Objective To investigate the relationship between IL-18 and apoptosis in patients with SLE by using testing the changes of IL-18 and soluble Fas/soluble Fas ligand in sera from the patients.Methods 58 patients with SLE were divided into three groups according to their SLEDAI score;sera from 58 patients,and 30 normal controls were tested for IL-18 and sFas/sFasL using ELISA assay.Results The level of IL-18 and sFas in sera from SLE patients was significantly higher than that of normal controls(P0 05).Besides,the increased level of IL-18 was correlated well with the increased level of sFas (?=0 496,P0 5).Conclusion The increased level of IL-18 may result in the elevation of serum sFas/sFasL in patients with SLE.They may play important roles in the pathogenesis of SLE.

Objective To investigate the expression and prognostic significance of Interleukin-36α (IL-36α) in colorectal cancer.Methods The expression of IL-36α was tested by immunohistochemical staining in 329 cases of colorectal cancer.According to the intensity and the proportion of positive tumor cells,all the patients were divided into IL-36α low and high expression groups.The clinicopathological factors and prognosis of patients between IL-36α low high expression groups were compared.Results Significant differences were observed in the number of patients in tumor differentiation and pM classification between patients in the IL-36α low and high expression groups (P ＜ 0.05).The 5-year overall and tumorfree survival rates of patients were 79.3％ and 77.2％ in IL-36α low expression group,and 66.3％ and 65.3％ in IL-36α high expression group (P ＜0.05).COX proportional hazard regression model revealed that high expression of IL-36α was associated with short overall survival time and tumor-free survival time of colorectal cancer patients (P ＜ 0.05).Multivariate analysis identified IL-36α expression in colorectal cancer as an independent prognosticator (P ＜ 0.05).Conclusions High expression of IL-36α was correlated with tumor differentiation and pM classification of colorectal cancers,and it is an independent predictor of poor survival for patients with colorectal cancer.

OBJECTIVE:To investigate the compatible stability of cefpirome sulfate with ornidazole. METHODS:At room temperature [(20±1)℃],the appearances(color,clarity,sedimentation and gas)and pH changes of the mixtures by Cefpirome sulfate for injection with Ornidazole for injection in 0.9% Sodium chloride injection and 5% Glucose injection after 0,1,2,4,6 h were observed. RP-HPLC was adopted to determine its content changes. RESULTS:No significant change was noted for the mix-ture in appearance within 6 h,pH value ranged in 3.359-3.588;compared with the beginning(0 h),the contents of cefpirome sul-fate and ornidazole ranged in 100.2%-100.3%,99.9%-100.4% in 0.9% Sodium chloride injection at each time point,as well as 99.7%-99.9%,99.4%-99.6%in 5%Glucose injection. CONCLUSIONS:At room temperature,cefpirome sulfate mixed with orni-dazole show stable appearance,pH value and content in 0.9%Sodium chloride injection and 5%Glucose injection within 6 h.

Objective To explore the recuperative effect of immunological function and nutritional status on the patients treated by immune enteral nutrition in early stage after severe multiple injury (SMI). Method The patients with SMI,in department of Trauma Surgery,Tongji Hospital,Tongji Medical College, Huazhong University of Science and Technology,between January 2006 to May 2007 were randomly divided into 2 groups: immune enteral nutrition group (IEN group, 20 cases), enteral nutrition group (EN group, 20 cases). The health persons served as the control group(15 cases) .Since 1st postinjury day, all patients were treated with nutritional support. The T-cell subgroup in periphera blood were detected by FCM and the level of PA, RBP, IL-2 and IL-4 in blood serum were detected by ELASA on the 1st, 3rd,5th, 8th postinjury day. Results After the treatment of IEN and EN,the serum levels of PA, RBP and the proportion of T-cell subgroup were significantly increased on the 8th postinjury day compared with on 1st postinjury day (P ＜ 0.01), but there were no differences between IEN group and EN group. The level of IL-4 were significantly decreased and the level of IL-2 were significantly increased in each group on 8th postinjury day, at same time, the level of IL-2 were significantly increased in IEN group compared with EN group (P ＜ 0.05), and the level of IL-4 were significantly decreased in IEN group compared with EN group (P ＜ 0.05). The duration of SIRS was transient and the infected complication was low on the patients treatment by IEN than EN. Conclusions On the patients with severe multiple injury, IEN was most ascendant than EN to improve the immunosuppression and clinical prognosis.

