According to the course character and training objective, we analyzed the necessity of the experiment teaching reform of microbiology examination . The modules of employable Skills (MES) was applied to the experiment teaching of microbiology examination tentatively. On the basis of the needs of microbiology laboratory jobs, the contents of experimental course were integrated and optimized to skills module , comprehensive training module and application module , which include fourteen study units such as basic techniques of identification of bacteria,the separation and identifi-cation of pathogenic bacteria, microbiology examination of clinical specimen etc. Intensive teaching and multiplex teaching methods were applied to each module according to the module's characteristic, teaching objectives and cognitive rules of students. This teaching reform has achieved initial results.

Objective To dynamically observe changes of IgG, its subclasses and IgE in sera of mice by immunization with mixed recombinant of BCG-Em Ⅱ/3 and BCG-Em14-3-3 vaccine of Echinococcus multilocularis (Era). Methods Forty Balb/c mice of 12-14 week old and 20-25 g weight were intranasally vaccinated by the vaccine, 4 mice were killed randomly by the weight on 0,2,4,6,8,10,12,14,16 and 18 weeks of immunization respectively, sera were gathered from the eyeball to measure IgG, its subclasses and IgE by routine ELISA. Results Levels of IgG, IgG2a and IgG2b in the sera of mice increased obviously on 2-18 weeks, reached the highest level on 10, 4 and 4 weeks respectively, the value was 0.095±0.033,0.022±0.001,0.023±0.003 respectively, as compared with the value on 0 week(0.030±0.013,0.012±0.004,0.013±0.004), the difference being statistically significant(q=2.95,4.87,2.81 respectively, P < 0.01 or P < 0.05); levels of IgG1, IgG3 and IgE in the sera of mice decreased remarkably on 2-18 weeks,came to the lowest level on 4,2,6 weeks respectively, the value was 0.031±0.004,0.136±0.002,0.114±0.002 respectively, as compared with the value on 0 week(0.192±0.007, 0.175±0.013,0.024±0.003), the difference being statistically significant (q =5.16,4.93,5.32 respectively, P < 0.01 or P < 0.05). Conclusion Helper T cell(TH) Ⅰ response is induced in mice by mixed recombinant of BCG-Em Ⅱ/3 and BCG-Em14-3-3 vaccine on early immunization.

Objective To investigate the protective effects and mechanism of shenmai injection(SMI) on cardiomyocytes injured by hydrogen peroxide(H 2O 2) or angiotension Ⅱ(AngⅡ). Methods According to the different concentrations of H 2O 2, AngⅡ,SMI,Vitamin C(VitC) added into the cardiomyocytes culture media(CCM), the cultures were divided into 15 groups. Lactate dehydrogenase(LDH ),malondialdehyde(MDA),superoxide dismutase (SOD) of CCM and cardiomyocytes viability(CMV), Na +-K +-ATPase,Ca 2+-ATPase?cardiomyocytes apoptosis rate(CMAR) ,nitrogen oxide(NO), nitrogen oxide synthesis enzyme(NOS),eNOS expression of cardiomyocytes were detected respectively .Results H 2O 2 or AngⅡ could decrease CMV, SOD, Na +-K +-ATPase,Ca 2+-ATPase,NOS,NO,eNOS expression and increase CMAR,LDH and MDA.SMI could lessen the changes of the items mentioned above ,which were caused by H 2O 2 or AngⅡ.The effects of SMI 10 ml/L were stronger than those of SMI 5 ml/L or VitC 50 mg/L.Conclusion SMI has a significant protective effect on cardiomyocyte injured by H 2O 2 or AngⅡ.

ObjectiveTo study the features of lower limb vein thrombus patients after spinal cord injury and the effects of thrombolysis therapy.MethodsWe practiced ultrasonography on 207 patients with lower limb swelling after spinal cord injury. ResultsAmong the 207 patients, 66 had thrombus, the positive rate was 31%: acute thrombus 58 cases, subacute thrombus 1 cases and chronic thrombus 7 cases. Conclusions Ultrasonography provides an important basis for the qualitative diagnoses of lower limb vein thrombus. It has certain clinical guiding effects in choosing methods of treatment.

