Background Hypertensive target organ damage （TOD） is the main reason for mortality or disability in elderly hypertensive patients. The studies on TOD of hypertension in Asia, especially in Chinese elderly hypertensive patients, are very limited. The aim of this study was to evaluate the prevalence and correlative factors of TOD in older Chinese hypertensive inpatients. Methods This is a retrospective survey and data were collected from the computerized medical files of hypertensive inpatients from January of 1993 to December of 2008. The analysis was done on 17 682 inpatients, aged 60 years or older, with a diagnosis of essential hypertension （EH）. The evidence of hypertensive TOD and associated factors with TOD were collected. Results The prevalence of any hypertensive target organ involvement among these subjects was high. In multivariable Logistic regressions adjusted for potentially confounding factors, older age, male gender, diabetes, EH grade 3, systolic blood pressure （SBP）, and low-density lipoprotein cholesterol （LDL-C）, were independently associated with coronary artery disease. Age, duration of EH, EH grade 3, SBP, pulse pressure （PP）, and homocysteine （Hcy） were independently associated with cerebrovascular disease. Age, diabetes, duration of EH, EH grade 3, SBP, PP and estimated glomerular filtration rate （eGFR） were independently associated with chronic kidney disease. Male gender, EH grade 3 and SBP were independently associated with aortic dissection. Conclusions The prevalence of hypertensive TOD is high in older Chinese hypertensive inpatients. Various cardiovascular risk factors are associated with hypertensive TOD. The level of SBP and severe hypertension （grade 3 hypertension） are common independent risk factors of TOD.

A Convenient Synthesis of Acyclic 1,18-Diketones

中国化学会第四届有机化学学术会议

作者： WU.xin-liang guo,Yuan YANG, Bing-Qin SHI, Zhen (Department of Chemistry, Northwest University, Xi''an 710069)

＜正＞Acyclic diketones containing 16 methylenes are important precursors of some macrocyclic perfume compound and an useful class of compounds in view of the distinct structure feature and wide utility in medical industry, dyeing industry and organic synthesis. A number of methods have been reported so far for the synthesis of dike-tones. However, most of these methods suffer disadvantages with respect to convenience, selectivity, or efficiency and have limited applicability in preparing diketones containing less than 7 methylenes. We reported the reaction of benzimidazolium salts with Grignard reagents in which a novel synthetic method for ketones was provided. In extention of our method, the reaction of bis-benzimidazolium salts （compound 2） with Grignard reagents was studied, and a convenient synthetic method for the preparation of four 1,18-diketones was provided. The structures were confirmed by NMR, IR and MS spectra. The synthetic route is shown in Scheme 1.
