Regrettably, a significant number of patients still progress to relapse/refractory DLBCL (rrDLBCL).Methods: Herein, we employed targeted sequencing of 55 genes to investigate if gene mutations could predict the progression to rrDLBCL. Additionally, we compared the mutation profiles at the time of DLBCL diagnosis with those found in rrDLBCL cases.Results: Our findings highlighted significantly elevated mutation frequencies of TP53, MEF2B and CD58 in diagnostic biopsies from patients who progressed to relapse or refractory disease, with CD58 mutations exclusively observed in the rrDLBCL group. In assessing the predictive power of mutation profiles for treatment responses in primary DLBCL patients, we found that the frequency of CARD11 mutations was substantially higher in non-response group as compared with those who responded to immunochemotherapy. In addition, we revealed mutations in HIST2H2AB, BCL2, NRXN3, FOXO1, HIST1H1C, LYN and TBL1XR1 genes were only detected in initial diagnostic biopsies, mutations in the EBF1 gene were solely detected in the rrDLBCL patients.Conclusion: Collectively, this study elucidates some of the genetic mechanisms contributing to the progression of rrDLBCL and suggests that the presence of CD58 mutations might serve as a powerful predictive marker for relapse/refractory outcomes in primary DLBCL patients.Keywords: targeted sequencing, mutation profile, relapse/refractory disease, diffuse large B-cell lymphoma

This study aims to identify key indicators influencing the efficacy of amlodipine, thereby enhancing treatment outcomes.Patients and Methods: In this multicenter retrospective study, 870 hospitalized patients with primary hypertension exclusively received amlodipine for the first 5 days after admission, and their medical records contained comprehensive blood pressure records. They were categorized into success (n=479) and failure (n=391) groups based on average blood pressure control efficacy. Predictive models were constructed using six machine learning algorithms. Evaluation metrics encompassed the area under the curve (AUC), accuracy, sensitivity, specificity, positive predictive value (PPV), and negative predictive value (NPV). SHapley Additive exPlanations (SHAP) analysis assessed feature contributions to efficacy.Results: All six machine learning models demonstrated superior predictive performance. Following variable reduction, the model predicting amlodipine efficacy was reconstructed using these algorithms, with the light gradient boosting machine (LightGBM) model achieving the highest overall performance (AUC = 0.803). Notably, amlodipine showed enhanced efficacy in patients with low platelet distribution width (PDW) values, as well as high hematocrit (HCT) and thrombin time (TT) values.Conclusion: This study utilized machine learning to predict amlodipine’s effectiveness in hypertension treatment, pinpointing key factors: HCT, PDW, and TT levels. Lower PDW, along with higher HCT and TT, correlated with enhanced treatment outcomes. This facilitates personalized treatment, particularly for hospitalized hypertensive patients undergoing amlodipine monotherapy.Keywords: anti-hypertensive drugs, hypertension, machine learning, shapley additive explanations

Fullerenols, a type of carbon nanomaterial known for its neuroprotective properties, have not yet been studied for their potential in treating ASD. We aimed to investigate its role in improving autistic behaviors in BTBR T+Itpr3tf/J (BTBR) mice and its underlying mechanism, which could provide reliable clues for future ASD treatments.Methods: Our research involved treating C57BL/6J (C57) and BTBR mice with either 0.9% NaCl or fullerenols (10 mg/kg) daily for one week at seven weeks of age. We then conducted ASD-related behavioral tests in the eighth week and used RNA-seq to screen for vital pathways in the mouse hippocampus. Additionally, we used real-time quantitative PCR (RT-qPCR) to verify related pathway genes and evaluated the number of stem cells in the hippocampal dentate gyrus (DG) by Immunofluorescence staining.Results: Our findings revealed that fullerenols treatment significantly improved the related ASD-like behaviors of BTBR mice, manifested by enhanced social ability and improved cognitive deficits. Immunofluorescence results showed that fullerenols treatment increased the number of DCX+ and SOX2+/GFAP+ cells in the DG region of BTBR mice, indicating an expanded neural progenitor cell (NPC) pool of BTBR mice. RNA-seq analysis of the mouse hippocampus showed that VEGFA was involved in the rescued hippocampal neurogenesis by fullerenols treatment.Conclusion: In conclusion, our findings suggest that fullerenols treatment improves ASD-like behavior in BTBR mice by upregulating VEGFA, making nanoparticle- fullerenols a promising drug for ASD treatment.

However, the mechanism and function of circ_0007386 in HCC are still unknown.Methods: Circ_0007386 expression level in HCC tissues, and HCC cell lines was further analyzed by qRT-PCR. Agarose gel electrophoresis and Sanger sequencing were used to figure out the structure of circ_0007386. The involvement of circ_0007386 in HCC development was evaluated by experimental investigations conducted in both laboratory settings (in vitro) and living organisms (in vivo). RNA immunoprecipitation, Western blotting, luciferase reporter assay and fluorescence in situ hybridization (FISH) were applied for finding out the interaction among circ_0007386, miR-507 and CCNT2. To assess the connection between circ_0007386 and lenvatinib resistance, lenvatinib-resistant HCC cell lines were employed.Results: The expression of circ_0007386 was found to increase in HCC tissues, and it was observed to be associated with a worse prognosis. Overexpression of circ_0007386 stimulated HCC cells proliferation, invasion, migration and the epithelial–mesenchymal transition (EMT) while silencing of circ_0007386 resulted in the opposite effect. Mechanistic investigations revealed that circ_0007386 acted as a competing endogenous RNA of miR-507 to prevent CCNT2 downregulation. Downregulating miR-507 or overexpressing CCNT2 could reverse phenotypic alterations that originated from inhibiting of circ_0007386. Importantly, circ_0007386 determines the resistance of hepatoma cells to lenvatinib treatment.Conclusion: Circ_0007386 advanced HCC progression and lenvatinib resistance through the miR-507/ CCNT2 axis. Meanwhile, circ_0007386 served as a potential biomarker and therapeutic target in HCC patients. Keywords: hepatocellular carcinoma, circ_0007386, miR-507, CCNT2, Lenvatinib

