Objective To analyze MR imaging manifestations of spinal area lymphoma in order to improve the recognition and understanding of the disease. Methods A group of 45 patients with pathologically or clinically proven spinal area lymphoma were reviewed. Five cases were primary NHL,40 cases were secondary with 9 HL and 31 NHL (27 B-cell type NHL and 4 T-cell type NHL). MR Imaging findings were analyzed and correlated with clinical and pathologic findings. Results (1) Location of lesions: 13 cases were focal type and 32 cases were multifocal type. All of the 5 patients with primary lymphoma were focal type, while 32 of 40 cases of secondary lymphoma were multifocal type. (2) Type oflesions: ①Vertebral destruction: 27 cases manifested as bone destruction with 23 of them had soft tissuemass and the extent of soft tissue masses were larger than that of bone destruction in 18 cases.②Soft tissuemasses: 6 cases manifested as soft masses without obvious bone destruction, of which 5 cases had soft tissuemasses imbedded vertebrae and communicated paravertebral and epidural spaces through intervertebralforamen.③Bone marrow infiltration: 9 cases of secondary spinal lympboma had signal intensity changes ofbone marrow without obvious cortical bone destruction and soft tissue mass. ④ Spinal cord infiltration:3 cases of secondary spinal lymphoma had spinal cord swelling and signal intensity changes. (3) MRIfindings: all lesions of bone destruction and marrow infiltration manifested as hypointense on T1-weightedimages, hypointense, isointense or hyperintense on T2-weighted images and hyperintense on T2-weightedimages with fat-suppression technique. All soft tissue masses were homogeneous hypointense on T1-weightedimages and hyperintense on T2-weighted images. After intravenous injection of contrast media, the lesions ofthe bone and the soft tissue showed mild or moderate enhancement without remarkable cystic degenerationand necrosis. Conclusions Most of the spinal area lymphoma is the secondary B type NHL with complexMRI manifestation. Osteolytic lesion with contiguous paravertebral soft tissue mass imbedded vertebrae whichcommunicated paravertebral and epidural spaces through intervertebral foramen with a mild or moderateenhancement may suggest the diagnosis of this rare disease.

Objective To analyze the imaging manifestations of primary non-Hodgkin lymphoma of skeletal muscle and improve the recognition of this rare disease.Methods Five cases of primary non-Hodgkin lymphoma of skeletal muscle proved pathologically underwent imaging exam,including MRI and CT in 3 cases,only MRI in 1 case,only CT in 1 case,X-ray in 2 cases and bone scintigraphy in 2 cases.Results Diffuse enlargements of involved muscle with presentation of overall configuration were observed in all five cases.All 4 cases manifested as homogeneous soft masses,which is isoattenuating to normal muscle on unenhanced CT images.After intravenous injection of contrast media,the masses enhanced homogeneously and slightly(2 cases)or moderately(1 case)on CT images.The lesions were homogenous and had isointense or slightly low signal intensity compared with that of uninvolved muscle on T1-weighted images and high signal intensity on T2-weighted images.After intravenous injection of contrast media,all 2 cases enhanced homogeneously and moderately with the enhanced signal intensity of involved muscle greatly higher than that of uninvolved muscle on MR images.Two cases of X-ray plain showed no destruction of bone and 2 cases of bone scintigraphy exams showed increased radiotracer uptake of involved muscle with no infiltration of bone marrow.Conclusion There are several characteristics on the imaging of primary non-Hodgkin lymphoma of skeletal muscle.MRI is the optimal imaging method for the diagnosis of this disease.

