OBJECTIVE To develope a predictive model for medication deviation risks during the hospital-to-home transition period in coronary heart disease （CHD） patients with initial treatment， aiming to assist medical staff in rapidly identifying high-risk groups for medication deviation. METHODS A total of 462 CHD patients with initial treatment from the Affiliated Hospital of North China University of Science and Technology （hereinafter referred to as “our hospital”） between January and July 2024 were enrolled. The patients were randomly divided into a modeling group and an internal validation group. The modeling group was further categorized into a medication deviation group and a non-medication deviation group based on whether medication deviations occurred. Similarly， 57 CHD patients with initial treatment from the cardiology department of our hospital between June and September 2025 were collected as an external validation group. Univariate analysis was used to screen predictive factors， followed by multivariate Logistic regression to construct the predictive model. Internal validation methods were employed to evaluate model performance， while external validation methods were used to test the model’s generalizability. RESULTS The 462 patients were divided into a modeling group （319 cases） and an internal validation group （143 cases）. In the modeling group， the medication deviation group （192 cases， 60.19%） and the non-medication deviation group （127 cases， 39.81%） were identified. Multivariate Logistic regression analysis revealed that age， medication type， medication adherence， and self-efficacy in rational medication use were predictive factors for medication deviations in CHD patients with initial treatment （ P ＜0.05）. The predictive model equation was logit P ＝ln[ P /（1－ P ） ] ＝1.321+1.732×age+4.091×medication type －4.360×medication adherence －3.081×self-efficacy in rational medication use. The model demonstrated good discrimination， with a Hosmer-Lemeshow goodness-of-fit test P -value of 0.439， an area under the receiver operating characteristic curve （AUC） of 0.870， sensitivity of 0.970， and specificity of 0.607. A risk nomogram with a total score of 350 points and a cutoff value of 110 points was plotted. The internal validation group showed an AUC o f 0.787 and a prediction accuracy of 77.6%， while the external validation group exhibited an AUC of 0.802 and a prediction accuracy of 73.7%. CONCLUSIONS This study successfully developed a predictive model for medication deviation risks during the hospital-to-home transition period in CHD patients with initial treatment. The model demonstrates excellent discrimination and predictive accuracy， effectively identifying high-risk populations for medication deviations. Age （＞70 years）， number of drug types≥5， poor medication adherence， and poor self-efficacy in rational medication use are independent risk factors for medication deviations.

AIM To investigate the impact of varying dosages of Supplemented Wendan Decoction on the PI3K/Akt/FOXO1 glycolipid metabolic pathway in 3T3-L1 adipocytes.METHODS The CCK-8 assay was used to determine the concentration of Supplemented Wendan Decoction-medicated serum.The mature adipocytes differentiated from 3T3-L1 preadipocytes after induction were further divided into the blank control group,the model group,the rosiglitazone group(10 mg/L),and the Supplemented Wendan Decoction groups(5％,10％,and 20％),followed by the sample collections after 48 hours of treatment.Oil red O staining quantified lipid accumulation in 3T3-L1 adipocytes;extracellular glucose levels were measured using glucose oxidase(GOD)assay;RT-qPCR analyzed mRNA expressions of IRS-1,PI3K,Akt,GLUT4,IL-6,TNF-α and IL-1β;Western blot assessed protein expressions of INSR,IRS-1,PI3K-p85,Akt,FOXO1 and GLUT4.RESULTS No significant changes in cell viability(P＞0.05)were observed in 3T3-L1 preadipocytes exposed to serum containing supplemented Wendan Decoction at different concentrations for 24,48,or 72 hours.The 3T3-L1 preadipocytes held the capacity to differentiate into mature adipocytes within a 14-day induction period.Compared to the model group,all supplemented Wendan Decoction groups exhibited reduced lipid accumulation in adipocytes and downregulated mRNA expression of IRS-1,IL-6,TNF-α and IL-1β(P＜0.01);the low-dose group demonstrated increased mRNA expressions of PI3K and GLUT4(P＜0.05,P＜0.01),alongside elevated protein expressions of INSR,IRS-1,PI3K-p85,Akt and GLUT4(P＜0.05,P＜0.01);the medium-dose group showed enhanced GLUT4 mRNA expression,and upregulated protein expressions of INSR and FOXO1(P＜0.01).After 24 hours intervention,the high-dose Supplemented Wendan Decoction group exhibited increased glucose consumption in adipocytes(P＜0.01),and elevated protein expression of INSR,Akt and FOXO1(P＜0.05,P＜0.01).CONCLUSION Supplemented Wendan Decoction reduces lipid accumulation in adipocytes,regulates glucose and lipid metabolism,and promotes metabolic homeostasis through PI3K/Akt/FOXO1 signaling pathway.

