  • Bibliometrics on Electronic Health Records of Web of Science

    Objective To investigate the current status and development of electronic health records (EHR) at home and abroad to grasp the development trends of EHR, so as to point out the direction of the development and relevant research on EHR. Methods Based on the Web of Science citation database and the principle of bibliometrics, we analyzed the retrieved literature in aspects of publication date, language, country/region, institution, author, etc. Results A total of 1 262 eligible studies were identified. The number of articles on EHR increased rapidly from only 2 in 1995 to 218 in 2012. In terms of country/region, the United States ranked the top in all countries (763 articles, accounting for 60.46%). In terms of institution, Harvard University ranked the top (135 articles, accounting for 10.70%). In terms of journal, the Journal of the American Medical Informatics Association ranked the top (106 articles, accounting for 8.40%). In terms of authors, David W. Bates ranked the top (45 articles, accounting for 3.57%). In terms of subject type, health care sciences services and medical informatics were mainly focused on. Conclusion The research on EHR has become a global hot spot and relevant bibliometrics will contribute to the timely and correctly grasp the whole picture of its development trends and main research direction.

  • Optimization of Electron Paramagnetic Resonance Spectrum Fitting Procedures in Radiation Dose Reconstruction Using Enamel

    【摘要】 目的 优化牙釉质电子顺磁共振(EPR)谱拟合程序。 方法 将牙釉质EPR谱拟合程序中的RIS-BGS偏移量设置为定参,取优化值;增加手动拟合功能,可以将参数初始值直接代入高斯模型得到拟合谱。 结果 将牙釉质EPR谱拟合程序中RIS-BGS偏移量设置为定参后,其优化值为0.529,减少了变参数量;采用手动拟合功能有助于调整参数初始值;在自动拟合程序对于个别样品谱不能给出正确结果情况时,仍然可以通过手动拟合来得到一个近似的拟合结果。 结论 优化了EPR谱拟合程序的应用过程。【Abstract】 Objective To optimize the enamel electron paramagnetic resonance (EPR) spectrum fitting procedure. Methods RIS-BGS offset was set as a determined parameter in enamel EPR spectrum fitting program, and an optimized value was given for RIS-BGS offset. A manual fitting function was designed that can substite the initutial value into the Gaussian model function directly. Results RIS-BGS offset was set as a determined parameter, the optimized value of which was 0.529. The number of parameters decreased; the manual fitting function maked it easier to select initial values for parameters. When the auto fitting program failed to give a correct result for some EPR spectrum, a fitting result could still be obtained with the manual fitting method. Conclusion The application of the spectrum fitting procedure can be optimized.

  • Applications of 18F-Fluorodexyglucose Positron Emission Tomography on the Diagnosis and Treatment of Carcinoma of Large Intestine

    Objective To introduce the current study on 18F-fluorodexyglucose positron emission tomography (18F-FDG PET) scanning in diagnosis and treatment of carcinoma of large intestine. Methods The literatures about 18F-FDG PET scanning in diagnosis and treatment of carcinoma of large intestine in recent years were reviewed. Results 18F-FDG PET scanning is superior to CT and MRI in identificating carcinoma of large intestine recurrence, metastasis in the early stage after operation and staging carcinoma of large intestine. Conclusion 18F-FDG PET scanning may be one of the accessory examinations in carcinoma of large intestine and may be helpful for the choice of treatment.

  • The CT Features of Gastric Bare Area under Pathological Conditions

    ObjectiveTo investigate the CT presenting rate and features of gastric bare area (GBA, including the area posterior to GBA and the adipose tissue in the gastrophrenic ligament) without pathologic changes.MethodsThirty cases with superior peritoneal ascites, but without pathological involvement of GBA were included into the study to show the normal condition of GBA, including the presenting rate and CT features. We selected some cases with GBA invasion by inflammation or neoplasm to observe their CT features. ResultsAll cases with superior peritoneal ascites showed the GBA against the contrast of ascites with the presenting rate of 100%. The GBA appeared at the level of gastricesophageal conjunction and completely disappeared at the level of hepatoduodenal ligament and Winslow’s foramen. The maximum scope of GBA presented at the level of the sagital part of the left portal vein with mean right to left distance of (4.39±0.08)cm (3.8~5.7 cm) (distance between the left and right layer of the gastrophrenic ligament). In acute pancreatitis, the width of GBA increased, in which local hypodensity area could be seen. In gastric leiomyosarcoma invading GBA, the mass could not separate from the crus of the diaphragm. In lymphoma and metastasis invading GBA, the thickness of GBA increased and the density was heterogeneous, in which lymph nodes presenting as small nodes or fused mass. ConclusionThe results of this study show that it is helpful to use contrast enhanced spiral CT scanning to observe the change of GBA and to diagnose retroperitoneal abnormalities that involving GBA comprehensively and accurately.

    Objective To explore the imaging features of acute exacerbation of idiopathic pulmonary fibrosis ( IPF) under high-resolution computed tomography ( HRCT) . Methods The HRCT imaging features of six patients who met the criteria for acute exacerbation of IPF were analyzed retrospectively. Results The manifestations of IPF on HRCT scan were various in forms and distribution, as multifocal, ground-glass opacity, reticular shadow, honeycombing densities, capillary bronchiectasis,subpleural lines, traction bronchiolectasis and emphysema. The characteristic lesions were newly diffuse bilateral ground-glass opacity at the time of acute exacerbation, superimposed on subpleural reticular and honeycombing densities. Conclusions Chest HRCT findings in acute exacerbation of IPF are characteristic.HRCT is accurate and superior in diagnosis of IPF and in determining acute exacerbation of IPF.

  • Diagnosis and Therapy of Patients with Descending Necrotizing Mediastinitis

    Abstract: Objective To explore the diagnosis and treatment of descending necrotizing mediastinitis (DNM). Methods We retrospectively analyzed the records of eight DNM patients treated at Tangdu Hospital between 2006 and 2009 year. There were 7 males and 1 female aged from 21-98 years with a median age of 49.5 years. The diagnostic criteria included clinical manifestations, neck and chest CT scans, and bacteriological culture. Six of the patients had odontogenic infections and six had diabetes. Antibiotic treatment, incision drainage, and other symptomatic treatments were applied. Two patients received cervical incision drainage, five received thoracotomy, and one received video-assisted thoracoscopic surgery (VATS). Results After treatment, six patients recovered and two died of heart failure and neck vessel rupture. According to the bacterial culture, six patients presented mixed infections, and four of these presented mixed aerobic and anaerobic infections. The mean operation time was 75.6 minutes, the average volume of pus removed during the operation was 318.7 ml, and the average inpatient stay was 18 days. At six months follow-up, all six surviving patients showed improvements in quality of life. Conclusion The valid diagnosed criteria of DNM include history, sign, symptom, neck and chest CT scanning, and secretion culture.DNM mortality can be reduced by employing broad spectrum antibiotics early in treatment, individual surgical managements, and effective treatments for complicating illnesses.