The patients were randomized 3:1 to the training and validation sets. The risk factors for hypoglycemia were analyzed. A prediction model was developed.Results: This study included 122 patients, and 57 patients had at least one hypoglycemic event during their hospitalization (46.72%). The multivariable logistic regression analysis showed that the time to reach the glycemic targets (odds ratio (OR)=1.408, 95% confidence interval (CI)=1.084– 1.825, P=0.006), average glycemia (OR=0.387, 95% CI=0.233– 0.643, P=0.010), coronary heart disease (OR=0.089, 95% CI=0.016– 0.497, P< 0.001), and the administration of hormone therapy (OR=6.807, 95% CI=1.128– 41.081, P=0.037) were independently associated with hypoglycemia. A nomogram was built. The receiver operating characteristics analysis showed that the area under the curve of the model was 0.872 (95% CI=0.0.803– 0.940) for the training set and 0.839 (95% CI=0.688– 0.991) in the validation set.Conclusion: A nomogram was successfully built to predict hypoglycemia in T2DM patients treated with an insulin pump during enteral nutrition, based on the time to reach the glycemic targets, average glycemia, coronary heart disease, and the administration of hormone therapy.Keywords: T2DM, hypoglycemia, enteral nutrition, insulin pump therapy, nomograms

The Chinese herbal formula Radix Rehmanniae Praeparata- Angelica Sinensis-Radix Achyranthis Bidentatae (RAR) has often been used in effective prescriptions for KOA as the main functional drug, but its underlying mechanism remains unclear. Therefore, network pharmacology and verification experiments were employed to investigate the impact and mode of action of RAR in the treatment of KOA.Methods: The destabilization of the medial meniscus model (DMM) was utilized to assess the anti-KOA effect of RAR by using gait analysis, micro-computed tomography (Micro-CT), and histology. Primary chondrocytes were extracted from the rib cartilage of a newborn mouse. The protective effects of RAR on OA cells were evaluated using a CCK‐8 assay. The antioxidative effect of RAR was determined by measuring reactive oxygen species (ROS), superoxide dismutase (SOD), and glutathione (GSH) production. Furthermore, network pharmacology and molecular docking were utilized to propose possible RAR targets for KOA, which were further verified through experiments.Results: In vivo, RAR significantly ameliorated DMM-induced KOA characteristics, such as subchondral bone sclerosis, cartilage deterioration, gait abnormalities, and the degree of knee swelling. In vitro, RAR stimulated chondrocyte proliferation and the expression of Col2a1, Comp, and Acan. Moreover, RAR treatment significantly reduced ROS accumulation in an OA cell model induced by IL-1β and increased the activity of antioxidant enzymes (SOD and GSH). Network pharmacology analysis combined with molecular docking showed that Mapk1 might be a key therapeutic target. Subsequent research showed that RAR could downregulate Mapk1 mRNA levels in IL-1β-induced chondrocytes and DMM-induced rats.Conclusion: RAR inhibited extracellular matrix (ECM) degradation and oxidative stress response via the MAPK signaling pathway in KOA, and Mapk1 may be a core target.Keywords: knee osteoarthritis, RAR, cartilage degeneration, network pharmacology, Mapk1

The etiology, pathogenesis, and optimal treatment strategies for this condition remain undetermined. The occurrence of spontaneous spinal epidural hematoma (SSEH) in the context of JAK2 V617F-positive myeloproliferative neoplasms (MPNs) represents a rare manifestation. Magnetic Resonance Imaging (MRI) plays a crucial role in the definitive diagnosis of this condition. With a good understanding of the pathogenic characteristics and clinical presentations of this disease, a diagnosis can be reasonably made, even in the absence of MRI, based on physical examinations indicating the affected area. Once diagnosed, immediate surgery is recommended to attempt the restoration of spinal cord function. Postoperatively, the use of hydroxyurea has proven effective in disease control.Case Presentation: We report a case of a 65-year-old male patient who presented with progressive lumbar back pain and bilateral lower limb paralysis lasting for 36 hours. CT imaging revealed an intraspinal lesion at the L1-3 level, and genetic testing confirmed the presence of the JAK2V617F mutation. Following surgery, there was a significant recovery of sensory and motor function in the lower limbs. At one-year follow-up, the patient demonstrated good functional status, and blood tests indicated a platelet count within the normal range.Conclusion: The presented case adds to the existing literature on SSEH by highlighting the association with myeloproliferative neoplasms (MPNs), as evidenced by the JAK2V617F mutation. MPNs constitute a group of hematologic malignancies, and the association with SSEH is a rare occurrence. The exact interplay between MPNs and SSEH warrants further investigation, as the underlying mechanisms linking these conditions remain elusive. The case also underscores the importance of a multidisciplinary approach, involving hematologists and neurosurgeons, in the comprehensive management of such complex cases.Keywords: myeloproliferative neoplasms, spinal epidural hematoma, JAK2V617F

