The prevalence of metabolic dysfunction-associated steatotic liver disease (MASLD) is higher among individuals with inflammatory bowel disease (IBD) than in the general population. Emerging evidence indicates that the development of MASLD in patients with IBD may occur independently of traditional metabolic risk factors, suggesting a unique pathophysiological mechanism distinct from conventional MASLD pathways. Bile acids (BAs), which act as critical signaling molecules in enterohepatic circulation, play an essential role in maintaining gastrointestinal homeostasis through bidirectional gut–liver axis communication. These molecules are increasingly recognized as pivotal regulators in the progression of both MASLD and IBD. While previous studies have characterized the dynamics of BA in blood or fecal samples under both conditions, a comprehensive understanding of their metabolic profiles and the associated interactions within the gut–liver axis is still lacking. This review synthesizes current evidence from studies employing BA metabolomics to investigate IBD and MASLD. By focusing on BA signatures, we summarize conserved alterations between these two conditions and their potential mechanisms of disease progression. Our review advances understanding of BA-mediated pathways in IBD and MASLD, providing a foundation for assessing their roles in contributing to the pathogenesis of MASLD in patients with IBD.

Network Meta-analysis was conducted to evaluate the efficacy and safety of different traditional Chinese medicine injections combined with conventional western medicine in treatment of cerebral small vessel disease(CSVD). Computerized searches were conducted in PubMed, Cochrane Library, Web of Science, EMbase, CNKI, Wanfang, VIP, and SinoMed for randomized controlled trial(RCT) published in Chinese or English using traditional Chinese medicine injections to treat CSVD. The search time is from the inception to July 15, 2024. Literature screening and statistical analysis were conducted with NoteExpress 3.0.3, RevMan 5.3.5, and Stata 15.1.6. A total of 45 articles were included, involving 3 717 patients, with 1 944 patients in the treatment group and 1 773 patients in the control group. A total of 15 kinds of traditional Chinese medicine injections were involved. Network Meta-analysis indicated that,(1) in terms of improving clinical total effective rate, the best intervention in SUCRA was Ciwujia Injection + conventional western medicine.(2) In terms of reducing NIHSS scores, the best intervention in SUCRA was Xueshuantong Injection + conventional western medicine.(3) In terms of improving ADL scores, the best intervention in SUCRA was Danshen Injection + conventional western medicine.(4) In terms of improving MMSE scores, the best intervention in SUCRA was Xueshauntong Injection + conventional western medicine.(5) In terms of improving MoCA scores, the best intervention in SUCRA was Salvianolate Injection + conventional western medicine.(6) In terms of reducing plasma viscosity(PV), the best intervention in SUCRA was Danhong Injection + conventional western medicine.(7) In terms of reducing the hematocrit, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(8) In terms of reducing fibrinogen, the best intervention in SUCRA was Xuesaitong Injection + conventional western medicine.(9) In terms of reducing erythrocyte sedimentation rate(ESR), the best intervention in SUCRA was Danshen Injection + conventional western medicine.(10) In terms of reducing total cholesterol(TC), triglycerides(TG), and low-density lipoprotein(LDL), the best intervention in SUCRA was Danshen Injection + conventional western medicine. The radar chart results indicated that the advantage of Salvianolate Injection lies in improving cognitive function, while the advantage of Xueshuantong Injection lies in improving neurological function. The advantage of Xuesaitong Injection lies in improving hemodynamic parameters, and the advantage of Danshen Injection lies in improving behavioral ability, hemodynamics, and blood lipid levels. In terms of safety, there was no significant difference in the incidence of adverse reactions between the traditional Chinese medicine injection treatment group and the conventional western medicine group, and no serious adverse reactions occurred. The results showed that the combination of traditional Chinese medicine injections and conventional western medicine can effectively improve the clinical total effective rate, the neurological and cognitive functions, hemodynamic parameters, and blood lipid levels of patients suffering from CSVD. In addition, more double-blind, multi-center, large-sample RCT is needed to verify these findings and to provide more high-quality evidence on the efficacy and safety of traditional Chinese medicine injections for CSVD.

