Objective: To further optimize the hospital inspection process, shorten the patient waiting time of examination and improve the overall utilization of medical equipment. Methods:HIS and PACS to realize the information system integration by using hospital information platform, and then develop a set of medical equipment reservation system. The doctor workstation through the system could real-time help patient appoint check items, and eliminate patients to check the front desk or reservation center reservation registration steps. Results:The successful application of medical equipment reservation system not only optimize hospital inspection process, shorten the patient waiting in line inspection time, but also increase the utilization rate of MR equipment by 35%. Conclusion: The use of medical equipment reservation system saves the patient queuing registration, waiting for the examination of the time, and improve the utilization rate of hospital medical equipment, create economic benefits for the hospital and brought widespread popularity and reputation for the hospital.

OBJECTIVE:To optimize the ultrasonic-assisted extraction technology of total flavonoids from Tibetan Scindapsus aureu. METHODS:The single-factor test was adopted to investigate the effects of extraction time,extraction temperature,the vol-ume fraction of ethanol,the ratio of liquid to solid and power on the extraction rate of total flavonoids from Tibetan Scindapsus au-reu in the process of ultrasonic-assisted extraction,based on which,four-factor and five-level Box-Behnken central component de-sign was performed with unchanged ultrasonic power,and then response surface method was adopted to analyze the effects of the 4 factors and their interaction on the extraction rate of total flavonoids to determine the optimal factor and level,and verification tests were conducted.RESULTS:The optimal ultrasonic-assisted extraction technology was as follows as extraction time of 29 min,tem-perature of 44 ℃,volume fraction of ethanol of 78%,ratio of liquid to solid of 13∶1(ml/g). In three verification tests,the aver-age extraction rate of total flavonoids was 2.130%,with an relative error of 0.005% compared to the theoretical value. CONCLU-SIONS:The optimal technology is reasonable and feasible,and can be used for theultrasonic-assisted extraction of total flavonoids from Tibetan Scindapsus aureu.

Command of the JCI standards and lessons learnt from practice and experience in JCI accreditation preparation,can help identify the gap between the hospitals and JCI standards.These standards can also guide the clinical pathway system,pharmacy intravenous admixture services system and medical business intelligence system.The information system built under such guidance not only makes an effective solution to existing problems,but also proves innovative.All these pave the way for successful JCI accreditation.

It has been confirmed that hepatocellular carcinoma belongs to gene related disease.Biological characteristic of hepatocyte can be infected by abnormal expression of related genes,resulting in normal cell transformed to carcinoma cell,therefore,we should do further research to find new methods for diagnosis and treatment of HCC.As a new technique for gene knockdown,RNAi has been applied more in the fields of gene function and gene therapy.This paper is a review about recent advance in HCC gene therapy with RNAi.

Alpha-fetoprotein is an important molecular marker for clinical diagnosis, evaluation of curative effect and prognosis of cancer for long time, especially for hepatocellular carcinoma. But for physiological function of alpha-fetoprotein, we know less than its clinical significance. So here this article presents a review about physiological function of alpha-fetoprotein and its application in molecular therapy of hepatocellular carcinoma.

砄bjective: To study the effects of functinal appliances combined with activator headgear in the treatment of Class II division 1 malocclusion with or without high mandibular angle. Methods: 5 cases (10～12 years old) of class Ⅱ division 1 malocclusion with high mandibular angle (FMA≥34?,HMA) and 8 cases (9～12 years old) without the high angle (FMA

Objective To review the pathogenesis of osteoarthritis ( OA) and microsphere delivery systems advances in the field of osteoarthritis treatment, and provide theoretical support for clinical research and osteoarthritis therapy.Methods The literatures on osteoarthritis have been reviewed in recent years, and pathogenesis and osteoarthritis therapy were summarized.ResuIts At present, the therapy of OA was gradually from symptoms relief to pathogenesis, and further revealed the inner regularity of osteoarthritis treatment.However, a variety of western medicines had its own limitations. ConcIusion In recent years, intra-articular injection therapy because of its unique advantages in clinical treatments,attracts widespread attention, and particularly the microsphere injection with superior prospects is researched more in the field of new formulations.

Objective:To study the structural changes of upper airway i n the patients with Angle Ⅱ 1 malocclusion treated by orthodontic appliance. Methods:12 patients with Angle Ⅱ 1 malocclusion caused by mout h breathing were treated by rapid maxillary expansion (RME) of splint and Tip-E dge technology, the structure of upper airway was measured before and after trea tment,the data were analyzed. Results:After treatment PNS-Ba,SP P-SPPW,P-T,TB-TPPW,V-LPW,UC-LC and H-C3(hor) increased(P

Objective To evaluate the curative effect and indications of medical ozone for the treatment of lumbar disc herniation.Methods 10~20 ml(35~45 ug/ml) medical ozone was injected into the lumbar disc percutaneously each case. The patients were followed up for 6~12 months. Results 60 cases (66 lumbar discs) with lumbar disc herniation were treated with the injection of medical ozone. The total effective rate was 96.67% , excellent and good rate was 76%.The efficacy in herniation to be 30% of vertebral canal diameter and lumbardisc bulging group. Conclusion The treatment of lumbar disc herniation with medical ozone is simple,effective and no complications.

[Objective]To research the efficient way of isolating and proliferating of induced endothelial cells(ECs) ,measure the number of the ECs and observe the main biological characteristic of ECs m vitro during the passage cultivation.[Method]The marrow mononuclear cells(MNCs) in rabbit marrow were isolated by the gradiem centrifugation and cultivated to isolate and induce ECs. The efficiency of isolating and harvesting ECs was measured by the number of the first passage ECs from every 10~6 of the MNCs. The changes of ECs morphology, growth and proliferation were observed during the passage cultivation. The immunohistochemical staining of CD31 and vWF and function of ECs were checked.[Result]After cultivated at 1?10~6/cm~2 MNCs for 7～8 d, the first passage ECs were harvested. The number of the first and the second passage ECs had a remarkable statistical positive correlation with the number of the MNCs from one rabbit. After cultivated for 7～8 d, the first passage ECs of 7.086?0.75?10~4 in number and the second passage ECs of 53.20?6.47?10~4 in number were harvested from every 10~6 MNCs on average;ECs, which were monolayer arrayed to form cobblelike shape,The cells of 2nd passage showed positive staining of CD31 and vWF, and positive labeling of DiI-LDL and UEA.[Conclusion]The period from cultivating to harvesting ECs is shortened at the density of 1?10~6/cm~2 MNCs. It is feasible that the efficiency of isolating and harvesting ECs could be measured by the number of the first or the second passage ECs from every 10~6 MNCs. The induced ECs can act as seeding cells in bone tissue engineering in future.