Pancreatic involvement in VHL syndrome can present as endocrine tumors and pancreatic cysts, which can interfere with both exocrine and endocrine functions of the pancreas. Diabetes is an uncommon complication of VHL syndrome.Purpose: This study aims to summarize the various mechanisms of diabetes in VHL syndrome by reporting two cases and conducting a literature review.Methods: We analyzed the clinical and imaging data of two patients with VHL syndrome and diabetes. Additionally, we reviewed the existing literature to explore the clinical diversities and management strategies for VHL syndrome complicated with diabetes.Results: The first patient presented with liver metastasis of pancreatic neuroendocrine tumor and multiple pheochromocytoma. After surgery, the patient’s diabetic control improved, as evidenced by a significant reduction in insulin dosage. This indicates a potential insulin resistance due to elevated metanephrine levels prior to surgery and partial insulin deficiency caused by distal pancreatectomy. The second patient had multiple hemangioblastomas, as well as multiple pancreatic cysts and positive pancreatic islet autoantibodies. Diabetes in this case may be attributed to pancreatic lesions and the coexistence of autoimmune insulitis. A literature review of other patients with VHL combined with diabetes revealed multiple mechanisms, including increased catecholamine levels, pancreatic lesions, surgical removal of pancreatic tissue, endocrine treatment, and possibly the coexistence of autoimmune insulitis.Conclusion: VHL syndrome complicated with diabetes involves diverse mechanisms.Keywords: von Hippel-Lindau syndrome, diabetes, pancreatic neuroendocrine tumor

This survey reports physicians’ understanding and incidence rate of breakthrough cancer pain (BTCP). The choice of analgesics and satisfaction of analgesic effect were investigated. We also investigated doctors’ knowledge of the diagnostic criteria for RCP and their tendency to choose analgesics. Oral immediate-release morphine and intravenous or subcutaneous morphine injection have been the common treatment approach for transient cancer pain exacerbations. The main barriers to pain management are lack of standardized treatment methods for RCP, lack of knowledge related to RCP, and single drug dosage form. Doctors believe the most necessary measures to improve the current situation of poor cancer pain control include improving medical staff’s understanding and treatment techniques for RCP, updating treatment techniques and methods, and improving the configuration of drug types in medical institutions. Clinicians expect to improve understanding and treatment techniques through systematic training.Conclusion: Despite multiple available analgesic measures, the treatment of RCP remains challenging. Improving the understanding of medical staff towards RCP, improving treatment techniques, and increasing the accessibility of multiple drug types are important ways to improve the satisfaction of cancer pain management in the future.Keywords: refractory cancer pain, breakthrough cancer pain, pain management, opioid drugs

Magnetic graphene oxide (MGO) nanocomposites with the excellent physicochemical properties have great potential in bone tissue engineering. In this study, we aim to explore the craniomaxillofacial bone defect repairment effect of MGO nanocomposites and its underlying mechanism.Methods: The biocompatibility of MGO nanocomposites was verified by CCK8, live/dead staining and cytoskeleton staining. The function of MGO nanocomposites induced osteogenic differentiation of BMSCs was investigated by ALP activity detection, mineralized nodules staining, detection of osteogenic genes and proteins, and immune-histochemical staining. BMSCs with or without MGO osteogenic differentiation induction were collected and subjected to high-throughput circular ribonucleic acids (circRNAs) sequencing, and then crucial circRNA circAars was screened and identified. Bioinformatics analysis, Dual-luciferase reporter assay, RNA binding protein immunoprecipitation (RIP), fluorescence in situ hybridization (FISH) and osteogenic-related examinations were used to further explore the ability of circAars to participate in MGO nanocomposites regulation of osteogenic differentiation of BMSCs and its potential mechanism. Furthermore, critical-sized calvarial defects were constructed and were performed to verify the osteogenic differentiation induction effects and its potential mechanism induced by MGO nanocomposites.Results: We verify the good biocompatibility and osteogenic differentiation improvement effects of BMSCs mediated by MGO nanocomposites. Furthermore, a new circRNA-circAars, we find and identify, is obviously upregulated in BMSCs mediated by MGO nanocomposites. Silencing circAars could significantly decrease the osteogenic ability of MGO nanocomposites. The underlying mechanism involved circAars sponging miR-128-3p to regulate the expression of SMAD5, which played an important role in the repair craniomaxillofacial bone defects mediated by MGO nanocomposites.Conclusion: We found that MGO nanocomposites regulated osteogenic differentiation of BMSCs via the circAars/miR-128-3p/SMAD5 pathway, which provided a feasible and effective strategy for the treatment of craniomaxillofacial bone defects.

