Background: and Purpose Vertebrobasilar fusiform aneurysms (VBFAs) carry substantial morbidity and mortality, but optimal management for unruptured VBFAs remains unclear. We compared the safety and efficacy of conservative management (CM), stent-assisted coiling (SAC), and flow diverters (FDs) in patients with unruptured VBFAs, focusing on long-term prognosis. Methods: This study included data from a nationwide Chinese cohort of patients with vertebrobasilar dissecting aneurysms. Inverse probability of treatment weighting (IPTW) balanced confounders across groups. The primary outcome was poor prognosis (modified Rankin Scale score >2). Secondary outcomes included aneurysm rupture, ischemic stroke, compression symptoms, and VBFA-related deaths. Logistic regression estimated odds ratios (ORs) and 95% confidence intervals (CIs). Subgroup and sensitivity analyses were performed. Results: Among 1,115 patients with unruptured VBFAs, 838 (median age, 54 years; 655 men) were included. After IPTW, baseline characteristics were balanced. Median follow-up was 54 months. FD was associated with a lower risk of poor prognosis than CM (OR, 0.48 [95% CI, 0.30 to 0.77]; p=0.002), with no difference between CM and SAC. FD also reduced aneurysm rupture (OR, 0.20 [95% CI, 0.07 to 0.60]; p=0.004) and compression symptoms (OR, 0.30 [95% CI, 0.13 to 0.68]; p=0.004) versus CM. Time-to-event analyses further revealed significant differences in vertebral artery lesions and Type I–II VBFAs, whereas no significant differences were observed in basilar or vertebrobasilar junction lesions or in Type III–IV VBFAs. Conclusions Compared with CM, FD was associated with improved long-term outcomes in unruptured VBFAs, particularly in vertebral artery lesions and Type I–II VBFAs, although residual confounding cannot be excluded.

Objective To establish the fingerprints and predict the quality markers of Sanqi Shenfeng oral liquid based on fingerprint and network pharmacology.Methods The fingerprints of 12 batches of Sanqi Shenfeng oral liquid were established by using HPLC,and their peaks were identified and assigned.The candidate components were selected by multiple statistical analysis methods such as similarity evaluation,hierarchical cluster analysis,principal component analysis and orthogonal partial least squares discrimination analysis(OPLS-DA).The"component-target-pathway"network diagram was constructed by network pharmacology,and the quality markers of Sanqi Shenfeng oral liquid were predicted.Results The 13 common peaks were identified from the established fingerprint.Compared with the reference material,eight common peaks were identified as 3(tetrahydroxystilbene glucoside),5(sodium benzoate),6(lobetyolin),7(notoginsenoside Ri),9(ginsenoside Rgi),10(ginsenoside Re),12(10-hydroxy-2-decenoic acid),13(ginsenoside Rb1).The similarity of 12 batches of Sanqi Shenfeng oral liquid samples was higher than 0.997,and 12 batches of samples were grouped into two categories.OPLS-DA analysis showed that peaks 2,3,4,7,9,10,11,12 were the main signature components affecting the quality of Sanqi Shenfeng oral liquid.Network pharmacology predicted that lobetyolin,notoginsenoside R1,ginsenoside Rg1,ginsenoside Rb1,ginsenoside Re and 10-hydroxy-2-decenoic acid were potential Q-markers of Sanqi Shenfeng oral liquid.The traditional functions are performed through STAT3/AKT1-Drp1,HIF-1 and PI3K-AKT signaling pathway.Conclusion The established fingerprint has good reproducibility,stability and feasibility.The six components have great influence on the quality of Sanqi Shenfeng oral liquid,which are transferable and traceable,and are closely related to the efficacy.They can be used as potential quality markers to provide a scientific basis for the quality control and evaluation of Sanqi Shenfeng oral liquid.

Objective To discuss the value of the multi-parameter imaging of dual-energy computed tomography(DECT)combined with apparent diffusion coefficient(ADC)value of brain metastases in predicting lung adenocarcinoma with epidermal growth factor receptor(EGFR)gene mutation.Methods The DECT and MRI parameters of 90 patients with lung adenocarcinoma and brain metastases were collected.DECT parameters included normalized iodine concentrations in the arterial and venous phases(N1CA,NICV)and slope of the energy spectrum curves in the arterial and venous phases(kA,kv).The MRI parameters of brain metastases included ADC and relative ADC(rADC)of solid area,necrotic area,and peritumoral edema.Predictive model were constructed for EGFR gene mutation according to the parameters above.Results NICV,kv,ADC and rADC of solid area and peritumoral edema in the EGFR positive group were higher than those in the EGFR negative group,which had statistical significances(P＜0.05).Model1 and model2 were established by combining DECT or MRI parameters,while model3 was established by combining DECT and MRI parameters,which had the best predictive efficiency for EGFR gene mutation,with an area under the curve(AUC)of 0.846.Conclusion The predictive model combining DECT parameters with ADC value of brain metastases can improve the prediction efficiency of EGFR gene mutation in advanced lung adenocarcinoma.

