OBJECTIVE: To observe the effect of electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) on hippocampal neuronal ferritinophagy mediated by the nuclear receptor coactivator 4 (NCOA4)/ferritin heavy chain 1 (FTH1) signaling pathway in vascular dementia (VD) rats, and to explore the potential mechanisms of electroacupuncture for VD. METHODS: A total of 60 male rats of SPF grade were randomly divided into a blank group (12 rats), a sham surgery group (12 rats) and a modeling group (36 rats). In the modeling group, the modified 4-vessel occlusion method was used to establish the VD model. The 24 successfully modeled rats were randomly divided into a model group and an electroacupuncture group, with 12 rats in each group. In the electroacupuncture group, electroacupuncture was applied at left and right "Sishencong" (EX-HN1), and bilateral "Fengchi" (GB20), with continuous wave, in frequency of 2 Hz and current intensity of 1 mA, 30 min a time, once daily for 21 consecutive days. The learning and memory abilities were assessed using the Morris water maze test before modeling, after modeling and after intervention, as well as the novel object recognition test after intervention. After intervention, the neuronal morphology in the hippocampus was observed by Nissl staining; the iron deposition was observed by Prussian blue staining; the reactive oxygen species (ROS) level was detected by dihydroethidium (DHE) fluorescence staining; the levels of iron, malondialdehyde (MDA) and superoxide dismutase (SOD) in the hippocampal tissue were measured by the colorimetric assay, TBA method, and WST-1 method, respectively; the positive expression of NCOA4, FTH1 and glutathione peroxidase 4 (GPX4) was detected by immunohistochemistry; the protein expression of NCOA4, FTH1, GPX4, and the ratio of microtubule-associated protein 1 light chain 3B (LC3B) Ⅱ/Ⅰ in the hippocampus were detected by Western blot. RESULTS: Compared with the sham surgery group, in the model group, the escape latency was prolonged, and the number of platform crossings reduced (P<0.01), the recognition index (RI) was decreased (P<0.01); the hippocampal neurons displayed a blurred laminar structure, disorganized cellular arrangement, and the number of Nissl bodies was decreased (P<0.01); the percentage of iron deposition area in the hippocampus was increased (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were increased (P<0.01), the SOD level, and the protein expression of FTH1 and GPX4 were decreased (P<0.01). Compared with the model group, in the electroacupuncture group, the escape latency was shortened and the number of platform crossings was increased (P<0.01), the RI was increased (P<0.01); the hippocampal neurons exhibited more regular morphology, better-organized cellular structure, and the number of Nissl bodies was increased (P<0.05); the percentage of iron deposition area in the hippocampus reduced (P<0.01); in the hippocampus, the levels of ROS, iron, MDA, and the protein expression of NCOA4, as well as the LC3B Ⅱ/Ⅰ ratio were decreased (P<0.01, P<0.05), the SOD level, and the protein expression of FTH1 and GPX4 were increased (P<0.01). CONCLUSION Electroacupuncture at "Sishencong" (EX-HN1) and "Fengchi" (GB20) can improve learning and memory abilities in VD rats, and its mechanism may be associated with the regulation of the hippocampal NCOA4/FTH1 signaling pathway, inhibition of ferritinophagy, and alleviation of oxidative stress damage.

OBJECTIVE: To investigate the predictive value of endothelial activation and stress index (EASIX) for the prognosis of patients with mantle cell lymphoma (MCL). METHODS: A retrospective analysis was conducted to assess prognosis and compare the clinical features of patients diagnosed with MCL who were admitted to the Affiliated Hospital of Xuzhou Medical University from January 2010 to June 2023, had therapeutic indications and received standard treatment. RESULTS: A total of 66 patients were included and divided into high EASIX group and low EASIX group, according to a cutoff value of 0.97 determined by the receiver operating characteristic (ROC) curve. Multivariate Cox regression analysis showed that prealbumin <0.2 g/L, high EASIX, and ECOG PS score ≥2 were independent risk factors influencing overall survival (OS) in MCL patients. The median OS of patients in the high and low EASIX group was 13.0 and 37.5 months, and the median progression-free survival was 8.8 and 26.0 months, respectively. The proportions of patients with ECOG PS score ≥2 and prealbumin <0.2 g/L at onset significantly increased in the high EASIX group compared to those in the low EASIX group. CONCLUSION At the time of initial diagnosis, EASIX can serve as an independent prognostic indicator impacting OS in patients with MCL. Furthermore, patients in the high EASIX group experience a poorer prognosis and shorter survival duration compared with those in the low EASIX group.

