Purpose:
We used bioinformatics methods and Mendelian randomization (MR) analysis to investigate the hub genes involved in acute myeloid leukemia (AML) and their causal relationship with hemolysis, to explore a new direction for molecular biology research of AML.
Methods:
We first differentially analyzed peripheral blood samples from 62 healthy volunteers and 65 patients with AML from the Gene Expression Omnibus database to obtain differentially expressed genes (DEGs), and intersected them with genes sourced from weighted gene co-expression network analysis (WGCNA) and the GeneCards database to obtain target genes. Target genes were screened using protein–protein interaction (PPI) network analysis and ROC curves to identify genes associated with AML. Finally, we analyzed the correlation between genes and immune cells and the relationship between toll-like receptor 4 (TLR4) and AML using MR.
Results:
We compared peripheral blood expression profiles using an array of 62 healthy volunteers (GSE164191) and 65 patients with AML (GSE89565) (M0:25; M1:11; M2:10; M3:1; M4:7; M4 eo t [16;16] ou inv [16]:4; M5:6; M6:1) and obtained 7,339 DEGs (3,733 upregulated and 3,606 downregulated). We intersected these DEGs with 4,724 genes from WGCNA and 1,330 genes related to hemolysis that were identified in the GeneCards database to obtain 190 target genes. After further screening these genes using the PPI network, we identified TLR4, PTPRC, FCGR3B, STAT1, and APOE, which are closely associated with hemolysis in patients with AML. Finally, we found a causal relationship between TLR4 and AML occurrence using MR analysis (p < 0.05).
Conclusion
We constructed a WGCNA-based co-expression network and identified hemolysis-associated AML genes.

Objective To compare the mid- and long-term clinical results of mitral valve plasty (MVP) and mitral valve replacement (MVR) in the treatment of functional mitral regurgitation (FMR). Methods Patients with FMR who underwent surgical treatment in the Department of Cardiovascular Surgery of the General Hospital of Northern Theater Command from 2012 to 2021 were collected. The patients who underwent MVP were divided into a MVP group, and those who underwent MVR into a MVR group. The clinical data and mid-term follow-up efficacy of two groups were compared. Results Finally 236 patients were included. There were 100 patients in the MVP group, including 53 males and 47 females, with an average age of (61.80±8.03) years. There were 136 patients in the MVR group, including 72 males and 64 females, with an average age of (61.29±8.97) years. There was no statistical difference in baseline data between the two groups (P>0.05). There was no statistical difference between the two groups in the extracorporeal circulation time, aortic occlusion time, postoperative hospital and ICU stay, intraoperative blood loss, or hospitalization death (P>0.05), but the time of mechanical ventilation in the MVP group was significantly shorter than that in the MVR group (P=0.022). The total follow-up rate was 100.0%, the longest follow-up was 10 years, and the average follow-up time was (3.60±2.55) years. There were statistical differences in the left atrial diameter, left ventricular end-diastolic diameter, left ventricular end-systolic diameter and cardiac function between the two groups compared with those before surgery (P<0.05). The postoperative left ventricular ejection fraction in the MVP group was statistically higher than that before surgery (P=0.002), but there was no statistical difference in the MVR group before and after surgery (P=0.658). The left atrial diameter in the MVP group was reduced compared with the MVR group (P=0.026). The recurrence rate of mitral regurgitation in the MVP group was higher than that in the MVR group, and the difference was statistically significant (10.0% vs. 1.5%, P=0.003). There were 14 deaths in the MVP group and 19 in the MVR group. The cumulative survival rate (P=0.605) and cardiovascular events-free survival rate (P=0.875) were not statistically significant between the two groups by Kaplan-Meier survival analysis. Conclusion The safety, and mid- and long-term clinical efficacy of MVP in the treatment of FMR patients are better than MVR, and the left atrial and left ventricular diameters are statistically reduced, and cardiac function is statistically improved. However, the surgeon needs to be well aware of the indications for the MVP procedure to reduce the rate of mitral regurgitation recurrence.

The European Society of Cardiology (ESC) released the "2024 ESC guidelines for the management of elevated blood pressure and hypertension" on August 30, 2024. This guideline updates the 2018 "Guidelines for the management of arterial hypertension." One notable update is the introduction of the concept of "elevated blood pressure" (120-139/70-89 mm Hg). Additionally, a new systolic blood pressure target range of 120-129 mm Hg has been proposed for most patients receiving antihypertensive treatment. The guideline also includes numerous additions or revisions in areas such as non-pharmacological interventions and device-based treatments for hypertension. This article interprets the guideline's recommendations on definition and classification of elevated blood pressure and hypertension, and cardiovascular disease risk assessment, diagnosing hypertension and investigating underlying causes, preventing and treating elevated blood pressure and hypertension. We provide a comparison interpretation with the 2018 "Guidelines for the management of arterial hypertension" and the "2017 ACC/AHA guideline on the prevention, detection, evaluation, and management of high blood pressure in adults."

