Background Injury poses a serious threat to human health. As global warming continues to intensify, there is an urgent need to explore the impact of temperature changes on injury deaths. However limited research has focused on this issue. Objective To investigate the relationship between daily mean temperature change (Tm) and injury death, as well as to estimate the associated future death burden in Hunan Province. Methods We employed an individual-level, time-stratified case-crossing design to establish a conditional logistic regression model to analyze the exposure-response relationship between daily mean temperature change and injury death in Hunan Province from 2013 to 2018. Consequently, we conducted subgroup analysis of gender, age group, and injury type. Finally, we estimated the excess burden of injury death attributable to temperature changes under a sustainable development path [low emission scenario (SSP1-2.6)], regional competition path [high emission scenario (SSP3-7.0)], or fossil fuel development path [very high emission scenario (SSP5-8.5)]. Results The study collected

Wilson disease is a copper metabolism disorder caused by mutations in the ATP7B gene, which encodes a copper-transporting ATPase β, and can result in multisystem damage. The kidneys are the third most commonly affected organs after the liver and brain. In recent years, numerous diagnostic and treatment guidelines for Wilson disease have emerged. However, most of these focus primarily on hepatic and neurological manifestations and their management, with limited coverage of renal involvement. The high incidence, low awareness, and lack of clinical specificity of Wilson disease-related renal damage (WDRD) have made early detection and intervention particularly challenging in clinical practice. To further optimize the treatment of patients with WDRD, improve clinical diagnosis and management, and enhance patients' quality of life, the Neurology Committee of the Chinese Association of Integrative Medicine, in April 2024, initiated a revision of the first expert consensus on the integrated diagnosis, treatment, and management of WDRD. This effort brought together experts in hepatology, encephalopathy (neurology), and nephrology from many tertiary-level grade A hospitals and research institutions across China. Through comprehensive literature review and integration of frontline clinical experience, the expert group jointly developed Chinese Expert Consensus on Integrated Chinese and Western Medicine Management of Wilson Disease-related Renal Damage (hereinafter referred to as the "Consensus"). This article provides a detailed interpretation of the Consensus in terms of diagnostic criteria, traditional Chinese medicine (TCM) syndrome differentiation and treatment classification, and comprehensive disease management, aiming to better guide clinical application. Regarding diagnostic criteria, the Consensus integrates the latest standards in China and abroad, highlights the importance of biochemical diagnosis, and compensates for the limitations of genetic testing. In the area of TCM syndrome differentiation and treatment, the Consensus refines four major syndrome types, introduces a newly defined syndrome, i.e., phlegm, blood stasis, and heat accumulation, and elaborates on treatment principles, prescriptions, and clinical modification rules for each syndrome. For comprehensive disease management, the Consensus emphasizes multi-dimensional intervention strategies, including diet, exercise, emotional regulation, medication, and medical care, with the goal of maximally controlling the progression of renal dysfunction and helping patients achieve a better quality of life.

Effective annotation of in vivo drug metabolites using liquid chromatography-mass spectrometry (LC-MS) remains a formidable challenge. Herein, a metabolic reaction-based molecular networking (MRMN) strategy is introduced, which enables the "one-pot" discovery of prototype drugs and their metabolites. MRMN constructs networks by matching metabolic reactions and evaluating MS2 spectral similarity, incorporating innovations and improvements in feature degradation of MS2 spectra, exclusion of endogenous interference, and recognition of redundant nodes. A minimum 75% correlation between structural similarity and MS2 similarity of neighboring metabolites was ensured, mitigating false negatives due to spectral feature degradation. At least 79% of nodes, 49% of edges, and 97% of subnetworks were reduced by an exclusion strategy of endogenous ions compared to the Global Natural Products Social Molecular Networking (GNPS) platform. Furthermore, an approach of redundant ions identification was refined, achieving a 10%-40% recognition rate across different samples. The effectiveness of MRMN was validated through a single compound, plant extract, and mixtures of multiple plant extracts. Notably, MRMN is freely accessible online at https://yaolab.network, broadening its applications.

