Objective To study the clinical characteristics and outcome of cytomegalovirus(CMV) infection in infants.Methods All data including time of infection,clinical characteristics,laboratory tests and outcome of CMV infections in hospitalized infants were collec-(ted) and analyzed from January,1994 to July,2004.Results In 87 infected infants,congenitally infected newborns,perinatal infection in infants and postnatal infection in infants accounted for 27.6%,62.0%,16.6%,respectively.CMV hepatitis was the most frequent type of disease with the incidence of 41.3%,in which the incidence of splenomegaly was 10.3%.Most of CMV hepatitis infants had a good prognosis with the improved rate 80.5%.Central nervous system abnormality(including abnormal intension of muscle,convulsion,ocular and hearing abnormalities) occurred only in congenital and perinatal infection with the incidence of 20.4%.Generalized infection,the incidence of congenital infection and perinatal infection was 16.7%,1.8%,respectively.It did not occur in postnatal infection.The mortality rate of congenital infection and perinatal infection were 12.5% and 1.85%,respectively.Conclusions CMV infection is the main cause of infant hepatitis and it can also cause neurologic sequelae.The outcome of generalized infection in congenital infection is bad and the mortality rate is high.

According to the theory of in vitro radioassay, using TSHAb as binder and 125I-staphylococcal protein A (125I-SPA) as tracer agent, a new method for detecting the abnormal immunoglobulin (aIgG) in the sera of patients with Graves disease (GD) was reported. In the initial study of the method, the most appropriate interacting conditions of TSHAb with aIgG were explored and compared with ELISA using ganglioside (GLS) as a binder. The relationship between aIgG and thyroid-stimulating imunoglobulin(TSI) was probed into. The results showed that TSHAb could interact specifically with aIgG in vitro; but it could not interact with IgG from sera of normal subjects, systemic lupus erythematosis (SLE) patients and diabetic patients. With aIgG as an evaluating index, the mean value in 29 normal subjects was 1. 06?0. 17. When the sera of 72 patients with GD in different clinical stages were studied, the aIgG index was positive in 83% of untreated GD patients (n = 24), in 12% of GD patients in clinical remission (n = 25) and in 82% of relapsed GD patients (n = 23). Very significant difference was observed between normal subjets and untreated and relapsed patients with GD (P

Objective:To find small molecular leads for inhibition on early stage of HIV infection by identification and characterization of the HIV-1 gp41 C-helix mimotopes.Methods:For identification of the gp41 C-helix mimotopes,C7C phage display peptide library was biopanning by using a synthetic peptide N36 which was derived from the gp41 N-helix as target.After three rounds of screening,positive phage clones were identified by ELISA and sequenced.Results:16 of 26 phage clones were identified to bind with peptide N36,and 10 of them were sequenced.Every clone of ten clones contains at least two hydrophobic residues,which may dock into the hydrophobic pocket in the gp41 N-helix domain.9 of the 10 clones have a conservative sequence WW,which may mimic the W628 and W631 in C-helix to interact with the hydrophobic residues in the gp41 pocket.One clone expressing the conservative sequence named clone No.8(CYWWHRLHC) was selected for characterization.The binding between the clone No.8 and N36 was blocked by free peptide N36.And the binding between clone No.8 and peptide N36 was inhibited by peptide C34(IC 50=12.5 ?g/ml).Conclusion:The short circular peptides displayed on phages containing WW residues may mimic the conformational epitope of the HIV-1 gp41 C-helix to interact with the N-helix.This information may be useful for design of HIV-1 fusion inhibitors.

OBJECTIVETo observe clinical effect of integrated Chinese medical (CM) treatment (as maintenance therapy) on the progression-free survival (PFS) and overall survival (OS) in patients with advanced non-small-cell lung cancer (NSCLC) after first-line chemotherapy.
METHODSThe study was a prospective, randomized, controlled clinical trial. Totally 69 non-progressive advanced NSCLC patients treated with first-line chemotherapy were randomly assigned to the test group (34 cases) and the control group (35 cases). Patients in the control group were treated with one Western drug chemotherapy (Gemcitabine or Alimta or docetaxel). Those in the test group were treated with integrated CM treatment (CM decoction, CM Intravenous preparation, and point application). Each cycle consisted of 21 days. Treatment lasted till the disease progressed, or intolerable toxic/adverse reactions occurred, or patients refused to continue the treatment. Patients' life spans were regularly followed-up.
RESULTS(1) The median cycle of maintenance therapy was 2 cycles for two groups with no statistical difference (P =0.274). The median PFS was 12.43 weeks in the test group and 10.00 weeks in the control group, showing statistical difference (P =0.025). The middle survival time (MST) was 18.8 months in the test group and 16.73 months in the control group, showing no statistical difference (P =0.437).
CONCLUSIONCM treatment (as maintenance therapy) showed quail effect to one Western drug chemotherapy in prolonging patients' life span.

