-1). Various low-light treatments (T0, no shade; T40, 40% shading; T80, 80% shading) were set, to explore their effects on morphology, photosynthetic characteristics, osmotic regulation substance content, and antioxidant enzyme activity in pumpkin seedling leaves. In the results, seedlings of inbred lines 10–32 and JB-1, as well as hybrid NY-1×JB-1, exhibited low-light resistance with shading rate increases. The maximum photochemical quantum yield of photosystem II (Fv/Fm) of all varieties decreased under low-light stress. Catalase (CAT) activity initially increased and then decreased, while superoxide dismutase (SOD) activity showed the opposite trend. Peroxidase (POD) activity gradually increased in 10–32, JB-1, and NY-1×JB-1, with JB-1 showing a significant increase at T80, and NY-1 displaying an initial decrease followed by an increase. Noteablely, the soluble proline (Pro) content decreased in 10–32, NY-1, and NY-1×JB-1. Significant differences in malondialdehyde (MDA) content were observed among the seedlings of four varieties. The MDA contents increased in 10–32 and JB-1 under T0 and T40, while showed no significant change in NY-1. The MDA content at T80 significantly decreased in NY-1, and first decreased and then significantly increased in NY-1×B-1. The soluble sugar content in 10–32 remained unchanged between T0 and T40, but significantly increased at T80. While in JB-1 and NY-1, it initially increased then decreased with increasing shading rate. The trend in NY-1×JB-1 was opposite to that of JB-1 and NY-1, with initially decreased followed by a significant increase. In conclusion, morphological characteristics associated with low-light tolerance can serve as reference indices for breeding low-light tolerance pumpkins. These parameters can be used as reference indices to assess pumpkin resistance to low-light stress.

This study focuses on the remediation of chromium (Cr), a heavy metal, in soil using substrate materials synthesized from plant roots, stems, leaves, and microbes. Corn was chosen as the source material for biochar production through high-temperature pyrolysis of corn roots, stems, and leaves. The biochar was then modified with an iron solution, and microbial adsorption was employed to remediate heavy metal Cr in the soil. The study involved physical and infrared analyses of the substrate materials and experiments to determine the adsorption contribution of different pH conditions, sites, and substrate materials to metal Cr. The effectiveness of plant roots, stems, leaves, and microbial combinations in remediating soil heavy metal pollution was verified. The experimental results demonstrate a decrease in the Zeta potential values of both materials as the pH increases. Moreover, as pH gradually increases, the form of Cr ions changes, and the reproductive ability of microbes weakens. The substrate materials exhibit a notable increase in negative charge, leading to enhanced repulsion towards Cr, which impacts their adsorption performance. At neutral pH, the adsorption capacity of the substrate materials for Cr is enhanced. The contribution rate of the composite substrate materials in the adsorption process is 6.78%, while that of microbial organisms is 56.45%, significantly higher than that of Fe-CBC. The main reason is that microbial adsorption activity for Cr is enhanced under higher pH conditions, with the contribution rate of microbial organisms continuing to increase significantly at a pH of 9.

This study investigates the impact and mechanisms of traditional Chinese medicine (TCM) intervention in patients with schizophrenia. In animal experiments, a total of 48 rats were randomly divided into four groups: control group (CG), model group (MG), Albizia flower flavonoid group (AFFG), and clozapine group (CLG). Each group consisted of 12 rats. After treatment, MK-801 was administered to the MG, AFFG, and CLG to establish schizophrenia rat models, while the CG received physiological saline. Cognitive abilities, hippocampal pathology, and protein expression were evaluated, and the expression levels of c-fos, cleaved Caspase-3, Bcl-2, and Bax were determined. In clinical trials, the study included 82 patients with schizophrenia treated at our hospital from February 2022 to February 2023. They were divided into the observation group (OG) and the experimental group (EG), with 41 cases in each group. The EG received aripiprazole and self-formulated TCM decoction, while the OG received aripiprazole. The PANSS scores and quality of life levels were compared. The results revealed impaired cognition, altered protein expression, and increased pathology in the MG compared to the CG. The AFFG and CLG exhibited enhanced cognition, improved protein expression, and reduced pathology when compared to the MG. Clinical findings demonstrated significantly lower PANSS scores and improved quality of life in the EG compared to the OG. In conclusion, Albizia flower flavonoids effectively modulated protein expression, ameliorated cognitive dysfunction, and reduced pathology. Additionally, the decoction decoction enhanced cognition and quality of life in patients with schizophrenia, suggesting promising clinical applications.

