Case teaching is one of the important means to improve teaching effect in the process of pharmacology teaching. According to the teaching object, teaching objectives and requirements to build one useful teaching case library about pharmacology, which can be used and shared for a long time, is the premise of case teaching in pharmacology. According to the actual situation of case teach-ing in our university, this study researched and explored the background of case library building, the basic principles of case compilation, the establishment of team, the teacher-led and the student-oriented processes of case building, and the process of sorting and summarizing cases in the case library build-ing, which promotes the reform in the pharmacology case teaching, improves teaching quality, and also provides a reference for other universities or schools and disciplines on teaching case library building.

Objective To evaluate clinical and procedural characteristics and outcomes of patients with ST-elevation myocardial infarction(STEMI) caused by drug-eluting stent(DES) thrombosis undergoing primary percutaneous coronary intervention(PCI).Methods From October 2004 to June 2007,31 patients with STEMI due to definite DES thrombosis who received primary PCI were retrospectively studied(ST group).Baseline clinical,angiographic,PCI procedural features and 1-year outcomes were recorded.Another consecutive 93 patients with STEMI due to de novo coronary thrombosis were served as control group.The primary endpoint was cumulative rate of major adverse cardiac events(MACE),including death,reoccurrence of myocardial infarction and target vessel revascularization(TVR),during hospitalization and at 1-year follow-up.Results Compared with the control group,patients in ST group were older(69.9?11.4 y and 63.7?13.6 y,P=0.01) and higher comorbidity rates of diabetes(41.9% and 22.6%,P=0.04)and previous history of myocardial infarction(29.0% and 11.8%,P=0.02).The occurrence of TIMI 3 flow immediately after primary PCI was reduced(45.2% and 92.5%,P

Objective To evaluate the clinical value of three-dimensional contrast-enhanced MR angiography (3D CE-MRA) in the diagnosis and treatment of aortic coarctation. Methods Twenty-one patients with aortic coarctation underwent 3D CE-MRA with a 3D FLASH sequence after injection of 0.2 mmol Gd-DTPA per kg b. w. The source images were subtracted and transferred to computer workstation subsequently post-procession. In six patients, cardioangiography was performed simultaneously. The diagnoses of all patients of them were proven by surgery. Results There were 6 cases (28.6%) of simple type of aortic coarctation and 15 (71.4%) accompanied other cardiovascular abnormalities. 3D CE-MRA could directly demonstrate the stenotic location, degree, extent and extracardiac vascular abnormalities, which accorded with surgical findings. The depiction of the entirety and collateral vessel formation was very helpful for surgery. It can be easier for pre- and post- operative evaluation. Conclusion 3D CE-MRA is a noninvasive and accurate technique in the diagnosis of aortic coarctation. It could replace the cardioangiography for extracardiac vascular abnormalities, and may be one of the first choice examinations.

Objective To study the effect of danshao shugan granule combined with metformin in treatment of nonalcoholic fatty liver and its effects on lipid and uric acid metabolism.Methods 80 patients of nonalcoholic fatty liver who received therapy from February 2014 to February 2015 in our hospital were selected as research objects.According to random number table,those patients were divided into the observation group (n=40) cases in each group and the control group (n=40).The control group was treated with metformin, while the observation group was treated with danshao shugan granule combined with metformin.Then blood lipid level, FBG, FINS, IR, SUA level, SOD, MDA level, therapeutic effect of two groups after treatment were compared.Results After treatment, TG,TC in observation group was significantly less than the control group (P<0.05); FBG, FINS, IR, SUA levels in the observation group were significantly lower than the control group ( P<0.05 ); SOD level higher than the control group, MDA level significantly less than the control group (P<0.05); The total effective rate of observation group was statistically higher than that in the control group (P<0.05).Conclusion Danshao shugan granule combined with metformin is well for nonalcoholic fatty liver,which can improve the glucose, lipid, uric acid metabolism and insulin resistance, and can protect the liver function.

Objective To perform calibration verification for the blood glucose test in Hitachi and Olympus automatic biochemistry analyzers and present a method of calibration verification and evaluate the results.Methods The glucose test results were divided into two groups:Hitachi and Olympus groups according to the different analytical instruments.The calibration verification was performed following the current College of American Pathologists strategies.The slope and intercept of the calibration line were tested by one-sample t test and the percentage differences were calculated.The percentage differences were compared with allowable errors.If the slope and intercept had no statistically significant difference from 1 and 0 respectively and the percentage differences were within the limits of allowable errors,the calibration line was evaluated as verified 1 ; if the slope and intercept had no statistically significant difference from 1 and 0 respectively and at least one of the percentage differences exceeded the limits of allowable errors,the calibration line was evaluated as different 1 ; if the slope or intercept had statistically significant difference from 1 and 0 respectively and the percentage differences were within the limits of allowable errors,the calibration line was evaluated as verified 2; if the slope or intercept had statistically significant difference from 1 and 0 respectively and at least one of the percentage differences exceeded the limits of allowable errors,the calibration line was evaluated as different 2.Results In Hitachi group,verified 1,different 1,verified 2 and different 2 were 5.4％ ( 4/74 ),0.0％ ( 0/74 ),68.9％ ( 51/74 ) and 25.7％ ( 19/74 ),respectively.In Olympus group,verified 1,different 1,verified 2 and different 2 were 16.4％ (12/73),0.0％ (0/73),58.9％ (43/73) and 24.7％ ( 18/73 ),respectively.Conclusions The current College of American Pathologist strategies could be performed as a reasonable and feasible method for calibration verification.Most of participating laboratories ( 74.8％,110/147 passed the assessment of calibration verification.

AIM:To research inhibitory effects of plumepoppy (Macleaya cordata) extract on dermophytosis. METHODS:A series of experimental methods,including agar hole method,plate dilution method and solid medium dilution method were initiated into pathogenic organism of skin disease,including Trichophyton rubrum(Tru),Trichophyton schoenleini(Ts),Trichophyton rosaceum(Tro),Trichophyton mentagrophytes(Tm),and Epidermophyton floccosum(Ep) to determinate in vitro antibacterial Minimum inhibitory concentration(MIC) by plumepoppy extract that macerated with acidic water (pH = 3). RESULTS:Macleaya cordata alkaloids had significant effect on these five kinds of skin fungi. The MIC of Tru,Ts,Ep was 1. 6 mg/mL; The MIC of Tro and Tm was 0. 8 mg/ mL. CONCLUSION:The plumepoppy extract has anti-fungus activaties,with the increasing concentration,the inhibition effect rapidly goes up.

The widely application of the radio knife alleviates the patient's pain and improve the medical quality.The radio knife is high frequency power equipment based on the theory that electricity concentrates on the skin.It can directly cut the tissue,homeostasis and cauterize.The safety requirement of this equipment is very strict because unsafe operation will burn the tissue,cause temporal unaware hurt and even endanger the patient's life.If the safety support system is imperfect,disastrous loss or medical conflict will be caused.Users must be cautious in using and familiar with the safety and protection of the radio knife.[Chinese Medical Equipment Journal,2008,29(2):96-98,104]
