Objective To clone human neural RNA binding protein HuC cDNA,express and purify the recombinant human HuC(Hu antigen C)protein in E.coli.Method Human HuC cDNA was cloned by RT-PCR.HuC cDNA was inserted into the prokaryotic expression vector pGEX-4T-3.The recombinant protein HuC was expressed in E.coli BL-21,and purified by the GST Sepharose 4B affinity column.Results The(62 ku) recombinant GST-HuC fusion protein was obtained.Conclusion The recombinant human HuC protein was successfully prokaryotic expressed and purified.

Objective: To study the clinical role of the variation of serum matrix metalloproteinase-8 (MMP-8) concentration in patients with acute coronary syndrome (ACS). Methods: ELISA method was adopted to detect serum MMP-8 concentration and to observe concentration's differences and features among 80 selected ACS cases (43 acute myocardial infarction and 37 unstable angina pectoris), 43 stable angina pectoris (SAP) cases and 37 control cases. And meanwhile the atherosclerosis risk factors of each case, such as age, sex, hypertension, body mass index, smoking, family history, diabetes, and hyperlipidemia were collected and analyzed as a whole. Results: First, serum MMP-8 concentration reached the highest point in ACS, and there was significant difference between SAP and control groups (P<0.01). Second, serum MMP-8 in AMI was much higher than that in UAP with significant difference (P<0.01). There was no difference between UAP and SAP groups (P>0.05). Third, Logistic regression analysis revealed that serum MMP-8 concentration might be the indicator of ACS (B=4.493, P=0.000), particularly, that of AMI (B=9.961, P=0.000). Fourth, linear correlation and linear regression analysis found that only neutrophil was likely to influence serum MMP-8 concentration (r=0.274, P=0.001). Fifth, in the diagnosis of ACS, the area under ROC curve of MMP-8 was 0.785, the sensitivity and specificity were 68.6% and 76.5%, respectively. Conclusion: 1 Serum MMP-8 concentration has close relationship with the occurrence of ACS, particularly with AMI; 2 Serum MMP-8 concentration may be one of the predicting indicators of ACS and particularly of AMI; 3 Neutrophil may be correlated with serum MMP-8 concentration; 4 MMP-8 is of somewhat valuable in diagnosing ACS.

Objective To explore the relationship of human cytomegalovirus(HCMV) infection and infantal epilepsy.Methods Fluorescence quantitative polymerase chain reaction was employed to detect the urine HCMV-DNA in 20 healthy children and 52 infants with epilepsy,and the changes in head CT scanning and brainstem auditory evoked potential were determined in HCMV positive and negative epilepsy infants.Results Positive HCMV-DNA was found in 31(59.62%)infants with epilepsy and 6(30%)healthy infants,there was significant difference between two groups(P
