心脏磁共振诊断非缺血性心肌纤维化中的应用进展

心脏磁共振使非缺血性心肌纤维化的无创诊断和预后评价成为了可能。目前的半定量延迟强化显像,影响因素较多,在弥漫性心肌纤维化中很难形成对比,得到可靠信息。T1mapping是一种新型的可定量评估心肌特征的方法,对局部及弥漫性心肌病变,心肌细胞外间质扩大及水肿方面有着良好的应用前景,助于对弥漫性病变进行早期诊断和治疗。     

低张双对比造影对胃癌前病变的诊断价值

目的探讨低张双对比造影对胃癌前病变的诊断及病变的影像特征。方法应用低张药物行胃双对比造影,辅以幽门螺旋杆菌（helicobacter pylori HP）^13C尿素呼气试验;选取45例疑有胃癌前病变患者再行胃镜及镜下取样病理活检;并将造影所见与胃镜及病理结果比较分析。结果（1）造影结果与胃镜及病理结果大部分相符,经证实41例（符合率约91％）。（2）其主要的X线表现为病变区胃小区的不规则增大、隆起、变形,胃小沟增宽、宽窄不均和粘膜下结节样增生,胃舒张性减低等征象。结论（1）清晰显示胃小区的改变是诊断的关键。（2）辅以HP检测能明显提高诊断率。（3）胃癌前病变的X线表现有一定的特征性,良好的双对比造影可对大多数病变作出初步诊断。

Reliability of the Japanese version of the Inventory to Diagnose Depression

Abstract The reliability of the Japanese version of the Inventory to Diagnose Depression (IDD) which is a self-report to diagnose major depressive disorders (MDD) of DSM-III-R, was investigated in 30 cases with MDD and 30 control subjects. On test-retest reliability, the agreement of diagnostic performance was substantial ( K = 0.64, P < 0.001) for 60 subjects, and scores of total and individual items correlated significantly ( P < 0.001) between test and retest except for decreased energy, decreased interest, and decreased concentration. The average score of the total IDD severity at test (38.4) was significantly higher than that at retest (28.0; P < 0.01). However, excluding the recovered 10 cases, there was no significant difference seen on the average total score between test and retest (38.8, 30.1, respectively). Internal consistency (Cronbach's a = 0.80) and split-half reliability (0.79) were sufficient, and item-total correlations of the IDD were significant ( P < 0.01) except for weight gain. The IDD might be useful as a screening tool and for clinical evaluation of subjects in Japan; however, it is necessary to examine the validity of this instrument.     

肺功能评价软件系统

本系统具有以下功能:(一)根据我国主要的几个地区的正常人的参考值预计方程式来计算当地患者的正常参考值及其95％可信限和实测值占参考值的百分比,按美国胸腔学会标准,用计算机代替人来对患者的肺功能异常与否及损害程度进行评价。(二)对要做胸腹手术的病人可根据其通气功能来估计术后出现肺部合并症的机会高低,以提请医生注意。(三)因为有时肺功能的评价要结合临床在不典型或边缘状态,医生可用本系统自己做补充说明及打印报告单。     

Trouble in the office: liability issues in ambulatory care

Most clinicians are keenly aware of the liability risks associated with adverse birth outcomes for mother and/or infant. This level of awareness and concern also needs to extend to the day-to-day management of office practice. Clinicians who care for healthy women and their families may see abnormalities infrequently. The low yield of abnormal results means that close monitoring is essential to prevent overlooking the rare abnormal finding. This article focuses on three areas of liability risk for midwives and others who practice in the ambulatory setting: 1) inadequate tracking of test and referral results, 2) failure to diagnose, and 3) poor communication. Although none of these issues are limited to the ambulatory setting, only office practice is addressed in this article.

Root ZX根尖定位仪诊断牙根横折的实验研究

目的研究Root ZX根尖定位仪是否能准确诊断牙根横折的存在。方法将20颗离体单根管上前牙形成牙根横折,用Root ZX根尖定位仪分别测量横折断端不分离、横折断端分离但断端内无印模材料、横折断端分离且断端内有印模材料3种情况下的根管长度,并与实际根管长度进行比较。结果在横折断端不分离、横折断端分离但断端内无印模材料2种情况下,根尖定位仪不能探测到横折位置;在横折断端分离且断端内有印模材料情况下,电测根管长度在横折冠段实际根管长度±0.5 mm范围内为100%,可探测到横折位置。结论Root ZX根尖定位仪对没有软组织长入的牙根横折无诊断价值,但对有软组织长入的牙根横折有很好的准确性。
