Esophageal cancer （EC） is a highly prevalent malignant tumor in China. The phosphatidylinositol 3-kinase （PI3K）/protein kinase B （Akt） signaling pathway， as one of the key oncogenic pathways， can promote the cell cycle progression， proliferation， migration， and invasion， induce chemoresistance， and inhibit apoptosis and autophagy of EC cells. Traditional Chinese medicine （TCM）， with the advantages of targeting multiple points with multiple components to delay cancer progression， can target the PI3K/Akt signaling pathway for EC treatment. This article preliminarily discusses the molecular mechanism and role of the PI3K/Akt signaling pathway in EC and elaborates on the specific targets and efficacy of TCM in treating EC through intervention in the PI3K/Akt signaling pathway in the past five years. TCM materials and extracts inhibiting the PI3K/Akt signaling pathway in EC include Borneolum， spore powder of Ganoderma lucidum without spore coat， extract of Celastrus orbiculatus， root extract of Taraxacum， and Bruceae Fructus oil emulsion. TCM active ingredients exerting the effect include flavonoids， terpenoids， saponins， phenols， polysaccharides， alkaloids， and other compounds. TCM compound prescriptions with such effect include Qige San， Huqi San， Xuanfu Daizhetang， Tongyoutang and its decomposed prescriptions， Liujunzi Tang， and Xishenzhi Formula. In addition， TCM injections such as Compound Kushen Injection and Kang'ai injection also inhibit the PI3K/Akt signaling pathway in EC. This paper summarizes the role of the PI3K/Akt signaling pathway in EC and the TCM interventions， aiming to provide reference for the research and clinical application of new drugs for EC.

OBJECTIVE To evaluate the efficacy and safety of immune checkpoint inhibitors （ICIs） combined with neoadjuvant chemotherapy in the treatment of early triple-negative breast cancer （TNBC）. METHODS Randomized controlled trials （RCTs） comparing ICIs combined with neoadjuvant chemotherapy （experimental group） versus neoadjuvant chemotherapy alone （control group） were retrieved from PubMed， Cochrane Library， Embase， Web of Science， CNKI， Wanfang Data， and VIP databases， as well as relevant studies published at oncology academic conferences. The search period was from database inception to June 30， 2025. After literature screening， data extraction， and quality assessment， a meta-analysis was performed by using RevMan 5.4 software. RESULTS A total of 6 RCTs involving 3 786 patients were finally included. The meta-analysis results showed that the experimental group had superior event-free survival [HR＝0.73， 95%CI （0.62， 0.85）， P＜0.000 1]， overall survival [HR＝0.69， 95%CI （0.57， 0.84）， P＝0.000 3]， and pathological complete response （pCR） [OR＝1.57， 95%CI （1.37， 1.80）， P＜0.000 01] compared to the control group. The incidence of ≥grade 3 adverse event （AE）， severe AE （SAE）， and ≥ grade 3 immune-related adverse event （irAE） in the experimental group was significantly higher than that in the control group. There was no statistically significant difference between the two groups in the incidence of any AE or any irAE （P＞0.05）. Subgroup analysis revealed that， regardless of programmed cell death ligand 1 expression status （negative or positive），the pCR in the experimental group was significantly higher than that in the control group （P＜0.05）. Additionally， the pCR of the patients with positive lymph nodes in the experimental group was significantly higher to that in the ontrol group （P＜0.05）. There was no statistically significant difference in pCR between the two groups with negative lymph nodes （P＝0.09）. CONCLUSIONS ICIs combined with neoadjuvant chemotherapy can significantly improve event-free survival and overall survival in patients with TNBC， providing patients with long-term survival benefits. However， the risk of ≥ grade 3 AE， SAE and ≥ grade 3 irAE has increased.

