ObjectiveTo investigate the therapeutic effect of Astragali Radix-mediated changes in gut microbiota on treating type 2 diabetes （T2DM）. MethodsA 12-week randomized， placebo-controlled clinical trial enrolled eighty patients with newly diagnosed type 2 diabetes and poor glycemic control in the Qi deficiency type. All patients received insulin therapy. The observation group （40 cases） was administered with Astragali Radix Granules， while the control group （40 cases） received a placebo. Both treamtents were taken orally twice daily. Changes in gut microbiota were assessed by 16s rDNA sequencing. Serum glucagon-like peptide-1 （GLP-1） levels were measured using enzyme-linked immunosorbent assay （ELISA）. Glucose metabolism indicators including fasting blood glucose （FPG）， 2-hour postprandial blood glucose （2 h PG），glycated albumin（GA）， and glycated hemoglobin （HbA1c） were evaluated. Pancreatic function was evaluated using fasting C-peptide （FCP）， 2-hour postprandial C-peptide （2 h CP）， and C-peptide area under the curve （AUC_cp）. Traditional Chinese medicine （TCM） syndrome scores， clinical efficacy， and safety indicators were also observed. ResultsIn terms of glucose metabolism indicators， compared with the baseline， both groups exhibited significantly lower FPG， 2 h PG， GA and HbA1C （P<0.01），while FCP， 2 h CP and AUC_cp were significantly higher （P<0.01）. Compared with the control group after the treatment， the observation group showed significantly lower FPG， 2 h PG， GA and HbA1C（P<0.05， P<0.01），and significantly higher FCP， 2 h CP and AUC_cp （P<0.05， P<0.01）， indicating that Astragali Radix can improve glucose metabolism. In terms of the diversity of gut microbiota， no significant differences were detected in the Chao1， Shannon and Simpson indexes of the two groups compared with their respective baselines. However， compared with the post-treatment control group， the observation group demonstrated significant increases in the Chao1， Shannon and Simpson indexes （P<0.05， P<0.01）. The β-diversity analysis showed significant separation in gut microbiota composition before and after treatment in both groups， indicating that Astragali Radix can significantly alter the structure and improve the diversity of gut microbiota. At the phylum level， compared with the baseline， both groups showed a significant increase in the relative abundance of Bacteroidota（P<0.01）. The relative abundance of the potentially harmful phylum Proteobacteria was significantly lower in the observation Group after treatment （P<0.01）. Compared with the post-treatment control group， the observation group had a significantly higher relative abundance of Bacteroidota（P<0.01）. No significant difference was found in Firmicutes/Bacteroidota （F/B） ratio between the two groups after treatment， and other phyla showed no significant differences. At the genus level， compared with the baseline， the observation group exhibited a significant increase in Bacteroides （P<0.01） and a significant decrease in Escherichia-Shigella （P<0.01）， whereas no significant difference was seen in the control group . Compared with the control group after treatment， the observation group after treatment had a significantly higher relative abundance of Bacteroides （P<0.01）. No significant differences were seen in other genera. Linear discriminant analysis （LDA） identified potential characteristics taxa： in the observation group， Bacteroidota at the phylum level and Bacteroides and Dubosiella at the genus level， in the control group， Proteobacteria at the phylum level as well as Barnesiella and Staphylococcus at the genus level. Correlation analysis based on a heatmap revealed that GLP-1 levels were positively correlated with Firmicutes， F/B ratio and Fusobacterium， and negatively correlated with Bacteroidota， Proteobacteria， Bacteroides and Escherichia-Shigella. In terms of clinical efficacy， compared with the control group， the total effective rate of the observation group was significantly higher （P<0.05）. Compared with the baseline， the scores for shortness of breath， fatigue， weakness， spontaneous sweating and reluctance to speak significantly decreased in both groups （P<0.01）. Compared with the control group after treatment， the score for weakness was significantly lower in the observation group （P<0.01），indicating that Astragali Radix could improve clinical symptoms and alleviate weakness symptoms. In terms of safety， compared with the baseline， alanine aminotransferase （ALT） levels significantly decreased in both groups （P<0.05，P<0.01），indicating that Astragali Radix did not induce any significant abnormalities in liver and kidney functions. ConclusionAstragali Radix demonstrates the potential to significantly improve the gut microbiota environment in patients of newly diagnosed type 2 diabetes with Qi deficiency. The therapeutic effect may contribute to glycemic control， possibly mediated by an elevation in GLP-1 level. These findings may support its further clinical investigations and potential applications.