Objective To study the effects of nuclear factor-?B(NF-?B)decoy oligodeoxynucleotide(ODN)on the preeclamptic umbilical serum induced expression of precollagen Ⅰ,Ⅲ mRNA and tumor necrosis factor-?(TNF-?)in cultured human umbilical artery smooth muscle cells (HUASMC).Methods Primary cultured HUASMC of normal pregnancy were divided into four groups: group A(HUASMC were incubated with umbilical serum of normal pregnancy);group B(HUASMC were incubated with umbilical serum of preeclampsia);group C(HUASMC were transfected with NF-?B cis decoy ODN 48 h before incubation with umbilical serum of preeclampsia);group D(HUASMC were transfected with NF-?B scramble ODN 24 h before incubation with umbilical serum of preeclampsia).NF-?B cis decoy ODN and NF-?B scramble ODN were transfected with cationic lipofectamine to the latter two groups,respectively.The proliferation of human umbilical artery smooth muscle cells was evaluated by methyl thiazolyl tetrazolium and the apoptosis was analyzed by flow cytometry.The expression levels of precollagen Ⅰ,Ⅲ mRNA were detected by RT-PCR,the expression levels of TNF-? were detected by western blot.Results(1)The proliferation of group B(0.19?0.02)and group D(0.18?0.03)was significantly increased as compared with those of group A(0.11?0.02)and group C(0.14?20.02)(P0.05).(5)The expression of TNF-? of group B(0.74?0.11),group C(0.36?0.09)and group D(0.79?0.12)were significantly higher than that of group A(0.15?0.03)(P0.05).Conclusions NF-?B cis decoy ODN could down-regulate the proliferation,as well as the expression levels of precollagen and TNF-? of HUASMC induced by umbilical serum of preeclampsia.NF-?B may play an important role in the pathogenesis of placental artery abnormalities in preeclampsia.

Objective To explore the effect of chemokine CXCL12 and its receptor CXCR4 on proliferation,migration and invasion of epithelial ovarian cancer cells.Methods CXCR4 and CXCL12 mRNA and protein expression of human ovarian cancer cell line CAOV3 was detected by RT-PCR and immunocytochemistry.Integrin ?1 and vascular endothelial growth factor-C(VEGF-C)mRNA expression were detected in CAOV3 cells stimulated by CXCL12.The CAOV3 cells were divided into 6 groups:control group(un-stimulated),experimental group 1(stimulated by 100 ng/ml CXCL12),experimental group 2 (stimulated by 10 ng/ml CXCL12),experimental group 3(100 ng/ml CXCL12 and 10 ?g/ml neutralizing CXCR4 antibody),experimental group 4(100 ng/ml CXCL12 and 1 ?g/ml CXCR4 antagonist AMD3100),experimental group 5(10 ?g/ml neutralizing CXCR4 antibody or ascites).Methyl thiazolyl tetrazolium(MTT)was used to analyze the effects of different concentrations of CXCL12 on CAOV3 cell proliferation.Transwell invasion chamber and reconstructed basement membrane(Matrigel)were used to evaluate effect of various concentrations of CXCL12 and ascites on CAOV3 cell migration and invasion. Results CAOV3 cells expressed CXCR4 mRNA(0.70?0.10)and protein,but did not express CXCL12 mRNA or protein.Immunostaining of CXCR4 was mainly located in cytoplasm.CXCR4 mRNA was up- regulated after 100 ng/ml CXCL12 stimulation(1.24?0.14;t=-7.1088,P=0.0021).Integrin ?1 mRNA was greatly increased at 3 hours by stimulation of 100 ng/ml CXCL12(before and after stimulation 0.53?0.10,1.53?0.16;P0.05).Experimental group 1 stimulated the migration and invasion of CAOV3 cells in chemotaxis assay compared with control group and experimental group 2(number of cell migration respectively 523.3?25.2,108.0?7.2,211.7 ?24.7,number of cell invasion respectively 39.3?4.0,4.0?1.0,15.7?3.1;P
