Objective: To explore the role of cytokines on the pathogenesis of atherosclerosis, and the effect of Tongmai Jiangzhi oral liquid (通脉降脂口服液,TMJZ) on cytokines through observing serum P-se-lectins (Ps), von Willebrand (vWF), and D-dimer (D-D) in atherosclerosis (AS) patients. Methods: Sixty-three AS patients were randomly divided into the treated group (n = 33, treated with TMJZ, 10 ml each time, three times a day) and the control group (n = 30, treated with Lovastatin, 10 mg, once daily). The levels of serum lipids (enzymatic methods), Ps, vWF, and D-D were measured before and after 8 weeks of treatment. Results: Serum total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C), apo-protein B-100 (apoB-100) were significantly decreased (P<0.05 or P< 0.01) and high-density lipoprotein cholesterol (HDL-C) was significantly raised (P<0.05) after TMJZ treatment.

Effects of Quyu Xiaoban Capsule(祛瘀消斑胶囊) on Vascular Endothelial Function in Patients with Atherosclerosis

Objective: To evaluate the therapeutic effects of Quyu Xiaoban Capsule (祛瘀消斑胶囊 ,QYXBC) on endothelial dependent vascular relaxation (EDVR) function in patients with atherosclerosis (AS)with ultrasonic technique. Methods: Tested were the endothelial function and blood lipids of 42 patients with AS in the treated group and 30 healthy volunteers in the control group. And re-examination of these parameters was carried out on the AS patients after they had been treated with QYXBC for 10 months. Results: Before treatment, the reactive hyperemia induced changes in artery diameter in the treated group was significantly lower than that in the control group (P＜0.01), while insignificant difference was found between the two groups in response to nitroglycerin. In the treated group after treatment, with D%-R improved significantly (P＜0.01), total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C)decreased by 16.3%, 5.6%, 10.2% respectively and high-density lipoprotein cholesterol (HDL-C) increased by 7.5%. EDVR was correlated negatively with the serum TC, LDL-C concentrations and the baseline brachial diameter (D0) (r = -0.41, -0.66, -0.59, respectively, all P＜0.01), but correlated positively with HDL-C (r = 0.62, P＜0.05). The ameliorative extent of EDVR was correlated positively to the decreased magnitude of TC and LDL-C concentrations ( r = 0.67,0.59, both P＜0.01 ). Conclusion: QYXBC can lower the level of blood lipids and improve significantly EDVR function.     

Effects of Xuezhikang capsule on blood lipids, platelet activation and coagulation-fibrinolysis activity in patients with hyperlipidemia

Objective: To investigate the effects of Xuezhikang capsule (XZK) on blood lipids level, platelet activation and coagulation-fibrinolysis activity in patients with hyerlipidemia.Methods: Seventy-six patients of hyperlipidemia were randomly divided into two groups, the XZK group (n = 38) treated with XZK 600mg, taken two times per day and the Simvastatin (SIM) group (n = 38) treated with SIM 20mg per day, with the treatment lasting 8 weeks for both groups. Levels of fasting serum lipids, including total cholesterol (TC), triglyceride (TG), high and low density lipoprotein cholesterol (HDL-C and LDL-C), plasma GMP-140, fibrinogen (FIB), tissue plasminogen activator (t-PA), plasminogen activator inhibitor type-1 (PAI-) and prothrombin time (PT) were all measured before and 8 weeks after treatment. Data were compared before and after treatment and also compared with those measured in 20 healthy subjects of control.Results: Before treantment the levels of TC, TG and LDL-C were obviously higher and HDL-C level was significantly lower in hyperlipidemia patients than those in healthy subjects (P<0.05 orP<0.01). After 4–8 weeks of XZK treatment, the levels of TC, TG, LDL-C and FIB and activities of GMP-140 and PAI-1 were obviously lowered (P<0.05 orP<0.01). But in the SIM group there was no obvious change in FIB (P>0.05), instead it showed obvious increase of HDL-C and decrease of TC and LDL-C after treatment (P<0.05 orP<0.01).Conclusion: XZK could inhibit platelet activity and improve coagulation-fibrinolysis function, besides its lipids lowering effect.

