Objective To investigate Helicobacter pylori(Hp)infection and HLA-DQA1 allelic frequency in family members of children with recurrent abdominal pain.Methods One hundred and eighteen family members of 20 children with recurrent abdominal pain were divided into two groups:with and without recurrent abdominal pain.Serum Hp antibody was tested by dot immunogold filtration assay and immunophenotyping was determined by Western blot(immunobiot)technique.Polymerase chain reactionsequence specific primers(PCR-SSP)technique Was applied to identify HLA-DQAi allelic frequencies.Hardy-Weinberg equilibrium test was performed(P>0.05),and Chi-square test was used to compare the frequency of HLA-DQA1 alleles between the groups.Results The Hp seropositive rate in 118 members Was 100%and the Hp immunophenotyping was 96.6%.The prevalence of Hp Ⅰ and Ⅱ type was 55.1%(65/118)and41.5%(49/118).HLA-DQA1*0302 allelic frequency Was significantly higher in subjects with recurrent abdominal pain than that in subjects without one(23%vs.2%,X2=13.277,P=0.000).Conclusion There is immunogenetic difference between familial members with and without recurrent abdominal pain infected by Hp,and HLA-DQA1*0302 may be the associated gene contributing to different clinical outcomes after Hp infections.

Objective To investigate the effects of transcatheter arterial chemoembolization(TACE) on the expression of nm23, tissue inhibitor of metalloproteinase-2 (TIMP-2) and extrahepatic metastasis in hepatocellular carcinoma (HCC). Methods The specimens were collected from resectable HCC in 72 patients. Patients were divided into two groups. In one group, TACE was performed before tumor resection (Group A, n=36). In another group, the tumors were resected directly without preoperative TACE (Group B, n=36). The expression and distribution of nm23, TIMP-2 in the tumor tissue and liver parenchyma in the two groups were compared. All patients were followed up for 24 months,and the incidence of extrahepatic metastasis was compared between the two groups. Chi-square test was applied to compare the expression levels of nm23-H1 and TIMP-2. Results The number of cases of strong, moderate and no expression of nm23 were 24, 6 and 6 cases in group A respectively, and were 9, 6 and 21 cases in group B. Statistical differences were found between the two groups(X~2=15.52, P<0.01). The number of cases of strong, moderate and no expression of TIMP-2 were 21,3 and 12 cases in group A respectively, and were 9, 9 and 18 cases in group B. Statistical differences were demonstrated between them (X~2=9.00, P<0.05). There were 13 cases in group A and 15 cases in group B being diagnosed to have extrahepatic metastasis within 24- month period of follow up, but there was no significant difference between the two groups(X~2= 0.23, P>0.05). Conclusions TACE could enhance the expression of nm23-H1 and TIMP-2 in tumor tissues. Therefore, the potential of metastasis of tumor cells might be prohibited by TACE.

Objective To evaluate the efficacy of first-line CHOP or CHOP-like regimen on patients with advanced staged angioimmunoblastic T-cell lymphoma (AITL).Methods Between Aug 2006 and Sep 2014,twenty-nine AITL patients who were newly diagnosed without prior treatment were included in study.The clinical features,efficacy and survival were analyzed retrospectively.Results Median age of these patients was 59 years old.All patients had stage Ⅲ/Ⅳ disease.17 (58.6 %) cases presented with B symptoms.26 (89.7 %) cases had an international prognostic index (IPI) score ≥2,and 20 (69.0 %) cases had elevated LDH,9 (31.0 %) cases had ≥2 extranodal involvements.The median follow-up time was 20 months.Overall response rate was 69.0 % (20/29).Five (17.2 %) patients achieved complete remission (CR+CRu),15 (51.7 %) patients achieved partial remission,and 3 (10.3 %) patients had stable disease (SD),6 (20.7 %) patients had progressive diseases(PD).Median progression-free survival (PFS) was 6 months.1-and 2-year PFS rates were 39.0 % and 20.0 %.1-,2-and 5-year overall survival (OS) rates for all patients were 76.8 %,53.4 % and 17.1%,respectively.PFS was significantly better in chemotherapy-sensitive patients (P < 0.001).The responses to chemotherapy had a tendency of affecting the OS,but it failed to reach statistical significance (P > 0.05).Conclusions The CHOP or CHOP-like regimen maybe induce unfavorable efficacy in AITL patients.Further therapeutic options are required to improve the outcome.

