Objective To analyze the characteristics of real-world adverse drug events(ADEs)of trabectedin based on the FDA Adverse Event Reporting System(FAERS)database in order to provide references for clinical drug safety management.Methods A total of 1 349 trabectedin-related reports were extracted from the FAERS database from Q1 2007 to Q4 2024.Using the MedDRA coding classification system for system organ class(SOC)and preferred term(PT),signal detection was performed through 4 proportional imbalance methods,including reporting odds ratio(ROR)and proportional reporting ratio(PRR).Subgroup analyses by gender,age,and temporal trends were also conducted.Results Hematological and lymphatic system disorders and hepatobiliary system disorders were the primary SOCs involved.High-frequency PTs included neutropenia(123 cases)and anemia(117 cases).Eight potential ADEs that have not been listed in the drug product instruction were identified.The median onset time of ADEs was 21 d,showing an early failure pattern,with differences observed by gender(females more prone to hematological toxicity)and age(elderly more susceptible to febrile neutropenia).Conclusion Trabectedin requires close attention to hematological toxicity,hepatotoxicity,and newly identified multi-system potential risks.Clinically,monitoring should be strengthened based on time windows and population characteristics to optimize drug regimens.Countermeasure It is recommended to strengthen the full cycle monitoring of anti-tumor drugs,standardize the reporting of adverse reactions,and establish a multi-departmental collaborative research platform.

Objective To explore the mechanism of Jiawei Jisheng Shenqi Decoction in improving the hypoxic microenvironment and antagonizing liver cirrhosis.Methods In vivo experiments were conducted using a rat model of carbon tetrachloride(CCL4)-induced liver cirrhosis.Rats were divided into normal,model,colchicine,JWJSSQ low-dose,JWJSSQ medium-dose,and JWJSSQ high-dose group.Pathological changes in liver tissues in each group were examined by hematoxylin and eosin(HE)and Masson staining,changes in serum liver function were detected using test kits,levels of hyaluronic acid(HA),laminin(LN),procollagen Ⅲ(PC Ⅲ),and collagen typeⅣ(COL4)were detected by enzyme-linked immunosorbent assay(ELISA),and protein expression levels of hypoxia-inducible factor-1α(HIF-1α),Notch1,Jagged1,and α-smooth muscle actin(α-SMA)were detected by Western blot.In vitro experiments were conducted in HSC-T6 cells,and the optimal concentration of CoCl2(100 μ mol/L,200μmol/L,400 μmol/L,600 μmol/L and 800 μmol/L)in the cultured cells and the optimal concentration of drug-containing serum(5％,10％,15％,20％)were determined by Cell Counting Kit-8(CCK-8)assay.The migration ability of cells in each group was detected by scratch testing,and changes in the apoptosis rates were determined by flow cytometry.Protein expression levels of HIF-1α,Notch1,Jagged1,α-SMA,matrix metallopeptidase 9(MMP9),and tissue inhibitor of metalloproteinases 1(TIMP-1)were detected by Western blot.Results In the in vivo experiments,liver swelling,inflammatory cell infiltration,collagen deposition,and the appearance of pseudolobules were significantly increased in the model group compared with those in the normal group.Serum levels of alanine aminotransferase(ALT),aspartate aminotransferase(AST),HA,LN,PCⅢ,and COL4 were significantly increased and albumin(ALB)was significantly decreased in the model group,while liver levels of HIF-1α,Notch1,Jagged1,and α-SMA proteins were significantly increased(P＜0.01).Liver swelling,inflammatory cell infiltration,and collagen deposition were significantly reduced in each treatment group compared with those in the model group,and the degree of fibrosis was reduced.Serum ALT,AST,HA,LN,PCⅢ,and COL4 were significantly decreased and ALB was significantly increased,while liver levels of HIF-1α,Notch1,Jagged1,and α-SMA proteins were also significantly decreased to varying degrees(P＜0.05).In the in vitro experiments,hypoxia promoted HSC-T6 migration and reduced apoptosis,increased the protein expression levels of HIF-1α,Notch1,Jagged1,α-SMA,and TIMP-1,and reduced the expression levels of MMP9(P＜0.01).Serum containing Jiawei Jisheng Shenqi Decoction inhibited HSC-T6 migration,promoted HSC-T6 apoptosis,lowered the expression of HIF-1α,Notch1,Jagged1,α-SMA,and TIMP-1 proteins,and enhanced the expression of MMP9 protein(P＜0.01).The inhibitory effect of Jiawei Jisheng Shenqi on HSC-T6 cell activation was reversed by the HIF-1α agonist dimethyloxalylglycine.Conclusions Jiawei Jisheng Shenqi Decoction can improve the hypoxic microenvironment via the HIF-1α/Notch pathway,thereby exerting an anti-liver cirrhosis effect.