Five novel nor-eremophilane-type sesquiterpenoids, peniroqueforins E-H and J (1-4 and 7), two new eremophilane-type sesquiterpenoids, peniroqueforins I and K (5 and 8), and a new eudesmane-type sesquiterpenoid, peniroqueforin L (9), along with four known compounds (6 and 10-12), were isolated and characterized from fungus Penicillium roqueforti (P. roqueforti). The structures and absolute configurations of these compounds were determined through comprehensive spectroscopic analyses, electronic circular dichroism (ECD) data analyses, and single-crystal X-ray diffraction methods. The anti-multi-drug resistance (MDR) cancer activity of these compounds was evaluated using SW620/Ad300 cells. Notably, the half maximal inhibitory concentration (IC50) value of paclitaxel (PTX) combined with 1 in SW620/Ad300 cells was 50.36 nmol·L-1, which was 65-fold more potent than PTX alone (IC50 3.26 μmol·L-1). Subsequent molecular docking studies revealed an affinity between compound 1 and P-glycoprotein (P-gp), suggesting that this nor-eremophilane-type sesquiterpenoid (1) could serve as a potential lead for MDR reversal in cancer cells through P-gp inhibition.

Objective:To investigate the effect of bone mesenchymal stem cells derived exosomes (BMSC-Exo) on improving hippocampal microangiogenesis, energy metabolism, and behaviors in depression mouse models.Methods:(1) Mouse bone marrow mesenchymal stem cells were isolated and cultured to extract BMSC-Exo; BMSC-Exo morphology was observed by transmission electron microscopy, BMSC-Exo particle diameter ranges were determined by Zetaview analyzer, and expressions of CD9 and CD63 in BMSC-Exo were detected by Western blotting. (2) Depression models were established in 2 mice by chronic unforeseeable mild stress (CUMS); 24 h after stereotaxic injection of phosphate buffer solution (PBS) or DiR labeled BMSC-Exo, BMSC-Exo uptake was detected by in vivo imaging system. (3) Thirty-six mice were randomly divided into control group, model group and BMSC-Exo group ( n=12); CUMS was used to establish depression models in the latter 2 groups; brain stereotaxic injection of 1 μL BMSC-Exo was given to mice in the BMSC-Exo group after modeling, and same amount of PBS was given to the control group; behaviors were observed by forced swimming test (FST), tail suspension test (TST) and open field test (OFT); hippocampal microvascular length and number were detected by alkaline phosphatase staining; energy metabolism in the hippocampus was detected by micro positron emission tomography/computed tomography (mPET/CT); glucose transporter 1 (GLUT1) expression in the hippocampus was detected by Western blotting. Results:(1) BMSC-Exo had a typical disk-like vesicle-like structure with particle size of (100.5±1.4) nm; Western blotting confirmed that CD9 and CD63 expressed in BMSC-Exo. (2) In vivo imaging showed no fluorescence in the brain and liver after PBS injection, but obvious local fluorescence after BMSC-Exo injection. (3) Compared with the control group, the model group and BMSC-Exo group had significantly longer rest time in FST and TST and shorter movement distance and time in the central region of OFT ( P<0.05); compared with the model group, BMSC-Exo group had significantly shorter rest time in FST and TST and longer movement distance and time in the central region of OFT ( P<0.05). Compared with the control group, the model group and BMSC-Exo group had significantly decreased standard uptake value (SUV) of regions of interest, microvascular length and number, and GLUT1 expression in the hippocampus ( P<0.05); compared with the model group, the BMSC-Exo group had significantly higher SUV, microvascular length and number, and GLUT1 expression in the hippocampus ( P<0.05). Positive correlations were noted between hippocampal microvascular length and SUV and between microvascular number and SUV in the 3 groups ( r=0.540, P<0.001; r=0.600, P<0.001). Conclusion:BMSC-Exo could promote microangiogenesis energy metabolism in the hippocampus to improve depression-like behaviors in depression mouse models.