The antidepressant activity and molecular mechanisms of Yueju Wan volatile oil were investigated. The Yueju Wan volatile oil was extracted by using supercritical CO_2. Gas chromatography-mass spectrometry(GC-MS) combined with network pharmacology identified 28 chemical constituents in Yueju Wan volatile oil, primarily terpenes and lactones. A total of 123 overlapping targets were associated with depression, including core targets of interleukin-1β(IL-1β), signal transducer and activator of transcription 3(STAT3), and caspase-3(CASP3). These targets were mainly involved in the prolactin, advanced glycation end products/receptor(AGE/RAGE), and phosphoinositide 3-kinase/protein kinase B(PI3K/Akt) signaling pathways. A reserpine-induced depression mouse model was established to evaluate the therapeutic effects and mechanisms of Yueju Wan volatile oil. The effects of Yueju Wan volatile oil on depression-like behavior in mice were evaluated by analyzing body mass, body temperature index, tail suspension immobility time, forced swimming immobility time, and sucrose preference. Hematoxylin-eosin(HE) staining revealed neuronal protection of Yueju Wan volatile oil in the brain of mice. Enzyme-linked immunosorbent assay(ELISA) and Western blot were employed to detect the protein expression of AGEs, IL-1β, phosphorylated PI3K(p-PI3K), Akt, phosphorylated Akt(p-Akt), nuclear factor κB(NF-κB), and brain-derived neurotrophic factor(BDNF). Behavioral evaluation showed that Yueju Wan volatile oil could effectively control the decline of body mass and body temperature of depressed mice, reduce tail suspension and swimming immobility time, and enhance their preference for sucrose. Histopathological examination showed that Yueju Wan volatile oil could alleviate the neuronal damage in CA1 and dentate gyrus(DG) of the hippocampus of mice. ELISA and Western blot results showed that Yueju Wan volatile oil could significantly increase the protein expression levels of PI3K, Akt, and BDNF and significantly decrease the protein expression levels of AGEs, IL-1β, p-PI3K, p-Akt, and NF-κB in the hippocampus of mice. Furthermore, the p-PI3K/PI3K and p-Akt/Akt ratios were significantly decreased at medium and high doses. These findings suggest that the aromatherapy of Yueju Wan volatile oil can significantly improve reserpine-induced depression-like behavior in mice, which may be related to reducing the expression of neuronal membrane protein AGEs, reducing the phosphorylation levels of PI3K and Akt, inhibiting NF-κB entry into the nucleus, and alleviating the release of pro-inflammatory factors and nerve injury.