Objective To investigate the clinical efficacy and safety of facilitated percutaneous coronary intervention(PCI)with half-dose recombinant staphylokinase(r-SAK)in patients with ST-segment elevation myocardial infarction(STEMI)who are expected to undergo PCI within 120 minutes.Methods From October 2021 to August 2022,a total of 200 STEMI patients in eight centers were included and randomly assigned in a 1﹕1 ratio to either r-SAK group or control group.Patients received loading doses of aspirin and ticagrelor and intravenous heparin and were randomized to receive an intravenous bolus of either 5 mg r-SAK or normal saline prior to PCI.The outcomes were set as ST-segment resolution(STR)at 60-90 minutes after PCI,the proportion and transition of pathological Q waves on the 5th day after PCI,and the proportion of high-sensitivity cardiac troponin T(hs-cTnT)peaking within 12 hours of onset.The safety outcome was major bleeding events defined as Bleeding Academic Research Consortium(BARC)≥type 3 bleeding during hospitalization.Results Compared with the control group,the r-SAK group had a higher proportion of STR≥70%within 60-90 minutes after PCI(58.3%vs.40.3%,P=0.009);a lower proportion of pathological Q waves(59.1%vs.74.1%,P=0.040);a lower rate of Q wave progression(14.8%vs.43.2%,P＜0.001);a higher rate of Q wave disappearance(12.5%vs.3.7%,P=0.027);and a higher proportion of hs-cTnT peaking within 12 hours of symptom onset[31/40(77.5%)vs.17/33(51.5%),P=0.027].Regarding the safety outcome,no significant difference in BARC≥type 3 bleeding was found between the two groups during hospitalization(P＞0.05).Conclusions For STEMI patients who were expected to undergo primary PCI within 120 minutes of symptom onset,the facilitated PCI with half-dose r-SAK significantly increased the proportion of STR≥70%at 60-90 minutes after PCI,reduced the formation of pathological Q waves,and shortened the time to peak hs-cTnT,without increasing the risk of bleeding,which should be an alternative reperfusion strategy worthy of further study.

BACKGROUND:In recent years,the application of exosomes of periodontal ligament stem cells in periodontal tissue regeneration engineering has been widely studied,but the effect of exosomes on periodontal ligament stem cells derived from inflammatory environment is still unclear.OBJECTIVE:To investigate the effects of exosomes secreted by periodontal ligament stem cells from healthy and inflammatory environments on the proliferation and differentiation of periodontal ligament stem cells from inflammatory environments.METHODS:Human periodontal ligament stem cells from healthy and inflammatory tissues were isolated and cultured by enzyme digestion method.Exosomes were extracted from two kinds of periodontal ligament stem cells using ultracentrifugation.Passage 3 periodontal ligament stem cells derived from inflammatory tissue were selected and cultured in three groups.Cells in the blank group were cultured routinely.The healthy exosome group was added with exosomes secreted by peripheral ligament stem cells derived from healthy tissue.The inflammatory exosome group was added with exosomes secreted by human periodontal ligament stem cells derived from inflammatory tissue.Cell proliferation and cloning were detected.The expression of alkaline phosphatase,the formation of mineralized nodules,and the expression of mRNA and protein of genes related to osteogenesis were detected under osteogenic differentiation.RESULTS AND CONCLUSION:(1) CCK-8 assay and clonal formation test showed that compared with the blank group,two kinds of exosomes could promote the proliferation and colony formation of periodontal ligament stem cells from inflammatory tissue (P<0.05),and the effect of the healthy exosome group was stronger than that of the inflammatory exosome group (P<0.05).(2) Alkaline phosphatase and alizarin red staining showed that compared with the blank group,the two kinds of exosomes could promote the expression of alkaline phosphatase and the formation of mineralized nodules in periodontal ligament stem cells from inflammatory tissue,and the promoting effect of the healthy exosome group was stronger than that of the inflammatory exosome group.RT-PCR and western blot assay showed that compared with the blank group,the two kinds of exosomes could promote the expression of alkaline phosphatase,RUNX2,and type Ⅰ collagen mRNA and protein in periodontal ligament stem cells from inflammatory tissue (P<0.05).The promoting effect of the healthy exosome group was stronger than that of the inflammatory exosome group (P<0.05).(3) The results showed that exosomes secreted by human periodontal ligament stem cells could promote the proliferation and osteogenic differentiation of periodontal ligament stem cells derived from inflammatory environments,and the promoting effect of exosomes secreted by human periodontal ligament stem cells derived from healthy tissues was better than that from human periodontal ligament stem cells derived from inflammatory tissues.

