International Journal of Laboratory Medicine 2014;(17):2298-2300
Objective To explore the relationship between serum cystatin C concentration and severity of coronary artery disease and prognosis after peripheval component interconnet(PCI)treatment.Methods 352 patients diagnosed as ACS and received PCI treatment successfully were enrolled in the study as ACS group.In addition to that,60 people who underwent coronary angiography and the test results was good were recruited as control group.The serum lipids,cystatin C concentrations were tested,and the rela-tionship between the number of coronary lesions,Gensini score and cystatin C concentrations were analyzed.The risks of major car-diovascular events in different cystatin C concentration groups were analyzed.Results Cystatin C concentrations of ACS group were significant higher than control group (P <0.05).Cystatin C concentrations were significantly different among patients with different number of diseased branches(P <0.05).The patients with higher number of diseased branches were with higher concen-tration of cystatin C.There was a positive correlation between cystatin C concentration and Gensini score (r=0.84,P <0.05).The risk of major cardiovascular events in high cystatin C concentration group within 1 year after PCI treatment increased significantly compared with control group,the OR values were 16.63(95%CI :3.87-71.49,P <0.05).Conclusion Cystatin C correlated with the severity of coronary artery disease and the occurrence of major cardiovascular events within one year after PCI treatment.
2.Research progress of a new therapeutic target in hepatocellular carcinoma glypican-3
Chinese Pharmacological Bulletin 2016;32(11):1486-1489
Glypican-3 ( GPC3 ) plays very important role in the regulation of cell growth and differentiation in hepatocellular car-cinoma ( HCC ) . GPC3 is closely related to the occurrence and development of HCC. A dramatic elevation of GPC3 expression has been reported in a large proportion of HCC, which suggests that GPC3 is remarkably sensitive and specific to the diagnosis of HCC. GPC3 is a potential therapeutic target of HCC. This paper reviews the structure and function of GPC3, the progress of im-munotherapy based on GPC3 of HCC, and discusses the prospect of therapeutic target of liver cancer in the future.

Aim To investigate the apoptosis of human gastric carcinoma AGS cells induced by cecropinXJ. Methods Human gastric carcinoma AGS cells and human normal epithelial cells GES-1 were co-cultured with different concentrations of cecropinXJ ranging from 0. 01 to 1 000 mg·L-1 for 24 h. MTT assay was used to observe the effects of cecropinXJ on the proliferation of AGS cells and GES-1 cells. The ultrastructural changes of the AGS cells were observed by transmission electron microscopy. Hoechst staining was used to de-tect cell apoptosis. The changes of intracellular reac-tive oxygen species ( ROS) and mitochondrial potential were analysed by flow cytometery. The expression of Bax, Bcl-2, caspase-3 and cytochrome C in mRNA level was investigated by qRT-PCR. Western blot was used to determine the protein expression of Bax, Bcl-2, caspase-3 and cytochrome C. Results CecropinXJ significantly suppressed the proliferation of AGS cells in vitro (P<0. 05) in a dose-dependent manner, IC50 =61. 19 mg·L-1 , but had no inhibitive effects on the proliferation of GES-1 cells. After treatment for 24 h, cecropinXJ induced AGS cells nuclear condensation, and increased ROS production, disrupted mitochondri-al integrity. The results of qRT-PCR and Western blot demonstrated cecropinXJ could up-regulate the expres-sion of Bax and down-regulate the expression of Bcl-2 , promote the release of cytochrome C and activate caspase-3. Meanwhile, cecropinXJ promoted caspase-3 activity in a dose-dependent manner, and cell death ratio of AGS cells induced by cecropinXJ was signifi-cantly reduced by caspase-3 and caspase-9 specific in-hibitors treatment. Conclusion CecropinXJ can in-duce apoptosis of AGS cells by downregulating Bcl-2 , upregulating Bax and activating caspase-3 , which may be one of its anti-tumor mechanisms.

