Objective To investigate the expressions and significance of p21 protein and K-ras protein in congenital biliary dilatation(CBD),and their relationship.Methods Surgical specimens of CBD were obtained during operation on 36 children from Jan.2000 to Sep.2007.Nine normal bile ducts specimens from miscarried fetus and children's corpse.The specimens were fixed in 40 g?L-1 formalin and embeded by paraffin,slice-fixed.SP immunohistochemical method was used to detect the expressions of p21 protein and K-ras protein.Results The positive rate of K-ras protein was 13.8% in CBD,which was significantly higher than that in normal bile duct tissues.The positive rate of p21 protein was 55.6% in CBD,and 100% in normal bile duct tissues.p21 protein positive expression rate in CBD was significantly lower than that in normal bile duct tissues(P

Objective: To observe the expression of Toll-interacting protein (Tollip) in appendix and analyze its significance during acute inflammation. Methods: Thirty-three patients with acute appendicitis were included in the present study and 6 subjects with non-inflammatory appendixes were taken as controls (without inflammatory changes). The pulse rate, body temperature (BT), white blood cell (WBC) count and neutrophil (NEUT) count were observed one hour before appendectomy. Based on H-E staining and pathological examination, the appendix samples were divided into four groups : non-inflammatory appendix (A), simple appendicitis (B), suppurative appendicitis (C) and gangrenous appendicitis (D). The expression of Tollip protein (the localization, qualitative and semiquantitative analysis) was analyzed using immunohistochemistry and digital image analysis. The correlation of Tollip with pusle rate, BT, WBC and NEUT was also analyzed. Results: Significant differences in BT, WBC and NEUT were found between different pathological groups (P<0. 05). Tollip protein was mainly expressed in the epithelium mucosa and glandular epithelium of appendix, but was not detected in the neutrophils. During the development of appendiceal inflammation (non-inflammatory appendix to simple appendicitis, to suppurative appendicitis, then to gangrenous appendicitis), the expression of Tollip protein gradually increased and was significantly correlated with WBC (P<0. 05). Conclusion: During the development and progression of acute appendicitis, Tollip expression is up-regulated in appendix tissues and is closely correlated with systemic responses of inflammation, such as the increase of WBC.

By using ~3H—TdR incorporation and CTLL—2 cell line,we observed effects of RU486,anantagonist of type Ⅱ glucocorticoid receptor,on dexamethasone inhibition of lymphocyte prolifer-ation and interleukin—2(IL—2)production in rat spleen.It was shown that RU486 obviouslyantagonized the inhibitory actions of dexamethasone on lymphocyte proliferation and IL—2 pro-duction.By means of dot hybridization and Northern blot analysis,effects of dexamethasone andRU486 on IL—2 gene expression were investigated in lymphocytes of rat spleen.The datademonstrated that dexamethasone markedly decreased IL—2 mRNA production,RU486 alonedidn't affect IL-2 mRNA levels,but obviously reversed dexamethasone-mediated downregala-tion of IL—2 mRNA production in ConA—activated lymphocytes.These results suggest thatthe above effects of dexamethasone may be mediated by glucocorticoid receptor in lymphocytesof rat spleen.

OBJECTIVETo probe a better therapy for chronic persistent asthma.

METHODSThirty-six cases of chronic persistent asthma were randomly divided into a beat-sensitive moxibustion group (17 cases) and a western medication group (19 cases). In heat-sensitive moxibustion group, the sensitization points between Feishu (BL 13) and Geshu (BL 17) were selected with heat-sensitive moxibustion; in western medication group, Seretide inhalant was applied. The patients of both groups were continuously treated for 3 months and the therapeutic effects were evaluated by clinical symptom scores and pulmonary ventilation function test.

RESULTSAfter treatment, the effective rate of 88.2% (15/17) in heat-sensitive moxibustion group was superior to that of 47.4% (9/19) in western medication group (P < 0.05); the clinical symptom scores and pulmonary ventilation function were obviously improved in the two groups, and the heat-sensitive moxibustion group was superior to the western medication group (all P < 0.05).

CONCLUSIONFor chronic persistent bronchial asthma, heat-sensitive moxibustion can improve the clinical symptoms and the pulmonary ventilation function, and it is better than Seretide inhalant.

To investigate me material basis of Mahuang Fuzi Xixin decoction (MFXD) for anti-inflammation and immune-suppression based on the combined method of serum chemical and serum pharmacological. The LC-MS/MS fingerprints of MFXD, drug-containing serum and blank serum were compared to define the components in plasma. Histamine, β-hexosaminidase released from RBL-2H3 cell infulenced by drug-containing serum at different time points were measured by ELISA. The effect of drug-containing serum on lipopolysaccharide-induced splenocyte proliferation at different time points were determined by MTT. A correlation analysis was made on components of MFXD and pharmacological indexes based the stepwise regression method. After the intragastrical administration with MFXD, 32 components were discovered in rat serum, including 27 prototype components (10 from Mahuang, 13 from Fuzi and four from Xixin) and five unknown components. Compared with blank serum, drug-containing serum could reduce the release of histamine from RBL-2H3 induced by antigen at different time points (P < 0.05); except the 4-hour drug-containing serum, all of the remaining drug-containing serums could inhibit the RBL-2H3 mastocyte degranulation induced by antigen at different time points (P < 0.05). Drug-containing serum could significantly lipopolysaccharide-induced mouse splenocyte proliferation at 15 and 30 min (P < 0.05). A regression analysis was made on the chemical data of components absorbed into blood and pharmacological indexes, i. e. release rate of histamine, release rate of β-hexosaminidase and inhibition rate of splenocyte. This suggested the close correlations among methyl pseudo-ephedrine, pseudoephedrine and histamine released from RBL-2H3 induced by antigen; pseudoephedrine, hypaconine, methyl pseudoephedrine and β-hexosaminidase released from RBL-2H3 induced by antigen; as well as benzoyl hypaconine, benzoylaconine, 14-benzoyl-10-OH-mesaconine, mesaconine and lipopolysaccharide-induced mouse splenocyte proliferation. Methylpseudoephedrine, pseudoephedrine, benzoyl hypaconine, benzoylaconine and mesaconine may be part of material basis of MFXD on anti-inflammation and immune suppression.