Objective To explore the predictive value of serum procalcitonin(PCT),peripheral blood complement C3,C4 and lymphocyte subsets CD3+,CD4+and CD8+cells for plastic bronchitis(PB)in children with refractory Mycoplasma pneumoniae pneumonia(RMPP).Methods A total of 222 children with RMPP were selected and divided into the PB group(51 cases)and the non-PB group(171 cases)based on whether they were complicated with PB.The serum PCT level of the children at admission was detected by fluorescence immunoquantitative analyzer,and levels of complement C3 and C4 were detected by immunoturbidimetry.The proportions of CD3+,CD4+and CD8+T lymphocytes were detected by flow cytometry.Multivariate Logistic regression analysis was conducted to analyze influencing factors of PB in children with RMPP.Receiver operating characteristic(ROC)curve was used to analyze the predictive value of the indicators.Results The levels of PCT and CD8+T cells and the duration of fever were higher in the PB group than those in the non-PB group,while the levels of complement C3 and CD4+T cells were lower than those in the non-PB group(P＜0.05).Elevated levels of PCT and CD8+T cells were risk factors for the occurrence of PB in children with RMPP,while elevated levels of complement C3 and CD4+T cells were protective factors for the occurrence of PB in children with RMPP(P＜0.05).The AUCs of PCT,complement C3,the proportion of CD4+T cells and the proportion of CD8+T cells predicted separately were 0.763,0.802,0.788 and 0.802 respectively,and the AUC of combined prediction was 0.915.The AUCs of individual predictions were all lower than those of the combined AUC(Z=3.199,2.825,3.112 and 2.514,P＜0.05).Conclusion PCT,complement C3,CD4+T cell ratio,and CD8+T cell ratio are influencing factors for the occurrence of PB in children with RMPP,and their combined detection is beneficial for the early prediction of PB.

Objective:To analyze the genetic characteristics and evolutionary origin of hepatitis B virus (HBV) subgenotype D3 in China in 2020.Methods:Serum samples and demographic details from patients infected with HBV D3 subgenotype were collected. HBV genomic sequences were obtained by nested PCR amplification and subsequent sequencing. Phylogenetic analysis, nucleotide homology, amino acid mutation and evolution rate of the S protein were conducted by comparing with reference sequence using bioinformatics tools.Results:The complete HBV gene sequences of 14 samples of D3 subtype HBV were obtained. Compared with 97 reference sequences, it was found that the sequences with the highest homology were from India, Mongolia, Iran and China, with the homology ranging from 96.0% to 97.9%. Mutations of 24 amino acids were found in 14 strains of D3 subtype. Among them, T131A, Y134F and T140I were associated with immune escape-related mutations. The genetic diversity of HBV D3 subtype increased slowly before 1975, remained relatively constant from 1975 to 2000, and began to decline after 2000. Evolutionary rate analysis showed that samples QGLD D3-02 and 03 originated from a common ancestor with the Iranian reference strain in 1872, and the other 12 samples QGLD D3-04-17 originated from a common ancestor with the Mongolian reference strain in 1843.Conclusions:The gene sequence of HBV D3 subtype in China had the highest homology with reference sequences from India, Iran, Mongolia and China. Evolutionary rate analysis revealed that 14 cases of HBV D3 subtype originated from a common ancestor with reference strains from Mongolia and Iran, which enriched the sequence and evolution information of HBV D3 subtype and provided a reference basis for the molecular epidemiological study of HBV.

Objective:To analyze the influencing factors for special interests in rheumatology diseases in residents after their completion of standardized residency training.Methods:A questionnaire survey was conducted among general practitioners who participated in residential training in the base from September 1, 2011 to June 30, 2024, and the possible influencing factors were collected and analyzed.Results:Eighty-six cases (63.2%) of general practitioners expressed interest in rheumatology. A higher proportion of physicians showed interest in rheumatology when they engaged in the following activities: taking rheumatology as a subspecialty in practice on rheumtic diseases [16.3% (14/86) vs. 0 (0/50), χ2=15.93, P<0.001], taking night shifts during rheumatology rotation [57.0%(49/86) vs. 20% (10/50), χ2=17.60, P<0.001], studying with mentors of rheumatogy[89.5%(77/86) vs. 54.0%(27/50), χ2=22.19, P<0.001], participating in research on rheamatic diseases[16.3% (14/86) vs. 2.0% (1/50), χ2=6.57, P=0.010], involved in rheumatology outpatient teaching sessions [33.7%(29/86) vs. 8.0% (4/50), χ2=11.38, P<0.001], and receiving career guidance on mentors of rheumatology[39.5%(34/86) vs. 18.0% (9/50), χ2=6.78, P=0.012]. Multivariate logistic analysis revealed that the following were independent promoting factors for developing interest in rheumatology: taking rheumatology as a subspecialty in practice [ OR(95% CI) =3.82 (1.5,9.7), P=0.005], taking night shifts during rheumatology rotation [ OR(95% CI) =3.41 (1.25,9.28), P=0.017], and studying with mentors of rheumatology[ OR(95% CI) =6.44 (2.18,19.08), P<0.001]. Conclusion:Most residents expressed interest in rheumatology. Taking rheumatology as a practice sub-specialty, taking night shifts and during rotation and learning from mentors have a positive impact on residents interest in rheumatology after their completion of residency.
