Objective:To investigate the changing trends and influencing factors of two kinds of absorbable hemostatic gauze in clinical use based on real-world data,so as to provide a reference for the refined management of absorbable hemostatic gauze.Methods:Data of surgical samples of a total of 34658 pieces of absorbable hemostatic gauzes,whose brand include brand A and brand B,in 27,468 surgeries of the Affiliated Wuxi People's Hospital of Nanjing Medical University between January 1,2015 and December 31,2023 were selected.In them,12729 surgeries used hemostatic gauzes(18,457 pieces)of brand A,and 14,739 surgeries used hemostatic gauzes(16,201 pieces)of brand B.The changing trends of the usage and cost of two kinds of absorbable hemostatic gauzes were compared and analyzed,which correlations of that with the different indicators of workload also were compared and analyzed.Results:The usage amount of absorbable hemostatic gauze of brand B increased annually,which had higher average costs per surgery but lower average usage amount per surgery.Brand B was mainly used in surgery of level-4.Both the usage amounts of brand A(18,457 pieces)and brand B(16,201 pieces)showed a positive correlation with the proportion of patients with difficult and critically ill(r=0.232,0.593,P<0.05),as well as with the proportion of medical consumables expenditure(r=0.334,0.491,P<0.05).Compared to brand A,brand B demonstrated a stronger positive correlation with the proportion of patients with difficult and critically ill,and the proportion of consumables expenditure.However,there was no significant correlation between the usage amount of each brand and the number of inpatients who received surgeries(P>0.05).The usage amount of absorbable hemostatic gauze of each brand was negative correlation with the proportion of pharmaceutical expenditure(r=-0.538,-0.696,P<0.05).Conclusion:The evaluation based on real-world data for clinical use of absorbable hemostatic gauze can reveal that brand B is gradually replacing brand A in clinical application.In clinical practice,the surgery with higher-level more prefers to use brand B.This result can guide management departments to monitor the use of absorbable hemostatic gauze.However,the balance between clinical demand and cost-effectiveness also should be considered,so as to promote the rational use of hemostatic materials,and ensure effective allocation for resource.

Brain imaging abnormalities are present in schizophrenia (SZ) and bipolar disorder (BD), demonstrating disease-specific changes, yet they also share similarities in certain brain regions or functional characteristics, with SZ potentially exhibiting more extensive brain damage compared to BD. Structural magnetic resonance imaging (MRI) studies demonstrated widespread gray matter reductions in SZ, particularly in the prefrontal and temporal lobes. In BD, gray matter thickening was observed in the prefrontal lobes during manic episodes, while a reduction in gray matter was noted in the amygdala and hippocampus during depressive episodes. Both SZ and BD exhibited increased ventricular volume and reduced overall brain volume. Functional MRI studies revealed reduced functional connectivity in the prefrontal and temporal lobes in SZ, with decreased global and local efficiency in brain regions such as the hippocampus and cingulate gyrus. BD showed enhanced connectivity in the anterior cingulate gyrus and the default mode network (DMN). Both SZ and BD demonstrated altered functional connectivity in areas such as the striatum, salience network, central executive network and DMN. Diffusion tensor imaging studies showed decreased fractional anisotropy (FA) in the corpus callosum of SZ, with a decrease in FA in the left fronto-occipital fasciculus in BD. Both SZ and BD exhibited reduced FA in the uncinate fasciculus and corpus callosum. Magnetic resonance spectroscopy revealed decreased concentrations of glutathione, N-acetylaspartate (NAA) and inositol in the anterior cingulate gyrus of SZ. In BD, glutathione and inositol concentrations were elevated in the anterior cingulate gyrus, while NAA levels decreased during depressive episodes and increased during remission. Both SZ and BD showed increased levels of glutamate and gamma-aminobutyric acid in the prefrontal cortex. This article provides a review of the current evidence on the differences and similarities in multimodal magnetic resonance brain imaging between SZ and BD, aiming to offer a reference for future exploration of neuroimaging biomarkers and the neurobiological mechanisms of SZ and BD.