Indicators of therapeutic efficacy and prognosis were objective response rate (ORR), disease control rate (DCR), and time to progression (TTP).Results: The baseline sHER2 level was high in 132 patients and low in 68 patients. The high level of sHER2 is correlated with molecular subtype (p=0.016), visceral metastasis (p< 0.001), liver metastasis (p< 0.001), tissue HER-2 (tHER2) (p=0.001), and, among tHER2-low tumors (59 patients), the baseline sHER2 high level was associated with a higher proportion of brain metastasis. The ORR of patients with baseline sHER2 high level is higher than those with baseline sHER2 low level (p=0.026). The TTP of patients with baseline sHER2 low level is longer than the patients with baseline sHER2 high level (p=0.024). For patients with baseline sHER2 high level, a significant decrease in sHER2 after two cycles of treatment indicates higher ORR, DCR, and an extension of TTP. After multiple cycles of treatment, for patients with tHER-2 positive and baseline sHER2 high level, the DCR in the sHER2 decrease in the negative group was higher than that in the continuous positive group (p=0.037). Patients with a rapid decline type of sHER2 dynamic change curve had higher ORR and prolonged TTP compared with patients with other types of sHER2 dynamic change curve. There is no correlation between OS and sHER2 levels.Conclusion: Our study showed that patients with advanced breast cancer had a high level of sHER2 at recurrence, regardless of whether they are tHER2 positive or negative. Dynamic detection of sHER2 can help predict therapeutic efficacy and prognosis, regardless of whether tHER-2 is positive or negative.Keywords: serum HER2, advanced breast cancer, clinicopathological characteristics, therapeutic efficacy, prognosis

In this two-stage, single-center, non-randomized controlled trial, we investigated the benefits of combining Chinese traditional herbal treatment with csDMARDs to aid GC discontinuation in terms of GC tapering, disease control, and safety. A total of 231 participants were enrolled, of which 150 eligible subjects were included in the first phase and allocated to three groups (control group, treatment group 1, and treatment group 2) based on their willingness to take traditional Chinese medicine and syndrome differentiation, in a 1:1:1 ratio. All groups received basic treatment consisting of methotrexate tablets (10 mg, qw), leflunomide (10 mg, qd), and stratified GC bridging therapy and tapering regimen (The intervention regimen was developed based on rigorous adherence to available evidence). Treatment group 1 received basic treatment combined with Juanbi Granule, while treatment group 2 received basic treatment combined with Yupingfeng Guizhi Decoction Granule. Efficacy was evaluated after a 12-week follow-up, with slightly adjustments to the treatment group based on efficacy and change of syndrome, followed by continued observation until 24 weeks to complete the study. The efficacy evaluation and data analysis were conducted in a blinded manner, including group label concealment, data cleaning, confounder and control regimen analysis, and outcome analysis. This project has received ethical approval from the Ethics Committee of Yunnan Provincial Hospital of Traditional Chinese Medicine (YLZ [2022] Ethical Review No. (006)-01) and has been registered with the China Clinical Trials Registry (Registration number: ChiCTR2300067676, Registered 17 January 2023, https://www.chictr.org.cn/showproj.html?proj=184908). This trial was the first to evaluate the clinical efficacy of combining Chinese herbal medicines with standard Western medicines to facilitate the discontinuation of glucocorticoid (GC) therapy in patients with rheumatoid arthritis (RA).Keywords: rheumatoid arthritis, glucocorticoids tapering, clinical trial, traditional Chinese medicine, Yupingfeng Guizhi Decoction, Juanbi Decoction

From January 2016 to September 2022, 96 patients who underwent percutaneous endoscopic lumbar discectomy for L4/5 rLDH after PETD were enrolled in the study. Based on the revision approach, the patients were divided into PETD group (57 cases) and percutaneous endoscopic interlaminar discectomy (PEID) group (39 cases). Visual Analogue Scale (VAS) for back and leg pain, Oswestry Disability Index (ODI), and modified MacNab standard were recorded to evaluate the clinical outcomes.Results: No significant differences were found in the demographic data and intraoperative blood loss between the two groups (P> 0.05), but the time of operation and intraoperative X-ray fluoroscopy exposures in the PEID group were significantly less than that in the PETD group (P< 0.05). The patients’ postoperative clinical indexes gradually improved, and the VAS score, ODI index, and JOA score of the patients in both groups showed significant improvement compared with the preoperative period at the 1-week, 1-month, and 6-month postoperative follow-ups (P < 0.05). There was no serious complication observed during the follow-up.Conclusion: For recurrent LDH after PETD of L4/5 segments, percutaneous endoscopic revision can achieve satisfactory results. Among them, PEID has a shorter operative and fluoroscopy time and allows avoidance of the scar that forms after the initial surgery, so it can be considered preferred when both procedures can remove the disk well. However, for some specific types of herniation, a detailed surgical strategy is required.Keywords: endoscopic revision, recurrent lumbar disc herniation, percutaneous endoscopic lumbar discectomy

The clinical infectiousness, pathogenicity, and resistance mechanisms of C. gilardii are still unclear due to the lack of clinical and sequencing data. We need to obtain insight into the clinical characteristics, virulence, and resistance mechanisms of C. gilardii.Patients and Methods: We isolated five C. gilardii isolates from hospitalized patients and carried out assay, culture and genome sequencing. We analyzed the genomic features of clinical C. gilardii isolates and took insight into their clinical characteristics, virulence, and resistance mechanisms.Results: These isolates were resistant to meropenem, gentamicin, and other antimicrobials due to intrinsic resistance genes. Furthermore, the sequencing results revealed the widespread presence of the MCR-5.1 gene in C. gilardii. The virulence magnitude of C. gilardii is closely correlated with the number of virulence factors they carry. Some C. gilardii strains can acquire resistance to levofloxacin through gyrA gene mutation during treatment. The diverse antimicrobial resistance mechanisms challenge the treatment of C. gilardii infections.Conclusion: We present the genomic characteristics of clinically isolated C. gilardii to improve (i) our understanding of this pathogen and (ii) treatment options.Keywords: Cupriavidus gilardii, clinical characteristics, antimicrobial resistance, MCR-5.1, gyrA

