Objective To study the relationship between serum lactadherin (MFG-E8),sialic acid (SA) level and coronary heart disease (CHD) occurrence and development.Methods 166 patients in our hospital were selected from June 2014 to November 2015,and then according to the result of coronary angiography divide the subjects into control group (n=56,the result of coronary angiography completely normal) and CHD group,including stable angina 48 cases (StA subgroup),unstable angina 30 cases (UA subgroup) and acute myocardial infarction 32 cases (AMI subgroup).The serum level of MFG-E8 was detected by ELISA method,the serum level of SA,hs-CRP and lipid index were detected by biochemical analysis.Gensini score showed the severity of coronary stenosis.The correlation analysis between detecting parameters was carried out by Spearman method.Results Compared with the control group,the patients with CHD have a higher level of serum SA and a lower level of MFG-E8 (both P<0.05).The AMI subgroup has a lower level of serum MFG-E8 than StA and UA subgroups,and the AMI subgroup has a higher level of serum SA than StA and UA subgroups (all P<0.05).The correlation analysis showed that the serum SA has a positively correlation with the level of TG,hs-CRP,and Gensini score,and has a negatively correlated with the level of MFG-E8 (all P<0.05).The MFG-E8 has a negatively correlated with the level of TG,hs-CRP,and Gensini score (all P<0.05).Conclusion MFG-E8 and SA play an important role in the development of CHD,and combined detection of serum MFG-E8 and SA may be helpful in the clinical diagnosis and risk assessment of patients with CHD.

Objective To analyze electrophysiology of peripheral nerve in uremic patients. Methods 24 uremic patients and 19 normalvolunteers were included, surface electrodes were used to observe the electrophysiology performance, including tibial nerve, peroneal nerve,sural nerve and skin sympathetic response. Results The motor conduction, sensory conduction and skin sympathetic response were significantlydifferent between uremia patients and normal volunteers (P<0.05). The electrophysiology performance showed that F wave latencyprolonged, nerve conduction slowed, distal latencies prolonged, sensory fibers damaged more serious than motor fibers. Conclusion Peripheralneuropathy is one of the most common complications in uremia patients, neural electrophysiological abnormalities are significantly earlierthan clinical symptoms, nerve electrophysiological examination is of great significance in diagnosis and evaluation uremic peripheralneuropathy.

Melamine is a kind of triazine compound and the fluorescence of it can get enhanced in the presence of cationic surfactant in weak alkaline medium. A new fluorescent spectrophotometry based on this principle) has been developed to determine melamine under the optimum conditions such as Tris-HCl buffer solution), pH 8.0 and with CTMAB as sensitizing agent. The linear range, detection limit and relative standard deviation were 25-1000 μg/L, 19 μg/L and 1.6%,respectively. The samples were pretreated according to the solid phase extraction monolithic column to carry out the detection of real milk. This method is simple, rapid and accurate. It can be used to screen and detect the milk samples primarily.

0.05). Conclusion IL-1? has a higher value than cagA gene in predicting the prognosis of chronic gastritis.

Purpose　To observe the killing effect of HSV-TK/GCV system on osteosarcoma cells. Methods　The eukaryotic exprssoin vector (tgCMV-HyTK) containing HSV-TK gene was transduced into human osteosarcoma cell lines SAOS-2 by DOTAP. Total RNA extracted from HSV-TK expressing cells (SAOS-2TK) were tested by RNA dot blot analysis. A chemosensitivity of SAOS-2TK cells to GCV and “bystander effect” were measured by means of MTT colrimetric assay. Results　HSV-TK gene was expressed in SAOS-2TK cells. SAOS-2TK cells were susceptible to the cytotoxicity of GCV. A meaningful “bystander effect” was demonstrated. Conclusion　HSV-TK/GCV system may kill selectively the human osteosarcoma cell line SAOS-2.

Objective: To investigate the effects of selenium containing polysaccharide from Ganoderma lucidum on SOD, GSH Px activity, MDA content in blood and liver and anti tumor effect in tumor bearing mice, and relationship between antioxidative and anti tumor effect. Methods: The tumor bearing BALB c mice were injected with 2.5 g/L? 5.0 g/L and 10.0 g/L SeGLP 1 respectively for 14 days. Weight of tumor, both SOD and GSH Px activities and MDA content of blood and liver were determined. Results: SeGLP 1 could significantly inhibit the growth of Hca f, maximal inhibition rate was 44%, SeGLP 1 significantly increased SOD, GSH Px activity, decreased MDA content of blood and liver in tumor bearing mice. Conclusion: The anti tumor effect of SeGLP 1 may be due to enhanced antioxidative capacity in tumor bearing mice.

AIM: To investigate killing effect of herpes simplex virus thymidine kinase/ganciclovior system(HSV-TK/GCV) on osteosarcoma cell and its mechanisms.METHODS: Recombinant retroviral vector (DORHyTK) containing hygromycin phosphotransferase-thymidine kinase fusion gene(HyTK) was constructed and introduced into human osteosarcoma cell line OS732 with DOTAP. DNA and total RNA extracted from HyTK expressing cells (OS732TK) were tested by PCR and RNA dot blot analysis. A chemosensitivity of OS732TK cells to GCV and “bystander effect” were measured by means of MTT colorimetric assay. Hoeschst 332258 staining and flow cytometric analysis were performed for mechanism of HSV-TK/GCV system gene therapy. RESULTS: DORHyTK was constructed successfully; the HyTK gene existed and expressed in OS732TK cells; All OS732TK cells were killed after 5 days of exposure to 5 mg/L GCV. The “bystander effect” was observed in both a high population and a low population, but the former was stronger than the latter. Hoeschst 332258 staining revealed the characteristic hallmarks of apoptosis, however necrosis also existed. Flow cytometric analysis of DNA content showed a G0-G1 phase blockade. CONCLUSION: HSV-TK/GCV gene therapy system showed its strong killing effects on osteosarcoma cells OS732; The phenomenon of “bystander effect” was also very apparent. GCV exposure induced both necrotic and apoptotic death in HSV-TK expressing cells, and perturbed the cell cycle. HSV-TK/GCV gene therapy system may provide a new therapeutic approach for treatment of osteosarcoma.