Iodine speciations in aquatic environments are affected by dissolved oxygen,redox potential,microbial activity,organic matter decomposition,light reaction,etc.Accurate quantification of iodine speciation can not only help to understand the geochemical cycle of iodine,but also help to trace and study environmental processes.Based on the combination of ion chromatography(IC)and inductively coupled plasma mass spectrometry(ICP-MS),a rapid and sensitive method was established for determining the speciations of iodine in environmental water samples including seawater,river water,lake water,rainwater,groundwater,etc.The results presented here showed that IO3?and I?in seawater were quickly separated and measured within 120 s when using guard column AG22 and 8 mmol/L(NH4)2CO3 as the mobile phase.While for lake water,river water and precipitation samples with high soluble organically bond iodine(SOI),an AS22 separation column(250 mm×4 mm)connected with a guard column and using 50 mmol/L(NH4)2CO3 as mobile phase could effectively separate unknown SOI from IO3? to achieve accurate quantification of IO3?.For accurate correction of iodine measurement signal fluctuations,133Cs was directly added to the(NH4)2CO3 mobile phase as an internal standard.The SOI content was calculated by the total iodine concentrations minus the sum of IO3?and I?.The precision of the established iodine speciation analytical method was better than 3.5%,and the standard addition experiment showed that the analytical method was accurate.When the injection volume was 25 μL,the detection limits were 0.011?0.025 μg/L for IO3? and 0.023?0.031 μg/L for I?,respectively.The method was successfully used to analyze IO3?,SOI and I? in environmental water samples,such as seawater,river water,rainwater and groundwater.

The cycling of iodine in the atmosphere and ocean plays a critical role in climate and environmental change.Ice cores and tree rings,as ideal climate archives,can provide essential data for paleoclimate reconstruction through accurate iodine analysis.However,iodine concentrations in ice core samples are as low as 0.01 μg/L,and as low as 0.01 μg/g in tree rings.Most currently reported analytical methods face challenges in accurately quantifying such low levels.In this study,a highly sensitive analytical method for trace iodine in environmental samples was developed based on inductively coupled plasma mass spectrometry(ICP-MS),incorporating a collision/reaction cell under the optimized collision/reaction gas conditions.Collision/reaction cell mode was employed to evaluate potential interferences in determination of trace iodine by ICP-MS.The results indicated that peak tailing from adjacent mass-to-charge ratios and polyatomic ion interferences could be considered negligible.However,residual iodine in ultrapure water constituted the major source of background,highlighting the need for strict control of sample pretreatment and procedural blanks in trace-level iodine analysis.By utilizing collision focusing effect of helium,the measurement sensitivity of iodine was enhanced to 3.5×105 cps(counts per second)/(μg/L),and the detection limit was reduced to 0.002 μg/L.The developed method exhibited a deviation of less than 2.3%in measurement of low-concentration standard solutions,indicating good accuracy.For actual samples and blanks,the precision of repeated measurements within 2 h was better than 1.6%,demonstrating excellent repeatability.No significant memory effect was observed during the measurements.The established method was successfully applied to determination of trace iodine in ice cores,tree rings,and other environmental samples,providing a robust technical foundation for investigating the role of iodine in climate and environmental change.

Objective·To explore the diagnostic and treatment methods for patients with cystic fibrosis(CF)complicated by allergic bronchopulmonary aspergillosis(ABPA),and to enhance clinicians'understanding of these two diseases.Methods·A retrospectively analysis was conducted on the clinical data of 5 patients with CF complicated by ABPA admitted to the Department of Respiratory Medicine,Shanghai Children's Hospital,Shanghai Jiao Tong University School of Medicine,from July 2023 to August 2024.A literature search was performed in PubMed,Web of Science,Cochrane Library,and CNKI for studies published in the past 10 years regarding the co-existence of these diseases.Clinical manifestations,treatment courses,and current epidemiological research were summarized and analyzed.Results·Common symptoms of patients with CF complicated by ABPA included aggravated cough and expectoration,wheezing,fever,and dyspnea.Whole-exome aequencing indicated mutations in the cystic fibrosis transmembrane conductance regulator(CFTR)gene,and an increase in the concentration of chloride ions in sweat.The levels of total serum immunoglobulin E(IgE)and Aspergillus fumigatus-specific IgE increased,and chest computed tomography(CT)showed bronchiectasis and mucus plugging.CF complicated by ABPA is often missed or misdiagnosed for asthma.In China,ABPA is often diagnosed before CF,whereas in Caucasian populations CF is typically diagnosed first.Initial treatment usually involves long-term oral administration of antifungal drugs such as voriconazole combined with glucocorticoids such as prednisone.For patients with frequent relapses or severe side effects,alternative antifungal agents or omalizumab therapy may be considered.Co-infection with Pseudomonas aeruginosa is common,often requiring intravenous antibiotics such as cefoperazone-sulbactam.Current epidemiological research focuses mainly on clinical characteristics,treatment regimens,and novel diagnostic methods.Conclusion·ABPA and CF have overlapping symptoms.Accurate diagnosis of CF complicated by ABPA requires genetic testing,sweat chloride measurement,chest CT,and serological tests.The coexistence of these diseases often leads to missed,delayed,or incorrect diagnosis,increasing patient burden.Present epidemiological studies mainly address clinical characteristics with a lack of targeted clinical drug trials for this patient population.
