ObjectiveThis study aims to explore and elucidate the possible mechanism of action of Shakuyakukanzoto (SKT) in improving ulcerative colitis (UC) in mice through regulating energy metabolism and polarization of macrophages. MethodsThe mouse UC model was constructed by administering 3% dextran sulfate sodium salt (DSS), and the mice were treated with SKT intragastrically. In addition, single-cell sequencing and enrichment of metabolic pathways against two datasets, GSE21157 and GSE210415, were conducted first. Second, the extraction and metabolomics of peritoneal macrophages from UC mice were verified. Then, the pathway of differentially abundant metabolite enrichment and the correlation of UC risk were analyzed depending on univariate Mendelian randomization of two samples weighted by standard inverse variance. Finally, the results were verified by qRT-PCR, Western blot, and flow cytometry. ResultsAccording to the HE staining results, SKT can significantly alleviate colon damage caused by DSS. Macrophages, NK cells, T cells, and more than 10 different types of cells, based on single-cell sequencing analysis, are detected in the intestinal wall. In the disease group, we can conclude that the activity of 49 macrophage metabolic pathways, mainly involved in energy metabolism, is significantly upregulated through a comparison of the two datasets. In energy metabolomics, 10 and 18 types of metabolites accompanied by significantly upregulated and downregulated differential expression were identified in the treatment group and the model group, as well as the model group and the blank group, respectively. Meanwhile, these differentially expressed metabolites present an obvious correlation with glycolysis and oxidative phosphorylation. Moreover, it can be inferred that glycolysis and the oxidative phosphorylation-related gene NDUFS1 (OR: 0.56, 95% CI: 0.48-0.98, P=0.000 068) are associated with a reduced risk of UC based on the univariate Mendelian randomization of two samples weighted based on standard inverse variance. By analyzing the difference in transcription levels between the two datasets, the transcription level of NDUFS1 in UC was decreased compared with that in the normal group. The results of qRT-PCR, Western blot, and flow cytometry indicate that SKT can promote the expression of the oxidative phosphorylation protein NDUFS1 in macrophages and inhibit the M1-type polarization of macrophages. Furthermore, knockdown/overexpression of NDUFS1 can affect the effect of SKT on M1-type polarization of macrophages. ConclusionBased on the results of this study, SKT inhibits macrophage polarization toward the M1 phenotype by regulating the level of the oxidatively phosphorylated protein NDUFS1 in macrophages; hence, UC is also relieved in mice. These conclusions not only reveal the therapeutic mechanism of SKT for UC but also provide a new theoretical basis for clinical application.

Background Individual monitoring of occupational external exposure is an essential part of the occupational health management of radiation workers, and is an important basis for the evaluation of individual absorbed dose and the diagnosis of occupational radiation diseases. Continuous participation of monitoring service providers in intercomparison is a fundamental quality assurance for routine monitoring, which can identify problems and improve them in time. Objective Taking the Laboratory of Radiation Protection in Shanghai Institute of Preventive Medicine as an example, to evaluate the performance of an individual occupational external dose monitoring system in the laboratory, identify influencing factors of the monitoring results, and provide a basis for improving the quality of daily monitoring by analyzing the process and results of a national intercomparison of individual dose monitoring. Methods According to the Testing criteria of personnel dosimetry performance for external exposure (GBZ 207-2016), and the relevant requirements of Class II (photon) inspection, a total of 20 groups of blind sample dosimeters were measured for four consecutive years from 2018 to 2021. The radiation energy source of each group was identified, and related personal dose equivalent Hp(10), the uncertainty of measurement results, and the deviation between the reported value and the reference value were calculated. The national intercomparison process and results of individual dose monitoring were also analyzed. Results The energy sources of the blind samples in the tested laboratory for four years were N100 or Cs-137. The reported dose values of the blind samples were 0.57-4.61 mSv, the combined uncertainties were 0.043-0.365 mSv, the expanded uncertainties (k=2) were 0.09-0.73 mSv, and the relative expanded uncertainties (k=2) were 13.8%-16.4%. The single-group performance ∣Pi∣ of 20 sets of blind samples in the four years was ≤0.10, the yearly comprehensive performance of 5 sets of blind samples was ≤0.10, and the yearly Q score of the test report was >15 points. The laboratory achieved excellent results in the national intercomparison of individual dose monitoring in four consecutive years, except the Q value not reaching full score. Conclusion The laboratory exhibits standardized data processing of individual dose monitoring, generates accurate and reliable results, and meets the requirements of relevant national standards; but it should continue to participate in the national intercomparison of individual dose monitoring, strengthen the angular response research of energy identified dosimeter, improve the monitoring ability of low-dose X-rays, analyze the key points of reducing the uncertainty of measurement results, and continuously improve the monitoring ability.

