0.05).② On diagnosing ACS,the area under ROC curve of sCD40L was 0.773,the sensitivity,specificity and validity are 82.8%,61.9% and 85.7%,respectively,which were all highest among so much indexes.Conclusion High serum sCD40L levels may suggest vulnerable plaque,and it's somewhat valuable in diagnosing ACS.

Objective The gene encoding part of HTLV(Human Tcell leukemia viruses) envelope protein gp21 was cloned and expressed in order to prepare diagnostic agent for detecting HTLV.Methods The gene encoding part of HTLV envelope protein gp21 was obtained by combining four oligonucleotides into a long DNA fragment,then cloned and subcloned into Tvector and pGEX2T respectively.Expression was performed under induction in a fusion way that target protein gene was inserted downstream the carrying protein gene of pGEX2T which makes purification of target protein convenient.At last,Target protein was purified by affinity chromatography in glutathione sepharose 4B column and its antigenicity was confirmed by immunoblotting.Results and conclusion Sequence analysis showed it was feasible to obtain a target gene by ligating short oligonucleotides;As expected,target protein was expressed which exhibited strong antigenicity after being subcloned into fusion expression vector pGEX2T.

In order to change the situations such as students’passivity and low enthusiasm in the traditional experimental teaching of Microbiology and improve students’comprehensive qualities,exploration and attempt on experimental teaching reforms including teaching contents,teaching modes,laboratory management and evaluation system of examination were done.Teaching practices showed that the normalized ex- periment syllabus based on the correct orientation of experimental teaching of Microbiology,the actualization of teaching mode of basic skill training-integrated experiment-designed experiment and the management of opening laboratory were effective measures in improving experimental teaching of Microbiology.

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, sermn 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.

In this study, three methods for identification of E.coli were compared. The conventional method was employed to select and identify the suspicious E.coli isolates from a fecal sample. PCR based ARDRA analysis was then carried out to distinguish these E.coli isolates, E.coli MG1655 and other bacterial species. All the potential E.coli isolates and E.coli MG1655 had the identical ARDRA banding pattern while the other bacterial species showed the different patterns.The result indicated that the ARDRA analysis was consistent with the traditional method for identification of E.coli and could be the practical method for distinguishing E.coli from other intestinal bacterial species. The ERIC-PCR analysis provided abundant polymorphism between different E.coli isolates, and might be a powerful approach for elucidating the genetic diversity among isolates of the same species.

Objective To explore quality of life and coping style of autistic children' s parents, and correlation between them. Methods 68 parents of children with autism and 64 healthy children' s parents were tested with comprehensive assessment questionnaire of the quality of life and coping style questionnaire. Data were analyzed by t -test and multivariate regression analysis. Results The scores of material life and mental health dimensions in study group(48.18 ± 12.80,60.63 ± 10.18 ) were lower than that in control group(52.71±9.84,65.79±8.64) and the difference was significant( t= -2.04, P<0.05; t= -3.09, P<0.01 ). The scores of "problem solving" coping style in study group were slower than in control group; the scores of fantasy and wincing coping style in study group were higher than that in control group. By multivariate regression analysis showed that the scores of "problem solving" coping style were positively correlated with total score of life quality,physical health,mental health and social function dimensions; the scores of "fantasy" coping style had negative correlation with the total score of life quality; the scores of "wincing" coping style had negative correlation with mental health dimension. Conclusion Parents of autistic children were more susceptible to problems of physical life and mental health. Compared to parents of normal children they are more in "fantasy and wineing style and less in" problem solving style to cope with stress, so it would affect the quality of life and mental health badly and need early intervention.