Objective:Antimicrobial peptides ( AMPs ) are peptides generated in the biological defense system against exogenous pathogens ,which is all important constituent of the non-specific immune system.The immune system can react and sometimes play an important role in tumor control both in animal models and in humans.In this study,CecropinXJ were used in the BALB/c Eca109 cells-bearing mice model.To investigate whether CecropinXJ exert anti-tumor efficiency through regulating immune response when treated with tumor-bearing mice.Methods:The expression of cytokines and DC surface molecules were detected by immunohisto-chemistry and Flow cytometry.Results:The experiment of mice showed that CecropinXJ could significantly inhibit the proliferation of transplanted tumors in dose-dependent manner.There were significant difference between control group and 10mg/kg CecropinXJ group on the volume and weight of tumor ( P<0.05 ).CecropinXJ inhibited Eca 109 cells infiltrating growth in tumor tissue without affecting viscera,and the expressions of VEGF and bFGF proteins were higher than those in the control group .The expression of cytokines and DC surface molecules,the results that,compared with the control group,CecropinXJ could not significantly promote the expression of CD4,IL-4 and IFN-γ,while not involving the expression of surface molecules on DCs in spleen (P>0.05).In CecropinXJ treatment group,TNF-αlevel in serum was significantly higher than the control group ( P<0.01 ).Conclusion: CecropinXJ could significantly inhibit tumor growth in Eca109 cells-bearing mice,and might not be affected anti-tumor efficiency through regulating immune response.

Objective To explore the relationship between serum homocysteine (Hcy) level before coronary angiography(CAG) and contrast induced nephropathy (CIN) after CAG.Methods We included 2264 cases of suspected coronary heart disease from May 2013 to May 2016 and all patients received CAG examination.According to whether CIN has developed or not after CAG, the patients were divided into the non-CIN group (n=2162) and the CIN group (n=102).We analyzed and compared the clinical baseline data, serum Hcy and creatinine (Cr) levels and the estimated glomerular filtration rate between the 2 groups eGFR.Results Patients in the non-CIN group were younger and with less comorbidities of diabetes and chronic kidney disease (all P<0.05).The volume of contrast media consumed in the non-CIN group was less than the CIN group [(122±21)ml vs.(147±24)ml, P=0.012).Hcy level in the non-CIN group (12.81±6.71) μmol/L was lower than that in the CIN group (21.74±11.9)μmol/L before CAG (P<0.05).No significant differences in serum Cr level and eGFR before CAG (P>0.05).At 72 hours after CAG, Cr level of the non-CIN group (69.34±19.54 μmol/L) was lower than that of the CIN group (87.34±21.38) μmol/L (P<0.05).eGFR was higher in the non-CIN group (79.34±19.54)ml/min than that in the CIN group (67.34±21.38)ml/min (P<0.05).Linear regression analysis showed that Hcy level before CAG were positively correlated with Cr level after CAG (r=0.547,P<0.01) and negatively correlated with eGFR after CAG (r=-0.271,P<0.01).Conclusions Hcy level before CAG can be used as one of an effective parameter to predict CIN.

Objective Exploring clinical prediction value of the ischemia modified albumin (IMA) for acute coronary syndrome (ACS) patients after the percutaneous coronary intervention (PCI).Methods A total of 109 cases of the PCI postoperative patients of ACS at the Panggang General Hospital from January 2010 to July 2012 were included.IMA was determined within 6 hours after admission,and standardized treatment after PCI.After a 6-month follow-up,they were divided into the event group and non-event group according to cardiovascular events occurrence.Results 101 cases were followed-up,including 26 cases of cardiovascular events (25.74%) and 75 cases of no cardiovascular events (74.26%).The left ventricular ejection fraction of the event group [(45 ± 7)%] was significantly lower than the non-event group [(52 ± 10) %] (t =1.894,P < 0.05).Serum IMA of the event group[(105.51 ± 13.26) U/ml]was significantly higher than the non-event group [(85.18 ± 11.36) U/ml] (t =7.3518,P <0.01).After controlling other cardiovascular risk factors,IMA was still independent risk factors for cardiovascular events (OR =1.69,95% CI: 1.18 ~ 2.13,P =0.01).Conclusions IMA have very good clinical prediction value of cardiovascular events occurrence for ACS after PCI.
