Objective To investigate the role of network platform for treatment and rescue of acute and severe cerebrovascular diseases in improving treatment level of patients with acute ischemic stroke.Methods The differences of number of patients accepted venous thrombolysis, number of patients accepted emergency intravascular interventional treatment, and time from admission to intravenous thrombolysis (door to needle time [DNT]) were analyzed in patients with acute ischemic stroke admitted to our hospital in the first year (2016) and the second and third years (2017 and 2018) of construction of network platform for treatment and rescue of acute and severe cerebrovascular diseases in Yunfu city. The National Institutes of Health Stroke Scale (NIHSS) scores were compared in 120 patients selected randomly from online referral (study group,n=60) and non-online referral (control group,n=60) within the same time periods in 2018.Results In 2017 and 2018, the number of patients accepted intravenous thrombolysis was 85 and 103, respectively, and the rate of intravenous thrombolysis was 9.92% and 9.83%; they were all significantly larger/higher than those in 2016 (n=50, 6.97%,P<0.05). In 2017 and 2018, the number of patients accepted emergency endovascular treatment was 56 and 129, respectively, and the emergency endovascular treatment rate was 6.53% and 12.31%; they were all higher than those in 2016 (n=44 and 6.14%), and the differences between those in 2018 and 2016 were statistically significant (P<0.05). The DNT ([82.00±18.75] min in 2017 and [77.00±32.17] min in 2018) was significantly shorter than that in 2016 ([109.00±30.58] min,P<0.05). The NIHSS scores of the study group and control group were 4.70±3.64 and 8.90±5.62, respectively, after one week of treatment, both of which were lower than those before treatment (14.30±6.29 and 13.60±6.37); and after treatment, the NIHSS scores of the treatment group were statistically lower than those of the control group (P<0.05). Conclusion Construction and effective operation of network platform for treatment and rescue of acute and severe cerebrovascular diseases is an effective guarantee to improve the success rate of treatment for patients with acute ischemic stroke.

Objective To explore the efficacy of middle and high (mid-high) flow intracranial-external vascular bypass in treatment of complex intracranial aneurysms and selection of grafts. Methods The clinical data of 79 patients with complicated intracranial aneurysms treated by mid-high flow extracranial-intracranial bypass in our hospital from August 2010 to October 2017 were collected retrospectively. The grafts were radial artery (n=21), saphenous vein of the calf segment (n=29) or thigh saphenous vein segment (n=29). The efficacy was determined based on Glasgow outcome scale (GOS) scores at discharge and modified Rankin scale (mRS) scores at follow-up, and the differences of occlusion in different types of grafts were analyzed. Results CTA showed patency of the grafts in all patients one d after surgery. There were 6 patients having vascular occlusion: 2 patients (the grafts at saphenous vein of the calf segment ) were occluded 3 and 4 d after surgery, without symptom; 2 patients (the grafts at the radial artery), with decreased limb muscle strength, were occluded 5 and 25 d after procedure; 2 patients ( the grafts at the saphenous veins of the calf segment) were occluded 6 months after procedure without any symptom. There were 4 patients developed cerebral ischemia after operation: one had cerebral infarction and three had vasospasm. GOS scores at discharge and mRS scores at follow-up showed that 78 patients had improved symptoms and good prognosis; one patient showed no improvement in symptoms and plant survival. Conclusion Mid-high flow extracranial-intracranial bypass for treatment of complex intracranial aneurysms is effective; the graft should be individually selected based on preoperative assessment results.

OBJECTIVES:
Glioma is the most common malignant tumor in the central nervous system, and the hypoxic microenvironment is prevalent in solid tumors. This study aims to investigate the up-regulation of genes under the condition of hypoxia and their roles in glioma growth, as well as their impact on glioma prognosis.
METHODS:
The hypoxia-related dataset with glioma was screened in the Gene Expression Omnibus database (GEO), and the differentially expressed genes were analyzed between hypoxia and normoxia through bioinformatics, and chromosome 10 open reading frame 10 (C10orf10) was verified and screened in hypoxia-treated cells through real-time PCR and Western blotting. The Cancer Genome Atlas (TCGA) and the Chinese Glioma Genome Atlas (CGGA) datasets were downloaded to analyze the mRNA expression of C10orf10 in different grades of glioma and its impact on prognosis. The glioma specimens and follow-up data of 68 gliomas who underwent surgical treatment in Xiangya Hospital of Central South University from March 2017 to January 2021 were collected, and real-time PCR was used to detect the mRNA expression of C10orf10 in different grades of glioma, and the Kaplan-Meier method was used to analyze the relationship between the expression C10orf10 and prognosis. The glioma cells, which could interfere the expression of C10orf10, were constructed, and the effect of C10orf10 on the proliferation of glioma cells was evaluated by cell counting kit-8 (CCK-8) and colony formation assays.
RESULTS:
Compared with the condition of normoxia, the expression levels of C10orf10 mRNA and protein were significantly up-regulated in glioma cells under hypoxia (P<0.001), and the mRNA expression level of C10orf10 in glioma tissues was up-regulated with the increase of WHO grade in glioma (P<0.001). Based on Kaplan-Meier survival analysis, the higher the mRNA expression level of C10orf10 was, the shorter the survival time of the patient was (P<0.05). And the expression of C10orf10 mRNA was higher in recurrent gliomas than that in primary gliomas in the CGGA database (P<0.001). Knockdown of C10orf10 could significantly inhibit the growth of glioma cells both under hypoxia and normoxia (both P<0.001).
CONCLUSIONS
The expression level of C10orf10 can promote the proliferation and prognosis of glioma, which is expected to become a prognostic marker and therapeutic target for glioma.
