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 explore the correlation between conventional ultrasound and contrast-enhanced ultrasound features and invasive histological features of T 1a clear cell renal cell carcinoma (ccRCC). Methods:A retrospective case series study was conducted. Sixty-seven T 1a ccRCC patients who were admitted to Shanxi Province Cancer Hospital from May 2018 to August 2023 were selected. According to the World Health Organization (WHO)/International Society of Urology and Pathology (ISUP) renal tumor grading system, the patients were divided into the low-grade group (WHO/ISUP grades 1-2, 53 cases) and the high-grade group (WHO/ISUP grades 3-4, 14 cases). The conventional ultrasound and contrast-enhanced ultrasound characteristics of two groups of patients were compared. Multivariate logistic regression model was used to analyze the independent factors of conventional ultrasound and contrast-enhanced ultrasound related to T 1a ccRCC with WHO/ISUP high grade. Results:There were no statistically significant differences in clinical characteristics between the two groups of patients (all P > 0.05). In conventional ultrasound examination, the proportion of patients with tumor exophytic rate <50% in the high-grade group was higher than that in the low-grade group [64.3% (9/14) vs. 34.0% (18/53)], and the difference was statistically significant ( χ2 = 4.23, P = 0.040); there were no statistically significant differences in the distribution of patients with different tumor maximum diameter, laterality, polarity, depth, echo, boundary, and shape between the two groups (all P > 0.05). In contrast-enhanced ultrasound examination, the proportion of patients lack of pseudocapsule sign in the high-grade group was higher than that in the low-grade group [57.1% (8/14) vs. 24.5% (13/53)], and the difference was statistically significant ( χ2 = 4.06, P = 0.044); there were no statistically significant differences in the distribution of patients with different perfusion mode, enhancement degree, enhancement uniformity, and regression mode between the two groups (all P > 0.05). Multivariate logistic regression analysis showed that the conventional ultrasound tumor exophytic rate < 50% (compared to exophytic rate ≥ 50%, OR = 3.732, 95% CI: 1.019-13.664, P = 0.047) and the absence of pseudocapsule sign (compared to the presence of pseudocapsule sign, OR = 4.357, 95% CI: 1.201-15.804, P = 0.025) on contrast-enhanced ultrasound were independent risk factors for high-grade T 1a ccRCC. Conclusions:T 1a ccRCC with the exophytic rate <50% and absence of pseudocapsule sign may have invasive histological features.

Objective To investigate the risk factors influencing postoperative recurrence of abdominal wall endometriosis(AWE).Methods A retrospective analysis was conducted on clinical data of 225 AWE patients who underwent surgery between January 2015 and December 2021.The follow-up period ranged from 30 to 108 months(mean,62.2±23.3 months).There were 16 cases of recurrence and 209 cases of non-recurrence.Univariate analysis and multivariate logistic regression were performed to identify factors associated with postoperative recurrence.Results Univariate analysis revealed that prior AWE resection history,preoperative VAS score,intraoperative lesion number,maximum diameter,and postoperative medication were significantly correlated with recurrence(P＜0.05).Multivariate logistic regression identified three independent risk factors for recurrence:prior AWE resection history(OR=4.082,95％ CI:1.019-16.354,P=0.047),multiple intraoperative lesions(OR=5.275,95％ CI:1.560-17.834,P=0.007),and absence of postoperative pharmacotherapy(OR=6.256,95％ CI:1.479-26.457,P=0.013).Conclusion Patients with a history of prior AWE excision,multiple lesions,or lack of postoperative pharmacotherapy are at higher risk of recurrence of AWE.

Abiotic stresses substantially affect the growth and development of plants. Plants have evolved multiple strategies to cope with the environmental stresses, among which transcription factors play an important role in regulating the tolerance to abiotic stresses. Basic leucine zipper transcription factors (bZIP) are one of the largest gene families. The stability and activity of bZIP transcription factors could be regulated by different post-translational modifications (PTMs) in response to various intracellular or extracellular stresses. This paper introduces the structural feature and classification of bZIP transcription factors, followed by summarizing the PTMs of bZIP transcription factors, such as phosphorylation, ubiquitination and small ubiquitin-like modifier (SUMO) modification, in response to abiotic stresses. In addition, future perspectives were prospected, which may facilitate cultivating excellent stress-resistant crop varieties by regulating the PTMs of bZIP transcription factors.

Objective To compare the effect of three-dimensional visual (3DV) model, three-dimensional printing (3DP) model and computer-aided design (CAD) modified 3DP model in video-assisted thoracoscopic surgery (VATS) sublobular resection. Methods The clinical data of patients who underwent VATS sublobular resection in the Affiliated Hospital of Hebei University from November 2021 to August 2022 were retrospectively analyzed. The patients were divided into 3 groups including a 3DV group, a 3DP group and a CAD-3DP group according to the tools used. The perioperative indexes and subjective evaluation of operators, patients and their families were compared. Results A total of 22 patients were included. There were 5 males and 17 females aged 32-77 (56.95±12.50) years. There were 9 patients in the 3DV group, 6 patients in the 3DP group, and 7 patients in the CAD-3DP group. There was no statistical difference in the operation time, intraoperative blood loss, drainage volume, hospital stay time or postoperative complications among the groups (P>0.05). Based on the subjective evaluations of 4 surgeons, the CAD-3DP group was better than the 3DV group in the preoperative planning efficiency (P=0.025), intuitiveness (P=0.045) and doctor-patient communication difficulty (P=0.034); the CAD-3DP group was also better than the 3DP group in the overall satisfaction (P=0.023), preoperative planning difficulty (P=0.046) and efficiency (P=0.014). Based on the subjective evaluations of patients and their families, the CAD-3DP group was better than the 3DP group in helping understand the vessel around the tumor (P=0.016), surgical procedure (P=0.020), procedure selection (P=0.029), and overall satisfaction (P=0.048); the CAD-3DP group was better than the 3DV group in helping understand the tumor size (P=0.038). Conclusion CAD-modified 3DP model has certain advantages in pre-planning, intraoperative navigation and doctor-patient communication in the VATS sublobectomy.
