On base of routine treatment, the treatment group was treated with Tianzhi Granules orally; and the control group was treated with Duflomed Hydrochloride orally. One course of treatment was 14 days. Results The total effective rates were 96.77%and 78.57% in treatment group and control group respectively. There was a significant difference between the two groups(P<0.05). The blood flow rat(BFR)of brain was improved in both groups, but the improvement of the BFR in brain was significantly better in the treatment group than the control group (P< 0.05). No adverse reaction was found in the treatment group. Conclusion Tianzhi Granules is effective and safe in treating Vetigo due vertebrobasilar insufficient blood supply.

Objective To analyze the radiological images of osteonecrosis in rare positions in recovered SARS patients, and to study the correlation with the hormone application.Methods The extremities of 41 SARS patients in the recovery stage from June to August in 2003 were examined by using X-ray and 0.5T MR scanner, then the correlation of MR examination results and the application of hormone was analyzed.The mean time interval between the imaging examination and initial hormone application was 88.2 days (66～106 days), the mean maximum hormone (metastab) dose was 392 mg (320-480 mg), and the average medication time was 47.2 days (30-70 days).Results The osteonecrosis of rare positions was revealed in 5 cases involving 11 positions, including bilateral heads of humerus (3), right scaphoid bone (1), right talus (1), bilateral calcaneus (1), and right ischium (1).The main MR manifestation was irregular abnormal signal.Osteonecrosis of right ischium was demonstrated on plain film in only one case.Conclusion MR examination, especially the multi-location scan is necessary in finding the osteonecrosis in SARS patients in the earlier phase.The hormone dose, the medication duration, the sensitivity to hormone, and the difference of individuals are important causes of osteonecrosis.

OBJECTIVE: To study the status quo and features of serious ADR case in our hospital in order to improve the rational use of drug. METHODS: A total of 215 cases of serious ADR collected in our hospital in 2008 were evaluated and analyzed statistically, according to causality of ADR criteria. RESULTS: Sex and age have nothing to do with serious ADR. The ADR were predominantly induced by antimicrobial drugs accounting for 28.21% (n=101), followed by antipyretic,analgesics and anti-inflammatory drugs and antirheumatic 12.85% (n=46) and TCM preparation 11.73% (n=42). Organs and systems involved in ADR were characterized by the damage of skin and its appendants (33.49%, n=73), followed by liver lesion in 70 cases (32.11%). 160 improved cases, 54 cured cases and 1 sequela cases were include in 215 cases of serious ADR reports. CONCLUSION: Several factors result in serious ADR,so rational use of drug should be enhanced to reduce and avoid occurrence of ADR and guarantee the safety and effectiveness of drug therapy.

Objective To investigate the effect of Bushen-Tongmai decoction on plasma renin activity (PRA), plasma levels of brain natriuretic peptide (BNP) and angiotensinⅡ(AngⅡ) in patients with chronic heart failure. Methods A total of 100 patients with chronic heart failure from January 2011 to December 2013 were randomly divided into a control group and a treatment group, with 50 patients in each group. The patients in the control and treatment groups received conventional treatment and Bushen-Tongmai decoction plus conventional treatment for 8 weeks, respectively. Laboratory measurements including PRA, BNP and AngⅡwere performed before and after treatment.Cardiac function was measured before and after treatment with echocardiography. Results The PRA , plasma levels of BNP and AngⅡ after treatment in the treatment group were significantly decreased than before treatment (treatment group:t=2.990, 4.030, 4.401, all P<0.01);after treatment, there was significant difference in PRA, BNP and AngⅡbetween the treatment group and the control group(t=2.622, 2.863, 3.809, all P<0.05). Left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD) and left ventricular ejection fraction (LVEF) by echocardiography in both groups were significantly improved (treatment group:t=9.167, 11.030, 13.273, all P<0.01;control group:t=5.189, 7.626, 6.906, all P<0.01). Improvements of LVESD, LVEDD and LVEF in the treatment group were grater than those in the control group (t=4.037, 2.701, 7.458, all P<0.01). Conclusion Bushen-Tongmai decoction can effectively decrease PRA , plasma levels of BNP, AngⅡ, and improve cardiac function in patients with chronic heart failure.

Objective:To verify the effects of microlecture based on robot carrier on standardized residency training of orthopedics.Methods:Sixty orthopedic residents from our hospital were divided into two groups according to different training methods. One was control group ( n = 30), receiving regular training methods, and the other one was experimental group ( n = 30), receiving additional microlecture based on robot carrier besides regular training methods. The teaching effects of the two groups were compared after the training in orthopedics department. SPSS 20.0 was used for t test. Results:There was no significant difference between the experimental group and the control group in theoretical tests results [(88.63±10.24) vs. (87.85±9.62), P > 0.05]. The operation test scores in experimental group (92.12±7.52) were significantly better than that in control group (85.35±8.12), with statistical significance ( P < 0.05). The satisfaction scores for teaching in experimental group (90.00%) was significantly higher than that in control group (70.00%) ( P < 0.05). Conclusion:Microlecture based on robot carrier could enhance abilities of skills operation for orthopedic residents during the standardized residency training and improve their satisfaction for the teaching effect.

Objective To understand the basic experimental teaching of functional science in order to promote transformative learning. Methods Random sampling questionnaire survey was con-ducted among 274 students (2011 grade, 5-year-program) majored in clinical medicine, medical lab-oratory and medical imaging in Kunming Medical University. Investigation primarily aimed at the stu-dents' learning attitude, learning objectives, and teaching content. Excel 2003 was used for data en-try, percentage of each questionnaire option was calculated and the findings were directly described. Results 94.76%(253/267) students preferred basic experiment; 82.40%(220/267) students hoped to open long term laboratory;97.38%(260/267) students thought that basic experiment could help pro-mote understanding and theoretical knowledge of physiology; 98.50%(262/267) students thought the explain of the basic theories and the operation prior to each experiment were good; 78.27%(209/267) students were willing to strengthen the basic operation while only 59.18%(158/267) students would like to analyze the experiment results. Conclusions Basic experiment of functional science is wel-comed by students. Due to the lack of independent thinking ability of students, experiment course should de designed to promote interest-oriented transformative learning and to culture transformation perspective, finally achieving the transformative learning.
