暗纹节菱孢所致皮肤真菌病组织病理学及超微结构观察

本文报告了暗纹节菱孢[Arthinium phaeospemum（Corda）Ellis]所致皮肤真菌病的组织病理学及超微结构观察。HE、PAS、镀银染色（Szatri）法及铅铀染色，对皮损的组织病理改变，进行了光镜及透射电镜观察。光镜下发现暗纹节菱孢引起真皮及皮下脂肪组织广泛性病理浸润，由多种细胞构成的肉芽肿，尤其对皮肤附属器严重破坏。在病理浸润中可见球形、卵圆形、菱形及晶体形，玫瑰红色、棕色及褐色孢子。透射电镜下见真皮成纤维细胞胞浆内吞噬多数界线清楚的圆形小体，空泡内也有相同的小体，胞浆空泡甚多，胞核完整。同时见到破坏的溶酶体。病理浸润内形态各异的孢子及不同颜色，是孢子生长的不同阶段。     

Efficacy and safety of herbal medicines for idiopathic Parkinson's disease: a systematic review.

The objective of this study is to assess the efficacy and safety of herbal medicines (HMs), as a monotherapy or adjunct therapy, compared to placebo or conventional approaches in the treatment of idiopathic Parkinson's disease (PD). We conducted a systematic review of randomized controlled trials from both conventional and alternative medicine sources. Outcome measures were overall improvement, quality of life, reduction of levodopa dose, and adverse events. Nine studies were included, each testing a different HM. Six of the trials had limited internal validity due to major flaws in design, including the lack of proper randomization; insufficient blinding; unclear inclusive criteria in terms of diagnostic criteria, baseline staging, and duration of disease; lack of proper sample size calculation; and insufficient data analysis. Imbalances in gender and ethnicity among the patients in the included trials were observed. No major adverse events emerged, and no specific pattern was detected from the trials describing such data. In addition to major methodological defects, heterogeneity in (1) HM tested, (2) control treatment, and (3) outcome measure hindered in-depth data analysis and synthesis. Current evidence is insufficient to evaluate the efficacy and safety of various HMs. Further studies with improved trial design and reporting, with assessment on cost-effectiveness, quality of life, and qualitative data are warranted.     

慢性阻塞性肺疾病及肺心病中医证型与左心功能及血气分析的关系

目的探讨慢性阻塞性肺疾病(COPD)及肺心病不同中医证型左心功能指标的变化及血气分析的关系。方法研究组60例,其中COPD患者33例,合并肺心病患者27例,所有患者根据中医辨证分型分为痰热壅肺证(20例)、痰湿蕴肺证(13例)、气阴两虚证(15例)和阳虚水泛证(12例);正常组15例来自本院体检正常者。研究组于入选当时按观察表详细记录患者症状、体征及舌脉情况,研究组和正常组均于48h内完成心功能检测和血气分析。比较研究组与正常组之间、研究组各证型之间心功能指标和血气分析的变化。结果(1)与正常组比较,研究组CI、ACI明显降低,STP、SVRI及TFC明显升高。(2)研究组各证型之间比较:气阴两虚与实证比较,CI明显降低,SVRI、TFC明显升高;阳虚水泛与实证比较,CI、LCWI明显降低,STR明显升高,SVRI、TFC明显升高;阳虚水泛与气阴两虚比较,只STR有明显差异。(3)各证型之间血气分析:阳虚水泛PaO2最低,其次为气阴两虚,阳虚水泛与实证比较差异明显。结论COPD及肺心病患者存在一定程度左心功能障碍,心功能指标可以作为评定COPD病情变化及证型演变的参考指标;显著的低氧血症是阳虚水泛证患者左心功能指标改变的重要原因。     

护理本科生创造性思维培训

[目的]对护理本科生实施创造性思维训练,并评估该训练方案的有效性。[方法]对20名护理本科生实施为期3个月的创造性思维培训,并与24名不接受培训者进行对照。采用《创造性思维练习》量表对培训前后学生的创造性思维进行测定。[结果]培训后实验组较对照组的创造性思维总分及流畅性得分有显著提高(P<0.05);变通性和独创性得分无统计学意义(P>0.05)。[结论]创造性思维培训对提高护理本科生创造性思维总体有效,其中对提高创造性思维的流畅性效果显著。     

92例重型肝炎并发自发性细菌性腹膜炎的诊断与治疗

目的探讨重型肝炎并发自发性细菌性腹膜炎(SBP)的诊断和抗生素使用。方法回顾性分析2002年7月~2005年6月间收治的92例并发SBP的重型肝炎患者的临床资料。结果92例患者中,发热72例(78.26%),腹胀85例(92.39%),腹痛38例(41.30%),反跳痛35例(38.04%),83例(90.21%)外周血中性粒细胞(PMN)分类≥0.75,40例(45.98%)腹水PMN计数≥250个/mm3,79例(90.80%)腹水PMN比值≥0.50,11例(12.00%)腹水细菌培养阳性,共分离出细菌17株,G-杆菌占52.9%(9/17),其对头孢曲松、头孢哌酮、头孢他啶、左旋氧氟沙星及泰能敏感,对丁胺卡那、氧哌嗪青霉素敏感性较低。临床治疗显示,联合使用头孢他啶和甲硝唑效果较好,并较少出现继发真菌感染。结论重型肝炎并发SBP患者的临床表现不典型,腹水培养阳性率低,外周血和腹水PMN比值是诊断SBP比较可靠的参数。治疗SBP,可首选二联使用头孢他啶与甲硝唑,疗程约10~14日。

慢性萎缩性胃炎是以胃黏膜上皮和腺体萎缩、黏膜变薄为特征的慢性疾病。属中医胃脘痛、胃痞等范畴。其病因病机较为复杂,多与饮食不调、情志不畅有关,尤其是饮酒、过食刺激之品,致使脾胃受损,阳气郁遏不振,纳运失司,化源不足,气血阴液亏乏;或中焦运化无力,湿邪滞塞,郁而化热;或     

Reproducibility of ultrasound pachymetry using the Sonogage Corneo-Gage Plus 2.

PURPOSE: The aim of this study was to determine the reproducibility of measurements made using the Sonogage Corneo-Gage Plus 2 (Cleveland, Ohio) ultrasound pachymeter of total corneal and corneal epithelial thickness in 5 different regions of the cornea. METHODS: Twenty-seven subjects at the New England College of Optometry (NECO) and 20 subjects at the Southern College of Optometry (SCO) were enrolled in this study. Measurements were taken of the central cornea as well as the nasal and temporal regions of the midperipheral and peripheral regions of the right cornea of each subject. Identical measurements were again taken in these subjects 1 week later at approximately the same time of day. Within-subject variations were then assessed using paired t tests. RESULTS: The only significant measurement differences that were found between visits were for full corneal thickness at both the nasal and temporal midperipheral locations. The mean differences for these locations were 13.5 microm and 13.7 microm, respectively. CONCLUSIONS: Epithelial corneal thickness and central and peripheral total corneal thickness measurements using the Corneo-Gage Plus 2 pachymeter were reproducible; however, midperipheral total corneal thickness measurements showed poor reproducibility.