Objective:To construct an estimating equation to accurately reflect the aging phenomenon of the glomerular filtration rate(GFR).Methods:Healthy subjects receiving physical examinations at the First Affiliated Hospital of Nanjing Medical University between January 2017 and April 2018 were included in the study, and the aging phenomenon of renal function indicators such as serum creatinine(Scr)was used as the reference standard to evaluate the accuracy of four Scr-based GFR equations during GFR aging, including the full age spectrum(FAS)equation, the Chronic Kidney Disease Epidemiology Collaboration(CKD-EPI)equation, the Osaka equation and the Xiangya equation.Results:Of 37 636 individuals receiving physical examinations, 6 534 met the criteria specified in this study.Scr, serum urea nitrogen, serum uric acid, and serum albumin showed a significant aging phenomenon( H=191.640, 196.693, 83.271, 414.585, P<0.001 for all).The GFR estimated by the four equations all decreased with aging, but the starting point and rate of decline were significantly different.The GFR aging phenomenon estimated by the FAS equation was closer to the trend of renal function indicators. Conclusions:The FAS equation may be more applicable to healthy people to understand the aging phenomenon of GFR.

Schizophrenia is a chronic disabling disease of unknown etiology. Its neuroimaging abnormalities have been confirmed by a large number of studies. However, when these structural abnormalities occur and how they develop over time are unclear. The relationship between structural abnormalities and antipsychotic treatment needs to be further explored. Longitudinal studies on the brain structure of clinical high risk for psychosis, first-episode schizophrenia and chronic schizophrenia, exploring the influence of drug therapy on them, are helpful to construct the trajectories of brain structure changes in the whole course of schizophrenia and dynamically track the brain structure changes, so as to further explore the pathophysiology of schizophrenia. This article reviews the longitudinal research progress of brain structure changes in patients with schizophrenia.

Objective:To explore differences of resting brain regional homogeneity (ReHo) between patients with major depressive disorder (MDD) and their siblings.Methods:From January to December 2013, the resting-state functional magnetic resonance imaging (fMRI) data of 87 patients with MDD and 21 healthy siblings were collected.DPABI v5.1 software was used to preprocess the resting-state fMRI data, and ReHo maps of each subject was obtained. A two-sample t-test was used to compare differences between the patients with MDD and their siblings in ReHo values throughout the brain. ReHo values within the significant brain regions were extracted out, and used to calculate Spearman correlation with the total score of 17-items Hamilton depression rating scale(HAMD-17) in the patients with MDD and their siblings respectively.The software of SPSS 20.0 was used for statistical analysis. Results:The patients with MDD exhibited lower ReHo values in the precuneus extending to the posterior cingulate cortex (PCu/PCC) compared with their siblings (cluster-size=126 voxel, cluster-level PFDR=0.033; MNI: x=-4, y=-58, z=38, t=4.30). ReHo values of the PCu/PCC in patient with MDD were positively correlated with the severity of depressive symptoms ( r=0.255, P=0.021). Conclusion:Compared with the siblings, local brain activity of the PCu/PCC in the patients with MDD was decreased, and related to the severity of depressive symptoms. It is helpful to further reveal the intrinsic neural mechanism of MDD.

As an important part of tumor microenvironment, neutrophils are poorly understood due to their spatiotemporal heterogeneity in tumorigenesis. Here we defined, at single-cell resolution, CD44-CXCR2- neutrophils as tumor-specific neutrophils (tsNeus) in both mouse and human gastric cancer (GC). We uncovered a Hippo regulon in neutrophils with unique YAP signature genes (e.g., ICAM1, CD14, EGR1) distinct from those identified in epithelial and/or cancer cells. Importantly, knockout of YAP/TAZ in neutrophils impaired their differentiation into CD54+ tsNeus and reduced their antitumor activity, leading to accelerated GC progression. Moreover, the relative amounts of CD54+ tsNeus were found to be negatively associated with GC progression and positively associated with patient survival. Interestingly, GC patients receiving neoadjuvant chemotherapy had increased numbers of CD54+ tsNeus. Furthermore, pharmacologically enhancing YAP activity selectively activated neutrophils to suppress refractory GC, with no significant inflammation-related side effects. Thus, our work characterized tumor-specific neutrophils in GC and revealed an essential role of YAP/TAZ-CD54 axis in tsNeus, opening a new possibility to develop neutrophil-based antitumor therapeutics.