OBJECTIVETo elucidate the effect of angiotensin II (AngII) on the expression of tissue factor (TF) by monocytes and its mechanisms.
METHODSMonocytes were isolated from healthy volunteers by Ficoll-Hypaque gradient and Percoll, and cultured in RPMI-1640. Procoagulant activity (PCA) was determined by one-stage clotting method, TF antigen by ELISA. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the TF gene mRNA. The levels of IkappaBalpha was detected by Western blot. Electrophoretic mobility shift assays (EMSA) were performed to evaluate the activity of NF-kappaB.
RESULTSAngII (10(-9) - 10(-7) mol/L) significantly increased monocyte PCA, TF antigen and TF mRNA expression in a dose and time dependent manner. Losartan (10(-6) - 10(-5) mol/L) significantly inhibited the effects of AngII on TF activity, antigen and mRNA expression in a dose-dependent effects. Staurosporine (2.5 x 10(-7) mol/L) and genistein (4 x 10(-5) mol/L) lowered TF level of monocytes (P < 0.05). Western blot analysis revealed that after exposure to AngII (10(-7) mol/L), IkappaBalpha level decreased at 15 min, reached nadir at 60 min, and recovered at 180 min. EMSA showed NF-kappaB binding activity increased at 15 min, reached peak at 60 min, and recovered at 180 min. Pyrrolidine dithiocarbamate (PDTC, 10(-4) mol/L), an inhibitor of NF-kappaB, or AT1R antagonist losartan (10(-5)mol/L) inhibited AngII-induced NF-kappaB translocation.
CONCLUSIONSAngII could induce the expression of TF in human monocytes, and this effect was mediated by AT1R. The PKC pathway played the most important role in AngII-induced TF expression. The activation of NF-kappaB was involved in TF expression in monocytes.

To study the effect of pulchinenoside (PULC) on the Frizzled (FZD) expression of adjuvant arthritis ( AA) rats. AA rats were prepared through the toe injection with complete Freund's adjuvant to culture fibroblast-like synoviocytes (FLS). The effect of the oral administration with PULC on the FZD8 expression was detected by the real time qPCR. The effect of FZD8 knockout on the expressions of IL-1, IL-6, IL-8 were detected by MTT and ELISA. The role of miR-375 in the abnomal expression of FZD8 was detected by the real time qPCR. The results showed signfiicant decrease in the FZD8 expression among AA rats, FLS proliferation ater FZD8 knockout and IL-1, IL-6, IL-8 expressions and notable increase in miR-375 expression after the oral administration with PULC. The up-regulated miR-375 expression can inhibit the FZD8 expression. PULC may inhibit the FZD8 expression by up-regulating the miR-375 expression.

In order to investigate the prevalence and track genetic and antigenic evolutions of infectious bronchitis virus (IBV) and their prevalence in Guangxi, China since 1985, gene amplification and sequencing and virus neutralization (VN) test on chicken embryo tracheal organ cultures were used in genotyping and serotyping of 28 IBV isolates during 2009-2011 in Guangxi. The results of N gene sequencing and comparison showed that the 28 isolates and reference strains were classified into three groups, and most isolates belonged to group Ill, while the isolates in 1985-2008 belonged to groups IV and II. The data of VN test indicated that the 28 isolates belonged to 6 serotypes; among them, 71. 4% belonged to serotypes 1, 2, and 3, and 11 (39.3%) shared the same serotype with the current vaccine strains. Given the data of our previous study, it is found that prevalent serotypes and their proportions varied in different areas of Guangxi and during different periods. These data lay a good foundation for developing an oil-emulsified inactivated polyvalent vaccine containing local dominant serotypes for the effective prevention and control of infectious bronchitis.