This study investigates the pharmacological properties of Danshen-Chuanxiongqin Injection and the impact of an evidence-based nursing model based on an innovative diffusion theory framework on neurological function in elderly patients with acute ischemic stroke. The stability of the injection was assessed via ultra-high-performance liquid chromatography coupled with quadrupole/orbitrap high-resolution mass spectrometry. The pharmacological properties of the injection were evaluated in three groups of rats: Group A (Cold coagulation and blood stasis), Group B (Blood stasis with sthenia), and Group C (Normal control). Groups A and B were further divided into subgroups receiving either physiological saline or the injection, followed by an analysis of hemorheological parameters. 200 elderly patients with acute ischemic stroke were divided into two groups: a control group (evidence-based nursing model based on the innovative diffusion theory framework) and an observation group (Danshen-Chuanxiongqin Injection+evidence-based nursing model based on the innovative diffusion theory framework). Medication quality was confirmed using SPSS 26.0. In animal experiments, Group B displayed improved hemorheology, adverse drug reaction, and thyroidstimulating hormone levels (P < 0.05). The observation group exhibited reduced post-treatment plasma renin activity, angiotensin II, aldosterone, and norepinephrine. At the treatment end and 6-month follow-up, the observation group showed significantly improved neurological function (P < 0.05). The injection demonstrated stable pharmacological properties with a cooling effect, effectively treating blood stasis with sthenia-related symptoms. The evidence-based nursing model with the innovative diffusion theory framework effectively enhanced neurological function, neuroendocrine hormones, clinical efficacy, and safety in elderly patients with acute ischemic stroke. This approach holds promise for further implementation and promotion.

Using waste plastic syngas to prepare carbon nanotubes (CNTs) and hydrogen-rich gas is a clean and efficient recycling method for waste plastics, and it is very important to find out how to improve its yield and quality. In this work, CNTs and hydrogen-rich gas were prepared by LaNiO3 perovskitetype catalysts from waste plastic syngas model compound in laboratory. The LaNiO3 catalysts, carbon nanotubes and gas fractions produced at different temperatures were characterized and compared with the supported catalyst Ni/ZSM-5. The main conclusions were as follows: 650 °C catalytic temperature had maximum carbon nanotubes yield of 5.84 gCNTs/gCatalyst and H2 content of 44 Vol.%, which was 4.44 times the carbon nanotubes yield from the Ni/ZSM-5 catalyst at the same temperature case. A bottom growth pattern of carbon nanotubes produced on the LaNiO3 catalyst was observed by high resolution transmission electron microscopy (HRTEM). The X-ray crystal diffractometer (XRD) analysis revealed that the interaction force between Ni and the carrier was stronger in LaNiO3 than that of the Ni/ZSM-5 catalyst, resulting in two different growth patterns of carbon nanotubes. The present experiments probe that the LaNiO3 catalysts have a greater prospect of application in the preparation of CNTs and hydrogen-rich gas from waste plastic syngas.

The BrassinaZole Resistant (BZR) gene family mediates the signal transduction of brassinolide, which is vital in regulating vegetative and reproductive growth of plants. In this research, a comprehensive analysis of all candidate BrBZR genes in Chinese cabbage (Brassica rapa ssp. pekinensis) was conducted using bioinformatics methods, including protein physicochemical properties, evolutionary relationship, gene structure, and conserved domains. Additionally, these candidate genes’ expression patterns during flowering development were analyzed utilizing transcriptome data, and key genes that regulate flowering of Chinese cabbage were screened. In the results, 14 BrBZR genes were identified, with coding sequence (CDS) lengths of 460–1162 bp, and encoding proteins of 152–386 amino acids. The majority of BrBZRs had a highly conserved motif 1 as well as numerous regulatory elements associated with hormone and abiotic stress responses. Transcriptome sequencing showed that 12 BrBZRs were expressed during the flowering development, among which BrBES1.1 and BrBES1.2 were highly expressed, with FPKM ranges of 61.78–99.91 and 43.71–76.69, respectively. Their expression was upregulated during vernalization and flower bud differentiation, suggesting that they may play a key role in regulating the flowering process of Chinese cabbage. Overall, our study provides comprehensive insights into the BrBZR gene family, and has important implications for the further elucidation of the mechanisms that regulate flower development in Chinese cabbage and potentially other related Brassica species.

Mulberry (Morus spp.), a flowering plant in the Moraceae family, is known for the edible fruit, and mulberry leaves have various applications. This experiment utilized ultra-high performance liquid chromatography-quadrupole time of flight mass spectrometry (UPLC-Q-TOF-MS) and Progenesis QI software to rapidly identify secondary metabolites in the leaves of Morus nigra L. and Morus alba L.. Orthogonal partial least squares discriminant analysis (OPLS-DA), principal component analysis (PCA) and Hierarchical clustering analysis (HCA) were used to examine the dynamic changes and stage specificity of metabolites, particularly alkaloids, in M. nigra and M. alba leaves during seven primary growth stages. In results, the leaf samples from different growth stages uncovered a total of 182 metabolites from 13 distinct categories. M. nigra had significantly higher levels of metabolites than those in M. alba, according to differences in leaf metabolite accumulation patterns. Multiple statistical analyses revealed that the metabolome of M. nigra and M. alba leaves exhibited a significant interspecific and developmental specific accumulation patterns, with most DNJ alkaloids having the highest content in M. nigra leaves. In different growth stages, the metabolites of M. nigra leaves showed significant stage specificity. During the development stage of small fruit stage, obvious changes occurred in the chemical composition of M. nigra leaves, with a significant increase in DNJ alkaloid metabolites. Overall, this study provides a theoretical reference for the comprehensive development and sustainable utilization of M. nigra resources in Xinjiang.