ObjectiveTo systematically summarize the relevant pathophysiology underlying muscle fatigue in myalgic encephalomyelitis/chronic fatigue syndrome (ME/CFS). MethodsDatabases including PubMed, Web of Science Core Collection, Embase, Cochrane Library, EBSCO (CINAHL), CNKI, Wanfang Data and VIP Database were searched from their inception to July, 2025 for basic and clinical studies related to ME/CFS. Multidimensional evidence involving mitochondrial, neuromuscular junction dysfunction, autonomic dysregulation and immune-inflammatory responses was integrated. The role of muscles in the central-immune-metabolic-neural regulatory network and its association with clinical phenotypes were evaluated. ResultsPatients with ME/CFS commonly presented with impaired mitochondrial energy supply, oxidative stress, ion homeostasis disorders, reduced stability of neuromuscular junction transmission, insufficient central drive and postural intolerance. These abnormalities resulted in a predisposition to cross the anaerobic threshold and trigger post-exertional malaise. ConclusionMuscle pathophysiology plays a critical role in the pathogenesis and symptom persistence of ME/CFS. Rehabilitation practice should prioritize safety boundaries to avoid post-exertional malaise.

OBJECTIVE To construct a predictive tool for surgical site infections(SSIs)in spinal surgery for Chi-nese population to provide evidence support for reducing SSIs.METHODS A systematic review of Chinese and English database literature was conducted for Meta-analysis to obtain pooled risk values for influencing factors,and a risk prediction scoring tool was constructed based on the logistic regression model.Patients who underwent spinal surgery and completed postoperative follow-up in a tertiary hospital in Beijing from Jan.to Dec.2021 were selected to validate the predictive effect of the tool.RESULTS The predictive model for SSIs in Chinese spinal sur-gery patients was Logit(P)=—3.47+0.63(age 60 years)+0.31 ×(patient with cardiovascular disease)+0.69 ×(rheumatoid arthritis)+1.07 ×(diabetes)+1.06 ×(operation duration＞3 h)+1.17 ×(preopera-tive albumin＜35 g/L)+0.71 ×(history of spinal surgery)+0.67 ×(carrying internal implants)+0.73 ×(blood transfusion).The total score of the predictive tool was 92,with a cutoff score of≥24.50 indicating high-risk individuals.The area under the curve was 0.733,with the sensitivity 58.30％and the specificity 79.60％.CONCLUSION The established predictive model for SSIs in Chinese spine surgery demonstrates good predictive performance and can be used as a reference assessment tool in clinical practice.

Alveolar soft part sarcoma(ASPS)is a rare malignant tumor characterized by a lack of specific clinical manifestations,often presenting as painless,progressively enlarging masses.Its occur-rence in the retroperitoneum is uncommon.Due to the large retroperitoneal space,the tumor typically does not cause significant symptoms in the early stages,leading to advanced disease or metastasis at presentation,and consequently,poor prognosis.This article reported the clinical diagnosis and treatment of a patient with retroperitoneal ASPS and elucidated the features of epidemiology,clinical manifesta-tions,diagnostic modalities,and treatment approaches of this disease in conjunction with the literature.

Objective:To investigate the mechanism of ursolic acid regulating HMGB1/TLR4 pathway in reducing intestinal barrier injury in a rat model of ulcerative colitis(UC).Methods:Rats were randomly divided into control group,model group,glycyr-rhizic acid(HMGB1 inhibitor)group,ursolic acid group and glycyrrhizic acid+ursolic acid group,with 12 rats in each group.UC rat model was induced by tritrobenzene sulfonate enema.After drug administration,body weight and disease activity index(DAI)score were performed of rats in each group;pathological morphology of colonic mucosa was detected by HE staining,the thickness of mucosa and height of villi were compared;levels of catalase(CAT),superoxide dismutase(SOD),malondialdehyde(MDA)in colon tissue,levels of serum diamine oxidase(DAO),and intestinal fatty acid binding protein(I-FABP),TNF-α,IL-18,IL-6 were detected by kits;expression levels of tight junction proteins(Claudin-1,ZO-1,Occludin)and HMGB1/TLR4 pathway proteins(HMGB1,TLR4,MyD88)in colon tissues were detected by Western blotting.Expression levels of HMGB1,TLR4 and MyD88 in colonic tissue were detected by immunohistochemistry.Results:Compared with control group,colonic mucosal tissue of model group had severe pathological injury,the body weight,mucosal thickness,villus height,CAT,SOD,Claudin-1,ZO-1 and Occludin levels in colon tis-sue were significantly reduced,while DAI score,serum DAO,I-FABP,TNF-α,IL-18 and IL-6 levels,colon tissue MDA,HMGB1,TLR4 and MyD88 levels were significantly increased(P<0.05);compared with model group,pathological injury of colonic mucosal tissue of rats in ursolic acid group,glycyrrhizic acid group and glycyrrhizic acid+ursolic acid group were reduced,body weight,muco-sal thickness,villus height,colon tissue CAT,SOD,Claudin-1,ZO-1 and Occludin levels were significantly increased,while DAI score,serum DAO,I-FABP,TNF-α,IL-18 and IL-6 levels,colon tissue MDA,HMGB1,TLR4 and MyD88 levels were significantly reduced(P<0.05);combined intervention of glycyrrhizic acid and ursolic acid could enhance the influence of ursolic acid on the above indexes(P<0.05).Conclusion:Ursolic acid can inhibit inflammation,reduce the level of oxidative stress,reduce the colonic mucosal injury of UC rats,repair the intestinal mucosal barrier function,and improve the clinical symptoms of rats,which may be achieved by down-regulating the HMGB1/TLR4 pathway.

