Objective:To study the clinical and pathologic features of patients with lupus nephritis (LN) whose myeloperoxidase anti-neutrophil cytoplasmic antibody (MPO-ANCA) were positive. Methods:The clinical and pathological features were analyzed in 18 patients with LN whose MPO-ANCA were positive. And the data of patients with different clinical outcomes were compared. Results:(1)The hematological abnormalities, hypertension and serositis in these patients were more common than general ones with LN. (2)Proteinuria and hematuria were common, the morbidities of gross hematuria and renal failure in these patients were higher than general ones with LN.(3)Various autoantibodies were positive in these patients.(4)Segmental necrosis crescentic nephritis accompanied by density of immunocomplex in glomeruli and vasculitis in intestitium were common.(5)The morbidity of ESRF and mortality of these patients were similar to general ones with LN. The morbidity of tubular atrophy in those with poor prognosis was significantly higher than those survived. Conclusion:The patients with LN whose MPO-ANCA are positive have some difference from those with negative MPO-ANCA, but positive MPO-ANCA is not directly related to the prognosis.

OBJECTIVE To investigate the anti- tremor effect and mechanism of baicalein on oxotremorine- induced muscle tremor in mice. METHODS The acute model of muscular tremor was induced by intraperitoneal injection of oxotremorine, and the latency, duration and frequency of muscle tremor in mice were measured immediately; the saliva of mice was measured to reflect the correlation between tremor and peripheral nerve function; the aim of this study was to determine the content of MDA and the activity of GSH-PX, and to investigate the anti-oxidation of mice with tremor model. The activity of acetylcholinesterase (AchE) and acetylcholine transferase (ChAT) can indirectly reflect the level of acetylcholine in the brain. The level of monoamine neurotransmitters in brain tissue was determined by high performance liquid chromatography (HPLC-ECD). RESULTS The animals in the model group appeared obvious tremoring, salivating and erecting and other symptoms. Compared to the model group, there was no obvious inhibitory effect on the administration of each dose. After 7, 14, 21 and 28 d of continuous administration, the latency, duration and tremor frequency of tremor mice were significantly shortened, the levels of acetylcholine were significantly decreased, the changes of DOPAC and DA neurotransmitters in the brain of model group were recovered, regulate the dynamic balance of acetylcholine and dopamine in the brain. CONCLUSION Long- term administration can improve the tremor behavior of mice, the mechanismmay be related to the regulation of neurotransmittersin brain.
