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.

Objective:To study the preventive and therapeutic effects of Jiechangyan Qixiao granule ( JQX) in the rats with ulcer-ative colitis ( UC) induced by dextran sulfate sodium .Methods:The UC model was induced by drinking dextran sulfate sodium ( DSS, 4%) freely in Wistar rats weighting 180-220g.Guben Yichang tablets and sulfasalazine was used as the standard drugs for the compari -son.After 7-day intragastric administration of Jiechangyan Qixiao granules at the dose of 2.70, 1.35 and 0.68 g· kg-1 · d-1 , the se-rum levels of malondialdehyde (MDA), superoxide dismutase (SOD), nitric oxide (NO), interleukin -6(IL-6)and tumor necrosis factor-α(TNF-α), and the protein expression of myeloperoxidase (MPO) and intercellular adhesion molecule (ICAM-1)in colon and nuclear factor(NF-kBp65) were detected.Results:Compared with the model group, the granule at high and medium dose could sig-nificantly increase the activity of SOD in blood and decrease the contents of MDA , TNF-αand IL-6 (P<0.05 or P<0.01).The granule could also notably decrease the MOP activity in colonic mucous of UC rats (P<0.05 or P<0.01), and the contents of NF-kBp65 and ICAM-1 in the inflammation reaction(P<0.01).Conclusion: JQX shows promising efficacy in the treatment of UC rats induced by dextran sulfate sodium .

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 therapeutic effects of Gengnian Anshu granule on the endocrine system of menopausal rats. Methods:The rats aged 13-15 months received intragastrical treatment with Gengnian Anshu granule at the doses of 1. 9,0. 95 and 0. 48 g·kg - 1 ·d - 1 for 6 weeks. At the end of treatment,serum and hypothalamic hormone levels were detected,and the organ indices including uterus and ovaries were determined. Results:In the menopausal rats,Gengnian Anshu granule could significantly in-crease the serum estradiol(E2 )(P < 0. 05 or P < 0. 01),decrease serum follicle-stimulating hormone(FSH)and luteotrophic hor-mone(LH)(P < 0. 05 or P < 0. 01),increase norepinephrine(NE),dopamine(DA),5-hydroxytryptamine(5-HT)and β-endor-phine(β-EP)(P < 0. 05),increase the number of cells positive for estrogen receptor(ER)protein expression in hypothalamus(P <0. 05 or P < 0. 01),and decrease the number of cells positive for gonadotropin-releasing hormone(GnRH)protein expression(P <0. 01). Conclusion:With a multi-target action mechanism and an integral regulatory role,Gengnian Anshu granule can provide favor-able regulation against endocrine disorder in menopausal rats.
