BACKGROUND: The efficacy of Cyclosporin A(CyA) in the treatment of psoriasis is well recongized, the dosage less than 5mg/kg per day(mg/kg/d) is recommended. OBJECTIVE: The purpose of this study is to evaluate the indication, dose, course and side-effects of CyA therapy for psoriasis, especially in China. METHODS: Forty patients with psoriasis were treated with doses of CyA 5mg/kg/d, compared with 20 patients treated with Tigason lmg/kg/d by Global PAST. RESULTS: 1. Of 40 patients 33 patients (82.5%)were cured clinically in 4-5weeks and all the patients(100%) had responses to the therapy. 2. The efficacy and the Global PASI reduction of CyA therapy were significantly better than that of Tigason therapy. 3. During the CyA therapy, no severe side-effects and obvious laboratory changes were found. CONCLUSION: CyA(5mg/kg/d) was satisfactory for psoriasis, especially for psoriasis pustulosa, arthropathica and erythroderma. CyA was found to be superior to Tigason. The therapy course and side-effects seemed to be related to the dosage.

Objective To investigate the relationship between breast cancer and G919A polymorphisms of CBS (cystathionine β synthase) in patients with breast cancer in Han nationality in Xinjiang. Method Three hundred breast cancer patients and 300 normal controls of Han nationality were genotyped by ARMS method, and then the relative biochemical indicators were detected by the automatic biochemical analyzer. Results The Hcy level of breast cancer patients were higher than that of control group (P < 0.05). Genotypes GG, GA, AA of CBS G919A and allele G,A, in breast cancer patients were 63.7%, 24%, 12.3% and 75.7%, 24.3% respectively, which had no statistically significance when compared with those of the controls (P > 0.05). Conclusion The high level of Hcy may be a risk factor for breast cancer in Han nationality in Xinjiang and there was no relationship between CBS G919A polymorphism and breast cancer.

Objective:To study the role of IL-2,IL-4,IL-6,IL-10,IL-13 and IFN? in pathogenesis of human tumor.Methods:The gene expression of 6 cytokines in human tumor cell lines and specimens were detected by RT-PCR or RNA dot hybridization.Results: There were predominant expression of Th2 type cytokines in 183 different human tumor cell lines and specimens.The positive rate of IL-4,IL-6,IL-10,IL-13 .IFN? and IL-2 in 183 tumor cell lines and specimens were 65%,70.5%,83.6%,61.7%, 12.6% and 22.9%,respectively.Conclusion: Predominant expression of Th2 type cytokines play an important role in the pathogenesis and development of tumor, may be related to the evasion of tumor cells from immune surveillance.

Objective:To investigate the influence of concanavalin A(Con A) pretreatment on the development of the fulminant murine hepatitis induced by an adequate dose of Con A.Methods:An adequate dose of Con A(15 ?g/g.body.wt) was injected intravenously into C57BL/6 mice to provoke severe liver damage,an extensively-used murine hepatitis model.A low dose of Con A(3 ?g/g.body.wt) was administrated intravenously 12 h before injection with an adequate dose of Con A.Liver injury was evaluated by serum transaminase assay and H&E staining.Hepatic lymphocytes were analyzed by flow cytometry and the absolute amount of lymphocytes per liver was calculated.Results:Pretreatment with a low dose of Con A significantly inhibited Con A-induced liver injury.Both the percentage and the absolute number of liver CD3~+T cells in Con A-pretreated mice were lower than those of PBS-pretreated mice.The activation of liver CD3~+T cells in Con A-pretreated mice was also prominently inhibited.Conclusion:Con A pretreatment exerted the negative effect on the development of Con A-induced hepatitis,which may be result from the decreased recruitment of T cells into the liver.The underlying mechanisms are under investigation.
