A follow-up study of the dynamic changes with multiple parameters of blood coagulation and plasma limulus assay was carried out in 20 patients with decompen-sated hepatic cirrhosis.It was found that the levels of endotoxin in peripheral blood and factor VIII-related antigen increased significantly, prothrombin time and kaolin partial thromboplastin time prolonged, whereas fibrinogen, factor II, hepaplastin test, antithrombin-III and fibronectin decreased.Our data suggested that( 1 )both the coagulation abnormalities and endotoxemia were coexisted and correlated progressively with the disease process. ( 2 )the incidence and severity of endotoxemia were closely correlated with the degree and severity of hepatic decompensation; ( 3 )dynamic charges of endotoxemia and coagulation abnormalities were of some prognostic significance in decompensated hepatic cirrhosis

Objective:To study effect and mechanism of Anchang Yuyang Decoction with Jiawei Shengji Powder (ACYYD&JWSJP) on ulcerative colitis (UC) in rats. Methods: Ninety SD rats were divided randomly into six groups: normal control group,pathologic model control group,ACYYD group, JWSJP group, ACYYD & JWSJP group And Solfasalazine (SASP) treatment group. The model of ulcerative colitis were established by given 2,4,6-TNBS. After medication for 3 weeks, the parameters including colonic gross morphology, colon tissue injury scores, MPO activity, the content of IL-1?, IL-8, TNF-? and IL-10 were observed. Results: Inflammation relieving of colonic mucosa and ulcer healing were found in all treatment group rats at different degree. Colonic gross morphology, colon tissue injury scores,MPO activity and the level of IL-1?,IL-8, TNF-? decreased, while levels of IL-10 increased after therapy (P

Objective To explore the efficacy of duo positive airway pressure ventilation in treating preterm infant with neonatal respiratory distress syndrome (RDS). Methods 65 preterm infants admitted to the neonatal intensive care unit from December 2012 to December 2013 were randomly divided into DuoPAP group (34 cases) or NCPAP (31 cases) group. Blood gas analysis(pH value, PaO2, PaCO2 and OI) at 1h, 12h, 24h, and 72h, and incidence of apnea, pulmonary air leak, repeated application of pulmonary surfactant and non-invasive ventilation failure at 72h in the two groups were measured and compared after using intubate surfactant extubate (INSURE). Results OI after non-invasive ventilation at 1h, 12h, and 24h was signiifcantly higherin DuoPAP group than that in NCPAP group P<0.01). PaCO2 after non-invasive ventilation at 1h, 12h, 24hand 72h was signiifcantly lower in DuoPAP group than that in NCPAP group (P<0.01). PaO2 after non-invasive ventilation at 1h and 12h was higher in DuoPAP group than that in NCPAP group, and there was signiifcant difference between the two groups (P<0.01). The incidence of non-invasive ventilation failure, apnea in 72h was lower in DuoPAP group than that in NCPAP group, and there was signiifcant difference between the two groups (P<0.05). Conclusions Compared with NCPAP, DuoPAP is more feasible for improving oxygenation, decreasing the need for mechanical ventilation in 72h in preterm infants with neonatal RDS.

Objective:To investigate the plastic method of glottis carcinoma in surgery. Method:Retrospectly analyzed 29 patients with T_2 ,T_3 glottis carcinoma who admited in our department From 1996 to 2004. All of them were treated with the displacement of ventricular bands-epiglottis mucosal flap in the surgical management of glot-tis carcinoma. The tumour was primarily from vocal cords, and not exceeded 2cm. Result: All cases were success-fully renovated laryngeal cavity with the displacement of ventricular bands-epiglottis mucosal flap and followed up for 5 years after operation. Three years survival rate was 86.2% ,5 years survival rate was 78.9% ,and tube draw-ing rate was 100%. Conclusion: With this method, surgery would be simplified and the patients would keep the voiced function and swallowing function.

Objective To investigate the effect of rosiglitazone on p38 mitogen-activated protein kinase (p38MAPK) pathway in polycystic kidney cyst-lining epithelial cells. Methods The cyst-lining epithelial cells (PKD cells) from human polycystic kidney were treated with rosiglitazone (10 μmol/L), peroxisome proliferator-activated receptor-γ (PPARγ) inhibitor GW9662 (10 μmol/L), rosiglitazone (10 μmol/L) +GW9662 (10 μmol/L), p38MAPK specific inhibitor SB203580 (10 μmol/L), SB203580 (10 μmol/L)+ rosiglitazone(10 μmol/L) for 2 hours followed by epidermal growth factor (EGF) stimulation. Protein expressions of p38, phuspho-p38 (p-p38) and proliferating cell nuclear antigen (PCNA) were detected by Western blot. p38 mRNA was examined by RT-PCR. Expression of c-fos and c-jun was observed by immunocytochemistry. Results (1) EGF markedly up-regulated the expressions of p38, p-p38, PCNA, c-fos anti c-jun compared with control group (P<0.01). (2) Compared with EGF treated group, rosiglitazone significantly reduced p38 activation and mRNA expression (P<0.01, respectively). Rosiglitazone, rosiglitazone+SB203580 could significantly down-regulated p-p38, PCNA, c-fos and c-jun expression (P<0.01, respectively) with no significant difference between these two groups. (3) GW9662 partially reversed the reduction effect of rosiglitazone. Conclusions Rosiglitazone can inhibit proliferation of autosomal dominant polycystic kidney disease cyst-lining epithelial cells partially through down-regulating p38 activation and reducing c-fos, c-jun and PCNA expression. The above effect of rosiglitazone is in part PPARγ-independcnt.
