AIM To investigate the variations in mercury dissolution from HgS-containing traditional medicines in three kinds of simulated gastrointestinal dissolution media.METHODS 39 batches of 15 types of HgS-containing traditional medicines were collected,total mercury content and dissolved mercury concentrations in simulated gastric fluid,simulated intestinal fluid,and L-cysteine-containing simulated intestinal fluid were measured.The maximum daily intake of total mercury and soluble mercury was calculated based on the maximum daily clinical dosage.RESULTS Among the 15 types of medicines,the maximum daily intake of total mercury varied by 156 times,the daily intake of soluble mercury varied by 3 502 times in simulated gastric fluid,313 times in simulated intestinal fluid,and 10 663 times in L-cysteine-containing simulated intestinal fluid,approximately.CONCLUSION For the 15 types of HgS-containing traditional medicines,the daily maximum intake of soluble mercury showed greater variations than that of total mercury.Soluble mercury concentration is more closely correlated with intestinal absorption of mercury and thus represents a more rational quality control indicator for HgS-containing traditional medicines.

Compared with matrix-assisted laser desorption ionization mass spectrometry(MALDI-MS)using organic small molecule matrix,surface-assisted laser desorption ionization mass spectrometry(SALDI-MS)based on nanomaterial matrix is more effective in analysis of small molecule compounds.Ion sputtering instruments have obvious advantages for applying inorganic nanomatrix.In this work,the carbon-platinum material was sputtered onto a glass cover slip using an ion sputtering instrument to form a carbon-platinum(C-Pt)composite nanomatrix,and an SALDI-MS analytical method was thus established based on the prefabricated C-Pt composite matrix.The experimental results showed that the C-Pt composite nanomatrix could significantly improve the signal intensity and signal-to-noise ratio of the mass spectrum peaks of the components to be measured.The ratio of carbon to platinum,the duration of ion sputtering,and the laser power in mass spectrometer were investigated to select the optimal C-Pt matrix prefabricated conditions and SALDI-MS experimental conditions.Using the prefabricated C-Pt composite matrix,the melittriose and daidzein sample solution were applied as sample to examine repeatability.The results showed that the intra-point repeatability(RSD)was≤4.8%and the inter-point repeatability(RSD)was≤6.4%.The quercetin and melitriose were applied as model samples,and a linearity between MS peak intensity and respective concentration in the range of 0.05-1.0 mg/mL was found,with linear correlation coefficients(R2)greater than 0.994,showing good potential for quantitative and imaging analysis.Then,the prefabricated C-Pt composite matrix was applied to SALDI-MS analysis of the 50%ethanol extract of soybean,and 15 kinds of compounds including oligosaccharides and triglycerides were identified from the mass spectra.Furthermore,the C-Pt matrix was employed in SALDI-MS imaging for the compositions in corn tissue section,and the results showed that diglycerides and triglycerides were mainly distributed in the corn embryo and around the embryo,and the distribution of oligosaccharides was relatively even.

Aim To investigate the antidepressant mechanism of hyperforin via the utilization of single-cell sequencing technology.Methods C57BL/6 mice were randomly divided into the control group,depres-sion model group,and hyperforin intervention group.The chronic unpredictable mild stress(CUMS)model was induced and drug interventions were administered for 28 d.Behavioral experiments were conducted to as-sess depressive symptoms,and hippocampal tissue was collected for single-cell RNA sequencing.Key cell populations and differentially expressed genes across groups were identified,followed by PPI network,GO,and KEGG enrichment analysis.Results Behavioral experiments indicated that CUMS successfully induced depressive symptoms in mice,while hyperforin im-proved depressive behavior.In the depression model group,the proportion of brain perivascular macrophages(PVM)increased,and this proportion decreased after hyperforin intervention,approaching the level seen in the control group.The top 20 common differentially ex-pressed genes in the PVM subpopulation were Saa3,Hbb-bs and Ccl24.PPI network analysis identified core targets,including Ccl2,Dhx9,C3,Msr1,Cxcl2 and Cx3cr1.KEGG enrichment analysis revealed pathways related to chemokines,phagosome formation,and inosi-tol phosphate metabolism.Conclusion The antide-pressant mechanism of hyperforin may be related to the regulation of Ccl24 and its related chemokine signaling pathway by PVM.