Definitive chemoradiotherapy (dCRT) has become a cornerstone in the treatment of locally advanced esophageal cancer; however, local control remains suboptimal, and persistent lesions or locoregional recurrences after treatment are not uncommon. For patients without distant metastases but with local failure, whether surgical intervention can still offer curative potential remains a major clinical dilemma. Salvage esophagectomy (SE) offers potential long-term survival for selected patients, but this procedure is performed in the context of severe fibrosis, impaired local blood supply, and obscured anatomical planes following chemoradiotherapy, resulting in significantly higher perioperative risk compared to primary esophagectomy. Consequently, controversies exist regarding patient selection, preoperative restaging, choice of surgical approach, extent of lymphadenectomy, gastrointestinal reconstruction, and perioperative management. In recent years, with the refinement of restaging modalities such as PET/CT, the accumulation of experience in high-volume centers, and emerging evidence from clinical studies, the clinical role of SE has gradually shifted from a "high-risk salvage measure" to a "selective curative strategy aimed at achieving long-term survival in carefully selected patients". Nevertheless, standardized guidelines for patient selection, technical approaches, and perioperative management are still lacking. Based on current evidence and clinical experience, experts organized by the Integrated Esophageal Cancer Committee of Chinese Anti-Cancer Association systematically reviewed key issues regarding SE, including its definition, indications, preoperative evaluation, choice of surgical approach, lymphadenectomy, gastrointestinal reconstruction, and perioperative management, and formulated a Chinese expert consensus. This consensus aims to provide guidance for standardized assessment, appropriate referral, individualized surgical decision-making, and optimized perioperative management of patients with locoregional failure after dCRT. Ultimately, this will increase the likelihood of R0 resection, reduce the risk of severe complications, and promote the safer, more judicious, and standardized implementation of SE in high-risk scenarios.

ObjectiveTo investigate the mechanism of danshenol A （DA） pretreatment in alleviating myocardial ischemia-reperfusion injury （MIRI） by regulating cardiomyocyte ferroptosis by in vivo and in vitro experiments. MethodsA MIRI model was established in SD rats， and an in vitro oxygen-glucose deprivation/reoxygenation （OGD/R） model was constructed with H9C2 cells. Both models were treated with DA. H9C2 cells were allocated into blank， model （OGD/R）， DA， ferroptosis inducer （erastin）， and ferroptosis inhibitor （Fer-1） groups. Cell viability was assessed by the methyl thiazolyl tetrazolium （MTT） assay. Biochemical assays were performed to measure the superoxide dismutase （SOD）， malondialdehyde （MDA）， glutathione （GSH）， and ferrous ion （Fe²⁺） levels. Dihydroethidium （DHE） fluorescence assay was adopted to quantify the reactive oxygen species （ROS） level. Real-time PCR and Western blot were employed to quantify the mRNA and protein levels， respectively， of prostaglandin-endoperoxide synthase 2 （PTGS2）， glutathione peroxidase 4 （GPX4）， ferritin heavy chain 1 （FTH1）， and acyl-coA synthetase long-chain family 4 （ACSL4）. Sixty SPF-grade healthy male SD rats were randomly assigned to control， model （MIRI）， DA， erastin， and Fer-1 groups. Enzyme-linked immunosorbent assay （ELISA） was adopted to measure the serum levels of cardiac troponin I （cTnI）， lactate dehydrogenase （LDH）， and creatine kinase （CK）. Histopathological changes in the myocardial tissue were observed by hematoxylin-eosin （HE） staining. Cardiomyocyte apoptosis was detected by terminal deoxynucleotidyl transferase-mediated nick end labeling （TUNEL）. The effect of DA on cardiomyocyte ferroptosis were observed and analyzed by in vivo and in vitro experiments. ResultsIn vitro experiment： compared with the blank group， the OGD/R model group showed reduced cell viability， elevated levels of ROS， MDA， and Fe²⁺， up-regulated mRNA and protein levels of ACSL4， lowered levels of SOD and GSH， and down-regulated mRNA and protein levels of PTGS2， GPX4， and FTH1 （P<0.05，P<0.01）. The DA and Fer-1 groups exhibited consistent trends： cell viability， SOD and GSH levels， and the mRNA and protein levels of PTGS2， GPX4， and FTH1 were significantly restored， while the ROS， MDA， and Fe²⁺ levels， and the mRNA and protein levels of ACSL4 were reduced （P<0.05，P<0.01）. In vivo experiment： Compared with the control group， the MIRI model group showed elevated serum levels of cTnI， LDH， and CK， increased cardiomyocyte apoptosis rate， risen levels of ROS， MDA， and Fe²⁺， and up-regulated mRNA and protein levels of ACSL4. However， both DA and Fer-1 groups exhibited reductions in the indicators above （P<0.05）. Compared with the control group， the MIRI model group demonstrated reduced levels of SOD and GSH and down-regulated mRNA and protein levels of PTGS2， GPX4， and FTH1 （P<0.05）. In contrast， both DA and Fer-1 upregulated these indicators （P<0.05）， effectively reversing the trends in the model group. In addition， the MIRI model group showed swelling of cardiomyocytes， disarrangement of cardiac muscle fibers， and massive inflammatory cell infiltration， which were alleviated in the DA and Fer-1 groups. ConclusionDA alleviates MIRI by inhibiting ferroptosis and inflammation， demonstrating therapeutic potential in acute myocardial infarction.