This paper aimed to explore the antidepressant effect of the essential oil from Schizonepeta tenuifolia Briq.(EOST) on the treatment of depression and its mechanism by using a combination of network pharmacology and the mouse model of lipopolysaccharide(LPS)-induced depression. The chemical components in EOST were identified using gas chromatography-mass spectrometer(GC-MS), and 12 active components were selected as the study objects. The targets related to EOST were obtained by Traditional Chinese Medicines Systems Pharmacology(TCMSP) and SwissTargetPrediction database. The targets related to depression were screened out through GeneCards, Therapeutic Target Database(TTD), and Online Mendelian Inheritance in Man(OMIM) database. The Venny 2.1 was applied to screen out the common targets of EOST and depression. The targets were imported into Cytoscape 3.7.2 to generate "drug-active component-diease-target" network diagram. The protein-protein interaction(PPI) network was constructed using STRING 11.5 database and Cytoscape 3.7.2, and the core targets were screened out. DAVID 6.8 database was used for Gene Ontology(GO) func-tional enrichment analysis and Kyoto Encyclopedia of Genes and Genomes(KEGG) pathway enrichment analysis, and subsequently the enrichment results were visualized through the bioinformatics platform. The mouse model of depression was induced by intraperitoneally injecting with LPS in mice. Before modeling, mice were administrated orally with EOST. The antidepressant effect of EOST was evalua-ted by tail suspension test(TST), forced swimming test(FST), and novelty suppressed feeding test(NSFT) after modeling. The content of interleukin(IL)-1β was determined by enzyme-linked immunosorbent assay(ELISA), and the protein expression levels of IL-1β and pro IL-1β in the hippocampus were determined by Western blot. There were 12 main components and 179 targets in EOAT, of which, 116 targets were related to depression, mainly involved in neuroactive ligand-receptor interaction, calcium signaling pathway, and cyclic adenosine monophosphate(cAMP) signaling pathway. Biological processes such as synaptic signal transduction, G-protein coupled receptor signaling pathway, and chemical synaptic transmission were involved. Molecular functions such as neurotransmitter receptor activity, RNA polymerase Ⅱ transcription factor activity, and heme binding were involved. In mice experiments, the results showed that EOST at 100 mg·kg~(-1) and 50 mg·kg~(-1) significantly shortened the immobility time in TST and FST as well as the feeding latency in NSFT compared with the model group, decreased the levels of serum IL-1β and NO, and reduced the protein expression levels of IL-1β and pro IL-1β in the hippocampus. In conclusion, EOST shows a good antidepressant effect in a multi-component, multi-target, and multi-pathway manner. The mechanism may be attributed to the fact that EOST can down-regulate the protein expression levels of IL-1β and pro IL-1β, decrease the release of inflammatory factors, and reduce neuroinflammation response.

Tuber rot has become a serious problem in the large-scale cultivation of Gastrodia elata. In this study, we compared the resistance of different ecotypes of G. elata to tuber rot by field experiments on the basis of the investigation of G. elata diseases. The histological observation and transcriptome analysis were conducted to reveal the resistance differences and the underlying mechanisms among different ecotypes. In the field, G. elata f. glauca had the highest incidence of tuber rot, followed by G. elata f. viridis, and G. elata f. elata and G. elata f. glauca×G. elata f. elata showed the lowest incidence. Tuber rot showcased obvious plant source specificity and mainly occurred in the buds and bottom of G. elata plants. After infection, the pathogen spread hyphae in host cortex cells, which can change the endophytic fungal community structure in the cortex and parenchyma of G. elata. G. elata f. glauca had thinner lytic layer and more sugar lumps in the parenchyma than G. elata f. elata. The transcription of genes involved in immune defense, enzyme synthesis, polysaccharide synthesis, carbohydrate transport and metabolism, hydroxylase activity, and aromatic compound synthesis had significant differences between G. elata f. glauca and G. elata f. elata. These findings suggested that the differences in resis-tance to tuber rot among different ecotypes of G. elata may be related to the varied gene expression patterns and secondary metabolites. This study provides basic data for the prevention and control of tuber rot and the improvement of planting technology for G. elata.

