Effects of Electroacupuncture on the Number of NK-1R／IL-1β Double Labeled Immunofluorescent Positive Cells in th_e Epidermal and Subcutaneous Tissue Around the Ankle Joint of Adjuvant Monoarthritis in Rats

Adjuvant monoarthritis was induced by the injection of 50μl Complete Freund‘s Adjuvant（CFA) into ankle joint of adult SD rats. Electroacupuncture (EA)was performed on Huantiao (GB30)and Yanglingquan (GB 34) (0.5-1.5 v, 4-16 Hz, 30 min) after the injection.     

PTFV_1与左心功能不全、心房大小的关系探讨

目的:研究PTFV1与左心功能不全、心房大小的关系。方法:随机收集我院2004年5月至2004年8月64例门诊与住院患者数据,通过心电图检查根据PTFV1≤-0.02mm/s为标准,分为划分为PTFV1(+)组与(-)组。通过比较两组在左心功能、左心房大小的差异。结果:PTFV1(+)组与(-)组,两组在左心功能、左心房大小方面差异有显著性。结论:可以通过PTFV1是否大于或小于-0.02mm/s粗略估计左心功能、左心房大小。

The value of pulse wave velocity in the diagnosis of coronary heart disease

Objective: Using receiver operating characteristics (ROC) curve to evaluate the value of pulse wave velocity (PWV) in the diagnosis of coronary heart disease (CHD). Methods: By using coronary angiography as golden diagnostic standard of CHD, 218 patients were divided into both CHD group (n=121) and non-CHD group (n = 97). All these patients received PWV test. The efficacy of PWV of each artery segments in the diagnosis of CHD was evaluated by ROC curve. The sensitivity and specificity were calculated with the golden diagnostic standard of CHD. Results:The PWV of right carotid to femoral artery (Rc-f), left carotid to femoral artery (Lc-f), right radial to carotid artery (Rc-r), left radial to carotid artery (Lc-r) in CHD group were significantly higher than that of non-CHD group (9. 31±1. 75 vs 7.60±1.59, P<0. 01; 9. 02±1.71 vs 7. 52±1.50, P<0. 01; 8. 69±1. 37 vs 8. 00±1. 27, P<0. 01; 8.52±1. 03 vs 8. 03±1. 2, P<0. 01 respectively). However, the PWV of both right and left femoral to ankle artery (Rf-a and Lf-a) had no significant differences between the two groups. We then compared the area under curve (AUC) of each ROC(AUCROC) of PWV of Rc-f, Lc-f Rc-r and Lc-r to evaluate their diagnostic efficacy for CHD. We found that AUCROC of Rc-f PWV was the biggest (AUCROC = 0. 818), at the peak point of its ROC curve, the PWV was 8. 32 m/s. PWV>8. 32 m/s of Rc-f could predict the presence of CHD with a sensitivity of 79% and specificity of 77%. Conclusion: The PWV of Rc-f, Lc-f, Rc-r, Lc-r are significantly higher in CHD group than that in non-CHD group, and PWV of Rc-f is the most accurate in the detection of CHD. The PWV>8. 32 m/s of RC-F is a valuable predictor of CHD.

NP-HPLC测定阿敏-额尔敦中士的宁的含量

目的:建立蒙药阿敏-额尔敦中士宁含量测定方法.方法:采用正相高效液相色谱法.色谱柱为JapanInertsil(SIL 100A-5μm,4.6mm×150mm),流动相为正己烷-二氯甲烷-甲醇-浓氨试液(47.5:47.5:5:0.35),流速1mL·min-1,柱温:30℃,检测波长为254nm.结果:士的宁进样量在0.0918～0.459μg范围内呈良好的线性关系(r=0.9996),平均加样回收率为98.12%,RSD为0.87%.结论:采用正相高效液相色谱法测定士宁含量,方法简便、灵敏、准确,可作为蒙药阿敏-额尔敦的质量控制方法.     

无痛性心肌梗死1例

患者，男，76岁，因胸闷4h来诊。患者当日上午10时便后出现胸闷，无胸痛、心悸、气短、咳嗽、头晕、恶心、呕吐、出汗及大小便失禁等症状，含服硝酸甘油后缓解。无任何诱因13时后再次出现胸闷，亦无伴随症状，连续含服硝酸甘油及心痛定(量不详)后效果不明显，肌注杜冷丁1支几分钟后自觉胸闷有所缓解。在单位卫生所心电图检查示窦性心动过缓，心率46次／min，陈旧性前壁心肌梗死，Ⅰ、aVL导联ST段水平下移≥0．05mv，V5-6水平下移0．1mV，V1-6T波倒置，给予阿托品静注后窦性心动过缓消失，为进一步诊治急诊人院。     

急性正后壁心肌梗死的心电图诊断

急性正后壁心肌梗死，系指左心室的后基底部位，即位于在心室侧壁与下壁之间的左心房室沟下部的心肌梗死，由右冠状动脉的右侧支、后降支和／或左冠状动脉回旋支闭塞引起。左心室后壁心肌梗死，仅使QRS除极的前壁初始向量相对增大，在常规导联上不会出现异常Q波。有可能被漏诊或误诊，从而延误治疗。临床上单纯急性正后壁心肌梗死较
