摘要:目的:研究高血壓病患者過氧化物酶體增殖物激活受體(PPAR)γ2基因Pro12Ala多態性與血糖水平之間的關系。方法:納入177名原發性高血壓患者,其中空腹血糖(FBG)lt;5.6 mmol/L組65例, FBG≥5.6 mmol/L組112例,收集一般資料;分別測定空腹及餐后2小時血糖、胰島素;對PPARγ2 基因Pro12Ala多態性與各臨床變量的關系進行研究。結果:FBGlt;5.6 mmol/L組和FBG≥5.6 mmol/L組Pro和Ala等位基因頻率分別為0.333,0.034及0.602,0.031;PP和PA基因型頻率分別為0.299,0.068及0.571,0.062;無AA型純合子。以體重指數(BMI)分層后,BMIlt;25組內,FBG與PPARγ2基因型相關（P=0.029)。以基因型分組比較,PA組空腹血糖水平和胰島素抵抗指數都低于PP組(Plt;0.05)。結論:成都地區高血壓患者PPARγ2基因Pro12Ala多態性與空腹血糖水平相關,且攜帶Ala基因者空腹血糖水平較低,胰島素抵抗較輕,推測該突變可能有減輕高血壓病患者胰島素抵抗,改善糖代謝異常的作用。Abstract: Objective:To study the association between the Pro12Ala polymorphism in peroxisome proliferatorsactivated receptorγ2 ( PPARγ2 ) gene and blood glucose levels in patients with primary hypertension. Methods：The Pro12Ala polymorphism in PPARγ2 was determined by polymerase chain reactionrestriction fragment length polymorphism (PCRRELP) in 177 subjects with primary hypertension of the Han people in Chengdu of China, including 65 subjects with fasting blood glucose (FBG)lt;5.6 mmol/L and 112 subjects with FBG≥5.6 mmol/L; the clinical characteristics including height, weight, OGTT(0h and 2h) of the subjects were detected and the realationship between the Pro12Ala polymorphism and the clinical characteristics were analysed. Results: The allele frequencies in the group with FBGlt;5.6 mmol/L and FBG≥5.6 mmol/L were 0.333, 0.602 for Pro and 0.034, 0.031 for Ala. The genotype frequencies were 0.299, 0.571 for PP and 0.068, 0.062 for PA, and there was no AA. In the group with BMIlt;25, the Pro12Ala polymorphism was associated with FBG （P=0.029). the Ala allele had a negative relationship to the FPG and insulin resistance index (IRI) (Plt;0.05).Conclusion: The data showed that the Pro12Ala polymorphism was associated with FBG., and The allele Ala probably had benefits to glycometabolic disturbance in patients with primary hypertension by declining insulin resistance.
This study aims to detect early changes of kidney in patients with primary hypertension by 3.0 T functional magnetic resonance imaging (fMRI). 26 patients with primary hypertension (hypertension group) and 33 healthy volunteers (control group) underwent conventional and functional magnetic resonance scans, which included blood oxygen level-dependent (BOLD) MRI, diffusion weighted imaging (DWI) and diffusion tensor imaging (DTI). We measured renal cortical thickness (CT), parenchymal thickness (PT), and functional values of renal cortex and medulla including R2* value, apparent diffusion coefficient (ADC) value and fractional anisotropy (FA) value in each group, and then calculated the cortical/parenchymal thickness ratio (CPR). Compared with those in the control group, CT and CPR in hypertension group were larger (P<0.01), cortical and medullar R2* values increased (P<0.01) whereas medullar FA values decreased (P<0.05). It could be well concluded that noninvasive 3.0 T functional MRI would have important clinical significance in identifying early abnormalities of kidney in hypertension patients.
