The median follow-up of the malignant glioma patients who received surgical resection combined with radiochemotherapy is 16 months. The recurrence of malignant glioma is unavoidable. Although the patient with recurrent glioblastoma has multiple choices of therapy, the 5-year survival rate is still less than 5%, and the average survival time is less than 12 months. Currently, there is no single second-line drug can have survival benefits.

Anterior communicating artery(ACoA)aneurysms account for the largest proportion of intracranial aneurysms and are the most likely to rupture.[1]The main treatment methods are endovascular embolization and traditional craniotomy clipping.[2]With the rapid development of interventional materials and technologies in the last two decades,many medical centers have adopted endovascular embolization as the preferred treatment for intracranial ***,some aneurysms still require traditional craniotomy *** endoscopy technology has also developed rapidly in recent years.[3]Because intracranial aneurysms are mostly within the circle of Willis and occur on the ventral side of the skull base,a few neurosurgeons have tried to use an endoscopic endonasal approach(EEA)for clipping.[4-6]However,the number of cases reported in the literature is small and more anatomical studies are needed to deeply analyze the approach and technique.

Background： Cerebral arteriovenous malformation （cAVM） is a type of vascular malformation associated with vascular remodeling, hemodynamic imbalance, and inflammation. We detected four angioarchitecture-related cytokines to make a better understanding of the potential aberrant signaling in the pathogenesis of cAVM and found useful proteins in predicting the risk of cerebral hemorrhage. Methods： lmmunohistochemical analysis was conducted on specimens from twenty patients with cAVM diagnosed via magnetic resonance imaging and digital subtraction angiography and twenty primary epilepsy controls using antibodies against vascular endothelial growth factor receptor-2 （VEGFR-2）, matrix metalloproteinase-9 （MMP-9）, vascular cell adhesion molecule （VCAM- 1 ）, and endothelial nitric oxide synthase （eNOS）. Western blotting and real-time fluorescent quantitative polymerase chain reaction （PCR） were performed to determine protein and mRNA expression levels. Student＇s t-test was used for statistical analysis. Results： VEGFR-2, MMP-9, VCAM-1, and eNOS expression levels increased in patients with cAVM compared with those in normal cerebral vascular tissue, as determined by immunohistochemical analysis. In addition, Western blotting and real-time PCR showed that the protein and mRNA expression levels ofVEGFR-2, MMP-9, VCAM-1, and eNOS were higher in the cAVM group than in the control group, all the differences mentioned were statistically significant （P 〈 0,05）. Conclusions： VEGFR-2, MMP-9, VCAM-1, and eNOS are upregulated in patients with cAVM and might play important roles in angiogenesis, vascular remodeling, and migration in patients with cAVM. MMP-9, VEGFR-2, VCAM-1, and eNOS might be potential excellent group proteins in predicting the risk of cerebral hemorrhage at arteriovenous malformation.

Photoactive complexes of nonprecious transition metals, mainly including those in the first-row and partially the second-row of the Periodic table of elements, have received increasing attention in view of their low cost and long-term sustainability. They are recognized as promising alternatives to noble transition metal complex congeners that have been extensively studied in optoelectronic devices, artificial photosynthesis, photocatalysis, biodiagnostics, and therapeutics, etc. This review is devoted to a comprehensive summary on the classical and recent advances on photoactive nonprecious transition metal complexes, including photoactive Zr, V, Cr, Mo, and W complexes, Mn complexes and hybrids, Fe, Co, Ni, and Cu complexes, and Zn and Cd complexes and hybrids. A particular focus is given on the molecular design, modulation of photophysical and photochemical properties, and applications of the representative and lately-developed nonprecious metal complexes. In addition, a perspective on the future development in this field is provided at the end of this review.
