清开灵注射液治疗脑血管性痴呆32例

目的观察清开灵注射液治疗脑血管性痴呆的疗效.方法将中医学辨证属于实证的64例脑血管性痴呆患者随机分为治疗组(清开灵注射液组)和对照组(脑复康组),治疗5周后,将两组治疗前后在智力障碍程度、肢体功能、血液流变学指标、中医证型疗效方面的变化进行比较.结果经治疗后治疗组和对照组相比较,智力障碍程度变化(有效率、MMSE、ADL积分)、肌力、步行能力改变有显著性差异,p＜0.05.而治疗前后组内及组间血流变指标虽有一定下降,但无统计学意义(p＞0.05).结论清开灵注射液对脑血管性痴呆患者,在改善智力障碍、肌力、步行能力方面有较好的疗效.     

236例无痛人工流产术的疗效观察

目的:探讨异丙酚和芬太尼混合液静脉麻醉、笑气吸入麻醉及2%利多卡因宫颈局部浸润麻醉三种镇痛方法在人工流产手术中的疗效比较。方法:自2003年8月至2004年1月对236例妇科门诊早孕要求终止妊娠的妇女实施无痛人工流产术。随机分成3组。A组:异丙酚+芬太尼静脉麻醉(85例);B组:N2O(笑气)吸入麻醉(88例);C组:2%利多卡因宫颈局部浸润麻醉(63例),观察人流术中其镇痛效果并对疼痛进行分级。结果:A组85例100%可达到完全不痛(疼痛分级为0级);B组65.90%可达到完全不痛,Ⅰ级23.86%,Ⅱ级9.09%,Ⅲ级1.15%;C组0例可达到完全不痛,Ⅰ级63.49%,Ⅱ级30.16%,Ⅲ级6.35%。结论:受术者如无心肺疾患及人流禁忌证,无痛人工流产术应选择异丙酚+芬太尼静脉麻醉可达到完全无痛,痛苦最小。

头颈部肿瘤CT灌注成像表现与微血管生成因子表达水平的相关性研究

目的研究头颈部肿瘤CT灌注与肿瘤血管生成因子（VEGF）的相关性。方法对85例共88个（恶性77个，良性11个）头颈部肿瘤术前行CT灌注检查。采用螺旋CT机自带软件绘制感兴趣区（ROI）的时间-密度曲线（TDC）并计算ROI强化峰值（PH）、达峰时间（PT）、平均通过时间（MTT），病灶相对强化峰值（RPH）和灌注量（PF）。其中35例切取与CT灌注靶层面相同的组织切片，行CD34、VEGF抗体免疫组织化学染色，分析肿瘤CT灌注成像表现与微血管密度（MVD）和VEGF表达的相关性。结果（1）头颈部肿瘤CT灌注成像TDC主要有3种类型，77个恶性肿瘤中53个（68．9％）表现为速升速降型；9个淋巴瘤中6个TDC表现为低平型曲线，与68个其他肿瘤中仅有9个为低平型曲线相比差异有统计学意义（P〈0．05）。（2）甲状腺癌呈高灌注，其PF（中位数为82．2ml·min^-1·100g^-1）与淋巴瘤PF（中位数为24．5ml·min^-1·100g^-1）、头颈鳞癌PF（中位数为23．8ml·min^-1·100g^-1）相比差异有统计学意义（P〈0．05）。（3）11个良性肿瘤的MVD均数为（44．7±3．4）条／高倍视野，24个恶性肿瘤的MVD为（49．6±14．8）条／高倍视野，良恶性肿瘤间差异无统计学意义（P〉0．05）；VEGF在恶性肿瘤呈强阳性者15个，弱阳性9个；在良性肿瘤呈强阳性1个，弱阳性10个，VEGF的表达强阳性率在良、恶性肿瘤差异有统计学意义（P〈0．01）。（4）MVD（中位数40．0）与PH（中位数26．9）、RPH（中位数14．5）和PF（中位数46．8）有明显相关性（r值分别为0．35、45．49和0．41），VEGF（中位数4．0）表达与MTT（中位数16．7）呈负相关（r=-0．41）。结论CT灌注成像TDC形态对头颈部肿瘤诊断及鉴别诊断有一定的帮助。MVD、VEGF与CT灌注相关，CT灌注成像可以反映肿瘤微循环情况。     

Assessment of quality of life in children with peanut allergy

Children with a peanut allergy (PA) are faced with food and social restrictions due to the potentially life-threatening nature of their disease, for which there is no cure or treatment. This inevitably impacts upon their quality of life (QoL). QoL of 20 children with PA and 20 children with insulin-dependent diabetes mellitus (IDDM) was measured using two disease-specific QoL questionnaires (higher scores correspond to a poorer QoL). One questionnaire was designed by us and the other was adapted from the Vespid Allergy QoL questionnaire. We gave subjects cameras to record how their QoL is affected over a 24-h period. Response rates for both questionnaires were 100%. Mean ages were 9.0 and 10.4 years for PA and IDDM subjects, respectively. Children with a PA reported a poorer quality of life than children with IDDM: mean scores were 54.85 for PA subjects and 46.40 for diabetics (p = 0.004) in questionnaire 1 and 54.30 and 34.50 (p≤0.001) in questionnaire 2. PA children reported more fear of an adverse event and more anxiety about eating, especially when eating away from home. Photographs fell into seven common categories: food, management, environment, away from home, physical activities, restaurant and people. Most photographs related to food and management issues and revealed difficulties for both groups regarding food restrictions. PA subjects felt more threatened by potential hazards within their environment, felt more restricted by their PA regarding physical activities, and worried more about being away from home. However, they felt safe when carrying epinephrine kits and were positive about eating at familiar restaurants. The QoL in children with PA is more impaired than in children with IDDM. Their anxiety may be considered useful in some situations, promoting better adherence to allergen avoidance advice and rescue plans.     

复方角菜酸酯栓在痔上黏膜环形切除钉合术后的临床应用评价

目的评价复方角菜酸酯栓对缓解痔上黏膜环形切除钉合术(PPH)后患者早期不适症状方面的疗效。方法选取2002年11月至2003年7月行PPH的80例患者,随机分为治疗组(复方角菜酸酯栓组,42例)和对照组(常规处理组,38例),分别记录两组患者术后24h和第6及第12天时的症状改善情况、术后24h有无尿潴留情况、术后首次排便时间、试验结束时伤口愈合情况、住院时间和换药次数、停药及停药的原因以及伴随用药情况。结果术后24h治疗组患者症状总得分(4.4)较对照组(6.1)低,P<0.05。但至术后第6和第12天时,两组症状得分比较,差异无统计学意义(P>0.05)。治疗组患者在各时间点的症状得分减少值均高于对照组(P<0.05)。两组患者在术后24h出现尿潴留的比率和住院天数方面比较,差异无统计学意义(P>0.05)。结论复方角菜酸酯栓对于缓解PPH术后早期的不适症状效果良好。     

TEN YEARS' EXPERIENCE IN LOW VISION PRACTICE

The Low Vision Clinic at the Palmerston North Hospital has now been oerating for 70 years. Over the course of these ten years a number of factors have emerged which can be as readily applied to general ophthalmological practice as to low vision practice. The philosophy of low vision care is one of which all ophthalmologists should be aware and includes factors to be taken into account when dealing with children, people in the workplace, and everyday factors involved in daily living activities, all of which are equally relevant in routine ophthalmological practice. This paper endeavours to share some thoughts on these factors and also discusses means by which the visually handicapped can be helped in areas where specialist low vision services are not readily available.
