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.

The principle of "supplementing or draining by the preference and aversions of the the five zang organs" emphasizes that prescriptions should align the five flavors of medicinals with the needs of the five organs， achieving supplementation through harmonizing flavors and drainage through opposing flavors. This paper analyzed the formulas for regulating the spleen found in Wings of the Thousand Gold Pieces Formulary （《千金翼方》） from the perspective of "supplementing or draining by the preference and aversions"， to summarize SUN Simiao's prescription characteristics for treating spleen-related disorders. In terms of the combination rule of medicinal properties and flavors， formulas like Bupi Decoction （补脾汤） for supplementing the spleen use sweet and warm medicinals paired with bitter and drying medicinals； those for draining the spleen use acrid and warm medicinals paired with bitter and cold medicinals； those for warming the spleen employs acrid and hot medicinals with sweet and warm medicinals； those like Jianpi Decoction （建脾汤） for strengthening spleen combines sweet and warm with sour and bitter medicinals； Zhuanpi Pill （转脾丸） pairs acrid and warm medicinals with sweet and warm medicinals； and Roupi Decoction （柔脾汤） uses sweet and warm medicinals with sweet and bitter medicinals. Regarding the medicinal flavors， warm dominates the four qi （the four properties）， while sweet， bitter， and acrid are the main among the five flavors. Clinical practice involves applying comprehensive therapy methods such as the combination of sweet and bitter to harmonize， acrid and sweet to transform yang， pungent to disperse and bitter to descend， balancing cold and warm， and combining supplementation and drainage. The foundational principle is to tonify spleen qi and protect the middle jiao， and treatment is tailored based on the disease condition， location， nature， and the characteristics of the medicinals， with careful selection of suitable dosage forms and administration methods.

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.

Microbial-derived metabolites are important mediators of host-microbial interactions. In recent years, the role of intestinal microbial metabolites in colorectal cancer has attracted considerable attention. These metabolites, which can be derived from bacterial metabolism of dietary substrates, modification of host molecules such as bile acids, or directly from bacteria, strongly influence the progression of colitis-associated cancer (CAC) by regulating inflammation and immune response. Here, we review how microbiome metabolites short-chain fatty acids (SCFAs), secondary bile acids, polyamines, microbial tryptophan metabolites, and polyphenols are involved in the tumorigenesis and development of CAC through inflammation and immunity. Given the heated debate on the metabolites of microbiota in maintaining gut homeostasis, serving as tumor molecular markers, and affecting the efficacy of immune checkpoint inhibitors in recent years, strategies for the prevention and treatment of CAC by targeting intestinal microbial metabolites are also discussed in this review.

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.