OBJECTIVE: To investigate the predictive role of the modified Endothelial Activation and Stress Index (mEASIX) in the efficacy of chimeric antigen receptor T-cell (CAR-T) therapy and cytokine release syndrome (CRS). METHODS: The clinical data of 70 relapsed and refractory (R/R) B-cell tumor patients who were treated with CAR-T therapy from September 1, 2018 to February 28, 2023 in the Department of Hematology, Affiliated Hospital of Xuzhou Medical University, were retrospectively analyzed. The value of log-2 mEASIX before conditioning (-7 d) was calculated, and the patients were divided into a low-mEASIX group (42 patients) and a high-mEASIX group (28 patients) based on the cut-off value of 5.443 determined by the receiver operating characteristic (ROC) curve. Eventually, the predictive role of mEASIX before conditioning on the efficacy of CAR-T cell therapy and CRS was analyzed. RESULTS: The high-mEASIX group exhibited significantly worse median overall survival (OS) and median progression-free survival (PFS) in comparison to the low mEASIX group (OS: 3.2 months vs not reached, P < 0.01; PFS: 1.3 months vs 6.0 months, P =0.009). The incidence of grade ≥2 CRS in the high-mEASIX group was substantially higher than that in the low-mEASIX group (57.1% vs 19.0%, P =0.007). The degree of remission after CAR-T therapy (P =0.001), whether CRS occurs or not (P =0.041), the lactate dehydrogenase (LDH) level before conditioning (P =0.046), and the mEASIX score before conditioning (P =0.047) were independent influencing factors for the OS of patients receiving CAR-T cell therapy. CONCLUSION The mEASIX score before conditioning can predict OS and the incidence of grade ≥2 CRS in patients with relapsed and refractory B-cell tumors who receive CAR-T cell therapy.

OBJECTIVE: The present study evaluated the effects of deep acupuncture at Weizhong acupoint (BL40) on bladder function and brain activity in a rat model of overactive bladder (OAB), and investigated the possible mechanisms around the acupuncture area that initiate the effects of acupuncture. METHODS: Adult female Sprague-Dawley rats were randomly divided into six groups, comprising a control group, model group, group treated with deep acupuncture at BL40, group treated with shallow acupuncture at BL40, group treated with acupuncture at non-acupoint next to BL40, and group treated with acupuncture at Xuanzhong (GB39). Urodynamic evaluation was used to observe the urination, and functional magnetic resonance imaging was used to observe the brain activation. The mechanism of acupuncture at BL40 in regulating bladder function was explored by toluidine blue staining and enzyme-linked immunosorbent assay, and the mechanism was verified by stabilizing mast cells (MCs) or blocking tibial nerve. RESULTS: Deep acupuncture at BL40 significantly increased the intercontraction interval in OAB rats and enhanced the mean amplitude of low frequency fluctuation of primary motor cortex (M1), periaquaductal gray matter (PAG), and pontine micturition center (PMC). It also increased the zero-lag functional connectivity between M1 and PAG and between PAG and PMC. Shallow acupuncture at BL40 and acupuncture at non-acupoint or GB39 had no effect on these indexes. Further studies suggested that deep acupuncture at BL40 increased the number and degranulation rate of MCs as well as the contents of 5-hydroxytryptamine, substance P, and histamine in the tissues around BL40. Blocking the tibial nerve by lidocaine injection or inhibiting MC degranulation by sodium cromoglycate injection obstructed the effects of acupuncture on restoring urinary function and modulating brain activation in OAB rats. CONCLUSION Deep acupuncture at BL40 may be more effective for inhibiting OAB by promoting degranulation of MCs around the acupoint and stimulating tibial nerve, thereby regulating the activation of the brain area that controls the lower urinary tract.

