Background: Optimizing cultivation techniques for traditional Chinese medicine has become a crucial means to improve the quality of medicinal materials. Microbial agents, as environmentally friendly and efficient plant growth promoters and soil conditioners, have increasingly attracted attention in eco-agriculture research. Objective: Our understanding remains limited regarding how the application of microbial agents, alone or in combination, affects changes in the rhizosphere microbiome and its association with the bioactive components of medicinal materials. Methods: In this study, Epimedium pubescens Maxim. was employed as a model plant to examine the effects of 2 microbial agents(Paenibacillus mucilaginosus and Bacillus subtilis) applied individually and in combination on plant growth and the accumulation of bioactive components. Additionally, this study explored the relationship between the rhizosphere microbiome and plant development. Results: The application of microbial agents increased the yield of E. pubescens leaves by 20.30% to 33.66% and enhanced the total flavonol glycosides content by 11.40% to 29.94%. Meanwhile, microbial treatments reshaped the rhizosphere microbiome, promoted the enrichment of beneficial microorganisms (e.g., Frankia and Paenibacillus), suppressed phytopathogenic fungi such as Didymella and Scytalidium, and enhanced the stability of the soil microbial co-occurrence network. The partial least squares path model suggested that microbial agents not only directly impact the quality of medicinal herbs but also indirectly alter the accumulation of bioactive components by modulating the soil microbiome. Conclusion: These findings deepen our understanding of the relationship between medicinal plant quality and rhizosphere microbiomes as mediated by microbial agents. They also provide a basis for designing and manipulating synthetic microbial communities to promote sustainable development in eco-agriculture.

Objective:To evaluate the efficacy and safety of intrasaccular flow disruptor in wide-necked intracranial aneurysms.Methods:One hundred and seventeen patients with wide-necked intracranial aneurysms treated with intrasaccular flow disruptor were collected from Department of Neurointervention (First Affiliated Hospital of Zhengzhou University), Department of Neurosurgery (Beijing Tiantan Hospital, Capital Medical University), Department of Cerebrovascular Surgery, Neurosurgery Center (Zhujiang Hospital, Southern Medical University), and Department of Neurosurgery (First Affiliated Hospital of Harbin Medical University) from August 2022 to March 2024. Raymond-Roy Occlusion Classification (RROC) was employed to evaluate aneurysm embolization immediately after procedure; cranial CT or MRI within 48 hours of embolization were performed to identify any new intracranial hemorrhage, subarachnoid hemorrhage, or new symptomatic cerebral infarction related to the intracranial aneurysms. Modified Rankin Scale (mRS) was used to assess the neurological function at discharge. Imaging follow-up and outpatient follow-up were performed at 6 months after embolization to evaluate the aneurysm occlusion degree and complications.Results:A total of 117 intrasaccular flow disruptors were implanted in 117 patients, with a technical success rate of 100%; 115 patients (98.3%) enjoyed successful one-time release of their disruptors, and 2 patients (1.7%) required retrieval and redirection of the disruptors before second successful attempt. Flow disruptor plus stent was performed in 13 patients (11.1%). Immediately after procedure, RROC grading I was noted in 3 patients, grading II in 51 patients and grading III in 63 patients. Cranial CT or MRI within 48 hours of embolization indicated no new intracranial hemorrhage, subarachnoid hemorrhage, or symptomatic cerebral infarction related to the intracranial aneurysms. All patients had mRS score of 0 at discharge. Eighty-three patients completed a 6-month follow-up (RROC grading I in 41 patients, grading II in 33 patients and grading III in 9 patients), without ischemic or hemorrhagic adverse events.Conclusion:The results of this study preliminarily suggest that intrasaccular flow disruptor is effective and safe in wide-necked intracranial aneurysms.

