【摘要】 目的 了解甲型H1N1流感发热病区门诊就诊高峰期患者焦虑状况及相关因素，采取针对性护理措施减轻患者焦虑情绪。 方法 2009年11月上旬-12月上旬采用一般资料调查和Zung′s焦虑自评量表（SAS）对219例患者进行调查分析。 结果 219例患者SAS平均分为（33.70±8.60）分，其中17例SAS总分≥50分，存在焦虑情绪，发生率7.76%。多元回归分析结果显示，在年龄、性别、城乡差异、发热程度等因素中，与焦虑症状有关的主要因素为年龄和发热程度。 结论 甲型H1N1流感发热病区门诊就诊高峰期患者焦虑情绪明显高于常模，应引起重视，在门诊工作中加强心理护理，减轻和尽力消除患者的焦虑情绪，以免对病情产生不利影响，不利于控制流感疫情。【Abstract】 Objective To investigate the anxiety status and related factors of H1N1 patients at influenza peak of fever clinics,and to take specific measures to reduce anxiety in patients. Methods The general information and Zung′s self rating anxiety scale (SAS) were taken to analyze 219 patients from early November to early December 2009. Results The average SAS score of the 219 patients was 33.70±8.60, in which there were 17 patients (7.76%) with total scores ≥ 50 and anxiety. Multiple regression analysis showed that the age and temperature were related factors among age, gender, urban-rural differences, and fever. Conclusion The survey suggests that the pafients at the H1N1 influenza peak of fever clinics are significantly more anxious than normal anxiety. Out-patient work should strengthen psychological care to reduce and try to eliminate the anxiety of patients, in order to avoid adverse impact which is not conducive to control influenza outbreaks.
The incidence of prostate cancer ranks the second in malignant tumors among elderly males. Multi-parametric MRI (Mp-MRI) is an important mean for detection, staging, and grading of prostate cancer. In order to standardize the collection, interpretation, and reporting of prostate MRI data, the European Urogenital Radiology Society launched the Prostate Imaging Reporting and Data System (PI-RADS) in 2012. Due to some limitations in the application process, the Joint Committee of the American Society of Radiology and the European Society of Radiology issued an updated version of PI-PADS V2 in 2014. In recent years, some studies have been carried out on the effectiveness, accuracy, and consistency of the diagnosis of prostate cancer. This article will review the application and research status of PI-RADS V2 system in the diagnosis of Mp-MRI for prostate cancer.
目的 探讨3D-多体素磁共振波谱（MRS）在评估脑胶质瘤手术切除程度的价值。 方法 对2011年6月－2012年4月32例脑胶质瘤患者术后行常规MRI及MRS检查，测定分析手术周边区域主要代谢产物N-乙酰天门冬氨酸（NAA）、胆碱（Cho）、肌酸（Cr）、Cho/NAA、Cho/Cr及NAA/Cr比值，对术后胶质瘤切除程度进行评价。同时通过术后病理检查结果评估肿瘤切除程度，再与MRS评估结果相比较。 结果 32例中病理评估为9例全切除，23例为大部分切除；MRS评估为11例全切除，21例为大部分切除，评估结果与术后病理评估结果差异无统计学意义（P＞0.05）。 结论 MRS可以无创评价胶质瘤切除程度，为胶质瘤预后判定及进一步治疗提供了重要的依据。
Objective To investigate the application of the dynamic contrast enhanced MRI (DCE-MRI ) combined with magnetic resonance spectroscopy (MRS) in the diagnosis of prostate cancer. Method A total of 60 patients with prostate cancer and 60 patients with benign prostatic hyperplasia diagnoses in Sichuan Cancer Hospital from January 2011 to January 2014 were included as prostate cancer group and proliferative group respectively. Sixty healthy individuals during the same period were included as the control group. We used Siemens Avanto 1.5 T high field superconducting MRI for DCE-MRI scan and MRS scan. After the MRS scan was finished, we used the workstation spectroscopy tab spectral analysis. Eventually we got the crest lines of prostate metabolites choline (Cho), creatine (Cr) and citrate (Cit). Then we calculated Cho/Cit, (Cho+Cr)/Cit and their average. Results Comparing the signal value in 21 seconds, 1 minute, 2 minutes of DCE-MRI, the differences among the three groups were statistically significant (P<0.05). Comparing the results of spectral analysis, the differences among the three groups were statistically significant (P<0.05). The sensitivity was 89.67%, the specificity was 95.45% and the accuracy was 94.34% when using DCE-MRI combined with MRS. Conclusion DCE-MRI combined with MRS greatly improves the sensitivity, specificity and accuracy of the diagnosis of prostate cancer; it has a great application value in the diagnosis of prostate cancer.
ObjectiveTo explore the value of gadobutrol enhanced magnetic resonance angiography (MRA) in abdominal artery angiography.MethodsThe patients were prospectively included for gadobutrol enhanced MRA examination from December 2014 to December 2015. The image quality was assessed by two radiologists. The subjective score and signal intensity were measured for the large and medium arteries, and the subjective score for the small artery was recorded. The Kappa consistency analysis was used to assess the two radiologists’ subjective score.ResultsAll 112 patients were enrolled in this study, 96 of whom were included for the physical examination, 16 of whom were included for the liver tumors. No adverse reactions were found in these patients. The MRA images of 2 patients were affected by the severe respiratory artifact. The MRA images of the other 110 cases were clear and could well show the origins, shapes of large and medium arteries and small arteries. The subjective scores were 21.22±1.93 and 6.24±1.33 of the large and medium arteries and small arteries, respectively. The values of signal noise ratio and contrast signal noise ratio of the large and medium arteries were 1 093.27±331.71 and 897.27±333.29, respectively. The Kappa values of the two radiologists’ subjective score were 0.782 and 0.772 for the large and medium arteries and small arteries, respectively.ConclusionsGadobutrol enhanced MRA can clearly display large and medium arteries, and can also display some small arteries. It has a good application value in abdominal artery angiography.
