ABSTRACT
Teaching level is the core of teaching quality monitoring.Students' feedback to the quality ofteaching will help teachers to reflect and rectify the related factors of their teaching,so as to achieve the purpose of improving teaching quality.We have always insisted on doing this work.However,there are inconveniences in the "paper version" of the survey:complicated preparations and operations,inconvenient storage,and labor and material costs.Combined with the actual situation in our department,we are trying to reform and explore the digital survey for teaching quality ofhuman parasitology.Teachers will put the issue on the network,students can evaluate it at anytime,anywhere,and the platform automatically organize the information and quickly feed back to the teachers.The novel and effectiveway has been well received by students and teachers.
ABSTRACT
PURPOSE: This study aimed to create a digitized database of fabricated obturators to be kept for patients' potential emergency needs. MATERIALS AND METHODS: A chairside intraoral scanner was used to scan the surfaces of an acrylic resin obturator. The scanned data was recorded and saved as a single standard tessellation language file using a three-dimensional modeling software. A simulated obturator model was manufactured using fused deposition modeling technique in a three-dimensional printer. RESULTS: The entire obturator was successfully scanned regardless of its structural complexity, modeled as three-dimensional data, and stored in the digital system of our clinic at a relatively small size (19.6 MB). A simulated obturator model was then accurately manufactured from these data. CONCLUSION: This study provides a proof-of-concept for the use of digital technology to create a digitized database of obturators for edentulous maxillectomy patients.

ABSTRACT
A digitized hospital is one with network management as its basic mode, information as the primary driving force of its development, information technology as a prop to enhance its technological strength, information culture as a way to change the ways of peoples education and work and their ideological concepts, and construction of information systems as a new growth point of its advancement. While construction of digitized hospitals is a natural trend of historical development and is presently viable, construction of information systems in domestic hospitals must be based on Chinas realities so as to build digitized hospitals with Chinese characteristics. In light of their hospitals experience in building itself into a digitized hospital, the authors point out that it is necessary to formulate in the first place an overall objective in view of the requirements of digitized hospitals and then proceed step by step according to plan.

METHODS: The chromatographic fingerprints were obtained by injecting 20 ?L of the sample solution each time on a Century SIL BDS column (250 mm?4.6 mm, 5 ?m) with the gradient elution solvent system composed of 1% acetic acid water and 1% acetic acid acetonitrile. The flow rate was 1 mL/min, the column temperature was maintained at (30?0.15)℃ and the detection wavelength was set at 265 nm. The chromatographic fingerprints were charateristically digitized and evaluated by the software of the digitized evaluation system of traditional Chinese medicine fingerprint with the super information characteristics to give the 42 parameters such as chromatographic fingerprint index (F), chromatographic fingerprint resolution index (RF), which could thoroughly disclose the hidden information in the fingerprints. Meanwhile, the apparent molecular weight, the peak position, the elution fore index and the pseudo peak area were marked in terms of the principle of QSPR when the two peaks were selected as the reference peaks. RESULTS: 21 co-possessing peaks were selected as the fingerprint peaks of Ixeris sonchifolia Hance Injection by taking caffeic acid peak as the reference peak to establish the digitized fingerprint and obtain the important digital information about its quanlity control. The stabilities among different batches of samples were evaluated by the dual qualitative and dual quantitative similarity method. CONCLUSION: This new digitized fingerprint method with good precision and reproducibility can be perfectly applied to the quality control over Ixeris sonchifolia Hance Injection. Digitized fingerprint obtained from the dual qualitative and dual quantitative similarity method maybe extend further to assess and control the quanlity of TCM.
ABSTRACT
AIM: To establish a novel method for the overall quality control of Fructus Gardeniae by HPLC digitized fingerprint and its normalization. METHODS: The chromatographic fingerprints were obtained by injecting 5 ?L of the sample solution each time on a Century SIL C_ 18 BDS column (20 cm?4.6 mm, 5 ?m) with the gradient elution solvent system composed of 1% acetate acid-water and 1% acetate acid- acetonitrile.