OBJECTIVE To optimize the ultrasound-assisted extraction-deep eutectic solvents technology of total flavonoids from Hypericum japonicum, evaluate its hypoglycemic activity in vitro, and analyze its chemical compositions preliminarily. METHODS The most suitable deep eutectic solvent for total flavonoids from H. japonicum was screened using the composition of hydrogen bond acceptor and donor, molar ratio, water content as factors, and the total flavonoid yield as the response value. Using liquid-solid ratio, ultrasonic power, ultrasonic temperature and ultrasonic time as factors, the yield of total flavonoids as response value, the extraction technology of total flavonoids from H. japonicum was optimized by single-factor experiments combined with Box-Behnken response surface method, and the optimum extraction technology was validated. Taking acarbose as the positive control, the inhibitory activities of total flavonoids from H. japonicum on α-amylase and α-glucosidase in vitro were determined. The chemical constituents of total flavonoids from H. japonicum were analyzed by UPLC combined with comparing the reference substances. RESULTS The most suitable deep eutectic solvent was choline chloride-oxalic acid (the molar ratio of 1∶1, the water content of 30%). The optimum extraction technology was as follows: the ratio of liquid-solid was 52∶1 (mL/g), the ultrasonic temperature was 54 ℃ , the ultrasonic power was 240 W, and the ultrasonic time was 42 min; the total extraction yield of total flavonoids from H. japonicum in 3 validation tests was (73.26±2.48) mg/g, the relative error of which with the theoretical value (73.48 mg/g) was -0.30%. The total flavonoids from H. japonicum could inhibit α-amylase and α-glucosidase with IC50 values of 0.73 and 0.44 mg/mL, respectively, which were higher than those of acarbose (0.23 and 0.15 mg/mL). UPLC analysis showed that the total flavonoids from H. japonicum contained isoquercetin, quercitrin, quercetin-7-O-α-L-rhamnoside and quercetin. CONCLUSIONS The optimized extraction technology of total flavonoids from H. japonicum is stable and feasible, and the extract has certain hypoglycemic activity in vitro and contains isoquercetin, quercitrin and quercetin-7-O-α-L-rhamnoside, etc.

OBJECTIVE To provide a reference for the adjustment of antibacterial drug regimens, identification of adverse reactions, and personalized pharmaceutical care for patients with bullous pemphigoid and pulmonary aspergillosis combined with disseminated Nocardia farcinica infection. METHODS Clinical pharmacists participated in the entire treatment process of a patient with bullous pemphigoid and pulmonary aspergillosis combined with disseminated N. farcinica infection. Evidence-based medicine was used to assist in the selection of an initial combined drug regimen against nocardiosis, and timely communication with the microbiology laboratory to provide early antimicrobial susceptibility data. When the patient exhibited epilepsy, the suspected drugs were identified, and it was reminded that imipenem-cilastatin sodium could affect the efficacy of valproic acid. It was suggested to replace valproic acid with levetiracetam for anti-epileptic treatment and to discontinue imipenem-cilastatin sodium. During treatment, it was recommended to monitor the blood concentrations of voriconazole and linezolid, and assist in adjusting the dosage promptly based on the monitoring results. RESULTS The physicians accepted the recommendations of the clinical pharmacists. The patient’s condition improved, and they were discharged with medication. CONCLUSIONS Based on evidence-based medical evidence, antimicrobial susceptibility test results, and blood concentration monitoring data, clinical pharmacists assist clinicians in selecting a sensitive anti-infective regimen for the patient, identifying adverse reactions, adjusting the treatment regimen and providing full-course medication monitoring to ensure the safety and efficacy of clinical drug therapy.

Background:
Twenty-four-hour urinary free cortisol (UFC) measurement is the initial diagnostic test for Cushing’s syndrome (CS). We compared UFC determination by both direct and extraction immunoassays using Abbott Architect, Siemens Atellica Solution, and Beckman DxI800 with liquid chromatography-tandem mass spectrometry (LC-MS/MS). In addition, we evaluated the value of 24-hr UFC measured by six methods for diagnosing CS.
Methods:
Residual 24-hr urine samples of 94 CS and 246 non-CS patients were collected.A laboratory-developed LC-MS/MS method was used as reference. UFC was measured by direct assays (D) using Abbott, Siemens, and Beckman platforms and by extraction assays (E) using Siemens and Beckman platforms. Method was compared using Passing–Bablok regression and Bland–Altman plot analyses. Cut-off values for the six assays and corresponding sensitivities and specificities were calculated by ROC analysis.
Results:
Abbott-D, Beckman-E, Siemens-E, and Siemens-D showed strong correlations with LC-MS/MS (Spearman coefficient r = 0.965, 0.922, 0.922, and 0.897, respectively), while Beckman-D showed weaker correlation (r = 0.755). All immunoassays showed proportionally positive bias. The areas under the curve were 0.975 for Abbott-D, 0.972 for LCMS/MS, 0.966 for Siemens-E, 0.948 for Siemens-D, 0.955 for Beckman-E, and 0.877 for Beckman-D. The cut-off values varied significantly (154.8–1,321.5 nmol/24 hrs). Assay sensitivity and specificity ranged from 76.1% to 93.2% and from 93.0% to 97.1%, respectively.
Conclusions
Commercially available immunoassays for measuring UFC show different levels of analytical consistency compared to LC-MS/MS. Abbott-D, Siemens-E, and Beckman-E have high diagnostic accuracy for CS.
