下腹部Joel—Cohen切口术后切口愈合临床观察

目的探讨肥胖患者下腹部手术采用Joel—Cohen切口对预防非感染性切口裂开的临床效果。方法选择切口部位皮下脂肪层厚达4—5cm的妇产科手术患者90例，随机分为观察组44例，采用Joel—Cohen切口；对照组46例，采用下腹正中直切口。观察切口愈合和脂肪液化情况。结果观察组切口甲级愈合率显著高于对照组（P〈0．01）；脂肪液化切口裂开率显著低于对照组（P〈0．05）。结论脂肪组织厚达4—5cm以上下腹部手术切口，采用Joel—Cohen切口可以减少脂肪液化，切口愈合显著优于下腹直切口，值得临床推广应用。     

NariSO3和NaCl联合增敏光度法测定碘盐中微量碘

研究亚硫酸氢钠和氯化钠配伍使用的增敏性,建立了NaHSO3—NaCl—KIO3—KI四元无机体系测定碘盐中碘含量的新方法。测定碘的最佳条件:磷酸介质,pH 3~4,最大吸收波长479 nm,ε479=1.5×105L/(mol/cm),碘含量(以KIO3中I计)在0~2.24mg/L内符合比尔定律。用于测定食盐中碘的含量,回收率为99.49%~101.3%,结果满意。     

铁叶绿酸钠对小鼠行为发育毒性的实验研究

铁叶绿酸钠为叶绿素衍生物,研究表明铁叶绿酸钠治疗妊娠期缺铁性贫血,疗效显著。由于妊娠期用药可能对子代产生行为发育毒性,因此本文重点针对铁叶绿酸钠在动物围产期用药后,可能对子代动物的神经行为发育产生的毒性进行了测试,试验结果表明在高、中、低三种剂量下其对子代小鼠无明显行为发育毒性。     

齿槽裂修复方法的研究进展

目的 探讨齿槽裂修复治疗的目的、方法以及治疗时机的选择。方法 查阅1950年至2006年有关齿槽裂修复的文献，归纳文献中报道的不同方法，并评价其各自的优缺点。结果 齿槽裂修复的主要目的：关闭口鼻瘘；建立稳定、连续的上颌骨牙弓；为牙齿萌出提供基础；为上唇和鼻底提供稳定支架。主要治疗方法：植骨术；牵引成骨技术；组织工程骨和生长因子应用；引导骨再生技术。患者最佳的手术治疗时机是9～11岁时混合牙列期。结论 在9～11岁混合牙列期手术，以髂骨松质骨为移植材料被认为是修复齿槽裂的主要手段。牵引成骨技术、组织工程技术和引导骨再生技术，将是齿槽裂修复的新方向。     

中西医结合治疗慢性鼻窦炎76例

目的观察中西医结合治疗慢性鼻窦炎的疗效．方法：对76例慢性鼻窦炎病人采用阿奇霉素，每次1粒（0．25g），替硝唑片每次1g口服，二者均一日1次，首剂量加倍，中成药藿胆丸每次服6克，一日两次，7天为一疗程，服药最长者2周。结果：显效56例（占73．7％），有效18例（占23．7％），无效2例（占2．6％），总有效率97．4％。结论：中西医结合治疗慢性鼻窦炎具有良好疗效。     

Collagenous colitis: Clinical and histological spectrum in ten patients

Collagenous colitis is characterized by the presence of a thick subepithelial collagen band in the colonic mucosa. The condition was diagnosed on rectal biopsy in 10 patients (one male, nine females) who presented with watery diarrhoea. Although rectal mucosal erythema was present in three and ulceration in two, the mucosa was of normal endoscopic appearance in five of the patients. There was marked variability in the thickness of the submucosal collagen band, both between and within individuals. Empirical drug therapy included sulphasalazine, glucocorticoids and antidiarrhoeals. All patients reported symptomatic improvement.     

产科危重患者多器官功能障碍综合征的临床分析

目的 :分析产科危重患者多器官功能障碍综合征 (MODS)的发病特点及诱因 ,以及与急性生理与慢性健康状况评分II(APACHEII)的关系。方法 :回顾分析 2 0 0 0年1月至 2 0 0 4年 4月转入GICU产科危重患者中发生MODS 6 6例的临床资料 ,并计算其A PACHEII评分。结果 :产科MODS患者诱因主要是产科因素 ,共 4 8例 (72 .73% ) ,死亡 7例 (14 .5 8% ) ,以重度子痫前期或子痫及产后出血为主 ;诱因 18例妊娠合并内外科疾病 ,死亡 11例 ,死亡率为 6 1.11% ,以妊娠合并心脏病和妊娠合并重症肝炎为主。产科MODS患者死亡率随着器官损害数的增多而上升 ,差异有显著性 (P <0 .0 5 ) ;随着器官损害数的增多 ,APACHEII评分逐渐升高 ,差异有显著性 (P <0 .0 5 ) ;APACHEII评分用于预测MODS死亡阳性率 ,2 ,3,4 ,5个器官受损害 ,其阳性率分别为 33.4 5 % ,5 7.12 % ,97.0 9% ,10 0 %。结论 :产科多器官功能障碍 /衰竭的产科主要诱因是重度子痫前期 /子痫 ,产后出血 ;产科MODS患者死亡率也随着器官损害数的增多而上升 ;APACHEII评分可在一定程度上作为评定产科MODS患者病情危重程度和预测预后的指标。     

Counterfactual (‘if only’) thinking in women with chronic widespread pain

The study explored the counterfactual thinking that women with chronic and widespread pain showed in response to what they themselves considered to be particularly stressful situations. Counterfactual thinking in 125 women sick‐listed due to chronic and widespread pain was investigated in terms of structure, function and control focus. The women were asked, for each of three types of problems that they indicated in a questionnaire to affect them most strongly, to describe a typical occurrence of it and to complete a counterfactual sentence in connection with it of the type ‘If only . . .’. The majority of counterfactuals pertained to predominantly somatic problems (e.g. musculo‐skeletal problems, pain and fatigue) classified as being affective rather than preparative and self‐focused rather than external, whereas in counterfactuals relating to predominantly psychological/psychosocial problems a preparative function and an external focus were more prominent. The numbers of problems listed and the numbers of situations responded to counterfactually were positively correlated. The counterfactuals, although often related to somatic problems, generally concerned psychological or psychosocial matters such as finances and paid or unpaid work. A contextual approach to elucidating counterfactual thinking based on subjects' own experiences is seen as providing valuable insight into what bothers them most.