Objective: To retrospectively compare the impact of different intraoperative transfusion strategies for platelets and cryoprecipitate on perioperative blood usage and clinical outcomes in patients undergoing orthotopic heart transplant (OHT), thereby providing a reference for perioperative patient blood management. Methods: The clinical data of 65 patients who had undergone OHT at our hospital between 2020 and 2025 were retrospective collected. Patient demographics, underlying chronic conditions, and perioperative (preoperative, intraoperative, and postoperative) laboratory blood test results were analyzed. The transfusion volumes of intraoperative red blood cells, plasma, platelets, and cryoprecipitate were examined. Univariate and multivariate logistic regression models were employed to identify factors associated with perioperative outcomes. Results: A total of 65 patients received allogeneic blood transfusion during the perioperative period. The ultilization of intraoperative platelets and cryoprecipitate was as follows: simultaneous transfusion of both platelets and cryoprecipitate (at a 1∶1 ratio) was administered in 42 patients (64.62%), platelets alone in 12 patients (18.46%), and cryoprecipitate alone in 11 patients (16.92%). Patients who received simultaneous transfusion of platelets and cryoprecipitate (1∶1) (n=42) had a shorter ICU length of stay (32.45±10.18 d), while those who received either platelets or cryoprecipitate alone (n=23) had a significantly longer ICU length of stay (68±15.97 d). Patients receiving simultaneous intraoperative transfusion of platelets and cryoprecipitate also required fewer units of allogeneic red blood cells intraoperatively (median=4 units) and had a lower mortality rate (16.7%) than those receiving either product alone (26.1%), with a statistically significant difference (P=0.023). Multivariate logistic regression analysis indicated that the volume of cryoprecipitate transfused was an independent protective factor against postoperative allogeneic red blood cell transfusion (OR=0.344, 95% CI [0.177, 0.829], P=0.0159). Multivariate logistic regression also identified cryoprecipitate transfusion volume as an independent protective factor for ICU length of stay (OR=0.877, 95% CI [0.719, 0.986], P=0.0008), which was in line with the multivariate Cox regression results. Conclusion: In patients undergoing OHT, the intraoperative transfusion strategy for platelets and cryoprecipitate influences the volume of perioperative allogeneic red blood cell transfusion and patient mortality. Intraoperative cryoprecipitate transfusion volume is an independent protective factor against both postoperative allogeneic red blood cell transfusion and prolonged ICU length of stay. The establishment of a multidisciplinary collaborative blood management model, combined with the modification of perioperative blood utilization practices and the implementation of a comprehensive patient blood management strategy, can holistically ensure perioperative patient safety.

Objective: To evaluate the safety and efficacy of the emergency infusion protocol for universal red blood cells by analyzing its clinical application in patients treated at our hospital's war trauma and emergency center. Methods: Data were collected from 133 patients who received universal red blood cell transfusion in the war trauma center of our hospital from January 2016 to December 2024. The basic information, universal red blood cell transfusion volume, compatible blood components, transfusion volume, blood routine (Hb, Hct), liver and kidney function (ALT, AST, TBil, DBil, creatinine, etc.) and coagulation function (PT, APTT, Fib, etc.) before and after transfusion were retrospectively analyzed. Results: Among the 133 patients who received a total of 374 units of universal red blood cells, the 24-hour survival rate was 62.4% (83/133). Spearman correlation analysis showed a positive correlation between shock index and universal red blood cell transfusion volume (r=0.283, P<0.05). Patients were stratified by universal red blood cell transfusion volume (≤ 3 U vs ≥ 4 U). The low volume group had less homotypic red blood cell transfusion volume and total transfusion volume at different time points, and the difference was statistically significant: within 2 h [2(2, 4)vs 4(3, 7), P=0.033<0.05], 0~24 h [6(4, 9) vs 8(6, 14), P=0.028<0.05], total transfusion volume [13(8, 20)vs 19(12, 35), P=0.021<0.05]. No acute hemolytic transfusion reaction occurred within 24 hours after transfusion of universal red blood cell. Conclusion: Universal red blood cells are safe for use in emergency treatment. Furthermore, the shock index combined with the volume of universal red blood cells transfused can predict subsequent transfusion requirements and enables the early reservation of compatible blood, thereby preventing delayed resuscitation.

