Abstract	As the largest green macroalgal bloom in the Yellow Sea of China, the overgrowth and degradation of Ulva prolifera ( U . prolifera ) have a harmful effect on marine organisms and the aquaculture industry. However, the regulation mechanism of U. prolifera stress on the antioxidant capacity and inflammatory response of marine fish is still not completely understood. A 15-day exposure experiment was conducted to evaluate the effects of U. prolifera stress on the antioxidant capacity and inflammatory response of the Japanese flounder ( Paralichthys olivaceus ) (283.11 ± 6.45 g). The results showed that U . prolifera stress significantly decreased their survival rate. Serum total antioxidant capacity (T-AOC) and non-specific immune-related enzyme activities were significantly impacted under U . prolifera conditions. Moreover, U . prolifera stress significantly decreased T-AOC, superoxide dismutase (SOD) activity, and catalase (CAT) activities in the liver, while malondialdehyde (MDA) contents were significantly increased. Similarly, antioxidant-related gene ( cat , nrf2, and keap1 ) expressions were synchronously downregulated in the liver under U . prolifera stress. Furthermore, U . prolifera stress significantly upregulated pro-inflammatory gene ( tnf-α , il-1β , ifn-γ , and p65 ) expressions and the phosphorylation levels of the p38 and JNK MAPK pathways in the head kidney. In addition, endoplasmic reticulum (ER) stress-related gene and protein expressions were also upregulated in the head kidney. Overall, these results revealed that U. prolifera stress suppressed the antioxidant capacity and induced an inflammatory response in the Japanese flounder. This study could advance the understanding of the adverse effects of U . prolifera stress on marine benthic fish and promote the sustainable development of aquaculture.

Abstract	The remote sensing ecological index (RSEI) has been widely used in the rapid monitoring and evaluation of the regional ecological environment; however, the research on the main factors that cause changes in RSEI and the impact of human activities in the mining area on RSEI is not often explored. To this end, this paper selected the Landsat (TM/OLI) series of remote sensing images from 1986 to 2022; extracted the four important indicators of the normalized difference vegetation index (NDVI), the wetness component of the tasseled cap transformation (WET), normalized difference built-up and soil index (NDBSI), and land surface temperature (LST); calculated the remote sensing ecological index (RSEI) based on the principal component analysis method; monitored and evaluated the ecological environment changes in the Shendong Mining Area for a period of 36 years; and analyzed the driving forces that cause these ecological environment changes. The results show the following: (1) The ecological status of the study area has shown an overall upward trend during the 1986–2022 period. (2) From 1986 to 2022, the area of RSEI with a grade of 0.4–0.6 increased by 1142.74 km 2 , that with a grade of 0.6–0.8 increased by 124.09 km 2 , and that with a grade of 0.8–1.0 increased by 0.73 km 2 . (3) In the past 36 years, the proportion of RSEI with a positive grade difference was 97.52%, and the proportion of regions with a negative grade difference was 6.20%. (4) Rainfall is the main factor that causes changes in the regional ecological environment. By analyzing the main driving factors of ecological environment change and the relationship between human activities and RSEI, reference can be provided for the formulation of environmental protection policies and environmental planning in mining areas.

Abstract	Aiming at the problem that the current research is not suitable for the evaluation of the surface ecological environmental quality in a small-scale coal mining subsidence area, a model combining the hierarchical method and the weighted method was constructed to realize the comprehensive evaluation of the surface ecological environmental quality in a small-scale subsidence area. The results showed that the change in the water and soil environment caused by coal mining subsidence was the main factor affecting the quality of the ecological environment in the subsidence area; the evaluation results in the control area and uniform subsidence area were of grade III, which was at the “general” level, and the evaluation results in the non-uniform subsidence area were of grade VI, which was at the “poor” level. Coal mining subsidence has a great impact on the quality of ecological environment in a non-uniform subsidence area.