Objective:To evaluate the efficacy and safety of Neuroform Atlas stent-assisted coil embolization in patients with middle cerebral artery bifurcation aneurysms.Methods:A retrospective analysis was performed; the clinical data of 46 patients with middle cerebral artery bifurcation aneurysms accepted Neuroform Atlas stent-assisted coil embolization in First Affiliated Hospital of Zhengzhou University, Beijing Tiantan Hospital Affiliated to Capital Medical University, First Affiliated Hospital of Harbin Medical University, Zhujiang Hospital of Southern Medical University and First Affiliated Hospital of Chongqing Medical University from January 2022 to March 2024 were collected. There were 28 ruptured aneurysms (60.87%) and 18 unruptured aneurysms (39.13%). Follow-up was performed for more than 3 months; Raymond-Roy grading was used to evaluate the aneurysm embolization immediately after embolization and during follow-up; perioperative hemorrhagic or ischemic complications were recorded; modified Rankin Scale (mRS) was used to evaluate the prognosis of the patients at discharge and during follow-up (mRS score≤2: good prognosis, and mRS score>2: poor prognosis).Results:Coil embolization was successful in all 46 patients. DSA immediately after embolization showed that 41 patients (89.13%) had completely occluded aneurysms (Raymond-Roy grading I), 2 patients (4.35%) had residual aneurysm neck (Raymond-Roy grading Ⅱ) and 3 patients (6.52%) had partially occluded aneurysms (Raymond-Roy grading Ⅲ). Perioperative complications occurred in 5 patients, including 2 with postoperative cerebral infarction, 1 with hydrocephalus, 1 with postoperative pneumonia leading to respiratory failure, and 1 with stent thrombosis during embolization. Both at discharge and 3 months after embolization, 43 patients (93.48%) had good prognosis and 3 patients (6.52%) had poor prognosis. No obvious ischemic complications (such as stent restenosis) or hemorrhagic complications (such as re-rupture of the aneurysms) were found in all patients. Thirty patients (65.22%) had imaging follow-up for 6-12 months: 26 (86.67%) had Raymond-Roy grading I, 3 (10.00%) had Raymond-Roy grading II, and 1 (3.33%) had Raymond-Roy grading III.Conclusion:Neuroform Atlas stent-assisted coil embolization has good short-term efficacy and high safety in middle cerebral artery bifurcation aneurysms, but long-term follow-up observation is still needed to verify its efficacy.

Flow diverter (FD) devices have gradually become the mainstream approach for interventional treatment of intracranial aneurysms. In-stent stenosis (ISS) is a common complication after FD implantation, which can lead to ischemic events and affect the prognosis of patients. Current studies have shown that ISS occurrence is closely related to hemodynamic changes. From the perspective of hemodynamics, this article reviews the research progress of mechanisms, evaluation methods and treatments of ISS after FD implantation, in order to provide reference for clinical practice.

Objective:To investigate the safety and efficacy of Pipeline embolization device (PED) Shield in intracranial unruptured saccular aneurysms.Methods:This is a retrospective cohort study; 124 patients with intracranial unruptured saccular aneurysms treated with PED Shield at Department of Cerebrovascular Surgery, Neurosurgery Center, Zhujiang Hospital, Southern Medical University from July 2023 to October 2024 were enrolled. Intraoperative device-related complications and occurrence of hemorrhagic and ischemic complications within 30 days of the procedure were recorded. The clinical results and imaging results (degrees of stent patency and aneurysm occlusion rate) 6 months after follow-up were statistically analyzed. Modified Rankin scale (mRS) score>2 was defined as poor prognosis in clinical follow-up, and grade D according to O'Kelly Marotta (OKM) classification was considered as complete aneurysm occlusion in imaging follow-up.Results:Eighty-seven females and 37 males, aged (56.44±12.17) years (ranging from 27 to 80 years) were enrolled, with a maximum aneurysm diameter of 5.12 (3.73, 7.24) mm. Among the 124 patients, incidence of intraoperative instrument-related complications was 6.5% (8/124); and within 30 days of the procedure, incidence of ischemic complications was 4.8% (6/124) and that of hemorrhagic complications was 1.6% (2/124). Eighty-four patients had a 6-month clinical follow-up, with 1 patient (1.2%) having poor prognosis. Eighty-four patients (67.7%) completed a 6-month imaging follow-up: complete occlusion rate of aneurysms was 82.1% (69/84), incidence of in-stent stenosis (stenosis degree ≥25%) was 4.8% (4/84), and no symptomatic in-stent stenosis was found.Conclusion:Result of this study shows that PED Shield may be an effective and safe clinical option for intracranial unruptured saccular aneurysms.