Objective The inhibitory effects of avastin on new blood vessels in nonproliferation diabetic retinopathy, age-related macular degeneration and neovascular glaucoma have been demonstrated. But only seldom report of avastin on corneal neovascularization(CNV) was seen. Present study was to evaluate the effect of topical bevacizumab (avastin) on experimental corneal neovascularization in mice. Methods Thirty eyes of 30 Balb/c mice were chemically cauterized by applying a 2 mm-diameter filter paper soaked 1 mol/L NaOH solution at the central cornea for 40 s. All animals were randomly assigned to five groups, including 1 mg/mL, 3 mg/mL and 5 mg/mL bevacizumab eye drops group respectively, 1 mg/mL dexamethasone sodium phosphate eye drops group (positive control) and normal saline solution group (negative control) . The drug was topically utilized twice per day. CNV was examined under the slim lamp on the 3rd, 7th and 14th day after alkali burn. Animals were killed on the 14th day after alkali burn. Area of CNV was calculated in terms of pixels on digital photographs. The use of animals followed the Regulations for the Administration of Affair Concerning Experimental Animals by State Science and Technology Commission. Results No significant difference was found in the grade of corneal injury among five groups (F = 0. 201, P = 0. 935). The area of neovascularization at the cornea surface was (37.11 ±3.17)% in 1 mg/mL bevacizumab group, (29.75 ±3.56)% in 3 mg/mL bevacizumab group, (18. 76 ± 2. 55) % in 5 mg/mL bevacizumab group, (20. 91 ± 2. 75) % in dexamethasone group and (41. 65 ±2. 11)% in normal saline group, showing a significant difference among groups(F = 71. 687, P =0. 000) with the further comparative decline in 5 mg/mL bevacizumab group compared with other groups (P ＜ 0. 01) . Conclusion The topical use of bevacizumab (avastin) inhibits alkali burn-induced CNV in mice.

OBJECTIVE:To evaluate the effectiveness,safety and economy about Wenxin granules in the treatment of cardio-vascular diseases based on Meta-analysis. METHODS:Using“Wenxin granules”“Wenxinkeli”“Wenxin”as the search terms, searching PubMed,ProQuest,Springer,The Cochrane Library,CNKI,VIP and Wanfang data(Jan. 2000-Oct. 2015)through com-puter,relevant journals and conference papers by hand,randomized controlled trials about Wenxin granules in the treatment of car-diovascular diseases were screened and classified according to indications. Meta-analysis was performed by using RevMan 5.3 soft-ware,while cost-effectiveness analysis and minimum cost analysis were used for economic evaluation. RESULTS:Totally,38 liter-atures were involved,including 20 literatures of arhythmia,9 of premature ventricualr contraction,4 of coronary disease angina pectoris,3 of unstable angina pectoris,2 of pediatric viral myocarditis. Meta-analysis showed that compared with control drug, Wenxin granules showed better clinical efficacy for arrhythmia with less ADR;showed better clinical efficacy and ECG efficacy for premature ventricualr contraction with less ADR;showed better clinical efficacy for angina pectoris of coronary disease,unstable angina pectoris and pediatric viral myocarditis,with statistical significance (P<0.05). The incremental cost-effectiveness analysis showed that the additional cost of Wenxin granules in the treatment of above indications was worth it all,compared to control drug. Single factor sensitivity analysis supported the stability of results. CONCLUSIONS:Wenxin granules have a better effectiveness, safety and economy in the treatment of cardiovascular diseases,but still need high-quality evidence to support.

Objective To investigate the characteristics of cerebral vascular imaging and risk factors of stroke in popu?lation with family history of stroke in rural areas of Ji County, Tianjin. Methods The volunteers with family history of stroke were recruited in the study to undergo computed tomography and computed tomography angiography (CTA) of head as well as physical and laboratory examinations. A total of 281 subjects, including 153 male and 128 female, underwent exami?nation, and were divided into stroke group and non-stroke group. Results The detection rates were significantly higher in male subjects than those of female subjects, including smoking rate, drinking rate, educational level, and decreased level of high density lipoprotein cholesterol (HDL-C), whereas the detection rate of high level of triacylglycerol (TG) was significant?ly higher in female than that of male subjects (P<0.05). There were 38 subjects in stroke group. The age, internal carotid ar?tery calcification rate (ICAC) and internal carotid artery tortuosity (ICAT) rate were significantly higher in stroke group than those of non-stroke group (P<0.05) . The results of multivariate Logistic regression analysis indicated that age, hyperten?sion, ICAC, and ICAT were independent risk factors for stroke. Conclusion For population with family history of stroke, age, hypertension, ICAC and ICAT were risk factors of stroke.
