ObjectiveTo observe the changes of serum homocysteine acid ( Hcy),interleukin-6 (IL-6) and high sensitive C-reactive protein (hs-CRP)and elucidate the clinical significance in patients with acute stroke. MethodsA total of 126 acute stroke patients were enrolled in the investigation. Based on the MESS,patients were divided into different groups according the severity and prognosis, and 108 physically healthy subjects were selected as controls. The concentration of serum Hcy, IL-6, and hs-CRP were determined in all cases after being attacked at day 3,day 14 and day 28 respectively. Results①The levels of Hcy, IL-6, hs-CRP in patients with acute stroke were significantly higher than controls ( (58.24 ±9.86) μmol/L vs. ( 17.12 ±4.23) μ mol/L, (59.64 ±13.82) ng/L vs. (18.46 ±4.62) ng/L,(19.78 ±6.12) mg/L vs. (2.28 ±0.82) mg/L,all P＜0. 01 ). ②The levels of Hcy,IL-6, hs-CRP in patients with mild, moderate and severe acute stroke were significantly higher than controls (P ＜ 0.01 ) at 3 day after the onset; and the Hcy, IL-6, hs-CRP were also significantly lower in mild cases with acute stroke compared with moderate and severe cases (P ＜ 0. 01 ). At day 14 ,the moderate and severe patients had significantly higher levels of Hcy, IL-6, hs-CRP than mild cases and controls (P ＜ 0.01 ). At day 28 the severe patients had significantly higher levels of Hcy, IL-6, hs-CRP than mild and moderate cases and controls (P ＜ 0.01 ) ③At day 28, the levels of Hcy, IL-6, hs-CRP in basically recovered and remarkably improved cases were significantly lower than unrecovered cases [ ( 16.12 ± 4.74) μmol/L, ( 1 8.42 ± 5.02) μ mol/L vs. ( 48.69 ± 7.89)μmol/L; ( 19.52 ± 5.67 ) ng/L, ( 20. 74 ± 6. 13 ) ng/L vs. ( 51.26 ± 11.66 ) ng/L, ( 3.21 ± 1.36) mg/L,(3.24 ± 2.51 ) mg/L vs. ( 8.86 ± 1.32 ) mg/L respectively, all P ＜ 0. 01 ]. ConclusionsThe levels of serum Hcy, IL-6, hs-CRP are significant biomarkers to evaluate the severity and prognosis of acute stroke.

Objective To explore the patients satisfaction with participation in medical and nursing decision making and the influencing factors among cancer patients, and to provide a basis for developing better medical care services. Methods Totally 159 cancer patients were recruited from Beijing Cancer Hospital, and then were investigated with the general information questionnaire, the patients′ expectation for participation in clinical decision making scale, the patients′ competence for participation in clinical decision making scale, and the patients′satisfaction with participation in medical and nursing decision making questionnaires. Results The total score of patients′satisfaction with participation in medical and nursing decision making were (45.92±3.91) and (34.25±3.31) respectively. Compared with female patients, male patients had higher satisfaction with medical decision making (46.45±3.24&44.87±4.84) and nursing decision making (34.68 ± 2.93&33.42 ± 3.84) (t=2.416, P=0.017;t=2.275, P=0.024);and compared with melanoma patients, lung cancer patients had higher satisfaction with medical decision making (46.51 ± 2.69&43.33 ± 7.07, P=0.002);compared withⅢstage patients, Ⅳstage patients had higher satisfaction with nursing decision making(34.97±2.24&32.40±4.56, P<0.01). Meanwhile, the satisfaction with participation in decision making was significantly positively associated with patients′ expectation and competence for participation in clinical decision making. Conclusions Patients′satisfaction for decision making may vary from different gender, tumor types, disease stages, and patients′expectation and competence. Health care providers still further strength patients′ knowledge and initiative of decision making, and then improve patients′satisfaction with participation in decision making.

This study is to elucidate the immunoregulation mechanisms of artesunate (AST) on allergic contact dermatitis (ACD). Pharmacodynamics analyses, HE staining, semi-quantitative RT-PCR and Western blotting were used to explore the effects of AST on the related cytokines, transcription factor and signaling molecule of ACD respectively. The results indicated that topical administration of AST not only reduced the increase of ear swelling, spleen index and inflammatory cells infiltration in ACD mice, but also inhibited remarkably the expression of IFN-gamma, T-bet and NF-kappaB p65. It's suggested that AST could exhibit suppressive effects on inflammatory response and immune function of ACD, which indicates the possibility of developing AST as a novel immunoregulatory agent in the treatment of ACD and other immune-related diseases.

Objective To investigate the possibility and mechanism of ~ 125 I in treatment of glioma. Methods SHG-44 glioma cells were cultivated in vitro, the inhibitory effect of ~ 125 I on SHG-44 cell proliferation was determined by MTT method. The stereotactic method was used to establish the rat intracranial glioma model. The MRI was performed at 1st week after implantation and ~ 125 I was implanted in the glioma area, the MRI was performed to measure the diameter of tumor 2 weeks after implantation. The rats were killed after 2 weeks ,PCNA gene experession was determined with immunohistological method both in control and experiment group.Results one week after implantation the glioma grew,the results of MTT method showed the growth of the SHG-44 was inhibited, ~ 125 I inhibited the expression of PCNA gene and enlonged the rat survival period. Conclusion ~ 125 I can inhibit the growth of glioma ,the mechanism may be concerned with its inhibitory effect on PCNA gene expression.

Objective:To detect the expression of IDO, iNOS, gp91 NADPH ox releated with IFN-? function following Chlamydia trachomatis lung infection in mice and to investigate the immunological defense mechanism of IFN-?. Methods:A murine model of pneumonia induced by intranasal inoculation of Chlamydia trachomatis,mouse pneumonitis (MoPn) biovar,was used for this study. Chlamydial growth in the lung was assessed by inoculating HeLa 229 cell monolayer with lung homogenates followed by HRP conjugate anti-Chlamydial LPS mAb.The mRNA expressions of IDO, iNOS, gp91 NADPH ox and IFN-? in the lung were determined by RT-PCR on day 7 and 14 postinfection.Results:Chlamydial growth in the lung was observed on day 2 postinfection, peaking at day 7 with subsequent decline in quantity. At day 21 following inoculation, the IFU declined to the baseline. Contrast with the uninfected group, Th1-like cytokine IFN-? underwent a significant increase at day 7 and a decrease on day 14 postinfection. mRNA expression for IDO, iNOS, gp91 NADPH ox was significantly increased in the lungs on day 7 and 14 postinfection, IDO and gp91 mRNA expression was significantly highler at day 7(P
