To attach importance to practice teaching in clinical microbiological analysis,the overall planning,research-on-research and systematic training must be carried out.

Objective The study discussed the underlying mechanism of the impact of perceived social support on individual learning behavior from the perspective of the psychosocial impact theory .Methods 224 students majored in public management were involved ,and the dada was collected by questionnaires ,then the conceptual model was tested by moderate effect sequence of statistical analysis .Results The findings were as follows :Firstly ,perceived social support had a significant effect on individual learning behavior (β=0 .332 ,P<0 .01) .Secondly ,the relationship between perceived social support and individual learning behavior was moderated by self efficacy (β= -0 .216 ,P<0 .01) .Conclusion Perceived social support and self efficacy have moderate effect on individual learning behavior .

Objective To make an investigation for autoantibodies detection in China. Method Forty-eight hospitals were included by mail or Email. The items of QC include ANA, anti-ENA antibody, anti-dsDNA antibody, anti-mitochondria antibody and anti-smooth muscle antibody. The distribution of samples and analysis of the testing results was double-blinded. Result The correct rate of ANA, anti-ENA antibody, anti-dsDNA antibody, anti-mitochondria antibody and anti-smooth muscle antibody were 47%, 70%, 46%, 95%and 40% respectively. Conclusion The overall results are not optimistic. The quality of detecting kits is not all good, neither level of technicians. This condition should be changed by selecting better methods and improving understanding.

Objective To analyze the outcome of patients with acute obstruction of left colorectal cancer treated by modified antegrade colonic lavage with primary tumor resection and anastomosis.Methods From April 2002 to April 2007,112 patients with acute obstruction of left colorectal cancer underwent surgery.During the operation the left colon was exteriorized and placed into a sterilized plastic bag to protect the surgical field from contamination,then a catheter was inserted via the appendix,and after antegrade colonic lavage,primary resection and anastomosis was performed.Results Tumor resection and primary anastomosis was successfully done in the 112 cases.Postoperatively,1 case had anastomotic leak which healed after reoperation with proximal colostomy,and one patient died.Conclusions Modified antegrade colonic lavage is a simple procedure,the bowel can be rapidly decompressed with essentially no contamination,and has a high level of bowel cleansing.It is possible to safely perform primary resection and anastomosis for left colon cancer after the modified antegrade lavage.

Objective To establish HPLC assaying methods for the determination of albiflorin in the Jinsha-Paishi infusion, and to determine the content of albiflorin of different batches ofJinsha-Paishiinfusion. Methods The chromatographic conditions were with the column of C18 (250 mm × 4.6 mm, 5μm), mobile phase of methyl alcohol-aqua (25:75,V/V), flow rate of 1.0 ml/min, and determined at wave length of 230 nm in room temperature. A total of 3 different batches of albiflorin were determined.Results In the range of 2.5-200μg, the distribution of paeoniflorin was linear (r=0.999 8), and theRSD of precision, stability and repeatability were less than 2%. The average recovery was 98.05%, andRSD was 1.65%. The contents of albiflorin in each batch were 0.080, 0.083, 0.077 mg/g.Conclusion The assaying method of HPLC is convenient, accurate and reliable to determinate the content of albiflrin in theJinsha-Paishi infusion. And the results showed that there was no difference of content of albiflorin among the different batches ofJinsha-Paishi infusion.

Objective:To evaluate mental health status of medical students and to explore its related factors.Methods:877 medical students were tested by Symptom Checklist(SCL-90),Simplified Coping Style Questionnaire(CPS),and the stressful events items;240 of them were tested by Eysenck Personality Questionnaire (EPQ).Results:①Compared with the SCL-90 norm of youth group,medical students had higher scores ( P

Objective To establish the optimal section planes for observing ventricular septal defect(VSD) by real-time three dimensional echocardiography(RT-3DE).Methods In 6 pig hearts with different types of VSD, after high pressural perfusion with coupling reagent, two dimensional, dual plane and RT-3DE were performed with different section planes, estimating with half quantificational visional grade:4 marks,very clear;3 marks,clear;2 marks,not clear enough; 1 marks,not clear. Results Observation by RT-3DE, en-face view of atrial-ventricular(S2a) and en-face view of left ventricular septum(L1a) provided relatively ideal section planes in sub-arterial ventricular septal defect, S2a and en-face view of right ventricular septum(L2a) provided relatively ideal section planes in perimembranous and muscular VSD. Conclusions S2a reflects relatively ideal section plane in sub-arterial, perimembranous and muscular VSD.

Objective To investigate clinical effects of transurethral resection of bladder tumor (TURBT) combined with postoperative perfusion of mitomycin C to urinary bladder on superficial bladder cancer. Methods 32 patients with superficial bladder cancer were treated by TURBT and discontinuous perfusion of mitomycin C (20mg/20ml) to urinary bladder. Results 32 cases of the superficial bladder cancers all were once ablated. 8 cases relapsed in 6 months to 2 years of postoperation, which were treated by TURBT and discontinuous perfusion of mitomycin C to urinary bladder again, and relapse was not found from postoperation to present. Conclusions Treatment of TURBT combined with perfusion of mitomycin C on superficial bladder cancer is repeatable, simple, safe and effective.

miR-320 is a newly discovered microRNA .In recent years, the abnormal expression of miR-320 has been found in various kinds of tumors .Therefore, its function and molecular mechanism in the tumorigenesis and tumor progression has getting more and more attention .