Objective:To investigate the relevant factors for rupture of basilar tip aneurysms.Methods:This is a retrospective cohort study. Patients who underwent cerebrovascular digital subtraction angiography at Department of Cerebrovascular Disease Surgery,Zhujiang Hospital of Southern Medical University from July 2008 to February 2023 and were confirmed to have basilar tip aneurysms were retrospectively analyzed. There were 45 males and 56 females, aged (57.5±10.2) years (range: 36 to 76 years); the maximum diameter of the basilar tip aneurysm ( M(IQR)) was 6.85 (5.79) mm (range: 1.28 to 27.48 mm). Finally, 101 basilar tip aneurysms were included, and divided into two groups based on whether the basilar tip aneurysm ruptured or not. There were 37 cases (36.6%) in the ruptured group and 64 cases (63.4%) in the unruptured group. Data were analyzed using independent t-test, Mann-Whitney U test, chi-square test, or Fisher′s exact test, as appropriate, and predictive factors for rupture of basilar tip aneurysms were explored by Logistic regression analysis. Variance inflation factors was used for analysis of collinearity. Results:The univariate results showed statistically significant differences between the ruptured and unruptured groups in terms of aneurysm neck width, basilar artery diameter, mean diameter of the parental artery, the ratio of neck width to parent artery diameter, aneurysm width and maximum diameter of the aneurysm (all P<0.05). In multivariate analysis, basilar artery diameter ( OR=0.347, 95% CI:0.176 to 0.687, P=0.002), and NRP ( OR=0.366, 95% CI:0.192 to 0.696, P=0.002) were predictive factors for rupture of aneurysms occurring at the basilar tip. There was no multiple covariance between NRP and basilar artery diameter in the analysis of covariance (VIF=1). Conclusion:Smaller basilar artery diameter and smaller NRP are relevant factors for rupture of basilar tip aneurysms.

Objective:To study the clinical efficacy and impact on quality of life of the first administration of different doses of 131iodine ( 131I) therapy in patients with differentiated thyroid cancer (DTC) after surgical resection. Methods:A total of 97 DTC patients who underwent elective surgical resection at Hongqi Hospital Affiliated to Mudanjiang Medical University from June 2022 to June 2024 were selected and divided into a high-dose group ( n = 49) and a low-dose group ( n = 48) based on their first postoperative treatment with different doses of 131I. All patients underwent DTC endoscopic thyroidectomy. The high-dose group received > 150 - 200 mCi 131I treatment after surgery, while the low-dose group received 100 - 150 mCi 131I treatment after surgery. Both groups of DTC patients were followed up for 12 months. A comparison was conducted between the two groups regarding the success rate of clearing residual thyroid tissue (referred to as thyroid clearance), disease-free survival rate, recurrence rate, incidence of adverse reactions, and changes in quality of life before and after treatment. Results:There was no statistically significant difference in the success rate of thyroid clearance between the two groups of DTC patients (χ 2 = 1.43, P = 0.232). The disease-free survival rate of DTC patients in the low-dose group was higher than that in the high-dose group (χ 2 = 4.86, P = 0.027), and the recurrence rate was lower than that in the high-dose group (χ 2 = 4.86, P = 0.027). The incidence of adverse reactions in DTC patients in the low-dose group was lower than that in the high-dose group (χ 2 = 4.59, P = 0.032). The scores of the short form 36 health survey (SF-36) of both groups of DTC patients after treatment were higher than those before treatment ( P < 0.05), and the SF-36 scores of DTC patients in the low-dose group were higher than those in the high-dose group after treatment ( P < 0.001). The scores of the thyroid cancer specific quality of life (THYCA-QoL) of both groups of DTC patients after treatment were lower than those before treatment ( P < 0.05), and the THYCA-QoL scores of DTC patients in the low-dose group were lower than those in the high-dose group after treatment ( t = 4.48, P < 0.001). Conclusions:The initial treatment effect of different doses of 131I after DTC surgical resection is comparable, but the low-dose 131I can improve the disease-free survival rate, reduce adverse reactions, and improve the quality of life of patients, which is worthy of clinical practice.
