应用氢质子磁共振波谱技术研究女性雌二醇与海马区细胞代谢物的相关性及其意义

目的应用氢质子磁共振波谱(~1H-MRS)研究女性雌二醇与海马区细胞代谢物间的相关性及其意义。方法选取2015年10月至2016年6月深圳市龙岗中心医院妇科门诊围绝经期女性15例作为围绝经期组,同期选择体检中心健康年轻女性15例作为健康年轻女性组,均收集两组受试者年龄、体质指数、受教育年限等一般资料;应用3.0 T1H-MRS检测双侧海马体部的N-乙酰天冬氨酸(NAA)、总肌酸(Cr)、胆碱(Cho)等代谢物浓度,测定两组受试者血清雌二醇水平。结果围绝经期组雌二醇低于健康年轻女性组[(20.07±11.12)ng/L比(43.82±10.48)ng/L](P<0.05)。围绝经期组右侧海马NAA/Cr、Cho/Cr低于健康年轻女性组(1.15±0.22比1.40±0.23,1.12±0.18比1.27±0.15)(P<0.05)。Pearson相关分析:30例女性左侧海马和右侧海马NAA/Cr与雌二醇呈正相关(r=0.395,P=0.031;r=0.520,P=0.003);左侧海马NAA/(Cr+Cho)和右侧海马NAA/(Cr+Cho)与雌二醇呈正相关(r=0.465,P=0.010;r=0.466,P=0.009)。左侧NAA/Cr、左侧NAA/(Cr+Cho)、右侧NAA/Cr与年龄呈负相关(r=-0.445,P=0.014;r=-0.398,P=0.029;r=-0.466,P=0.010)。右侧NAA/(Cr+Cho)、右侧NAA/Cr与体质指数呈负相关(r=-0.430,P=0.018;r=-0.363,P=0.049)。结论女性血清雌二醇水平越高,大脑海马体部NAA/Cr越高,血清雌二醇可能通过某种机制影响海马区细胞的代谢,且双侧海马体部NAA/Cr值随着年龄增长而降低。

【摘要】 目的 探讨轻度认知功能障碍（MCI）患者认知功能相关脑区弥散参数的定量大小及其与临床指标的相关性,为MCI的弥散张量成像（DTI）影像诊断提供参考指标。方法 采用DTI检测纳入研究的21例MCI患者双侧海马、双侧海马旁回、双侧后扣带回、双侧额中回及双侧颞中回认知功能相关脑区弥散各向异性参数（FA）、平均弥散量（MD）的均值、标准差。计算脑区内FA、MD均值与MoCA、MMSE认知功能评分的相关性。结果 定量确定了认知相关脑区内的FA、MD值及变化范围。MCI患者右侧后扣带回的FA值均值与MoCA、MMSE评分呈正相关;左侧海马、右侧额中回、左侧颞中回的FA值均值与MMSE呈负相关;左侧海马、左侧海马旁回、右侧颞中回的MD值均值与MMSE评分呈正相关;左侧海马旁回的MD值与MoCA评分呈正相关,上述相关性分析结果均具有统计学意义（P＜ 005）。结论 DTI各参数指标定量范围的确定可以为MCI的早期诊断提供一定的量化诊断依据;左侧海马、左侧海马旁回、右侧后扣带回、右侧额中回及双侧颞中回可能是MCI影像诊断重点关注的脑区。     

原发抑郁症与脑卒中后抑郁症患者的海马形状分析

目的探讨原发抑郁症患者与脑卒中后抑郁症患者的海马形状改变模式的区别。方法选取22例脑卒中后抑郁症（PSD）患者、15例原发抑郁症（PD）患者及29例正常对照者,使用计算机自动分割和顶点分析技术,获得三组的校正后海马体积和海马表面模型,分别进行体积和形状的组间比较。结果体积比较显示PD组与对照组之间的左右侧海马体积均差异无统计学意义（左侧P=0.90,右侧P=0.19）,PSD组与对照组之间的左右侧海马体积也差异无统计学意义（左侧P=0.12,右侧P=0.25）;形状分析显示PD和PSD组的双侧海马局部区域较对照组存在萎缩,PD组以左侧海马头部（CA1区）明显,PSD组以左侧海马体部（CA3区）明显。结论PD与PSD患者的海马存在容易被常规体积测量方法所忽略的形状改变,其形状改变模式的区别可能有助于疾病的早期诊断、鉴别和探讨疾病间的潜在联系。

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