Objective:To investigate the risk factors for aggravation of type 2 diabetic foot ulcer and the correlation between the level of infection and the severity of the disease,as well as the association of the detection rate of bacteria and the types of bacteria with disease severity in patients with type 2 diabetic foot ulcer,and to provide individualized guidance for the prevention,diagnosis,and treatment of type 2 diabetic foot.Methods:A retrospective analysis was performed for the data of 150 patients with type 2 diabetic foot who were treated in Department of Endocrinology,The First Affiliated Hospital of Kunming Medical University,from October 2021 to June 2023,and according to the Wagner grade of diabetic foot,these patients were divided into mild group A(35 patients with Wagner grade 2),moderate group B(58 patients with Wagner grade 3),and severe group C(57 patients with Wagner grade 4).The clinical data of the three groups were analyzed.Results:The severity of type 2 diabetic foot ulcer was correlated with white blood cell count,neutrophil count,platelet count,monocyte count,globulin,alkaline phosphatase,neutrophil-lymphocyte ratio,monocyte-lymphocyte ratio,platelet-lymphocyte ratio,high-sensitivity C-reactive protein,procalcitonin,interleukin-6,erythrocyte sedimentation rate,hemoglo-bin,albumin/globulin ratio,lymphocyte count,cholinesterase,albumin,fasting blood glucose,gamma-glutamyl transferase,glycated he-moglobin,blood uric acid,high-density lipoprotein cholesterol,total cholesterol,triglycerides,and low-density lipoprotein cholesterol(P<0.05).The multivariate ordinal logistic regression analysis showed that the neutrophil-lymphocyte ratio and erythrocyte sedi-mentation rate were independent risk factors for the progression of Wagner grade of diabetic foot(P<0.05).For groups A,B,and C,the detection rate of bacteria in foot ulcer secretion tended to increase with the severity of diabetic foot,with the highest detection rate in group C,followed by groups B and A.A total of 31 types of bacteria were detected in the three groups,and the proportion of Gram-positive bacteria was higher than that of Gram-negative bacteria,with Staphylococcus aureus accounting for the highest proportion of 27.72%in all samples.Conclusion:High-sensitivity C-reactive pro-tein,procalcitonin,interleukin-6,and erythrocyte sedimentation rate increase with the progression of the Wagner grade of diabetic foot,and neutrophil-lymphocyte ratio and erythrocyte sedimentation rate are independent risk factors for the progression of the Wagner grade of diabetic foot.The detection rate of bacteria in foot ulcer secretion tends to increase with the Wagner grade of diabetic foot,and Gram-positive bacteria account for a higher proportion than Gram-negative bacteria,with Staphylococcus aureus accounting for the highest proportion.

Objective To evaluate the efficacy of elastic appliances in the early correction of Class Ⅱmalocclusions in the replacement dentition.Methods A total of 15 children aged 7-9 years who were admit-ted to the Affiliated Stomatology Hospital of Southwest Medical University from June 2018 to August 2023 were selected as the observation group,and 15 children who were consulted but not treated in the hospital dur-ing the same period were selected as the control group.The changes of bone tissue,dental and alveolar tissue,soft tissue and occlusal relationship before and after treatment were evaluated in the two groups.In addition,X-ray images of the observation group were collected every 8 to 10 months for the whole process dynamic mo-nitoring.Results Before treatment,there was no significant difference in all indexes between the two groups(P＞0.05).After treatment,there were statistical significances in the upper and lower alveolar base Angle(ANB),mandibular branch length(GO-CO),mandibular height(ANS-Me),mandibular position(S-GO),up-per central incisor inclination(U1-NA Angle),upper central incisor inclination convexity(U1-NA),lower central incisor process distance(L1-APo),the Z Angle and FH-N'Pg'Angle of soft tissue between the two groups(P＜0.05).After treatment,the covering OB and covering OJ in the observation group were lower than those in the control group,and the proportion of ClassⅠ patients in molar relationship was higher than that in the control group,with statistical significance(P＜0.05).After 3-4 years of treatment,ANB gradual-ly decreased,and the anterior-basilar plane-mandibular plane Angle(SN-MP)remained basically stable,and had a slight decreasing trend in the later period.The U1-NA Angle and the lower central incisor inclination(L1-NB Angle)were close to the normal mean during the whole treatment.Conclusion Using elastic appli-ances to treat patients with early replacement Class Ⅱ malocclusion,after 3-4 years monitoring and guid-ance,it can effectively improve the molar relationship,promote forward jaw growth,and create a harmonious and aesthetically pleasing facial soft tissue.

