Objective:To investigate the relationship between alterations in dynamic functional connectivity (dFC) and spatial navigation abilities in individuals with subjective cognitive decline (SCD) across different Traditional Chinese Medicine (TCM) constitutions.Methods:Seventy-five participants with SCD, comprising 34 individuals with balanced constitutions and 41 individuals with biased constitutions, were recruited from the Affiliated Drum Tower Hospital of Nanjing University Medical School between August 2022 and January 2025. The participants underwent TCM constitution assessment, spatial navigation ability testing, and neuropsychological scale evaluation. Additionally, each participant was assessed using 3.0 T resting-state functional magnetic resonance imaging (rs-fMRI) and high-resolution T1-weighted imaging scans. Based on prior research, 20 spatial navigation-related regions of interest (ROIs) were defined. Afterwards, rs-fMRI time series were segmented using a sliding time window approach before calculating the dFC within the spatial navigation brain network.Results:Compared to the balanced constitution group, the biased constitution SCD group showed significantly lower scores on the Mini-Mental State Examination (MMSE) ( z=-3.05, P=0.002) and the Auditory Verbal Learning Test (AVLT) measures: immediate recall ( z=-2.12, P=0.035), short-delay recall ( z=-2.22, P=0.026), long-delay recall ( z=-2.88, P=0.004), cued recall ( z=-2.91, P=0.004), and recognition ( z=-2.20, P=0.028). They also exhibited significantly higher average error distances in ego-allocentric navigation ( z=-2.28, P=0.023), egocentric navigation ( z=-2.31, P=0.021), and delayed navigation ( z=-2.02, P=0.043). Participants with SCD who had a biased constitution also demonstrated significantly reduced dFC between the left parahippocampal gyrus (PHG) and left prefrontal cortex (PFC) ( t=2.43), right precuneus and right retrosplenial cortex (RSC) ( t=2.96), and left inferior parietal lobule (IPL) and left hippocampus ( t=2.42) (all P<0.05, Bonferroni-corrected). Conversely, the dFC was significantly increased between the right PHG and left PFC ( t=-2.29, P<0.05, Bonferroni-corrected). Significant correlations were also found in participants with SCD who had biased constitutions: the dFC between the left PHG and left PFC positively correlated with the egocentric navigation average total error ( r=0.34, P=0.030) and negatively correlated with the visuospatial memory cognitive domain ( r=-0.35, P=0.026); the dFC between the left IPL and left hippocampus negatively correlated with the egocentric navigation average total error ( r=-0.32, P=0.043); and the dFC between the right PHG and left PFC positively correlated with the delayed navigation average total error ( r=0.33, P=0.037). The area under the ROC curve for the combined differences in cognitive assessments, spatial navigation behavior, and navigation-related brain network dFC was 0.966 in predicting biased constitution versus balanced constitution in participants with SCD. Conclusions:Individuals with SCD and biased constitutions demonstrated poorer spatial navigation ability, possibly due to altered dFC within the spatial navigation brain network. Furthermore, the integrated model based on spatial navigation behaviors and dFC exhibited a high predictive value in distinguishing between individuals with SCD who had balanced and biased constitutions.

Objective:To evaluate the clinical efficacy of acupuncture combined with low-frequency repetitive transcranial magnetic stimulation (rTMS) in the treatment of heart and liver fire hyperactivity syndrome in children with tic disorder; To explore its effects on the levels of serum neurotransmitters in children.Methods:A randomized controlled trial study was conducted. A total of 86 children with heart and liver fire hyperactivity syndrome of tic disorder in our hospital from March 2022 to March 2024 were selected as the observation objects and divided into 2 groups using the random number table method, with 43 cases in each group. The control group was treated with rTMS, while the observation group was treated with combined acupuncture on the basis of the control group. Both groups were treated continuously for 8 weeks. The TCM syndrome scores were conducted before and after the treatment respectively. The Yale Comprehensive Tic Severity Scale (YGTSS) was used to evaluate the severity of clinical symptoms, and the levels of serum γ -aminobutyric acid (γ-GABA), dopamine (DA), and 5-hydroxytryptamine (5-HT) were detected by ELISA. The adverse reactions during the treatment period were recorded and the clinical efficacy was evaluated.Results:The total effective rate was 90.70% (39/43) in the observation group and 72.09% (31/43) in the control group, with statistical significance ( χ2=4.91, P=0.027). After treatment, the scores of convulsion and peristalsis, flushed face and ears, irritability and anger, and red tongue with yellow coating in the observation group were lower than those in the control group ( t values were 3.80, 2.94, 3.26, and 4.22 respectively, P<0.01), and the scores of vocal tics, motor tics and the total score were lower than those in the control group (t values were 7.97, 5.23, and 6.44 respectively, P<0.01). After treatment, the level of γ-GABA in the observation group [(9.72±2.04) μg/L vs. (8.13±1.87) μg/L, t=3.77] was higher than that of the control group ( P<0.01), and DA [(8.98±1.94) μg/L vs. (12.10±2.27) μg/L, t=6.85], levels of 5-HT [(15.20±3.87) μg/L vs. (19.93±3.97) μg/L, t=5.59] were lower than those in the control group ( P<0.01). During the treatment period, the incidence of adverse reactions was 11.63% (5/43) in the observation group and 9.30% (4/43) in the control group, without statistical significance ( χ2=0.12, P=0.725). Conclusion:Acupuncture combined with rTMS can alleviate the tic symptoms of children of tic disorder with heart and liver fire hyperactivity syndrome, improve the neurotransmitter levels and main TCM syndromes of the children, enhance the clinical efficacy and have good treatment safety.

