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.

Objective To evaluate the effects of sevoflurane-remifentanil anesthesia on the balance between cerebral oxygen supply and demand during cerebral revascularization for ischemic moyamoya disease by monitoring regional cerebral O2 saturation (rSO2) with near infrared spectroscopy.Methods Forty patients of both sexes aged 19-59 yr with a body mass index of 19-25 kg/m2 undergoing superficial temporal artery-middle cerebral artery anastomosis were randomly allocated into 2 groups (n =20 each):propofol-remifentanil group (group PR) and sevoflurane-remifentanil group (group SR).Radial artery was cannulated for direct BP monitoring and blood sampling.Near infrared spectroscopy probe was placed on the forehead.Anesthesia was induced with propofol TCI (Cp =5 μg/ml),fentanyl 3 μg/kg and rocuronium 0.6 mg/kg.The patients were mechanically ventilated after tracheal intubation (VT 8-10 ml/kg,RR 10-12 bpm,I∶ E 1∶2,FiO2 =1.0).PETCO2 was maintained at 35-40 mm Hg.Anesthesia was maintained with sevoflurane (end-tidal concentration 1.0％-1.7 ％) or propofol TCI (Cp =3-4 μg/ml) in combination with remifentanil TCI (Cp =3.5 ng/ml) and intermittent iv boluses of rocuronium 0.3 mg/kg.BIS was maintained at 40-60 during operation.rSO2 was recorded before induction of anesthesia (T0),10 min before and 10 min after blood vessel was clamped (T1,T2) and 10 min after anastomosis was completed (T3).Results rSO2 was significantly increased on the operated side at T3 in PR group while in SR group bilateral rSO2 was significantly increased at T1-3 as compared with the baseline values at T0 (P ＜ 0.05 or 0.01).rSO2 on the operated side was significantly higher at T1 in group SR than in PR group (P ＜ 0.05).Conclusion The efficacy of sevoflurane-remifentanil anesthesia is similar to that of propofol-remifentanil anesthesia for revascularization for moyamoya disease in terms of maintence of the balance between cerebral oxygen supply and demand.

Objective To discuss the diagnostic value of MRI for portal vein(PV)and superior mesenteric venous(SMV)thrombosis.Methods Twelve patients with portal vein and superior mesenterie venous thrombosis proved by operation and pathology were examined with T_1WI,T_2WI,T_2-weighted fat suppression imaging,MR angiography(MRA)and Gd-DTPA enhanced dynamic MRI.Results Signals in PV and SMV were detected on T_1 WI and T2WI in 12 cases;3 acute thrombus presented hypo-or isointense on T_1 WI and hyperintense on T_2 WI.ttyperintense on T_1 WI and T_2WI were showed in 8 subacute thrombus; 1 chronic thrombus presented heterogenous intense on T_1W1 and hypointense on T_2W1.No enhancement within PV and SMV was found on Gd-DTPA enhanced images.Bowel dilatation was found in 10 cases,bowel hemorrhage in 6,bowel wall thickening in 12,intestinal pneumatosis in 3,ascites in 12,cavernous transformation of the portal vein in 3,hepatic perfusion disorder in 6.Conclusion MRI is an important and sensitive imaging method for the diagnosis and location of portal vein and superior mesenteric venous thrombosis with intestinal ischemia.