This study aims to explore the resource utilization of used fungus-growing materials produced in the cultivation of Gastrodia elata. To be specific, based on the production practice, this study investigated the recycling mechanism of used fungus-growing materials of G. elata by Phallus inpudicus. To screen edible fungi with wide adaptability, this study examined the allelopathic effects of Armillaria mellea secretions on P. impudicus and 6 kinds of large edible fungi and the activities of enzymes related to degradation of the used fungus-growing materials of G. elata. The results showed that P. impudicus can effectively degrade cellulose, hemicellulose, and lignin in used fungus-growing materials of G. elata. The cellulase activity of A. mellea was significantly higher than that of P. impudicus, and the activities of lignin peroxidase, polyphenol oxidase, and xylanase of P. impudicus were significantly higher than those of A. mellea, which was the important reason why A. mellea and P. impudicus used different parts and components of the used fungus-growing materials to absorb carbon sources and develop ecological niche differences. The growth of P. impudicus was significantly inhibited on the used fungus-growing materials of G. elata. The secretions of A. mellea had allelopathic effects on P. impudicus and other edible fungi, and the allelopathic effects were related to the concentration of allelopathy substances. The screening result showed that the growth and development of L. edodes and A. auricular were not significantly affected by 30% of A. mellea liquid, indicating that they had high resistance to the allelopathy of A. mellea. The results showed that the activities of extracellular lignin peroxidase, polyphenol oxidase, and xylanase of the two edible fungi were similar to those of P. impudicus, and the cellulase activity was higher than that of P. impudicus. This experiment can be further verified by small-scale production tests.

OBJECTIVE@#Moxibustion, a common therapy in traditional Chinese medicine, has potential benefits for treating decreased ovarian reserve (DOR). The present study investigates the protective effect of moxibustion in a rat model of DOR and explores the possible mechanisms.@*METHODS@#Sixty-four female Sprague-Dawley rats were randomly divided into four groups: control, DOR, moxibustion (MOX), and hormone replacement therapy (HRT). The DOR rat model was established by intragastric administration of 50 mg/kg Tripterygium glycoside suspension (TGS), once daily for 14 days. MOX and HRT treatments were given from the day TGS administration was initiated. The ovarian reserve function was evaluated by monitoring the estrus cycle, morphological changes in ovaries, levels of serum estradiol (E2), follicle-stimulating hormone (FSH), luteinizing hormone (LH), and anti-Mullerian hormone (AMH), pregnancy rate and embryo numbers. Terminal-deoxynucleotidyl transferase-mediated nick-end-labeling staining was used to identify ovarian granulosa cell apoptosis, while the protein and mRNA expressions of Bax, B-cell lymphoma-2 (Bcl-2), phosphatidylinositol 3-kinase (PI3K) and protein kinase B (AKT) in ovarian tissues were examined by immunohistochemistry, Western blot and quantitative reverse transcription-polymerase chain reaction.@*RESULTS@#Compared with the DOR group, MOX improved the disordered estrous cycle, promoted follicular growth, reduced the number of atresia follicles, increased the concentrations of serum E2 and AMH, and decreased serum FSH and LH concentrations. More importantly, the pregnancy rate and embryo numbers in DOR rats were both upregulated in the MOX treatment group, compared to the untreated DOR model. Further, we found that the MOX group had reduced apoptosis of ovarian granulosa cells, increased Bcl-2 expression and reduced expression of Bax. Furthermore, the PI3K/AKT signaling pathway was triggered by the moxibustion treatment.@*CONCLUSION@#Moxibustion improved ovarian function and suppressed apoptosis of ovarian granulosa cells in a rat model of DOR induced by TGS, and the mechanism may involve the PI3K/AKT signaling pathway.