【摘要】 目的 探討降高血壓藥物聯合抗焦慮抑郁藥物萬拉法新治療老年性原發高血壓伴焦慮抑郁障礙的療效及安全性。 方法 納入2006年10月-2008年10月我院門診和住院診治的老年性原發高血壓伴焦慮抑郁障礙患者100例,隨機分為干預組和對照組。所有患者給予常規降壓藥物治療,干預組另外給予萬拉法新治療,治療12周后評價臨床療效。結果 干預組臨床降壓療效總有效率940%,顯著高于對照組總有效率800%(Plt;005)。兩組患者的收縮壓、舒張壓與治療前比較均顯著改善(Plt;005),干預組患者與對照組比較血壓明顯改善(Plt;005)。干預組臨床抗焦慮抑郁療效總有效率960%,顯著高于對照組總有效率580%(Plt;005)。兩組均無明顯的不良反應。結論 降高血壓藥物聯合抗焦慮抑郁藥物萬拉法新治療老年性原發高血壓伴焦慮抑郁障礙療效肯定,且安全可靠,值得臨床推廣應用。【Abstract】 Objective To investigate the efficacy and safety of antihypertensive drugs combined with antianxiety depression drug venlafaxine for treatment of patients with senile primary hypertension (SPH) and anxietydepression disorder (AD). Methods One hundred SPH patients with AD with were randomly divided into an intervention group and a control group. All cases were given antihypertensive drugs medication,while the intervention group was given venlafaxine. After 12 weeks of treatment,the clinical efficacy was evaluated. Results The antihypertensive efficacy rate in the intervention group was 940%,significantly higher than that of the control group 800% (Plt;005). The systolic blood pressure(SBP)and diastolic blood pressure (DBP) of the two groups significantly improved compared with those before treatment (Plt;005), and the intervention group’ SBP and DBP improved significantly than those of the control group (Plt;005). The total effective rate of antianxiety depression efficacy of the intervention group was 960%, significantly higher than that of the control group 580% (Plt;005). The two groups had no significant adverse reactions. Conclusion For patients with senile primary hypertension and anxietydepression disorder,the combination medication with antihypertensive drugs and venlafaxine was safe,reliable and worthy of clinical application.
ObjectiveTo systematically review the risk factors in elderly patients with primary hypertension with morning blood pressure surge in China, so asto provide references for clinical treatment and prevention of complications.
MethodsSuch databases as PubMed, EMbase, The Cochrane Library (Issue 11, 2013), CNKI, VIP and WanFang Data were electronically searched for the case-control studies about morning blood pressure surge (MBPS) among elderly patients with primary hypertension in China from January 2006 to June 2014 were collected. Literature was screened according to inclusion and exclusion criteria, data were extracted and the methodological quality of the included studies was assessed, and then meta-analysis was conducted using RevMan 5.2 software.
ResultsA total of 16 studies involving 2 007 cases were finally included, of which 956 cases were detected with MBPS. The results of meta-analysis showed that significant differences were found in glucose levels (MD=0.42, 95%CI 0.04 to 0.81, P=0.03), urinary microalbumin levels (MD=23.85, 95%CI 6.64 to 41.07, P=0.007), incidences of cerebrovascular events (OR=1.96, 95%CI 1.25 to 3.08, P=0.004), carotid atherosclerosis (OR=5.13, 95%CI 1.70 to 15.45, P=0.004) and left ventricular hypertrophy (OR=2.49, 95%CI 1.70 to 3.64, P < 0.000 01), left ventricular mass (MD=12.89, 95%CI 3.94 to 21.84, P=0.005), and carotid artery intima-media thickness (MD=0.08, 95%CI 0.02 to 0.14, P=0.009); while no significant difference was found in gender (OR=1.12, 95%CI 0.84 to 1.49, P=0.44), total cholesterol levels (MD=0.01, 95%CI-0.11 to 0.12, P=0.92), and creatinine levels (MD=1.77, 95%CI-1.16 to 4.70, P=0.24) between patients with or without MBPS.
ConclusionCurrent evidence shows that glucose levels, early kidney damage, emergent cerebrovascular events and the reconstruction of the artery and the left ventricle are risk factors of abnormal MBPS in China. However, the above conclusion needs to be verified by further conducting high quality prospective studies.
