聪耳通窍汤联合耳针对老年神经性耳鸣近远期疗效观察

目的探讨聪耳通窍汤联合耳针治疗老年神经性耳鸣患者的近远期疗效。方法选取耳鼻喉科门诊收治的老年神经性耳鸣患者136例,按随机数字表法分组,对照组68例予以耳针治疗,研究组68例在对照组基础上予以聪耳通窍汤治疗。检测比较两组间近、远期临床疗效、甲襞微循环指标、血液流变学指标以及不良反应发生率。结果治疗后,对照组总有效率为67.64%(46/68)低于研究组总有效率83.82%(57/68),具有统计学意义(P<0.05);随访6个月后,对照组总有效率64.71%(44/68)低于研究组总有效率89.71%(61/68),具有统计学意义(P<0.05);与对照组比较,研究组治疗后甲襞微循环襻周积分、管襻积分、流态积分及总积分较低,治疗后血浆黏度、高切全血黏度、低切全血黏度及红细胞压积较低,差异具有统计学意义(P<0.05);治疗中出现的不良反应为恶心、腹胀、针刺部位疼痛,两组间不良反应发生率无统计学差异(P>0.05)。结论聪耳通窍汤联合耳针治疗老年神经性耳鸣患者的近远期疗效均较好,能明显改善患者微循环状态及血液流变学指标,减轻内耳循环障碍,具有较高安全性。     

粤西地区血小板聚集率正常人群参考范围的建立

目的 :为粤西地区血小板聚集率的临床检测提供参考标准。方法 :采用北京普利生仪器有限公司生产的 L BY-NJ型多功能血液凝聚仪。以终浓度 2 .5 μmol/ L ADP为诱导剂 ,对 6 38例正常人按年龄、性别分组 ,分别检测血小板 1m in、3min、5 min及 Max聚集率 ,并进行统计学分析。结果 :各年龄组男女性别 PAG无显著性差异 ( P>0 .0 5 ) ;小于 35岁年龄组与 35～ 5 5岁年龄组比较 ,PAG无显著性差异 ( P>0 .0 5 ) ;35～ 5 5岁年龄组与大于等于 5 5岁年龄组比较 ,1min及 3mim PAG存在显著性差异 ( P<0 .0 5 )、5 min及 Max PAG相差非常显著 ( P<0 .0 1) ;小于 35岁年龄组与大于等于5 5岁年龄组比较 ,PAG有非常显著性差异 ( P<0 .0 1) ;小于 5 5岁年龄组与大于等于 5 5岁年龄组比较 ,PAG差异有极显著性意义 ( P<0 .0 1或 P<0 .0 0 1)。结论 :5 5岁以上年龄组与 5 5岁以下年龄组的 PAG结果 ,可作为粤西地区同类方法PAGT的正常参考值供临床检测参考     

结节性硬化病的CT诊断

目的:探讨结节性硬化(TS)的病因与诊断标准以及CT诊断、分析思路和鉴别诊断。方法:采用CT平扫和增强扫描方法,对3例患者行头部及肾脏检查。结果:3例中伴室管膜下巨细胞星形细胞瘤1例,伴双肾血管平滑肌脂肪瘤1例,另1例孕妇伴双肾血管平滑肌脂肪瘤破裂出血。结论:CT检查对于TS有其特征性表现,基于本病多器官的组织缺陷和错构瘤为特征的系统性疾病特点,优化扫描方案是提高诊断正确率的关键。     

Variants of lymphoid lines produced with ricin A-chain monoclonal antibody conjugates

Conjugates of ricin A-chain with monoclonal anti-light chain antibodies specifically killed cells hearing kappa or lambda immunoglobulin (Ig) light chains. Exposure of cells from B-lymphoblastoid cell lines (B-LCL) to conjugate for less than 30 h had only a slight effect on cell growth, but on 48 h exposure a marked killing effect was achieved. After recovery of growth, cells were re-exposed to conjugate for 9-14 days. Treatment of cells from the EB4 line (sIgG lambda) in this way yielded 4 variants which showed a marked reduction in levels of surface Ig lambda and secreted Ig lambda with slight, or no, reduction in MHC class II expression and similar growth rates to the parent line. Variant lines retained their phenotype over long periods of culture.     

Vulvovaginal candidiasis among symptomatic women of childbearing age attended at a Medical Analysis Laboratory in Franceville,Gabon

BackgroundVulvovaginal candidiasis (VVC) is one of the most common lower genital tract infections in women; this unpleasant and extremely embarrassing pathology is one of the main reasons for gynaecological consultation. In Gabon, the prevalence of VVC remains poorly described even though VVC is known to be the leading gynaecological condition in several countries. This retrospective cross-sectional study sought to assess the prevalence of VVC among symptomatic women in southeastern Gabon.MethodsClinical samples were collected from patients suspected to have VVC during a 2-year period (from January 2016 to December 2017). Gram staining of vaginal smears provided indications of vaginal flora and confirmed the presence of yeast. Sabouraud-chloramphenicol and chromID Candida media were used to isolate yeast, and species identification was performed using morphological tests and the Vitek 2 Compact automated system.ResultsFor the 873 patients included in this study, the prevalence of VVC was 28.52%. Eleven Candida species were identified, with greater representation of Candida albicans (82.73%) than of Non C. albicans candida (NCAC) (17.27%), which were distributed as follows: Candida famata (4.02%), Candida spp. (3.61%), Candida rugosa (3.21%), Candida lipolytica (1.61%), Candida parapsilosis (1.61%), Candida glabrata (1.21%), Candida tropicalis (0.80%), Candida krusei (0.40%), Candida dubliniensis (0.40%), and Candida sphaerica (0.40%).ConclusionThis study offers the first estimation of VVC among Gabonese women in childbearing age with the symptoms. It showed that VVC is very common in Gabon. C. albicans as the most commonly represented species.     

基诺族睡眠状况调查及分析

目的:了解基诺族睡眠的一些基本情况、失眠症的发生率和治疗情况.方法:使用自拟的"基诺族睡眠情况调查表",通过入户调查和现场访谈对126名基诺族人进行调查.结果:随年龄增长基诺族人的睡眠时间渐减少.<30岁年龄组有午睡习惯的比例高于30岁以上年龄组,差异有统计学显著性.34.12%(43人)符合失眠症诊断,失眠原因以各种精神疾病(41.86%)和酒依赖(30.23%)最为常见.失眠患者中, 就诊率为25.58% (11例).结论:基诺族睡眠的基本情况与国内其他人群相比有一些共同之处;失眠发生率较高,但由于本研究样本量和样本选择的不足,此结果还需进一步证实.
