The phlegm-dampness constitution is a physical state characterized by the accumulation of stagnant water and fluid in the body,leading to the formation of phlegm-dampness,a common underlying factor in various metabolic diseases.The occurrence of this metabolic disorder is closely related to the small intestine.The concept of small intestine separating purity from turbidity describes the essential functions of the small intestine in digestion,absorption,and excretion.Dysfunction of the small intestine leads to metabolic disorders of phlegm-dampness constitution through three aspects of the action of phlegm-dampness obstructing qi movement,internal accumulation of phlegm-dampness leading to damage to yang qi,and phlegm and turbidity stagnating in the small intestine without clearance.However,the microscopic mechanisms remain unclear.One key factor in metabolic regulation is incretin,an intestinal hormone secreted by endocrine cells in the small intestine,which plays an essential role in maintaining metabolic balance.Inspired by the prescription thought of national medical master WANG Qi,the Yiqi Jianyun Decoction was developed to regulate the phlegm-dampness constitution.This prescription integrates key therapeutic principles such as Banxia Xiexin Decoction,benefiting qi and warming yang,as Sijunzi Decoction with modification,which supports qi nourishment and yang warming,and rhubarb root and rhizome,which facilitates small intestine clearance.These components effectively regulate incretin levels and improve overall metabolism.This article aims to provide a new scientific interpretation of the small intestine separating purity from turbidity theory from the perspective of incretins,enriching the modern scientific connotation of the pharmacological mechanism of Yiqi Jianyun Decoction,and providing a novel theoretical basis and prescription thought for the clinical intervention of the phlegm-dampness constitution,diagnosis and treatment of metabolic diseases.

Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Objective:To explore the genes related to primary myelofibrosis (PMF) and signaling pathways as well as the possible clinical significance.Methods:A total of 3 mRNA expression datasets of PMF (GSE26049, GSE61629 and GSE53482) were downloaded from Gene Expression Omnibus (GEO) database, including the data of peripheral blood samples from 55 PMF patients and 58 controls. The differentially expressed genes (DEG) between PMF patients and the controls were identified by using online tool GEO2R. Gene ontology (GO) annotation, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis were performed on the common DEG of the 3 datasets, and then protein interaction (PPI) network was constructed. The key nodes of the common DEG in PPI network were calculated by using MCC method and Degree method in cytoHubba program; finally the top 10 hub genes were selected and the hub genes shared by the 2 methods were obtained. Peripheral blood samples of 25 PMF patients and 10 controls (normal hematopoietic stem cell transplant donors or iron deficiency anemia patients) admitted to the Second Hospital of Shanxi Medical University from September 2017 to June 2021 were retrospectively collected. Reverse transcription-fluorescence quantitative polymerase chain reaction (RT-qPCR) was used to detect the expression levels of 10 screened common hub genes in each sample, and the expressions of all genes at transcriptional level of the two groups were compared.Results:A total of 239 common DEG between PMF patients and the controls were screened out in the 3 datasets, including 153 downregulated DEG and 86 upregulated DEG. The GO enrichment analysis showed that the common downregulated DEG were significantly enriched in negative regulation of transcription, translation and fibroblast proliferation, while the upregulated DEG were mainly enriched in protein ubiquitination and ubiquitin-dependent protein catabolic process. The KEGG pathway analysis indicated that the upregulated common DEG and downregulated common DEG were both enriched in PI3K/Akt signaling pathway, cancer pathways and transcriptional misregulation in cancer. There were 8 common hub genes shared by the 2 methods among the top 10 genes ranked by MCC and Degree methods, including 6 downregulated common DEG (TP53, MYC, ATM, FYN, PTPRC and ATRX) and 2 upregulated common DEG (VEGFA and FOXO3). These above 8 common hub genes were mainly involved in PI3K/Akt signaling pathway, cell cycle and cancer transcriptional regulation signaling pathways. RT-qPCR detection of clinical peripheral blood samples showed that the relative expression levels of mRNA in 6 downregulated common DEG of PMF patients were lower compared with those in controls, while the differences were not statistically significant (all P > 0.05); the relative expression levels of mRNA in 2 upregulated common DEG of PMF patients were higher compared with those in controls, and the differences were statistically significant ( U value was 33.00, 36.00, respectively; P value was 0.021, 0.033, respectively). Conclusions:Bioinformatics and clinical sample verification show that VEGFA and FOXO3 are up-regulated in PMF patients, which are mainly involved in the PI3K/Akt signaling pathway, cell cycle and cancer transcriptional regulation signaling pathway. Both genes may be related to the development of PMF and may become potential therapeutic targets.

Objective:To investigate the prospective association of sleep duration with the development of chronic obstructive pulmonary disease (COPD) in adults in Suzhou.Methods:The study used the data of 53 269 participants aged 30-79 years recruited in the baseline survey from 2004 to 2008 and the follow-up until December 31, 2017 of China Kadoorie Biobank (CKB) conducted in Wuzhong District, Suzhou. After excluding participants with airflow limitation, self-reported chronic bronchitis/emphysema/coronary heart disease history at the baseline survey and abnormal or incomplete data, a total of 45 336 participants were included in the final analysis. The association between daily sleep duration and the risk for developing COPD was analyzed by using a Cox proportional hazard regression model, and the hazard ratio ( HR) values and their 95% CI were calculated. The analysis was stratified by age, gender and lifestyle factors, and cross-analysis was conducted according to smoking status and daily sleep duration. Results:The median follow-up time was 11.12 years, with a total of 515 COPD diagnoses in the follow-up. After adjusting for potential confounders, multifactorial Cox proportional hazard regression analysis showed that daily sleep duration ≥10 hours was associated with higher risk for developing COPD ( HR=1.42, 95% CI: 1.03-1.97). The cross analysis showed that excessive daily sleep duration increased the risk for COPD in smokers ( HR=2.49, 95% CI: 1.35-4.59, interaction P<0.001). Conclusion:Longer daily sleep duration (≥10 hours) might increase the risk for COPD in adults in Suzhou, especially in smokers.

Exosomes are cell-derived nanovesicles with diameters from 30 to 150 nm, released upon fusion of multivesicular bodies with the cell surface. They can transport nucleic acids, proteins, and lipids for intercellular communication and activate signaling pathways in target cells. In cancers, exosomes may participate in growth and metastasis of tumors by regulating the immune response, blocking the epithelial-mesenchymal transition, and promoting angiogenesis. They are also involved in the development of resistance to chemotherapeutic drugs. Exosomes in liquid biopsies can be used as non-invasive biomarkers for early detection and diagnosis of cancers. Because of their amphipathic structure, exosomes are natural drug delivery vehicles for cancer therapy.