Abstract	Massive macroalgae blooms, primarily caused by the overgrowth of Ulva prolifera ( U. prolifera ) in the Yellow Sea of China, pose a severe risk to both marine organisms and the aquaculture industry. This study’s aim was to evaluate the impact of U. prolifera degradation on the growth performance and antioxidant capacity of Japanese flounder ( Paralichthys olivaceus ) and select some potential Japanese flounder families (labeled 2101–2108, established by crossbreeding) tolerating U. prolifera degradation conditions. Thus, a 60-day U. prolifera exposure experiment was conducted. The results showed that the contents of Na, K, Mg, and Fe elements in the U . prolifera degradation water were significantly increased. The specific growth rate and survival rate of flounder were significantly decreased under the U. prolifera degradation condition, while the 2101 and 2103 flounder families showed a better growth performance compared with the positive control (PC) group. Moreover, the results showed that activities of total antioxidant capacity (T-AOC), transaminases, and alkaline phosphatase (AKP) in serum were significantly decreased, while the 2103 flounder family showed higher activities. Furthermore, U. prolifera degradation significantly increased superoxide dismutase (SOD) activity and glutathione (GSH) content while decreasing catalase (CAT) activity and malondialdehyde (MDA) content in the liver. Specifically, SOD and CAT activities of the 2103 flounder family were higher than the 2101 flounder family and PC group. In addition, the gill SOD and CAT activities of the 2103 flounder family were significantly higher than the PC group. Similarly, the antioxidant-related gene ( sod and cat ) expressions were synchronously upregulated or downregulated in the liver and gills in response to U. prolifera degradation. These results revealed that U. prolifera degradation decreased the growth performance and influenced the antioxidant capacity of Japanese flounder, while the 2103 flounder family had better advantages in the U. ...

Abstract	Background: The traditional Chinese dentistry classroom teaching model focuses on the instruction of knowledge details, but less on the frameworks and learners' motivation. Here, we introduced a combination of mind mapping and PBL instruction (MBL)into the prosthodontics course for Chinese dental students. This study aimed to evaluate the effectiveness and efficiency of MBL in prosthodontics and make observations from the students' perspectives, based on their response with the learning process. Methods: We prospectively enrolled 56 fourth-year undergraduates of stomatology, and these participants were randomly allocated into either the combined mind map teaching group (MBL) or the problem-based learning group (PBL) to attend the prosthodontics course. An anonymous questionnaire was also administered to both groups to evaluate the students' perceptions and experiences, using closed and open-ended items. Data were analyzed using descriptive statistics and thematic analysis. Results: The students' responses to closed items indicate their experience in PBL and MBL to be positive, including increased motivation, improved memory of knowledge, enhanced discipline connection and raised teamwork, with fairly higher ratings for the MBL group. However, the tutor-guided competence scores including the memory and framework part, were significantly higher for MBL group than PBL group (two-way ANOVA, p < 0.01, p < 0.001, respectively). Meanwhile, the self-perceived competence scores including the motivation, framework and teamwork part, were significantly higher for MBL group than PBL group (two-way ANOVA, p < 0.01, p < 0.001, p < 0.05, respectively). Conclusion: Our findings suggest that MBL teaching approach can help in integration of knowledge structure and enhance clinical reasoning. MBL is an effective and well-organized method in prosthodontics course for dental students.

Abstract	Chinese tongue sole (Cynoglossus semilaevis) is a flatfish species unique to Northeast Asia, exhibiting the typical female-biased sexual size dimorphism (SSD). To explore the possible regulatory roles of non-coding RNAs (ncRNAs) on this phenomenon, whole transcriptomic analysis was performed by using female, male, and pseudomale C. semilaevis to identify differentially expressed (DE) long ncRNAs (DE lncRNAs), microRNA (DE miRNAs), and differentially expressed genes (DEGs) from the brain, gonad, liver, and muscle tissues. Most of them were concentrated in the gonad and muscle, and the gene expression patterns of pseudomale individuals were similar to male individuals. The association of DE lncRNAs and target messenger RNAs (mRNAs) was predicted based on antisense, cis-, and trans-regulatory mechanisms, with enriched protein digestion and absorption, cyclic adenosine monophosphate (cAMP) signaling pathway, sulfur metabolism, cell cycle, and splicesome (p < 0.05). Furthermore, weighted gene co-expression network analysis (WGCNA) was employed to cluster the expression patterns of DE lncRNA, and two modules (greenyellow and blue) had the highest positive and negative correlations with growth traits, respectively. Importantly, the female-biased expression in the greenyellow module and the male- and pseudomale-biased expression in the blue module were observed in the gonad. The target gene analysis for DE miRNA revealed 3,034 mRNA-miRNA pairs with the opposite expression patterns. Finally, the lncRNA-miRNA-mRNA network, including 385 DE lncRNAs, 138 DE miRNAs, and 456 DEGs, was constructed. Among which, 78 DE lncRNAs, 12 DE miRNAs, and 13 DEGs involved in cell growth and death pathway were related to the SSD of C. semilaevis. This study described the lncRNA-miRNA-mRNA regulatory network in the SSD of C. semilaevis for the first time. The functional prediction analysis suggested that these DE lncRNAs and DE miRNAs might be involved in flatfish SSD by regulating several potential growth-related pathways (e.g., cell ...