The levels of hematological parameters during pregnancy can reflect inflammatory conditions in pregnant women. This study aims to describe the dynamic change of blood cell parameters from the first trimester (6– 12 weeks of gestation) to the second trimester (24– 28 weeks of gestation) and to investigate the associations of these biomarkers with the risk of GDM.Methods: This study was a prospective double-center study conducted in Beijing, China (clinical trial number: NCT03246295). Hematological parameters were tested four times during the follow-up. Logistic regression analysis and Receiver Operating Characteristic (ROC) curve analysis were used to explore the association and predictive ability of hematological parameters for GDM.Results: There were 258 of 1027 pregnant women in our study developed GDM. Among the 1027 pregnant women, white blood cells (WBC) gradually increased, and red blood cells (RBC), hemoglobin (HGB), and platelet (PLT) tended to decrease from the first trimester to second trimester. After adjusting for confounding factors, higher levels of RBC, HGB, and PLT in both early and middle pregnancy were positively associated with GDM risk, whereas the level of WBC was associated with GDM risk only in early pregnancy. WBC, RBC, HGB, and PLT in early and middle pregnancy were all correlated with fasting insulin (FINS) in early pregnancy.Conclusion: Higher levels of hematological parameters in early and middle pregnancy were associated with glucose metabolism in early pregnancy and the subsequent risk of GDM.Keywords: hematological parameters, gestational diabetes mellitus, inflammation, insulin resistance, prospective study

The respiratory event index (REI) derived from OWSA and the apnea-hypopnea index (AHI) provided by PSG were compared. SHapley Additive exPlanation (SHAP) values were calculated to explain the model of OWSA.Results: The OWSA-REI (26.5± 18.5 events/h) correlated well with PSG-AHI (33.2± 25.7 events/h; r = 0.91, p < 0.001), with an intraclass correlation coefficient (ICC) of 0.83. Using a threshold of AHI ≥ 15 events/h, the sensitivity, specificity, accuracy, and area under the curve (AUC) were 86.1%, 86.7%, 86.3%, and 0.94, respectively. Bland-Altman analysis showed that OWSA-REI and PSG-AHI were in good agreement (Mean Difference: − 6.7, 95% CI:16.0 to − 29.3 events/h). In addition, the effectiveness of the models in OWSA were also explained by visualizing SHAP values.Conclusion: The OWSA demonstrated a reasonable performance for OSA screening in the clinical setting. In light of this, it is possible for smartwatches to become a complementary tool to PSG, which is particularly useful for larger-scale preliminary screenings.Plain Language Summary: OPPO Watch Sleep Analyzer (OWSA), an emerging sleep-tracking method based on a wearable device, uses a machine learning model to analyze physiological signals including snoring recordings, and other basic anthropometric information to estimate REI. The study evaluated the OSA screening performance of OWSA with PSG-AHI and interpreted the results of the pre-trained machine learning model.OWSA demonstrated consistent clinical diagnostic performance for OSA. The interpretive machine learning models used in OWSA highlighted the impact of multi-modal data on estimation results. Therefore, these types of models are likely to be more widely accepted and promoted in clinical practice.Keywords: obstructive sleep apnea, photoplethysmography, polysomnography, smartwatch

Eosinophils and platelet are involved in the development of COPD, which may predict adverse events. The objective of this study was to determine the effect of the eosinophil to platelet ratio (EPR) in predicting adverse events in patients with AECOPD who visited the emergency department.Patients and Methods: The records of patients with AECOPD treated at Dalian Municipal Friendship Hospital from January 2018 to December 2020 were retrospectively reviewed. The relationship between the clinical characteristics and EPR, as cut-off value of 0.755, was evaluated.Results: A total of 508 patients with an AECOPD (316 male, 192 female) were included. An optimal AUC cutoff of 0.755 for the EPR segregated the patients into 2 groups with significantly different mortality (25.3% vs 5.5%, P < 0.001). The same mortality risk with lower EPR was observed among the patients with emergency room attendance (35.6% vs 11.1%, P < 0.001). A model including EPR < 0.755, exacerbation history, PaO2 < 60mmHg, PaCO2 > 50 mm Hg, hypoalbuminemia and age ≥ 80 was developed to predict death risk and showed good performance.Conclusion: During severe COPD exacerbation, an EPR < 0.755 preceding therapy can predict worse outcomes in patients with an AECOPD.Keywords: eosinophil, COPD, eosinophil to platelet ratio, emergency department