Objective To explore the expression of intercellular adhesion molecule-1(ICAM-1) in the brain edema induced by lipoposacchride(LPS) in rats under the action of dexamethasone.Methods One hundred and fifty healthy SD rats were randomly divided into three groups of 50 each:normal saline group(NS group),LPS group and dexamethasone group(DXM group).Each group were again divided into 5 groups:4,6,12,24 and 48 h group.Brain edema was induced by LPS.Immunohistochemistry staining methods were used to measure the expression of ICAM-1 in brain tissue of brain edema induced by LPS in rats.And the level of evans blue(EB) was aslo determined.Results At each time point,the content of brain tissue and evans blue(EB) in LPS and DXM group all increased significantly than those in NS group(Pa0.05).In LPS group,brain water content and EB content,expressing quantity of ICAM-1 and brain water content,expressing quantity of ICAM-1 and EB content all had positive relationship(r=0.537,0.467,0.549 Pa

Objective To investigate the expression of protein tyrosine phosphatase(PTP)1B in pancreas of obese rats induced by high fat diet.Methods Twenty male SD rats were randomly divided into control group on regular diet(n=10),and obesity model group on high fat diet(n=10).After twelve weeks,fasting serum insulin,blood glucose,triglyceride,total cholesterol,epididymal fat weight were measured and the histomorphological change in liver were observed;glucose tolerance test and insulin releasing test were performed; The protein expression of PTP-1B in pancreas of rats was determined with Western blotting and immunohistochemistry.The phosphorylation of insulin receptor substrate-1(IRS-1)and insulin receptor(IR)were detected by immuno-precipitation.Results(1)The insulin sensitive index was significantly decreased in the high-fat-diet rats compared with the normal rats(0.36?0.18 vs 0.91?0.28,P

Objective To obtain Chinese hamsterovary (CHO) cell line expressing human decay accelerating activity (hDAF) stably and to observe the protective effect of hDAF on heterologous cells under the circumstance of complement activation. Methods The eukaryotic expression vector DAF pcDNA3.1 was constructed and then transfected into CHO cells by lipofection. Monoclones of cells expressing hDAF stably were screened by the method of limiting dilution. hDAF expression was detected by flow cytometry. The decay accelerating activity of hDAF was determined by assay of C3 deposition and 51Cr release. Results The expression vector DAF pcDNA3.1 was successfully constructed, and monoclones of cells expressing hDAF were obtained. CHO cells expressing hDAF could decrease C3 deposition and attenuate the killing effect of activation of the complement system. Conclusion We have obtained CHO cell clones expressing hDAF stably, which is helpful for the further studies of the relationship of the structure with the functions of hDAF.

Previous studies have demonstrated that plasminogen actiator (PA) activity is significantly high in semen of infertile men, which is also high in semen when azoospermia or oligozoospermia is induced by injection of testosterone enanthate (TE) into healthy adult men or rhesus monkeys. To further clarify the source and possible role of PA in semen, the present study was undertaken to examine: (1) whether the mRNAs for tissue type PA (tPA), urokinase type PA (uPA), and PA inhibitor-1 (PAI-1) are expressed in epididymis, seminal vesicle and prostate gland of rhesus monkeys; and (2) whether PA has some effect on in vitro sperm capacitation as judged by the potential of sperm motility, acrosome reaction (AR) and in vitro fertilization. Our results showed that (1) mRNAs for PA and PAI-1 were expressed in epididymis, seminal vesicle and prostate gland, and (2) uPA, but not tPA, improved sperm mobility, induced AR and enhanced sperm capacity to fertilize mature eggs. Thus, it is concluded that PA activity in semen comes not only from testis and epididymis, but also from seminal vesicle and prostate gland; and that uPA, but not tPA, may play a role in sperm capacitation.
