为测定亚急性重症乙型肝炎患者血浆中纤维蛋白原的浓度与纤维蛋白单体聚合能力,以了解其凝血功能。用蕲蛇酶水解纤维蛋白原,用计算机测定其相关数值。发现20名亚急性重症乙型肝炎患者,其纤维蛋白聚合反应速率为(0.315±0.065)g/min;最大吸光度为(0.176±0.035)OD;纤维蛋白原浓度为(150±30)mg/dl;纤维蛋白单体聚合反应速率/最大吸光度比值为1.789±0.160;反应延滞时间为(-21±5)s。结果表明亚急性重症乙型肝炎患者的纤维蛋白原反应时间增快,但其它各项指标均下调,表明患者出血与凝血功能受损。  相似文献

目的 制备pH敏感聚乙二醇-聚己内酯-聚甲基丙烯酸-N,N-二乙氨基乙酯(mPEG-PCL-PDEAEMA)载胰岛素缓释纳米粒,考察其体外释放效果和体内降糖活性.方法 结合开环聚合反应和原子转移自由基聚合反应合成具有不同疏水链段的mPEG-PCL-PDEAEMA,用傅里叶红外光谱和核磁共振氢谱表征其结构;采用纳米沉淀技术制备聚合物载胰岛素纳米粒,动态光散射法测定粒径,透射电子显微镜观察其形态;BCA法测定载药情况,并考察其体外释放行为;建立糖尿病大鼠模型,监测给药后血糖水平.结果 在pH1.2~7.4时,聚合物纳米粒的粒径随pH增大而减小.以90%wt投药比制备mPEG5k-PCL13k-PDEAEMA10k和mPEG5k-PCL10k-PDEAEMA10k载胰岛素纳米粒时的包封率和载药率为最佳,包封率分别为(81.99±1.77)%和(53.12±0.62)%,载药率分别为(42.46±0.53)%和(32.34±0.26)%,粒径分别为181.9±6.67 nm和169±7.1 nm.体外释放结果显示聚合物载胰岛素纳米粒具有出色的缓释行为,并且随着疏水链段的增长,药物释放速度减慢.体内药效实验表明mPEG5k-PCL13k-PDEAEMA10k载胰岛素纳米粒能够在体内保持48 h的降血糖效果,较游离胰岛素的降糖作用时间明显延长.结论 pH敏感三嵌段聚合物mPEG-PCL-PDEAEMA有望成为理想的胰岛素缓释载体.  相似文献

Objective: To evaluatel the value of D-dimers in patients with acute aortic dissection (AAD). Methods: This study consisted of 16 patients with AAD and 27 non-AAD patients. Serum D-dimets were measured by Sta-Liatest D-DI immunoturbidimetric assay. Results: D-dimer level was higher (P < 0.001) in patients with AAD(7.91 ± 5.52 μg/ml) than that in non- AAD group(1.57±1.24 μg/ml). D-dimer was positive (>0.4 μg/ml) in all patients with AAD and in 10 control group patients (37%). Among patients with acute AAD, D-dimers tended to be higher in Stanford A than in Stanford B (8.67 ± 4.31 μg/ml vs. 3.24±1.27 μg/ml, P <0.01). D-dimer values tended to be higher in more extended disease(3.84 ± 1.65 μg/ml, 8.57 ± 3.58 μg/ml and 11.87 ± 5.69 μg/ml in thoracic aorta, thoracic and abdominal aorta, thoracic and abdominal aorta and iliacal arteries, respectively, P < 0.05 for both 8.57 ± 3.58 and 11.87 ± 5.69 vs. 3.84 ± 1.65 ). Including the control group into the analysis, we found a sensitivity of 100%, a negative predictive value of 100%, and a specificity of 66% and a positive predictive value of 64% for D-dimer in diagnosis of AAD in our patients with suspected AAD. Conclusion: D-dimer was elevated in patients with AAD. A negative D-dimer test result could be useful in excluding AAD.  相似文献

Objective: To set up a simple and reliable rat model of combined liver-kidney transplantation. Methods: SD rats served as both donors and recipients. 4℃ sodium lactate Ringer's was infused from portal veins to donated livers,and from abdominal aorta to donated kidneys, respectively. Anastomosis of the portal vein and the inferior vena cava (IVC) inferior to the right kidney between the graft and the recipient was performed by a double cuff method, then the superior hepatic vena cava with suture. A patch of donated renal artery was anastomosed to the recipient abdominal aorta. The urethra and bile duct were reconstructed with a simple inside bracket. Results: Among 65 cases of combined liver-kidney transplantation, the success rate in the late 40 cases was 77.5%. The function of the grafted liver and kidney remained normal. Conclusion: This rat model of combined liver-kidney transplantation can be established in common laboratory conditions with high success rate and meet the needs of renal transplantation experiment.  相似文献

Shock wave lithotripsy (SWL) is a treatment of choice for upper urinary stones. However, this procedure is inappropriate for obese patients because the focus is often unable to reach the target owing to the limited focal distance in shock wave source. Although treating such patients in a blast path may increase the application length of shock wave source, it's difficult to find this path on the lithotripter monitor. For this reason, we invented an adjustable calibration marker in order to set an effective focus in the shock wave hath.  相似文献

Excess production of reactive oxygen species(ROS)of mitochondrion mediated by hyperglycemia is the common pathogenesis of angiopathic complications of diabetes.TCM holds that the damp from the dysfunction of spleen.kidney and liver is the causative factor of complications of diabetes.This is similar to the mechanism of Ros resulting in angiopathic complications of diabetes.When the angiopathic complications of type II diabetes mellitus(T2DM)are difierentiated as caused by turbid damp in TCM can be explained as ROS.Since the obstruction of pathogenic damp in channels and collaterals is said to be the main pathogenesis,the treating principle should be dissolving the damp to remove the obstruction.  相似文献

INTRODUCTION Obesity is a complex emergent problem, which can be possibly solved not only by the diet but also by the life style and promotion of a constant physical exercise. 1, 2 No doubt careful attentions must be given to the nutritional condition of obese people, the dietary habits, the somatic build (i.e. distribution of fat mass) and the organic functions linked to formation of the fat mass. All the parameters should be constantly monitored before, during and after a diet treatment. 3, 4, 5  相似文献

Objective: To observe the therapeutic effects in acupunture treatment of primary dysmenorrhea combined with spinal Tui Na, and study its mechanism. Methods: Thirty cases of the treatment group were treated by acupuncture combined with spinal Tui Na, and thirty cases in the control group were treated by routine acupuncture. Results: The total effective rate was 93.3% in the treatment group, and 73.3% in the control group, with a significant difference between the two groups (P<0.05). Conclusions: Acupuncture combined with spinal Tui Na has good prospects for treatment of primary dysmenorrhea.  相似文献

In treating chronic nephropathy,Luo Lingjie,a chief physician,pays attention to regulating the balance between yin and yang,treating infection if present,and removing pathogenic factors.He prescribes gentle drugs and uses carefully strongly warming-tonifying ones,emphasizes the importance of persuading the patient to persist in treatment with medication and nurse one's health for recuperation,and is good at combined use of TCM and western medicine therapy and brings the merits of various therapies into full play,with obvious theraoeutic effects.  相似文献
