ObjectiveTo observe the effect of enema with Chinese medicine Changduqing combined with plasma exchange for treatment of endotoxemia in patients with acute-on-chronic liver failure.Methods A prospective randomized controlled trial was conducted, and 68 patients with acute-on-chronic hepatic failure who were hospitalized from January 2009 to June 2012 in the First Affiliated Hospital of Henan University of Traditional Chinese Medicine were randomly divided into treatment and control groups, 34 cases in each group. The patients in control group were treated with plasma exchange combined with western medicine comprehensive treatment such as protecting liver, reducing enzyme, removing jaundice, and in cases with hepatitis B, antiviral therapy was added. The treatment in patients of treatment group was the same as that in the control group, but additionally Changduqing enema of TCM decoction was given(ingredients: radix et rhizoma ginseng 10 g, flos magnolia officinalis 6 g, radix et rhizoma rhei 6 g, fructus aurantii immaturus 6 g, radix paeoniae rubra 10 g),twice a day combined with 3-4 times of plasma exchange treatment, once every 72 hours. The course of treatment of both groups was 4 weeks. The changes of total bilirubin (TBil), alanine aminotransferase(ALT), albumin(ALB), prothrombin activity(PTA), endotoxin, the improvement of clinical symptoms and signs such as lacking in strength, poor appetite, abdominal distension, oliguria, bleeding tendency, hepatic encephalopathy, infection and ascites were observed before and after treatment, and the survival rate in 24 weeks of follow-up was also investigated.Results Before treatment, the comparisons of TBil,ALT, ALB and PTA between the two groups were of no statistically significant differences(allP>0.05); compared with those before treatment, the levels of TBil and ALT were obviously decreased, and PTA was markedly increased after treatment in both groups, the degree of change being more prominent in treatment group〔TBil(μmol/L): 89.6±52.3 vs. 124.6±64.4, ALT(U/L):52.4±32.1 vs. 98.3±42.5, PTA:(53.8±11.5)% vs.(41.2±10.2)%, allP<0.05〕. The ALB levelsbefore and after treatment of both groups showed no significant difference(bothP>0.05). After treatment, the endotoxin(kU/L) in both groups were decreased in inchoate, developing and fully-developed stages and the descent being more significant in treatment group(inchoate stage: 0.094±0.015 vs. 0.109±0.032, developingstage: 0.102±0.019 vs. 0.146±0.062, fully-developed stage: 0.124±0.022 vs. 0.196±0.074, allP<0.05). The 24-week survival rates of developing and fully-developed stages in patients of both groups were lower than the rate in patients of inchoate stage, and the rates of treatment group in inchoate and developing stages were remarkably higher than the rate in control group〔inchoate stage: 94.1%(16/17) vs. 83.3%(15/18), developed stage: 85.7%(12/14) vs. 42.9%(6/14),bothP<0.01〕.ConclusionEnema with TCM Changduqing combined with plasma exchange for treatment of patients with acute-on-chronic liver failure can remove bilirubin, ameliorate endotoxemia, elevate PTA level and increase the survival rate of patients in 24 weeks of follow-up.

OBJECTIVETo investigate the clinicopathological characteristics, diagnosis and treatment of primary testicular yolk sac tumor (YST).

METHODSWe studied 8 cases of primary testicular YST by microscopy and immunohistochemistry.

RESULTSThe 8 cases of primary testicular YST, including 2 consultation cases, were confirmed from 1998 to 2013, accounting for 10.7% (8/75) of all the testicular germ cell tumors diagnosed in our hospital. The patients ranged in age from 7 to 43 years, 23.9 years on average. The main clinical manifestation of the patients was painless unilateral testis swelling. Microscopically, reticular tissues, schiller-duvaI (S-D) bodies, and eosin-stain transparent bodies were seen in the tumors. One of the cases was confirmed to be simple YST, while the other 7 mixed YST. AFP was a characteristic immunophenotype marker of the tumors.

CONCLUSIONPrimary testicular YST is a rare malignancyr with poor prognosis. Its diagnosis depends on preoperative AFP test and postoperative pathology. Comprehensive treatment, including orchiectomy, chemotherapy, and radiotherapy, can prolong the survival of the patients.

