老中青年急性心肌梗塞的临床特点及相关因素分析

急性心肌梗塞(acute myocardial infarction．AMI)是老年人常见的心血管疾病之一。但近年来，中青年AMI发病率有上升趋势，为了解各年龄段AMI的临床特点及其相关因素，现对某院近年来收住的AMI患者进行回顾性对比分析，现报告如下。     

硬膜外阻滞对高血压患者血压的影响

目的:比较未经正规治疗的高血压患者中位和低位硬膜外阻滞时对血压的影响。方法:有明确的高血压病史的急诊中上腹部手术麻醉病例42例(Ⅰ组)和下腹部手术麻醉病例47例(Ⅱ组),采用硬膜外阻滞后,比较手术时间、局麻药总量、麻醉后动脉血压下降的幅度和时相。结果:(Ⅰ组)手术历时62.3±17.8min,局麻药总量为利多卡因387.0±31.2mg,(Ⅱ组)手术历时56.8±14.9min,利多卡因总量366.7±30.1mg,均无显著差异。Ⅰ组硬膜外麻醉前平均动脉压为123.6±13.2mmHg,麻醉后最低的平均动脉压为69.5±10.0mmHg,出现最低平均动脉压的中位时间为26.3min,Ⅱ组麻醉前的平均动脉压为117.3±15.7mmHg,麻醉后最低平均动脉压为71.0±7.4mmHg,出现最低平均动脉压的中位时间为21.3min。两组在硬膜外阻滞后平均动脉压下降幅度及下降时间方面无显著差异。结论:未经很好控制的高血压患者硬膜外阻滞后均可引起血压急骤下降,低位硬膜外阻滞与中高位阻滞引起的血压下降幅度和时相相似。     

教育研究中的问题及评价

教育科学研究是探索和揭示教育过程中未被认识或未被完全认识的现象、本质和规律的一种活动。而问题研究又是教育科学研究的关键,能否选择一个真问题进行研究将直接决定教育科学研究的质量与成败。本文从问题的概念分析入手,从传统认识论中真理论的观点出发并综合多位学者的观点探讨了什么是真问题,最后粗浅地分析了教育课题研究中的真问题。     

A novel DRB1*09 allelic sequence in the Jing ethnic minority of China.

A new DRB1 allele, DRB1*0902, has been identified in an individual of the Jing ethnic minority. Its sequence was confirmed by sequencing of PCR products and clones. This allele differed by three nucleotides from DRB1*09012 at positions 157, 161 and 166, and resulted in amino acid motif substitution from VAES to DAEY.     

高效液相色谱法测定右旋儿茶素血浆浓度及药代动力学参数

本文建立了体液中右旋儿茶素的RP-HPLC测定方法。采用C_(18)键合相硅胶为填料的固相提取柱进行样品预处理,右旋儿茶素的提取回收率为79.8%.应用二极管阵列检测器对色谱峰纯度进行鉴定。该法精密度好,方法回收率近100%,日内、日间的变异系数为2.4～5.6%,血浓69.6～1160 ng/ml范围内呈线性关系,r=0.9993。家兔静注右旋儿茶素18mg/kg,其药代动力学过程符合二室模型,分布相半衰期为0.129 h,消除相半衰期为1.19h。     

The indication of surgical treatment of cerebellar hemorrhage]

61 patients with cerebellar hemorrhage were studied. The age at onset ranged from 15 to 84 years with a mean of 57.4 years. 49 cases were treated conservatively and 12 surgically and the mortality rates of the two groups were 32.5% and 25% respectively. Based on this study, it is suggested that the clinical and CT indications of surgical treatment of hematoma are as follows; Severe disturbance of consciousness; Bilateral eyeball fixation; Volume of hematoma over 10 ml; Size of hematoma over 4 cm in diameter; Marked acute obstructive hydrocephalus; Compression of cisterna ambieus and quadrigeminus.

Studies on the relationship between transaldolase activity and testosterone synthesis in Leydig cells of pubertalmice

Objective: To study the relationship between transaldolase activity, protein expression and testosterone synthesis in Leydig cells of pubertal mice. Methods: Leydig cells were cultured for 2 hours and 8 hours, to the Stimulation Group, hCG was added and to the Controls, only the vehicle. The testosterone concentration was then determined by enzyme-linked immunoadsordent assay (ELISA) and the transaldolase activity and protein expression by Western blot. Results: (1) Both the testosterone concentration and the transaldolase activity in both Stimulation Groups were significantly higher than those in the corresponding Controls (2 h: p<0.05-0.01; 8 h: P<0.001); (2) The ratios of the A isoform, the B isoform and the total transaldolase protein to β-actin between the Stimulation and Control Groups did not differ signifi-cantly. Conclusion: hCG stimulates the transaldolase activity as well as the testosterone synthesis in the Leydig cells of pubertal mice, indicating a positive relationship between them.
