Objective This study aimed to accurately understand medical teaching design research status and development trend to provide practical basis for the future of the medical teaching practice.Methods CNKI academic journal articles from January 1,2000 to December 30,2013 were retrieved,using search item for the subject,the retrieval word for instructional system design or instructional design,and the retrieval subject for medicine,and matches are precise retrieval way,and a total of 298 articles were retrieved.The common word analysis method was used to compare the high frequency keywords,analyze the key words in the article,and study the high frequency keywords clustering.Results In the two stages from 2000 to 2006 and from 2006 to 2013,research on medical teaching design of the courseware,distance education and other traditional E-learning-frequency gradually reduced,and vocabulary frequency related to education informationization of new situation such as cooperative learning,teacher education and constructionism and so on increased.In addition,in the second stage,some fresh words related to new technologies and new media appeared,such as interactive electronic whiteboard,virtual reality technology and so on.According to the correlation of keywords in 2007-2013,we found that the current medical teaching design research mainly gathered in three aspects such as classroom teaching,information technology supporting the reform of medical teaching and the training of medical teaching practitioners.Conclusion The research concluded that today and the future of medical teaching design research will mainly focus on three aspects such as effective teaching,the diversification of teaching supported by information technology and open medical education research under the Internet environment.

Objective To investigate the clinical efficacy of B-Lynch suture in the treatment of massive hemorrhage during cesarean section. Methods Thirty-six patients with massive hemorrhage during cesarean section were applied with B-Lynch suture when bleeding was not controlled through conventional treatment. Results The bleeding of 36 cases were all controlled effectively when treated with B-Lynch suture,no one was operated again because of poor blood circulation or rebleeding, avoided hysterectomy, no postoperative complications occurred, there was no abnormal of uterine involution and the menstrual time.Conclusions The operation of B-Lynch suture is easy, hemostasis rapidly,reliable,persistently,and with high success rate. It can reserve the uterus maximumly, reserve the fertility function of the patient. It is the effective surgical hemostasis in the treatment of massive hemorrhage during cesarean section, and without special equipment, suitable for primary hospital use when emergency,worthing promotion.

OBJECTIVE:To establish a method for dissolution determination of Erythromycin ethylsuccinate granules.METHODS:Paddle method was adopted and 0.1 mol?L-1 HCl solution was used as dissolution medium at rotation rate of 50 r?min-1.UV spectrophotometry was used to detect at wavelength of 482 nm.Dissolution rate was calculated.RESULTS:The linear range of erythromycin ethylsuccinate were 4～40 mg?L-1(r=0.999 0,n=5)with an average recovery of 99.19%(RSD=0.56%).Dissolution rate of erythromycin ethylsuccinate was more than 80% within 30 min.CONCLUSION:The method is rapid,simple and accurate for the quality control of Erythromycin ethylsuccinate granules.

Objective To establish the method of content determination of Berberine in Zhenjing San. Method The analysis was carried out on C18 column (4.6 mm?250 mm, 5 ?m) by HPLC. The mobile please was acetonitrile-0.033 mol/L KH2PO4 (22∶78), the flow rate was 0.800 mL/min and detective wave length was 345 nm. Result The cabibration curves showed good linearity in the range of 12.012～600.600 ?g. The average recovery was 98.85% (RSD=1.09%). Conclusion The method is good sensitive, accurate and reliable.

Objective To explore the curative effect of dissection steel plate treatment in humerus near end bone fracture curative effect.Methods From June 2000 to March 2006,dissection steel plate treatment was used in 31 cases of humerus near end bone fracture and Constant-Murley scores was used to evaluate the curative effect.Results All patients were made a follow-up for 10 to 24 months,the average 16.5 months.31 examples surgeries patient only superior 16 examples,good 10 examples,may 2 examples,difficult 3 examples.Conclusion Center 3 and 4 humeruses near ends bone fracture uses the dissection steel plate treatment to Neer dividing will be possible to obtain the good clinical effect.

Objective To evaluate the value of liver acquisition with volume acceleration(LAVA) in the diagnosis of hepatic outflow abnormalities.Methods LAVA was performed in 78 patients with suspected hepatic outflow abnormalities,thrombosis,stenosis,occlusion,or compression,including 71 hepatocellular carcinomas and 7 Budd-Chiari syndrome.Image quality and the presence of venous abnormalities and collaterals were evaluated.Results LAVA images were of diagnostic quality and without artifact in all patients.LAVA clearly showed the vascular anatomy and various disorders.The site,extent,cause of venous obstruction,and collateral pathways were well depicted.Conclusion LAVA is simple to perform and accurate in detecting hepatic outflow abnormalities.

OBJECTIVE: To explore the correlation among platelet activation, inflammatory factor changes and vascular restenosis following intravascular stent implantation.METHODS: Chinese Journal Full-Text Database and Pubmed were retrieved using search terms of intracranial arterial, stents,stenosis, elevated platelet activation, and inflammatory factors from January 1999 to June 2009. The language was restricted within Chinese and English. Simultaneously, platelet activation and inflammatory factor changes were acted as evaluation indexes. Accordingly, clinical research regarding treating intracranial artery stenosis with intravascular stent implantation was included. The animal experiment or other treatment methods were excluded.RESULTS: A total of 650 papers were obtained by initial search with computer. According to inclusion criteria, the related papers were analyzed. Platelet activation, inflammatory reaction and inflammatory factor were the focuses of research concerning restenosis following intravascular stent implantation. Platelet thrombus was the main factor to cause acute vascular occlusion, and the activated platelet aggravated the damage of endothelial cells, which induced over proliferation of smooth muscle cell. As a kind of foreign body, the stent implantation was closely associated with complication, such as formation of thrombosis, acute vascular occlusion, vasovagal reflex and immune reaction, which lead to reconstruction of vessel wall and in-stent restenosis.CONCLUSION: It is effective to cure vascular restenosis by undergoing antiplatelet therapy prior to implantation, controlling inflammatory reaction, as well as inhibiting vascular smooth muscle cell proliferation following intravascular stent implantation.

Seven cases exhibited segmental bile duct dilation with filling defects. One case only showed dilatation of lobar bile ducts. Conclusion MRI features of IPNB are helpful for distinguishing IPNB from other hepatic lesions.

Oral mucositis is a common and serious complication secondary to chemo-radiotherapy for head and neck cancer that has a high morbidity and affects the treatment outcomes. Currently available interven-tions such as three-dimensional conformal radiotherapy and intensity-modulated radiation therapy are directed at minimizing local radiation exposure and providing symptomatic relief. Recently, a number of new treatment mo-dalities have been expected to be introduced for reduction of severity and duration of mucositis, such as kerati-nocyto growth factor, amifostine, zinc sulfate,anti-inflammation agents,glutamine,etc. These efforts are likely to improve the life quality of cancer patients significantly.

Resveratrol has several neuroprotective effects in cerebral ischemia, including reductions of oxidative stress, inflammatory responses and apoptosis. Recent studies have shown that these neuroprotective effects of resveratrol may be involved in activation of silent information regulator 1.
