非酒精性脂肪肝辨证分型与体重指数、血脂的关系

目的:通过对非酒精性脂肪肝(NAFLD)人群进行中医辨证分型并探讨与体重指数、血脂的关系,为中西医结合防治NAFLD提供客观理论依据。方法:以2011年1～6月在上海中医药大学附属曙光医院健康体检人群中符合NAFLD诊断标准的602例为研究对象,分析其不同分型与体重指数、血脂的关系。结果:NAFLD人群从中医各证型分布来看,以肝郁脾虚证最多见,肝肾亏虚证最少;痰瘀互结型和湿热内蕴型的肥胖率最高,其组间差异有统计学意义(P<0.05);从血脂指标统计来看,各组TG有不同程度的升高,但以痰瘀互结型升高显著;TC亦有不同程度的升高,但以肝肾亏虚型升高显著;LDL-C的升高主要集中在肝郁脾虚组中;HDL-C各组间比较无显著性差异。结论:NAFLD辨证分型与体重指数关系密切,与TG、TC、LDL-C关系亦密切,此可为中西医结合防治NAFLD提供客观理论依据。     

64层螺旋CT灌注成像对肝硬化血流特点的研究

目的采用64排螺旋CT灌注成像测定肝脏灌注指标,研究肝硬化程度与肝脏灌注参数动态变化的关系。方法正常组15例,肝硬化患者50例,并根据Child-Pugh分级方法分为A、B、C级。对15例正常组和50例肝硬化患者分别进行64排螺旋CT肝脏灌注扫描。利用肝脏灌注软件进行数据处理获得肝脏灌注参数。结果肝动脉灌注量:除正常组与A级组、B级组与C级组比较差异无统计学意义外,正常组与B、C级组之间比较差异均具有统计学意义(P<0.05,P<0.01);门脉灌注量:正常组、A、B及C各级患者相比差异均有统计学意义(P<0.05)。肝总血流量:A级组与正常组比较差异无统计学意义(P>0.05),B级组和C级组患者与正常组及A级组比较、C级组与B级组患者比较差异均有统计学意义(P<0.05);肝灌注指数:A、B、C各级组与正常组相比差异有统计学意义(P<0.05);A、B、C各级组间比较差异有统计学意义(P<0.05)。结论CT灌注成像能很好的反映肝硬化的血流灌注特点,提供有价值的血液动力学信息,为临床进一步准确评估病情、判断预后以及决定治疗方案提供有力的依据。     

浅析心肌活动指数用于心力衰竭中医辨证分型中的临床效果

分析在心力衰竭患者的中医辨证分型中心肌活动指数(Tei指数)的应用价值。以我院收治的心力衰竭患者80例设为研究组,选取同期于我院进行体检的健康者50例作为对照组,并对研究组患者进行中医辨证分型,包括气阴虚型(A组)、气虚血瘀型(B组)、心肾阳虚型(C组)、阳虚水泛型(D组),每组均为20例,分析所有患者的Tei指数以及心动图观察指标。与对照组相比,研究组的Tei指数明显较高(P0.05);A组、B组、C组及D组的EF、DT、E/A、LVDD等相比,差异不存在显著性(P0.05),四组的Tei指数相比,差异显著(P0.05)。在心力衰竭患者中,Tei指数不仅能够对心肌功能进行综合评价,在中医辩证分型中的应用价值也较高。     

经颅多普勒对2型糖尿病患者脑血管病变的评估价值

目的探讨经颅多普勒(TCD)检测2型糖尿病脑血管早期病变的临床应用价值。方法将60例2型糖尿病无微血管病变临床症状的患者分为A组(病程≥10年)、B组(病程<10年),与年龄相近的30例对照组(C组)接受经颅多普勒(TCD)检查,对比分析各组人群大脑中动脉(MCA)、颈内动脉(ICA)末段、大脑前动脉(ACA)、基底动脉(BA)的平均血流速度、搏动指数(PI)及频谱图像的差异。结果 A组、B组患者与C组间平均血流速度比较显著升高(P均<0.01),PI基底动脉A组与B组间无显著差异(P>0.05),其余A组、B组患者和C组间脑动脉的PI值均显著升高(P<0.01);糖尿病组(A组+B组)脑血管硬化较C组明显(P<0.05),脑血管异常也较C组明显(P<0.01)。结论 TCD检测无症状2型糖尿病脑血管病变具有良好的敏感性,可以为及时制定干预治疗措施提供依据。     

肝硬化患者心脏血流动力学变化的研究

对45例肝炎后肝硬化患者作了心脏血流动力学方面的检测,结果发现每分输血量(Co)、每搏输血量(SV)、心脏指数(CI)、心搏指数(SVI)均低于正常对照组(P<0.05～0.001),总外周阻力(TPR)无明显变化(P<0.05);Co、SV、CI、SVI TPR在Chil A、B、C级之间有显著差异(P>0.05～0.001),其关系:Co、SV、CI、SVI为 A级>B级>C级,TPR为C级>B级>A级。还发现CO、SV、SV、CI、TPR与门脉高压程度有明显关系(P<0.05～0.01)。并认为肝炎后肝硬化患者心脏血液动力学变化可能与心肌收缩功能损害有关。     

