益胃汤加味方对原发性干燥综合征疲劳症状的影响

目的:探讨益胃汤加味对改善原发性干燥综合征(primary sj?rgren's syndrome,pSS)气阴两虚、瘀血阻络证患者疲劳症状及免疫学指标的治疗效果。方法:将116例原发性干燥综合征患者按照随机、对照、单盲法分为治疗组与对照组,每组58例。治疗组给予益胃汤加味方,每日1剂,2次/d;对照组给予硫酸羟氯喹200 mg/次,2次/d,两组均连续治疗24周。比较治疗前后两组患者中医证候疗效、中医疲劳症状积分、疲劳症状视觉模拟评分(visual analogue scale,VAS)以及类风湿因子(rheumatoid factor,RF)与血清免疫球蛋白G(immunoglobulin G,IgG)水平。结果:治疗后治疗组患者中医证候疗效优于对照组(Z=3. 712,P0. 05);治疗组中医疲劳积分与疲劳症状视觉模拟评分改善均优于对照组(P0. 05)。治疗6个月后,治疗组IgG水平较本组治疗前明显下降(P0. 05),与对照组组间比较差异无统计学意义。治疗后两组类风湿因子与本组治疗前比较均无明显下降。治疗组不良反应率1. 75%(1/57),对照组不良反应发生率为25. 49%(13/51)。结论:与硫酸羟氯喹相比,益胃汤加味方治疗pSS,可明显改善患者疲劳及总体症状,两者均可降低血清IgG,益胃汤加味方组疗效较硫酸羟氯喹更明显。两组药物对pSS患者RF水平均无明显影响。长期用药,益胃汤加味方治疗pSS较硫酸羟氯喹更为安全。     

光化学作用对肿瘤细胞胞吞大分子的释放

目的观察不同光敏剂在肿瘤细胞内的分布,以及光化学作用对肿瘤细胞胞吞大分子的释放作用.方法使用激光共聚焦显微镜观察ALA、ALA-HE、HMME、TPPSa2在肿瘤细胞SW480、K562的胞内分布,使用FITC-右旋糖酐观察肿瘤细胞对荧光标记大分子的胞吞作用,通过光照激发光敏化细胞,动态观察光化学作用前后胞吞大分子FITC-右旋糖酐的胞内分布变化.结果ALA、ALA-HE、HMME、TPPSa24种光敏剂均表现为胞质分布,核内分布少.ALA、ALA-HE的胞内分布主要表现为胞质内的弥散性荧光.HMME则表现为胞质内颗粒状荧光与弥散荧光同时存在.TPPSa2为典型的胞质内颗粒状荧光分布.光敏剂在SW480、K562两种肿瘤细胞的胞内分布没有明显差异.光照激发不同光敏剂对肿瘤细胞胞吞FITC-左旋糖酐的胞内分布影响不同.由TPPSa2及HMME活化而产生的光化学作用表现出明显的荧光颗粒重分布,ALA、ALA-HE则对胞吞荧光无明显重分布作用.结论不同光敏剂因其不同的理化性质而表现为不同的胞内分布.光化学作用可对肿瘤细胞胞吞大分子产生胞吞释放作用,其作用机制可能与光化学作用对胞吞泡的破坏有关.     

超高龄老年人脑损伤致伤因素分析及护理对策

目的 探讨老年人颅脑损伤的发病因素和护理措施.方法 对1999～2003年在解放军总医院定点就医的一组老年人群(年均18 492人)共210例颅脑损伤患者发病时的身体状况,发病率及受伤特点,病程及治疗和护理等临床资料进行回顾性总结.该组老年人在建档案时已被分为2个亚组:超高龄组年龄限(平均年龄79.75岁,1 978例)和老年组年龄限(平均年龄69.42岁,16514例).以同期其他人群的脑损伤187例作为对照组,并进行2组回顾资料的比较.结果 按意向处理分析397例均进入结果分析.发病率及受伤特点:超高龄组发病率明显高于老年组,多为摔伤;老年组和对照组均为交通伤占主要伤因.治疗及病程:对照组和老年组中均有超过80%患者接受手术治疗,而超高龄组仅有53.40%的患者接受手术治疗.预后:各组的死亡率和重残比率均无明显差别.结论 老年人群的脑损伤致伤原因主要是摔伤,同时多患有单器官或多器官的疾病;老年人脑损伤占用医疗资源多,但经积极治疗和采取有效的护理措施,仍可获得较好的疗效;回顾性资料记载超高龄组是能够检索到的国内外老年人脑损伤平均年龄最高的一组,对超高龄脑损伤的相关分析是有临床借鉴意义的.     

