成都地区3—16岁儿童,青少年恒牙生理成熟度研究

Dental maturity was studied in a group of 903 healthy children (boys: 465, girls: 438) born in Chengudu from 1972 through 1988. Dental maturity was estimated by the method of Demirjian and Goldstein, which is based on the development of seven left mandibular permanent teeth; teeth formation was studied. The standard and curves of dental maturity for Chengdu children (boys and girls) were constructed. At 3-5 years old, boys had their dental maturity slightly earlier than girls; there was no significant difference between boys and girls (P greater than 0.05). At the age of 7-14, girls were more advanced than boys (P less than 0.05). Developmental curves of seven left mandibular permanent teeth were plotted. The sexual difference was smaller at the crown developmental stage, and it increased during the root development. In all, girls were more advanced by 0.45 year than boys. The maximum average difference was 0.85 year for the canine. The time that each developmental stage has taken was shorter in 50% of girls as compared with that in boys, and it was longer in 28% of girls. There was no difference between boys and girls in the remaining 22% of cases.

阿斯匹林引起小儿十二指肠穿孔一例报告

患儿,男性,11岁,因感冒口服阿斯匹林,每日三次,每次0.6g,三日后突然上腹疼痛伴恶心、呕吐,第四日来我院就诊。患儿既往健康,无胃病史。入院体检:体温37.4℃,脉搏94次/分,呼吸20次/分,血压90/60mmHg,神志清楚,咽略充血,心肺无殊,腹肌紧张,全腹压痛反跳痛明显,肝浊音区消失,中上腹部叩诊呈鼓音,肠鸣减弱;红细胞485万/mm~3,血红蛋白13g/dl,白细胞16000/mm~3,中性88%,淋巴12%;胸腹透视见心肺正常,右膈下有新月状透光区。诊为上消化道穿孔并弥漫性腹膜炎,立即硬膜外麻醉下剖腹探查,见腹腔大量黄色渗出液,共     

乌拉坦和硫酸链霉素对听觉传导的联合阻滞作用

选用30只耳廓反射正常的白色红目雄性豚鼠，随机分成三组。分别单独或联合肌注乌拉坦、硫酸链霉素（SM），观察比较三组豚鼠的耳蜗电位（CM）和听性脑干反应（ABR）结果，发现乌拉坦可使动作电位（AP）之N1波及ABR之I波潜伏期和Ⅰ-Ⅳ波间期延迟，乌拉坦和SM联合用药对听觉传导的阻滞明显加强，提示乌拉坦不宜作为观察听觉传导时间动物实验的麻醉用药。     

古老的民间体育游戏——踢毽子

踢毽子是一种民间较为流行的体育游戏。毽子用鸡毛插在圆形底座上做成,踢法多种多样。清·富察敦崇《燕京岁时记》:“毽儿者,垫以皮钱,衬以铜钱,束以雕翎,缚以皮带。”高承·《事物纪源》:“今时小儿以铅锡为钱,装以鸡羽,呼为鞬子,三五成群走踢。” 据高承《事物纪源》记载,踢毽子源于蹴鞠。西汉·刘向《别录》:“蹴鞠者,传黄帝所作,或曰起战国之时。”可见,踢毽子可追溯到战国以前。 相传,此项游戏流行于南北朝时期,明代以     

保肝精在肝硬化腹水治疗中增效作用的观察

笔者对单用西药利尿剂及支持疗法效果不佳的肝硬化腹水患者２８例，加用中药强肝无糖颗粒剂与食疗剂保肝精治疗，取得良好效果，显效率７１４％，总有效率９２９％。同时，以单加用强肝无糖颗粒剂治疗１５例为对照组，其显效率３３３％，总有效率７３３％。通过临床观察表明，食疗剂保肝精在肝硬化腹水治疗中有较大的增效作用。     

Fanconi's贫血的细胞遗传学诊断方法探讨

Faneoni's贫血(FA)是一种少见常染色体隐性遗传疾病,临床表现全血减少、骨髓增生低下、生长发育迟缓、智能低下等多发性先天缺陷,伴有染色体畸变。自1927年范可尼首次报道以来,国内外有少     

小儿慢性食管炎

作者对不同年龄组的小儿做过25,000次上消化道纤维内窥镜检查,结果食管炎的检出率为10～12%,男孩占61%,女孩为39%。对10天～15岁的571例小儿食管炎进行分析表明单纯性食管炎较其它各种非感染性消化道疾病并发的食管炎罕见。食管炎在新生儿期已开始发病,但学龄期儿童最常见。
