ObjectiveThis study aims to investigate the molecular mechanism by which Guizhi Fulingwan （GFW） inhibits ferroptosis in endometriosis （EMT） through the regulation of the hypoxia inducible factor-1α/heme oxygenase 1 （HIF-1α/HO-1） signaling pathway. MethodsMachine learning was employed to identify ferroptosis-related biomarkers associated with EMT. Network pharmacology was utilized to identify the active components of GFW and its potential therapeutic targets against EMT， including core targets. Functional enrichment analysis was conducted to explore the biological processes， molecular functions， cellular components， and signaling pathways associated with the potential targets. An EMT rat model was established via autologous transplantation. Thirty female Sprague-Dawley （SD） rats were randomly divided into five groups： sham-operated， model， positive control （dienogest at 0.2 mg·kg^-1）， low-dose GFW （2.5 g·kg^-1）， and high-dose GFW （5 g·kg^-1）. After modeling， the rats received their respective treatment by oral gavage for 28 consecutive days， while the sham and model groups received equal volumes of distilled water. Serum and ectopic endometrial tissues were collected. Hematoxylin and eosin （HE） staining was employed to evaluate morphological alterations in ectopic lesions. Quantitative real-time polymerase chain reaction （Real-time PCR） and Western blot were conducted to assess mRNA and protein expression of HIF-1α， HO-1， glutathione peroxidase 4 （GPX4）， spermidine/spermine N1-acetyltransferase （SAT1）， and prostaglandin-endoperoxide synthase 2 （PTGS2）. Tissue levels of malondialdehyde （MDA）， glutathione （GSH）， and ferrous iron （Fe²⁺） were quantified using commercial assay kits. Serum levels of interleukin-6 （IL-6） and transforming growth factor-β₁ （TGF-β₁） were measured via enzyme-linked immunosorbent assay （ELISA）. ResultsFive ferroptosis-related biomarkers in EMT were identified： ALOX12， CHAC1， SAT1， AST1， and HO-1. Network pharmacology analysis revealed 42 active components of GFW and 192 potential therapeutic target genes related to EMT treatment， with FOS， JUN， HO-1 identified as core targets. Functional enrichment analysis indicated that the potential targets were primarily involved in oxidative stress response and reactive oxygen species metabolism and were enriched in the HIF-1 signaling pathway. Compared to the sham-operated group， the model group exhibited significant increases in both mRNA and protein expression of HIF-1α， HO-1， and PTGS2， as well as elevated tissue levels of Fe²⁺ and MDA. Conversely， GSH levels and the expression of GPX4 and SAT1 were markedly reduced， and serum levels of IL-6 and TGF-β₁ levels were significantly higher （P<0.01）. Compared with the model group， all GFW-treated groups showed significant downregulation of HIF-1α and HO-1， reduced Fe²⁺ levels， and downregulated expression of MDA， PTGS2， IL-6， and TGF-β₁. Meanwhile， GSH， GPX4， and SAT1 expression levels were significantly increased （P<0.05， P<0.01）， effectively ameliorating iron overload and oxidative stress， thereby demonstrating therapeutic efficacy in EMT， with the high-dose GFW demonstrating the most pronounced therapeutic effects. ConclusionGFW exerts therapeutic effects on endometriosis by regulating the HIF-1α/HO-1 signaling pathway to rectify iron metabolism disorders and attenuate free iron-induced oxidative damage. It upregulates the antioxidative defense system to inhibit lipid peroxidation cascades and modulates inflammatory cytokine networks. These effects collectively disrupt the pathological interaction between ferroptosis and chronic inflammation， providing a novel theoretical foundation for the clinical application of GFW in EMT treatment.

Premature constriction or closure of fetal ductus arteriosus usually occurs during late pregnancy, causing cardiac ventricular size disproportion (right and left heart asymmetry), which are usually clues for the diagnosis. We reported a case of a fetus with an enlarged right heart, reduced wall motion of the right ventricle, and severe tricuspid regurgitation identified by echocardiography at 37 +2 gestational weeks. Furthermore, the fetal ductus arteriosus was unclear on two-dimensional fetal echocardiography, and high-velocity flow was detected at the site by pulsed-wave Doppler, suggesting a significant premature constriction of fetal ductus arteriosus. The elective cesarean section was performed after the examination day. Three months postpartum examination showed no obvious abnormalities in the heart of the newborn.

Tung tree (Vernicia fordii) is an economically important woody oil plant that produces tung oil rich in eleostearic acid. Here, we report a high-quality chromosome-scale genome sequence of tung tree. The genome sequence was assembled by combining Illumina short reads, Pacific Bio-sciences single-molecule real-time long reads, and Hi-C sequencing data. The size of tung tree gen-ome is 1.12 Gb, with 28,422 predicted genes and over 73％ repeat sequences. The V. fordii underwent an ancient genome triplication event shared by core eudicots but no further whole-genome duplication in the subsequent ca. 34.55 million years of evolutionary history of the tung tree lineage. Insertion time analysis revealed that repeat-driven genome expansion might have arisen as a result of long-standing long terminal repeat retrotransposon bursts and lack of efficient DNA deletion mechanisms. The genome harbors 88 resistance genes encoding nucleotide-binding sites;17 of these genes may be involved in early-infection stage of Fusarium wilt resistance. Further, 651 oil-related genes were identified, 88 of which are predicted to be directly involved in tung oil biosynthesis. Relatively few phosphoenolpyruvate carboxykinase genes, and synergistic effectsbetween transcription factors and oil biosynthesis-related genes might contribute to the high oil content of tung seed. The tung tree genome constitutes a valuable resource for understanding genome evolution, as well as for molecular breeding and genetic improvements for oil production.