Objective: To observe the effect of Gengnianchun Recipe (GNC) on bone mineral density (BMD), bone biomechanical parameters and serum lipid level in the bilaterally ovariectomized (OVX) rats and to explore the prophylactic and therapeutic action of GNC on ovariectomy induced osteoporosis and hyperlipidemia.Methods: OVX SD rats, 10 –12 months old, were divided into different groups and fed with GNC 2 g/d, GNC 1 g/d and Nilestriol 0. 125 mg/week, respectively for 4 months to observe the change of BMD and bone biomechanical parameters of the lumbar vertebrae, and the serum levels of total cholesterol (TC), triglyceride(TG), high-density lipoprotein cholesterol (HDL-C) and low-density lipoprotein cholesterol (LDL-C), and to compare the effect of the two drugs on the morphology of the uterus.Results: There was marked reduction in BMD and biomechanical parameters in lumbar vertebrae (P< 0.01) and increase of serum TC and LDL-C levels (P< 0. 01) in rats after OVX. GNC or Nilestriol significantly improved the decreased BMD and biomechanical parameters of the lumbar vertebrae (P< 0.05 orP< 0.01), and reduced the serum TC and LDL-C levels (P< 0.01). In the Nilestriol group, the wet weight of uterus got increased obviously (P< 0.01), the number of uterine glands increased, uterine columnar epithelium thickened, and the mitotic figures in the epithelial stroma and myointimal cells augmented. But no such effect in wet weight and morphology of uterus was found in the GNC group.Conclusion: GNC could increase the BMD and biomechanical parameters of the lumbar vertebrae, reduce the serum TC and LDL-C levels, yet produce no adverse reaction in stimulating proliferation and hypertrophy of uterus.

[目的] 考察清脑益智方（QNYZF）对血管性痴呆（VaD）大鼠脑血流量（CBF）及血脂水平的影响。[方法] 选用健康雄性SD大鼠,随机分为假手术组、模型组、QNYZF低、中、高剂量组,采用双侧结扎颈总动脉（2-VO）法复制大鼠VaD模型。灌胃给药4周后,采用MOOR激光多普勒血流监测仪检测大鼠CBF,测完后取血、离心,收集血清,通过全自动生化仪检测血清中总胆固醇（TC）、三酰甘油（TG）、低密度脂蛋白胆固醇（LDL-C）和高密度脂蛋白胆固醇（HDL-C）含量。[结果] 与假手术组比较,模型组大鼠CBF降低（P<0.05）;与模型组比较,给予QNYZF干预后,中、高剂量组大鼠CBF升高（P<0.05或P<0.01）。与假手术组比较,模型组大鼠血清中TC、TG和LDL-C含量升高（P<0.05）,而HDL-C含量无明显变化（P>0.05）;给予QNYZF干预后,各剂量的QNYZF均可降低VaD大鼠血清中TC、TG和LDL-C含量（P<0.05或P<0.01）,而对HDL-C含量无明显影响（P>0.05）。[结论] QNYZF可有效改善VaD大鼠的CBF,其作用机制与降低血脂水平、改善血脂异常有关。     