假体隆乳术后形态不佳的矫治

目的探讨假体置入隆乳术后形态不佳的原因和矫治方法。方法根据临床表现将乳房不佳分为5种类型：圆球型、上部膨隆型、下坠型、单侧双乳型及不规则型。通过松解纤维囊、纤维囊折叠缝合、重新分离隆乳腔隙、更换假体、乳房悬吊术等方法，进行矫治再次隆乳术。结果经过至少6个月随访观察，本组106例均获得了满意的手术效果。结论隆乳术后乳房形态不佳主要与假体体积过大、腔隙分离不到位、假体移位、乳房下皱襞过度分离、纤维囊挛缩及引流、包扎位置不当等因素有关，针对不同原因实施相应的手术方法矫治，能够获得满意的手术效果。     

高压氧综合治疗持续植物状态30例疗效分析

目的评估高压氧综合治疗持续植物状态的疗效和探讨最佳治疗方案。方法回顾性分析了1999年—2005年应用高压氧治疗的30例持续植物状态病例,主要分析了原发病因、高压氧治疗次数以及高压氧治疗时机与疗效的关系。结果脑外伤组显效率和好转率明显高于非脑外伤组(P<0.05),开始治疗时间≤30d组及31～60d组好转率明显高于≥61d组(P<0.05)。结论高压氧综合治疗对脑外伤所致持续植物状态患者60d以内开始行高压氧治疗的患者疗效较好。     

Validation of a simplified technique for using the POPQ pelvic organ prolapse classification system

Our objective was to determine the inter-examiner agreement of a simplified pelvic organ prolapse quantification (POPQ) exam and to assess its correlation with the standard POPQ exam. This study consists of two parts; both were preformed in a prospective, randomized, blinded fashion on women presenting with complaints attributed to pelvic organ support defects. The first study was done to determine the inter-examiner reliability of a simplified POPQ exam. The simplified POPQ exam is based on the POPQ with similar ordinal staging but with only four points measured instead of nine. Forty-eight women underwent exams by five different investigators. The order of exams was randomized and the examiners were blinded to the results of each other’s findings. The results of these two exams were compared using weighted kappa statistics. The second part of the study was done to determine the inter-system agreement between the simplified vs standard POPQ exam. A group of 49 women were examined by four different investigators: one using the simplified and the other using standard POPQ exams. The order of the exams was randomized and the examiners were blinded to the results of each other’s exam. Kendall’s tau-b statistics were used to determine the inter-system agreement. For the inter-examiner reliability of the POPQ exam, the average age was 60±13 years. The weighted kappa statistics for the inter-examiner reliability of the simplified prolapse classification system were 0.86 for the overall stage, 0.89 and 0.86 for the anterior and posterior vaginal walls, respectively, 0.82 for the apex/cuff, and 0.72 for the cervix. All demonstrate significant agreement. For the inter-system association between the simplified POPQ and standard POPQ, the average age was 61±15 year. The Kendall’s tau-b value for overall stage was 0.90, 0.83, and 0.87 for the anterior and posterior walls respectively, and 0.78 for the cuff/apex and 0.98 for the cervix. There is good inter-examiner agreement of a simplified POPQ classification system and it appears to have good inter-system association with the POPQ.IUGA Standardization of Terminology Committee members: Robert Freeman MD (chairman), Steven Swift, Eckhard Petri MD, Richard J.