OBJECTIVES@#To examine the association between duration of fever before intravenous immunoglobulin (IVIG) treatment and IVIG resistance in children with Kawasaki disease (KD).@*METHODS@#A retrospective analysis was performed on the medical data of 317 children with KD who were admitted from January 2018 to December 2020. According to the duration of fever before IVIG treatment, they were divided into two groups: short fever duration group (≤4 days) with 92 children and long fever duration group (>4 days) with 225 children. According to the presence or absence of IVIG resistance, each group was further divided into a drug-resistance group and a non-drug-resistance group. Baseline data and laboratory results were compared between groups. A multivariate logistic regression analysis was used to identify the influencing factors for IVIG resistance.@*RESULTS@#In the short fever duration group, 19 children (20.7%) had IVIG resistance and 5 children (5.4%) had coronary artery aneurysm, and in the long fever duration group, 22 children (9.8%) had IVIG resistance and 19 children (8.4%) had coronary artery aneurysm, suggesting that the short fever duration group had a significantly higher rate of IVIG resistance than the long fever duration group (P<0.05), while there was no significant difference in the incidence rate of coronary artery aneurysm between the two groups (P>0.05). In the short fever duration group, compared with the children without drug resistance, the children with drug resistance had a significantly lower level of blood sodium and significantly higher levels of procalcitonin, C-reactive protein, and N-terminal B-type natriuretic peptide before treatment (P<0.05). In the long fever duration group, the children with drug resistance had significantly lower levels of blood sodium and creatine kinase before treatment than those without drug resistance (P<0.05). The multivariate logistic regression analysis showed that a reduction in blood sodium level was associated with IVIG resistance in the long fever duration group (P<0.05).@*CONCLUSIONS@#IVIG resistance in children with KD varies with the duration of fever before treatment. A reduction in blood sodium is associated with IVIG resistance in KD children with a duration of fever of >4 days before treatment.

Objective:To analyze relationship between 13q14 deletion and prognosis in initial-treatment patients with multiple myeloma (MM).Methods:The follow-up data of 121 patients with newly diagnosed MM admitted to the First People's Hospital of Xiangtan City from January 2012 to December 2016 were collected and divided into deletion group ( n=39) and non deletion group ( n=82) according to the deletion of 13q14.The prognosis situations were compared among patients with different 13q14 deletion. Univariate analysis was performed for 3-year overall survival (OS) and progression free survival (PFS) in patients with MM. Results:As of the follow-up time, the 3-year OS rate, 3-year OS, 3-year PFS rate, 3-year PFS and median PFS were 71.90%(87/121), 5.8-36 months, 47.93%(58/121), 2.3-36 months and 34.8 months, respectively. The age, hypoproteinemia, high lactic dehydrogenase (LDH) and 13q14 deletion were independent influencing factors of OS ( P<0.05). The age, high LDH and 13q14 deletion were independent influencing factors of PFS ( P<0.05). The 3-year OS rate and 3-year PFS rate in 13q14 deletion group were 61.54%(24/39) and 25.64%(10/39), lower than those in non-deletion group ( P<0.05). Conclusions:The short-term prognosis is poor in initial-treatment MM patients with 13q14 deletion. Conducting risk stratified treatment for patients based on common influencing factors of OS and PFS is conducive to improving their prognosis.

We investigated the effect of methyl jasmonate (MeJA) on the content of asperosaponin VI and the expression of genes involved in its synthesis. Dipsacus aspero seedlings were treated with MeJA at different concentrations of 50, 100, 150, 200 and 300 μmol·L-1, and leaves and roots were sampled following treatment for 1, 3 and 5 days. The content of asperosaponin VI and superoxide anion in the roots, malondialdehyde (MDA) content in leaves and superoxide dismutase were determined. The results show that 150 μmol·L-1 MeJA significantly increased the accumulation of asperosaponin VI in roots. The content of asperosaponin VI was greatest after treatment for 3 days, and was 2.16 times higher than the control. After MeJA treatment, SOD activity decreased and MDA content increased in leaves. Moreover, superoxide anion content in roots increased. The expression of squalene epoxidase (DaSE1) and geranyl diphosphate synthase (DaGPS), key enzymes in the synthesis of asperosaponin VI, were up-regulated compared with the control group. These results indicate that an optimal concentration of 150 μmol·L-1 MeJA increases the accumulation of asperosaponin VI by up-regulating the expression of key enzymes involved in the synthesis of asperosaponin VI, which facilitates resistance to adversity stress stimulated by MeJA.