The SLE/AAV overlap syndrome mainly affects kidney, blood count, nervous system and lung. However, few previous cases reported nasal septal and palatal perforation in this disorder.Case Presentation: We presented a case of a 16-year-old female with a 6-month history of SLE, developed perforation of the nasal septum and palate. She was diagnosed with SLE due to facial malar rash, oral ulcer, increased erythrocyte sedimentation rate (ESR), low complement levels, and positive anti-Smith antibody. Approximately 6 months later, she had a perforation of the nasal septum and palate with positive anti-proteinase 3 antibody (anti-PR3-ANCA). A nasal endoscopic biopsy revealed an inflammatory polyp with chronic suppurative inflammation and inflammatory granulomatous hyperplasia. In this case, the clinical, biological, radiological, and histological findings substantiated the diagnosis of AAV. Infections, drug abuse, malignancies, IgG4-related disease (IgG4-RD) and trauma were excluded. So we diagnosed her with SLE/AAV overlap syndrome.Conclusion: When a patient’s symptoms cannot be explained by one disease, we need to consider the overlapping of two diseases, especially in patients with autoimmune diseases.Keywords: perforation of palate, systemic lupus erythematosus, ANCA-associated vasculitis, SLE/AAV overlap syndrome

This study explores whether CHF checklist management is more useful than usual care in reducing adverse health outcomes in the medium- and long-term among CHF patients.Methods: In our prospective study, 132 patients with CHF were randomly assigned to CHF management group and usual care group by random number method. Patients in CHF management group were conducted through CHF checklist by cardiologists and general practitioner. Patients assigned to usual care were treated by non-stationary medical group without checklist. All groups were followed up for 18 months.Results: There was no significant difference in overall mortality rate between management group and control group during 18 months (12.3% [8/65] vs. 11.7% [7/60], P = 0. 912]). The re-hospitalization rate of heart failure in management group (18.5% [12/65]) was significantly lower than that in usual care group (38.3% [23/60]) after 18 months of follow-up (P = 0.013). Median NT-proBNP level (632.3 ng/l vs. 1678 ng/l, p = 0.004) was lower in management group than that in usual care group. Cardiac ultrasonography was performed at 18 months between the management and usual care group. LVEDD (55.88± 7.11 mm vs. 60.92± 8.06 mm) and LVESD (43.25± 8.42mm vs. 48.41± 9.02mm) were decreased (P< 0.01). LVEF was increased (45.36± 10.64% vs. 39.96 ± 10.15%, P< 0.01). The utilization rate of ACEI/ARB/ARNI, β-blocker were high in management group.Conclusion: CHF checklist management by cardiologists and general practitioners can significantly reduce the re-hospitalization and improve cardiac function. CHF management through heart failure checklist may improve prognosis in patients with CHF in the medium- and long-term.Keywords: chronic heart failure, heart failure management, heart failure checklist, prognosis, re-hospitalization rate, CHF

According to reports, TNFSF13 and HSPG2 are associated with various fibrotic diseases. The aim of this study is to investigate how TNFSF13 and HSPG2 affect the formation of hypertrophic scar (HS) and the mechanism by which exosomes regulate HS.Methods: Immunohistochemistry, qRT-PCR, Western blot, and immunofluorescence were performed to measure TNFSF13 expression in HS skin tissues and hypertrophic scar fibroblast (HSF). HSF were treated with recombinant TNFSF13 protein and TNFSF13 siRNAs to probe the effect of TNFSF13 on the activity of HSF. The CCK-8, EdU, Transwell, and Western blot were used to investigate the role of TNFSF13 in viability, proliferation and inflammation. The influence of MSC-exo on the proliferation and function of HSF was determined by scratch and Western blot.Results: TNFSF13 was dramatically up-regulated in HS skin tissues and HSF. Recombinant TNFSF13 protein increased cell viability, proliferation, migration, fibrosis, inflammation, and the binding between TNFSF13 and HSPG2 of HSF. The opposite results were obtained in TNFSF13 siRNAs transferred HSF. Furthermore, TNFSF13 activated the nuclear factor-κB (NF-κB) signaling pathway. Silencing of HSPG2 and inhibition of NF-κB remarkably eliminated the promoting effects of TNFSF13 on cell viability, proliferation, migration, fibrosis and inflammation of HSF. MSC-exo reduced α-SMA and COL1A1 inhibited the proliferation and migration of HSF by inhibiting TNFSF13 and HSPG2.Conclusion: TNFSF13 activates NF-κB signaling pathway by interacting with HSPG2, which regulates the proliferation, migration, fibrosis and inflammatory response of HSF. Through the above mechanisms, knocking out TNFSF13 can inhibit the proliferation, migration, fibrosis and inflammatory response of HSF, whereas MSC-exo could reverse this process. These results suggest that MSC-exo alleviates HS by inhibiting the fibroblasts via TNFSF-13/HSPG2 signaling pathway.Keywords: TNFSF13, HSPG2, hypertrophic scar(HS), MSC-exo, fibroblasts