The purpose of this study is to explore the feasibility of wheat germ agglutinin (WGA) modified liposome as a vehicle for ophthalmic administration. Liposome loaded with 5-carboxyfluorescein (FAM) was prepared by lipid film hydration method. WGA was thiolated and then conjugated to the surface of the liposome via polyethylene glycol linker to constitute the WGA-modified and FAM-loaded liposome (WGA-LS/FAM). The amount of thiol groups on each WGA molecule was determined, and the bioactivity of WGA was estimated after it was modified to the surface of liposome. The physical and chemical features of the WGA-modified liposome were characterized and the ocular bioadhesive performance was evaluated in rats. The result showed that each thiolated WGA molecule was conjugated with 1.32 thiol groups. WGA-LS/FAM had a mean size of (97.40 +/- 1.39) nm, with a polydispersity index of 0.23 +/- 0.01. The entrapment efficacy of FAM was about (2.95 +/- 0.21)%, and only 4% of FAM leaked out of the liposome in 24 h. Erythrocyte agglutination test indicated that after modification WGA preserved the binding activity to glycoprotein. The in vivo ocular elimination of WGA-LS/FAM fitted first-order kinetics, and the elimination rate was significantly slower than that of the unmodified liposome, demonstrating WGA-modified liposome is bioadhesive and suitable for ophthalmic administration.

Immuno-fluorescence technique can qualitatively determine certain nuclear translocation, of which NF-κB/ p65 implicates the activation of NF-κB signal pathways. Immuno-fluorescence analysis software with independent property rights is able to quantitatively analyze dynamic location of NF-κB/p65 by computing relative fluorescence units in nuclei and cytoplasm. We verified the quantitative analysis by Western Blot. When we applied the software to analysis of nuclear translocation in lipopolysaccharide (LPS) induced (0. 5 h, 1 h, 2 h, 4 h) primary human umbilical vein endothelial cells (HUVECs) , we found that nuclear translocation peak showed up at 2h as with calculated Western blot verification results, indicating that the inventive immuno-fluorescence analysis software can be applied to the quantitative analysis of immuno-fluorescence.

OBJECTIVETo explore the expression change of stem cell-derived neural stem/progenitor cell supporting factor (SDNSF) gene in the injuried spinal cord tissues of rats, and the relation between the expressions of SDNSF and nestin.

METHODSThe spinal cord contusion model of rat was established according to Allen's falling strike method. The expression of SDNSF was studied by RT-PCR and in situ hybridization (ISH), and the expression of nestin was detected by immunochemistry.

RESULTSRT-PCR revealed that SDNSF mRNA was upregulated on day 4 after injury, peaked on day 8-12, and decreased to the sham operation level on day 16. ISH revealed that SDNSF mRNA was mainly expressed in the gray matter cells, probably neurons, of spinal cord. The immunohistochemistry showed that accompanied with SDNSF mRNA upregulation, the nestin-positive cells showed erupted roots, migrated peripherad and proliferation on the 8-day slice. However, the distribution pattern of these new cells was different from that of SDNSF-positive cells.

CONCLUSION(1) SDNSF is expressed in the gray matter of spinal cord. The expression of SDNSF mRNA in the spinal cord varies with injured time. (2) The nestin-positive cells proliferate accompanied with spinal cord injury repair, but do not secrete SDNSF.

Objective To explore the immunophenotype of children with acute myeloid leukemia(AML) and its clinical significance.Methods Statistics was used to analyze the relationship between the immunophenotype of AML and their French-American-Britain(FAB) classification,complete remission (CR) in one month and 3-years event-free survival(EFS).Results CR rate was 71.6% and 3-years EFS rate was 50.8%. HLA-DR and CD34 absent mainly in M3, associated with higher CR and EFS rate. So did CD33 negative cases, especially in M2. CD13 positive was significantly predictive factor for achieving CR.Co-expression of lymphoid antigens and NK cell antigens(CD56) with M2 which correlated with lower CR and EFS rate.Conclusions The negative of HLA-DR, CD34, CD33,as well as CD13 positive, have relationship with good prognosis. Lymphoid antigens and CD56 are poor prognostic factors.
