108例骨髓增生异常综合征患者WHO分型及国际预后评分系统与生存期的关系研究

目的研究骨髓增生异常综合征(myelodysplastic syndrome,MDS)患者的WHO分型及国际预后评分系统(IPSS)与生存期的关系。方法分析我院自2005年11月至2011年7月初治108例MDS患者的临床资料。将入选MDS例患者分别按WHO(2001)分型标准及IPSS评分系统进行分组,比较各组患者生存情况。结果根据WHO分型及IPSS分型,各组中位生存期均不同,WHO分型中难治性贫血(RA)、难治性血细胞减少伴多系增生异常(RCMD)与RA伴有原始细胞过多(RAEB)之间生存率差异有统计学意义(P值均<0.05),RAEB-1与RAEB-2之间生存率差异有统计学意义(P<0.05)。IPSS低危组与中危一I组生存率差异无统计学意义(P>0.05),其余各组问差异有统计学意义(P<0.05)。结论 WHO分型结合IPSS能有效评估MDS患者病情及预后,对选择合适的治疗方案和提示预后具有重要意义。     

血清铁蛋白、乳酸脱氢酶、β2微球蛋白检测对骨髓增生异常综合征的临床意义

目的观察血清铁蛋白(SF)、乳酸脱氢酶(LDH)、β2微球蛋白(β2-MG)在骨髓增生异常综合征(MDS)患者不同亚型中的水平及临床意义。方法将入选病例根据WHO分型,速率法测定LDH水平,化学发光免疫法测定SF和β2-MG水平,比较在MDS不同分型中的水平以及在不同IPSS评分患者中的水平差异有无显著性。结果MDS与正常对照组血清SF、LDH、β2-MG水平有显著差异(P<0.05);MDS组间比较结果:伴多系病态造血的难治性血细胞减少症(RCMD)组、难治性贫血伴原始细胞增多症(RAEB)组SF、LDH、β2-MG水平均明显高于其他组。SF、β2-MG在RCUD组与RCMD组无显著差异;虽然不同IPSS评分患者中,SF、LDH、β2-MG水平随危险度增加而增高,但患者比例不尽相同,综合分析可能有助于MDS预后评估。结论 MDS是一组造血干细胞肿瘤性疾病,其血浆SF、LDH、β2-MG水平与分型及IPSS评分有一定相关性,检测上述指标对MDS的诊疗及预后评估有一定临床意义。

的进展类型RAEB患者骨髓细胞中高表达,CD133有助于RAEB分型诊断;而CD34+/CD38-标记在MDS分型诊断中并无
价值。

［摘 要］ 目的：检测骨髓增生异常综合征（MDS）患者骨髓组织中SHIP、Caspase-3 mRNA的表达,探讨其表达与MDS发病及向白血病转化过程的关系。方法：根据国际预后评分系统（IPSS）选择62例MDS患者,其中低危（low-risk）组20例、中危1（Int-1）组12例、中危2（Int-2）组13例和高危（high-risk）组17例,采用RT-PCR法检测62例MDS患者及30例健康正常者(对照组)骨髓单个核细胞(BMNC)中SHIP mRNA及Caspase-3 mRNA的表达水平,并分析两者之间的关系。 结果：MDS低危组和中危1组BMNC中SHIP mRNA表达率（100%,100%）及表达水平(4.467±2.899,4.529±1.975)分别与对照组（100%,4.623±2.979）比较差异均无统计学意义（P>0.05）;在中危2组和高危组中,BMNC中SHIP表达率（92%,88%）下降,表达水平(2.124±1.880,2.574±1.807)低于对照组（P<0.05）。Pearson相关分析,MDS患者BMNC中SHIP mRNA与Caspase-3 mRNA表达水平呈正相关关系（r=0.714,P<0.05）。随骨髓原始细胞比例升高,SHIP mRNA表达水平降低(F=3.7,P<0.05) ,不同性别（t=0.940,P>0.05）、不同年龄（t=1.419,P>0.05）患者SHIP mRNA表达水平差异无统计学意义。 结论：SHIP在高危MDS患者BMNC中呈低表达或不表达,其表达水平可以作为判定MDS预后的一个指标。     

骨髓增生异常综合征患者骨髓铁调素水平的研究

目的 研究铁调素及其相关因素对骨髓增生异常综合征（MDS）患者铁过载水平的评估价值。方法 选取64例MDS患者,采用ELISA法对患者的外周血和骨髓铁调素水平进行测定;Real-Time PCR法测定骨髓生长分化因子15（GDF15）和扭转原肠胚形成同系物1（TWSG1）mRNA的表达;流式细胞仪对T淋巴细胞亚型（CD4+、CD19+）和极化进行测定;采用磁共振成像T2*（MRI T2*）技术对心脏和肝脏铁沉积程度进行测定;结合患者的血清铁蛋白（SF）、C反应蛋白（CRP）和促红细胞生成素（EPO）资料,对数据进行分析。结果 64例MDS患者外周血与骨髓的铁调素表达水平无明显差异（P=0.134）。根据WHO 2008分型分组,难治性贫血伴环形铁粒幼细胞增多（RARS）亚型的骨髓铁调素表达水平最低[（105.40±5.13）ng/mL],难治性贫血伴原始细胞增多（RAEB）亚型的骨髓铁调素表达水平最高[（335.71±25.16）ng/mL],各组间比较差异有统计学意义（P=0.041）。根据IPSS积分和WPSS积分分组,低危组和高危组骨髓铁调素表达水平比较差异均有统计学意义（P<0.05和P<0.01）;但与WPSS低危组相比,WPSS高危组的SF和GDF15 mRNA均明显高表达（P<0.05）,而IPSS低危组与高危组比较差异无统计学意义（P>0.05）。根据T淋巴细胞亚型和极化分组,CD4+高表达组骨髓铁调素水平较正常组高（P<0.05）;CD19+高表达和正常组间骨髓铁调素水平比较无统计学意义（P=0.206）;Th1/Th2>70.6组骨髓铁调素水平高于Th1/Th2≤70.6组（P<0.001）。将铁调素与SF、心脏T2*值、肝脏铁浓度（LIC）（由肝脏T2*值换算得到）做逐步回归分析,仅有LIC水平与铁调素存在相关性（r=0.582,P<0.001）。结论 炎症对于调节铁调素表达至关重要,T淋巴细胞的活化及极化趋势可能在其中起到部分作用。MRI T2*对于评估MDS患者铁过载水平的效能优于SF。

Value of D-Dimers in patients with acute aortic dissection

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.     

Research of combined liver-kidney transplantation model in rats

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.

BLOOD PRESSURE CHANGE WITH AGE IN SALT-SENSITIVE TEENAGERS

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.     

Development on Adjustable Calibration Marker for Shock Wave Focus

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.     

Study on the TCM Pathogenesis of Angiopathic Complications of Type II Diabetes

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.     

Leptin, Ghrelin and TNF-α before and after Hypo-caloric Traditional Chinese Diet and Auricular Acupuncture

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
