Objective To investigate the clinical value of 3.0 T functional magnetic resonance imaging in evaluating postoperative recurrence and treatment efficacy of glioma. Methods A retrospective analysis was conducted on the general clinical data of 67 patients who underwent glioma surgery at the Second Affiliated Hospital of Xingtai Medical University. All patients received chemotherapy for more than one month post-surgery. Recurrence of glioma was diagnosed based on secondary surgery or pathological biopsy results as the gold standard. From 3 to 6 months post-surgery, computerized tomography was used to measure cerebral blood volume (CBV), three-dimensional arterial spin labeling was used to measure cerebral blood flow (CBF) and relative CBF (rCBF), and diffusion-weighted imaging with and without contrast enhancement was used to measure apparent diffusion coefficient (ADC). Data were analyzed using SPSS 26.0 statistical software, and the t test or χ² test was used for inter-group comparisons based on data type. The receiver operating characteristic (ROC) curve was applied to evaluate the value of CBV, rCBF, and ADC in assessing postoperative recurrence and treatment efficacy of glioma. Results Patients with high-grade gliomas showed significantly higher CBV and rCBF and significantly lower ADC compared to those with low-grade gliomas (P < 0.05). The area under the ROC curve (AUC) of CBV, rCBF, and ADC in combination for grading glioma was 0.960, which was higher than those of individual indicators (0.790, 0.955, and 0.795, P < 0.05). The recurrence group had significantly higher CBV and rCBF and lower ADC compared to the non-recurrence group (P < 0.05). The AUC of CBV, rCBF, and ADC in combination for predicting postoperative glioma recurrence was 0.965, which was significantly higher than those of individual indicators (0.729, 0.929, and 0.941, P < 0.05). CBV and rCBF were lower and ADC was higher in the effective treatment group than in the ineffective treatment group (P < 0.05). The AUC of CBV, rCBF, and ADC in combination for evaluating glioma treatment efficacy was 0.985, which was higher than those of individual indicators (0.842, 0.898, and 0.961, P < 0.05). Conclusion The CBV, rCBF, and ADC in combination has shown high diagnostic accuracy and predictive efficacy in the evaluation of postoperative recurrence and treatment efficacy of glioma, which has important clinical application value.

BACKGROUND:Tyrosine kinase inhibitors,as well as other types of small-molecule cancer drugs,can cause severe cardiotoxicity. OBJECTIVE:To perform a heart safety re-evaluation by observing the effects of antitumor drugs on isolated heart electrocardiograph,cardiac action potential and associated ion channels and cytotoxicity. METHODS:Extracorporeal cardiac perfusion was given to the isolated rabbit heart using Langendorff perfusion:Sunitinib(0.3,3,10 μmol/L),Crizotinib(0.3,1,3 μmol/L),and Doxorubicin(1,30 μmol/L)were perfused sequentially for 120 minutes to record electrocardiograph and left ventricular pressure.A blank control group was set for comparison.Manual patch clamp was used to record the effects of Crizotinib,Sunitinib,Doxorubicin on hERG,Cav1.2,Nav1.5 channel currents and action potential in human induced pluripotent stem cell derived cardiomyocytes.Adenosine triphosphate level in human induced pluripotent stem cell derived cardiomyocytes was detected by CellTiter-Glo luminescent cell viability assay. RESULTS AND CONCLUSION:Isolated rabbit heart using Langendorff perfusion:Compared with the blank ontrol group,Sunitinib and Crizotinib at≥3 μmol/L decreased heart rate(P<0.01)and prolonged QT/QTc interval(P<0.01),and reduced left ventricular pressure to different extents.Manual patch clamp recording:Compared with the blank control group,Sunitinib and Crizotinib at 3 μmol/L inhibited the activities of hERG,Nav1.5 and Cav1.2 channels and significantly prolonged the duration of action potential(P<0.01).According to the analysis of the test article,the difference between the labeled concentration and the measured concentration of the recovered solution was not significant.Cell viability assays:Compared with the blank control group,adenosine triphosphate content in human induced pluripotent stem cell derived cardiomyocytes significantly decreased after treatment with Sunitinib(IC50=4.64 μmol/L),Doxorubicin(IC50=4.21 μmol/L)and Crizotinib(IC50=2.87 μmol/L),indicating that cell viability significantly decreased(P<0.01).To conclude,this study successfully established an early cardiac safety evaluation method for antitumor drugs,which provides good support and help for the subsequent development of antitumor drugs.

In order to explore the medical and social problems related to postoperative lymphedema in breast cancer patients, improve the compliance of rehabilitation treatment and help patients return to society. The self-designed questionnaire was used to investigate 76 patients who met the criteria of lymphedema after breast cancer and refused or failed to adhere to rehabilitation threapy. According to the relevant measurement scale theory and method, the computer-aided software was used to analyze the data to find out the problem and analyze the cause. The prominent problems of poor compliance in patients with breast cancer after operation were successively: subjective factors, objective factors, family social and ethical factors, multidisciplinary factors, hospital management and policy issues. For the above ethical problems, we should adopt positive coping strategies to increase the compliance of patients and improve their quality of life.

