目的 探讨某地区HIV/AIDS患者CD4+T淋巴细胞检测结果与抗病毒治疗效果,同时进行相关性分析。方法 2013年2月~2016年1月选择在笔者医院诊治的HIV/AIDS患者60例作为观察组,同期选择在笔者医院进行健康体检的健康人60例作为对照组,观察组都给予HAART标准治疗方案,观察组在治疗前后、对照组在入院时都进行CD4+T淋巴细胞与细胞因子表达的检测。结果 观察组外周血的CD4+CD45RA+、CD4+CD28+、CD4+CD45RO+的细胞比例明显低于对照组(P<0.05),两组CD4+CD25+的细胞比例对比,差异无统计学意义(P>0.05)。与对照组相比,观察组的血浆IL-10和TGF-β1含量都显著升高(P<0.05)。治疗后观察组的CD4+CD45RA+、CD4+CD28+、CD4+CD45RO+的细胞比例都明显上升(P<0.05),而血浆IL-10和TGF-β1含量明显降低(P<0.05)。在观察组中,Spearman秩相关分析显示CD4+CD45RA+、CD4+CD28+、CD4+CD45RO+的细胞比例与IL-10、TGF-β1水平均呈负相关(P<0.05)。结论 HIV/AIDS患者只有较低的免疫功能,具有较低的CD4+T淋巴细胞亚群比例和较高的IL-10和TGF-β1水平,HAART治疗能改善免疫功能,为此通过CD4+T淋巴细胞就能判断HIV/AIDS患者的治疗效果和病情。  相似文献

研究结核分枝杆菌热休克蛋白65(HSP65)对ApoE-/-小鼠Treg/Th17免疫平衡的影响。首先,将结核分枝杆菌HSP65蛋白免疫高脂饲喂ApoE-/-小鼠,再采用ELISA检测小鼠血清中抗HSP65抗体的产生情况,流式细胞术检测血中CD4+CD25+Foxp3+调节性T细胞(Treg)和CD4+IL-17+辅助性T细胞17(Th17)的数量,ELISA检测血清中IL-10、TGF-β1、IL-17和IL-21含量,生化分析仪检测血中总胆固醇(TC)、甘油三酯(TG)、高密度脂蛋白胆固醇(HDL-C)和低密度脂蛋白胆固醇(LDL-C)的含量,染色法计算动脉粥样硬化斑块面积。结果发现结核分枝杆菌HSP65蛋白诱导ApoE-/-小鼠产生了高水平的抗HSP65抗体,Treg细胞及其分泌的IL-10和TGF-β1细胞因子数量明显减少,Th17细胞及其分泌的IL-17和IL-21细胞因子数量明显增加,TC、TG、HDL-C及LDL-C的含量未见改变,但动脉粥样硬化斑块的面积明显增加。由此可见结核分枝杆菌HSP65蛋白能够破坏ApoE-/-小鼠Treg/Th17免疫平衡,促进动脉粥样硬化的发展。  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 blood pressure change with age in salt-sensitive teenagers whose salt sensitivity were determined by repeated testing.Methods Salt sensitivity was determined through intravenous infusion of normal saline combined with volume-depletion by oral diuretic furosemide in 55 teenagers. After five years, salt sensitivity was re-examined and subject blood pressure was followed up. Blood pressure changes in salt-sensitive teenagers were compared to that of non-salt sensitive teenagers over five years.Results After 5 years, the repetition rate of salt sensitivity determined by intravenous saline loading is 92.7%. In teenagers with salt sensitivity on the baseline, both the systolic blood pressure increments and increment rates were much higher than non-salt sensitive teenagers (12.7±12.1 mmHg vs. 2.8±5.2 mmHg, P< 0.01; 12.2%± 12.0% vs. 2.5% ±4.4%, P< 0.001,respectively). There was a similar trend for diastolic blood pressure (8.4 ± 6.4 mmHg vs. 3.7 ± 6.4 mmHg, P = 0.052; 13.2% ±10.6 % vs. 6.8%± 10.1%, P = 0.053, respectively).Conclusions Salt sensitivity determined by intravenous saline loading showed good reproducibility. Blood pressure increments with age were much higher in salt-sensitive teenagers than non-salt sensitive teenagers, especially in terms of systolic blood pressure.  相似文献
