Objective: To study diagnostic and predictive value of levels of high sensitive C reactive protein (hsCRP) and cystatin C (CysC) for acute coronary syndrome (ACS) in aged patients.Methods: A total of 60 ACS patients (ACS group) treated in our hospital and 60 healthy subjects (healthy control group) undergoing physical examination during Dec 2013 to Sep 2015 were randomly selected.Serum levels of hsCRP and CysC, and abnormal rates of hsCRP and CysC were measured and compared between two groups.Results: Compared with healthy control group, there were significant rise in serum levels of hsCRP[(3.02±1.13) mg/L vs.(7.95±2.38) mg/L]and CysC[(0.75±0.11) μg/ml vs.(1.35±0.43) μg/ml], and abnormal rates of hsCRP (0 vs.13.33%) and CysC (0 vs.11.67%) in ACS group, P<0.01 all.Conclusion: Serum hsCRP and CysC level measurements can effectively predict and assess occurrence, development and prognosis of disease in ACS patients, and provide clinical valid evidence for its diagnosis, prevention and treatment.

Objective:To analyze the relationship among smoking, levels of homocysteine (Hcy), cystatin C (CysC), C reactive protein (CRP) and coronary heart disease (CHD) onset in young people.Methods:A total of 152 patients, who received selective coronary angiography because of chest pain in our hospital, were enrolled, and all subjects were <45 years old.According to examination results, they were divided into CHD group (n=100) and non-CHD group (n=52).Clinical data were analyzed in both groups, and Logistic multi-factor regression analysis was used to analyze independent risk factors for CHD in young people.Results:Compared with non-CHD group, there were significant rise in percentages of men (30.8% vs.65.0%), smoking (46.1% vs.68.0%) and hypertension (34.6% vs.51.0%), levels of CysC[(0.85±0.16) mg/L vs.(1.34±0.28) mg/L], CRP [(1.26±0.85) mg/L vs.(6.93±0.85) mg/L] and Hcy[(7.16±1.16) mol/L vs.(20.85±2.16) mol/L],P<0.05 or <0.01;multi-factor Logistic regression analysis indicated that male, hypertension, smoking, Hcy, CysC and CRP were risk factors for CHD in young people (OR=1.34~3.42, P<0.05 or <0.01).Conclusion:Male, smoking, total cholesterol, homocysteine, Cys C and C reactive protein are risk factors for CHD in young people.Therefore, these risk factors should be eliminated, or its risk should be reduced.

Objective To observe the effects of Triptolide on the expression of toll-like receptor 4 (TLR4) in renal ischemia/reperfusion (I/R) injury in rats. Methods A renal I/R model was established. Rats were randomly separated into the following experimental groups. Group 1, shamoperated control (n = 15) : rats were subjected to surgical manipulation, without the induction of renal ischemia. Group 2, I/R (n = 18): rats were subjected to left renal ischemia for 45 min followed by reperfusion. Group 3, TRI + I/R (n = 18): Before the I/R procedure (as in group 2), rats were intraperitoneally injected with TRI (0.4 mg/kg), once every day, three times. Rats were killed at the 1st, 3rd, and 5th day after I/R injury. The parameters of renal function were determined by autobiochemical analyzer. The expression of TLR4 was detected by RT-PCR and Western blotting. Results As comparedwith the sham-operated control group, serum BUN and Cr levels were significantly increased in the rats undergoing I/R procedure at the 1st, 3rd, and 5th day (P＜0. 01). After the treatment with TRI, the levels of BUN and Cr and the expression of TLR4 in the renal tissues were significantly decreased (P＜0. 05). Conclusion TRI could relieve renal I/R injury in rats by inhibiting the TLR4 expression.

ObjectiveTo investigate the protective effect of ozone oxidative preconditioning (OzoneOP) on apoptosis induced by acute renal ischemia/reperfusion (I/R) injury in rats.Methods The right kidneys of rats in control group were excised.A rat I/R model was established in I/R group.In OzoneOP group,the renal OzoneOP was induced by rectal insufflation of 5.0～5.5 ml oxygen plus ozone (ozone 50 mg/L,1 mg· kg- 1 · d- 1,once every day).The parameters (blood urea nitrogen and creatine )of renal function were determined by auto-biochemical analyzer. The concentrations of malondialdehyde (MDA) and superoxide dismutase (SOD) were measured by using chromometry.Cytochrome c (CytC) was examined by using immunohistochemistry and Western blotting.The mRNA expression levels of TNF-α,IL-1β and IL-6 in the renal tissue were detected by using RT-PCR.ResultsCompared with the control group,the blood urea nitrogen,creatine,MDA and the release of CytC were increased significantly in I/R group.After OzoneOP,the levels of blood urea nitrogen,creatine,MDA,CytC and the mRNA expression levels of TNF-α,IL-1-β and IL-6were significantly decreased and SOD levels were significantly increased.ConclusionOzoneOP could relieve renal I/R injury of rats by improving antioxidation capability,cutting down cytokines contents and inhibiting the release of CytC from mitochondria.

Objective To evaluate the predictive value of urinary neutrophil gelatinase-associat-ed lipocalin (NGAL) and interleukin-18 (IL-18) for delayed graft function (DGF) in kidney transplan-tation. Methods Serial urine samples collected at 0, 12 and 24 h after operation from 86 kidney transplantation patients were analyzed by enzyme-linked immunosorbent assay for NGAL, IL-18 and RBP. Results Fifteen patients developed DGF. At 12 h after transplantation, the level of urine NGAL elevated significantly (1712.75±474.6 vs. 863.1±199.8 without DGF, P<0. 001). The in-creases of urine IL-18 (29. 2±4.1 vs. 28.7±4.2 without DGF, P>0. 05) was not significant. At 24 h, both urine NGAL(2905.0±1108.1 vs. 911.8±221.0 without DGF,P<0. 001) and IL-18(211.3± 34.0 vs. 86.9±22.8 without DGF, P<0. 001) increased significantly, whereas the changes of urine RBP and serum creatinine (SCr) were not significant. ROC analysis showed that the area under the curve of NGAL and IL-18 were 0. 90 and 0.76 respectively, the cut-off values were 996.5 ng/mg and 148.5 ng/mg, the diagnostic sensitivities in DGF were 90.2% and 76.3%, specificities were 82.6% and 66.4% respectively. Conclusions Both urine NGAL and IL-18 could potentially be early predic-tive marker of DGF. The level of NGAL elevated earlier than IL-18, which may be more effective in predicting DGF.
