Objective: To evaluate the inhibition of human endostatin on tumor growth and metastasis of lung adenocarcinoma LA795 in mice. Methods: Recombinant human endostatin was purified from pCX expressed endostatin clones. Plasminogen was purified from outdated human plasma by affinity chromatography, and human angiostatin was produced from human plasminogen digested by elastase and purified by affinity chromatography. LA795 cells were inoculated subcutaneously into the dorsa of T739 mice, and the mice were randomized into 3 groups. From the 1Oth day, the first group was given 20 mg/kg of recombinant human endostatin s.c. qd, the second was treated daily s. c. of 7.5 mg/kg of human angiostatin, and the third group received daily s.c. with equal volumes of PBS for 14 days. Volumes of the subcutaneous tumors, lung weights, the number of lung surface metastases and mice life span were observed. The results were analyzed by q-test. Results: The tumor volumes of both the 1 st and the 2nd groups increased slowly. From the 8th day after being treated, the tumor volumes were decreasing. However, in the 3rd group, the tumor volumes increased continuously. The lung weight and the number of lung surface metastases of the 1st and 2nd groups were less than that of the 3rd group. The average survival periods of the 1st and 2nd groups were longer than that of the 3rd group. Conclusion: Human endostatin and angiostatin have strong inhibitory effects both on growth of primary tumor and metastasis of lung adenocarcinoma LA795, and prolongs the survival period of the tumor-bearing mice.

Objective To study the ability of S100B to predict the clinical outcomes and complications after aneu?rysmal subarachnoid hemorrhage (aSAH). Method This study is a one-center and consecutive recruitment. Plasma S100B levels were measured by enzyme-linked immune-sorbent assay (ELISA) within 72 hours after onset. The charac?teristics, treatment patterns, complications and outcomes of patients were also analyzed. Results The S100B levels of aSAH patients were higher than that of health controls(28.55 pg/mL vs. 21.20 pg/mL, P<0.001). S100B levels (P=0.05), Hunt-Hess higher scales (P<0.001), delayed cerebral ischemia (P<0.001) and hydrocephalus (P=0.028) were associated with poor outcomes. S100B also can predict complications in hospital. Conclusions The levels of S100B rise during acute phase of aSAH and S100B may be a useful biomarker to predict functional outcomes and complications in hospital.

Objective:To investigate the pathogenesis, selection of endovascular treatment (EVT) strategies, and efficacies of acute vertebrobasilar artery occlusion (AVBAO) of different lesion sites.Methods:One hundred and five patients with AVBAO, admitted to and accepted EVT in our hospital from February 2017 to September 2019, were chosen in our study. The data of disease onset, imaging findings, EVT status, perioperative complications, and prognoses of these patients were collected. According to DSA results, the involved lesions were divided into 4 sites: the upper segment of basilar artery (BA), the middle segment of BA, the lower segment of BA, and the intracranial segment of vertebral artery (V4 segment), and patients with tandem lesions would be recorded as distal lesions. The risk factors, EVT strategies, and prognoses 90 d after follow-up (modified Rankin scale [mRS] scores≤3: good prognosis) were compared in patients with 4 different lesion sites.Results:There were significant differences in etiological classifications and percentage of patients combined with atrial fibrillation among patients with 4 different lesion sites ( P<0.05). There was significant difference in proportion of patients accepted emergency stent implantation among patients with 4 different lesion sites ( P<0.05): those with lesions at the V4 segment had the highest proportion of patients accepted emergency stent implantation (79.55%), followed by those with lesions at the lower segment of BA (50.00%). There was significant difference in EVT time (the time from arterial puncture to successful recanalization of occluded vessels) among patients with 4 different lesion sites ( P<0.05): the EVT time in patients with lesions at the middle segment of BA was the shortest (87.5 [58.5, 130.8] min), and the EVT time in patients with lesions at the lower segment of BA was the longest (115.0 [81.0, 163.0] min). There was no statistical difference among patients with different lesion sites in good prognosis rate 90 d after follow-up ( P>0.05). Conclusion:The pathogenesis of patients with different AVBAO lesion sites is different, so different EVT strategies should be adopted.