Objective To evaluate the efficacy,safety and cost-effectiveness of dorzagliatin in the treatment of type 2 diabetes mellitus using a rapid health technology assessment,and to provide medical evidence for clinical decision-making.Methods PubMed,Embase,Cochrane Library,CNKI,Wanfang Data,SinoMed and relevant health technology assessment(HTA)websites and databases were searched to collect systematic reviews/Meta-analysis,pharmacoeconomic literature and HTA reports of dorzagliatin in the treatment of type 2 diabetes from inception to July 20,2024.Two reviewers independently screened literature,extracted date and assessed quality.The results were qualitatively described and analyzed.Results A total of 6 studies were included,including 5 systematic reviews/Meta-analysis and a pharmacoeconomic study.In terms of efficacy compared with placebo,dorzagliatin significantly reduced glycated hemoglobin(HbA1c),fasting plasma glucose,2-hour postprandial blood glucose and insulin resistance index(P＜0.05),improved HbA1c compliance rate in terms of safety,dorzagliatin,and enhanced homeostasis model assessment-β(P＜0.05),significantly increased total cholesterol,triglyceride,body weight and body mass index(P＜0.05).In terms of safety,the total incidence of adverse reactions of dorzagliatin was slightly higher than that of the placebo group(P＜0.05).However,there was no significant difference in the incidence of severe adverse reactions between the two groups(P＞0.05),and there was no significant increase in the incidence of hyperlipidemia and hypoglycemia(P＞0.05).In terms of economy,the treatment of dorzagliatin combined with metformin has a long-term cost-utility advantage,with an economic probability of nearly 70％.Conclusion Compared with placebo,dorzagliatin has a good overall efficacy and safety in the treatment of type 2 diabetes.In terms of safety,the total incidence of adverse reactions of dorzagliatin was slightly higher than that of placebo.In terms of economy,compared with metformin alone,dorzagliatin combined with metformin has economic advantages.However,there is a lack of head-to-head comparisons of doxorubicin with other classes of glucose-lowering medications,and none of the included studies described long-term cardiac,cerebral,or renal benefits,which limits the comprehensive evaluation of the efficacy and safety of dorzagliatin.

Objective:To evaluate the changes in brain network function indicators in premature infants with language developmental disorders by resting state functional magnetic resonance imaging (rs-fMRI).Methods:Premature infants admitted to Changzhou Children's Hospital Affiliated to Nantong University from January 2021 to December 2023 were selected as the study subjects to evaluate language development. Language development assessment was conducted using the Gesell developmental scales during follow-up until 12 months of corrected gestational age. According to the evaluation results, the subjects were divided into language development disorders group (31 cases) and normal language development group (19 cases). rs-fMRI was performed on all premature infants with corrected gestational age of 40-42 weeks. The amplitude of low frequency fluctuation (ALFF) and regional homogeneity (ReHo) analysis were performed on MRI data. Regions of interest (ROI) were obtained as seed points based on previous literature, then functional connectivity (FC) was extracted between these ROIs for inter-group comparison. Independent sample t-test, non parametric test, chi-square test, and Fisher's exact test were performed on the data using SPSS 23.0 software. Results:(1)There were statistically significant differences in birth weight, gestational age, moderate to severe respiratory distress syndrome, sepsis, and maternal education level between the two groups of premature infants (all P<0.05).(2)The FC values of left temporal gyrus-left angular gyrus (1.220±0.155, 1.139±0.118), left insula-left trigone (0.520±0.199, 0.411±0.152), and left angular gyrus-left marginal gyrus (1.588±0.333, 1.330±0.437) in language development disorders group were higher than those in normal language development group ( t=-2.089, -2.186, -2.359, all P<0.05). There was no statistically significant difference in the FC values of ROI-ROI between the two groups in the right hemisphere of the brain (all P>0.05). The FC values of left superior temporal gyrus-right insula (0.588±0.257, 0.398±0.305) and left superior temporal gyrus-right marginal gyrus (1.550±0.393, 1.374±0.213) in language development disorders group were higher than those in the normal language development group ( t=-2.363, 2.057, both P<0.05). Conclusions:Functional connectivity between local brain regions in preterm infants with language development is significantly enhanced. The change of local brain network functional connectivity has certain predictive value for the language developmental outcome of preterm infants.