Nanocellulose fibers (NCFs) were converted to cellulose nanocrystals (CNCs) and then modified with diethylenetriamine pentaacetic acid (DTPA) to form modified CNCs (DTPA–CNCs), which were investigated as adsorbents for removing Cu2+ from aqueous solution. The adsorption behavior was affected by pH, contact time, dosage and raw Cu2+ concentration. Langmuir model is the best method to fit the adsorption isotherm of experimental results. The optimal conditions for Cu2+ adsorption were 2 h at 35 °C and pH 3, the optimal adsorption capacity is 94.5 mg/g. These functional groups on the DTPA–CNCs provided enhanced adsorption capacity, compared with unmodified NCFs.

This study investigated the impact of various concentrations of NaCl stress treatment (0%, 0.1%, 0.2%, 0.3%, 0.4%) on the growth of one-year-old saplings of purple leaf barberry and glacier red leaf barberry. It also examined the impact on various physiological responses including plasma membrane permeability, antioxidant protective enzyme system, osmotic regulatory substance content, photosynthetic characteristics, ion content, and the ultrastructure of leaf cells using transmission electron microscopy. The goal was to determine the salt tolerance threshold and elucidate the physiological response mechanism to NaCl stress. The comprehensive assessment of salt tolerance in the two barberries was done using fuzzy membership functions. The results demonstrated that increasing concentrations of NaCl stress and longer treatment durations led to gradual decreases in sapling growth and increases in salt damage index. The salt tolerance thresholds were calculated to be 0.37% for purple leaf barberry and 0.33% for glacier red leaf barberry using the logistic curve equation. The activities of SOD and POD initially increased and then decreased in both barberries. Furthermore, MDA, free proline, and Na+ content gradually increased, while soluble protein content, chlorophyll content, net photosynthetic rate (Pn), K+ content, and K+/Na+ ratio gradually decreased. The purple leaf barberry displayed larger and deformed chloroplasts with significant separation of quality and wall, whereas the glacier red leaf barberry experienced a gradual decrease in chloroplast size and number until degradation. The membership function analysis revealed that purple leaf barberry exhibited superior resistance compared to glacier red leaf barberry.

Developing marginal lands to plant energy crops and then develop biomass-to-liquid fuels is an effective way to ease the energy crisis, promote greenhouse gas emission reduction, and protect the natural ecological environment. Taking Henan Province, China as a research object, the research obtained spatial distributions and areas of marginal lands in the province by processing remote-sensing data for land use using software ArcGIS. Marginal lands in Henan Province were classified into the first-class, second-class, and third-class ones by selecting key natural conditions including the soil thickness, slope, soil texture (sand volume fraction), accumulated temperature above 10 °C, organic matter content, and total annual precipitation as indices. The research showed that the total area of marginal lands in the province is 1.68×104 km2, including 0.62×104 km2 of first-class marginal lands, 0.83×104 km2 of second-class marginal lands, and 0.23×104 km2 of third-class marginal lands. Taking production of bioethanol with sugar grass as an example, 8.92×107 t of sugar grass can be harvested on the marginal lands in Henan Province, which can be converted into 5.80×106 t of bioethanol, equivalent to 6.96×106 t of standard coal. The research can provide reference for realizing energy structure optimization and consolidating energy security in Henan Province.
开发边际土地种植能源作物，进而发展生物质液化燃料，是缓解能源危机、促进温室气体减排、保护自然生态环境的有效途径。本研究以中国河南省为研究对象，通过使用 ArcGIS 软件处理土地利用遥感数据，获得了该省贫瘠土地的空间分布和面积。通过选取土壤厚度、坡度、土壤质地（沙体积分数）、10 ℃以上积温、有机质含量和年降水总量等关键自然条件作为指标，将河南省的边缘土地划分为一类地、二类地和三类地。研究结果表明，全省边际土地总面积为 1.68×104 平方公里，其中一级边际土地面积为 0.62×104 平方公里，二级边际土地面积为 0.83×104 平方公里，三级边际土地面积为 0.23×104 平方公里。以糖料草生产生物乙醇为例，河南省边缘土地可收获糖料草 8.92×107 t，可转化为 5.80×106 t 生物乙醇，相当于 6.96×106 t 标准煤。该研究可为河南省实现能源结构优化、巩固能源安全提供参考。
