Objective To explore the clinical feature and therapeutic strategy for children with thrombotic microangiopathy (TMA). Methods The clinical manifestation, auxiliary examination and treatment of 24 cases of children with TMA was analyzed retrospectively. Hemolysis urine toxin syndrome (HUS)occurred in 22 cases, and thrombotic thrombocytopenic purpura (TTP) occurred 2 cases. Results Sixteen cases was onset from May to July,and 8 cases was onset from September to November. Typical HUS (D+HUS) was 8 cases, and atypical HUS (D-HUS) was 14 cases. In 22 HUS children, 18 cases were given hemodialysis or peritoneal dialysis treatment. The illness were significantly improved, and the platelet count and renal function fully recovered normal. But 1 case appeared neurological symptoms such as headache, facial paralysis on one side, gastrointestinal bleeding, and fever, after getting better. Eventually the patient died of disseminated intravascular coagulation. Two cases of TTP were given plasma exchange , anti-infection, large dose of methylprednisolone and anti- platelet aggregation treatment . After treatment, the level of hemoglobin and blood platelets returned normal and consciousness was recuperated. Conclusions HUS and TTP are similar in pathogenesis and clinical manifestation,and it is necessary to be differentiated. Early diagnosis and proper treatment is the key to save the life of children with TMA. As soon as the diagnosis is clear, hemodialysis or peritoneal dialysis treatment should be given to HUS, and plasma exchange to TTP,to quickly control the condition and improve the clinical symptoms.

AIM: To select optimum purification of Qingluotongbi decoction (Caulis Sinomenii etc.). METHODS: Qingluotongbi decoction was refined respectively by ceramic membrane microfiltration, ultrafiltration, alcohol sedimentation, high speed centrifugalization, flocculation and macroporous resin absorption. Their refining effect was compared according to indexes of color, clarity, loss rate of sinomenine, removal ratio of impurity. RESULTS: All kinds of purification made decoction light and clear. Removal ratio of impurity by macroporous resin absorption was the highest and reached 80% or more. Removal ratio of impurity by ceramic membrane microfiltration was 21.17% , less than that by alcohol sedimentation or ultrafiltration, but more than that by flocculation and centrifugalization. Loss rate of sinomenine by AB 8 type macroporous resin absorption was the lowest and reached 6.39% , and that by ceramic membrane microfiltration was 15.31% , less than that by ultrafiltration, alcohol sedimentation, centrifugalization and flocculation. The chromatogram of decoction disposed by macroporous resin was different from that of decoction unsettled, but that disposed by ceramic membrane was similar to that of decoction unsettled. CONCLUSION: The technique of ceramic membrane microfiltration is optimum purification of Qingluotongbi decoction with the virtues of moderate removal ratio of impurity, small amount lose rate of sinomenine and simple process.

Objective To investigate the effects of dexamethasone on expressions of epithelial neutrophil activating protein-78 (ENA-78) and transforming growth factor- beta 1 (TGF-β1) in neutrophil of asthma rats.Methods Thirty male SD rats were randomly divided into three groups on average, including asthma group, control group and dexamethasone treated group. In this experiment, the rat model of asthma were established by sentization and challenge with ovalbumin. Blood neutrophil were isolated and purified. The expression of ENA-78 was detected by flow cytometry. The expression of TGF-β1 was detected by immunohistochemical method in blood neutrophil and bronchial wall. Results Expression of ENA-78 in blood neutrophil in dexamethasone treated group(71.82 ±8. 87 mean fluorescence intensity)was lower than that in asthma group, but higher than that in control group(all P <0. 01). And expressions of TGF-β1 protein in dexamethasone treated group(0. 173 ± 0. 014,0. 202 ± 0. 019 optical density, respectively) was lower than that in asthma group(all P <0. 01) ,but higher than that in control group(all P <0. 01). There were significant positive correlation between ENA-78 expression at blood neutrophil and numbers of total inflammation cells in bronchoalveolar lavage fluid (n = 29, γ = 0. 762, P < 0. 01). Conclusion The beneficial effect of glucocorticoid(dexamethasone) on airway inflammation in asthma rats could be at least in part due to their direct inhibitory effect on ENA-78 and TGF-β1 protein generation by neutrophil.