Objective:To investigate the protective effect of fluoxetine on neurons in rats with subarachnoid hemorrhage (SAH) and explore its mechanism based on the chemokine receptor 4 (CXCR4)/nucleotide-binding oligomerization domain-like receptor protein 1 (NLRP1) pathway.Methods:Seventy-five rats were randomly divided into a normal control group and a model group. The SAH model was established by the internal carotid artery puncture method in the model group. After modeling, rats were randomly divided into the model group, fluoxetine low-, medium-, and high-dose groups, and nimodipine group, with 12 rats in each group. The fluoxetine low-, medium-, and high-dose groups were intravenously injected with fluoxetine at doses of 5, 10, and 15 mg/kg, respectively; the nimodipine group was intraperitoneally injected with nimodipine at 0.2 mg/kg; the normal control group and model group were intraperitoneally injected with an equal volume of normal saline, once a day for 7 consecutive days. The shuttle box was used to determine the number of avoidance responses and avoidance response time of rats. The water content of brain tissue and Evans blue exudation volume were calculated. Enzyme-linked immunosorbent assay (ELISA) kits were used to detect the levels of interleukin (IL)-6, tumor necrosis factor (TNF)-α, malondialdehyde (MDA), superoxide dismutase (SOD), catalase (CAT), and reduced glutathione (GSH) in the hippocampal tissue. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of hippocampal tissue. Real-time quantitative polymerase chain reaction (RT-qPCR) was used to detect the mRNA levels of CXCR4 and NLRP1 in the hippocampal tissue. Western blot was used to determine the protein levels of CXCR4, NLRP1, LC3-Ⅱ, and Beclin1 in the hippocampal tissue.Results:Compared with the normal control group, the model group had a lower number of avoidance responses, lower levels of SOD, CAT, GSH, CXCR4 mRNA, CXCR4, LC3-Ⅱ, and Beclin1 protein in the hippocampal tissue (all P<0.05); while the avoidance response time, brain water content, Evans blue exudation volume, levels of IL-6, TNF-α, MDA, and mRNA and protein levels of NLRP1 in the hippocampal tissue were higher (all P<0.05). Compared with the model group, the fluoxetine groups (all doses) and nimodipine group had a higher number of avoidance responses, higher levels of SOD, CAT, GSH, CXCR4 mRNA, CXCR4, LC3-Ⅱ, and Beclin1 protein in the hippocampal tissue (all P<0.05); while the avoidance response time, brain water content, Evans blue exudation volume, levels of IL-6, TNF-α, MDA, and mRNA and protein levels of NLRP1 in the hippocampal tissue were lower (all P<0.05); moreover, the changes in various indicators were more significant with the increase of fluoxetine dose. HE staining results showed that there were no pathological changes in the hippocampal tissue of the normal control group; in the model group, the number of hippocampal neurons decreased, nuclei were pycnotic, and cell arrangement was irregular. Compared with the model group, the number of hippocampal neurons increased, cell arrangement was regular, and hippocampal pathology was significantly restored in the fluoxetine groups (all doses) and nimodipine group. Conclusions:Fluoxetine can significantly alleviate the pathological progression of cerebral edema, repair neuronal damage, improve neurological function, and regulate mitochondrial autophagy in SAH rats, whose mechanism may be related to the regulation of the CXCR4/NLRP1 pathway.
