Inducible costimulatory molecule(ICOS)is a member of the CD28 family,which can be expressed on the tumor tissues and immune cells in the tumor microenvironment. ICOS enhances its anti-tumor activity through participating in CD4 + T and CD8 + T cell immune response and enhancing the secretion of cyto-kines on the activated T cells and NK cells. While the curative effect of cytotoxic T lymphocyte-associated anti-gen-4(CTLA-4)monoclonal antibody is relevant with CD4 + T cells expressing ICOS,which suggesting ICOS may become a novel anti-tumor therapeutic target in the future.

Objective To compare the clinical characteristics of pregnant women with gestational diabetes mellitus (GDM) and normal gestational glucose metabolism at the 25th weeks of pregnant. Methods Sixty-eighty patients with GDM (GDM group) and 68 patients with normal blood glucose(control group) were enrolled in this study. During 25 weeks of pregnancy, oral glucose tolerance test (OGTT), blood pressure, fasting insulin, glycosylated hemoglobin, uric acid, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol were measured and body mass index (BMI), homeostasis model of assessment for insulin resistence index (HOMA-IR), insulin sensitivity index (ISI) were computed. The results were compared between two groups. Results The age in GDM group was significantly higher than that in control group: (31.38 ± 0.54) years vs. (29.50 ± 0.56) years, P<0.05. The systolic pressure in two groups had no significant difference (P>0.05), but diastolic blood pressure in GDM group was significantly higher than that in control group:(73.2 ± 0.8) mmHg vs. (70.9 ± 0.8) mmHg, 1 mmHg=0.133 kPa, P<0.05. The body weight and BMI in GDM group were significantly higher than that in control group:(65.67 ± 1.76) kg vs. (57.76 ± 1.11) kg, (24.77 ± 0.61) kg/m2 vs. (22.11 ± 0.42) kg/m2, P<0.01. The levels of glycosylated hemoglobin, fasting insulin and HOMA- IR in GDM group were significantly higher than those in control group (5.546 ± 0.746)% vs. (5.085 ± 0.034)% , (17.870 ± 1.015) mU/L vs. (14.400 ± 0.634) mU/L, 4.192 ± 0.271 vs. 2.645 ± 0.128, but the level of ISI in GDM group was significantly lower than that in control group:0.014 ± 0.001 vs. 0.020 ± 0.001, and there were significantly differences (P<0.01). The levels of uric acid, triglyceride, total cholesterol, high density lipoprotein cholesterol and low density lipoprotein cholesterol in two groups had no significant differences (P>0.05). Conclusions Compared to those with normal blood glucose, the patients with GDM have the characteristics of higher age, higher body weight, higher BMI, higher diastolic blood pressure , higher level of insulin, insulin resistance and decreased insulin sensitivity.

Objective To analyze the detection results of TORCH antibodies for further understanding the TORCH infection situation among different groups in Qujing area .Methods The detection results of 3035 cases of TORCH antibodies were retro-spectively analyzed ,and the detection results were grouped into the male group and female group ,juvenile group and adult group , and the positive rate of TORCH antibodies was statistically analyzed .Results (1) In the TORCH-IgG various antibodies detec-tion ,the positive rate of CMV-IgG antibody was highest(84 .78% ) .In the TORCH-IgM various antibodies detection ,the positive rate of RUV-IgM antibody was highest(9 .92% ) .(2)The positive rates of RUV ,CMV and HSVⅠ /Ⅱ-IgG and IgM antibodies in the female group were higher than those in the male group ,and the differences were statistically significant (P<0 .05) ,but the IgM and TOX-IgG had no statistically significant difference between the two groups (P>0 .05) .(3)The positive rates of TOX ,RUV , CMV and HSVⅠ /Ⅱ-IgG antibodies in the adult group were higher than those in the juvenile group ,the differences were statistical-ly significant (P< 0 .05) .The positive rates of TOX ,RUV and HSV Ⅰ /Ⅱ-IgM antibodies in the adult group were higher than those in the juvenile group ,the differences were statistically significant (P<0 .05) ,but the CMV-IgM had no statistically signifi-cant difference between the two groups (P>0 .05) .Conclusion The infection rates of CMV ,RUV ,HSVⅠ /Ⅲ were higher in Qu-jing area .The infection rates are higher in the adult group and female group .Therefore ,TORCH infection should be early found and the infected persons should take some intervention and treatment measures .

There is a huge demand of assistive service from persons with disabilities in China. To set up a security system of assistive technology at nation level will help the disabled to get service. This paper introduced the function of assistive device, discussed the necessity of setting up assistive service security system from the perspective of human right, social civilization, government duty, social security, in-dustry.

Objective:To study the environment suitability of multi-parameter patient monitor. Methods: Choosing six different types of multi-parameter patient monitor from different manufactures, we tested six main parameters of the multi-parameter patient monitor when they had gone through the environmental tests, and the test limits come from field environment. Results:Each of the samples was not up to the standards. Conclusion:At present a clear most of the multi-parameter patient monitor in the market are designed and produced for using indoors, which are not suitable for using in field environment. We need to enhance the protection of the multi-parameter patient monitor against field environment, and improve the environment suitability.

Objective To explore the correlation between serum cytokines and the depression degree in the patients with colorec-tal cancer.Methods 9 6 cases of colorectal cancer were selected and divided into 2 groups according to the patients health question-naire(PHQ-9):the depression group (52 cases)and the non-depression group (44 cases),and 40 healthy cases were recruited as the control.Serum interleukin-2 (IL-2),soluble interleukin-2 receptor (SIL-2R)and tumor necrosis factor-α(TNF-α)were detected by enzyme-linked immunosorbent assay(ELSIA).The detection results were compared among various groups.And the correlation be-tween the expression of various cytokines and the depression degree was analyzed by the Pearson′s correlation coefficient.Results The levels of IL-2,SIL-2R and TNF-αhad statistical differences among 3 groups (P<0.05);no statistical difference in the TNF-αexpression was noted between the depression and the non-depression groups (P>0.05),but which in these two groups was higher than that in healthy group (P<0.05);the IL-2 level in the depression group was significantly lower than that in the non-depression group(P<0.05);the SIL-2 R level in the depression group was obviously higher than that in the non-depression group (P<0.05), moreover,which in these two groups was higher than that in the healthy group (P<0.05).By correlation analysis,the depression degree in the patients with colorectal cancer was negatively correlated with the IL-2 level (r=-0.259,P<0.05)and positively correlated with the SIL-2R level(r=0.412,P<0.05).Conclusion The levels of IL-2 and SIL-2R have certain correlation with the depression degree in the patients with colorectal cancer,it is speculated that the above cytokines may play a mediating role in the pathogenesis process of depression in the colorectal cancer patients.
