Objective To investigate the change of interle ukin -4(IL -4)in experimental murine systemic candidiasis.Methods In the dexamethasone -induced immuno -suppressed murine systemic can-didiasis models and control healthy mice,two -site ELISA and RT -PCR were applied to determine the levels of IL -4protein or mRNA expression in th e spleens respectively.Colony form ing units(CFUs )of infected kidneys were determined with the plating dilution method,and the mean survival t ime (MST)of mice was also recorded.Results The IL -4concentration in the spleen of healthy mice was 80.1?19.1pg /g.I n contrast,in those infected with lethal dose of yeasts t he concentrations of IL -4were 124.8?24.1pg /g and 262.8?21.8pg /g on 3days or 7days after infection respectively.Meanwhile,the fungal lo ads in kidneys were(21.25?6.31)?102CFUs and(57.52?10.41)?102 CFUs on 3days or 7days after infectio n(P

Objective To investigate the expression levels of of interleukin-17(IL-17),interferon-gamma(IFN-?),and macrophage inflammatory protein-3alpha(MIP-3?)mRNA in skin lesions of pa-tients with psoriasis vulgaris.Methods The skin biopsies were collected from skin lesions in31cases of psoriasis vulgaris and16normal controls.The expressions of IL-17,IFN-?,and MIP-3?mRNA were semi-quantitatively analyzed with reverse transcriptase-polymerase chain reaction(RT-PCR)in psoriatic lesions and normal skin tissues.Results Expressions of IL-17,IFN-?,and MIP-3?were presented in all speci-mens of both psoriatic lesions and normal controls.The expression levels were1.142?0.059for IL-17mRNA,1.114?0.056for IFN-?mRNA,1.140?0.052for MIP-3?mRNA,in skin lesions,respectively,which were greatly higher than those in normal controls(0.879?0.034,0.905?0.026and0.868?0.031,respectively)(all P

Objective To investigate the role of CD80/CD86 and CTLA-4 in the pathogenesis of systemic lupus erythematosus(SLE) and its clinical significance. Methods Applying RT-PCR technique to semiquantitatively analyze CD80/CD86 and CTLA-4 mRNA expression on peripheral blood mononuclear cells (PBMC) from 32 active SLE patients. Results Compared with normal controls, the percentage of positive CD86 expression in active SLE, accounted for 90.63% (29/32), was significantly increased (P 0.05, both). Conclusion The abnormal expression of CD86 and CTLA-4 might play an important role in the pathogenesis of SLE.

To study the expression of p63 and cyclooxygenase-2 (cox-2) in skin tumors and evaluate the correlation between p63 and cox-2, the expressions of cox-2 and p63 were measured by streptavidin-peroxidase complex immunohistochemical technique in 17 cases of skin squamous cell carcinoma (SCC), 19 cases of Bowen's disease(Bowen), 11 cases of actinic keratosis(AK), 12 cases of seborreic keratosis(SK) and 13 specimens of normal skin. Our results showed that the expression of p63 in skin squamous cell carcinoma, Bowen's disease and actinic keratosis were significantly higher than that in seborreic keratosis, while the expression of p63 in seborreic keratosis was significantly higher than that in normal skin. The expression of cox-2 in skin squamous cell carcinoma, Bowen's disease and actinic keratosis were significantly higher than that in seborreic keratosis, while no statistical difference was noted in the expression of cox-2 between seborreic keratosis and normal skin. Cox-2 expression was positively correlated with the high p63 expression in malignant skin tumors. The increased expression of cox-2 and p63 may play an important role in the development of skin tumors and work synergetically in malignant skin tumors.

In order to investigate the role of Th17 cytokines in the pathogenesis of psoriasis, reverse transcriptase-polymerase chain reaction (RT-PCR) was used to detect the expression of IL-17, IL-23 (p19/p40), and IL-6 in skin lesions and non-lesions of the patients with psoriasis and skin tissues of normal subjects. The results showed that the mRNA expression levels of IL-17, IL-23p19, IL-23p40 and IL-6 in psoriasis lesion were significantly higher than those of non-lesions (1.231 +/- 0.843 vs 1.003 +/- 0.044, 1.166 +/- 0.142 vs 0.765 +/- 0.133, 1.125 +/- 0.104 vs 0.730 +/- 0.103, 1.186 +/- 0.222 vs 0.976 +/- 0.122, respectively, all P < 0.05). Meanwhile, The expression levels of IL-17 mRNA, IL-23p19 mRNA, IL-23p40 mRNA and IL-6 mRNA were higher in non-lesions than those in normal skin tissues (1.003 +/- 0.044 vs 0.620 +/- 0.104, 0.765 +/- 0.133 vs 0.584 +/- 0.078, 0.730 +/- 0.103 vs 0.000 +/- 0.000, 0.976 +/- 0.122 vs 0.656 +/- 0.121, respectively, all P < 0.05). The overexpression of Th17 cytokines in the skin lesions of patients with psoriasis may indicate that Th17 cytokines play a very important role in the immunopathogenesis of psoriasis.

To investigate the role of toll-like receptor 9 (TLR9) in the pathogenesis of lichen planus, the expressions of TLR9 and its mRNA in the lesional skin of lichen planus were detected by immunohistochemical technique (SP) and RT-PCR. As control, normal skin of healthy volunteers was also tested. The immunohistochemical study showed that the expression of TLR9 in the lesional skin of lichen planus was significantly higher than that in the normal controls. The results of RT-PCR showed that both skin lesions and normal controls had TLR9 expression. In skin lesions, the expression level of TLR9 mRNA was 1.6075+/-0.0930, which was significantly higher than that in normal controls (P<0.001). These findings indicated that up-regulated expression of TLR9 and its mRNA might be involved in the pathogenesis of lichen planus.

Objective To investigate the malnutrition status among the elderly in age care institutions in Shanghai suburb and analyze its potential influential factors.Methods The MiniNutritional Assessment (MNA) was adopted to evaluate the nutritional status of the 190 elderly people in age care institutions.The dietary supply by the institution canteen and the quantity of residual food left by the malnourished elderly people were weighted.Results In the age care institutions,the malnutrition rate reached 23.7％,47.9％ of the elderly people were at the risk of malnutrition,and only 28.4％ of the elderly people were well nourished.Logistic regression analysis showed that the major influential factors for malnutrition in the elderly people were food intake ability,mobile capability,chewing and swallowing ability,ageing and mental Illness.The malnourished elderly people had the most residual meat and vegetables,and insufficiency of nutrient intake was the main cause for the malnutrition in the elderly people.Conclusions The elderly people in age care institutions in Shanghai suburb have the higher risk of malnutrition.The malnutrition occurs under influence of many factors,of which some are unavoidable,however,some factors like dietary factors can be changed to improve the nutritional status of the elderly people in age care institutions.
