Metabolic reprogramming， as one of the core hallmarks of malignant tumors， plays a key role in the occurrence， development and treatment of breast cancer （BC）. Abnormal changes in glucose metabolism， amino acid metabolism， lipid metabolism， as well as the tricarboxylic acid （TCA） cycle and oxidative phosphorylation （OXPHOS） pathways significantly influence the pathogenesis and progression of BC. Studies have shown that various active components of traditional Chinese medicine （TCM） （such as berberine， matrine， quercetin， curcumin， etc.） and their compound formulations （e.g. Xihuang pill， Danzhi xiaoyao powder， Yanghe decoction， etc.） can inhibit the proliferation and migration of BC cells and induce apoptosis by regulating key metabolic pathways such as glycolysis， lipid synthesis， and amino acid metabolism. TCM demonstrates multi-target and holistic regulatory advantages in intervening in BC metabolic reprogramming， showing significant potential in modulating key molecules like hypoxia inducible factor-1α， hexokinase-2， pyruvate kinase M2， lactate dehydrogenase A， glucose transporter-1， fatty acid synthase， and signaling pathways such as AKT/mTOR. However， current researches still focus predominantly on glucose metabolism， with insufficient mechanistic studies on lipid metabolism， amino acid metabolism， the TCA cycle， and OXPHOS. The precise targets， molecular mechanisms， and clinical translation value of these interventions require further validation and clarification through more high-quality experimental studies and clinical trials.

Objective To compare imaging quality and semi-quantitative parameters of 18F-FDG whole-body images obtained with domestic NeuWise and Philips Ingenuity TF PET/CT scanners.Methods Thirty-four patients who underwent 18F-FDG whole-body scanning using NeuWise and Philips Ingenuity TF PET/CT systems respectively on the same day were enrolled.The imaging quality and semi-quantitative parameters of 2 kind images,also the mean standard uptake value(SUVmean)of normal tissue,the maximum standard uptake value(SUVmax),peak standard uptake value(SUVpeak),SUVmean of lesions,total lesion glycolysis(TLG)and metabolic tumor volume(MTV)were compared.Results No significant difference of imaging quality nor semi-quantitative parameters of lesions(all P＞0.05),while significant differences of SUVmean of aortic arch,liver,lumbar vertebra and spinal cord were found between 2 kind images(all P＜0.05).Strong correlations of SUVmax,SUVmean,MTV and TLG of lesions(r,=0.734-0.890,P＜0.001),and high correlation of SUVpeak(rs=0.919,P＜0.001)were found between 2 kind images.The consistency of SUVmax,SUVpeak,SUVmean,TLG and MTV at the lesion site between 2 kind images were very good to extremely good(ICC=0.891-0.986,all P＜0.001),and the differences of all above semi-quantitative parameters were within 95％confidence interval.Conclusion Imaging quality of 18F-FDG whole-body images obtained with domestic NeuWise and Philips Ingenuity TF PET/CT scanners could meet the requirements of clinical diagnosis and treatment,and semi-quantitative parameters obtained based on both images had good consistencies.

Objective To study the regulatory effect of Qufeng Xiaodian Formula on serum differential metabolites of allergic purpura,and provide scientific basis for the diagnosis and treatment of allergic purpura in traditional Chinese medicine.Methods Sixty rats were randomly divided into a blank control group(referred to as the blank group),a model group,a compound glycyrrhizin group,a low-dose Qu Feng Xiao Dian Fang group,a medium dose Qu Feng Xiao Dian Fang group,and a high-dose Qu Feng Xiao Dian Fang group according to a random number table method,with 10 rats in each group.The model group was constructed by combining dried ginger,pepper,and long pepper with ovalbumin to create an allergic purpura rat model.After successful modeling,each treatment group was intervened with corresponding drugs for 4 weeks.After 4 weeks,serum was collected and non targeted metabolomics screening of serum differential metabolites was performed using ultra-high performance liquid chromatography quadrupole time-of-flight tandem mass spectrometer(UPLC-QTOF/MS).Subsequently,data extraction and multivariate statistical analysis will be conducted to identify potential metabolic pathways.Results Compared with the control group,there were 91 possible differential metabolites in the serum of the model group rats,corresponding to 20 metabolic pathways;Compared with the model group,there were a total of 43 possible differential metabolites in the serum of rats in the wind dispelling and disease eliminating group,corresponding to 15 metabolic pathways.Among them,there are a total of 12 metabolic pathways.Inflammatory metabolites such as arachidonic acid and ceramide can damage vascular endothelium.Ten biomarkers,including arachidonic acid and ceramide,were significantly abnormal in the serum of the model group rats compared to the normal group.The Qufeng Xiaodian formula can significantly reverse these metabolites and significantly enrich them in arachidonic acid metabolism and sphingolipid metabolism pathways.Conclusion Qufeng Xiaodian Formula has a certain regulatory effect on metabolites such as arachidonic acid and ceramide that affect vascular endothelial injury.

