Objective To investigate the therapeutic effect of the ultra-early stent-assisted coil embolization of the ruptured intracranial aneurysms. Methods The clinical data of 13 patients with ruptured intracranial aneurysm treated by ultra-early stent-assisted coil embolization were analyzed retrospectively. The preoperative Hunt-Hess gradeⅠ-Ⅱ was in 7 cases,gradeⅢ was in 4 cases,and grade Ⅳ was in 2 cases. The patients were treated with stent-assisted coil embolization under the general anesthesia with endotracheal intubation within 24 h of aneurysm rupture. The postoperative embolization was assessed according to the Raymond grading standard. The postoperative complications and the assessment of the follow-up results from 1 to 6 months after procedure according to the modified Rankin scale (mRS ) scores were observed. Results All 11 patients recovered well,1 case had postoperative hemiplegia,1 case had postoperative bleeding,and none of them died. During the follow-up period,no patients had rebleeding, 1 had recurrence,and DSA revealed that the patient was embolized completely at 2 months after reembolization. Conclusion The method of ultra-early stent-assisted coil embolization of ruptured intracranial aneurysms is feasible. It may improve the cure rate of the ruptured aneurysms and improve the prognosis of patients.

Objective:To investigate the safety and effectiveness of multi-stent overlapping assisted coil embolization for ruptured intracranial blood blister-like aneurysms (BBA).Methods:Patients with intracranial BBA admitted to the Affiliated Quanzhou First Hospital of Fujian Medical University and treated with multi-stent overlapping assisted coil embolization from January 2013 to January 2019 were enrolled retrospectively. The embolization rate immediately after procedure, modified Rankin Scale (mRS) score at discharge, aneurysm embolization rate, recurrence rate and mRS scores at 3 months after procedure were collected.Results:A total of 38 patients with BBA were enrolled, including 21 females (55.3%) and 17 males (44.7%); their age was 54±9.3 years (range, 29-71 years); the maximum diameter of aneurysm was 5.1±1.0 mm, and the diameter of aneurysm neck was 4.9±0.7 mm. Raymond grading showed that the complete embolization rate immediate after procedure was 71.1%, the residual rate of aneurysmal neck was 18.4%, and the residual rate of aneurysmal body was 10.5%. During the perioperative period, 2 patients had stent thrombosis and 2 had intraoperative aneurysm hemorrhage. Imaging follow-up at 3 months after procedure showed that the aneurysms of 31 cases (83.8%) disappeared completely, 4 (10.8%) improved, and 2 (5.4%) recanalized. The good clinical outcome rate (mRS score ≤ 2) was 81.1%, 1 patient (2.6%) died, and no postoperative rebleeding occurred.Conclusion:Multi-stent overlapping assisted coil embolization is a safe and effective surgical method for the treatment of ruptured intracranial BBA.

OBJECTIVE
To establish the quality standard of Triadica cochinchinensis and to perform the acute toxicity study.
METHODS
Appearance properties, powder microscopic identification, and thin-layer chromatography(TLC) identification were researched. The specific chromatogram was established by HPLC. The content of cadmium(Cd), lead(Pb), arsenic(As), copper(Cu), and mercury(Hg) was determined by inductively coupled plasma-mass spectrometry(ICP-MS). Acute toxicity was studied by maximum dose.
RESULTS
The outer skin of herbs was dark brown, and the inner surface was light yellow brown and fibrous. Besides, crystal sheath fiber was common, and calcium oxalate clusters arranges in rows. In the TLC diagram of the test product, the fluorescent spots of the same color were displayed at the corresponding position of the control product(scopoletin, isofraxidin). Five common peaks were calibrated in the characteristic map and the three characteristic peaks(scopoletin, isofraxidin, dimethylfraxetin) were recognized. The content of the measured heavy metal elements was lower than the national limit standard. The linear correlation coefficient was R2 > 0.999. The precision, stability, repetitive RSD were < 10%. The average recovery rate of the added sample was 80%−120%, and the RSD was < 10%. The maximum dose of the acute toxicity test was 184.09 g·kg−1. The 14 d internal body mass, food intake, organ-body ratios, the serum glutamic pyruvic transaminase, glutamic oxaloacetic transaminase, blood urea nitrogen, and creatinine were not significantly different by comparing with the normal controls. Therefore, no significant toxicity was observed.
CONCLUSION
The established standard can provide a reference for evaluating the quality of Triadica cochinchinensis. The heavy metal content of ten batches of medicinal materials is within the safe range. Acute toxicity test show that there is no obvious significant adverse teactions after oral administration, and the safe dose range is large, which can provide a reference for the subsequent development and utilization.