To enhance the efficacy of targeted agents, we demonstrate a novel self-assemble amphiphilic molecule based on erlotinib as an effective nanodrug for anti-cancer treatment.Methods: An amphiphilic molecule composed of hydrophobic erlotinib and hydrophilic biotin block was synthesized and characterized by nuclear magnetic resonance (NMR) as well as high-resolution mass spectrometry (HRMS). Then, nanoassemblies of the amphiphilic molecules are formulated by using nanoprecipitation method. Subsequently, the size, morphology, cell uptake, the anticancer activity and in vivo distribution of the newly constructed erlotinib nanodrug were systematically assessed by some methods, including transmission electron microscopy (TEM), dynamic light-scattering (DLS), flow cytometry, in vivo imaging system etc.Results: We developed a novel nanoformulation of erlotinib, which possesses a high drug loading of 45%. With the features of well-defined structure and small size, the obtained nanodrug could be effectively accumulated in tumor sites and rapidly internalized by cancer cells. Finally, the erlotinib-based nanoformulation showed considerably better anticancer activity compared to free erlotinib both in vitro and in vivo. Moreover, the nanodrug displayed great tolerability.Conclusion: Combining the advantageous features of both nanotechnology and self-assemble, this novel erlotinib nanomedicine constitutes a promising therapeutic candidate for cancer treatment. This study also underlines the potential use of amphiphilic molecule for improving drug efficacy as well as reducing drug toxicity, which could become a general strategy for the preparation of nanodrugs of active agents.Keywords: erlotinib, amphiphilic molecule, self-assembling, drug self-delivery system, non-small cell lung cancer

A total of 1634 GM patients and 186 healthy women during the same period were included and randomly divided into the modeling and validation groups in a 7:3 ratio. To identify the independent risk factors of GM, univariate and multivariate logistic analyses were conducted and used to develop a nomogram. The prediction model was internally and externally validated using the Bootstrap technique and validation cohort. The receiver operating characteristic (ROC) curve and calibration curve were used to evaluate the discrimination and calibration of the prediction model. Decision curve analysis (DCA) and clinical impact curve (CIC) were used to evaluate the clinical significance of the model.Results: The average age of GM patients was 33.14 years (mainly 20– 40). The incidence was high within five years from delivery and mainly occurred in the unilateral breast. The majority of the patients exhibited local skin alterations, while some also presented with systemic symptoms. On multivariate logistic analysis, age, high prolactin level, sex hormone intake, breast trauma, nipple discharge or invagination, and depression were independent risk factors for GM. The mean area under the curve (AUC) in the modeling and validation groups were 0.899 and 0.889. The internal and external validation demonstrated the model’s predictive ability and clinical value.Conclusion: Lactation-related factors are the main risk factors of GM, leading to milk stasis or increased ductal secretion. Meanwhile, hormone disorders could affect the secretion and expansion of mammary ducts. All these factors can obstruct or injure the duct, inducing inflammatory reactions and immune responses. Additionally, blunt trauma, depressed mood, and diet preference can accelerate the process. The nomogram can effectively predict the risk of GM.Keywords: granulomatous mastitis, risk factors, case-control study, nomogram, prediction model

Therefore, a RA-loaded PEGylated liposome drug delivery system was devised in this study.Methods: Hydrogenated soybean phospholipids (HSPC), 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-Polyethyleneglycol-2000 (sodium salt) (DSPE-PEG2k), cholesterol (CHO), and RA were utilised to prepare a RA-loaded liposome (LRA) drug delivery system via the thin film hydration technique., The drug loading content was confirmed by high performance liquid chromatography. Dynamic light scattering was employed to evaluate the drug’s particle size and stability. Methyl tetrazolium, colony formation, and Western blot (WB) were used in vitro to elucidate the inhibitory effect and mechanism of LRA on prostate cancer cells. Finally, xenograft model was used to confirm the tumor-inhibiting efficacy, clarify the mechanism, and determine the biosafety in mice.Results: LRA has stable physicochemical properties and a diameter of 173.5 15.3 nm. LRA inhibited the growth of prostate cancer cells in a dose- and time-dependent manner. LRA can substantially reduce the expression of AR and HMGB1, induce apoptosis, regulate the expression of cell cycle-related proteins in vitro and in vivo. The results of the biosafety tests demonstrated that LRA effectively reduced the adverse effects of RA.Conclusion: As a drug delivery system, LRA could effectively and safely inhibit the progression of prostate cancer.Graphical Abstract: Keywords: prostate cancer, liposome, Raddeanin A, HMGB1, AR

The objective of this study is to explore the predisposing factors for GLM.Patients and methods: This case-control study was conducted from 2018 to 2021 at Beijing Hospital of Traditional Chinese Medicine, Capital Medical University. Patients with GLM (cases) were matched with healthy examinees (controls) in a 1:1 ratio according to gender and living area. We analyzed their demographic features and investigated 75 factors that may be relevant to GLM using a standard questionnaire. Univariate and multivariable binary conditional logistic regression analyses were used to compare the differences between the two groups and evaluate the predisposing factors that may induce GLM.Results: There were 594 female GLM patients and 594 matched controls included in the study. The average age of the cases was 32.78 years (mainly 20 to 40). The incidence was high within five years after childbirth, and lesions were mainly in the unilateral breast. Univariate and multivariable conditional logistic regression analyses obtained six relevant factors and six high-risk factors. The six relevant factors included age, marriage, emotional abnormality, high prolactin, psychiatric drug intake, and sex hormone intake. Additionally, the independent high-risk factors for GLM included gestation, nipple invagination, blunt trauma, non-iatrogenic massage, lactation disorder, and nipple discharge (odds ratio (OR)=17.378, 8.518, 4.887, 3.116, 2.522, 1.685, P< 0.05). Menopause was an independent protective factor (OR=0.249, P< 0.05).Conclusion: The factors that increase milk and secretion production in the mammary duct are the main risk factors of GLM, especially when the nipples are invaginated. These factors can obstruct the duct and induce inflammation. Additionally, hormonal disorders, extrinsic trauma, and emotional abnormalities can accelerate the occurrence of GLM.Keywords: granulomatous lobular mastitis, GLM, predisposing factor, risk factor, case-control study, etiology

