确定青年时期血压模式与日后的心血管病事件的关系,有利于鉴别易患心血管病的年轻人。该研究旨在确定临床随访期间长期血压变异性和年轻至中年血压变化程度是否与中年后心血管病全因死亡率相关,而且是否独立于年轻时平均血压和中年时单一血压测量结果。实验设计:该前瞻性队列研究纳入了1985年3月至1986年6月参加年轻人冠状动脉风险发展研究的社区非洲裔美国人和白人样本3394人。

1 Introduction Hypertension and cerebrovascular disease incidence and prevalence rise dramatically with age, owing to longer exposure time to age-associated alterations in vascular function and structure and cardiovascular risk factors. This chapter is aimed at connecting age-related alterations in vascular function and structure to the resultant target organ damage, and to raise awareness of unique presentations and treatment strategies for hypertension and stroke in older adults.

The aim of this research paper was to identify whether the water quality had been influenced either by the natural environment or by anthropogenic activities or both in the municipality of Linares, the second largest city of the State of Nuevo Leon, NE Mexico. The superficial water (Pablillo River) and the groundwater quality (from a fractured and a porous aquifers hydraulically interconnected) were determined by comparing their chemical composition with maximum permissible limits for water consumption and irrigation use. A hydrogeochemical modeling was performed to identify the distribution of aqueous species responsible for the presence of some dissolved or precipitated mineral species, as well as an identification of geochemical factors responsible of superficial and groundwater quality. A canonical correspondence analysis was allowed to determine if the natural environment and/or anthropogenic activities were responsible for water quality. The parameters analysed in both aquifers, as well as in the Pablillo River, were total solids, suspended solids, nitrate, and chloride;barium and mercury were present in both aquifers. As a natural influence, the predominant mineral species are as following: under-saturated anhydrite (porous aquifer), over-saturated aragonite, calcite, dolomite, and gypsum (both aquifers and Pablillo River), barite and whiterite (only in fractured aquifer). The geochemical factors responsible for natural contamination were rock dominance (fractured aquifer), and evaporation dominance (porous aquifer, Pablillo River). On the other hand, anthropogenic activities such as changes in soil use and the presence of point (old municipal landfill, pig farms, barite deposit), and diffuse (agricultural areas, septic tanks and latrines) pollution sources had influence in the presence of contaminants such as total and fecal coliforms, nitrates, chlorides, mercury and barium. Several control and remediation strategies should be taken into account to prevent

肾动脉射频消融术（radiofrequency ablation of the renal arteries,RF-ABL）已被证明能降低已接受降压药治疗但疗效不佳的高血压患者的血压。然而,现在仍然有很多疑问关于RF-ABL怎样做到不依赖药物治疗而影响血压,和是否有必要完全去肾神经来最大限度地降低血压。为了明确这些问题,本研究检测自发性高血压大鼠（spontaneously hypertensive rats,SHR）行近端肾动脉RF-ABL后对心血管、
