ObjectiveTo explore the changes in color， odor and chemical components during wine-processing of Chuanxiong Rhizoma（CR）， identify differential markers， and provide a basis for standardizing the process and establishing quality standards. MethodsFifteen batches of CR samples from 4 producing areas were collected. Colorimeter and electronic nose were used to detect the color changes and odor components of CR before and after wine-processing. Multivariate statistical methods including partial least squares-discriminant analysis（PLS-DA）， principal component analysis（PCA）， discriminant factor analysis（DFA） and Fisher discriminant analysis were applied to identify wine-processed CR at different processing stages and establish discriminant models， and differential components were screened out based on variable importance in the projection（VIP） value1. Then， high performance liquid chromatography（HPLC） was employed to detect the content changes of four components（ferulic acid， senkyunolide I， senkyunolide A and ligustilide） during the processing stages. ResultsThe differences of wine-processed CR at various stages were primarily reflected in color parameters L^*（brightness value）， a^*（red-green value） and b^*（yellow-blue value）. Based on chromaticity differences， the color reference ranges were established for moderately processed CR， including L^* of 46.75-48.24， a^* of 5.37-6.07 and b^* of 20.32-21.70. In odor analysis， DFA revealed significant differences among processing stages， and 11 odor markers were identified， with four differential markers（4-hydroxy-3-butylphthalide， isopropyl butyrate， L-limonene and 1-methoxyhexane） based on VIP values. HPLC results showed that there was no significant difference of the four components except for ligustilide in wine-processed CR at different stages. ConclusionThis study achieved rapid identification of wine-processed CR with different processing degrees by electronic sensory technology and differential component content detection， with discrimination accuracy rates of 92.4% and 93.272% for color and odor， respectively. This paper also established the reference ranges of main colorimetric parameters for wine-processed CR at different stages， and four differential components were screened out， providing a basis for standardizing the processing of wine-processed CR and establishing quality standards for this decoction pieces.

Extracellular vesicles(EVs)are nanoscale membrane vesicles released by cells that carry bioactive molecules such as proteins and nucleic acids. They play a key role in intercellular communication. In recent years, they have shown significant potential in the diagnosis and treatment of corneal and ocular surface diseases. As diagnostic biomarkers, EVs derived from tears or other sources can reflect disease-specific characteristics, providing a basis for the early disease detection. In terms of therapy, mesenchymal stem cells(MSCs)-derived EVs deliver miRNAs to modulate inflammatory pathways, promote corneal epithelial repair, and inhibit fibrosis. Furthermore, as natural drug vehicles, EVs enable precise delivery of therapeutic agents and promote corneal wound healing. This review systematically summarizes the recent research advances in the application of EVs in the field.

Objective: : Baculovirus inhibitory of apoptosis repeat-containing 5 (BIRC5) is critically implicated in various types of tumors. However, the specific mechanisms by which it operates in glioma are yet to be fully understood. Methods: : The data sourced from The Cancer Genome Atlas and Gene Expression Omnibus were merged and analyzed using the R software to investigate the relationship between BIRC5 expression and prognosis and diagnosis outcomes. This exploration was conducted utilizing various biological information repositories. The correlation between BIRC5 and immunity was obtained based on TIMER and TISIDB databases. Results: : Gliomas displayed a markedly elevated level of BIRC5 expression compared to adjacent tissues. Patients with glioma who exhibit elevated levels of BIRC5 experience poorer prognoses and shorter survival times. Subgroup classification further revealed that heightened expression of BIRC5 led to diminished overall survival. Analysis of logistic regression and COX indicated that expression of BIRC5 serves as a risk factor in glioma development. Functional enrichment pathways showed that the 72 hub genes related to BIRC5 were mainly closely related to nuclear division, spindle, tubulin binding, and cell cycle in glioma patients. BBIRC5 methylation suggested that BIRC5 might influence the immune response regulation and the tumor microenvironment within gliomas. BIRC5 is associated with many chemicals. Additionally, studies conducted using cell experiments and pathological sections have consistently shown that BIRC5 expression is higher in tumor cells compared to normal cells and tissues. Conclusion : BIRC5 holds promise as a valuable tool in the diagnosis, prognosis, and management of gliomas.

