Abstract
OBJECTIVE To determine and compare the serum metabolites in missed abortion versus normal early pregnancy using ultra-high-performance liquid chromatography and tandem time-of-flight mass spectrometry, and to determine how these metabolites can be used to predict the potential biomarkers and possible metabolic pathways of a missed abortion. METHODS The serum of patients with a missed abortion was used as the experimental group and the serum of patients with an induced abortion during normal early pregnancy was used as the control group. Principal component analysis and orthogonal partial least square discriminant analysis were additionally used to observe the difference in metabolite distribution between the two groups. A variable weight value (variable importance in the projection; VIP) obtained from the orthogonal partial least squares discriminant analysis model more than 1 and P less than 0.05 were taken to indicate significant differences in metabolite screening. After this, enrichment analysis of the metabolic pathways of these metabolites was conducted using Fisher precise test in order to find the metabolic pathway with the highest correlation with the differential metabolites. RESULTS In total, 30 patients were included in the experimental group, with 30 patients in the control group. Fifty-five metabolites (VIP > 1, P < 0.05) with significant differences related to missed abortion were selected, among which 35 metabolites increased and 20 decreased in patients with a missed abortion. KEGG pathway enrichment analysis showed that the four metabolic pathways with the highest correlation were cholesterol metabolism, arginine biosynthesis, cell apoptosis, and the FoxO signaling pathway. CONCLUSION The missed abortion serum metabolites and changes in related metabolic pathways reported in this study provide a basis for the early prediction and diagnosis of a missed abortion.

Abstract
There is a growing focus on exploring dyadic interactions and outcomes between couples undergoing cervical cancer (CC). The purpose of this cross-sectional study was to figure out how dyadic communication influences both CC patients' and spouses' coping abilities. A sample of 286 CC dyads completed questionnaires assessing dyadic communication and dyadic coping. The actor-partner interdependence model was used to analyze the interaction effect between the dyads. Dyadic communication among cervical cancer (CC) patients has a predictive effect on their own negative dyadic coping (β = - 0.141, P = 0.034) and on their spouses' delegated dyadic coping (β = 0.133, P = 0.044). In contrast, dyadic communication among CC spouses is negatively associated with their own supportive dyadic coping (β = - 0.237, P < 0.001), delegated dyadic coping (β = - 0.156, P = 0.018), common dyadic coping (β = - 0.148, P = 0.026) and also with CC patients' supportive dyadic coping (β = - 0.153, P = 0.022). Dyadic communication between CC patients and their spouses affect their own and each other's dyadic coping. Exploring interventions focused on the CC couples' communication strategies to enhance their positive dyadic coping should be considered.

Abstract
The genus Apium, belonging to the family Apiaceae, comprises roughly 20 species. Only two species, Apium graveolens and Apium leptophyllum, are available in China and are both rich in nutrients and have favorable medicinal properties. However, the lack of genomic data has severely constrained the study of genetics and evolution in Apium plants. In this study, Illumina NovaSeq 6000 and Nanopore sequencing platforms were employed to identify the mitochondrial genomes of A. graveolens and A. leptophyllum. The complete lengths of the mitochondrial genomes of A. graveolens and A. leptophyllum were 263,017 bp and 260,164 bp, respectively, and contained 39 and 36 protein-coding genes, five and six rRNA genes, and 19 and 20 tRNA genes. Consistent with most angiosperms, both A. graveolens and A. leptophyllum showed a preference for codons encoding leucine (Leu). In the mitochondrial genome of A. graveolens, 335 SSRs were detected, which is higher than the 196 SSRs found in the mitochondrial genome of A. leptophyllum. Studies have shown that the most common RNA editing type is C-to-U, but, in our study, both A. graveolens and A. leptophyllum exhibited the U-C editing type. Furthermore, the transfer of the mitochondrial genomes of A. graveolens and A. leptophyllum into the chloroplast genomes revealed homologous sequences, accounting for 8.14% and 4.89% of the mitochondrial genome, respectively. Lastly, in comparing the mitochondrial genomes of 29 species, it was found that A. graveolens, A. leptophyllum, and Daucus carota form a sister group with a support rate of 100%. Overall, this investigation furnishes extensive insights into the mitochondrial genomes of A. graveolens and A. leptophyllum, thereby enhancing comprehension of the traits and evolutionary patterns within the Apium genus. Additionally, it offers supplementary data for evolutionary and comparative genomic analyses of other species within the Apiaceae family.

Abstract
Selenium (Se) is a trace element that plays a crucial role in metabolism; a lack of selenium reduces the body's resistance and immunity, as well as causes other physiological problems. In this study, we aim to identify favorable conditions for improving organic selenium production. The functional microbe Monascus purpureus, which is widely used in food production, was employed to optimize selenium-enriched culture conditions, and its growth mode and selenium-enriched features were investigated. Spectrophotometry, inductively coupled plasma optical emission spectrometry (ICP-OES), and HPLC (High-Performance Liquid Chromatography) were used to determine the effects of various doses of sodium selenite on the selenium content, growth, and metabolism of M. purpureus, as well as the conversion rate of organic selenium. The best culture parameters for selenium-rich M. purpureus included 7.5 mg/100 mL of selenium content in the culture medium, a pH value of 6.8, a culture temperature of 30 °C, and a rotation speed of 180 rpm. Under ideal circumstances, the mycelia had a maximum selenium concentration of approximately 239.17 mg/kg, with organic selenium accounting for 93.45%, monacoline K production reaching 70.264 mg/L, and a secondary utilization rate of external selenium of 22.99%. This study revealed a novel biological route-selenium-rich M. purpureus fermentation-for converting inorganic selenium into organic selenium.