Pancreatic cancers (PCs) is a common malignant tumor with poor prognosis in the digestive system. Its main treatment methods include surgery, radiotherapy, chemotherapy, and targeted therapy. The early diagnosis rate of hidden onset of PCs is low, and most patients have already lost the opportunity to undergo surgery when diagnosed with PCs. Chemotherapy is still the main treatment for advanced PCs, but the use of chemotherapy drugs in PCs can easily lead to drug resistance. The most significant feature that distinguishes PCs from other tumors is its rich and dense matrix, which not only hinders drug penetration but also impedes the infiltration of immune cells. The above reasons have led to a very low survival rate of PCs patients. Therefore, drug delivery systems are very important in the diagnosis and treatment of PCs. They can improve drug delivery, enhance biological barrier penetration, reduce side effects, and combine multiple treatment methods. Therefore, the treatment prospects of PCs are very broad. Currently, drug delivery systems widely applied in PCs primarily include nanodrug delivery systems, tumor microenvironment-targeted drug delivery system, immunotherapy drug delivery system, gene therapy drug delivery system, and combination therapy drug delivery system that synergize multiple therapeutic modalities. Emerging drug delivery systems (DDSs) have revolutionized PCs treatment by addressing these challenges through multiple mechanisms. Nanoformulations improve drug solubility, prolong circulation time, and reduce systemic toxicity via passive/active targeting. Smart DDSs responsive to PCs-specific stimuli enable extracellular matrix degradation, tumor-associated fibroblasts reprogramming, and vascular normalization to enhance drug accessibility. Last but not least, carrier systems loaded with myeloid-derived suppressor cell inhibitors or T cell activators can reverse immunosuppression and potentiate immunotherapy efficacy. Advanced platforms co-deliver chemotherapeutics with immunomodulators, gene-editing tools, or sonodynamic agents to achieve synergistic antitumor effects. These platforms aim to address critical challenges in PCs treatment, such as enhancing drug bioavailability, overcoming stromal barriers, reprogramming immunosuppressive niches, and achieving multi-mechanistic antitumor effects. This article provides a systematic summary and prospective analysis of the current development status, latest cutting-edge advances, opportunities, and challenges of the above-mentioned drug delivery systems in the field of PCs therapy.

Aim To evaluate the effect of Pien Tze Huang(PTH)on influenza virus susceptibility in re-straint stress-induced H1N1 influenza susceptibility model in mice with emotional disorders and internal heat,guided by the theory of emotional pathogenesis.Methods Mice were infected with H1N1 influenza vi-rus following 18 h of restraint stress.The signs and weight changes of mice were recorded,and the morbid-ity of mice were analyzed.On the fourth day post viral infection,the lung tissue was collected.The pathologi-cal changes and inflammatory factors in lungs were de-tected by HE staining.The expression of NP was as-sessed by immunohistochemistry and Western blot.The level of lipid peroxidation end products was detected u-sing a commercial kit and western blot.Redox phos-pholipidomics was analyzed in lung tissue by HPLC-MS/MS.Results PTH significantly reduced the mor-tality of influenza-susceptible mice induced by emotion-al stress,inhibited the expression of NP and the re-lease of inflammatory factors,improved inflammation in lung tissue,and alleviated the accumulation of lipid peroxidation end products.Phospholipid oxidation a-nalysis revealed the elevated levels of oxidized phos-pholipid choline and phosphatidylethanolamine in lung tissue of influenza-susceptible mice,which were signif-icantly reduced by PTH administration.Conclusions PTH exhibits promising efficacy in ameliorating influ-enza virus susceptibility induced by internal heat,and its mechanism of action may be related to the regulation of phospholipid peroxidation.

Objective:To explore the electrophysiological characteristics of patients with prolonged disorders of conscious-ness responded to transcranial direct current stimulation(tDCS)intervention by a hierarchical auditory event-re-lated potential(ERP)Oddball pattern. Method:A hierarchical auditory ERP pattern was applied to seventeen unresponsive wakefulness syndrome(UWS)and thirty-one minimally conscious state(MCS)patients who subsequently received 20 anodal tDCS sessions of the left dorsolateral prefrontal cortex(DLPFC)over 10 consecutive working days.The patients were divided into responders and non-responders according to the Coma Recovery Scale-Revised(CRS-R)be-havioral evaluation,and the differences in general conditions and electrophysiological characteristics were com-pared. Result:Univariable analysis showed that the responders and non-responders did not differ for gender,age,time since onset,operation,CRS-R score and the proportion of P300(P>0.05)in UWS patients.In MCS pa-tients,CRS-R score(P=0.015)and P300 in DO paradigm(P=0.005)were independently associated with tDCS response,while gender,age,time since onset,operation and P300 in TO paradigm were not associated with responsiveness(P>0.05). Conclusion:Higher CRS-R total score and presence of P300 in the hierarchical auditory ERP pattern,especial-ly P300 in the DO paradigm,are associated with tDCS response in MCS patients.P300 in the DO paradigm may indicate that these patients possess higher levels of preserved semantic processing capabilities,and had a priority to recover.

Spontaneous subarachnoid hemorrhage(sSAH)is one of the common critical illnesses in neurosurgery,and still has a high rate of death and disability.For these patients,computed tomographic angiography(CTA)or digital subtraction angiography(DSA)should be performed as soon as possible to identify the cause and location of the hemorrhage,and surgery should be performed as soon as possible according to the identified cause.This is particularly important to improve the prognosis of patients.However,some patients have false-negative first-time angiograms for a variety of reasons,such as perimesencephalic subarachnoid hemorrhage,microaneurysms,thrombotic aneurysms,intracranial vascular malformations,spinal vascular malformations,and the experience of the radiologists.Patients with a negative first imaging must be followed up,especially in patients with a high suspicion of aneurysm on CT scanning of the head after onset.The time of the reexamination is recommended to be in the early(<2 weeks)and mid-term(2-8 weeks)stages after the disease,and to increase the vigilance and ability to recognize microvascular lesions,and to improve the ability of first-time detection of the cause with the help of the latest imaging techniques.
