Objective To explore the effect of diammonium glycyrrhizinate(DG) and astragalus membranaceus (AM) injection on the clinical comprehensive score in patients with acute lung injury (ALI). Methods According to the random number table method,a prospective random controlled study was conducted in which 60 cases of patients with ALI were divided into a study group and a control group(each,30 cases). Both groups received a comprehensive treatment based on the new guidelines,and the study group was additionally given DG and AM injection(DG 150 mg+AM 20 ml)one time per day for 7 days. The scores of lung injury,acute physiology and chronic health evaluationⅡ(APACHEⅡ)and systemic inflammatory response syndrome(SIRS)were measured at baseline,3rd and 7th day after treatment,and ventilation support time and final disease mortality rate were also calculated in all the patients. Results There were no statistically significant differences between the two groups in the scores of lung injury,APACHEⅡand SIRS before treatment and after treatment for 3 days(all P>0.05),with prolonged treatment,the above indexes were significantly reduced compared with those before treatment in the two groups,and the decreases in scores of indexes in study group was more significant than those in control group after treatment(lung injury score:1.31±0.99 vs. 2.29±1.08,APACHEⅡscore:18.43±8.17 vs. 24.23±6.98,SIRS score:1.69±0.89 vs. 2.60±1.04,all P<0.01). The time(hour)for ventilator support in study group was shorter than that in the control group(176.10±57.81 vs. 286.07 ± 156.27,P<0.01),but there was no statistically significant difference in mortality rate between the two groups(13.33%vs.16.67%,P>0.05). Conclusion The results suggest that DG and AM injection improve the scores of lung injury,APACHEⅡand SIRS,and alleviate the lung injury,so that the injection is beneficial to the early weaning from the ventilator to support treatment in patients with acute lung injury,and has certain therapeutic effect on ALI.

Objective To investigate the expression and distribution of plasmacytoid dendritic cells(pDC) in peripheral blood and renal tissues in children with Henoch-SchSnlein purpura(HSP),and explore the role of pDCs in the pathogenesis of Henoch-Schtnlein purpura nephritis(HSPN).Methods Among the 40 children with HSP,28 cases were in the active phase(renal biopsy performed in 8 cases of them) and the other 12 in remission phase.Peripheral blood mononuclear cells were isolated,and the expression of pDC was detected by flow cytometry.The normal control group was established (n =15).Total RNA of peripheral blood was extracted and transcripted into cDNA.Sybr green dye based real-time quantitative PCR method was used to compare the expression(indicated as 2-△Ct value) of CXC motif chemokine 10 (CXCL10),CC chemokine ligand 5 (CCL5),chemokine CXC subfamily receptor 3 (CXCR3),CC chemokine receptor 5 (CCR5) in children with HSP and those in the controls.Immunohistochemistry labeling technique was used to detect the distribution of pDC in renal tissues from renal biopsy,and the normal controls were established (n =3).Results The expression percentage of pDC in peripheral blood in active phase was 0.051 ± 0.039,significantly lower than those in remission phase (0.181 ± 0.082) and the normal controls (0.166 ± 0.079) (P ＜ 0.000 1).Chemokines genes CXCL10 and CCL5 were overexpressed in peripheral blood ceils of acute phase HSP children,but chemokine receptors CXCR3,CCR5 were lowly expressed compared with normal controls.There was almost no expression of pDC in the normal control renal tissues,while pDC was infiltrated in glomeruli of HSPN children.Conclusions The number of pDC and chemokines' expression in peripheral blood is abnormal,and the pathogenesis of nephritis may be involved with the pDC in peripheral blood to migrate to the renal tissues.

Objective: To explore the relationship between serum levels of immunoglobulin E (IgE) and calciifc aortic valve disease (CAVD) in relevant patients.
Methods: A total of 394 patients were enrolled in our study. Based on echocardiography presentation, the patients were divided into 2 groups: CAVD group,n=169 and Non-CAVD group,n=225. Serum levels of IgE were examined by chemiluminescence method. The IgE levels were compared between 2 groups and the relationship between serum IgE level and CAVD was analyzed.
Results: Serum levels of IgE in CAVD group was significantly higher than Non-CAVD group 113.30 IU/ml vs 63.76 IU/ml (P<0.05); multivariate logistic regression analysis conifrmed above difference (P<0.05) and it also indicated that the alteration of surum IgE level is obviously related to CAVD occurrence.
Conclusion: Serum IgE level is obviously increased in CAVD patients. IgE is an independent biochemical indicator of CAVD, it may play the important role in CAVD pathogenesis.

OBJECTIVETo develop a method for preparing a decellularized scaffold based on human liver tissue.

METHODSA surgical specimen of the left lateral lobe of the liver was obtained from a patients with hepatic hemangioma. The decellularization process was performed by repeated freezing-thawing, sequential perfusion with 0.01% SDS, 0.1% SDS and 1% Triton X-100 through the portal vein, and sterilization with peracetic acid. L-02 cells were then engrafted onto the decellularized liver scaffold.

RESULTSHE staining, DAPI staining and scanning electron microscopy all verified the absence of residual cellular components in the decellularized scaffold. The residual DNA content in the decellularized scaffolds was 25.3∓14.6 ng/mg (dry weight), which was less than 1% of the total DNA content in a fresh human liver. Immunohistochemistry demonstrated that type I and IV collagens, fibronectin and elastin were all retained in the scaffold. The engrafted L-02 cells survived well on the scaffold with active proliferation and expressed albumin and G6pc.

CONCLUSIONIt is feasible to prepare decellularized scaffolds using surgical specimens of human liver, which can be a new approach to constructing a tissue-engineered liver for clinical purposes.

OBJECTIVETo investigate the effect of Biejiajian Pills on the expressions of the signal molecules and target genes of Wnt signal pathway in HepG2 cells and explore the mechanisms by which Biejiajian pills suppress the invasiveness of hepatocellular carcinoma.

METHODSHepG2 cells were cultured for 48 h in the presence of serum collected from rats fed with Biejiajian Pills. The expressions of β-catenin, GSK-3β and P-GSK-3β in the cultured cells were assessed by Western blotting and the expressions of CD44v6 and VEGF were detected using immunohistochemistry.

RESULTSHepG2 cells cultured with the serum of rats fed with Biejiajian Pills showed lowered expressions of β-catenin protein both in the cytoplasm and the nuclei with also inhibition of phosphorylation of GSK-3β and reduced expression of CD44v6 and VEGF.

CONCLUSIONBiejiajian Pills can significantly reduce the expression of β-catenin by decreasing the phosphorylation of GSK-3β and blocking the Wnt/β-catenin signaling pathway to cause down-regulation of the target genes CD44v6 and VEGF, which may be one of the molecular mechanisms by which Biejiajian Pills suppress the proliferation and invasiveness of hepatocellular carcinoma.