【Objective】 To explore the diagnostic value of platelet long non-coding RNA (lncRNA) as a biomarker for early screening of lung adenocarcinoma (LUAD). 【Methods】 The GSE183635 and GSE89843 datasets, which contained the platelet transcriptome of LUAD and healthy controls, were used for differential analysis, and the intersection of the differentially expressed lncRNA(DElncRNA) of the two datasets was taken. The expression levels of DElncRNA in LUAD tissues and normal control tissues were analyzed using GEPIA2. The expression levels of LINC01088 in platelets of 51 healthy controls and 54 LUAD patients were detected by quantitative Real-time PCR (qRT-PCR), and the diagnostic ability of each index was evaluated by ROC curve. 【Results】 8 DElncRNAs and 1 265 DElncRNAs were obtained from GSE183635 and GSE89843 datasets, respectively. The key DElncRNA LINC01088 was selected after intersection. GEPIA2 analysis showed that the expression level of LINC01088 in LUAD tissues was lower than that in normal lung tissues (P<0.05). Platelet LINC01088 was significantly downregulated in patients with LUAD and early-stage LUAD than in healthy controls(P<0.001). The area under the curve (AUC) of platelet LINC01088 in the diagnosis of LUAD was 0.755, the sensitivity was 81.1%, and the specificity was 67.9%. The AUC for early LUAD diagnosis was 0.727, the sensitivity was 80.0%, and the specificity was 67.9%. The AUC of the combined diagnostic model composed of platelet LINC01088 and carcinoembryonic antigen (CEA) for LUAD diagnosis was 0.807, the sensitivity was 89.2%, and the specificity was 71.4%. The AUC for early LUAD was 0.770, the sensitivity was 86.7%, and the specificity was 71.4%. The combined diagnostic model of platelet LINC01088 and CEA was superior to CEA in the diagnosis of LUAD and early LUAD (Z=-2.288, -2.34, both P<0.05). 【Conclusion】 LINC01088 is down-regulated in platelets of LUAD patients. Platelet LINC01088 may be a biomarker for early screening and diagnosis of LUAD.

Objective:To evaluate the consistency between bioelectrical impedance analysis (BIA) and dual-energy X-ray absorptiometry (DXA) in the measurement of body composition in children aged 6-17 years in China.Methods:Fat-free mass, fat mass and fat mass percentage were measured by both BIA and DXA in 1 161 children. t-test or Wilcoxon paired test was used to evaluate the different outcome of the two methods. The correlation and consistency between the methods were evaluated by Spearman correlation coefficients ( r) and Bland-Altman analysis. Results:Body compositions measured by BIA was positively correlated with those measured by DXA (fat mass r=0.95, fat-free mass r=0.98, fat mass percentage r=0.86, all P<0.05). Comparing with DXA, BIA underestimate children's fat mass [the mean difference is -3.15 kg, and the SD is 2.35 kg, 95% limits of agreement (LoA): -7.74-1.45 kg] and fat mass percentage (the mean difference is -8.45%, and the SD is 4.63%, 95% LoA: -17.53%-0.64%). Conclusions:Body compositions measured by BIA was highly positively correlated with those measured by DXA. BIA has certain application value in the measurement of body fat mass and fat-free mass of children aged 6-17 years.

With the population aging, the prevalence rate of cardiovascular diseases in China continues to rise, among which, the mortality rate of aortic diseases is high, the treatment is difficult, and the risk is high. In recent years, the surgical treatment of aortic diseases in China has developed rapidly, and the overall scale has been increasing. This paper introduces the current status of treatment of aortic diseases in China, analyzes the medical quality of endovascular surgery and open surgery, including the number of operations, patient characteristics, mortality, readmission rate and other indicators, and compares the differences among different regions. In addition, advances in the treatment of aortic disease are discussed, including surgical methods, evaluation of effectiveness, and application of new technologies. Overall, China has made some progress in the treatment of aortic diseases, but it still faces the challenge of uneven distribution of medical resources and improvement of medical quality.

Objective:To compare the effect of self-radiopaque markers guiding physician-modified fenestration, chimney technique and hybrid Ⅳb technique on reconstruction of left subclavian artery (LSA) in endovascular treatment of aortic dissection (TEVAR).Methods:The clinical and follow-up data of 312 TEVAR patients treated with LSA blood supply reconstruction technology from Jan 2016 to Dec 2019 at Fuwai hospital were retrospectively analyzed.Results:There were 35 patients in the hybrid Ⅳb technique group, 93 in the chimney technique group, and 184 in the in vitro fenestration group. The follow-up period ranged from 12 to 24 months. No artificial blood vessel and stent occlusion occurred in all patients during follow-up, and the LSA blood flow was unobstructed. A total of 19 patients had endoleak by the last follow-up, and there was no statistical difference between the three groups. Eleven patients underwent reintervention surgery, all were from chimney technique group and in vitro fenestration group, with no statistical difference ( P>0.05). Severe complications occurred in 28 patients during hospitalization, and the incidence of complications was the highest in the hybrid Ⅳb technique group ( P<0.01). During follow-up, 4 patients died in the bypass group, 6 died in the external window group, and 8 died in the chimney group, with no significant difference ( P>0.05). Conclusions:The safety and efficacy of the left subclavian artery flow reconstruction by in vitro fenestration and chimney technique were similar. The occurrences of early complications were lower than that of the hybrid Ⅳb technique, but the reintervention rate of endoleak was higher.

