Objective To investigate the state of Th1/Th2 cytokine imbalance in patients with lupus nephritis (LN) and its role in the pathogenesis. Methods Plasma level of interleukin-18 and interleukin-13 in 18 patients with active LN and 16 normal controls were measured by enzyme-linked immunoadsordent assay (ELISA). IL-18 and IL-13 expression in the renal tissues from 18 patients and 6 normal renal tissues were also detected by immunohistochemical assay. The ratio of plasma and renal IL-18/IL-13 was then calculated. Results Plasma levels and renal expression of IL-13 and IL-18 in patients with LN were increased significantly compared to those of normal controls (P0.05). The ratio of renal IL-18/IL-13 was not significantly different among all types of LN and normal controls. The ratio of plasma IL-18/IL-13 was positively correlated with LN renal tissue activity index (AI), but no correlationship could be found in renal IL-18/IL-13 ratio. Conclusion It seems that the immune disturbance in systemic lupus erythematosus (SLE) can not be simply divided into Th1 predominant and Th2 predominant. It seems far complicated than this Th1/Th2 paradigm. It may be affected by the state of disease activity, the lesion location and the type of pathology.

Objective The person's Mesangial Proliferative Glomemlonephritis (MsPGN) were divided into 3 types based on clini- cal manifestations: nephroticsyndrome, hematuria and proteinuria. To investigate the expression of CD11a, CD11b, CD62L and its signifi- cance in the kidneys patients with MsPGN. Methods CD11a, CD11b and CD62L expression in blood of MsPGN patients (n=35) were investigated by flow eytometry method, and the changes of these proteins in kidney were surveyed. Results In MsPGN, CD11a and CD11b expression in blood were significandy lower and CD62L expression in blood were markedly higher than that in normal humans. And the renal glomeruli of MsPGN also expressed CD11a, CD11b and CD62L. Conclusion The expression of CD11a, CD11b and CD62L are abnormal in MsPGN, and apoptosis may play certain role in the pathogenesis of MsPGN.

Objective To explore the clinical manifestations, electroencephalographic characteristics and therapeutic effect of drugs in children with Jeavons syndrome. Methods The clinical and electroencephalographic characteristics and thera-peutic effect of drugs were analyzed in 4 children with Jeavons syndrome. Results Among the four children there were 3 female and 1 male. The age at the onset of the disease was from 1 to 6 years. The typical clinical manifestations of this disease were brief, fast and repeated eyelid myoclonia (EM) with or without absence seizure. The typical electroencephalography (EEG) in two patients showed 3-6 Hz generalized spike and waves and polyspikes burst, and the eye closure and intermittent photic stimu-lation helped to induce discharges and clinical events. The typictal EEG in the other two patients showed 3.0-3.5 Hz generalizedδslow wave rhythm burst. The drugs of choice for treatment was sodium valproate monotherapy in two cases, levetiracetam in one case, sodium valproate combined with levetiracetam in one case. During the follow-up, seizures were controlled in one case, decreased in frequency in two cases and were still frequent in one case. Conclusions Jeavons syndrome is one of the idiopathic and generalized epileptic syndromes and characterized by EM with or without absence seizure. Video EEG monitoring plays an important role in the diagnosis of this disease. Sodium valproate and levetiracetam were effective for this disease.

Purpose To investigate the clinical pathological features, pathological diagnosis and differential diagnosis of the non-Wilms’ renal tumors in children. Methods The clinical pathological data and immunohistochemical findings of 15 cases of non-Wilms’ renal tumors were retrospectively analyzed with review of the relevant literature. Results In 7/15 (46. 67%) cases of cystic nephroma ( CN) , microscopically the variable size of cysts were lined by a single layer flattened, cuboidal epithelia, separated by fi-broblastic stroma;in 4/15 (26. 67%) cases of rhabdoid tumor of kidney (RTK), histological characteristics were rhabdoid cells and cytoplasmic inclusions;in 2/15 (13. 33%) cases of clear cell sarcoma (CCSK), the classical pattern of histology demonstrated nests, cords of ovoid epithelioid or spindled clear cells separated by fibrovascular septa, which had a marked ’ chicken wire’ pattern of small blood vessels;in 1/15 (6. 67%) case of congenital mesoblastic nephroma (CMN), the tumor was mainly composed of spindle cells arranged in fascicular pattern, in which fetal renal tissue was seen;in 1/15 (6. 67%) case of granularity renal cell carcinoma, micro-scopically, the cancer cells with eosinophilic granular cytoplasm arranged in nests, cords and tubular pattern. Conclusions Although non-Wilms’ renal tumors is a small part of all kidney tumor, it is difficult to diagnose and distinguish from other tumors before opera-tion. The pathological diagnosis is the most reliable method for differential diagnosis of non-Wilms’ renal tumor.