Abstract	Coal mining subsidence leads to reductions in soil fertility. In order to improve soil physical and chemical properties and to promote vegetation restoration, a nitrogen-fixing bacterium named S1 was isolated from the coal mining subsidence area in the Shendong mining area, and a zeolite-immobilized nitrogen-fixing bacterium was studied to improve the soil in the subsidence area. The results show that the immobilized nitrogen-fixing bacteria can significantly improve the ammonium nitrogen and nitrate nitrogen of soil by 50 times and 0.6 times, respectively, at 20 days, and it can also improve organic matter. In pot experiments, it was found that immobilized microorganisms can improve germination rate, plant height and the dry and fresh weight of maize. The results of the above soil culture tests and pot experiments were then compared and analyzed. It was found that plants made obvious use of soil ammonium nitrogen and nitrate nitrogen, and planting the plants was conducive to increases in soil organic matter.

Abstract	In this paper, the open-pit coal mine in semi-arid grassland was taken as the research object. The water samples of the open-pit coal mine and its surrounding areas were collected and the hydrochemical parameters were detected. The temporal and spatial distribution characteristics of the parameters such as pH, electrical conductivity, and dissolved oxygen in the groundwater were studied. The results showed that the groundwater in the study area was alkaline and brackish water. Climate factors might have a certain impact on the pH, conductivity, and dissolved oxygen of groundwater. The pH value of groundwater in the mining area was higher than that in the surrounding pastoral area, while the conductivity value of the mining area was between the pastoral area in the west and the Xilin river area in the east. The parameters of pH, conductivity and total dissolved solids of the four monitoring wells around the mining area showed a slow change or stable phenomenon in the vertical direction with the increase of groundwater depth. This study is of great significance to understand the characteristics of groundwater chemistry in mining areas and the rational development and utilization of groundwater resources.

Abstract	Sexual size dimorphism (SSD) is the difference in segments or body size between sexes prevalent in various species. Understanding the genetic architecture of SSD has remained a significant challenge owing to the complexity of growth mechanisms and the sexual influences among species. The Chinese tongue sole (Cynoglossus semilaevis), which exhibits a female-biased SSD and sex reversal from female to pseudomale, is an ideal model for exploring SSD mechanism at the molecular level. The present study aimed to integrate transcriptome and methylome analysis to unravel the genetic and epigenetic changes in female, male, and pseudomale C. semilaevis. The somatotropic and reproductive tissues (brain, liver, gonad, and muscle) transcriptomes were characterized by RNA-seq technology. Transcriptomic analysis unravelled numerous differentially expressed genes (DEGs) involved in cell growth and death-related pathways. The gonad and muscle methylomes were further employed for screening differentially methylated genes (DMGs). Relatively higher DNA methylation levels were observed in the male and pseudomale individuals. In detail, hypermethylation of the chromosome W was pronounced in the pseudomale group than in the female group. Furthermore, weighted gene co-expression network analysis showed that turquoise and brown modules positively and negatively correlated with the female-biased SSD, respectively. A combined analysis of the module genes and DMGs revealed the female-biased mRNA transcripts and hypomethylated levels in the upstream and downstream regions across the cell cycle-related genes. Moreover, the male and pseudomale-biased gene expression in the hippo signaling pathway were positively correlated with their hypermethylation levels in the gene body. These findings implied that the activation of the cell cycle and the inhibition of the hippo signaling pathway were implicated in C. semilaevis female-biased SSD. In addition, the dynamic expression pattern of the epigenetic regulatory factors, including dnmt1, dnmt3a, ...

Abstract	Aim. To examine the potential of Pudilan Keyanning toothpaste (PKT) to treat minor aphthous ulcers (MiAU). Method. A double-blind clinical trial was conducted in which 80 volunteers were randomly assigned to the PKT group (N=40) or the control group (N=40). The control group used a placebo toothpaste containing no Pudilan extract. At baseline, after 3 days, and after 6 days the following parameters were recorded for the target ulcers: healing rate, healing period, pain (visual analogue scale, VAS), areas of the target ulcerated lesions, degree of exudation, and hyperemia. Results. At the end of the study, the healing rate in the PKT group was 80%, compared to 50% in the control group (p<0.05). At day 6, the VAS scores, ulcer area, degree of exudation, and hyperemia were significantly different between the two groups, with better performance observed in the PKT group (p<0.05). Conclusion. PKT toothpaste appears to promote effective healing of MiAU.