Objective:To improve the understanding of recurrent adult Langerhans cell histiocytosis complicated with diabetes insipidus.Methods:The clinical data of 1 patient with recurrent adult Langerhans cell histiocytosis complicated with diabetes insipidus admitted to the First Affiliated Hospital of Shihezi University in January 2024 was collected. Its disease characteristics, effectiveness and safety of treatment scheme were analyzed, and literatures were reviewed.Results:The 42-year-old female patient was diagnosed as Langerhans cell histiocytosis in June 2021. After treated with cytarabine, the symptoms improved and the patient achieved sustained remission. In January 2024, the patient was admitted to the hospital due to pain in the middle part of the front chest. The PET-CT results indicated disease progression, which was manifested by new bone destruction, enlarged lymph nodes, and increased nocturnal urination, with urine volume of 3-5 L within 24 h. Based on the clinical manifestations such as cranial bone lesions, periorbital soft tissue lesions, and enlarged lymph nodes at onset, multiple systems and multiple foci involvement was considered. The diagnosis of combined diabetes insipidus was confirmed through the water deprivation and pressure test. After MACOP-B regimen (doxorubicin liposome, cyclophosphamide, vincristine, bleomycin, prednisone), the patient's bone pain was completely relieved, and no serious complications occurred.Conclusions:Recurrent adult Langerhans cell histiocytosis complicated with diabetes insipidus is rare; MACOP-B regimen is safe and effective in treatment of the disease.

BACKGROUND: Electroacupuncture (EA) treatment is efficacious in patients with respiratory disorders, although the mechanisms of its action in lung-function protection are poorly understood. This study aimed to explore the neuroanatomical mechanisms of EA stimulation at the BL13 acupoint (Feishu, EA-BL13) improvement in asthma. METHODS: Allergic asthma was induced by intranasal 2.0% ovalbumin (OVA) instillation combined with intraperitoneal injection of the 10.0% OVA. The levels of interleukin (IL)-4 and IL-5 were detected by enzyme-linked immunosorbent assay. Hematoxylin and eosin and periodic acid-schiff stain were used to evaluate inflammatory cell infiltration and mucus secretion. Cellular oncogene fos induction in neurons after EA stimulation was detected by immunofluorescent staining. The messenger RNA expression levels of adrenergic receptors were quantified with real-time polymerase chain reaction. RESULTS: EA improved airway inflammation and mucus secretion mainly by activating somatosensory-sympathetic pathways ( P <0.001). Briefly, the intermediolateral (IML) nuclei of the spinal cord received signals from somatic EA stimulation and then delivered the information via the sympathetic trunk to the lung. Excited sympathetic nerve endings in lung tissue released large amounts of catecholamines that specifically activated the β2 adrenergic receptor (β2AR) on T cells ( P <0.01) and further decreased the levels of IL-4 and IL-5 ( P <0.001) through the cyclic adenosine monophosphate/protein kinase A signaling pathway. CONCLUSION This study provided a new explanation and clinical basis for the use of EA-BL13 as a treatment for allergic asthma in both the attack and remission stages and other respiratory disorders related to airway inflammation.