BACKGROUND:MicroRNA(miRNA)levels are closely related to cell apoptosis and proliferation,extracellular matrix metabolism and inflammatory response in intervertebral disc cells.However,the specific role of miR-142-3p in lumbar intervertebral disc degeneration remains unclear. OBJECTIVE:To investigate the correlation between the expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in nucleus pulposus tissue and degree of human lumbar intervertebral disc degeneration. METHODS:A total of 82 patients with lumbar intervertebral disc degenerative diseases in Suzhou Ninth People's Hospital from January 2020 to March 2022 were collected as the study subjects,all of whom underwent MRI examination before operation.According to the Videman classification,the patients were divided into mild degeneration group(n=36),moderate degeneration group(n=26)and severe degeneration group(n=20).Eighty-two specimens of the nucleus pulposus were obtained.The mRNA expression of miRNA-142-3p as well as the mRNA and protein expression of mixed lineage kinase 3,interleukin-1β,type I collagen,type II collagen in nucleus pulposus tissue were detected by qPCR and western blot assay.The correlation between the degree of human lumbar intervertebral disc degeneration and the expression levels of miRNA-142-3p,mixed lineage kinase 3,and interleukin-1β was also assessed using the Spearman correlation coefficient method.Thirty adult Sprague-Dawley rats were divided into sham-operated group(executed after puncturing skin and muscle only),mild degeneration group(executed 1 week after puncturing Co7/8 segments)and severe degeneration group(executed 2 weeks after puncturing Co7/8 segments),with 10 rats in each group.After that,we detected the protein expression of mixed lineage kinase 3 and interleukin-1β as well as the gene expression of miRNA-142-3p,mixed lineage kinase 3 and interleukin-1β in the nucleus pulposus tissue. RESULTS AND CONCLUSION:In human nucleus pulposus tissue,the miRNA-142-3p expression ranked from high to low as follows:mild degeneration group>moderate degeneration group>severe degeneration group(P<0.05);the gene and protein expression of mixed lineage kinase 3 and interleukin-1β from low to high was as follows:mild degeneration groupmoderate degeneration group>severe degeneration group(P<0.05).Spearman correlation analysis showed that the degree of disc degeneration was negatively correlated with miRNA-142-3p expression(P<0.05)and positively correlated with mixed lineage kinase 3 and interleukin-1β expression(P<0.05).In rat nucleus pulposus tissue,compared with the sham-operated group,the expression of mixed lineage kinase 3 and interleukin-1β gene and protein was elevated in the mild degeneration group(P<0.05)while miRNA-142-3p expression was decreased(P<0.05);compared with the mild degeneration group,the expression of mixed lineage kinase 3 and interleukin-1β gene and protein was increased in the severe degeneration group(P<0.05)while miRNA-142-3p expression was decreased(P<0.05).To conclude,the degree of human lumbar intervertebral disc degeneration is negatively correlated with miRNA-142-3p expression and positively correlated with mixed lineage kinase 3 and interleukin-1β expression in nucleus pulposus tissue.

Objective:To investigate the efficacy and safety of venetoclax (VEN) combined with hypomethylating agents (HMA) in the treatment of blastic plasmacytoid dendritic cell neoplasms (BPDCN).Methods:A retrospective case series study was conducted. The clinical data of 5 patients with BPDCN treated with VEN combined with azacitidine (AZA) or decitabine (DAC) in the First Affiliated Hospital of Soochow University and Suzhou Hongci Blood Disease Hospital from February 2017 to July 2023 were collected, and the therapeutic effect, adverse reaction and prognosis of all 5 patients were summarized.Results:All 5 BPDCN patients were male with the median onset age [ M ( Q1, Q3)] of 66 years (51 years, 73 years), of which 4 cases were presented with skin lesions and 1 case was presented with lymphadenopathy as the primary symptom. As for the treatment, 3 patients were initially treated with VEN in combination with AZA induction regimen, among which 2 patients achieved complete remission with incomplete blood count recovery (CRi) after 2 cycles of treatment, survived for 26.5 months and 14.6 months, respectively and finally died, and 1 patient achieved partial remission after 1 cycle of treatment and he still survived after 3-month follow-up; 1 patient was initially treated with VEN in combination with DAC induction regimen, and achieved clinical complete remission of non-active disease with residual skin abnormalities after 2 cycles of treatment followed by allogeneic hematologic stem cell transplantation (allo-HSCT) and he was in the state of disease-free survival for 15-month; and another 1 patient experienced a relapse after treatment with acute lymphocytic leukemia-like regimen in combination with allo-HSCT and again achieved CRi after 2 treatment courses of VEN in combination with AZA regimen, and he was in the state of disease-free survival for 30-month follow-up. Treatment-related haematological adverse effects of VEN combined with HMA were mainly neutropenia with fever, reduction of hemoglobin and thrombocytopenia; and non-haematological adverse effects were mainly gastrointestinal reactions such as nausea and vomiting. These adverse events improved with symptomatic supportive therapy, and no treatment-related deaths occurred. Conclusions:BPDCN patients who are unable to tolerate intensive chemotherapy regimens at initial time of diagnosis may attempt induction therapy with VEN+HMA regimen, which has a manageable adverse reaction and may serve as a bridge to allo-HSCT.

