Objective:To study the correlation of Th subsets in peripheral blood(PB)and IL-1 7 in gingival crevicular fluid(GCF)in the patients with periodontitis.Methods:1 0 healthy controls,1 1 cases with chronic periodontitis(CP)and 8 cases with aggressive pe-riodontitis(AgP)were included.Th1 ,Th2 and Th1 7 in PB were measured by flowcytometry,IL-1 7 in GCF was examined by ELISA. Periodental indexes(PLI,PD,AL and BI)were measured.Results:In the CP group and the AgP group,Th1 and Th1 7 were signifi-cantly higher,Th2 was lower than those in the control group(P <0.01 )(between CP and AgP groups,P >0.05),and IL-1 7 in GCF were significantly higher(P <0.01 )(between CP and AgP groups,P >0.05).In group CP IL-1 7 leve in GCF was positively correla-ted with PD and AL(P =0.000),in group AgP with PD(P =0.007).Conclusion:Deficiency of immunologic function and increase of IL-1 7 in the GCF is related with the onset and development of periodontitis.

This paper discusses non-contact detection technologies in medical service. With the progress of science and technology, non-contact detection technologies for life parameters, based on microwave technology, infrared technology, laser technology and so on, will be more and more important in the development of digital medical equipment.

To evaluate the curative effect of antisense telomerase ODN on malignant glioma cells. The activity of telomerase in 16 fresh malignant gliomas was detected positive by PCR ELISA method. After covered with lipofectin, the 5?mol/L telomerase ODN was incubated with cultured gliomas cells. PCNA, TUNEL positive rate and the phase of cell cycle were detected by FcM per 24h. The results showed: Anti sense ODN inhibited telomerase activity after being applied for 48 hours, and inhibition was complete at 72 hours, The ODN inhibited proliferation of malignant gliomas and promoted their apoptosis markedly at 72 hours. After 96 hours, most transfected glioma cells were stopped to grow at G 2/M phase, and the number of apoptosis cells increased as time went on. The results suggested that anti sense telomerase ODN could inhibit the telomerase activity, and in turn promote aptoptosis of glioma cells and inhibit the growth of the tumor.

To establish the proliferation and apoptosis index(P/AI), and to explore its relationship to the malignant degree of gliomas. Specimens of normal brain tissues obtained from 8 patients undergoing decompression operation for head injury, and 69 paraffin-embedded specimens and 26 fresh specimens of the glioma were studied. Immunohistochemical staining of proliferation cell nuclear antigen (PCNA) and terminal deoxynucleotidyl transferase mediated dUTP DIG nick end labeling(TUNEL) were used to determine the proliferation and apoptosis rates of the glioma. Grading was defined by the ratio between PCNA positive rate and TUNEL positive rate (P/AI). An increase in P/AI denoted an increase in malignancy. It was found that P/AI of normal brain tissue was 0.2-1.5. In 85.1% of grades Ⅰ and Ⅱ gliomas, P/AI was lower than 2.5 and while in 91.7% of grades Ⅲ and Ⅳ gliomas P/AI was 2.5. There were significant differences between normal group, grades Ⅰ and Ⅱ and grades Ⅲ and Ⅳ over gliomas (P

Objective To study the clinical effect of homemade rapamycin-eluting stent on acute myocardial infarction(AMI).Methods A total of 116 AMI patients who received emergency PCI were divided into two groups,the Cypher group(n=52)and the Partner group(n=64).There was no obvious difference in ages,female ratio,smoking,hypertension,hyperlipidema and diabetes between the two groups.The MACE and the restenosis were the targets we wanted to observe.Results The emergency PCI were all successful.Fifty-five Cypher stents and sixty-four Partner stents were planted.The MACE was 0 during in-hospital and the follow-up.Eleven patients in Cypher group(21.15%)and eighteen patients in Partner group(28.13%)underwent coronary angiography re-examination at the 6 months' post-stenting,the restenosis both being 0.Conclusion The homemade rapamycin-eluting stent is safe and effective in AMI.

It is the measurement of high-loss dielectric to measure the permittivity and conductivity of biologic tissue.But now it is difficult to measure them accurately.Good result is got by measuring complex permittivity of phantom model at2450MHz using perturbation method,which is meaningful for the research on biologic tissue simulation by phantom model.