Objective:To investigate the etiology of hand, foot and mouth disease (HFMD) in Mianyang city in 2022, and to analyze the genetic characteristics of coxsackievirus A6.Methods:Pharyngeal swabs were collected from patients with HFMD in Mianyang city in 2022. Real-time fluorescence quantitative PCR was used to detect enteroviruses in the samples. Part of the VP1 gene in enterovirus-positive samples was amplified by nested PCR using enterovirus typing primers to further identify the viral types. The VP1 coding region of all CVA6-positive samples and the whole genome of some samples were amplified and sequenced by PCR. The endemic strain in Mianyang city was analyzed for phylogeny, gene homology, amino acid variation and genetic recombination.Results:A total of 151 pharyngeal swabs were collected, and 104 enterovirus-positive samples were detected by real-time fluorescence quantitative PCR, with an overall detection rate of 68.88% (104/151). The typing results showed that there were 77 cases of CVA6 infection, with a positive rate of 50.99% (77/151). The full-length VP1 genes of 77 CVA6 strains were amplified, sequenced, and successfully spliced, and phylogenetic analysis showed that all 77 strains were of the D3 genotype. There were multiple amino acid variant sites in the prevalent strains in Mianyang city compared with the reference strain. Twenty whole genome sequences were amplified, sequenced, and successfully spliced, and homology analysis showed that the nucleotide homology between the 20 positive sequences ranged from 97.0% to 99.9%. Phylogenetic tree and recombination analysis showed that no recombination occurred in the coding regions of the epidemic strains in this study.Conclusions:The predominant pathogen causing HFMD in Mianyang city in 2022 is CVA6 D3 subtype, which is consistent with the national epidemic in 2022.

Objective To investigate the current status of cleaning and disinfection of endoscopic ultrasound micro-probes in tertiary hospitals in Beijing.Methods 51 tertiary hospitals in Beijing were selected with convenience sam-pling method,and a questionnaire survey was conducted on head nurses in endoscopy centers,the investigation in-cluded pre-treatment,cleaning,disinfection,sterilization,biological testing,disinfection traceability,storage and maintenance of endoscopic ultrasound microprobes.Results Among the 51 tertiary hospitals,33 were first-class hospitals and 18 were second-class hospitals.76.47％(n=39)of hospitals performed bed-side pre-cleaning on ultrasound microprobes after use,bed-side pre-treatment methods for endoscopic ultrasound microprobes mainly included enzyme solution wiping(38.47％,15/39)and ethanol wiping(30.77％,12/39);96.08％(n=49)of hospitals performed manual cleaning for ultrasound microprobes,with"enzyme wash-scrub-dry"as the main method(58.82％,n=30);96.08％(n=49)of hospitals disinfected microprobes after use,with chemical disinfectant im-mersion as the main methods(65.31％,n=32);43.14％(n=22)of hospitals sterilized the microprobes,and the main method of sterilization was immersion in 0.2％-0.35％peroxyacetic acid for 10-15 minutes(77.27％,17/22);41.18％(n=21)of hospitals regularly conducted biological monitoring on microprobes;37.25％(n=19)of hospitals traced the cleaning and disinfection process of microprobes;88.24％(n=45)of hospitals regularly inspec-ted,maintained,and repaired microprobes.Conclusion The pre-treatment,cleaning,disinfection,sterilization,and biological monitoring of endoscopic ultrasound microprobes in 51 tertiary hospitals in Beijing varies significantly,and it is recommended that a relevant expert consensus or guideline be formulated as early as possible,so as to standardize the cleaning and disinfection of endoscopic ultrasound microprobes.

Periodontitis is a common chronic inflammatory disease that causes the periodontal bone destruction and may ultimately result in tooth loss.With the progression of periodontitis,the osteoimmunology microenvironment in periodontitis is damaged and leads to the formation of pathological alveolar bone resorption.CD301b+macrophages are specific to the osteoimmunology microenvironment,and are emerging as vital booster for conducting bone regeneration.However,the key upstream targets of CD301b+macrophages and their potential mechanism in periodontitis remain elusive.In this study,we concentrated on the role of Tim4,a latent upstream regulator of CD301b+macrophages.We first demonstrated that the transcription level of Timd4(gene name of Tim4)in CD301b+macrophages was significantly upregulated compared to CD301b-macrophages via high-throughput RNA sequencing.Moreover,several Tim4-related functions such as apoptotic cell clearance,phagocytosis and engulfment were positively regulated by CD301b+macrophages.The single-cell RNA sequencing analysis subsequently discovered that Cd301b and Timd4 were specifically co-expressed in macrophages.The following flow cytometric analysis indicated that Tim4 positive expression rates in total macrophages shared highly synchronized dynamic changes with the proportions of CD301b+macrophages as periodontitis progressed.Furthermore,the deficiency of Tim4 in mice decreased CD301b+macrophages and eventually magnified alveolar bone resorption in periodontitis.Additionally,Tim4 controlled the p38 MAPK signaling pathway to ultimately mediate CD301b+macrophages phenotype.In a word,Tim4 might regulate CD301b+macrophages through p38 MAPK signaling pathway in periodontitis,which provided new insights into periodontitis immunoregulation as well as help to develop innovative therapeutic targets and treatment strategies for periodontitis.
