A patient diagnosed with myoepithelial carcinoma was recently treated in our department. The neoplasm was huge, located in the left maxillofacial region, blocking both eyes, impeding feeding. About one month before admission, the tumor began to bleed frequently, about 100 ml each time, causing headache, dizziness, fatigue, and cold sweats. CT showed the maximum diameter of the tumor was about 23 cm, with uneven density, and maxillofacial bone destruction. MRI revealed internal bleeding and necrosis inside the tumor. After admission, blood routine test showed erythrocyte count 3.64 x 10(12)/L(↓), hemoglobin 106 g/L(↓), hematocrit 0.320 (↓), serum iron 6.2 μmol/L(↓). After surgery, the patient recovered smoothly.

Objective To investigate the inhibitory effects of IBI302 on experimental choroidal neovascularization (CNV).Methods Affinity of IBI302 to vascular endothelial growth factor (VEGF) family cytokines (including VEGF-A165,VEGF-A121 and placental growth factor PlGF) and complements (C3b,C4b) was determined by enzyme-linked immunosorbent assay (ELISA).The antagonist effect of IBI302 on VEGF was measured by proliferation,migration and tube formation tests of human umbilical vein endothelial cells (HUVEC).The anti-complement activity of IBI302 was measured by hemolysis test mediated by complement classical pathway and alternative pathway.Rhesus laser-induced CNV model was divided into 5 groups including model control group,bevacizumab group,IBI302 0.25 mg group,IBI302 0.50 mg group and IBI302 1.25 mg group.Fluorescein angiography and optical coherence tomography were performed on these monkeys at 14 and 28 days after drug delivery to observe the fluorescein leakage area and retinal thickness.The aqueous VEGF concentration was measured at 29 days after drug delivery.Results IBI302 showed good affinity to VEGF-A165,VEGF-A121 and PlGF,as well as C3b and C4b.IBI302 significantly inhibited the proliferation,migration and tube formation of HUVEC induced by VEGF-A165.IBI302 inhibited the hemolysis induced by complements obviously.At 14 and 28 days after drug delivery,the area of fluorescein leakage and retinal thickness in IBI302 0.25 mg group,IBI302 0.50 mg group,IBI302 1.25 mg group were reduced.The differences of the area of fluorescein leakage and retinal thickness in three IBI302 groups were not significant (P＞0.05).At 29 days after drug delivery,the VEGF concentration in the aqueous of rhesus monkey in bevacizumab group [(38.644 ± 6.521) pg/ml] was decreased than that in model control group [(94.203± 17.360) pg/ml],the difference was significant (P＜ 0.05).The VEGF concentration in the aqueous of rhesus monkey in three IBI302 groups were less than 31.300 pg/ml.Conclusion IBI302 inhibited experimental CNV through blocking the activity of VEGF and complement.

Objective:To evaluate the hemodynamic situation of the patients with moyamoya disease using MR perfusion imaging,and to explore the relationship between compensatory collateral circulation and perfusion. Methods:Seventy-two hospitalized patients with moyamoya disease were selected as typical moyamoya disease group,including 37 males and 35 females,aged 10 - 62 years old,all patients underwent cerebral angiography (DSA)and MR perfusion imaging.And 20 patients with out neurological history were used as control group.With mean transit time (MTT)image as a standard,the abnormal perfusion ranges were classified as region of interest (ROI),and the corresponding perfusion parameter values,including cerebral blood flow (CBF),cerebral blood volume (CBV),MTT and time to peak (TTP)were recorded,respectively.The cerebellum was used as a reference in this study,the perfusion parameters were standardized,and the relative ratios of the perfusion parameters (rMTT,rTTP,rCBF,rCBV)were obtained.Results:Compared with control group,the rMTT and rTTP of the patients in typical moyamoya disease group were prolonged and the rCBF was reduced (P <0.05 or P < 0.01), but the rCBV had no obvious difference (P >0.05).②Compared with the contralateral side,the rMTT and rTTP of the suffered side were prolonged,and the rCBF and rCBV were reduced (P < 0.05 or P < 0.01).Compared with chronic onset group,the rCBV and rCBF of the patients in acute onset group were reduced (P <0.05 or P <0.01),but the rMTT and rTTP had no statistically significant difference (P > 0.05).There were no significant differences in all parameters between hemorrhagic moyamoya disease group and ischemia group (P > 0.05 ). Conclusion:MR perfusion imaging can accurately evaluate the hemodynamic condition of moyamoya disease;MTT and TTP hve higher sensitivities than CBF and CBV.MR perfusion imaging can evaluate the compensation of collateral circulation of moyamoya disease and provide the objective basis for the clinician to select the proper surgical timing and the best operation methods.
