Tumor necrosis factor-related apoptosis inducing ligands (TRAILs) and their receptors can specifically express in hepatocellular carcinoma cells.TRAIL can specifically induce tumor cells apoptosis through death receptors (DRs) ; TRAIL combined radiation and chemotherapy can effectively overcome the TRAIL resistance of tumor cells,and promote the apoptosis of tumor cells,meanwhile the gene therapy of TRAIL on anti-tumor clinical treatment has been widely used.

Objective To investigate the effects of Zafirlukast on emotions and Th1/Th2 cytokines in asthmatic children.Methods One hundred and eight asthmatic children were randomly allocated to 3 groups.The children in group A inhaled Pulmicort aerosol 200 ?g twice every day.On the basis of inhaled Pulmicort aerosol,the children in group B took orally Zafirlukast orally 10 mg once every day.The children in group C only took orally Zafirlukast 10 mg once every day.The course of treatment of all children were 4 weeks.Anxiety,depression status and the levels of IFN-? and IL-4 in blood serum were respectively detected before and after treatment.Results Scores of anxiety and depression after treatment in 3 groups were significantly lower than those before treatment(Pa0.05).Conclusions Zafirlukast or Glucocorticoid inhalation has the same effect on improving emotional status and accommodating disequilibrium of Th1/Th2 for asthmatic children,but effect of Zafirlukast combined with Glucocorticoid inhalation are better.

Objective To explore the therapeutic effect of Yupingfeng powder in secondary immunodeficiency caused by simple nephrotic syndrome(SNS) in children.Methods Seventy-eight cases of SNS patients were divided into 2 groups randomly.One was control group which were treated with immunosuppressant only.The other group was Yupingfeng powder group which were treated with both immunosuppressant and Yupingfeng powder.The morbidity of infection,the relapse rate of SNS,and serum immunoglobulin IgA and IgG and the T-lymphocytes subtype were detected before and after treatment in two groups.Results The morbidity with infection was 55.3% in Yupingfeng powder group,which shows a remarkable decrease compared with control group(85%).The relapse rate of SNS was 39.5% in Yupingfeng powder group which was much lower than that in control group(67.5%).The level of serum IgA and IgG before treatment were(3.88?1.22) g/L and(0.83?0.14) g/L and rose up to(10.06?1.89) g/L and(1.38?0.10) g/L after treatment in Yupingfeng powder group.Whereas the control group with(6.23?1.55) g/L and(0.85?0.13) g/L was remarkably lower than those in Yupingfeng powder group.CD4+,CD8+ and the ratio of CD4+/CD8+ were(37.91?3.89)%,(30.69?3.08)% and(1.24?0.49)% respectively before treatment.They rose up to(42.38?4.89)%,(26.01?2.20)% and(1.63?0.41)% respectively in Yupingfeng powder group,while those in control group were(39.87?3.91)%,(29.76?3.55)% and(1.34?0.24)% respectively after treatment.Conclusion It is feasible to treat the Yupingfeng powder to cure the of secondary immunodeficiency caused by SNS in children.

ObjectiveTo investigate the characteristics of sexual behavior and HIV infections between normal men who have sex with men (MSM) and money boy (MB) in Jining city,so as to provide the basis for intervention.MethodsSentinel surveillance,VCT and respondent-driven sampling were adopted to recruit the target population,and the data was aualyzed with SPSS13.0.ResultsThe average age of normal MSM was 26.45 ± 5.8 and MB was 22.23 ± 3.3.The rates of single,marriaged and divorced about normal MSM and MB were 48.24％,45.53％,6.7％ and 85.4％,9.8％,4.9％ respectively.The educational level of normal MSM(74.8％ )was higher than that of MB(51.22％ ).MB group's rate of condom used(75.61％ ;51.22％ ) was higher than that of normal MSM ( 52.03 ％ ;32.79％ ).There was statistical significance in age,educational level,marital status and infecting rates of HIV between MB group and normal MSM group.ConclusionCompared with normal MSM,MB is the high risk population and bridge population of transmission of HIV.

Objective To explore the effect of fibroblast growth factor receptors 1-dominant negative strategy (FGFR1-DN) on alkaline phosphatase (ALP) activity of bone marrow stromal stem cells (BMSCs) after osteogenic induction.Methods BMSCs were transfected with eukaryotic expression plasmid pcDNA 3.1 (+)-DN FGFR1 and pcDNA3.1 (+)-FGFR1.The experiment was conducted in 4 groups:FGFR1-DN transfection group,FGFR1 transfection group,pcDNA3.1(+) empty vector transfection group and non-transfection group.The ALP activity of BMSCs was detected in logarithmic growth phase after osteogenic culture.The qualitative detection of ALP activity was carried out immunohistochemically while the quantitative detection by cALP kit.The ALP activity was compared between the 4 groups at 7 and 14 days after osteogenic induction.Results Compared with 7 days,the ALP activity at 14 days was significantly increased in the 4 groups,and the increase in FGFR1-DN transfection group was significantly higher than in the other 3 groups (P ＜ 0.05).At both 7 and 14 days,the ALP activity in FGFR1-DN transfection group was the highest while that in FGFR1 transfection group was the lowest (P ＜ 0.05).Conclusions FGFR1-DN can promote the ALP activity of BMSCs during osteogenesis.This may provide an experimental basis for the joint application of local gene therapy and tissue engineering and for construction of tissue engineered bone with better biocompatibility.

Primary tracheal tumor is an uncommon disease in clinical oncology .It tends to be misdiag-nosed in very early stage ,as well as lack of standards for staging and treatment nowdays .The main strategy for the treatment of primary tracheal tumors is surgical comprehensive treatments .But as the huge development of modern radiotherapy technology the past a few years ,radiotherapy could play more and more important roles in the treat-ment of tracheal tumors.Meanwhile,the application of tracheal scaffold have provided the patients with tracheal tumors some new choices on the treatments .Yet,there are no guildline for the standard of the surgery ,the dose of the radiotherapy and the definition for the tumor target volumes .Here,we give a review on the latest process and research on the treatment of primary tracheal tumors .

OBJECTIVE:To explore the effects of levothyroxine on the follicular helper T lymphocyte level of patients with Hashimoto's thyroiditis. METHODS:51 patients with Hashimoto's thyroiditis were selected as levothyroxine group,and another 30 healthy people were control group. Levothyroxine group was orally given 25-50 ug Levothyroxine sodium tablet,once a day,the dose was adjusted based on thyroid function,and the dose maintained when thyroid function turned normal,for continuous 90 d. Free triiodothyronine(FT3),free thyroxine(FT4),thyroid stimulating hormone(TSH)and the percentage of Th17 cells account-ed for peripheral blood CD4+ T cells(Th17/CD4+)in levothyroxine group before and after treatment were observed and compared with control group,the correlation of Th17/CD4+ and thyroid function. RESULTS:After treatment,Th17/CD4+ level in levothyrox-ine group were significantly lower than before and higher than control group,the differences were statistically significant(P<0.05). TSH in levothyroxine group were significantly lower than before,FT3 and FT4 were significantly higher than before,the differenc-es were statistically significant(P<0.05);compared with control group,the differences were not statistically significant(P>0.05). Th17/CD4+ showed positive correlation with thyroid function in levothyroxine group. CONCLUSIONS:Levothyroxine can signifi-cantly reduce the Th17/CD4+ and TSH,increase FT3 and FT4,and Th17/CD4+ is involved in the occurrence and progression of Hashimoto's thyroiditis.
