Objectives The relationship between homocysteine ( Hcy ) and lipid levels in renal transplant patients was analyzed to investigate the effect of hyperlipidemia on renal function and the importance of lipid monitoring in renal function after renal transplantation.Methods 492 patients outpatient follow-up of renal transplants from November 2014 to April 2015 in the Department of Urology and 221 healthy subjects from Shanghai First People′s Hospital were enrolled and their serum Hcy, Total cholesterol( TC) ,triglycerides( TG) , High density lipoprotein cholesterol( HDL-C) , Low density lipoprotein cholesterol( LDL-C ) were tested.All the subjects were divided into normal group and abnormal group according to the serum Hcy levels.At the same time serum cysteine protease inhibitor C(CysC) level was tested to estimate glomerular filtration rate(eGFR),grouping according to the principle of Chronic Kidney Disease( CKD)《Kidney Disease Outcomes Quality Initiative》( KDOQI) staging criteria.The co-relationship between serum TC, HDL-C, TG, LDL-C levels and the possibilities of high cardiovascular risk factors, and the relationship between of serum Hcy and lipid levers, kidney function were analyzed based on the standard of“2007 China Adult dyslipidemia prevention and treatment guidelines”.Statistical methods using U test、chi square analysis, correlation and multiple regression analysis.Results The serum TC(4.48 -5.85),TG (1.05-1.91),HDL-C(1.33-2.01),LDL-C(2.53-3.72) and Hcy(11.99-20.23) levels in the renal transplantation group were higher than the control group′s TC ( 4.02-5.33 ) , TG ( 0.81-1.74 ) , HDL-C (1.11-1.58),LDL-C(2.21-3.32), Hcy(8.9-12.4) levels.(P=0.00,0.00,0.00,0.00,P<0.01) In the renal transplantation group,serum Hcy levels was negatively correlated with eGFR and HDL-C levels (r=-0.565, -0.197, P<0.01), and was positively correlated with TG levels.(r=0.107, P<0.05) In renal transplantation group ,the serum levels of HDL-C was significant lower in Hcy-abnormal group(1.15-1.77)than the normal group(1.35 -1.97) (P=0.001,P<0.01),while the serum levels of LDL-C (2.51-3.93) was higher than the normal group(2.44 -3.69) (P=0.023,P<0.05).In the renal transplantation group,the count ratio of lipid risk factors in the Hcy-abnormal group (0 item 55.4%,1 item 23.5%,2 items 14.2%,3 items 6.5%,4 items 0.4%)was higher than normal group(0 item 69.8%,1 item 17.2%,2 items 9.1%,3 items 3.9%,4 items 0.0%) ( P=0.019,P<0.05).Ranked serum Hcy levels with cardiovascular risk factors, high-risk factors count ratio of eGFR 45-60 ml/min/1.73 m2 group was significant higher than eGFR 60-89 ml/min/1.73 m2 group in each level(P=0.018,P<0.05).Logistic regression analysis was carried out on the risk factors of serum TG, LDL-C, Hcy levels respectively, the results show that serum TG,LDL-C,Hcy levels and differences in renal function have statistical significance (P=0.00,0.00,0.00,P<0.01).Conclusions The serum TG,LDL-C and Hcy levels in the renal transplantation group were consistent increase and associated with kidney injury.The differences in TG, LDL-C, Hcy levels of renal transplant patients may cause differences in renal function after transplantation.Monitoring of serum lipids and Hcy levels is helpful for forecast the possibility of kidney injury.

Objective:This study aimed to identify the morphology of mast cells by using a modified toluidine blue staining scheme,so as to provide a powerful reference for the experimental basis research of mast cells.Methods:Bone marrow-derived mast cells were induced in vitro.After 4 weeks,the cells were collected,fixed,and stained.Mast cells were fixed at different temperature during different time.The optimum condition was determined by comparing the effects of toluidine blue staining.Results:Bone marrow cells were induced to differentiate into mast cells by SCF and IL-3 in vitro.When mast cells were stained with modified toluidine blue staining,the staining effect was better.Mast cells were round or oval and the cell membrane was complete and the cytoplasm was filled with a large number of purple particles.Conclusion:In this study,we successfully applied a modified toluidine blue staining method to mast cells cultured in vitro.The results showed that the condition at 37 ℃ full fixation with staining could reduce the degeneration of mast cells.This method was easy to operate with good stability.It was suitable for the morphological observation of mast cells cultured in vitro.

Objective To explore the relevance between lipoprotein(a) and atherosclerotic renal artery stenosis in adults.Methods Literature search was conducted in PubMed and EMBASE Database,using “atherosclerotic renal artery stenosis” as the search term as well as in Wanfang Database,China National Knowledge Infrastructure,and Cqvip Database,using “renal artery stenosis” and “lipoprotein” as the search terms,aiming to find case-control or cohort studies published before 2010.The qualities of all the literatures enrolled were evaluated using Newcastle-Ottawa scale and the data from which were analyzed by the Review Manager 5.0 software.Results Five eligible case-control studies (661 cases) entered the Meta analysis.The results showed that the lipoprotein(a) level was not significantly higher in the case group than that in the control group [ mean difference =0.0702 g/L,95％ CI ( - 0.0688,0.2092),P =0.32 ].Conclusion According to the existing studies,the relevance between lipoprotein(a) and atherosclerotic renal artery stenosis can not be established.

Objective To observe the effect of ulinastatin on the expression of interleukin 15 (IL-15), connective tissue growth factor (CTGF) and malondialdehyde (MDA) in rat peritoneal mesothelial cells (RPMCs) induced by high glucose. Methods RPMCs were isolated, cultured and passaged by trypsin, then identified. The third generation of cultured RPMCs were used in the experiment. RPMCs were divided into normal control group, high glucose (1.5%, 2.5%, 4.25%) for 6 hours and 12 hours, high glucose (2.5%) for 3, 6, 12, 24 hours or ulinastatin (160, 320, 640U/ml) for 12 hours. IL-15 mRNA was detected by real-time PCR. IL-15 and CTGF protein in supernatants was detected by ELISA. MDA protein was detected by TBAS. Results Compared with the control group, the expression of IL-15, CTGF and MDA was significantly increased in the groups stimulated by high glucose (P＜0.05) in dose- and time-dependent manner. Ulinastatin could significantly decrease the expression of IL-15, CTGF and MDA induced by high glucose in dosedependent manner both in protein and gene levels (P＜0.05). Conclusions High glucose can up-regulate the expression of IL-15, CTGF and MDA in RPMCs. Ulinastatin can reverse these changes.

Objective To explore the cytotoxicity of the cytotoxic T lymphocyte (CTL) induced by SW480 sonicate sensitized dendritic cells (DC) on the colon cancer cell line SW480. Methods PBMC were separated from the HLA-A*0201 donor and DC were cultured with rhGM-CSF, rhIL-4 and rhTNF-α. The same donor's primary CTL were stimulated by DC loaded with SW480 sonicate. The cytotoxicity of CTL on SW480 (HLA-A*0201 positive) and K562 (HLA-A*0201 negative) was determined by the MTT method. Results The cytotoxicity of the CTL on SW480 was stronger than that on K562 (P ＜0.05). Conclusion The DC vaccine can stimulate specific CTL which can trigger cytotoxic activity on the target cells and this cytotoxicity is related to MHC restriction.
