Objective:To observe the changes of visual evoked potential(VEP)in diabetic rats and the influence of nerve growth factor(NGF)and aminoguanidine(AG)on VEP.Methods:Diabetes was induced in adult male Wistar rats with streptozotocin(STZ).Rats were divided into normal control group(CON),diabetes model group(DM).NGF-treated group(D +N)and AG-treated group(D+A).VEP was measured during the 3~(rd)month,6~(th)month,9~(th)month,and 12~(th)month.Results: Compared with the CON group,all rest groups had longer latencies and lower amplitudes(P

Objective To report specific clinico-radiological syndromes in neuropsychiatric systemic lupus erythematosus (NPSLE).Methods Ten patients with NPSLE in Peking Union Medical College Hospital from 2005 to 2011 were studied retrospectively with magnetic resonance imaging, computer tomography or positron emission tomography. Results Posterior reversible encephalopathy syndrome was diagnosed in 2 patients with radiological features,headache and tonic-clonic seizure;3 patients with bilateral diffuse leukoencephalopathy,cognitive disorder and acute confusional state; 1 Fahr' s disease patient,with cognitive disorder and psychiatric symptom,movement disorder; 2 Parkinsonism patients with tremor and cogwheel rigidity,and 2 chorea patients. Conclusions The emergence of diffuse brain calcinosis,leukoencephalopathy and edema may happen in lupus encephalopathy particularly.Autoantibody reaction and vascular disease may play an important role in movement disorder including Parkinsonism and chorea.

ObjectiveTo investigate the clinical and pathological characteristics of dermatomyositis with muscular perifascicular atrophy (PFA).MethodsA series of 104 consecutive patients clinically and pathologically diagnosed as dermatomyositis by muscle biopsy in our laboratory from December,2003 to August,2011,were enrolled in this study. Muscle biopsy of all the enrolled patients had shown PFA of muscle fibers.ResultsAmong the 104 patients,34 were males and 70 were females with a mean age of 45 years old.Among them,8 cases had normal electromyogram;42 had normal serum creatine kinase level;11 were diagnosed as carcinoma;75 were found to be combined with interstitial lung disease (ILD).Based on morphologic changes of muscle biopsy,they were divided into pure PFA group with 54 cases and PFA plus focal damage group with 50 cases.Compared with the pure PFA group,there was prominent mononuclear cell infiltration into perimysial intermediate sized vessels and membrane attack complement (MAC) deposition in the intramuscular capillaries in the PFA plus group.Skin biopsy had been taken in 12 cases together with muscle biopsy and had shown the border effectof both PFA and interface dermatitis in muscle and skin.ConclusionsOur study suggests that chronic immune vascular damage and insufficiency in dermatomyositis may cause ischemia and focal myofiber damage in watershed regions. The incidence of ILD in our dermatomyositis patients with PFA is high.

Objective To investigate the level of serum free fatty acid (FFA )after improving the life style in patients with coronary heart disease complicated metabolic syndrome and the effect of therapeutic life style on traditional risk factors of coronary artery disease.Methods A total of 395 patients with coronary heart disease complicated metabolic syndrome were recruited.Pa-tients were divided into intervention group (group A,conventional drug therapy+ intensive life style intervention,n=97)and non-intervention group (group B,conventional drug therapy,n=38)according to the scores of life style.Serum free fatty acid (FFA) was determined by ELASA.The scores of life style was obtained bylife style questionnaire.Results (1)The serum FFA of pa-tients with coronary heart disease complicated metabolic syndrome were positively related to waist circumference and waist-high-ra-tio.(2)Waist circumference,BMI and FFA of group A were significantly lower than those in group B after therapeutic life style in-tervention(P <0.05).(3)Compared with the baseline,the constitution index and FFA in group A were significantly lower after 6-months therapeutic life style intervention(P <0.05).Conclusion Therapeutic life style can reduce the level of FFA and constitution index of the patients with coronary heart disease complicated metabolic syndrome.

Objective To study the effect of glucocorticoid on serum interleukin(IL)-1,IL-6,transforming growth factor-?_1(TGF-?_1) and tumor necrosis factor alpha(TNF-?) in children with primary nephrotic syndrome(PNS).Methods The levels of cytokines on serum were compared in 3 different patho-type,and IL-1,IL-6,TGF-?_1 and TNF-? in serum were detected using enzyme-linked immunosorbent assay(ELISA) in 25 children with PNS before and after treatment with glucocorticoids.Results Significant difference of IL-1,IL-6,TGF-?_1 and TNF-? were found between the two group before and after the treatment(P0.05).The level of TGF-?_1 in MCD was lo-wer than that in MsPNG,FSGS before and after the treatment(P0.05),and the level of it in FSGS was higher than that in MsPNG after the treatment(P