Objective To analyze the clinical characteristics and factors influencing adverse treatment outcomes in elderly patients with multidrug-resistant pulmonary tuberculosis (MDR-TB) to guide the clinical diagnosis and treatment of elderly MDR-TB patients. Methods Clinical data of elderly patients with multidrug-resistant pulmonary tuberculosis initially treated at Beijing Chest Hospital from 2008 to 2023 were retrospectively collected. Complications/comorbidities, adverse drug reactions, drug resistance during initial treatment, and retreatment were statistically described. Factors influencing adverse treatment outcomes were analyzed using the chi-square test and logistic regression analysis. Results A total of 238 elderly patients with MDR-TB were collected, of which 152 (63.9%) had adverse drug reactions, 184 (77.3%) were retreated MDR-TB, 27 (11.3%) were extensively drug-resistant tuberculosis (XDR-TB), 41 were cured, 6 completed treatment, 39 failed treatment, 6 died, 107 lost to follow-up, 31 could not be evaluated, 8 did not finish treatment, and the treatment success rate was 20.4% (47/230). The adverse outcome of treatment accounted for 79.6% (183/230). Univariate analysis showed that differences in age groups, the occurrence of drug adverse reactions, and patient sources had a statistically significant impact on treatment outcomes (P<0.05). Logistic regression analysis was performed using good and adverse treatment outcomes as dependent variables for the three factors, which showed that being aged 70 and above, the occurrence of drug adverse reactions during treatment, and being a non-local patient were factors influencing adverse treatment outcomes [OR (95%CI): 2.507 (1.027-6.121), 3.253 (1.635-6.473), 2.563 (1.285-5.111), respectively]. Conclusions Elderly patients with MDR-TB exhibit a high prevalence of complications/comorbidities, a high incidence of drug adverse reactions, and unfavorable treatment outcomes. Out-of-town medical treatment, advanced age, and experiencing drug adverse reactions are risk factors for adverse treatment outcomes.

CCAAT enhancer binding protein β (C/EBPβ), as a nuclear transcription factor necessary for the development of liver, airway epithelium, and adipose tissue, plays a vital role in physiological processes related to cell proliferation, apoptosis, and differentiation. However, the up-regulation of C/EBPβ activates signal pathways related to inflammatory response, epithelial-mesenchymal transition, cell proliferation and invasion, immune response, and angiogenesis by regulating a series of downstream genes transcription promotes the development of lung diseases. Therefore, targeting C/EBPβ may be a potential treatment strategy for lung diseases. This paper summarizes the regulatory effects of C/EBPβ and related signaling pathways in lung infection, asthma, chronic obstructive pulmonary disease, lung injury, pulmonary fibrosis, and lung cancer to provide a theoretical basis for the precision medicine of lung diseases.

Objective:To evaluate the safety and feasibility of the in-situ needle fenestration combined with the in vitro physician modified fenestration technique to reconstruct supra-aortic branches during thoracic endovascular aortic repair (TEVAR) for aortic arch lesions requiring landing at Z0 and Z1.Methods:From Nov 2017 to Dec 2019, eighteen patients who underwent both the in-situ needle fenestration and the in vitro physician modified fenestration techniques to extend the proximal landing zone to Z0 and Z1 during TEVAR were included in our study.Results:Sixteen patients underwent in vitro physician modified fenestration ,two patients underwent in vitro physician modified fenestration to reconstruct both the left common carotid artery and the innominate artery. All eighteen patients received in-situ needle fenestration to preserve the left subclavian artery. Supra aortic branches were preserved in all patients (38/38, 100%). There was no Type Ⅰ endoleak. Type Ⅱ endoleak was found in four paitnets (4/18). Type Ⅲ endoleak occurred in one patient (1/18). Type Ⅳ endoleak in four patients (4/18). Type Ⅲ endoleak needed open aortic arch repair 6 months later. The median follow-up time was 12 months. One (1/18) died in 12 months and the other patients were doing well.Conclusions:The joint application of the in-situ needle fenestration and the in vitro physician modified fenestration to reconstruct supra-aortic branches during TEVAR for aortic arch pathologies requiring landing at Z0 and Z1 was satisfactory.
