上颌双侧磨牙形态异常1例

正常上颌第一、第二磨牙有独特的外形特征 ,尤其上颌第一磨牙 ,其牙冠外形和牙根数目都比较恒定。然而 ,笔者最近发现 1例 ,患者的上颌双侧第一磨牙、左侧第二磨牙牙冠及牙合面形态与常见的同名牙有明显差异 ,且牙根数目均为4个。笔者观察其牙冠牙合面形态与牙根数目可能有相关

广东省梅县重点人群碘营养状况调查分析

Objective To estimate the present salt iodine content and iodine nutrition need of high risk population of iodine deficiency disorder in Meixian County. Methods Each primary school was selected from urban and rural areas(Xiyang Town, 20 kilometers away from Meixian County), the goiter rate of 8 to 10 year-old students was examined and urinary iodine and household salt iodine was sampled. Twenty to 40 year-old women of childbearing age nearby schools around the urban and villages around Xiyang Town were selected to collect their urine and salt samples. At urban hospitals and rural health centers, 0 to 2 year-old infant urine samples were collected, Thyroid gland was palpated and urinary iodine was determined by iodine in urine by As3+-Ce4+catalytic spectrophotometry, salt iodine was determined by direct titration. Results The goiter rates of 8 to 10 year-old students were 1.5 % (3/200), 1.0% (1/100) for the urban area and 2.0% (2/100) for rural area. Median of urinary iodine in 8 to 10 year-old students, infants, women of childbearing age averaged at 237.1 μg/L and 280.1, 234.7,187.6 μg/L respectively, with each being 287.4,245.0,205.5 μg/L in urban area and 278.9,228.5,176.4 μg/L in rural area. Women of childbearing age had a higher percentage of urinary iodine < 50.0 μg/L than students,students had a higher percentage than infants, each being 7.5%(15/200), 4.5%(9/200), 4.0%(4/100). The ration of urinary iodine > 300.0 μg/L was more in infants than in students, that in students was more than that in women of childbearing age, each being 33.0% (33/100), 30.0% (60/200),22.5% (45/200). The median of salt iodine was 27.2 mg/kg. The coverage of iodized salt was 100.0%(400/400). Ninty-seven percent(194/200) and 96.0% (192/200) of qualified iodized salt were consumed in urban area and in rural area. Conclusions The amount of iodine added to salt meets the requirement in the 3 kinds population risk of iodine deficiency disorder. But a higher iodine status has been found out in students and infants. It is reasonable to decrease the present salt iodine content.     

滥用抗生素致喉真菌病3例报告

喉部真菌病很少见,大多由口腔、咽部及鼻部真菌感染而继发。近年来,真菌病特别是深部真菌病的发病率有了明显的增加,其原因与大量抗生素的广泛应用有关。本文报告3例因滥用抗生素所致的喉真菌病,旨在使临床医生能够正确应用抗生素。1临床资料病例1:患者女,50岁。因声音嘶哑、咽     

妊高征与眼底视网膜病变的临床探讨

目的 :探讨妊高征患者临床特征与视网膜病变的关系。方法 :观察 2 2 0例妊高征患者的眼底情况。结果 :视网膜病变与水肿关系不密切 ,与平均动脉压、蛋白尿的严重程度、病程及红细胞压积有密切关系 ;有眼底改变者 118例 ,占 5 0 .3%。结论 :眼底镜检查是临床上借以了解视网膜血管的常用方法 ,并可反映妊高征病情的程度 ,为产程处理提供依据     

骨科会客室

本刊:请您谈谈对骨质疏松性骨折的认识? (?)德明教授:随着社会的老龄化,骨质疏松症已经成为骨科医师日常临床诊疗工作的重要内容。除骨骼本身退化的因素外,老年人视力、听觉等感觉器官功能衰退及神经系统、运动系统功能退化,使老年人跌倒和外伤的几率明显高于年轻人,骨折往往成为骨质疏松症患者首次就诊的原因。因此在骨科的临床诊疗工作中,对于骨质疏松症性     

经皮穿刺椎体成形术围手术期护理

目的探讨椎体成形术治疗胸腰椎压缩性骨折、胸腰椎椎体良恶性肿瘤、症状性胸腰椎体血管瘤的护理。方法对我科30例应用经皮椎体成形术治疗脊柱疾病的患者,实施术前心理护理和检查配合,术后加强生命体征的观察、防止并发症的发生及术后康复指导等措施。结果30例术后2~48小时疼痛明显缓解,甚至完全消失,30例患者均无并发症发生。结论经皮椎体成形术是治疗胸腰椎压缩性骨折、胸腰椎椎体良恶性肿瘤、症状性胸腰椎体血管瘤安全有效的方法,可迅速减轻疼痛并改善功能,而细致周到的护理是手术成功的保障。     

丙戊酸钠合并氯丙嗪治疗精神分裂症的对照研究

目的观察丙戊酸钠合用氯丙嗪治疗精神分裂症的疗效与不良反应。方法符合CCMD-3诊断标准的精神分裂症住院患者,丙戊酸钠合用氯丙嗪组(研究组)35例,单用氯丙嗪组(对照组)31例。以PANSS、CGI、TESS量表评定观察12周。结果研究组总体疗效自第2周起明显优于对照组(P<0.05),其中研究组兴奋症状分及攻击因子分自第4周起缓解明显优于对照组(P<0.05)。研究组较对照组副反应较少且程度较轻(P<0.05)。结论丙戊酸钠合并氯丙嗪治疗精神分裂症疗效肯定,安全性与耐受性较好。     

接种浓度对人骨髓基质干细胞在脱钙骨上生长和分布的影响

目的研究不同接种浓度对人骨髓基质干细胞在脱钙骨支架上生长过程及分布的影响.方法荧光活性染料DiI标记人骨髓基质干细胞,接种于部分脱钙骨支架材料上,测定细胞的粘附率;将细胞悬液浓度分别调整为20×106、10×106、5×106/mL和空白组,依次接种于同一块脱钙骨支架4个相邻象限的中心位置上.接种后第2、7 d在倒置荧光显微镜下观察材料表面的细胞分布、生长的情况,测量细胞材料面积比.结果 DiI标记的骨髓基质干细胞的粘附率为(99.9±0.2)%,未标记的骨髓基质干细胞粘附率为(99.1±1)%,两者无统计学差异(P＞0.05).不同浓度细胞的细胞材料面积比无差异(P＞0.05).结论通过DiI标记可以动态观察细胞在材料上的生长状况.20×106、10×106、5×106/mL接种浓度均能达到覆盖脱钙骨表面直接接种部位的目的.