Patients with severe trauma require an extremely timely treatment and transfusion plays an irreplaceable role in the emergency treatment of such patients. An increasing number of evidence-based medicinal evidences and clinical practices suggest that patients with severe traumatic bleeding benefit from early transfusion of low-titer group O whole blood or hemostatic resuscitation with red blood cells, plasma and platelet of a balanced ratio. However, the current domestic mode of blood supply cannot fully meet the requirements of timely and effective blood transfusion for emergency treatment of patients with severe trauma in clinical practice. In order to solve the key problems in blood supply and blood transfusion strategies for emergency treatment of severe trauma, Branch of Clinical Transfusion Medicine of Chinese Medical Association, Group for Trauma Emergency Care and Multiple Injuries of Trauma Branch of Chinese Medical Association, Young Scholar Group of Disaster Medicine Branch of Chinese Medical Association organized domestic experts of blood transfusion medicine and trauma treatment to jointly formulate Chinese expert consensus on blood support mode and blood transfusion strategies for emergency treatment of severe trauma patients ( version 2024). Based on the evidence-based medical evidence and Delphi method of expert consultation and voting, 10 recommendations were put forward from two aspects of blood support mode and transfusion strategies, aiming to provide a reference for transfusion resuscitation in the emergency treatment of severe trauma and further improve the success rate of treatment of patients with severe trauma.

Objective To develop an evidence-based practice program for ICU eye care and evaluate its application effect using Stetler model of research utilization.Methods The systematic search was carried out in domestic and foreign guid elines,systematic reviews,evidence summaries,expert consensuses on eye care for ICU patients.The quality of the included literature was evaluated and the evidence was summarized.The evidence based on expert advice,clinical context and stakeholder opinions was screened.According to Stetler model of research utilization,the evidence translation/application was formulated from 3 aspects,including method,level and type of evidence application,and the evidence translation was implemented using a stepwise trial design.Five ICUs in a tertiary hospital in Zhejiang Province were selected,and the order of enrollment of each ICU was determined by computer-generated random numbers from April to september,2022.In the first month,all ICUs were in pre-evidence-based practice period,and in the second month,an ICU was trained and entered the evidence-based practice period.Until the 6th month,all ICUs entered the evidence-based practice period.Then the rate of ocular symptoms and implementation rate of eye care measures were compared before and after EBP.Results A total of 1 540 patients were included.With regard to the implementation rate of eye care measures,the rate of lubricant use and suspected ocular infection management in patients at high risk for ocular complications in evidence-based practice period was significantly higher compared with pre-evidence-based practice period(P＜0.001),and no statistically significant difference was found in the rate of eyelid closure.The incidence of conjunctival exposure,subconjunctival hemorrhage,conjunctival congestion,and ocular discharge in non-neurology critical care patients decreased compared with pre-evidence-based practice period(P＜0.05),and the incidence of conjunctival edema and conjunctival congestion in NICU patients decreased compared with pre-evidence-based practice period as the intervention continued(P＜0.001).Conclusion Evidence-based practice in eye care for ICU patients using Stetler model of research utilization can standardize the practice of eye care for ICU patients and improve the quality of care.

Objective To evaluate the clinical application value of transcatheter arterial methylene blue angiography in the localization of lower gastrointestinal arterial bleeding.Methods Ten patients with lower gastrointestinal arterial bleeding received interventional celiac artery angiography.After the bleeding responsible arteries were identified,a microcatheter was super-selectively placed in the bleeding responsible artery.During surgical procedure,the methylene blue solution was injected through the microcatheter to display the bleeding segment of the intestinal tract,providing precise localization of the bleeding intestinal segment for surgical resection.Results Transcatheter arterial methylene blue angiography could clearly display the bleeding segment of the intestinal tract.The bleeding segments of the intestinal tract in the 10 patients were quickly and accurately removed.After surgery,the gastrointestinal bleeding stopped,and no surgery-related complications occurred.Conclusion Transcatheter arterial methylene blue angiography can accurately detect the arterial bleeding segment of the lower gastrointestinal tract,which provides precise localization for quickly removing the bleeding segment of intestinal tract,therefor,this technique is worthy of widespread clinical application.(J Intervent Radiol,2023,32:1230-1232)