It is a kind of precise method tomeasure the complex permittivities of the phantom model by vector network analyzer.But it is difficult tomeasure them accurately because the phantom model is jelly-like gel and is hard tobe shaped.Network decompositon method can be used toresolve it and it has great meaning tostudy the phantom model simulating the biologic tissue.

Objective To investigate the clinical effects of fenofibrate and polyene phosphatidylcholine in treatment of non-alcoholic fatty liver disease.Methods 86 patients with non-alcoholic fatty liver disease were randomly divided into two groups.45 cases in therapy group received 0.2g of fenofibrate once a day,and the others in control group received 456mg of polyene phosphatidylcholine for three times per day.All of the patients were treated for 12 weeks.Liver function,blood fat,clinical effect and liver B ultrasonic were analyzed before treatment and after 12 weeks.Results The improvement of liver function,blood fat,and liver ultrasonic imaging in therapy group was better than that in the control group.The cure rate was 82.2％ in therapy group and 63.4％ in control group.There was a statistical significance between the two groups ( x2 =3.874,P ＜ 0.05).Conclusion Fenofibrate had significant therapeutic effect in treatment of non-alcoholic fatty liver disease with lower costs and lower side effects.

Objective To investigate the relationship between hepatitis B virus reactivation and the level of blood T-lymphocyte subsets.Methods T lymphocyte subsets ( CD3,CD4,CDs ),CD4/CDs level of 40 patients with chronic carriers of hepatitis B virus and 35 patients with hepatitis B virus re-activation were detected by Flow cytometry(Epics XL).Results The hepatitis B virus reactivation in patients with CD3,CD4 and CD4/CDs levels were significantly lower than the chronic hepatitis B virus carriers,The difference between the two groups patients was significant[(71.31 ±5.20)％ vs (68.57 ±6.10)％,(37.82 ±4.90)％ vs (32.12 ±5.93)％,(1.37 ±0.28) vs (1.18 ±0.43 ),all P ＜ 0.05].Conclusion The levels of CD3,CD4 and CD4/CD8 ratio were significantly declined,it may be the one important reason of hepatitis B virus reactivation.

Objective To detect circulating CD4 + CD25 + regulatory T cells (Treg) and Toll-like receptor(TLR)2 and TLR4 expression on the peripheral blood mononuclear cells (PBMCs) of patients with HBV-related liver cirrhosis (LC), and to explore the correlation between them. Methods PBMCs isolated from 30 LC patients, 21 chronic hepatitis B (CHB) patients and 16 normal controls(NC) were stained with fluorescent labeling anti-TLR2-PE, anti-TLR4-APC, anti-CD14-FITC monoclonal antibodies and anti-CD4-PerCP, anti-CD25-FITC, anti-CD127-PE. Samples were detected by flow cytometry. Statistic analysis be-tween groups was performed by Kruskal-Wallis H test. Spearman rank correlation was used to analyze the correlation of Treg and TLR2, TLR4. Results The expression of TLR2 and TLR4 were significantly up-reg-ulated in patients with LC than those in the controls (TLR2 : 200.3 ± 96.8 vs 94.1 ± 17.6, P < 0.05 ; TLR4:32.1 ±7.2 vs 17.8 ±3.9, P<0.05). The expression of TLR4 was significantly increased in pa-tients with LC than those in patients with CHB (TLR4 : 32. 1 ± 7.2 vs 25.2 ± 8.3, P < 0.05), but there were no differences of TLR2 expression between LC and CHB(200.3 ± 96.8 vs 214.0 ± 72.6, P > 0.05). Treg/CD4+ T cells were 5.07% ±1.43%, 5.88% ±1.66%, 4.21% ±1.24% in patients with LC, CHB and NC, respectively. Treg/CD4+ T cells were significantly increased in patients with CHB than those in pa-tients with NC(P<0. 05) and LC(P <0.05), but there were no differences between LC and NC(P > 0.05). TLR4 expression and Treg were positive correlation (r = 0. 469, P = 0. 032) and TLB2 expression were negative correlation in patients with LC (r = -0.428, P = 0.021). Conclusion The expression of TLR2 and TLR4 were up-regulated on PBMCs in patients with LC. It seems to be expression of TLR2 and TLR4 in-volved in the pathogenesis of LC.