Objective To study the differences in the blood cell analysis of male officers and soldiers be-tween in the high altitude area station and low altitude area station in summer.Methods A total of 239 male officers and soldiers in the high altitude area(Amdo Xizang,average altitude 4 800 m)and 336 male officers and soldiers in the low altitude area(Nanjing,Jiangsu,average altitude 30 m)from July 18 to 24,2022 were selected as the study subjects and the differences in blood cell analysis parameters of male officers and soldiers stationed between at high altitude and low altitude areas were retrospectively analyzed.Results The eosino-phils percentage(EDS％),eosinophils count(EOS)in the high altitude group were significantly lower than thosein the low altitude group(P＜0.05),and the basophillic granulocyte percentage(BASO％),basophillic granulo-cyte count(BASO)and monocyte percentage(MONO％)were significantly higher than those in the low alti-tude group,and the differences were statistically significant(P＜0.05),but which in the both groups were in the normal reference ranges.The red blood cell count(RBC)hemoglobin(Hb)and hematocrit(HCT)in the high altitude group were significantly higher than those in the low altitude group(P＜0.05),moreover Hb and HCT in the high altitude group were in the upper limit of the medical reference range.The mean corpus-cular volume(MCV),mean corpuscular hemoglobin(MCH),mean corpuscular hemoglobin concentration(MCHC)and red blood cell distribution width-standard diviation(RDW-SD)in the high altitude group were lower than those in the low-altitude group(P＜0.05),but the both groups were in the normal reference ran-ges;there was no statistically significant difference in the erythrocyte distribution width coefficient of variation(RDW-CV)between the two groups(P＞0.05).The platelet(PLT)and thrombocytocrit(PCT)in the high altitude group were higher than those in the low altitude group,the platelet distribution width(PDW),mean platelet volume(MPV)and platelet large cell ratio(P-LCR)were lower than those in the low altitude group,and the differences were statistically significant(P＜0.05);PDW in the low-altitude group was at the upper limit of the medical reference range,and the other platelet-related indexes were in the normal range.Conclusion There are obvious differences in the blood cell analysis indicators of male officers and soldiers be-tween the high altitude area and low altitude area.

Objective:To investigate whether short chain fatty acid(SCFAs) intervention has an antidepressant effect by improving gut microbiota dysregulation and regulating the TLR4/MyD88/NF-κB inflammatory pathway in depression model mice.Methods:Totally 60 SPF grade male C57BL/6 J mice aged 6-8 weeks were randomly divided into three groups: control group, depression model group, and SCFAs group, with 20 mice in each group.The mice in depression model group and SCFAs group were given the chronic unpredictable mild stress (CUMS) stimulations for 8 weeks to establish the depression model.From the 6th week, SCFAs group mice were given a mixed solution of short chain fatty acid salts for drinking, until modeling was completed, meanwhile mice in the model group were given 0.78% NaCl solution for drinking.The depression-like behavior was assessed using the sucrose preference test (SPT) and forced swimming test (FST) following modeling, and the open field test (OFT) was employed to evaluate the anxiety-like behavior of mice.16S rRNA gene sequence was used to analyze the gut microbiota of mice.The activation of astrocytes and TLR4/MyD88/NF-κB inflammatory pathway in hippocampus was determined by immunofluorescence staining and Western blot.SPSS 26.0 was used for statistical analysis, one-way ANOVA was used for comparison among the three groups, and LSD- t test was used for further pairwise comparisons. Results:There were statistically significant differences in the sugar water preference rate, the immobility time in FST, and the percentage of activity time in OFT among the three groups ( F=10.554, 10.912, 12.599, all P<0.05).The the sugar water preference rate and the percentage of activity time in OFT of the depression model group were both lower than those of the control group (both P<0.05), and the immobility time in FST was higher than that of the control group ( P<0.05).The sugar water preference rate in SCFAs group((84.7±3.5)%, (75.3±6.0)%)and the percentage of activity time in OFT((7.4±1.4)%, (3.2±0.9)%) were both higher than those in the depression model group(both P<0.05 ), while the immobility time in FST was shorter than that in the depression model group((110.5±21.5) s, (148.0±20.1) s, P<0.05).There was a statistical difference in the β diversity of gut microbiota among three groups ( P=0.001).At the family level, compared with the depression model group, the relative abundance of Rikenellaceaee and Bacteroidaceae increased in the SCFAs group, while the relative abundance of Clostridia_UCG-014 decreased.At the genus level, the relative abundance of Clostridia_UCG-014 and Prevotella decreased, while the relative abundance of Alistipes increased (all P<0.05).The immunofluorescence results showed that there was a statistically significant difference in GFAP expression levels among the three groups of mice ( F=16.565, P=0.004).The GFAP expression in the depression model group was higher than that in the control group and SCFAs group (both P<0.05).The Western blot results showed that there were statistically significant differences in the expression levels of TLR4, MYD88, and NF-κB ptoteins in the hippocampal tissue of the three groups ( F=70.59, 174.39, 14.40, all P<0.05).The protein levels of TLR4, MyD88, and NF-κB in the depression model group were all higher than those in the control group and SCFAs group (all P<0.05). Conclusion:SCFAs can ameliorate the depressive-like behavior in depression model mice and reduce the activation of astrocytes in the hippocampus, which may be associated with the improvement of dysregulated gut microbiota and down-regulation of the TLR4/MyD88/NF-κB pathway protein.