ObjectiveTo improve the therapeutic effect of Buyang Huanwutang（BYHW） on diabetic kidney disease （DKD） and explore new methods for developing new Chinese medicine decoctions，we utilized 5-hydroxymethylcytosine （5hmC）-Seal sequencing technology and network pharmacology to modify BYHW. MethodsWe selected 14 diabetes mellitus （DM） patients and 15 DKD patients hospitalized in the Department of Endocrinology of Peking University Third Hospital in 2021. Circulating free DNA （cfDNA） in the patients’ plasma was sequenced. After data processing and screening， we performed temporal clustering analysis to select a DKD 5hmC gene set， which was then cross-validated with a DKD database gene set to obtain the DKD gene set. We retrieved target genes of the seven herbal components of BYHW from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform （TCMSP） and the Encyclopedia of Traditional Chinese Medicine （ETCM）， and performed cross-analysis with the DKD gene set to identify common genes shared by the disease and the Chinese medicines. A protein-protein interaction （PPI） network was constructed for the common genes to screen out the key genes. Chinese medicines targeting these key genes were searched against ETCM to identify removable Chinese medicines. Kyoto Encyclopedia of Genes and Genomes （KEGG） enrichment analysis was performed on non-common DKD genes， and key genes in DKD-related pathways were selected based on machine learning. The GSE30529 dataset was used to verify the expression trends of 5hmC-modified genes and the feasibility of target genes as drug targets. TCMBank was used to search for target genes and obtain compounds targeting these genes and the corresponding Chinese medicines to construct a "key target-compound-Chinese medicine" network. Molecular docking was employed to verify the binding affinity of compounds with key targets. TCMSP and ETCM were used to search and count the candidate Chinese medicines targeting DKD-related genes， and a new decoction was formed by adding the selected Chinese medicines. A mouse model of DKD was established to examine the efficacy of the new decoction based on the mouse body mass， random blood glucose， urinary microalbumin （mALB）， serum creatinine （Scr）， and blood urea nitrogen （BUN） and by hematoxylin-eosin staining， periodic acid-Schiff staining， Masson staining， immunofluorescence assay， and Real-time PCR. ResultsThe cross-analysis results showed that the DKD gene set included 507 genes， of which 30 were target genes of BYHW. The PPI analysis indicated that the top 15% target genes regarding the degree were interleukin-6 （IL-6）， Toll-like receptor 4 （TLR4）， lactotransferrin （LTF）， lipoprotein lipase （LPL）， and sterol regulatory element-binding transcription factor 1 （SREBF1）. Persicae Semen and Pheretima in BYHW were unrelated to key genes and removed. Machine learning identified 10 potential target genes， among which TBC1 domain family member 5 （TBC1D5）， RAD51 paralog B （RAD51B）， and proteasome 20S subunit alpha 6 （PSMA6） had expression trends consistent with the GSE30529 dataset and could serve as drug targets. The "key target-compound-Chinese medicine" network and molecular docking results indicated that the compounds with good binding affinity to target proteins were arginine， glycine， myristicin， serine， and tyrosine， corresponding to 121 Chinese medicines. The top 10 Chinese medicines targeting DKD-related genes were Lycii Fructus， Ginseng Radix et Rhizoma， Dioscoreae Rhizoma， Rehmanniae Radix Praeparata， Isatidis Radix， Glehniae Radix， Ophiopogonis Radix， Allii Sativi Bulbus， Isatidis Folium， and Bolbostemmatis Rhizoma. Based on traditional Chinese medicine theory， the new decoction was obtained after removal of Persicae Semen and Pheretima and addition of Rehmanniae Radix Praeparata and Dioscoreae Rhizoma. Animal experiment results indicated that the modified BYHW improved the kidney function and inhibited renal fibrosis in DKD mice， with better effects than the original decoction. ConclusionThe BYHW modified based on 5hmC-Seal sequencing demonstrates better performance in inhibiting fibrosis and ameliorating DKD than the original decoction. This elucidates the biomedical theory behind the epigenetic modification of traditional Chinese medicine prescriptions， potentially offering new perspectives for the exploration of these prescriptions