Abstract
Plant hormones are important for regulating growth, development, and plant-pathogen interactions. Some of them are inhibitory to growth of fungal pathogens but the underlying mechanism is not clear. In this study, we found that hyphal growth of Fusarium graminearum was significantly reduced by high concentrations of IAA and its metabolically stable analogue 2,4-dichlorophenoxyacetic acid (2,4-D). Besides inhibitory effects on growth rate, treatments with 2,4-D also caused significant reduction in conidiation, conidium germination, and germ tube growth. Treatments with 2,4-D had no obvious effect on sexual reproduction but significantly reduced TRI gene expression, toxisome formation, and DON production. More importantly, treatments with 2,4-D were inhibitory to infection structure formation and pathogenesis at concentrations higher than 100 µM. The presence of 1000 µM 2,4-D almost completely inhibited plant infection and invasive growth. In F. graminearum, 2,4-D induced ROS accumulation and FgHog1 activation but reduced the phosphorylation level of Gpmk1 MAP kinase. Metabolomics analysis showed that the accumulation of a number of metabolites such as glycerol and arabitol was increased by 2,4-D treatment in the wild type but not in the Fghog1 mutant. Transformants expressing the dominant active FgPBS2S451D T455D allele were less sensitive to 2,4-D and had elevated levels of intracellular glycerol and arabitol induced by 2,4-D in PH-1. Taken together, our results showed that treatments with 2,4-D interfere with two important MAP kinase pathways and are inhibitory to hyphal growth, DON biosynthesis, and plant infection in F. graminearum.

Abstract
Mahuang-Fuzi-Xixin Decoction (MFXD) is widely used in the treatment of asthma, however, the functional components in the decoction targeting beta2-adrenoceptor (β2 -AR) remain unclear. Herein, we immobilized the haloalkane dehalogenase (Halo)-tagged β2 -AR on the 6-chlorocaproic acid-modified microspheres. Using the affinity stationary phase, the interactions of four ligands with the receptor were analyzed by stepwise frontal analysis. The association constants were (4.75±0.28)×104 M-1 for salbutamol, (2.93±0.15)×104 M-1 for terbutaline, (1.23±0.03)×104 M-1 for methoxyphenamine, (5.67±0.38)×104 M-1 for clorprenaline at high-affinity binding site, and (2.73±0.05)×103 M-1 at low-affinity binding site. These association constants showed the same rank order as the radioligand binding assay, demonstrating that immobilized β2 -AR had capacity to screen bioactive compounds binding to the receptor while stepwise frontal analysis could predict their binding affinities. Application of the immobilized receptor in analysis of MFXD by chromatographic method revealed that ephedrine, aconifine, karakoline, and chasmanine were the bioactive compounds targeting β2 -AR. Among them, ephedrine and chasmanine exhibited association constants of (2.94±0.02)×104 M-1 and (4.60±0.15)×104 M-1 to the receptor by stepwise frontal analysis. Molecular docking analysis demonstrated that ephedrine, chasmanine, and the other two compounds interact with β2 -AR through the same pocket involving the key amino acids such as Asn312, Asp113, Phe289, Trp286, Tyr316, and Val114. As such, we reasoned that the four compounds dominate the therapeutic effect of MFXD against asthma through β2 -AR mediating pathway. This work shed light on the potential of immobilized β2 -AR for drug discovery and provided a valuable methodology for rapid screening.

Abstract
Although the treatment of liver cancer has made great progress, the mechanism of its occurrence is not completely clear. miR-155 plays an important regulatory role in tumorigenesis and development, including survival, proliferation, migration and invasion. However, the role and regulatory mechanism of miR-155 in liver cancer has rarely been reported. We analyzed miR-155 expression in liver cancer tissue samples and cell lines by qRT-PCR. The expression of miR-155 was measured by qRT-PCR before and after miR-155-mimic and sh-miR-155 transfection. CCK-8 and clonogenic assays were used to detect the proliferation of liver cancer cells. Cell scratch and invasion assays were used to detect migration and invasion. RNA-seq was used to detect the difference in RNA expression in liver cancer cells. SRPK1 expression was detected in liver cancer cells before and after transfection by qRT-PCR and western blotting. We observed that miR-155 was downregulated in liver cancer tissues compared with normal tissues. Furthermore, we demonstrated that liver cancer cell proliferation, migration and invasion are markedly suppressed by miR-155. Importantly, we also demonstrated that SRPK1 is directly regulated by miR-155 during the process of liver cancer cell proliferation and metastasis. Finally, the overexpression of miR-155 inhibits malignant biological behavior of human liver cancer cells. We report the abnormal expression of the miR-155 cluster in liver cancer cells, which inhibits cancer cell proliferation and metastasis. In addition, we identified SRPK1 as a target gene of miR-155 during the process of liver cancer cell proliferation and metastasis.