Objective:To investigate the changes in interaction proteome of NUS1 mutant R290C and their relations with pathogenicity of Lennox Gastaut syndrome (LGS). Methods:The wild-type and mutant NUS1(R290C) plasmids were constructed and transfected into human embryonic kidney HEK293T cells; 48 h after that, NUS1 protein expression in HEK293T cells was detected by Western blotting. Co-immunoprecipitation, silver nitrate staining, and proteomic analysis were used to analyze the proteins interacted with wild-type or mutant NUS1 and identify the differential interacting proteins. Enrichment analyses of Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) were performed to annotate the molecular function and signaling pathways involved in the differential proteins. DisGeNet database was used to analyze the association between differential proteins and human diseases. Protein-protein interaction (PPI) was used to analyze the interaction network of NUS1 with protein folding regulatory proteins (RTN4 and DHDDS) and developmental epileptic encephalopathy related proteins.Results:(1) There was no significant difference in NUS1 protein expression between the wild-type and mutant NUS1 transfected HEK293T cells ( t=0.536, P=0.620). (2) Compared with that with wild-type NUS1 plasmid, number of proteins interacting with mutant NUS1 plasmid was significantly reduced in the transfected cells; 310 differential interacting proteins were screened in the mutant NUS1. (3) GO and KEGG enrichment analyses showed that the differential proteins were mainly involved in protein folding reaction and translation regulation. (4) DisGeNet association analysis showed that the two most relevant proteins in the differential interacting proteins were associated with frontotemporal dementia and developmental epileptic encephalopathy. (5) PPI analysis showed that NUS1 may be involved in occurrence of neurological diseases such as LGS by affecting protein folding signaling pathways. Conclusion:NUS1 mutant R290C alters its interacting protein lineage and mediates the development of LGS and other neurological diseases probably by regulating protein folding-related signaling.

A colon-specific drug delivery system has great potential for the oral administration of colorectal cancer. However, the uncontrollable in vivo fate of liposomes makes their effectiveness for colonic location, and intratumoral accumulation remains unsatisfactory. Here, an oral colon-specific drug delivery system (CBS-CS@Lipo/Oxp/MTZ) was constructed by covalently conjugating Clostridium butyricum spores (CBS) with drugs loaded chitosan (CS)-coated liposomes, where the model chemotherapy drug oxaliplatin (Oxp) and anti-anaerobic bacteria agent metronidazole (MTZ) were loaded. Following oral administration, CBS germinated into Clostridium butyricum (CB) and colonized in the colon. Combined with colonic specifically β-glucosidase responsive degrading of CS, dual colon-specific release of liposomes was achieved. And the accumulation of liposomes at the CRC site furtherly increased by 2.68-fold. Simultaneously, the released liposomes penetrated deep tumor tissue via the permeation enhancement effect of CS to kill localized intratumoral bacteria. Collaborating with blocking the translocation of intestinal pathogenic bacteria from lumen to tumor with the gut microbiota modulation of CB, the intratumoral pathogenic bacteria were eliminated fundamentally, blocking their recruitment to immunosuppressive cells. Furtherly, synchronized with lipopolysaccharide (LPS) released from MTZ-induced dead Fusobacterium nucleatum and the tumor-associated antigens produced by Oxp-caused immunogenic dead cells, they jointly enhanced tumor infiltration of CD8⁺ T cells and reactivated robust antitumor immunity.

Activating humoral and cellular immunity in lymph nodes (LNs) of nanoparticle-based vaccines is critical to controlling tumors. However, how the physical properties of nanovaccine carriers orchestrate antigen capture, lymphatic delivery, antigen presentation and immune response in LNs is largely unclear. Here, we manufactured gold nanoparticles (AuNPs) with the same size but different shapes (cages, rods, and stars), and loaded tumor antigen as nanovaccines to explore their disparate characters on above four areas. Results revealed that star-shaped AuNPs captured and retained more repetitive antigen epitopes. On lymphatic delivery, both rods and star-shaped nanovaccines mainly drain into the LN follicles region while cage-shaped showed stronger paracortex retention. A surprising finding is that the star-shaped nanovaccines elicited potent humoral immunity, which is mediated by CD4⁺ T helper cell and follicle B cell cooperation significantly preventing tumor growth in the prophylactic study. Interestingly, cage-shaped nanovaccines preferentially presented peptide-MHC I complexes to evoke robust CD8⁺ T cell immunity and showed the strongest therapeutic efficacy when combined with the PD-1 checkpoint inhibitor in established tumor study. These results highlight the importance of nanoparticle shape on antigen delivery and presentation for immune response in LNs, and our findings support the notion that different design strategies are required for prophylactic and therapeutic vaccines.
