Objective To investigate the clinical value of the plasma N-terminal pro-brain natriuretic peptide levels in patients with acute cardiac dyspnea or noncardiac dyspnea.Methods 93 patients with acute dyspnea were divided into two groups:cardiac dyspnea group(61 cases)and noncardiac dyspnea group(32 cases).In cardiac dyspnea group,according to the results of echocardiography,the cases were divided into three groups:pure diastolic heart failure(25 cases),pure systolic heart failure(21 cases)as well as diastolic and systolic heart failure(15 cases).At the same time,heart function was classified according to NYHA.The plasma NT-proBNP level was measured by ELISA.The data was analyzed by SPSS12.0.Results The plasma NT-proBNP level of the cases with cardiac dyspnea and noncardiac dyspnea was(3.591 ?2.943)ng/L and(0.429 ?0.119)ng/L respectively.There was a significant difference between cardiac dyspnea cases and noncardiac dyspnea cases(P

This paper is aimed to study the differences of allelopathic effects of Panax notoginseng under different allelopathic chemicals resources and selection of appropriate rotation crops. The additive main effects and multiplicative interaction ( AMMI) model had been used to evaluate the stability of allelopathic effects of P. notoginseng on the varieties of corn, wheat and rice properly. The model could use not only to evaluate the stability of non-regional trial data but also explore the interaction between the rotation crop genotypes and donor substances more efficiently. Meanwhile, correspondence analysis can be used in the AMMI to evaluate genotype stability and donor substances. Ejingza No. 1 (g6) had stronger allelopathic effects with high stability, but Yunrui No. 1 (g9) which was appropriate rotation crop genotype, had weaker allelopathic effects with high stability. These findings will aid in choosing appropriate rotation crops and establishing proper rotation system.

Objective To discuss the surgical treatment for huge hepatoblastoma in children,and the technique of hepatectomy without blockade of the blood supply to the remained liver lobes.Methods We reviewed 12 cases of huge hepatoblastorna who had been operated from July 2001 to January 2009 in our hospital.The mean age of the children was 3.2 years(range,11 months to 12 years).The diameter of the tumor was from 10 to 23 cm.3～7 cycles of chemotherapy was routinely administrated before operation.When the tumor reduced to a certain size that radical resection could be performed safely,regular hepatectomy was conducted.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes was performed in every patient.Results The operations were successfully accomplished in all the 12 children.5 cases received right trihepatectomy (segment Ⅳ,Ⅴ～Ⅷ),4 cases received right hemihepatectomy(segment Ⅴ～Ⅷ),and the other 3 cases received Ⅳ,Ⅶ,Ⅷ segmentectomy,right Ⅴ,Ⅵ segmentectomy,and left hemihepatectomy respectively.The intraoperative hemodynamic parameters were stable,and there was no perioperative mortality.Postoperative chemotherapy wag routinely administrated.The follow-up period varied from 2 to 92 months.11 children survived and were disease free,among those 6 children have survived for more than 5 years.One child had brain and lung metastasis 5 months post operation,and died 7 months post operation. Conclusion Preoperative chemotherapy administrated to children with huge hepatoblastoma can reduce the tumor size and render tumor reseetable.Hepatoblastoma resection without blocking the blood supply to the remained liver lobes is a safe and feasible surgical technique.

Objective To investigate the mechanism of effects of acitretin on the treatment of psoriasis. Methods The expression of vascular endothelial growth factor (VEGF) and micro-vascular density (MVD) were detected by immunohistochemical technique before and after treatment with acitretin in 32 patients with psoriasis. Serum level of VEGF was measured by double antibody sandwich enzyme-linked immunosorbent assay (ELISA). Results The expression of VEGF protein and MVD were significantly higher in psoriatic lesions before treatment with acitretin than those after treatment (P

Objective To explore the effective therapeutic methods for hepatolithiasis.Methods We retrospectively analyzed the clinical material of 178 hepatolithiasis patients who underwent surgical therapy.Among the 178 patients,107 patients were treated with T-tube drainage(including 7 patients with left hepatic lobe or quadlrate lobe resection),and 71 patients were treated with bile duct-intestinal anastomosis(including 11 patients with left hepatic lobe or quadrate lobe resection).Results Recurrence rate of postoperative angiocholitis in the two groups was 49.5 % and 24 % respectively,and the reoperation rate was 28.7 % and 8 % respectively.Conclusions The key to prevent recurrent angiocholitis and reduce the reoperation rate is to relieve biliary tract stricture,remove the focus of infection and provide unobstructed bile duct drainage.

Object To optimize the preparation procedure for Zhixuan Granula (ZXG). Methods The optimum extracting conditions of ZXG were selected by orthogonal test with the active components: 23-acetate alisol B, atractylenolide I, and dried extract as the index, it mice sedation of ZXG was clarified by pharmacodynamics. Results The optimum preparation procedure was as follows: Rhizoma Alismatis and Rhizoma Atractylodis Macrocephalae were extracted with alcohol first, adding 12-fold 70% alcohol by refluxing, extracting twice, 2 h once, then extracted with water, adding 14-fold water, extracting twice, 2 h once. The extract showed the obvious effect on sedation of mice. Conclusion The optimum preparation procedure is reliable, with higher extracting ratio of the active components.

Objective To set up the molecular cytobiological model of endogenous coagulation factor Ⅷ (FⅧ) re-expressing in human liver cells L02,and to study the regulation pathway and molecular basis of the re-expression of FⅧ in L02 cells activated by NO signal.Methods The L02 cells at logarithm growth phase were selected and randomly divided into blank control group and experimental group, inhibitor group and inhibitor control group;they were cultured for 0,12,24,36,48,and 60 h.Flow cytometry was used to detect the expression of human FⅧ protein in L02 cells after treated for 48 h.Griess experiment was performed to detect the levels of NO in L02 cells at different time points;the transcription levels of human FⅧ gene,iNOS gene,NF-κB1 gene and I-κB alpha gene were detected by RT-PCR method.Western blotting method was used to detect the expression levels of human phosphorylated I-kappaB (phosphorylated I-κB)in L02 cells.Results The results of flow cytometry showed that the expression of human L02 FⅧ protein was found after treated with L-arginine for 48 h. The Griess results showed that the levels of NO in L02 cells in experimental group were significantly increased at 3,6,12,and 24 h (P<0.05)and the levels of NO in blank control group,inhibitor group and inhibitor control group had no changes. The RT-PCR results showed that the transcription of human FⅧ mRNA in L02 cells was found in experimental group,but there was no transcription of human FⅧ mRNA in blank control group,inhibitor group and inhibitor control group;the transcription levels of iNOS,NF-κB1 and I-κB alphain experiment group were increased(P<0.05)and the transcription levels of these genes in blank control group,inhibitor group and inhibitor control group had no changes. The Western blotting results showed that after adding L-arginine the expression level of phosphorylated I-κB was significantly increased (P < 0.05 ), other groups had no such change. Conclusion L-arginine can activate the phosphorylation of I-κB by NO signal pathway to lead to the changes in the expression of human FⅧ gene promoter upstream regulatory-related transcription factors NF-κB to activate the expression of human FⅧ in human liver cells L02.