Limited-stage small cell lung cancer(SCLC)is a highly malignant and rapidly progressing neuroendocrine tumor,while uremia is a complication of the end-stage of chronic renal failure.The patients with SCLC complicated with uremia have poor treatment tolerance,limited options for anti-tumor treatment regimens,and great difficulty in diagnosis and treatment.This study analyzed one case of a 69-year-old male patient with limited-stage SCLC complicated with uremia(with a history of regular hemodialysis,3 times per week),to discuss his first-line treatment regimen,efficacy,and the impact of hemodialysis on the plasma concentrations of the anti-tumor drugs,and reviewed the relevant literature to provide a reference for the treatment of similar patients.The patient was admitted to the hospital due to"cough and hemoptysis for half a month"and was diagnosed with limited-stage SCLC stage ⅢA(T2aN2M0)by computed tomography(CT)and lung puncture biopsy.After discussion by the multi-disciplinary treatment(MDT)team,the patient received 6 cycles of Etoposide(VP-16)+carboplatin chemotherapy combined with adebrelimab immunotherapy,followed by sequential adebrelimab maintenance therapy.The efficacy was evaluated as partial response(PR)and the response is ongoing.During the treatment,level 4 hemoglobin decrease,level 3 neutropenia,and level 2 leukopenia occurred,which were alleviated after symptomatic treatment.The blood concentration monitoring results showed that the plasma concentrations of etoposide and carboplatin increased rapidly during drug infusion,and gradually decreased after the end of infusion.Hemodialysis could rapidly reduce the plasma concentration of carboplatin,but had no significant effect on the plasma concentration of etoposide.Therefore,the immunotherapy combined with reduced-dose chemotherapy regimen is safe and effective for this type of patient.Plasma drug concentration monitoring can be used to observe drug metabolism,but the optimal monitoring time points and clinical value need further study and validation.

Objective To explore the relationship between triglyceride-glucose index(TyG)and acute ischemic stroke with large vessel occlusion(AIS-LVO)of anterior circulation.Methods A retrospective study was conducted on patients with anterior circulation AIS-LVO who underwent emergency endovascular thrombectomy at Neurovascular Center of The First Affiliated Hospital of Naval Medical University from Jan.2018 to Dec.2019.According to modified Rankin scale(mRS)score 90 d after operation,the patients were assigned to favorable outcome group(mRS score 0-2)or unfavorable outcome group(mRS score 3-6),and the TyG was compared.According to the median of TyG,the patients were assigned to low-TyG group(TyG＜8.57)or high-TyG group(TyG ≥8.57),and the clinical data,laboratory indexes,and imaging characteristics were compared.Receiver operating characteristic curve was used to evaluate the predictive value of TyG for poor prognosis.Results A total of 135 patients were enrolled,with 72 in the favorable outcome group and 63 in the unfavorable outcome group.The TyG of the unfavorable outcome group was significantly higher than that of the favorable outcome group(8.82+0.63 vs 8.43+0.60,P＜0.001).There were 67 patients in the low-TyG group and 68 in the high-TyG group.Compared with the low-TyG group,the proportion of patients with hyperlipidemia history(P=0.003),systolic blood pressure at admission(P=0.018),fasting blood glucose level(P＜0.001),and triglyceride level(P＜0.001)were significantly higher in the high-TyG group,the infarct core volume was significantly larger(P=0.025),the high density lipoprotein-cholesterol level was significantly lower(P=0.013),and the mRS score 90 d after operation was significantly higher(3[1,5]vs 1[0,5],P=0.049).The TyG had certain predictive value for poor prognosis in anterior circulation AIS-LVO patients(area under curve value=0.662,95％confidence interval 0.571-0.753).Conclusion TyG is elevated in anterior circulation AIS-LVO patients with poor prognosis,and may be a potential prognostic indicator for anterior circulation AIS-LVO patients.