Objective:To explore the efficacy and safety of embolization of anterior cranial fossa dural arteriovenous fistula (ACF-DAVF) via different arterial approaches, and provide evidence for individualized treatment of ACF-DAVF. Methods:A retrospective study was performed; 25 patients with ACF-DAVF admitted to Department of Cerebrovascular Surgery, Neurosurgery Center, Zhujiang Hospital, Southern Medical University from January 2020 to December 2023 were enrolled. Vascular approaches, including the anterior cerebral artery ( n=7), facial artery ( n=3), middle meningeal artery ( n=8), ophthalmic artery ( n=6), and vein ( n=1), were selected based on angioarchitectural features and microcatheter accessibility. Fistula and proximal draining vein occlusions were confirmed by immediate post-embolization digital subtraction angiography (DSA), and perioperative complications were recorded. At a 6-month follow-up, prognoses were assessed by modified Rankin Scale (mRS), and DSA or MRA was performed to detect the recurrence of ACF-DAVF. Results:Six patients had complete embolization and 2 patients had near-total embolization of the fistula and proximal draining vein immediately after embolization via middle meningeal artery approach; 4 patients achieved complete embolization and 2 patients achieved near-total embolization via ophthalmic artery approach; 6 patients achieved complete embolization and one patient achieved near-total embolization via anterior cerebral artery approach; 3 patients achieved complete embolization via facial artery approach; one patient achieved complete embolization via venous approach. No perioperative intracranial hemorrhage or central retinal artery occlusion was noted. Follow-up for 6 months was performed in 25 patients: mRS score was 0 in 19 patients, 1 in 2 patients, and 2 in 4 patients; DSA in 19 patients and MRA in 6 patients indicated no ACF-DAVF recurrence. Conclusion:Based on the angioarchitectural features and microcatheter accessibility, individualized selection of vascular approaches for ACF-DAVF embolization can achieve better efficacy and safety.

Traditional Chinese medicine (TCM) is a well-accepted therapy for atopic dermatitis (AD). However, there are currently no evidence-based guidelines integrating TCM and Western medicine for the treatment of AD, limiting the clinical application of such combined approaches. Therefore, the China Association of Chinese Medicine initiated the development of the current guideline, focusing on key issues related to the use of TCM in the treatment of AD. This guideline was developed in accordance with the principles of the guideline formulation manual published by the World Health Organization. A comprehensive review of the literature on the combined use of TCM and Western medicine to treat AD was conducted. The findings were extensively discussed by experts in dermatology and pharmacy with expertise in both TCM and Western medicine. This guideline comprises 23 recommendations across seven major areas, including TCM syndrome differentiation and classification of AD, principles and application scenarios of TCM combined with Western medicine for treating AD, outcome indicators for evaluating clinical efficacy of AD treatment, integration of TCM pattern classification and Western medicine across disease stages, daily management of AD, the use of internal TCM therapies and proprietary Chinese medicines, and TCM external treatments.

This study examines the effects of zearalenone(ZEA)on the survival and function of lu-teinized granulosa cells,and studies the role of activating transcription factor 6(ATF6)in regula-ting apoptosis and functional abnormalities of luteinized granulosa cells induced by ZEA.An in vitro model of luteinized granulosa cells was utilized to examine the effects of ZEA treatment on apoptosis,hormone secretion,and the expression of relevant proteins.Furthermore,the expression of ATF6 was manipulated using siRNA to elucidate its regulatory function in the ZEA-induced damage of luteinized granulosa cells in mice.Our findings revealed that ZEA inhibited the activity of luteinized granulosa cells and reduced the secretion of estradiol(E2)and progesterone(P4)in a dose-dependent manner.The expression levels of p-IRE1,ATF6 and StAR in both low(20 pmol/L)and high(40 μmol/L)ZEA groups were significantly increased after 24 h(P<0.05).GRP78 had no significant change at low concentration treatment(P>0.05),but significantly increased at high concentration treatment(P<0.05).Similarly,ATF4 and p-EIF2α had no significant change at low concentration treatment(P>0.05),but significantly decreased at high concentration treat-ment(P<0.05).HSD3B2 and CYP19A1 were significantly decreased in both low and high concentration treatments(P<0.05).After 48 h of treatment,ATF6 and GRP78 were significantly increased in both low and high concentration treatments(P<0.05).p-IRE1 was significantly de-creased at low concentration treatment(P<0.05),but remained unchanged at high concentration treatment(P>0.05).ATF4,p-EIF2α,HSD3B2 and CYP19A1 were significantly decreased in both low and high concentration treatments(P<0.05).St AR was significantly increased in both low and high concentration treatments(P<0.05).Interference with the expression of ATF6 could sig-nificantly reduce the apoptosis induced by low concentration group(P<0.05),and enhanced the hormone secretion in both high and low concentration groups(P<0.05).In conclusion,ZEA can cause damage to luteinized granulosa cells and activate ATF6 signaling pathway.Interference with ATF6 can alleviate apoptosis and hormone secretion disturbance induced by low concentration ZEA,but has limited effect on damage caused by high concentration ZEA.

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.