彩超下肝硬化门脉血流动力学改变与食管静脉曲张破裂出血的关系研究

目的探讨肝硬化时门脉血流动力学改变与食管静脉曲张破裂出血(EVB)的关系,寻求预测EVB的方法。方法用彩色多普勒超声测定正常人(A组)、肝硬化-无食管静脉曲张(B组)、肝硬化-食管静脉曲张无出血(C组)和肝硬化-食管静脉曲张合并出血(D组)4组,患者门静脉血管内径、血流速度、血流量3个血流动力学参数,对4组数据进行对比分析。结果与A组正常人比较,肝硬化3组患者门静脉内径明显增宽(P<0.01),血流量明显增加(P<0.05),血流速度明显减慢(P<0.01)。D组与B、C组相比,门静脉血流速度有显著性增加(P<0.05)。结论门静脉血流速度减慢与EVB的发生有关,动态监测门静脉血流速度的变化可望成为预测EVB发生的有效手段。

2型糖尿病合并非酒精性脂肪肝的临床特点及危险因素分析

目的探讨2型糖尿病(T2DM)合并非酒精性脂肪肝(NAFLD)的临床特点及其相关危险因素。方法随机抽取我院已建立健康档案的糖尿病患者200例,根据是否合并非酒精性脂肪肝分为两组,比较T2DM合并NAFLD(A组,n=114)与T2DM不合并NAFLD(B组,n=86)患者之间的临床特征,探讨影响NAFLD的危险因素。结果两组患者体重指数(BMI)、腰围(WC)、舒张压(DBP)、甘油三酯(TG)、低密度脂蛋白胆固醇(LDL-C)、血尿酸(UA)、血清丙氨酸转氨酶(ALT)、空腹血糖(FBG)水平比较差异有统计学意义(P<0.01或P<0.05);A组代谢综合征、肥胖症、脂代谢紊乱、冠心病、高血压病的发生率明显高于B组(P<0.01或P<0.05)。Logistic回归分析显示BMI、TG、UA对糖尿病合并NAFLD的发生有显著影响(均P<0.01)。结论 2型糖尿病合并NAFLD易发生于肥胖、血脂紊乱、胰岛素抵抗人群,2型糖尿病患者的BMI、TG、UA升高是并发非酒精性脂肪性肝病的危险因素。     

肝硬化门脉高压患者血流动力学及血管活性物质与肝功能的相关性研究

目的探讨门静脉血流动力学指标与肝功能Child-Pugh分级的关系。方法选择确诊为肝硬化门脉高压患者120例,依据肝功能Child-Pugh分级标准分为A级(44例)、B级(48例)、C级(28例)三组,应用彩色多普勒超声检测三组患者门静脉内径、血流速度并计算血流量;观察临床症状、生化指标[总胆红素(TBIL)、白蛋白(ALB)、凝血酶原时间(PT)]及血管活性物质[内皮素-1(ET-1)、一氧化氮(NO)、胰高血糖素(GLU)]的变化。结果门静脉内径比较:C级明显高于A级及B级,三组间差异有统计学意义(P<0.01);门静脉血流速度比较:C级与A级、B级比较差异有统计学意义(P<0.01),但A级与B级比较差异无统计学意义(P>0.05);门静脉血流量比较:C级明显高于A级及B级,三组间差异有统计学意义(P<0.01)。随着Child-Pugh分级由A→B→C递增,C级的ET-1、NO及GLU含量明显高于A级及B级,三组间差异具有统计学意义(P<0.01)。三个指标的含量与肝功能Child-Pugh分级呈正相关。结论门静脉系统血流状态可能在一定阶段受到某种稳定机制的调节,随着肝功能损害程度和血管活性物质代谢障碍的加重,这种稳定机制最终发生明显改变;同时门静脉血流动力学的改变、血管活性物质含量的增加也反映了肝功能损害程度。

Microenvironment of Liver Regeneration in Liver Cancer

The occurrence and development of liver cancer are essentially the most serious outcomes of uncontrolled liver regeneration. The progression of liver cancer is inevitably related to the abnormal microenvironment of liver regeneration. The deterioration observed in the microenvironment of liver regeneration is a necessary condition for the occurrence, development and metastasis of cancer. Therefore, the use of a technique to prevent and treat liver cancer via changes in the microenvironment of liver regeneration is a novel strategy. This strategy would be an effective way to delay, prevent or even reverse cancer occurrence, development and metastasis through an improvement in the liver regeneration microenvironment along with the integrated regulation of multiple components, targets, levels, channels and time sequences. In addition, the treatment of "tonifying Shen (Kidney) to regulate liver regeneration and repair by affecting stem cells and their microenvironment" can regulate "the dynamic imbalance between the normal liver regeneration and the abnormal liver regeneration"; this would improve the microenvironment of liver regeneration, which is also a mechanism by which liver cancer may be prevented or treated.