急性脑梗死患者颈动脉内膜中层厚度性别差异性研究

目的 探究急性脑梗死患者颈动脉内膜中层厚度(intima-media thickness,IMT)的性别差异,为脑梗死患者诊断和防治的性别差异提供参考。方法 选择急性脑梗死患者193例,依据性别将193例急性脑梗死患者分为两组:男性急性脑梗死组94例,女性急性脑梗死组99例。检测两组受试者血浆同型半胱氨酸(homocysteine,Hcy)、总胆固醇(total cholesterol,TC)、甘油三酯(triglycerides,TG)、高密度脂蛋白胆固醇(high density lipoprotein cholesterol,HDL-C)、低密度脂蛋白胆固醇(low density lipoprotein cholesterol,HDL-C)水平,采用彩色多普勒超声测定两组受试者颈动脉IMT,比较两组间各指标的差异,分析颈动脉IMT性别差异性原因。结果 男性急性脑梗死患者组颈动脉IMT较女性急性脑梗死组厚,差异有统计学意义(P<0.05);男性急性脑梗死组血浆Hcy水平、LDL-C水平及吸烟率均高于女性急性脑梗死组,差异有统计学意义(P<0.05);女性急性脑梗死组HDL-C水平高于男性急性脑梗死组,差异有统计学意义(P=0.000);多变量Logistic回归显示血浆高Hcy、LDL-C水平,高吸烟率以及低血浆HDL-C与男性显著相关(P<0.05);多元线性回归分析进一步揭示男性、年龄、Hcy、吸烟与颈动脉IMT独立相关。结论 男性急性脑梗死患者组颈动脉IMT较女性急性脑梗死组厚,这可能与血浆Hcy水平、吸烟不良行为密切相关。     

甘草酸对非酒精性脂肪性肝炎大鼠治疗效果研究

目的 研究甘草酸对非酒精性脂肪性肝炎（NASH）大鼠的治疗效果及其作用机制。方法 雄性SD大鼠40只随机分为5组：正常组,模型组,低、中、高剂量甘草酸治疗组（60、120、180mg/kg）,以高脂饮食喂养16周构建大鼠NASH模型,于造模第7周起进行不同剂量甘草酸治疗10周,HE染色观察肝组织病理学变化,并对总胆固醇（TC）、甘油三酯（TG）、高密度脂蛋白胆固醇（HDL-C）、低密度脂蛋白胆固醇（LDL-C）、天门冬氨酸氨基转移酶（AST）、丙氨酸氨基转移酶（ALT）、丙二醛（MDA）、超氧化物歧化酶（SOD）及还原型谷胱甘肽（GSH）进行检测。结果 高脂饮食诱导的NASH大鼠模型中,肝组织可见肝细胞脂肪病变,血清中TC、TG、LDL-C、AST、ALT及MDA明显升高,HDL-C、SOD及GSH显著降低;而经过中、高剂量甘草酸治疗后发现,肝细胞脂肪病变程度降低,血清中TC、TG、LDL-C、AST、ALT及MDA明显降低,HDL-C、SOD及GSH明显升高,与模型组相比差异均具有统计学意义（P<0.05）。结论 甘草酸能够经过抑制氧化应激损伤、改变血脂水平来改善NASH大鼠肝功能及抑制肝脏病变程度,对NASH治疗具有潜在的临床意义。     

胆红素对兔实验性动脉粥样硬化形成的预防作用

目的　探讨体内的强抗氧化剂—血清胆红素防止动脉粥样硬化 (AS)的作用及机制。　方法　在新西兰兔食饵性 AS模型上 ,观察胆红素治疗性给药对氧化修饰低密度脂蛋白 (Ox L DL)、胆固醇 (TC)、甘油三酯 (TG)、低密度脂蛋白 (L DL )等水平变化及主动脉壁 AS斑块形成的影响。血清胆红素采用重氮法测定 ,Ox L DL采用EL ISA法测定 ,TC、TG采用酶法测定 ,高密度脂蛋白 (HDL)采用选择性抑制法测定 ,L DL 通过 Friedward公式计算。　结果　 AS模型组的血清胆红素较正常对照组及胆红素处理组降低 (P<0 .0 5 ) ,胆红素处理组的 Ox L DL较对照组增高但低于 AS模型组 (P<0 .0 1 ) ,胆红素处理组与 AS模型组的 TC、TG、L DL 等水平差异无显著性 (P>0 .0 5 )。　结论　适当提高体内胆红素浓度以增加体内抗氧化能力 ,有利于抑制 L DL 氧化形成 Ox L DL,防止泡沫细胞形成 ,可能是防治 AS的又一重要途径