In order to adapt to the requirements of the modern clinical laboratory to medical laboratory technology personnel operation ability,our hospital has modified professional microbiology experiment course to modular teaching from the traditional teaching mode.In the process of teaching experiment,the experiment course and clinical practice class are arranged,and the experiment course of microbiology is divided into five modules:basic skills,application,comprehensive training,extension,and clinical practice module.Basic skills module focuses on the foundation that students learn to observe the microbial morphology and master the basic operation technology,at the same time,cultivates the students' sterile ideas and biological safety;Application module pays attention to the detection of various types of bacteria,lets the student have as many times of trying as possible,battle-hardened;Comprehensive training module emphasizes students' ability of analyzing and resolving problems;Extension module guides students actively to make diffusing thinking and comprehensive analysis of problems;The final clinical practice module that combines theory and practice,further consolidates the basic operation skills,cultivates students' comprehensive ability,improves students' the independent working ability and professional thinking and habits.Five modules link up with each other closely and have progressive layers of the process.In sum,modular teaching motivates the students' interest in learning,solves the problem of students' insufficient operating ability,improves the teaching effect and provides a reform method for improving the quality of microbiological test experiment.

OBJECTIVETo explore the ultrastructural changes of hepatocyte fibrogenesis in cholelithiasis in biliary tract.
METHODSl0 liver biopsies were taken from the patients suffered from gallstone and choledocholithiasis during surgical treatment and the ultrastructural changes were observed under electromicroscope.
RESULTSThere were plentiful collagenous microfibrils (CMFs) grown within some hepatocytes. These CMFs distributed locally or diffusely in cytoplasm even extended into nucleus. In 7 cases numerous megamitochondrias appeared in several hepatocytes, the inclusions mimicking fibrils could be frequently seen and grew beyond the envelope. Furthermore, typical CMFs could be seen in the large microbodies, and several vesicular or cystic structures similar as fibroblast were presented in marginal areas of the hepatocytes.
CONCLUSIONSWe deduce that the fibrosed hepatocytes may be remained and take part in the hyperplasia of hepatic fibrous tissue.

OBJECTIVETo observe the efficacy of oral Propranolol in the treatment of infantile subglottic hemangioma.
METHODSEleven children (6 females and 5 males) with a median age at onset of treatment being 4 months were included in this study. Propranolol was given after laryngoscopy and a CT scan with contrast of the trachea confirming the presence of a subglottic hemangioma. The starting dose of Propranolol was 0.5 mg/kg per day, given in 2 or 3 divided doses. Heart rate and blood glucose were monitored during the treatment. If no side effects occurred, the dose was increased to 1 mg/kg per day at the third day and to 2 mg/kg per day at the sixth day. Treatment was continued at home after 10 days of inpatient treatment and the children were reevaluated monthly.
RESULTSAfter 24 - 48 hours of treatment, all of the children had improvement in their airway obstruction which was confirmed by fibro-laryngoscopy. The diameter of the subglottic stenosis from the hemangioma decreased from 3.9 - 5.0 mm to 1.5 - 2.0 mm,and the color was also lighter than before. In 3 children with cutaneous hemangioma, there was also significant improvement in the cutaneous lesions after treatment, with the color becoming lighter. There were no significant ECG, blood pressure or blood biochemical changes during the treatment. Two of the children had hypoglycemia at the first dose, but improved after blood transfusion and changing their diet. In five children, the treatment was stopped after 6 to 11 months when the obstructive symptoms improved. None of the children in this group had any evidence of recurrence. In the 5 children who stopped treatment, the obstructing mass in the subglottis was less than 10% of the diameter.
CONCLUSIONOral propranolol is a safe and effective treatment for infantile subglottic hemangioma. It may be used as a first-line therapeutic modality.
