The freshmen column in 39 985 Projectacademic libraries was investigated , which showed that 15 out of the 39 985 Projectacademic libraries have established freshmen column on their library website .Its posi-tion, contents and forms were analyzed.The typical freshmen column in libraries of Qinghua University, Shanghai Jiaotong University , and Sun Yat-sen University was described with suggestions put forward for improvement of its position, contents and forms.

Objective To investigate the feature brain damage and clinical manifestations in neuromyelitis optica (NMO) patients; To investigate the relationship between serum NMO-IgG antibody and NMO brain damage. Methods Clinical data of 37 NMO patients and their head and spinal cord MRI by 1.5T superconducting MR scanner, were analyzed; serum NMO-IgG antibody were measured by immunofluorescence. Results 17 cases were found to have abnormal signals on MRI, which were mainly in the white matter, pons, medulla, ventricle, aqueduct, and around the corpus callosum; According to pathological changes, brain damage can be divided into scattered irregularity (13 cases), fusion (3 cases),multiple sclerosis-like (1 case) ,with scattered irregularity more common,5 cases had clinical manifestations of brain damage: somnolence, vomiting, diplopia, visual rotation, 11 cases patients with brainstem damage show positive serum NMO-IgG antibodies. Conclusions Brain damage can be seen in half of NMO patients, they often located in the high expression area of AQP4: brain white matter, periventricular,brainstem and so on. Clinical symptoms has nothing to do with the size of lesions but the location, they often occur when brainstem was involved. Serum NMO-IgG is helpful in differentiating NMO with brain damage and MS.

Objective To discuss the diagnosis and treatment of non-specific ureteritis. Methods Considered by the Court left pelvis area occupying one case, and there are special non-specific symptoms in patients with treatment ureteritis recalled while literature and discuss the effective non-specific ureteritis diagnosis and treatment. Results Surgery did not undergo resection of the left kidney ureter, only stripping, removal of parcels renal pelvis, ureter choco-late-like substance. Conclusion Patients with a lower back pain, clinical history of macroscopic haematuria, imag-ingstudies revealed hydronephrosis, renal pelvis and ureter wall thickening, irregular, or beaded change, ureteral peri-stalsis is poor, should be carefully and spontaneous perirenal hemorrhage, ureteral cancer identification, If by related tests, imaging examination and cytological examination failed to diagnose patients, feasible with bilateral renal pelvis ureter surgical exploration, avoid blindly kidney ureteral resection.
