摘要:目的:研究高血压病患者过氧化物酶体增殖物激活受体(PPAR)γ2基因Pro12Ala多态性与血糖水平之间的关系。方法:纳入177名原发性高血压患者,其中空腹血糖(FBG)lt;5.6 mmol/L组65例, FBG≥5.6 mmol/L组112例,收集一般资料;分别测定空腹及餐后2小时血糖、胰岛素;对PPARγ2 基因Pro12Ala多态性与各临床变量的关系进行研究。结果:FBGlt;5.6 mmol/L组和FBG≥5.6 mmol/L组Pro和Ala等位基因频率分别为0.333,0.034及0.602,0.031;PP和PA基因型频率分别为0.299,0.068及0.571,0.062;无AA型纯合子。以体重指数(BMI)分层后,BMIlt;25组内,FBG与PPARγ2基因型相关(P=0.029)。以基因型分组比较,PA组空腹血糖水平和胰岛素抵抗指数都低于PP组(Plt;0.05)。结论:成都地区高血压患者PPARγ2基因Pro12Ala多态性与空腹血糖水平相关,且携带Ala基因者空腹血糖水平较低,胰岛素抵抗较轻,推测该突变可能有减轻高血压病患者胰岛素抵抗,改善糖代谢异常的作用。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.
高血压是我国重点防治的心血管疾病, 血压的控制率备受关注。在一些血压控制不良的患者中睡眠呼吸暂停是导致顽固性高血压的重要原因。以睡眠过程中反复、频繁出现呼吸暂停和低通气为特点的睡眠呼吸暂停低通气综合征( sleep apneahypopnea syndrome, SAHS) 自20 世纪80 年代以来也受到广泛关注, 临床和基础研究取得了迅速发展。目前, 多项临床、流行病学和基础研究证实SAHS可以导致和/ 或加重高血压, 与高血压的发生发展密切相关。
Hypertension is the primary disease that endangers human health. A convenient and accurate blood pressure measurement method can help to prevent the hypertension. This paper proposed a continuous blood pressure measurement method based on facial video signal. Firstly, color distortion filtering and independent component analysis were used to extract the video pulse wave of the region of interest in the facial video signal, and the multi-dimensional feature extraction of the pulse wave was preformed based on the time-frequency domain and physiological principles; Secondly, an integrated feature selection method was designed to extract the universal optimal feature subset; After that, we compared the single person blood pressure measurement models established by Elman neural network based on particle swarm optimization, support vector machine (SVM) and deep belief network; Finally, we used SVM algorithm to build a general blood pressure prediction model, which was compared and evaluated with the real blood pressure value. The experimental results showed that the blood pressure measurement results based on facial video were in good agreement with the standard blood pressure values. Comparing the estimated blood pressure from the video with standard blood pressure value, the mean absolute error (MAE) of systolic blood pressure was 4.9 mm Hg with a standard deviation (STD) of 5.9 mm Hg, and the MAE of diastolic blood pressure was 4.6 mm Hg with a STD of 5.0 mm Hg, which met the AAMI standards. The non-contact blood pressure measurement method based on video stream proposed in this paper can be used for blood pressure measurement.
ObjectiveTo explore and compare the therapeutic effects of neuro-endoscopic and craniotomic hematoma evacuation for hypertensive hematomas in the basal ganglia region. MethodsEighty-six patients with hypertensive hematomas in the basal ganglia regions treated between January 2010 and September 2014 were divided into neuro-endoscopy and craniotomy groups randomly with 43 in each. Hematoma was removed directly under neuro-endoscope in the endoscopic group, while it was removed under the operating microscope in the craniotomy group. The average operation bleeding amount, residual hematoma after operation, hematoma evacuation rate, the changes of National Institutes of Health Stroke Scale (NIHSS) and Barthel index (BI) scores before operation, 1 and 3 months after operation were compared between the two groups. All data were analyzed statistically. ResultsThe average amount of operation bleeding was (127±26) mL, postoperative residual hematoma was (6±4) mL, and the hematoma clearance rate was (86±9)% in the neuro-endoscopy group, while those three numbers in the craniotomy group were respectively (184±41) mL, (11±6) mL, and (72±8)%, with all significant differences (P < 0.05). The NIHSS and BI scores were not significantly different between the two groups before surgery (P > 0.05). Seven days, one month and three months after surgery, the NIHSS score was significantly lower, and the BI score was significantly higher in the neuro-endoscopy group than the craniotomy group (P < 0.05). ConclusionNeuro-endoscopic surgery for hypertensive hematomas in basal ganglia region is proved to have such advantages as mini-invasion, direct-vision, complete clearance and good neural function recovery after surgery, which is a new approach in this field.

Methods One hundred and sixty patients with hypertensive crises admitted to our department from January 2008 to December 2009 had been diagnosed and treated. Results There were 134 patients with hypertensive emergencies (HE) and 26 patients with hypertensive urgencies(HU)in accordance with those principle. Cardiocerebralvascular diseases were the main symptom of HE including stroke, acute coronary syndrome and acute left ventricular failure. According to those principles,the emergency management was carried out, accuracy evaluation and effective management of hypertensive crises could reduce wrong diagnosis and treatment,decrease mortality and improve prognosis. Conclusion The principle of evaluation and management of hypertensive crises could guide the emergency management of hypertensive crises and obtain better prognosis.
Objective To investigate the current prevalence of cerebral stroke and hypertension in Ganzi Tibetan state, so as to control stroke and hypertension in future. Methods A representative people sample of Kangding, Dege, Ganzi, Litang and Batang county was selected through randomized cluster sampling. Data of demographic characteristics, hypertension and stroke status were collected by face-to-face interview. Results 5 049 people were included, of which 48.6% were male, and 51.4% were female. The prevalence rate of hypertension and stroke were 23.4% and 1 894/100 000 respectively. The population with hypertension had high prevalence of stroke. The prevalence increased along with the age. Conclusions The prevalence of hypertension and stroke is high in Ganzi Tibetan state. The causes may be ascribed to special geography surroundings and life style. It is very important to pay more attention to prevent and control of hypertension and stroke in this area.