Objective To discuss the contribution of clinical pharmacists in anti-infection treatment of a patient with multiple organ dysfunction syndrome ( MODS) undergoing continuous renal replacement therapy ( CRRT). Methods Pharmacists participated in the anti-infection treatment of a MODS patient undergoing CRRT.Pharmacists assisted physicians in optimizing the therapeutic regimen based on treatment guidelines and relative information. Results Physicians accepted the advice of pharmacists after comprehensive evaluation.Ten days later,the patient recovered from shock,as the infection indexes were improved significantly.He then moved back to the general ward. Conclusion Pharmacists should positively participate in clinical treatment with physicians,in order to play a critical role in ensuring the safety and efficacy of the medication.

OBJECTIVETo explore common biological pathways for attention deficit hyperactivity disorder (ADHD) and low birth weight (LBW).

METHODSThei-Gsea4GwasV2 software was used to analyze the result of genome-wide association analysis (GWAS) for LBW (pathways were derived from Reactome), and nominally significant (P< 0.05, FDR< 0.25) pathways were tested for replication in ADHD.Significant pathways were analyzed with DAPPLE and Reatome FI software to identify genes involved in such pathways, with each cluster enriched with the gene ontology (GO). The Centiscape2.0 software was used to calculate the degree of genetic networks and the betweenness value to explore the core node (gene). Weighed gene co-expression network analysis (WGCNA) was then used to explore the co-expression of genes in these pathways.With gene expression data derived from BrainSpan, GO enrichment was carried out for each gene module.

RESULTSEleven significant biological pathways was identified in association with LBW, among which two (Selenoamino acid metabolism and Diseases associated with glycosaminoglycan metabolism) were replicated during subsequent ADHD analysis. Network analysis of 130 genes in these pathways revealed that some of the sub-networksare related with morphology of cerebellum, development of hippocampus, and plasticity of synaptic structure. Upon co-expression network analysis, 120 genes passed the quality control and were found to express in 3 gene modules. These modules are mainly related to the regulation of synaptic structure and activity regulation.

CONCLUSIONADHD and LBW share some biological regulation processes. Anomalies of such proces sesmay predispose to ADHD.

Methods:In this study,90 different grades of hypertension patients with acute pulpitis were recruited from February 201 4 to February 201 5 in the Department of Oral Emergency,Peking University School and Hospital of Stomatology.The information about the patients’general health,oral treatment,life signs of change information was collected.Patients were divided into high risk group,middle risk group, and low risk group (30 patients for each group).Results:(1 )Compared with the preoperative,systolic blood pressure (90%),diastolic blood pressure (80%),heart rate increase (1 00%)were increased in the high risk group.The increase rates of the middle risk group and the low risk group were significantly lower than those of the high risk group (P<0.01 ).At the same time,the systolic blood pressure of 1 /4 (26.7%)patients in high risk group increased more than 20 mmHg (1 mmHg=0.1 33 kPa),and the diastolic blood pressure of 2/5 patients in high risk group increased more than 1 0 mmHg,the difference was statistically significant compared with the other two groups (P<0.05).(2)Compared with the pre-operative,the average increase of the maximum peak were increased [systolic blood pressure (1 8.0 ± 1 .5)mmHg,diastolic blood pressure (8.0 ±1 .7)mmHg],the mean of heart rate changes [(7.0 ± 0.3)beats per minute]was also increased in the high risk group,while these two indicators were de-creased in the low risk group and the middle risk group.The electrocardiogram (ECG)was changed in 6 cases during the treatment in the high risk group.No significantly changed were observed in the low risk group and the middle risk group.(3 ) Compared the risk assessment in preoperative with that in postoperative,in the middle risk group,23 cases were evaluated as medium risk in final evaluation,6 as low risk,and 1 as high risk (risk assessment increased);in the high risk group,20 cases were evaluated as high risk,7 as very high risk,and 3 as medium risk (risk assessment decreased).Conclusion:Oral treatment is very safe for patients with hypertension,but the risk factor,target organ damage,and com-plications will also increase the risk of cardiovascular events in elderly patients during the acute pulpitis treatment.Dentist should take some measures to avoid the risks.

OBJECTIVETo investigate the effects of intragastric administration of human interferon-α (hIFN-α)-transformed Bifidobacterium on immune functions of mice.

METHODSThe E.coli-Bifidobacterium shuttle expression vector containing hIFN-α gene was constructed and transformed into Bifidobacterium. The hIFN-α-transformed Bifidobacterium suspension (1010 /ml) was prepared after induction with 0.2% L-arabinose for hIFN-α expression and administered intragastrically in male Balb/C mice at the dose of 0.1 ml every other day for 2 weeks, with the mice receiving empty vector-transformed Bifidobacteria as the negative control and those having an equal volume of saline as the blank control. The percentages of mononuclear cell subsets in the thymus, spleen and blood were detected in the mice by flow cytometry, and the serum levels of IL-4, IL-12, IFN-γ and TNF-α were assayed using mouse cytokine FlowCytomix Kit.

RESULTSThe percentages of CD3⁺CD8⁺ and CD4⁺CD8⁺ cells in the thymus, CD3⁺CD4⁺, CD3⁺CD8⁺ and CD4⁺CD8⁺ cells in the spleen, and CD3⁺CD8⁺ cells in the blood all increased significantly in IFN group as compared with those in the negative and blank control groups (P<0.01 or 0.05). The serum level of IFN-γ also increased significantly (P<0.05) while IL-4 level remained unchanged in IFN group compared with those in the two groups.

CONCLUSIONIntragastric administration of hIFN-α-transformed Bifidobacterium promotes lymphocyte proliferation and maturation and increases the serum levels of Th1 cytokines in mice.