Objective To analyze the characteristics of influenza incidence and the changes of innate immune cells among children who visited the pediatric outpatient or emergency department of a hospital in Shanghai from Jan.2019 to Dec.2023,so as to provide references for the prevention of influenza in children.Methods Influenza-like illness(ILI)children who first visited the pediatric outpatient or emergency department of The First Affiliated Hospital of Naval Medical University from Jan.2019 to Dec.2023,and underwent influenza virus antigen or nucleic acid testing were enrolled.Their clinical and laboratory data were collected for retrospective analysis.With a month as the basic monitoring unit,a line chart was used to describe the changes in the number of influenza cases and the positive rate.Then,these cases were assigned to pre-coronavirus disease 2019(COVID-19)group(Jan.2019 to Dec.2019),mid-COVID-19 group(Jan.2020 to Dec.2022),or post-COVID-19 group(Jan.2023 to Dec.2023),and the influenza positive rates among these groups were compared.To further observe the changes of the innate immune cells of children with influenza A after non-pharmacological intervention(NPI)measures,considering the development characteristics of children's white blood cells,children with influenza A were assigned to 2 subgroups according to age:0-6 years or 7-16 years.Within each subgroup,they were assigned to pre-NPI group or post-NPI group according to time.A ratio of 1∶1 matching was carried out according to gender and age using propensity score matching,and the blood routine parameters were compared between the 2 groups.Results A total of 41 028 ILI children were enrolled.During the COVID-19 period from Jan.2020 to Dec.2022,the influenza positive rates decreased significantly(P＜0.001),and almost no influenza virus was detected.The peak of influenza reappeared in Mar.2023,with a lag in the peak period,but higher than previous years'peak,and the speed of reaching the peak was faster.In each subgroup,the white blood cell count and lymphocyte ratio of children with influenza A in the post-NPI group were lower than those in the pre-NPI group(all P＜0.001),and the monocyte ratio was higher than that in the pre-NPI group(both P＜0.001).Conclusion The implementation of NPI measures during COVID-19 leads to disruption of influenza transmission route and changes in the epidemic trend of influenza.The influenza virus causes serious public health problems after COVID-19 period,and children with influenza A experience more serious immune response.It is recommended to strengthen the vaccination of influenza vaccine before the flu season.

Objective To explore the mediating role of mindful attention and awareness in depressive symptoms and insomnia severity among patients with comorbid depression and insomnia.Methods A cross-sectional study was conducted,enrolling 267 patients with comorbid depression and insomnia who were treated in the outpatient Department of Medical Psychology of Second Affiliated Hospital of Army Medical University,from March to May 2024.Basic demographic and clinical data were collected using a general information questionnaire.Depressive symptom severity was measured via the Patient Health Questionnaire-9(PHQ-9),insomnia severity via the Insomnia Severity Index(ISI),perceived stress via the Perceived Stress Scale-10(PSS-10),and mindful attention and awareness via the Mindful Attention Awareness Scale(MAAS).Pearson correlation analysis was used to examine the correlations between depressive severity,insomnia severity,perceived stress,and mindful attention and awareness.Mediation analysis was performed using Process 4.1.Results The PHQ-9 score was(13.80±5.98)and the ISI score was(17.10±5.56)in the 267 patients.Pearson correlation analysis showed that depressive severity and insomnia severity were positively correlated with perceived stress(r=0.531,0.351,P<0.001)and negatively correlated with mindful attention and awareness(r=-0.373,-0.350,P<0.001).Mediation analysis using Process 4.1 indicated that the combined mediating effect of mindful attention and awareness and insomnia between perceived stress level and depressive level was 0.157,with a 95%confidence interval(CI)of 0.102～0.217,and the total mediating effect was significant(P<0.001).Conclusion Perceived stress directly positively affects depression and indirectly exacerbates depression through insomnia as a mediator,and mindful attention and awareness can weaken the promoting effect of perceived stress on insomnia.
