SPSS was performed for data analysis, and the teaching effect was evaluated through the data results.Results:The scores of 108 students in the study [(75.99±5.76) points] were roughly distributed as normal functions. The results of the survey showed that the number of students who planned to have their own private clinics after the course increased by 41 (37.96%) compared with that before the course. All instructors and 33 (78.57%) active dentists thought that the course was reasonable in the undergraduate courses.Conclusion:It is necessary and feasible to introduce the dental practice management course in undergraduate education of stomatology, which will have a certain guiding effect on the long-term development of dentists, and is also beneficial to the reform of innovation and entrepreneurship courses in medical universities.

The present study was performed to establish the UPLC fingerprints of Bolbostemmatis Rhizoma and determine the contents of three saponins by quantitative analysis of multi-components by single marker(QAMS), and provide basis for quality evaluation of Bolbostemmatis Rhizoma. The analysis was carried out on an analytical column of Waters Cortecs T3(2.1 mm×100 mm,1.6 μm)with gradient elution by acetonitrile-0.1% phosphoric acid solution, at a flow rate of 0.3 mL·min~(-1). The detection wavelength was 203 nm, the column temperature was 30 ℃ and the injection volume was 1 μL. The UPLC fingerprints of Bolbostemmatis Rhizoma were established and evaluated by similarity calculation, cluster analysis and principal component analysis. The relative calibration factors of toberoside B and toberoside C were determined with toberoside A as internal reference. The content was calculated by relative calibration factors to develop a method of QAMS. Comparing the results of QAMS with those of ESM, the accuracy and feasibility of one-eva-luation and multi-evaluation can be determined. RESULTS:: showed that the fingerprints of 19 batches of Bolbostemmatis Rhizoma have four common peaks with similarities ranging from 0.754 to 1.000. Cluster analysis and principal component analysis classified 19 batches of Bolbostemmatis Rhizoma into three categories, which was consistent with the similarity evaluation results. The relative deviation between the content of tubeicosides B and C in 19 batches of Bolbostemmatis Rhizoma determined by QAMS and ESM is less than 5.0%, indicating that there was no significant difference between the two methods. Therefore, the UPLC fingerprints combined with QAMS and similarity evaluation can be effectively used to evaluate the quality of Bolbostemmatis Rhizoma.

Objective: To investigate the shortage of emergency medicines in emergency department of 76 medical institutions in China, and find out the reasons and the measurements. Methods: The shortage of emergency medicines in 76 class-Ⅰ, class-Ⅱ and class-Ⅲmedical institutions from 22 provinces, autonomous regions and municipalities across the country was investigated by question-naires, and the data obtained from the survey were collected and analyzed by Excel 2007. Results: Totally 76 questionnaires were sent out, and all of them were recycled with the effective recovery of 100% . Pralidoxime chloride injection ranked the first in 59 investiga-ted medicines with the shortage rate of 63. 16% , which was at the top spot in the list of the different medical institutions as well. The main reasons of drug shortage were as follows: less clinical requirements, lost-bid in centralized bidding and price inversion. Conclu-sion: It is suggested that the relevant management departments should establish a reasonable pricing mechanism and carry out policy guarantee for the urgent need of emergency medicines with low dosage and low price.

Objective To investigate the current status and features of the use of medical resources for emergency patients with medical insurance in China clarified by analysis of large numbers of data.Methods Using the database from China Medical Insurance Research Association's research group,the total amount and the average cost of emergency medicines for patients with medical insurance,as well as the proportion of emergency medicines in total medical resources used in the emergency department were statistically analyzed.Additional analyses were made based on cities and medical institutions of different levels.Results The data were collected from more than 63 million pieces of medication information,from which 260 thousand pieces of information involved in emergency medicine used within 100 sorts of emergency medicines.The use of emergency medicines for emergency cases accounted for a low proportion of over all medicine used in emergency department in our country,and the specifications of emergency medicine were limited in a few kinds of medicine such as tetanus antitoxin injectio (1500 U),50％ glucose solution in 20 ml water,and 50 g mannitol in 250 ml water frequently used as the leading essential agents.The sum of consumption of emergency medicines in tertiary hospitals was the highest among all levels of medical institutions,and the proportion of which in all medicine used in the emergency department also in the first place of the list.In the third-tier cities,although the sum of consumption of emergency medicines accounted for a small proportion of the whole country,the proportion of which in all kinds of medicine used in the emergency department was highest,while the situation of first-tier cities was just on the contrary.Except for only a few medicines,the ranking of the use of any emergency medicine else varied little in different cities and in various medical institutions.Conclusions On one hand,the current status and characteristics of the use of emergency medicines for emergency patients with medical insurance in China may be related to the characteristics of emergency departments and emergency cases,and on the other hand,they could also be influenced by medicines in clinical needs,clinical compliance,and shortages.This study showed the clinical application of emergency medicines in China in the past three years,which can provide some clinical data for the revision of emergency drug list in the future.
