孕妇产前心理状态与需求的调查

目的对孕妇产前心理状态及其影响因素进行调查和评定,以探讨心理因素对分娩方式的影响。方法用综合医院焦虑/抑郁情绪测定量表,采用调查问卷法。结果有焦虑/抑郁症状组与无焦虑/抑郁症状组剖宫产率分别为80%和30%,差异有非常显著性(χ2=25.25,P<0.01);两组产后出血和新生儿阿氏评分,差异也有非常显著性,对婴儿的哺乳喂养方式(母乳、混合、人工)两组亦存在显著性差异(χ2=7.36,P<0.05)。结论产前对有焦虑/抑郁障碍的孕妇进行科学、整体的护理,实施有效的心理干预,可以减轻甚至消除焦虑/抑郁情绪,使孕妇处于最佳身心状态,保障母婴平安度过分娩期。     

上海市闵行区性病门诊本地和外来病人的比较研究

目的分析和比较上海市闵行区性病门诊本地与外来病人的流行病学特征。方法对2001~2004年上海市闵行区3家设有标准化性病门诊的公立医院进行门诊病历的回顾性分析。结果外来人口约占全部性病门诊病人的50%,其中女性病例占18.2%,未婚者占23.8%,均高于本地同类人员的比例;外来病人年龄偏低,多重感染者比例较高;男女外来病人与本地病人的首诊原因和症状排位相同,均以淋病感染为主;外来病人随访率(81.2%)较本地病人低(86.0%)。结论性病门诊本地和外来病人在人口学特征、诊疗行为上存在差异,防制措施应有所不同和侧重。

系统干预对老年痴呆患者激越行为的影响

目的探讨系统干预对老年痴呆患者激越行为的影响.方法将67例老年痴呆患者随机分为观察组(35例)和对照组(32例).对照组行常规药物治疗和康复训练,观察组在此基础上实施系统干预,连续3个月后应用激越问卷(CMAI)评价护理效果.结果干预前,两组CMAI评分差异无显著性意义(P>0.05);干预3个月后,两组CMAI评分均显著低于干预前(均P<0.05),但观察组激越行为改善程度显著优于对照组(P<0.05).结论系统干预能更为有效地缓解老年痴呆患者的激越行为,稳定病情,提高其生活质量.

Effect of the menstrual cycle and oral contraceptives on aromatase and cyclooxygenase-2 expression in adenomyosis.

OBJECTIVES: To determine whether aromatase expression in the eutopic endometrium and adenomyotic foci is affected by previous use of oral contraceptives containing gestodene, and to determine whether changes in cyclooxygenase-2 (COX-2) expression occur in adenomyosis during the menstrual cycle. PATIENT AND METHODS: This was a retrospective cohort study carried out in paraffin-embedded endometrial tissue obtained from patients with a histological diagnosis of adenomyosis obtained during the proliferative (n = 25) and luteal (n = 10) phases of the menstrual cycle and following the use of continuous oral contraception with gestodene/ethinyl estradiol (n = 7). COX-2 and aromatase expression were measured in both eutopic endometrium and adenomyotic foci using immunohistochemical methods. RESULTS: Aromatase expression was detected in 80% of the endometrial slices by immunohistochemistry. In positive cases, aromatase was mainly detected in the stromal cells of the eutopic endometrium, whereas in the adenomyotic foci this expression was negative in the majority of the cases. Oral contraceptives containing gestodene, on the other hand, were effective in suppressing aromatase expression in both eutopic and ectopic endometrium. COX-2 expression was detected by immunohistochemistry in the glandular epithelium of both eutopic endometrium and adenomyotic foci and there were no significant changes in its intensity throughout the menstrual cycle. CONCLUSION: Aromatase expression in the eutopic endometrium and adenomyotic foci is suppressed by oral contraceptives containing gestodene. Increased aromatase activity may be responsible for the persistent COX-2 expression during the luteal phase.     

太阳病"汗法"初探

仲景所著《伤寒论》冠古绝今,书中398条原文,太阳病篇所占178条,足以突出太阳病篇在六经辨证中的重要性.众所周知,太阳病的基本病机是感受风寒,营卫失调;其基本治则为辛温解表;“汗法”在治疗中占有极其重要的地位.用之正确则药到病除,用之不当则变证从生.仲景在太阳病篇中对“汗法”有很详细的描述,初探如下.     

Left pulmonary artery evaluation through transesophageal echocardiography.

INTRODUCTION: Transesophageal echocardiography (TEE) has become increasingly useful in the study of patients with suspected pulmonary thromboembolism. OBJECTIVE: The aim of this study was to prospectively evaluate the usefulness of TEE in the study of the distal part of the left pulmonary artery (LPA) as well as the influence of this procedure on total echocardiographic exam duration. METHODOLOGY: A prospective study in two groups of consecutive patients referred for TEE with a one- year interval between evaluation of Group A: 33 patients, 17 male, mean age 54 +/- 24 years, and Group B: 42 patients, 20 male, mean age 48 +/- 27 years (p = NS). The procedure was considered long when it took more than 3 min to evaluate the distal part of the LPA. RESULTS: In group A we were able to visualize the distal part of the LPA in 24 patients (73%) without significant prolongation of total exam duration in 16 patients (48% of group A). In one of the patients with suspected pulmonary thromboembolism thrombi were only observed in the distal part of the LPA. In group B we were able to visualize the distal part of the LPA in 36 patients (86%) without significant prolongation of total exam duration in 26 patients (61% of group B). CONCLUSIONS: 1. Visualization of the distal part of the LPA was possible in more patients, and with TEE time prolongation in less patients, in group B. These differences can be accounted for by the training of the operator in this technique. 2. The importance of visualization of this part of the LPA in guiding treatment in the subset of patients with pulmonary thromboembolism confirms the usefulness of this specific procedure.