Arsenic is a semi-metal,and lipid-soluble arsenic compounds are one of the widespread forms in the environment and food chain,but there is a lack of standards for lipid-soluble arsenic compounds,which is one of the bottlenecks in the current analytical detection and toxicological studies of organic arsenic.In this study,four saturated arsenic-containing hydrocarbons,AsHC 318,AsHC 332,AsHC 346,and AsHC 374(The number is relative molecular mass),were successfully synthesized in three steps by using dimethylarsinic acid,potassium iodide,sodium hydroxide,and four brominated alkanes(1-Bromotetradecane,1-bromopentadecane,1-bromohexadecane,and 1-bromooctadecane)as raw materials.The structures of these four saturated arsenic-containing hydrocarbons were characterized by proton nuclear magnetic resonance(1H NMR)spectroscopy,13C nuclear magnetic resonance(13C NMR)spectroscopy,and high-resolution mass spectrometry(HR-MS).The yields of the method were 8%-10%,and the synthesized compounds could be used in subsequent toxicity evaluation experiments to assess the toxic effects and mechanisms of action of arsenic-containing hydrocarbons.This study provided an effective method for synthesis of arsenic-containing hydrocarbons,enriching the synthesis methods of arsenic-containing hydrocarbons,and provided raw materials for the subsequent toxicological studies of arsenic-containing hydrocarbons.

Accurate analysis of metal nanoparticles(MNPs)in sediments is a prerequisite for assessing the ecological risks of MNPs in aquatic environmental sediments.In this study,an analytical method for quantitative detection of concentration and particle size distribution of silver-containing nanoparticles(Ag-NPs),zinc-containing nanoparticles(Zn-NPs),cerium-containing nanoparticles(Ce-NPs),and titanium-containing nanoparticles(Ti-NPs)in sediments was established based on ultrasonic extraction-single particle inductively coupled plasma mass spectrometry(SP-ICP-MS).The effects of sample preparation conditions such as extraction solvent type,solid-liquid ratio,ultrasonic time,and settling time on the recovery of MNPs were investigated.The results showed that the extraction of MNPs from sediment by distilled water could effectively eliminate the high background signal interference introduced by the extractant under the conditions of solid-liquid ratio of 1∶400(g∶mL),ultrasonic extraction time of 1 h and settling time of 3 h.The detection limits for particle size of Ag-NPs,Zn-NPs,Ce-NPs and Ti-NPs in sediments were 31,35,26 and 85 nm,respectively,while the detection limits of particle concentrations were 1.21×104,1.90×104,5.26×107 and 1.48×107 particles/g,respectively.The spiking recoveries of Ag-NPs,Zn-NPs,Ce-NPs and Ti-NPs in sediments were 62.1％-108.7％,with relative standard deviations below 10％.This method could rapidly,accurately and simultaneously determine the concentration and particle size distribution of various MNPs in sediments,and was successfully applied to analysis of Ag-NPs,Zn-NPs,Ce-NPs,and Ti-NPs in authentic marine sediments.

At present,the drug substitutes represented by new psychoactive substances are gradually be-coming popular,leading to an increasing demand for identifying novel drugs with unknown structures in drug investigation.Nuclear magnetic resonance(NMR)spectroscopy is an important tool for ana-lyzing molecular structures.In the absence of standard substances,quantitative NMR(qNMR)can un-dertake the quantitative analysis of target substances in complex mixtures and has unique advantages in the research of new drugs and their precursor drugs.Due to the limitations of the site and mainte-nance costs,as well as relatively complex operation,high-field superconducting NMR is less com-monly applied in drug research.The desktop low-field NMR developed in recent years provides a new alternative solution.Due to the use of permanent magnets,its size is reduced,and the operation and maintenance costs are lowered.It has been widely used in various research fields.This article reviews the development of low-field NMR technology,summarizes the application of desktop low-field NMR in screening and identification of suspicious substances,rapid content determination,analysis of drug manufacturing processes and synthetic routes,and correlation traceability.It also looks forward to the prospects and development directions of this technology in drug research,aiming to provide a reference for researchers who work in analytical chemistry and drug research.