It may cause serious dysfunction, resulting in psychological and physiological burdens on the patients. Currently, mesenchymal stem cells-derived exosomes (MSC-Exo) displayed a promising therapeutic effect on wound repair and scar attenuation. But the regulatory mechanisms are opinions vary. In view of inflammation has long been proven as the initial factor of wound healing and scarring, and the unique immunomodulation mechanism of MSC-Exo, the utilization of MSC-Exo may be promising therapeutic for pathological scars. However, different immune cells function differently during wound repair and scar formation. The immunoregulatory mechanism of MSC-Exo would differ among different immune cells and molecules. Herein, this review gave a comprehensive summary of MSC-Exo immunomodulating different immune cells in wound healing and scar formation to provide basic theoretical references and therapeutic exploration of inflammatory wound healing and pathological scars.Keywords: exosomes, inflammation, immune cells, immunoregulation, scars

The rapid development of computing applications demands novel low-energy consumption devices for information processing. Among various candidates, magnetoelectric heterostructures hold promise for meeting the required voltage and power goals. Here, a route to low-voltage control of magnetism in 30 nm Fe0.5Rh0.5/100 nm 0.68PbMg1/3Nb2/3O3-0.32PbTiO3 (PMN-PT) heterostructures is demonstrated wherein the magnetoelectric coupling is achieved via strain-induced changes in the Fe0.5Rh0.5 mediated by voltages applied to the PMN-PT. We describe approaches to achieve high-quality, epitaxial growth of Fe0.5Rh0.5 on the PMN-PT films and, a methodology to probe and quantify magnetoelectric coupling in small thin-film devices via studies of the anomalous Hall effect. By comparing the spin-flop field change induced by temperature and external voltage, the magnetoelectric coupling coefficient is estimated to reach ≈7 × 10−8 s m−1 at 325 K while applying a −0.75 V bias.

Cognitive performance in children is predictive of academic and social outcomes; therefore, understanding neurobiological mechanisms underlying individual differences in cognition during development may be important for improving quality of life. The belief that a single, psychological construct underlies many cognitive processes is pervasive throughout society. However, it is unclear if there is a consistent neural substrate underlying many cognitive processes. Here, we show that a distributed configuration of cortical surface area and apparent thickness, when controlling for global imaging measures, is differentially associated with cognitive performance on different types of tasks in a large sample (N = 10 145) of 9-11-year-old children from the Adolescent Brain and Cognitive DevelopmentSM (ABCD) study. The minimal overlap in these regionalization patterns of association has implications for competing theories about developing intellectual functions. Surprisingly, not controlling for sociodemographic factors increased the similarity between these regionalization patterns. This highlights the importance of understanding the shared variance between sociodemographic factors, cognition and brain structure, particularly with a population-based sample such as ABCD.

However, a reasonable and concise score is needed to evaluate TACE and TACE combined with systemic therapy in HCC treatment.Methods: The HCC patients were grouped into two groups: training group (n = 778) (treated with TACE) and verification group (n = 333). The predictive value of baseline variables on overall survival was analyzed using COX model, and easy-to-use ALR (AST and Lym-R) scores. The best cut-off value of AST and Lym-R were determined using X-Tile software based on total survival time (OS) and further verified via a restricted three-spline method. Meanwhile, the score was further verified using two independent valid sets: TACE combined with targeted therapy and TACE with targeted combined immunotherapy.Results: In multivariate analysis, baseline serum AST> 57.1 (p < 0.001) and Lym-R≤ 21.7 (p < 0.001) were identified as independent prognostic factors. The OS of patients in the TACE pooled cohort with 0, 1, and 2 scores were 28.1 (95% CI 24– 33.8) months, 15 (95% CI 12.4– 18.6) months, and 7.4 (95% CI 5.7– 9.1) months, respectively. The time-varying ROC curve based on ALR showed that the AUC values for predicting 1, -2-and 3-year OS were 0.698, 0.718, and 0.636, respectively. These results are confirmed in two independent valid sets of TACE combined with targeted therapy and TACE with targeted combined immunotherapy. And we established a nomogram after COX regression to predict the 1 -, 2- and 3-year survival time.Conclusion: Our study confirmed that ALR score can predict the prognosis of HCC treated with TACE or TACE combined with systemic therapy.Keywords: TACE, immunotherapy, targeted therapy, nomogram

H. pylori infection can also cause a variety of stomach diseases, which can only be treated with a combination of antibiotics. Combinations of antibiotics can cure H. pylori infection, but it is easy to relapse and develop drug resistance. Therefore, a vaccine is a promising strategy for prevention and therapy for the infection of H. pylori. After decades of research and development, there has been no appearance of any H. pylori vaccine reaching the market, unfortunately. This review summarizes the aspects of candidate antigens, immunoadjuvants, and delivery systems in the long journey of H. pylori vaccine research, and also introduces some clinical trials that have displayed encouraging or depressing results. Possible reasons for the inability of an H. pylori vaccine to be available over the counter are cautiously discussed and some propositions for the future of H. pylori vaccines are outlined.Graphical Abstract: Keywords: Helicobacter pylori vaccines, antigen, adjuvant, delivery system, clinical trials
