Objective:To explore the effect of glycynhizinatis on serum IgE level of rat model and patients with asthma.Methods:Trie rats were divided into four groups randomly: normal control, asthmatic model, model treated with GL, model treated with DS. The rats were sensitized and challenged with ovalbumin to establish an asthmatic model. The established models were measured by breathing curves, pathological changes in pulmonary tissue slices and the level of serum IgE. Furthermore, serum IgE level of patients with asthma was also detected. Results: High amplitude of breathing curve and fast rhythm were showed in group of asthmatic model, there were more inflammatary cells infiltration in the tiny bronchial wall, hyperplasia of cup-shaped cells and thicker smooth muscle in the pulmonary tissue slices. Compared with normal control, the level of serum IgE in model group increased obviously. The rats treated with glycyrrhizinatis showed low amplitude of breathing curve, decreasing inflammatary cells infiltration in pulmonary tissue slices of tiny bronchial wall, no hyperplasia of cup-shaped cells, and decreased serum IgE level. There were no significant difference between the groups of GL and DS. At the same time, the serum IgE level in patients with asthma was observed. The results showed that the level of serum IgE was higher in patients with asthma than that in normal control (P

Objective To evaluate the value of surface shaded reconstruction (SSD) of CT scanning on developmental dysplasia of the hip (DDH). Methods Unilateral DDH in 39 cases was examined with Picker 2000S spiral CT to perform SSD of the affected pelvis. All patients were females with the age ranging from 3.5 to 8 years old (average 4.25 years). Of 39 cases, 22 cases were complete dislocation the hip, 17 cases were subluxation of the hip. The measurement on SSD included of the depth and surface area of normal and affected acetabulum; the distances from the lowest point of the bottom of the acetabulum (O point) to the anterior end (A point) of the lateral margin of anterior acetabular column (OA), the middle point (B point) of the acetabular roof (OB) and the posterior end (C point) of lateral margin of the posterior acetabular column (OC). Results In normal hip, the medial and lateral margin of the acetabular roof was overlapping, and in DDH, a bony defect was found in the lateral acetabular margin in three-dimensional CT scanning. The depth of the dysplastic hip with subluxation and the normal hip was (21.25?1.25)mm and (23.89?1.56)mm respectively with significant difference(P