Objective To investigate the impact of minocycline(MC)on myocardial cell damage in rats with chronic heart failure(CHF)by regulating the hypoxia-inducible factor 1α(HIF-1α)/B-cell lymphoma-2/adenovirus E1B 19-kDa interacting protein(BNIP3).Methods All rats were randomly divided into Sham,CHF,positive drug(LP),low dose MC,high dose MC(HMC),and HMC+HIF-1α activator(DMOG)groups.Cardiac function was detected using echocardiography.HE staining,transmission electron microscopy,and TUNEL assay were used to evaluate myocardial pathology and apoptosis.Enzyme-linked immunosorbent assay was applied to quantify tumor necrosis factor α(TNF-α),interleukin-1β,superoxide dismutase(SOD),and malondialdehyde(MDA).Quantitative real-time PCR was used to detect the mRNA levels of Bcl-2 and Bcl-2-related X protein(Bax),while Western blotting was applied to detect the expres-sion of HIF-1α,BNIP3,Beclin-1,and microtubule-associated protein 1 light chain 3(LC3)proteins.Results Compared to rats in the sham group,rats from the CHF group exhibited increased left ventricular end-diastolic diameter(LVEDD),left ventricular end-systolic diameter(LVESD),cell apoptosis rate,TNF-α,IL-1β,MDA,Bax,HIF-1α,BNIP3,Beclin-1,and LC3Ⅱ/Ⅰwith decreased left ventricular ejection fraction(LVEF),left ventricular shortening fraction(LVFS),SOD,and Bcl-2 levels(P<0.05).Compared with CHF group,rats from LP group,LMC group and HMC group exhibited decreased levels of LVEDD,LVESD,apoptosis rate,TNF-α,IL-1β,MDA,Bax,HIF-1α,BNIP3,Beclin-1,LC3Ⅱ/Ⅰ,and increased levels of LVEF,LVFS,SOD and Bcl-2(P<0.05).DMOG attenuated the protective effect of high-dose MC on myocardial cell damage in rats of the CHF group(P<0.05).Conclusion MC improves myocardial cell damage in rats of CHF group by inhibiting the HIF-1α/BNIP3 signaling pathway.

Objective:To investigate the differences of the glymphatic system (GS) function between patients with mesial temporal lobe epilepsy with hippocampal sclerosis (mTLE-HS) and healthy controls and between different seizure types by using diffusion tensor imaging along perivascular space (DTI-ALPS), and to analyze the correlation between GS function and the course of disease, as well as the efficacy of predicting the surgical outcome.Methods:This study was a cross-sectional study. A total of 171 patients with mTLE-HS (mTLE-HS group) and 75 healthy volunteers (HC group) were retrospectively enrolled from July 2009 to July 2021 at Jinling Hospital, Affiliated Hospital of Medical School, Nanjing University. The general information of all subjects, such as seizure type (partial seizure, secondary generalized seizure), surgical outcome, etc., was analyzed. The 3D magnetization prepared rapid gradient echo T 1WI and DTI sequence images were collected. The VBM analysis method was used to segment cerebrospinal fluid and calculate the volume. The ALPS index of the bilateral brain was calculated using the Atlas-based DTI-ALPS method. Independent sample t-test or paired t test were used to compare the ALPS index between the mTLE-HS group and HC group, and between patients with different seizure types. Pearson correlation analysis was used to analyze the correlation between bilateral ALPS index and disease duration in mTLE-HS group. The predictive value of the ALPS index for surgical outcomes was evaluated by receiver operating characteristics curve and area under the curve. Results:Among the 171 mTLE-HS patients, 98 patients were mTLE with left-side HS (mTLE-LHS) and 73 patients were mTLE with right-side HS (mTLE-RHS); 37 patients underwent surgical treatment, including 27 with good prognosis and 10 with poor prognosis. Compared with the HC group, the left-side ALPS index of mTLE-LHS and mTLE-RHS were both decreased ( P<0.05). The right-side ALPS index in mTLE-RHS was lower than that in the HC group ( P<0.001). There was no significant difference in the right-side ALPS index between mTLE-LHS and HC group ( P=0.080). The ALPS index on the affected side of patients with secondary generalized seizures was significantly lower than that of patients with only partial seizures (all P<0.05), but the difference in ALPS index on the healthy side was not statistically significant( P>0.05). The left-side and right-side ALPS index in mTLE-LHS were negatively correlated with disease duration ( r=-0.272, P=0.007; r=-0.307, P=0.002), but no significant correlation was found between the left-side or right-side ALPS index in mTLE-RHS (all P>0.05). The DTI-ALPS index on the affected side in mTLE-HS patients exhibited good diagnostic accuracy for surgical outcome classification, with an area under the curve of 0.778. Conclusions:The patients with mTLE-HS exhibit dysfunction of the GS, and the degree of impairment is related to the type of seizure and the course of epilepsy. The ALPS index, which characterizes the function of GS, demonstrates good diagnostic accuracy for classifying surgical outcomes.

Objective:To evaluate the topological alterations of resting-state brain networks in patients with idiopathic generalized epilepsy with generalized tonic-clonic seizure (IGE-GTCS) using minimum spanning tree (MST) based on graph theoretic analysis, and to further analyze the relationships between topological features, duration, and antiepileptic drug response.Methods:This study was a cross-sectional study. Retrospectively, 75 IGE-GTCS patients and 37 healthy controls (HC) who underwent brain MR imaging at the Affiliated of Nanjing University Medical School Drum Tower Hospital from January 2013 to December 2020 were enrolled. IGE-GTCS patients were grouped into well-controlled subgroup (WC; n=55) and drug-resistant subgroup (DR; n=20) according to their response to antiepileptic drugs. Firstly, the time series correlations between 116 regions of the whole brain of each subject were calculated to construct functional connectivity matrices. For each functional connectivity matrix, the Kruskal algorithm was used to MST, and the topological metrics of each MST were calculated, including leaf fraction, tree hierarchy, and diameter. The comparison of MST topological metrics between the two groups was performed using two-sample t-test. Pearson correlation analysis was used to calculate the correlation between disease duration and MST metrics in the WC subgroup and the DR subgroup. Results:Compared with the HC group, the MST leaf fraction ( t=2.27, P=0.025) increased in the IGE-GTCS patient group, and the diameter decreased ( t=-2.24, P=0.027), there was no statistically significant difference in tree hierarchy between IGE-GTCS patient group and HC group ( t=0.98, P=0.328). The MST leaf fraction ( t=-2.39, P=0.019) and tree hierarchy ( t=-2.24, P=0.027) in the WC subgroup was decreased compared with the DR subgroup, while there was no statistically significant difference in diameter between WC subgroup and DR subgroup ( P=0.093). The correlation analysis showed the MST diameter in WC subgroup was significantly correlated with disease duration ( r=0.452, P<0.001), while the MST diameter in DR subgroup was not significantly correlated with disease duration ( r=-0.062, P=0.847). Conclusions:Patients with IGE-GTCS exhibit specific alterations in the global topology of brain network, characterized by increased centralization and efficiency. The effective antiepileptic drug treatment is associated with a recovery of brain network abnormalities.

Acute-on-chronic liver failure (ACLF) is an acute deterioration of liver function occurring on the basis of chronic liver disease, accompanied by failure of the liver and extrahepatic organs, and is associated with a high short-term mortality rate. Liver transplantation is the only curative treatment for patients with ACLF. However, the shortage of donor livers and limitations of the organ allocation system mean that only a minority of patients can receive transplants. The current organ allocation system based on the model for end-stage liver disease (MELD) score may underestimate the urgency of liver transplantation for ACLF patients. Therefore, it is urgent to develop better assessment tools to determine which ACLF patients are most likely to benefit from liver transplantation. This article reviews the current mainstream definitions of ACLF, the selection of candidates for liver transplantation in ACLF, and the prognostic scoring systems for liver transplantation in ACLF, both domestically and internationally, in order to provide a reference for the prognostic assessment of liver transplantation in ACLF patients.

Objective:To investigate renal impairment and ferroptosis due to severe blast injuries and related mechanism.Methods:The goats were placed 3 meters away from the center of an 8 kg TNT-equivalent explosive to carry out blast injury experiments.The physical parameters of blast waves were measured,and the pathological severity of blast injuries was graded and scored to assess the severity of injuries.Vital signs,blood gas parameters,and renal function markers were measured before injury and at 1,3,6,and 24 hours after injury.Renal tissue samples were collected at 24 hours after injury to prepare tissue sections,which were used to perform HE staining and measure the changes in the content of Fe2+and the expression of the ferroptosis-related marker proteins xCT and GPX4 in renal tissue,and Prussian blue staining was performed for renal tissue sections to investigate the mechanism associated with renal impairment and ferroptosis of renal cells.Results:Severe blast injuries accounted for the highest proportion of 47.2%in experi-mental goats,while mild,moderate,severe,and extremely severe injuries accounted for 2.8%,36.1%,47.2%,and 13.9%,respectively,and the pathologic severity score of blast injury was 2.56±0.15.For the goats after blast injury,there were significant increases in heart rate(F=12.750,P<0.01)and respiratory rate(F=6.500,P<0.01)and significant reductions in anal temperature(F=3.496,P<0.05),partial pressure of blood oxygen(F=24.630,P<0.01),and blood oxygen saturation(F=18.560,P<0.01),as well as significant increases in the levels of blood uric acid(F=22.320,P<0.01),serum creatinine(F=15.350,P<0.01),and blood urea nitrogen(F=22.310,P<0.01).Compared with the control group,swelling of renal tubular epithelial cells and narrowing of tubular lumen were observed at 24 hours after blast injury,with a significant increase in the content of Fe2+in renal tissue(t=5.933,P<0.01),significant reductions in the relative expression protein levels of GPX4(t=7.924,P<0.01)and xCT(t=4.483,P<0.01)in renal tissue,and deposi-tion of a large amount of iron ions in renal tubular epithelial cells.Conclusion:Experimental goats placed 3 meters away from the cen-ter of an 8 kg TNT-equivalent explosive can cause severe blast inju-ries,resulting in the onset of hypoxia,renal impairment,and ferrop-tosis of renal tubular epithelial cells.
